N-methyl-D-aspartate receptors (NMDAR) overactivation is linked to neurodegeneration. The current prevailing theory suggests that synaptic and extrasynaptic NMDAR (syn- and ex-NMDAR) impose counteracting effects on cell fate, and neuronal cell death is mainly mediated by the activation of ex-NMDAR. However, several lines of evidence implicate the limitation(More)
Leaf gas exchange and chlorophyll fluorescence of Glycyrrhiza uralensis Fisch at two water supplies (equivalent to 240 mm for present precipitation and to 120 mm for future decreasing precipitation) were compared. There was a midday depression in net photosynthetic rate (P N) for either treatment, but stomatal limitation was dominant for present(More)
Hexagonal cavities and their applications to multilayer substrate integrated waveguide (SIW) filters are presented. The hexagonal SIW cavity which can combine flexibility of rectangular one and performance of circular one is convenient for bandpass filter's design. Three types of experimental configuration with the same central frequency of 10 GHz and(More)
Mechanisms underlying tolerance to and dependence on the anticonvulsant effect of clonazepam are not clear. Autoradiography of the NMDA receptors in amygdala-kindled rats with tolerance to and dependence on the anticonvulsant effect of clonazepam was carried out. When tolerance developed, the binding of [3H] TCP (N-(1-thieny) cyclohexylpiperidine) to NMDA(More)
