(Sociedad Chilena de Química, 1984)El presente estudio tiene por objeto correlacionar las propiedades catalíticas de estos complejos ternarios con las concentraciones de las especies provenientes de los equilibrios de disociación del complejo mixto a ...
-
(Sociedad Chilena de Cardiología y Cirugía Cardiovascular, 2000)El objetivo del estudio fue estimar la prevalencia de los distintos alelos del polimorfismo del gen de la enzima convertidora de angiotensina (ECA), inserción/deserción (I/D) y simultáneamente la actividad de ECA plasmática ...
-
(1991)Boldine shows a concentration-dependent relaxation effect on the rat ileum preparation with a pD2 of 3.77 ± 0.12. The alkaloid also produces a concentration-dependent parallel shift of the curve-response to acetylcholine, ...
-
(OXFORD UNIV PRESS, 2006-08)Meeting Abstract
-
(2010)Phytotoxicity due to copper (Cu) is generally associated with visible symptoms such as a decrease in plant shoot and root growth and chlorosis. The application of low levels of Cu or plant exposure to the metal for short ...
-
(2009)Senna crude herbal paste, CIRUELAX®, laxative used in America and Spain, was administered by oral gavage to mice and rats once daily in doses from 2 to 10 g/kg for 7 days. LD50 was rated as higher than 10 g/kg. To determine ...
-
(Springer, 2021)Supercritical carbon dioxide (SCCO2) was studied as a medium for the esterification of eicosapentaenoic acid (n-3 C20:5, EPA) or docosahexaenoic acid (n-3 C22:6, DHA) and caprylic acid (C8:0, CA) in structured triacylglycerols ...
-
(1993)1. 1. In the present study, adenosine modulation on the antinociceptive action of benzodiazepines (BZD) using the writhing test in mice was evaluated. 2. 2. The i.c.v. BZDs tested (diazepam, midazolam and lorazepam) induced ...
-
(HUMANA PRESS INC, 2001-08)Morphological studies of granular neurons of the hippocampus have shown that adrenalectomy (ADX) induces the cell death of granular neurons, an effect prevented by corticosterone replacement. We addressed the hypothesis ...
-
(CAMBRIDGE UNIV PRESS, 1999-02-15)1. The effects of ft tal intravenous treatment with phentolamine or a vasopressinergic V-1-receptor antagonist on the fetal cardiovascular responses to acute hypoxaemia in the llama were investigated. 2. Six llama fetuses ...
-
(2011)The adsorption of hydrophobically modified polyelectrolytes derived from poly(maleic anhydride-alt-styrene) (P(MA-alt-St)) containing in their side chain aryl-alkyl groups onto amino- or methyl-terminated silicon wafers ...
-
(Elsevier B.V., 2016)Adsorption of As (V) by poly (N-octyl-4-vinylpyridinium) bromide (P4VPyC8), used as solid phase, was studied. Determination of As (V) was carried out by direct measurement of the fluorescence intensity on the solid phase. ...
-
(Royal Society of Chemistry, 2020)Because of their photothermal properties, gold nanoparticles (AuNPs) have gained attention regarding their use in drug delivery and therapeutic applications. In this sense, it is interesting to consider their interactions ...
-
(Sociedad Chilena de Quimica, 2012)The efficiency of the adsorption process of the fungicides Captan and Thiram was studied in four Chilean soils from the VI [O'Higgins, (HGS)], VII [Talcarehue, (THL)], VIII [Diguillin, (DIG)] and Metropolitan [Maipo, (MAO)] ...
-
(2009)Glyphosate (N-phosphonometylglycine) is widely used due to its broad spectrum of activity and nonselective mode of action. In Chile it is the most used herbicide, but its adsorption behavior in the abundant and widespread ...
-
(MARCEL DEKKER INC, 2001)This article reports on methabenzthiazuron [1-(1,3-benzothiazol-2-yl)-1,3-dimethylurea] (MBT) adsorption process on six agricultural allophanic and nonallophanic soils. The effect of amendment with exogenous organic matter ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-01-01)We study the thermodynamics and kinetics of the adsorption of a redox couple having quinone nature on glassy carbon electrodes. This couple is produced by the anodic oxidation of mycotoxin ochratoxin A in 10% acetonitrile ...
-
(1988)A study of the adsorption and thermodynamic functions of sulfur dioxide on Aerosil has been made, leading to some conclusions about the mobility of the SO2 molecule. The differential and integral enthalpies and entropies ...
-
(2011)1-Methyl-4-nitro-2-brominemethylimidazole (4-NimMeBr), was electrochemically reduced on mercury, glassy carbon and multiwalled carbon nanotubes (MWCNT) modified electrodes. 4-NimMeBr was adsorbed on the MWCNT modified ...
