Elevated concentrations of serum non-esterified fatty acids (NEFA), associated with maternal disorders such as obesity and type II diabetes, alter the ovarian follicular micro-environment and have been associated with subfertility arising from reduced oocyte developmental competence. We have asked whether elevated NEFA concentrations during oocyte maturation affect the development and physiolog...

Circulating NEFAs (non-esterified fatty acids) from adipose tissue lipolysis lead to endothelial dysfunction and insulin resistance in patients with the metabolic syndrome or Type 2 diabetes mellitus. The aim of the present study was to test the hypothesis that DHP (dihydropyridine) CCBs (calcium channel blockers) prevent NEFA-induced endothelial and haemorheological dysfunction independently o...

The fatty acid composition of liver mitochondrial phospholipids from rats rendered deficient in essential unsaturated fatty acids has been determined, and compared with that of rats fed a diet containing corn oil. In addition to marked reductions in the amounts of linoleic and arachidonic acids esterified a t the &position of ethanolamine-, inositol-, and choline glycerophosphatides, the defici...

Mycobacterium bovis BCG produces a variety of methyl-branched fatty acids. They include C28 to C32 mycocerosic acids esterified to phthiocerol and phenolphthiocerol and the shorter (C22 to C26) mycocerosic acids esterified to phthiocerol. A mycocerosic acid synthase gene-disrupted mutant was still able to produce the shorter mycocerosic acids. The enzyme short chain mycocerosic acid synthase (S...

G protein-coupled receptor 40 (GPR40), a receptor for diverse non-esterified fatty acids, is expressed predominantly in the wide variety of neurons of the central nervous system and β-cells in the pancreatic islets. Since deorphanization of GPR40 in 2003, the past decade has seen major advances in our understanding of its role in the insulin secretion. However, there is still a great deal to be...

BACKGROUND Liver steatosis was caused by lipid accumulation in the liver. Alisma orientale (AO) is recognized as a promising candidate with therapeutic efficacy for the treatment of nonalcoholic fatty liver disease (NAFLD). HepG2 hepatocyte cell line is commonly used for liver disease cell model. METHOD The HepG2 cells were cultured with the NEFAs mixture (oleic and palmitic acids, 2:1 ratio)...

Consumption by animals and humans of earthy materials such as clay is often related to gut pathologies. Our aim was to determine the impact of kaolinite ingestion on glucose and NEFA transport through the intestinal mucosa. The expression of hexose transporters (Na/glucose co-transporter 1 (SGLT1), GLUT2, GLUT5) and of proteins involved in NEFA absorption (fatty acid transporter/cluster of diff...

The regulation of the extramitochondrial fatty acid oxidation pathways located in the peroxisomes and the endoplasmic reticulum is not fully understood. Although both long-chain dicarboxylic fatty acids, which are poorly metabolized in hepatocytes, and non-beta-oxidizable fatty acid analogs induce peroxisomal beta-oxidation and liver fatty acid-binding protein (L-FABP) by a pretranslational mec...

Schaefer, Werner B. (National Jewish Hospital, Denver, Colo.), and C. Willard Lewis, Jr. Effect of oleic acid on growth and cell structure of mycobacteria. J. Bacteriol. 90:1438-1447. 1965.-The growth-stimulatory effect of fatty acids on Mycobacterium kansasii and other mycobacterial species is associated with transient changes in the morphology of the bacteria. One change observed is the appea...

Chylomicron triglyceride and lecithin obtained after feeding mixtures of three or four free fatty acids to rats were hydrolyzed using pancreatic lipase and phospholipase A respectively. The distribution of fatty acid mass and radioactivity in the substrate materials and in the cleavage products was determined by gas-liquid chromatography. The incorporation of exogenous (labeled) fatty acids int...
