Surface modification of 600-µm-sized monodisperse gamma-alumina microspheres into magnesium–aluminum spinel, and co-impregnation-based loading Rh–Ni (0.46 wt% Rh, 9.03 Ni) were performed to synthesize catalysts for diesel-steam-reforming hydrogen. The intimate interactions between Rh Ni, the formation alloy, Rh-doping-induced decrease in particle size Ni determined. DFT calculations results rev...

A dinuclear Rh(− i )/Rh( ) complex bridged by tridentate phosphinine ligands was prepared reduction of the corresponding Rh( complex. An unsymmetric bridging mode differentiated electronic environments Rh centres.

Recombinant human-interferon-gamma (rH-IFN-gamma) and verapamil (VRP), either alone or in combination, were evaluated in MTT assay for their modification effects on adriamycin-induced cytotoxicity against MKN-45, human stomach adenocarcinoma cells. VRP as a single agent did not inhibit the survival of MKN-45 at doses of up to 5.0 micrograms/ml. The survival of MKN-45 was inhibited by rH-IFN-gam...

We have investigated the adsorption and decomposition of ethanol on the Rh(111) and Rh(553) surfaces at room temperature with special emphasis on the dehydrogenation. We use high resolution core level photoemission and density functional theory (DFT) based simulations. A detailed analysis of the C1s core level spectra, including analysis of the vibrational fine-structure and comparison to calcu...

AIM To determine the overall and comparative incidence of refeeding hypophosphatemia (RH) between enteral and parenteral nutrition in general adult intensive care unit (ICU) patients. MATERIALS AND METHODS This study was performed as a retrospective analysis. A total of 117 patients who received enteral and parenteral nutrition were included in the study. Demographic characteristics, type of ...

We studied changes in the pharmacokinetics of 125I-recombinant human erythropoietin (125I-rh-EPO) after repeated subcutaneous administration once a week for 4 weeks. The plasma level of trichloroacetic acid-precipitable radioactivity after the fourth administration of 125I-rh-EPO was minimal in 8 of 10 rats, whereas in the other two rats, the plasma level was almost the same or somewhat higher ...

This study examined the thermoregulatory and circulatory responses, and exercise performance of trained distance runners during exercise in the heat (31°C) at varying relative humidity (RH). In a randomized order, 11 trained male distance runners performed 5 60 min steady-state runs at a speed eliciting 70% of VO2max in RH of 23, 43, 52, 61 and 71%. This was followed immediately with an increme...

OBJECTIVE The purpose of this study was to determine the most cost-effective option to prevent alloimmunization against the Rh factor. METHODS A virtual population of Rh-negative pregnant women in Quebec was built to simulate the cost-effectiveness of preventing alloimmunization. The model considered four options: (1) systematic use of anti-D immunoglobulin; (2) fetal Rh(D) genotyping; (3) im...

Rh-based catalysts to be used for the synthesis of C -oxygenates from syngas were characterized with EPR, TPR, IR and 2 XPS methods. The chemical state of the Mn component was extensively studied with EPR after in situ reduction and treatment with various probe molecules. The results indicated that on the MnrSiO catalyst, Mn can exist as isolated Mn 2 ions on the surface of SiO through the form...

The effects of ceria and zirconia on the structure-function properties of supported rhodium catalysts (1.6 and 4 wt % Rh/γ-Al2O3) during CO exposure are described. Ceria and zirconia are introduced through two preparation methods: 1) ceria is deposited on γ-Al2O3 from [Ce(acac)3] and rhodium metal is subsequently added, and 2) through the controlled surface modification (CSM) technique, which i...
