Efecto pantalla y efecto Sísifo: dos fenómenos didácticos en la resolución de problemas por transferencia analógica
2014
Se presenta un estudio cualitativo, basado en entrevistas semi-estructuradas, de 2 casos que muestran dos fenomenos didacticos de interes en la resolucion de problemas por transferencia analogica. El primero muestra un ‘efecto pantalla’, en el cual el sujeto no puede acceder a la estructura de los problemas a partir de los enunciados. En el segundo caso, el sujeto no logra alcanzar un estado estable de comprension, a pesar de su avance, y por tanto acaba por retroceder a un estado de ausencia de conflicto cognitivo, pero indeseado desde el punto de vista didactico (‘efecto Sisifo’). Se discuten las posibles implicaciones didacticas de estos casos.

Descripción del perfil metabólico de adenomas hipofisarios mediante espectroscopia "ex-vivo", por resonancia magnética de alta resolución con rotació…
2017
INTRODUCCION La técnica experimental de espectroscopia ex¬ vivo, mediante resonancia magnética de alta resolución con rotación al ángulo mágico, utilizada en el estudio de muestras intactas de tejidos biológicos, ha demostrado ser una herramienta útil para la obtención de datos relevantes acerca de su perfil metabólico. Como ejemplo, su aplicación al estudio de tumores gliales del sistema nervioso central, se ha trasladado a la clínica diaria y tiene un papel relevante en el manejo y toma de decisiones terapéuticas. Los adenomas hipofisarios son tumores frecuentes, con características biológicas que hacen de su diagnóstico y manejo una tarea compleja que requiere un abordaje multidisciplina…
Aerosolization Performance of Jet Nebulizers and Biopharmaceutical Aspects
2019
In this work, 13 jet nebulizers, some of which in different configurations, were investigated in order to identify the biopharmaceutical constraints related to the quality attributes of the medicinal products, which affect their safety, efficiency, compliance, and effectiveness. The aerosolization parameters, including the aerosol output, aerosol output rate, mass median aerodynamic diameter, and fine particle fraction, were determined according to the European Standard EN 13544-1, using sodium fluoride as a reference formulation. A comparison between the aerosol output nebulization time and the fine particle fraction displayed a correlation between the aerosol quality and the nebulization …
Expired Tidal Volume and Respiratory Rate During Postnatal Stabilization of Newborn Infants Born at Term via Cesarean Delivery
2021
Objective To retrieve evolving respiratory measures in the first minutes after birth in normal neonates born at term using a respiratory function monitor. Study design We evaluated newborn babies delivered at term via cesarean after uncomplicated pregnancies. Immediately after birth, a respiratory function monitor with an adapted flowmeter and a face mask were applied at 2, 5, and 10 minutes after birth for 90 seconds in each period. We analyzed expired and inspired tidal volume, respiratory rate (RR), percentage of leakage, and number of analyzed breaths in each individual infant's recording using a respiratory research software. Results A total of 243 infants completed the study. The fina…
La responsabilidad indirecta de los prestadores de servicios de la sociedad de la información e intermediarios a la luz del artículo 138.II de la Ley…
2016
Con el auge de internet vino aparejada la idea de que todo el contenido en la red era gratuito. La proliferación de programas de intercambio de archivos y de páginas de visionado en directo (o streaming), por citar algunos ejemplos, son prueba de ello. Los creadores de estos programas, en multitud de ocasiones, han sido demandados por la vulneración de los derechos de autor. Unas pretensiones, a la sazón, desestimadas porque estos sujetos no cometían directamente la infracción, sino los usuarios de sus servicios. La situación ha cambiado. El nuevo párrafo segundo del artículo 138 de la Ley de Propiedad Intelectual amplía la legitimación pasiva a quien induzca, coopere o se beneficie de la c…

Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Studies that have looked at the relationship between training and performance have sown that athletes must practice at lot in order to reach a high level (Côté et al., 2007; Ericsson et al., 1993; Simon & Chase, 1973), and motivation is viewed as an important factor in order to implement the required training. Through satisfaction of the basic needs of autonomy, competence and relatedness, athletes will feel self-determination and intrinsic motivation (Deci & Ryan, 1985). Furthermore, football players who spend more time promoting their own learning is often preferred over players taking less responsibility (Toering et al., 2012)…
Regulation of the HTRA2 Protease Activity by an Inhibitory Antibody-Derived Peptide Ligand and the Influence on HTRA2-Specific Protein Interaction Ne…
2021
The mitochondrial serine protease HTRA2 has many versatile biological functions ranging from being an important regulator of apoptosis to being an essential component for neuronal cell survival and mitochondrial homeostasis. Loss of HTRA2 protease function is known to cause neurodegeneration, whereas overactivation of its proteolytic function is associated with cell death and inflammation. In accordance with this, our group verified in a recent study that the synthetic peptide ASGYTFTNYGLSWVR, encoding the hypervariable sequence part of an antibody, showed a high affinity for the target protein HTRA2 and triggered neuroprotection in an in vitro organ culture model for glaucoma. To unravel t…
4812 - A0028 Gangliosides in the retina: a comparative inventory with brain and other ocular structures
2016
Purpose: Gangliosides (GG) make an extremely diverse family of glycosphingolipids particularly abundant in the brain and neural tissues. While it is known that alterations in GG metabolism are associated with visual defects, the precise biological roles of these compounds in the retina are still largely unknown. In this context, we performed an exhaustive inventory and thorough characterization of the human eye GG aiming to reveal specificities and common features of the retina compared to other ocular tissues and brain.Methods: Retina, RPE/Choroid, ciliary body, optic nerve and brain samples were collected from deceased human donors (N=7). GG were extracted and analysed by a comprehensive …
