(Universisdad de Chile, 1975)Este trabajo se presentan detalles de la purificación y caracterización de la glucoquinasa (ATP: D-gluconasa 6-fosfotrasferasa EC 2.7.1.2.) de hígado de perro. La enzima ha sido purificada cerca de 11.000 veces obteniéndose ...
-
(Universidad de Chile, 2006)Al alcanzar un tamaño determinado la célula bacteriana se divide en dos células hijas prácticamente idénticas entre sí y, a su vez, iguales a la célula que les dio origen. Este proceso se caracteriza por una notoria ...

(1992)Two isoenzymes of ATP-diphosphohydrolase (apyrase) were extracted and purified from S. tuberosum var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were 1.0 (apyrase B) and ca 15.0 (apyrase A). They were ...
-
(Public Library Science, 2016)T helper type 17 (Th17) lymphocytes, characterized by the production of interleukin-17 and other pro-inflammatory cytokines, are present in intestinal lamina propria and have been described as important players driving ...

Putative ClC-2 chloride channel mediates inward rectification in Drosophila retinal photoreceptors (SPRINGER, 2005-10)We report that Drosohhila retinal photoreceptors express inwardly rectifying chloride channels that seem to be orthologous to mammalian CIC-2 inward rectifier channels. We measured inwardly rectifying Cl- currents in ...
-
(Elsevier, 2020)The PyProcar Python package plots the band structure and the Fermi surface as a function of site and/or s,p,d,f - projected wavefunctions obtained for each k-point in the Brillouin zone and band in an electronic structure ...

(PERGAMON-ELSEVIER SCIENCE, 2005-10-03)Three naturally occurring pyranosyl-like polyhalogenated metabolites 1-3 as well as their likely biogenetic precursor, the linear compound 4, have been isolated from the red alga Ptilonia magellanica. They are the first ...
-
(1979)Quadrupole moments, dipole quadrupole polarizability A, and quadrupole polarizability C values have been obtained for a set of organic molecules, in both the ground and first singlet excited states, by means of ...
-
(2007)By means of qualitative techniques we analyze the consequences of inducible defenses of species embedded in trophic chains on the community stability and responses of population equilibrium densities to press perturbations. ...
-
(Elsevier, 2014)The development of quantitative temperature reconstructions in regions of paleoclimate interest is an important step for providing reliable temperature estimates in that region. Fossil chironomid assemblages have been studied ...
-
(Universiti Putra Malaysia, 2016)© 2008 IFRJ.The prevalence of metabolic syndrome, hypertension, heart disease and diabetes has been increasing rapidly in Chile in recent years. The rate of increase has paralleled the replacement of traditional Mediterranean ...
-
(2010)In a previous work (L. R. Domingo, M. J. Aurell, P. Perez and R. Contreras, Tetrahedron 2002, 58, 4417) we proposed that the difference in global electrophilicity index be taken as a measure of the polarity at the transition ...
