Mechanisms of enhanced sulfur tolerance on samarium (Sm)-doped cerium oxide (CeO2) from first principles.
The role of samarium (Sm) 4f states and Sm-perturbed O 2p states in determining the sulfur tolerance of Sm-doped CeO2 was elucidated by using the density functional theory (DFT) + U calculation. We find that the sulfur tolerance of Sm-doped CeO2 is closely related to the modification of O 2p states by the strong interaction between Sm 4f and O 2p states. In particular, the availability of unocc...
متن کاملMyelotoxicity of samarium Sm 153 lexidronam in patients receiving prior treatment with chemotherapy or radiotherapy.
BACKGROUND The effect of prior treatment with radiotherapy and/or chemotherapy on the myelotoxicity of samarium lexidronam (Sm 153) in patients with metastatic bone lesions and bone pain was described. METHODS Single-institution retrospective chart review of patients receiving Sm 153. The effect of Sm 153 on peripheral white blood cell (WBC), platelet counts, and change from baseline was calc...
متن کاملRegulation of Alr1 Mg Transporter Activity by Intracellular Magnesium
Mg homeostasis is critical to eukaryotic cells, but the contribution of Mg transporter activity to homeostasis is not fully understood. In yeast, Mg uptake is primarily mediated by the Alr1 transporter, which also allows low affinity uptake of other divalent cations such as Ni(2+), Mn(2+), Zn(2+) and Co(2+). Using Ni(2+) uptake to assay Alr1 activity, we observed approximately nine-fold more ac...
متن کاملThe effect of potassium and magnesium infusion on plasma Mg concentration and Mg balance in ewes.
1. Concentrations of magnesium in plasma, the ionic concentration in rumen digesta supernatant fractions, Mg balance and electropotential differences were measured in three ewes which were fed on grass and supplemented with potassium and Mg by intraruminal infusion. 2. Mean plasma Mg concentrations were unaltered by combined K and Mg treatments, but fell (P less than 0.001) when K alone was inf...
متن کاملReduction of magnesium orthovanadate Mg ( VO ) 3 4 2
Reduction of polycrystalline and crystalline magnesium orthovanadate Mg V O by hydrogen was investigated in the temperature 3 2 8 range of 560–9208C. A single crystal of orthorhombic Mg V O with a cation-deficient-spinel structure (25% of the magnesium atoms on 3 2 8 octahedral sites are vacant) was transformed into cubic Mg V O which has a cation-stuffed-spinel structure (8a and 16c sites were...
