The Gompertz model is the long-time well-known mathematical model of exponential expression among mortality models in the literature that are used to describe mortality and survival data of a population. The death rate of the “probacent” model developed by the author based on animal experiments, clinical applications and mathematical reasoning was applied to predict age-specific death rates in ...
The aim of this study was to compare the dosimetric characteristics of left-sided whole breast irradiation among 3-dimensional conformal radiotherapy (3D-CRT), 4-field inverse-planned intensity-modulated radiotherapy (IP-IMRT) and hybrid IMRT technique (combining 3D-CRT beams and IP-IMRT beams) with respect to target coverage and irradiation of organs at risk. The 3 different planning technique...
High frequency (90 %) induction of thymic lymphomas by whole-body X irradiation with 4 repeats of 1.8 Gy (total dose: 7.2 Gy) in C57BL/6 mice was suppressed to 43 % by continuous whole-body irradiation of mice with Cs g rays at a low dose rate of 1.2 mGy/h for 450 days, starting 35 days before the challenging irradiation. The continuous 1.2 mGy/h irradiation, administering a total dose of 7.2 G...
