Owing to its high technological importance for optoelectronics, zinc oxide received much attention. In particular, the role of defects on its physical properties has been extensively studied as well as their thermodynamical stability. In particular, a large concentration of Zn vacancies in ZnO bulk materials is so far considered highly unstable. Here we report that the thermal decomposition of ...

The effect of foliage sprayed zinc sulfate on berry development of Vitis vinifera cv. Merlot growing on arid zone Zn-deficient soils was investigated over two consecutive seasons, 2013 and 2014. Initial zinc concentration in soil and vines, photosynthesis at three berry developmental stages, berry weight, content of total soluble solids, titratable acidity, phenolics and expression of phenolics...

OBJECTIVE Our aim was to determine if NO prevents mitochondrial oxidant damage by mobilizing intracellular free zinc (Zn(2+)). METHODS Zn(2+) levels were determined by imaging enzymatically isolated adult rat cardiomyocytes loaded with Newport Green DCF. Mitochondrial membrane potential (DeltaPsi(m)) was assessed by imaging cardiomyocytes loaded with tetramethylrhodamine ethyl ester (TMRE). ...

BACKGROUND Diarrhea causes an estimated 2.5 million child deaths in developing countries each year, 35% of which are due to acute diarrhea. Zinc and copper stores in the body are known to be depleted during acute diarrhea. Our objectives were to evaluate the efficacy of zinc and copper supplementation when given with standard treatment to children with acute watery or bloody diarrhea. METHODS...

BACKGROUND Although the importance of adequate zinc intake has been known for decades, the estimated global prevalence of zinc deficiency remains high. This substantiates the need for a specific and sensitive status assessment tool. OBJECTIVE The objective was to evaluate erythrocyte zinc transporters as candidate molecules with the potential of being a biomarker of dietary zinc status in hum...
