A molecular condom against AIDS
12-11-2006 · EurekAlert!University of Utah scientists designed a "molecular condom" women could use daily to prevent AIDS by vaginally inserting a liquid that would turn into a gel-like coating and then, when exposed to semen, return to liquid form and release an antiviral drug.

- Molecular 'marker' on stem cells aids research, perhaps therapies
12-05-2006 · UT Southwestern Medical Center
A sugar molecule present on embryonic stem cells also has been found on the surface of a type of adult stem cell, a discovery that may help researchers isolate and purify adult stem cells for use in therapies aimed at bone healing, tendon repair and cartilage regeneration, researchers at UT Southwestern Medical Center report.

- AIDS interferes with stem cells in the brain
08-15-2007 · EurekAlert!
Scientists at the Burnham Institute for Medical Research have discovered how HIV/AIDS disrupts the normal replication of stem cells in the adult brain, preventing new nerve cells from forming. Drs. Stuart Lipton, Marcus Kaul, Shu-ichi Okamoto and colleagues uncovered a novel molecular mechanism that inhibits stem cell proliferation and that could possibly be triggered in other neurodegenerative diseases. These findings were published today online by the journal Cell Stem Cell.

- Safety of new microbicide for HIV prevention to be tested in young women in US trial
07-09-2007 · EurekAlert!
In an effort to help stem the tide of the HIV/AIDS epidemic, particularly in women, researchers have launched a clinical safety trial of a topical vaginal microbicide with a unique molecular structure that holds promise for preventing the sexual transmission of HIV. The Microbicide Trials Network is leading the NIH-funded study in which VivaGel is being tested for the first time in sexually active young women to determine its safety, acceptability and ease of use.

- First high-res 3D structures of mammalian HSP90 protein solved
10-12-2007 · EurekAlert!
Dr. Dan Gewirth, Hauptman-Woodward senior research scientist, has just solved the structure of the first mammalian GRP94 protein implicated in immune diseases such as sepsis, AIDS and certain cancers. His work is being published today in a cover article in Molecular Cell. Gewirth's study confirms his hypothesis that this protein -- GRP94 -- is from the same family as the better known HSP90 proteins.

- Food peptides activate bitter taste receptors
01-22-2008 · EurekAlert!
Researchers from the Monell Center and Tokyo University of Agriculture have used a novel molecular method to identify chemical compounds from common foods that activate human bitter taste receptors. The findings may aid development of bitter inhibitors to help make health-promoting bitter foods such as green vegetables more palatable.

- Striking shift seen among newly HIV-infected men regarding partners
12-05-2007 · EurekAlert!
"While the findings showed condom use was up and the number of partners was down, the most startling effect was seen in men choosing to have unprotected intercourse almost exclusively with other HIV-infected individuals. This reflects a systematic shift by men, most of whom are gay, following HIV infection to behaviors that protect their sex partners," said lead author, Wayne Steward, PhD, MPH, assistant professor of medicine at UCSF's Center for AIDS Prevention Studies.

- More aid required for chronic conditions in low income countries
01-17-2007 · EurekAlert!
Chronic conditions such as cardiovascular disease and cancer result in more deaths and account for more years of healthy life lost than most communicable diseases, and yet little international aid is focused on preventing or treating these conditions. Cardiovascular disease causes 30 percent of all deaths globally and 27 percent of deaths in low income countries. By comparison, HIV/AIDS, tuberculosis and malaria, combined, account for 10 percent of all deaths globally and 11 percent of death in developing countries.

- Second pathway behind HIV-associated immune system dysfunction identified
09-30-2007 · EurekAlert!
Researchers at the Partners AIDS Research Center at Massachusetts General Hospital may have discovered a second molecular 'switch' that turns off the immune system's response against HIV. Last year the same team identified a molecule that suppresses the activity of HIV-specific CD8 T cells that should destroy virus-infected cells. Now they describe how a regulatory protein called CTLA-4 inhibits the action of HIV-specific CD4 T cells that control the overall response against the virus.
