Biotécnicas reproductivas en la especie porcina: pasado, presente y futuro
Marinone, Ana Ines; Kaiser, German Gustavo; Hozbor, Federico Andres; Mucci, Nicolas Crescencio (2018-08)Argentina posee condiciones agroecológicas y sanitarias ideales para la producción de cerdos. Hasta 1990, la producción porcina en Argentina era realizada como actividad secundaria dentro de la explotación agropecuaria. ... -
Changes in the aerobic vaginal flora after treatment with different intravaginal devices in ewes
Manes, Jorgelina; Fiorentino, María Andrea; Kaiser, German Gustavo; Hozbor, Federico Andres; Alberio, Ricardo; Sánchez, Esteban O.; Paolicchi, Fernando (Elsevier, 2010-11)The objective of this study was to characterize the vaginal bacterial flora and subsequent pregnancy rates after AI in sheep subjected to 4 different estrous synchronization regimes – the use of two intravaginal devices ... -
Combined epidermal growth factor and hyaluronic acid supplementation of in vitro maturation medium and its impact on bovine oocyte proteome and competence
Rios, Glenda Laura; Buschiazzo, Jorgelina; Mucci, Nicolas Crescencio; Kaiser, German Gustavo; Cesari, Andreina; Alberio, Ricardo (Elsevier, 2015-03-15)The conditions for in vitro oocyte maturation impact on cytoplasmic and nuclear processes in the oocyte. These events are differentially influenced by the nature of the maturation inducer and the presence of intact cumulus ... -
Detection of recombinant human lactoferrin and lysozyme produced in a bitransgenic cow
Kaiser, German Gustavo; Mucci, Nicolas Crescencio; Gonzalez, Vega; Sánchez, Lourdes; Parrón, José Antonio; Pérez, María Dolores; Calvo, Miguel; Aller Atucha, Juan Florencio; Hozbor, Federico Andres; Mutto, Adrián Angel (2017-03)Lactoferrin and lysozyme are 2 glycoproteins with great antimicrobial activity, being part of the nonspecific defensive system of human milk, though their use in commercial products is difficult because human milk is ... -
Effect of Bovine Viral Diarrhea Virus on the ovarian functionality and in vitro reproductive performance of persistently infected heifers
González Altamiranda, Erika Analía; Kaiser, German Gustavo; Mucci, Nicolas Crescencio; Verna, Andrea Elizabeth; Campero, Carlos Manuel; Odeon, Anselmo Carlos (Elsevier, 2013-08-30)The aim of this study was to study the effect of Bovine Viral Diarrhea Virus on the reproductive female tract by means of analyzing the ovarian follicular population of persistently infected (PI) heifers, and evaluating ... -
Expression profile of genes as indicators of developmental competence and quality of in vitro fertilization and somatic cell nuclear transfer bovine embryos
Cánepa, María Jesús; Ortega, Nicolás Matías; Monteleone, Melisa Carolina; Mucci, Nicolas Crescencio; Kaiser, German Gustavo; Brocco, Marcela Adriana; Mutto, Adrián Angel (Plos One, 2014-09)Reproductive biotechnologies such as in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) enable improved reproductive efficiency of animals. However, the birth rate of in vitro-derived embryos still lags ... -
Improve intra‐uterine insemination in rabbits using ultra‐high temperature skim milk as extender to keep semen at room temperature
Hozbor, Federico Andres; Ledesma, Alba; Manes, Jorgelina; Rios, Glenda Laura; Kaiser, German Gustavo; Cano, Adriana Virginia; Luciano, Cecilia Ines; Alberio, Ricardo (Wiley, 2016-03)Two experiments were carried out to examine in vitro quality and in vivo fertility of rabbit semen diluted in ultra‐high temperature (UHT) skim milk. In the first experiment, pooled ejaculates of 10 adult rabbits were ... -
Interaction of bovine viral diarrhea virus with bovine cumulus–oocyte complex during IVM: Detection in permissive cells
González Altamiranda, Erika Analía; Kaiser, German Gustavo; Rios, Glenda Laura; Leunda, Maria Rosa; Odeon, Anselmo Carlos (Elsevier, 2016-11)Structural changes in the zona pellucida (ZP) of bovine oocytes seem to modulate their interaction with various viral agents, facilitating the viral infection in in vitro production systems. To evaluate the susceptibility ... -
RNA-seq analysis of single bovine blastocysts
Chitwood, James L.; Rincon, Gonzalo; Kaiser, German Gustavo; Medrano, Juan F.; Ross, Pablo J. (BMC, 2013-05)Background: Use of RNA-Seq presents unique benefits in terms of gene expression analysis because of its wide dynamic range and ability to identify functional sequence variants. This technology provides the opportunity to ... -
El rol de las biotécnicas de reproducción asistida en la transmisión del virus de la diarrea viral bovina
González Altamiranda, Erika Analía; Kaiser, German Gustavo; Odeon, Anselmo Carlos (Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2015-06)Las biotécnicas de reproducción asistida han adquirido importancia comercial en los últimos años. Asociado a estas técnicas surge el interrogante sobre su rol en la posible transmisión de agentes infecciosos vía semen y ... -
Upregulation of interferon-alpha gene in bovine embryos produced in vitro in response to experimental infection with noncytophatic bovine-viral-diarrhea virus
González Altamiranda, Erika; Arias, María E.; Kaiser, German Gustavo; Mucci, Nicolas Crescencio; Odeon, Anselmo Carlos; Felmer, Ricardo N. (Springer, 2020-11)In-vitro fertilization is a routine livestock-breeding technique widely used around the world. Several studies have reported the interaction of bovine viral-diarrhea virus (BVDV) with gametes and in-vitro-produced (IVP) ...
