Vitrification by Cryotop and the Maturation, Fertilization, and Developmental Rates of Mouse Oocytes
Vitrification Fertilization Maturation Cryotop Developmental Rate Oocyte
2015/11/9
Background: Oocyte cryopreservation is an important part of modern fertility treatment. The effect of vitrification on the fertilization and developmental rates of embryo is still a matter of debate.
Effects of inhibiting nitric oxide synthase on cumulus expansion and nuclear maturation of sheep oocytes
sheep oocyte maturation nitric oxide L-NAME
2015/6/9
Nitric oxide (NO) is a biological signaling molecule that plays a crucial role in oocyte maturation of mammalians. It is generated by the nitric oxide synthase (NOS) enzyme from l-arginine. Although t...
Effects of genistein and genistin on in vitro maturation of pig oocytes
phytoestrogen isoflavone oocyte maturation pig estrogenic effect tyrosine protein kinase
2015/6/5
The objective of the study was to verify the hypothesis that GEN (genistein – phytoestrogen and an inhibitor of tyrosine protein kinase – TPK) effects on pig oocyte maturation and cumular cell expansi...
The influence of cadmium on Prussian carp oocyte maturation, development of eggs and hatching
heavy metals oocyte maturation steroid hormones embryonic development hatching enzyme
2015/6/5
The influence of cadmium (Cd) on the last stage of Prussian carp (Carassius auratus gibelio B.) oocyte maturation and embryonic development was investigated. The (postvitellogenic) oocytes were incuba...
Selected molecular and microfluidic aspects of mammalian oocyte maturation-perspectives: a review
microfluidics Lab-on-chip oocyte maturation media supplementation
2015/4/15
Maturation of oocytes is the most important stage, which determines the subsequent successful fertilization, zygote formation, attainment of blastocyst stage, normal embryo growth and development, as ...
Induction of final oocyte maturation in Cyprinidae fish by hypothalamic factors: a review
reproductive dysfunction ovulation luteinizing hormone
2015/4/2
Gonadotropin-releasing hormone in Cyprinidae as in other Vertebrates functions as a brain signal which stimulates the secretion of luteinizing hormone from the pituitary gland. Two forms of gonadotrop...
In vitro maturation and degeneration of domestic cat oocytes collected from ovaries stored at various temperatures
IVM feline COC apoptosis necrosis
2015/4/1
Cat oocytes have the unique ability to mature in vitro after temporary storage at 4°C which can provide opportunities to rescue oocytes from the ovaries of endangered felids after sudden death or medi...
Oestrous cycle stage influences the morphology and maturation of porcine oocytes in vitro
gilts follicular development oocytes morphology meiotic competence
2015/3/17
The objective of the study was to characterize the effect of the oestrous cycle stage on the yield,
morphology and meiotic competence of porcine oocytes. A total of 46 cycling gilts, at 8.5–9 months...
Effect of Dipeptides on In vitro Maturation, Fertilization and Subsequent Embryonic Development of Porcine Oocytes
Ammonia Accumulation Dipeptides Incorporation and Oxidation Porcine Embryos
2016/5/11
The effects of amino acids and dipeptides on in vitro production of porcine embryos and accumulation of ammonia in culture medium during developmental stages were examined in this study. The maturatio...
