The synthesis of a water-soluble derivative of rutin as an antiradical agent

The purpose of this study was to synthesize a water-soluble derivative of rutin (compound 2) by introducing carboxylate groups on rutin's sugar moiety. The rutin derivative showed an almost 100-fold solubility increase in water. The antiradical capacity of compound 2 was evaluated using the luminol/AAPH system, and the derivative's activity was 1.5 times greater than that of Trolox®. Despite the derivative's high solubility in water (log P = -1.13), lipid peroxidation of brain homogenate membranes was very efficiently inhibited (inhibition values were only 19% lower than the inhibition values of rutin)

A Council of Europe perspective on the European Union: Crucial and complex cooperation

The article addresses the institutional role of the EU in the Council of Europe, with particular emphasis on EU participation in Council of Europe treaties and EU accession to the ECHR. While recognising the joint effort to achieve greater unity in the region of Europe through respect for the shared core values of pluralist democracy, human rights and the rule of law, the concerns raised by non-Member States of the EU about the impact of EU law and policies on the Council of Europe’s standards are examined. It is argued that the Council of Europe and the EU have a shared responsibility for upholding the effectiveness of their respective frameworks and ensuring that any overlapping competences do not create conflict. This is particularly evident when it comes to the European system for the protection of fundamental rights, which is characterised by overlapping standards and procedures. The existing cooperation between the Council of Europe and the EU should be strengthened through a more rational, rules-based approach. In particular, it is suggested that the two systems should jointly agree on a series of basic principles on the treaty-making process, providing for horizontal application by the introduction of specific rules on, for example, voting and speaking rights of the EU, the sharing of reporting obligations between the EU and its Member States under Council of Europe monitoring mechanisms, and financial arrangements. The EU’s participation and financial contribution to monitoring follow-up should always be considered on a case-by-case basis, taking into account the specificities of each mechanism

Historia y valor. Lo económico desde la crítica postoniana al marxismo tradicional

En este artículo buscamos presentar la necesidad de una conceptualización más profunda de lo económico como condición de posibilidad de una crítica marxista. Para ello nos centraremos en la crítica de M. Postone al marxismo tradicional —cuyo representante en este caso es G. Markus—, para luego dar cuenta de las limitaciones de dicha crítica. Fundamentalmente, sostendremos, a partir de la argumentación, que la crítica postoniana constituye un momento exclusivamente negativo al postular la abolición del valor como objetivo de la praxis, sin construir una legalidad diferenciada de lo económico que la reemplace

A crise atual do trabalho e seus reflexos na comunidade israelita de Belo Horizonte: o projeto AVIV

The present dissertation is inserted in the field of Work Psychosociology, in the Masters Program of Social Psychology, from the UFMG. Its main theme is the actual work crisis. This study has a qualitative approach and its aim is to comprehend the psychosocialreality involved in the search for work/job, from the point of view or the worker in the jobless condition or from the perspective of a social agent implied with the issue. Its starting point is the effort of the AVIV Project in answering the workers demand for work/job in the Israeli Community of Belo Horizonte, due to the actual work crisis. Theoretically, this study was based on the French oriented Psychosociology, especially onEugène Enriquezs work, The Organization in Analysis, that considers the various dimensions involved in the social phenomenon and, therefore, extend the knowledge in this field of study. In trying to understand the reality involved in the search for work/job for the AVIV Project, the complex dimension of the actual work crisis became evident and its social and personal implications were enlarged, and, at the same time, this allowed to redefine the project, based on the comprehension of its limitations in front of these processes. The analysis of the Israeli Community of Belo Horizonte, through the AVIV project, points out, yet, positive processes of changing, by reestablishing the community links and also by the articulation with the historical dimension that can be found considering the work category. Others important themes related to the research work carried out, such as the actual international work crisis, the subject in the contemporary context and the question of identity were also developed.(Polakiewicz, Eleusa Mizrahy.

Brasil.)Esta dissertação se insere no campo da Psicossociologia do Trabalho, disciplina integrante do Mestrado de Psicologia Social da UFMG, e tem como tema a crise atual do trabalho. De caráter qualitativo, o estudo visa a compreender a realidade psicossocial envolvida naprocura de trabalho/emprego, seja como trabalhador na condição de desemprego, seja como agente social implicado nessa questão. Toma-se como ponto de partida o empenho do projeto Aviv em responder à demanda de trabalhadores por trabalho/emprego na comunidade israelita de Belo Horizonte, diante da atual crise do trabalho. Teoricamente, este estudo baseou-se na Psicossociologia de orientação francesa, através da obra de Eugène Enriquez, Organização em análise, para considerar as várias dimensões dos fenômenos sociais e, assim, ampliar os conhecimentos nesse campo de estudo. Ao se procurar compreender a realidade envolvida na busca por trabalho/emprego, deparou-se, no projeto Aviv, com a complexidade da crise atual do trabalho em seus desdobramentos sociais e pessoais e, ao mesmo tempo, redimensionou-se o próprio projeto, pela visão de suas limitações e possibilidades frente a esses processos.A análise da comunidade israelita de Belo Horizonte através do projeto Aviv assinala, ainda, processos positivos de mudança, tanto pelo restabelecimento de vínculos comunitários, como pela articulação com a dimensão histórica da categoria trabalho. Temas pertinentes à pesquisa foram desenvolvidos, tais como a crise atual do trabalho, o sujeito no contexto contemporâneo e a questão da identidade, entre outros
