-
(Springer, 2017)Ischemic preconditioning (IPC) limits myocardial infarct size through the activation of the PI3K-Akt signal cascade; however, little is known about the roles of individual PI3K isoforms in cardioprotection. We aimed, ...
-
(SOC MEDICA SANTIAGO, 2011-04)Complications and mortality of heart failure are high, despite the availability of several forms of treatment. Uric acid, the end product of purine metabolism would actively participate in the pathophysiology of heart ...
-
(2011)Mollusks are good food and also products of great commercial value. However, information about the nutritional value of these shellfish as foods is scarce. This work focused on the chemical characterization of scallops, ...
-
(1995)A procedure for recovery and separation of molybdenum (VI) and copper (II) from acid leaching residual solution of Chilean molybdenite concentrate by solvent extraction is studied. The process for the recovery of metals ...
-
(Elsevier, 2018)Stromal-interaction molecule 1 (STIM1)-mediated store-operated Ca2+ entry (SOCE) plays a key role in mediating cardiomyocyte hypertrophy, both in vitro and in vivo. Moreover, there is growing support for the contribution ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1999)Reaction of (CO)(9)Co-3(mu(3)-CCOOH) with metal trifluoroacetates leads to the isolation of Cr-2{mu-OOC-CCo3(CO)(9)}(2){mu-OOCCF3}(2)(THF)(2), 1, and Sm-2{mu-OOCCCo3(CO)(9)}(2){mu-OOCCF3}(4){(CO)(9)Co3CCOOH}(2)(THF)(2). ...
-
(Univ. Distrital Francisco Jose de Caldas, 2016)Green Chemistry, as a research area, understood as the development of methodologies to modify products or processes in order to reduce or eliminate the risks posed to the environment and human health. Thus it is allowing ...
-
(Elsevier Ltd, 2014)The synthesis, magnetic and structural characterization of two tetrameric copper(II) complexes {N(C4H9)4}-[Cu 2(LH)2(μ4-Br)Cu2(LH) 2](PF6)4 (1) and [Cu2(LH) 2(μ4-Cl)Cu2(LH)2](Cl) 2(PF6) (2) is described. LH stands for the ...
-
(American Geophysical Union, 2020)Information about end-of-winter spatial distribution of snow depth is important for seasonal forecasts of spring/summer streamflow in high-mountain regions. Nevertheless, such information typically relies upon extrapolation ...

-
(Elsevier, 2021)Cocoa beans contain antioxidant molecules with the potential to inhibit type 2 coronavirus (SARS-CoV-2), which causes a severe acute respiratory syndrome (COVID-19). In particular, protease. Therefore, using in silico ...
-
(Springer, 2013)A theoretical study of the magnetic properties, using density functional theory, of a family of trinuclear μ3-OH copper(II) complexes reported in the literature is presented. The reported X-ray crystal structures ...
-
(Hindawi Limited, 2017)© 2017 Maximiliano Martínez-Cifuentes et al. The mandatory presence of a chlorine atom on the aromatic ring of 6-hydroxy-3-formyl angular chromones, on the respiration inhibition of mammary carcinoma mouse, is explained ...
-
(JOHN WILEY & SONS INC, 2007-01)We studied the attraction between [C2Hn] and Tl(I) in the hypothetical [C2Hn-Tl](+) complexes (n = 2,4) using ab initio methodology. We found that the changes around the equilibrium distance C-Tl and in the interaction ...
-
(JOHN WILEY & SONS INC, 2009-03-05)The platinum-platinum attraction and the spectroscopic properties of [Pt-3(mu-CO)(3)(CO)(3)](n)(-2) (n = 3-5) were Studied at the PBE level. Theoretical calculations are in agreement with experimental geometries. The ...
-
(ELSEVIER, 2006-10-01)Density functional theory (DFT) calculations on the tetranuclear Ni(II) complex [Ni-4(C5H11O3)(4) (CH3CN)(4)](NO3)(4)center dot 1.33NaNO(3), have been made in order to explain the exchange magnetic phenomenon. Two ferromagnetic ...
-
(JOHN WILEY & SONS INC, 2005-05-15)The electronic structure and the spectroscopic properties of [Au-2(CS3)(2)](-2), [Au-2(pym-2-S)(2)] (pym = pyrimidethiolate), [Au-2(dpm)(2)](+2) (dpm = bis(diphosphino)methane) were studied using density functional theory ...
-
(2006)The exchange interactions in a Ni12 complex have been studied by using theoretical methods based on density functional theory. The calculated J values reproduce correctly the S = 12 ground state of this system found ...
-
(JOHN WILEY & SONS INC, 2007-05)Ab initio calculations suggest that a series of complexes of type [Pt(PH3)(3)-MPH3](+) (M = Au, Ag, Cu) are stable. We found that changes around the equilibrium distance Pt-M and in the interaction energies are sensitive ...
-
(ELSEVIER SCIENCE BV, 2007-02-18)We studied the attraction between [Pt(PH3)(3)] and the metals (Hg(0) and Au(-I)) in the hypothetical [Pt(PH3)(3)M] isoelectronic complexes using ab initio methodology. We found that the changes around the equilibrium ...
