How Parents ‘Guarantee’ Baby’s Gender’ Using the Babydust Conception Hack – Newsweek

Discovering the sex of your baby can be one of the most exciting parts of your pregnancy. But what if someone said you could determine your baby's sex when you're trying to conceive?

Kathryn Taylor, author of The Babydust Method: A Guide to Conceiving a Girl or a Boy, has suggested that the timing and frequency of intercourse in relation to ovulation can be used as a sex selection method.

[There is no blah blah] To find out more, Newsweek has spoken to Taylor, fertility and gynecology experts, and parents who have tried the method.

Taylor told Newsweek that the Babydust method relies on factors that may affect whether an X chromosome or Y chromosome sperm fertilizes an egg. The three key components are timing, frequency and, most importantly, monitoring your luteinizing hormone (LH) levels, she added.

"I was my own first test subject," Taylor said. "I had a son first and a daughter second, just as I had planned. Then I tested it on family and friends and was nearly 100% successful."

Taylor recommends that women monitor their LH levels using basic test strips at least twice a dayideally once in the morning and once in the eveningfor three menstrual cycles before they try to conceive. At major online retailers, a pack of 100 basic LH test strips costs around $35.

She said taking these tests would help determine when your LH levels are surging, which typically occurs approximately 24 hours prior to ovulation. By testing from the fifth day of your cycle until you record a "positive" LH surge for three consecutive months, you will have a better chance of predicting your next ovulation.

The Babydust method, having sexual intercourse once two-to-three days prior to ovulation will likely result in conceiving a baby girl. Alternatively, having sex twice - once on the day of your ovulation and the second time approximately 24 hours after - will likely result in a baby boy.

The difference between frequency is based on studies that Taylor references in the book that revealed that "two acts of intercourse 24 hours apart will alter the uterine environment in favor of Y sperm."

According to Taylor, based on the reported "sways" shared by real couples, "the success rate has been consistently at 87% for both girl and boy sways over the past 5 years."

"Every result that is reported is evaluated to make sure the couple followed the method perfectly," she reassured .

Taylor believes that "some couples have said that this method has actually helped them conceive faster." She explained that by regularly monitoring their LH levels, couples are aware of the woman's most fertile days, which helps them time intercourse accordingly and "focus their efforts on the right days."

With that in mind, Taylor emphasized that "this method is not a guarantee," advising couples "to go into this with a positive attitude." "If they keep in mind that the Babydust method is a way to increase your chances, then it lessens the possible disappointment," she suggested.

Antoine Abu Musa, chief medical officer at online IVF clinic NOW-fertility, shared that although the timing and frequency of intercourse have been widely considered as key factors of sex selection, "there is no scientific objective evidence that it works."

Interestingly, Abu Musa suggested that maternal hormonal levels on the day of fertilization can play a role in determining the sex of the embryo. "More females at birth have been associated with various forms of stressful events and circumstances during or prior to pregnancy," he told Newsweek. "Unfortunately, the research in this field is limited and sometimes contradictory," he added.

Abu Masa also believes that ovulation days differ each month and that monitoring ovulation for three months before applying the Babydust method might not be helpful in predicting your future ovulation. He also shared that even after tracking LH levels for three cycles, timing and limiting the intercourse to a certain day of the cycle "might lead to missing the window of fertilization" altogether.

According to Abu Masa, the only reliable and accurate method of sex selection is the PGT-A, a genetic test performed on embryos fertilized through invitro fertilization (IVF). Dr. Zev Williams of Columbia University Fertility Center suggested that this approach has a 99 percent chance of conceiving a baby of a desired sex. However, it comes with a steep price according to AdvancedFertility, the average cost of one IVF round with a PGT test costs approximately $15,500.

According to U.K. law, however, testing an embryo for the purposes of sex selection was made illegal by the Human Fertilisation and Embryology Act 2008. As such, the only legal way parents can use a PGT-A test and IVF to select the sex of a baby in the U.K. is by proving that there are significant genetic anomalies associated with the parents having a child of a certain sex.

Dr Evangelia Elenis, chief medical advisor at Tilly and chief physician in obstetrics and gynecology, believes that "the reasoning behind the [Babydust] method makes sense from a theoretical perspective, but not in a practical reality."

"As far as I know, there is no conclusive scientific proof for the Babydust method," she told Newsweek.

Elenis encourages couples to remember that menstrual cycles "are not perfectly regular and calculating averages may not work." Still, she explains that tracking LH levels and predicting ovulation can certainly help in conceiving. However, Elenis warns that so far, "there is no scientific proof that you can control whether a sperm that carries an X or a Y chromosome will fertilize the egg."

Newsweek also spoke to a few members of The Babydust Method Facebook group about their experiences regarding whether or not they were successful and how long and strictly they followed the method.

Earlier this year, Kayla George welcomed a baby boy as a result of a "successful sway" based on the Babydust Method. "We are so thankful for this method," the mother shared.

She described that the "method looked to be the most reliable and cost efficient" compared to other sex selection techniques and methods commonly discussed on the internet. George shared that she and her partner followed the instructions attentively and that it took her two cycles to get a positive test result. As per Taylor's guidance, George tracked her LH levels twice a day for three months prior to trying to conceive.

"We have five wonderful daughters, and we were just hoping to be lucky enough to add a little boy to our family. If we didn't fall pregnant, or if it was another little girl we would have been okay," she shared.

Meanwhile, one woman shared her experience of a "boy sway fail," which happened despite her strictly following all the instructions, tracking her LH levels and even consulting with the author of the book.

Liana Averbeck is currently 18 weeks pregnant with twin girls, after having tried for three months to conceive a baby boy using the Babydust method.

"All details were discussed with the author and she deemed the sway a perfect boy sway," she shared.

According to Averbeck, she even tracked her body basal temperature (BBT) so as to ensure an accurate prediction of her ovulation in addition to charting her LH levels twice a day.

Regardless, although at first she felt "a little bit of a loss and sadness for not getting one boy," the woman has no regrets: "Using this method, I felt I was learning more about my body and was more confident in conceiving," she told Newsweek. Now, Averbeck described that she feels "blessed" to be pregnant with her baby girl twins.

The woman suspected that the genetics on her husband's side might have played a role as she shared that he "mostly has girls on both sides of the family."

Averbeck also said that she discourages the method "if you cannot bear a 'gender sway fail' and would not want another baby of the same gender."

The conservative ‘What is a woman?’ talking point, explained – The Week

In the wake of the Supreme Court overturning Roe v. Wade, the 1973 decision that established a constitutional right to abortion, a parallel debate has erupted over the use of inclusive pregnancy language. Critics say "omitting the word 'women' to make room for the relatively tiny number of transgender men and people identifying as nonbinary who retain aspects of female biological function and can conceive, give birth, or breastfeed" effectively "erases" women, while supporters of inclusive language call that argument "transphobic" and argue that using such terms "costs us nothing and makes the movement stronger."

Nevertheless, conservatives have weaponized "gotcha"questions like "What is a woman?" or "Can men get pregnant?" Here's everything you need to know:

In a Senate Judiciary Committee hearing this week,University of California, Berkeley law professor Khiara Bridges went viral after Sen. Josh Hawley (R-Mo.) asked her to clarify if her use of the term "people with the capacity for pregnancy" meant "women." "Many women cis women have the capacity for pregnancy, many cis women do not have the capacity for pregnancy," Bridges answered. "There are also trans men who are capable of pregnancy as well as non-binary people who are capable of pregnancy." She went on claim that Hawley's "line of questioning" was "transphobic" and "opens up trans people to violence."

Hawley's question did not come out of a vacuum, however. Right-wingers like conservative podcast host Matt Walsh and theconservative Christian YouTube channel What Would You Sayhave been using the "gotcha" question "what is a woman?" for a few years now, both to troll liberals but also in higher stakes encounters.Sen. Marsha Blackburn (R-Tenn.), for example, asked then-Supreme Court nominee Ketanji Brown Jackson to "provide a definition for the word 'woman'" during her Senate confirmation hearing earlier this year (Jackson ultimately responded that she could not because she is "not a biologist").

Questioning gender is as old as civilization itself. Letters from the 18th century B.C. discovered in Mari, Syria, describe a type of prophet known as an assinn or "man-woman." Historian Edward Gibbon wrote that the teenage Roman Emperor Elagabalus "cop[ied] the manners and dress of the female sex." Court documents from the late 1300s record the interrogation of London prostitute Eleanor Rykener, who confessed to having previously lived as a man under the name "John." More recently, gender critics have argued that while we tend to think of our definition of "woman" as beingthe objective definition, it isn't; it's culturally constructed.

But the question of defining "women" has become particularly seized upon by Republicans since the Roe v. Wadedecision. "Turning their ire on inclusive language is a conscious strategy," argues Vox. "It allows Republicans to misrepresent and minimize the effects of laws like abortion bans, by omitting groups that they affect. Engaging in transphobia also plays well withsome members of the Republican base."

The opposite of a "constructionist" definition of gender would be an "essentialist" definition, one rooted in female biology: "Previously a commonly understood term for half the world's population, the word had a specific meaning tied to genetics, biology, history, politics, and culture," wrote New York Times columnist Pamela Paul in a recent op-ed. "No longer. In its place are unwieldy terms like 'pregnant people,' 'menstruators,' and 'bodies with vaginas.'" Or assoon-to-be-former Rep. Madison Cawthorn (R-N.C.) put it a "woman" is "XX chromosomes, no tallywhacker."

Before they ever reached into congressional hearings and cable news, the debate between these two definitions of womanhood played out in the left-leaning milieus of academia and feminist activism, with "gender critical" feminists labeled "trans-exclusionary radical feminists" or TERFs by their detractors arguing in favor of essentialism. Now the issue has become front and center, as stoked by the "remarkable bad faith" questioning of conservatives, Philip Bump wrote for The Washington Post.

Others, though, argue the whole debate has become a distraction."The truth is, you can be kind. You can be inclusive. You can also be accurate," writer andphilosopher Kate Manne wrote in a recent Substack post pushing back on the circular debate. "You may just have to make a small but necessary moral effort. And, if you are not prepared to do that, you should be corrected when applicable and subject to due criticism. That is not cancellation, to anticipate. It is basic accountability."

Beard Growth: Tips to Speed Up the Process – Medical News Today

Although exercising and eating a nutritious diet may speed up beard growth, the main factors that determine how fully a persons beard will grow are hormones and genetics.

Males start to grow facial hair during puberty. Many of them will notice that their facial hair first begins to grow on the upper lip.

Other areas people may notice early facial hair growth include the chin or the sides of the face near the ears, which people refer to as sideburns.

Facial hair grows differently for everyone. Some individuals may be able to grow a full beard during late stage or even middle stage adolescence. Others may continue to have sparse areas of growth until their late 20s, while some may never experience significant facial hair growth.

This article will explore what factors influence a persons beard growth and whether it is possible for someone to make their beard grow faster.

Genetics and hormones are the main factors that determine how quickly and fully a persons beard will grow. Their lifestyle and habits may also affect how their beard grows.

Testosterone is a hormone that affects the growth of facial hair, and its levels can vary. Males between 19 and 38 typically have a range of 264 to 916 nanograms per deciliter. This represents the 2.5th to 97.5th percentile for testosterone.

Low testosterone can adversely affect beard growth. For males with low testosterone, taking supplements under a doctors supervision may help increase beard growth.

If a persons testosterone levels fall within typical ranges, taking supplements will most likely not affect their beard growth.

Genetics also affect the way a persons beard grows. Some genes make them more prone to growing a fuller beard, while others may only ever be able to grow a sparse or patchy beard or other facial hair.

The health and well-being of a person affect how their whole body functions, including how their beard grows. Even though it is not possible to alter someones genes, lifestyle habits they can adopt may help them achieve a fuller beard.

Exercise improves blood flow, which helps stimulate hair follicle growth. Exercises, such as weightlifting and strength training, may also help boost a persons testosterone levels.

During the day, testosterone levels naturally fluctuate in young males, with a higher level in the morning and a lower level in the afternoon.

Good nutrition from eating a balanced diet may help in growing a beard and staying healthy.

According to a 2015 study, obesity and low testosterone have a bidirectional relationship, meaning that low testosterone can lead to obesity and obesity can lead to low testosterone.

Nutrients, such as zinc, may also be beneficial for testosterone levels. A nutritious diet will not override genetics, but it may help the existing hair grow healthier and fuller. Some foods that can help include:

Some supplements can contribute toward maintaining a persons health in a way that is conducive to growing their beard as fully as their genetic makeup will allow.

A person may wish to take a multivitamin containing iron and zinc if their diet does not provide them with sufficient amounts of these nutrients.

However, there are no supplements that will enable a person to grow a beard if they do not have the genes to do so.

Maintaining a healthy skin care routine, including keeping the beard clean, can positively affect how a persons beard will grow and look.

Exfoliating the face can help remove dead skin cells and debris from around each hair follicle, allowing the hair to grow through the skin unimpeded. Exfoliating can also reduce ingrown hairs under the beard.

Leave-in conditioners for beards can nourish the hair and keep it moisturized. This helps reduce and prevent beard dandruff and makes the beard look fuller. It is best to perform a patch test to find out which products work best for the beard.

As well as being necessary for overall health, sleep can also aid beard growth.

The testosterone levels in males generally increase when they are asleep. A 2015 study found that reducing the amount of daily sleep lowered testosterone levels in healthy young males.

Keeping a beard clean and moisturized can help it appear thicker. However, there is no certain routine with scientific backing that can thicken a growing beard.

However, some anecdotal evidence suggests that olive oil and avocado oil could thicken beards.

It is possible that these may work the way leave-in conditioners do by keeping the beard nourished and moisturized.

Growing a beard depends mostly on a persons genetics.

However, testosterone plays some role in determining how fast and well someones beard will grow.

Making sure to keep testosterone levels within a stable, healthy range by regularly exercising, eating well, getting sufficient, restful sleep, and exfoliating can help a persons beard grow as thick and full as it is naturally able.

The canine behavior of the LGBTQ cabal – Washington Times

OPINION:

This past week, The New York Times published an opinion piece finally admitting that todays LGBTQ cabal of rainbow activists is little more than a misogynistic cult that reduces women to just a mix of body parts and gender stereotypes.

Writing for the Times, columnist Pamela Paul described what she called the fringe lefts misogynist agenda.

The word women, said Ms. Paul, which has, for millennia, been commonly understood by all rational thinking people to denote genetics, physiology, biology and the basic reality of human existence, is now verboten. In place of this word, we now have nonsensical terms that reduce females to their biological functions; words like pregnant people, birthing persons, menstruators and bodies with vaginas.

This logically strained nomenclature has been force-fed to the American public, bemoaned Ms. Paul, as she cited President Bidens cultural lunacy of removing biological sex from the federal register and replacing words such as mothers and women with birthing people and breastfeeders instead.

Women didnt fight this long and this hard only to be told we couldnt call ourselves women anymore. This isnt just a semantic issue; its also a question of moral harm, an affront to our very sense of ourselves, she concluded.

Amen! Welcome to the side of sanity, Ms. Paul.

I have said from the very first days of the LGBTQ movement that this broken worldview could only have one logical end: the complete degradation of what it means to be a human being and that women would be the first to suffer at the hands of this grand lie.

You cant dumb down human identity to nothing but the sum total of human inclinations and retain any modicum of human dignity. If we define ourselves by our subjective desires and not by Gods objective design, our ontology the reality of who we are becomes meaningless, and being a woman means absolutely nothing.

Think about it.

Today our schools teach our youngest girls that women arent real. Our Congress tells women they have no right to their own restrooms, sports or showers. Our corporations proudly defend the cultural appropriation of women by dysphoric men who want to act like something they are not. And todays feminists now pretend a female is a fabrication rather than a biological fact.

The question we should all be asking is this: What could possibly be more degrading than publicly supporting the blackfacing of women in a manner that is just as cartoonish and insulting as it is when white people dress up in literal blackface to mimic and mock people of color?

This is misogynistic. It diminishes the woman to little more than a delusion. It disregards who she truly is. It elevates feelings over facts. It supersedes the rational by supplanting it with the emotional. Moreover, it replaces the reality of the female with the fantasy of those who seek to use her for political gain.

All of this is little more than a placard for a culture a cult of deception and deceit. Its a snapshot of a people who have literally lost their minds.

When your definition of the person becomes little more than the cumulative effect of his or her sexual urges, you are admitting you think those with a given appetite are actually defined by that desire. With a not-so-thinly disguised bigotry, you are saying you think thats just who they are and that their personal identity is nothing more than the totality of their libidinous inclinations. Is this not the ultimate insult to your fellow man? Is this not the grandest slur of what it means to be a woman?

The biblical model is the opposite. It elevates men and women to the highest status of all worldviews. Genesis, as well as all the rest of scripture, tells us we are the imago Dei, not the imago dog. We are made in the image of God, not the image of the animal. We are not defined by our cravings but by our creator. Ultimate meaning comes from our Lord, not our libido. We have objective identity, dignity and worth. Gods reality always trumps human emotions and passions; mine, yours, and the governments.

This is the good news of the Gospel. Christ, himself makes it clear that, on this issue, Ms. Paul is right. No one is just a mix of body parts and gender stereotypes. Women are made in the image of God, and that image cannot be manipulated, coopted or changed by a bunch of delusional sexual activists bent on denying reality and acting like dogs.

Why Are We All So Obsessed With Celebrity Plastic Surgery? – HuffPost UK

Youre on TikTok scrolling, as you do and have been for the past 45 minutes. Youve watched a dozen make-up tutorials, Love Island recaps and videos of cats doing very cat things when you stumble on a video of Kendall Jenner.

But its not a clip from Keeping Up With The Kardashians or even Kendall modelling on a runway. Its of her face being analysed by a surgeon. You watch as a doctor tells you what surgery she has or hasnt had. Theyll tell you that shes got fillers in her lips, botox and a secret rhinoplasty (aka nose job).

Click through to the doctors page and suddenly youve entered a world of celebrity plastic surgery videos. Theres been a surge of these videos emerging on my for you page in the past couple of months. The hashtag #plasticsurgery have 13.3 billion views, while the hashtag #celebrityface has 1.6 billion views.

When I typed, Has Kendall Jenner had plastic surgery? into my search bar, hundreds of videos came up. Some from cosmetic professionals, others from regular users, all picking apart her face. Its no surprise these videos mainly analyse women. Celebs such as Ariana Grande, Selena Gomez, Khloe Kardashian and Zendaya are also being facially examined on the daily.

Even teenagers like Stranger Things Millie Bobby Brown, 18, are scrutinised on TikTok though one in-depth blog about her face allows the changes that people are nitpicking on might be just her growing up and better makeup.

So, why are these clips so popular? It could be that celebrities dont often disclose what work theyve had done leaving their fans to guesswork.

When supermodel Bella Hadid, 25, shared that she had got a nose job at 14, few were surprised. Wed seen the before and after pictures, knew she had the money to pay for surgery, so people werent shocked to hear it confirmed.

However, speculation around a celebs face is often just that: speculation.

Earlier this year, the pop star Doja Cat publicly called out YouTuber Lorry Hillmade for making a video claiming the singer had got a nose job. Hillmade has plastic surgery herself and uses her page to dissect celebritiess faces to spot if theyve also had work done.

