Stimulation of the activities of hepatic fatty acid oxidation enzymes by dietary fat rich in alpha-linolenic acid in rats

open access: yesJournal of Lipid Research, 1996
The activities of hepatic fatty acid oxidation enzymes in rats fed perilla oil rich in alpha-linolenic acid (alpha-18:3) were compared with those fed saturated fats or safflower oil (the mixture of safflower oil and olive oil, 94:8, w/w) containing the ...

Visual evoked potentials in succinate semialdehyde dehydrogenase (SSADH) deficiency [PDF]

open access: yes, 2009
In mammals, increased GABA in the central nervous system has been associated with abnormalities of visual evoked potentials (VEPs), predominantly manifested as increased latency of the major positive component P100.

Identification of metabolites from peroxisomal beta-oxidation of prostaglandins.

open access: yesJournal of Lipid Research, 1990
We have recently shown that isolated rat liver peroxisomes can chain-shorten prostaglandin F2 alpha and prostaglandin E2 to tetranor-metabolites. In the present report dinor-metabolites of these two prostaglandins were also identified, suggesting that ...

Effect of the Enrichment of Corn Oil With alpha- or gamma-Tocopherol on Its In Vitro Digestion Studied by 1H NMR and SPME-GC/MS; Formation of Hydroperoxy-, Hydroxy-, Keto-Dienes and Keto-E-epoxy-E-Monoenes in the More alpha-Tocopherol Enriched Samples

open access: yesAntioxidants, 2020
The aim of this study is the analysis of the in vitro digestion of corn oil, and of the effect of its enrichment with three levels of gamma- and alpha-tocopherol, by using, for the first time, 1H nuclear magnetic resonance (1H NMR) and a solid phase ...

Biodegradation of alkyl branched aromatic alkanoic naphthenic acids by Pseudomonas putida KT2440 [PDF]

open access: yes, 2012
The majority of the world's crude oil reserves consist of highly biodegraded heavy and super heavy crude oils and oil sands that have not yet been fully exploited.

Depolymerization of biorefinery lignin by improved laccases of the white-rot fungus Obba rivulosa [PDF]

open access: yes, 2021
Fungal laccases are attracting enzymes for sustainable valorization of biorefinery lignins. To improve the lignin oxidation capacity of two previously characterized laccase isoenzymes from the white-rot fungus Obba rivulosa, we mutated their substrate ...

Antioxidant and prooxidant activity of alpha-tocopherol in human plasma and low density lipoprotein.

open access: yesJournal of Lipid Research, 1996
Alpha-Tocopherol is a classical lipophilic antioxidant well known as a scavenger of free radicals in a hydrophobic milieu. However, it can develop both anti- and prooxidant activity in isolated low density lipoprotein (LDL).

Alpha oxidation of cerebronic acid in brains from scorbutic and ascorbic acid-supplemented guinea pigs [PDF]

open access: yesBiochemical and Biophysical Research Communications, 1971
Abstract Brains from scorbutic and ascorbic acid supplemented guinea pigs were used as a source of enzyme for decarboxylation of [1-14C-]-2-hydroxytetracosanoic acid. Both in the 10,000xg supernatant fraction and the recombined 110,000xg pellet and supernatant fractions, decarboxylation was greatly reduced.

Effects of Alpha- Tocopherol on the Velocity of Low Density Lipoprotein Oxidation by Cupric Ions [PDF]

open access: yesActa Medica Iranica, 2010
We studied the effect of different concentrations of alpha-tocopherol on in vitro cupric ions induced oxidation of low density lipoproteins (LDL). Human native LDL (50 µg protein/ml) oxidation was induced by 10 µmol/L of CuSO4.

Effect of oral supplementation with D-alpha-tocopherol on the vitamin E content of human low density lipoproteins and resistance to oxidation.

open access: yesJournal of Lipid Research, 1991
Twelve clinically healthy subjects participated in a vitamin E supplementation study. Eight were given daily dosages of 150, 225, 800, or 1200 IU RRR-alpha-tocopherol for 21 days (two persons per dose) and four received placebo.
