PURPOSE: Essential fatty acids play a critical role in the growth and development of infants, but little is known about the fatty acid status of populations in low-income countries. The objective was to describe the fatty acid composition of red blood cells (RBC) in breastfeed Nepali infants and a subsample of their mothers and to identify the main sources of fatty acids in the mother's diet, as well as the fatty acid composition of breast milk. METHODS: RBC fatty acid composition was analyzed in a random sample of 303 infants and 72 mother, along with 68 breastmilk samples...

Lipids are important energy source and structural component for cellular membranes and tissues, involved in the osmoregulation and immune response, and are very important in the bioaccumulation of lipophilic chemicals too. Among lipids, fatty acids (FAs) give information on diet of organisms, since FA of consumer lipids can be related to those of diet; plants and animals vary in their FA signature because of differences in the synthesis of lipids. In this study, lipid content and FA composition in tissues of Antarctic organisms from the Ross Sea (Odontaster validus, Sterechinus neumayeri, Chionodraco hamatus, Trematomus bernacchii, Pygoscelis adèliae) were assessed...

INTRODUCTION: Long-chain (LC) omega-3 fatty acids (n-3 PUFAs) have beneficial effects on cardiovascular health and cognitive decline. Several studies have shown that the LC n-3 PUFA status in women in western countries is low. The aim of this study was to assess the LC n-3 PUFA status in middle-aged German women and to identify variables that might affect the status. MATERIAL AND METHODS: From the nationwide and cross-sectional German VitaMinFemin study, fatty acid levels in the erythrocyte membrane (% of total erythrocyte fatty acids) were ascertained for 446 women (40-60 years)...

Many bioactive components such as poly-unsaturated fatty acids (e.g. EPA and DHA), phospholipids and astaxanthin are known in Antarctic krill (Euphausia superba) oil. The krill DHA and EPA are generally considered to be similar to natural ones. However, two chemical compounds which were separated from Antarctic krill oil and identified as EPA and DHA by HRESIMS and NMR acted much more effective inhibitive activities on growth of several cell lines (U937, K562, SMMC-7721, PC-3, MDA-MB-231, HL60 and MCF-7) than those from sturgeon liver and commercial fish oil...

The pico-alga Ostreococcus tauri is a minimal photosynthetic eukaryote that has been implemented as model system. O. tauri is known to efficiently produce docosahexaenoic acid (DHA). We provide a comprehensive study of the glycerolipidome of O.tauri and validate this species as model for related picoeukaryotes. Ostreococcus lipids displayed unique features that combined traits from the green and the chromoalveolate lineages. The betaine-lipid diacylglyceryl-hydroxymethyl-trimethyl-β-alanine and phosphatidyldimethylpropanethiol, both hallmarks of chromalveolates, were identified as presumed extraplastidial lipids...

OVERVIEW: Whilst the majority of evidence supports the adjunctive use of eicosapentaenoic acid (EPA) in improving mood, to date no study exists using low-dose docosahexaenoic acid (DHA) alone as an adjunctive treatment in patients with mild to moderate major depressive disorder (MDD). METHODS: A naturalistic 8-week open-label pilot trial of low-dose DHA, (260 mg or 520 mg/day) in 28 patients with MDD who were non-responsive to medication or psychotherapy, with a Hamilton Depression Rating Scale (HAM-D) score of greater than 17, was conducted...

BACKGROUND: Improving motor unit recruitment and function is trainable and positively affects performance. Evidence suggests that supplementation of choline, uridine, and docosahexaenoic acid (DHA) may also enhance neuromuscular function. The purpose of this study was to assess the influence of acute ingestion of these supplements on anaerobic exercise performance and cognition. METHODS: Twenty college-aged trained males (21.2 ± 1.4 years, 181.2 ± 6.1 cm, 94.4 ± 20...