But Doja Cat wasnt happy about it and went on Instagram Live to say so. Im upset because theres lies about me, the singer said.

Dr Tunc Tiryaki, a consultant plastic surgeon at the Cadogan Clinic in London, doesnt think the videos are the root of the issue. Instead, he points the finger at those in the public eye who arent honest about the work theyve had done.

Id say the problem is more with celebrities who get liposuction, for example, but claim to get these results with diets, he says. Or celebrities who have had a face lift but say they had a thread lift [which is] similar to a face-lift but less invasive and cheaper.

By doing this, he says, celebrities are creating a huge false expectation, one that can make their followers compare themselves to someone with much greater means whose face is the result of thousands of pounds worth of surgery rather than more affordable tweakments, good makeup or basic genetics.

Secondly, these videos undermine the accurate results of surgery, especially surgical interventions, he says. People are coming to me expecting huge results because a celebrity has lied about what procedure theyve had.

This is dangerous, Dr Tiryaki, says, especially when it comes to filler and botox, as there isnt an age restrictions on these non-surgical procedures, nor is the industry properly regulated.

The rate of complications of fillers are rocketing, he says. This is partially because its easy to do and fillers can be done not only by dermatologists and plastic surgeons but anybody.

Many of these videos are made my cosmetic doctors, but even a surgeon wont be able to tell you if a celeb has had work done unless the professional did it themselves, says Dr Tiryaki, who warns against trusting these opinions. I think deep research is needed as its hard to fight against false information, he says.

And while there is an audience for these videos, people will continue churning them out. So, why do the general public enjoy these videos so much?

Many comments under the line highlight the relief some people feel when they discover their favourite celebs has had a bit of filler. So Im not ugly, Im just poor, one user writes. Given the online world and its facade of perfection, perhaps these pages do serve a purpose by highlighting why we shouldnt be comparing ourselves to celebrities.

Federica Rosso, a clinical psychologist at the mental health organisation Therapethical, believes the content is popular, because it can make people feel better about themselves even if that effect is short-lived.

People might start thinking that perfection per se does not exist. Even if they see themselves as not perfect in the mirror, they realise that one attractive celebrity did [the same] at some point and went through surgery, she says.

It creates an escape option from their awful feeling that is, in fact, a coping mechanism.

However, it can also encourage people to get work done that may not be in the best interests of their health or their finances. The problem with these videos is that theyre reinforcing a narrative that says we could achieve similar results if only we were willing to go under the knife ourselves. says Rosso.

We might start to wonder if our faces are ugly or unattractive or if there are parts of our bodies that need fixing. This can lead us down a dangerous path of body dysmorphia and eating disorders, both of which lead people down an unhealthy path toward self-harm and suicide.

These videos can be triggering for the celebrities they feature, too and, whether or not they have had any surgery, make them very self-critical of their looks.

Seeing themselves on these types of sites can be like a slap in the face, says Rosso. Theyre constantly reminded of their flaws and failures, even if theyre not real.

And this is nothing new. Dirty Dancing star Jennifer Grey, 62, has spoken openly about the nose job she had in the wake of that movies success, which not only ruined her career, but became the dominant narrative of her life.

Meanwhile, in 2016, Rene Zellwegger responded to claims shed had surgery on her eyes with an open letter in HuffPost, headlined We Can Do Better.

Its no secret a womans worth has historically been measured by her appearance, Zellwegger, now 52, wrote. The double standard used to diminish our contributions remains, and is perpetuated by the negative conversation which enters our consciousness every day as snark entertainment.

She added: The resulting message is problematic for younger generations and impressionable minds, and undoubtably triggers myriad subsequent issues regarding conformity, prejudice, equality, self acceptance, bullying and health.

So, should we continue to click on these videos? The answer surely lies in being honest with yourself about why youre watching them. Yes, they can serve as a reminder that the tweaked and filtered faces we see online every day arent real.

However, lets all remember that the people behind them very much are.

Can Biobanking Save the World’s Rarest Wildlife? – MeatEater

Late last year, the U.S. Fish and Wildlife Service proposed removing 23 species from the Endangered Species List, but not for the reason you might hope.

All 23 species of birds, fish, and mussels have gone extinct, according to the USFWS, and are no longer eligible for listing under the Endangered Species Act.

Many of these species have been on the decline for decades. Some, like the Hawaiian Kauai nukupuu bird, havent been spotted since the 19th century. As the USFWS explained in its press release, ESA protections came too late to conserve habitat and protect these animals from invasive species and disease.

Some believe biobanking can save other animal populations from the same fate. Wooly mammoths probably arent on that list, but biobanking advocates say animal cells frozen in cold storage could be used to beef up the genetic diversity of captive populations and restore some species from the brink of extinction.

What is Biobanking?

Biobanking refers to the collection and storage of biological materials. There are many kinds of biobanks designed for different purposes, but conservationists are particularly interested in biobanks like San Diego Zoos Frozen Zoo.

As its name suggests, the Frozen Zoo stores living animal cells by super-freezing (the technical term) those cells at -196 degrees Celsius. Virtually all cell activity stops at this temperature, which allows scientists to store samples until they want to use them. These cells can come from anywhere on an animals body and often include reproductive cells like sperm and eggs.

The Frozen Zoo launched in 1975 and has since been able to store 1,100 species of vertebrate animals and cells from over 10,000 individual animals, according to Dr. Oliver Ryder. Dr. Ryder is the Frozen Zoos Director of Conservation Genetics, and he spoke to MeatEater about the importance of banking the cells of endangered animals.

Were seeing species decline in numbers, populations disappear from within their range due to habitat loss and fragmentation. For some species, more of their gene pool is in these freezers than is in the wild, Dr. Ryder told MeatEater.

Most of the Frozen Zoos samples come from animals at the San Diego Zoo, where biologists can collect cells during an animals regular checkups or postmortem examinations. The Frozen Zoo tries to bank a diverse collection of animals, but time and space constraints force them to select vulnerable species over less vulnerable ones.

The Frozen Zoo isnt alone. Among other biobanks related to animal conservation, the Rare Breed Survival Trust in the United Kingdom houses a gene bank of native livestock breeds, the National Oceanic and Atmospheric Administration houses the National Marine Mammal Tissue Bank (NMMTB), and Japans National BioResource Project houses animal and plant materials to advance scientific research.

Current Successes

Freezing biological specimens might sound like something out of Mel Gibsons 1992 movie, Forever Young, but the reality is less science fiction and more science class.

Frozen zoos can help researchers investigate parentage, genetic lineage, evolutionary history, and disease susceptibility of individuals or species. However, a biobanks greatest conservation potential is its ability to beef up the genetic diversity of captive breeding programs.

Captive breeding programs are expensive, but the biggest hurdle is maintaining healthy genetic diversity. This issue is especially concerning for species that do not exist in the wild. A small captive population will eventually die out without new individuals to introduce genetic diversity.

This almost happened to the black-footed ferret. The black-footed ferret is the only ferret native to North America, but the population was so small by the late 20th century that the species was thought to be extinct.

Conservationists found the last remaining wild population in 1981, but only seven of those 18 ferrets produced kits. The captive breeding program for the black-footed ferret has successfully produced thousands of ferrets, but the entire population descended from those seven individuals.

Fortunately, biologists in the 1980s preserved a tissue sample from one of the non-breeding female ferrets and sent that sample to the San Diego Frozen Zoo. Those cells were preserved until 2020, when a group of scientists created a ferret embryo from that tissue, which was born later that year.

This cloned ferret, dubbed Elizabeth Ann, is not related to any black-footed ferret currently in existence and could provide some much-needed genetic variation to the population. She is the first clone of a native endangered species in North America.

It was like discovering a new ferret, Dr. Ryder said.

Its unclear whether Elizabeth Ann is necessary to the black-footed ferrets continued success. The Smithsonians National Zoo & Conservation Biology Institute has released thousands of black-footed ferrets in partnership with the USFWS, and they dont report a lack of genetic diversity as one of the populations primary threats.

But in a press release announcing Elizabeth Anns birth, the USFWS pointed out that the ferrets must overcome unique genetic challenges and could eventually become more susceptible to disease, infertility, and genetic abnormalities.

In any case, if Elizabeth Ann proves to be fertile (researchers will know later this year), the project will provide powerful proof of concept for how biobanking can save threatened species.

Researchers at the Australian Frozen Zoo are also offering a less dramatic way biobanking could theoretically introduce genetic diversity into captive breeding populations. Biobanked sperm, researchers argue, can allow captive programs to operate with fewer animals while maintaining the diversity needed for a healthy population.

Using frozen zoos could provide a 25-fold increase in the number of species that could be conserved. This would be a staggering conservation achievement, and we think it can be done, said Dr. Simon Clulow of Macquarie University in Sydney.

Clulow and his colleagues published a paper in 2020 arguing that introducing biobanked frozen sperm to an Oregon spotted frog breeding program could significantly reduce the cost of the program. They suggest that backcrossingcrossing a hybrid with one of its parents or a creature genetically similar to its parentwith frozen sperm every generation would lead to much lower costs than with traditional captive breeding.

Reducing the cost of captive breeding programs will free up resources to conserve species other than the so-called charismatic megafauna that generate the most funding and attention.

Moral Hazard

Not all conservationists are quite as excited about using biobanked material in these ways. Dr. Stuart Pimm is the Doris Duke Professor of Conservation Ecology at Duke University, and he worries that de-extinction techniques (which are still largely theoretical) can give moral cover to people and organizations that want to destroy habitat.

If you think its OK to drive species to extinction because you think we can keep their DNA going, it creates an awful moral hazard, Dr. Pimm told MeatEater.

Resurrecting ancient species like the wooly mammoth gets a lot of play in the news (not to mention Hollywood), but when asked about mammoths, Dr. Ryder sounded skeptical. Both he and Dr. Pimm argued that mammoth resurrection isnt practical. Dr. Ryder noted that no viable mammoth DNA exists with which to make a clone, and Dr. Pimm wondered how scientists would reconstruct mammoth habitat and ecosystems.

But while Dr. Ryder is still interested in using genetic technology to save declining species, Dr. Pimm has personal experience that keeps him wary of anything that rhymes with de-extinction. When he testified before Congress in the mid-1990s about the reauthorization of the Endangered Species Act, members of Congress expressed unconcern with habitat destruction because endangered species could be resurrected a la Jurassic Park.

There are people who would like to push environmental destruction to the limit, so the moral hazard of de-extinction is a real danger, Pimm said.

Instead of using time and resources to pursue the kind of genetic strategies made possible by biobanks, Dr. Pimm would like to see conservationists focus on what works: habitat restoration, legislative protections, and public education.

The amount of time people are wasting on these de-extinctions, they could get off their arses and do something useful for conservation, he said. I think theyre doing a considerable amount of harm in giving people false solutions. Thats not how were going to save biodiversity.

When asked about Dr. Pimms moral hazard, Dr. Ryder agreed that its a legitimate concern and acknowledged that solutions like Elizabeth Ann are still highly experimental. We cant bank all our conservation efforts on their success, he said.

He took issue, however, with the contention that the two approaches represent a zero-sum game.

That argument would presume that focusing effort on banking cells would detract from efforts to save species. All the evidence is to the contrary. The effort to save species is as strong as ever and is supported by international treaties and national legislation and regulation, he pointed out.

For his part, Dr. Pimm was careful to distinguish between de-extinction technologies and biobanking more generally. He does not support the former, but the latter he described as essential to conservation efforts. Storing genetic material is not a problem; what matters is how we use it.

Moving Forward

Both scientists agreed that conserving threatened and endangered species requires a collaborative, multi-pronged approach. Dr. Ryder stressed that habitat conservation should always be a top priority, and Dr. Pimm said he could support promoting genetic diversity via biobanked material if those techniques proved to be effective.

Ultimately, Dr. Ryder believes conservationists should pursue the kinds of solutions hes spearheading at the Frozen Zoo in the hopes that they wont have to use them.

My hope is that we wont need to do these kinds of things because we wont have species that are so depleted in their genetic variation or on the brink of extinction that we have to evoke these heroics, he said.

But given that were seeing a number of species in decline, it would be prudent, thoughtful, and helpful to bank cells now so that we have that option in the future, he continued. I would like to see a greatly expanded effort to do banking so that we wouldnt need to be looking at a future where were inevitably seeing the genetic diversity of wild species erode.

Adrenal Fatigue and Narcolepsy: Comparing the Conditions and Theories – Healthline

Narcolepsy is a neurological condition that affects your bodys sleeping and waking cycles.

Its estimated that between 135,000 and 200,000 people in the United States have narcolepsy. If you have it, youll often feel very tired during the day and may also unexpectedly fall asleep in the middle of activities. Its also possible to experience cataplexy, which is when muscle weakness comes on suddenly.

Adrenal insufficiency is a health condition where your adrenal glands dont make enough of certain hormones. This can lead to symptoms that are similar to those of narcolepsy, such as chronic fatigue and muscle weakness.

Another related term you may have heard of is adrenal fatigue, which is used to describe a mild type of adrenal insufficiency thats supposedly brought on by chronic stress. However, adrenal fatigue isnt a proven medical condition.

Below, well explore the ins and outs of narcolepsy, adrenal insufficiency, and adrenal fatigue. Keep reading to learn more.

Adrenal fatigue is a theory that chronic stress can impact the function of the adrenal glands. The adrenal glands are found above your kidneys and make hormones like cortisol, which is important for how you respond to stress.

Supporters of the theory of adrenal fatigue believe that the buildup of stress becomes too much for your adrenal glands. Due to this, they cannot produce enough cortisol to meet the bodys demands, causing symptoms like:

While some symptoms of adrenal fatigue are similar to those of narcolepsy, it really isnt possible to compare the two. This is because adrenal fatigue isnt recognized as a legitimate medical condition.

In a 2016 article, a group of endocrinologists reviewed 58 studies mentioning adrenal fatigue. Based on their review of the studies and how they were conducted, they could find no credible evidence that adrenal fatigue is an actual medical condition.

The reported symptoms of adrenal fatigue are general and could be caused by any actual health condition that needs to be treated. According to the Endocrine Society, these may include conditions like:

Adrenal insufficiency is a medical condition in which your adrenal glands dont make enough of the hormone cortisol and, in some cases, aldosterone. There are several types of adrenal insufficiency.

Some types have to do with decreased production of hormones in the brain. These hormones eventually promote cortisol production in the adrenal glands, so when theyre in short supply, cortisol levels are lower.

Some types of narcolepsy also have to do with decreased hormone production in the brain. In this case, its the hormone hypocretin, also called orexin, which regulates sleeping and waking.

Its also possible for people with narcolepsy to have other health conditions involving hormones, such as adrenal insufficiency and hypothyroidism.

Older research has also found that low levels of hypocretin in people with narcolepsy may impact other hormone pathways, such as those involved in adrenal insufficiency.

Lastly, theres overlap in the symptoms of adrenal insufficiency and narcolepsy, such as excessive tiredness or fatigue and muscle weakness.

However, there are many important differences between adrenal insufficiency and narcolepsy as well. Lets go over the different aspects these two conditions now.

The symptoms of adrenal insufficiency typically come on slowly and can include things like:

The symptoms of narcolepsy can include:

There are different types of adrenal insufficiency and each type as its own cause:

Similar to adrenal sufficiency, there are different types of narcolepsy. What causes each type is a little different.

People with type 1 narcolepsy, or narcolepsy with cataplexy, almost always have low levels of a hormone called hypocretin in the brain. This hormone is involved in regulating aspects of sleeping and waking.

Those with type 2 narcolepsy, or narcolepsy without cataplexy, have normal levels of hypocretin. The cause of this type of narcolepsy remains unclear.

Factors that may contribute to the development of narcolepsy in general include:

The risk factors for adrenal insufficiency can include:

You may be at an increased risk for narcolepsy if someone in your family has it. About 10% of people with type 1 narcolepsy have a close relative who reports similar symptoms.

An adrenal crisis is the most serious complication of adrenal insufficiency and is life threatening. It can happen when your body needs more cortisol than it can make, typically in response to intense physical stress caused by things like:

Its also possible for adrenal insufficiency to lead to electrolyte imbalances like too little sodium or too much potassium.

The nature of its symptoms can mean that narcolepsy can have a large impact on a persons quality of life. People with narcolepsy can experience significant disruptions in their daily life, including:

Additionally, sleep attacks and cataplexy can happen suddenly. This can be dangerous if youre driving or working in a job that involves operating heavy machinery.

In addition to taking your medical history and doing a physical exam, a doctor can use the following tests to diagnose adrenal insufficiency:

After taking your medical history, performing a physical exam, and evaluating your sleep log, your doctor can use the following tests to help diagnose narcolepsy:

The treatment for adrenal insufficiency involves replacement of the hormone cortisol. This can be done through drugs like hydrocortisone, dexamethasone, or prednisone.

Taking a drug called fludrocortisone can help maintain electrolyte balance in people who also dont make enough aldosterone.

There isnt a cure for narcolepsy. Instead, symptoms are managed using a combination of medications and lifestyle changes.

Medications for narcolepsy can include:

Lifestyle changes are also important, including setting up a regular sleep schedule, taking shorter naps during the day, and relaxing before bedtime.

If you have any of the following symptoms, its a good idea to see a doctor:

A doctor can evaluate your symptoms and test to see what may be causing them. After a diagnosis is made, they can develop a treatment plan that can help you to manage your condition.

Narcolepsy is a neurological condition affecting sleeping and waking. It causes symptoms like excessive daytime sleepiness, sleep attacks, and sudden instances of muscle weakness.

While some narcolepsy symptoms like excessive tiredness and muscle weakness overlap with adrenal insufficiency, the two conditions have many other differences in symptoms, causes, diagnosis, and treatment.

You may have also heard narcolepsy symptoms be compared to those associated with something called adrenal fatigue. However, adrenal fatigue is not recognized as an actual medical condition at this time.

Regardless, see a doctor if you have excessive tiredness, muscle weakness, or disrupted sleep that significantly interferes with your daily life. Its possible that your symptoms are due to a medical condition that needs to be treated.

Heres what the James Webb Space Telescope has seen in just a week of looking

A quintet of galaxies. A nursery of infant stars. A weather report for an exoplanet. And a preview of our own suns demise.

After years of delays, a 930,000-mile trip into space and months of speculation over whatthe James Webb Space Telelescopes first pictures might reveal, NASA on Tuesday released the first complete set of images captured by its $10-billion observatory.

They show stars in their infancy and in their final gasps, along with sweeping views of the cosmos and the majestic objects in it.

Every dot of light we see here is an individual star, not unlike our sun. And many of these likely also have planets, NASA astrophysicistAmber Straughnsaid while introducing an image of theCarina Nebula, a multihued landscape of gas and nascent stars.

It just reminds me that our sun and our planets and, ultimately, us were formed out of the same kind of stuff that we see here, she said. We humans really are connected to the universe. Were made of the same stuff in this beautiful landscape.

Webb Images of Jupiter and More Now Available In Commissioning Data

On the heels of Tuesdays release of thefirst imagesfrom NASAs James Webb Space Telescope, data from the telescopes commissioning period isnow being released on the Space Telescope Science Institutes Mikulski Archive for Space Telescopes. The data includes images of Jupiter and images and spectra of several asteroids, captured to test the telescopes instruments before science operations officially began July 12. The data demonstrates Webbs to track solar system targets and produce images and spectra with unprecedented detail.

