Cryptic SYT/SXX1 fusion gene in high-grade biphasic synovial sarcoma with unique complex rearrangement and extensive BCL2 overexpression

Synovial sarcomas are high-grade malignant mesenchymal tumors that account for 10% of all soft-tissue sarcomas. Almost 95% of these tumors are characterized by a nonrandom chromosomal abnormality, t(X;18)(p11.2;q11.2), that is observed in both biphasic and monophasic variants. In this article, we present the case of a 57-year-old woman diagnosed with high-grade biphasic synovial sarcoma in which conventional cytogenetic analysis revealed the constant presence of a unique t(18;22)(q12;q13), in addition to trisomy 8. The rearrangement was confirmed by fluorescence in situ hybridization. The use of the whole chromosome painting probes WCPX did not detect any rearrangements involving chromosome X, although reverse-transcriptase polymerase chain reaction (PCR) analysis demonstrated the conspicuous presence of a SYT/SXX1 fusion gene. Spectral karyotyping (SKY) was also performed and revealed an insertion of material from chromosome 18 into one of the X chromosomes at position Xp11.2. Thus, the karyotype was subsequently interpreted as 47,X,der(X)ins(X;18) (p11.2;q11.2q11.2),der(18)del(18)(q11.2q11.2)t(18;22)(q12;q13),der(22)t(18;22). Real-time PCR analysis of BCL2 expression in the tumor sample showed a 433-fold increase. This rare finding exemplifies that thorough molecular-cytogenetic analyses are required to elucidate complex and/or cryptic tumor-specific translocations. (C) 2010 Elsevier Inc. All rights reserved.

Strange bedfellows: Green Hill Fort, archaeology and tourism

Green Hill Fort, Thursday Islalld was constructed between 1891-1893 to defend the Australian colonies against a feared Russian invasion. It retained an operational role until the 1920.'1 and played a minor role in World /t'ar 2. From 1954 to 1993 the site, but not the facilities, was used as a weather station. More recently it has been home ofthe Ton-es Strait Historical Society and Museum Association museum. It is a major attraction during the tourist season and an important local icon. For archaeologists it has sign~ficance as a relatively intact nineteenth-century military installation. Two 'Centenary of Federation' grants have proVided the impetus to undertake conservation and presentation works involving various task -spec~fic, archaeological activities. At the management level archaeologists play the lead role in the project. The project has demonstrated the value oJarchaeology and tourism joining forces. The danger ofa 'theme park 'presentation has been avoided. Technical accuracy and careful site planning has ensured a high degree ofaccuracy is retained. Provided these qualities can be assured then, it is argued, there is an opportunity for archaeology to be a majOl; long-term beneficiary. But to achieve that, the discipline must move from being entrenched in its academic mould and become Jar more receptive to the broader needs ofthe twentyfirst century.

Entre rios, praias e planetas : travessias do congo da Barra do Jucu

O Espírito Santo abriga grande diversidade de expressões populares tradicionais que se dividem em grupos, saberes e celebrações. Uma das práticas mais evidentes são as bandas de Congo que abrangem grande parte do Estado e ganham cada vez mais notoriedade. A Barra do Jucu é uma das comunidades mais antigas do Espírito Santo, uma vila de pescadores que séculos atrás compunha parte da grande fazenda Araçatiba fundada pelos Jesuítas e administrada no século XIX pelo coronel Sebastião Vieira Machado. A diversidade cultural dessa região habitada por africanos, indígenas e europeus, propiciou o surgimento de práticas populares como a Marujada, a Folia de Reis e as Bandas de Congo, que persistem até hoje nos municípios de Cariacica, Vila Velha, Guarapari e Viana, no passado, pertencentes à grande fazenda Araçatiba. A formação do Congo na Barra do Jucu é resultado de rodas informais realizadas por conguistas de comunidades ribeirinhas vizinhas, promovidas principalmente pelo senhor Ignácio Vieira Machado, descendente do coronel Sebastião e lideradas por Alcides Gomes da Silva, descendente de negros africanos e açorianos habitantes da fazenda Araçatiba. Durante muito tempo essa prática foi marginalizada, mas atualmente o Congo é considerado um ícone da cultura capixaba. Essa ressignificação está ligada a um processo de valorização e projeção midiática que se iniciou nos anos 1980 e se intensificou nas décadas seguintes. Boa parte dos movimentos e eventos que estimularam esse processo ocorreu na comunidade da Barra do Jucu. Por outro lado, políticos, empresários, indústria do entretenimento e outros setores sociais, aproveitam cada vez mais dessa ascensão do Congo utilizando os grupos tradicionais para fins lucrativos e promocionais. De prática marginal até se tornar ícone cultural, o Congo da Barra do Jucu passou por fazendas, rios, praias e planetas. E sobre essas travessias não só geográficas, mas sociais, culturais e políticas é que este trabalho pretende refletir, além das práticas tradicionais dos grupos e seus usos, buscando trazer à tona as relações entre conguistas, instituições públicas e privadas, mídia e público.

