BODY : FITNESS & EXERCISE ABUNDANT `GOOD' CHOLESTEROL SOMETIMES CAN BE BAD.Byline: Andrew Bowser Bowser may mean:
A high level of ``good'' cholesterol may not always be a good thing, New York New York, state, United States New York, Middle Atlantic state of the United States. It is bordered by Vermont, Massachusetts, Connecticut, and the Atlantic Ocean (E), New Jersey and Pennsylvania (S), Lakes Erie and Ontario and the Canadian province of researchers report. In a new study of 3,500 Japanese-American men living in Hawaii, 6 percent were found to have a defective gene that causes blood levels of high-density lipoprotein high-density lipoprotein n. Abbr. HDL A lipoprotein that contains relatively small amounts of cholesterol and triglycerides and is associated with a decreased risk of atherosclerosis and coronary artery disease. (HDL (Hardware Description Language) A language used to describe the functions of an electronic circuit for documentation, simulation or logic synthesis (or all three). Although many proprietary HDLs have been developed, Verilog and VHDL are the major standards. ) or ``good'' cholesterol to increase. But, ironically, the higher levels of HDL did not lower the men's risk of heart disease. Rather, their risk of heart disease increased nearly twofold, according to the study, published in the June 15 issue of the Journal of Clinical Investigation The Journal of Clinical Investigation (JCI or J Clin Invest) is a leading biomedical journal, which is radically different from many of its peers in having a high impact factor (in 2006, 15.754) and offering all its contents entirely free. . The reason is that the defective gene decreases the ability of HDL to rid the body of harmful cholesterol, said researcher Dr. Alan Tall, a professor of medicine at Columbia University in New York. The mutation is located in a gene that produces a protein called cholesteryl ester transfer protein (CETP CETP Cholesteryl Ester Transfer Protein CETP Certified Employee Training Program CETP Common Effluent Treatment Plant CETP China Energy Technology Program CETP Centre de Recherches en Physique de l'Environment Terrestre et Planetaire (French) ), according to the study. CETP generally helps the body eliminate bad cholesterol via the liver. But this process is interrupted when the CETP gene is defective. Men with the genetic mutation had, on average, 35 percent less of the specialized protein than men without the mutation, the researchers found. The finding that high HDL levels are not always beneficial indicates that ``the story of HDL being protective is oversold Oversold In technical analysis, it is a market in which the volume of selling that has occurred is greater than the fundamentals justify. Notes: It is the opposite of overbought. ,'' said Dr. Paul Thompson, director of preventive cardiology at the University of Pittsburgh. Doctors should ``put a lot of weight in family history'' when assessing a person's heart-disease risk, he said. ``Who you pick for your parents is probably the primary determinant of what is going to happen to you,'' he added. While genetics play a large role in determining who gets heart disease, the importance of contributing environmental factors should not be downplayed, said Dr. Margo Denke, an associate professor at the center for human nutrition at the University of Texas. |
