Quality of pork depends on genotype, rearing and pre- and post-slaughter conditions. However, no information is available on rearing system changes and oleic acid supplementation on carcass characteristics and fatty acid (FA) profile of pork from the Alentejano (AL) pig, an obese breed. This study evaluates the effects of feeding low (LO) or high oleic acid diets (HO) to AL pigs reared in indiv...

It is widely accepted that menopause leads to changes in hormonal status, metabolism and lipid profile. The aim of this study was to analyze the influence of menopause on the concentrations of lipids, lipoproteins and, the influence of estradiol, progesterone, FSH, LH on lipid profile in menopausal women as well. The menopausal women had higher but non-significant (p>0,05) concentrations of tot...

BACKGROUND Adiponectin, a circulating adipocyte-derived protein, has insulin-sensitizing, anti-inflammatory, antiatherogenic, and cardiomyocyte-protective properties in animal models. However, the systemic effects of adiponectin in humans are unknown. Our aims were to define the metabolic profile associated with higher blood adiponectin concentration and investigate whether variation in adipone...

The aim of this review is to place a historical perspective on linking dyslipidaemia with atherosclerosis and emphasises previous knowledge about the impact on the lipoprotein profile and health in persons with mild dyslipidaemia and in those with defined genetic disorders. CVD is becoming the leading cause of death and disability in developed and developing countries and is strongly related to...

PURPOSE To examine the deposition of tear phospholipids and cholesterol onto worn contact lenses and the effect of lens material and lens care solution. METHODS Lipids were extracted from tears and worn contact lenses using 2:1 chloroform:methanol and the extract washed with aqueous ammonium acetate, before analysis by electrospray ionization tandem mass spectrometry (ESI-MS/MS). RESULTS Tw...

BACKGROUND Diabetic patients with concomitant dyslipidemia are often soft targets for cardiovascular disease and deaths. An early intervention to normalize circulating lipids has been shown to reduce cardiovascular morbidity and mortality. Glycosylated hemoglobin (HbA1c) is routinely used as a marker to indicate long-term glycemic control. AIM Our aim was to test whether HbA1c can serve as a ...

Five different species of Crotalaria were analysed for their proximate and mineral composition, protein fractions, amino acid profile of total seed proteins, fatty acid profile of seed lipids, in vitro protein digestibility vitamins (niacin and ascorbic acid) and certain anti-nutritional factors. The major findings of the study were as follows: crude protein content ranged from 12.50 27.12%, cr...

The function of membrane proteins often depends on the proteins' interaction with their lipid environment, spectacularly so in the case of mechanosensitive channels, which are gated through tension mediated by the surrounding lipids. Lipid bilayer tension is distributed quite inhomogeneously, but neither the scale at which relevant variation takes place nor the effect of varying lipid compositi...

RESEARCHDESIGNANDMETHODSdA total of 844 subjects (44%men; age 49.56 11 years; BMI 296 5 kg/m) participated in this study. Parameters ofb-cell functionwere derived from deconvolution of the plasma C-peptide concentration after a 75-g OGTT and insulin sensitivity assessed by homeostasis model assessment of insulin resistance (IR). Cardiovascular risk profile was based on determination of plasma l...

Research into the cell biology of intracellular pathogens has provided information on host-pathogen interactions and on the importance of lipids at various stages in the interactions. Lipids are “gatekeepers” in important chemical reactions involving cell signaling during pathogen docking, invasion and traffic in and out of cells. Working with the Novartis Institute for Tropical Diseases, our t...
