CONTEXT Apolipoprotein (apo) C-III is associated with hypertriglyceridemia and progression of cardiovascular disease. Plasma apoC-III is elevated in centrally obese men, and we hypothesized that the kinetics of apoC-III are disturbed in these subjects. OBJECTIVE We developed a compartmental model to determine very low-density lipoprotein (VLDL) and high-density lipoprotein (HDL) apoC-III meta...

To explore the protective effect of sesame seed oil (SSO) extracted from Til-06 variety in Sprague-Dawley male rats against management hypercholesterolemia, current two-phase study was conducted. In first phase, taken out seeds (Til-06) and physicochemical analysis carried to find content following by evaluation quality attributes oil. second efficacy check hyperlipidemic activity Randomly dist...

To study the mechanisms of discrimination between various forms of vitamin E, four normal subjects, one patient with lipoprotein lipase deficiency, and three patients with abnormal apolipoprotein B-100 production were given an oral dose containing three tocopherols labeled with differing amounts of deuterium (2R,4'R,8'R-alpha-(5,7-(C2H3)2)tocopheryl acetate (d6-RRR-alpha-tocopheryl acetate), 2S...

Metabolism of very low density lipoproteins (VLDL) has been compared in fat (FL) and lean (LL) lines of chicken. When refed after fasting, plasma triglyceride concentration reached a significantly higher plateau in FL, although their feed consumption was lower than in LL. Newly synthesized VLDL were studied using anti-lipoprotein lipase antibodies. VLDL triglyceride (TG) concentrations were inc...

Very low density lipoproteins (VLDL), Sf60 to 400, from normolipemic individuals do not suppress 3-hydroxy-3-methylglutaryl-CoA reductase activity in cultured normal human fibroblasts at concentrations 20fold higher than those of low density lipoproteins (LDL) that give total suppression. To determine if these VLDL contain all of the structural elements necessary for receptor-mediated suppressi...

fl-Migrating very-low-density lipoprotein (fl-VLDL) is a cholesteryl-ester-enriched lipoprotein which under normal conditions is rapidly cleared by parenchymal liver cells. In this study the characteristics of the interaction of,6-VLDL with rat parenchymal cells, Hep G2 cells and human parenchymal cells are evaluated. The binding of fl-VLDL to these cells follows saturation kinetics (Bmax respe...

The aim of this work was to determine the effect of dietary n - 3 PUFA on oxidant/antioxidant status, in vitro very low and low density lipoprotein (VLDL-LDL), and VLDL-LDL-fatty acid composition in macrosomic pups of diabetic mothers. We hypothesized that n - 3 PUFA would improve oxidative stress in macrosomia. Diabetes was induced in female Wistar rats fed with the ISIO diet (control) or with...

The production and catabolism of very low density lipoprotein triglycerides (VLDL-TG) were determined in 11 index patients with primary hypertriglyceridemia and in their 70 first-degree relatives. In the probands the mean value for VLDL-TG production rate was twice normal, and the mean fractional catabolic rate (FCR) was reduced to 50% from normal. A similar kinetic pattern was also observed in...

High plasma levels of VLDL are associated with increased risk for atherosclerosis. Here we show that VLDL (75 to 150 microg/mL) activates nuclear factor-kappaB (NF-kappaB), a transcription factor known to play a key role in regulation of inflammation. Oxidation of VLDL reduced its capacity to activate NF-kappaB in vitro, whereas free fatty acids such as linoleic and oleic acid activated NF-kapp...
