Escribir la ausencia, recordando a Orfeo: Lei dunque capirà de Claudio Magris

Abordamos el estudio de la recreación del mito clásico órfico que emprende Claudio Magris en Lei dunque capirà, una obra de factura mixta que emprende la reescritura de las dos pulsiones de la existencia humana, del eros y de la muerte, y se convierte en un libro de frontera, prototipo de la escritura nocturna de la que hablara Ernesto Sábato.We approach the study of the recreation of the classic Orphean myth that Claudio Magris undertakes in Lei dunque capirà, a work of mixed invoice in which the author carries out a process of rewriting on both drives of the human life (Eros and Thánatos) and therefore it turns into a border book, i.e. a prototype of what Ernesto Sábato called the nighty writing

Pasos en la nieve en la trayectoria poética de Jaime Siles

En la trayectoria poética de Jaime Siles, Pasos en la nieve (Tusquets 2004) constituye un reflejo de la evolución de un quehacer poético, que desde el diálogo con la tradición se dirige hacia un tipo de poesía más discursiva y meditativa. El poeta vuelve a un rasgo cultivado con anterioridad: la integración de la racionalidad reflexiva que incide en reflexiones filosóficas en torno de los grandes temas existenciales de la condición humana. Las referencias y temas utilizados, cercanos a la anécdota vital, trascienden la materialidad de lo vivido para ceder paso a una poesía metafísica, a una poética del conocimiento de amplia resonancia conceptual, en la que sobresale el gusto por la linealidad y exactitud, la presencia de términos de alta densidad conceptual y vocablos procedentes de la física o matemática. In his career as a poet, Jaime Siles shows with Pasos en la nieve (Tusquets 2004) the trace of poetry making. In this work, there is a dialogue with tradition to that ends up in more discursive and reflexive poetry. The poet comes back with a known feature: the integration of a reflexive rationality that deepens inside the great questions of the human being. The references and theme, close to vital anecdote, go from the ordinary living to a metaphysical poetry. A poetry of the knowledge appears that enhances the taste for lines and exactitude. Furthermore, a great number of terms from the mathematics and physic sciences are presented

Is the basal area of maize internodes involved in borer resistance?

<p>Abstract</p> <p>Background</p> <p>To elucidate the role of the length of the internode basal ring (LIBR) in resistance to the Mediterranean corn borer (MCB), we carried out a divergent selection program to modify the LIBR using two maize synthetic varieties (EPS20 and EPS21), each with a different genetic background. We investigated the biochemical mechanisms underlying the relationship between the LIBR and borer resistance. Selection to lengthen or shorten the LIBR was achieved for each synthetic variety. The resulting plants were analyzed to determine their LIBR response, growth, yield, and borer resistance.</p> <p>Results</p> <p>In the synthetic variety EPS20 (Reid germplasm), reduction of the LIBR improved resistance against the MCB. The LIBR selection was also effective in the synthetic variety EPS21 (non-Reid germplasm), although there was no relationship detected between the LIBR and MCB resistance. The LIBR did not show correlations with agronomic traits such as plant height and yield. Compared with upper sections, the internode basal ring area contained lower concentrations of cell wall components such as acid detergent fiber (ADF), acid detergent lignin (ADL), and diferulates. In addition, some residual 2,4-dihydroxy-7-methoxy-(2H)-1,4-benzoxazin-3-(4H)-one (DIMBOA), a natural antibiotic compound, was detected in the basal area at 30 days after silking.</p> <p>Conclusion</p> <p>We analyzed maize selections to determine whether the basal area of maize internodes is involved in borer resistance. The structural reinforcement of the cell walls was the most significant trait in the relationship between the LIBR and borer resistance. Lower contents of ADF and ADL in the rind of the basal section facilitated the entry of larvae in this area in both synthetic varieties, while lower concentrations of diferulates in the pith basal section of EPS20 facilitated larval feeding inside the stem. The higher concentrations of DIMBOA may have contributed to the lack of correlation between the LIBR and borer resistance in EPS21. This novel trait could be useful in maize breeding programs to improve borer resistance.</p

Brainiac Caspases: Beyond the Wall of Apoptosis

For the last two decades, caspases, a family of cysteine-aspartic proteases, have evolved from being considered solely as regulators of apoptosis or inflammation to having a wider range of functions. In this mini review, we focus on the most recent "non-apoptotic" roles of caspases in the CNS, particularly in neurons, astrocytes and oligodendrocytes. Non-apoptotic caspase functions in microglia have already been reviewed extensively elsewhere. Here we discuss the involvement of caspases in the activation of the inflammasome, autophagy, and non-apoptotic forms of cell death such as necroptosis and pyroptosis. Also, we review the involvement of caspases in synapses and the processing of aggregates key to neurodegenerative diseases such as Parkinson's, Alzheimer's and Huntington's diseases. Likewise, we mention the recently described involvement of caspases in mitochondrial biogenesis, which is a function independent of the enzymatic activity. We conclude discussing the relevance that "new" functions of caspases have in the CNS and the future of this field of researchEspaña Ministerio de Economía y Competitividad SAF2015-64171- R (MINECO/FEDER, EU)España Ministerio de Economía y Competitividad (Programa Ramón y Cajal: RYC-2017-21804

Traducción y estudio del poema “The Flaming Heart upon the Book and Picture of the Seraphicall saint Teresa”. Imaginería mística y barroca en Richard Crashaw”

Abordamos la traducción y estudio de uno de los poemas que Richard Crashaw dedicó a la Santa de Ávila: “The Flaming heart upon the Book and Picture of the Seraphicall saint Teresa”. Escribió su autor durante la Contra-Reforma que siguió al Concilio de Trento y que produjo en la Iglesia grandes frutos espirituales y poéticos con figuras de la talla de Joost van den Vondel (1587-1679), en Holanda y de Richard Crashaw, en Inglaterra –ambos conversos al catolicismo, desde el calvinismo y el anglicanismo, respectivamente–. Las principales fuentes de estudio han sido las biografías de David Lloyd (1668: 618) y de Anthony Wood (1691) y las ediciones de su obra, realizadas por Alexander Balloch Grosart (1872) y por Leonard Cyril Martin (1927)
