Story Summary: Researchers: HIV virus can hide in bone marrowMarch 7, 2010 By RANDOLPH E. SCHMID , AP Science Writer(AP) — The virus that causes AIDS can hide in the bone marrow, avoiding drugs and later awakening to cause illness, according to new research that could point the way toward better treatments for the disease. Finding that hide-out is a first step, but years of research lie ahead. Dr. Kathleen Collins of the University of Michigan and her colleagues report in this weeks edition of the journal Nature Medicine that the HIV virus can infect long-lived bone marrow cellsthat eventually convert into blood cells. Thats an indication that while the drugs battle the active virus, some of the disease remains hidden away to flare up once the therapy is stopped. Thats critical in countries where the treatment is hard to afford and deliver. I dont know how many people realize that although the drugs have reduced mortality we still have a long way to go, Collins said in a telephone interview. That is mainly because we cant stop the drugs, people have to take it for a lifetime.

The U.S. Birth Rate is on the Rise

admin — Thu, 11 Mar 2010 08:09:30 +0000

A record 4.3 million babies were born in the U.S. in 2007, according to a summary of birth statistics published each year in the journal Pediatrics. The birth rate (number of births per 1,000 women) has been climbing for a couple of decades, though it is nowhere near what it was 100 years ago. The record high number of births is due both to a recent trend upward in the birth rate and the larger U.S. population now than 100 years ago.

A noteworthy trend in the data is that women are having their babies later than they did just 15-20 years ago. Birth rates were lower in 2007 than in 1990 for women under 30, but higher in 2007 for women over 30. Also noteworthy is a continued rise in the number of births to unmarried women; it’s now a record 40% of all births.

University of Michigan scientists discover bone marrow can harbor HIV-infected cells

admin — Thu, 11 Mar 2010 05:59:34 +0000

Story Summary: The findings, which appear online March 7 in Nature Medicine, indicate a new target for curing the disease so those infected with the virus may someday no longer rely on AIDS drugs for a lifetime. Antiviral drugs have been effective at keeping the virus at bay. Infected cells are able to live on, undetected by the immune system, and provide the machinery for the virus to reproduce and spread. While further studies are needed to demonstrate that stem cells can harbor the HIV virus, the study results confirm that HIV targets some long-lived progenitor cells, young cells that have not fully developed but mature into cells with special immune functions. When active infection occurs the toxic effects of the virus kill the cell even as the newly made viral particles spread the infection to new target cells. Our finding that HIV infects these cells has clear ramifications for HIV disease because some of these cells may be long-lived and could carry latent HIV for extended periods of time, she says. The new research gives a broader view of how HIV overwhelms the bodys immune system and devastates its ability to regenerate itself. Globally more than 30 million people are infected with HIV, including millions of children….Read the Full Story

Scientists create tiny RNA molecule with big implications for lifes origins

admin — Thu, 11 Mar 2010 03:25:34 +0000

Story Summary: The findings could be a substantial step toward understanding the very origin of Earthly life, the lead researcher contends. The smallest RNA enzyme ever known to perform a cellular chemical reaction is described in a paper published this week in the Proceedings of the National Academy of Sciences. That pioneering work has been carried on further by Yarus, Blumenthal said. If very simple RNA molecules such as the product of the Yarus lab could have accelerated chemical reactions in Earths primordial stew, the chances are much greater that RNA could direct and accelerate biochemical reactions under primitive conditions. Before the advent of RNA, most biologists believe, there was a simpler world of chemical replicators that could only make more of themselves, given the raw materials of the time, Yarus said. If there exists that kind of mini-catalyst, a sister to the one we describe, the world of the replicators would also jump a long step closer and we could really feel we were closing in on the first things on Earth that could undergo Darwinian evolution, Yarus said. Dr Yarus has brought an innovative approach to bear on the key question of how complex processes originated, said Michael Bender, a biologist who oversees protein synthesis grants at the National Institutes of Healths National Institute of General Medical Sciences. — full story– 23 July 2009A small green beetle may have some interesting lessons to teach scientists about optics and liquid crystals – complex mechanisms the insect uses to create a shell so strikingly beautiful. — full story– 9 July 2009Although the fact that we generate new brain cells throughout life is no longer disputed, their purpose has been the topic of much debate. — full story– 9 July 2009Although the fact that we generate new brain cells throughout life is no longer disputed, their purpose has been the topic of much debate.

Lumixyl™ Brightening System

A New Physician-Grade System Designed to Safely Address the Signs of Hyperpigmentation

New York, NY—Envy Medical, Inc., introduces the new Lumixyl™ Brightening System, a revolutionary multi-faceted approach to effectively treat hyperpigmentation without irritation or other side effects associated with prescription Hydroquinone or retinoids. This professional skincare system introduction builds on the success of the Lumixyl Topical Brightening Crème introduced in 2009.

