Through the microwave assisted fast synthesis method, Zinc Magnesium Oxide nanocomposite was prepared. Zinc Magnesium Oxide nanocomposite heated at 500oC was used for further structural, optical and antibacterial studies. The Debye Scherrer equation was used to calculate the average particle size of the nanocomposite. The optical characterization of the oxide nanocomposite was carried out by UV...
INTRODUCTION: Many trace elements play important roles in activating or inhibiting enzymatic reactions, by competing with other elements and metal proteins for binding sites, by affecting the permeability of cell membranes and by other mechanisms. They play important roles in the oxidant/antioxidant balance. As such, trace elements are thought to be involved directly or indirectly in the pathog...
OBJECTIVE To estimate the levels of trace elements in children with inflammatory bowel disease (IBD). DESIGN Prospective cross sectional study. SETTING Gastroentrology Unit, Great Ormond Street Children's Hospital, London, UK. SUBJECTS Seventy four children with inflammatory bowel disease confirmed endoscopically and histologically (38 ulcerative colitis and 36 Crohn's disease) and 40 age...
BACKGROUND Trace elements play important nutritional roles in neonates. Our objective was to examine whether there are differences in maternal/neonatal serum trace element concentrations between mature infants and premature infants. METHODS During 2012, 44 infants born at National Center for Global Health and Medicine, Tokyo, Japan, were enrolled. Serum samples were collected to measure serum...
(h) Controlled-release glass boluses (35 g) for use in sheep. The bolus contains by weight 13.4% copper. 0.5% cobalt and 0.3% selenium in a soluble glass matrix. (i) Sustained-release rumen bolus (80 g) for cattle. The bolus is composed of a compressed mixture of copper. cobalt. selenium. manganese. zinc. iodine and vitamins A. D and E. The round end of one bolus has been removed to show the 25...
BACKGROUND Traumatic brain injury (TBI) is one of the leading causes of disability and death among young people. Although much is already known about secondary brain damage the full range of brain tissue responses to TBI remains to be elucidated. A population of neurons located in cerebral areas associated with higher cognitive functions harbours a vesicular zinc pool co-localized with glutamat...
zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in hypericum perforatum cell suspension culture. high performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in h. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...
This research was conducted to evaluate effects of mycorrhiza fungi and nano zinc oxide on agro physiological traits of wheat under salinity stress based on factorial experiment according complete randomized block design with three replications under greenhouse condition at 2014. Treatments included salinity in three levels [no-salt (S0) or control, salinity 40 (S1) and 80 (S2) mM NaCl], two le...
Application of zinc can improve the tolerance and resistance of plants especially sunflower to environmental stresses and be effective on kernel set and yield. To investigate the effects of zinc oxide nanoparticles on the length, effective period, the rate of kernel filling and kernel weight in sunflower cultivars, a factorial experiment based on randomized complete block design with three repl...
This study was conducted to determine the nutritional status of maize cultivated lands and plant in Sanliurfa province term selenium micro elements. For this purpose, samples soil plants were taken from Akcakale, Ceylanpinar, Harran Viransehir districts. Texture, reaction, electrical conductivity, CaCO3, organic matter, available selenium, exchangeable iron, zinc, copper, manganese boron analys...
