New challenges in high-energy particle radiobiology

, 2014
Densely ionizing radiation has always been a main topic in radiobiology. In fact, a-particles and neutrons are sources of radiation exposure for the general population and workers in nuclear power plants. More recently, high-energy protons and heavy ions

Lnc1267-hnRNP U interaction promotes radioresistance by inhibiting apoptosis via attenuated RelA/p65 Ser536 phosphorylation

Cellular and Molecular Life Sciences
Radiotherapy efficacy is frequently limited by tumor radioresistance, with dysregulated apoptosis playing a pivotal role. While NF-κB is a well-established mediator of cancer radioresistance (primarily through anti-apoptotic mechanisms), the paradoxical ...

Estimation of Maximum Obtainable RBE ‘Turnover-Points’ (LET_U) for Accelerated Ions Based on a Nuclear Charge Radius Hypothesis to Obtain Iso-Effective LET and RBE Values

Biophysica
Purpose: The purpose of this study is to analyze the relationship between nuclear charge (Z), atomic mass (A), LET (linear energy transfer for maximal relative biological effectiveness (RBE)) for accelerated ions based on the hypothesis that for each ion,

THE RADIOBIOLOGICAL PLATFORM AT ARRONAX

Radiation Protection Dosimetry, 2019
The cyclotron ARRONAX can deliver different types of particles (protons, deuterons, alpha-particles) in an energy range up to 68 MeV. One of its six experimental halls is dedicated to studying the interactions of radiation with matter including living matter. A horizontal beamline for cell irradiation has been setup and characterized.

Immune Modulation Through Stereotactic Radiotherapy: The Role of TBX21, GATA-3, FoxP3, and RORɣt

Medicina
Background and Objectives: Stereotactic radiotherapy enhances local tumor control by delivering high doses directly to the tumor. It is thought to activate the immune system via T-cells, possibly creating a systemic response.

Late Age- and Dose-Related Effects on the Proteome of Thyroid Tissue in Rats after ¹³¹I Exposure

Radiation
The physiological process of iodine uptake in the thyroid is used for 131I treatment of thyroid diseases. Children are more sensitive to radiation compared to adults and may react differently to 131I exposure.
