This work reported the radiation shielding characteristic of bismuth titanium vanadium sodium tellurite glass system. The density specially-developed samples was increased from 2.21 to 4.01 g/cm3 with addition Bi2O3, despite fact molar volume is decease within 85.43–54.79 cm3/mol. WinXcom program used approximate effect Bi2O3 on gamma parameters glasses. μm values decrease increase concentratio...

Structural, thermal and optical properties of lead-tellurite oxide glasses consisting TeO2 – PbO Bi2O3 Er2O3, synthesized by high temperature melt-quenching-thermal annealing method were investigated in this study. The role rare-earth element, erbium ion as dopant into the host glass has affected physically, thermally optically glasses. amorphous nature was confirmed XRD (x-ray diffraction). Th...

22 23 The tellurium oxyanion tellurite is toxic to most organisms because of its 24 ability to generate oxidative stress. However, the detailed mechanism(s) how this 25 toxicant interferes with cellular processes have yet to be fully understood. As part 26 of our effort to decipher the molecular interactions of tellurite with living systems, 27 we have evaluated the global metabolism of α-ketog...

Lactobacillus reuteri inhibits Staphylococcus aureus growth on Baird-Parker agar. This activity required the presence of tellurite and was not shared with other lactic acid bacteria or an L. reuteri mutant defective in cystine metabolism. Secreted products generated from L. reuteri cystine metabolism and thiols were shown to augment tellurite toxicity.

The highly toxic oxyanion tellurite has to enter the cytoplasm of microbial cells in order to fully express its toxicity. Here we show that in the phototroph Rhodobacter capsulatus, tellurite exploits acetate permease (ActP) to get into the cytoplasm and that the levels of resistance and uptake are linked.

Culture on cefixime, tellurite, and sorbitol-MacConkey agar after HCl treatment facilitated the growth of 410 (94%) of 436 eae-positive Shiga toxin-producing Escherichia coli (STEC) strains and 17 (16%) of 107 eae-negative STEC strains. This selectivity was closely related to acid resistance in E. coli and tellurite resistance in eae-positive STEC strains.
