RECONHECENDO-SE SEM-RELIGIÃO NAS PERIFERIAS DA CIDADE: LIBERDADE COMPARTILHADA COMO RESISTÊNCIA

Reconhecendo, a partir da constatação empírica, a multiplicidade de escolhas de crenças no Mundo e em particular na periferia urbana paulistana, reconhecemos, também, a emergência criativa de novas possibilidades de crer e não crer. Tal amplitude não apenas aponta para o crer (segundo as ofertas de um sem número de religiões) e o não crer (ateu e agnóstico), mas para uma escolha que poderia vir a ser silenciada e esquecida, neste binômio arcaico e obsoleto, quando alguém se dá à liberdade crer sem ter religião. Reconhecer interessadamente os sem-religião nas periferias urbanas paulistanas é dar-se conta das violências a que estes indivíduos estão submetidos: violência econômica, violência da cidadania (vulnerabilidade) e proveniente da armas (grupos x Estado). Tanto quanto a violência do esquecimento e silenciamento. A concomitância espaço-temporal dos sem-religião nas periferias, levou-nos buscar referências em teorias de secularização e de laicidade, e, a partir destas, traçar uma história do poder violento, cuja pretensão é a inelutabilidade, enquanto suas fissuras são abertas em espaços de resistências. A história da legitimação do poder que se quer único, soberano, de caráter universal, enquanto fragmenta a sociedade em indivíduos atomizados, fragilizando vínculos horizontais, e a dos surgimentos de resistências não violentas questionadoras da totalidade trágica, ao reconhecer a liberdade de ser com autonomia, enquanto se volta para a produção de partilha de bens comuns. Propomos reconhecer a igual liberdade de ser (expressa na crença da filiação divina) e de partilhar o bem comum em reconhecimentos mútuos (expressa pela ação social), uma expressão de resistência não violenta ao poder que requer a igual abdicação da liberdade pela via da fragmentação individualizante e submissão inquestionável à ordem totalizante. Os sem-religião nas periferias urbanas, nossos contemporâneos, partilhariam uma tal resistência, ao longo da história, com as melissas gregas, os profetas messiânicos hebreus, os hereges cristãos e os ateus modernos, cuja pretensão não é o poder, mas a partilha igual da liberdade e dos bens comuns. Estes laicos, de fato, seriam agentes de resistências de reconhecimento mútuos, em espaços de multiplicidade crescente, ao poder violento real na história.

República Federativa Evangélica: uma análise de gênero sobre a laicidade no Brasil a partir da atuação dos/as parlamentares evangélicos/as no Congresso Nacional no exercício da 54ª Legislatura São Bernardo do Campo

Essa pesquisa objetiva a análise da relação entre religião e política, em perspectiva de gênero considerando a atuação de parlamentares evangélicos/as na 54ª Legislatura (de 2011 a 2014) e a forma de intervenção desses atores no espaço político brasileiro quanto à promulgação de leis e ao desenvolvimento de políticas públicas que contemplem, dentre outras, a regulamentação do aborto, a criminalização da homofobia, a união estável entre pessoas do mesmo sexo e os desafios oriundos dessa posição para o Estado Brasileiro que se posiciona como laico. Ora, se laico remete à ideia de neutralidade estatal em matéria religiosa, legislar legitimado por determinados princípios fundamentados em doutrinas religiosas, pode sugerir a supressão da liberdade e da igualdade, o não reconhecimento da diversidade e da pluralidade e a ausência de limites entre os interesses públicos / coletivos e privados / particulares. Os procedimentos metodológicos para o desenvolvimento dessa pesquisa fundamentam-se na análise e interpretação bibliográfica visando estabelecer a relação entre religião e política, a conceituação, qualificação e tipificação do fenômeno da laicidade; levantamento documental; análise dos discursos de parlamentares evangélicos/as divulgados pela mídia, proferidos no plenário e adotados para embasar projetos de leis; pesquisa qualitativa com a realização de entrevistas e observações das posturas públicas adotadas pelos/as parlamentares integrantes da Frente Parlamentar Evangélica - FPE. Porquanto, os postulados das Ciências da Religião devidamente correlacionados com a interpretação do conjunto de dados obtidos no campo de pesquisa podem identificar o lugar do religioso na sociedade de forma interativa com as interfaces da laicidade visando aprofundar a compreensão sobre a democracia, sobre o lugar da religião nas sociedades contemporâneas e sobre os direitos difusos, coletivos e individuais das pessoas.

