(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 ...
-
(Elsevier, 2003)The global electrophilicity power, ω, of a series of dipoles and dipolarophiles commonly used in 1,3-dipolar cycloadditions may be conveniently classified within a unique relative scale. The effects of chemical substitution ...
-
(2002)The global electrophilicity power, ω, of a series of dienes and dienophiles commonly used in Diels-Alder reactions may be conveniently classified within a unique relative scale. Useful information about the polarity of ...
-
(2002)Regional electrophilicity at the active sites of the reagents involved in polar Diels-Alder processes may be described on a quantitative basis using an extension of the global electrophilicity index recently introduced by ...
-
(2008)Data on wealth distributions in trading markets show a power law behavior x- (1+α) at the high end, where, in general, α is greater than 1 (Pareto's law). Models based on kinetic theory, where a set of interacting agents ...
-
(ALÖKI Kft., 2018)Most of the world's catches of sharks are incidentally taken by tuna fishing gear, constituting bycatches that increase the extinction risk of several species of shark. This not only alters ecosystem functions by removing ...
-
(Peking University Press, 2018)Quantitative correlation of several theoretical electrophilicity measures over different families of organic compounds are examined relative to the experimental values of Mayr et al. Notably, the ability to predict these ...
-
(AMER PHYSICAL SOCIETY, 2010-01-27)We perform density-functional-theory calculations of electronic core levels to obtain the tellurium x-ray photoelectron spectra in the amorphous solar-energy materials CdTeOx x=0.2, 1, 2, and 3 . We quantify the distribution ...
-
(2002)We present quantitative information on the natural history of a host-parasite interaction that consists on the holoparasitic mistletoe Tristerix aphyllus (Loranthaceae) and its cacti host species. More specifically, we ...

(1995)It is pointed out that the action recently proposed by Bañados, Teitelboim, and Zanelli for the study of black holes in odd dimensions higher (and lower) than four provides a natural quantization for the gravitational ...
