Das utopias globais, ruídos e recomposições: uma conversa sobre práticas de leitura e movimentos sociais
No full textPelo menos desde o Iluminismo a leitura ocupa um lugar nodal nos projetos emancipatórios abrigados dentro das tradições de esquerda. Mas, ao calor da revolução digital das últimas duas décadas, este espaço privilegiado experimentou profundas transformações sobre as quais talvez ainda não se tenha refletido o suficiente. Neste diálogo, Amador Fernández-Savater, Franco Ingrassia e Rodrigo Nunes, todos eles nascidos nos anos 70 e envolvidos ativamente em movimentos sociais das últimas duas décadas, destrincham alguns aspectos relativos às mudanças recentes nas relações entre as esquerdas, as redes sociais e as práticas de leitura. Desde suas cidades de residência no momento da entrevista –– Madrid, Rosário e Porto Alegre/Londres/Rio de Janeiro, respectivamente ––, mas em conexão com muitos outros lugares do mundo, os três participantes desta conversa têm estado desde os anos 90 envolvidos em numerosos espaços e iniciativas vinculadas ao ir e vir entre pensamento e movimentos sociais.

From global utopias, noise and recomposition: a conversation about reading practices and social movements
ABSTRACT
At least since the Enlightenment, reading stands on a nodal place in the emancipatory projects sheltered within leftist traditions. However, in the heat of the last two decades digital revolution, this privileged space has experienced deep transformations that may not yet have been sufficiently considered. In this dialog, Amador Fernández-Savater, Franco Ingrassia and Rodrigo Nunes, all of them were born in the 70’s and have been actively involved in the last two decades social movements, unravel some aspects of recent changes in left-wing relations, social networks and reading practices. From their home cities by the time of this interview – Madrid, Rosario and Porto Alegre/London/Rio de Janeiro, respectively –, but in connection with many other places in the world, the three participants of this conversation have been since the 90’s involved in many places and initiatives linked to the coming and going between thought and social movements.

Historia Argentina y vidas de santos, de Rodrigo Fresán: Hacia una nueva poética del género
No full textLa presente tesis lleva a cabo una evaluación estética de los dos primeros volúmenes de cuentos del escritor argentino Rodrigo Fresán, los cuales constituyen no solo la semilla de su proyecto creador — que encarna una ruptura con el viejo paradigma del cuento moderno — , sino que, además , son pieza clave para identificar su toma de posición (Bourdieu) . Así, esta disertación se enfoca en el contexto sociocultural en el cual el autor produce su obra y en las relaciones que establece con las formas clásicas del cuento. A lo largo del proceso de investigación, puse en diálogo distintas perspectivas teóricas y criticas del género cuento y diferentes marcos históricos e ideológicos que han acompañado su génesis y evolución. Finalmente, pongo especial atención a la toma de posición del autor en el campo literario y cultural latinoamericano, puesto que es fundamental su comprensión a la hora de trazar una estética de la obra del escritor y del género.Abstract: The present thesis carries out an esthetic evaluation of the two first volumes of short stories from the Argentinian writer Rodrigo Fresan, whi ch not only is th e seed of his created project — which means a rupture with the old paradigma from the modern short story — but is also a key part in identifying it's p osition - taking ( Bourdieu). This is how this discourse is focused in the social cultural context in which the author produces his work and in the relations which are established with the classical forms of the sh ort story. Through out th e process of the investigation , I put both theories in confrontation with one another with their different theoretical and critics perspectives of the short story genr e and different historical and ideological moments that have aco mpanied it's genisis and evolution . I finaly pay especial attent ion to the position - tak ing by the author in the Latin American literary and cultural field , as it's understanding is fundamental in the moment of drawing a esthetic line from the work of the w riter and gen r e .Maestrí

No full textModulation of CD40 ligand (CD40L) expression by polypyrimidine tract-binding protein
No full textCD40 ligand (CD40L or CD154) is a protein expressed on activated CD4+ T cells, which is crucial for antibody-dependent and cell-mediated immunity. The expression of CD40L is tightly regulated at multiple levels throughout a time course of T cell activation. At the post-transcriptional level the CD40L message is rapidly degraded at early time points of activation followed by a significant increase in message stability at later times of activation (24-48 hr). Previous work from our lab revealed that a cytoplasmic polypyrimidine tract binding protein (PTB)-containing-complex binds to the CD40L 3'UTR at later times of T cell activation. To understand the direct relationship between PTB and CD40L mRNA stability and subsequently CD40L expression, we used viral RNA interference against PTB and scrambled shRNA (Control) sequence in model CD40L mRNA stability T cell line, Jurkat/D1.1. Downregulation of PTB resulted in dramatic decrease in half-life of the CD40L mRNA. The downregulation of PTB did not significantly change the percentage of CD40L+ cells, but caused an approximate 2-fold decrease in the mean fluorescence (MFI) of CD40L. Cellular fractionation of CD40L mRNA from shCTRL- and shPTB-infected cells revealed a novel role for nuclear PTB in retaining the CD40L mRNA in the nucleus. In addition, cytoplasmic PTB is important for optimal association of CD40L message with translating polysomes. Analysis of PTB cellular distribution during a time course of CD4+ T cell activation revealed cytoplasmic and nuclear localization in all resting and activated cells. However, there was an increase in cytoplasmic PTB expression at late times of activation. Binding studies revealed that CD40L mRNA is bound by nuclear PTB at all times of activation indicating that the requirements for binding of CD40L message by nuclear versus cytoplasmic PTB is highly distinct. Finally, the binding of CD40L message corresponded to a post-translational modification of cytoplasmic PTB that appears to correlate with a change in phosphorylation status of PTB. Confocal microscopy analysis of CD4+ T cells with activation-induced CD40L mRNA stability revealed co-localization of PTB and CD40L mRNA at distinct foci, suggesting a role of PTB in the localization of the stable CD40L message during T cell activation.M.S.Includes abstractIncludes bibliographical referencesby Rodrigo A.
