(2012)Tara is a native species of Peru and is widely distributed in Latin America; its fruits (pods) have a high potential for medical, industrial and food uses. A supercritical tara polyphenol extract (STPE) was obtained from ...
-
(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 ...
-
(1988)1. 1. Intestinal clearances of flucloxacillin significantly decrease with the increase of pH, concomitantly with a decrease of the percent absorbed at 60 min. 2. 2. The apparent rate constants for unionized (Ku) and ionized ...
-
(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 ...

(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
