Barbieri, M. A.; Veisaga, M. L.; Paolicchi, F.; Fornes, M. W.; Sosa, M. A.; Mayorga, L. S.; Bustos-Obregón, E.; Bertini, F. (1996)Glycosidases secreted by the epididymis become bound to the surface of spermatozoa during their transit through the epididymal duct. They are believed to play a role in mammalian fertilization. In the present report, we ...

Espinoza-Navarro, Omar; Bustos-Obregón, E. (Universidad de la Frontera, 2014)Malathion is an organophosphorous insecticide, used worldwide for pest and disease control; however, it could also affect the reproductive patterns of several species. The aim of this study was to determine the effects of ...

Montiel-Eulefi, E.; Sánchez, R.; Rojas, M.; Bustos-Obregón, E. (Universidad de la Frontera, 2009)Adult stem cells are great promise to the future of regenerative therapy, and understanding of its embryonic origin permit the discrimination of stem cell sources. Embryonic stem cells derived from inner cell mass of ...

Diaz-Fontdevila, M.; Peña, W.; Bustos-Obregón, E. (1998)The distribution of membrane filipin sterol complexes (FSC) in the plasma membrane of the acrosomal region (PMAR) of rabbit sperm from epididymis and testis, in normal and hypercholesterolaemic rabbits, was examined at ...

Penna-Videau, S.; Bustos-Obregón, E.; Cermeño-Vivas, J. R.; Chirino, D. (Universidad de la Frontera, 2012)The restriction of the mechanisms of cell proliferation in murine seminiferous epithelium, in terms of induction of programmed cell death until recently has not been fully analyzed. The aim of this work was to assess the ...

Sarabia, L.; Espinoza-Navarro, O.; Maurer, I.; Ponce, C.; Bustos-Obregón, E. (2011)Since normal sperm parameters can be altered by organophosphorous pesticides, this study intended to determine if melatonin is able to prevent the damage on sperm quality after an acute exposure to diazinon. Adult male ...

Persona, L.; Bustos-Obregón, E. (1983)The spermatogenesis of the hairy armadillo was studied. Four spermatogonial types were identified: A+ (with PAS-positive granules, presumably the stem cell). A, In. and B-similar to the situation in the rat. Spermiogenesis ...

Bustos-Obregón, E.; Holstein, A. F. (Springer-Verlag, 1976)The ultrastructure of the normal human rete testis was analyzed. The rete testis cavities are irregularly shaped and contain virtually no spermatozoa. Smooth muscle cells often surround the cavities. In the epithelial ...
