(2012)A packaging system combining a polyphenol-rich film and vacuum (PPRF-VP) was applied to farmed coho salmon (Oncorhynchus kisutch) muscle for an 18-month storage (-18 degrees C). For it, two different concentrations of ...
-
(2012)The effect of mine tailings and sewage sludge was evaluated on sorption, desorption, availability and distribution of copper in two soils, one high (sandy soil) and one low in copper (clay soil). In both soils contaminated ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(Verlag der Zeitschrift fur Naturforschung, 2011)Neutral tribromo(2-phenyl-1,8-naphthyridine)gold(III), AuBr 3(N-N), has been prepared by reaction of KAuBr4 with the ligand in CHCl3/C2H5OH and was characterized by 1H NMR spectroscopy and X-ray diffraction. The molecular ...
-
(2010)Paper mulberry (Broussonetia papyrifera (L.) Vent.) was one of the most widely distributed crop species in prehistoric Oceania, occurring from continental East Asia to the Polynesian islands. Its broad distribution is ...
-
(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 ...
-
(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)Broussonetia papyrifera (L.) Vent. (Magnoliophyta: Urticales), or paper mulberry, is a species of Asian origin dispersed by humans throughout the Pacific. Our aim is to evaluate the genetic variability of this plant in ...
-
(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 ...
-
(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 ...
-
(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 ...
