BACKGROUND Myocardial infarction (MI) is a leading cause of death globally, but specific genetic variants that influence MI and MI risk factors have not been assessed on a global basis. METHODS AND RESULTS We included 8795 individuals of European, South Asian, Arab, Iranian, and Nepalese origin from the INTERHEART case-control study that genotyped 1536 single-nucleotide polymorphisms (SNPs) f...

Lipoprotein profiles in experimental hypercholesterolemia were studied using euthyroid and hypothyroid cholesterol-fed rats. In both groups, serum cholesterol concentration increased, but to a lesser extent in the cholesterol-fed euthyroid rats, with similar changes in distribution among lipoprotein fractions in both groups. Agarose electrophoresis of plasma and individual lipoprotein fractions...

Beta very low density lipoproteins (B-VLDL) from cholesterol-fed animals and from patients with Type III hyperlipoproteinemia are internalized by a receptor-mediated process in mouse macrophages. Once internalized, the cholesteryl esters of B-VLDL are hydrolyzed in lysosomes, and the released cholesterol is re-esterified, resulting in a massive accumulation of cholesteryl esters. In the present...

Fifty three patients of alcohol dependence were studied for lipid profile at Drug Dependence Treatment Centre, A.I.I.M.S. Statistically significant differences were observed on most of lipid profile indicators when compared to control group. Ratio of Apo A-I & Apo B appeared to be better indicator than Apo A1 or Apo B. The findings of the study are discussed in context of other studies from Ind...

The aim of this study was to determine the extent of accumulation of lipoprotein(a) [Lp(a)] in human arterial wall and to define its potential role in atherogenesis. Biopsies routinely taken from the ascending aorta of 107 patients undergoing aortocoronary bypass surgery were analyzed for lipid and lipoprotein parameters, which were then correlated to serum values. A significant positive correl...

This study examined apolipoprotein (apo) B metabolism in normolipemic subjects homozygous for the apo E2 (n = 4), apo E3 (n = 5), or apo E4 (n = 5) phenotype. Radioiodinated very low density lipoprotein (VLDL1) (ultracentrifuge flotation rate [Sf] 60-400) and VLDL2 (Sf 20-60) were injected into volunteers and the conversion of apo B was followed through intermediate density lipoprotein (IDL) to...

The apo B gene is expressed in the human heart and in the hearts of human apo B transgenic mice generated with large genomic clones spanning the human apo B gene. [35S]Methionine metabolic labeling experiments demonstrated that apo B100-containing lipoproteins are secreted by human heart tissue and by human apo B transgenic and nontransgenic mouse heart tissue. Density gradient analysis reveale...

Background/Aims Changes in lipid profiles in patients infected with hepatitis C virus (HCV) during direct-acting antiviral therapy have been reported in recent years. However, the clinical aspects of disturbed lipid metabolism in chronic HCV infection have not been fully elucidated. Methods Dynamic changes in serum total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) chole...
