(Socidrogalcohol. Sociedad Científica Española de Estudio sobre el Alcohol, el Alcoholismo y las otras Toxocomanías, 2020)Tras consumir etanol, el disulfiram incrementa los niveles de acetaldehído en sangre y genera una reacción aversiva que desalienta el consumo de alcohol. Dados los importantes efectos secundarios del disulfiram, es ...

(Elsevier, 2017)The synthesis of unsymmetrical ferrocenyl and cyrhetrenyl azines [(h5-C5H4)-CR¼N-N¼CH-2-C4H2X-5-NO2]M (M¼Re(CO)3, Fe(h5-C5H5); R¼H, CH3,X¼O, S) has led to the development of new derivativesof 5-nitroheterocycles as potential ...
-
(WILEY-V C H VERLAG GMBH, 2004-11-04)Ferroelectricity can be defected in systems consisting of liquid-crystal line monomer-polymer mixtures possessing no chiral centers The ferroelectric behavior in mixtures of achiral liquid-crystalline side-chain polymers ...
-
(Elsevier, 2014)The goal of this investigation was to develop films containing insulin-coated nanoparticles and evaluate their performance in vitro as potential peptide delivery systems. To incorporate insulin into the films, a new ...
-
(FEDERATION AMER SOC EXP BIOL., 2005-05)One of the hallmarks of Alzheimer's disease is the self-aggregation of the amyloid beta peptide (A beta) in extracellular amyloid fibrils. Among the different forms of A beta, the 42-residue fragment (A beta(1-42)) readily ...
-
(2002)We discuss a nonhomogeneous population of pulsatil integrate-and-fire neural oscillators, coupled through purely inhibitory synapses. For instantaneous communication, we provide a strategy to generate synaptic couplings ...
-
(Royal Society of Chemistry, 2015)M′0.2Mn 0.8PS3·0.25H2O materials are obtained by a mild microwave assisted reaction (M′ = CoII, NiII, CuII, ZnII), which permitted us to obtain the first copper(ii) bimetallic phase. All these materials have a lower energy ...
-
(American Chemical Society, 2015)The first borate-vacant deca-vanadoborate of formula (NH3CH2CH2CH2NH3)(5) [ (NH3CH2CH2CH2NH3)V10B24O66H8]center dot 13.23H(2)O with an occluded 1;3-propanediammonium cation; using molten methylboronic acid flux reaction ...
-
(Sociedad de Biología de Chile, 2014)Background: Loxoscelism is the envenomation caused by the bite of Loxosceles spp. spiders. It entails severe necrotizing skin lesions, sometimes accompanied by systemic reactions and even death. There are no diagnostic means ...
-
(2008)A series of five compounds containing the bicyclo-[3.3.0]octa-2,6-diene skeleton are described, namely tetra-methyl cis,cis-3,7-dihydroxy-bicyclo-[3.3. 0]octa-2,6-diene-2,4-exo,6,8-exo-tetracarboxyl-ate, C16H18O10, (I), ...

(Public Library Science, 2015)In this work, the relationship between the molecular structure of three flavonoids (kaempferol, quercetin and morin), their relative location in microheterogeneous media (liposomes and erythrocyte membranes) and their ...
-
(Bentham Science Publishers B.V., 2014)In this article we review the flow chemistry methodologies for the controlled synthesis of different kind of nano and microparticles for biomedical applications. Injection mechanism has emerged as new alternative for the ...
-
(MARCEL DEKKER INC, 1999)A simple flow injection photometric method for the determination of copper was developed based on the formation and liquid-liquid extraction of the analyte-bathocuproine-perchlorate ternary complex. The analytical reaction ...
-
(WILEY-V C H VERLAG GMBH, 2000-03)The analytical application of a simple polarographic Row through cell, which was previously designed for the continuous polarographic analysis of organic compounds in pharmaceuticals and urine, is proposed in this work for ...
-
(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 ...
-
(ACADEMIC PRESS INC JNL-COMP SUBSCRIPTIONS, 1996-05)An integrated retention/photometric detection method for the determination of microamounts of iron was developed. The method is based on the retention of the reaction product of the analyte with ferrozine in a flow cell ...
