(2009)Primary Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disease affecting mainly the exocrine glands. Its physio-pathology is poorly understood and most of the knowledge has been related to the inflammatory ...
-
(Elsevier, 2009)In this work we report the optimization of a chitosan (CHI) and carbon nanotubes (CNT) modified electrode, CNT-CHI, to study the dsDNA interaction with methylene blue (MB), a well-known DNA intercalator. The analytical ...
-
(2009)Glyphosate (N-phosphonometylglycine) is widely used due to its broad spectrum of activity and nonselective mode of action. In Chile it is the most used herbicide, but its adsorption behavior in the abundant and widespread ...
-
(2009)The exposure of organisms to ultraviolet radiation (UVR) is characterized by the climatology (annual cycle) and the variance (anomalies) of biologically-weighted irradiances at eight geographical locations in austral South ...
-
(Verlag der Zeitschrift fur Naturforschung, 2004)The effect of different photon flux densities (PFD) and temperatures on the relative growth rate (RGR) and the concentration of three halogenated monoterpenes in samples of Plocamium cartilagineum L.( Dixon), a marine alga ...
-
(2009)Photoreduction of oxoisoaporphine (OIA) (l-aza-benzo-[de]anthracen-7-one) and its 5-methoxy (5-MeOOIA) derivative by selected amines (two non-a-hydrogen-donating amines (l,4-diaza[2.2.2]-bicyclooctane (DABCO) and ...
-
(2009)A structural and magnetic characterization of a trinuclear chiral Mn(ll) formate three-dimensional framework exhibiting a triangular arrangement is presented. Compound Na3[Mn3(HCOO)9] was obtained by solvothermal synthesis ...
-
(2009)Four different 5-nitroindazole derivatives (1-4) and its inclusion with Heptakis(2,6-di-O-methyl)-beta-cyclodextrin (DM beta CD) were investigated. The stoichiometric ratios and stability constants describing the extent ...
-
(2009)This study aims to describe the mass transfer in a membrane-based solvent extraction system for the extraction of molybdenum(VI) from aqueous solutions, identifying chemical kinetics of the complex formation at the interface. ...
-
(2009)The complex [FeII(Imz-phen)3](PF6)2, (Imz-phen = imidazolidine-[4,5-f]-1,10-phenanthroline) has been prepared and characterized using X-ray diffraction, UV–vis and IR spectroscopy, elemental analysis, fast atomic bombardment ...
-
(Academic Press, 2009)Chilean jack mackerel (Trachurus murphyi) is an underutilised medium-fat fish species, captured in large volumes but commercialised in the fish meal and surimi industries. This study provides a first approach including a ...
-
(2009)A neutral fraction (PS-SI) (0.3 g/L) with MW of 74 kDa, which contained galactose, arabinose, mannose, and glucose in the molar ratio of 1.0:0.6:0.4:0.2 was obtained by treatment of the whole polysaccharide extracted from ...
-
(2006)Reduction in corticosterone by acute adrenalectomy (5 d) promotes apoptosis in dentate gyrus (DG) granular neurons, an effect concomitant with variations in the expression of the Bcl-2 gene family implicated in apoptotic ...
-
(2009)Previously, we have identified a series of 5-nitroindazoles with good antiprotozoal activities, against Trypanosoma cruzi epimastigotes and Trichomonas vaginalis. Most of them have shown very low unspecific toxicity on ...
-
(2009)Two Cys-containing analogues of the anticancer drug Kahalalide F are synthesized and conjugated to 20 and 40 nm gold nanoparticles (GNPs). The resulting complexes are characterized by different analytical techniques to ...
-
(2009)New indazole derivatives have been developed to know about structural requirements for adequate anti-Trypanosoma cruzi activity. In relation to position 1 of indazole ring, we have observed that a butylaminopentyl substituent ...
-
(Royal Society of Chemistry, 2009)A new extended metal-organic framework [Cu(H(2)btec)(bipy)](infinity) (1) (H(4)btec=1,2,4,5-benzenetetracarboxylic acid; bipy= 2,2'-bipyridine) has been hydrothermally synthesized. Violet crystals are formed in a monoclinic ...
-
(2009)A commercial diet including synthetic antioxidants (BHT-ethoxyquin mixture) (diet I) was provided to coho salmon (Oncorhynchus kisutch) in parallel with two diets including natural antioxidants (tocopherol isomers rich ...
-
(2009)Eight new platinum(II) complexes with 3-(5-nitrofuryl)acroleine thiosemicarbazones showing anti-trypanosomal activity were synthesized, characterized and in vitro evaluated. Most of the complexes showed IC50 values in the ...
-
(2006)NFκB is a participant in the process whereby cells adapt to stress. We have evaluated the activation of NFκB pathway by hyperosmotic stress in cultured cardiomyocytes and its role in the activation of caspase and cell ...
