the concentration of cu, mn, ni and zn were determined in tomatoes and onions samples using atomic absorption spectrometry. a total of 32 samples each of tomatoes and onions were collected from the exposed and control sites for analysis. the trace metals (cu, mn, ni and zn) concentration in tomatoes wee found to be 6.2406, 6.5521 , 5.7375 and 8.9297 mg/kg-1, respectively. while those of onions ...

an experiment was conducted in the experimental field of seed and plant improvement institute in karaj for three consecutive cropping seasons, 2001-2003, to study the effects of eight different fertilizer treatments including some microelements on grain yield and protein content of a bread wheat cultivar pishtaz. the experiment was in a rcbd with three replications.eight fertilizer treatments w...

High-resolution imaging techniques have increased the detection rate of adrenal incidentaloma. We developed a method of liquid chromatography-tandem mass spectrometry (LC-MS/MS) for detection of plasma free metanephrine (MN) and normetanephrine (NMN) and evaluated its analytical performance and clinical efficacy in differential diagnosis of adrenal incidentaloma. After solid-phase extraction, c...

BACKGROUND AND OBJECTIVES Long-term contact with mercury may induce membranous nephropathy (MN); however, the clinical pathologic features and pathogenesis of mercury-induced MN have not been investigated. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The present study retrospectively evaluated 11 cases of mercury-induced MN to analyze its causes and its clinical and pathologic features. RE...

gc-fid and hplc-dad were developed for determination of menadione (mn) and menadione sodium bisulphite (msb). by means of each method, quantitative analysis of msb in commercial pharmaceutical was performed in both direct analysis of msb and analysis of mn by converting msb to mn with sodium carbonate. gc-fid method was carried out on the hp-5 capillary column using nitrogen gas. hplc-dad metho...

Capsule application of Diamidino Yellow (DY) to the cut end of the sciatic nerve immediately followed by capsule application of Fast Blue (FB) resulted in approximately 95% double-labelled dorsal root ganglion neurones (DRGn) and motoneurones (Mn). Nerve injection of DY followed either immediately or 2 months later by capsule application of FB resulted in approximately 90% double-labelled DRGn ...

To prevent Cr poisoning of the cathode and to retain high conductivity during solid oxide fuel cell (SOFC) operation, Cu or La doped Co-Mn coatings on a metallic interconnect is deposited and followed by oxidation at 750 ◦C. Microstructure and composition of coatings after preparation and oxidation is analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). High energy micro ...
