Polyunsaturated fatty acids (PUFAs), especially n-3 polyunsaturated fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are known to protect against inflammation-induced bone loss in chronic inflammatory diseases, such as rheumatoid arthritis, periodontitis and osteoporosis. We previously reported that DHA, not EPA, inhibited osteoclastogenesis induced by the receptor activ...

In this placebo controlled, randomised, double blind trial, pregnant women received from the 20th week of gestation onwards either 500 mg docosahexaenoic acid (DHA), 400 mg 5-methyl-tetra-hydro-folate (5-MTHF), or placebo, or a combination of 500 mg DHA and 400 mg 5-MTHF. The dietary supplements were well tolerated; the dropout rates did not differ significantly in the active arms of the study ...

Mitsohiro Yokohama and colleagues 1 noted that non-fatal coronary events, but not cardiac deaths, were lower in hypercholesterolaemic Japanese patients who were given 1800 mg per day of the omega 3 fatty acid eicosapentaenoic acid (EPA) than in controls. At first, these results seem to contrast with other published data which indicate that omega 3 fatty acid preparations, including the end prod...

We have isolated the fatty acid biosynthetic (fab) gene cluster taking part in the synthesis of middle-chain fatty acids and a genomic segment which was homologous with the eicosapentaenoic acid-biosynthetic gene cluster from the docosahexaenoic acid (DHA)-producing bacterium Moritella marina strain MP-1. This segment was presumed to include the DHA-biosynthetic gene cluster of M. marina strain...

BACKGROUND The visual and mental development of preterm infants improved after feeding them milk enriched with docosahexaenoic acid (DHA) in amounts matching the fetal accretion rate. OBJECTIVE The objective was to evaluate whether feeding preterm infants milk with a higher DHA content than that used in current practice influences language or behavior in early childhood. DESIGN This was a f...

Integrity of retinal pigment epithelial cells is necessary for photoreceptor survival and vision. The essential omega-3 fatty acid, docosahexaenoic acid, attains its highest concentration in the human body in photoreceptors and is assumed to be a target for lipid peroxidation during cell damage. We have previously shown, in contrast, that docosahexaenoic acid is also the precursor of neuroprote...

Fungal cultures were isolated from soil samples collected from the Western Ghats regions of Kerala. Primary screening of isolated strains were done by Sudan black staining method and 15 lipid producing cultures were isolated. The fatty acid profiling of the positive strains were analyzed for docosahexaenoic acid (DHA) production. Selected oleaginous cultures were grown in submerged culture cond...

Docosahexaenoic acid (DHA), a long-chain omega-3 polyunsaturated fatty acid, has been used to treat a range of different conditions, including periodontal disease (PD) and inflammatory bowel disease (IBD). That DHA helps with these oral and gastrointestinal diseases in which inflammation and bacterial dysbiosis play key roles, raises the question of whether DHA may assist in the prevention or t...

The effects of carbon sources, seawater concentration and seawater component in a culture medium were investigated to optimize culture conditions for growth by a marine thraustochytrid Aurantiochytrium limacinum strain mh0186. Strain mh0186 could utilize D-glucose, D-fructose and D-mannose as carbon sources. Seawater concentrations between 12.5 - 200% were required for good growth, and a single...

A phosphopantetheinyl transferase (PPTase) gene (pfaE), cloned from the docosahexaenoic acid (DHA)-producing bacterium Moritella marina strain MP-1, has an open reading frame of 861 bp encoding a 287-amino acid protein. When the pfaE gene was expressed with pfaA-D, which are four out of five essential genes for biosynthesis of eicosapentaenoic acid (EPA) derived from Shewanella pneumatophori SC...
