(MDPI, 2020)The search for sensitive and rapid analytical techniques for the determination of natural antioxidants is an area in constant growth due, among other aspects, to the complexity of plant matrices. In this study, silver ... -
Real-space approach to the reaction force: understanding the origin of synchronicity/nonsynchronicity in multibond chemical reactions
(American Chemical Society, 2020)In this article, we present a complementary analysis based on the reaction force F(xi)/reaction force constant kappa(xi) and noncovalent interactions (NCI) index to characterize the energetics (kinetic and thermodynamics) ... -
Pro-fibrotic effect of oxidized LDL in cardiac myofibroblasts
(Elsevier, 2020)Inflammatory signals associated with cardiac diseases trigger trans-differentiation of cardiac fibroblasts to cardiac myofibroblasts. Cardiac myofibroblasts are the main cell type involved in the development of cardiac ... -
Importance of the electrolyte cation on the non-covalent interactions in the electrooxidation of 1-heptanol on gold in 0.1 M alkali metal hydroxides
(Elsevier, 2020)In order to determine the possible non-covalent influence of the alkali metal cation on the electrooxidation of 1-heptanol on gold in alkali metal hydroxides, 0.1 M MOH solutions, where M = Li, Na, K, Rb, and Cs, have been ... -
Influence of DMbetaCD on the Interaction of Copper(II) Complex of 6-Hydroxychromone-3-carbaldehyde-3-hydroxybenzoylhydrazine with ctDNA
(American Chemical Society, 2020)The interaction mechanism between a scarcely soluble copper(II) complex of Cu(II)-6-hydroxychromone-3carbaldehyde-(3'-hydroxy)benzoylhydrazone( CuCHz) in aqueous solution and its DM beta CD complex was studied in the ... -
Electrochemical, ESR, theoretical studies and in vitro anti-t. cruzi activity of 2-Organometallic-5-Nitro-benzimidazoles
