The increasing atmospheric CO(2) and heavy metal contamination in soil are two of the major environmental problems. Knowledge of the Cd stress coping mechanisms is needed to understand the regulation of the plants' metabolism under the increasing atmospheric CO(2) levels. Lolium perenne L. was grown hydroponically under two concentrations of atmospheric CO(2) (360 and 1000μLL(-1)) and six conce...

background:   myasthenia  gravis (mg) is an  autoimmune disorder   characterized   by  weakness   and   fatigability  of skeletal muscles. the aim of this study was to determine if pathological characteristics in non-thymomatous patients of mg would correlate with prognosis in a three year follow up. methods:   patients  who  had  had  their  thymectomy   at least  three  years prior to  the  s...

Cadmium is a toxic metal that inactivates DNA-repair proteins via multiple mechanisms, including zinc substitution. In this study, we investigated the effect of Cd(2+) on the Bloom protein (BLM), a DNA-repair helicase carrying a zinc-binding domain (ZBD) and playing a critical role to ensure genomic stability. One characteristics of BLM-deficient cells is the elevated rate of sister chromatid e...

Three molecular sulfido complexes containing a Cd-S-Sn structure motive, [{(tmeda)Cd}3(SnPh)2S6] (1), [{(tmeda)Cd}2(SnPh2)2S4] (2) and [{(iPr3P)Cd}3Cd4(SnPh2)6S13] (3), have been synthesized characterized by single-crystal X-ray diffraction. So far, 2 is the first cadmium tin complex soluble in common organic solvents. Analysis 113Cd 119Sn NMR spectroscopy shows slow rearrangement solution, whi...

Calcium (Ca) and the toxic heavy metal cadmium (Cd) are antagonistic ions competing for uptake in plants when they co-occur in soil solutions, and high Ca concentrations can reduce the uptake of Cd in plants. However, less is known about the effects of low Ca bioavailability on Cd uptake and translocation in plants. We hypothesized that low Ca availability would enhance Cd uptake and translocat...

In the title complex, [Cd(CH(3)COO)(2)(C(4)H(8)N(2)S)(2)], the Cd(II) cation is coordinated by three acetate O atoms and two S atoms of Diaz [Diaz = 1,3-diazinane-2-thione = 3,4,5,6-tetra-hydro-pyrimidine-2(1H)-thione]. The Cd(II) coordination is augmented by one considerably longer Cd-O bond of 2.782 (3) Å to a carboxyl-ate O atom. The resulting coordination polyhedron around the Cd(II) cation...

Cadmium (Cd(2+)) is a toxic heavy metal and a well-known human carcinogen. The toxic effects of Cd(2+) on biological systems are diverse and thought to be exerted through a complex array of mechanisms. Despite the large number of studies aimed to elucidate the toxic mechanisms of action of Cd(2+), few have been targeted toward investigating the ability of Cd(2+) to disrupt multiple cellular pat...

The methodology agreed within the framework of HBM4EU project is used in this work to derive HBM-GVs for general population (HBM-GVGenPop) and workers (HBM-GVWorker) exposed cadmium (Cd) its compounds. For Cd, a significant number epidemiological studies with dose–response relationships are available, particular kidney effects. These effects described terms relation between urinary Cd (U-Cd) or...

Cathepsin D (CD) up-regulation has been associated with human malignancy and poor prognosis. Thrombin up-regulated CD mRNA and protein in eight tumor cell lines as well as in human umbilical vascular endothelial cells (HUVEC). Thrombin increased the secretion of CD by 3- to 8-fold and enhanced chemotaxis ( approximately 2-fold) in 4T1 murine mammary CA cells, which was completely inhibited with...

Cadmium (Cd) is an extremely toxic metal, capable of severely damaging several organs, including the brain. Studies have shown that Cd disrupts intracellular free calcium ([Ca(2+)]i) homeostasis, leading to apoptosis in a variety of cells including primary murine neurons. Calcium is a ubiquitous intracellular ion which acts as a signaling mediator in numerous cellular processes including cell p...
