A high level of physical activity in women who smoked reduced their risk of developing lung cancer by 28 percent compared to smokers who did not exercise, an analysis of more than 36,000 women shows.
A new advanced magnetic resonance imaging technique developed at the University of Illinois at Chicago for the diagnosis of neurological problems, such as Chiari malformations, hydrocephalus and brain injury, will be evaluated for clinical use through a $1.4 million National Institutes of Health Bioengineering Research Partnership grant.
Memory training and other non-drug treatments may one day help older adults ward off declines in mental function, according to researchers from Wake Forest University School of Medicine in an editorial in the current issue of the Journal of the American Medical Association.
Researchers at the University of Southern California have discovered a direct link between loss of testosterone and the development of an Alzheimer’s-like disease in mice. They also discovered that testosterone treatment slows progression of the disease.The study, published in the Dec. 20 issue of the Journal of Neuroscience, predicts that testosterone-based hormone therapy may be useful in the treatment and prevention of Alzheimer?s disease in aging men.
How people might play the popular game show — whether they’d accept an offer for quick cash or hold out for the chance to win $1 million — probably has less to do with what?s inside each briefcase than what’s inside each contestant’s brain, suggests a study. While researchers didn’t study players of the game, their research in normal adults provides new insight about reward-based decision making and may have implications for understanding and treating addiction.
University of California, San Diego biologists have shown that the chemical language with which neurons communicate depends on the pattern of electrical activity in the developing nervous system. The findings suggest that modification of nerve activity could have potential as a treatment for a wide range of brain disorders.
Blood transfusions save the lives of millions of heart surgery patients and others each year. But a new study suggests that patients who receive transfusions during heart bypass surgery have a higher risk of developing potentially dangerous infections, and dying, after their operation.
Researchers at the University of Maryland School of Medicine in Baltimore will begin a clinical trial in January to test the first cell culture-based pandemic influenza vaccine to see if it will provide immunity faster and more reliably than a vaccine produced in eggs. The new study is also the first test in the United States of a whole virus vaccine for avian influenza, which could produce a stronger response by the immune system.
A study of settlement decisions in workers’ compensation claims for low back pain has found almost no relationship between the rating of the disability’s severity when the claim was settlement and reported pain and disability 21 months later.
Right now there’s no rapid way to diagnose sepsis, a fast-moving blood infection that is a leading cause of death in hospital intensive care units. New research at Washington University School of Medicine in St. Louis suggests that doctors one day could quickly distinguish sepsis from widespread non-infectious inflammation based on genetic profiles of patients’ blood.
