BACKGROUND Ossabaw miniature swine when fed a diet high in fructose, saturated fat and cholesterol (NASH diet) develop metabolic syndrome and nonalcoholic steatohepatitis (NASH) characterized by liver injury and fibrosis. This study was conducted to further characterize the development of NASH in this large animal model. METHODS Ossabaw swine were fed standard chow (control group; n = 6) or N...

To compare endogenous cholesterol biosynthesis measured by deuterium incorporation (DI) and mass isotopomer distribution analysis (MIDA), cholesterol fractional and absolute synthetic rates were measured simultaneously by both techniques under identical physiological conditions. Twelve subjects (22 to 39 years of age) underwent a dual stable isotope protocol, involving oral deuterium oxide admi...

Tamoxifen is widely used in breast cancer therapy and in the treatment of all stages of breast cancer including chemoprevention in women at high risk of the disease. The most important aspect of tamoxifen therapy concerns its influence on bone tissue and lipid metabolism. The aim of the study was to evaluate the effect of tamoxifen on bone metabolism and blood cholesterol levels in ovariectomiz...

Plasma membrane sphingomyelin (SM) is known to affect the cellular distribution of cholesterol. The aim of this work was to examine how SM homoeostasis in human skin fibroblasts is affected by alterations in the level of cholesterol in the cell. The cellular cholesterol level was decreased by exposing cells to 2-hydroxypropyl-beta-cyclodextrin, and increased by exposing cells to cholesterol-met...

conclusions synbiotic supplementation may improve lipid profile and body composition in patients with nafld and might be useful in prevention of the disease progression. methods eighty patients with nafld participated in this randomized, double-blind, placebo-controlled clinical trial (from march to july 2014) in iran. based on ast and alt as main variables of the study, 34 patients were requir...

background: beta-thalassemia is considered to be the most frequent hereditary blood disorder worldwide. lipid abnormalities have been detected in different types of beta-thalassemia . the aim of this study is to assess the lipid profiles in beta-thalassemia major (btm) and beta-thalassemia intermedia (bti) patients in southern iran. methods: the study group consisted of 55 btm patients and 50 b...

Background: Cirrhosis is a common hepatological disorder seen in clinical practice. Liver plays an essential role in lipid metabolism, several stages of lipid synthesis and transportation. It is reasonable to expect an abnormal lipid profile in those with severe liver dysfunction Aim: To assess the lipid profile abnormalities in patients with cirrhosis of liver correlate with the severity of ci...

Human interferon-alpha was associated in different ways with positively (stearylamine) and negatively (phosphatidylserine) charged phosphatidylcholine multilamellar vesicles, depending on the presence or absence of a cholesterol component. Inclusion of cholesterol resulted in interferon that was significantly (P = 0.0001) more deeply internalized within the liposomes, such that detergent disrup...

Measurement of mevalonic acid (MVA) concentrations in plasma or 24-h urine samples is shown to be useful in studies of the regulation of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase and cholesterol synthesis. Plasma MVA concentrations, measured either at 7-9 a.m. after an overnight fast, or throughout the 24-h cycle, were compared with cholesterol synthesis rates that were measured...
