Between 1999 and 2006, the prevalence of adults in the U.S. with high levels of LDL cholesterol, the "bad" cholesterol, decreased by about one-third, according to a study in the November 18 issue of JAMA. But a high percentage of adults still are not being screened or treated for high cholesterol levels. http://www.physorg.com/news177703506.html Medicine & Health Tue, 17 Nov 2009 18:40:03 EST news177703506 (PhysOrg.com) -- For all the good it does, a liver protein that senses and gets rid of drugs and pollutants from our body has a downside. For the first time, it has been shown that when it is chronically activated, the protein, called PXR, rejiggers how cholesterol is processed in the liver and increases the risk of developing atherosclerosis. The work has direct clinical consequences to patients under long-term treatment of PXR-activating drugs, including several antibiotic and anti-cancer medications - and your daily latte. http://www.physorg.com/news176624554.html Medicine & Health Thu, 05 Nov 2009 06:50:02 EST news176624554 (PhysOrg.com) -- A drug that raises levels of 'good' cholesterol, when taken in addition to standard statin therapy to lower 'bad' cholesterol, can reduce the furring up of arteries in patients with established heart disease, an Oxford University study has shown. http://www.physorg.com/news176575852.html Medicine & Health Wed, 04 Nov 2009 16:51:20 EST news176575852 (AP) -- Working up a sweat may be even better than angioplasty for some heart patients, experts say. http://www.physorg.com/news170862819.html Medicine & Health Sun, 30 Aug 2009 14:54:06 EST news170862819 Health-conscious people know that high levels of total cholesterol and LDL cholesterol (the so-called "bad" cholesterol) can increase the risk of heart attacks. Now scientists are reporting that another form of cholesterol called oxycholesterol - virtually unknown to the public - may be the most serious cardiovascular health threat of all. http://www.physorg.com/news169978803.html Medicine & Health Thu, 20 Aug 2009 09:20:51 EST news169978803 Researchers at UT Southwestern Medical Center have found that a protein responsible for regulating "bad" cholesterol in the blood works almost exclusively outside cells, providing clues for the development of therapies to block the protein's disruptive actions. http://www.physorg.com/news159170000.html Chemistry Fri, 17 Apr 2009 06:53:48 EST news159170000 (AP) -- Statin drugs, taken by millions of Americans to lower cholesterol and prevent heart disease, also can cut the risk of developing dangerous blood clots that can lodge in the legs or lungs, a major study suggests. http://www.physorg.com/news157559982.html Medicine & Health Sun, 29 Mar 2009 15:40:18 EST news157559982 (PhysOrg.com) -- To prolong the shelf life of foods, manufacturers often add hydrogen to natural oils, a process called hydrogenation. But hydrogenation also results in the production of trans fats, which have adverse health effects such as raising bad cholesterol and increasing the risk for coronary heart disorders. http://www.physorg.com/news151936292.html Chemistry Fri, 23 Jan 2009 12:32:25 EST news151936292 A study performed by the team of Dr. Nabil G. Seidah, Director of the Biochemical Neuroendocrinology Research Unit at the IRCM, shows for the very first time that the degradation by PCSK9 of the LDLR receptor, which is responsible for removing the bad cholesterol (LDL-cholesterol) from the bloodstream, may be inhibited by a third protein, annexin A2. This major discovery co-authored by Gaétan Mayer, a postdoctoral fellow, Steve Poirier, a doctoral student, and Dr. Seidah was published on November 14 in the Journal of Biological Chemistry. http://www.physorg.com/news146746051.html Chemistry Mon, 24 Nov 2008 10:47:31 EST news146746051
