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 ...

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.

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.

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.

Cholesterol plays a variety of significant roles in biological systems. However, the mechanisms by which cholesterol functions remain largely unclear. The enantiomer of cholesterol (ent-cholesterol)--which has identical physical properties, but opposite three-dimensional configuration compared to cholesterol--is a unique tool that can be used to better

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 Δ7-cholestenol (lathosterol), possibly in the matrix.

This is a histological and biochemical study of cholesterol in the middle ear in various chronic otitis media syndromes of 22 cholesteatomatous temporal bones and 52 bioptic specimens. Only three of the temporal bones and 11 surgical specimens showed cholesterol crystals, all of which were in the granulation tissue surrounding the cholesteatoma and ...

.ur current model for cholesterol transport is summarized in Figure 10. In this figure we have put together the various steps in cholesterol transport that were described previously in this review. Under normal conditions, cholesterol metabolism and transport are well regulated.
