The asymmetric unit of the title compound, [Cd(NCS)(2)(C(9)H(13)N)(4)], consists of one Cd(II) cation located on a centre of inversion, one thio-cyanate anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.25:0.75 ratio and was refined using a split ...

The effects of CdSO(4) additions on the gene expressions of a mercury reductase, merA, an oxidative stress protein, trxA, the ammonia-monooxygenase enzyme (AMO), amoA, and the hydroxylamine oxidoreductase enzyme (HAO), hao, were examined in continuously cultured N. europaea cells. The reactor was fed 50 mM NH(4)+ and was operated for 78 days with a 6.9 days hydraulic retention time. Over this p...

Cadmium (Cd) toxicity and production of different thiols (phytochelatins, glutathione, gamma-Glu-Cys and cysteine) were studied in the microalga Chlamydomonas moewusii exposed to different concentrations of this metal (1, 2, 4, 6, 8, and 10 mg/L) for 96 h. The inhibitory effect of Cd on growth was demonstrated. The value of EC50 (metal concentration which reduces the population growth to 50% of...

In the title coordination polymer, [Cd(C(7)H(4)N(3)O(2))(2)(C(3)H(7)NO)(2)](n), the Cd(II) atom, lying on an inversion center, is six-coordinated in a distorted N(4)O(2) octa-hedral geometry. The N atoms of the 4-nitrophenylcyanamide anions form the equatorial plane and the O atoms of the dimethyl-formamide mol-ecules occupy the axial positions. The anions act as bridging ligands, connecting th...

the isolated perfused rat liver (iprl) model has been used into toxicology study of rat liver. this model provides an opportunity at evaluation of liver function in an isolated setting. studies showed that cd, in a dose-dependent manner, induced toxic effects in iprl models, and these effects were associated with aminotransferase activity and lipid peroxidation. the aim of this study was to inv...

In the title compound, [Cd(ClO(4))(2)(C(15)H(18)N(4))(4)], the Cd(II) ion is coordinated in a slightly distorted octa-hedral environment by two trans monodentate perchlorate ligands and four 1-(2-pyrid-yl)-4-(4-pyridylmeth-yl)piperazine (pmpp) ligands. In the crystal structure, mol-ecules are organized into layers parallel to the ab plane by C-H⋯O inter-actions. Similar inter-actions promote th...

BACKGROUND Human T-cell lymphotropic virus type I (HTLV-I) is a retrovirus that influences cellular metabolism modifying biological responses. This results in oncogenic, degenerative or inflammatory changes. The myelopathy associated to HTLV-I or tropical spastic paraparesia (HAM/TSP) is a mainly degenerative response to the virus infection. On the other hand, Sjögren syndrome has an inflammato...

The present study investigates the effect of progesterone, a pregnane precursor of neurosteroids, and 4'-chlordiazepam (4'-CD), a specific ligand for mitochondrial diazepam binding inhibitor receptor (MDR) involved in neurosteroidogenesis, on restraint stress (RS)-induced modulation of humoral and cell-mediated immune responses. RS produced a significant reduction in anti-sheep red blood cells ...

BACKGROUND. Morphological patterns of Paneth cells are a prognostic biomarker in Western Crohn's disease (CD) patients, and are associated with autophagy-associated ATG16L1 and NOD2 variants. We hypothesized that genetic determinants of Paneth cell phenotype in other ethnic CD cohorts are distinct but also involved in autophagy. METHODS. We performed a hypothesis-driven analysis of 56 single nu...
