Times Cited Count：7 Percentile：52.3(Radiology, Nuclear Medicine & Medical Imaging)The dosimeter system is capable of real-time, accurate, and precise measurement under stereotactic body radiation therapy (SBRT) conditions. The probe is smaller than a conventional dosimeter, has excellent spatial resolution, and can be valuable in SBRT with a steep dose distribution over a small field. The developed PSP dosimeter system appears to be suitable for in vivo SBRT dosimetry.

Times Cited Count：21 Percentile：80.21(Biology)In an effort to assess the characteristics of mutation induced by different LET radiation in higher plants, the mutational effects of carbon-ion beams and 
-rays were investigated in . The transgenic (Arabidopsis/rpsL) mutation detection system was adopted. Dry seeds of Arabidopsis/rpsL were irradiated with -rays and 208-MeV carbon ions (208-MeV 
C
), and the mutation frequency and mutation spectrum were examined. Our result suggested that 208-MeV C and -rays induced different mutational effects in dry seed.

We generated a CPD photolyase knock-down in 
by RNAi to investigate the role of CPD photorepair for protection of plants from solar UV. These knock-down lines exhibited hypersensitivity to UV-B and an increased occurrence of mutation induced by UV-B radiation compared with proficient in CPD photolyase. These results indicate that CPD photoreactivation plays an important role for UV resistance of and suppression of UV-induced mutagenesis.
