this experiment was conducted in order to evaluate the effects of foliar application of ordinary and nano-particles of zinc oxide on the response of corn to salinity. treatments included two corn genotypes (seed mass and sc 704), three spray levels (zinc oxide, nano-sized zinc oxide, and a spray of water treatment) and three salinity levels (0, 75 and 150 mm nacl). shoot dry matter was decrease...
background: there have been several studies done on the role of metals in the occurrence of multiple sclerosis (ms) disease, but their roles have not been confirmed yet. because of the lack of information on this issue, this study compared the serum level of copper and zinc in ms patients with their levels in a control group. methods: this was an analytical, cross-sectional study...
To investigate the impact of calcium, magnesium, zinc, and copper in blood and seminal plasma on semen parameters, 107 fertile and 103 subfertile males provided a standardized blood and semen specimen. Total calcium and magnesium concentrations were determined with colorimetric end point assay procedures. Zinc and copper were determined by flame atomic absorption spectrophotometer (AAS). Semen ...
Zinc deficiency is clearly teratogenic in animals (1). The catabolism of maternal tissues during pregnancy, however, seems to protect the fetus from the teratogenic effects of hypozincemia (2). In humans, most evidence suggesting the importance of zinc during pregnancy comes from patients with acrodermatitis enteropathica, an inherited severe zinc deficiency state. These patients have spontaneo...
apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. infants and young children are very susceptible to amount of trace elements. copper and zinc are two elements that add in infant food. lead and cadmium are heavy metals that enter to food chain unavoidably. dpasv is a benefit and applicable method for measurement of trace elements in food produc...
Wilson’s disease (WD) is an inherited autosomal recessive disorder that lead to copper accumulation in the liver, brain, cornea, and other organs [1]. WD is treatable by life-long decoppering therapy with the aim of removing excess copper and preventing re-accumulation. This is accomplished with two main groups of drugs: chelating agents, including d-penicillamine (DPA) and trientine, that prom...
Introduction: Copper and zinc play a key role in oxidative reactions and in vivo studies have shown their different effects. In this study we examined the influence of exposure to copper and zinc on catalase and superoxide dismutase (SOD) activities in erythrocytes, total serum antioxidant capacity and malondiadehyde (MDA) production of copper industry workers. Methods: In the present study...
The interaction of copper oxide nanoparticles and copper ions and proteinase K from Tritirachium album Limber has been investigated employing UV spectroscopy and kinetics measurements. The aim of this study was to evaluate the effect of nanoparticles of CuO for proteinase K. In this paper we compare the effect of copper oxide nanoparticles with the effect of copper ions on proteinase K sta...
Abstract Nanotechnology is a completely unique branch of technology that offers with substances in very small size between (1–100 nm) various crystal shapes. Metals have ability to produce large number oxides. These metal oxides play major role many areas chemistry, physics, material science and food science. In this research, Zinc Oxide (ZnO) Copper (II) oxide nanoparticles were synthesized vi...
