Results of heavy ion radiotherapy [PDF]

open access: yesRadiation and Environmental Biophysics, 1995
The potential of heavy ion therapy for clinical use in cancer therapy stems from the biological parameters of heavy charged particles and their precise dose localization. Biologically, carbon, neon, and other heavy ion beams (up to about silicon) are clinically useful in overcoming the radioresistance of hypoxic tumors, thus increasing the biological ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Carbon ion FLASH irradiation reduces acute skin toxicity compared with conventional dose rate irradiation

open access: yesScientific Reports
FLASH radiotherapy, defined by ultra-high dose rates exceeding 40 Gy/s, has shown potential for widening the therapeutic window due to its demonstrated normal tissue-sparing effects while maintaining tumor control with electrons, photons, and protons ...

The influence of C-ions and X-rays on human umbilical vein endothelial cells

open access: yesFrontiers in Oncology, 2016
Damage to the endothelium of blood vessels, which may occur during radiotherapy, is discussed as a potential precursor to the development of cardiovascular disease. We thus chose human umbilical vein endothelial cells (HUVEC) as a model system to examine
