-
(2004)Complexes of the type Delta- and Lambda-[Co(diimine)(2)carbohydrate](2+) were synthesized with the diimines: 1,10-phenanthroline and 2,2'-bipyridine and with the carbohydrates: aminosugars, hexoses, pentoses and sucrose, ...
-
(2004)The high temperature antioxidant efficiency of α-tocopherol, α-tocotrienol and a mixture of both on hazelnut oil were evaluated. Crude hazelnut oil (HZO), crude hazelnut oil treated with alumina (THZO), as well as three ...
-
(2004)A standard aqueous extract of Mangifera indica L., used in Cuba as an antioxidant under the brand name of VIMANG®, was tested in vivo for its anti-inflammatory activity using commonly accepted assays. M. indica extract, ...
-
(2004)A rapid method of capillary zone electrophoresis is described to determine the oxidized (GSSG) and reduced (GSH) form of glutathione in plant tissue. In order to separate both analytes in a fused-silica capillary, the pH ...

-
(2004)Inclusion complexation between furnidipine (2,6-dimethyl-4-(2-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylic acid 3-tetrahydrofurfuryl 5-methyl diester), a calcium-channel antagonist, and beta-cyclodextrin (beta-CyD) ...
-
(2004)The effects of electric fields on hydrogen bonding in ammonia-formic acid system, are examined with STO-3G and 6-31 G(d) wavefunctions. This system was used in a previous work to model hydrogen bonding in crystalline amino ...
-
(2004)Histones from the parasitic platyhelminthes, Echinococcus granulosus and Fasciola hepatica, were systematically characterized. Core histones H2A, H2B, H3 and H4, which were identified on the basis of amino acid sequencing ...
-
(2004)The solubilization of p-nitrophenol into the hydrophobic microdomains provided by polyelectrolytes carrying alkyl side chains of different length has been investigated in aqueous solutions of pH 5.0 and 8.0. Under these ...
-
(2004)DFT calculations on Cu4(μ3-X)4L 4 (X = H, CH3, CCH, F, Cl, Br, I; L = NH3, PH3) indicate that, regardless of its nature, X- acts essentially as a two-electron σ-type ligand and that the covalent part of the Cu⋯Cu bonding ...
-
(2004)Reduction of acrylamide formation in potato chips was investigated in relation to frying temperature and three treatments before frying. Potato slices (Tivoli variety, diameter: 37 mm, width: 2.2 mm) were fried at 150°C, ...
-
(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 ...
-
(2004)This article describes the basis and development of the solid dosage form section of an educational CD-ROM, including both the theoretical and self-evaluation sections.
-
(2004)The synthesis and phase characterization of three homologous series of liquid crystalline acrylic and methacrylic monomers, consisting of 21 new compounds are presented. They are based on ω-hexyloxy- and ω-undecyloxysali ...
-
(2004)The oxidation of D-galacturonic acid by Cr-VI yields the aldaric acid and Cr-III as final products when a 30-times or higher excess of the uronic acid over Cr-VI is used. The redox reaction involves the formation of ...
-
(2004)To evaluate the potential use of mesquite (Prosopis chilensis (Mol) Stuntz) seed gum, the behaviour of the gum was studied using two extraction methods (alkaline and acid), different pH values, two concentrations (0.2 and ...
-
(2004)Biomineralization leads to the formation of inorganic crystals with unique, ordered, refined shapes that are regulated by specific macromolecules. This process has been a source of inspiration for exploring novel approaches ...
-
(ROYAL SOC CHEMISTRY, 2004)In Chile, the increasing number of plants for the treatment of wastewater has brought about an increase in the generation of sludge. One way of sludge disposal is its application on land; this, however involves some problems, ...
-
(ROYAL SOC CHEMISTRY, 2004)Following our research on copper, arsenic and antimony in Chilean ecosystems, a study to understand the mobility and transport of these elements from soil to plants was carried out. So, the aim of this study, which follows ...
-
(Sociedad Chilena de la Ciencia del Suelo, 2004)la determinación de la actividad biológica es un mecanismo útil para establecer un seguimiento de la calidad del suelo y ver los posibles efectos de la manipulación de este. Se ha demostrado que la intervención del suelo ...