Fans of Jupiter will recognize some familiar features of our solar systems enormous planet in these images seen through Webbs infrared gaze. A view from the NIRCam instruments short-wavelength filter shows distinct bands that encircle the planet as well as the Great Red Spot, a storm big enough to swallow the Earth. The iconic spot appears white in this image because of the way Webbs infrared image was processed.

In ominous sign for global warming, feedback loop may be accelerating methane emissions

If carbon dioxide is an oven steadily roasting our planet, methane is a blast from the broiler: a more potent but shorter lived greenhouse gas thats responsible forroughly one-thirdof the 1.2C of warming since preindustrial times. Atmospheric methane levels have risen nearly 7% since 2006, and the past 2 years saw thebiggest jumps yet, even though the pandemic slowed oil and gas production, presumably reducing methane leaks. Now, researchers are homing in on the source of the mysterious surge. Two new preprints trace it to microbes in tropical wetlands. Ominously, climate change itself might be fueling the trend by driving increased rain over the regions.

If so, the wetlands emissions could end up being a runaway process beyond human control, although the magnitude of the feedback loop is uncertain. We will have handed over a bit more control of Earths climate to microorganisms, says Paul Palmer, an atmospheric chemist at the University of Edinburgh and co-author of one of the studies,posted late last monthfor review atAtmospheric Chemistry and Physics.

Study: Climate impacts to disproportionately hurt tropical fishers, farmers

Coastal communities in the tropics that rely heavily on both agriculture and fisheries are most vulnerable to the losses caused by high global carbon emissions, a new study says.

It looked at coastal communities in five countries within the Indo-Pacific region and found that most may face significant losses of agricultural and fisheries products two key food sources simultaneously in the event of the worst-case impacts of climate change. These potential losses may be coupled with other drivers of change, such as overfishing or soil erosion, which have already caused a decline in productivity, according to thestudypublished July 5 in the journalNature Communications. When looked at separately, the potential losses for the fisheries sector would be greater than for agriculture, the research showed.

But if carbon emissions can be effectively managed to a minimum, the studys authors said, fewer communities would experience losses in both the agriculture and fisheries sectors.

Pioneering climate change research reveals long-term global carbon cycle impacts

A new study in Nature Geoscience, co-authored byDr Heather Ford , uses a unique research model to illustrate how past geologic periods can help us understand future climate changes. []

In this new paper, Dr Ford used geologic data and a climate model of a time about three million years ago known as the mid-Pliocene warm period, which is often used as an analogue for future climate change, because global temperatures then were around 2.3C warmer than today but CO2 levels were similar.

Whats unique about this study is the climate model was run for 2000 years, allowing conditions in the deep ocean to balance naturally over time, and enabling much deeper insight. Dr Ford explained: Running global climate models for thousands of years is computationally expensive, but critical in thinking about long-term impacts of carbon cycling and climate change.

As extreme weather events occur more frequently something that climate scientists say is inevitable so, too, will violence towards women and people from gender minorities. Thats the conclusion of a review examining events in the aftermath of floods, droughts, cyclones and heatwaves, among other weather disasters, over the past two decades.

The review found that extreme weather events often catalyse episodes of gender-based violence particularly physical, sexual and domestic abuse. It is the most comprehensive and timely analysis of gender-based violence related to extreme weather and climate events that are expected to increase under anthropogenic climate change, according to lead author Kim van Daalen, who studies global public health at the University of Cambridge, UK.

Its Getting Harder for Forests to Recover from Disasters

Forests around the world are losing their resilience and becoming more vulnerable to disturbances as the planet warms. Thats especially true for ecosystems in tropical, temperate and dry parts of the world, according to a new study.

When a forest loses resilience, it means its gradually losing its ability to bounce back after fires, droughts, logging and other disruptive events, said thestudy, published on July 13 inNature. Past a certain point, some forests may approach a kind of tipping point a threshold that launches them into a rapid decline.

And beyond that, some studies suggest, a forest may not be able to fully recover at all. It may instead transform into some other ecosystem entirely, like a grassland or savanna.

Study provides new clues to killer frog disease

A new study aiming to unlock the secrets of a disease devastating frog populations has turned up some unexpected results, which may change how scientists combat the outbreak.James Cook University biologist Dr Donald McKnight said the disease chytridiomycosis has caused declines or extinctions in over 500 species of amphibians worldwide.

But not all amphibian species are susceptible to chytridiomycosis, and some species and populations that underwent initial declines are surviving or increasing, despite the continued presence of the pathogen, said Dr McKnight. []

The reasons for these differences among species and populations are not entirely clear, but variations in microbiomes - the bacteria, fungi, and other microorganisms on the frogs - may play a key role, said Dr McKnight.

Machine learning identifies crater that ejected famous Martian rock

New Curtin-led research has pinpointed the exact home of the oldest and most famous Martian meteorite for the first time ever, offering critical geological clues about the earliest origins of Mars.

Using a multidisciplinary approach involving a machine learning algorithm, the new research published today inNature Communications identified the particular crater on Mars that ejected the so-called Black Beauty meteorite, weighing 320 grams, and paired stones, which were first reported as being found in northern Africa in 2011.

The researchers have named the specific Mars crater after the Pilbara city of Karratha, located more than 1500km north of Perth in Western Australia, which is home to one of the oldest terrestrial rocks.

Zombie fly fungus lures healthy male flies to mate with female corpses

Entomophthora muscaeis a widespread, pathogenic fungus that survives by infecting common houseflies with deadly spores. Now, research shows that the fungus has a unique tactic to ensure for its survival. The fungus 'bewitches' male houseflies and drives them to necrophilia with the fungal-infected corpses of dead females.

After having infected a female fly with its spores, the fungus spreads until its host has slowly been consumed alive from within. After roughly six days, the fungus takes over the behavior of the female fly and forces it to the highest point, whether upon vegetation or a wall, where the fly then dies. When the fungus has killed the zombie female, it begins to release chemical signals known as sesquiterpenes.

"The chemical signals act as pheromones that bewitch male flies and cause an incredible urge for them to mate with lifeless female carcasses," explains Henrik H. De Fine Licht, an associate professor at the University of Copenhagens Department of Environment and Plant Sciences and one of the studys authors.

Social support found to reduce stress levels in orphaned wild elephants

A team of researchers from Colorado State University, the Smithsonian Conservative Biology Institute and the Save the Elephants program in Kenya reports that social support by members of elephant herds in African savanna elephants reduces stress levels of orphaned youngsters. In their paper published in the journalCommunications Biology, the group describes their study of stress levels in orphaned wild elephants and their ability to rebound from a great loss.

Over the past several decades, African savanna elephants, the largest land animals in the world, have seen population declines due to increases in both poaching and droughta situation that has led to many elephants being orphaned. Because of the long maturation process (it takes 20 years for the elephants to reach their full size), the number of orphans has increased overall. Also, elephantcalvesare highly dependent on their mothers for the first decade of their lives. In this new effort, the researchers studied the stress levels of orphans as they adapted to sudden changes in their care.

To learn more aboutorphanstress levels, the researchers followed several herds for over a year, watching carefully when they defecated. They collected the samples and tested them for glucocorticoid metabolite (GCM) levelsa relatively easy way to measurestress levelsin mammals.

A woodpecker's brain takes a big hit with every peck: study

The brain of a woodpecker experiences a seemingly catastrophic impact every time beak meets wood.

"When you see these birds in action, hitting their head against a tree quite violently, then as humans we start wondering how does this bird avoid getting headaches or brain damage," saysSam Van Wassenbergh, a researcher at the University of Antwerp in Belgium.

In the past, scientists havesuggestedthe bird's brain is protected from the impacts, perhaps bya skull that acts as a cushion, or a beak that absorbs some of the force, or a tongue that wraps around the brain.But Van Wassenberg wasn't convinced.

"Nobody has ever explained it very well, in my opinion," he says.

Difficult and costly. Snake dams should be breached, says Biden administration report

Breaching one or more of the lower Snake River dams in Eastern Washington is called for in a National Oceanic and Atmospheric Administration draft report released Tuesday.

The draft report looks at the state of the science on restoring salmon and steelhead populations in the Columbia River Basin and the large scale actions needed to make progress toward healthy and harvestable fish stocks.

It has become overwhelmingly clear that business as usual will not restore the health and abundance of Pacific Northwest salmon, said Brenda Mallory, chairwoman of the White House Council on Environmental Quality, at a news media briefing Monday afternoon. []

The NOAA draft report, Rebuilding Interior Columbia Basin Salmon and Steelhead, said the science calls for acting, and acting now.

Inaction will result in the catastrophic loss of the majority of Columbia River Basin salmon and steelhead stocks, the draft report said.

Knots in the resonator: elegant math in humble physics

At the heart of every resonator be it a cello, a gravitational wave detector, or the antenna in your cell phone there is a beautiful bit of mathematics that has been heretofore unacknowledged. Yale physicists Jack Harris and Nicholas Read know this because they started finding knots in their data.

In a new study in the journal Nature, Harris, Read, and their co-authors describe a previously unknown characteristic of resonators. A resonator is any object that vibrates only at a specific set of frequencies. They are ubiquitous in sensors, electronics, musical instruments, and other devices, where they are used to produce, amplify, or detect vibrations at specific frequencies.

The new characteristic the Yale team found results from equations that any high school algebra student would recognize, but which physicists had not appreciated as a basic principle of resonators.

Bat Virus Studies Raise Questions About Laboratory Tinkering

In mid-2020, a team of scientistscatching bats in Laotian cavesdiscovered coronaviruses that were strikingly similar to the one that had begun wreaking havoc around the world.

In the months since, some of those researchers have been studying one of these mysterious bat viruses in a high-security laboratory in Paris, hoping to discover clues about how its cousin, SARS-CoV-2, went on to become a global threat that has killed anestimated 15 million people.

Their work has been scientifically fruitful. Last year, the scientists discovered thatthe bat virus was capable of latching onto human cells, at least in Petri dishes. Last month, the teamreportedmore reassuring news: that the virus is not particularly harmful to lab animals. The finding suggests that SARS-CoV-2 evolved its abilities to spread quickly and cause deadly disease only after the two lineages branched apart on the viral evolutionary tree.

Mysterious glow of a milky sea caught on camera for first time

Waking at 10pm, a sailor looked out from the deck of the superyacht Ganesha to see that the ocean had turned white. There is no moon, the sea is apparently full of plankton, but the bow wave is black. It gives the impression of sailing on snow, they wrote.

For centuries, mariners have described navigating unearthly night-time waters, lit up by a mysterious glow, but such milky seas have long eluded scientific inquiry owing to their remote, transient and infrequent nature.

Id say theres only a handful of people currently alive who have seen one. Theyre just not very common maybe up to one or two per year globally and theyre not typically close to shore, so you have to be in the right place at the right time, said Steven Miller, a professor of atmospheric science at Colorado State University in Fort Collins.

An Army of Turtles Is Doing Cyclone Reconnaissance

Even with good data, its hard to predict tropical cyclones, which often appear with little warning and wander drunkenly around the worlds oceans. But five years ago, Olivier Bousquet, now the research director for Frances Ministry of Ecology, Sustainable Development and Energy, was tasked with forecasting storms strengths and paths in the cyclone-infested southwest Indian Ocean. The need for better predictions was great. On average, the area gets nine or 10 cyclones a year, and the storms are getting stronger. Tropical Cyclone Idai, in 2019, killed more than 1,000 people in Mozambique, Zimbabwe, and Malawi and 2014s Gafilo killed 363 in Madagascar.

Unlike in some other parts of the oceansuch as the North Atlantic, where the U.S. National Oceanic and Atmospheric Administration flies weather dronesBousquet had almost no data to work with. Sure, there are satellites that spy on the oceans surface, but those are biased around coastlines and blind in clouds, which storms have in spades. Just a handful of floating oceanographic buoys collected temperature, depth, and salinity information where Bousquet needed it. So he set out to find a new source of data.

For the past few decades, scientists have been using satellite-tagged animals to collect ocean data. For instance, in the Southern Ocean off Antarcticaa famously hostile area for humans and shipssouthern elephant seals have gathered much of the basic data we have on the waters temperature and salinity.

Researchers harness algae to grow construction cement

The massive worldwide pouring of concrete as developers densify cities could be transformed, eliminating heat-trapping pollution into the atmosphere, by switching to a new kind of cement created in Colorado cement that is grown by harnessing tiny sea organisms.Urban concrete jungles also would look less gray because the new cement is lighter in color and more reflective.

The U.S. Department of Energy this month embraced University of Colorado research that developed this cement, investing $3.2 million for scaling up cultivation of an algae species called coccolithophores. CUs innovation appealed to the DOEs Advanced Research Projects Agency because cement production causes 7% of the global heat-trapping pollution that accelerates climate warming. Thats a significant share, exceeding emissions from airplane travel.

This is a carbon dioxide removal project, said CU Boulder materials scientist Wil Srubar, leader of the work and director of CUs Living Materials Laboratory, who got got the idea while snorkeling in Thailand on his honeymoon in 2017. He saw magnificent natural limestone structures in coral reefs and wondered whether humans could replicate natural processes to make enough limestone for cement instead of excavating limestone from quarries.

Y chromosome loss through aging can lead to an increased risk of heart failure and death from cardiovascular disease, new research finds

The Y chromosome can be lost through the process of aging, and this can lead to an increased risk of heart failure and cardiovascular disease, according to a recent study my colleaguesand Ipublished in the journalScience.

While most women have two X chromosomes, most men have one X and one Y. And many people with Y chromosomes start to lose them in a fraction of the cells in their body as they age.

While loss of the Y chromosome wasfirst observed in 1963, it was notuntil 2014that researchers found an association between loss of the Y chromosome and shorter life span. Y chromosome loss has since been linked to a number ofage-related diseases, such as cancer and Alzheimers disease. However, it has been unknown whether this loss is just another benign indicator of aging, like gray hair or skin wrinkles, or whether it has a direct role in promoting disease. []

We found that while loss of the Y chromosome did not have immediate effects on the young mice, they ended up aging poorly, dying at an earlier age than mice that still had Y chromosomes. They also had more buildup of scar tissue in the heart, a condition calledfibrosis, as well as a stronger decline in heart function after induced heart failure. Treating the mice with a drug that blocks heart scarring, however, was able to restore lost heart function.

Genetic testing could help match people with the right antidepressant, new VA study finds

Understanding patient genetics could help to minimize the trial-and-error approach to prescribing antidepressants, a national study led by researchers at the Crescenz VA Medical Center in Philadelphia has found.

Finding the right antidepressant can take time. Its not uncommon for patients to try a few before finding an effective medication without too many side effects. Each round can mean losing weeks while waiting for the medication to start working, a frustrating reality for patients who seek relief and prescribers who often have little to guide them toward the optimal prescription.

Often with medications you might start with one, a patient might have side effects for that or it might not work, said David Oslin, a psychiatrist at the Philadelphia-based VA Medical Center. You end up with a second or third trial before finding something thats effective.

The oldest, brightest black holes in the universe were born from violent gas attacks, new study suggests

Twinkling like cosmic lighthouses on a shore 13 billion light-years from Earth, quasars are some of the oldest, brightest relics of the early universe that astronomers can detect today.

Short for "quasi-stellar radio sources," quasars are gargantuanblack holesthat glow as brightly as galaxies and are millions to billions of times as massive asEarth's sun. Today, quasars exist at the centers of many large galaxies. But thanks to their exceptional luminosity, quasars have been tracked far acrossspace-time, with roughly 200 of them identified as forming within the first billion years of our universe's history.

How could such massive objects form so early, when galaxies were sparse and large stars were exceptionally rare? The question has bedeviled researchers for more than two decades, since the first quasars were identified and now, a new study published July 6 in the journalNature

Researchers Have Found The First Example of Another Mammal 'Farming' Its Food

It was thought that humans were unique amongst mammals when it came to farming but depending on how strict we are with definitions, it turns out we might not be alone when comes to tending the land to grow food.

Scientists have discovered thatpocket gophers(Geomys pinetis) also practice a form of agriculture.

Measurements on a field containing burrows built by the little critters suggest they don't just harvest the longleaf pine roots that grow into their homes they cultivate them. []

"Southeastern pocket gophers are the first non-human mammalian farmers,"says biologist Francis Putz, from the University of Florida. "Farming is known among species of ants, beetles, and termites, but not other mammals."

Geologists reveal trends in mineral diversity

By classifying minerals by how they were made, scientists could better study the complex chemistry on other worlds.

Geology reference texts define mineral species based on chemical composition and crystal structure. But mineral samples collected in the field often contain trace elements and structural defects that distinguish most specimens from a textbook example. If youre interested in comparing Earth with other planets, both within our solar system and beyond, then you really need to think beyond those very simple, idealized structures, saysRobert Hazen, a mineralogist and astrobiologist at the Carnegie Institution for Science. So Hazen and his colleagues devised a new way to categorize minerals using the imperfections that tell stories about each minerals geologic past.

Because minerals acquire defects as they form, the isotopic ratios and foreign inclusions trapped within their crystal lattices can help researchers understand the context in which they were made. After combing the literature, Hazen and his team identified approximately 60 processes, such as lightning and oxidation events, that contribute to the formation of the more than 5,000 minerals known on Earth.

If Youre Owned by a Cat, Scientists Want to Hear From You

Scientists in California are asking for U.S. volunteers who live with cats to participate in a new research project. The study will survey owners about their pets behaviours and their knowledge of training methods. The teams larger goal is to help cats especially kittens and humans better form healthy relationships with one another.

The work is being conducted by scientists from the Animal Welfare Epidemiology Lab at the University of California Davis. Last fall, the teamrecruitedvolunteers who owned exactly two cats to look at cat videos on the internet, as part of a project to study how well owners could read feline body language. They were especially interested in knowing whether owners could tell when cats were about to lash out at their furry roommates.

People considering suicide might show signs early on. Here’s what to watch for – CNN

Researchers still haven't nailed down how to better predict who's at risk for attempting suicide, and whether or when vulnerable people will do it, said Justin Baker, clinical director of The Suicide and Trauma Reduction Initiative for Veterans at The Ohio State University Wexner Medical Center.

"That is extremely, extremely difficult," he said. "You can look back in time, when someone's made an attempt or has died, and go, 'Oh, look at all these things that were going on in their life.' The difficulty is that a lot of people handle or experience those types of stressors as well but never go on to (attempt suicide)."

Additionally, there isn't always a long timeframe wherein someone is considering suicide and showing signs -- and there can be as little as 5 to 15 minutes between someone deciding to attempt suicide and doing it, Baker added.

"What we collectively understand is it's an emotional dysregulation and cognitive error that occurs," Baker said. "They can't fix the situation, or they can't think their way through the situation, so suicide becomes a viable option as a way to manage the pain that they're in. So they may take action on it in that really short, brief window."

But there are some situations wherein a person who is suicidal and planning for a longer period of time will show behavioral changes, Baker added.

"If you're noticing that kind of stuff, obviously that's someone who is really close to being imminent risk -- someone who's really close to making that decision to end their life," he said. "But I would argue most people don't get that kind of warning."

