Background & Aims: The present study deals with an investigation on the effect of iron deficiency anemia and iron supplementation on anemia markers and plasma lipid profiles in pregnant women. Methods: A total of 350 pregnant women were taken and divided into four groups on the basis of haemoglobin levels viz. control (100), mild (100), moderate (100) and severe (50) patients. All the groups we...

The monocyte/macrophage appears to be the precursor of many of the lipid-laden cells in atherosclerotic lesions, but the mechanism by which these cells accumulate cholesterol to become foam cells remains unclear. We have previously reported that cultured endothelial cells can modify low density lipoprotein (LDL) in a manner that leads to rapid uptake by the acetyl LDL receptor of macrophages. T...

This study was conducted to determine the effects of a low polyunsaturated fatty acid (PUFA) 21 diet versus a highPUFA diet on lipid peroxidation and on low density and very low density lipoprotein (LDL + VLDL) oxidation in vivo. Rats were fed 10% beef tallow (BT) or 10% soybean oil (SO) diet for 21 weeks. Lipid peroxidation was measured by assessing urinary 24 excretions of secondary lipid per...

The influence of different plasma triglyceride concentrations on the heterogeneity of low density lipoprotein (LDL) and on the susceptibility of LDL to copper oxidation was investigated. By density gradient ultracentrifugation, LDL subfractions were isolated from the plasma of 10 normolipidemic control subjects and 12 hypertriglyceridemic patients both before and after clofibrate treatment. In ...

It has been well established that purified lipoprotein lipase (LPL) can facilitate the cellular uptake of various native and modified lipoproteins when added exogenously to macrophages. Because activated macrophages express LPL endogenously, it was the aim of this study to investigate the effect of macrophage-produced LPL on the uptake of native low-density lipoprotein (LDL) and LDL that has be...

The UV-visible results of this kinetic study show that amphothericin B as Fungizone is a much stronger oxidant than CuSO(4), itself a powerful oxidant of low-density lipoprotein (LDL). Amphotericin B as AmBisome alone has no oxidizing effect on LDL while a mixture of both AmBisome and CuSO(4) induces an important potentialization of the LDL oxidation. These results allow us to believe that the ...

OBJECTIVE Oxidized low-density lipoprotein (Ox-LDL)is implicated in the pathogenesis of atherosclerosis. Circulating oxidation-specific epitopes on plasma Ox-LDL has been linked with coronary artery disease, but its determinants and its association with early development of atherosclerosis in familial combined hyperlipidemia (FCHL) has not been very well studied. This study aimed to investigate...

OBJECTIVE Because of the large variation in oxidizing procedures and susceptibility to oxidation of low-density lipoprotein (LDL) and the lack in quantification of LDL oxidation, the role of oxidation in LDL-platelet contact has remained elusive. This study aims to compare platelet activation by native LDL (nLDL) and oxidized LDL (oxLDL). METHODS AND RESULTS After isolation, nLDL was dialyzed...

Apolipoprotein A-I (apoA-I) and an apoA-I peptide mimetic removed seeding molecules from human low density lipoprotein (LDL) and rendered the LDL resistant to oxidation by human artery wall cells. The apoA-I-associated seeding molecules included hydroperoxyoctadecadienoic acid (HPODE) and hydroperoxyeicosatetraenoic acid (HPETE). LDL from mice genetically susceptible to fatty streak lesion form...
