background: boron neutron capture therapy (bnct) is a radiotherapy that combines biological targeting and high linear energy transfer. a potential therapeutic approach for non-small cell lung cancer (nsclc) is considered. however, dose in lung tumor is not homogeneous, and it will reduce the effect of bnct treatment. in order to improve the dose distribution of bnct, the multi-field irradiation...

There is an increasing interest in irradiation to control restenosis after balloon angioplasty by an internal radioactive source. Differences in radiosensitivity of the predominant cells of the human coronary artery (i.e. endothelial cells (HCAEC), smooth muscle cells from the media (HCMSMC) and from plaque material (HCPSMC), are issues of controversal discussion. Therefore, we investigated the...
