(Pontificia Universidad Católica de Chile, 2017)The production of high quality natural Antioxidants from olive pruning wood extracts and their application to prevent the oxidation of vegetable oils were evaluated. The production of antioxidants from branches of olive ...
-
(2012)Rifampicin, a poorly soluble drug, has great importance in therapeutics as it is the main drug used to treat tuberculosis. The characterization of its permeability and the factors that influence it represent an important ...
-
(Verlag der Zeitschrift fur Naturforschung, 2004)The effect of different photon flux densities (PFD) and temperatures on the relative growth rate (RGR) and the concentration of three halogenated monoterpenes in samples of Plocamium cartilagineum L.( Dixon), a marine alga ...
-
(Ministerio de Educación Superior, 2003)Seven types of chemical sensors based on polymeric liquid membranes for determination of nitrate ion have been prepared by using 3-nitro-o-xylene (NOX), tri-butyphosphate (TBP), bis-(2-ethylhexyl)sebacate (DOS), ...
-
(MDPI, 2020)The effect of a prior chilling period and an alga extract packaging on the quality of a canned underutilised mackerel species (Scomber colias) was investigated. For this different chilling times (0, 4 and 9 days) were taken ...
-
(Springer, 2020)The algaeDurvillaea antarctica(cochayuyo) is the most popular edible seaweed in Chile and shows extensive variability at the marketplace. The objective of this study was to characterize the sample ofD. antarcticaand modify ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2000-01)We have tested several chemical modifiers to investigate which amino acid residues, present in the primary structure of the ecto-apyrase, could be involved in catalysis. Synaptosomes from cerebral cortex of rats were ...
-
(1986)The effect of roasting lupin seeds (Lupinus albus cv Multolupa) for 10, 20, 30, and 40 min at 80–90°C was studied. Raw lupin was shown to be markedly deficient in the S‐amino acids. These were not affected by roasting for ...
-
(2006)The effect of the addition of rosa mosqueta husk extract (RME) on thermal oxidation of nontreated (HZO) and treated (THZO) Chilean hazelnut seed oil was evaluated at 180°C for 18 h. THZO to which was added 339 mg/kg of ...
-
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2009-12)In the search of new therapeutic tools for the treatment of American Trypanosomiasis, the largest parasitic disease burden in the American continent, three series of novel ruthenium complexes of the formula [RuCl2(HL)(2)], ...
-
(American Society of Agronomy, 1971)A volcanic ash-derived soil was incubated uo to 93 days with different amounts of seaweed. P was then extracted using an anion exchange resin method, and it was found that extractable P increased with increasing amounts ...
-
(American Society of Agronomy, 1968)The objective of the present investigation was to study changes in levels of phosphorus and nitrogen in soils supplemented with dry, ground seaweeed, KNO3, and KH2PO4. After intervals of 21, 42, 76 and 105 days, phosphorus, ...
