How Insulin Secreting Cells Maintain Their Glucose Sensitivity
Scientists have now disclosed the mystery how the insulin-secreting cells maintain an appropriate number of ATP sensing ion channel proteins on their surface. This mechanism explains how the human body can keep the blood glucose concentration within the normal range and thereby avoid the development of diabetes. Preventing Graft-versus-host Disease Disease After Bone Marrow Transpl
Most patients undergoing bone-marrow transplant must receive powerful chemotherapy drugs to suppress their immune system and prevent their bodies from rejecting the donated cells. New research shows that this chemotherapy increases the risk for graft-versus-host disease -- but also suggests that this risk can be reduced by replacing a natural antibiotic that's depleted when patients undergo chemotherapy. A multicenter study led by Children's Hospital Boston and the Dana-Farber Cancer Institute is about to test this idea. Once-a-day Epilepsy Drug Is Effective For Partial Seizures, Study Sugg
The epilepsy drug lamotrigine is effective in controlling partial seizures when taken once a day as an added therapy, according to a new study. The study involved 239 people from the United States and several other countries. New Class Of Antibiotics Effective Against Drug-resistant Bacteria Dis
A peptide identified in a fungus found in northern European pine forests possesses as much power as penicillin or vancomycin, according to an international team of researchers including Michael Zasloff, M.D., Ph.D. of Georgetown University Medical Center and Robert Lehrer, M.D. of the David Geffen School of Medicine at UCLA, both highly respected antimicrobial peptides researchers. The researchers isolated "plectasin,"the first defensin ever found in fungi. CU Researchers Find That Dopamine Is Key To Learning Likes And Dislike
For those who have wondered why they like or dislike certain things, or how they decide what to order from a menu, a team of researchers at the University of Colorado at Boulder says it's dopamine. Explosions In Space May Have Initiated Ancient Extinction On Earth
Scientists at NASA and the University of Kansas say that a mass extinction on Earth hundreds of millions of years ago could have been triggered by a star explosion called a gamma-ray burst. The scientists do not have direct evidence that such a burst activated the ancient extinction. The strength of their work is their atmospheric modeling -- essentially a "what if"scenario. Consumer and Media Alert: The Small Print That's Devastating Major Con
This 2003 article discusses the use of mandatory arbitration clauses (which preclude a resort to a court of law) to govern the resolution of disputes arising under many types of consumer contracts. The article notes that such clauses may appear in "loans, phone bills, home construction and repair contracts, stock brokerage agreements, pest-control contracts, bank depositors' agreements, college loans, mobile home purchases, [and] employment agreements."From the National Consumer Law Center (NCLC). Toward A Faster Prenatal Test For Down Syndrome
Scientists are reporting an advance toward rapid testing for prenatal detection of Down syndrome and other birth defects that involve an abnormal number of chromosomes. The test has the potential for producing results for worried parents within two hours rather than the two weeks required with existing tests. The Lopsided Brain: Attention Bias Is Shared By Humans And Birds
During some tasks humans have a tendency to devote more visual attention to the left side than the right, a phenomenon known as pseudoneglect. Researchers now report that pseudoneglect is not restricted to humans but is shared by birds, suggesting not only that brain structures thought to play a requisite role in pseudoneglect may not actually be essential for this phenomenon, but also that pseudoneglect may reflect evolutionary adaptations that allow animals to devote attention to multiple aspects of their environment. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community...
