Estudio comparativo entre Cataluña y Asturias de representaciones lingüísticas en Educación Primaria: autorretratos y plurilingüismo: A comparative study of linguistic representations between Catalonia and Asturias in Primary Education: self-portraits and plurilingualism

This study responds to a joint research done by the Faculty of Education (University of xxxxxx) and the Faculty xxxxxx (University of xxxxxx). With a general purpose of contributing to new multilingual and intercultural approaches, the specific objectives are a) analyze the representations of primary school students -through their linguistic self-portraits- about the languages that make up their repertoires; b) to identify and classify the associations established with the languages in their self-portraits; c) to compare these associations in two bilingual communities. The results show the symbolic value participants give to the languages of their repertories in those communities. A crucial component in the construction of linguistic identity and in learning. This study is of great importance not only because of the results, given the characteristics of the territories with their contexts, models and policies, but also for the transferability of the methodological design used, applicable to the study of other international bilingual -and multilingual- contexts of interest.Este estudio responde a una investigación conjunta de la Facultad de Educación (Universidad de Barcelona) y la Facultad Padre Ossó (Universidad de Oviedo). Con un propósito general de contribuir a nuevos enfoques plurilingües e interculturales, los objetivos específicos han permitido a) analizar las representaciones de los estudiantes sobre sus repertorios lingüísticos; b) identificar y clasificar las asociaciones establecidas con las lenguas en sus autorretratos; c) comparar estas asociaciones en dos comunidades bilingües. Los resultados muestran el valor simbólico que los participantes otorgan a las lenguas de sus repertorios en estas comunidades, un componente crucial este en la construcción de la identidad lingüística y en el aprendizaje. El estudio es relevante no solo por los resultados, dadas las características de los territorios con contextos, modelos y políticas lingüísticas diferenciados, sino, además, por la transferibilidad del diseño metodológico empleado, aplicable al estudio de otros contextos bilingües –y multilingües– internacionales de interés.

Predicting the physicochemical properties and geographical ORIGIN of lentils using near infrared spectroscopy

[EN]Calibration statistical descriptors for both whole and ground lentils using Near Infrared Spectroscopy (NIRS), combined with fiber-optic probe, are presented and discussed. The models were developed for estimating the weight, size, total raw protein, moisture, total fat, total fiber, and ash. Standard methods were used to determine compositional parameters of 42 samples of different varieties of lentils. The calibration curves show a wide range of validity for all parameters. The results showed excellent predictability for the determination of weight, fiber, and ash in whole lentils. However, size, moisture, and total fat were predicted satisfactorily in ground lentils. The total protein content could be predicted for both whole and ground lentils. Moreover, NIRS and Direct Partial Least Squares (DPLS) were used to determine whether a sample of lentils belonged to the Protected Geographical Indication (PGI) “Lenteja de La Armuña” or not. The results showed that 95% of the samples were correctly classified as belonging to a PGI. This result demonstrates that this technique allows the differentiation of samples from nearby regions

Mannose-binding lectin gene variants and infections in patients receiving autologous stem cell transplantation

BACKGROUND: Serious infections are common in patients undergoing autologous stem cell transplantation (ASCT) mainly because of the effects of immunosuppression. The innate immune system plays an important role in the defense against different infections. Mannose binding lectin (MBL) is a central molecule of the innate immune system. There are several promoter polymorphisms and structural variants of the MBL2 gene that encodes for this protein. These variants produce low levels of MBL and have been associated with an increased risk for infections. METHODS: Prospective cohort study. The incidence, severity of infections and mortality in 72 consecutive patients with hematologic diseases who underwent ASCT between February 2006 and June 2008 in a tertiary referral center were analyzed according to their MBL2 genotype. INNO-LiPA MBL2 was used for MBL2 gene amplification and genotyping. Relative risks (RR) (IC95%) as measure of association were calculated. Multivariate analysis was performed using logistic regression. RESULTS: A statistically significant higher number of fungal infections was found in patients with MBL2 variants causing low MBL levels (21.1%versus1.9%, p=0.016). In this MBL2 variant group infection was more frequently the cause of mortality than in the MBL2 wild-type group (p=0.05). Although not statistically significant, there was a higher incidence of major infections in the MBL2 variant group as well as a higher number of infections caused by gram-positive bacteria. CONCLUSIONS: Low-producer MBL2 genotypes were associated with an increased number of fungal infections in ASCT patients, which would suggest that MBL has a protective role against such infections. ASCT patients with MBL2 variant genotypes are more likely to die as a result of an infection

