HIV Vaccine Trial Breaks Ground For Future Research
The results of the world's first phase 3 HIV vaccine efficacy trial are reported in the March 1 issue of The Journal of Infectious Diseases, now available online. Although the vaccine was ineffective in preventing HIV infection, the trial represents a landmark in the fight against HIV and offers the scientific community a foundation on which to build future trials. Pinpointing The Cause Of A Neurodegenerative Disorder
Howard Hughes Medical Institute researchers have discovered how the abnormal repetition of a genetic sequence can have disastrous consequences that lead to the death of neurons that govern balance and motor coordination. The studies bolster the emerging theory that neurodegenerative disorders can be caused by having extra copies of a normal protein, not just a mutated one. Protein That Promotes Survival Of Stem Cells Might Be Key To Poor Leuk
The complex and life-sustaining series of steps by which hematopoietic stem cells (HSC) give rise to all of the body's red and white blood cells and platelets has now been discovered to depend in large part on a single protein called Mcl-1. Study Provides New Insights Into Brain Organization
Scientists have provided new insights into how and why the brain is organized -- knowledge which could eventually inform diagnosis of and treatments for conditions like Alzheimer's disease and autism. The team, at Newcastle University and the International University Bremen, Germany, debunked a prevailing theory that the nervous system should have mainly very short nerve fiber connections between nerve cells, or neurons, to function at its most effective. Researchers Identify Key Step In Cocaine-induced Heart Enlargement, Su
Cocaine, in concentrations commonly sold on the street, causes the abnormal buildup of primitive proteins in heart muscle -- a process that can ultimately lead to sudden death, a new study reports. DNA of Jesus-era shrouded man in Jerusalem reveals earliest case of le
The DNA of a 1st century shrouded man found in a tomb on the edge of the Old City of Jerusalem has revealed the earliest proven case of leprosy. Patients With Cirrhosis And Impaired Cognitive Abilities Have More Mot
A recent study found that patients with cirrhosis of the liver who developed minimal hepatic encephalopathy (MHE) had a 16% rate of motor vehicle crashes compared to only 4% of those without MHE over one year. The rate of accidents was also significantly higher than the state annual crash rate of 3%-3.3%. Unhappy New Year for Auto Execs
Incoming lawmakers, bent on pushing increased fuel efficiency and punishing oil companies, could make 2007 a bumpy ride for automakers. In Autopia. Cows, Now Without Prions
Scientists engineer bovines resistant to mad cow disease. But carnivores can't rest easy just yet. In Bodyhack. Tuberculosis good and bad news: Blood pressure drug shows promise, but
Two new tuberculosis studies provide good news and bad news about the bacterium that infects nearly a third of the world's population and a disease that kills nearly 2 million people each year. The good news: A type of blood pressure medication shows promise at overcoming some drug-resistant tuberculosis, at least in the laboratory. The bad news: The Mycobacterium tuberculosis bacterium, which causes the disease, might be resistant to treatment in more people than previously thought.
