Oxidation diminishes HDL's 'goodness.' (high-density lipoproteins, the 'good' lipoproteins)Atherosclerosis begins when "foam cells" rich in lipids (mostly cholesterol) accumulate along artery walls. Researchers at the University of California, San Diego UCSD is consistently ranked among the top ten public universities for undergraduate education in the United States by U.S. News & World Report.[3] It is a Public Ivy. [1] For graduate studies, most of UCSD's Ph.D. , showed that when a buildup of reactive molecules in the body causes low-density lipoproteins (LDLs) to undergo a chemical transformation known as oxidation, macrophages -- cells that help LDLs unload their cholesterol -- change into foam cells (SN: 4/30/88, p.279). Ordinarily, HDLs -- the so called "good" lipoproteins -- can withdraw cholesterol from foam cells and target it for removal from the body. But researchers at Kyoto University in Japan have now demonstrated that oxidized oxidized having been modified by the process of oxidation. oxidized cellulose see absorbable cellulose. HDLs lose much of their ability to do this. The new data "suggest that oxidative modification of 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. may stimulate development of atherosclerosis" by limiting its removal of cholesterol from faom cells, report Yutaka Nagano and his colleagues in the Aug. 1 PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES The Proceedings of the National Academy of Sciences of the United States of America, usually referred to as PNAS, is the official journal of the United States National Academy of Sciences. . |
