(ELSEVIER SCIENCE BV, 2009-11-03)We investigated the role of Ca2+ in generating reactive oxygen species (ROS) induced by hyposmotic stress (Hypo) and its relationship to regulatory volume decrease (RVD) in cardiomyocytes. Hypo-induced increases in cytoplasmic ...
-
(Elsevier, 2013)In the present work we synthesized a series of hydroxy-3-arylcoumarins (compounds 1–9), some of them previously described as MAO-B selective inhibitors, with the aim of evaluating their antioxidant properties. Theoretical ...
-
(Elsevier Inc., 2017)© 2017 Elsevier Inc. American Trypanosomiasis is a chronic infection discovered and described in 1909 by the Brazilian scientist Carlos Chagas. It is caused by the protozoan parasite Trypanosoma cruzi. Although it affects ...
-
(Sociedad Chilena de Química, 1998)The potential energy surface of hstamine monocation is calculated by MNDO types methodologies and by the Reaction Field model at CNDO/2 level, in order to rationalize the experimental findings about the relative abundance ...
-
(Bentham Science Publ, 2015)Electron spin resonance (ESR), called also electron paramagnetic resonance (EPR) together with the spin trapping technique, has allowed us to study and understand how free radicals are involved in various pathologies. In ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2007-05)The aim of this paper is to describe the inclusion properties and the factors affecting the complexation selectivity and stabilization of catechin (CA) into beta-cyclodextrin (beta-CD) and two of its derivatives, namely ...
-
(MDPI AG, 2015)In the present work we synthesized a selected series of hydroxylated 3-phenylcoumarins 5–8, with the aim of evaluating in detail their antioxidant properties. From an in depth study of the antioxidant capacity data ...
-
(CHEMICAL SOC JAPAN, 2002-09)Hydroxyl and phenyl radical spin trapping rates by alpha-phenyl-N-t-butylnitrone (PBN, N-benzylidene-t-butylamine N-oxide) and its analogs were determined using a competitive trapping method. Hydroxyl radical was generated ...
-
(American Chemical Society, 2013)A series of novel hydroxy-coumarin−chalcone hybrid compounds 2a−i has been synthesized by employing a simple and efficient methodology. An electrochemical characterization using cyclic voltammetry and ESR spectroscopy ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(ELSEVIER SCIENCE BV, 2006-09-29)Theoretical studies of molecular conformations and electronic properties calculations of eight 5-nitrofuryl thiosemicarbazone free radicals, by means of ab initio (R/UHF), and DFT (R/UB3LYP) methods are presented and ...
-
(ELSEVIER SCIENCE BV, 2007-10-25)The aurophilic attraction and the spectroscopic properties of [AU(3)(MeN=COMe)(3)](n) (n = 1-4) were studied at the MP2 and density functional theory (B3LYP and PBE) levels. Theoretical calculations at the MP2 level are ...
-
(ELSEVIER SCIENCE BV, 2006-05-30)The electronic structure and the spectroscopic properties of [M(CN)(2)](n)(-n), (M = Au(I), Ag(I); n = 1-3) were studied using density functional theory (DFT) at the B3LYP level. The absorption spectrums in these complexes ...
-
(Springer, 2013)The main purpose of this work was to study the chiral recognition thermodynamics of inclusion complexes formed by flavanones and b-cyclodextrins, and its relation with the inclusion geometries, through NMR experiments. By ...

Use of Pyrogallol Red and Pyranine as Probes to Evaluate Antioxidant Capacities towards Hypochlorite (2013)Hypochlorite is a strong oxidant able to induce deleterious effects in biological systems. The goal of this work was to investigate the use of PGR and PYR as probes in assays aimed at evaluating antioxidant activities ...
-
(Springer, 2014)Parasitic illnesses are major causes of human disease and misery worldwide. Among them, both amebiasis and Chagas disease, caused by the protozoan parasites, Entamoeba histolytica and Trypanosoma cruzi, are responsible ...
