The effects of a single bout of exercise on resting energy expenditure and respiratory exchange ratio
(2004)
We investigated the effects of a single bout of aerobic and resistance exercise of similar relative intensity and duration on resting energy expenditure (REE) and substrate utilisation. Ten young healthy males volunteered ...
Enzymatic oxidation of 2-phenylethylamine to phenylacetic acid and 2-phenylethanol with special reference to the metabolism of its intermediate phenylacetaldehyde
(2004)
2-Phenylethylamine is an endogenous constituent of the human brain and is implicated in cerebral transmission. This bioactive amine is also present in certain foodstuffs such as chocolate, cheese and wine and may cause ...
Contribution of aldehyde oxidase, xanthine oxidase, and aldehyde dehydrogenase on the oxidation of aromatic aldehydes
(2004)
Aliphatic aldehydes have a high affinity toward aldehyde dehydrogenase activity but are relatively poor substrates of aldehyde oxidase and xanthine oxidase. In addition, the oxidation of xenobiotic-derived aromatic aldehydes ...
Determination of xylazine and its metabolites by GC-MS in equine urine for doping analysis
(2004)
Xylazine and its main metabolites were detected in equine urine after a single-dose intravenous administration of 0.98 and 1.01 mg/kg body weight xylazine, respectively, in two horses, in order to be used for equine doping ...
Plant phenolics protect from bleomycin-induced oxidative stress and mutagenicity in Salmonella typhimurium TA102
(2004)
Antioxidants are deemed to be important against DNA damage and mutations induced by reactive oxygen species (ROS). An assay for the ability of plant phenolics to protect against mutations caused by bleomycin treatment in ...
Gas chromatographic - Mass spectrometric cardiotonic glycosides detection in equine urine doping analysis
(2004)
A screening method for the detection of cardiotonic glycosides in horse's urine is presented in this paper. This method is based on the detection by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-high ...
Metabolism of 2-phenylethylamine and phenylacetaldehyde by precision-cut guinea pig fresh liver slices
(2004)
2-Phenylethylamine is an endogenous constituent of human brain and is implicated in cerebral transmission. It is also found in certain foodstuffs and may cause toxic side-effects in susceptible individuals. Metabolism of ...
