Los espectaculos de la tradición romano-pagana en la obra de Paulino de Nola

In this paper we study the presence of elements related to Roman games in the work of the bishop Paulinus of Nola (355-431 AD). References to shows in his work are not as abundant as they occurs among his contemporaries. Nevertheless, many of these references possess a great importance for us. Certainly, they are similar to other allusions made by his contemporaries; however they express the opinion of one of the most famous and prestigious bishops of the Late Antiquity about these popular exhibitions. In his writings we can see his criticism of the waste of wealth in the organization of the Roman games, and also the use of a metaphorical language with ludical reminiscences whose origins go back to Paul of Tarsu

Poesía mística y escepticismo en la obra de San Juan de la Cruz

Son muchas y muy diversas las influencias que San Juan de la Cruz recibió. Intentar demostrar la primacía de una de ellas sobre las demás es una labor tan improbable como empobrecedora ya que una obra de arte es siempre"algo más" que la suma de todas sus influencias intelectuales y literarias o condicionamientos biográficos y sociales. Es posible, sin embargo, conceptualizar ese"algo más" como un modo particular de asimilación que lo llevase a seleccionar y privilegiar ciertas influencias entre todas aquellas a las que estuvo sometido.

El mito de Don Juan

Los griegos crearon su religión con tanta riqueza imaginativa que los mitos que la forman se han convertido en uno de los pilares fundamentales de nuestra cultura; se han recreado en todas las artes y seguirá haciéndose...

La mejora de la calidad de vida de las personas con lesión medular: la transición del centro rehabilitador a la vida cotidiana desde la perspectiva de los usuarios

El retorno a la vida cotidiana para una persona con lesión medular después del periodo de rehabilitación en régimen hospitalario, es un proceso difícil no exento de dificultades y nuevos retos personales. En este trabajo nos planteamos identificar aquellos factores más relevantes que contribuyen a mejorar su calidad de vida, desde la perspectiva de las propias personas afectadas. Hemos realizado dos grupos de discusión: uno formado por 12 personas con paraplejia y otro formado por 6 personas con tetraplejia. El análisis de contenido realizado indica que, para los participantes existen dos dimensiones relacionadas con su percepción de calidad de vida una vez salen del centro de rehabilitación: a) necesidad de atención al entorno más próximo y b) preparación para el mundo real. Concluimos señalando la importancia de realizar programas de rehabilitación integral, que incluyan, rehabilitación física, aprendizaje de habilidades que posibiliten el máximo de independencia y autonomía personal y trabajo de apoyo a la familia

Dual role of LldR in regulation of the lldPRD operon, involved in l-Lactate metabolism in Escherichia coli.

The lldPRD operon of Escherichia coli, involved in L-lactate metabolism, is induced by growth in this compound. We experimentally identified that this system is transcribed from a single promoter with an initiation site located 110 nucleotides upstream of the ATG start codon. On the basis of computational data, it had been proposed that LldR and its homologue PdhR act as regulators of the lldPRD operon. Nevertheless, no experimental data on the function of these regulators have been reported so far. Here we show that induction of an lldP-lacZ fusion by L-lactate is lost in an lldR mutant, indicating the role of LldR in this induction. Expression analysis of this construct in a pdhR mutant ruled out the participation of PdhR in the control of lldPRD. Gel shift experiments showed that LldR binds to two operator sites, O1 (positions 105 to 89) and O2 (positions 22 to 38), with O1 being filled at a lower concentration of LldR. L-Lactate induced a conformational change in LldR that did not modify its DNA binding activity. Mutations in O1 and O2 enhanced the basal transcriptional level. However, only mutations in O1 abolished induction by L-lactate. Mutants with a change in helical phasing between O1 and O2 behaved like O2 mutants. These results were consistent with the hypothesis that LldR has a dual role, acting as a repressor or an activator of lldPRD. We propose that in the absence of L-lactate, LldR binds to both O1 and O2, probably leading to DNA looping and the repression of transcription. Binding of L-lactate to LldR promotes a conformational change that may disrupt the DNA loop, allowing the formation of the transcription open complex.

