Background: The dried fruits of Silybum marianum (L.) Gaertn (Compositae) contain silymarin, an isomeric mixture of flavonolignans. Silymarin acts as a strong anti -hepatotoxic. This fruits contains a high amount of oil .  Objective: The objective of this study was to determine total lipid content, fatty acid composition and content of different kind of tocopherols in seed oils of S. marianum...

The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...

Oleic acid and angiotensin II (Ang II) are elevated and may interact to accelerate vascular disease in obese hypertensive patients. We studied the effects of oleic acid and Ang II on growth responses of rat aortic smooth muscle cells (VSMCs). Oleic acid (50 mmol/L) raised thymidine incorporation by 50% at 24 hours and cell number by 55% at 6 days (P,.05). Ang II (10 to 10 mol/L) did not signifi...

A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...

The effects of eicosapentaenoic acid on synthesis and secretion of cholesterol and cholesterol ester by cultured rat hepatocytes were studied. In the presence of eicosapentaenoic acid cellular cholesterol esterification was decreased by 50-75% compared to oleic acid as measured by radioactive precursors and mass. Secretion of cholesterol ester was reduced by 50-60% in the presence of eicosapent...

OBJECTIVE Pulmonary surfactant-associated protein B (SP-B), which is synthesized and secreted by alveolar epithelial type II cells, is crucial for normal functioning of pulmonary surfactant. Degeneration of pulmonary surfactant is the essential cause of acute lung injury (ALI). ALI is often studied in animal models using oleic acid, and the effects of oleic acid on pulmonary surfactant and SP-B...

For determining the fatty acid characteristics and biodiesel quality of Ethiopian Jatropha provenances, the study was conducted in five regions namely Southern Nation Nationalities Peoples Regional State (SNNPRS), Amhara region, Tigria region, Oromia region and Benishangul Gumuz Regions, where physic nut is found abundantly. For each region, representative sampling sites were selected following...

The esterification of free fatty acids (FFA) with methanol is studied using Sulfonated Porous Carbon (SPC) as catalyst. In compare to the amorphous sugar catalyst and protonated Nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. The highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol H+ and mole ra...

Ruminant products are significant sources of dietary trans fatty acids. Trans fatty acids, including various conjugated linoleic acid isomers, have been shown to act as metabolic modifiers of lipid metabolism. Trans fatty acids originate from biohydrogenation of dietary unsaturated fatty acids by gut microbes; however, the exact synthetic pathways are unclear. It was our goal to examine the bio...
