Despite being critical for normal brain function, the pools that supply docosahexaenoic acid (DHA) to the brain are not agreed upon. Using multiple kinetic models in free-living adult rats, we first demonstrate that DHA uptake from the plasma non-esterified fatty acid (NEFA) pool predicts brain uptake of DHA upon oral administration, which enters the plasma NEFA pool as well as multiple plasma ...

Little is known about the interrelationships between maternal and infant erythrocyte-DHA, milk-DHA and maternal adipose tissue (AT)-DHA contents. We studied these relationships in four tribes in Tanzania (Maasai, Pare, Sengerema and Ukerewe) differing in their lifetime intakes of fish. Cross-sectional samples were collected at delivery and after 3 d and 3 months of exclusive breast-feeding. We ...

Glycerol is the main osmoticum of the unicellular green alga Dunaliella [1-4]. During the process of osmoregulation this solute has to be synthesized or degraded efficiently depending on the extent and direction of changes in the salinity of the external medium. Synthesis of glycerol starts from DHAP [5]. A glycerol-3-phosphate dehydrogenase (EC 1.1.1.8) reduces DHAP to glycerol-3-phosphate and...

(2014) Effect of varying dietary levels of LC-PUFA and vegetable oil sources on performance and fatty acids of Senegalese sole post larvae: Puzzling results suggest complete biosynthesis pathway from C18 PUFA to DHA, Comparative Biochemistry and Physiology-Part B: Biochemistry and Molecular Biology, 167, pp. 51-58. NOTICE: this is the author's version of a work that was accepted for publication...

Pyroligneous acid (PA) is often used in agriculture as a plant growth and yield enhancer. However, the influence of PA application on soil microorganisms not studied. Therefore, this study, we investigated effect (0.01–5% w/w soil) microbial diversity two different soils. At end eight weeks incubation, community dynamics were determined by Illumina-MiSeq sequencing 16S rRNA gene amplicons. The ...

Coadministration of dihydroartemisinin-piperaquine (DHA-PQ) with fat may improve bioavailability and antimalarial efficacy, but it might also increase toxicity. There have been no studies of these potential effects in the pediatric age group. The tolerability, safety, efficacy, and pharmacokinetics of DHA-PQ administered with or without 8.5 g fat were investigated in 30 Papua New Guinean childr...

The present study examined: (i) age-induced regional changes in fatty acid composition of brain phospholipids; (ii) alpha-linolenic acid deficiency-induced regional depletion and recovery of DHA in the brain. DHA and arachidonic acid (AA) did not distribute evenly in the brain. In weaning and adult rats, the region with the highest DHA percentage was the cortex whereas the medulla had the lowes...

Docosahexaenoic acid (DHA) is the major polyunsaturated fatty acid (PUFA) in the brain and a structural component of neuronal membranes. Changes in DHA content of neuronal membranes lead to functional changes in the activity of receptors and other proteins which might be associated with synaptic function. Accumulating evidence suggests the beneficial effects of dietary DHA supplementation on ne...

The health benefits of the (n-3) PUFA, EPA, and DHA have created a demand for fish and fish oil, the main sources of these PUFA. Production animals, such as poultry, are potential alternate and sustainable sources of EPA and DHA, provided these fatty acids can be synthesized from plant-derived α-linolenic acid [ALA, 18:3(n-3)]. Because elongases are potential control points in the conversion of...
