BACKGROUND
Evidence from in vitro and animal studies indicates that conjugated linoleic acid (CLA) possesses anti-diabetic properties, which appear to be attributed to cis-9, trans-11 CLA, the major CLA isomer in ruminant fat. However, there is a shortage of studies addressing CLA from natural
The JCR:LA-cp rat is obese, insulin resistant, and hyperlipidemic, and the males develop atherosclerosis and ischemic myocardial disease. Benfluorex at 35-40 mg.kg-1 body weight was administered in the food from 10 to 14 weeks of age and resulted in an initial 50% decrease in food consumption. Body
This study evaluated the ability of alpha1-adrenergic blockade to interfere with the development of diet-induced hyperlipidemia and deterioration of insulin action. Diets having extremely divergent effects on glucose and lipid metabolism were contrasted. Rats were fed for 4 weeks either a
BACKGROUND
The influence of hyperinsulinemia on concentrations of lipoprotein subfractions in obese, nondiabetic persons has not been clarified.
OBJECTIVE
We analyzed VLDL and LDL subfractions before and after a euglycemic, hyperinsulinemic clamp.
METHODS
Lipoprotein subfractions were isolated from
Recent studies have suggested that cholesteryl ester synthesis plays a critical role in the assembly of VLDL apo B and triacylglycerol in the liver. Chronic hyperinsulinemia is associated with increased TG production and since cholesteryl ester synthesis depends on acyl CoA:cholesterol
Hyperuricaemia is one of the components of metabolic syndrome. Both oxidative stress and hyperinsulinism are important variables in the genesis of this syndrome and have a close association with uric acid (UA). We evaluated the effect of an oral glucose challenge on UA concentrations. The study
California mice (Peromyscus californicus) develop type II diabetes mellitus when fed a high-fat diet. We undertook the current studies to determine whether hyperlipidemia precedes the development of insulin resistance and to establish breeding colonies of hyperlipidemic and normolipidemic mice. For
The aim of the present study was to evaluate the effect of exercise training on glucose tolerance and glycogen and triacylglycerol (TG) content in different types of skeletal muscles and in the liver of rats fed with a high-fat diet. From 8 to 11 weeks of age male Wistar rats were fed with
BACKGROUND
Angiopoietin-like protein 4 (ANGPTL4) is an extracellular inhibitor of lipoprotein lipase (LPL) activity. No studies have been done in pregnancy in which hypertriglyceridemia and tissue-specific changes in LPL activity are present.
OBJECTIVE
The objective of the study was to determine the
BACKGROUND
Plasma follistatin is elevated in patients with low-grade inflammation and insulin resistance as observed with polycystic ovary syndrome. In the present study, we evaluated plasma follistatin in patients with type 2 diabetes characterised by low-grade inflammation and assessed the acute
Although exercise is effective in improving obesity and hyperinsulinemia, the exact influence of exercise on the capillary density of skeletal muscles remains unknown. The aim of this study was to investigate the effects of low-intensity exercise training on metabolism in obesity with
The JCR:LA-cp rat develops an extreme obese/insulin-resistant syndrome such that by 12 weeks of age, there is no longer any insulin-mediated glucose turnover. At 4 weeks of age, obese and lean rats have essentially identical basal and insulin-mediated glucose uptake in skeletal muscle. By 8 weeks of
BACKGROUND
Abdominal fat and circulating triacylglycerols increase with age, which indicates lipid overaccumulation. Enlarged waist (EW) with elevated triacylglycerols (ET) could identify adults at metabolic risk.
OBJECTIVE
Using thresholds for EW and ET observed among the youngest adults, we
This review has considered a number of observations obtained from studies of insulin in perfused liver, hepatocytes, transformed liver cells and in vivo and each of the experimental systems offers advantages. The evaluation of insulin effects on component lipid synthesis suggests that overall, lipid
The effects of feeding saturated and eucaloric unsaturated fat-rich diets on lipemia and insulinemia in female Brown Norway rats have been compared. The relative hyperlipemia in the unsaturated fat group at 8 a.m. has declined at 10 a.m., whereas the saturated fat group at 8 a.m. gives lower values
