Ethno-pragmatique et prosodie. Présentation d'une hypothèse de recherche pluridisciplinaire dans le domaine des sciences du langage et de la culture

L'hypothèse de recherche que nous souhaitons vous présenter ici a pour objet l&s fonctions pragmatiques de Ia prosodie. L'ensemble de notre Projet de Recherche s'organise en effet autour d'une seule (mais fondamentale) hypothèse de travail: c'est dans et par Ia prosodie que pour Vessentiel le langage contribue activement à Ia construction du lien social. La formulation de cette hypothèse resulte des travaux que nous avons menés dans le champ de FAnthropologie des rites, étudiés dans une perspective sémiologique (au sens large), visant à mieux saisir dans quelle mesure et selon quelles modalités, dans et par le rite, Vordre du signe est signe de 1'ordreK Le rite constitue un système complexe de comrpunication symbolique qui contribue en effet activement à definir sur le plan sémantique et à structurer sur le plan dramaturgique les situations d'interaction sociale.

Adenovirus respiratory infection: significant increase in diagnosis using PCR comparing with antigen detection and culture methods

Adenovirus (AdV) respiratory infections are usually described as being associated with high mortality rates. Laboratory diagnosis is essential for the establishment of the appropriate therapy, and for guiding the implementation of preventive measures in order to prevent the spread of the infection. Aiming to analyze the sensitivity and specificity of the laboratorial diagnosis methods available, we compared antigen detection by indirect immunofluorescence assay (IF), and a specific nested polymerase chain reaction (PCR), to detect AdV in respiratory samples collected from patients admitted to hospital with acute respiratory disease. Positive samples were inoculated into a cell culture to confirm the results. We analyzed 381 samples from the nasopharyngeal aspirates collected during the year 2008; of these, 2.6% tested were positive for adenovirus through IF and 10% through PCR; positive isolation was obtained in 40% and 26% of these cases, respectively. Most infected patients were children under six months of age, and despite of the fact that a significant number of patients required intensive care, the mortality rate was low (5%). In conclusion, molecular methods were found to be useful for rapid diagnosis of adenovirus infections with higher sensitivity than antigen detection; their introduction permitted a significant increase in diagnoses of adenovirus infections.

Viability and molecular authentication of Coccidioides spp. isolates from the Instituto de Medicina Tropical de São Paulo culture collection, Brazil

Coccidioidomycosis is an emerging fungal disease in Brazil; adequate maintenance and authentication of Coccidioides isolates are essential for research into genetic diversity of the environmental organisms, as well as for understanding the human disease. Seventeen Coccidioides isolates maintained under mineral oil since 1975 in the Instituto de Medicina Tropical de São Paulo (IMTSP) culture collection, Brazil, were evaluated with respect to their viability, morphological characteristics and genetic features in order to authenticate these fungal cultures. Only five isolates were viable after almost 30 years, showing typical morphological characteristics, and sequencing analysis using Coi-F and Coi-R primers revealed 99% identity with Coccidioides genera. These five isolates were then preserved in liquid nitrogen and sterile water, and remained viable after two years of storage under these conditions, maintaining the same features.

Insulin reduces the requirement for serum in Plasmodium falciparum culture

Insulin added to Plasmodium falciparum cultures (0.2 IU/ml) reduced the requirement for human serum from ten to five percent. This represents an obvious advantage by its serum-sparing effect and by reducing the chances of using contaminated serum in cultures. The growth-promoting ability of insulin was observed eitherin culture- adapted P. falciparum or in newly-isolated samples.
