Oxidants released from inflammatory cells contribute to the pathogenesis of acute inflammatory edema in many models. Chemically produced oxidants can reversibly alter the barrier properties of cultured endothelial and epithelial monolayers. This report examines the effects of nonlytic doses of H2O2 on endothelial cell lipids. H2O2 oxidized omega-6 fatty acids in the endothelial cells and initia...

Since the small intestine contributes significantly to serum cholesterol and very low density lipoprotein levels, acute regulation of lipid synthesis was investigated in isolated rat intestinal cells incubated in Krebs-Ringer bicarbonate buffer with 5 mM glucose and [14c]acetate or 3H2O. Incorporation of [14c]acetate into cellular lipids was 6- to 8-fold greater in crypt than in villus cells. I...

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 f...

this study was conducted to determine the concentrations of metals (zn, cu, pb, cd and hg) in two commercial fish species of the persian gulf (coast of bushehr province in iran), as well as in the sea waters. the concentrations of metals were determined by using differential pulse anodic stripping voltammetry (dpasv). two selected species were narrow-barred spanish mackerel and tiger tooth croa...

The anecdote "we are what we eat" in line with the doctrine of Hypocrates in 400 BC “Let food be thy medicine and medicine thy food” are vividly portray the importance of daily regimen in human health and body well-functioning. There is a growing body of evidence that suggests the relative intake of specific nutrients can have a profound effect on physiology of individuals...

CITREM is an emulsifier used in the food industry and contains citric acid esters of mono- and diglycerides (GCFE). It is generally recognized as safe but no publication on its digestibility under gastrointestinal conditions and impact on fat digestion was available. It was shown here that fatty acids are released from CITREM by gastric lipase, pancreatic lipase, pancreatic-lipase-related prote...

Background & Aim: Ocimum basilicum L. is belong to the Lamiaceae family which is cultivated as a culinary, industrial and medicinal plants in some countries from thousands years ago. The seed of this plant is rich in poly un-saturated fatty acids (PUFA) and produced a large amount of mucilage. Experimental: The oil of seed was extracted separately and converted to fatty acids...

A procedure, appropriate to use in the routine laboratory, is described for thin-layer chromatographic separation of serum lipids on silica gel, followed by molybdate coloring and densitometry. Cholesteryl aniline is used as the internal standard. The procedure is recommended as a screening procedure for presenting graphically the lipid distribution in the serum. Fractions separated and values ...
