Role of Multiple Vitamin D-Related Polymorphisms in Multiple Sclerosis Severity: Preliminary Findings
2022
Background: Multiple Sclerosis (MS) is a multifactorial disease whose pathogenesis is the result of interaction among genetic, epigenetic, and environmental factors. Among these, a role for vitamin D hypovitaminosis has emerged in recent decades. Vitamin D levels are influenced by both environmental and genetic factors. Single nucleotide polymorphisms (SNPs) in genes codifying for molecules involved in vitamin D metabolism have been associated with an increased risk of developing MS. However, few studies assessed the association of such SNPs with the severity of the disease. The aim of this observational study was to evaluate the potential association among vitamin D status, MS severity, an…
Multivariate analysis of defensive phase in football: Identification of successful behavior patterns of 2014 Brazil FIFA World Cup
2021
The aim of this study was to identify variables associated with direct recovery of the ball during defensive transitions in elite soccer and to propose a model with certain guarantees of success based on a multivariate analysis in which binary logistic regression was used to explore interaction between variables. 1,722 defensive transitions were analysed in the final stages of the FIFA World Cup 2014 in Brazil and investigated the following variables: duration of defensive transition; possession loss zone; position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, period of the match, position of defence line, zone in which the…
Structural invariants for the prediction of relative toxicities of polychloro dibenzo-p-dioxins and dibenzofurans
2004
Multivariate models are reported that can predict the relative toxicity of compounds with severe environmental impact, namely polychloro dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs). Multiple linear regression analysis (MLR) and partial least square projections of latent variables (PLS) show the usefulness of graph-theoretical descriptors, mainly topological charge indices (TCIs), in these series. The general trends of the group are correctly reproduced and better results are presented than have previously been published. In general, the more toxic compounds exhibit more symmetric molecular structures.
Trends and potential human health risk of trace elements accumulated in transplanted blue mussels during restoration activities of Flekkefjord fjord …
2022
AbstractThe monitoring of contaminants represents a priority to preserve the integrity of marine ecosystems, as well as to plan and to manage restoration activities in order to protect environmental and human health. In the present study, a 6-months active biomonitoring was performed to explore the levels of eighteen trace and toxic elements, including heavy metals (TEs; i.e. Al, As, Ca, Cd, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, P, Pb, Sr, Ti, and Zn), accumulated in soft tissues of blue mussel (Mytilus edulis Linnaeus, 1758) individuals transplanted at different depths (5- and 15-m depth) in five locations within the Flekkefjord fjord (Southern Norway). As this area suffered a long-lasting co…

Preliminary study of coach verbal behaviour according to game actions
2012
Guzman JF, Calpe-Gomez V. Preliminary study of coach verbal behaviour according to game actions. J. Hum. Sport Exerc. Vol. 7, No. 2, pp. 376-382, 2012. The aim of this study was to analyse the interaction between game actions in high-level handball and verbal behaviour performed by the coach. For this purpose, a match of the 1 st National Division of male Spanish handball was analysed. The type of behaviour and the content of the message reported by the coach were recorded using a modified version of Coaching Behaviour Assessment System (CBAS) and Coach Analysis and Intervention System (CAIS). About game actions, they were grouped into positive and negative. Statistically significant differ…

Una nación descamisada : Ortega y Gasset y su idea de España durante la Primera Guerra Mundial (1914-1918)
2015
Ortega dedicó una atención algo escasa a la Primera Guerra Mundial en sus escritos. Pero para él la guerra fue una posibilidad de pensar la posibilidad de regeneración de la nación española . Estuvo menos interesado en escoger campos entre los aliados o Alemania que en lamentar los efectos de la neutralidad para España (en 1914 como en 1918). Esta equidistancia revisable fue, además, su manera de crearse un lugar en el campo de fuerzas intelectual y en la esfera política.Ortega insistió siempre en que la neutralidad, si era fruto de la debilidad, era la peor cosa que podía sucederle a España, pues la condenaba a la periferia de la toma de decisiones internacionales. Era causa y a la vez efe…
Articular la nación. La María de Ayguals de Izco y la nacionalización española (1845-1850)
2017
Los estudios más recientes sobre el nacionalismo subrayan el carácter narrativo de las identidades nacionales y la necesidad de cuestionar los modelos teóricos elitistas de construcción nacional. En el texto parto de estas propuestas y del concepto de "articulación" de Michael Kennedy y Ronald Suny para estudiar la interacción que se produce María, la hija de un jornalero (1845-1846) de Wenceslao Ayguals de Izco. Estudio la nacionalización que lleva a cabo Ayguals de determinados lenguajes (honor, amor, religión) que eran fácilmente reconocibles por sus lectores. Posteriormente analizo las estrategias narrativas que utiliza y que pudieron contribuir a que la novela fuera leída nacionalmente…
