    El objetivo de este artículo es establecer las posibles relacionesdiacrónicas detectadas en el análisis táctico de los asaltos de esgrima deespada masculina, desde tres técnicas analíticas complementarias. Se utilizóun diseño observacional nomotético, puntual y multidimensional enel registro de ocho asaltos de dos esgrimistas finalistas en los mundialesde Budapest 2013 y Kazán 2014. Se utilizó el instrumento de observaciónESGRIMOBS. En el muestreo observacional realizado con LINCE v.1.1 seregistraron 407 frases de armas. El análisis metodológico se realizó con losprogramas THEME v.6 Edu, GSEQ5 y HOISAN. Los resultados concluyenel interés de este análisis complementario a través de dos claras orientaciones.En primer lugar, un análisis táctico (intra-frase de armas), que vinculael pensamiento táctico con la ejecución técnica específica y su eficacia.Este análisis intra-frase de armas se lleva a cabo mediante el análisis secuencialdel Retardo 0 (análisis de coocurrencias) y las configuraciones de losT-Patterns. En segundo lugar, un análisis estratégico (inter-frases de armas)que nos informa de la relación bidireccional, prospectiva y retrospectiva, delas acciones de esgrima en relación a su eficacia. Este análisis inter-frases dearmas se realiza mediante el análisis secuencial en los retardos -1 a -5 y +1a +5, las agrupaciones de clusters de los T-Patterns y el análisis de coordenadaspolares. Estas herramientas nos permiten establecer relaciones directasentre las distintas acciones tácticas y su eficacia en el marcador, así comosobre las operaciones estratégicas de los tiradores durante la competición,pudiendo constituir un excelente complemento para la mejora de la tomade decisiones de los esgrimistas

    Nuclear WRAP53 promotes neuronal survival and functional recovery after stroke

    Failure of neurons to efficiently repair DNA double-strand breaks (DSBs) contributes to cerebral damage after stroke. However, the molecular machinery that regulates DNA repair in this neurological disorder is unknown. Here, we found that DSBs in oxygen/glucose-deprived (OGD) neurons spatiotemporally correlated with the up-regulation of WRAP53 (WD40-encoding p53-antisense RNA), which translocated to the nucleus to activate the DSB repair response. Mechanistically, OGD triggered a burst in reactive oxygen species that induced both DSBs and translocation of WRAP53 to the nucleus to promote DNA repair, a pathway that was confirmed in an in vivo mouse model of stroke. Noticeably, nuclear translocation of WRAP53 occurred faster in OGD neurons expressing the Wrap53 human nonsynonymous single-nucleotide polymorphism (SNP) rs2287499 (c.202C>G). Patients carrying this SNP showed less infarct volume and better functional outcome after stroke. These results indicate that WRAP53 fosters DNA repair and neuronal survival to promote functional recovery after stroke

    Adapting football to the child: an application of the logistic regression model in observational mewthodology.

    Logistic regression is included into the analysis techniques which are valid for observationalmethodology. However, its presence at the heart of thismethodology, and more specifically in physical activity and sports studies, is scarce. With a view to highlighting the possibilities this technique offers within the scope of observational methodology applied to physical activity and sports, an application of the logistic regression model is presented. The model is applied in the context of an observational design which aims to determine, from the analysis of use of the playing area, which football discipline (7 a side football, 9 a side football or 11 a side football) is best adapted to the child"s possibilities. A multiple logistic regression model can provide an effective prognosis regarding the probability of a move being successful (reaching the opposing goal area) depending on the sector in which the move commenced and the football discipline which is being played
