Abstract Many reports have demonstrated that radiation stimulates reactive oxygen species (ROS) production by mitochondria for a few hours to a few days after irradiation. However, these studies were performed using cell lines, and there is a lack of

OBJECTIVE An autologous formalin-fixed tumor vaccine (AFTV) derived from resected glioblastoma (GBM) tissue can be used against unidentified tumor antigens. Thus, the authors conducted a multicenter double-blind phase IIb trial to investigate the eff

Purpose Danger signals and release of tumor-specific antigens after exposure to ionizing radiation can convert an irradiated tumor into an in situ vaccine. However, radiation alone is not sufficient to induce an effective systemic immune response. In

Fractionated proton beam radiotherapy is spreading worldwide these days. However, biological data of sub-lethal damage recovery (SLDR) after proton irradiation is not known yet. We here conducted split-dose experiments (20-360 min intervals) to clari

Protons were discovered by Rutherford E in 1919. Following the invention and development of cyclotron invented by Lawrence EO in 1931, Wilson RR proposed the medical use of accelerated high energy protons in 1946. To realize his proposal, Lawrence JH
