Zn2+ ions are essential for the normal processing and storage of insulin and altered pancreatic insulin content is associated with all forms of diabetes mellitus. Work of the past decade has identified variants in the human SLC30A8 gene, encoding the zinc transporter ZnT8 which is expressed highly selectively on the secretory granule of pancreatic islet β and α cells, as affecting the risk of T...

Zinc is an imperative micronutrient required for optimum plant growth. Zinc solubilizing bacteria are potential alternatives for zinc supplementation and convert applied inorganic zinc to available forms. This study was conducted to screen zinc solubilizing rhizobacteria isolated from wheat and sugarcane, and to analyze their effect on wheat growth and development. Fourteen exo-polysaccharides ...

Zinc is essential for the growth and development of plants, but in excessive amounts soil it can be toxic them. Its mobility depends part on organic matter content soil. The aim study was to investigate effect application increasing zinc (200, 400 600 mg Zn·kg−1 soil) together with various forms fertilizer (cattle manure, chicken manure spent mushroom substrate) yield cocksfoot uptake this meta...

Ethylzinc 2,6-bis(p-tolyl)benzoate converts between two forms in solution. Through NMR spectroscopic techniques and X-ray crystallography, the species in equilibrium were identified as [Zn2(ArTolCO2)2(Et)2(THF)2] (1), [Zn2(ArTolCO2)3(Et)(THF)] (2), and diethyl zinc (ArTol = 2,6-bis(p-tolyl)phenyl). The equilibrium provides a model for understanding the speciation between doubly and triply m-ter...

objective: the present study was performed to compare the antioxidant effect of two different doses of zinc on lipid oxidation in type 2 diabetic patients. materials and methods: this double-blind, randomized controlled trial was conducted on 60 type 2 diabetic patients in yazd diabetes research center in 2008. the subjects were randomly allocated to receive zinc sulfate (iran, alhavi) either 2...

abstract   objective: to determine the effect of oral zinc sulfate supplementation given with coamoxiclav when compared with coamoxiclav alone for treatment of otitis media with effusion (ome). the efficacy of the drug was assessed 3 and 6 weeks after administration .   methods: in a double-blind, randomized trial 4 to 14 years old children with ome who referred to ear, nose and throat clinic, ...

Nanoparticles may contain unusual forms of structural disorder that can substantially modify materials properties and thus cannot solely be considered as small pieces of bulk material. We have developed a method to quantify intermediate-range order in 3.4-nanometer-diameter zinc sulfide nanoparticles and show that structural coherence is lost over distances beyond 2 nanometers. The zinc-sulfur ...

Amyloid plaques consisting of aggregated Aβ peptide are a hallmark of Alzheimer's disease. Among the different forms of Aβ, the one of 42aa length (Aβ42) is most aggregation-prone and also the most neurotoxic. We find that eye-specific expression of human Aβ42 in Drosophila results in a degeneration of eye structures that progresses with age. Dietary supplements of zinc or copper ions exacerbat...
