DURHAM, N.C., and New York, N.Y. -- Scientists at Duke University Medical School and Mount Sinai School of Medicine have found a new role for a host protein that provides further insight into how CD8+ T cells work to control HIV and other infections. Study authors say the finding may yield new strategies for prevention or treatment.

PASADENA, Calif.—The sepals of the plant Arabidopsis thaliana—commonly known as the mouse-eared cress—are characterized by an outer layer of cells that vary widely in their sizes, and are distributed in equally varied patterns and proportions.
A new "tree of life" has been constructed by researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech for the gamma-proteobacteria, a large group of medically and scientifically important bacteria that includes Escherichia coli, Salmonella typhimurium, and other disease-causing organisms.* By building powerful phylogenetic trees, scientists are able to quickly identify similarities and differences between the make-up of many different organisms, crucial information in the search for treatments to fight anything from the bugs that cause food poisoning to the pathogens that
PHILADELPHIA – Getting from point A to B may sound simple, but not so in the formation of fat cells.
ATS 2010, NEW ORLEANS— Neuromuscular electrical stimulation (NMES) may reduce muscle atrophy in patients with severe chronic obstructive pulmonary disease (COPD), according to Canadian researchers.
The results will be reported at the ATS 2010 International Conference in New Orleans.
ATS 2010, NEW ORLEANS— Human stem cells administered intravenously can restore alveolar epithelial tissue to a normal function in a novel ex vivo perfused human lung after E. coli endotoxin-induced acute lung injury (ALI), according to research from the University of California San Francisco.
The findings will be reported at the ATS 2010 International Conference in New Orleans.
Plant geneticists are on a determined quest — to control auxin, a powerful plant growth hormone. Auxin tells plants how to grow, where to lay down roots, how to make tissues, and how to respond to light and gravity. Knowing how to manipulate auxin could thus have enormous implications for the production of biofuel, making plants grow faster and better.
Despite fears to the contrary, the use of drugs to end life without patient request has not increased since euthanasia was legalized in Belgium, states an article in CMAJ (Canadian Medical Association Journal)http://www.cmaj.ca/cgi/rapidpdf/cmaj.091876v1?ijkey=7e8aeb7d487df3b7630863f09968fab81968bfdd (www.cmaj.ca).
The six-foot-long babies of the world's biggest shark species, Carcharocles megalodon, frolicked in the warm shallow waters of an ancient shark nursery in what is now Panama, report paleontologists working at the Smithsonian Tropical Research Institute and the University of Florida.
CHICAGO (May 17, 2010) – It's no secret that pregnancy is an important time in a woman's life. While women often hear about how pregnancy causes physical changes that affect their hormone or appetite levels, these changes can have a great effect on their oral health as well. Despite the fact that good oral health is essential for the overall health of both mother and child, only 22 to 34 percent of women in the United States visit a dentist during pregnancy.
New research discovers a combination of drugs that may prove to be a more effective treatment for a lethal form of leukemia. The study, published by Cell Press in the May issue of the journal Cancer Cell, reports that the new therapeutic strategy effectively targets notoriously intractable leukemia stem cells that often escape standard treatment and are a main factor in disease relapse.
Montreal, May 17, 2010 – A team of scientists from the University of Montreal and Harvard University have discovered that exposure to organophosphate pesticides is associated with increased risk of Attention-Deficit Hyperactivity Disorder (ADHD) in children.
What to do: walk around the block or work up a sweat in an aerobic workout at the gym? If you're looking for the best health benefits from an exercise program, a traditional aerobic fitness program that gets your heart pumping beats a walking program hands down. But if you want to get moving, a walking program is easier to do, it's good for you, and you're more likely to stick with it.
The Basque Institute for Agricultural Research and Development (Neiker-Tecnalia) has completed a study commissioned by the Department of the Environment, Land Use Planning, Agriculture and Fisheries of the Basque Government, in which individuals of various species of wild carnivores were investigated in order to know the types and frequencies of diseases affecting them. The study was restricted to the Basque Country and showed the presence of pathogens such as Salmonella, Yersinia, Toxoplasma, Trichinella and Sarcoptes.
