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)
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 proposed that a group of genes whose expression is enhanced by polyamines at the level of translation in Escherichia coli and mammalian cells be referred to as a "polyamine modulon". In Saccharomyces cerevisiae, proteins whose synthesis is enhanced by polyamines at the level of translation were searched for using a polyamine-requiring mutant of S.(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)
