    Evaluation of the antioxidant capacity of food samples: a chemical examination of the oxygen radical absorbance capacity assay
    (WILEY-BLACKWELL, 2018) Dorta Pérez, Eva; Fuentes Lemus, Eduardo Felipe; Speisky, Hernan; Lissi Gervaso, Eduardo A.; López Alarcón, Camilo Ignacio; Apak, Resat; Capanoglu, Esra; Shahidi, Fereidoon
    This chapter describes, from a critical point of view, the main in vitro methodologies employed to assess the antioxidant capacity (AC) of food samples. Considering the wide use of the oxygen radical absorbance capacity (ORAC) assay, it presents a chemical examination of this methodology. The methods for AC evaluation are based on different strategies; these include the use of colored and stable free radicals, evaluation of the capacity of antioxidants to reduce cupric or ferric ions, estimation of the ability of phenolic compounds (PC) to protect a target molecule exposed to a free radical source, and evaluation of the capacity of PC to form nanoparticles. When the antioxidant activity of a particular sample is evaluated, it is recommended to know the meanings and limitations of the assays being employed. In the case of the ORAC assay, the nature of the free radicals generated during the thermolysis of AAPH should also be considered.

    WOMEN AND WAR IN THE COLONIAL SPANISH AMERICAN EPIC Gendered Boundaries and Erotic Conquest
    (ROUTLEDGE, 2022) Carneiro Araujo Sarissa
    © 2022 WSEAS TRANSACTIONS on INFORMATION SCIENCE and APPLICATIONS. All rights reserved.From an iconic-textual perspective, I propose a reading of the «episodio de don Melón de la Huerta y de doña Endrina» from Libro de buen amor, in light of the concept of trompe l'oeil. In doing so, two fundamental aspects of medieval literature and the work of the Arcipreste de Hita will be addressed: the imagocentric configuration and the use of ambiguity as the result of a constructive will. I demonstrate how the deception associated with the love experience explains the identity mutation of the poetic self, which, in a game of confused tension between materiality and referentiality, will assume a new profile, of plastic nature, to the point of standing as the protagonist of a peculiar still life.