Rational engineering of a miniprotein that reproduces the core of the CD4 site interacting with HIV-1 envelope glycoprotein

Protein–protein interacting surfaces are usually large and intricate, making the rational design of small mimetics of these interfaces a daunting problem. On the basis of a structural similarity between the CDR2-like loop of CD4 and the β-hairpin region of a short scorpion toxin, scyllatoxin, we transferred the side chains of nine residues of CD4, central in the binding to HIV-1 envelope glycoprotein (gp120), to a structurally homologous region of the scorpion toxin scaffold. In competition experiments, the resulting 27-amino acid miniprotein inhibited binding of CD4 to gp120 with a 40 μM IC50. Structural analysis by NMR showed that both the backbone of the chimeric β-hairpin and the introduced side chains adopted conformations similar to those of the parent CD4. Systematic single mutations suggested that most CD4 residues from the CDR2-like loop were reproduced in the miniprotein, including the critical Phe-43. The structural and functional analysis performed suggested five additional mutations that, once incorporated in the miniprotein, increased its affinity for gp120 by 100-fold to an IC50 of 0.1–1.0 μM, depending on viral strains. The resulting mini-CD4 inhibited infection of CD4+ cells by different virus isolates. Thus, core regions of large protein–protein interfaces can be reproduced in miniprotein scaffolds, offering possibilities for the development of inhibitors of protein–protein interactions that may represent useful tools in biology and in drug discovery.

Retinoic acid induces proteasome-dependent degradation of retinoic acid receptor α (RARα) and oncogenic RARα fusion proteins

Analyzing the pathways by which retinoic acid (RA) induces promyelocytic leukemia/retinoic acid receptor α (PML/RARα) catabolism in acute promyelocytic leukemia (APL), we found that, in addition to caspase-mediated PML/RARα cleavage, RA triggers degradation of both PML/RARα and RARα. Similarly, in non-APL cells, RA directly targeted RARα and RARα fusions to the proteasome degradation pathway. Activation of either RARα or RXRα by specific agonists induced degradation of both proteins. Conversely, a mutation in RARα that abolishes heterodimer formation and DNA binding, blocked both RARα and RXRα degradation. Mutations in the RARα DNA-binding domain or AF-2 transcriptional activation region also impaired RARα catabolism. Hence, our results link transcriptional activation to receptor catabolism and suggest that transcriptional up-regulation of nuclear receptors by their ligands may be a feedback mechanism allowing sustained target-gene activation.

The long-range supraorganization of the bacterial photosynthetic unit: A key role for PufX

Bacterial photosynthesis relies on the interplay between light harvesting and electron transfer complexes, all of which are located within the intracytoplasmic membrane. These complexes capture and transfer solar energy, which is used to generate a proton gradient. In this study, we identify one of the factors that determines the organization of these complexes. We undertook a comparison of the organization of the light-harvesting complex 1 (LH1)/reaction center (RC) cores in the LH2− mutant of Rhodobacter sphaeroides in the presence or absence of the PufX protein. From polarized absorption spectra on oriented membranes, we conclude that PufX induces a specific orientation of the reaction center in the LH1 ring, as well as the formation of a long-range regular array of LH1-RC cores in the photosynthetic membrane. From our data, we have constructed a precise model of how the RC is positioned within the LH1 ring relative to the long (orientation) axis of the photosynthetic membrane.

Human mesothelial cells are unusually susceptible to simian virus 40-mediated transformation and asbestos cocarcinogenicity

Mesothelioma, a malignancy associated with asbestos, has been recently linked to simian virus 40 (SV40). We found that infection of human mesothelial cells by SV40 is very different from the semipermissive infection thought to be characteristic of human cells. Mesothelial cells are uniformly infected but not lysed by SV40, a mechanism related to p53, and undergo cell transformation at an extremely high rate. Exposure of mesothelial cells to asbestos complemented SV40 mutants in transformation. Our data provide a mechanistic explanation for the ability of SV40 to transform mesothelial cells preferentially and indicate that asbestos and SV40 may be cocarcinogens.

Retombées du cirque social (Cirque du Soleil) en contexte de réadaptation sur la participation sociale de jeunes adultes avec déficiences physiques en transition vers la vie active : étude qualitative

Introduction : Les adolescents avec déficiences physiques en transition vers la vie adulte éprouvent des difficultés à établir une participation sociale optimale. Cette étude explore les retombées d'un programme de cirque social sur la participation sociale de ces jeunes selon leur point de vue et celui de leurs parents. Méthode : Étude qualitative exploratoire d’orientation phénoménologique. Neuf personnes avec déficiences physiques, âgées de 18 et 25 ans, ont participé au programme pendant neuf mois. Données recueillies : perceptions de leur qualité de participation sociale à partir d’entrevues semi-structurées en pré, mi-temps et post-intervention avec les participants et un de leurs parents. Le guide d’entrevue validé est ancré sur le Modèle du développement humain- Processus de production du handicap - 2 (HDM-PPH2). L’enregistrement audio des entretiens a été transcrit en verbatim. Le contenu a été analysé avec le logiciel Nvivo 9 à travers une grille de codage préalablement validée (co-codage, codage-inverse). Résultats : Corpus de 54 entrevues. L’âge moyen des jeunes était de 20,0 ± 1,4 années et de 51 ± 3,6 années pour les parents. Selon tous, la participation sociale des jeunes adultes a été optimisée, surtout sur le plan de la communication, des déplacements, des relations interpersonnelles, des responsabilités et de la vie communautaire. La perception de soi et les habiletés sociales, également améliorées, ont favorisé une plus grande auto-efficacité. Conclusion : Cette étude soutient donc le potentiel du cirque social comme approche novatrice et probante en réadaptation physique pour cette population, et appuie la pertinence d’autres études rigoureuses mesurant les diverses retombées possibles et identifiées.
