Dietary cholesterol, membrane cholesterol and cholesterol synthesis
Biochimie, 1991After describing the main steps of cholesterol biosynthesis the author recalls that the cholesterogenesis rate is feedback-inhibited by dietary cholesterol and examines the various processes of modulation. Hydroxy-3-methylglutaryl (HMG) CoA reductase, the key rate-limiting enzyme, is a 97 kDa endoplasmic reticulum glycoprotein, anchored 7-fold in this ...

Cholesterol, cholesterol lowering, and endothelial function
Progress in Cardiovascular Diseases, 1998A strong relationship between hypercholesterolemia and atherosclerosis has been established through epidemiological, experimental, and clinical trial data. Traditional theories on the pathophysiology of this relationship involve the deposition, modification, and cellular uptake of cholesterol, and the release of inflammatory and growth factors ...

Cholesterol Crystals and the Formation of Cholesterol Gallstones
New England Journal of Medicine, 1980To examine the relation of cholesterol crystallization to the formation of gallstones, gallbladder bile was obtained by means of duodenal intubation in 54 patients (eight with asymptomatic gallstones) and from 17 patients undergoing cholecystectomy for cholelithiasis. Hepatic bile was obtained from nine patients with common-duct stones.

Cholesterol lowering, low cholesterol, and mortality
The American Journal of Cardiology, 1993Cholesterol lowering in both primary and secondary prevention has been clearly demonstrated to lower coronary morbidity and, in secondary prevention, to lower coronary mortality as well. Putative dangers of cholesterol lowering remain unproven. Population studies linking low cholesterol to noncoronary mortalities do not demonstrate cause-and-effect ...

Serum cholesterol and HDL cholesterol in childhood
Irish Journal of Medical Science, 1981Serum concentrations of total cholesterol and of HDL cholesterol have been measured in 170 Irish children, aged 1–12 years, attending hospital for conditions other than hyperlipidaemia. There were no significant differences between the sexes, or between fasting and non-fasting samples for either estimation.

Cholesterol Esterase: A Cholesterol Transfer Protein
Biochemistry, 1995Rat pancreatic cholesterol esterase was examined for its ability to effect sterol transfer between small unilamellar vesicle (SUV) preparations. Sterol exchange was determined using SUV composed of palmitoyloleoylphosphatidylcholine/sterol (65:35) with or without 10 mol % phosphatidylserine or phosphatidic acid.

Atherosclerosis, 1987
The relationships between the cholesterol content of the diet, plasma cholesterol concentration, cholesterol absorption, and cholesterol synthesis (measured indirectly by desmosterol suppression technique) are explored in groups of high- and low-responding rhesus monkeys fed diets containing 0.02, 0.15 and 0.75 mg cholesterol/kcal.

Another cholesterol hypothesis: Cholesterol as antioxidant
Free Radical Biology and Medicine, 1991Current emphasis on cholesterol as agency if not cause of human atherosclerosis and subsequent cardiovascular disease ignores the essentiality of cholesterol in life processes. Additionally ignored is the ubiquitous presence of low levels of oxidized cholesterol derivatives (oxysterols) in human blood and select tissues, oxysterols also implicated in ...

Cholesterol Metabolism in Cholesteatoma and Cholesterol Granuloma
Annals of Otology, Rhinology & Laryngology, 1984Based on biochemical and morphological studies, the significance of cholesterol in cholesteatoma and cholesterol granuloma is discussed. In cholesteatoma, cholesterol is synthesized through desmosterol and Δ 7 -cholestenol (lathosterol), possibly in the matrix.

Sphingolipids and cholesterol are two lipid partners on cellular membranes where they form specific microdomains, named lipid rafts, which mediate specific cell functions. Sphingomyelin (SM) is one of the major sphingolipids. SM and free cholesterol are also two key lipids on the monolayer of plasma lipoproteins, including chylomicron, very low-density
