Among various organs, in the brain, the fatty acids most extensively studied are omega-3 fatty acids. Alpha-linolenic acid (18:3omega3) deficiency alters the structure and function of membranes and induces minor cerebral dysfunctions, as demonstrated in animal models and subsequently in human infants. Even though the brain is materially an organ like any other, that is to say elaborated from su...

Mice were fed a diet deficient in alpha-linolenic acid [18:3 (n-3)] or a control diet and the effect of this deficiency was assessed by behavioral and pharmacological measurements. Three weeks before mating female mice were fed a diet containing either peanut oil poor in alpha-linolenic acid (n-3)- or peanut+rapeseed oil rich in alpha-linolenic acid (n-3)+ = controls. Pups, aged 47 to 61 days, ...

Epidemiological studies have suggested inconsistent associations between omega-3 polyunsaturated fatty acids (n-3 PUFAs) and prostate cancer (PCa) risk. We performed a dose-response meta-analysis of prospective observational studies investigating both dietary intake and circulating n-3 PUFAs and PCa risk. PubMed and EMBASE prior to February 2014 were searched, and 16 publications were eligible....

We studied the effects of five high-fat semi-purified diets varying at a 4% (w/w) level in either stearic, oleic, linoleic, alpha-linolenic, or gamma-linolenic acid on body fat and energy metabolism in BALB/c mice. A diet containing caprylic, capric, lauric, and myristic acid was used as a reference diet and a diet with 4% conjugated linoleic acid (CLA) was used as a positive control as it is k...

Wild berry varieties are widely distributed in Canada and mainly used by the indigenous population as food. Gooseberries blackcurrant two tart berries with strong taste that to make preserves such jams, jellies, wine. Phenolic compounds fatty acids predominant bioactive metabolites present these berries. Recently, researchers more interested exploring fruits for functional properties benefit hu...

Sesamin is known as a specific inhibitor of delta 5-desaturation, the conversion from dihomo-gamma-linolenic acid (20:3(n=6)) to arachidonic acid (20:4(n-6)). In the previous paper, we reported that sesamin inhibited delta 5-desaturation of n-6 fatty acids in rat hepatocytes but not that of n-3 fatty acids, from 20:4(n-3) to 20:5(n-3). Then, we studied the effects of sesamin on delta 5-desatura...

Reactive oxygen species (ROS) are elevated by metabolic changes in diabetes, including autoxidation and increased advanced glycation. Endogenous protection by the glutathione redox cycle is also compromised by the competing NADPH requirement of elevated polyol pathway flux. Antioxidant treatment strategies prevent or reverse nerve conduction velocity (NCV) deficits in diabetic rats. These inclu...

background and objectives:wild sage(salvia macrosiphon boiss.) known as “marvak” in persian is one of the polymorphic and abundant plants of lamiaceae. the plants whole seeds usually soaked or boiled in hot water are widely used for inflammatory ailments in folk medicine. documents have shown that there is scant information on the chemical constituents of this plant seeds. the current study was...

Dietary intake of the n-6 fatty acid (FA) linoleic acid (LA) has a strong growth-promoting effect on many rodent tumors and human tumor xenografts grown in immunodeficient rodents. n-3 FAs such as alpha-linolenic and eicosapentaenoic acids (EPAs), which differ from LA and arachidonic acid, respectively, by only a single double bond in the n-3 position, are recognized cancer chemopreventive and ...
