The Ag, Co, Cr, Fe, Hg, Rb, Sb, Sc, Se, and Zn contents in normal tissue (n=37) and adenocarcinoma (n=37) of the human prostate gland were investigated using non-destructive instrumental neutron activation analysis with high resolution spectrometry of long-lived radionuclides. Mean values (M  SΕΜ) for content (mg/kg, dry mass basis) of trace elements in adenocarcinoma were: Ag – 0.2420.039, C...

Investigations on the accumulation of heavy metals five of the most commercially important fishes in the Parangipettai coastal waters were selected and analyzed for the Zn, Pb, Cr, Co and Cd concentrations in the muscles. The results revealed that the Cr and Zn concentrations were the highest; followed by Pb<Cd<Co being the lowest in the five species of fish tissue. The muscle concentrations of...

Thermal reactions of MnCl(DPyP) (DPyP = 5,15-di(4-pyridyl)-10,20-diphenylporphyrin) as a metalloligand with Co(II) and Zn(II) ions in dimethylformamide led to neutral one-dimensional (1D) double chain dipyridyl-porphyrin-based porous coordination polymers (PCPs), Co3(DPyP)3·4DMF (I) and Zn3(DPyP)3·2DMF·4H2O (II). Both PCPs were structurally characterized by X-ray crystallography. Particularly, ...

A series of high-quality M2(BDC)2(DABCO) metal-organic frameworks (abbreviated as M-DABCO; M=Zn, Co, Ni, Cu; BDC=1,4-benzene dicarboxylate; DABCO=1,4-diazabicyclo[2.2.2]octane), were synthesized by using a solvothermal (SV) method, and their catalytic activity for the cycloaddition of CO2 to epoxides in the absence of a co-catalyst or solvent was demonstrated. Of these metal-organic frameworks ...

Electrodeposition of Ni-Co-Fe-Zn alloys was done in a chloride ion solution with the presence and absence of a Permanent Parallel Magnetic Field (PPMF). The PPMF was applied parallel to the cathode surface. The deposition profile was monitored chronoamperometrically. It was found that the electrodeposition current was enhanced in the presence of PPMF (9 T) compared to without PPMF. The percenta...

The possibility of using freshwater Ulva (Chlorophyta) as a bioaccumulator of metals (Co, Cr, Cu, Mn and Zn) in lake and river water was examined weekly in the summer of 2010 in three types of samples: the water, the sediment and the thalli of Ulva. Samples of freshwater Ulva were collected from two aqueous ecosystems lie 250 km away from the basin of the Baltic Sea and 53 km from each other. A...

Oxidative stress is implicated in Parkinson's disease (PD). Metallothioneins (MT), cytochrome P450 IIE1 (CYP2E1) and glutathione S-transferases alpha4-4 (GSTA4-4) are involved in oxidative stress-mediated damage. Altered dopamine transporter (DAT) and vesicular monoamine transporter-2 (VMAT-2) are also documented in PD. The present study was undertaken to investigate the effect of Zn and PQ co-...

Three hybrid organic-inorganic coordination polymers with benzenepentacarboxylate (BPCA) linkers, [Co3(C6H(COO)5)(OH)(H2O)3] (1-Co), [Zn3(C6H(COO)5)(OH)(H2O)3] (2-Zn), and [Co5(C6H(COO)5)2(H2O)12].(H2O)12 (3-Co), were synthesized hydrothermally and were characterized structurally and magnetically. 1-Co and 2-Zn are isostructural [C2/c; Z=8; 1-Co, a=19.5350(6) A, b=10.4494(4) A, and c=13.2353(5)...

background: sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. this study was carried out for assessing co, ni, and zn in sediment samples of mighan wetland using geo-accumulation index in 2013. methods:the sediment samples were taken from 11 stations. the samples were subjected to bulk digest...

phthalocyanine complexes of cu, co, ni, fe, zn, pd, pt and ru have been synthesized from reaction between phthalonitrile and proper metal salts upon exposure to microwave irradiation under solvent-free conditions and considerably reduced reaction times.
