Dietary fish oils, which are rich in omega-3 fatty acids, are known to produce a marked lowering of very low density lipoprotein (VLDL) triglyceride concentrations, but they have a less marked effect on low density lipoprotein (LDL) cholesterol. Our previous apolipoprotein (apo) B kinetic studies in miniature pigs demonstrated that conversion of VLDL apo B to LDL apo B accounted for 15% to 20% ...

The lipid substrate specificity of Manduca sexta lipid transfer particle (LTP) was examined in in vitro lipid transfer assays employing high density lipophorin and human low density lipoprotein (LDL) as donor/acceptor substrates. Unesterified cholesterol was found to exchange spontaneously between these substrate lipoproteins, and the extent of transfer/exchange was not affected by LTP. By cont...

C-reactive protein (CRP), the classical acute-phase protein, can bind phospholipids by virtue of its specific, calcium-dependent reactivity with phosphorylcholine residues. However, analysis of acute-phase serum by gel filtration and by density gradient ultracentrifugation showed that the CRP was in a free, uncomplexed form, despite the coexistent presence of the various classes of serum lipopr...

An analysis of plasma lipids and lipoprotein fractions was performed over the course of the annual ovarian cycle of the female turtle, Chrysemys picta. Determinations of total plasma triglycerides, cholesterol, vitellogenin and apolipoprotein A-I (apoA-I) were made. The lipid and protein composition of the lipoprotein fractions [very low density lipoprotein (VLDL), low density lipoprotein (LDL)...

We have previously shown that incubation of human macrophages with antigen-antibody complexes prepared with native human low density lipoprotein (LDL) and rabbit anti-LDL antibodies (LDL-ICs) results in an increased intracellular accumulation of cholesteryl esters (CEs) and induces a marked increase in the number of LDL receptors. To determine whether the increased CE accumulation in these cell...

OBJECTIVE There may be an association between a low serum cholesterol level and dissociative disorders. METHOD The subjects of the study were 16 patients with dissociative disorder and 16 normal comparison subjects (two men and 14 women in each group). Total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein, and very low density lipoprotein levels were compared. R...

Atherosclerosis was experimentally induced in New Zealand white rabbits by feeding a high cholesterol diet for 12 weeks for screening of drugs against atherosclerosis. After 12 weeks, blood was collected from ear vein for evaluation of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) levels, then the animals were sacrificed to coll...
