Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists at The Wistar Institute have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues. In recorded experiments, immune cells called T cells can be seen actively migrating though tissues, making direct contact with tumor cells, and killing them.
Researchers at the Stanford University School of Medicine discovered that when a molecule responsible for dialing down the immune system malfunctions in the brain cells of mice, the rodents develop symptoms of the degenerative brain disease.
Cincinnati scientists have found further evidence that certain defensive white cells in the body cause or play a major role in the symptoms experienced by asthma patients.
A newly described virus is not a cause of Kawasaki disease, according to an article by a group of researchers in Denver, Colorado. Their article appears in the December 15 issue of the Journal of Infectious Diseases, now available online.
Researchers at the Texas Agricultural Experiment Station used RNAi to reduce the toxic compound gossypol from cottonseed to a level that is considered safe for consumption, but left the compound in the rest of the plant to ward off insects and disease. Once commercialized, seed from these plants could provide a new, high-protein food available to 500 million people a year.
Hearty feasts and couch-potato marathons are holiday traditions, but UT Southwestern Medical Center experts warn that packing on pounds and not exercising could be deadly for the 6 million Americans who have diabetes and don’t even know it.
Males experience more traumatic events on average than do females, yet females are more likely to meet diagnostic criteria for Posttraumatic Stress Disorder (PTSD), according to a review of 25 years of research reported in the November issue of Psychological Bulletin, published by the American Psychological Association (APA).
Important information will be presented regarding target blood hemoglobin concentrations and clinical outcomes in patients with chronic kidney disease during a session at the American Society of Nephrology’s 39th Annual Meeting and Scientific Exposition in San Diego, CA on Saturday, November 18.
A structured exercise program can boost the physical well-being of sedentary seniors who show early signs of losing independent function. The results hold promise that many older adults can lower their risk of major walking disability, according to researchers from Wake Forest University Baptist Medical Center and colleagues.
New research at Wake Forest University School of Medicine suggests that certain inhaled asthma medications ? as well as similar chemicals our bodies produce during times of high stress ? may worsen diseases such as asthma, heart failure and lupus that involve inflammation.
