(1983)1. 1. Prazosin, haloperidol, propranolol or timolol had no effect on the electrically evoked muscular twitch. 2. 2. Atropine was able to antagonize competitively acetylcholine (pA2 = 9.29 ± 0.30). 3. 3. The muscular twitch ...
-
(2010)Pomegranate (Punica granatum) bioactive compounds (polyphenols and anthocyanins) of juice (PJ) and ethanolic extracts (PE) were encapsulated with maltodextrin (MD) or soybean protein isolates (SPI) by spray drying using a ...
-
(2011)Objectives This study was designed to investigate the potential protective effect of a methanolic extract of Peumus boldus leaves on UV light and nitric oxide (NO)-mediated DNA damage. In addition, we investigated the ...
-
(2012)Gallic acid (GA) was encapsulated with native starch (NS), native inulin (NIn), acetylated starch (AS) or acetylated inulin (AIn) (two substitution degrees each) by spray-drying, and a 2 2 statistical factorial design was ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
