.Desarrollo de un modelo de inteligencia artificial basado en Machine Learning para optimizar la selección embrionaria en reproducción humana asistida

Salvo Jiménez, Aitana Eugenia (Universitat Politècnica de València, 2023-07-25)

[ES] En las clínicas de reproducción asistida, tanto en el ámbito humano como animal, uno de los pasos fundamentales es la selección del embrión cultivado de mayor calidad para su posterior transferencia al útero de la ...
A 3D-Printed Large Holding Capacity Device for Minimum Volume Cooling Vitrification of Embryos in Prolific Livestock Species

Marco-Jiménez, Francisco; Garcia-Dominguez, Ximo; García-Valero, Luis; Vicente Antón, José Salvador (MDPI AG, 2023-03)

[EN] Although many devices have been developed to reduce sample volume, with an explosion of methods appearing in the literature over the last decade, commercially available devices with simultaneous vitrification of a ...
Calcium concentration in vitrification medium affects the developmental competence of in vitro matured ovine oocytes

Succu, Sara; Berlinguer, Fiammetta; Leoni, Giovanni G.; Bebbere, Daniela; Satta, Valentina; Marco Jiménez, Francisco; Pasciu, Valeria; Naitana, Salvatore (Elsevier, 2011-03-01)

[EN] The present study was designed to determine whether different calcium concentrations in the vitrification solutions could improve the developmental competence of in vitro matured ovine oocytes after cryopreservation. ...
Comparación de la tasa de blastulación de embriones cultivados en grupo y en solitario en el modelo conejo

Tomás Rico, Ismael (Universitat Politècnica de València, 2022-09-08)

[EN] The development of artificial intelligence in embryology through the application of timelapse imaging technology is making a transition to individualized culture since it provides the ability to select the most ...
Correlated response in early embryonic development in rabbits selected for litter size variability

Calle, E. W.; García, M. L.; Blasco, A.; Argente, M.J. (Universitat Politècnica de València, 2017-12-28)

[EN] A divergent selection experiment for litter size variability was carried out in rabbits. The litter size variability was estimated as the phenotypic variance of litter size within female. The aim of this study was to ...
Differential mRNA Expression in Rabbit In vivo Pre-implantatory Embryos

Saenz de Juano Ribes, María de los Desamparados; Peñaranda, D.S.; Marco Jiménez, Francisco; Llobat, L; Vicente Antón, José Salvador (Wiley, 2011)

[EN] To study genes involved in embryo developmental competence and implantation in rabbits, the expression of a panel of genes related to pluripotency, angiogenesis, proliferation, apoptosis and differentiation were ...
Diseño y desarrollo de un sistema para predecir el potencial de implantación embrionaria en blastocistos desvitrificados.

Hidalgo Blasco, Ayelén (Universitat Politècnica de València, 2023-09-05)

[ES] La baja natalidad y el aumento de la esperanza de vida se presentan como un problema social y económico a largo plazo a nivel global. La baja natalidad está relacionada, en gran medida, con el incremento de la ...
Effects of slow freezing procedure on late blastocyst gene expression and survival rate in rabbit

Saenz de Juano Ribes, María de los Desamparados; Marco Jiménez, Francisco; Sánchez Peñaranda, David; Joly, Thierry; Vicente Antón, José Salvador (Society for the Study of Reproduction, 2012)

Studies of embryo cryopreservation efficiency have focused mainly on technical and embryo factors. To determine how a slow freezing process affects embryo and fetal development, we studied in vivo development ability after ...
First steps of in vitro gastrulation in rabbit vitrified embryos

Vicente Antón, José Salvador; Parrilla-Ocon, A.; Saenz de Juano Ribes, María de los Desamparados; Naturil Alfonso, Carmen; Marco Jiménez, Francisco (Cryo Letters, 2015-03)

[EN] The in vitro rabbit embryo production and their cryopreservation methodologies such as vitrification generate less viable embryos, and occasionally, with significant differences from those that are not subjected to ...
Parthenogenic blastocysts cultured under in vivo conditions exhibit proliferation and differentiation expression genes similar to those of normal embryos

Naturil Alfonso, Carmen; Saenz de Juano Ribes, María de los Desamparados; Peñaranda, D.S.; Vicente Antón, José Salvador; Marco Jiménez, Francisco (Elsevier Masson, 2011)

Parthenote embryos offer multiple possibilities in biotechnological investigation, such as stem cell research. However, there is still a dearth of knowledge of this kind of embryo. In this study, development and ploidy ...
Transcriptome profiling of rabbit parthenogenetic blastocysts developed under in vivo conditions

Naturil Alfonso, Carmen; Saenz de Juano Ribes, María de los Desamparados; Peñaranda, D.S.; Vicente Antón, José Salvador; Marco Jiménez, Francisco (Public Library of Science, 2012-12)

Parthenogenetic embryos are one attractive alternative as a source of embryonic stem cells, although many aspects related to the biology of parthenogenetic embryos and parthenogenetically derived cell lines still need to ...
