Brewer's spent grains as biofuels in combustion-based energy recovery processes: Evaluation of thermo-oxidative decomposition
2022
[EN] The high global generation of wastes and side streams from agri-food production has led to environmental impact and causes nature degradation due to their uncontrolled management. These wastes are profitable materials with significant economic value that could otherwise be exploited as new sources in the feed industry or the production of bioenergy. Among them, brewer¿s spent grain (BSG) is a solid by-product generated in the beerbrewing process that consists of the barley grain husks together with parts of the pericarp and seed coat layer. Although it is rich in fibres and proteins, its main use is currently limited to animal feed or simply deposition to landfills. This study pursues …
El SIDA como enfermedad social: análisis de su presencia e investigación
2005
Jose.R.Bueno@uv.es Amparo.Madrigal@uv.es francisco.j.mestre@uv.es Al objeto de analizar aquellos elementos psicosociales que definen la difusión del VIH/SIDA, la Unidad de Investigación coordinada por el Profesor José R. Bueno Abad de la Facultad de Ciencias Sociales de la Universidad de Valencia ha puesto en marcha una investigación que tiene como objetivo fundamental la detección y análisis de las representaciones sociales del VIH. A continuación se exponen algunos de los aspectos básicos de la enfermedad, su curso y tratamiento, revelados en las fases iniciales de recogida de datos de nuestra investigación a partir de numerosas investigaciones realizadas hasta la actualidad, el rastreo d…
Pathogenesis and molecular mechanisms of anderson–fabry disease and possible new molecular addressed therapeutic strategies
2021
Anderson–Fabry disease (AFD) is a rare disease with an incidenceof approximately 1:117,000 male births. Lysosomal accumulation of globotriaosylceramide (Gb3) is the element characterizing Fabry disease due to a hereditary deficiency α-galactosidase A (GLA) enzyme. The accumulation of Gb3 causes lysosomal dysfunction that compromises cell signaling pathways. Deposition of sphingolipids occurs in the autonomic nervous system, dorsal root ganglia, kidney epithelial cells, vascular system cells, and myocardial cells, resulting in organ failure. This manuscript will review the molecular pathogenetic pathways involved in Anderson–Fabry disease and in its organ damage. Some studies reported that i…

Periodicidad y movilidad del comercio: Mercados y ferias valencianos a mediados del siglo XIX
1990
El objetivo de este artículo es analizar la localización y características de los mercados y ferias valencianos de mediados del siglo XIX en función de la teoría económica que explica la periodicidad y movilidad del comercio y la secuencia evolutiva de formación de un comercio estable. El estudio realizado demuestra que existe una estrecha relación entre la organización comercial comarcal y la densidad de población, la estructura de asentamientos y la accesibilidad a las principales corrientes comerciales interregionales, Por otra parte, la localización de las ferias está en función de la existencia de límites entre regiones económicas complementarias, cambios de pendiente y puntos de ruptu…
Connecting the data landscape of long-term ecological studies: the SPI-Birds data hub
2021
The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long-term studies of individually marked animals are not an exception. These studies are especially important as instrumental for understanding evolutionary and eco-logical processes in the wild. Furthermore, their number and global distribution provides a unique opportunity to assess the generality of patterns and to address broad-scale global issues (e.g. climate change).
Desajuste de trayectorias estudiantiles : caso comparativo de la Universidad Federal de Paraíba y la Universidad de València
2021
Este artículo aborda la cuestión del ajuste académico en las trayectorias universitarias entendiéndolo en base al ritmo de renovación de los estudiantes y de idoneidad de su rendimiento académico. El objetivo planteado es calibrar el ajuste entre ambos indicadores de rendimiento, es decir, renovación e idoneidad para poder proponer una medida integral de ajuste. Proponemos una metodología para ponderar el grado de ajuste en las trayectorias universitarias a partir de los indicadores de renovación e idoneidad mediante la propuesta de un nuevo indicador que denominamos tasa de ajuste. El procedimiento de su cálculo es a través de la adaptación del habitual índice de Gini y cuenta con la carac…
Evaluación de las células de la blastema de aleta caudal como donantes en quimeras intraespecíficas de pez cebra
2008
The blastema is a regenerative tissue with remarkable pluripotency. The aim of this work done on zebrafish (Danio rerio) was to define technical procedures required for obtaining and integrating blastema cells into embryos at the mid blastula transition stage (MBT) and the effect on survival, as well as the capacity to produce pigmented chimaeras. Wild type blastema cells were injected into gold type MBT embryos (E). Wild MBT blastomere cells were also injected into gold type MBT embryos as a control (C1). A second control group, C2, was not subjected to any manipulation. Survival was evaluated at 24, 48 and 72 h after performing the chimaerism, and the rate of adult chimaeras evaluated. Th…
Performance of industrial strains of Saccharomyces cerevisae during wine fermentation is affected by manipulation strategies based on sporulation.
2002
Genetic manipulation of industrial wine yeast strains has become an essential tool for both the study of the molecular mechanisms underlaying their physiology and the improvement of their fermentative properties. The construction of null mutants for any gene in these usually diploid strains, by using a procedure based on sporulation of a heterozygote lacking one copy of the gene of interest, has been tested as an alternative to the tedious work of sequential disruption of the complete set of copies. Our results indicate that most of the homozygotes resulting from sporulation of wine yeast strains are defective in glucose consumption under microvinification conditions in synthetic must and p…
Trx2p-dependent Regulation of Saccharomyces cerevisiae Oxidative Stress Response by the Skn7p Transcription Factor under Respiring Conditions
2013
The whole genome analysis has demonstrated that wine yeasts undergo changes in promoter regions and variations in gene copy number, which make them different to lab strains and help them better adapt to stressful conditions during winemaking, where oxidative stress plays a critical role. Since cytoplasmic thioredoxin II, a small protein with thiol-disulphide oxidoreductase activity, has been seen to perform important functions under biomass propagation conditions of wine yeasts, we studied the involvement of Trx2p in the molecular regulation of the oxidative stress transcriptional response on these strains. In this study, we analyzed the expression levels of several oxidative stress-related…
