Experimental increase of worker diversity benefits brood production in ants
2021
Background The reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high genetic relatedness. However, many extant eusocial species have developed strategies that decrease genetic relatedness in their colonies, suggesting some benefits of the increased diversity. Multiple studies support this hypothesis by showing positive correlations between genetic diversity and colony fitness, as well as finding effects of experimental manipulations of diversity on colony performance. However, alternative explanations could account for most of these reports, and the benefits of diversity on performance in eusocial insects stil…
Activité physique et prévention des chutes chez les personnes âgées
2015
Les chutes chez les personnes âgées sont fréquentes : près d’une personne de plus de 65 ans sur trois et une personne de plus de 80 ans sur deux chutent chaque année. L’état de santé, les capacités fonctionnelles, les facteurs comportementaux ou les caractéristiques de l’environnement constituent autant de facteurs de risque. Au-delà des traumatismes physiques et psychologiques tels que la peur de tomber qui en résultent, les chutes peuvent entraîner des limitations fonctionnelles, une diminution de la qualité de vie, une perte d’autonomie voire une entrée en institution.Dans un contexte de vieillissement de la population, la prévention des chutes et la préservation de l’autonomie dans les …
Transnational Political Activities of the Swedish Finn Youth Organization
2017
This article looks at the Swedish Finn Youth Organization’s transnational political activities, and how they have developed. In the beginning, the youth organization modelled itself after its mother organization and joined the Finnish Expatriate Parliament (FEP), which made its participation in transnational practices easy. The case study of the Swedish Finn Youth Organization in Stockholm, Sweden, demonstrates that if the younger generation is given an opportunity to establish and govern their own associations, new forms of organization can be expected. The younger generation has distinguished itself from the older generation’s associations by cooperating with other minorities and taking m…
Nitric oxide radicals are emitted by wasp eggs to kill mold fungi
2019
Detrimental microbes caused the evolution of a great diversity of antimicrobial defenses in plants and animals. Insects developing underground seem particularly threatened. Here we show that the eggs of a solitary digger wasp, the European beewolf Philanthus triangulum, emit large amounts of gaseous nitric oxide (NO⋅) to protect themselves and their provisions, paralyzed honeybees, against mold fungi. We provide evidence that a NO-synthase (NOS) is involved in the generation of the extraordinary concentrations of nitrogen radicals in brood cells (~1500 ppm NO⋅ and its oxidation product NO2⋅). Sequencing of the beewolf NOS gene revealed no conspicuous differences to related species. However,…
Data concerning the protein absorption and retention properties of xyloglucan-based hydrogel film
2018
In wound dressing applications, exudate absorption and retention are important properties. The data presented here assess the ability of the crosslinked xyloglucan-poly(vinyl alcohol) hydrogel films (XG-PVA), described in "Xyloglucan-based hydrogel films for wound dressing: Structure-property relationships" (Ajovalasit et al., 2018) [1] and "Biocompatibility, hemocompatibility and antimicrobial properties of xyloglucan-based hydrogel film for wound healing application" (Picone et al., 2019), to absorb and retain proteins. These properties were investigated by Comassie blue staining and electrophoresis of Fetal Serum Proteins. (C) 2018 The Authors. Published by Elsevier Inc. This is an open …
El rol del gestor deportivo municipal en la Comunidad Valenciana, pasado, presente y futuro
2003
INTRODUCCIÓNLa sociedad valenciana actual se encuentra ante una nueva situación caracterizada por el ingente incremento de la demanda de actividad físico-deportiva por parte de los ciudadanos, a todo ello se le une un acelerado proceso de diferenciación de dicha demanda, generando cambios de concepción en cuanto a la relación actividad física/individuo. Así pues, hemos pasado de una óptica tradicional en virtud de la cual es el individuo el que debe someterse a la actividad físico-deportiva, a otra óptica innovadora según la cual la adaptación debe ocurrir justamente de modo inverso, la actividad físico-deportiva ha de ser diseñada en función de los deseos del ciudadano.Este es uno de los p…