Here are some of the most common behavioral, verbal and emotional signs and risk factors you should pay attention to, according to experts.

Behaviors to watch for

Some people might seem like their usual selves in the weeks or days leading up to a suicide attempt, while others might show behavioral changes that don't track with what you know about them, said Michael Roeske, a clinical psychologist and senior director of the Newport Healthcare Center for Research & Innovation.

Other potential behavioral red flags include giving away cherished belongings, sleeping too much or too little, withdrawing or isolating oneself, showing rage or desire to enact revenge, and acting anxious or agitated, according to Roeske, Baker and SAMHSA. Getting really intoxicated one night or driving recklessly could also be signs to watch out for, Roeske said.

Such behavior might be them "testing themselves to see if they can actually do it," Baker said. "A lot of times people need to kind of work up to that actual making an attempt because it's a biologic thing you have to go against, your own survival."

Concerning comments

Talking about wanting to die -- by suicide or otherwise -- is another warning sign that should always be taken seriously, Roeske said. Such comments are sometimes just expressions of discomfort, pain, boredom or desire for closeness rather than a reflection of actually wanting to die, but that doesn't mean you don't monitor the person who's making them, he added.

Some people might say they feel like they have no reason to live. "If someone is struggling to come up with a reason for living, that's a much higher-risk person than someone who's even able to identify one (reason)," Baker said.

Others talk about feeling like a burden on those close to them, Roeske said, or like they don't belong anywhere or with anyone. Such comments might include "You don't need me for this anymore" or "I feel like it'd be better if I just wasn't here." Teenagers considering suicide might not want their guardians to use their money for college, he added.

Mood and other risk factors

What to do

If any of these signs resonate with you, seek professional help and talk with someone you can trust and feel supported by, Baker said. Psychotherapy and certain psychiatric medications, such as antidepressants, can help, Roeske said.

If a loved one is showing signs they might be at risk of suicide, "it's not really your job to be able to predict the future," Baker said. But you can be supportive and intentional about asking them what's going on, Roeske and Baker said.

"You're not going to cause someone to be suicidal by asking directly about suicide," Baker said. "The worst they're going to say is 'no' and not get offended. If they are, still ask them. I'd rather have someone offended at me than dead."

When checking on someone, use what experts call a narrative, person-centered approach, Baker recommended. That might look like an open-ended question: "Hey, I've noticed life's gotten overwhelming these past couple days. Do you want to tell me about it?"

As the person responds, you can, to some extent, listen, express appreciation for them sharing their story and offer to help figure it out together, without offering advice on how to handle it, Baker said. But if your loved one seems more at risk or in the process of attempting suicide, "you no longer have time or the luxury to get their opinion," he added. Get medical care or call 911.

When Roeske first started working as a clinician, he had a young female patient who was a very accomplished equestrian, went to a prestigious school and had a lot of family resources, he said -- but she had been chronically suicidal for 10 to 15 years, since she was a teenager.

"Every time she would go to her mom and tell her that, her mom would (say things like) 'Oh, you're so beautiful. Look at how you are with the horses,'" Roeske said. "And (the patient) said, 'What it felt like was Mom was afraid of what I was saying and needed to distance herself from it.'

She said that therapists would do the same thing -- you know, 'create a positive gratitude list or correct your cognitive distortions.' Finally, there was a psychiatrist that looked at her as she said, 'I think I'm going to kill myself.' And the psychiatrist said, 'I think you might, too.' And she said it was the first time someone was willing to be in there with her."

When talking with someone who's suicidal, you might want to tell them all the wonderful reasons why they should stay alive, Roeske said -- but that can actually make them feel more lonely.

Unfortunately, "we are no better able to predict who will die by suicide than who will be in a car accident," Baker said. "This does not help to alleviate the grief or pain for those who have lost loved ones to suicide, but hopefully it helps remove some of the guilt and responsibility."

CNN's Jacqueline Howard contributed to this story.

PROMISING STEM CELL THERAPY IN THE MANAGEMENT OF HIV & AIDS | BTT – Dove Medical Press

Introduction

Stem cells are highly specialized cell types with an impressive ability to self-renew, able to transform into one or even more specific cell types that play a significant role in the regulation and tissue healing process.17 To self-renew, a stem divides into two identical daughter stem cells and a progenitor cell and the embryonic and adult cells contain stem cells.1,2,8

Curing patients with serious medical conditions has been the focus of all disciplines of medical research for many years. Stem cell treatment has evolved into a highly exciting and progressed field of scientific research. Major advances have recently been introduced in fundamental and translational stem-cell-based treatment studies. As stem cell research progressed, many therapeutic options were investigated. The development of therapeutic procedures has sparked a great deal of interest.1,9 Humanity has known for many years that it is possible to regenerate lost tissue. Recently, the regenerative medicine research has taken hold, defying the tremendous scientific advances in the molecular biology sciences only. Technological advances provide limitless opportunities for transformational and potentially restorative therapies for many of humanitys most illnesses. A variety of human organs have successfully yielded stem cells. Besides this, the cell therapy is rapidly bringing good advancements in the healthcare system, intending to restore and possibly replace injured tissue, as well as organs, and ultimately restore the functional capacity of the body.2,10,11

The stem cells can be obtained from various sources of Adult (Adult body tissues), Embryonic (Embryos), Mesenchyma (Connective tissue or stroma), and Induced pluripotent stem [ips] cells (Skin cells or tissue-specific cells).3,68,1215

Due to various stem cells cellular characteristics, the therapeutic clinical possibilities of stem-cell-based treatment are considered promising. These cells can regrow and restore various types of body tissues, for this reason, they are recognized as precursor cells to all kinds of cells.15 The following are the distinguishing features: 1. Self-renewal- Divide without distinction to generate an infinite supply, 2. Multi-potency- One mature cell may distinguish more than one, 3. Pluripotency- Create all sorts of cells except for embryonic membrane cells, 4. Toti- potency- Produce various sorts of cells, including embryonic stem cells.1,2,6,7,16

Stem cells are essential human cells that really can self-renew and make a distinction into particular mature cell types.3,6 The different types of stem cells are embryonic, induced pluripotent, and adult kind of cell types. They all share the important feature of self-renewal, and the ability to discern themselves. It should be mentioned that, the stem cells are not homogeneous, but instead appear in a progressive order. Totipotent stem cells are the most basic and immature stem cells. The above cells can form a complete embryo and also extra-embryonic tissue. This one-of-a-kind efficiency is only present for a short period, starting with ovum development and completing whenever the embryo achieves the 4 to 8 cell phases. Having followed that, cells that divide until they approach the blastocyst, about which point they end up losing their totipotency and acquire a pluripotent character trait, at which cells can only distinguish through each embryonic germ stack. After a few divisions, the pluripotency character trait starts to fade and the distinguishing ability has become more lineage constrained, where its cells are becoming multipotent, indicating they could only transform into the cells connected to a cell or tissue of origin.10 Many researchers believe that adult stem cells should be used in stem cell therapies.6,17

The stem cells can be transformed into a wide range of specialized functional cell types.3,18 In response to injury or maturation, those same stem cells can propagate in massive quantities.19 Adult, embryonic, and induced pluripotent stem cells are examples of stem cell-based therapies.14,15,1921 The stem cells, due to their capability to distinguish the specific cell types requisite for a diseased tissue regeneration, can provide an effective solution, while tissue and organ transplantation are considered necessary.10 The sophistication of stem cell-based treatment interventions, on the other hand, probably leads researchers to seek stable, credible, and readily available stem cell sources capable of converting into numerous lineages. As an outcome, it is critical to exercise caution when selecting the type of stem cells to be used in therapeutic trials.12,14,22

Only with the explosive growth of basic stem cell research in recent years, the comparatively recent study sector of Translational Research had also grown exponentially, starting to build on major research knowledge and insight to advance new therapies. Once the necessary regulatory clearances have been obtained, the clinical translation process can start. Translational research is important because it acts as a filtration system, ensuring that only safe and effective therapeutic approaches start making it to the clinic.23 Recent research illustrating, the successful application of stem cell transplantation to patient populations suggests that, such restorative approaches have been used to address a wide variety of complicated ailments of future concerns.19,24

Currently, clinical trials are available for a variety of stem cell-based treatments based on adult stem cells. To date, the WHO International Clinical Experiments Registration process has recorded more than 3000 experiments involved based on adult stem cells. Furthermore, preliminary trials involving novel and intriguing pluripotent stem cell therapies have been registered. These studies findings will assist the ability to comprehend and the timeframes required to obtain effective treatments and it will contribute to a better knowledge of the different disorders or abnormalities.10

The role of stem cells in modern medicine is vital, both for their widespread application in basic research and for the opportunities they provide for developing new therapeutic strategies in clinical practice.6,16 In recent times, the number of studies involving stem cells has expanded tremendously. Globally, thousands of studies claiming to use stem cells in experimental therapies have now been in the investigation field. This may give the impression that such treatments have already been shown to be extremely effective in the context of healthcare. Despite some promising results, the vast majority of stem cell-based therapeutic applications are still in the experimental stage itself.6,25

The stem cells are a valuable resource for understanding organogenesis as well as the bodys continual regenerative capacity. These cells have brought up enormous anticipations among doctors, investigators, patients, and the public at large because of their ability to distinguish into a variety of cell types.25 These cells are necessary for living beings for a variety of reasons and can play a distinguishable role. Several stem cells can play all cell types roles, and when stimulated effectively, they can also repair damaged tissue. This capability has the potential to save lives as well as treat human injuries and tissue destruction. Moreover, different kinds of stem cells could be used for several purposes, including tissue formation, cell deficiency therapeutic interventions, and stem cell donation or retrieval.3,6,26

New research demonstrating that the successful application of stem cell treatments to patients has expressed hope that such regenerative strategies might very well one day is being used to address a wide variety of problematic ailments. Furthermore, clinical trials incorporating stem cell-based therapeutics have advanced at an alarming rate in recent years. Some of these studies had a significant impact on a wide range of medical conditions.10 As a regenerative medicine strategy, cell-based treatment is widely regarded as the most fascinating field of study in advanced science and medicine. Such technological innovation paves the way for an infinite number of transformational and potentially curable solutions to some of humanitys most pressing survival issues. Moreover, it is gradually becoming the next major concern in medical services.11

Modern data, which shows that the successful stem cell transplantation in beneficiaries has raised hopes on the certain rejuvenating approaches, will one day be used to treat many different types of challenging chronic conditions.24 Preliminary data from highly innovative investigations have documented that the prospective advancement of stem cells provides a wide range of life-threatening ailments that have so far eluded current medical therapy.2,10,11 Furthermore, clinical trials involving stem cell-based therapies have advanced at an unprecedented rate. Many of these studies had a significant impact on various disorders.19 Despite the increasing significance of articles concerning viable stem cell-based treatments, the vast majority of clinical experiments have still yet to receive full authorization for stem cell treatments confirmation.11,12,27

Even though the first case of AIDS were noted nearly 27 years ago, and the etiologic agent was noticed 25 years ago, still for the effective control of the AIDS pandemic continues to remain elusive.28 The HIV epidemic started in 1981 when a new virus syndrome defined by a weakened immune system was revealed in human populations across the globe. AIDS showed up to have a substantial reduction in CD4+ cell counts and also elevated B-cell multiplication.15,2831

The agent that causes AIDS, later named HIV, is a retroviral disease with a genomic structural system made up of 2 identical single-stranded RNA particles.3234 According to the Centres for Disease Control and Prevention, with over 1.1 million Americans are presently infected with the virus.31 Compromised immune processes in HIV and AIDS, as well as partial immune restoration, barriers are confirmed for HIV disease eradication. Innovative developmental strategies are essential to maximizing virus protection and enabling the host immune response to eliminate the virus.35

The progression of HIV infection in humans is divided into the following stages of acute infection, chronic infection, and AIDS.15,36 During the acute infection phase, the circulation has a high viral replication, is extremely infectious, that may or may not demonstrate flu-like clinical signs. In the chronic stage, the viral load is lesser than in the acute stage, and individuals are still infectious but may be symptomless. The patient has come to the end stage of AIDS whenever the CD4+ cell count begins to fall below 200 cells/mm or even when opportunistic infections are advanced.15,36

There are currently two types of HIV isolated HIV-1 and HIV-2.15,37,38 However, HIV-1 is the most common cause of AIDS throughout the world, while HIV-2 is only found in a few areas of an African country. Although both virions can cause AIDS, HIV-2 infection is much more likely to occur in central nervous system disorder.15 Besides this, HIV-2 seems to be less infectious than HIV-1, and HIV-2 infection induces AIDS to develop more slowly. Even though both HIV-1 and HIV-2 have a comparable genetic structure comprised of group-specific antigen, polymerase, and envelope genes, their genome organizational structures are differed.15,3739

HIV infiltrates immune cell types, CD4+ T cell types, and monocytes, resulting in a drop in T-cell counts below a critical level and the failure of cell-mediated immune function.15,40 The glycoprotein (gp120) observed in the virion envelope comes into contact with the CD4 particle with high affinity, allowing HIV to infect T cells. By interacting with their co-receptors, CXCR4 and CCR5, the virus infiltrates T cells and monocytes. The retrovirus uses reverse transcriptase to convert its RNA into DNA after attaching it to and entering the host cell. These newly replicated DNA copies then exit the host cell and infect other cells.15,40,41

HIV-1 is a retrovirus and belongs to a subset of retroviruses known as lentiviruses.38,42 Infection is the most common global health concern around the world.15 It has destroyed the millions of peoples health and continues to wreak havoc on the individual health of millions more. The pandemic of HIV-1 is the most devastating plague in the history of humans, as well as a significant challenge in the areas of medicine, public health, and biological science of research activities.34,43 Antiretroviral therapy is the only treatment that is commonly used. This is not a curative treatment; it must be used for the rest of ones life.15 Although antiretroviral therapy has reduced significantly HIV intensity and transmission, the virus has not been eradicated, and its continued presence can lead to additional health issues.44

Infection with the human immunodeficiency virus necessitates entry into target cells, such as through adhesion of the viral envelope to CD4 receptor sites.43 Cellular antiviral responses fail to eliminate the virus, resulting in a gradual depletion of CD4+ T cells and, finally, a severely compromised immune functioning system. Unfortunately, there is no cure for the virus that destroys immunity.4447 In advanced HIV infection, memory T-cell depletion primarily affects cellular and adaptive immune responses, with a minor impact on innate immune responses.48 Globally, 37.7 million people were living with HIV in 2020, and with 1.5 million individuals are infected with the virus.49 The advancement of stem cell therapy and the conduct of implemented clinical trials have revealed that stem cell treatment has high hopes for a range of medical conditions and implementations.15

Stem cell treatment has shown impressive outcomes in HIV management and has the potential to have significant implications for HIV treatment and prevention in the future. In HIV patients, stem cell therapy helps to suppress the viral load even while enabling antiretroviral regimens to be tapered. Interestingly, this practice led to a significant improvement in procedure outcomes soon after starting antiretroviral treatment.15 Stem cell transplantation can alleviate a wide variety of diseases that are currently incurable. They could also be used to create a novel anti-infection therapy strategic plan and to enhance the treatment of immunologic conditions such as HIV infection. HIV wreaks havoc on immune system cells.30,50

The virus infects and replicates within T-helper cells (T-cells), which are white immune system cells. T-cells are also referred to as CD4 cells. HIV weakens a persons immune system over time by pulverizing more CD4 cells and multiplying itself. More pertinently, if the individual has been unable to obtain anti-retroviral medicine, he will progressively fail to control the infectious disease and illnesses.3,15,42

Despite 36 years of scientific research, investigators are still trying to cure human HIV and its potential problem, AIDS.3,5153 HIV continues to face unconquerable dangers to human survival. This virus has developed the potential to avoid anti-retroviral therapy and tends to result in victim death.52 Investigators are still looking for effective and all-encompassing treatment for HIV and its complexity, AIDS.54 This massive amount of data revealed potential AIDS treatment targets.55 Thousands of research projects have yielded a great deal of information on the elusive AIDS life cycle to date.5456 These massive amounts of data supplied possible targets for AIDS treatment.33,55,56 In HIV-infected patients, using stem cell therapy can augment the process of keeping the viral load stagnant by permitting antiretroviral regimens to be tapered.15

Overall, stem cell-based strategies for HIV and AIDS treatment have recently emerged and have become a key area of research. Ideally, effective stem cell-based therapeutic approaches might have several benefits.30 Clinical studies encompassing stem cell therapy have shown substantial therapeutic effects in the treatment of various autoimmune, degenerative, and genetic problems.15,25 Substantial progress has been developed in the treatment of HIV infection using stem cell-based techniques.30

Successfully treated, clinical studies have shown that total tissue recovery is feasible.15,57 In the early 1980s, the first stem cell transplants were accomplished on HIV-positive patients who were unsure of their viral disease. Following the above preliminary aspects, many HIV-positive patients with concurrent malignant tumours or other hematologic disorders underwent allogeneic stem cell transplantation around the world.42 After ART became a common treatment option for patients,58,59 the procedures prognosis improved dramatically. In addition, a retrospective study of 111 HIV+ transplant patients demonstrated a mildly lower overall survivorship performance in comparison to an HIV-uninfected comparison group.60

Earlier, the primary problem for people living with HIV and AIDS was immunodeficiency caused by a loss of productive T-cells. Some clinicians intended to replenish lost lymphocytes through adoptive cell transplants in the initial days before efficacious antiretroviral therapy options were available. Immunologically, it is relatively simple in an isogeneic condition, as illustrated on HIV-positive individuals with just a correlating identical twin who received T-lymphocytes and stem cell transfusions to rebuild the weak immune status of the patient.60 Cell therapy transfusion may be used to remove resting virion genomes from CD4+ immune cells and macrophages mostly through genome-editing or cytotoxic anti-viral cells.15,60 Cell technology and stem cell biological reprogramming developments have made a significant contribution to novel strategies that may give confidence to HIV healing process.3 However, human embryonic stem cells can be distinguished into significant HIV target cells, according to several research findings.30,61,62

Initially, stem cell transplantation was believed to influence the clinical significance of HIV infection, but viral regulation was not accomplished in the discipline. Moreover, improvements in stem cell transplants utilizing synthetic or natural resistant cell resources, in combination with novel genetic manipulative tactics or the advancement of cytotoxic anti-HIV effector cells, have significantly accelerated this sector of HIV cell management.60 Multiple techniques are being introduced to overcome HIV, either through protecting cells from infectious disease or by continuing to increase immune responses to the viral infection.30 The various methods are as follows: Bone marrow stem cells Therapies, Autologous stem cell transplantations, Hematopoietic stem cell transplantation, Genetical modifications of Hematopoietic stem cells (HSCT), HSCT and HAART therapeutic approach, Human umbilical cord mesenchymal stem cell transplantation, Mesenchymal stem/stromal cells (MSCs) applications, CCR5 Delta32/Delta32 Stem-Cell Transplantation, CRISPR and stem cell applications, Induced Pluripotent Stem Cells applications.

