OBJECTIVE We aimed to evaluate the sensitivity of tuberculin skintest (purified protein derivative-PPD) by topical zinc application on test site to improve diagnostic reliability. METHODS We performed this study in 100 children aged 6-14 years, and plasma zinc levels were analyzed after 10-12 hours fasting. After PPD, we applied 40% zinc oxide cream on one forearm and placebo on the other for...

In this study, we investigated the effect of vesicular zinc on ischemic neuronal injury. In cultured neurons, addition of a low concentration (under 100 microM) of zinc inhibited both glutamate-induced calcium influx and neuronal death. In contrast, a higher concentration (over 150 microM) of zinc decreased neuronal viability, although calcium influx was inhibited. These results indicate that z...

INTRODUCTION Zinc is an essential trace element for human nutrition, and its deficiency is associated with anorexia, poor food efficiency, growth retardation, and impaired neurological and immune systems. The zinc-deficiency rate is particularly high in many disease states, such as with end-stage renal disease patients undertaking hemodialysis. The aim of this study was to determine the effect ...

Twisted stainless steel wires are used as wire electrodes for electrospinning the polyvinyl alcohol (PVA)/zinc citrate nanofiber mats. The morphology and diameter of the nanofibers in PVA/zinc citrate nanofiber mats are evaluated. We measured the antibacterial efficacy against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) of the nanofiber mats. We also examined the cell adhes...

A novel zinc oxide - agar nanocomposite was successfully synthesized using zinc chloride as a precursor. The nanocomposite was prepared using a domestic microwave oven. The prepared nanocomposites have been characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and UV- visible spectroscopy. The crystalline properties...

the objective of the present study was to assess the combined effects of drought stress and foliar application of zinc and manganese on seed quality of red bean (naz variety) during the accelerated aging test. the experiment was carried out as split factorial in a randomized complete block design (rcbd) with three replications at the research farm of shahrekord university during 2010-2011. drou...

This study was conducted to determine the effects of various doses and particle sizes (micro or nano) of dietary zinc and zinc oxide on growth performance, serum enzyme activities, carcass characteristics, and zinc requirements in Japanese quails. A total of 576 day-old Japanese quails (both sexes) were housed in 36 deep litter floor pens. Birds received a basal corn–soybean meal diet that was ...
