A aprendizagem e a apropriação significativa da língua escrita por surdos podem ser promovidas por meio da utilização de tecnologias de comunicação amplamente difundidas. Este trabalho apresenta a análise dos recursos narrativos utilizados por três adolescentes surdos fluentes em LIBRAS para organizar sua experiência vivida através de produções escritas em weblogs (utilizando a língua portuguesa, sua segunda língua). Trata-se de um estudo qualitativo, do tipo exploratório. Propôs-se uma análise hermenêutica das narrativas baseada em Paul Ricoeur. Apesar dos erros na escrita, as produções puderam ser consideradas como narrativas, pois exprimem tentativas de tecer histórias. Porém, nem sempre a transmissão do sentido foi bem sucedida, indicando dificuldades na aprendizagem da língua escrita e na compreensão de que esta pode ser um meio de comunicação com o outro. Ressalta-se a necessidade de se criar estratégias que reforcem a noção da língua escrita como meio de produção de sentido.

The learning and the meaningful appropriation of the written language by the deaf can be promoted by means of the use of widely spread and available communication technologies. This work presents the analysis of the narrative resources used by three deaf adolescents fluent in Libras to organize their lived experience through written productions in weblogs (using the Portuguese language, their second language). It is a qualitative exploratory study. A hermeneutic analysis of the narratives based on Paul Ricoeur was proposed. Although there were mistakes in the written language, the productions could be considered narratives because they express attempts to weave stories. However, the transmission of meaning was not always successful, indicating difficulties in the learning of the written language and in the understanding that it can be a means of communicating with the other. The need of creating strategies that strengthen the notion of the written language as a means of production of meaning is emphasized.

El aprendizaje y la apropiación significativa de la lengua escrita por sordos pueden ser promovidas por medio de la utilización de tecnologías de comunicación ampliamente difundidas. Este trabajo presenta el análisis de los recursos narrativos utilizados por tres adolescentes sordos fluentes en Libras (Lengua Brasileña de Señales) para organizar su experiencia vivida a través de producciones escritas en weblogs (utilizando la lengua portuguesa, su segunda lengua). Se trata de un estudio cualitativo, de tipo exploratorio. Se propuso un análisis hermenéutico de las narrativas con base en Paul Ricoeur. A pesar de los errores en la escritura, fue posible considerar las producciones como narrativas, pues exprimen intentos de tejer historias. Sin embargo, no siempre la transmisión del sentido fue exitosa, indicando dificultades en el aprendizaje de la lengua escrita y en la comprensión de que ésta puede ser un medio de comunicación con el otro. Se resalta la necesidad de crearse estrategias que refuercen la noción de la lengua escrita como medio de producción de sentido.

This work describes the volatile composition obtained by hidrodistillation of fresh leaves of Siparuna guianensis Aublet collected from Cuiabá (MT), Brazil. The composition of DCM extract of hydrolate was determined by GC-MS analysis and the results showed that the specie present a range of components according to their phenology and period of the leaves were collects. The highest volatile components yield was obtained during the reproductive period and the principal compound was the siparunone.

Some cyclopalladated compounds containing the azido group ligand and the (C-N) ring of N,N-dimethylbenzylamine have been prepared by bridge opening reactions of dimmer azide complex precursor with some diphosphines in different stoichiometric quantities. The neutral or ionic, mono or binuclear complexes synthesized were characterized by elemental analyses, I. R. spectroscopy and NMR techniques. The series of complexes was screened for cytotoxicity against a panel three human tumour cells lines(C6,Hep-2,HeLa). All complexes were found to be cytotoxic (IC50) at µM concentrations while one complex having the coordination bond N-Pd ruptured also displayed some differential cytotoxicity.

Given the suspected role of mycobacteria in the establishment of disorders with an autoimmune background and joint damage, a study was conducted to analize whether rheumatic symptoms were likely to be present in tuberculosis (TB) patients. To this end, 330 patients with a bacteriologic confirmation of tuberculosis were investigated for the presence of arthritic complaints. The latter were recorded in five of them with rheumatic symptoms mostly involving interphalangeal and metacarpophalanged joints, and preceding the clinical manifestations of the TB illness. Three out of these five patients remained arthritic by the time of the bacteriologic conversion and fulfilled the criteria for the diagnosis of rheumatoid arthritis. In the two remaining patients sputum negativization was accompanied by a disappearance of rheumatic manifestations. These patients were also assessed for their peripheral levels of major T cell subsets as well as for the presence of autoantibodies. Comparisons with a series of non-arthritic TB cases, rheumatoid arthritis patients, and controls revealed that presence of rheumatic manifestations was associated with a different profile of autoantibody formation and T cell subset changes. Evidence recorded in the present study indicates that joint affectation in TB is a rare event, being rather the exception than the rule.
