Protein tyrosine nitration and thiol oxidation by peroxynitrite-strategies to prevent these oxidative modifications.

2013

The reaction product of nitric oxide and superoxide, peroxynitrite, is a potent biological oxidant. The most important oxidative protein modifications described for peroxynitrite are cysteine-thiol oxidation and tyrosine nitration. We have previously demonstrated that intrinsic heme-thiolate (P450)-dependent enzymatic catalysis increases the nitration of tyrosine 430 in prostacyclin synthase and results in loss of activity which contributes to endothelial dysfunction. We here report the sensitive peroxynitrite-dependent nitration of an over-expressed and partially purified human prostacyclin synthase (3.3 μM) with an EC50 value of 5 μM. Microsomal thiols in these preparations effectively co…

Cuerpos de energía: Formas alternativas de ser-en-el-mundo

2020

Based on an ethnographic approach, this paper explores how members of a new age spiritual movement known as ?Llave Mariana? (LLM) build and experience their bodies. At the same time, it develops a thick description of their ritual practices and later it analyzes, delving fundamentally into the phenomenological perspective, how these members shape and transform their forms of self-perception, experience, and representation of others and the environment. Finally, it considers the implications these spiritual practices have in the search and consolidation of alternative ways of being-in-the-world

Violência, evasão e exclusão na educação superior

2019

The present text focuses on a relationship between higher education, institutional and symbolic violence and exclusion, practicing as a challenge based on reflections on the existence of evasion in Brazilian university. Ignoring the educational institution as a direct responsible for these things, this text considers that a logic in University organization and operation helps to enlarge inequalities that provide the mechanisms of evasion; at the same time, it presents itself as a space of reference and a struggle against social inequalities and violence. On a provisional basis, the text stands out that: depending on the execution of educational procedures and practices undertaken by the ins…

Gas-liquid-solid operation of a Long Draft Tube Self-ingesting Reactor (LDTSR)

2008

Gas-liquid stirred vessels are widely employed to carry out chemical reactions involving a gas reagent and a liquid phase. The usual way for introducing the gas stream into the liquid phase is through suitable distributors placed below the impeller. An interesting alternative is that of using “self ingesting” vessels where the headspace gas phase is injected and dispersed into the vessel through suitable surface vortices. In this work the performance of a Long Draft Tube Self-ingesting Reactor dealing with gas-liquid-solid systems, is investigated. Preliminary experimental results on the effectiveness of this contactor for particle suspension and gas-liquid mass transfer performance in pres…

Les tecnologies de la informació i la comunicació a l'àrea de Llengua en Educació Primària

2015

Estem davant d’un moment històric en què la construcció de la societat i la cultura es fa des d’un paradigma sociocontructivista. Més si cap amb la irrupció de les Tecnologies de la Informació i la Comunicació (TIC) que permeten arribar, de manera immediata, la informació i el coneixement a qualsevol racó del món i persona. Aquesta ferramenta amb un impacte tan gran a nivell global i col·lectiu, és clar que també ho és a nivell individual. Però, qui s’ha parat a atendre aquesta qüestió des de la base del funcionament del món que és l’Educació? Mitjançant el TFG que es presenta a continuació, recorrerem històricament l’evolució de les TIC, així com les influències d’aquestes dintre de l’àmbi…

Sense experience and differentiation : Husserl on bodily awareness

2023

This article outlines the basic ingredients of Husserl’s theory of bodily awareness. It first analyses the concepts of hyletic and kinesthetic sensibility, and illustrates the interwovenness and equiprimordiality of Me and not-Me in Husserl’s account. Second, it shows how the concept of the lived body emerges from this complex sensible foundation. Thirdly, it argues that, as the area of intersection between the Me and the not-Me, bodily awareness is the initial locus of differentiation between Me and not-Me: an area where the experiential distinction between the Me and the not-Me is constantly negotiated. peerReviewed
