Electronic structures of Zn(2+) and Cd(2+) thiolate clusters found in metallothioneins (MT) have been obtained using density functional theory. We have found that the inherent asymmetry of cluster architectures gives rise to seven distinct metal sites. Whereas the non-strained bond lengths of such tetrathiolate complexes are found to be 2.60 Å and 2.39 Å for Cd-S and Zn-S, in the MT clusters fo...

In the mononuclear title complex, [CdBr2(C20H17N3)(C3H7NO)], synthesized from the quinoline-derived Schiff base 2-(1H-indol-3-yl)-N-(quinolin-2-yl-methyl-ene)ethan-amine (IQME), the coordination geometry around the Cd(2+) atom is distorted trigonal bipyramidal, the axial positions being occupied by the quinoline N atom [Cd-N = 2.401 (3) Å] and one di-methyl-formamide O-atom donor [Cd-O = 2.399 ...

The title complex, [Cd(2)(C(8)H(7)O(3))(4)(C(20)H(22)N(4)O)(2)], forms a dimer of the paddle-wheel type, located on a crystallographic inversion centre. The Cd(II) ion is hexa-coordinated by four carboxylate O atoms [Cd⋯O = 2.280 (2)-2.404 (2) Å] from two chelating 4-methoxy-benzoate anions, and two N atoms [Cd⋯N = 2.313 (2) and 2.332 (2) Å] from one chelating 2,2'-dimethyl-3,3'-(oxydiethyl-ene...

Background. Despite strategies to reduce transmission, Clostridium difficile (CD) remains a leading cause of morbidity in health care settings. The aims of our study were (1) to determine if asymptomatic inpatient CD carriers can be liked by molecular epidemiology to other inpatients with CD infection (CDI) and (2) to determine if active surveillance testing (AST) criteria to identify inpatient...

Nanoparticles of Mn0.5Zn0.5-xCdxFe2O4 with x varying from x = 0.0 to 0.3 were prepared by wet chemical co-precipitation method. The structural and magnetic properties were studied by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM) and Electron Paramagnetic Resonance (EPR) technique. ...

Diffusion coefficients of Cd-humate complexes are dependent on pH and [Cd]/[Humic] Acid (HA)] ratio in a Cd-HA system. These two factors mainly control the mass transport and complexation kinetics of Cd that may influence bioavailability and toxicity of Cd species in environmental systems. Determination of diffusion coefficients of Cd-HA systems by Scanned stripping voltammetry and dynamic ligh...

The crystal structure of the title compound, [Cd(C7H5O3)2(C6H6NO)2(H2O)2]·2[Cd(C7H5O3)2(C6H6NO)(H2O)2]·4H2O, consists of two kinds of Cd(II) complexes (A and B) and lattice water mol-ecules. In complex A, [Cd(C7H5O3)2(C6H6NO)2(H2O)2], the Cd(II) cation is located on an inversion center and is coordinated by two salicylate anions, two nicotinamide (NA) ligands and two water mol-ecules in a sligh...

Oxidative tissue damage is considered an early sign of cadmium (Cd) toxicity and has been linked with carcinogenesis. Manganese(II)-at low doses, was found to act as a potent antioxidant against oxidative stress in different in vitro systems producing lipid peroxidation conditions. The present study investigates in vivo antioxidant effects of Mn(2+) pretreatment in acute Cd intoxication with re...

An inclusion complex consisting of a fluorescent phenylboronic acid (C1-APB) and beta-cyclodextrin (beta-CD) acts as a supramolecular saccharide sensor whose response mechanism is based on photoinduced electron transfer (PET). This study evaluated four kinds of cyclodextrins (alpha-CD, beta-CD, gamma-CD, and NH(2)-beta-CD) by comparing their pH profiles, and confirmed that beta-CD was the best ...
