New research, published in the journal Genetics describes a laboratory test that allows scientists to evaluate large numbers of fruit fly genes for a possible role in the formation of plaque-like protein aggregates within cells. Those genes often have counterparts in humans, which might then be manipulated to stop or slow the formation of plaque-like protein aggregates, the hallmark of Huntington's and several other neurodegenerative diseases. http://phys.org/news193678933.html Medicine & Health Fri, 21 May 2010 17:10:01 EST news193678933 Researchers at two laboratories at NYU Langone Medical Center have collaborated to identify a tiny micro-RNA, miR-33, that regulates key genes involved in cellular cholesterol transport. The study, published online May 13, 2010 in Science, found that inhibitors of miR-33 may be beneficial because they could enhance cholesterol removal from tissues and raise levels of HDL -- shown in clinical trials to promote regression of human atherosclerotic plaques. This discovery could lead to the development of new treatments for atherosclerosis that would eliminate cholesterol accumulation in the artery wall. http://phys.org/news192977228.html Medicine & Health Thu, 13 May 2010 14:00:21 EST news192977228 The human mouth is home to an estimated 800 to 1,000 different kinds of bacteria. The warm and moist environment, along with hard tooth surfaces and soft tissues, prove to be optimal factors in boosting germ growth. Many of these bacteria are harmful and can form a film on teeth called "dental plaque," which causes cavities, gingivitis and eventually more severe kinds of gum disease. http://phys.org/news190380679.html Medicine & Health Tue, 13 Apr 2010 12:32:21 EST news190380679 New research shows that doing a simple ultrasound scan of the carotid artery significantly improves the prediction of heart disease, giving doctors a better clue of who is at high risk for a heart attack. http://phys.org/news189789340.html Medicine & Health Tue, 06 Apr 2010 16:50:01 EST news189789340 University of Washington (UW) researchers have gathered evidence that dangerous plaques in blood vessels can rupture by overproducing protein-digesting enzymes. Plaques are fat-laden rough spots in the otherwise smooth walls of arteries. When a plaque ruptures, blood accumulates inside of it, a process known as plaque hemorrhage. The plaque enlarges and artery-blocking clots can form. If the flow of oxygen-rich blood is restricted, a heart attack, stroke, or damage to other organs can occur. http://phys.org/news189110259.html Medicine & Health Mon, 29 Mar 2010 20:40:01 EST news189110259 A family history of Alzheimer's is one of the biggest risk factors for developing the memory-robbing disease, which affects more than 5 million Americans and is the most common form of senile dementia.
