Scientists at Duke University Medical Center have visualized in a living animal how cells use a critical biological process to dice and splice genetic material to create unique and varied proteins.
Black patients are more likely than white patients to prefer life-sustaining care when confronted with an incurable illness or serious mental and physical disabilities, according to a study by University of Rochester Medical Center researchers.
Magnets may interfere with the operation of pacemakers and implantable cardioverter defibrillators, according to a study published in the December 2006 edition of Heart Rhythm.
Scientists have discovered an unsuspected role for a gene known to be one of the best predictors of human breast cancer outcome.
Pregnant women who develop an infection of the placenta or nearby membranes in their first pregnancy have twice the risk of getting it in their second pregnancy, researchers at UT Southwestern Medical Center have found.
Northwestern University is launching an experimental program for young women who may be at risk to lose their ovarian function and fertility following treatment for cancer. In the program, a woman’s ovary is removed and frozen for possible future use. The long-term goal is to be able to extract and mature eggs from cryopreserved (frozen) ovarian tissues to initiate pregnancies once cancer treatment has been completed. Thus far, pregnancies resulting from this research are in mice.
Results from one of the largest HIV/AIDS treatment trials ever conducted show that a specific strategy of interrupting antiretroviral therapy more than doubles the risk of AIDS or death from any cause. In the study, the investigators used two predetermined levels of CD4+ T cells, the primary immune cell targeted by HIV, to guide them in respectively suspending or restarting the study participants on antiretroviral therapy.
Results from a brain-imaging study conducted at the U.S. Department of Energy’s Brookhaven National Laboratory in collaboration with Mount Sinai School of Medicine in New York indicate that levels of a brain protein proposed as a diagnostic marker for attention-deficit hyperactivity disorder (ADHD) are not positively correlated with the disease.
Researchers from the Johns Hopkins Bloomberg School of Public Health and the Center for Micronutrient Research at Annamalai University in India report that the consumption of milk fortified with specific micronutrients — zinc, iron, selenium, copper, vitamin A, vitamin C and vitamin E — significantly reduces diarrhea and acute lower respiratory illness among children in developing countries.
Scientists at Wake Forest University Baptist Medical Center and colleagues at four other medical centers have launched a $10 million multi-year study to identify genes that may contribute to early atherosclerosis.
