Fabrication of magnetic iron oxide-supported copper oxide nanoparticles (FeO/CuO): modified screen-printed electrode for electrochemical studies and detection of desipramine.

The present investigation examines a sensitive electrochemical technique to detect desipramine through FeO/CuO nanoparticles (NPs). FeO/CuO NPs were synthesized a coprecipitation procedure, and the products were characterized energy disperse spectroscopy, X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and vibrating sample magnetometer. The voltage-current curve and differential pulse voltammetry examinations of FeO/CuO-modified screen-printed electrode (FeO/CuO/SPE) were followed by the determination of electro-catalytic activities toward desipramine oxidation in a phosphate buffer solution (pH = 7.

Determination of reference values for intraocular pressure and Schirmer tear test in clinically normal ostriches (Struthio camelus).

The purpose of this study was to establish normal physiologic reference values for intraocular pressure (IOP) and Schirmer tear test (STT) results in clinically normal ostriches (Struthio camelus). Twenty ostriches of both sexes, 10 juveniles (1.5-2 yr of age) and 10 adults, were included in this study.
