Catalytic conversion of cellulose to ethylene glycol over a low-cost binary catalyst of Raney Ni and tungstic acid.
ChemSusChem 6(4) , 652-8, (2013) Following our previous report on the selective transformation of cellulose to ethylene glycol (EG) over a binary catalyst composed of tungstic acid and Ru/C, we herein report a new low-cost but more effective binary catalyst by using Raney nickel in place of ... |

Identification in various chlorate-resistant mutants of a protein involved in the activation of nitrate reductase in the soluble fraction of a chlA mutant of Escherichia coli K-12.
Biochim. Biophys. Acta 839(2) , 181-90, (1985) We report some properties of Protein PA which has been isolated from the soluble fraction of a chlB mutant after anaerobic growth in the presence of KNO3. This protein has been identified by its capacity to reactivate nitrate reductase present in the soluble ... |

Effect of oxyanions of the early transition metals on rabbit skeletal muscle phosphorylase.
Biochemistry 22(21) , 4994-5000, (1983) The differential effects of the oxyanions of the early transition metals ions V(V), W(VI), and Mo(VI) on the catalytic activity and coenzyme binding of rabbit skeletal muscle phosphorylase are studied. The oligoanions of V(V), W(VI), and Mo(VI) are potent inh... |

Interaction between isopoly-tungstic acid and berberine hydrochloride by resonance Rayleigh scattering spectrum.
Anal. Sci. 19(7) , 1055-60, (2003) In a weak acid medium, when an isopoly-tungstic acid reacts with berberine to form an ion-association complex, strong resonance Rayleigh scattering (RRS) appears and obvious frequency-doubling scattering (FDS) as well as second-order scattering (SOS) come int... |

Vanadate, tungstate and molybdate activate rod outer segment phosphodiesterase in the dark.
Biochim. Biophys. Acta 845(1) , 81-5, (1985) Anionic activation of rod outer segment phosphodiesterase by vanadate, molybdate and tungstate is demonstrated. Comparisons are made to adenylate cyclase, which is known to be activated by vanadate and molybdate but not by tungstate. In view of the difference... |

Spectroscopic and DFT study of tungstic acid peroxocomplexes.
J. Phys. Chem. A 111(11) , 2166-71, (2007) The catalytic system formed by tungstic acid and its complexes with H2O2 and phenylphosphonic acid has been analyzed from the experimental and theoretical points of view. Previous structural studies by XRD proved the validity of the DFT proposed models and me... |

Physicochemical characterization and transformation of the cytosolic glucocorticoid receptor from rabbit liver.
J. Steroid Biochem. 18(6) , 789-99, (1983) Characterization of the glucocorticoid receptor from rabbit liver cytosol was studied in vitro. Binding of [3H]-dexamethasone showed a high affinity (KD = 2.4 . 10(-9)M) and a concentration of binding sites of 0.3 . 10(-12) mol/mg proteins. Association and di... |

Chemical behavior of tungstate solutions. Part 1. A spectroscopic survey of the species involved.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 61(4) , 551-7, (2005) This study is focused on the composition and the evolution of tungstate ions solutions as a function of pH and increasing concentrations. The Raman analysis showed that, during the titration of the tungstate solutions, WO4(2-), HWO4- ions and probably W2O7(2-... |

Analysis of ethchlorvynol (Placidyl): evaluation of a comparison performed in a clinical laboratory.
J. Anal. Toxicol. 8(6) , 263-8, (1984) Common techniques for analyzing ethchlorvynol (Placidyl) by colorimetry and gas liquid chromatography are evaluated. Matrix effects are thoroughly examined to determine their contribution to the validity of results. |
