EL SOLO DE VIOLA EN LA OBRA DON QUIXOTE OP. 35 DE RICHARD STRAUSS

El tema objeto de este artículo trata sobre el solo de viola del poema sinfónico Don Quixote op. 35 de Richard Strauss. Este solo aparece en la tercera variación y tiene relación con la sinergia y el diálogo que mantienen los dos personajes principales de la ilustre obra de Miguel de Cervantes: Don Quijote y Sancho Panza. Por ello, es necesario trabajar y conocer la obra de Richard Strauss a fondo, así como identificar y estudiar los capítulos de Don Quijote de la Mancha a los que corresponden sus variaciones para poder compararlos y establecer una conexión entre ambas obras.Don Quixote op.35, de Richard Strauss, ha personalizado a uno de los personajes principales en el papel de la viola, dando así voz a un instrumento “poco destacado” en el ámbito de la música sinfónica. Además, el hecho de encontrar un solo de viola en una de sus variaciones imitando conversaciones entre el caballero andante y su escudero a lo largo de todo el relato de Miguel de Cervantes, propone la oportunidad de hallar una concordancia expresiva entre ambas obras y llegar a un punto en común: aportar una versión interpretativa que refleje el estudio de la personificación del personaje de Sancho Panza en la obra de Richard Strauss

The bHLH transcription factors TSAR1 and TSAR2 regulate triterpene saponin biosynthesis in Medicago truncatula

Plants respond to stresses by producing a broad spectrum of bioactive specialized metabolites. Hormonal elicitors, such as jasmonates, trigger a complex signaling circuit leading to the concerted activation of specific metabolic pathways. However, for many specialized metabolic pathways, the transcription factors involved remain unknown. Here, we report on two homologous jasmonate-inducible transcription factors of the basic helix-loop-helix family, TRITERPENE SAPONIN BIOSYNTHESIS ACTIVATING REGULATOR1 (TSAR1) and TSAR2, which direct triterpene saponin biosynthesis in Medicago truncatula. TSAR1 and TSAR2 are coregulated with and transactivate the genes encoding 3-HYDROXY-3-METHYLGLUTARYL-COENZYME A REDUCTASE1 (HMGR1) and MAKIBISHI1, the rate-limiting enzyme for triterpene biosynthesis and an E3 ubiquitin ligase that controls HMGR1 levels, respectively. Transactivation is mediated by direct binding of TSARs to the N-box in the promoter of HMGR1. In transient expression assays in tobacco (Nicotiana tabacum) protoplasts, TSAR1 and TSAR2 exhibit different patterns of transactivation of downstream triterpene saponin biosynthetic genes, hinting at distinct functionalities within the regulation of the pathway. Correspondingly, overexpression of TSAR1 or TSAR2 in M. truncatula hairy roots resulted in elevated transcript levels of known triterpene saponin biosynthetic genes and strongly increased the accumulation of triterpene saponins. TSAR2 overexpression specifically boosted hemolytic saponin biosynthesis, whereas TSAR1 overexpression primarily stimulated nonhemolytic soyasaponin biosynthesis. Both TSARs also activated all genes of the precursor mevalonate pathway but did not affect sterol biosynthetic genes, pointing to their specific role as regulators of specialized triterpene metabolism in M. truncatula

Análisis microbiológicos y físico - químicos como pruebas novedosas y determinantes en un caso de envenenamiento de la fauna silvestre en el sur de España

Poaching wildlife species and eradicating predators from game reserves are not considered crimes per se under Spanish legislation. Furthermore, in accordance with Spain?s Penal Code and Constitution, any doubt regarding a suspect?s guilt manda tes a judge/cr own prosecutor to rest a case without presenting charges. By contrast, the use of a substance with the intent to poison wildl ife is deemed both an offense according to the Wildlife Act (2003) and a crime under the Spanish Penal Code. Here we report on the atypical analysis of a unique piece of evidence that was retrieved during an on -site investigation into allegations of wildlife poaching and poisoning on a game reserve in southern Spain. The findings proved critical in linking other recovered evidence to the suspect and, in particular, showing intent to poison, which ultimately led to the closure of the case and the addition of another tool in the growing coffer of approaches for resolving similar cases in Andalucía. To our knowledge this is the first inst ance in which the presence of bacteria and evaluation of physico -chemical parameters have been used as integral pieces of evidence in a wildlife poisoning case

