Feasibility of Urethra‐Sparing Ultra‐Hypofractionated Three‐Dose‐Level Radiotherapy for Prostate Cancer with a Dominant Intraprostatic Lesion Abutting the High‐Dose Avoidance Zone

Precision Radiation Oncology, EarlyView.
Ultra‐hypofractionated three‐dose‐level radiotherapy allows safe dose escalation to dominant intraprostatic lesions near the urethra while maintaining full coverage of pelvis and prostate and respecting urethral and organ‐at‐risk constraints. Abstract This planning study evaluated ultra‐hypofractionated three‐dose‐level radiotherapy for prostate cancer

Comprehensive database of track-structure simulations on DNA damage by H–Fe ions up to 1 GeV/u for space radiation biology

Scientific Reports
Understanding biological effects of high-charge, high-energy (HZE) particles is critical for evaluating health risks of long-duration deep-space missions. To complement the scarce experimental data, PARTRAC track-structure simulations are reported on DNA

Eurados intercomparisons in external radiation dosimetry: Similarities and differences among exercises for whole-body photon, whole-body neutron, extremity, eye-lens and passive area dosemeters

, 2016
The European Radiation Dosimetry Group (EURADOS) has been organising dosimetry intercomparisons for many years in response to an identified requirement from individual monitoring services (IMS) for independent performance tests for dosimetry systems. The

Optimal irradiation parameters for the development of the sterile insect technique in the seedcorn maggot Delia platura (Diptera: Anthomyiidae)

Pest Management Science, EarlyView.
X‐ray irradiation of Delia platura pupae showed that 20 Gy induces high sterility while maintaining male quality and competitiveness, establishing optimal parameters for sterile insect technique implementation in North America. Abstract BACKGROUND The seedcorn maggot, Delia platura Meigen (Diptera: Anthomyiidae), is a sporadic but economically ...

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by
