Omega-3 fatty acids linked to decreased risk of type 1 diabetes

Preliminary research suggests that in children at increased risk for type 1 diabetes, dietary intake of omega-3 fatty acids was associated with a reduced risk of pancreatic islet autoimmunity, which is linked to the development of diabetes, according to an article in the Sept. 26 issue of JAMA.

Some cancer cells mimic stem cells to evade chemotherapy

Anti-cancer treatments often effectively shrink the size of tumors, but some might have an opposite effect, actually expanding the small population of cancer stem cells believed to drive the disease, according to findings presented Sept. 19 by Vasyl Vasko, M.D. Ph.D., a pathologist at the Uniformed Services University of the Health Sciences (USU) at the American Association for Cancer Research's second International Conference on Molecular Diagnostics in Cancer Therapeutic Development.
