The formation of hydroxystearic acid (HSA) and ketostearic acid (KSA) from oleic acid transformation has been documented in a variety of microbial species, including several isolated from the rumen of domesticated ruminant species. However, their ruminal production rates have not been established as influenced by fatty acid source. Dosing continuous cultures of mixed ruminal microorganisms with...

Islet adaptation to pregnancy is largely influenced by prolactin and placental lactogens. In addition serum lipids are significantly increased. Here, we report the novel observation that prolactin and oleic acid synergistically stimulate islet cell proliferation and islet growth. In neonatal rat islets, prolactin increased proliferation 6-fold, oleic acid 3.5-fold, and their combination 15-fold...

3-trifluoromethylphenyldiazirine based oleic acids derivatives are synthesized to elucidate the functions of specific activation of protein kinase C (PKC) with oleic acid. The synthetic route is based on the alkylation of phenolic derivative with oleic acid equivalent and the post-functionalization of the compound to achieve radiolabeling. Several compounds have biological activity for PKC with...

The effects of eicosapentaenoic acid and oleic acid on lipid synthesis and secretion by HepG2 cells were examined to identify fatty acid specific changes in lipid metabolism that might indicate a basis for the hypolipidemic effect attributed to eicosapentaenoic acid and related n-3 fatty acids. Cellular glycerolipid synthesis, as determined by [3H]glycerol incorporation, increased in a concentr...

In this study we investigated the effects on lipoproteins of medium chain fatty acids (MCFA) and myristic acid relative to those of oleic acid. Thirty-seven women and 23 men consumed a 3-wk run-in diet enriched in oleic acid followed by a 6-wk test diet rich in MCFA (n = 21), myristic (n = 20), or oleic acid (n = 19). Experimental fats were incorporated into solid foods. Total fat intake was 40...

Under appropriate conditions, oleic acid replaces biotin for several lactic acid bacteria.‘, z This growth-promoting action of oleic acid is not nullified by excess avidin for Streptococcus jaecalis R2 or for several other organisms (Table I). Egg white did, however, block utilization of oleic acid by Lactobacillus arabinosus (Table I). This result is obtained whether oleic acid is added alone,...

zinc oxide nano-particles with the average diameter of about 25 nm were modified with different mole ratios of trimetoxyvinyl silane (tmvs) and oleic acid, as coupling agents, in order to modify their surface properties and render them more hydrophobic. then, dispersibility of the surface modified nano-particles was examined in some monomers with different levels of hydrophobicity, including me...

A mixture of eight fatty acids (linoleic, oleic, palmitic, stearic, myristic, elaidic, lauric, and palmitoleic acids) at similar concentrations that have been identified in human amniotic fluid exerts anxiolytic-like effects similar to diazepam in adult Wistar rats through actions at γ-aminobutyric acid-A (GABAA) receptors, but unknown is whether any of these fatty acids exerts a predominant ac...

introduction: nonalcoholic fatty liver disease (nafld) is a global disease which its prevalence is about 10-35%. several factors are involved in the pathogenesis of the disease. the present study was conducted to evaluate the effect of fasting during ramadan on plasma free fatty acids in patients with nafld.methods: this cross-sectional study was performed during the month of ramadan in june-ju...

safflower (carthamus tinctorius l.) is one of the oilseed plants that can influence strongly on oilseed security because it is extremely compatible with environmental conditions. safflower is cultivated as second cultivation after combining cereals in isfahan. nowadays many attempts are performed to improve safflower oil quality to use in edible oil industry. in this study, quantity and quality...
