It has previously been shown that the hydrolysis of high density lipoprotein (HDL) phospholipids by hepatic lipase promotes the hepatic uptake of triglyceride and cholesteryl ester from HDL. Since the hydrolysis of HDL phospholipids promotes HDL cholesteryl ester uptake, then it is possible that the hepatic metabolism of HDL could be altered by changing the molecular species composition of HDL ...
The phagocytic index K, established from the rate of blood clearance of colloidal carbon, measures the phagocytic activity of RE macrophages in contact with the circulating blood. The intravenous injection of glyceryl trioleate (triolein) produces a marked stimulation of the phagocytic activity of RE macrophages. This response is higher in the female than in the male mice. The phenotypic charac...
An acid lipase was purified from rat liver lysosomes. Lipase purification involved affinity chromatography, gel filtration, and stabilization of the purified preparation using ethylene glycol and Triton X-100. A molecular weight of 67,000-69,000 was determined independently using density gradient centrifugation, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and gel filtration. To s...
BACKGROUND Triolein emulsion infusion into the brain produces transiently increased vascular permeability. OBJECTIVES The purpose of this study was to find the minimum percentage of triolein emulsion required for studying vascular permeability with minimal brain edema. MATERIALS AND METHODS Sixty healthy cats were divided into six groups according to the concentration of emulsified triolein...
Commercially supplied radioiodinated triolein has been shown by thin-layer chromatography and silicic acid column chromatography to contain impurities, consisting mainly of diglycerides and monoglycerides, but also a small amount of free fatty acid. The effect of these impurities on the radioiodinated triolein absorption test requires further investigation.
An important advance in aquatic ecotoxicology is the development and application of biomimetic sampling technology for hydrophobic contaminants. In this paper, accumulation kinetics of five organochlorinated pesticides, i.e. hexachlorobenzene, lindan, aldrin, heptachlor epoxide and 4,4'-DDT, by triolein-containing semipermeable membrane device (triolein-SPMD) and by fish (rainbow trout) were co...
In order to determine the role of hepatic lipase in the hepatic uptake and metabolism of high density lipoprotein (HDL) triglycerides, cholesteryl esters, and phospholipids, isolated rat livers were perfused with a reconstituted HDL (rHDL) radiolabeled with [3H]triolein and [14C]cholesteryl oleate or palmitoyl-[14C]linoleoyl phosphatidylcholine. A bolus of radiolabeled rHDL was injected into th...
The direct conversion of natural products to useful engineering materials is desirable from both economic and environmental considerations. We describe the synthesis properties 100 % oil-based epoxy resins generated three epoxidized oils. catalyst, tris(pentafluorophenyl)borane (B(C6F5)3) in toluene, allowed for controlled cationic polymerization at a very low concentration. Epoxidized oils (de...
Factors regulating the intestinal synthesis and secretion of apoA-IV are incompletely understood. Although it is known that apoA-IV is stimulated by dietary lipid, it is not known whether graded doses of triglyceride elicit graded responses in apoA-IV synthesis and secretion. We used the chronic intestinal lymph-fistula rat to examine the effect of graded levels of intestinal triglyceride trans...