According to the findings, circulating replicative HIV remains the most significant threat to effective AIDS therapy. As a result, a method for conferring resistance to circulating HIV particles is required. The effective viral burden in the human body would be significantly reduced if it were possible to defeat reproducing HIV particles.43,44 For the treatment of AIDS, a restorative approach that relies on bone marrow stem cells has been suggested.52 The proposed treatment method captures and eventually destroys circulating HIVs using receptor-integrated red blood cells. Red blood cell membranes can be equipped with the CD4 receptor and the C-C chemokine receptor type 5 and C-X-C chemokine receptor type 4 co-receptors, which will selectively bind circulating HIV particles.15,30,32,33,43,44,46,6365

The term autologous pertains to blood-forming stem cells obtained from the patient for use as a source of fresh blood cells followed by high-dose chemotherapeutic agents.66 Lymphoma is still the biggest cause of mortality in HIV patients. Autologous stem cell recovery or transplantation with high-dose treatments has long been supported as a treatment for certain types of cancer in HIV-negative patients, including leukaemia and lymphoma. Individuals over the age of 65, as well as those with health problems such as HIV, were excluded from initial transfusion experiments. Moreover, the treatment regimen mortality of transplantation has also been reduced significantly due to its use of peripheral blood stem cells rather than bone marrow and the use of newer marginal conditioning therapeutic strategies. HIV-infected clients may be able to utilize enough stem cells for an autologous transplant advancement in HIV management. High-dose Autologous stem cell transplant (ASCT) treatments are better than conventional treatment in people with relapsed non-Hodgkin lymphoma, according to randomized trial evidence. Similarly, studies on HIV-negative people with Hodgkin Lymphoma have shown that ASCT would provide patients with repetitive illness with long-term progression-free survival.66,67 Even so, the clinical trial on Allogeneic Hematopoietic Cell Transplant for HIV Patients with Hematologic Malignancies report was explained as, the cell-associated HIV DNA and inducible infectious virus were not detectable in the blood of patients who attained complete chimerism.68

The study on long-term multilineage engraftment of autologous genome-edited hematopoietic stem cells in nonhuman primates report findings was Genome editing in hematopoietic stem and progenitor cells (HSPCs) is a potential innovative approach for the treatment of numerous human disorders. This report shows that genome-edited HSPCs engraft and contribute to multilineage repopulation following autologous transplantation in a clinically relevant large animal model, which is an important step toward developing stem cell-based genome-editing therapeutics for HIV and possibly other illnesses.69

Research on comprehensive virologic and immune interpretation in an HIV-infected participant again just after allogeneic transfusion and analytical interruption of antiretroviral treatment findings are the instance of HIV-1 cure having followed allogeneic stem cell transplantation (allo-SCT), resulting allo-SCTs in HIV-1 positive participants have failed to cure the disease. It describes adjustments in the HIV reservoir in a single chronically HIV-infected client who had undergone allo-SCT for acute lymphoblastic leukaemia treatment and was obtaining suppressive antiretroviral treatment.

To estimate the size of the HIV-1 reservoir and describe viral phylogenetic and phenotypic modifications in immune cells, the investigators just used leukapheresis to obtain peripheral blood mononuclear cells (PBMCs) from a 55-year-old man with chronic HIV infection prior and after allo-SCT. Once HIV-1 was found to be unrecognizable by numerous tests, including the PCR measurement techniques both of overall and fully integrated HIV-1 DNA, recompilation virus precise measurement by significant cell input quantifiable viral outgrowth assay, and in situ hybridization of intestine tissue, the client accepted to an analytic treatment interruption (ATI) with recurrent clinical observing on day 784 post-transplantation. He continued to remain aviremic off ART until ATI day 288, once a reduced virus rebound of 60 HIV-1 copies/mL resulted, which expanded to 1640 HIV-1 copies/mL five days later, urging ART reinitiation. Rebounding serum HIV-1 action sequences were phylogenetically distinguishable from pro-viral HIV-1 DNA discovered in circulating PBMCs before transplantation. It was indicated that allo-SCT tends to result in significant reductions in the magnitude of the HIV-1 reservoir and a >9-month ART-free cessation from HIV-1 multiplication.34

The Impact of HIV Infection on Transplant Outcomes after Autologous Peripheral Blood Stem Cell Transplantation: A Retrospective Study of Japanese Registry Data reported as ASCT is a successful treatment option for HIV-positive patients with non-Hodgkin lymphoma and multiple myeloma (MM). HIV infection was associated with an increased risk of overall mortality and relapse after ASCT for NHL in a study population.70

The procedure of delivering hematopoietic stem cells mostly through intravenous infusion to restore normal haematopoiesis or treat cancer is known as hematopoietic stem cell transplantation.71 There has recently been a rise in the desire to develop strategies for treating HIV/AIDS diseases employing human hematopoietic stem cells,30 along with this Hutter and Zaia were evaluated the background of Haematopoietic stem cell transplantation (HSCT) in HIV-infected individuals.42

Attempts to use HSCT as a technique for immunologic restoration in AIDS patients or as a therapeutic intervention for malignant tumours were initially insufficient. Regretfully, in the absence of sufficient ART, HSCT seemed to have no impact on the evolution of HIV infection, and the majority of the patients ended up dead of rapidly deteriorating immunosuppression or reoccurring lymphoma or leukaemia. A specific instance report described how an un-associated, matched donor supplied allogeneic HSCT to a patient with refractory lymphoma. The virus was unrecognizable by isolating or PCR of peripheral blood mononuclear cells commencing on day 32 after transplantation. Although HIV-1 was unrecognizable by cultural environment or PCR of several tissues examined at mortem, the patient died of recurring lymphoma on day 47. Another client who obtained both allogeneic HSCT and zidovudine had similar results, with HIV-1 becoming unnoticeable in the blood by PCR analysis. In some other particular instances, a 25-year-old woman with AIDS who obtained an allogeneic HSCT from a corresponding, unfamiliar donor after controlling with busulfan and cyclophosphamide and ART with zidovudine and IFN-2 regimen continued to live for 10 months before falling victim to adult respiratory distress. However, PCR testing of autopsy tissues revealed that they were HIV-1 negative.72

Recent research discovered significant progress towards the clinical application of stem cell-based HIV therapeutic interventions, principally illustrating the opportunity to effectively undertake a large-scale phase two HSC-based gene therapy experiment. In this investigation, the research team used autologous adult HSCs that had been transduced to a retroviral vector that usually contains a tat-vpr-specific anti-HIV ribozyme to develop cells that were less vulnerable to productive infection,73 whereas vector-containing cells have been discovered for extended periods (more than 100 weeks in most people) and CD4+ T cell gets counted were significantly high within anti-HIV ribozyme treating people group compared with the placebo group, the impacts on viral loads were minimal. The studys success, even so, is based on the realization that a stem cell-based strategy like this is being used as a more conventional and efficacious therapeutic approach.30 Some other latest clinical studies used a multi-pronged RNA-based strategic plan which included a CCR5-targeted ribozyme, an shRNA targeting tat/rev transcripts, and a TAR segment decoy.74

These crucial research findings are explained on lentiviral-based gene therapy vectors that can genetically manipulate both dividing and non-dividing HSCs and are less likely to cause cellular changes than murine retro-viral-based vectors. Long-term engraftment and multipotential haematopoiesis have been demonstrated in vector-containing and expressing cells, according to the researchers. Whereas the antiviral effectiveness was not reviewed, the results demonstrate the strategys protection, which helps to expand well for the possibility of a lentiviral-based approach in the upcoming years.30

A further approach, with a different emphasis, has been started up in the hopes of trying to direct immune function to target specific HIV to overcome barriers to attempting to clear the virus from the patient's body. These strategies use gene treatment innovations on peripheral blood cells to biologically modify cells so that they assert a receptor or chimeric particle that enables them to especially target a specific viral antigen,75 deception of HIV-infected peoples peripheral blood T cells raises issues to be addressed, such as the effects of ongoing HIV infection and ex vivo modification on the capabilities and lifetime of peripheral blood cells. Further to that, the above genetically manipulated cells would demonstrate their endogenous T cell receptors, and the representation of the newly introduced receptor could outcome in cross-receptor pairing, resulting in self-reactive T cells. Most of these deficiencies could be countered by enabling specific developmental strategies to take place that can start generating huge numbers of HIV-specific cells in a renewable, consistent way that can restore defective natural immune activity against HIV.30

One strategy being recognized is the application of B cells obtained from HSCs to demonstrate anti-HIV neutralizing specific antibodies. While animal studies have shown that neutralizing antibodies could protect against infection, and extensively neutralizing antibodies have been noticed in some HIV-infected persons, safety from a single engineered antibody might be exceptional.76,77 Realizing antibody binding and virus neutralization may assist in the development of chimeric receptors or single-chain therapeutic antibodies with recognition domains for other techniques that identify cellular immunity against HIV-infected cells.78,79 Thereby, genetically modifying HSCs to generate B cells that produce neutralizing anti-HIV specific antibodies, or engineering HSCs to enable multipotential haematopoiesis of cells that express a chimeric cellular receptor usually contains an antibody recognition domain, indicate one arm of an HSC-based engineered immunity process.30

A further technique of using HSCs that were genetically altered with molecularly cloned T-cell receptors or chimeric molecules particular to HIV to yield antigen-specific T cells. The basic difference in this strategy is that the cells produced from HSCs after standard advancement in the bone marrow and thymus are made subject to normal central tolerance modalities and are antigen-specific naive cells, and therefore do not have the ex-vivo manipulation and impaired functioning or exhaustion problems that other external cell modification methods would have. In this context, the latest actual evidence research using a molecularly cloned T cell receptor particular to an HIV-1 Gag epitope in the aspect of HLA-A*0201 revealed that HSC altered in this ability can progress into fully functioning, mature HIV specialized CD8+ T cells in human thymic tissue that conveys the acceptable constrained HLA-A*0201 particles.80 This explores the possibility of genetically engineering HSCs with a molecularly cloned receptor and signifies a step toward a better understanding and application of initiated T cell responses, which would probably result in the eradication of HIV infection from the body, similar to the natural immune function of other virus infections and pathogenic organisms.30

In an allogeneic transplantation, donor stem cells replace the patients cells.66 Allogeneic hematopoietic stem cell transplantation (HSCT) has appeared as one of the most potent treatment possibilities for many people who suffer from hemopoietic system carcinomas and non-malignant ailments.81 Both HIV-cured people have received HSCT utilizing CCR5 132 donor cells.82,83 This implies that HIV eradication necessitates a decrease in the viral reservoir through the myeloablative procedures,8486 Having followed that, immune rebuilding with HIV-resistant cells was carried out to prevent re-infection.45 The possibility of adoptive transfer of ex vivo-grown, virus-specific T-cells to prevent and control infectious diseases (eg, Cytomegalovirus and EBV) in immunocompromised patients helps to make adoptive T-cell treatment a feasible strategy to inhibit HIV rebound having followed HSCT.81,87,88

The Engineered Zinc Finger Protein Targeting 2LTR Inhibits HIV Integration in Hematopoietic Stem and Progenitor Cell-Derived Macrophages: In Vitro Study, the researchers investigated the efficacy and safety of 2LTRZFP in human CD34+ HSPCs. Researchers used a lentiviral vector to transduce 2LTRZFP with the mCherry tag (2LTRZFPmCherry) into human CD34+ HSPCs. The study findings suggest that the anti-HIV-1 integrase scaffold is an enticing antiviral molecule that could be utilised in human CD34+ HSPC-based gene therapy for AIDS patients.89

The fundamental element of HIV management is stem cell genetic modification, which involves genetically enhanced patient-derived stem cells to overcome HIV infection. In this sector, numerous experimental studies, in vitro as well as in vivo examinations, and positive outcomes for AIDS patients have been conducted.65,74 Genetic engineering for HIV-infected individuals can provide a once-only intervention that minimizes viral load, restores the immune system, and minimizes the accumulated toxicities concerned with highly active antiretroviral therapy (HAART).73 HSCs can be genetically altered, permitting for the addition of exogenous components to the progeny that protects them from direct infectious disease and/or enables them to target a specific antigen. Besides that, HSC-based strategies can enhance multilineage hemopoietic advancement by re-establishing several arms of the immune function. Eventually, as HSCs can be produced autologously, immunologic tolerance is typically high, enabling effective engraftment and subsequent distinction into the fully functioning mature hematopoietic cells.30

The utilization of human HSCs to rebuild the immune function in HIV disease is one application that tries to preserve newly formed cells from HIV infection, while another attempts to develop immune cells that attack HIV infected cells. While each initiative has many different aspects at the moment, they represent huge attention to HIV/AIDS therapies that, most likely when integrated with the other therapeutic approaches, would result in the body trying to overcome the obstacles needed for the virus to be effectively cleaned up.30

While HSC transplantation technique and processes are not accurately novel, as they are commonly and effectively used to address a wide variety of haematological diseases and malignant neoplasms,90 trying to combine them with a gene therapeutic strategy represents a unique and possibly potent therapeutic approach for HIV and AIDS-related ailments. As the results of HIV-infected patients who obtained autologous HSCT continued to improve, there was growing interest in genetically altered stem cells that were tolerant to HIV disease. Multiple logistical challenges have impeded the advancement of genetically modified hematopoietic stem cells as a conceivable therapeutic option for HIV/AIDS.72,73

UCLAs Eli and Edythe Broad Center for Restorative Medicine and Stem Cell Studies is one bit closer to constructing an instrument to arm the bodys immune system to attack and defeat HIV. Dr. Kitchen et al are the first ones to disclose the use of a chimeric antigen receptor (CAR), a genetically manipulated molecule, in blood-forming stem cells. In the experiment, the research team introduced a CAR gene into blood-forming stem cells, which were then moved into HIV-infected mice that had been genetically programmed. The scientists found that CAR-carrying blood stem cells efficiently transformed into fully functioning T cells that have the ability to kill HIV-infected cells in mice. The outcome was an 80-to-95 percentage reduction in HIV levels, suggesting that stem-cell-based genetic engineering with a CAR might be a viable and effective approach for treating HIV infection among humans. The CAR initiative, according to Dr. Kitchen, is much more able to adapt and ultimately more efficient, which can conceivably be used by others. If any further experiment showcases keep promising, the scientists expect that a practice based on their strategy will be accessible for clinical development within the next 510 years.91

HSCT and HAART therapeutic approaches in treating HIV/AIDS as the emergence of highly active antiretroviral therapy (HAART) in the 1990s improved survival rates of HIV infection, leading to a major dramatic drop in the occurrence of AIDS and AIDS-related mortalities. As an outcome, there is much less involvement with using HSCT as a therapy for HIV infection.28,33,43,67,86

A randomized clinical trial of human umbilical cord mesenchymal stem cell transplant among HIV/AIDS immunological non responders investigation, the researchers examined the clinical efficacy of transfusion of human umbilical cord mesenchymal stem cells (hUC-MSC) for immunological non-responder clients with long-term HIV disease who have an unmet medical need in the aspect of effective antiretroviral therapy. From May 2013 to March 2016, 72 HIV-infected participants were admitted in this stage of the randomized, double-blind, multi-center, placebo-controlled dose-determination investigation. They were either given a high dose of hUC-MSC of 1.5106/kg body weight as well as small doses of hUC-MSC of 0.5106/kg body weight, or a placebo application. During the 96-week follow-up experiment, interventional and immunological character traits were analysed. They found that hUC-MSC therapy was both safe and efficacious among humans. There was a significant rise in CD4+ T counts after 48 weeks of treatment in both the high-dose (P 0.001) and low-dose (P 0.001) groups, but no changes in the comparison group.92

One interesting invention made by a team of UC Davis investigators is the recognition of a particular form of stem cell that can minimize the quantity of the virus that tends to cause AIDS, thus dramatically increasing the bodys antiviral immune activity. Mesenchymal stem/stromal cells (MSCs) furnish an incredible opportunity for a creative and innovative, multi-pronged HIV cure strategic plan by augmenting prevailing HIV potential treatments. Even while no antivirals have been used, MSCs have been able to increase the hosts antiviral responses. MSC therapeutic approaches require specialized delivery systems and good cell quality regulation. The studys findings lay the proper scientific foundation for future research into MSC in the ongoing treatment of HIV and other contagious diseases in the clinical organization.35

Infection with HIV-1 necessitates the existence of both specific receptors and a chemokine receptor, particularly chemokine receptor 5 (CCR5).46 Resistance to HIV-1 infection is attained by homozygozygozity for a 32-bp removal in the CCR5 allele.93 In this investigation, stem cells were transplanted in a patient with severe myeloid leukaemia and HIV-1 infection from a donor who was homozygous to Chemokine receptor 5 delta 32. The client seemed to have no viral relapses after 20 months of transplantation and attempting to stop antiretroviral medicine. This finding highlights the essential role that CCR5 tries to play in HIV-1 infection maintenance.86

In comparison, additional HIV-1-infected people who have received allogeneic stem cell transplants with cells from CCR5 truly wild donors did not have long-term relapses from HIV-1 rebound, with 2 of these patients trying to report viral reoccurrence 12 as well as 32 weeks after analytic treatment interruption, respectively. Among these 2 patients, allogeneic stem cell transplantation probably reduced but did not eliminate latently HIV-infected cells, enabling persistent viral reservoirs to activate viral rebound. This viewpoint may not rule out the potential that allogeneic hematopoietic stem cell transplantation might result in a much more comprehensive or near-complete elimination of viral reservoirs, enabling long-term drug-free relapse of HIV-1 infection in some contexts.84 As just one report demonstrated a decade earlier, a curative treatment for HIV-1 remained elusive. The Berlin Patient has undergone 2 allogeneic hematopoietic stem cell transplantations to cure his acute myeloid leukaemia utilizing a potential donor with a homozygous genetic mutation in HIV coreceptor CCR5 (CCR532/32).15,34,46,64,65,72,82,84,86,9496 Other similar studies with CCR5 receptor targets are as follows: Automated production of CCR5-negative CD4+-T cells in a GMP compatible, clinical scale for treatment of HIV-positive patients,97 Mechanistic Models Predict Efficacy of CCR5-Deficient Stem Cell Transplants in HIV Patient Populations,98 Conditional suicidal gene with CCR5 knockout.99

Clustered regularly interspaced short palindromic repeats CRISPR/Cas9 is a promising gene editing approach that can edit genes for gain-of-function or loss-of-function mutations in order to address genetic abnormalities. Despite the fact that other gene editing techniques exist, CRISPR/Cas9 is the most reliable and efficient proven method for gene rectification.100103

Genome engineering employing CRISPR/Cas has proven to be a strong method for quickly and accurately changing specific genomic sequences. The rise of innovative haematopoiesis research tools to examine the complexity of hematopoietic stem cell (HSC) biology has been fuelled by considerable advancements in CRISPR technology over the last five years. High-throughput CRISPR screenings using many new flavours of Cas and sequential and/or functional outcomes, in specific, have become more effective and practical.104,105

The power of the CRISPR/Cas system is that it can specifically and efficiently target sequences in the genome with just a single synthetic guide RNA (sgRNA) and a single protein. Cas9 is directed to the specific DNA sequence by the sgRNA, which causes double stranded breaks and activates the cells DNA repair processes. Non-homologous end joining can cause insertiondeletion (indel) substitutions at the target location, whereas homology-directed repair can use a template DNA to insert new genetic material.104,106

