A study by researchers at the University of California, San Francisco has shown that hypertension, or high blood pressure, is a predictor of mortality among breast cancer patients, especially those who are African-American, and that hypertension accounts for approximately 30 percent of the survival disparity between African-American and white breast cancer patients. http://www.physorg.com/news155396954.html Medicine & Health Wed, 04 Mar 2009 13:49:34 EST news155396954 A new generation of cancer drugs designed to starve tumors of their blood supply - called "angiogenesis inhibitors"--succeeds at first, but then promotes more invasive cancer growth -sometimes with a higher incidence of metastases, according to a new study in animals. The research clarifies similar findings in other animal studies and is consistent with some early evidence from a small number of clinical trials with cancer patients. http://www.physorg.com/news155226687.html Medicine & Health Mon, 02 Mar 2009 14:31:54 EST news155226687 Researchers at the Gladstone Institute of Cardiovascular Disease (GICD) and the University of California, San Francisco have unraveled a complex signaling process that reveals how different types of cells interact to create a heart. It has long been known that heart muscle cells (cardiomyocytes) actively divide and expand in the embryo, but after birth this proliferative capacity is permanently lost. http://www.physorg.com/news154097092.html Biology Tue, 17 Feb 2009 12:45:34 EST news154097092 A new drug that blocks cancer's main source of growth has been created in the lab and proven effective in mice, scientists are reporting. It is now being readied for clinical trials in patients. http://www.physorg.com/news153473578.html Biology Tue, 10 Feb 2009 07:33:24 EST news153473578 Scientists have discovered a novel way by which a much-studied cancer-promoting gene accelerates the disease. The finding suggests a new strategy to halt cancer's progress. http://www.physorg.com/news152011468.html Medicine & Health Sat, 24 Jan 2009 09:24:57 EST news152011468 There are no sheep keeping Mari A. company at bedtime. Rather, she counts thoughts of layoffs, mortgage payments and plummeting stocks. Her insomnia started back in November, when the economy hit a critical low. Restless, she manages to fall asleep but wakes up in the middle of the night and is unable to drift back into a slumber. http://www.physorg.com/news150654506.html Medicine & Health Thu, 08 Jan 2009 16:28:26 EST news150654506
