The oxidation processes of linoleic acid in the presence of ferulic acid, and 1-pentyl, 1-hexyl and 1-heptyl ferulates were observed at various temperatures and different molar ratios of each additive to linoleic acid. The processes were analyzed based on a kinetic equation of the autocatalytic type to evaluate the oxidative rate constant, k, and the kinetic parameter, Y(0), by which the initia...
Background: For understanding the roles of fatty acids on the induction of acrosome reaction which occurs under association of cholesterol efflux and PKA or PKC pathways in boar spermatozoa, metabolic fate of alone and combined radiolabeled 14C-oleic acid and 3H-linoleic acid incorporated in the sperm was compared, and behavior of cholesterol and effects of PKA and PKC inhibitors upon fatty aci...
Background: Feeding unsaturated fatty acids sources in dairy cows is considered as a strategy to improve animal health during postpartum period and milk fatty acid profile. OBJECTIVES: This study aimed to investigate the effects of conjugated linoleic acid supplement and combination of sesame meal and oil on performance and milk fatty acid composition of dairy cows during transition period. MET...
Maize shows wide differences in linoleic acid due both to total lipid content and to fatty acid profile. Therefore, diets containing the same high maize percentage (up to 55%) can differ in linoleic acid content and lead to subcutaneous fats of differing suitability for raw ham curing. Two trials were performed on heavy pigs; in the first, 60 pigs (body weight 48.7+/-5.1 kg) were fed three diet...
Effects of C18 Fatty Acids on Intracellular Ca2+ Mobilization and Histamine Release in RBL-2H3 Cells
To investigate the underlying mechanisms of C18 fatty acids (stearic acid, oleic acid, linoleic acid and α-linolenic acid) on mast cells, we measured the effect of C18 fatty acids on intracellular Ca(2+) mobilization and histamine release in RBL-2H3 mast cells. Stearic acid rapidly increased initial peak of intracellular Ca(2+) mobilization, whereas linoleic acid and α-linolenic acid gradually ...
Linoleic acid, with a DRI of 12-17g/d, is the most highly consumed polyunsaturated fatty acid in the Western diet and is found in virtually all commonly consumed foods. The concern with dietary linoleic acid, being the metabolic precursor of arachidonic acid, is its consumption may enrich tissues with arachidonic acid and contribute to chronic and overproduction of bioactive eicosanoids. Howeve...
larva. In both respects it resembles the effect of docosahexaenoic acid from cod-liver oil. 2. Ascorbic acid, in combination with the saponifiable fraction of wheat-germ oil, has a positive growth effect which is attributed to an antioxidant action. 3. The linoleic acid content of various insect oils has been estimated by testing their effect on the wings of Ephe8tia. Oils from Tenebrio and Eph...
the effect of kaolin on fruit and oil of olive cv. `zard’ was evaluated in a commercial orchard in fasacity, fars province. mature olive trees cv. `zard’ were sprayed with 0, 3 and 6% kaolin after 60 days, 60and 90 days and 60, 90, 120 days after full bloom. results showed that kaolin concentration and sprayingtime had not significant effects on physicochemical parameters but they had significa...
background: the aim of this study was to evaluate the effects of conjugated lino-leic acid (cla) on apoptosis of tachyzoites of t . gondii , rh strain (type i) and the cyst-forming tehran strain (type ii) in vitro. methods: toxoplasma strains were injected into the peritoneal cavity of balb/c mice. the tehran strain forms cysts in the brain of mice. bradyzoites within the cysts are reactivated ...
background: reactive oxygen species (ros) have important role in the etiology and pathogenesis of rheumatoid arthritis (ra). we investigated the effect of conjugated linoleic acids (clas) and vitamin e on lipid peroxidation. methods: in a randomized, double-blind placebo, controlled, clinical trial 87 patients with active ra were enrolled. they were divided into 4 groups, received one of the fo...