The possibility for CRISPR/Cas9 to be used in the hematopoietic system was emphasised as pretty shortly after it was initiated as a new genome editing method.106,107 The efficiency with which CRISPR-mediated alteration can be used to evaluate hematopoietic stem/progenitor and mature cell function via transplantation. As a result, hematopoietic research has significantly advanced with the implementation of these technologies. Whilst single-gene CRISPR/Cas9 programming is a significant tool for testing gene function in primary hematopoietic cells, high-throughput screenings potentially offer CRISPR/Cas9 an even greater advantage in hematopoietic research.104

While understanding human haematological disorders requires the ability to mimic diseases, the ultimate goal is to transfer this innovation into therapies. Despite significant advancements in CRISPR technology, there are still barriers to overcome before CRISPR/Cas9 can be used effectively and safely in humans. CRISPR has also been used to target CCR5 in CD34+ HSPCs in an effort to make immune cells resistant to HIV infection, as CCR5 is an important coreceptor for HIV infection.104

CRISPR is a modern genome editing technique that could be used to treat immunological illnesses including HIV. The utilization of CRISPR in stem cells for HIV-related investigation, on the other end, was ineffective, and much of the experiment was done in vivo. The new research idea is about increasing CRISPR-editing efficiencies in stem cell transplantation for HIV treatment, as well as its future perspective. The possible genes that enhance HIV resistance and stem cell engraftment should be explored more in the future studies. To strengthen HIV therapy or resistance, double knockout and knock-in approaches must be used to build a positive engraftment. In the future, CRISPR/SaCas9 and Ribonucleoprotein (RNP) administration should be explored in the further investigations.108 As well as some different title studies were explained the effectiveness of the CRISPR gene editing technology on the management of HIV/AIDS including: CRISPR view of hematopoietic stem cells: Moving innovative bioengineering into the clinic,104 CRISPR-Edited Stem Cells in a Patient with HIV and Acute Lymphocytic Leukaemia,109 Sequential LASER ART and CRISPR Treatments Eliminate HIV-1 in a Subset of Infected Humanized Mice,110 Extinction of all infectious HIV in cell culture by the CRISPR-Cas12a system with only a single crRNA,111 HIV-specific humoral immune responses by CRISPR/Cas9-edited B cells,112 CRISPR-Cas9 Mediated Exonic Disruption for HIV-1 Elimination,113 RNA-directed gene editing specifically eradicates latent and prevents new HIV-1 infection,114 CRISPR/Cas9 Ablation of Integrated HIV-1 Accumulates Pro viral DNA Circles with Reformed Long Terminal Repeats,115 CRISPR-Cas9-mediated gene disruption of HIV-1 co-receptors confers broad resistance to infection in human T cells and humanized mice,116 Inhibition of HIV-1 infection of primary CD4+ T-cells by gene editing of CCR5 using adenovirus-delivered CRISPR/Cas9,117 Transient CRISPR-Cas Treatment Can Prevent Reactivation of HIV-1 Replication in a Latently Infected T-Cell Line,118 CCR5 Gene Disruption via Lentiviral Vectors Expressing Cas9 and Single Guided RNA Renders Cells Resistant to HIV-1 Infection,119 CRISPR/Cas9-Mediated CCR5 Ablation in Human Hematopoietic Stem/Progenitor Cells Confers HIV-1 Resistance In Vivo.109

Induced pluripotent stem cells (iPSCs) have significantly advanced the field of regenerative medicine by allowing the generation of patient-specific pluripotent stem cells from adult individuals. The progress of iPSCs for HIV treatment has the potential to generate a continuous supply of therapeutic cells for transplantation into HIV-infected patients. The title of the study is reported on Generation of HIV-1 Resistant and Functional Macrophages from Hematopoietic Stem Cellderived Induced Pluripotent Stem Cells. In this investigation, researchers used human hematopoietic stem cells (HSCs) to produce anti-HIV gene expressing iPSCs for HIV gene therapy. HSCs were dedifferentiated into constantly growing iPSC lines using 4 reprogramming factors and a combination anti-HIV lentiviral vector comprising a CCR5 shRNA and a human/rhesus chimeric TRIM5 gene. After directing the anti-HIV iPSCs toward the hematopoietic lineage, a large number of colony-forming CD133+ HSCs were acquired. These cells were distinguished further into functional end-stage macrophages with a normal phenotypic profile. Upon viral challenge, the anti-HIV iPSC-derived macrophages displayed good protection against HIV-1 infection. Researchers have clearly shown how iPSCs can establish into HIV-1 resistant immune cells and explain their prospective use in HIV gene and cellular therapies.120

Some other similar titles of the studies reported on the effectiveness of IPSCs on HIV/AIDS managements are as follows: Generation of HIV-Resistant Macrophages from IPSCs by Using Transcriptional Gene Silencing and Promoter-Targeted RNA,121 Generation of HIV-1-infected patients gene-edited induced pluripotent stem cells using feeder-free culture conditions,122 A High-Throughput Method as a Diagnostic Tool for HIV Detection in Patient-Specific Induced Pluripotent Stem Cells Generated by Different Reprogramming Methods,123 Genetically edited CD34+ cells derived from human iPS cells in vivo but not in vitro engraft and differentiate into HIV-resistant cells,124 Engineered induced-pluripotent stem cell-derived monocyte extracellular vesicles alter inflammation in HIV humanized mice,125 Sustainable Antiviral Efficacy of Rejuvenated HIV-Specific Cytotoxic T Lymphocytes Generated from Induced Pluripotent Stem Cells.126

Recently, one HIV patient appeared to be virus-free after having undergone a stem-cell transfusion in which their WBCs were changed with HIV-resistant variations.84 Timothy Ray Brown also noted as the Berlin patient, who is still virus-free, was the first individual to undertake stem-cell transplantation a decade earlier. The most recent patient, like Brown, had a type of leukaemia that was vulnerable to chemo treatments. They required a bone marrow transplantation, which involved removing their blood cells and replacing them with stem cells from a donor cell.5,31,34,41,127130 Rather than simply choosing a suitable donor, Ravindra Gupta et al chose one who already had 2 copies of a mutant within the CCR5 gene,128,131 which provides resistance to HIV infection.3

Additionally, this gene encodes for a specific receptor of white blood cells that are assisted in the bodys immunological responses. The transplant, according to Guptas team, completely replaced the clients White cells with HIV-resistant forms.41,83 Cells in the patients blood disrupted expressing the CCR5 receptor, making it unfeasible for the clients form of HIV to infect the above cells again. The scientists determined that the virus had been cleared from the patients blood after the transplantation. Besides that, after 16 months, the client has withdrawn antiretroviral treatment. The infection was not detected in the most recent follow-up, which occurred 18 months after the treatment was discontinued. Adam, also known as the London patient, was the second person to be cured of HIV as a result of a stem cell transfusion. This discovery is an important step forward in HIV research because it may aid in the detection of potential future therapeutic interventions. It must be noted, but even so, that this is not an extensively used HIV treatment. For HIV-infected patients, antiretroviral drugs have been the foremost therapeutic option.3,31,41,94,129,130 It also encourages many investigators and clinicians to look at the use of stem cells in the treatment of a wide range of serious medical conditions. The reprogramming abilities of stem cells, as well as their accessibility, have created a window of opportunity in medical research. The clinical utility of stem cells is forecast to expand rapidly in the coming years.

On Feb 15, 2022, scientific researchers confirmed that a woman had become the 3rd person in history to be successfully treated for HIV, the virus that causes AIDS, after just receiving a stem-cell transfusion that has used cells from cord blood. Within those transplant recipients, adult hematopoietic stem cells have been used; these are stem cells that eventually develop into all blood cell types, which include white blood cells, these are a vital component of the immune framework. Even so, the woman who had fairly recently been completely cured of HIV infection had a more unique experience than that of the 2 men who were actually cured before her.132

The clients physician, Dr. JingMei Hsu of Weill Cornell Medicine in New York, informed them that, she had been discharged from the hospital just 17 days after her procedure was performed, even with no indications of graft vs host ailment. The woman was HIV-positive but also had acute myeloid leukaemia, a blood cancer of the bone marrow that affects blood-forming cells. She had likely received cord blood as a successful treatment for both her cancer and HIV once her doctors decided on a potential donor well with HIV-blocking gene mutation. Cord blood comprises a high accumulation of hematopoietic stem cells; the blood is obtained during a childs birth and donated by the parents.132

The patients donor was partly nearly matched, and she received stem cells from a close family member to enhance her immune function after the transfusion. The procedure was performed on the woman in August of 2017. She chose to discontinue taking antiretroviral drugs, the standardized HIV intervention, 37 months upon her transfusion. After more than 14 months, there is no evidence of the viral infection or antibodies against it in her blood. Umbilical cord blood, in reality, is much more commonly accessible and simpler to try to match to beneficiaries than bone marrow. Perhaps, some research suggests that the method could be more available to HIV patients than bone marrow transplantation. Nearly 38 million people worldwide are infected with HIV. The potential for using partly matched umbilical cord blood transplantation increases the chances of choosing appropriate suitable donors for these clients considerably.132

It is really exciting to see the earlier terminally ill diseases of being effectively treated. In recent times, there has been a surge of focus on stem cell research.3 Stem cell therapy advancements in inpatient care are receiving a growing amount of attention.20 HIV/AIDS has been and remains a significant health concern around the world. Effective control of the HIV pandemic will necessitate a thorough understanding of the viruss transmission.32

Despite concerns about full compliance and adverse reactions, HAART has demonstrated to be able to succeed and is a sign specifically targeted form of treatment against HIV advancement. As illustrated by the first case of HIV infection relapse attained by bone marrow transplant, anti-HIV HPSC-based stem cell treatment and genotype technology have established a possible future upcoming technique to try to combat HIV/AIDS.

Investigators have conducted experiments with engineering distinct anti-HIV genetic traits trying to target different phases of HIV infection utilizing advanced scientific modalities. In numerous in vivo and in vitro animal studies, HSPCs and successive mature cells were secured from HIV infection by trying to target genetic factors in the infection. Anti-HIV gene engineering of HSPCs is safe and efficacious.15

The number of stem-cell-based research trials has risen in recent years. Thousands of studies claiming to use stem cells in experimental therapies have been registered worldwide. Despite some promising results, the majority of clinical stem cell technologies are still in their early life. These achievements have drawn attention to the possibility of the potential and advancement of various promising stem cell treatments currently in development.11

HIV remains a major danger to humanity. This virus has developed the ability to evade antiretroviral medication, resulting in the death of individuals. Scientists are constantly looking for a treatment for HIV/AIDS that is both effective and efficient.52 The 1st treatments in HIV+ clients were conducted in the early 1980s, even though they were cognizant of their viral disease. Following these early cases, allogeneic SCT was used to treat HIV+ patients with associated cancer or other haematological disorders all over the world. Stem cell transplantation developments have also stimulated the improvement of innovative HIV therapeutic approaches, especially for large goals like eradication and relapse.60

Numerous stem cell therapy progressions have been recognized with autologous and allogeneic hematopoietic stem cell transplantation, as well as umbilical cord blood mesenchymal stem cell transplant in AIDS immunologic non-responders. Whereas this sector continues to advance and distinguishing directives for these cells become much more effective, totipotent stem cells such as hESC and the recently reported induced pluripotent stem cells (iPSC) could be very useful for genetic engineering methods to counter hematopoietic abnormalities such as HIV disease.133135

Immunocompromised people are at a higher risk of catching life-threatening diseases. The perseverance of latently infected cells, which is formed by viral genome inclusion into host cell chromosomes, is a significant challenge in HIV-1 elimination. Stem cell therapy is producing impressive patient outcomes, illustrating not only the broad relevance of these strategies but also the huge potential of cell and gene treatment using adult stem cells and somatic derivative products of pluripotent stem cells (PSCs).

Stem cells have enormous regeneration capacity, and a plethora of interesting therapeutic uses are on the frontier. This is a highly interdisciplinary scientific field. Evolutionary biologists, biological technicians, mechanical engineers, and others that have evolved novel concepts and decided to bring them to medical applications are required to make important contributions. Further to that, recent advancements in several different research areas may contribute to stem cell application forms that are novel. Several hurdles must be conquered, however, in the advancement of stem cells. On the other hand, this discipline appears to be a promising and rapidly expanding research area.

Stem cell-based approaches to HIV treatment resemble an innovative approach to trying to rebuild the ravaged bodys immune system with the utmost goal of eliminating the virus from the body. We will probably see effective experiments from the next new generation of stem cell-based strategies shortly, which will start serving as a base for the further development and use of these techniques in a range of treatment application areas for other chronic diseases.

Animals

All animal experiments were performed in accordance with the institutional guidelines of the Institute of Laboratory Animals, Graduate School of Medicine, Kyoto University (Kyoto, Japan), and all experimental protocols were approved by the same institute. The reporting in this manuscript followed the recommendations in the ARRIVE guidelines. For euthanasia, mice were intraperitoneally administrated with a mixture of Medetomidine (0.3mg/kg body weight), Midazolam (4mg/kg body weight), and Butorphanol (5mg/kg body weight). SM22-Cre mice(Tg (Tagln-cre)1Her/J, Stock# 004746) and dual fluorescent membrane-localized tdTomato/eGFP (mT/mG) mice (B6.129(Cg)-Gt(ROSA)26Sortm4(ACTB-tdTomato, -EGFP)Luo/J, Stock# 007676) were purchased from the Jackson Laboratory. SM22 -Cre mice were bred with flox mT/mG mice to produce mT/mGflox/wt: SM22-Cre+(SM22mT/mG) mice. For embryos, SM22 -Cre mice were paired overnight with flox mT/mG mice. The morning after mating was considered 0.5days post-coitus (dpc).

Male and female SM22mT/mG mice, 610weeks of age, were used as the cell source. CFs were isolated as described previously26. Media and buffers were prepared according to a previous paper26. The descending aortas and inferior venae cavae were cut. The hearts were perfused with EDTA buffer from the right ventricle. The ascending aortas were clamped. The clamped hearts were removed, transferred to a dish containing EDTA buffer, and perfused with EDTA buffer from the left ventricle (LV). The hearts were transferred to a dish of perfusion buffer, and perfused with perfusion buffer from the LV. The hearts were transferred to a dish of collagenase buffer and perfused with collagenase buffer from the LV. The ventricles were transferred to the other dish of collagenase buffer, gently teased apart into pieces, and triturated. Stop solution was added to the cell-tissue cell suspension. The supernatants obtained via gravity settling three times for 10min in perfusion buffer were collected as nonCMs. The nonCMs were centrifuged at 300g for 5min, resuspended in DMEM containing 10% fetal bovine serum (FBS) and penicillinstreptomycin (Wako, #168-23191), plated on cell culture dishes and cultured for 67days. Almost all cells were fibroblasts after the culture.

Bone marrow was extracted from the femurs and tibias of euthanized mice and differentiated in bone marrow macrophage differentiation media (RPMI 1640 containing 10% fetal bovine serum (FBS), penicillinstreptomycin, 20g/mL recombinant mouse M-CSF (Biolegend, #576404), and 0.1mM/L 2-mercaptoethanol (Wako, #133-14571)). Seven days after being harvested, BMDMs were stimulated with recombinant mouse TGF-1 (Biolegend, # 763102) for 1 or 7days, for RNA or for Flow cytometric analysis, respectively. To investigate whether Cre-recombination occurs during the differentiation process from HSCs to BMDMs, bone marrow cells were harvested and cultured in bone marrow macrophage differentiation media containing with TGF-.

Hearts in 6-week-old mice were perfused with cold phosphate-buffered saline (PBS) and 4% paraformaldehyde, removed, and fixed with 4% paraformaldehyde (PFA) for 3h. The hearts of Embryos at 17.5 dpc were removed, washed with cold PBS and fixed with 4% PFA for 3h. The hearts were incubated in 10%, 20% and 30% sucrose diluted in PBS. The samples were then embedded in OCT compound (Sakura Finetek Japan), frozen and stored at 80. Cryosections (8m thick) were obtained using a Leica cryostat.

For immunofluorescence analysis, sections were first washed with PBS, permeabilized with PBS containing 0.1% Triton-X, and washed with PBS containing 0.1% Tween 20. The sections were then incubated in blocking buffer (PBS containing, 0.1% Tween 20, 1% BSA, and 10% normal donkey serum (Jackson ImmunoResearch, #017-000-121)) for 1h at room temperature. Primary antibodies diluted in blocking buffer were added and incubated overnight at 4. The following primary antibodies were used: anti-SMA (1:100) (Goat, Novus Biologicals, #NB300-978), anti-Vimentin (1:100) (rabbit, Cell Signaling Technology, #5741S), anti-CD68 (1:200) (rat, Bio Rad, #MCA1957GA), and anti-CD31 (1:100) (rabbit, Novus Biologicals, # NB100-2284). Then, the slides were washed three times in PBS containing 0.1% Tween 20 for 5min each, and incubated with Alexa Fluor 647 (ThermoFisher, #A-31573 or Abcam, #ab150155) or Alexa Fluor Plus 680 (ThermoFisher, #A32860) against the appropriate species (diluted at 1:500) for 1h at room temperature. The slides were washed three times in cold PBS for 5min each. Finally, the slides were mounted with VECTASHIELD Antifade Mounting Medium with DAPI (Vector Laboratories, #H-1200-10).

Immunofluorescence images were acquired on an Axio Observer (Carl Zeiss) (5objective) or SP8 Falcon (Leica) (63objective) and analyzed with Zen software (Carl Zeiss) or LAS X (Leica), respectively.

Single cardiac cell suspensions were generated as described previously27. Hearts were perfused with cold PBS and finely minced and digested in Hanks Balanced Salt Solution (HBSS) with Collagenase 2 (500 U/ml) (Worthington Biochemical, #LS004176) for 30min at 37C. Next, the hearts were digested in HBSS with Collagenase/Dispase (1mg/mL) (Merck, #11097113001) for 20min at 37C. To deactivate the enzymes, the samples were washed with cold HBSS. The solutions were passed through a 40m cell strainer (Corning, #352340). Red blood cell lysis was performed with ACK lysis buffer (0.16M ammonium chloride, 10mM Potassium bicarbonate and 0.1mM EDTA). The samples were washed with FACS buffer (HBSS with 25mM 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), 2% FBS and 2mM ethylenediaminetetraacetic acid (EDTA)) and resuspended in 300 L of FACS buffer. Heart samples were blocked with TruStain FcX Plus (0.5 L/100 L) (Biolegend, #156604) for 5min at 4.

Peripheral blood samples were collected from the inferior vena cava of anesthetized mice using a heparin-contained syringe. Red blood cell lysis was performed with ACK lysis buffer. The samples were washed with FACS buffer and resuspended. Peripheral blood samples were blocked with TruStain FcX Plus for 5min at 4.

Bone marrow cells were obtained by flushing femurs and tibias with RPMI supplemented with 25mM HEPES and 10% FBS. The suspensions were passed through a 40m cell strainer. After the red blood cells were lysed, the samples were washed with FACS buffer and resuspended.

BMDMs were collected after harvesting as described before and were blocked with TruStain FcX Plus for 5min at 4.

