    • A high incidence of meiotic silencing of unsynapsed chromatin is not associated with substantial pachytene ... 
      Manterola, Marcia; Page, Jesús; Vasco, Chiara; Berríos, Soledad; Parra, María Teresa; Viera, Alberto; Rufas, Julio S.; Zuccotti, Maurizio; Garagna, Silvia; Fernández Donoso, Raúl (2009)
      Meiosis is a complex type of cell division that involves homologous chromosome pairing, synapsis, recombination, and segregation. When any of these processes is altered, cellular checkpoints arrest meiosis progression and ...
    • Aneuploidy in spermatids of Robertsonian (Rb) chromosome heterozygous mice 
      Manieu, Catalina; González, Marisel; López-Fenner, Julio; Page, Jesús; Ayarza, Eliana; Fernández Donoso, Raúl; Berríos, Soledad (Kluwer Academic Publishers, 2014)
      © 2014, The Author(s). Rb translocations are chromosomal rearrangements frequently found in natural populations of the house mouse Mus musculus domesticus. The standard diploid karyotype of the house mouse consisting of ...
    • Antimitochondrial antibody detection by indirect immunofluorescence on mouse sperms 
      Martínez, S.; Berríos, S.; Fernández Donoso, Raúl; Brahm, J.; Cuchacovich Turteltaub, Miguel (1996)
      Antimitochondrial antibodies (AMA) are characteristically present in the serum of patients with primary biliary cirrhosis (PBC). AMA detection constitutes an important step for the clinical diagnosis of PBC, the indirect ...
    • Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n-26 from the Vulcano ... 
      Berríos del Solar, María Soledad; Fernández Donoso, Raúl; Page, Jesús; Ayarza Ramírez, Gladys; Capanna, Ernesto; Solano, Emanuela; Castiglia, Riccardo (PAGEPress Publications, 2018)
      The size and shape of the chromosomes, as well as the chromosomal domains that compose them, are determinants in the distribution and interaction between the bivalents within the nucleus of spermatocytes in prophase I of ...
    • Model of chromosome associations in mus domesticus spermatocytes 
      Berríos, Soledad; Manterola, Marcia; Prieto, Zulita; López Fenner, Julio; Page, Jesús; Fernández Donoso, Raúl (Society of Biology of Chile, 2010)
      Understanding the spatial organization of the chromosomes in meiotic nuclei is crucial to our knowledge of the genome's functional regulation, stability and evolution. This study examined the nuclear architecture of Mus ...
    • Number and nuclear localisation of nucleoli in mammalian spermatocytes 
      Berríos, Soledad; Fernández Donoso, Raúl; Pincheira, Juana; Page, Jesús; Manterola, Marcia; Cristina Cerda, Marcia (2004)
      In seven mammalian species, including man, the position and number of nucleoli in pachytene spermatocyte nuclei were studied from electron microscope (EM) nuclear sections or bivalent microspreads. The number and position ...
    • Synaptic configuration of quadrivalents and their association with the XY bivalent in spermatocytes of ... 
      Berríos, Soledad; Fernández Donoso, Raúl; Ayarza, Eliana (2017)
      BACKGROUND: The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains and consequently is prone to modification by chromosomal rearrangements. ...
