(ACADEMIC PRESS AUST, 1996-08)Extracellular nucleotides interact with specific receptors on the cell surface and are locally metabolized by ecto-nucleotidases. Biochemical characterization of the ATPase and ADPase activities detected in rat heart ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1992-06)Two forms of ATP-diphosphohydrolase were identified in Solanum tuberosum tuber var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were over 10 for form A and 1 for form B. In the potato tuber homogenate the ...
-
(ASSOC BRAS DIVULG CIENTIFICA, 1996-05)ATP-diphosphohydrolase (apyrase, EC 3.6.1.5) has both ATPase and ADPase activity that are stimulated by bivalent metals, with Ca2+ being the most effective. The possible physiological function of this enzyme, associated ...
-
(Royal Society of Chemistry, 1987)In pyridine - formic acid buffer and tetramethylammonium chloride solution over the pH range 0-8.5, nitrofurazone, furazolidone and other nitrofuran derivatives are reduced in a six-electron process, giving rise to a well ...

(PERGAMON-ELSEVIER SCIENCE LTD, 2002-01-15)The electrochemical reduction of copper(II) complexes with salen Schiff-base ligands derived from ethylenediamine or (R,R) or (S,S)-1,2-diphenylethylenediamine and 5-methoxy, 5-bromo and 5-nitrosalicylaldehyde have been ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-10-01)The two 1,10-phenanthroline ligands in the mixed Delta-cobalt(III) complex with sucrose are in different environments relative to the sucrose ligand as shown by differences in their H-1 NMR signals and predicted by structural ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004-03-15)Although it is well established that both follicular assembly and the initiation of follicle growth in the mammalian ovary occur independently of pituitary hormone support, the factors controlling these processes remain ...
-
(AOAC INTERNATIONAL, 2001-09)The aim of the work described in this paper was to provide a fast, easy, inexpensive, precise, and accurate method for the determination of melatonine in solid pharmaceutical dosage forms. The developed method is based on ...
-
(Bentham Science Publishers, 2003)The present review discusses the synthetic strategies of new ligands exhibiting mainly 5-HT1A binding affinities. Specifically we focused our attention in the synthesis of compounds structurally related to arylpiperazine, ...
-
(CAMBRIDGE UNIV PRESS, 2002-10-01)The hypothesis that nitric oxide plays a key role in the regulation of adrenal blood flow and plasma concentrations of cortisol and catecholamines under basal and hypoxaemic conditions in the llama fetus was tested. At ...
-
(OXFORD UNIV PRESS, 2002-10)BACKGROUND: The aim of this study was to evaluate the peripheral serum androgen concentrations in normal and polycystic ovarian syndrome (PCOS) women during pregnancy, in order to establish if PCOS may induce gestational ...
-
(ENDOCRINE SOC, 2003-10-01)Administration of estradiol valerate (EV) to adult rats leads to anovulation and cystic ovarian morphology. Sympathetic ovarian nerve denervation (SONX) overcomes this disruption. In this study, we determined whether EV ...
-
(AMER SOC MICROBIOLOGY, 1996-07)Lignin peroxidase-like genes were PCR amplified from Phanerochaete sordida and Ceriporiopsis subvermispora, fungi lacking lignin peroxidase (LiP) activity. Amplification products were highly similar to previously described ...
-
(ELSEVIER SCIENCE INC, 2002-04-16)The white rot basidiomycete Ceriporiopsis subvermispora secretes the ligninolytic enzymes manganese-dependent peroxidase (MnP) and laccase to the extracellular medium. The promoter region of the laccase gene (Cs-lcsl) ...
-
(ELSEVIER SCIENCE BV, 2002-05-09)Eighty-two amino acid sequences of the catalytic domains of mature endoxylanases belonging to family 11 have been aligned using the programs MATCHBOX and CLUSTAL. The sequences range in length from 175 to 233 residues. The ...