Cells were stained with monoclonal antibodies at 4C for 20min in the dark. The samples were washed twice, and the final resuspension was made in 500 L of FACS buffer. 7-AAD was used to exclude dead cells. Flow cytometric analysis was performed on BD FACS ARIAII platforms. Complete lists of antibodies and flow cytometry gating strategies are provided in Supplementary Tables 1 and 2, respectively.

Cell lines, such as Induced Pluripotent Stem Cells (iPSC) and human Embryonic Stem Cells (hESC) are recognized as having high growth potential; as a result, many research entities and companies are making significant investments in R&D pertaining to iPSC- and hESC-derived products.

Pricing of stem cell transplantation varies from region to region. For instance, the cost of transplantation in the U.S. is higher than that in Germany or China. In March 2018, Alofisel by TiGenix received approval for marketing in Europe. This was the first allogeneic stem cell therapy to be approved in Europe. Furthermore, revenue for certain products varies for the country; for instance, products like INVOSSA received approval for marketing in Korea but have yet to receive marketing authorization in the U.S. Growth is also influenced by the commercialization of unauthorized stem cell treatments revenue generation.

Global Cell Therapy Market Definition

Therapy in which viable cells are injected, grafted, or implanted into a patient to effectuate a medicinal effect is known ascell therapy; for instance, In immunotherapy, T-cells capable of fighting cancer cells via cell-mediated immunity are transplanted, and stem cells are grafted to regenerate diseased tissues.

Cellular therapies hold a great therapeutic promise across various clinical applications. This has resulted in substantial global investments in research and their clinical translation. Rapid advances in stem cell research have the potential to fulfill the unmet demand of pharmaceutical entities, biotech entities, and doctors in disease management. Several unknown therapies are in clinical development.

Furthermore, government and private funding agencies are constantly offering grants to support projects at various stages of clinical trials, increasing the number of ongoing clinical trials.

Research on human embryonic stem cells is ethically controversial. Harvesting embryonic stem cells involves the destruction of human embryos, raising a moral concern. In addition, stringent regulations for obtaining Intellectual Property Rights (IPR) for products or materials used in research are major restraints for commercializing these services. Ethical approval should be obtained to store cell lines and tissues in biorepositories to avoid the usage of tissue for illegal purposes or to identify proxy diseases to claim insurance. Moreover, controversies surrounding the use of embryonic stem cells for research impede the market growth in several regions

The study categorizes the cell therapy market based on use type and therapy type at the regional and global levels.

The analysis of the cell therapy market is based on the use of stem cells for clinical and research purposes. The research-use segment dominated the market for the global cell therapy market and accounted for the largest revenue share of 58.3% in 2021. Currently, cell therapies (stem & non-stem cells) are majorly being used for research projects, which in turn, has led to a large revenue share of this segment in 2021. Cell-based therapies are all possibilities for the replacement, repair, restoration, and regeneration of damaged tissues, cells, and organs. As an alternative to traditional treatment strategies, researchers are investing heavily in developing effective and safe cell-based treatments.

‘World’s Greatest Tuba-Playing Car Salesman’ Bounces Back after Leukemia, Thanks to Wilmot Team – URMC

Returning home after a Fathers Day trip to New York City with his daughter in 2016, Scott Kesel thought he had come down with the flu. Bloodwork showed his blood platelets were lower than normal. He followed up with his regular physician and was given the news: he had chronic myelomonocytic leukemia (CMML).

CMML is a rare type of blood cancer that starts in the bone marrow, where blood cells are made. It can involve other areas of the body. There are only about 1,100 cases in the U.S. each year and its more common in people over age 60.

As a Canandaigua resident, Scott started his cancer journey at Wilmot Cancer Institutes Sands Cancer Center at F.F. Thompson. His oncologist laid out all the options: chemo and a stem cell transplant.

Knowing he would need a transplant, his team at Sands had him transfer to Wilmots Hematology team, where he began seeing Jason Mendler, M.D., and his transplant doctor, Omar Aljitawi, M.B.B.S.

He had chemotherapy at Wilmot, where he got to know the infusion nursing staff.

They have put a mindset in place thats so beneficial to the patient, he says.

For a stem cell transplant, his brother was the closest match they could find, although he was only a half-match. That left the option for a haplo-identical transplant available. Historically, it was required to have a closer match in order to do a transplant. With a haploidentical transplant, the donor is only half-matched. Its a newer procedure that is not available at all transplant centers, but the doctors at Wilmot have been performing the surgery since 2015.

He underwent the transplant but, unfortunately, in Scotts case, it didnt work.

For a short period, Scott went to another institution for a clinical trial. Unfortunately, that didnt work either. He developed pancreatitis and had to drop out of the trial. He also experienced cold agglutinin disease, which caused his immune system to attack his red blood cells. Cold temperatures can trigger it and he had to stay at Wilmot for about a month in a temperature-controlled room, set at 80 degrees at all times, to overcome it.

Once that resolved, the team at Wilmot suggested another treatment option to try on Scotts leukemia: a transplant with stem cells from an umbilical cord donation. Umbilical cord blood stem cells came from Australia and Spain to try to save Scotts life. He had only two cord blood units available and he needed both to have a successful transplant, which was his only viable chance to potentially cure his leukemia. Along with the cord blood, he also had radiation therapy with Louis Constine, M.D.

He had nothing but good things to say about the team that took care of him while he was hospitalized on Wilmot Cancer Centers sixth floor, the Blood and Marrow Transplant Unit.

It was exceptional. They were so friendly and accommodating right from the very beginning, he says. It wasnt limited to nurses. Theres medical technicians on the floor that were so friendly and became very good friends.

Scott Kesel (right) with Jason Mendler, M.D., at the 2019 Wilmot Warrior Walk

Thankfully, this time the transplant took. As of June 2022, Scott has been in remission for three-and-a-half years. He credits his team for getting him there.

Its an incredible group of people, he says.

But its not just his team hes grateful for. He appreciates that his life has returned basically back to normal, despite the tumultuous COVID pandemic that happened shortly after his transplant.

Hes gotten back to work and to hobbies he enjoys outside work.

I happen to be the worlds greatest tuba playing car salesman, he jokes.

This summer and fall, he has 28 gigs lined up, with different music groups around the region to keep him busy, and he looks forward to hunting and fishing during his free time.

For it all, he feels fortunate.

You have to be grateful for the outcome, he says. I got a lot of support remotely from people in my community who used the opportunity to promote bone marrow registration and blood drives, which was awful nice.

He adds, Im grateful that I ended up at Wilmot. I really couldnt have been in a better place.

Next-day manufacture of a novel anti-CD19 CAR-T therapy for B-cell acute lymphoblastic leukemia: first-in-human clinical study | Blood Cancer Journal…

Preclinical evaluation of FasT CAR-T cellsFasT CAR-T (F-CAR-T) proliferation in vitro

To characterize the in vitro proliferative capacity of F-CAR-T cells, F-CAR-T and C-CAR-T cells were manufactured in parallel (Supplementary Methods, and Fig. S1) using T-cells from 6 B-ALL patients. To investigate the ex vivo proliferation of F-CAR-T, frozen CD19 F-CAR-T and C-CAR-T cells from each patient were thawed and stimulated with irradiated CD19-expressing K562 cells. The number of CD19-targeting CAR-T cells was then determined during the course of cell expansion in vitro. As shown in Fig. 1A, upon CD19 antigen stimulation, F-CAR-T proliferation was much more robust compared to C-CAR-T proliferation. On day 17 post co-culture, F-CAR-T expanded 1205.61226.3 fold (MeanSD), while C-CAR-T expanded only 116.437.2 fold (MeanSD), (p=0.001). To characterize the mechanism underlying the superior proliferative ability of F-CAR-T, we purified CD19+ CAR-T cells from both F-CAR-T and C-CAR-T. The expression of genes involved in cell proliferation, cell cycle, and apoptosis was analyzed using Nanostring (detailed gene sets are in Table S2). Gene expression profiles showed higher F-CAR-T expression scores for genes associated with cell cycle regulation (F-CAR-T vs. C-CAR-T, p<0.01) and lower expression scores for apoptosis-related genes (F-CAR-T vs. C-CAR-T, p<0.05) in F-CAR-T cells (Fig. S2A).

A Ex vivo cell proliferation of F-CAR-T and C-CAR-T derived from B-ALL patients (n=6) (***P=0.001, F-CAR-T vs. C-CAR-T, d17, unpaired student two-tailed t-test). B Tscm, Tcm, and Tem were characterized by surface staining of CD45RO and CD62L and analyzed with flow cytometry (***P<0.001 comparing F-CAR-T and C-CAR-T). C T-cell exhaustion was characterized by PD-1, LAG3, and TIM-3 staining; Statistical analyses of the percentage of PD1+ LAG3+ Tim3+ (***P<0.001, comparing F-CAR-T and C-CAR-T), unpaired student two-tailed t-test). D RTCA assay was used to examine the specific killing of HeLa-CD19 cells. Growth of target HeLa-CD19 or HeLa cells were monitored dynamically. E CD19+ target Nalm6-Luc cells or F Raji-Luc cells were co-cultured with either F-CAR-T or C-CAR-T for 6h. Target cell killing efficacy was calculated by luciferase activity. NS, P>0.05 F-CAR-T vs. C-CAR-T (unpaired student t-test, two-tailed). F-CAR-T FasT CAR-T, C-CAR-T conventional CAR-T, Tcm (CD45RO+CD62L+) T central memory cells, Tem (CD45RO+CD62L) T effector memory cells, Tscm (CD45ROCD62L+) T stem cell memory, PD1 programmed cell death protein 1, TIM-3 T cell immunoglobulin and mucin domain containing-3, LAG3 lymphocyte-activation gene 3, RTCA real-time cell analyzer, E:T effector cells: target cells, NT normal T-cell.

Phenotypes of unstimulated F-CAR-T from three healthy donors were analyzed by flow cytometry. The CD45ROCD62L+ population was 45.7%2.2% which was comparable to the un-transduced T-cells (data not shown). Upon stimulation with CD19+ tumor cells for 9 days, C-CAR-T central memory cells (Tcm, CD45RO+CD62L+ and effector memory cells (Tem, CD45RO+CD62L) were 56.62%11.97% and 40.48%9.70%, respectively, among the C-CAR-T cells (Fig. 1B and Figs. S2B and S2). In contrast, Tcm cells (87.92%4.36%) was predominant in F-CAR-T, with only a small fraction of Tem (7.84%3.79%). In addition, F-CAR-T cells demonstrated more abundant T stem cell memory (Tscm) (3.841.22% vs 2.342.48%, p<0.05) than C-CAR-T cells. We also examined the exhaustion status of the stimulated CAR-T cells. A higher percentage of PD-1+LAG3+Tim3+T-cells were detected in the C-CAR-T (11.19%2.54%) compared to F-CAR-T (3.59%2.51%, p<0.001) (Fig. 1C). Together these data indicated that the F-CAR-T exhibited a younger phenotype and was less exhausted compared to C-CAR-T.

We used a real-time cell analyzer (RTCA) assay to measure the cytotoxicity of F-CAR-T and C-CAR-T against CD19+ cells in vitro. F-CAR-T and C-CAR-T killing of Hela-CD19 target cells were comparable using this assay (Fig. 1D). Similar levels of IFN- and IL-2 production were also observed (Fig. S2D). In a luciferase-based cytotoxicity assay, CD19+ B leukemia cell lines, Raji and Nalm6, were both effectively killed to similar or better levels at different E:T ratios (Fig. 1E, F).

To compare the in vivo cytotoxicity of F-CAR-T and C-CAR-T, severe immunodeficient NOG mice were engrafted with Raji-luciferase cells. One week after the tumor grafts were established, F-CAR-T and C-CAR-T were intravenously injected at various doses. The engrafted tumors progressed aggressively in control groups with either vehicle alone or control T-cells (Fig. 2A). In contrast, F-CAR-T or C-CAR-T treatment greatly suppressed tumor growth in a dose-dependent manner (Fig. 2A). In the high dose group (2106/mice), both F-CAR-T and C-CAR-T eliminated the tumor rapidly. However, in the low dose group (5105/mice), F-CAR-T showed more effective tumor-killing compared to C-CAR-T. On day 20, mice in the low dose F-CAR-T group became tumor-free, while C-CAR-T treated mice exhibited tumor relapse (Fig. 2A). We examined the CAR-T cell expansion in vivo after infusion. As shown in Fig. 2B, both F-CAR-T and C-CAR-T began to expand in the peripheral blood 7 days after infusion. C-CAR-T cell numbers reached their peak on day 14 and receded on day 21. In contrast, the F-CAR-T cell number peaked on day 21 and declined to a baseline level on day 28. F-CAR-T not only persisted longer but also underwent 26 folds greater expansion than C-CAR-T (Fig. 2B).

A Raji-Luc cell engraftment NOG mice were given high dose (2106/mice, n=3) and low dose (5105/mice, n=3) F-CAR-T/C-CAR-T along with control groups. Tumor growth was monitored with IVIS scan once every 3 days; B CAR-T expansion in peripheral blood of mice was analyzed by flow cytometry (n=6). ***P<0.001 for F-CAR-T HD vs. C-CAR-T HD; F-CAR-T LD vs. C-CAR-T LD; F-CAR-T HD vs. F-CAR-T LD; C-CAR-T HD vs. C-CAR-T LD (two-way ANOVA statistical analysis); C Schematic of the Nalm6 (1106) xenograft model, CAR-T (2106) infused 1 day after cyclophosphamide (20mg/kg) treatment. Bone marrow infiltration of F-CAR-T was analyzed 10 days after CAR-T infusion (n=3); D CD45+CD2 F-CAR-T vs. C-CAR-T in peripheral blood of mice were analyzed by flow cytometry; *P<0.05 (unpaired student two-tailed t-test). IVIS in vivo imaging system, PB peripheral blood, i.v. intravenous, HD high dose, LD low dose, Cy cyclophosphamide; *p<0.05; #: number.

We examined the BM infiltration of F-CAR-T cells after infusion into Nalm6-bearing mice (Fig. 2C). A larger population of CAR-T cells was observed 10 days after infusion in BM in F-CAR-T infused group than that in the C-CAR-T group (p<0.05) (Fig. 2D), suggesting F-CAR-T cells possessed a better BM homing capability than C-CAR-T.

The chemokine receptor CXCR4 is known to be critical for BM homing of T-cells [25, 26]. Indeed, a higher percentage of CXCR4+ T cells were detected in F-CAR-T than in the C-CAR-T. Interestingly, this phenotype was more pronounced for CD4+ T cells than CD8+ T cells (Fig. S3A). In a two-chamber system, more F-CAR-T cells could be detected in the lower chamber than their C-CAR-T counterparts (Fig. S3B).

Between Jan. 2019 and Oct. 2019, 25 pediatric and adult patients with CD19+R/R B-ALL were enrolled onto our phase 1 trial, including two patients who had relapsed following a prior allo-HSCT. Patient characteristics are detailed in Table 1. The median age of patients was 20 (range: 344) years old. Twenty patients were >14 years old, and five were 14 years old. The median percentage of pre-treatment BM blasts was 9.05% (range: 0.1982.9%). As our pre-clinical studies demonstrated that F-CAR-T cells had a superior expansion capability as compared to C-CAR-T, we infused a relatively low doses of F-CAR-T cells, ranging from 104105 cells/kg: 3.0104 cells/kg (n=2), 6.5 (5.867.43)104 cells/kg (n=9), 1.01 (1.01.16)105 cells/kg (n=12), 1.52(1.471.56)105 cells/kg (n=2), (Fig. S4). The median time from apheresis to the infusion of CD19+F-CAR-T cells was 14 days (range: 1220). Although the manufacturing time of F-CAR-T was next day, the quality control time and detailed final product releases including sterility testing require a minimum of 710 days to complete. In addition, transportation of cell products requires approximately two days. Of the 25 patients who received CD19 F-CAR-T infusion, 22 (88%) received bridging chemotherapy between apheresis and lymphodepleting chemotherapy to control rapid disease progression (Table S3).

F-CAR-T cells were manufactured successfully for all patients. The mean transduction efficiency of F-CAR-T was 35.4% (range: 13.170.3%) (Fig. S5A). Both CD4+/CAR+ (mean, 49.6%; range: 13.673.2%) and CD8+/CAR+ (mean, 41.5%; range: 20.677.7%) subsets were present in the CD3+CAR+ T cell subsets of all products. The mean proportion of Tscm, Tem, and Tcm cells in the CD3+CAR+ T cell subsets of all products was 23.3% (range: 3.5545.3%), 33.2% (range: 17.267.9%), and 36.1% (range: 20.758.1%), respectively (Fig. S5B). F-CAR-T products exerted significant IFN- release and cytotoxic effects against the CD19+ cell line HELA-CD19 (Fig. S5, C, D).

All 25 infused patients experienced adverse events (AEs) of any grade, with 25 (100%) experiencing grade 3 or higher adverse events. No grade 5 events related to F-CAR-T treatment were observed (Table 2).

CRS occurred in 24 (96%) patients with 18 (72%) grade 12 CRS,6 (24%) of grade 3, and no grade 4 or higher CRS (Fig. S6). In the >14 years old group, 16/20 (80%) patients developed mild CRS, and only 2/20 (10%) developed grade 3 CRS. For 14 years old patients, 2/5 (40%) had mild CRS, yet 3/5 (60%) experienced grade 3 CRS (Table S4). ICANS was observed in 7 (28%) patients, with 2 (8%) grade 3 ICANS occurring in patients >14 years old and 5 (20%) grade 4 ICANS all occurring in patients 14 years old. No grade 5 ICANS was developed (Fig. S7 and Table S4). The most frequent presentation of CRS was fever, particularly a high fever of >39C. The first onset of CRS symptoms occurred between day 3 and 8 post-CAR-T infusion with a median onset at day 4 (range: 110 days). The most common symptoms of ICANS were seizure (5/7) and depressed consciousness (5/7). The median time to ICANS onset from CAR-T cell infusion was 7 days (range: 58), and the median time to resolution was 2 days (Fig. S7). All CRS and ICANS events were managed including early intervention when fever of 39C persisted for 24h. Sixteen (64%) patients received tocilizumab with a median total dose of 160mg (range: 160320mg). Twenty-one (84%) patients received corticosteroids including dexamethasone (median total dose, 43mg; range: 4127mg) and or methylprednisolone (median total dose, 190mg; range: 401070mg). The vast majority of these patients discontinued corticosteroids within 2 weeks. The change in IL-6, IFN-, IL-10, and GM-CSF levels after infusion are selectively shown in Fig. S8. The peak levels of these four cytokines were observed between day 710. Among all 21 cytokines examined, only post-infusion IL-6 levels were associated with moderate to severe CRS and/or ICANS (Figs. S9 and S10).

Superior in vivo proliferation and persistence of F-CAR-T compared to C-CAR-T cells were observed regardless of dose levels. The median peak level was reached on day 10 (range: 714 days) with 1.9105 transgene copies/g of genomic DNA (range: 0.225.2105 transgene copies/g of genomic DNA) by qPCR and 83 F-CAR-T cells per l blood (range: 42102 F-CAR-T cells per l blood) by FCM (Fig. 3A, B). No significant differences were observed among the different dose groups in the mean F-CAR-T copies peak (Fig. 3C). Importantly, there was no significant difference in the mean F-CAR-T copies peak between patients who received corticosteroids compared to those who did not (Fig. 3D).

