Potential method for preventing type 1 diabetes discovered
Scientists at the University of Maryland School of Medicine in Baltimore have identified a way to prevent Type I diabetes in rats that are genetically prone to develop the disease. The discovery could one day lead to the prevention, and possibly to the treatment, of autoimmune diseases such as Type 1 diabetes, which affects more than one million people in the United States. The findings are published in the 22 February 2005 edition of the Proceedings of the National Academy of Sciences. more

OHSU scientists develop MRI approach to improve breast cancer detection
Researchers at Oregon Health & Science University's Advanced Imaging Research Center (AIRC) are developing a new imaging method that may provide a clearer diagnosis of breast cancer. The research is published in the latest issue of the journal Magnetic Resonance in Medicine. AIRC Director Charles Springer, Ph.D., is senior author, and AIRC Manager, Xin Li, Ph.D., is first author of the new paper, along with William Rooney, Ph.D., AIRC faculty. Professor Springer also holds appointments in OHSU's Cancer Institute and Department of Biomedical Engineering.  more

Twenty somethings with sleep apnea most likely to die
Should screening for sleep apnea – which medical experts say may have contributed to the recent death of NFL great Reggie White at 43 – be required for all men? According to a new study, men in their 20s need to be screened the most. That’s because men aged 20 to 29 with severe sleep apnea have 10 times the risk of dying from heart related ailments than their non sleep apnea peers in the general population, and a much higher risk than older men with sleep apnea. more


Scientists regenerate optic nerve for the first time
For the first time, scientists have regenerated a damaged optic nerve -- from the eye to the brain. This achievement, which occurred in laboratory mice and is described in the March 1, 2005 issue of the Journal of Cell Science, holds great promise for victims of diseases that destroy the optic nerve, and for sufferers of central nervous system injuries. “For us, this is a dream becoming reality,” says Dr. Dong Feng Chen, lead author of the study, assistant scientist at Schepens Eye Research Institute and an assistant professor of ophthalmology at Harvard Medical School. “This is the closest science has come to regenerating so many nerve fibers over a long distance to reach their targets and to repair a nerve previously considered irreparably damaged.”  more

Inpatient smoking cessation counseling is associated with early differences in mortality
Giving up smoking after a heart attack has been clearly associated with improvements in long-term patient survival, but how soon after myocardial infarction does smoking cessation begin to have positive effects? A study published in the current issue of The American Journal of Medicine indicates in-hospital cessation counseling following heart attacks is associated with better short-term survival. Counseling smokers to quit reduced their chances of dying in the first 30 days, 60 days and up to 1 year after their attacks.  more

Scientists replicate hepatitis C virus in laboratory
For the first time, scientists have replicated hepatitis C virus (HCV) in the laboratory. The ability to replicate HCV in cell culture will allow researchers to better study the life cycle and biology of this virus and to test potential antiviral compounds, which may lead to new therapies for the liver disease that results from infection with HCV. Scientists at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), one of the National Institutes of Health (NIH), conducted the study, which appears in the 15 February 2005 issue of Proceedings of the National Academy of Sciences (PNAS).  more

Mothers on the run: Despite more hours at work, there's always more to do at home
Dramatic changes in working patterns have taken place in the UK, particularly in the rise of women in employment. Three quarters of households now have dual incomes, but women still take responsibility for most of the housework, according to research funded by the Economic and Social Research Council. more
