The present study examined the effect of three methods of preparation on the properties and catalytic performance of Cu-Mn/SiO2 catalysts for the water gas shift reaction (WGSR). Impregnation and coprecipitation and the new approach of thermal decomposition of [Cu(H2O)6][Mn(dipic)2].2H2O/SiO2 inorganic precursor complex were used for the synthesis of the silica-supported copper-manganese mixed ...

Dysregulation of the proteolytic processing of amyloid precursor protein by γ-secretase and the ensuing generation of amyloid-β is associated with the pathogenesis of Alzheimer's disease. Thus, the identification of amyloid precursor protein binding proteins involved in regulating processing of amyloid precursor protein by the γ-secretase complex is essential for understanding the mechanisms un...

Sol-gel processed SnO2 thin-film transistors (TFTs) were fabricated on SiO2/p+ Si substrates. The active channel layer was deposited by the sol-gel spin coating method. Precursor concentration influenced film thickness and surface roughness. As of precursor increased, films thicker smoother. device performance roughness layer. Decreased resulted in a with lower field-effect mobility, larger sub...

The kinetics of synthesis and turnover of animal cell nuclear precursor-mRNA fractions all of which, in the case of avian erythroblast RNA, are shown by specific complementary DNA hybridization to contain globin mRNA sequences, were analyzed by exponential polyacrylamide gel electrophoresis. Three metabolically distinct size-fractions were characterized: (1) nascent precursor-mRNA (apparent mol...

Transit sequences of chloroplast-destined precursor proteins are phosphorylated on a serine or threonine residue. The amino acid motif around the phosphorylation site is related to the phosphopeptide binding motif for 14-3-3 proteins. Plant 14-3-3 proteins interact specifically with wheat germ lysate-synthesized chloroplast precursor proteins and require an intact phosphorylation motif within t...

in this paper, we used tetranuclear copper (ii) schiff base complexes, [cu4 (μ-sal2hn) (μ-n3)2(n3)2] (1) and [cu4 (μ-salophen) (μ1, 1-n3)2(n3)2] (2), as new precursor in solid-state thermal decomposition for the synthesis of cuo nanoparticles. the crystallinity, purity and morphology of the cuo nanoparticles were characterized by fourier transform infrared (ft-ir), x-ray diffraction (xrd) and s...

The yeasts Pichia pastoris and Saccharomyces cerevisiae have similar overall features regarding the secretory expression of insulin. The S. cerevisiae mating factor alpha (alpha-factor) prepro-leader facilitated the secretion of an insulin precursor, but not proinsulin expressed in P. pastoris. Synthetic prepro-leaders developed for the secretory expression of the insulin precursor in S. cerevi...

Limb muscles derive from muscle precursor cells that lie initially in the lateral portion of the somitic dermomyotome and subsequently migrate to their target limb regions, where muscle-specific gene transcription is initiated. Although several molecules that control the generation and delamination of muscle precursor cells have been identified, little is known about the mechanisms that guide m...
