Le "Protévangile de Jacques" en latin. Etat de la question et perspectives nouvelles

Dans la première partie, on décrit et classifie les témoins qui contribuent à la connaissance du Protévangile de Jacques (PJ) en latin : 23 mss latins, les évangiles irlandais de l'enfance du Liber Flavus Fergusiorum (LFF) et du Leabhar Breac (LB). On clarifie dans une seconde partie plusieurs questions touchant à la diversité des formes textuelles du PJ en Occident, démontrant l'existence d'au moins deux traductions latines indépendantes. (I) L'une, plutôt littérale, est conservée en partie dans Montpellier 55 (M2) et Paris, n.a.l. 718 (S). (II) L'autre, caractérisée par des amplifications, est représentée par 4 témoins : Sainte-Geneviève 2787 (G; texte presque complet); l'homélie Inquirendum est (ch. 1-8, mss KPRBDO); l'Evangile latin de l'enfance combinant une partie du PJ, le Pseudo-Matthieu et une source inconnue, de coloration docète (compilation J, 8 témoins); le récit du LFF (ch. 1-16). Une troisième traduction indépendante est peut-être attestée (mss TUE). On montre ainsi l'existence de deux étapes successives d'amplification de la traduction II (IIa et IIb), illustrant le besoin d'expliciter la narration concise du PJ original. Cette traduction amplifiée a servi de modèle à l'auteur du remaniement latin du Pseudo-Matthieu. On éclaire enfin les antécédents, les caractéristiques et l'évolution de J, qui a vu le jour avant 800. La présente étude trouvera son prolongement dans l'édition critique des diverses formes du Protévangile latin

Increased resistance to first-line agents among bacterial pathogens isolated from urinary tract infections in Latin America: time for local guidelines?

Emerging resistance phenotypes and antimicrobial resistance rates among pathogens recovered from community-acquired urinary tract infections (CA-UTI) is an increasing problem in specific regions, limiting therapeutic options. As part of the SENTRY Antimicrobial Surveillance Program, a total of 611 isolates were collected in 2003 from patients with CA-UTI presenting at Latin American medical centers. Each strain was tested in a central laboratory using Clinical Laboratory Standard Institute (CLSI) broth microdilution methods with appropriate controls. Escherichia coli was the leading pathogen (66%), followed by Klebsiella spp. (7%), Proteus mirabilis (6.4%), Enterococcus spp. (5.6%), and Pseudomonas aeruginosa (4.6%). Surprisingly high resistance rates were recorded for E. coli against first-line orally administered agents for CA-UTI, such as ampicillin (53.6%), TMP/SMX (40.4%), ciprofloxacin (21.6%), and gatifloxacin (17.1%). Decreased susceptibility rates to TMP/SMX and ciprofloxacin were also documented for Klebsiella spp. (79.1 and 81.4%, respectively), and P. mirabilis (71.8 and 84.6%, respectively). For Enterococcus spp., susceptibility rates to ampicillin, chloramphenicol, ciprofloxacin, and vancomycin were 88.2, 85.3, 55.9, and 97.1%, respectively. High-level resistance to gentamicin was detected in 24% of Enterococcus spp. Bacteria isolated from patients with CA-UTI in Latin America showed limited susceptibility to orally administered antimicrobials, especially for TMP/SMX and fluoroquinolones. Our results highlight the need for developing specific CA-UTI guidelines in geographic regions where elevated resistance to new and old compounds may influence prescribing decisions.

The second internal transcribed spacer of nuclear ribosomal DNA as a tool for Latin American anopheline taxonomy: a critical review

Among the molecular markers commonly used for mosquito taxonomy, the internal transcribed spacer 2 (ITS2) of the ribosomal DNA is useful for distinguishing among closely-related species. Here we review 178 GenBank accession numbers matching ITS2 sequences of Latin American anophelines. Among those, we found 105 unique sequences corresponding to 35 species. Overall the ITS2 sequences distinguish anopheline species, however, information on intraspecific and geographic variations is scarce. Intraspecific variations ranged from 0.2% to 19% and our analysis indicates that misidentification and/or sequencing errors could be responsible for some of the high values of divergence. Research in Latin American malaria vector taxonomy profited from molecular data provided by single or few field capture mosquitoes. However we propose that caution should be taken and minimum requirements considered in the design of additional studies. Future studies in this field should consider that: (1) voucher specimens, assigned to the DNA sequences, need to be deposited in collections, (2) intraspecific variations should be thoroughly evaluated, (3) ITS2 and other molecular markers, considered as a group, will provide more reliable information, (4) biological data about vector populations are missing and should be prioritized, (5) the molecular markers are most powerful when coupled with traditional taxonomic tools.

Construcción de los WordNets 3.0 para castellano y catalán mediante traducción automática de corpus anotados semánticamente

Este artículo describe una metodología de construcción de WordNets que se basa en la traducción automática de un corpus en inglés desambiguado por sentidos. El corpus que utilizamos está formado por las propias glosas de WN 3.0 etiquetadas semánticamente y por el corpus Semcor. Los resultados de precisión son comparables a los obtenidos mediante métodos basados en diccionarios bilingües para las mismas lenguas. La metodología descrita se está utilizando, en combinación con otras estrategias, en la creación de los WordNets 3.0 del español y catalán.

Open Educational Resources : Experiences of use in a Latin-American context

This paper presents practical experiences using Open educational Resources (OER) for basic and elementary education (K12), educational research and research training on two inter-institutional projects with the collaboration of thirteen higher education institutions and with the support of the Corporación de Universidades para el Desarrollo del Internet (CUDI) and by the Consejo Nacional de Ciencia y Tecnología (CONACYT) of Mexico and hosted by the Tecnológico de Monterrey. The first initiative is titled "Knowledge Hub for K-12 Education" with the main goal of enrich a catalog of Open Educational Resources for basic and elementary education (K-12) for Mexico and Spanish speaking countries in Latin-America. The main goal of the second initiative is to build a collection of Open Educational Resources for Mobile Learning to address the issue of educational research and research training.

Performance levels of four Latin American laboratories for the serodiagnosis of Chagas disease in Mexican sera samples

In nearly all of the previous multicentre studies evaluating serological tests for Trypanosoma cruzi infection, sera samples from Central or South American countries have been used preferentially. In this work we compared the reliability of the serological tests using Mexican sera samples that were evaluated in four independent laboratories. This included a reference laboratory in Brazil and three participant laboratories, including one in Central America and two in Mexico. The kappa index between Brazilian and Honduran laboratories reached 1.0 and the index for the Mexican laboratories reached 0.94. Another finding of this study was that the source of antigen did not affect the performance of the serological tests.
