-
(Taylor and Francis Inc., 2010)A kinetics analysis was conducted for the recovery of zinc (II) ions from a mine drainage sample by a liquid surfactant membrane containing di-(2-ethylhexyl)phosphoric acid as a carrier extractant and Span-80 as the ...
-
(2010)An extraction method of polycyclic aromatic hydrocarbons (PAHs) from biosolids, based on continuous pressurized solvent extraction (PSE), was developed and optimized through an experimental design and followed by gas ...
-
(Sociedade Brasileira de Quimica, 2010)The aim of this study was to determine the influence of the substituent groups on the photostability of eight boldine derivatives, including some oxazole and oxazinone derivatives, in order to increase the sunscreen ...
-
(2009)We report a novel analytical procedure to measure the surface areas of coexisting lipid domains in giant unilamellar vesicles (GUVs) based on image processing of 3D fluorescence microscopy data. The procedure involves the ...
-
(Elsevier B.V., 2010)This work describes the preparation of a new tetraruthenated porphyrin and the corresponding polymeric film. This macromolecule consists of a Ni(II) tetrapyridylporphyrin coordinated to four [Ru(5-NO2-phen) 2Cl]+ moieties. ...
-
(2010)The importance of H2 production as an energy carrier in the future has driven the attention to reforming systems, such as steam reforming, partial oxidation or oxidative steam reforming of ethanol, considering thermodynamic ...
-
(2011)Niemann-Pick type C (NPC) is a neurodegenerative disease characterized by the intralysosomal accumulation of cholesterol leading to neuronal apoptosis. We have previously reported the activation of the c-Abl/p73 proapoptotic ...
-
(2010)Quinoa, Chenopodium quinoa Willd., is an Amaranthacean, stress-tolerant plant cultivated along the Andes for the last 7000 years, challenging highly different environmental conditions ranging from Bolivia, up to 4.500 m ...
-
(2010)To improve downstream processing, protein engineering can be used to modify particular properties of a protein, such as specific affinity, charge, or hydrophobicity. The most common modification involves the peptide tags ...
-
(2010)Prompted by the recently reported capacity of the physiologically occurring Cu(I)-[glutathione]2 complex (Cu(I)-[GSH)]2) to reduce oxygen, the effect of various GSH-binding metals (Co2+, Cd2+, Zn2+, Pb2+, Al3+, Hg2+ and ...
-
(2010)Hyperosmotic stress promotes rapid and pronounced apoptosis in cultured cardiomyocytes. Here, we investigated if Ca2+ signals contribute to this response. Exposure of cardiomyocytes to sorbitol [600 mosmol (kg water)(-1)] ...
-
(2010)Cyclic Voltammetry (CV) and electron spin resonance (ESR) techniques were used in the investigation of several potentially antiprotozoal nitro derivatives of dihydroquinoxaline and indazole. A self-protonation process ...
-
(2010)The aim of the present study was to identify the possible mechanisms by which certain estradiol receptor (ER)-positive mammary tumor cells remain resistant to treatment with anti-estrogens or inhibitors of local estradiol ...
-
(2010)Apple peel is a waste product from dried apple manufacture. The content of phenolic compounds, dietary fiber, and mineral are higher in apple peel, compared to other edible parts of this fruits. The objective of this study ...
-
(Elsevier B.V., 2010)An analytical methodology based on differential pulse voltammetry (DPV) on a glassy carbon electrode and the partial least-squares (PLS-1) algorithm for the simultaneous determination of levodopa, carbidopa and benserazide ...
-
(Elsevier B.V., 2010)In this work, the electrochemical behavior and the analytical application of atomoxetine, a selective noradrenaline reuptake inhibitor, are studied. Atomoxetine, studied by differential pulse voltammetry and cyclic voltammetry ...
-
(Elsevier Ltd, 2009)The simultaneous occurrences of electrochemical reactions responsible for corrosion of carbon steel in NaCl solutions have been analyzed on the basis of the mixed potential theory in order to determine the combined effect ...
-
(2010)Background & aims: Gold nanoparticles (GNPs) have promising applications for drug delivery as well as for the diagnosis and treatment of several pathologies, such as those related to the CNS. However, GNPs are retained in ...
-
(2010)Functionalization of gold nanoparticles (AuNPs) with both a targeting peptide (an analogue of the peptide Bombesin) and a drug peptide ligand (an analogue of the RAF peptide) with the aim of improving selectivity in the ...
-
(Elsevier B.V., 2010)The electrochemical behavior and the analytical application of the selective serotonin agonist naratriptan (N-methyl-3-(1-methyl-4-piperidyl)indole-5-ethanesulfonamide) are presented herein. Naratriptan exhibits an anodic ...
