2,604 Possible Causes for catalytic

  • Seaweed

    Among the noble metals, platinum nanoparticles (PtNPs) are of great importance owing to their catalytic property and less toxicity.[] The significance of this work is a simple one-step synthesis of PtNPs using aqueous extract of Indian brown seaweed Padina gymnospora and their catalytic activity with a polymer[] The present study shows that the catalytic behavior of PtNPs as polymer/metal nanocomposite (PVP/PtNPs) preparation for an antibacterial activity against seven disease causing[]

  • Ewing's Sarcoma

    Furthermore, the catalytic activity of caspase-8 is both necessary and sufficient to confer this sensitivity.[]

  • Infantile Neuroaxonal Dystrophy

    Mutations associated with different disease phenotypes have different effects on catalytic activity.[] Catalytic function of PLA2G6 is impaired by mutations associated with infantile neuroaxonal dystrophy but not dystonia-parkinsonism.[] METHODOLOGY/PRINCIPAL FINDINGS: We produced purified recombinant wildtype (WT) and mutant human PLA2G6 proteins and examined their catalytic function using in vitro assays[]

  • Andrographis

    Abstract We investigated the effects of Andrographis paniculata (AP) extracts and andrographolide on the catalytic activity of three human cDNA-expressed cytochrome P450 enzymes[]

  • Ketoprofen

    In this work we show the application of homogeneous metal-based catalytic systems for the synthesis of Ketoprofen (Scheme 1).[] In terms of enantioselective catalytic reactions, asymmetric hydrogenation 15 and epoxidation 16 reactions have been used as key steps.[] The selective carbonylation of 4 was performed using a catalytic system composed of Pd(dba) 2 , PPh 3 and p -toluenesulfonic acid (Eq. 5).[]

  • Lactulose

    Herein, we summarize recent advances on the enzymatic synthesis of lactulose with emphasis on the selectivity of biocatalysts and their catalytic efficiency in free and immobilized[]

  • Rhodiola Rosea

    Previously, we found that the extract of Rhodiola rosea, one of the most widely used Rhodiola species, had an inhibitory effect on the catalytic activity of cytochrome P450[]

  • Factor XI Deficiency

    […] polymorphism (PCR-SSCP) analysis of his factor XI gene revealed a G-- A transition in codon 501 of exon 13, resulting in a substitution of Trp501 (TGG) by a stop codon (TAG) in the catalytic[] Both are heterozygous for single amino acid substitutions in the fXI catalytic domain (Gly400Val and Trp569Ser). Neither mutant is secreted by transfected fibroblasts.[] […] conformational analysis profiles were obtained for exon 13; sequencing of these products allowed the identification of a novel missense mutation (Trp501Cys) situated in the catalytic[]

  • Forsythia

    […] inhibited the generation of thiobarbituric acid-reactive substances (TBARS) in a dose-dependent manner with IC50 values from 8.5 to 18.7 microM, since HDL oxidation mediated by catalytic[] Notably, the observed effect required proteolytic activity by karilysin, since a catalytically inactive mutant of the enzyme did not affect TNF-α secretion.[] Inactive prokarilysin with the mutated catalytic Glu residue (E136A) was processed by active karilysin at the same sites as the active enzymes.[]

  • Fucosidosis

    This enzyme assembles as a hexamer and displays a two-domain fold, composed of a catalytic (beta/alpha)(8)-like domain and a C-terminal beta-sandwich domain.[] Thus, JH lymphoid cells synthesized a reduced amount of alpha-L-fucosidase that was catalytically inefficient and was hypersecreted.[] In summary, the fucosidosis mutation(s) affected the catalytic activity, quantity, and extracellular release of alpha-L-fucosidase as expressed by lymphoid cells.[]
