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.

(In)VERSÕES POLÍTICO-ESCATOLÓGICAS NO PENTECOSTALISMO BRASILEIRO Uma análise da posição e ação política das Assembleias de Deus de 1930-1945 e 1978-1988 a partir do jornal Mensageiro da Paz

A presente pesquisa analisou a posição e ação política nas Assembleias de Deus do Brasil nos períodos 1930-1945 e 1978-1988. Defendemos a tese de que desde 1930 há no interior do pentecostalismo brasileiro posições e intervenções no mundo da política. Tanto no período de 1930-1945 como o de 1978-1988 nossas análises serão realizadas a partir das temporalidades discutidas por Giorgio Agamben: chronos, aiôn e kairos. No que diz respeito ao primeiro período 1930-1945, as pesquisas quase sempre vinculam o discurso escatológico do pentecostalismo a processos de alienação e não envolvimento com a política partidária. Entretanto, acredita-se que as narrativas escatológicas não foram causa de certo afastamento da esfera pública brasileira, mas sim efeito de processos de exclusão aos quais homens e mulheres de pertença pentecostal estiveram circunscritos. Doutrinas como a escatologia e a pneumatologia foram potencializadoras de processos que aqui denominamos de biopotência. Já no segundo período, de 1978-1988, a posição e a ação política que predominaram no pentecostalismo estiveram relacionadas com a biopolítica. Chamamos de capítulo intermedário ou de transição o período correspondente às datas 1946-1977. Nele descreveremos e analisaremos personalidades pentecostais de destaque no campo da política brasileira. Metodologicamente, fizemos nossa análise a partir de artigos publicados no órgão oficial de comunicação da denominação religiosa em questão, o jornal Mensageiro da Paz. Esse periódico circula desde 1930. Além dos artigos, destacamos também as autoras e os autores, todas elas e todos eles figuras de destaque no assembleianismo. Ao longo da pesquisa questionamos a ideia do apoliticismo pentecostal. Defendemos a tese de que desde 1930, que é o início de nossa pesquisa, há posição e ação política nas Assembleias de Deus. Como resultado disso, questionamos a ideia do apoliticismo pentecostal. Nossa hipótese é de que no período 1930-1945 o pentecostalismo foi um polo de biopotência. Se a biopolítica é o poder sobre a vida, a biopotência é o poder da vida. Doutrinas como a escatologia e pneumatologia contribuíram para que nos espaços marginais onde se reuniam os pentecostais fossem criados novos modelos de sociabilidade e de cooperação; eram também espaços de criação de outras narrativas e de crítica a modelos hegemônicos e excludentes. O pentecostalismo foi um movimento que promoveu a dignidade humana de sujeitos subalternos.

Expression of hepatocyte nuclear factor 6 in rat liver is sex-dependent and regulated by growth hormone

Growth hormone (GH) binding to its receptor modulates gene transcription by influencing the amount or activity of transcription factors. In the rat, GH exerts sexually dimorphic effects on liver gene transcription through its pattern of secretion which is intermittent in males and continuous in females. The expression of the CYP2C12 gene coding for the female-specific cytochrome P450 2C12 protein is dependent on the continuous exposure to GH. To identify the transcription factor(s) that mediate(s) this sex-dependent GH effect, we studied the interactions of the CYP2C12 promoter with liver nuclear proteins obtained from male and female rats and from hypophysectomized animals treated or not by continuous GH infusion. GH treatment induced the binding of a protein that we identified as hepatocyte nuclear factor (HNF) 6, the prototype of a novel class of homeodomain transcription factors. HNF-6 competed with HNF-3 for binding to the same site in the CYP2C12 promoter. This HNF-6/HNF-3 binding site conveyed both HNF-6- and HNF-3-stimulated transcription of a reporter gene construct in transient cotransfection experiments. Electrophoretic mobility shift assays showed more HNF-6 DNA-binding activity in female than in male liver nuclear extracts. Liver HNF-6 mRNA was barely detectable in the hypophysectomized rats and was restored to normal levels by GH treatment. This work provides an example of a homeodomain-containing transcription factor that is GH-regulated and also reports on the hormonal regulation of HNF-6.

Three-dimensional domain swapping in p13suc1 occurs in the unfolded state and is controlled by conserved proline residues

p13suc1 has two native states, a monomer and a domain-swapped dimer. We show that their folding pathways are connected by the denatured state, which introduces a kinetic barrier between monomer and dimer under native conditions. The barrier is lowered under conditions that speed up unfolding, thereby allowing, to our knowledge for the first time, a quantitative dissection of the energetics of domain swapping. The monomer–dimer equilibrium is controlled by two conserved prolines in the hinge loop that connects the exchanging domains. These two residues exploit backbone strain to specifically direct dimer formation while preventing higher-order oligomerization. Thus, the loop acts as a loaded molecular spring that releases tension in the monomer by adopting its alternative conformation in the dimer. There is an excellent correlation between domain swapping and aggregation, suggesting they share a common mechanism. These insights have allowed us to redesign the domain-swapping propensity of suc1 from a fully monomeric to a fully dimeric protein.