Pseudo-Próspero de Aquitania, Sobre la providencia de Dios. Introducción, texto latino revisado, traducción y comentario de Raúl Villegas Marín, Publicacions i edicions de la Universitat de Barcelona, Barcelona 2010, 346 pp. ISBN 9788447534869

El primer tercio del siglo V representó un momento muy convulso en la historia del Imperio Romano. Algunas zonas, como la Galia, se vieron inmersas en una crisis provocada principalmente por las devastaciones que poblaciones bárbaras estaban llevando a cabo, desde inicios de la centuria, en casi todo su territorio. El foedus pactado por el Imperio con los visigodos, por el cual éstos se establecían en Aquitania (418), lejos de representar una solución no hizo sino aumentar los problemas de convivencia entre galorromanos y germanos. El pesimismo cundió entre la población autóctona: la teología eusebiana que presentaba al Dios cristiano como garante de los bienes materiales a través de su culto ―siguiendo la tradicional ideología del do ut des― había fallado, y muchas conciencias cristianas se hundieron en la angustia al preg

La poética de Juan Carlos Onetti a través de sus artículos periodísticos

El presente ensayo analiza y verifica como en los artículos periodísticos de Onetti, escritos en su primera época, ya se dan las características y la visión de su posterior mundo de ficción. Se traza una línea paralela entre sus crónicas periodísticas y sus novelas o primeros cuentos para llegar a la Poética del autor.

Nihilismo y voluntad de engaño en El astillero, de Juan Carlos Onetti

Escanometria dos membros inferiores: revisitando Dr. Juan Farill

A escanometria pelo "método de Farill" é exame rotineiro na maioria dos serviços radiológicos. Ela permanece, há mais de meio século, como um método amplamente utilizado para diagnóstico da diferença entre os membros inferiores e seu respectivo tratamento pelos especialistas de diversas áreas. Contudo, detalhes na técnica do exame e na avaliação das medidas costumam ser ignorados ou negligenciados, comprometendo o resultado final. Este trabalho tem por objetivo divulgar os detalhes preconizados pelo autor, restaurando a precisão do método, bem como discuti-lo em relação aos demais métodos.

Extended Endoscopic Endonasal Approaches for Cerebral Aneurysms: Anatomical, Virtual Reality and Morphometric Study

Introduction. The purpose of the present contribution is to perform a detailed anatomic and virtual reality three-dimensional stereoscopic study in order to test the effectiveness of the extended endoscopic endonasal approaches for selected anterior and posterior circulation aneurysms. Methods. The study was divided in two main steps: (1) simulation step, using a dedicated Virtual Reality System (Dextroscope, Volume Interactions); (2) dissection step, in which the feasibility to reach specific vascular territory via the nose was verified in the anatomical laboratory. Results. Good visualization and proximal and distal vascular control of the main midline anterior and posterior circulation territory were achieved during the simulation step as well as in the dissection step (anterior communicating complex, internal carotid, ophthalmic, superior hypophyseal, posterior cerebral and posterior communicating, basilar, superior cerebellar, anterior inferior cerebellar, vertebral, and posterior inferior cerebellar arteries). Conclusion. The present contribution is intended as strictly anatomic study in which we highlighted some specific anterior and posterior circulation aneurysms that can be reached via the nose. For clinical applications of these approaches, some relevant complications, mainly related to the endonasal route, such as proximal and distal vascular control, major arterial bleeding, postoperative cerebrospinal fluid leak, and olfactory disturbances must be considered

Differences between genders in coping: different strategies or different stressors?

These study analysed gender specificity in coping behaviours by taking into account the types of problem faced by Spanish adolescents attending school. It was focused on the ten problems most frequently reported by participants (828 adolescents, 355 boys, and 473 girls; Mage = 14.07, SD = 1.34), which were classified using a multi-axial classification system. Coping was examined as a two separate measures of approach and avoidance coping, and as a combined measure indicating the predominant use of coping, and total coping effort. A MANCOVA and subsequent univariate tests were conducted to analyse the specificity of coping according to problem and gender, controlled by age. The results showed that the percentage of types of problems reported by adolescents differed according to gender. The influence of gender on coping was scarcely relevant when the type of problem was controlled for. There were no gender differences when the predominant type of coping was considered, but when a total coping effort measure was analysed girls showed more coping efforts than boys to face interpersonal relationship problems and personal illness. Keywords: adolescence, coping, gender differences, stressors.