Efecto coagulante de dos variedades de hoja de coca en muestras de sangre de ratas albinas

This investigation evaluates the clotting effect of extracts of two varieties of coca leaves: Erytrhoxylum coca var. Coca and novogranatense Erytrhoxylum var. Truxillense. The aim of the study was to determine the shortest time of clotting of the blood samples of the albin rats. 34 males and female rats were selected to have 3 ml. of blood of each one. The blood samples were distributed in three probes containing: 0,06 ml. of physiological serum (control group), 0,06 ml. extract of E. coca lam var. coca (coca group), and 0,06 ml. of extract E. novogranatense var. truxillense (truxillense group). The clotting time for the control group was of 1,42 (±0.31) min, coca group: 1,38 (±0.26) min, truxillense group 1,83 (±0.55) min. The Anova analysis of the results showed significant differences between groups (p<0.01). The coca group showed the shortest clotting time of all groups. The truxillense group showed an inhibiting clotting effect compared to control group.En la presente investigación se evaluó el efecto coagulante de los extractos de dos variedades de hoja de coca: Erytrhoxylum coca lam var. Coca y Erytrhoxylum novogranatense var. Truxillense. El objetivo fue determinar el menor tiempo de coagulación de muestras de sangre de ratas albinas, tratadas con los extractos. Se seleccionó una muestra de 34 ratas, machos y hembras, a las cuales se le extrajeron 3 ml de sangre a cada una, colocando 1ml de sangre en tubos que contenían 0.06 ml de suero fisiológico (grupo control), 0.06 ml de extracto de E. coca lam var. Coca (grupo coca), y 0.06 ml de extracto E. novogranatense var. Truxillense (grupo truxillense). Los tiempos de coagulación de las muestras del grupo control fue de 1.42 min (±0.31), el grupo coca obtuvo 1.38 min (±0.26) y el grupo truxillense 1.83 min (±0.55). Los promedios fueron comparados con Anova obteniendo diferencias significativas entre los grupos (p<0.01). Se encontró que el grupo coca produjo el menor tiempo de coagulación que los otros dos grupos. El grupo truxillense mostró un efecto inhibidor de la coagulación comparado al grupo control

Noninvasive monitoring of serial changes in pulmonary vascular resistance and acute vasodilator testing using cardiac magnetic resonance

Objectives The study sought to evaluate the ability of cardiac magnetic resonance (CMR) to monitor acute and long-term changes in pulmonary vascular resistance (PVR) noninvasively. Background PVR monitoring during the follow-up of patients with pulmonary hypertension (PH) and the response to vasodilator testing require invasive right heart catheterization. Methods An experimental study in pigs was designed to evaluate the ability of CMR to monitor: 1) an acute increase in PVR generated by acute pulmonary embolization (n = 10); 2) serial changes in PVR in chronic PH (n = 22); and 3) changes in PVR during vasodilator testing in chronic PH (n = 10). CMR studies were performed with simultaneous hemodynamic assessment using a CMR-compatible Swan-Ganz catheter. Average flow velocity in the main pulmonary artery (PA) was quantified with phase contrast imaging. Pearson correlation and mixed model analysis were used to correlate changes in PVR with changes in CMR-quantified PA velocity. Additionally, PVR was estimated from CMR data (PA velocity and right ventricular ejection fraction) using a formula previously validated. Results Changes in PA velocity strongly and inversely correlated with acute increases in PVR induced by pulmonary embolization (r = –0.92), serial PVR fluctuations in chronic PH (r = –0.89), and acute reductions during vasodilator testing (r = –0.89, p ≤ 0.01 for all). CMR-estimated PVR showed adequate agreement with invasive PVR (mean bias –1.1 Wood units,; 95% confidence interval: –5.9 to 3.7) and changes in both indices correlated strongly (r = 0.86, p < 0.01). Conclusions CMR allows for noninvasive monitoring of acute and chronic changes in PVR in PH. This capability may be valuable in the evaluation and follow-up of patients with PH
