Journal ArticleDOI
Exosome-mediated radiosensitizing effect on neighboring cancer cells via increase in intracellular levels of reactive oxygen species.
Ai Nakaoka,Makiko Nakahana,Sachiko Inubushi,Hiroaki Akasaka,Mohammed Salah,Yoshiko Fujita,Hikaru Kubota,Mennaallah Hassan,Ryo Nishikawa,Naritoshi Mukumoto,Takeaki Ishihara,Daisuke Miyawaki,Takashi Sasayama,Ryohei Sasaki +13 more
TL;DR: The role of exosomes in intercellular communication between cancer cells following radiation exposure is unclear as mentioned in this paper, however, the exact mechanism of the interaction between cells and neighboring cancer cells is unclear.
Journal ArticleDOI
Investigation of the potential of using TiO2 nanoparticles as a contrast agent in computed tomography and magnetic resonance imaging
Hiroaki Akasaka,Naritoshi Mukumoto,Masao Nakayama,Tianyuan Wang,Ryuichi Yada,Yasuyuki Shimizu,Sachiko Inubushi,Katsusuke Kyotani,Keisuke Okumura,Masanori Miyamoto,Ai Nakaoka,Kenta Morita,Yuya Nishimura,Chiaki Ogino,Ryohei Sasaki +14 more
TL;DR: The results suggest that TiO2 can potentially be used as a novel theranostic drug with radiosensitizing ability and radiological diagnostic ability, through modification of chemical groups on its surface, and as a component of drug delivery systems.
Journal ArticleDOI
A Comparative Assessment of Mechanisms and Effectiveness of Radiosensitization by Titanium Peroxide and Gold Nanoparticles.
Mennaallah Hassan,Masao Nakayama,Masao Nakayama,Mohammed Salah,Mohammed Salah,Hiroaki Akasaka,Hikaru Kubota,Makiko Nakahana,Tatsuichiro Tagawa,Kenta Morita,Ai Nakaoka,Takeaki Ishihara,Daisuke Miyawaki,Kenji Yoshida,Yuya Nishimura,Chiaki Ogino,Ryohei Sasaki +16 more
TL;DR: A comparison of the types and amounts of ROS generated showed that hydrogen peroxide generation by PAA-TiOxNPs was the major factor that contributed to the nanoparticle radiosensitization.
Journal ArticleDOI
A treatment planning study comparison between supine and prone position for different lung tumour locations using CyberKnife TPS
Hiroaki Akasaka,Kazufusa Mizonobe,Yuya Oki,Kazuyuki Uehara,Aya Harada,Shuichiro Miyazaki,Keiji Kitatani,Tomonori Yabuuchi,Takeaki Ishihara,Daisuke Miyawaki,Masao Nakayama,Naritoshi Mukumoto,Ryuichi Yada,Ai Nakaoka,Hikaru Kubota,Hiroki Kawaguchi,Satoshi Seno,Ryohei Sasaki,Hiroshi Mayahara +18 more
TL;DR: The results may be deployed in CyberKnife treatment planning to monitor normal tissue dose by considering patient positioning to assist in the design of better treatment plans and prevention of symptomatic radiation pneumonitis in lung cancer patients.
Journal ArticleDOI
The air gap between bolus and skin affects dose distribution in helical and direct tomotherapy
Hiroaki Akasaka,Yuya Oki,Kazufusa Mizonobe,Kazuyuki Uehara,Hiroshi Mayahara,Aya Harada,Naoki Hashimoto,Keiji Kitatani,Tomonori Yabuuchi,Takeaki Ishihara,Kazuma Iwashita,Daisuke Miyawaki,Naritoshi Mukumoto,Ai Nakaoka,Ryohei Sasaki +14 more
TL;DR: HT technique is a good choice, but DT technique can be also used if the bolus position can be reproduced accurately, and the reproducibility of the bolu position between planning and treatment is very important.
