-
(2012)The leading cause of death in diabetic patients is cardiovascular disease; diabetic cardiomyopathy is typified by alterations in cardiac morphology and function, independent of hypertension or coronary disease. However, ...
-
(2012)Shigella flexneri causes bacillary dysentery in humans. Essential to the establishment of the disease is the invasion of the colonic epithelial cells. Here we investigated the role of the lipopolysaccharide (LPS) O antigen ...
-
(2012)A series of fused tri- and tetracyclic indazoles and analogues compounds (NID) with potential antiparasitic effects were studied using voltamperometric and spectroscopic techniques. Nitroanion radicals generated by cyclic ...
-
(2012)Efficient lignin depolymerization is unique to the wood decay basidiomycetes, collectively referred to as white rot fungi. Phanerochaete chrysosporium simultaneously degrades lignin and cellulose, whereas the closely related ...
-
(2012)EPR measurements have been performed on single crystals of [Cu(L-tyrosine)2]az at 33.8 GHz and at room temperature. The EPR spectra display partially resolved EPR lines for most orientations of the magnetic field in the ...
-
(2012)Introduction: Acidic and metal(oid)-rich topsoils resulted after 34 years of continuous operations of a copper smelter in the Puchuncaví valley, central Chile. Currently, large-scale remediation actions for simultaneous ...
-
(2012)Although substrate conversion mediated by human monoaminooxidase (hMAO) has been associated with the deprotonated state of their amine moiety, data regarding the influence of protonation on substrate binding at the active ...
-
(Elsevier, 2010)The present manuscript describes studies of the electron transfer kinetics at gold electrodes modified by electrostatic self-assemblies of polyethylenimine (PEI), DNA and gold nanoparticles (NP) by Scanning Electrochemical ...
-
(2012)The intracellularly-occurring Cu(I)-glutathione complex (Cu(I)-[GSH] 2) has the ability to reduce molecular oxygen into superoxide. Removal of such radicals leads to the irreversible conversion of Cu(I)-[GSH] 2 into the ...
-
(2011)This work reports the electrochemical response of the complex between dsDNA and PEI formed in solution and at the surface of glassy carbon electrodes (GCE) modified with a dispersion of multi-walled carbon nanotubes in ...
-
(2012)The pyrolysis of several physical mixtures of AuCl(PPh 3) with polymeric [NP(O 2C 12H 8)] n or cyclic N 3P 3(O 2C 12H 8) 3 phosphazenes, formed as solid powders or films with different molar ratios, have been studied under ...
-
(2012)In this study, a methodology for pressurized solvent extraction of alkylphenols (APs) and alkylphenol ethoxylates (APEOs) from biosolids was optimized by utilizing a biosolid natively containing these compounds at a high ...
-
(2010)Hemocyanins are copper-containing glycoproteins in some molluscs and arthropods, and their bestknown function is O2 transport. We studied the site of their biosynthesis in the gastropod Concholepas concholepas by using ...
-
(2011)In this work, two simple and fast methods for the determination of candesartan cilexetil in pharmaceutical forms, having it as a sole drug, were developed and validated. Candesartan cilexetil is a prodrug hydrolyzed to ...
-
(2011)The complexes Diaqua-bis(5-nitroimidazole)-copper(II)-dinitrate (1); Tetrakis(4- phenylimidazole)-copper(II)-dinitrate, ethanol solvate (2); Bis(4-phenylimidazole)-bis(acetate)-copper(II) (3); Hexakis(4-phenylimidazole)- ...
-
(2012)The inhibition of aggregation and disaggregation effect of a β-sheet breaker was evaluated by in situ electrochemistry of the Aβ 1-42 peptide. The exposition of 10tyr residue was followed using a carbon nanotubes modified ...
-
(2012)A series of novel benzo[b]thiophen-2-yl-3-(4-arylpiperazin-1-yl)-propan-1- one derivatives 6a-f, 7a-f and their corresponding alcohols 8a-f were synthesized and evaluated for their affinity towards 5-HT 1A receptors. The ...
-
(2012)Gold nanoparticles (AuNPs) have been extensively used in biological applications because of their biocompatibility, size, and ease of characterization, as well as an extensive knowledge of their surface chemistry. These ...
-
(2011)The physicochemical properties of 4-hydroxy-7-methoxy-3-phenyl-2H-chromen- 2-one (4HC) and β-cyclodextrins (CDs) inclusion complexes were investigated. The phase solubility profile of 4HC with β-cyclodextrin derivatives ...
-
(2011)In this paper, the uptake of Cu(II) ions from an acidic aqueous solution using a continuous column packed with microcapsules containing the chelating extractant LIX-860 N-IC was examined. A simple, economical method was ...
