The current article aims to update the discussion on the South American context making use of the theory of Regional Security Regional Complexes (RSC). It begins with a theoretical discussion, based on Buzan and Wæver's work. It then presents the hypothesis that, differently from what is assumed in the literature, the South American RSC is not a standard one, but a centred one, in which the centre is not a global power. An empirical analysis follows, showing that Brazil possesses the necessary resources, and has presented some cogent political initiatives, such as the creation of the Union of South American Nations (Unasur) and its Defense Council (SDC), but in other moments has been reluctant take a leadership role in South America. The analysis concludes that, regarding its configuration, the South American RSC corroborates the authors' hypothesis and that Brazil should consolidate its role at the centre of such a complex.

Trata-se de avaliar como a aproximação entre os países promovendo a integração regional incide sobre qualidade da democracia e como esta se apresenta no setor de defesa e segurança. A perspectiva adotada é que o grau de estabilidade nas relações civil-militares incide diretamente sobre a formulação e desenvolvimento da cooperação em segurança regional e na estabilidade da democracia latino-americana.

One of the high tuberculosis (TB) incidence countries in the world, Brazil is characterized by considerable differences in TB incidence on regional and state level. In the present study, we describe Brazilian spoligotypes of 1991 Mycobacterium tuberculosis complex (MTC) clinical isolates from patients residents of 11 states from different regions of the country, diagnosed between 1996 and 2005. By performing spoligotyping on a large number of M. tuberculosis clinical isolates, one of the main objectives of this study was to determine the major genotype families causing TB in Brazil and to verify the region-associated genotype distribution. We observed a total of 577 distinct spoligopatterns, 12.6% of these corresponded to orphan patterns while 87.4% belonged to 326 shared-types (SITs). Among the latter, 86 SITs (isolated from 178 patients) had been observed for the first time in this study, the most frequent being SIT2517 which belonged to the T3-ETH lineage and was exclusively found among patients residents of Belem, the capital of the state of Para (n = 8 isolates). Irrespective of shared-type labeling, a total of 19.5% strains were unique (unclustered) in our study as opposed to 80.5% clustered isolates (189 clusters, size range from 2 to 205 isolates). The three largest clusters were SIT42 of the Latin-America & Mediterranean (LAM) 9 clade (10.3%), SIT53 of the T clade (7.6%), and SIT50 of the Haarlem clade (5.4%). The predominant MTC lineages in Brazil in decreasing order belonged to the LAM (46%); the ill-defined T (18.6%); the Haarlem (12.2%), the X (4.7%), the S (1.9%), and the East African Indian (EAI) (0.85%) families. The rest of clades grouped together as Mycobacterium africanum, Mycobacterium bovis, Beijing, Central Asian (CAS), and the Manu types, represented less than 1% of the strains. Finally, about 15% of the isolates showed spoligotype signatures that were not yet classified among well-defined lineages. In conclusion, we provide hereby a first insight into the population structure of MTC isolates in Brazil, showing the predominance of both LAM and T family and the existence of region-associated genotypes.

JUSTIFICATIVA E OBJETIVOS: A Síndrome Dolorosa Complexa Regional (SDCR), assim denominada a partir de 1994 pelo Consenso da Associação Internacional para o Estudo da Dor (AIED) e anteriormente denominada de várias formas, tais como Distrofia Simpático Reflexa, Causalgia, Algodistrofia ou Atrofia de Sudeck, é uma doença cuja compreensão dos limites clínicos, fisiopatologia e implicações de patogenia ainda é pobre. Disto resulta a enorme insatisfação não só para os pacientes como para os profissionais da saúde quanto aos métodos terapêuticos atualmente disponíveis. O objetivo deste trabalho é rever a literatura e atualizar um conjunto de informações com o intuito da melhor compreensão desta importante síndrome dolorosa. CONTEÚDO: Este é um trabalho de revisão da literatura nos diversos aspectos da SDCR, com ênfase em suas causas, definição e taxonomia, fisiopatologia, características clínicas, testes diagnósticos e propostas de tratamentos mais recentes. CONCLUSÕES: Poucos são os estudos controlados adequadamente, encobertos e aleatórios, publicados com grandes amostras, havendo muitas dúvidas sobre esta doença. Desta forma, ainda há enorme empirismo na sua terapêutica, e os resultados obtidos são insatisfatórios.

The mafic/ultramafic Ipanema Layered Complex (ILC), Minas Gerais Brazil, consists of seven individual bodies. These units crosscut polyphase orthogneisses and interlayered paragneisses of the Paleoproterozoic Juiz de Fora Complex. Intrusive granitoids tectonically related to [lie Neoproterozoie Aracuai orogen are also present in the study area.A Sm-Nd whole-rock linear array for seven samples metapyoxenites, metaperidotiles, metagabbro. and meta-anorthosite) from the Santa Cruz massif, the largest body of the ILC. suggest that it was emplaced at 1104 +/- 78 Ma the original magma was derived from a depleted mantle source (epsilon(Ndt)= +3.8). U-Pb single-grain zircon stud of a meta-anorthosite yields all upper intercept age of 1719 +/- 4 Ma, which is interpreted to represent inheritance. The lower intercept at 630+/-3 Ma indicates (hat a Neoproterozoic tectonothermal episode overprinted the ILC, this event occurred under upper-amphiolite-, to granulite-facies conditions. The 630 Ma episode is consistent with the timing of regional metamorphism and deformation of the adjacent Aracuai orogen (Brasiliano collage). Emplacement of the ILC and other coeval metamafies and meta-ultramafics (of alkaline affinity) in the re, oil is attributed to early extension tectonics, accompanying accretion of the Rodinia super- continent during the Mesoproterozoic-Neoproterozoic time boundary.