“The Lumixyl Topical Brightening System is an entirely new approach to naturally brighter, more vibrant skin, representing a new physician-grade standard in skincare,” explains Dr. Basil Hantash, MD, PhD, a board certified Stanford-trained dermatologist and vice-chairman of the board at Envy Medical, who also helped develop the Lumixyl peptide technology.

Dr. Hantash

An innovation in skin brightening technology, the four products in the Lumixyl Brightening System work synergistically to target existing hyperpigmentation and to prevent its recurrence. For most patients these formulations can eliminate the need to use hydroquinone or its bi-products, which are controversial due to their potential side effects. Lumixyl products are proven to be powerful but gentle on skin.

“Physicians and the public at large have been calling for a viable alternative to prescription hydroquinone therapies,” commented Envy Medical CEO, Curtis A. Cluff. “We are very pleased to be able to answer that call with a system that provides visible brightening with a safe and non-irritating formula.”

The Lumixyl Topical Brightening System builds on the four products including Active-Prep Cleanser, the Topical Brightening Creme, GlycoPeel 20 Rapid Exfoliating Lotion, and Moisture-Lock Sunscreen SPF 30. The products are ideal for all skin types. Lumixyl Brightening System retails for $270 for four full size products.

Developed by Envy Medical, Inc. and dermatological researchers at Stanford University, Lumixyl products are made exclusively for dermatologists, plastic surgeons and skin oriented aesthetic physicians. The products are manufactured and sold by Envy Medical in the United States and distributed internationally by Toronto Canada-based Basis Medical Technologies.

Virus infections may be contributing factor in onset of gluten intolerance

admin — Wed, 10 Mar 2010 13:09:45 +0000

Story Summary: A research project in the Academy of Finlands Research Program on Nutrition, Food and Health (ELVIRA) has brought new knowledge on the hereditary nature of gluten intolerance and identified genes that carry a higher risk of developing the condition. Research has shown that the genes in question are closely linked with the human immune system and the occurrence of inflammations, rather than being connected with the actual breakdown of gluten in the digestive tract. This is essential, because the condition is often relatively symptom-free, yet it can have serious complications unless treated. The research will be published in a forthcoming issue of Nature Genetics. Gluten intolerance is an autoimmune reaction in the small intestine. The gluten that occurs naturally in grains such as wheat, barley and rye causes damage to the intestinal villi, problems with nutrient absorption and potentially other problems too. Gluten intolerance is an inherited predisposition, and nearly all sufferers carry the genes that play a key part in the onset of the condition. The only known effective treatment is a lifelong gluten-free diet. Journal Reference:Dubois et al. Multiple common variants for celiac disease influencing immune gene expression….Read the Full Story

NIAID media availability: Food allergy-related disorder linked to master allergy gene

admin — Wed, 10 Mar 2010 13:09:43 +0000

Story Summary: People with EoE frequently have difficulty eating or may be allergic to one or more foods. This study further suggests that a suspected so-called master allergy gene may play a role in the development of this rare but debilitating disorder. Little is known about what causes EoE, but the disease runs in families suggesting that specific genes may be involved. This type of study detects markers of genetic variation across the entire human genome and allows researchers to zero in on a region of a chromosome to identify genes that influence health and the development of disease. In this study, the investigators identified changes in genes within a region on chromosome 5 that were highly associated with EoE. One of the genes in this region encodes a protein called thymic stromal lymphopoietin (TSLP). TSLP is made by epithelial cells, which line internal and external surfaces of the body. It has already been described as a master switch that may turn on other allergic diseases, such as asthma and atopic dermatitis (eczema). Future research is needed to determine if these findings might lead to a genetic test for TSLP and whether drugs that block the production or function of TSLP might be useful in treating EoE.

Gene Site Found for a Childrens Food Allergy

admin — Wed, 10 Mar 2010 13:09:42 +0000

Story Summary: Only recently recognized as a distinct condition, EoE, like other allergies, has been increasing over the past 20 years, and its reported incidence of one in 10,000 people may be an underestimate. The hallmark of EoE is swelling and inflammation in the esophagus, accompanied by high levels of immune cells called eosinophils. It can affect people of any age, but is more common among young men who have a history of other allergic diseases such as asthma and eczema. They then replicated the initial findings with additional DNA samples from EoE patients and controls at CHOP. TLSP holds the genetic code to produce a cytokine, a specific signaling protein that regulates inflammatory responses occurring in allergic diseases. Physicians then perform tests to determine which foods a child can or cannot eat. Eosinophilic esophagitis is a highly allergic disease, and one that is rapidly expanding, said allergist Jonathan M. Spergel, M. D. , a co-first author of the study, who sees large numbers of patients with EoE as director of the Center for Pediatric Eosinophilic Disorders at The Childrens Hospital of Philadelphia. Its pediatric research program is among the largest in the country, ranking second in National Institutes of Health funding. In addition, its unique family-centered care and public service programs have brought the 441-bed hospital recognition as a leading advocate for children and adolescents.

