(2011)The turbot (Scophthalmus maximus) is a kind of flatfish that is well adapted to intensive farm culture. After the harvest it is necessary to know the physicochemical, biochemical and technological properties and if during ...
-
(1983)The a.c polarographic method has been applied in the study of the glutathione-ampicillin interaction at pH 7.4 and 37°C. Ampicillin shifted the peak potentials of glutathione to less negative values. A linear relation was ...
-
(American Chemical Society, 1997)In recent papers we defined a theoretical frame aimed at characterizing the hardness and potential energy profiles along a reduced reaction coordinate (omega) varying from 0 to 1. In this paper we generalize that model to ...
-
(2010)Pretreatment of lignocellulosic materials is an important step to achieve higher amounts of simple sugars, mono- and disaccharides, for obtaining ethanol as a biofuel, via enzymatic hydrolysis. The study introduces a concept ...
-
(Sociedad Chilena de Quimica, 2010)D-Glucose derivatives 1,2:5,6-di-O-isopropyline-a-D-glucofuranose (1) and 1,2-O-isopropyline-a-D-glucofuranose (2) with Ti(IV) are chiral catalysts in the addition of diethylzinc to benzaldehyde. The Ti(IV)-carbohydrate ...

(2009)Recent studies have demonstrated that neurotrophins (NTs) and their NTRK tyrosine kinase receptors, thought to be exclusively required for the development of the nervous system, are also involved in controlling ovarian ...
-
(Royal Society of Chemistry, 2010)A novel iridium complex incorporating a di(2-picolyl)anilino-appended bipyridine ligand was synthesized and its optical properties studied. The presence of Zn2+ ions specifically perturbs the excited state, giving rise to ...
-
(2009)Bensulfuron-methyl sorption was studied in Andisol and Ultisol soils in view of their characteristic physical and chemical properties, presenting acidic pH and variable charge. Humic and fulvic acids (HA and FA) and humin ...
-
(2009)An effective extraction method was devised for the determination of organophosphorus pesticides (OPPs) in olive and avocado oil samples, using atmospheric pressure microwave-assisted liquid-liquid extraction (APMAE) and ...
-
(2010)Metsulfuron-methyl sorption kinetic was studied in Andisol and Ultisol soils in view of their distinctive physical and chemical properties: acidic pH and variable surface charge. Different kinetic models were applied to ...
-
(2010)Metsulfuron-methyl sorption/desorption behavior was studied through batch sorption experiments in three typical volcanic ash-derived soils belonging to Andisol and Ultisol orders. Their distinctive physical and chemical ...
-
(2009)The catalytic behaviour of different complexes of Palladium(II) containing mono or bidentate phosphorus or nitrogen ligands in the methoxycarbonylation reaction is examined. The pre-catalysts containing either a diphosphine ...
-
(2009)Although ovarian nerve growth factor (NGF) facilitates follicular development and ovulation, an excess of the neurotrophin in the rodent ovary reduces ovulatory capacity and causes development of precystic follicles. Here ...
-
Anti-inflammatory effects of ethanolic extract and alkamides-derived from Heliopsis longipes roots (2009)Ethnopharmacological relevance: Heliopsis longipes (A. Gray) Blake (Asteraceae) is a broadly used species in the Mexican, Central and South American Traditional Medicine for its anaesthetic, analgesic, anti-inflammatory ...
-
(2009)The synthesis and the experimental and theoretical characterization of ruthenium hydride complexes containing phosphorus and polypyridine ligands [RuH(CO)(N-N)(PPh3)2]+ with N-N = dppz 1, dppz-CH3 2 (2.1 isomer), dppz-Cl ...
