Photon and Proton irradiation in Patient-derived, Three-Dimensional Soft Tissue Sarcoma Models [PDF]

open access: yesBMC Cancer, 2023
Background Despite their heterogeneity, the current standard preoperative radiotherapy regimen for localized high-grade soft tissue sarcoma (STS) follows a one fits all approach for all STS subtypes. Sarcoma patient-derived three-dimensional cell culture

Impact of hypoxic versus oxic conditions on local tumor control after proton irradiation in a rat prostate carcinoma [PDF]

open access: yesClinical and Translational Radiation Oncology
Background and purpose: Hypoxia in tumors significantly contributes to radiation resistance, often leading to poor treatment outcomes. In vitro studies demonstrated that proton irradiation not only exhibits an increased relative biological effectiveness (

Proton and Au-ion irradiation induced damage and hardening in ferritic/martensitic steel

open access: yesNuclear Materials and Energy, 2021
Ferritic/martensitic (F/M) steel was irradiated by proton and Au-ion at 400 °C to investigate the irradiation damage and hardening behavior. For the samples irradiated by proton, dislocation loops and dislocation lines were found in F/M steels and the ...
