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 ...
Antioxidant and chemopreventive properties of polyphenolic compounds derived from Greek legume plant extracts
(2008)
Recently, phytochemical compounds present in legumes have gained a lot of interest because they are considered to be possible chemopreventive agents. In the present study, 14 polyphenolic compounds were extracted and ...
Inhibition of human and ovine acrosomal enzymes by tannic acid in vitro
(2001)
The effect of tannic acid, a common flavonoid, on the acrosin and plasminogen activator activity and plasmin activity of human and ram spermatozoa was evaluated. Acrosin and plasminogen activator activity were determined ...
Dietary administration of tannic acid lowers plasminogen activator activity in the liver of C3H hepatoma bearing male mice
(2000)
Background: This study was undertaken to investigate if low-dose dietary administration of tannic acid exerts its chemopreventative activity on hepatocarcinogenesis in male C3H mice through changes of plasminogen activator ...
A modified method for the detection of differentially expressed mRNAs without using radioactivity
(2001)
We present here a modification of the original differential display approach using a single oligo(dT) primer for the reverse transcription reaction (instead of the various oligo(dT)NM primers that subdivide the pool of ...
Activity of grape extracts from Greek varieties of Vitis vinifera against mutagenicity induced by bleomycin and hydrogen peroxide in Salmonella typhimurium strain TA102
(2006)
Several in vivo and in vitro studies have shown that grape extracts could prevent certain steps in carcinogenesis and a few mechanisms have been proposed for this activity. In this study, the potential antimutagenic activity ...
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 ...
