Researchers have discovered that a protein called ATM kinase, which plays a crucial role in repairing double-strand breaks in DNA, also helps prevent cells with this type of DNA damage from dividing, thereby blocking the passage of persistent DNA damage on to daughter cells.
Scientists from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), National Cancer Institute (NCI), and Integrative Bioinformatics Inc. have made an important discovery about the role of an enzyme called ataxia telangiectasia mutated protein (ATM) in the body?s ability to repair damaged DNA. NIAMS and NCI are part of the National Institutes of Health (NIH).
Scientists at the Scripps Research Institute have found that chronic abuse of the highly addictive drug methamphetamine may be an unrecognized risk factor in the development of a number of potentially serious cardiovascular disorders frequently reported by methamphetamine abusers.
Does air pollution have a bigger effect on the immune system of females than males? It did among mice exposed to ozone — a major component in air pollution that is known to negatively affect lung function — and then infected with pneumonia, as significantly more females died from the infection than males.
Echinacea, a medicinal herb, and other herbal echinacea supplements can reduce the risk of catching a coomon cold by 58 percent and the duration of colds by a day-and-a-half, confirmed by researchers.
It has long been known that eating potatoes is good for bowel health, but new research suggests that they may also have a beneficial effect on the whole immune system. Especially if eaten cold or in a potato salad, Anne Pichon reports in Chemistry & Industry, the magazine of the SCI.
Researchers at Children?s Hospital Boston report finding a new way to increase stem cells in blood, suggesting a possible treatment to help patients who undergo chemotherapy or bone marrow transplant for leukemia and other cancers recover their immune function more quickly.
Researchers at the University of California, San Diego (UCSD) Skaggs School of Pharmacy and Pharmaceutical Sciences have patented a strategy for developing a human vaccine to prevent against Human Cytomegalovirus (hCMV) infection and disease.
The genes that make up the immune system of the Aedes aegypti mosquito which transmits deadly viral diseases to humans have been identified in new research out today in Science.
amfAR, The Foundation for AIDS Research, will grant almost $1.2 million for 10 new research projects aimed at increasing understanding of the social and biological factors that influence the treatment of HIV/AIDS, Dr. Rowena Johnston, amfAR?s vice president of research.
