  • Exploring Omega-3′s impact on the expression of Bone-Related Genes in Meagre (Argyrosomus regius)
    Publication . Luján-Amoraga, Leticia; Delgado-Martín, Belén; Lourenço-Marques, Cátia; J. Gavaia, Paulo; Bravo, Jimena; Bandarra, Narcisa M.; Dominguez, David; Izquierdo, Marisol S.; Pousão-Ferreira, Pedro; Ribeiro, Laura
    Dietary supplementation with Omega-3 fatty acids seems to promote skeletal health. Therefore, their consumption at imbalanced or excessive levels has offered less beneficial or even prejudicial effects. Fish produced in aquaculture regimes are prone to develop abnormal skeletons. Although larval cultures are usually fed with diets supplemented with Omega-3 Long Chain Polyunsaturated fatty acids (LC-PUFAs), the lack of knowledge about the optimal requirements for fatty acids or about their impact on mechanisms that regulate skeletal development has impeded the design of diets that could improve bone formation during larval stages when the majority of skeletal anomalies appear. In this study, Argyrosomus regius larvae were fed different levels of Omega-3s (2.6% and 3.6% DW on diet) compared to a commercial diet. At 28 days after hatching (DAH), their transcriptomes were analyzed to study the modulation exerted in gene expression dynamics during larval development and identify impacted genes that can contribute to skeletal formation. Mainly, both levels of supplementation modulated bone-cell proliferation, the synthesis of bone components such as the extracellular matrix, and molecules involved in the interaction and signaling between bone components or in important cellular processes. The 2.6% level impacted several genes related to cartilage development, denoting a special impact on endochondral ossification, delaying this process. However, the 3.6% level seemed to accelerate this process by enhancing skeletal development. These results offered important insights into the impact of dietary Omega-3 LC-PUFAs on genes involved in the main molecular mechanism and cellular processes involved in skeletal development.

  • Inteligencia artificial en la comunicación deportiva del deporte profesional: el caso de la segunda división española de fútbol
    Publication . Guerrero Navarro, Daniel; García Verdugo, Victoria; Gil, Francisco Baptista; Alves, Paulo
    La tecnología está inmersa en nuestra rutina social y actualmente hemos visto la irrupción de conceptos como el metaverso o los chatbots, con una tendencia creciente para la sociedad futura. La comunicación se ve afectada por toda esta revolución, tanto positiva como negativamente: hay tareas que, en apariencia, pueden ser elaboradas por la inteligencia artificial (IA), readaptando el futuro de ciertas áreas de trabajo. Este trabajo se centra en cómo los equipos de categoría profesional del fútbol español se están adaptando a los citados cambios, como categoría de élite de la industria deportiva. Se ha entrevistado a los responsables de los departamentos de comunicación de las entidades que compiten en La Liga durante la temporada 2022/23. La muestra obtenida de once equipos ha permitido conocer los servicios utilizados, las estrategias destacadas por los profesionales y las preocupaciones alrededor del oficio. Los responsables de comunicación de los clubes de manera mayoritaria están utilizando las herramientas de inteligencia artificial, pero no temen perder su puesto de trabajo por la futura implantación de dicha tecnología en su ámbito profesional.
