The metabolic syndrome mostly represented by obesity and hyperinsulinaemia connected with insulin resistance, presents the main mechanism in the pathogenesis of cardiovascular disease. The aim of this study was to analyze the interrelations between several metabolic variables (including leptin) and factors related to insulin resistance in groups of both normal and non-diabetic hyperlipemic post...

The utilization of muscle triacylglycerols was studied during and after prolonged bicycle ergometer exercise to exhaustion in eight healthy young men. Two days before exercise and in the postexercise recovery period, subjects were fed a carbohydrate-rich diet (65-70% of energy from carbohydrates). Exercise decreased muscle glycogen concentrations from 533 ± 18 to 108 ± 10 mmol/kg dry wt, wherea...

BACKGROUND The effect of weight loss on different plasma lipid subclasses at the molecular level is unknown. The aim of this study was to examine whether a diet-induced weight reduction result in changes in the extended plasma lipid profiles (lipidome) in subjects with features of metabolic syndrome in a 33-week intervention. METHODOLOGY/PRINCIPAL FINDINGS Plasma samples of 9 subjects in the ...

UNLABELLED The purpose of this study was to establish blood glucose and lipid profile of Makerere University undergraduate students. STUDY DESIGN This was a cross-sectional study. MATERIALS AND METHODS A total of 183 students participated in the study. Capillary blood glucose was read instantly on a finger prick sample off Sensorex glucose analyzer. Venous blood from the antecubital vein wa...

In our study, 213 healthy Czech women aged 20 to 65 years were examined and divided into fully reproductive, premenopausal, menopausal and postmenopausal groups. In all subjects body composition was determined by classical anthropometry and metabolic profile was assessed. A total of 146 subjects completed 3-year longitudinal study. Total and LDL cholesterol increased and ratio HDL/total cholest...

Unlike other vertebrates, liver is the main site of lipid biosynthesis and is particularly very active in egg laying adult females. Yolk lipids and proteins are secreted as lipoproteins under the influence of estrogen in the liver. When hepatic lipogenesis exceeds the capacity of fat transport as lipoproteins, triacylglycerols commence to accumulate in the liver, leading to fatty liver syndrome...

Eicosapentaenoic and docosahexaenoic acids were distributed mainly in the sn-1 and 3 positions of seal oil triacylglycerols and in the sn-2 position of fish oil triacylglycerols. Seal oil-rich or fish oil-rich fats having constant polyunsaturated (PUFAs)/monounsaturated/saturated fatty acids and n-6/n-3 PUFAs ratios were fed to hamsters for 3 weeks. The control fat contained linoleic acid as th...

Adipose tissue is considered as the body's largest storage organ for energy in the form of triacylglycerols, which are mobilized through lipolysis process, to provide fuel to other organs and to deliver substrates to liver for gluconeogenesis (glycerol) and lipoprotein synthesis (free fatty acids). The release of glycerol and free fatty acids from human adipose tissue is mainly dependent on hor...

The lipid and fatty acids of the Pacific oyster, Crassostrea gigas, collected both in Japan and France, were analyzed. Triacylglycerols and sterols were the major classes in the neutral lipids of both populations of C. gigas between the two countries, and they had significant levels of phospholipids (phosphatidylethanolamine and phosphatidylcholine) with ceramideaminoethylphosphonate in their p...
