(SOC BIOLGIA CHILE, 2011)We evaluated the effect of time and temperature on acrosin release from the acrosomal cap and the activity of this enzyme during in vitro capacitation in fresh and frozen/thawed dog sperm. Sperm-rich fractions of six ...
-
(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 ...
-
(ELSEVIER SCIENCE INC, 2005-07-01)he IVM of canine oocytes is characterized by low rates of metaphase H. The objective of this study was to evaluate the effects of hCG on mciotic development of canine oocytes for culture periods up to 96 h. Oocytes were ...
-
Evaluation of cortical granules and viability of canine oocytes during long-term in vitro maturation (BRITISH VETERINARY ASSOC, 2007-02-10)
-
(Universidad de Chile, 2018)La flotabilidad de los embriones tempranos de peces pelágicos se asocia a la calidad y sobrevivencia de éstos. En cautiverio se ha observado una alta mortalidad embrionaria que se ha relacionado con la pérdida de ...
-
(Universidad de Chile, 2013)El pez dorado S. lalandi, es una especie marina pelágica, que posee características favorables para su producción intensiva, tales como altas tasas de crecimiento y de conversión alimenticia, resistencia a las altas ...
-
(Universidad de Chile, 2016)En especies pelágicas como S. lalandi, se ha descrito que la flotabilidad en huevos y embriones es el reflejo de la viabilidad y calidad de estos. Esta característica, se adquiere con la proteólisis del vitelo provocando ...
-
(Universidad de Chile, 2018)La mortalidad embrionaria que se ha observado en condiciones de cultivo del pez dorado Seriola lalandi, puede ser mencionada entre los principales obstáculos que han frenado el desarrollo acuícola de esta especie en nuestro ...
-
Expression of growth differentiation factor 9 (GDF-9) during in vitro maturation in canine oocytes (Elsevier, 2013)The aim of this study was to characterize in canine oocytes and cumulus cells the dynamic expression of growth differentiation factor 9 (GDF-9) in relation to meiotic development and cumulus expansion throughout in vitro ...
-
(2012)Content: The Golgi apparatus (GA) and endoplasmic reticulum (ER) play a central role in the events related to intracellular trafficking distribution. This work evaluated the dynamics and localization of the GA and ER in ...
-
(ELSEVIER SCIENCE BV, 2009-01)The aim of this study was to evaluate the effect of sperm cryopreservation and the maturation state of the oocyte on the time course of canine gamete interaction during co-culture for periods of 1–10 h. Semen samples were ...
-
(Elsevier, 2011)The objective was to evaluate mitochondrial distribution, and its relationship to meiotic development, in canine oocytes during in vitro maturation (IVM) at 48, 72, and 96 h, compared to those that were non-matured or in ...
-
(2012-12)Contents The objectives of this study were to evaluate the sperm nuclear decondensation capacity of ovulated and in vitro-matured (IVM) canine oocytes during different culture times and correlate this decondensation ability ...
