(Frontiers Media, 2022)Few kinetic parameters, or reaction rates, are known up to date in detail about 1-chloro and 1-fluoro-2,4-dinitrobenzene (ClDNB and FDNB, respectively) with a series of biothiols in aqueous media. These biological nucleophiles ...
-
(Bioscientifica, 2016)We have previously reported that kisspeptin (KP) may be under the control of the sympathetic innervation of the ovary. Considering that the sympathetic activity of the ovary increases with aging, it is possible that ...
-
(BioScientifica Ltd., 2017)Previous work has demonstrated that the increase in the activity of sympathetic nerves, which occurs during the subfertility period in female rats, causes an increase in follicular cyst development and impairs follicular ...
-
(National Academy of Sciences, 2017)ATP-dependent proteases translocate proteins through a narrow pore for their controlled destruction. However, how a protein substrate containing a knotted topology affects this process remains unknown. Here, we characterized ...
-
(Sociedad Chilena de Cardiología y Cirugía Cardiovascular, 2006)La metaloproteinasa (MMPs) son enzimas proteolíticas que participan en la inestabilidad de la placa aterosclerótica. En cultivos celulares, la actividad de metaloproteinasas-2 y 9 (MMP-2 y MMP-9) aumenta en presencia de ...

(Colegio de Químicos Farmacéuticos de Chile (A:G:), 1985)Es cada vez más evidente que la informática (manejo de información) y los computadores (procesadores de información), están cambiando nuestro sistema de vida. Por ahora podemos decir que el computador nos ofrece las ...
-
(Colegio de Químicos Farmacéuticos de Chile, 1980)La materia viva nos permite fijar un marco de referencia desde el punto de vista de las dimensiones. Las células y bacterias tienen tamaños que varían entre 0,2 y 10 micrones; los componentes celulares y los virus entre ...
-
(Organización de Farmacéuticos Ibero-Latinoamericanos, 1990)Se describe el impacto de la revolución industrial en el ejercicio de la profesión farmacéutica la cual viene también condicionada por la formación académica adquirida. Se revisa criticamente el contenido de los planes ...

-
(American Chemical Society, 2018)© 2018 American Chemical Society. We report the first optical biosensor for the novel and important cardiac biomarker, galectin-3 (Gal3), using the anti-Gal3 antibody as a biorecognition element and surface plasmon resonance ...
-
(MDPI, 2020)Prothrombin-related thrombophilia is a genetic disorder produced by a substitution of a single DNA base pair, replacing guanine with adenine, and is detected mainly by polymerase chain reaction (PCR). A suitable alternative ...
-
(Kluwer Academic Publishers, 1990)Spatial heterogeneity of the Rapel reservoir surface waters is analyzed through Landsat images. The image digital counts are used with the aim or developing an aprioristic quantitative sample design.Natural horizontal ...
-
(Wiley, 2014)A series of lanthanide(III) complexes (Ln = La to Lu) with 2,2 -bipyridyl-6,6 -dicarboxamide ligands were obtained. The X-ray structure of the di(N-ethylanilide) of 2,2 -bipyridyl- 6,6 -dicarboxylic acid is reported. ...
-
Lanthanide sorbent based on magnetite nanoparticles functionalized with organophosphorus extractants (National Institute for Materials Science, 2015)In this work, an adsorbent was prepared based on the attachment of organophosphorus acid extractants, namely, D2EHPA, CYANEX 272, and CYANEX 301, to the surface of superparamagnetic magnetite (Fe3O4) nanoparticles. The ...
-
(Springer-Verlag, 1986)Fusion of a highly purified fraction of rat liver peroxisomal membranes to planar lipid bilayers incorporates large, cation-selective voltage-dependent pores. The PK/PCl ratio of these pores, estimated in KCl gradients, ...
-
(International Union of Crystallography, 2013)In the structure of the title compound, {[Cu2(C10H2O8)- (H2O)6] 4H2O}n, the benzene-1,2,4,5-tetracarboxylate ligand, (btec)4 , is located on a crystallographic inversion centre in a 4-coordination mode. The coordination ...
-
(1987)Soil samples collected in 1982 and 1983 from locations near an industrial park consisting of a Mo ore processing plant and a car battery manufacturing industry were analyzed for total and extractable Mo and Pb. Grass samples ...
-
(EXCERPTA MEDICA INC, 2003-09-15)In patients with hypertension who have the DD-ACE genotype (higher angiotensin-converting enzyme [ACE] activity), plasma levels of angiotensin-(1-7) are 4 times lower than in patients with the II-ACE genotype (lower ACE ...
-
(ROYAL SOC CHEMISTRY, 2012)Five copolymers were prepared by polymerization of azo-benzene methacrylate monomers in solution using AIBN as initiator. The mesophases were observed by a polarizing light microscope which showed tilted smectic C phases ...