Photophobic Chemistry

admin — Wed, 10 Mar 2010 13:09:33 +0000

Ugg… what a pain. The reaction I’m doing today produces a low molecular weight, light-sensitive ?,?-unsaturated ketone as a product. It’s a derivative of methyl vinyl ketone. Not only is it low-boiling, it also polymerizes upon standing in light. Ugg…

Now, I’ve worked with light-sensitive reagents (like the iodomethane and methallyl iodide) before, so I’m comfortable turning off the light and covering the reaction with foil to keep out extraneous photons. That’s not so bad, because when the reaction’s done, you can flip on the light to work up the reaction.

Not so when the product is light sensitive. Gotta keep the light off. Gotta extract in the dark. Gotta dry the organic layer with foil around the flask. Gotta rotovap in the dark with foil around the flask. Worst of all, gotta run a column in the dark. For that, I cut off some of the sides of a cardboard box and used them as a shield to block the light and holed myself up in the dark corner of my hood to run the column. Then gotta rotovap the fractions corresponding to product in the dark in foil. Take the mass in the dark… Ugg. Pain all around. Oh yeah, I forgot I gotta keep the NMR samples in the dark while I acquire the spectra, too.

Plus, gotta keep the product away from light until I set up the next reaction (which is going on right now)… and that’s gotta be in the dark. At least when this reaction’s done, I can turn the lights back on.

Fortunately, the first reaction worked quite well. I ran two multi-gram reactions side by side in the dark and got quantitative yield on both.

So while I run off to find some vitamin D supplements, tell me what the most operationally painful experiment you’ve set up is. I’m sure many of you have stories that make mine seem trivial. What experiment’s the biggest pain to run? I think any reaction involving FOOF (the most awesome, most onomatopoeic molecular formula evah) has to be up there.

Story Summary: The Vilcek Prizes epitomize the mission of the Vilcek Foundation, which was formed by Jan and Marica Vilcek to honor the contributions of foreign-born individuals in the United States. He sees battles raging within a cells nucleus as genes jockey for evolutionary dominance. These clashes can have a long-term impact on organisms, as they sometimes alter the function of essential genes. His lab showed that host proteins can evolve to defeat viral mimicry, providing yet another nuance to a never-ending arms race between hosts and viruses. His lab hypothesized and is testing the model that such a genetic conflict may recurrently drive the onset of reproductive barriers between recently diverged species. He completed his doctoral work in molecular evolutionary biology at the University of Rochester in Rochester, N. Y. , where, under the mentorship of Tom Eickbush, Ph.

Gut Flora Genes Dwarf Human Genome

admin — Wed, 10 Mar 2010 04:34:06 +0000

Story Summary: The challenge is how to do this quickly when you are dealing with millions of genes. The process involves taking lots and lots of short strips of DNA, assembling them into larger sections, and then comparing them to known sequences stored in reference databases and ruling out those known to belong to the human genome. For this study the researchers used fecal samples from 124 Europeans. The study has also revealed a number of clues about how bacteria manage to survive in the rather unhospitable environment of the human gut. The only way to thrive here is to evolve, and this study has unveiled some interesting clues about how they did this. The researchers found that while individual participants of the study had only about 160 of the 1,000 possible species, about 40 per cent of any one one participants gut flora species was also present in around 50 per cent of the other participants.

It was produced by and is freely available thanks to support from Boston Biochem. This special Focuson endocytosis reflects the diversity and complexity of endocytic trafficking processes and their associated machineries. Post-transcriptional control seriesThe regulation of gene expression beyond the level of transcription is much more intricate than previously thought, and involves diverse mechanisms that regulate the processing, stability and localization of RNA species. In this new article series, we assess the basic mechanisms of post-transcriptional control and the interplay between them. This special Focusreflects our current understanding of mechanotransduction — from how cells sense mechanical forces in different tissues to how these mechanical forces are transduced into biochemical signals — in development and disease. Poster on Pluripotent cell isolation for regenerative medicinePluripotent cells offer great promise for regenerative medicine. In this Poster, Christopher Lengner and Rudolf Jaenisch compare and contrast the properties of pluripotent embryonic stem cells with those of laboratory-generated pluripotent cells.

Story Summary: Professor Brown said the next step of the research, which was recently published in Nature Genetics,was to identify more of the genes associated with the disease. He said the work had also led them to identify similarities between the genes that cause AS and those involved in inflammatory bowel diseases and psoriasis. In combination these conditions affect about three percent of Australians.
