PublicationOpen AccessLa presencia de marcas de moda en prime time. La Revuelta de TVE(2025-06-20) Fernández Rincón, Antonio Raúl; Hernández Gómez, Onésimo Samuel; Comunicación; Facultad de Comunicación y DocumentaciónIntroducción: La colaboración o emplazamiento de marcas en contenidos audiovisuales y la contratación de celebridades (influencers) como prescriptores no son técnicas nuevas, pero han obtenido un nuevo impulso en la sociedad digital y especialmente en ámbitos restringidos a la publicidad convencional. Analizamos la presencia de marcas de moda como colaboradoras de La Revuelta, uno de los programas de televisión con mayor audiencia en España. Metodología: Estudiamos los primeros 58 programas emitidos en 2024 a través de un análisis de contenido para descubrir las características de estas marcas, su tiempo y forma de inserción, así como las conexiones con los contenidos, personajes e invitados. Resultados: Entre las marcas de moda que colaboran con el programa encontramos una convivencia entre firmas de pequeño tamaño, alineadas preferentemente con el estilo juvenil y urbano, con grandes marcas multinacionales productoras de material deportivo. Discusión: En el formato colaboración la presencia de la marca en pantalla no está mediada por una contraprestación económica pero sí puede dar lugar a una notoriedad similar. Es un recurso que puede resultar muy apropiado para marcas independientes, de pequeño tamaño o emergentes. Esta vía alternativa a la publicidad o al emplazamiento convencional les permite competir en igualdad de condiciones llegando a audiencias masivas. Conclusiones: La asociación de marcas a los diferentes personajes que aparecen en el programa no es casual, sino que parece responder a un criterio de afinidad entre las marcas y el carácter y/o personalidad de estos.- PublicationOpen AccessEvaluation of three Immunochromatographic Assays for detection of Legionella pneumophila serogroup 1 Antigen in Urine Samples(Sociedad Española de Quimioterapia, 2009) M.J. Muñoz,; M.C. Martínez Toldos; G. Yagüe; M. Segovia; Genética y MicrobiologíaThe Uni-Gold, the SAS and the Binax NOW immunochro matographic test (ICT) urinary antigen assays for the qualitative detection of Legionella pneumophila serogroup 1 were com pared using 39 unfrozen and nonconcentrated urine samples from patients with Legionnaires´ disease (LD). The Uni-Gold antigen test detected the urinary antigen in 41% (16/39), the SAS antigen test in 61.5% (24/39), and the Binax NOW antigen test in 74.3% (29/39). The Binax NOW ICT assay showed the best results when detecting L. pneumophila urinary antigen.

- PublicationOpen AccessEffect of Superovulation Treatment on Oocyte's DNA Methylation(MDPI, 2022-12-18) S. Lopes, Jordana; Ivanova, Elena; Ruiz, Salvador; Andrews, Simon; Kelsey, Gavin; Coy, Pilar; Didáctica y Organización EscolarControlled ovarian stimulation is a necessary step in some assisted reproductive procedures allowing a higher collection of female gametes. However, consequences of this stimulation for the gamete or the offspring have been shown in several mammals. Most studies used comparisons between oocytes from different donors, which may contribute to different responses. In this work, we use the bovine model in which each animal serves as its own control. DNA methylation profiles were obtained by single-cell whole-genome bisulfite sequencing of oocytes from pre-ovulatory unstimulated follicles compared to oocytes from stimulated follicles. Results show that the global percentage of methylation was similar between groups, but the percentage of methylation was lower for non-stimulated oocytes in the imprinted genes APEG3, MEG3, and MEG9 and higher in TSSC4 when compared to stimulated oocytes. Differences were also found in CGI of imprinted genes: higher methylation was found among non-stimulated oocytes in MEST (PEG1), IGF2R, GNAS (SCG6), KvDMR1 ICR UMD, and IGF2. In another region around IGF2, the methylation percentage was lower for non-stimulated oocytes when compared to stimulated oocytes. Data drawn from this study might help to understand the molecular reasons for the appearance of certain syndromes in assisted reproductive technologies-derived offspring.
- PublicationOpen AccessYear-Long Phenotypical Study of Calves Derived From Different Assisted-Reproduction Technologies(Frontiers Media, 2022-01-10) Lopes, Jordana S.; Soriano-Úbeda, Cristina; Navarro-Serna, Sergio; París-Oller, Evelyne; Canha-Gouveia, Analuce; Sarrias-Gil, Lucía; Cerón, José Joaquin; CoY, Pilar; Didáctica y Organización EscolarAssisted reproductive technologies play a major role in thecattle industry. An increasein the use ofin vitro-derived embryos is currently being seen around the globe. But theefficiency and quality of thein vitro-derived embryos are substandard when comparedto thein vivoproduction. Different protocols have been designed to overcome this issue,one of those being the use of reproductive fluids as supplementation to embryo culturemedia. In this study,in vitro-derived calves produced with reproductive fluids added totheir embryo production protocol were followed for the firstyear of life pairwise withtheirin vivocontrol, produced by artificial insemination (AI), and theirin vitrocontrol,produced with standard supplementation in embryo production. The objective was toassess if any differences could be found in terms of growth and development as well ashematological and biochemical analytes between the different systems. All the analysedvariables (physical, hematological, and biochemical) were within physiological range andvery similar between calves throughout the entire experiment. However, differences weremore evident between calves derived from standardin vitroproduction and AI. Weconcluded that the use of reproductive fluids as a supplementation to the embryo culturemedia results in calves with closer growth and development patterns to those born byAI than the use of bovine serum albumin as supplementation.
