Histochemical and morphological features of biopsied and stripped oocytes from the Brazilian endangered teleost pirapitinga, Brycon nattereri (Characiformes)
(Cambridge Univ Press, 2015-06-01)
The aim of the present study was to characterize biopsied and stripped oocytes from the Brazilian endangered teleost pirapitinga (Brycon nattereri) using histochemical and morphological analyses. Biopsied oocytes had a ...
Global poly(A) mRNA expression profile measured in individual bovine oocytes and cleavage embryos
(CAMBRIDGE UNIV PRESS, 2008)
The objective of this article was to estimate quantitative differences for GAPDH transcripts and poly(A) mRNA: (i) between oocytes collected from cumulus-oocyte complexes (COCs) qualified morphologically as grades A and ...

Role of arachidonic acid cascade in Rhinella arenarum oocyte maturation
(Cambridge University Press, 2015-08)
There are no studies that document the production of prostaglandins (PGs) or their role in Rhinella arenarum oocyte maturation. In this study, we analysed the effect of arachidonic acid (AA) andprostaglandins (PGs) on ...
Decreased fertility in poor responder women is not related to oocyte morphological status
(Termedia Publishing House Ltd, 2011-04-01)
Introduction: In women showing impaired fertility, a decreased response to ovarian stimulation is a major problem, limiting the number of oocytes to be used for assisted reproduction techniques (ART). Despite the several ...
Chilling sensitivity of Steindachneridion parahybae (Siluriformes: Pimelodidae) oocytes in different cryoprotectants
(2019-06-01)
The viability of post-thaw fish oocytes can be affected by different stages of the freezing process, such as cryoprotectant toxicity, cold sensitivity, freezing curves and thawing. Therefore, these steps need to be ...
Roscovitine use for the delay of meiotic progression in prepubertal sheep oocytes
(Empresa Brasil Pesq Agropec, 2020-01-01)
The objective of this work was to evaluate the efficiency of roscovitine on reversibly inhibiting oocytes from prepubertal sheep at the germinal vesicle (GV) stage, and to investigate the kinetics of meiosis progression ...
