Journal ArticleDOI
Development of a new water sterilization device with a 365 nm UV-LED
Mirei Mori,Akiko Hamamoto,Akira Takahashi,Masayuki Nakano,Noriko Wakikawa,Satoko Tachibana,Toshitaka Ikehara,Yutaka Nakaya,Masatake Akutagawa,Yohsuke Kinouchi +9 more
TL;DR: Taking advantage of the safety and compact size of LED devices, it is expected that the UVA-LED sterilization device can be developed as a new type of water sterilization devices.
Journal ArticleDOI
New water disinfection system using UVA light-emitting diodes
Akiko Hamamoto,Mirei Mori,Akira Takahashi,Masayuki Nakano,Noriko Wakikawa,Masatake Akutagawa,Toshitaka Ikehara,Yutaka Nakaya,Yohsuke Kinouchi +8 more
TL;DR: To evaluate the ability of high‐energy ultraviolet A (UVA) light‐emitting diode (LED) to inactivate bacteria in water and investigate the inactivating mechanism of UVA irradiation.
Journal ArticleDOI
Vibrio parahaemolyticus infection induces modulation of IL-8 secretion through dual pathway via VP1680 in Caco-2 cells.
Takaaki Shimohata,Masayuki Nakano,Xin Lian,Tomomi Shigeyama,Hitomi Iba,Akiko Hamamoto,Masaki Yoshida,Nagakatsu Harada,Hironori Yamamoto,Masayuki Yamato,Kazuaki Mawatari,Toshiaki Tamaki,Yutaka Nakaya,Akira Takahashi +13 more
TL;DR: It is shown that V. parahaemolyticus infection of Caco-2 cells results in the secretion of IL-8, and that VP1680 plays a pivotal role in manipulating host cell signaling and is responsible for triggering IL- 8 secretion.
Journal ArticleDOI
Insulin activates ATP-sensitive potassium channels via phosphatidylinositol 3-kinase in cultured vascular smooth muscle cells.
Sonoko Yasui,Kazuaki Mawatari,Takashi Kawano,Ran Morizumi,Akiko Hamamoto,Hiroko Furukawa,Kei Koyama,Aki Nakamura,Atsushi Hattori,Masayuki Nakano,Nagakatsu Harada,Toshio Hosaka,Akira Takahashi,Shuzo Oshita,Yutaka Nakaya +14 more
TL;DR: Using the potential-sensitive fluorescence dye bis-(1,3-dibutylbarbituric acid)trimethine oxonol [DiBAC4(3)], it is found that insulin induced membrane hyperpolarization after 2 min in A10 cells, and data suggest that KATP channel activation by insulin is mediated by PI3-K.
Proceedings ArticleDOI
Sterilization Using 365 nm UV-LED
N. Yagi,Mirei Mori,Akiko Hamamoto,Masayuki Nakano,Masatake Akutagawa,Satoko Tachibana,Akira Takahashi,Toshitaka Ikehara,Yohsuke Kinouchi +8 more
TL;DR: The results have showed that complete germicidal effects for E. coli and Vibrio parahaemolyticus are caused by UV-LED exposure of 30 minutes and 10 minutes, respectively, suggesting that the UV- LED has sterilization effects.
