Quantification and viability assays of Toxoplasma gondii in commercial "Serrano" ham samples using magnetic capture real-time qPCR and bioassay techn…
2014
"Serrano" ham is a typical pork product from the Mediterranean area, highly valued for its flavour. To make Serrano ham, pork undergoes a salting and a subsequent fermentation process known as curing. Certain pigs used for meat production are an important source of Toxoplasma gondii infection in humans. We have developed a method for quantifying and assaying the viability of the T. gondii present in commercial Serrano ham samples. A magnetic capture method for the isolation of T. gondii DNA and a qRT-PCR were used to estimate the T. gondii burden in 475 commercial samples of "Serrano" ham in two presentation formats: ham pieces and sliced ham. The infectivity capacity of T. gondii in positi…
Contactus adherens, a special type of plaque-bearing adhering junction containing M-cadherin, in the granule cell layer of the cerebellar glomerulus.
1995
In the glomeruli of the granule cell layer of mammalian cerebellum, neuronal extensions are interconnected by numerous small, nearly isodiametric (diameters up to 0.1 micron), junctions previously classified as puncta adherentia related to the vinculin-containing, actin microfilament-anchoring junctions of the zonula adherens of epithelial and certain other cells. Using immunofluorescence and immunoelectron microscopy, we have found, however, that these junctions are negative for E- and VE-cadherin, for desmosomal cadherins, and also for vinculin, alpha-actinin, and desmoplakin, but they do contain, in addition to the protein plakoglobin common to all forms of adhering junctions, the plaque…
Els mecanismes de socialització virtual
2012
L'objectiu de l'article és confirmar l'activació, en els entorns virtuals, dels mecanismes de socialització estudiats en contextos presencials. La troballa de 21 mecanismes de socialització és una de les aportacions teòriques. L'estudi de la socialització virtual necessita un disseny mitjançant una estratègia multimètode i aproximacions micro i macrosociológica, amb tècniques com: anàlisi de xarxes socials, cas únic del grup virtual, tècnica Delphi, etnografia virtual i anàlisi de contingut. Finalment, la verificació dels mecanismes de socialització en línia: identificació, adaptació, aprenentatge social, internalització i assimilació, semblen els més apropiats per al treball en l'ensenyame…
Análise dos novos anglicismos léxicos na língua espanhola no contexto das obras e corpus acadêmico digital
2020
Resumen Con la llegada del siglo XXI, las obras académicas en español empezaron a mostrar un mayor interés por el anglicismo léxico, reflejando así el uso generalizado que sociedad y medios de comunicación hacían de él. Paralelamente, la accesibilidad que supone la digitalización de corpus académicos, como el CREA y el CORPES XXI de la Real Academia Española, permite investigar la progresión de estas voces en los textos que los componen. Durante los últimos años, estos anglicismos se han ajustado a las necesidades de la lengua española tanto en España como en América, bien incorporando términos, bien adaptándolos o bien rechazando aquellos que se consideraban ya inservibles. A partir de est…
Assessment and inter-comparison of recently developed/reprocessed microwave satellite soil moisture products using ISMN ground-based measurements
2019
Soil moisture (SM) is a key state variable in understanding the climate system through its control on the land surface energy, water budget partitioning, and the carbon cycle. Monitoring SM at regional scale has become possible thanks to microwave remote sensing. In the past two decades, several satellites were launched carrying on board either radiometer (passive) or radar (active) or both sensors in different frequency bands with various spatial and temporal resolutions. Soil moisture algorithms are in rapid development and their improvements/revisions are ongoing. The latest SM retrieval products and versions of products that have been recently released are not yet, to our knowledge, com…
La Vinculación Ciencia-Sociedad: Estereotipos y Nuevos Enfoques
2016
[ES]: La importancia social de la ciencia ha evolucionado notablemente desde mediados del siglo XX, dando lugar a un cambio en el enfoque y desarrollo de la actividad científica. En este contexto, se ha producido un aumento notable de los estudios que analizan en profundidad los procesos de intercambio y transferencia de conocimiento que se producen entre los investigadores y los agentes sociales, en gran medida para su promoción desde las políticas científicas e institucionales. Este artículo describe la evolución de los enfoques sobre las relaciones ciencia-sociedad y analiza los principales elementos de los procesos de intercambio y transferencia de conocimiento mediante un estudio empír…

Los terremotos de 1748 en el antiguo Reino de Valencia: Documentos de base y notas para su estudio
1988
SUCESO CATASTROFICO DE PRIMER ORDEN, LOS TERREMOTOS VALENCIANOS DE 1748 SE CONSTITUYEN EN ANTECEDENTE DIRECTO DE LOS QUE ASOLARON LISBOA EN 1755. A PESAR DE SER MENOS CONOCIDOS QUE ESTOS, POSIBLEMENTE PORQUE NO AFECTARON A GRANDES NUCLEOS DE POBLACION Y SI A COMARCAS INTERIORES, SU IMPACTO DEJO UN GRAN NUMERO DE ESCRITOS, DESCONOCIDOS EN SU MAYOR PARTE. AQUI SE PRESENTAN ACOMPAÑADOS DE SU LOCALIZACION ACTUAL Y DE UNAS NOTAS MINIMAS QUE SIRVEN PARA CARACTERIZAR LOS TEMBLORES EN EL CONJUNTO DE LAS TEORIAS SISMOGENICAS DEL SIGLO XVIII. (A)
Thiosulfate Reduction in Salmonella enterica Is Driven by the Proton Motive Force
2012
ABSTRACT Thiosulfate respiration in Salmonella enterica serovar Typhimurium is catalyzed by the membrane-bound enzyme thiosulfate reductase. Experiments with quinone biosynthesis mutants show that menaquinol is the sole electron donor to thiosulfate reductase. However, the reduction of thiosulfate by menaquinol is highly endergonic under standard conditions (Δ E °′ = −328 mV). Thiosulfate reductase activity was found to depend on the proton motive force (PMF) across the cytoplasmic membrane. A structural model for thiosulfate reductase suggests that the PMF drives endergonic electron flow within the enzyme by a reverse loop mechanism. Thiosulfate reductase was able to catalyze the combined …
Desmosomes: interconnected calcium-dependent structures of remarkable stability with significant integral membrane protein turnover
2002
Desmosomes are prominent cell adhesion structures that are major stabilizing elements, together with the attached cytoskeletal intermediate filament network, of the cytokeratin type in epithelial tissues. To examine desmosome dynamics in tightly coupled cells and in situations of decreased adhesion, fluorescent desmosomal cadherin desmocollin 2a (Dsc2a) chimeras were stably expressed in human hepatocellular carcinoma-derived PLC cells (clone PDc-13) and in Madin-Darby canine kidney cells (clone MDc-2) for the continuous monitoring of desmosomes in living cells. The hybrid polypeptides integrated specifically and without disturbance into normal-appearing desmosomes that occurred in associati…
