Col·laboració 2.0: El futur de la divulgació científica
2013
La divulgació científica ha d’afrontar un nou escenari on l’escassetat d’informació ha estat substituïda per l’abundància d’informació, que a més comença a ser generalment gratuïta i produïda per aficionats i, en alguns casos, amb la mateixa o superior qualitat que la professional. Sembla imposar-se, en conseqüència, una col·laboració entre l’àmbit professional i l’aficionat, àmbits separats per una línia divisòria que ja s’ha desdibuixat.

Estudiantes de Música del Máster de Profesor de Educación Secundaria: creencias, expectativas y valoración de la distribución de créditos
2021
En este estudio cuantitativo de carácter descriptivo se investigan las creencias de 31 estudiantes de la especialidad de Música del Máster de Profesor de Educación Secundaria de la Universitat de València, sus expectativas al cursar este tipo de formación, su valoración de la distribución de los créditos de las asignaturas que lo conforman y diferencias en base al género. Los resultados presentan sus consideraciones para realizar este Máster, su opinión sobre la función docente, la metodología y contenidos que desarrollarán en futuras clases, las expectativas y la valoración de los créditos de las asignaturas del Máster, entre otros.
Inhibition of the myosin light chain kinase prevents hypoxia-induced blood-brain barrier disruption
2007
Increased mortality after stroke is associated with development of brain edema. The aim of the present study was to examine the contribution of endothelial myosin light chain (MLC) phosphorylation to hypoxia-induced blood-brain barrier (BBB) opening. Measurements of trans-endothelial electrical resistance (TEER) were performed to analyse BBB integrity in an in vitro co-culture model (bovine brain microvascular endothelial cells (BEC) and rat astrocytes). Brain fluid content was analysed in rats after stroke induction using a two-vein occlusion model. Dihydroethidium was used to monitor intracellular generation of reactive oxygen species (ROS) in BEC. MLC phosphorylation was detected using i…

Expectations, experiences and attitudes of patients and primary care health professionals regarding online psychotherapeutic interventions for depres…
2013
Abstract Background In the year 2020, depression will cause the second highest amount of disability worldwide. One quarter of the population will suffer from depression symptoms at some point in their lives. Mental health services in Western countries are overburdened. Therefore, cost-effective interventions that do not involve mental health services, such as online psychotherapy programs, have been proposed. These programs demonstrate satisfactory outcomes, but the completion rate for patients is low. Health professionals’ attitudes towards this type of psychotherapy are more negative than the attitudes of depressed patients themselves. The aim of this study is to describe the profile of d…

Ethanol cycle in an ethanologenic bacterium
2002
AbstractA novel redox cycle is suggested, performing interconversion between acetaldehyde and ethanol in aerobically growing ethanologenic bacterium Zymomonas mobilis. It is formed by the two alcohol dehydrogenase (ADH) isoenzymes simultaneously catalyzing opposite reactions. ADH I is catalyzing acetaldehyde reduction. The local reactant ratio at its active site probably is shifted towards ethanol synthesis due to direct channeling of NADH from glycolysis. ADH II is oxidizing ethanol. The net result of the cycle operation is NADH shuttling from glycolysis to the membrane respiratory chain, and ensuring flexible distribution of reducing equivalents between the ADH reaction and respiration.
β-Aminobutyric Acid Primes an NADPH Oxidase–Dependent Reactive Oxygen Species Production During Grapevine-Triggered Immunity
2010
International audience; The molecular mechanisms underlying the process of priming are poorly understood. In the present study, we investigated the early signaling events triggered by β-aminobutyric acid (BABA), a well-known priming-mediated plant resistance inducer. Our results indicate that, in contrast to oligogalacturonides (OG), BABA does not elicit typical defense-related early signaling events nor defense-gene expression in grapevine. However, in OG-elicited cells pretreated with BABA, production of reactive oxygen species (ROS) and expression of the respiratory-burst oxidase homolog RbohD gene were primed. In response to the causal agent of downy mildew Plasmopara viticola, a strong…

Intracellular acid stress inhibits plant growth by unknown mechanisms and it occurs in acidic soils and as consequence of other stresses. In order to identify mechanisms of acid toxicity, we screened activation-tagging lines of Arabidopsis thaliana for tolerance to intracellular acidification induced by organic acids. A dominant mutant, sbt4.13-1D, was isolated twice and shown to over-express subtilase SBT4.13, a protease secreted into endoplasmic reticulum. Activity measurements and immuno-detection indicate that the mutant contains less plasma membrane H+-ATPase (PMA) than wild type, explaining the small size, electrical depolarization and decreased cytosolic pH of the mutant but not orga…
