Bacteria isolated from marine sponges found off the coast of Rio de Janeiro, Brazil, were screened for the production of antimicrobial substances. We report a new Pseudomonas putida strain (designated P. putida Mm3) isolated from the sponge Mycale microsigmatosa that produces a powerful antimicrobial substance active against multidrug-resistant bacteria. P. putida Mm3 was identified on the basis of 16S rRNA gene sequencing and phenotypic tests. Molecular typing for Mm3 was performed by RAPD-PCR and comparison of the results to other Pseudomonas strains. Our results contribute to the search for new antimicrobial agents, an important strategy for developing alternative therapies to treat infections caused by multidrug-resistant bacteria.

Many studies show strong variation of health consumption between regions, suggesting that theses variations are related to the uncertainty of medical practice or to other factors related to health services or patients attitude. However the statistical interpretation of these variations is far from easy: apart from usual and specific information bias, there are statistical problems when observing incidence of events like health care consumption: it is in fact a rare event, which is observed within small population, and among regions with unequal number of person. Therefore, most of the variation reported might be well explained by a purely statistical phenomenon. This paper presents some aspects of this variability for three common indicators of variation, and suggest the use of ad hoc simulation to get statistical criteria.

Cet article rend compte du travail d'ingénierie dans le domaine des micro- et nanotechnologies (MNT) en explorant une diversité de lieux où technologies et sociétés sont coproduites : comités internationaux où sont définies des feuilles de route (roadmap), laboratoires de recherche où sont conçus de nouveaux dispositifs, plates-formes d'exploration et de transfert des nouvelles technologies vers l'industrie, grands programmes de recherche où chercheurs et entreprises façonnent des infrastructures sociotechniques et régulent l'inscription sociétale des nouveautés techniques. Il utilise le concept d'« ingénierie hétérogène » (Law, 1989) afin d'expliquer la capacité de transformation sociale des pratiques d'ingénierie. Il montre ainsi que la théorie de l'acteur-réseau peut produire une description des mécanismes à l'oeuvre lors d'une transition sociotechnique, depuis la construction de projets de laboratoire jusqu'à leur inscription dans la société, sans pour autant renoncer à « suivre les acteurs » - notamment les ingénieurs - et leurs pratiques concrètes et situées.

Subthalamic nucleus deep brain stimulation (STN-DBS) is a recognized treatment for advanced and severe forms of Parkinson's Disease. The procedure improves motor signs and often allows a reduction of the medication. The impact of the procedure on cognitive and neuropsychiatric signs of the disease is more debated and there is an international consensus for the need of a multidisciplinary evaluation of patients undergoing such programs, including a neuropsychiatric assessment. We present a review of the literature as well as the experience at our centre focused on the short and long term outcome on mood following STN-DBS.
