Influence of caffeine pretreatment on biphasic in vitro maturation of dog oocytes.
Phosphodiesterase (PDE) inhibitors have been utilized for in vitro maturation (IVM) of oocytes to manipulate the meiotic resumption and progression. Premature chromatin condensation and DNA… Expand
Role of hyaluronic acid in maturation and further early embryo development of bovine oocytes.
Hyaluronic acid (HA), an important component of the extracellular matrix, plays a crucial role for cumulus cell expansion. Genes and proteins involved in HA synthesis and its receptor CD44 are… Expand
Effects of oxygen concentration on in vitro maturation of canine oocytes in a chemically defined serum-free medium.
Canine oocytes require an extended period of culture (72 h) in vitro for nuclear maturation to the metaphase II stage, which also results in high degeneration. Canine cumulus oocyte complexes were… Expand

Hyaluronan (HA) is a non-sulphated glycosaminoglycan polymer naturally occurring in many tissues and fluids of mammals, including the reproductive system. Its biosynthesis by HA synthase (HAS1-3) and… Expand
Studies on cryoprotectant toxicity to zebrafish (Danio rerio) ovarian tissue fragments.
Cryopreservation of ovarian tissue is a viable alternative to cryopreservation of oocytes and embryos in many species but it has not been studied in fish. Selection of cryoprotectant is an important… Expand
SMALL SIZE HYLURONAN PROMOTES BOVINE OOCYTE MATURATION AND EMBRYO DEVELOPMENT IN VITRO
EMBRYOLOGY: O-11: PRENATAL OOGENESIS: SELECTING THE QUALITY AND QUANTITY OF OOCYTES IN THE OVARIAN RESERVE
Effect of different concentrations and molecular weight of hyaluronic acid on survival of in vitro sheep embryos after cryopreservation.
Exact shock profile for the ASEP with sublattice-parallel update
We analytically study the one-dimensional asymmetric simple exclusion process with open boundaries under sublattice-parallel updating scheme. We investigate the stationary state properties of this… Expand
