(Royal Society of Chemistry, 2015)M′0.2Mn 0.8PS3·0.25H2O materials are obtained by a mild microwave assisted reaction (M′ = CoII, NiII, CuII, ZnII), which permitted us to obtain the first copper(ii) bimetallic phase. All these materials have a lower energy ...
-
(Springer New York LLC, 2017)The potential activity of mango by-products to inhibit the peroxyl radical-mediated oxidation of tryptophan residues (Trp) of myofibrillar proteins (MP) was studied. Extracts of seeds, peels and pulps were studied in terms ...
-
(1985)We have analyzed the dependence of the serotonin receptor binding affinity on the electronic and steric reactivity indexes for a group of 5‐substituted tryptamines. The approaches employed are a new nonempirical Quantitative ...
-
(Universidad de Santiago de Chile, 2016)© 2016 Universidad de Santiago de Chile. All rights reserved. The aim of this study was to assess the differences in qualitative-quantitative composition of triterpenoids and total phenolic contents, together with ...
-
(1968)The free radicals induced by gamma radiation in deaerated aqueous solutions of 2′‐3′ uridylic acid at 77°K have been studied by electron spin resonance techniques. The annealing at 193°K of the OH radical trapped at 77°K ...
-
(1991)A preconcentration method based on the adsorption on activated carbon of a binary complex of copper(I) with 2,2’-biquinoline, and subsequent polarographic determination of microamounts of copper has been developed. The ...
-
(1993)A sensor for the determination of cadmium based on retention of the Cdl4″ complex on a QAE Sephadex resin located in the flow-cell of a conventional photometric detector and on subsequent complex displacement reaction with ...
-
(Dental Investigations Society, 2016)© 2016 European Journal of Dentistry | Published by Wolters Kluwer-Medknow. Objective: Although sucrose is considered the most cariogenic carbohydrate in the human diet, the question of how many exposures are needed to ...
-
(Springer New York LLC, 2017)© 2016, American Association of Pharmaceutical Scientists. The development of an appropriate dosage form for pediatric patients needs to take into account several aspects, since adult drug biodistribution differs from that ...
-
(Elsevier Ltd, 2016)© 2015, Elsevier Ltd. All rights reserved. Haematococcus pluvialis is a natural source of astaxanthin (AX). However, AX loses its natural protection when extracted from this microalga. In this study, a supercritical fluid ...
-
(1995)Electrochemical reduction of Ketanserin was studied at different pH and concentrations using polarography and cyclic voltammetry. Ketanserin exhibits two differential pulse polarographic peaks at the dropping mercury ...
-
(Springer New York LLC, 2017)© 2016, American Association of Pharmaceutical Scientists.The main route of administration for drug products is the oral route, yet biologics are initially developed as injectables due to their limited stability through ...
-
(1991)A simple device for an efficient waste water treatment is described. The procedure uses a massive microalga culture as a source of OH-, which increases the pH of the medium killing the bacterial population. In the device ...
-
(1982)Enzymatic hydrolysis of skim milk lactose and proteins was investigated in a batch reactor; the final aim is to produce a predigested dietary product. The use of yeast β‐galactosidase, a vegetable protease, a fungal protease, ...
-
(American Chemical Society, 2001)Continuum solvent effect on the electrophilicity index recently proposed by Parr and co-workers (Parr, R. G.; von Szentpaly, L.; Liu, S. J. Am. Chem. Soc. 1999, 121, 1922) is discussed in detail. Solvent effect is introduced ...
-
(Sociedade Brasileira de Quimica, 2016)Glycolipids are biomolecules composed of a lipid chain (lipophilic) and a monosaccharide or oligosaccharide as hydrophilic group. Their chemical structure and biological role make them undoubtedly good candidates for a ...
-
(Elsevier Ltd, 2010)The voltammetric reduction of 1-methyl- and 1-H- 4-nitroimidazole derivatives was studied in different protic and aprotic media to investigate the influence of the N-1 substitution in the mechanism of reduction, the ...
-
(Springer Verlag, 2016)Phenolic compounds are generated by the secondary metabolism of plants and have been associated with antibacterial properties. Among bacteria affecting human health, Helicobacter pylori has been associated with gastric ...
-
(1973)The radioprotective ability of L-tryptophan, tryptamine, 3-indoleacetic and indole (10−4 m), on UV and gamma irradiated DNA (10−4 m) is studied. UV radioprotection is accomplished in the following order of efficiency: ...
-
(1993)EPR has been used to investigate the radicals postulated as intermediates in the intramolecular electron transfer and dehalogenation of p-nitrobenzyl bromide (p-NBBr) in DMSO and DMFA at room temperature. The electrochemical ...
