Preliminary analysis of a radiobiological experiment for LifeSat [PDF]

With the possibility of performing radiation life science experiments on a dedicated satellite (LifeSat) in space, a combined effort in radiation physics and radiation dosimetry, in addition to radiation biology, is clearly required to ensure that ...

Advancing proton therapy: Dosimetric superiority of proton arc therapy over IMPT in esophageal cancer treatment

Journal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Background and aims Esophageal cancer presents significant treatment challenges due to its proximity to critical structures such as the heart, lungs, and spinal cord. While intensity‐modulated proton therapy (IMPT) improves dose conformity, it is limited by factors such as the number of beam angles and lateral penumbra. Proton arc therapy (PAT)

Immune Checkpoint Inhibitors and Immunomodulators for Cancer Immunotherapy: Insights Into Resistance and Therapeutic Strategies

Advanced Science, Volume 13, Issue 25, 4 May 2026.
The schematic diagram illustrates the roles of novel immune checkpoints, immunomodulatory factors, cell death and multimodal technologies in cancer immunotherapy. Abstract Cancer immunotherapy has redefined cancer treatment. However, the molecular and cellular basis of immune evasion and therapeutic resistance remains incompletely understood.

Comparison of X-ray and gamma-ray dose-response curves for pink somatic mutations in Tradescantia clone 02 [PDF]

, 1976
Microdosimetric data indicate that the mean specific energy,zeta, produced by individual charged particles from X rays and gamma rays is different for the two radiation qualities by nearly a factor of two.

Hypofractionated Spot Scanning Proton Therapy for Head and Neck Mucosal Melanoma: A Retrospective Analysis With Quality‐of‐Life Outcome

Head &Neck, Volume 48, Issue 5, Page 1208-1217, May 2026.
ABSTRACT Objective To evaluate clinical outcomes and quality of life (QOL) following hypofractionated spot‐scanning proton therapy (SSPT) for head and neck malignant mucosal melanoma (HNMM). Methods This retrospective study included 39 patients treated with SSPT (60–64 Gy[RBE] in 15–16 fractions) between 2013 and 2023.

Evaluation of specific RBE in different cells of hippocampus under high-dose proton irradiation in rats

Scientific Reports
The study aimed to determine the specific relative biological effectiveness (RBE) of various cells in the hippocampus following proton irradiation. Sixty Sprague–Dawley rats were randomly allocated to 5 groups receiving 20 or 30 Gy of proton or photon ...

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

Clinical 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 (
