Unlike in other domestic animals, in vitro maturation (IVM) of canine oocytes has had limited success. The present study investigated the effect of the estrous cycle and estradiol-17beta (E2) or progesterone (P4) supplementation on in vitro nuclear maturation of canine oocytes recovered from domestic dog ovaries in various reproductive states (follicular,(More)
Supplementation of beta-mercaptoethanol (beta-ME) in in vitro maturation (IVM) medium was shown to improve embryo development and quality in several species. Epidermal growth factor (EGF) was also shown to improve IVM of human oocyte and embryo development after in vitro fertilization (IVF). The effect of these two compounds were suggested to be mediated(More)
Using slice patch clamp recording, we examined the effects of general anesthetic propofol (2,6-diisoprophlphenol) on dual modality of GABA(A) inhibition in supraoptic nucleus (SON) magnocellular neurosecretory cells (MNCs): conventional quantal synaptic transmission (IPSCs, I(phasic)) and persistent tonic form of inhibitory current (I(tonic)). Propofol (10(More)
Activation of serotonin (5-hydroxytryptamine, 5-HT) receptors produces various autonomic and neuroendocrine responses in the hypothalamic paraventricular nucleus (PVN), including increased blood pressure and heart rate. However, the role(s) of 5-HT on the local GABA synaptic circuit have not been well understood in the PVN, where the inhibitory(More)