Purple, dose level 1; black, dose level 2; blue, dose level 3; red, dose level 4; C Comparison of the mean peak copy number of F-CAR-T cells in peripheral blood at each dose level. Statistical significance was determined by the MannWhitney test. D Comparison of the mean peak copy number of F-CAR-T cells in peripheral blood with or without steroids. Statistical significance was determined by the MannWhitney test.

Fourteen days after F-CAR-T cell infusion, all patients achieved morphologic CR including 2/25 with CR and 23/25 CR with incomplete hematologic recovery (CRi), which further improved to 11/25 CR and 14/25 CRi 28 days post F-CAR-T (Table 1 and Fig. 4). More importantly, 23/25 (92%) had the minimal residual disease (MRD)-negative remission on day 14 and day 28 after F-CAR-T treatment. Patients achieving remission through CAR-T were given the option to proceed to allo-HSCT. With a median time of 54 days (range: 4581 days) post F-CAR-T infusion, 20 of 23 patients with MRD-negative status decided to pursue consolidative allo-HSCT including one patient who received a 2nd transplant. As of 18 October 2021, with a median follow-up duration of 693 days (range: 84973 days) among the 20 patients who had received allo-HSCT, one patient relapsed on day 172 and died 3 months after relapse, and four patients died from transplant-related mortality (TRM) including infection (n=3) and chronic GVHD (n=1) on day 84, day 215, day 220, and day 312, respectively. The other 15 patients remained in MRD-negative CR with a median remission duration of 734 days (range: 208973) except for one who became MRD-positive on day 294 with CD19+ disease. Among the other three patients (F05, F06, F16), one remained in MRD-negative CR on day 304, one remained in MRD-negative CR until day 303, received allo-HSCT but died from an infection on day 505, and one was lost to follow-up after day 114. Two patients who had MRD-positive CR after infusion withdrew from the study on day 42 and day 44, respectively, to seek other studies.

Clinical outcomes and consolidative allo-HSCT for the 25 patients who were treated with F-CAR-T therapy are shown. On day 28, 23/25 patients achieved MRD-negative CR/CRi. With a median time of 54 days (range: 4581) post F-CAR-T infusion, 20 of 23 patients with MRD-negative status received consolidative allo-HSCT. Among the 20 patients, 1 patient (F23) relapsed on day 172 and died 3 months after relapse. Four patients (F04, F09, F11, F12) died from transplant-related mortality (TRM) including infection (n=3) and chronic GVHD (n=1) on day 84, day 215, day 220, and day 312, respectively. The remaining 15 patients were in MRD-negative CR except for one (F18) who became MRD-positive on day 294. Among the other 3 patients (F05, F06, F16), 1 remained MRD-negative CR on day 304, 1 remained in MRD-negative CR until day 303, received allo-HSCT, and subsequently died from an infection on day 505. One patient was lost to follow-up after day 114. MRD minimal residual disease, CR complete remission, Allo-HSCT allogeneic hematopoietic stem cell transplantation.

F-CAR-T/T ratio in cerebrospinal fluid (CSF) was evaluated by FCM in 13/25 patients with available samples (Table S5). Between days 10 and 32, 9 patients were found to have considerable F-CAR-T penetration in their CSF, ranging from 40.65 to 79.2%, including 4 who developed severe ICANS. Among the other 4 patients, F-CAR-T cell abundance in the CSF ranged from 1.29% to 3.57%, and none experienced severe ICANS. Patients with higher levels of CAR-T in PB on day 10 consistently had higher levels of CAR-T in CSF with the exception of patient F15. Notably, CAR-T cells were still detectable in the CSF on day 101 with a 2.36% CAR-T/T ratio in patient F06, who also had undetectable circulating CAR-T cells at the same time.

In addition, concentrations of seven cytokines (IL-1b, IL-6, IL-10, IFN-, TNF-, MCP-1, and GM-CSF) in CSF samples from the above 10 of 13 patients were measured. Specifically, IL-1b was not detected in any of the 10 patients, and only one patient had detectable GM-CSF. For the other five cytokines, patients with severe ICANS had higher IL-6 levels in contrast to patients without severe ICANS, and the difference between the median level of IL-6 among these two groups of patients was statistically significant (Fig. S11). We did not observe significant differences among the other 4 cytokines between the two groups of patients. No clear relation between the CSF cytokine levels and the F-CAR-T/T % was observed.

Proteases implicated in ulcerative colitis – ASBMB Today

Ulcerative colitis, or UC, is a form of inflammatory bowel disease characterized by chronic and relapsing large intestine inflammation. Genetics account for only a minority of UC cases; hence, to develop treatments, researchers need to understand better the environmental contributions to this condition.

Gut microbes are in perpetual contact with the gastrointestinal tract, so they comprise important but poorly defined environmental variables contributing to UC development. Many studies have reported changes in gut microbiome composition in patients with UC compared to healthy individuals. While that suggests a potential role for gut microbes in UC pathogenesis, researchers have yet to pinpoint the causative microbes and associated bacterial proteins.

Dennis Wolans lab at Scripps Research is interested in identifying small-molecule activators and inhibiting bacterial enzymes involved in proliferation of human disease. Wolan said he was curious about what bacterial enzymes of the microbiome contribute to UC development.

Many publications have focused on the role of the microbiome in both health and disease states, he said. Most of these were focused on the taxonomical and phylogenic differences in the microbiome. But what about the associated bacterial proteins? What proteins are these gut bacteria making in disease conditions, and how are these interacting with the human body?

One protein of interest was serine proteases, a type of proteolytic enzyme that cleaves peptides at the serine amino acid. Researchers long have recognized that they coordinate many physiological processes and play key roles in regulating the inflammatory response. Previous studies have suggested increased proteolytic activity in microbial samples harvested from people with inflammatory disorders such as UC and Crohns disease.

Peter ThuyBuon, a graduate student and later a postdoc in the Wolan lab, led a project to study differential protein expression in healthy and UC fecal samples. He and the team described the project in a recent paper in the journal Molecular & Cellular Proteomics. In addition to standard mass spectrometry, ThuyBuon used a small molecular approach called affinity-based proteomic profiling to target and enrich for different types of proteases in the fecal samples.

We showed that there were 176 discrete host and microbial protein groups differentially enriched between healthy and UC patients, Wolan said. Furthermore, further enrichment of these proteins showed significantly higher levels of serine proteases in UC patients.

This finding has inspired exciting future research questions. For example, are elevated serine proteases the driver of UC or merely the effect of UC disease progression?

There is a lot of exciting work to be done using these findings, Wolan said. Future molecular studies should focus on how serine proteases might be contributing to UC and whether their levels can be manipulated to modify disease progression.

Functional proteomics has shown the potential role of serine proteases in UC. Future steps will include drug discovery and design of small-molecule regulators of bacterial enzymes.

Wolan said, Ultimately, the moderation of microbiome distribution in UC via external small-molecule intervention can serve as a foundation for UC prevention and treatment.

Cutting Edge: Poop therapy can save your gut, and your life – The Indian Express

The very thought of getting someone elses poop transfused in your body may make you cringe but stool transplant has not only helped patients with gastrointestinal tract issues, it has also saved those who have had bone marrow transplants.

At Deenanath Mangeshkar Hospitals Centre of Excellence in Infectious Diseases and Department of Haematology, Pune, seven of the 11 patients of bone marrow transplants developed Clostridium difficile infection. They were treated with faecal microbial transplant (FMT), also referred to as stool transplant, over the past year.

Research worldwide has shown that a faecal transplant can restore healthy bacteria in the lower intestine which can help control Clostridium difficile or C. diff. According to the Johns Hopkins University School of Medicine, FMT can be more effective than antibiotics for keeping C. diff in check in some cases.

Since C. diff infection can recur and cause colitis (inflammation in the colon), FMT restores good and healthy bacteria, said Dr Parikshit Prayag, infectious disease consultant and in-charge of the Centre of Excellence in Infectious Diseases at Deenanath Mangeshkar hospital.

Dr Sameer Melinkeri, head of the department of haemotology at the hospital, said C. diff infection-related diarrhoea can occur in a normal setting in which antibiotics can be used for treatment. However, antibiotic treatment for recurrent infections can involve one or more courses of medication and their effectiveness comes down with each subsequent bout. FMT can arrest such infections post bone marrow transplant as it can be life-threatening, he added.

FMT is also done for certain disease conditions like Graft vs host disease (GvHD). Most people who undergo a bone marrow transplant suffer from blood cancer. Graft vs host disease can occur at any time after an allogeneic transplant where the donated bone marrow or peripheral stem cells can attack the recipients body. It can develop in the GI tract, skin or liver, Dr Prayag said.

Latest research published in the Journal of International Medical Research and others has shown how FMT is a promising treatment for patients with steroid-resistant GvHD. We have seen clinically relevant results in six of our patients, Dr Prayag said.

So, who can be donors? They are selected based on certain parameters. They should not be immune-compromised or have taken antibiotics over the past six months, says Dr Sampada Patwardhan, head of the department of microbiology at the hospital. Donor screening has to be done carefully. We need to rule out infections, she said.

Procedures on the transplant delivery methods may vary like colonoscopy and use of nasojejunal tube. The recovery may take a week or more and in most cases there are at least two weekly installations of the stool (in liquid form).

Very few centres conduct FMT and among them, the centre at Deenanath Hospital actively treats cases involving bone marrow transplants. At a recent virtual meeting of the International Society of Blood Transfusion, Dr Prayag made a strong case for encouraging stool transplants. The condition of C. diff is also underdiagnosed in the country as there isnt adequate infrastructure to correctly detect the problem, he pointed out.

In fact, FMT is being touted as a treatment option for many gut health issues. In an opinion article published on June 30 in the journal Trends in Molecular Medicine, a team from Harvard Medical School and Brigham and Womens Hospital (BWH) proposes that individuals bank samples of their own gut microbiota when they are young and healthy for potential use later in life in an autologous FMT.

A report in Science Daily quotes corresponding author Yang-Yu Liu, an associate professor of medicine at Harvard and an associate scientist in the Channing Division of Network Medicine at BWH, as saying, The idea of rewilding the human microbiome has taken off in recent years and has been hotly debated from medical, ethical and evolutionary perspectives. It is still unknown if people in industrialized societies can gain some health benefit by restoring their microbiome to an ancestral state. In this paper, we proposed a way to rejuvenate the human gut microbiome.

The report also listed OpenBiome, a non-profit stool bank based in Somerville, Massachusetts, as the first stool bank to offer an option for individuals to bank their own stool for future treatment of C. diff infection. Yang and his colleagues are now looking at if this treatment can be used for other diseases.

Conceptually, the idea of stool banking for autologous FMT is similar to when parents bank their babys cord blood for possible future use. However, there is greater potential for stool banking, and we anticipate that the chance of using stool samples is much higher than for cord blood. But there are many practical issues to implementing this idea, Yang is quoted as saying, hinting at optimal storage and cryopreservation issues.

U.S. Air Force Releases Photos Of Mock B61-12 Nuclear Bomb Test Loaded On B-2A Bomber – The Aviationist

A non-nuclear mock B61-12 Joint Test Assembly (JTA) being prepared for test loading inside the B-2A Spirit stealth bombers bombs bay. (U.S. Air Force photo by Airman 1st Class Devan Halstead)

The U.S. Air Force recently released on the Defense Visual Information Distribution Service (DVIDS) website a series of interesting photos from Whiteman Air Force Base, Missouri. The photos, taken on June 13, 2022, show a high-fidelity, non-nuclear mock B61-12 Joint Test Assembly (JTA) being prepared for test loading inside the B-2A Spirit stealth bombers bombs bay. To our knowledge, these should be the first public photos of the weapon with the Spirit since testing aboard the aircraft has begun few years ago.

The Air Force did not provide many details and did not even mention the name of the bomb, simply stating the 72nd Test and Evaluation Squadron test loads a new nuclear-capable weapons delivery system for the B-2 Spirit bomber. The 72nd TES, a geographically separated unit of Eglin AFBs 53rd Wing based at Whiteman, is in charge of all testing and evaluation of new equipment, software and weapons systems for the B-2 Spirit stealth bomber.

It is not clear what the caption refers to with the term nuclear-capable weapons delivery system. The unofficial Nuclear Matters Handbook of the office of the Deputy Assistant Secretary of Defense for Nuclear Matters, gives us the following definition:

A nuclear weapon delivery system is the military platform and delivery vehicle by which a nuclear weapon is delivered to its intended target in the event of authorized use (by the President of the United States, who retains sole authority to employ nuclear weapons). Most nuclear weapons have been designed for a specific delivery system, making interoperability potentially challenging.

In addition to the mix of silo-based Minuteman III (MMIII) ICBMs, Trident II D5 Life Extension (LE) SLBMs carried on Ohio-class SSBNs, and B-2A and B-52H nuclear-capable heavy bombers, the U.S. nuclear force includes dual-capable aircraft (DCA), that can carry conventional or nuclear weapons.

Judging by this definition, the weapon delivery system in question should be the B-2A bomber, however the fact that the caption mentions the test loading aboard the aircraft might mean that this system is a new weapon rack inside the bombs bay designed to work with the new B61-12. Available public info states that the Spirit was designed to employ a Bomb Rack Assembly (BRA) for conventional munitions and a Rotary Launcher Assembly (RLA) for the delivery of conventional or nuclear weapons.

The BRA was later upgraded between 2003 and 2006 and became a Smart Bomb Rack Assembly capable of carrying as many as 80 independently targeted, JDAM GPS-guided weapons. So, since the new B61-12 in equipped with a guidance kit, it is possible that also the RLA is now being upgraded to use the new bomb. The new bomb variant will replace the B61-7 and B61-11 currently available for the B-2 fleet.

As we already reported, The B61 entered service 50 years ago and has undergone a Life-Extention Program (LEP) to consolidate and replace four legacy bomb variants, the B61 -3, -4, -7, and -11 mods, into the B61-12. The refurbished B61-12 will allow the retirement of the larger B83, becoming the only remaining gravity delivered nuke in the inventory. The bomb will carry a low-yield nuclear warhead with four yield options, reportedly 0.3 kilotons, 1.5 kilotons, 10 kilotons and 50 kilotons, instead of larger warheads like the models it is replacing (which can reach 400 kilotons depending on the variants).

The 12-foot, 825-pound bomb is designed to be delivered from the air in either ballistic or guided-gravity drop modes, thanks to a new Boeing-built tail assembly that includes an Inertial Navigation System (INS) precision-guidance package and two spin rocket motors that improve the bombs stability on its longitudinal axis during the descent. The LEP is said to be increasing the B61s accuracy so much (with a reported 30 m Circular Error Probability instead of the original 100 m) that it will have the same capability against hardened targets as the much more powerful weapons it is replacing.

SOCOM is working on a new and improved Navy SEAL Delivery Vehicle – Business Insider

To remain effective in an era of near-peer warfare and to counter China's growing military, US Special Operations Command and the Navy SEALs are working on two new and improved mini-submarines that are expected to enter service soon.

The two new special-operations mini-subs the Mark 11 Shallow Water Combat Submersible and the Dry Combat Submersible will be the backbone of Naval Special Warfare's submersible fleet for decades to come.

The Mark 11 will replace the Mark 8 Mod 1 mini-sub. The new mini-sub comes with an increased operational range and payload, more advanced sensors, improved navigation systems, and a new command-and-control structure that will allow new technologies to be introduced more efficiently.

At 23 feet long, the Mark 11 will be able to carry six Navy SEALs: two crew and four combat divers. The mini-sub will be to dive to about 165 feet and will be flooded while in use, meaning the SEAL operators will be exposed to the elements and will have to use dry suits and oxygen tanks. (The British Special Boat Service has also ordered the Mark 11.)

SOCOM expects the Mark 11 to hit initial operating capability this summer. Should everything go according to plan, the new SEAL Delivery Vehicle will begin to phase out the Mark 8, which has been in service since the 1980s.

The Dry Combat Submersible is much larger and heavier. The 40-foot mini-submarine will have a vastly longer operational range and greater payload capacity than the Mark 11 and be more comfortable for the 10 commandos two crew and eight combat divers it will be able to carry.

At a recent industry conference, Cmdr. John Conway, SOCOM's program manager for special-operations forces undersea systems, likened the Dry Combat Submersible to "an electric truck" that can do a lot of things at the same time and can be adapted and improved with new sensors and systems in response to future threats and operational environments.

Naval Special Warfare is also looking at "other nontraditional ways to launch" the Mark 11, such as "a containerized solution" off of "some vessel of opportunity or things like that," Navy Cmdr. James Hanlon, SOCOM's program manager for special-operations maritime systems, said at the conference, according to Defense News.

In addition to the new Mark 11 and Dry Combat Submersible, Naval Special Warfare is working on a service-life extension program for the Dry Deck Shelter, which is attached to a submarine's hull and allows SEALs and other combat divers to exit and enter the submarine while underway.

The Navy's six Dry Deck Shelters were built between 1982 and 1991 and were expected to have service lives of 40 years. The planned extension would allow them to operate until the 2050s

The Navy SEAL teams are most well known for their direct-action capabilities. High-profile operations over the last 20 years, including the raid that killed Osama bin Laden, have fostered a belief that all that SEALs do is kick down doors and go after bad guys.

But SEAL teams have other capabilities and are proficient in many skill sets. The SEAL Delivery Vehicles are perhaps one of their most exotic capabilities, and the two SEAL Delivery Vehicle teams specialize in three mission sets: underwater insertion and extraction of special operations troops, underwater special reconnaissance, and underwater special operations.

In addition, SEAL Delivery Vehicle teams can support maritime counterterrorism operations by stealthily moving special operators close to a target that is in or near the water.

Generally, SEAL operators avoid an assignment to a SEAL Delivery Vehicle team because of the extremely difficult mission set. Although all Navy SEALs are combat divers, SEAL Delivery Vehicle team members take combat diving to the next level. Eight- to 10-hour dives are not uncommon.

Naval Special Warfare Command, which oversees the SEALs, has two delivery vehicle teams, which were first stood up in the early 1980s.

SEAL Delivery Vehicle Team One, now based in Hawaii, is dedicated to the West Coast and operations in the Pacific. SEAL Delivery Vehicle Team Two was deactivated in 2008 but reestablished in 2019 amid the shift toward great-power competition. SDVT-2 is based in Little Creek, Virginia, and is the dedicated delivery vehicle unit for the East Coast and operations in Europe.

The delivery vehicle teams are now part of Naval Special Warfare Group 8, which was created in 2020 through the consolidation of two other special warfare groups. The officer who led the group with the delivery vehicle teams was selected to lead Group 8 when it was formed, suggesting SDVs will have an important role going forward.

SEAL Delivery Vehicles are SOCOM's only special-operations submersible capability. In a conflict with China, mini-subs paired with the Navy's attack submarines would be ideal for getting SEALs into tough spots and denied areas, which will be essential for countering China's anti-access/area-denial umbrellaover the Western Pacific.

"Our relationship with our submarine force has never been closer," Rear Adm. Hugh Howard III, commander of Naval Special Warfare Command, told senators in May. "We see the undersea as absolutely critical to deterrence. I think that it is a place that we maintain advantage, and it is a place where we must maintain advantage to critically deter our peer adversaries."
