Role of roscovitine and IBMX on kinetics of nuclear and cytoplasmic maturation of bovine oocytes in vitro
(Elsevier B.V., 2007-05-01)
The 3-isobutyl-1-methylxanthine (IBMX) is able to prevent resumption of meiosis by maintaining elevated cyclic AMP (cAMP) concentrations in the oocyte, and roscovitine, a purine known to specifically inhibit MPF kinase ...

Distribution of cortical granules and meiotic maturation of canine oocytes in bi-phasic systems
(2015-01-01)
The aim of this study was to evaluate the influence of different bi-phasic systems with gonadotrophins and steroids on in vitro maturation rates of oocytes obtained from bitches at different reproductive stages (follicular, ...
Sexual development, size at maturity, size at maternity and fecundity of the blue shark Prionace glauca (Linnaeus, 1758) in the Southwest Atlantic
(Elsevier B.V., 2014-12-01)
Size at maternity and size at maturity of the blue shark Prionace glauca were studied from samples collected during ten commercial longline fishing cruises off southern Brazil and in adjacent international waters. The sharp ...
Effect of Hormonal Supplementation Periods and In Vitro Maturation Media on Developmental Competence of Pig Oocytes
(UNIV FED RIO GRANDE DO SUL, 2010)
Background: The oocyte ability to undergo successful fertilization, cleavage and embryonic development depends on meiotic maturation and developmental competence acquisition. In vitro maturation (IVM) protocols currently ...
Involvement of PLA2, COX and LOX in Rhinella arenarum oocyte maturation
(Cambridge University Press, 2013-02)
In Rhinella arenarum, progesterone is the physiological nuclear maturation inducer that interacts with oocyte surface and starts a cascade of events leading to germinal vesicle breakdown (GVBD). Polyunsaturated fatty acids ...
An inverse relationship between stability and maturity in models of aquatic ecosystems
(Ecological Modelling, 2001)
The relationships among stability, maturity and complexity of ecosystems have been studied for many years. These ecosystem attributes are important in ecological theory and also for the appropriate management of resources. ...
Relating maturity levels in environmental management by adopting Green Supply Chain Management practices: Theoretical convergence and multiple case study
(2019-01-01)
Although the thematic maturity levels of corporate environmental management and the adoption of Green Supply Chain Management (GSCM) practices are consolidating, they have passed through long ways disconnected, given that ...
Maturity grid to evaluate and improve environmental management in industrial companies
(2020-09-01)
Abstract: The increase in industrial activities to meet the growing needs of the population has led many companies to adopt environmental management (EM) policies to offset their impacts on the environment. For this reason, ...
