The HIV drug tenofovir may prevent AIDS transmission when applied rectally as a gel, according to results from a macaque study published in PLoS medicine .

'Use of Larger Versus Smaller Drug-Safety Databases Before Regulatory Approval: The Trade-Offs,' health Affairs: In the Web exclusive, Shelby Reed, an associate professor of medicine at the Duke University Clinical Research Institute, and colleagues evaluate the potential benefits and costs of requiring larger sample sizes in preapproval clinical trials for new prescription drugs.

Unique biochemical crosstalk that enables a fetus to get nutrition and oxygen from its mother's blood just may cause common postpartum blues, researchers say.That crosstalk allows the mother's blood to flow out of the uterine artery and get just a single cell layer away from the fetus' blood, says Dr. Puttur D. Prasad, biochemist in the Medical College of Georgia School of medicine.read more

(Whitehead Institute for Biomedical Research) Short snippets of RNA called microRNAs help to keep embryonic stem cells in their stem cell state. Researchers now have discovered the gene circuitry that controls microRNAs in embryonic stem cells. Mapping the control circuitry of stem cells reveals how they maintain themselves or decide to differentiate, providing key clues for regenerative medicine and reprogramming of adult cells to a stem cell state. These maps also aid our understanding of human development and diseases such as cancer.
