The age-related decline in cognitive function has been associated with biochemical changes that can be attenuated following n-3 polyunsaturated fatty acid treatment. Dietary supplementation with docosahexaenoic acid (DHA) has been shown to reverse age-related changes in synaptic function. Here, lipidomic analyses were undertaken to examine changes in lipid(More)
BACKGROUND Preliminary evidence suggests beneficial effects of pure ethyl-eicosapentaenoate (ethyl-EPA) in Huntington disease (HD). METHODS A total of 135 patients with HD were randomized to enter a multicenter, double-blind, placebo-controlled trial on the efficacy of 2 g/d ethyl-EPA vs placebo. The Unified Huntington's Disease Rating Scale (UHDRS) was(More)
Ultra-pure ethyl-eicosapentaenoic acid (ethyl-EPA), a semi-synthetic ethyl ester of eicosapentaenoic acid, is associated with clinical improvement in motor functioning in Huntington's disease. The aim was to determine the extent to which it might reduce the rate of progress of cerebral atrophy. High-resolution cerebral magnetic resonance imaging scans were(More)
Chloroquine, quinine, procaine, quinidine and clomipramine behave as prostaglandin (PG) antagonists in a rat mesenteric vascular bed preparation. The ID50 concentrations were within the range of therapeutically effective human plasma levels in each case. Antagonism to PGE2 was studied in detail and seemed to be at least in part competitive. The drugs also(More)
Prostaglandin (PG) E1 plays a major role in the regulation of thymus development and T lymphocyte function and the evidence for this is reviewed. The production of PGE1 is dependent on nutritional factors with linoleic acid, gamma-linolenic acid, pyridoxine, zinc and vitamin C playing key roles. Inadequate intake of any one of these will lead to inadequate(More)
This study compared 48 hyperactive children with 49 age-and-sex-matched controls. Significantly more hyperactive children had auditory, visual, language, reading, and learning difficulties, and the birth weight of hyperactive children was significantly lower than that of controls (3,058 and 3,410 g, respectively; p less than 0.01). In addition,(More)
In the plasma phospholipids of a group of 50 young adults with atopic eczema, there was an elevation of cis-linoleic acid associated with a deficit of gamma-linolenic acid and of the prostaglandin precursors, dihomogammalinolenic acid and arachidonic acid. This suggests that atopics have a deficit in the function of the delta-6-desaturase enzyme which(More)
INTRODUCTION Icosapent ethyl (IPE) is a high-purity prescription form of eicosapentaenoic acid (EPA) ethyl ester. We evaluated IPE's effects on plasma and red blood cell (RBC) fatty acids (FA) and the relationship to triglyceride (TG) lowering. MATERIALS AND METHODS This was a predefined, exploratory analysis (N=229) of FA plasma concentration and RBC(More)
We have measured all the essential fatty acids (EFA) in plasma phospholipids in forty-one adults with atopic eczema and fifty normal controls. The major dietary n-6 EFA, linoleic acid, was significantly elevated, but all its metabolites, 18:3n-6, 20:3n-6, 20:4n-6, 22:4n-6, and 22:5n-6 were significantly reduced. The major dietary n-3 EFA, alpha-linolenic(More)
