In mammalian and amphibian oocytes, the meiotic arrest at the G2/M transition is dependent on cAMP regulation. Because genetic inactivation of a phosphodiesterase expressed in oocytes prevents reentry into the cell cycle, suggesting autonomous cAMP synthesis, we investigated the presence and properties of the G-protein-coupled receptors (GPCRs) in rodent(More)
In most species, the meiotic cell cycle is arrested at the transition between prophase and metaphase through unclear somatic signals. Activation of the Cdc2-kinase component of maturation promoting factor (MPF) triggers germinal vesicle breakdown after the luteinizing hormone (LH) surge and reentry into the meiotic cell cycle. Although high levels of cAMP(More)
Mammalian oocytes are arrested in prophase of the first meiotic division. Progression into the first meiotic division is driven by an increase in the activity of maturation-promoting factor (MPF). In mouse oocytes, we find that early mitotic inhibitor 1 (Emi1), an inhibitor of the anaphase-promoting complex (APC) that is responsible for cyclin B destruction(More)
HOMO level of the PBDTTT-based polymer was successfully reduced by introducing an ketone group in place of the ester group. The average PCE of the PBDTTT-based devices reached 6.3% with a champion PCE result of 6.58%. Due to its highly efficient photovoltaic performance and more feasible synthesis approach, PBDTTT-C has the potential to be successfully(More)
Mobility support for Internet devices is quite important for consumer electronics and the number of the handled device is growing up quickly. However, the IP addresses are not enough for the number of the rapidly grow devices in the All-IP generation. So the IPv6 is adopted to solve these problems. Our purposed structure is based on the IEEE 802.11. However(More)
