Encontrabilidade da Informação: atributos e recomendações para ambientes informacionais digitais

At first, this paper presents the epistemological and theoretical bases that support the inclusion of an operational concept for the findability of information in the field of Information Science. In a second moment, it defines the key attributes and recommendations for the findability of information, with a view to their understanding in a practical perspective, from the epistemological and theoretical support presented. From a theoretical, exploratory, bibliographic and documentary study, the results reveal that epistemologically the findability of information fits in Information Science in post-custodial paradigm that focuses on access to information and is significantly influenced by Information and Communication Technologies. The theoretical conclusions of this concept focus on the evolution of the Web and from the perspective of the dimensions of language, where there is as pragmatic trend, as technological development that combines the actions taken by informational and institutional individuals in digital information environments. Given that these actions turn enable or not the findability of information, these individuals can be understood as mediators. Therefore, the concept of infocommunicational mediation is the basis for the findability of information. For its application in digital information environments, were defined attributes and guidelines which should be considered in the context of Information Architecture. The attributes characterizing the concept and guidelines point at practical actions for the design and for evaluation of the findability of information. Epistemological, theoretical and practical concepts addressed underpin the called operative concept in information science and should be further explored in this scientific field.

Colaboração entre professores e bibliotecários no contexto escolar

The school library is a preferential placefor the contact of students with various informationresources and action of librarians and teachers, likemediators in order to enhance this experience. Thecollaborative relationship between this mediators isessential for planning and implementing activitiesfor learning. This article discusses some aspects ofcollaborative work between teachers and librarianand presents the results of applying a model ofcollaboration with the two librarians in Marília-SP, Brazil. Data collection was conducted withlibrarians from two schools, through interviews.The analysis was performed using the technique ofcontent analysis from four models of collaboration.It is noticed that the models are applicable tothe brazilian context and that there is a model ofcooperation prevailing in the participating schools.KEYWORDS: School library. Librarian. Teacher.Colaboration. Information literacy.

O papel da mediação da informação nas universidades

The information process should be understood as essential to the success of any institution, mainly those that produce knowledge. Information mediation being part of this process must be understood as an action capable of directing the knowledge construction of individuals. The information mediation in universities is a way of mediating the knowledge generated within and outside the university environment, including its specialized audience and to society. Thus the concept of information mediation is discussed in this work and its role within universities and the role of information professionals as information mediators. The social responsibility of universities needs to be reaffirmed into the society and the information is a possible way for the success of this action.

Análise química, citotoxicidade e biocompatibilidade de cimentos de ionômero de vidro

Objetivo: O presente trabalho, dividido em três estudos, teve como objetivo geral identificar e quantificar a liberação de componentes e avaliar a citotoxicidade e a biocompatibilidade de cimentos de ionômero de vidro (CIVs). Método: Para o estudo 1, extratos dos CIVs Vitrebond (VB), Fuji Lining LC (FL), Vitremer (VM), Fuji II LC (FII), Ketac Fil Plus (KF) e Ketac Molar Easymix (KM) foram obtidos pela imersão de corpos-de-prova em meio de cultura celular (DMEM). Esses extratos (n=9 por grupo) foram analisados por eletrodo específico quanto à presença de flúor e por espectrometria de absorção atômica quanto à presença de alumínio e zinco. HEMA e iodobenzeno foram identificados por CG/EM (n=6). Para o estudo 2, células MDPC-23 foram colocadas em contato com os extratos dos CIVs por 24 horas. Em seguida, foram avaliadas a atividade da desidrogenase succínica (SDH) (n=8), a produção de proteína total (PT) (n=8), a atividade da fosfatase alcalina (FAL) (n=8) e a morfologia celular (n=2). Para o estudo 3, tubos de polietileno (n=24 por grupo) foram preenchidos com os CIVs e implantados no tecido subcutâneo de 42 ratos. Como grupo controle foi utilizada a guta-percha. Após 7 ou 15 dias de pós-operatório, metade dos espécimes de cada grupo e período (n=6) foi preparada para análise histológica, e os demais (n=6) para análise da expressão de genes que codificam para IL-1? e TNF-?. Resultados: Os extratos de todos os CIVs apresentaram uma concentração de flúor significativamente maior do que o meio de cultura DMEM (controle), tendo o VB liberado maior quantidade, estatisticamente significante, do que os demais CIVs. O VB foi, também, o único material que liberou quantidades relativamente altas de alumínio e de zinco. O HEMA foi identificado nos extratos de todos os CIVs modificados por resina (VB, FL, VM e FII), e o iodobenzeno... (Resumo completo, clicar acesso eletrônico abaixo)

Mycetoma caused by Nocardia brasiliensis in an immunocompetent patient

Dendritic cells play a central role in the regulation of immunological reactivity. The existence of functionally specialized populations of dendritic cells in the skin is a consequence of qualitatively different attacks on our organism. slanDCs are human inflammatory dendritic cells that are characterized by the specific expression of the carbohydrate 6-sulfo LacNAc (slan). After phenotypic maturation, slanDCs are capable of producing very high amounts of proinflammatory mediators such as IL-12, TNF-, IL-1 and IL-23. Recent data describe a potential role of slanDCs in a number of different diseases like psoriasis, lupus erythematosus, and tumors, thus opening up new areas of research on their respective pathogenesis. Furthermore, a slanDC-specific targeting system has been developed as a basis for direct therapeutic manipulation. Future challenges of slanDC research include deepening our understanding of the significance of slanDCs in the regulation of adaptive and innate immune responses, as well as translating this knowledge into therapeutic options.
