(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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)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)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)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 ...
-
(2009)The antioxidant herbal ingredients are xenobiotics for animals, many of them must be biotransformed to be eliminated, especially lipophilic compounds. Biotransformation of such xenobiotics- occurs mainly in the hepatic ...
-
(2010)Manganese dioxide (δ-MnO2) with magnetic properties has been synthesized by precipitation of MnO2 in the presence of magnetite. The resulting material has a particle size distribution between 0.5 and 5 μm. Magnetization ...
-
(2010)In this study the interaction between new benzimidazole molecules, 2-(2-nitrophenyl)-1H-benzimidazole (NB) and N-benzoyl-2-(2-nitrophenyl)-benzimidazole (BNB), with dsDNA and ssDNA was assessed at pH 7.4. Using differential ...
-
(2010)The inclusion complexes of Luteolin (LU) with cyclodextrins (CDs) including β-cyclodextrin (βCD), hydroxypropyl-β-cyclodextrin (HPβCD) and dimethyl-β-cyclodextrin (DMβCD), Scheme 1, have been investigated using the method ...
