Intracytoplasmic Sperm Injection after Vitrification of Immature Oocytes in Follicular Fluid Increases Bovine Embryo Production
(Universidade Federal do Rio Grande do Sul, 2017)
Effects of gonadotrophins and insulin on glucose uptake in the porcine cumulus–oocyte complex during IVM
(Csiro Publishing, 2019-04)
The combination of gonadotrophins (LH and FSH) and insulin is frequently used in porcine oocyte IVM, but the individual effects of gonadotrophins and insulin have not been completely studied. The aim of this study was to ...
Behaviour of CRISP1 protein during capacitation and its role in gamete interaction
(Adthree Publishing, 2012)
Fertilization is a complex process that requires the successful completion of a series of orchestrated steps. In most invertebrates and non-mammalian vertebrates, spermatozoa that leave the testes already have the ability ...
Membrane-permeable Rab27A is a regulator of the acrosome reaction: Role of geranylgeranylation and guanine nucleotides
(Elsevier Science Inc, 2018-04)
The acrosome reaction is the regulated exocytosis of mammalian sperm's single secretory granule, essential for fertilization. It relies on small GTPases, the cAMP binding protein Epac, and the SNARE complex, among other ...
El rol de los glicoconjugados de las cubiertas ovocitarias en la fecundación del camarón de roca Rhynchocinetes typus (Milne-Edwards, 1837)Role of egg surface glycoconjugate in the fertilization of the rock shrimp Rhynchocinetes typus (Milne-Edwards, 1837)
(Pontificia Universidad Católica de Valparaíso, 2017)
Effect of insulin-transferrin-selenium and metformin on the in vitrofertilization of pigs
(IMR Press, 2021)
Brief introduction: The in vitro production of pig embryos is important for both commercial purposes and biomedical studies. It has a low efficiency mainly because in vitro maturation (IVM) systems are inefficient. ...
Epithelial and neural cadherin in mammalian fertilization: studies in the mouse model
(Multidisciplinary Digital Publishing Institute, 2022-01)
Successful mammalian fertilization requires a well-orchestrated sequence of molecular events leading to gamete fusion. Since this interaction involves Ca2+-dependent adhesion events, the participation of the Ca+2-dependent ...
Purification and biological characterization ofN-acetyl β-D glucosaminidase fromBufo arenarum spermatozoa
(Wiley-liss, Div John Wiley & Sons Inc, 2000)
Redistribution of the intra-acrosomal EGFP before acrosomal exocytosis in mouse spermatozoa
(Bioscientifica, 2015-05)
Mammalian spermatozoa must undergo complex physiological and morphological alterations within the female reproductive tract before they become fertilization competent. Two important alterations are capacitation and the ...
The antioxidant dimethylthiourea improves in vitro fertilization efficiency and decreases cumulus cells apoptosis in pigs
(Csiro Publishing, 2019-09)
Abattoir ovaries, which are the main source of oocytes for reproductive biotechnologies, arrive at the laboratory under ischaemic conditions. Reoxygenation generates reactive oxygen species (ROS) in ischaemic tissues, which ...
