Single-cell microbeam irradiators are of increasing interest to the biological community. The 5th International Workshop on Microbeam Probes of Cellular Radiation Response, which took place in Stresa, Italy, in May 2001, was attended by about 120 registrants, roughly evenly divided between physicists and biologists. Many new microbeam devices are now under development, and there has been a sign...

The radiobiological features of leukemic progenitor cells (LPC) freshly obtained from 14 T-lineage acute lymphoblastic leukemia (ALL) and 11 B-lineage ALL patients were evaluated using LPC colony assays. No significant radiobiological differences were observed between T-lineage versus B-lineage ALL LPC. Notably, the l)a values displayed a significant interpatient variation in both groups, indic...

Introduction: Radiotherapy is one of the treatment options for locally advanced prostate cancer, however with standard radiation doses it is not always very effective. One of the strategies to improve the efficiency of radiotherapy is increasing the dose. In this study to increase tumor local control rates a new radiotherapy method, known as dose painting (DP) was investigated....
