BACKGROUND Chronic exposure to the glucocorticoid hormone corticosterone exerts cellular stress-induced toxic effects that have been associated with neurodegenerative and psychiatric disorders. Docosahexaenoic acid is a polyunsaturated fatty acid that has been shown to be of benefit in stress-related disorders, putatively through protective action in neurons. METHODS We investigated the prote...

Sleep problems in children are associated with poor health, behavioural and cognitive problems, as are deficiencies of long-chain omega-3 fatty acids such as docosahexaenoic acid. Theory and some evidence support a role for these fatty acids in sleep regulation, but this issue has received little formal investigation. We examined associations between blood fatty acid concentrations (from finger...

Female Wistar rats, 100 weeks old, were divided into four groups: one group was fed a high-cholesterol diet, one received a non-cholesterol diet, and the others were fed either a non- or a high-cholesterol diet plus docosahexaenoic acid. The level of lipid peroxide (LPO) in brain tissue was measured with a LPO assay kit. Fatty acid concentrations were analyzed by gas chromatography. Brain LPO i...

A Brownian dynamics (BD) simulation of two unsaturated molecules, oleic and docosahexaenoic acid, in an environment that reproduces a cellular membrane, is presented. The results of the simulations, performed using mean-field potentials, were calibrated with experimental results obtained for oleic acid in a cellular membrane. The agreement between simulation and experimental results is excellen...

Handling & Preparation Instructions This purified fatty acid is liquid at room temperature (oil) and not soluble in water. The product is supplied sterile. It can be solubilized in undiluted serum, ethanol or DMSO. The solubility of Docosahexaenoic acid in ethanol is at least 100 mg/ml. Docosahexaenoic acid has a solubility of 1 mg/ml in a solution of 0.15 M Tris-HCL (pH 8.5). We strongly recom...

The metabolism of the linolenic acid family (n-3) of fatty acids, e.g., linolenic, eicosapentaenoic, and docosahexaenoic acids, in cultured smooth muscle cells from rabbit aorta was compared to the metabolism of linoleic and arachidonic acids. There was a time-dependent uptake of these fatty acids into cells for 16 hr (arachidonic greater than docosahexaenoic, linoleic, eicosapentaenoic greater...

Introduction Docosahexaenoic acid (DHA) is an omega-3 fatty acid that falls into the larger category of polyunsaturated fatty acids (PUFAs). Although many chronic conditions are associated with excessive intake of dietary saturated and trans fatty acids (including obesity, insulin resistance, coronary heart disease, and some forms of cancer), research shows omega-3 fatty acids, including DHA, a...

Helicobacter pylori infection, the most common chronic bacterial infection in the world, and an important cause of gastrointestinal disorders, may be involved in the pathogenesis of some extra-gastrointestinal disturbances, as well as an increase in blood levels of certain inflammatory markers. Anti-bacterial activity against Helicobacter pylori and anti-inflammatory properties of omega-3 fatty...

Dietary triglycerides containing predominantly poly-unsaturated fatty acids (PUFAs) are known to reduce plasma total and low density lipoprotein (LDL) cholesterol concentrations relative to triglycerides containing predominantly saturated fatty acids. However, there is little information regarding the independent effects of individual n-6 and n-3 PUFAs on LDL metabolism. The present studies wer...

OBJECTIVE We investigated the effect of docosahexaenoic acid (DHA) on the invasion and metastasis of ovarian cancer cells (A2780, HO8910, and SKOV-3). METHODS Cytotoxicity assay was performed to determine the optimal doses of DHA in this experiment. The effects of DHA on invasion ability were assessed by invasion assay. The expressions of messenger RNA and/or proteins associated with invasion...
