Background: Type II diabetes mellitus (DM) is characterized by insulin resistance such as glucose intolerance, dyslipidemia, and hypertension, results in an increased predisposition to atherosclerotic vascular disease. The present study was conducted evaluate fasting postprandial lipid profile diabetic patients. Materials & Methods: We put 80 type patients group I healthy subjects II. Parameter...
BACKGROUND Qualitative alterations of lipoproteins underlie the high incidence of atherosclerosis in diabetes. The objective of this study was to assess the impact of low-density lipoprotein (LDL) subfraction phenotype on the qualitative characteristics of LDL and high-density lipoprotein (HDL) in patients with type 2 diabetes. METHODS One hundred twenty two patients with type 2 diabetes in p...
BACKGROUND Discordance between measures of atherogenic lipoprotein particle number (apolipoprotein B [ApoB] and low-density lipoprotein [LDL] particle number by nuclear magnetic resonance spectroscopy [LDL-PNMR]) is not well understood. Appropriate treatment considerations in such cases are unclear. OBJECTIVES To assess discordance between apoB determined by immunoassay and LDL-PNMR in routin...
Macrophages possess a number of surface receptors that are capable of mediating the internalization of lipoproteins. The low-density lipoprotein (LDL) receptor of human monocyte macrophages recognizes apolipoprotein B-100 and apolipoprotein E and is rapidly regulated in response to changes in intracellular cholesterol levels. In contrast, in J774 macrophages LDL receptor regulation is defective...
BACKGROUND Alirocumab, a monoclonal antibody to proprotein convertase subtilisin/kexin type 9 (PCSK9), lowers plasma low-density lipoprotein (LDL) cholesterol and apolipoprotein B100 (apoB). Although studies in mice and cells have identified increased hepatic LDL receptors as the basis for LDL lowering by PCSK9 inhibitors, there have been no human studies characterizing the effects of PCSK9 inh...
In this report we compare the cord blood lipoproteins of a newborn boy homozygote who has low density lipoprotein (LDL) receptor-defective familial hypercholesterolemia (FH) with the lipoproteins from cord blood of normal newborns. Plasma LDL-cholesterol and apoprotein (Apo)B were 612 and 233 mg/dl (vs. 31+/-16 and 24+/-12 mg/dl, respectively, for normals, n = 21). LDL-cholesterol/ApoB ratio wa...
OBJECTIVE To determine mechanisms contributing to the altered lipoprotein profile associated with aging and menopause, apolipoprotein B-100 (apoB-100) and apoA-I kinetic behavior was assessed. METHODS AND RESULTS Eight premenopausal (25+/-3 years) and 16 postmenopausal (65+/-6 years) women consumed for 6 weeks a standardized Western diet, at the end of which a primed-constant infusion of deut...
The addition of bacterial lipopolysaccharide (LPS) from Escherichia coli 0111:B4 to human monocyte-macrophages cultured in serum results in suppression of scavenger receptor activity. The present studies were performed to examine if the effect on scavenger receptor activity was mediated by LPS alone or by LPS in association with lipoproteins. Radioiodinated LPS (125I-LPS) was added to human pla...
AIM To determine distribution, size, and phenotype of low density lipoprotein (LDL) subclasses and examine the influence of plasma lipid concentrations on lipoprotein particle size in both healthy population and patients with myocardial infarction. METHOD Nondenaturing gradient (3-31%) gel electrophoresis for lipoprotein separation was used to determine the distribution and size of LDL subcla...
Low-density lipoprotein (LDL) cholesterol concentration has been the prime index of cardiovascular disease risk and the main target for therapy. However, several lipoprotein ratios or "atherogenic indices" have been defined in an attempt to optimize the predictive capacity of the lipid profile. In this review, we summarize their pathophysiological aspects, and highlight the rationale for using ...