Electric-field-induced Schiff-base deprotonation in D85N mutant bacteriorhodopsin.

The application of an external electric field to dry films of Asp-85-->Asn mutant bacteriorhodopsin causes deprotonation of the Schiff base, resulting in a shift of the optical absorption maximum from 600 nm to 400 nm. This is in marked contrast to the case of wild-type bacteriorhodopsin films, in which electric fields produce a red-shifted product whose optical properties are similar to those of the acid-blue form of the protein. This difference is due to the much weaker binding of the Schiff-base proton in the mutant protein, as indicated by its low pK of approximately 9, as compared with the value pK approximately 13 in the wild type. Other bacteriorhodopsins with lowered Schiff-base pK values should also exhibit a field-induced shift in the protonation equilibrium of the Schiff base. We propose mechanisms to account for these observations.

Hepatocyte nuclear factor 6, a transcription factor that contains a novel type of homeodomain and a single cut domain.

Tissue-specific transcription is regulated in part by cell type-restricted proteins that bind to defined sequences in target genes. The DNA-binding domain of these proteins is often evolutionarily conserved. On this basis, liver-enriched transcription factors were classified into five families. We describe here the mammalian prototype of a sixth family, which we therefore call hepatocyte nuclear factor 6 (HNF-6). It activates the promoter of a gene involved in the control of glucose metabolism. HNF-6 contains two different DNA-binding domains. One of these corresponds to a novel type of homeodomain. The other is homologous to the Drosophila cut domain. A similar bipartite sequence is coded by the genome of Caenorhabditis elegans.

Translation initiation of ornithine decarboxylase and nucleocytoplasmic transport of cyclin D1 mRNA are increased in cells overexpressing eukaryotic initiation factor 4E.

The structure of m7GpppN (where N is any nucleotide), termed cap, is present at the 5' end of all eukaryotic cellular mRNAs (except organellar). The eukaryotic initiation factor 4E (eIF-4E) binds to the cap and facilitates the formation of translation initiation complexes. eIF-4E is implicated in control of cell growth, as its overexpression causes malignant transformation of rodent cells and deregulates HeLa cell growth. It was suggested that overexpression of eIF-4E results in the enhanced translation of poorly translated mRNAs that encode growth-promoting proteins. Indeed, enhanced expression of several proteins, including cyclin D1 and ornithine decarboxylase (ODC), was documented in eIF-4E-overexpressing NTH 3T3 cells. However, the mechanism underlying this increase has not been elucidated. Here, we studied the mode by which eIF-4E increases the expression of cyclin D1 and ODC. We show that the increase in the amount of cyclin D1 and ODC is directly proportional to the degree of eIF-4E overexpression. Two mechanisms, which are not mutually exclusive, are responsible for the increase. In eIF-4E-overexpressing cells the rate of translation initiation of ODC mRNA was increased inasmuch as the mRNA sedimented with heavier polysomes. For cyclin D1 mRNA, translation initiation was not increased, but rather its amount in the cytoplasm increased, without a significant increase in total mRNA. Whereas, in the parental NIH 3T3 cell line, a large proportion of the cyclin D1 mRNA was confined to the nucleus, in eIF-4E-overexpressing cells the vast majority of the mRNA was present in the cytoplasm. These results indicate that eIF-4E affects directly or indirectly mRNA nucleocytoplasmic transport, in addition to its role in translation initiation.

Identification of the overtone of the Fe-CO stretching mode in heme proteins: a probe of the heme active site.

Two CO-isotope sensitive lines have been detected in the overtone region of the resonance Raman spectra of CO-bound hemeproteins. One line is assigned as the overtone of the Fe-CO stretching mode and is located in the 1000- to 1070-cm-1 region. The other line is found in the 1180- to 1210-cm-1 region and is assigned as a combination between a porphyrin mode, nu 7, and the Fe-CO stretching mode. The high intensities of these lines, which in the terminal oxidase class of proteins are of the same order as those of the fundamental stretching mode, indicate that the mechanism of enhancement for modes involving the Fe-CO moiety is different from that for the modes of the porphyrin macrocycle and call for reexamination of Raman theory of porphyrins as applied to axial ligands. The anharmonicity of the electronic potential function was evaluated, revealing that in the terminal oxidases the anharmonicity is greater than in the other heme proteins that were examined, suggesting a distinctive interaction of the bound CO with its distal environment in this family. Furthermore, the anharmonicity correlates with the frequency of the C-O stretching mode, demonstrating that both of these parameters are sensitive to the Fe-CO bond energy. The overtone and combination lines involving the bound CO promise to be additional probes of heme protein structural properties.

"Conscience is the best casuist" (manuscript essay), 1799 September 10

Three-page handwritten essay in English by Buckminster on the subject of conscience told through a story about a young man named Henry who saves a starving woman. The essay begins, "The disquisitions of the metaphysical world upon the origin and nature of conscience are quite unnecessary to a complete comprehension of the significancy of our motto." The essay is titled with a quote from Jean-Jacques Rousseau's Emile, Or on Education.
