Simple new method detects contaminants in life-saving drug The blood-thinning drug heparin is highly effective when used to prevent and treat blood clots in veins, arteries and lungs, but earlier this year its reputation as a lifesaver was sullied when contaminated heparin products caused serious allergic reactions that led to a large number of deaths. view more (2008-11-18)
Preventing anemia is important to kidney disease patients' quality of life Maintaining sufficient red blood cell levels is important to the physical and mental health of patients with chronic kidney disease (CKD), according to a study appearing in the January 2009 issue of the Clinical Journal of the American Society Nephrology (CJASN). The findings indicate that... view more (2008-11-12)
Hormone shows promise in reversing Alzheimer's disease and stroke Saint Louis University researchers have identified a novel way of getting a potential treatment for Alzheimer's disease and stroke into the brain where it can do its work. view more (2008-11-12)
Hormones and brain activity: Kinsey Institute study sheds light on facial preferences Scientists have long known that women's preferences for masculine men change throughout their menstrual cycles. A new study from Indiana University's Kinsey Institute is the first to demonstrate differences in brain activity as women considered masculinized and feminized male faces and whether the... view more (2008-11-12)
Cancer drugs my build and not tear down blood vessels Scientists have thought that one way to foil a tumor from generating blood vessels to feed its growth - a process called angiogenesis - was by creating drugs aimed at stopping a key vessel growth-promoting protein. But now the opposite seems to be true. view more (2008-11-10)
Coping and copulation behavior may help calculate diabetes risk Discussion of a man's background, attitude, and sexual history isn't just the fodder of Sex and The City episodes - in the future, it could also be a way of evaluating his risk of diabetes. view more (2008-11-06)
Apelin hormone injections powerfully lower blood sugar By injecting a hormone produced by fat and other tissues into mice, researchers report in the November Cell Metabolism that they significantly lowered blood sugar levels in normal and obese mice. view more (2008-11-05)
Apelin to rescue diabetics Sugar is naturally present in the blood in the form of glucose and is stored in the liver or adipose tissue (fat) thanks to the action of insulin. Glucose is stored or directly used to ensure satisfactory function of the heart, brain and so on according to the body's demands. view more (2008-11-05)
Pregnancy disorder signals need to screen for heart disease, study shows High blood pressure experienced during pregnancy could be a woman's earliest warning that she is at risk of developing heart disease - the number one killer of Canadian women - says Queen's University professor of Obstetrics and Gynecology, Graeme Smith. view more (2008-11-05)
Nature study demonstrates that bacterial clotting depends on clustering Bacteria can directly cause human blood and plasma to clot-a process that was previously thought to have been lost during the course of vertebrate evolution, according to new research at the University of Chicago, National Institute of Allergy and Infectious Diseases, and Institut Pasteur in Paris.... view more (2008-11-03)
Stem cell therapies for heart disease -- 1 step closer New research from the University of Bristol brings stem cell therapies for heart disease one step closer.
