Apolipoprotein A-IV is a member of the apo A-I/C-III/A-IV gene cluster. In order to investigate its hypothetical coordinated regulation, an acute phase was induced in pigs by turpentine oil injection. The hepatic expression of the gene cluster as well as the plasma levels of apolipoproteins were monitored at different time periods. Furthermore, the involvement of the inflammatory mediators' int...

Total serum lipids, as well as apolipoproteins A-I (apo A-I) and B (apo B), were determined in 74 patients with chronic liver failure without cholestasis and in 82 normal subjects. The VLDL, LDL and HDL lipid fractions were reduced in the liver failure group by 36%, 24% and 46%, respectively (P < 0.001). Apolipoproteins A-I and B were also reduced by 26% and 25%, respectively (P < 0.001). Howev...

Objective: To evaluate various lipid, lipoprotein and apolipoprotein ratios among participants with without metabolic syndrome.&#x0D; Study Design: Comparative cross-sectional study.&#x0D; Place Duration of Study: Naval Hospital, Islamabad Pakistan, from Jan 2019 to Dec 2020.&#x0D; Methodology: We selected 164 patients syndrome. Metabolic syndrome was diagnosed as per “NCEP-defined criteria”. I...

This review assesses current knowledge of the clinical, genetic, and biochemical features of familial high density lipoprotein (HDL) deficiency syndromes. The focus is on HDL deficiency states occurring in the absence of severe hypertriglyceridemia or lecithin/cholesterol acyltransferase deficiency. Specific entities falling within this category include Tangier disease, familial HDL deficiency ...

Serum PGI2 stabilizing factor (PSF) was purified from human serum to a single protein with a molecular weight of 28,000 D by SDS-PAGE. Analyses of NH2-terminal sequence (32 residues), COOH-terminal sequence (3 residues) and the composition of amino acids disclosed its homology with human apolipoprotein A-I (Apo A-I), a major apolipoprotein of HDL. Apolipoprotein A-II, C-I, C-II, C-III, D and E,...

b a ckground:  to compare the oxidative stress (os) factors in obese and non- obese subjects with type 2 diabetes (t2d) and to evaluate the interaction between the apolipoprotein a-ii (apo a-ii) - 265t > c polymorphism and body mass index (bmi) on os factors. m ethods : in this comparative cross-sectional study, 21 diabetes centers in tehran, iran were studied. 180 patients with t2d were divide...

Oxidation of low-density lipoprotein (LDL) may promote atherosclerosis, whereas the reverse transport oxidized lipids by high-density (HDL) contribute to atheroprotection. To provide insights into associations lipid oxidation markers with subclasses at population level, we investigated HDL (oxHDLlipids) and LDL (oxLDLlipids) in a population-based cross-sectional study 1395 Finnish adults ages 2...

Dyslipidemia is found to be associated with the initiation and progression of diabetic retinopathy (DR). Modifications of lipoproteins by glycation and oxidation and the variations in the size distributions of lipoprotein particles are not reflected in conventional lipid profiles. This study was conducted to know if the measurements of apolipoprotein AI (apo AI) and apolipoprotein B (apo B) may...

Epidemiological studies have demonstrated that the risk of coronary artery disease (CAD) is increased in smokers but reduced in individuals with elevated plasma levels of high density lipoprotein cholesterol (HDL-C) and apolipoprotein (apo) A-I. In a sample of 315 men and women from Iceland, the mean levels of HDL-C and apo A-I in smokers were, respectively, 12% and 6% lower in men and 7% and 6...

The lipoprotein Lp(a), a major inherited risk factor for atherosclerosis, consists of a low density lipoprotein-like particle containing apolipoprotein B-100 plus the distinguishing component apolipoprotein(a) (apo(a)). Human apo(a) contains highly repeated domains related to plasminogen kringle four plus single kringle five and protease-like domains. Apo(a) is virtually confined to primates, a...
