Este artigo tem como foco a proposição de um novo modelo de formação no âmbito da graduação em enfermagem. Nesse contexto, foram configurados os códigos moduladores da ação pedagógica, bem como os sistemas referenciais que lhes dão sustencão.

Organization of lin genes and IS6100 among different strains of hexachlorocyclohexane-degrading Sphingomonas paucimobilis: evidence for horizontal gene transfer.

The organization of lin genes and IS6100 was studied in three strains of Sphingomonas paucimobilis (B90A, Sp+, and UT26) which degraded hexachlorocyclohexane (HCH) isomers but which had been isolated at different geographical locations. DNA-DNA hybridization data revealed that most of the lin genes in these strains were associated with IS6100, an insertion sequence classified in the IS6 family and initially found in Mycobacterium fortuitum. Eleven, six, and five copies of IS6100 were detected in B90A, Sp+, and UT26, respectively. IS6100 elements in B90A were sequenced from five, one, and one regions of the genomes of B90A, Sp+, and UT26, respectively, and were found to be identical. DNA-DNA hybridization and DNA sequencing of cosmid clones also revealed that S. paucimobilis B90A contains three and two copies of linX and linA, respectively, compared to only one copy of these genes in strains Sp+ and UT26. Although the copy number and the sequence of the remaining genes of the HCH degradative pathway (linB, linC, linD, and linE) were nearly the same in all strains, there were striking differences in the organization of the linA genes as a result of replacement of portions of DNA sequences by IS6100, which gave them a strange mosaic configuration. Spontaneous deletion of linD and linE from B90A and of linA from Sp+ occurred and was associated either with deletion of a copy of IS6100 or changes in IS6100 profiles. The evidence gathered in this study, coupled with the observation that the G+C contents of the linA genes are lower than that of the remaining DNA sequence of S. paucimobilis, strongly suggests that all these strains acquired the linA gene through horizontal gene transfer mediated by IS6100. The association of IS6100 with the rest of the lin genes further suggests that IS6100 played a role in shaping the current lin gene organization.

(Re)constituer un espace public et promouvoir le débat sans prendre position

This paper presents the analysis of a website created in 2011 by the Federal Office of Public Health (FOPH) to support an information campaign about the organ donation. Observing how a Swiss institution publicly communicates about an issue belonging to the private sphere, this paper describes how the semiotic and discursive resources are mobilised to meet specific goals: promoting discussion and decision about the organ donation while maintaining complete neutrality about the topic. In order to do this, we first discuss the issue of publicising organ donation in Switzerland; then we conduct a detailed analysis of the website to understand the role of the linguistic forms and structures in the communication strategy of the FOPH. This strategy relies on the representation of a public sphere in which ordinary people express conflicting positions about organ donation.

Revised definitions of invasive fungal disease from the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group.

BACKGROUND: Invasive fungal diseases are important causes of morbidity and mortality. Clarity and uniformity in defining these infections are important factors in improving the quality of clinical studies. A standard set of definitions strengthens the consistency and reproducibility of such studies. METHODS: After the introduction of the original European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group definitions, advances in diagnostic technology and the recognition of areas in need of improvement led to a revision of this document. The revision process started with a meeting of participants in 2003, to decide on the process and to draft the proposal. This was followed by several rounds of consultation until a final draft was approved in 2005. This was made available for 6 months to allow public comment, and then the manuscript was prepared and approved. RESULTS: The revised definitions retain the original classifications of "proven," "probable," and "possible" invasive fungal disease, but the definition of "probable" has been expanded, whereas the scope of the category "possible" has been diminished. The category of proven invasive fungal disease can apply to any patient, regardless of whether the patient is immunocompromised, whereas the probable and possible categories are proposed for immunocompromised patients only. CONCLUSIONS: These revised definitions of invasive fungal disease are intended to advance clinical and epidemiological research and may serve as a useful model for defining other infections in high-risk patients.

Complex organization of CTF/NF-I, C/EBP, and HNF3 binding sites within the promoter of the liver-specific vitellogenin gene.

