Journal ArticleDOI
A cephalometric and electromyographic study of upper airway structures in the upright and supine positions
TL;DR: It is proposed that body posture has a substantial effect on upper airway structure and muscle activity and should be taken into account when assessingupper airway size in the erect posture and in the supine position (computed tomography).
Journal ArticleDOI
Photolysis of Hydrogen Peroxide, an Effective Disinfection System via Hydroxyl Radical Formation
Hiroyo Ikai,Keisuke Nakamura,Midori Shirato,Taro Kanno,Atsuo Iwasawa,Atsuo Iwasawa,Keiichi Sasaki,Yoshimi Niwano,Masahiro Kohno +8 more
TL;DR: Electron spin resonance spin trapping analysis showed that the amount of hydroxyl radicals produced increased with the irradiation time, and demonstrated that the bactericidal activity of S. mutans in a model biofilm was dependent on the number of hydoxyl radicals generated.
Journal ArticleDOI
Inhibition of specific binding of okadaic acid to protein phosphatase 2A by microcystin-LR, calyculin-A and tautomycin: method of analysis of interactions of tight-binding ligands with target protein
Akira Takai,Keiichi Sasaki,H Nagai,Gottfried Mieskes,Minoru Isobe,Kiyoshi Isono,Takeshi Yasumoto +6 more
TL;DR: The results indicate that the binding of the unlabelled inhibitors to the PP2A molecule causes a dramatic (10(6)-10(8)-fold) increase in the dissociation constant associated with the interaction of [24-3H]OA and PP1, which suggests that OA and the other inhibitors bind to PP1 in a mutually exclusive manner.
Journal ArticleDOI
Relationships Between the Size, Position, and Angulation of Human Jaw Muscles and Unilateral First Molar Bite Force
TL;DR: Jaw muscle size alone seems to explain most of the variation in bite force reported by ourselves and others, despite the fact that craniofacial spatial morphology may differ among subjects.
Journal ArticleDOI
Reevaluation of analytical methods for photogenerated singlet oxygen
Keisuke Nakamura,Kirika Ishiyama,Hiroyo Ikai,Taro Kanno,Keiichi Sasaki,Yoshimi Niwano,Masahiro Kohno +6 more
TL;DR: In photodynamic therapy, it is suggested that the relative yield of singlet oxygen generated by various photosensitizers can be evaluated properly by electron spin resonance analysis.
