Purified prostaglandin endoperoxides (PGG2 and PGH2) and hydroperoxides (15-OOH-PGE2) as well as fatty acid hydroperoxides (12-OOH-20:4, 15-00H-20:4, and 13-OOH-18:2) were examined as effectors of soluble splenic cell guanylate cyclase activity. The procedures described (in the miniprint supplement) for the preparation, purification, and characterization of these components circumvented the use...

Isoelectric solubilization /precipitation (ISP) process was used to isolate protein from muscles of Prussian carp, Carassius gibelio (Bloch, 1782). Fish protein and lipid were recovered from whole gutted Prussian carp using acidic and basic isoelectric solubilization/precipitation followed by assaying amino acid and fatty acid profile. Essential amino acids content in acidic and basic pH treatm...

cardiovascular disease (cvd) is the leading cause of death and disability in developed countries. atherosclerosis is the major cause of cvd, accounting for about half of the attributed deaths. cholesterol homeostasis is one of the most important factors in atherosclerosis. atp-binding cassette transporters cholesterol. omega (ω) 3 fatty acids are important ligands for regulation of abc transpor...

Agaricus bisporus and Agaricus bitorquis are among most favorite mushrooms of the world. Mineral contents, proximate composition and fatty acid profile of these mushrooms were determined for evaluation of their dietary value. Na, K and Li contents were high, while Cr, Cu, Pb, Co, Zn, Mn and Ni concentrations were low in both Agaricus bisporus and Agaricus bitorquis. Proximate analysis showe...

abstract introduction: omega 3 fatty acid especially in the form of fish oil, has structural and biological role in the body's various systems especially nervous system. numerous studies have tried to research about it. auditory is one of the affected systems. omega 3 deficiency can have devastating effects on the nervous system and auditory. this study aimed to evaluate neural conduction ...

background: the production of waste pollutants has become a major problem for many food and oil industries. however, oil wastes can provide alternative substrates for industry, which could help to solve environmental pollution problems. furthermore, oil wastes can be used as substrates to produce unsaturated fatty acids, which are important for health.objectives: the production of fatty acids i...

background: the lipids of the spermatozoa membrane are important for the fluidity and flexibility of spermatozoa. however, spermatozoa’s lipids are the main substrates for peroxidation, which may provoke severe functional disorder of sperm. objective: the aim of this study was to investigate the fatty acids composition of spermatozoa in men with asthenozoospermia, asthenoteratozoospermia and ol...

Dipeptides absorbed by the intestinal epithelium are delivered to circulation, but their metabolic roles are not yet clearly understood. We investigated the biological activities of a dietary dipeptide, H-Trp-Arg-OH (WR), on the regulation of peroxisome proliferator-activated receptor (PPAR) α activity. Reporter gene assays revealed that WR dose-dependently induced PPARα transactivation. Surfac...

The NADPH-dependent enoyl coenzyme A reductase activity of bovine mammary fatty acid synthetase has been characterized with regard to substrate specificity and the product formed. A relatively high specificity for an unsubstituted, four-carbon, 2,3-enoyl chain in trans configuration is obtained. Reduction of trans-crotonyl-CoA results in butyrate, 50% of which is coenzyme A-bound. The reaction ...

introduction: frying is one of the most popular cooking methods. however, harmful substances are created during the frying process, with the stability of oil negatively affected. this study evaluates the stability of fatty acid content of several cooking and frying oils available on the iranian market during the process of frying. materials and methods: samples from 5 different frying oils and ...
