The electronic and optical natures of silica-coated semiconductor nanocrystals (Cd(2)Te(2)@(SiO(2))(24)) have been investigated by density functional theory (DFT) and time-dependent DFT calculations. The calculated results of Cd(2)Te(2)@(SiO(2))(24) have revealed that the structural synergy effect between the Cd(2)Te(2) quantum dots (QDs) and the silica coating shell plays a dominant role in th...

UNLABELLED Lumen-to-cell transport, cellular accumulation, and toxicity of cadmium as ionic cadmium (Cd(2+)) or as the L-cysteine (Cys) or D,L-homocysteine (Hcy) S-conjugate of cadmium (Cys-S-Cd-S-Cys, Hcy-S-Cd-S-Hcy) were studied in isolated, perfused rabbit proximal tubular segments. When Cd(2+) (0.73 microM) or Cys-S-Cd-S-Cys (0.73 microM) was perfused through the lumen of S(2) segments of t...

The chemokine domain of fractalkine (FKN-CD) binds to the classical RGD-binding site of αvβ3 and that the resulting ternary complex formation (integrin-FKN-CX3CR1) is critical for CX3CR1 signaling and FKN-induced integrin activation. However, only certain cell types express CX3CR1. Here we studied if FKN-CD can activate integrins in the absence of CX3CR1. We describe that WT FKN-CD activated re...

In the present study, Cd(2+) adsorption on polyacrylate-coated TiO(2) engineered nanoparticles (TiO(2)-ENs) and its effect on the bioavailability as well as toxicity of Cd(2+) to a green alga Chlamydomonas reinhardtii were investigated. TiO(2)-ENs could be well dispersed in the experimental medium and their pH(pzc) is approximately 2. There was a quick adsorption of Cd(2+) on TiO(2)-ENs and a s...

The two dinuclear Cd(II) complexes [Cd(BPMST)(SCN)]2 (1) and [Cd(BPMST)(N3)Cl]2 (2) of a s-triazine/pyrazolo ligand (BPMST) were synthesized. preparation both was performed in water–ethanol solvent mixture involved the mixing functional BPMST with CdCl2 presence thiocyanate or azide as linkers, respectively. formula involvement pesudohalide linker between centers approved by single crystal X-ra...

A subset of human CD4 2 CD8 2 T cells that expresses an invariant V a 24-J a Q T cell receptor (TCR)a chain, paired predominantly with V b 11, has been identified. A series of these V a 24 V b 11 clones were shown to have TCRb CDR3 diversity and express the natural killer (NK) locus–encoded C-type lectins NKR-P1A, CD94, and CD69. However, in contrast to NK cells, they did not express killer inh...

BACKGROUND/AIMS The present study was conducted to investigate the renal tubular handling of inorganic cadmium (Cd(2+)) by exposing primary human tubular cell cultures to physiologically relevant doses of cadmium chloride (CdCl(2)). Furthermore, the cellular accumulation of Cd(2+) was compared to that of metallothionein-1-bound Cd (Cd7MT-1). Finally, this study aimed to investigate the effect o...

In this study chitosan hydrogel beads with porosity ~ 0.86 and diameter ~ 20.07 mm were prepared from 85 % deacetylated chitosan for removal of Cd2+ ions from aqueous solutions.  Chitosan powder was dissolved into dilute acetic acid as solvent and formed into spherical beads using a phase inversion technique. The effect of temperature, initial ...

Supply of cadmium chloride (0.5 mM) inhibited chlorophyll formation in greening maize leaf segments, while lower concentration of Cd (0.01 mM) slightly enhanced it. Inclusion of 2-oxoglutarate (2-OG, 0.1-10 mM) in the incubation mixture increased chlorophyll content in the absence as well as presence of Cd. Substantial inhibition of chlorophyll formation by Cd was observed at longer treatment b...
