        Particular features of gonadal maturation and size at first maturity in Atrina maura 

        Camacho-Mondragón, MA; Arellano Martínez, M; Ceballos Vázquez, BP (2012)
        The gonadal maturation of Atrina maura was examined by means of histological analysis and quantitative criteria. Particular features not previously described for this species are reported in this study: in both males and ...

        Sexual maturity in rabbits defined by the physical and chemical characteristics of the semen 

        Universidade Estadual Paulista (UNESP) (1978-12-01)

        Cytoplasmic maturation of bovine oocytes: Structural and biochemical modifications and acquisition of developmental competence 

        FERREIRA, E. M.; VIREQUE, A. A.; ADONA, P. R.; MEIRELLES, F. V.; FERRIANI, R. A.; NAVARRO, P. A. A. S. (ELSEVIER SCIENCE INC, 2009)
        Oocyte maturation is a long process during which oocytes acquire their intrinsic ability to support the subsequent stages of development in a stepwise manner, ultimately reaching activation of the embryonic genome. This ...

        Validation of macroscopic maturity stages of the Patagonian red octopus Enteroctopus megalocyathus 

        Ortiz, Nicolás (Cambridge University Press, 2013-02)
        Testes and ovaries of Enteroctopus megalocyathus collected along the Patagonian Atlantic coast were analysed histologically to validate the macroscopic maturity scales adopted for this species. Changes through the course ...

        Morphology and performance in water physical fitness test according to sexual and skeletal maturity in a group of Venezuelan swimmers. 

        Méndez de Pérez, Betty; Macías-Tomei, Coromoto; Landaeta-Jiménez, Maritza (2015)

        A Measure of Ecosystem Maturity. 

        Pérez España, Horacio; Arreguín Sánchez, Francisco (Ecological Modelling, 1999-01-01)
        A measure to quantify maturity in ecosystems is proposed. The index is based on the analysis of flows of biomass. A measure of the uncertainty of the determination of the route of a given particle of matter will follow ...

        Role of arachidonic acid cascade in Rhinella arenarum oocyte maturation 

        Ortiz, María Eugenia; Arias Torres, Ana Josefina; Zelarayán, Liliana Isabel (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 ...

        Allometric growth, sexual maturity and reproductive cycle ofAegla castro (Decapoda: Anomura: Aeglidae) from Itatinga, state of São Paulo, southeastern Brazil 

        Universidade de São Paulo (USP); Universidade Estadual Paulista (UNESP) (Sociedade Brasileira de Carcinologia, 2016)
        Abstract Allometric growth of chelae dimensions was analyzed to assess the average size at the onset of morphometric maturity (ASOMM) and sexual dimorphism regarding the pair of chelae in the Aegla castro. Both adult males ...

        Sexual development, size at maturity, size at maternity and fecundity of the blue shark Prionace glauca (Linnaeus, 1758) in the Southwest Atlantic 

        Fundacao Univ Fed Rio Grande; Universidade Estadual Paulista (UNESP) (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 ...

        Role of roscovitine and IBMX on kinetics of nuclear and cytoplasmic maturation of bovine oocytes in vitro 

        Universidade Estadual Paulista (UNESP) (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 ...