Insights into the fecal microbiota of captive Iberian lynx (Lynx pardinus)

The Iberian lynx (Lynx pardinus) is an endangered species restricted to several areas of Spain and Portugal. Its low genetic diversity likely provokes immune depression and high susceptibility to infectious diseases. The intestinal microbiota is closely related to host health and nutrition. In order to contribute to the knowledge of the Iberian lynx intestinal microbiota, fecal microbiota of captive specimens from two breeding centers (“La Olivilla” and “El Acebuche”), located in Southern Spain, were studied by Denaturing Gradient Gel Electrophoresis (DGGE). Results grouped microbiota in two main clusters (I and III) which included DGGE patterns of 19 out of 36 specimens, cluster I being the most frequent in “La Olivilla” (50%) and cluster III in “El Acebuche” (55.55 %) specimens. Bacteroidetes, Firmicutes and Proteobacteria phyla were identified. Segregation of clusters I and III was attributed to different microorganism presence (Pseudomonas koreensis, Pseudomonas migulae, Carnobacterium sp., Arthrobacter, Robinsoniella peorensis and Ornithinibacillus sp.) and ability to use different carbon sources. Biolog EcoPlates® results indicate high functional diversity of fecal microbiota, it being higher in cluster III. The great impact of intestinal microbiota on host health supports the importance of its microbial composition understanding. This study is the first report of captive Iberian lynx fecal microbiota composition. [Int Microbiol 20(1): 31-41 (2017)]Keywords: Iberian lynx (Lynx pardinus) · fecal microbiota · biodiversit

Análisis de dos instrumentos de evaluación para guiar la práctica educativa de los profesores vistos desde el marco de la teoría de la autodeterminación de Deci y Ryan

El mundo de la educación actual se caracteriza por la incertidumbre y diversos desafíos que hay que afrontar. Esto afecta al papel de los profesores como agentes motivadores de sus alumnos. Los educadores no solo necesitan disponer de un conjunto de recursos para implicar a los estudiantes en sus estudios. Lo primordial es contar con marcos teóricos válidos y ejemplares para orientar y mejorar sus prácticas docentes. Este trabajo analiza dos herramientas para guiar las prácticas educativas de la etapa de Educación Secundaria desde la óptica de la Teoría de la Autodeterminación - Self-Determination Theory (SDT) de Deci y Ryan: el Classroom Assessment Scoring System -Sistema para evaluar la dinámica de las aulas (CLASS) y el Questionnaire on Teacher Interaction - Cuestionario de Interacción del Profesor (QTI). Esta teoría, que cuenta con un importante soporte empírico, ilustra cómo contribuir a la mejora del proceso educativo, la motivación y la autodeterminación del alumnado, así como su desarrollo positivo.Educational world nowadays is characterized by uncertainty and enormous challenges. These affect the role of teachers as motivating agents of their students. Educators do not just need a set of resources to involve students in their studies. The main thing is to have valid and exemplary theoretical frameworks to guide and improve their teaching practices. This paper analyzes two tools to guide the educational practices of Secondary Education from the perspective of Self-Determination Theory (SDT) by Deci and Ryan: Classroom Assessment Scoring System (CLASS) and Questionnaire on Teacher Interaction (QTI). This theory, which has an important empirical support, illustrates how to contribute to the improvement of the educational process, the motivation and self-determination of students, as well as their positive development

Role of wild ruminants in the epidemiology of bluetongue virus serotypes 1, 4 and 8 in Spain

Although the importance of wild ruminants as potential reservoirs of bluetongue virus (BTV) has been suggested, the role played by these species in the epidemiology of BT in Europe is still unclear. We carried out a serologic and virologic survey to assess the role of wild ruminants in the transmission and maintenance of BTV in Andalusia (southern Spain) between 2006 and 2010
