(Universidad Católica de Valparaíso, 1998-08-15)Ceriporiopsis subvermisporais a white-rot basidiomycete that produces several isoenzymes of manganese peroxidase (MnP). A cADN of one of them (MnP13-1) has been isolated and sequenced. The deduced aminoacid sequence ...
-
(Blackwell Publishing Ltd, 2019)(R/S)-Salsolinol is a full agonist of the μ-opioid receptor (μOR) Gi protein pathway via its (S)-enantiomer and is functionally selective as it does not promote β-arrestin recruitment. Compared to (S)-salsolinol, the ...
-
(2004)The effects of electric fields on hydrogen bonding in ammonia-formic acid system, are examined with STO-3G and 6-31 G(d) wavefunctions. This system was used in a previous work to model hydrogen bonding in crystalline amino ...
-
(Elsevier, 2015)The microextraction of diclofenac and mefenamic acid from water samples was performed by using rotating disk sorptive extraction (RDSE) with molecularly imprinted polymer (MIP) as the sorptive phase. The MIP was synthesized ...
-
(Elsevier Inc., 1986)The lignolytic capacity of some natural bacterial isolates eas examined. Strains were selected from samples of decaying wood by growth in a minimal medium containing aromatic compounds with a structural relationship to ...
-
(ROYAL SOC CHEMISTRY, 2003-04)This paper reports a comparative study of the concentration of three important environmental elements that are often found together in mineral deposits and then associated with mining activities: copper, arsenic and antimony. ...
-
(1997)The monoamine oxidase (MAO) inhibitory properties of a series of amphetamine derivatives with different substituents at or around the para position of the aromatic ring were evaluated. In in vitro studies in which a crude ...
-
(Sociedad Chilena de Quimica, 2001)Maleic anhydride - styrène copolymers were synthesized in acetone-toluene solution at 60° C by azo-bisisobutironitrile.The copolymers were characterized by Gel Permeation Chromatography and Differential Scanning Calorimetry.The ...
-
(Hindawi, 2013)Reactive oxygen species (ROS) damage macromolecules and cellular components in nearly all kinds of cells and often generate toxic intracellular byproducts. In this work, aldehyde generation derived from the Escherichia ...
-
(Public Library Science, 2016)Morin (2' A, 3, 4' , 5,7-pentahydroxyflavone) is a flavonoid with several beneficial health effects. However, its poor water solubility and it sensitivity to several environmental factors avoid its use in applications like ...
-
(Springer, 2016)In order to gain insight into the molecular mechanism of the antioxidant properties of Solanum crispum, aqueous extracts of its leaves were assayed on human erythrocytes and molecular models of its membrane. Phenolics and ...
-
(1969)Several iron (II) nitrosyl bis-dithiocarbamates have been studied by the Mössbauer and other spectroscopic methods. The Mössbauer effect has proved to be useful for studying slight changes in chemical bonding due to ...
-
(Cambridge Univ. Press., 2016)Salmonella Enteritidis is the main cause of foodborne salmonellosis worldwide. The limited effectiveness of current interventions against this pathogen has been the main incentive to develop new methods for the efficient ...
