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...

Two endemic Cirsium species, C. leucopsis DC. and C. sipyleum O. Schwarz, and C. eriophorum (L.) Scop. growing in Turkey were investigated to establish their secondary metabolites, fatty acid compositions, and antioxidant and anticholinesterase potentials. Spectroscopic methods were used to elucidate the structures of thirteen known compounds (p-hydroxy-benzoic acid, vanillic acid, cis-epoxycon...

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...

Objective: Menopause is the condition when regular menstrual periods cease and may be accompanied by psychological and physical symptoms. The purpose of current study was to determine Nigella sativa effects on reproductive system in experimental menopause animal models. Materials and Methods: A series of experiments wasconducted to investigate the effects of different dosages of N. sativa (firs...

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...

Cystic fibrosis (CF) patients display a fatty acid imbalance characterized by low linoleic acid levels and variable changes in arachidonic acid. This led to the recommendation that CF patients consume a high-fat diet containing >6% linoleic acid. We hypothesized that increased conversion of linoleic acid to arachidonic acid in CF leads to increased levels of arachidonate-derived proinflammatory...

Oleic acid, a monounsaturated, omega-9 fatty acid found in peanut (Arachis hypogaea L.) oil is an important seed quality trait because it provides increased shelf life, improved flavor, enhanced fatty acid composition, and has a beneficial effect on human health. Hence, a concentrated effort has been put forth on developing peanut cultivars that have high oleic acid ( [74%) and a low amount (\ ...
