background: to evaluate the association of apolipoprotein b (apob), apolipoprotein a (apoa), and apob/apoa ratio with the body fat indicators in patients with stable angina pectoris (sa). materials and methods: one hundred and twenty two participants aged 40-60 years old, with a mean age of 52.1 ± 7.2 years and sa, were recruited for the present study. body weight, height, and waist circumferen...

Diabetes mellitus is the most common endocrine disorder, causes many complications such as micro- and macro-vascular diseases. Anti-diabetic, hypolipidemic and anti-oxidative properties of ginger have been noticed in several researches. The present study was conducted to investigate the effects of ginger on fasting blood sugar, Hemoglobin A1c, apolipoprotein B, apolipoprotein A-I, and malondial...

The overproduction of very-low-density lipoprotein (VLDL) is a characteristic feature of nonalcoholic fatty liver disease (NAFLD). The aim of this study was to use a high-fat diet-induced model of NAFLD in rats to investigate 1) the influence of the disease on hepatic VLDL processing in the endoplasmic reticulum and 2) the potential modulatory effects of dietary coenzyme Q (CoQ). Rats were fed ...

By means of a combination of ion-exchange and sequence-specific affinity chromatography techniques, we have purified to homogeneity two protein complexes binding in a human DNA region (B48) previously recognized to contain a DNA replication origin. The DNA sequence used for the protein purification (B48 binding site) contains a binding site for basic-helix-loop-helix DNA binding proteins. The f...

OBJECTIVE The arterial retention of apolipoprotein (apo) B100- and apoB48-containing lipoproteins was simultaneously determined in a rabbit model of human hypercholesterolemia using 3D confocal microscopy. METHODS AND RESULTS Lipoproteins containing apoB100 (LDL) and apoB48 (chylomicron remnants) were differentially conjugated with fluorophores and simultaneously perfused at equivalent concen...

AIM Clinical trials suggest that residual risks remain for coronary artery disease (CAD) during low-density lipoprotein cholesterol (LDL-C) lowering therapy. We aimed to investigate the role of exogenous lipids in the prognosis of CAD after percutaneous coronary intervention (PCI). METHODS A total of 145 patients with CAD, who underwent elective PCI, and 82 non-CAD (control) patients were enr...

The present research was undertaken to determine the effects of EPA (20 : 5 n-3) and DHA (22 : 6 n-3) on chylomicron and VLDL synthesis and secretion by Caco-2 cells. Cells were incubated for 12 to 36 h with 400  μM OA, EPA, and DHA; then 36 h was chosen for further study because EPA and DHA decreased de novo triglycerides synthesis in a longer incubation compared with OA  (P < 0.01). Neither t...

BACKGROUND & AIMS Excessive postprandial lipemia is a prevalent condition that results from intestinal oversecretion of apolipoprotein B48 (apoB48)-containing lipoproteins. Glucagon-like peptide-2 (GLP-2) is a gastrointestinal-derived intestinotropic hormone that links nutrient absorption to intestinal structure and function. We investigated the effects of GLP-2 on intestinal lipid absorption a...

The effect of endotoxin on myocardial utilization of very low density lipoprotein (VLDL) triacylglycerol (TAG) was studied. VLDL was prepared by rat liver perfusion and tested as substrate in the isolated working rat heart. Both liver and heart donor rats were pretreated in vivo with endotoxin or vehicle (control). VLDL-TAG synthesized by endotoxin-pretreated livers was assimilated and oxidized...

Background and aims: When a high fat oral load is followed several hours later by further ingestion of nutrients, there is an early postprandial peak in plasma triacylglycerol (TG). The aim of this study was to investigate the location and release of lipid from within the gastrointestinal tract. Methods: Ten healthy patients undergoing oesopho-gastro-duodenoscopy (OGD) were recruited. At t=0, a...