Omega-3 long chain polyunsaturated fatty acid supplementation (n-3 LCPUFA) for treatment of Autism Spectrum Disorder (ASD) is popular. The results of previous systematic reviews and meta-analyses of n-3 LCPUFA supplementation on ASD outcomes were inconclusive. Two meta-analyses were conducted; meta-analysis 1 compared blood levels of LCPUFA and their ratios arachidonic acid (ARA) to docosahexaenoic acid (DHA), ARA to eicosapentaenoic acid (EPA), or total n-6 to total n-3 LCPUFA in ASD to those of typically developing individuals (with no neurodevelopmental disorders), and meta-analysis 2 compared the effects of n-3 LCPUFA supplementation to placebo on symptoms of ASD...

The title compound, C14H13N3O5 (HMNP), was synthesized by the simple condensation of p-nitro-phenyl-hydrazine with de-hydro-acetic acid (DHA) in a 1:1 molar ratio in ethanol. HMNP has been characterized by using FT-IR, (1)H and (13)C NMR and UV-Vis spectroscopic and single-crystal X-ray diffraction techniques. The crystal packing reveals strong hydrogen bonds between the NH group and the carbonyl O atom of di-hydro-pyran-one moiety, forming chains along [101]. The thermal stability of the synthesized compound was confirmed by thermogravimetric analysis and it was found to be stable up to 513 K...

Prenatal docosahexaenoic acid (DHA) supply is important to ensure an adequate infant neurodevelopment. Several fat supplements with DHA under different chemical structures are available. There is an increased placental phospholipase activity at the end of pregnancy. The hypothesis of this study was to discern whether DHA consumption during pregnancy as phospholipids (PLs) could be more available for placental DHA uptake and fetal accretion than triglycerides (TGs) form. We aimed to evaluate maternofetal DHA status in pregnant rats fed with DHA as PL from egg yolk or TG from algae oil to determine which source might be most effective during pregnancy...

PURPOSE: The purpose of this double-blind, placebo-controlled study was to examine the effect of two fish oil supplements, one high in EPA (750 mg EPA, 50 mg DHA) and one low in EPA (150 mg EPA, 100 mg DHA), taken acutely as a recovery strategy following EIMD. METHODS: Twenty-seven physically active males (26 ± 4 year, 1.77 ± 0.07 m, 80 ± 10 kg) completed 100 plyometric drop jumps to induce muscle damage. Perceptual (perceived soreness) and functional (isokinetic muscle strength at 60° and 180° s(-1), squat jump performance and countermovement jump performance) indices of EIMD were recorded before, and 1, 24, 48, 72, and 96h after the damaging protocol...

Thraustochytrium sp. 26185 accumulates a high level of docosahexaenoic acid (DHA), a nutritionally important ω-3 very long chain unsaturated fatty acid (VLCPUFA) synthesized primarily by polyunsaturated fatty acid (PUFA) synthase, a Type I polyketide synthase-like mega-enzyme. The PUFA synthase in this species comprises three large subunits each with multiple catalytic domains. It was hypothesized that among these domains, ketoacylsynthase (KS) domains might be critical for catalyzing the condensation of specific unsaturated acyl-ACPs with malonyl-ACP, whereby retaining double bonds in an extended acyl chain...

Rhodopsin is the visual photoreceptor of the retinal rod cells that mediates dim light vision and a prototypical member of the G protein-coupled receptor superfamily. The structural stability and functional performance of rhodopsin are modulated by membrane lipids. Docosahexaenoic acid has been shown to interact with native rhodopsin but no direct evidence has been established on the effect of such lipid on the stability and regeneration of rhodopsin mutants associated with retinal diseases. The stability and regeneration of two thermosensitive mutants G90V and N55K, associated with the retinal degenerative disease retinitis pigmentosa, have been analyzed in docosohexaenoic phospholipid (1,2-didocosa-hexaenoyl-sn-glycero-3-phosphocholine; DDHA-PC) liposomes...

: Fish oil (FO) has been shown to have beneficial effects in the body via incorporation into the membranes of many tissues. It has been proposed that omega-3 fatty acids in FO may increase whole body resting metabolic rate (RMR) and fatty acid (FA) oxidation in human subjects, but the results to date are equivocal. The purpose of this study was to investigate the effects of a 12 week FO supplementation period on RMR and substrate oxidation, in comparison to an olive oil (OO) control group, in young healthy males (n = 26; 22...
