Research ArticleOpen accessPhrase in the titleBiosensor Based on Xanthine Oxidase for Monitoring Hypoxanthine in Fish MeatHelena S. Nakatani, Luciane V. dos Santos, Cristiano P. Pelegrine et al.An amperometric enzyme electrode for the detection of hypoxanthine in fish meat is described. The hypoxanthine sensor was prepared from xanthine oxidase immobilized by covalent binding with glutaraldehyde and bovine serum albumin on a nafion-coated platinum disc electrode. The responses for hypoxanthine were obtained in 0.1 mol L-1 phosphate buffer (pH 7.0), at potential of 600mV vs Ag/AgCl. This biosensor … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 8,597 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsIn Vitro Interaction of 5-Hydroxytrptamine with Cytosolic Molybdenum Hydroxylases as a Potential Inhibitor for Initial Rates ActivitiesAbdullah M. Al-Mohizea, Abd El-Galil E. Amr, Mohamed A. Al-OmarProblem statement: The role of 5-HT has been investigated in many behavioral activities. Thus, studies using raphe lesion showed that 5-HT is involved in sleep, general activity levels, habituation, aggression, pain sensitivity and morphine analgesia, avoidance behavior, self-stimulation and water consumption. Approach: The metabolic interaction between serotonin (5- hydroxytrptamine) and indole-3-aldehyde and xanthine via aldehyde oxidase (EC 1.2.3.1) and xanthine … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,026 accessesView PDF Cite
