The present authors investigated whether cystic fibrosis is linked to a defect in fatty acids and assessed the impact of the main patients' characteristics on the levels of several fatty acids, mostly during respiratory exacerbation and after antibiotic therapy. Fatty acid phospholipid and cholesteryl ester levels were measured in stable-state patients and controls. No differences were found co...

The immune system acts to protect the host against pathogenic invaders. However, components of the immune system can become dysregulated such that their activities are directed against host tissues, so causing damage. Lymphocytes are involved in both the beneficial and detrimental effects of the immune system. Both the level of fat and the types of fatty acid present in the diet can affect lymp...

High plasminogen activator inhibitor (PAI)-1 levels and poor dietary fat quality are potential risk factors for cardiovascular disease. The aim was to investigate the cross-sectional associations between PAI-1 activity and dietary nutrient intake, focusing on fat quality, in a population-based study of 871 men aged 70 years. The relationship between PAI-1 and the fatty acid composition in serum...

The enzymes that are involved in the elongation of fatty acids differ in terms of the substrates on which they act. To date, the enzymes specifically involved in the biosynthesis of polyunsaturated fatty acids have not yet been identified. In an attempt to identify a gene(s) encoding an enzyme(s) specific for the elongation of gamma-linolenic acid (GLA) (18:3n-6), a cDNA expression library was ...

background & aim: purslane (portulaca oleracea l.), belongs to the portulacaceace family, grows in many parts of iran. results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6.  portulaca oleracea is a widespread weed, being the eighth common plants of the world. the aim of current study was to compare the essential fatty acids com...

Many of the features of the premenstrual syndrome are similar to the effects produced by the injection of prolactin. Some women with the premenstrual syndrome have elevated prolactin levels, but in most the prolactin concentrations are normal. It is possible that women with the syndrome are abnormally sensitive to normal amounts of prolactin. There is evidence that prostaglandin E1, derived fro...
