(Springer New York LLC, 2017)© 2016, American Association of Pharmaceutical Scientists. Peptides and proteins represent a promissory group of molecules used by the pharmaceutical industry for drug therapy with great potential for development. However, ...
-
(1987)A complete description of the rotational isomerism of monothioformic acid is presented. Ab initio results concerning the barrier heights and the energy difference between the stable isomers are in good agreement with the ...
-
(BioMed Central Ltd., 2014)© 2014 Gutierrez et al.; licensee BioMed Central Ltd. Background: Cardiac hypertrophy is characterized by alterations in both cardiac bioenergetics and insulin sensitivity. Insulin promotes glucose uptake by cardiomyocytes ...
-
(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 ...
-
(1995)This work reports a comparative study of the catalytic behaviour for a series of metallocenes derived from Ti, Zr, Hf and Nb, which after activation with methylaluminoxane can polymerize ethylene. Results show that the Zr ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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, ...
-
(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 ...
-
(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 ...
