Abstract:
The main aim of this project was to define the neurotrophin survival requirements of sensory neurons during the early stages of their development both in vivo and in vitro. The in vitro survival of neural crest-derived but not placode-derived cranial sensory neurons is promoted by several different neurotrophins early in their development. Neural crest-derived neurons subsequently lose responsiveness to all neurotrophins except NGF. Loss of responsiveness of neural crest-derived sensory neurons to BDNF and NT3 is associated with a marked shift in the dose responses of these neurons to higher n

The GABAergic system in adult sensory cortex is affected by sensory deprivation, but little is known about how this predominant inhibitory system is affected during ontogeny.

Abstract:
Background Trigeminal ganglion (TG) is a key player in processing noxious stimuli. Among many ligand-gated ion channels, trigeminal sensory neurons express on their membranes purinergic P2X3 receptors and capsaicin-sensitive transient receptor potential vanilloid 1 channels (TRPV1). These receptors are thought to be involved in pain transduction and pathophysiology of different pain syndromes, including migraine disorders. P2X3 and TRPV1 channels are continuously regulated by a variety of endogenous modulators, which, upregulating these receptors, can cause sensitization and promote developmen

Abstract:
INTRODUÇÃO: O tratamento das neoplasias malignas anorretais exige ressecções que podem levar ao surgimento de defeitos perineais extensos. Esses defeitos necessitam de reconstrução que deve ser realizada, preferencialmente, com retalhos. Dentre eles, destacamos o retalho perfurante da artéria pudenda interna, localizado no sulco glúteo, vascularizado por vasos perfurantes cutâneos da artéria pudenda interna, e inervado por ramos do nervo pudendo e do nervo cutâneo femoral posterior. Esse retalho apresenta diversas vantagens em comparação com os outros utilizados para reconstrução perineal, e o

Abstract:
Esta tesis se ha hecho principalmente para estudiar e investigar polímeros impresos (MIPs) con la intención de usarlos como sensores de larga vida. La línea de investigación de esta tesis es la dirigida a conseguir la integración de estas formaciones impresas dentro de una lengua electrónica (ET), que es la rama de especialización en la que se ha desarrollado principalmente este proyecto. Después de hacer una revisión de la literatura, que inicialmente se centraba en la aplicación de MIPs a un equipo electroquímico, un sensor voltamétrico impreso y un procedimiento sensitivo complementario, el
