(BioMed Central Ltd., 2004-06-04)Arabidopsis thaliana copper metallochaperone CCH is a functional homologue of yeast antioxidant ATXI, involved in cytosolic copper transport. In higher plants, CCH has to be transported to specialised cells through ...
-
(AMERICAN PHYSICAL SOC, 2000-01)Thin freely suspended films of a mixture of an achiral side-chain liquid crystal polymer and its monomer have been studied with depolarized reflected light microscopy. We observe that regions with an odd number of bilayers ...
-
(ELSEVIER SCIENCE BV, 2004-03)The appropriate experimental conditions of Mo(VI) ion transport across a supported liquid membrane containing Alamine 336 as the mobile carrier dissolved in kerosene solvent have been investigated. The molybdenum flux has ...
-
(AMER SOC PHOTOBIOLOGY, 2005-03)Thyronine derivatives are essential indicators of thyroid gland diseases in clinical diagnosis and are currently used as standards for developing ordinary biochemical assays. Photooxidation of gland hormones of the thyronine ...
-
(ACADEMIC PRESS INC, 2001-05-25)The endogenous dopamine-derived neurotoxin salsolinol was found to decrease survival in the dopaminergic neuronal cell line RCSN-3, derived from adult rat substantia nigra in a concentration-dependent manner (208 muM ...
-
(WILEY-V C H VERLAG GMBH, 1999-11)A flavoenzyme cytochrome c reductase NAD(P)H mixture has been used to modify a carbon paste electrode. The modified electrode was characterized by cyclic voltammetry varying the scan rate and temperature. Cathodic and ...
-
(ROYAL SOC CHEMISTRY, 1990-04)The electrochemical reduction of 7-nitro-1,4-benzodiazepin-2-ones and of their acid hydrolylis products, 2-amino-5-nitrobenzophenones, was studies by polarography and cyclic voltammetry in a solvent - buffer system containing ...
-
(Pergamon Press Ltd, 1982)During 1 yr, CO2-C losses from 7 agricultural soils containing 0,5-1,5% organic C ranged from 70 to 243 mg 100g-1 while losses from three allophanic soils containing 4,9-8,9% organic C varied from 92 to 191 mg. Losses as ...
-
(Sociedad Chilena de Química, 2002)Un nuevo compuesto polipiridilcarbonilo bimetálico de renio(I) y rutenio(II) y los correspondientes complejos precursores monometálicos fueron preparados. Los compuestos fueron caracterizados física y espectroscópicamente ...
-
(Marcel Dekker, Inc., 1998)Methods for the regioselective bromination of the title naphthalenone are described, wich lead to isomeric hydroquinones 5 or 6..
-
(ELSEVIER SCI IRELAND LTD, 2003-09-18)The effect of perinatal asphyxia on brain development was studied with organotypic cultures from substantia nigra, neostriatum and neocortex. Asphyxia was induced by immersing foetuses-containing uterine horns removed from ...

(MUNKSGAARD INT PUBL LTD, 1993-09-15)The crystal consists of discrete dimeric units, di-mu-chloro-bis[chloro(4,4'-dimethyl-2,2'-bipyridine)copper(II)] hydrate, linked to one water molecule and to another unit by van der Waals forces. Each dimeric unit contains ...
-
(Sociedad Chilena de Química, 1989)Se estudió la reacción de condensación de di-2-piridilmatano con los compuestos carbonílicos: benzaldehido, 2, piridilcarboxaldehido, acetona y di-2-piridilcetona, catalizada por sales de los metales de la primera serie ...
-
(ELSEVIER SCIENCE BV, 1998-01-30)IGF-1 increased 2-fold protein synthesis in cardiac myocytes. Genistein, whether added during preincubation or with IGF-I at the start of incubation, significantly inhibited the IGF-1-induced stimulation of protein synthesis, ...
-
(ELSEVIER SCIENCE BV, 1998-11-20)Basic fibroblast growth factor (bFGF) stimulated [H-3]thymidine incorporation at all stages of development, although the magnitude of this effect was the greatest in cells derived from pregnant mice. Cells primed with ...
-
(ELSEVIER SCIENCE SA, 2001-12-31)Detection of O-2((1)Delta(g)) phosphorescence emission, lambda(max) = 1270 nm, following laser excitation and steady state methods were employed to determine the total rate constant, k(T), for the reaction between the ...
-
(AMER SOC PHOTOBIOLOGY, 1996-06)An equation is proposed for the evaluation of partition or association constants from fluorescence properties (such as spectrum shape or anisotropy) whose values are not linearly related to the solute distribution. The ...
