Recent studies have demonstrated that elevated levels of cholesterol in the form of remnant-like particles (RLP-C) induce deterioration of endothelial function during the fasting state, but it is not known whether postprandial RLP-C elevation has the same effect. The objective of this study was to assess the effect of postprandial RLP-C elevation on endothelial function in 24 fasting normolipid...
Net mass transfer of lipids was measured in plasma from fasted, normolipidemic subjects. The plasma was incubated, and lipoproteins were subsequently separated by polyanion precipitation or density gradient ultracentrifugation. Total cholesterol, unesterified cholesterol, and triglycerides were measured in the isolated lipoprotein fractions. The rate of cholesterol esterification was measured s...
Studies have shown that phosphatidylinositol (PI) can stimulate reverse cholesterol transport by enhancing the flux of cholesterol into HDL and by promoting the transport of high density lipoprotein-cholesterol (HDL-C) to the liver and bile. The goal of this study was to determine the safety and therapeutic value of PI after oral administration to normolipidemic human subjects. We performed a r...
We investigated the influence of high sucrose diet (HSD) after 3 or 5 weeks of administration on paraoxonase 1 (PON1) activity in plasma of normolipidemic rats and the relationship between serum PON1 activity, triacylglycerides (TGs), HDL and total cholesterol vs. the control group of rats fed normal, control diet (CD). Because the data about the influence of gemfibrozil (GEM) on PON1 activity ...
Peroxisome proliferator-activated receptor delta (PPAR-delta) is a transcription factor implicated in metabolism and inflammation. The +294T/C polymorphism in the PPAR-delta gene is associated with risk of coronary artery disease (CAD) in dyslipidemic women and hypercholesterolemic men. Whether this polymorphism influences the risk of CAD in the absence of dyslipidemia was not known, so we inve...
High-density lipoprotein (HDL) levels were studied in 10 male patients with severe coronary atherosclerosis and in 10 well-matched controls. All subjects were normolipidemic, and the presence of a disease or other factor influencing HDL levels were excluded. Very low density lipoprotein and low-density lipoprotein levels were similar in both groups, but HDL concentration was significantly lower...
Serum cholesterol, low density lipoproteins (LDL), very low density lipoproteins (VLDL) and chylomicron levels were studied in 25 young patients (age 40 years or less) of non-embolic ischemic stroke of unknown aetiology. Fifteen patients were males and 10 were females. The prevalence of hyperlipidemia was found to be 60%. Frederickson's type IIb hyperlipoproteinemia was the commonest (32%) abno...
Small, dense, electronegative low density lipoprotein [LDL(-)] is increased in patients with familial hypercholesterolemia and diabetes, populations at increased risk for coronary artery disease. It is present to a lesser extent in normolipidemic subjects. The mechanistic link between small, dense LDL(-) and atherogenesis is not known. To begin to address this, we studied the composition and dy...
Atherogenic lipoproteins can cause endothelial dysfunction in the initial stage of atherogenesis. In our study we examined 134 patients with defined hyperlipoproteinemia (non-HDL cholesterol>4.1 mmol/l or triglycerides>2.5 mmol/l or taking any of lipid lowering drugs)--94 men and 40 women. The subgroup of controls of comparable age contained 54 normolipidemic individuals--30 men and 24 women. P...
We determined cholesteryl ester transfer activity in whole plasma and in lipoprotein-depleted plasma of normolipidemic subjects and of patients with severe high-density lipoprotein (HDL) deficiency: Tangier disease, lecithin:cholesterol acyltransferase (LCAT) deficiency, and "fish-eye" disease. Transfer rates in plasma were positively correlated (r = 0.950) with rates measured in the absence of...
