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)
An increased inflammatory response and deficient synthesis of neurotrophic factors (NTFs) may contribute to the etiology of depression. However, the interrelationship between inflammation and NTFs is unknown. Recently, ethyl-eicosapentaenoate (EPA) has been used to treat depression. The mechanism by which EPA benefits depression is also unclear. Using the(More)
Recent evidence has suggested that an imbalance between membrane (n-3) and (n-6) fatty acids may contribute to the etiology of autoimmune and neurodegenerative diseases. In this study, the mechanisms by which eicosapentaenoic acid (EPA), gamma-linolenic acid (GLA), and arachidonic acid (AA) modulate neurotransmitters, behavior, and brain inflammation were(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)
Essential fatty acids are important constituents of the brain. There is evidence that levels in blood of certain essential fatty acids and their eicosanoid derivatives may be abnormal. We now report that in the frontal cortex of schizophrenic patients there are significant differences from normal in the fatty acid composition of phosphatidylethanolamine.(More)
The pathomechanisms involved in the neuronal dysfunction in Huntington disease (HD) are still unresolved and may be heterogeneous. One potential mechanism might be related to the induction of mitochondrial dysfunction in the CNS. This might lead firstly to neuronal dysfunction and finally to the activation of apoptotic pathways. Several compounds, which(More)
We have examined the composition of the essential fatty acids in the plasma phospholipid fractions of 98 patients with histologically proven bladder cancer. These patients were attending hospital for regular follow-up by check cystoscopy. Patients were divided into two groups, depending on the cystoscopic findings, of either active (tumour recurrence seen)(More)
It has been proposed that schizophrenia is a prostaglandin-deficiency disease and also that it is a disease of prostaglandin excess. New evidence is reviewed which suggests that 'classic' schizophrenia is due to a specific deficiency of prostaglandin E1 while certain toxic and vitamin-deficiency psychoses may be due to a broader spectrum of prostaglandin(More)
Plasma phospholipid and cholesterol ester fatty acid levels were measured in samples from normal individuals, schizophrenics, and patients with affective and paranoid disorders in Japan. The schizophrenics were divided into groups with normal and reduced platelet sensitivity to the aggregation-inhibiting effects of prostaglandin (PG) E1. As in samples from(More)
