Researchers at the University of Michigan have determined how the hormone leptin, an important regulator of metabolism and body weight, interacts with a key receptor in the brain. Leptin is a hormone secreted by fat tissue that has been of interest for researchers in obesity and Type 2 diabetes since it was discovered in 1995.

Comparative effectiveness research conducted over the past decade has had a limited impact on the way medical care is delivered, but many opportunities exist to help doctors and others in the medical system translate such research into better patient care, according to a new RAND Corporation study.

Three thousand new cases of Mantle Cell Lymphoma (MCL), a form of blood cancer, appear in the United States each year. With a median survival span of only five to seven years, according to the Leukemia and Lymphoma Society, this disease is devastating, and new therapies are sorely needed.

New research shows that women who regularly use pain relief medications, particularly aspirin, have a decreased risk of serous ovarian cancer - an aggressive carcinoma affecting the surface of the ovary. The study published in Acta Obstetricia et Gynecologica Scandinavica reports that non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs), paracetamol (acetaminophen), or other analgesics did not decrease ovarian cancer risk.

An older medication originally approved to treat heart problems eases the symptoms of a very rare muscle disease that often leaves its sufferers stiff and in a good deal of pain, physicians and researchers report in the Journal of the American Medical Association.

Scientists at USC have discovered a new type of drug for the treatment of ovarian cancer that works in a way that should not only decrease the number of doses that patients need to take, but also may make it effective for patients whose cancer has become drug-resistant.

A new type of antibiotic can effectively treat an antibiotic-resistant infection by disarming instead of killing the bacteria that cause it. Researchers report their findings in the October 2 issue of mBio®, the online open-access journal of the American Society for Microbiology.
