Spatial shaping of cochlear innervation by temporally regulated neurotrophin expression.

2001

Previous work suggested qualitatively different effects of neurotrophin 3 (NT-3) in cochlear innervation patterning in different null mutants. We now show that all NT-3 null mutants have a similar phenotype and lose all neurons in the basal turn of the cochlea. To understand these longitudinal deficits in neurotrophin mutants, we have compared the development of the deficit in the NT-3 mutant to the spatial–temporal expression patterns of brain-derived neurotrophic factor (BDNF) and NT-3, using lacZ reporters in each gene and with expression of the specific neurotrophin receptors, trkB and trkC. In the NT-3 mutant, almost normal numbers of spiral ganglion neurons form, but fiber outgrowth t…

Coexpression of heat-evoked and capsaicin-evoked inward currents in acutely dissociated rat dorsal root ganglion neurons.

1997

Noxious heat is able to activate heat-sensitive nociceptors in the skin very rapidly, but little is known about the mechanisms by which heat is transduced. We used the whole-cell patch-clamp technique to study the effects of noxious heat and capsaicin on freshly dissociated rat dorsal root ganglion neurons in vitro. Using temperatures between 41 degrees C and 53 degrees C, 8 of 19 small neurons (phior = 30 microm) exhibited a heat-evoked inward current. All heat-sensitive neurons tested were also capsaicin-sensitive. Moreover, the heat response tended to be enhanced after capsaicin (360 +/- 150 pA versus 125 +/- 45 pA, P0.1, n = 7). Two of five heat-insensitive neurons were excited by capsa…

Il convertito che opera conversioni: san Dionigi nel «Dionysius» di Rosvita di Gandersheim

2016

In her seventh hagiographical poem, «Dionysius» (or «Passio sancti Dionysii egregii martyris»), Hrotsvit of Gandersheim (935-973) elaborates in 266 rhymed hexameters a story already told in the «Vita sancti Dionysii» of Hilduinus, abbot of Saint-Denis, composed about 835 by order of the emperor Louis the Pious, to whom he is devoted. Hrotsvit, in this work, presents the figure of Dionysius as a convert by the apostle Paulus, who consecrates his new Christian life to the conversion of the Pagans, until his martyrdom (which is under the topic of “cephalologie”, a recurring theme in classical and medieval lore). The poem has a big interest, both historical and literary. The paper presents and …

HYBRID WHITE LIGHT-EMITTING DIODES: STUDY AND FABRICATION OF THIN-FILM AND NANOWIRE-BASED DEVICES

I diodi ad emissione luminosa sono dei dispositivi a semiconduttore che posseggono straordinarie proprietà fisiche di generazione della luce. Il primo LED bianco si è mosso silenziosamente dalla metà degli anni 90 fino a un punto in cui, oggi, il mercato dell’illuminazione è stato totalmente rivoluzionato. A fronte dell’industria dell’illuminazione a stato solido che richiede LED sempre più luminosi ed economici, la ricerca scientifica risponde con strutture innovative, nuovi materiali più efficienti, anche combinati con l’uso delle nanotecnologie applicate. I diodi bianchi ibridi ad emissione luminosa, ad esempio, fanno anch’essi uso di un LED blu, come in un tradizionale diodo bianco, ma …

DNA Methylation and Non-Coding RNAs during Tissue-Injury Associated Pain.

2022

While about half of the population experience persistent pain associated with tissue damages during their lifetime, current symptom-based approaches often fail to reduce such pain to a satisfactory level. To provide better patient care, mechanism-based analgesic approaches must be developed, which necessitates a comprehensive understanding of the nociceptive mechanism leading to tissue injury-associated persistent pain. Epigenetic events leading the altered transcription in the nervous system are pivotal in the maintenance of pain in tissue injury. However, the mechanisms through which those events contribute to the persistence of pain are not fully understood. This review provides a summar…

Juan Fernández de Porto y su biblioteca jurídica (1383)

1988

LA COLECCION DE LIBROS DEL JURISTA JUAN FERNANDEZ DE PORTO CONSTITUYE UN EJEMPLO DE BIBLIOTECA JURIDICA PRIVADA BAJOMEDIEVAL. SE TRATA DE UNA BIBLIOTECA PROFESIONAL: LOS MANUSCRITOS DE DERECHO CANONICO O CIVIL -LOS LIBROS DE ESTUDIO, DE TRABAJO- SUPONEN LA MAYORIA DEL TOTAL DE VOLUMENES DE LA BIBLIOTECA. EN CAMBIO, LOS LIBROS DE CARACTER MORAL, PIADOSOS, ETC, -AQUELLOS QUE NO TIENEN UNA FINALIDAD PROFESIONAL, SINO PRIVADA, LITERARIA-, TAN SOLO SON UNA MINORIA. EL LIBRO ES EN ESTE CASO, UN UTIL DE TRABAJO, Y LA LECTURA SOLO UN INSTRUMENTO. SIN EMBARGO, SE PUEDE DESTINAR LA LECTURA A UN FIN TOTALMENTE DISTINTO: LOS TEXTOS RELIGIOSOS, LITERARIOS, CUMPLEN UNA FUNCION DE CUIDADO Y EDIFICACION DE…

Análisis una propuesta didáctica para trabajar la poesía en un aula de Primaria: leer a Leopoldo de Luis

2021

Muchas son las propuestas para llevar la lectura de un poema a un aula, aunque los resultados, a pesar de las buenas voluntades, no siempre son muy satisfactorios, quizá porque sea parte de una idea algo equivocada de lo que es un texto poético y de lo que este requiere. En este trabajo se pretende revisar todo ello, valorando, además, la idoneidad de un poema del poeta Leopoldo de Luis, sobre un partido de fútbol. Frente a esta propuesta se ha llevado a cabo toda una revisión seria de los resultados obtenidos en su aplicación, tanto en un aula de Primaria como en unos grupos de estudiantes universitarios. Los resultados son esclarecedores y también inquietantes en algunos sentidos, pues ev…

Indoor artificial lighting: Prediction of the circadian effects of different spectral power distributions.

2014

The study presented in this paper aims to evaluate if and how the environment affects the circadian impact of a light source by predicting circadian stimulus (CS) resulting from the exposure to different light scenes, using equations reported in studies by Rea et al. The main findings are: (1) Above 600 lx at eye level the increase of CS is little; (2) Between 50 lx and 200 lx at the eye level an increase of only 50 lx determines a significant increase of CS; (3) Light sources with correlated colour temperatures between 2900 K and 4200 K have similar impacts on the circadian system according to the calculation method used; (4) Even an almost neutral environment affects the circadian impact…
