An outbreak of trichomonosis in European greenfinches Chloris chloris and European goldfinches Carduelis carduelis wintering in Northern France.

Avian trichomonosis is a common and widespread disease, traditionally affecting columbids and raptors, and recently emerging among finch populations mainly in Europe. Across Europe, finch trichomonosis is caused by a single clonal strain of Trichomonas gallinae and negatively impacts finch populations. Here, we report an outbreak of finch trichomonosis in the wintering populations of Chloris chloris (European greenfinch) and Carduelis carduelis (European goldfinch) from the Boulonnais, in northern France.

Motivation factors for participation in GLBT sports league.

This study investigated those factors that motivate members of the GLBT (gay, lesbian, bisexual, transgender) community to participate in a GLBT sports league. Data from a survey of 1151 members of a Chicago GLBT sports association were analyzed using exploratory factor analysis to determine the variables that contributed most to explaining leisure motivation in this setting. Results showed that the intellectual and social factors were the primary factors in determining motivation in participation.

Wernicke encephalopathy and Creutzfeldt-Jakob disease.

We assessed the prevalence of Wernicke encephalopathy (WE) in all 657 cases suspected of Creutzfeldt-Jakob (CJD) referred from 2001 to 2006 to the French Neuropathology Network of CJD. Clinical, biological and imaging data were reviewed when the diagnosis of WE was made at autopsy. No CJD was found in five cases suspected of sporadic CJD.

Expression of P2Y receptors in cell lines derived from the human lung.

1. Northern blotting experiments have been performed with RNA extracted from several cell lines derived from the human lung in order to detect P2Y1, P2Y2, P2Y4 and P2Y6 mRNA. We have investigated the 1HAEo- and 16HBE14o- epithelial cell lines derived from the airway epithelium, the A549 cell line displaying properties of type II alveolar epithelial cells, the CALU-3 serous cells, the 6CFSMEo- submucosal cells and the HASMSC1 airway smooth muscle cells.

Hydrodynamic properties of mucins secreted by primary cultures of guinea-pig tracheal epithelial cells: determination of diffusion coefficients by analytical ultracentrifugation and kinetic analysis of mucus gel hydration and dissolution.

We have used two different approaches to determine hydrodynamic parameters for mucins secreted by guinea-pig tracheal epithelial cells in primary culture. Cells were cultured under conditions that promote mucous cell differentiation. Secreted mucins were isolated as the excluded fraction from a Sepharose CL-4B gel filtration column run under strongly dissociating conditions.
