(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 ...
-
(NEW YORK ACAD SCIENCES, 1996)The adrenoleukodystrophy protein (ALDP) and the 70-kDa peroxisomal membrane protein (PMP70) are half ATP binding cassette (ABC) transporters in the peroxisome membrane. ALDP is defective in X-linked adrenoleukodystrophy ...
-
(KLUWER ACADEMIC PUBL, 1997-05)Copper mining activities are very important in central Chile. Like other metals, copper is a nutrient for most plants at low concentration levels; however, at higher levels it may become toxic. At present, copper abundance ...
-
(AMER CHEMICAL SOC, 1996-05-15)The roles of chemical kinetics and mass transfer in two types of bioreactors (packed-column reactors and rotating disk bioreactors), used with continuous-now sample/reagent(s) processing, are discussed in detail. A normalized ...
-
(ROYAL SOC CHEMISTRY, 1997-10)A flow injection photometric method for the sequential determination of zinc and copper in mixtures was developed based on the variation of the stability of the chromogenic complexes between the analytes and the reagent ...
-
(INST ORGANIC CHEM AND BIOCHEM, ACAD SCI CZECH REPUBLIC, 1991-12)Five N-p-phenyl substituted benzamidines were studied by DC and DP polarography in a wide pH range. Coulometric results show that the overall processes are four-electron reductions. Logarithmic analysis of the waves indicate ...
-
(AMER PHARMACEUTICAL ASSN, 1990)Nifurtimox is polarographically reducible over the whole pH range, the nitro group being reduced to the hydroxylamine group in a 4ē process and subsequently the amine being formed in a 2ē process at a pH value below 4. The ...
