(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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)Autophagic responses are coupled to the activation of the inhibitor of NF-κB kinase (IKK). Here, we report that the essential autophagy mediator Beclin 1 and TGFβ-activated kinase 1 (TAK1)-binding proteins 2 and 3 (TAB2 ...
-
(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 ...
-
(2004)The crystal structure of copper compound, [Cu2(VO 2)(HPO4)2 (NO3)(bpy)2].X was studied. These chemically isostructural systems were obtained by hydrothermal methods, which differ in the solvate molecules stabilizing the ...
-
(2011)The photophysical properties of 4-(benzothiazol-2-yl)-N,N-diphenylaniline, were studied in a series of solvents. UV-Vis absorption spectra are insensitive to solvent polarity whereas the fluorescence spectra in the same ...
-
(2009)Periodic density functional theory calculations on large supercells have been carried out to investigate the atomic and electronic structure of small gold particles (Au2, Au4, Au9, Au13, and Au14) supported on the (001) ...
-
(2011)This study was conducted to determine the use of repeated transvaginal ultrasound-guided cumulus oocyte complex (COC) aspiration on COC recovery rate, in vitro embryo production (IVP) and subsequent pregnancy rates in ...
-
(Elsevier B.V., 2011)The rotating disk sorptive extraction (RDSE) technique was applied to the determination of pesticides in aqueous samples. Pesticides of different polarities were considered in this study: chlorpyrifos, diazinon, fenvalarate, ...
-
(2011)The bleaching of the pyrogallol red (PGR) dye mediated by superoxide anion radicals (O2-) generated from the xanthine/xanthine oxidase system (X/XO) was studied by UV-visible spectrophotometry. The absorption band (at 540 ...
-
(2011)The adsorption of hydrophobically modified polyelectrolytes derived from poly(maleic anhydride-alt-styrene) (P(MA-alt-St)) containing in their side chain aryl-alkyl groups onto amino- or methyl-terminated silicon wafers ...
-
(2011)Structural, magnetic, and powder and single-crystal electron paramagnetic resonance (EPR) studies were performed on [{Cu(bipy)(en)}{Cu(bipy)(H2O)}{VO3}(4)](n) (bipy = 2,2'-bipyridine, en = ethylenediamine), which is a new ...
-
(2011)The aim of this work was to investigate the role of mitochondrial dysfunction in the development of oxidative stress and cytotoxicity induced by indomethacin and to evaluate the potential of an apple peel polyphenol extract ...
-
(2011)The physiologically occurring copper-glutathione complex, [Cu(I)-[GSH]2], has the ability to react continually with oxygen, generating superoxide anions (O 2 -). We addressed here the effects that superoxide removal has ...
-
(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, ...
-
(2004)Three lipid-soluble furan derivatives, 2,5-disubstituted with different n-alkyl chains, and a terminal trimethylammonium group were obtained by reaction of a metalated monoalkylfuran with alkyl dihalides under conditions ...
