The transmembrane and pore-forming regions of N-methyl-D-aspartate receptors containing the NR1 and NR2B subunits were studied by measuring the effects of various NR1 and NR2B mutants on stimulation and block by spermine. Block by spermine was predominantly affected by mutations in the M3 segment of NR1 and especially in the M1 and M3 segments of NR2B.(More)
80 Gbit/s operation of a static D-type flip-flop (D-FF) circuit was achieved using InP-based HEMT technology with a cut-off frequency of 245 GHz and a transconductance of 1500 mS/mm. To generate 80 GHz differential clock signals from the single phase one in the circuit, a rat-race circuit was placed in front of the clock buffer. The power supply voltage was(More)
Anthraquinone spermine [N1-(anthraquinone-2-carbonyl)spermine; AQ343], anthraquinone homospermine [N1-(anthraquinone-2-carbonyl; AQ444], anthracene spermine [N1-(9-anthracenylmethyl)spermine; Ant343], and anthracene homospermine [N1-(9-anthracenylmethyl)homospermine; Ant444] were found to be potent antagonists of recombinant N-methyl-D-aspartate (NMDA)(More)
We reported a case of basilar artery dissection in a 20-year-old man suffering sudden onset of consciousness disturbance. Brain CT revealed a cerebral infarction of the whole territories of vertebro-basilar artery and his 3DCT showed the occlusion at the base of basilar artery. Autopsy revealed that the subintimal dissection was found at the base of basilar(More)
