Resistance to mercuric ions in bacteria is conferred by mercuric reductase, which reduces Hg(II) to Hg(0) in the cytoplasmic compartment. Specific mercuric ion transport systems exist to take up Hg(II) salts and deliver them to the active site of the reductase. This short review discusses the role of transport proteins in resistance and the mechanism of transfer of Hg(II) between the mercury-re...

Long-standing diabetes can result in the development of a cardiomyopathy, which can be accompanied by myocardial fibrosis. Whereas exposure of cultured kidney and skin fibroblasts to high glucose (HG) is known to increase collagen synthesis, little is known about cardiac fibroblasts (CF). Therefore, we determined the influence of HG on CF functions, and the effects of losartan and vitamin E in ...

In the neutral title complex, [HgCl(2)(C(12)H(11)NO(3))], the Hg(II) ion is penta-coordinated by two Cl atoms, one N atom and two weakly coordinating O atoms from the methyl 2-(quinolin-8-yl-oxy)acetate ligand. The coordination around the Hg(II) ion may be described as highly distorted trigonal-bipyramidal. Centrosymmetric dimers are formed by an additional weak Hg⋯Cl inter-action, leading to a...

Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Atmospheric mercury concentrations were measured during two oceanographic cruise campaigns covering the Adriatic Sea, the first during the autumn in 2004 and the second in...

The mercury (II) complex, Hg (Meca2en)I2 (1), containing bidentate Schiff base ligand  Meca2en = N,N′-bis[(E)-2-benzylidenepropylidene]ethane-1,2-diamine, has been synthesized and characterized by elemental analyses (CHN) and 1H-NMR spectroscopy. The crystal structure of 1 was determined using single-crystal X-ray diffraction. Structural investigation shows that 1 crystallizes in a monoclinic s...

The combination of HgCl2 with the disulfide salt of 2-aminoethanethiol (cystamine dihydrogen dichloride) in water yields a two-dimensional chain {[HgCl4][(NH3CH2CH2S )2]}n (1). It consists of six-coordinate Hg in [HgCl4]n units with bridging and termainal Cl atoms. The disulfide groups, (NH3CH2CH2S )2 are held between the [HgCl4]n chain with weak S S interactions. The chlorides in the [HgCl4]n ...

2-(pyridine-2-yl)-N-p-chlorohydrazinecarbothioamide (HCPTS) was synthesized, characterized and successfully applied for the preconcentration of Cu(II), Ni(II), Zn(II), Cd(II), Co(II), Pb(II), Fe(II), and Hg(II) in water, blood, and urine samples prior to graphite furnace atomic absorption determination (GFAAS); Hg was determined by cold vapor technique. Under the optimum experimental conditions...