Cidade-paisagem : novas perspectivas sobre a preservação da paisagem urbana no Brasil

The edification of the landscape in the scientific and social field, in speech as in the method, is taken in this study as a complex process, from which were developed relationships of dominance on the perception of space, which persist strongly consolidated, since the genesis of the conceptual practice till its actual praxis. Historically, the landscape studies took place slowly, immersed in many questions, in face of the multiplicity of meanings that the concept offers. In the psyche, the notion of landscape is present since a long time ago, as an unconscious human being practice, even before any ideological hypothesis formulation. However its materialization in the social conscious will come only from painting, and specially with the perspective, through the technicity of the view, at first wandering the infinity, now ordained in a frame‟. Since then, the landscape is perceived according to the order of the view, as the equivalent of nature and beauty, assuming at the same time, an important symbolic value, since it is linked to mnemonic and subjective processes that the being build with the territory. The domain on this space-cognitive experience, characteristic of the contemporary, consolidates in the social imaginary, building consensus on the landscape, whose aesthetic references make a cultural appeal, very pertinent to the actual capitalist dynamics of production the space worldwide, mainly of the spectacle and commodification of cities promoted by the city marketing. In Brazil, this consensual ideology of the landscape surpass the social imaginary and also dominates the political imaginary, whereas the main instrument for preserving the landscape, Decree-law 25, from November 30, 1937, and its limit to those of exceptional value or remarkable feature. The analysis of the processes for putting under governmental trust for inscription of goods by the landscape value, reveals the dominant, if not exclusive, adoption of selection criteria related to aesthetic aspects. Abstain, therefore, from what the nation considers patrimony , other landscapes that, besides not having, at first, remarkable aesthetic value, play a crucial role as an inheritance from ancestor relations between man and space and pre- existing condition for the same present and future relations. From this historical background, the research seeks to transfer into contemporaneity, the ideological analysis of the concept and its relation with the building of the landscape in the collective imaginary, in order to recognize, in current practices to landscape preservation, as much this genesis, rooted in aesthetics, remains strongly consolidated, feeding the current dynamics of consumption and commodification of the city. Therefore, as preliminary conclusion, one can state that the identification of landscapes of different value, especially aesthetic, maintains and intensify the treatment of the city as an object, a standard‟ commodity to be sold / traded on the world market, in detriment of its recognition as a dynamic process that, even though inserted in the global context, develops specificifities and peculiarities, inherent to the production of space, as Lefebvre preconizes, that is, to the production of life, social product , as characteristic, dissent generator

O Aplanamento das Imagens

A densidade visual da pintura flamenga e holandesa afirmou-se devido a uma nova forma de conceber o mundo e o olhar, fornecendo óptimos exemplos de comparação para com o actual cinema digital, desde as epopeias densamente habitadas por milhares de figurantes em programas de auto-gestão, até à densidade visual das layers de pósprodução. Christine Buci-Glucksmann chamou-lhe “olho cartográfico” e Svetlana Alpers “arte da descrição”. Ambos os conceitos lidam com um olhar nómada, presente também nos panoramas dos séculos XVIII e XIX, devido a enquadramentos arbitrários, mas onde os amplos espaços enquadrados, num ponto de vista ideal, por vezes funcionam como controlo do mundo através da “panoramização” do espaço, que lhe retira o relevo, as profundidades distantes e inacessíveis. Tudo está ao alcance do olho. As imagens tornaram-se semelhantes aos mapas, sendo que estes tinham projectado o mundo num plano. Isto gerou um efeito-superfície que se generalizou, transformando paredes em “peles digitais” e a profundidade na horizontalidade plana electrónica, como defende Buci-Gluksmann.
