In medicine , LDL apheresis is a form of apheresis , resembling dialysis , to eliminate the cholesterol containing particle low density lipoprotein LDL from the bloodstream. Uses It is used in diseases featuring high LDL, such as the rare disease rare homozygous familial hypercholesterolemia , when the heterozygous form does not respond to medical treatment, or when the treatment has led to dangerous Adverse effect medicine side effects such as rhabdomyolysis . The procedure takes 2 4 hours and must be repeated every several weeks to keep the LDL levels from accumulation and causing cardiovascular disease . It is an expensive procedure, limiting its use to severe cases of hyperlipidemia . Principles LDL apheresis works by leading venous blood through a column coated with antibody antibodies to apolipoprotein B the main protein of LDL particles , dextran dextran sulfate sulfate or polyacrylate , or by precipitating LDL with heparin at low pH . In all cases apart from polyacrylate absorption , blood plasma plasma is separated from blood cell cells by a cell separator . References Thompson GR. LDL Apheresis . Atherosclerosis 2003 167 1 13.

Advert date August 2010 The VAP Vertical Auto Profile Test is a cholesterol , lipid and lipoprotein test. The name VAP Test was coined by the privately held cardio diagnostic company Atherotech ref http www.thevaptest.com ref to identify their direct measurement method which categorizes not just total cholesterol, High density lipoproteins HDL high density lipoproteins HDL , and low density lipoproteins LDL , but all lipids and subclasses, with an LDL measurement accuracy unaffected by triglycerides . Citation needed date December 2009 Atherotech claims their VAP Test has a unique ability to identify far more areas of risk to patients than the standard lipid panel, specifically because it reports 15 separate components versus four in the standard cholesterol test. The more comprehensive test was shown Citation needed date December 2009 to identify more than twice the number of patients with lipid abnormalities than the standard lipid panel cholesterol and triglyceride test . Unlike the standard lipid panel, the VAP Test directly measures LDL. The test is also the only commercially available test that meets the new American Diabetes Association and American College of Cardiology ADA ACC cholesterol guidelines for people at high risk of heart attack and stroke including people with Type 2 diabetes . The ADA ACC consensus statement establishes measurement and treatment guidelines for Apolipoprotein B apoB in addition to LDL and non HDL in high risk patients. The VAP Test is the first cholesterol profile to comply with updated National Cholesterol Education Program ATP III recommendations for LDL measurement and the only commercially available advanced lipid profile that routinely reports all three lipoprotein parameters considered necessary by the American Diabetes Association and American College of Cardiology expert consensus guidelines.

These are first hydrogenation hydrogenated to give a plant stanol which is then ester ified with a mixture of fatty acid s also derived from plants. Plant stanol esters are found naturally occurring in small quantities in fruits, vegetables, nuts, seeds, cereals, legumes, and vegetable oils. Stanol ester is often added to rapeseed oil based margarine or other foods for its health benefits. Studies have indicated that consumption of about 2 grams per day provides a reduction in LDL cholesterol of about 10 . The compound itself passes through the Gut zoology gut without entering the blood stream or lymph . Its presence, however, reduces both the amount of cholesterol the body absorbs from food and the reabsorption of the cholesterol component of bile .

Image JeanPol Martin2002.jpg thumb 200px right Jean Pol Martin Jean Pol Martin born 1943, Paris , France is a teacher professor for foreign language teaching in Germany . He established the teaching method Lernen durch Lehren learning by teaching , a method for students to learn by teaching their peers. This concept has developed into a common practice throughout Germany and has been experimented with in other countries. Biography Martin was born in 1943 in Paris and went to Germany in 1968. He studied German language German and French language French in order to become a teacher at a German grammar school , becoming a professor for foreign language teaching didactics at the http www.ku eichstaett.de Catholic University of Eichst tt Ingolstadt Bavaria in 1980. In the same year he had the idea to let the students teach their peers in his French classes. That experience was successful, so he could establish the Lernen durch Lehren LdL learning by teaching method in Germany. He was the first scholar to do active research on that topic for 30 years, building a wide network with several thousand teachers and promoting it to a large scale. All teachers in Germany are now trained in that method during their pedagogic studies. Martin retired 2008. References Grzega, Joachim Schoener, Marion.
