    Análisis del apego familiar al viajar con mascotas. Una perspectiva desde la demanda turística
    (Servicio publicaciones. Universidad de Murcia, 2023) Marmolejo Martín, Juan Antonio; Moral Cuadra, Salvador; Aguilar Rivero, Minerva; López Guzmán, Tomás
    Las mascotas en general, y los perros en particular, se han convertido en una parte importante de las familias y de su planificación de las vacaciones. En esta investigación se presentan los resultados de una investigación realizada a propietarios de perros en España para conocer sus percepciones en relación con la posibilidad de viajar con sus mascotas. La principal aplicación práctica de esta investigación radica en presentar una serie de resultados que pueden ser útiles para que los destinos que pretendan atraer a esta tipología de turistas puedan definir sus lugares como “dog friendly”.

    Extracellular vesicles in seminal fluid and effects on male reproduction. An overview in farm animals and pets
    (2022-11) Roca Aleu, Jorge; Rodríguez Martínez, Heriberto; Padilla, Lorena; Lucas, Xiomara; Barranco Cascales, Isabel; Medicina y Cirugía Animal
    Extracellular vesicles (EVs) are lipid bilayer nanovesicles released by most functional cells to body fluids, containing bioactive molecules, mainly proteins, lipids, and nucleic acids having actions at target cells. The EVs have essential functions in cell-to-cell communication by regulating different biological processes in target cells. Fluids from the male reproductive tract, including seminal plasma, contain many extracellular vesicles (sEVs), which have been evaluated to a lesser extent than those of other body fluids, particularly in farm animals and pets. Results from the few studies that have been conducted indicated epithelial cells of the testis, epididymis, ampulla of ductus deferens and many accessory sex glands release sEVs mainly via apocrine mechanisms. The sEVs are morphologically heterogeneous and bind to functional cells of the male reproductive tract, spermatozoa, and cells of the functional tissues of the female reproductive tract after mating or insemination. The sEVs encapsulate proteins and miRNAs that modulate sperm functions and male fertility. The sEVs, therefore, could be important as reproductive biomarkers in breeding sires. Many of the current findings regarding sEV functions, however, need experimental confirmation. Further studies are particularly needed to characterize both membranes and contents of sEVs, as well as the interaction between sEVs and target cells (spermatozoa and functional cells of the internal female reproductive tract). A priority for conducting these studies is development of methods that can be standardized and that are scalable, cost-effective and time-saving for isolation of different subtypes of EVs present in the entire population of sEVs.
