Fiber catalysts are easy to handle and free of mass-transfer resistance. This report is the first application of cloth catalysts to water denitrification. In this work, cloths woven from glass fibers (GF) of 7–10 mm in diameter, impregnated with Pd, were t ...
We have isolated a novel protein kinase cDNA, PfPK6, by differential display RT-PCR (DDRT-PCR) of mRNA obtained from different asexual erythrocytic stages of Plasmodium falciparum, which shows sequence similarity to both cyclin-dependent kinase (CDK) and m ...
NK cell function is negatively regulated by MHC class I-specific inhibitory receptors. Transduction of the inhibitory signal involves protein tyrosine phosphatases such as SHP-1 (SH2-containing protein tyrosine phosphatase-1). To investigate the role of SH ...
The water-soluble tertiary phosphine complex of ruthenium(II), [RuCl2(PTA)(4)], (PTA. 1,3,5-triaza-7-phosphaadamantane) was used as catalyst precursor for hydrogenation of CO2 and bicarbonate in aqueous solution, in the absence of amine or other additives, ...
Isocitrate lyase (ICL) plays a pivotal role in the persistence of Mycobacterium tuberculosis in mice by sustaining intracellular infection in inflammatory macrophages. The enzyme allows net carbon gain by diverting acetyl-CoA from beta-oxidation of fatty a ...
The catalytic properties of Pd and Pt supported on woven glass fabrics were explored for liq.-phase hydrogenation of benzaldehyde as a model for three-phase catalytic reaction. The catalysts demonstrated high activity and are suitable materials to be used ...
The concept of nonfaradaic electrochem. modification of catalytic activity (NEMCA) was applied for the in situ control of catalytic activity of a rhodium film deposited on YSZ (yttria stabilized zirconia) solid electrolyte towards redn. of 1000 ppm NO by 1 ...
Interaction of V2O5 with TiO2 during prepn. of V/Ti-oxide catalysts via solid-state reaction was studied using in situ FT-Raman spectroscopy, HRTEM and XPS. This interaction results in the formation of monomeric vanadia species with vanadium in tetrahedral ...
Lon (or La) is a soluble, homooligomeric ATP-dependent protease. Mass determination and cryoelectron microscopy of pure mitochondrial Lon from Saccharomyces cerevisiae identify Lon as a flexible ring-shaped heptamer. In the presence of ATP or 5'-adenylylim ...
Proceedings of the National Academy of Sciences1999
The intramolecular cyclisation of 2-hydroxyphenylacetic acid 1 into coumaran-2-one 2 was studied under both microwave irradiation and classical heating for comparison purposes. The use of a monomode oven allowed an accurate consideration of the temperature ...
