(PERGAMON-ELSEVIER SCIENCE LTD, 2008-08)Cyclic voltammetry and electron spin resonance techniques were used in the investigation of novel 3-alkoxy- and 3-hydroxy-1-[omega-(dialkylamino)alkyl]-5-nitroindazole derivatives. A self-protonation process involving the ...
-
(ELSEVIER SCIENCE BV, 2004-01)The aim of this work was to evaluate the possibility of using mixtures and/or polyelectrolyte complexes from both chitosan-alginate and chitosan-carrageenan as prolonged drug release systems. Different dissolution profiles ...
-
(2016)The aim of this study was to assess the differences in qualitative-quantitative composition of triterpenoids and total phenolic contents, together with anti-inflammatory activity of Ugni molinae leaves obtained from ten ...

(2009)HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a progressive CNS disease leading to corticospinal tract degeneration. Various degenerative diseases have increased neurofilament subunit concentration ...
-
(Springer, 2016)A comparative study about the electrochemical response of glassy carbon electrode modified with four different carbon nanomaterial (CNM) against dsDNA is reported. The CNM used were oxidized and nonoxidized multiwalled ...
-
(Elsevier Ltd, 1998)Cobalt phthalocyanine (CoPc) and cobalt naphthalocyanine (CoNPc) exhibit different redox and electronic properties. Redox processes on CoPc are more reversible than on CoNPc. The pH dependence of those processes is also ...
-
(Elsevier, 2013)tThis review present a critical comparison of the electrochemical behavior and analytical performance ofglassy carbon electrodes (GCE) modified with carbon nanotubes (CNTs) dispersed in different polymers:polyethylenimine ...
-
(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 ...
-
(2010)Olive tree varieties that were cultivated only in the Mediterranean basin a few decades ago are now planted in the Southern Hemisphere as well. The chemical composition of the oils produced in countries as far distant as ...
-
(1989)1. 1. Apyrase (ATP: diphosphohydrolase) has been found in the microsomal fraction of rat salivary gland, mammary gland and uterus. 2. 2. This enzyme, already described in plant tissues, is mainly present as a soluble ...
-
(1993)1. Liver microsomes from alloxan or streptozotocin diabetic rats displayed differential drug metabolizing abilities in vitro. 2. Only streptozotocin liver microsomes exhibited changes in the cytochrome P-450 normal spectral ...
-
(Wiley, 2015)The objectives of this study were to determine the physicochemical composition, phenolic, tocopherol, flavonoid, flavanol, dietary fiber and β-carotene contents, as well as the antioxidant activity of three olive-waste ...
-
(2009)Computed bond lengths and angles of methyl ethyl and dimethyl triphenyl phosphonium ylidic diesters, 1b, c, respectively, are similar to those in the crystal, as for the diethyl ester, 1a, where both acyl oxygens are anti ...
-
(American Oil Chemists' Society, 1997)Two Rancimat evaluation modes, the induction period (IP), and the time needed to achieve a selected difference in conductivity (tΔK) were compared for assessing relative stability of anchovy sardine, and hake liver oils. ...
-
(ASSOC BRAS DIVULG CIENTIFICA, 1996-05)ATP-diphosphohydrolase (apyrase, EC 3.6.1.5) has both ATPase and ADPase activity that are stimulated by bivalent metals, with Ca2+ being the most effective. The possible physiological function of this enzyme, associated ...
-
