Reactive Oxygen Species as Central Coordinators of Organelle Stress and Tumor Radiosensitivity

Cell Biochemistry and Function, Volume 44, Issue 10, October 2026.
ABSTRACT Radiotherapy is a major modality for cancer treatment, but therapeutic responses vary substantially across tumor types and patients. Beyond direct DNA damage, radiation‐induced reactive oxygen species (ROS) are increasingly recognized as dynamic regulators of cellular stress responses.

Neutron-gamma flux and dose calculations in a Pressurized Water Reactor (PWR)

EPJ Web of Conferences, 2017
The present work deals with Monte Carlo simulations, aiming to determine the neutron and gamma responses outside the vessel and in the basemat of a Pressurized Water Reactor (PWR). The model is based on the Tihange-I Belgian nuclear reactor. With a large

Radiotherapy‐Induced Side Effects: Epidemiology, Pathogenesis, Prevention and Treatments

MedComm, Volume 7, Issue 10, October 2026.
Radiotherapy for malignancies frequently injures the organs’ systems through oxidative stress, fibrosis, inflammation, and vascular damage. This review systematically maps the epidemiology, pathogenesis, and emerging therapies to propose a mechanism‑network‑targeted framework for integrated, personalized care in radiation oncology.

Inhalable ROS‐Responsive Nanospray Activates PPAR‐γ to Restore Macrophage Mitochondrial Homeostasis and Attenuate Radiation‐Induced Lung Injury

Advanced Science, Volume 13, Issue 54, 28 September 2026.
A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.

Presentation and first outcomes of the FIGARO research program that aims at assessing the airborne release fraction of plutonium dioxide during glove box fires in nuclear fuel fabrication and reprocessing plants

Mechanical Engineering Journal
Fires in nuclear fuel fabrication and reprocessing plants can cause the rupture of the glove box (GB) containment with a risk of dispersion of plutonium dioxide (PuO2) within the facility.

Prenatal low-dose cesium-137 exposure combined with a lipid-enriched diet promotes late-onset hepatic tumorigenesis in male mouse offspring

Scientific Reports
Intrauterine life represents a sensitive period during which low‑dose radiation may shape long‑term health outcomes; however, its impact, particularly when combined with lifelong metabolic stressors such as a high‑fat diet (HFD) remains unclear.

PD‐L1 in Ovarian Cancer: Immune Evasion, Tumor‐Intrinsic Signaling, and Chemoresistance

Cancer Medicine, Volume 15, Issue 9, September 2026.
The “Dual Shield” model of PD‐L1 in ovarian cancer. On the outside, PD‐L1 engages PD‐1 to inactivate T cells and drive immune evasion (immune shield). Inside the tumor cell, PD‐L1 activates AKT–mTOR, enhances DNA repair, rewires metabolism, supports autophagy, and enforces stemness programs—collectively creating a chemoresistance shield.
