Skin flash radiotherapy
Webbför 2 dagar sedan · A bug that caused the quadrocopter of the air defence soldier to capture points in the “Mobile Infantry” event has been fixed. The current provided changelog reflects the major changes within the game as part of this Update. Some updates, additions and fixes may not be listed in the provided notes. WebbUltrahigh–dose rate FLASH radiotherapy (FLASH-RT) is a potentially paradigm-shifting treatment modality that holds the promise of expanding the therapeutic index for nearly any cancer. At the heart of this exciting technology comes the capability to ameliorate major normal tissue complications without compromising the efficacy of tumor killing.
