O agente etiolgico da doena de Chagas, Trypanosoma cruzi, responsvel pela infeco de milhes de pessoas na Amrica Latina. No momento h apenas dois frmacos disponveis, o nifurtimox (5-nitrofurano), teve o uso descontinuado no Brasil, e o benzonidazol (2-nitroimidazole), embora ambos possuam aes limitadas, visto que dependem da fase da doena, das condies fisiolgicas do hospedeiro, da suscetibilidade e variabilidade gentica da cepa. Assim, a busca de novas molculas torna-se urgente e necessria, bem como a compreenso do mecanismo de resistncia aos frmacos tripanocidas. Alguns estudos relatam aumento na produo de enzimas que atuam na defesa celular, as quais, provavelmente, poderiam ser responsveis pela resistncia de certas cepas do parasita. Tais enzimas tm funes importantes na sobrevivncia e crescimento dos parasitas: superxido dismutase (SOD), uma metaloenzima que elimina radicais superxido ao convert-los em perxido de hidrognio e oxignio molecular; old yellow enzyme (OYE), que uma NADPH flavina oxidoredutase e pode estar envolvida na reduo de substncias tripanocidas; e, peroxiredoxina (Prx), que catalisa a reduo de perxidos. O objetivo deste projeto avaliar a suscetibilidade de diferentes cepas ao benzonidazol, clonar, sequenciar e expressar enzimas possivelmente envolvidas na resistncia a este frmaco e realizar anlises morfolgicas sero nos parasitos aps serem expostos substncia em questo. Futuramente os anticorpos policlonais obtidos a partir das protenas recombinantes de Prx, SOD e OYE sero empregados para avaliar o nvel de expresso das mesmas em parasitas tratados e no tratados com o benzonidazol.

This paper presents alternatives for waste energy recovery from the sewage of cities. Through a review of the literature it is observed that the technologies studied are usually turbines, microturbines, and engines adapted to the use of biogas. For project design analyzes the technologies found in some sewage treatment plants in Brazil and the world, compared with those found in the literature. With this study it can be concluded that the most used technologies are microturbines and motor generator sets, which are already implemented in some locations in the USA, Europe and even Brazil. It can also be concluded that the energy recovery of waste from sewage can enable design of wastewater treatment plants thereby contributing to improved quality of life

Protenas que apresentam atividades no ncleo e possuem sequncia de localizao nuclear (NLS) tem seu deslocamento dependente do heterodmero importina-/. A importina- (ImpA) responsvel pelo reconhecimento inicial do substrato a ser importado atravs da interao com os NLS. Os sinais so caracterizados por apresentar um ou mais grupos de aminocidos bsicos, denominados como sequncias monopartidas e bipartidas. O fungo Neurospora crassa vem sendo utilizado h mais de 70 anos como organismo modelo em estudos de expresso gnica, desenvolvimento e diferenciao celular, ritmo circadiano, defesa do genoma, bem como outros aspectos da biologia de eucariotos. A presena de um grande nmero de genes no genoma de N. crassa ainda com funes desconhecidas aponta este organismo como um promissor modelo para o estudo de novos mecanismos genticos e bioqumicos ainda no identificados. Considerando a importncia do metabolismo do glicognio para os organismos, o presente trabalho teve como objetivo o estudo estrutural de complexos de ImpA com peptdeos NLSs (NCM e NCB) de protenas envolvidas no metabolismo de glicognio do fungo N. crassa, utilizando tcnicas de cristalografia de protenas. Monocristais dos complexos ImpA-NCM e ImpA-NCB foram obtidos para a coleta dos dados de difrao de raios-X, resultando em dois conjuntos de dados 2,1 e 2,45 de resoluo, respectivamente. Aps elucidao da estrutura da ImpA, mapas de densidade eletrnica gerados revelaram uma densidade eletrnica no stio principal de reconhecimento de NLS da ImpA de ambas estruturas, possibilitando modelagem dos peptdeos. Em uma comparao do mapa de densidade eletrnica obtido de ambos complexos com um mapa de uma estrutura nativa de ImpA (70-529) coletada 2,0 de resoluo, a qual usualmente apresenta um peptdeo contaminante no sitio de ligao...

This paper aims to base the thesis that the varied currents of the post-modern thought, in so far as have recourse to relativism to a greater or lesser degree, contribute to the legitimation of the religious education in public schools and, in a broader aspect, the religion in the public spaces. The methodological resource used to demonstrate the link between post-modern thought and religious education is the analysis at the historical and dialectical materialism perspective of publications produced to increase teachers on this discipline that is, in compliance with the Constitution, optional for students and mandatory for public elementary schools. The subject of this analysis is the learning content and has as prime concern to highlight the discourse of legitimation recurrent in authors when it is explicit in itself and explicit when it does not. The religious education in public schools as object of study allows us to understand the relationship between the post-modern thought, with its hegemony space within the human sciences and contextualized in the neoliberal economic environment, and the learning to learn pedagogies currently hegemonic in the educational landscape. We intend to contribute to the legal debate on laity, the philosophical debate on post-modernism and especially to the debate on the pedagogical theories in the educational fundaments.

The present article aims to elaborate an objective analytical panel, initially from the 1920- 1930 when Luiz Igncio Romeiro de Anhaia Mello, cathedratic in the urban question, started to quote a series of authors and American plans as references to their reflections, mainly when the point was the verticalization or not at So Paulo City. From a broad bibliographic research with the systematization of the register from the debate between Anhaia Mello, this article intends to point out how the transposition of the urbanistic conceptions to the academic environment happened and, at the same time, the legal normatization of the So Paulo City that resulted in the creation of a draft of the regulations for use and occupation of the soil. The systematizations and analysis were based in a broad reading of the bibliography and documental sources that refer to the proposed theme. The books of the library of FAU-USP, specifically the one from SAGMACS Sociedade de Anlises Grficas e Mecanogrficas Aplicadas aos Complexos Sociais ( Society of Graphical Mechanical-Graphic Analysis Applied to Social Complexes) -, aiming to select papers and the collection of Anhaia Mellos family, so that a reconstruction of the intellectual and professional journey of the Urbanism Professor. The systematization of the collected data and posterior comparison with the bibliographical study was fundamental for the reconstruction of the reflection of Anhaia Mello about the ways of the urban streets and roads at Sao Paulo City should be lead to on the middle of the XX century having as a guideline the debate between Anhaia Mello very common on the 1950s for less important countries when dealing with the organization of the size of industrial metropolis. It was possible to identify the crystallization of one urbanistic proposal for the city: the from Anhaia Mello, that bet on the reversion of the metropolitan cycle by stopping the urban growth by the application of the theoretical conception of the garden city.
