Meiotic arrest of sheep oocytes using roscovitine under different medium compositions
(Elsevier B.V., 2015-05-01)
Attempts to maintain the meiotic arrest under suitable culture conditions have been performed in order to improve the quality of oocytes in vitro matured. So, our study aimed to evaluate the potential of roscovitine, an ...
Time course of the meiotic arrest in sheep cumulus-oocyte complexes treated with roscovitine
(Cambridge University Press, 2015)
Temporary meiosis arrest with cyclin-dependent kinases inhibitors has been proposed in order to improve the quality of in vitro matured oocytes. In sheep, however, this phenomenon has been rarely investigated. Therefore, ...
Enhanced fertility and chill tolerance after cold-induced reproductive arrest in females of temperate species of the Drosophila buzzatii complex
(Company of Biologists, 2017-02)
Long-term exposure to low temperatures during adult maturation might decrease fertility after cold recovery as a consequence of carryover effects on reproductive tissues. This pattern should be more pronounced in tropical ...
Simultaneous expression analysis of deleted in azoospermia-family genes and CDC25A: their potential as a predictor for successful testicular sperm extraction
(Nature Publishing Group, 2017-11)
The Deleted in Azoospermia (DAZ) gene family consists of two autosomal genes, BOULE and DAZ-L (DAZ-like), and the DAZ gene cluster on chromosome Y. These genetic factors encode for RNA-binding proteins that are mainly ...
Meiotic inhibition of bovine oocytes in medium supplemented with a serum replacer and hormones: effects on meiosis progression and developmental capacity
(Cambridge University Press, 2011-05-01)
Aiming to improve the developmental competence of bovine oocytes during meiotic block, this study evaluated the effects of a serum replacer (Knockout SR(R)) and hormones (gonadotropins and estradiol) supplementation of ...

Prematuration of bovine oocytes with butyrolactone I reversibly arrests meiosis without increasing meiotic abnormalities after in vitro maturation
(ELSEVIER IRELAND LTD, 2009)
Objectives: Asynchrony between nuclear and cytoplasmic maturation, and possibly damage to the oocyte meiotic spindle, limits the application of in vitro maturation (IVM) in assisted reproduction. Several studies have ...
