Signposts for Comprehensive Knowledge of CLIL Contexts

AbstractThe implementation of a bilingual program at higher education raises multiple questions to those involved. The uncertainty around such novel experience could be lessened if participants understood all the factors converging. This paper provides a list of elements and parameters to aid both present and prospective practitioners to deepen in the characteristics and factors of their contexts. This systematic approach to the knowledge of the context assembles several theoretical models and descriptors of the practice of teaching content through English at higher education. Special attention will be given to linguistic issues. The five- year experience of bilingual teaching at the Escuela de Ingeniería de Informática de Segovia (Universidad de Valladolid) is used to illustrate the models and descriptors

Las canteras de calizas de los interfluvios de los ríos Jarama-Tajuña-Tajo en la Comunidad de Madrid: Valoración de recursos.

Un conjunto de ca lizas situadas en los interfluvios de los ríos Jarama-Tajuña-Tajo en la Comunidad de Madrid, explotadas más intensamente en las últimas décadas, son estudiadas como recurso geológico. Estas cal izas pertenecen básicamente a la Unidad Superior del relleno neógeno de la Cuenca de Madrid y en menor proporción a la Unidad Terminal. Se analizan sus características para diferentes usos estableciéndose unas posibles reservas de mil millones de toneladas, que podríamos considerar prácticamente ilimitadas a efectos de la producción de cemento. Las propiedades químicas y mecánicas de estas calizas, así como la presencia de algunas fábricas tobáceas de notable belleza sugieren una explotación racional esca lonada de las ca lizas como: rocas ornamentales, áridos de machaqueo, cales, cargas , etc. Se aconseja una central ización de todas las expfotaciones existentes en dos o tres cortas diseñadas correctamente en cuanto a Ja minimización del impacto ambiental

Low prevalence of Cfr-mediated linezolid resistance among methicillin-resistant Staphylococcus aureus in a Spanish hospital: case report on linezolid resistance acquired during linezolid therapy

Linezolid is an effective antimicrobial agent to treat methicillin-resistant Staphylococcus aureus (MRSA). Resistance to linezolid due to the cfr gene is described worldwide. The present study aimed to analyze the prevalence of the cfr-mediated linezolid resistance among MRSA clinical isolates in our area. A very low prevalence of cfr mediated linezolid resistance was found: only one bacteremic isolate out of 2 215 screened isolates. The only linezolid resistant isolate arose in a patient, previously colonized by MRSA, following linezolid therapy. Despite the low rate of resistance in our area, ongoing surveillance is advisable to avoid the spread of linezolid resistance

A diet rich in cocoa attenuates N-nitrosodiethylamine-induced liver injury in rats

The effects of cocoa feeding against N-nitrosodiethylamine (DEN)-induced liver injury were studied in rats. Animals were divided into five groups. Groups 1 and 2 were fed with standard and cocoa-diet, respectively. Groups 3 and 4 were injected with DEN at 2 and 4 weeks, and fed with standard and cocoa-diet, respectively. Group 5 was treated with DEN, received the standard diet for 4 weeks and then it was replaced by the cocoa-diet. DEN-induced hepatic damage caused a significant increase in damage markers, as well as a decrease in the hepatic glutathione, diminished levels of p-ERK and enhanced protein carbonyl content, caspase-3 activity and values of p-AKT and p-JNK. The cocoa-rich diet prevented the reduction of hepatic glutathione concentration and catalase and GPx activities in DEN-injected rats, as well as diminished protein carbonyl content, caspase-3 activity, p-AKT and p-JNK levels, and increased GST activity. However, cocoa administration did not abrogate the DEN-induced body weight loss and the increased levels of hepatic-specific enzymes and LDH. These results suggested that cocoa-rich diet attenuates the DEN-induced liver injury. © 2009 Elsevier Ltd.
