An international group of scientists has announced a major expansion of a lingua franca used to describe the activities of genes in living organisms. The expansion provides terms that scientists can use to describe the complex events that occur when a pathogenic or beneficial microbe encounters its host.
Scientists at Forsyth may have moved one step closer to regenerating human spinal cord tissue by artificially inducing a frog tadpole to re-grow its tail at a stage in its development when it is normally impossible.
The U.S. Food and Drug Administration (FDA) has cleared for marketing a modified Colleague Volumetric Infusion Pump which addresses many of the problems that prompted a series of Class I recalls and a product seizure in 2005.
Mayo Clinic researchers have safely transplanted cardiac preprogrammed embryonic stem cells into diseased hearts of mice successfully regenerating infarcted heart muscle without precipitating the growth of a cancerous tumor — which, so far, has impeded successful translation into practice of embryonic stem cell research.
MIT researchers have developed a technique to encourage the survival and growth of adult stem cells, a step that could help realize the therapeutic potential of such cells.
A team of scientists, led by psychiatric geneticists at Washington University School of Medicine in St. Louis, has gathered the most extensive evidence to date that a gene that activates signaling pathways in the brain influences one kind of intelligence. They have confirmed a link between the gene, CHRM2, and performance IQ.
The gene Sox17 is discovered to play a central role in the complicated dance of signals, enzymes and proteins that transform embryonic stem cells into a beating heart muscle cell.
Many doctors should change the way they prescribe pain relievers for chronic pain in patients with or at risk for heart disease based on accumulated evidence that nonsteroidal anti-inflammatory drugs (NSAIDs), with the exception of aspirin, increase risk for heart attack and stroke, according to an American Heart Association statement published in Circulation: Journal of the American Heart Association.
French CNRS researcher, with NIH, has identified the influence variation in the estrogen cycle has on the female brain. For the first time, scientists have identified the neural networks involved in processing reward-related functions modulated by female gonadal steroid hormones. This was published on the Proceedings of the National Academy of Sciences USA Web site Jan. 29, 2007.
Academics have found, for the first time, smells from healthy feces and people with infectious diarrhea differ significantly in their chemical composition and could be used to diagnose quickly diseases such as Clostridium difficile (C. Diff.).
