Borie Polanco, Consuelo; Cepeda, Raquel; Villarroel, M.; Reyes Solovera, Mónica de los (UNIVERSIDAD AUSTRAL CHILE, FACULTAD CIENCIAS VETERINARIAS, 2002)Seminal and histological reproductive characteristics in three Brucella canis seropositive dogs are described. Seminal volume and sperm morphology were altered and no sperm was seen in one dog. This agrees with histological ...

Fernández, Tomás; Palomino Mackenney, Jaime; Parraguez Gamboa, Víctor; Peralta Troncoso, Óscar; Reyes Solovera, Mónica de los (Elsevier, 2016)Growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) playimportant functions in follicular and oocyte development in many species. This study eval-uated the dynamic expression of GDF-9 and ...

Parraguez Gamboa, Víctor; Mamani, Sandra; Cofre, Eileen; Castellaro, Giorgio; Urquieta Mangiola, Bessie; Reyes Solovera, Mónica de los; Astiz, Susana; González Bulnes, Antonio (Public Library of Science, 2015)Pregnancies at high-altitudes are influenced by hypoxia and oxidative stress and frequently affected by IUGR. However, a common thought is that early pregnant women visiting altitude have no major complications for gestation ...

Palomino Mackenney, Jaime; Flores Becerra, Javiera; Ramírez Saboya, Georges; Parraguez Gamboa, Víctor; Reyes Solovera, Mónica de los (MDPI, 2021)The oestrous cycle in canines is specifically more extended than that in other mammals. This implies that the oocytes do not reach maturity within the ovarian follicle but undergo final maturation in the oviducts. Besides ...

Parraguez Gamboa, Víctor; Urquieta, Bessie; Pérez, Laura; Castellaro Galdames, Giorgio; Reyes Solovera, Mónica de los; Torres Rovira, Laura; Aguado Martínez, Adriana; Astiz, Susana; González Bulnes, Antonio (BioMed Central, 2013-03-23)At high altitudes, hypoxia, oxidative stress or both compromise sheep fertility. In the present work, we tested the relative effect of short- or long-term exposure to high altitude hypobaric hypoxia and oxidative stress on ...

Ramírez, George; Palomino Mackenney, Jaime; Aspée Mallanes, Karla; Reyes Solovera, Mónica de los (MDPI, 2020)Simple Summary The knowledge of physiological events associated with canine reproduction involving oocyte developmental potential is essential to increase the success of reproductive biotechnologies in this species. In ...

Reyes Solovera, Mónica de los; Palomino Mackenney, Jaime; Gallegos, Carola; Espinoza, Roberto; Dettleff Faúndes, Phillipe; Peralta Troncoso, Óscar; Parraguez Gamboa, Víctor; Ramírez, George (CSIRO, 2020)The aim of this study was to evaluate the expression of connexin (Cx) 37 and Cx43 in canine cumulus-oocyte complexes (COCs) during the oestrous cycle. Cx localisation was analysed by immunohistochemistry and immunofluorescence, ...

Frey G., Walter von; Vidal M., Ricardo; Santa María S., Alejandro; Reyes Solovera, Mónica de los (Universidad de Chile, Facultad de Ciencias Veterinarias y Pecuarias, 1988)Se estudió el comportamiento de la penetración espermática en mucus cervical bovino y su relación con algunas características seminales en tres sistemas de descongelación de semen. Para ello se utilizó mucus bovino ...

Parraguez Gamboa, Víctor; Sales, Francisco; Peralta Troncoso, Óscar; Narbona Narbona, Eileen; Lira, Raúl; Reyes Solovera, Mónica de los; González Bulnes, Antonio (MDPI, 2020)Simple Summary In twin-bearing ewes, undernourishment during pregnancy lowers the birth weight and increases morbidity and mortality of lambs. One of the causes is oxidative stress, which can be prevented by supplementing ...

Sánchez, Alfonso; Reyes Solovera, Mónica de los (UNIV ZULIA, FACULTAD CIENCIAS VETERINARIAS, 2004-10)Zona pellucida (ZP) is an extracellular matrix surrounding the mammalian oocyte. In most mammalian species this matrix consists of three families of glycoproteins likely to suffer several postraductional modifications to ...
