Vitamin D may be an important way to arm the immune system against disorders like the common cold, report investigators from the University of Colorado Denver (UC Denver) School of Medicine, Massachusetts General Hospital (MGH) and Children's Hospital Boston. http://www.physorg.com/news154630523.html Medicine & Health Mon, 23 Feb 2009 16:56:22 EST news154630523 For more than 40 years, the prevailing explanation of why we get old has been tied to what is called oxidative stress. This theory postulates that when molecules like free radicals, oxygen ions and peroxides build up in cells, they overwhelm the cells` ability to repair the damage they cause, and the cells age. http://www.physorg.com/news154117063.html Biology Tue, 17 Feb 2009 18:18:36 EST news154117063 A research project at Rice University has brought scientists to the brink of comprehending a long-standing medical mystery that may link cardiovascular disease, osteoporosis and perhaps even Alzheimer's disease. http://www.physorg.com/news154100968.html Medicine & Health Tue, 17 Feb 2009 13:49:53 EST news154100968 (PhysOrg.com) -- You may be wondering at this point whether to toss those vitamins into your mouth or into the trash. That's not surprising since several recent reports have called the value of vitamins into question, leaving people to wonder if it's time to ditch their supplements all together. http://www.physorg.com/news154023079.html Medicine & Health Mon, 16 Feb 2009 16:12:00 EST news154023079 Arab-American women living in southeast Detroit whose conservative dress limits their exposure to sun should be taking a vitamin D supplement to boost their dangerously low serum levels, according to a study published by Henry Ford Hospital researchers. http://www.physorg.com/news153993030.html Medicine & Health Mon, 16 Feb 2009 07:51:14 EST news153993030 (PhysOrg.com) -- Plants, algae, and cyanobacteria (blue-green algae) are masters of everything to do with solar energy because they are able to almost completely transform captured sunlight into chemical energy. This is in part because the electrons set free by the photons are transported out of the `light receptor` 1:1 to be used as the driving force for chemical reactions. http://www.physorg.com/news153556173.html Chemistry Wed, 11 Feb 2009 06:33:12 EST news153556173 If you're like many Americans, your blood pressure has crept up as you've gotten older. But it doesn't have to. Our lifestyle has an impact on blood pressure; in fact, in parts of the world where people still live as their ancestors did, high blood pressure is rare. Things that contribute to a healthy blood pressure include a diet high in fruits and vegetables. http://www.physorg.com/news153148136.html Medicine & Health Fri, 06 Feb 2009 13:09:30 EST news153148136 Researchers have found evidence that a direct interaction between vitamin D and a common genetic variant alters the risk of developing multiple sclerosis (MS).
