Background: The regular intake of probiotics is alleged to help prevent or shorten the duration of common colds and gastrointestinal diseases. Previous clinical trials have shown protective effects in young children, while effects in adults have not yet been sufficiently investigated. Methods: This study examines the effect of the regular intake of the probiotic Lactobacillus reuteri (DSM 17938...
Um método simples de eletroforese capilar de zona (CZE) foi desenvolvido e validado para análise de carbonato de lodenafila em comprimidos. A metodologia de superfície de resposta foi utilizada para a otimização do pH, concentração do tampão, voltagem e temperatura. O método utilizou como eletrólito, tampão borato 50 mmol L, pH 10, voltagem de 15 kV. A separação foi efetuada em capilar de sílic...
We have synthesized inorganic micron-sized filaments, whose microstucture consists of silica-coated nanometer-sized carbonate crystals, arranged with strong orientational order. They exhibit noncrystallographic, curved, helical morphologies, reminiscent of biological forms. The filaments are similar to supposed cyanobacterial microfossils from the Precambrian Warrawoona chert formation in Weste...
In the title solvated mol-ecular salt, 2C4H12N5 (+)·CO3 (2-)·2CH3OH, the complete carbonate ion is generated by crystallographic twofold symmetry, with the C atom and one O atom lying on the rotation axis. The cation is twisted about the central C-N bond [C-N-C-N = -137.7 (6)°]. In the crystal, the components are linked by N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds, generating a three-dimensional su...
Using cryogenic helium buffer-gas cooling, we have prepared dense samples of atomic lithium and molecular calcium monohydride at temperatures as low as 1 K. We have measured the Li+CaH→LiH+Ca chemical reaction, observed in both the accelerated disappearance of CaH in the presence of high densities of lithium and in the appearance of the LiH molecule.
Introduction There are three major oil sand areas in Canada, all in Alberta. There is also an oil sand deposit on Melville Island in the Arctic. The three major oil sand areas are from highest to lowest volume of reserves-in-place (AEUB 2003) Athabasca, Cold Lake and Peace River oil sand areas notwithstanding that bitumen reserves are also evident in subcropping carbonate rocks in Athabasca and...
The Cosmetic Ingredient Review (CIR) Expert Panel (Panel) reviewed the safety of 6 simple carbonate salts which function as absorbents, bulking agents, opacifying agents, pH adjusters, buffering agents, abrasives, and oral care agents in cosmetic products. The Panel reviewed relevant data relating to the safety of these ingredients, and concluded that the simple carbonate salts are safe in the ...
We have studied spatial Ca2+ distribution in hair cells filled with the low affinity fluorescent indicator Calcium Green 5N using real-time confocal microscopy and whole-cell recording. During depolarizations lasting several hundred milliseconds, Ca2+ fluorescence increased at a number of hotspots around the base of the cell but changed little near the hair bundle. The hotspots required influx ...
In previous reports, flowing CO2 at the cathode is essential for either conventional molten carbonate fuel cells (MCFCs) based on molten carbonate/LiAlO2 electrolytes or matrix-free MCFCs. For the first time, we demonstrate a high-performance matrix-free MCFC without CO2 recirculation. At 800°C, power densities of 430 and 410 mW/cm(2) are achieved when biomass-bamboo charcoal and wood, respecti...
