Poly(N-vinylimidazole), PVIm, gels were prepared by gamma-irradiation polymerization of N-vinylimidazole in aqueous solutions as an affinity gel for glucose oxidase (GOx). These affinity gels with a water swelling ratio of 1800% for plain polymeric gel and between 30-80% for Cu(II) and Co(II)-chelated gels at pH 6.0 in phosphate buffer were used in the GOx adsorption studies. Maximum metal ion ...

Abstract The current work aims to evaluate the growth rate, molecular patterns and biological activities of Arthrospira platensis cultivated in culture enriched with different chelated minerals (Fe, Zn, Cu, Mn, Mg) leather protein hydrolysates (LPHs) glycine addition determine phytochemical contents modified Zarrouk medium. Also, study profile variations (using SDS-PAGE, Comet assay, SCOT-PCR) ...

Multinuclear NMR studies of five-membered-ring amine chelated aryllithium reagents 2-lithio-N,N-dimethylbenzylamine (1), the diethylamine and diisopropylamino analogues (2, 3), and the o-methoxy analogue (4), isotopically enriched in (6)Li and (15)N, have provided a detailed picture of the solution structures in ethereal solvents (usually in mixtures of THF and dimethyl ether, ether, and 2,5-di...

This study was conducted in Abu-Khaseb –basra Province season 2010 to the effect of foliar fertilization by iron that spray chelated two concentrations (20 and 40 ppm) addition control treatment

BACKGROUND Hoof lesions are very common among sows and have been associated with lameness, early removal and compromised welfare and productivity. Although housing conditions and management can have an external effect on hoof health status, the role of trace mineral intake is vital in developing hoof structure and integrity. Therefore, the objective of this study was to investigate the effect o...

Nitrogen is an important element in the life of a plant. A wide range of nitrogen-containing compounds is available in the world market, with different formulations and efficiencies. Urea is present in most fertilizer applications; however, nano-nitrogen products are becoming popular although there is only limited information on their field efficiency. Thus, this paper studied the foliar applic...

In the title hetero-dinuclear complex, [CuSm(C(22)H(24)N(2)O(4))Cl(3)(CH(3)OH)(2)], the Cu(II) cation is N,N',O,O'-chelated by a 6,6'-dimeth-oxy-2,2'-[cyclo-hexane-1,2-diylbis(nitrilo-methanylyl-idene)]diphenolate ligand, and one Cl(-) anion further coordinates to the Cu(II) cation to complete the distorted square-pyramidal coordination geometry, while the Sm(III) cation is chelated by four O a...

Chelation is a bonding formed between a metal ion and legend. Chelating improves the absorption of the mineral from the digestive tract. The level of chelated minerals in livestock feeding is typically added at 25-30% of the total mineral in a feed. Chelated minerals have improvement in reproduction, health, soundness and growth. Natural feed with strong chelating properties includes dry melt r...