Vitellogenin genes are expressed specifically in the liver of female oviparous vertebrates under the strict control of estrogen. To explain this tissue-specific expression, we performed a detailed analysis of the Xenopus laevis vitellogenin gene B1 promoter by DNase I footprinting and gel mobility-shift assays. We characterized five binding sites for the ubiquitous factor CTF/NF-I. Two of these sites are close to the TATA-box, whereas the others are located on both sides of the estrogen responsive unit formed by two imperfect estrogen response elements. Moreover two liver-enriched factors, C/EBP and HNF3, were found to interact with multiple closely spaced proximal promoter elements in the first 100 base pairs upstream of the TATA-box. To confirm the physiological significance of this in vitro analysis, in vivo DNase I footprinting experiments were carried out using the ligation-mediated polymerase chain reaction technique. The various cis-elements characterized in vitro as binding sites for known transcription factors and more particularly for liver-enriched transcription factors are efficiently recognized in vivo as well, suggesting that they play an important role in the control of the liver-specific vitellogenin gene B1 expression.

'Se dire similaire et différent': la (re)présentation de soi et la négociation discursive des références identitaires des ressortissants ex-yougoslaves musulmans au Luxembourg

Cette thèse, qui se base sur des entretiens qualitatifs, porte sur la négociation des références identitaires de musulmans immigrés et réfugiés en provenance de Γ ex-Yougoslavie au Luxembourg et s'intéresse à la pertinence changeante de la religion dans la conception de soi. Selon une approche constructiviste et interactionniste, l'identité est conçue comme un projet constamment négocié, reconstruit dans des processus d'interaction sociale et en fonction des contextes sociaux. Nos données suggèrent l'émergence de constructions identitaires complexes et attestent de la pluridimensionalité et de l'intersectionnalité des références identitaires utilisées dans la conception de soi et témoignent de la non-réduction des individus à des catégories fixes. Différentes catégories sont rendues significatives et de multiples frontières sont établies afin de se différencier de figures d'altérité changeantes, sélectivement choisies pour construire une certaine image de soi. Les discours identitaires témoignent de l'aspiration à une identité positive, dans une situation caractérisée par la perte du statut social et des stigmatisations multiples, en tant que ex-Yougoslaves, demandeurs d'asile et musulmans. Nos interlocuteurs établissent un répertoire identitaire composé de marqueurs transposés, inventés et revalorisés, leur permettant de reconstruire une identité positive pour soi et leurs audiences. Ce travail décrit les manières dont les individus établissent leur répertoire identitaire à l'aide de marqueurs transposés, inventés et revalorisés, leur permettant de reconstruire une identité positive pour soi et leurs audiences et montre comment les processus de différenciation de 'l'autre' dans le pays d'origine et d'accueil sont reliés. - The question addressed in this project with a qualitative design, is how muslim migrants and refugees from the former Socialist Federal Republic of Yugoslavia in Luxemburg negotiate salient identity references in a new social political environment and discusses the changing significance of religion and the way it is integrated in the identity patchwork. According to a constructivist and interactionist approach, conceiving identity as a constantly negotiated project, reconstructed in interaction and with regard to social context, identities are relevant only in relation to particular other groups and in certain situations of interaction. Our data suggest the emergence of complex identity patterns using multiple references for self- description and attest of the intersectionnality of identity references and show that individuals can't be reduced to fixed categories. Different categories are made salient and multiple symbolic boundaries are established in order to differentiate from different "others", selected in order to construct a certain self-concept. The discourses of our participants attest of an aspiration towards a positive identity in a situation characterized by the loss of social status and multiple stigmata. This thesis describes the ways how individuals establish their identity repertoire with invented, transposed and negotiated identity references, that allow them to construct a favourable identity for themselves and their public and shows how différenciation processes in home and host country are related.

Re-significações do humano no contexto da 'ciborguização': um olhar sobre as relações humano-máquina na terapia intensiva

Discutem-se relações humano-máquina do processo denominado 'ciborguização da enfermeira' na terapia intensiva, com base nos Estudos Culturais pós-estruturalistas, destacando-se o conceito de ciborgue de Haraway. Examinam-se, como textos culturais, manuais utilizados pela enfermagem nas UTI. Esta análise cultural procura tensionar sentidos de 'humano e máquina', com o objetivo de reconhecer processos que instituem enfermeiras como ciborgues. Argumenta-se que enfermeiras intensivistas são inseridas em um processo de corporificação de tecnologia que transforma o corpo-profissional em um híbrido que permite desqualificar, concomitantemente, noções como máquina e corpo 'em si já que é a hibridização entre 'um e outro' que conta, ali. Como ciborgues, enfermeiras intensivistas aprendem a 'estar com' a máquina e essa conexão delimita a especificidade de suas ações. Sugere-se que processos de ciborguização como esse são produtivos para questionar - e lidar de outros modos com - os sentidos de 'humano' e 'humanidade' que sustentam grande parte do saber/fazer em saúde.
