Research ArticleOpen accessIn the abstractBiosensor 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 · 8,602 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAndrogen Receptor in Macrophages of Male Rat is Greater Than in FemaleKazem Ahmadi, Alan B. McCrudenThe presence and possible sex differences of androgen receptor in peritoneal macrophages was investigated using immunomagnetic beads. Macrophages were incubated with different concentrations of [3H]-5αDHT in the presence or absence of a 100 fold excess of unlabelled 5α-DHT. Labelled cells were separated from unbound steroid by immunomagnetic beads coated with anti-rat macrophage antibody. The binding identified in the rat macrophages … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,834 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,783 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProduction of Silica-refractory Bricks from White SandGazze AlmarahleAt present, no refractories are produced in Jordan, but large quantities are imported for use in the lining of furnaces and kilns in the metallurgical industries.The aim of this study is to initiate a program of research for production of silica-refractory bricks from local materials.The raw material, which has been used in this study was white sand. This sand contains … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,340 accessesView PDF Cite
