In this way, an analysis of the legal provisions of the two countries, to the end see if both aim at the preservation of the company, respectively, Law Recovery and Bankruptcy no. 11.101/05, in Code de Commerce - French commercial code, chapter Des difficultés des enterprises.

A lei e a força no regime militar brasileiro: da proscrição da frente ampla à edição do Ato Institucional n. 5

This article analyses the Brazilian political process in the period between the beginning of the government of general Arthur da Costa e Silva in March 15, 1967 and the edition of the Institutional Act No. 5 (December 13, 1968). Through the analysis of the key moments in this context, seeks to qualify the actions of the main political players in terms of their goals and strategies and assess the impact that they had on the production of authoritarian legislation.

Análise espacial de óbitos por acidentes de trânsito, antes e após a Lei Seca, nas microrregiões do estado de São Paulo

OBJETIVO: Identificar aglomerados espaciais de microrregiões segundo taxas de óbito por acidentes de trânsito, no Estado de São Paulo, 1 ano antes e 1 ano após a Lei Seca. MÉTODOS: Estudo ecológico e exploratório, no período de 2007 e 2009, em 63 microrregiões do Estado de SP, Brasil. Utilizaram-se ferramentas de geoprocessamento com dados do DATASUS; analisando óbitos decorrentes de acidentes de trânsito em taxas por 100 mil habitantes, construindo coropletes. Nova estatística foi obtida subtraindo-se a taxa de 2009 de 2007, observando regiões de melhora ou piora. RESULTADOS: Em 2007, ocorreram 5.204 óbitos, com média de 83 óbitos/microrregião, variando entre 1 e 1.440. Já 2009 obteve 5.065 óbitos com a média de 80 óbitos/microrregião, variando entre 1 e 1.453. O coeficiente de Moran em 2007 foi I = 0,09 (p = 0,04) com correlação espacial positiva e 2009 obteve I = 0,04 (p = 0,16), sem correlação. A diferença entre as taxas obteve I = 0,23 (p = 0, 007), indicando associação espacial. Em 2007, Presidente Prudente, Rio Claro, Campinas, Bragança Paulista, Osasco e São Paulo tiveram altas taxas de óbito. Dessas regiões citadas, somente Osasco não se destacou em 2009. Ribeirão Preto, Ourinhos e Avaré obtiveram piora em 2009. A diferença entre as taxas de 2009 e 2007 mostrou que Amparo, Bragança Paulista e Campinas tiveram melhora, e Presidente Prudente e Ourinhos apresentaram piora. CONCLUSÃO: Foi possível identificar os locais com as maiores taxas de mortalidade, apontando locais onde as ações de fiscalização devem ser revisadas.

Human TOP1 residues implicated in species specificity of HIV-1 infection are required for interaction with BTBD2, and RNAi of BTBD2 in old world monkey and human cells increases permissiveness to HIV-1 infection

Host determinants of HIV-1 viral tropism include factors from producer cells that affect the efficiency of productive infection and factors in target cells that block infection after viral entry. TRIM5 restricts HIV-1 infection at an early post-entry step through a mechanism associated with rapid disassembly of the retroviral capsid. Topoisomerase I (TOP1) appears to play a role in HIV-1 viral tropism by incorporating into or otherwise modulating virions affecting the efficiency of a post-entry step, as the expression of human TOP1 in African Green Monkey (AGM) virion-producing cells increased the infectivity of progeny virions by five-fold. This infectivity enhancement required human TOP1 residues 236 and 237 as their replacement with the AGM counterpart residues abolished the infectivity enhancement. Our previous studies showed that TOP1 interacts with BTBD1 and BTBD2, two proteins which co-localize with the TRIM5 splice variant TRIM5 in cytoplasmic bodies. Because BTBD1 and BTBD2 interact with one HIV-1 viral tropism factor, TOP1, and co-localize with a splice variant of another, we investigated the potential involvement of BTBD1 and BTBD2 in HIV-1 restriction.

Zyxin interacts with the SH3 domains of the cytoskeletal proteins LIM-nebulette and Lasp-1

Zyxin is a versatile component of focal adhesions in eukaryotic cells. Here we describe a novel binding partner of zyxin, which we have named LIM-nebulette. LIM-nebulette is an alternative splice variant of the sarcomeric protein nebulette, which, in contrast to nebulette, is expressed in non-muscle cells. It displays a modular structure with an N-terminal LIM domain, three nebulin-like repeats, and a C-terminal SH3 domain and shows high similarity to another cytoskeletal protein, Lasp-1 (LIM and SH3 protein-1). Co-precipitation studies and results obtained with the two-hybrid system demonstrate that LIM-nebulette and Lasp-1 interact specifically with zyxin. Moreover, the SH3 domain from LIM-nebulette is both necessary and sufficient for zyxin binding. The SH3 domains from Lasp-1 and nebulin can also interact with zyxin, but the SH3 domains from more distantly related proteins such as vinexin and sorting nexin 9 do not. On the other hand, the binding site in zyxin is situated at the extreme N terminus as shown by site-directed mutagenesis. LIM-nebulette and Lasp-1 use the same linear binding motif. This motif shows some similarity to a class II binding site but does not contain the classical PXXP sequence. LIM-nebulette reveals a subcellular distribution at focal adhesions similar to Lasp-1. Thus, LIM-nebulette, Lasp-1, and zyxin may play an important role in the organization of focal adhesions.

Crystal structures of progressive Ca2+ binding states of the Ca2+ sensor Ca2+ binding domain 1 (CBD1) from the CALX Na+/Ca2+ exchanger reveal incremental conformational transitions.

Na(+)/Ca(2+) exchangers (NCX) constitute a major Ca(2+) export system that facilitates the re-establishment of cytosolic Ca(2+) levels in many tissues. Ca(2+) interactions at its Ca(2+) binding domains (CBD1 and CBD2) are essential for the allosteric regulation of Na(+)/Ca(2+) exchange activity. The structure of the Ca(2+)-bound form of CBD1, the primary Ca(2+) sensor from canine NCX1, but not the Ca(2+)-free form, has been reported, although the molecular mechanism of Ca(2+) regulation remains unclear. Here, we report crystal structures for three distinct Ca(2+) binding states of CBD1 from CALX, a Na(+)/Ca(2+) exchanger found in Drosophila sensory neurons. The fully Ca(2+)-bound CALX-CBD1 structure shows that four Ca(2+) atoms bind at identical Ca(2+) binding sites as those found in NCX1 and that the partial Ca(2+) occupancy and apoform structures exhibit progressive conformational transitions, indicating incremental regulation of CALX exchange by successive Ca(2+) binding at CBD1. The structures also predict that the primary Ca(2+) pair plays the main role in triggering functional conformational changes. Confirming this prediction, mutagenesis of Glu(455), which coordinates the primary Ca(2+) pair, produces dramatic reductions of the regulatory Ca(2+) affinity for exchange current, whereas mutagenesis of Glu(520), which coordinates the secondary Ca(2+) pair, has much smaller effects. Furthermore, our structures indicate that Ca(2+) binding only enhances the stability of the Ca(2+) binding site of CBD1 near the hinge region while the overall structure of CBD1 remains largely unaffected, implying that the Ca(2+) regulatory function of CBD1, and possibly that for the entire NCX family, is mediated through domain interactions between CBD1 and the adjacent CBD2 at this hinge.
