Cis‐urocanic acid formation following far‐UVC exposure and associated signaling responses in keratinocytes

Photochemistry and Photobiology, EarlyView.
Far‐UVC (200–235 nm) has emerged as a safe and effective indoor disinfection tool, but effects on skin immunomodulation remain unclear. This study demonstrates that 222 nm far‐UVC converts trans‐urocanic acid (UCA) to its biologically active cis isomer at levels comparable with solar radiation. In keratinocytes, far‐UVC alone caused modest increases in

In vivo dosimetry in total body irradiation

Nucleus, 2019
Total Body Irradiation (TBI) is a radiotherapy technique that consists of irradiating homogeneously the whole patient’s body and it is characterized by an extended source to surface distances and the use of large irradiation fields.

The effect of photodynamic therapy in head and neck cancer: A comprehensive review of in vivo models

Photochemistry and Photobiology, EarlyView.
This review evaluates Photodynamic Therapy (PDT) in in vivo head and neck cancer models. PDT effectively generates ROS, reducing tumor growth, cell proliferation and angiogenesis while enhancing survival and immune responses. However, methodological heterogeneity highlights the urgent need for standardized dosimetric protocols to ensure reproducibility

Chemical Exposures, DNA Methylation and Whole Blood DNA Damage in Pet Golden Retrievers

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Canine multicentric lymphoma (CL) is a common and typically fatal cancer among dogs. Although certain breeds have a higher incidence of CL, its environmental risk factors remain uncertain. Exposures to herbicides and volatile organic compounds (VOCs) associate with non‐Hodgkin lymphoma in people.

Photobiomodulation restores blood–brain barrier integrity after hypoxia via endothelial von Willebrand factor modulation in a humanised tricellular transwell model

The Journal of Physiology, EarlyView.
Abstract figure legend Photobiomodulation restores blood–brain barrier (BBB) integrity following hypoxic stress. A multicellular human BBB model comprising brain microvascular endothelial cells, astrocytes and pericytes was established in a transwell system and subjected to acute hypoxia.

Improving image quality in terbium‐161 phantom imaging: Quantitative evaluation of DEW and TEW scatter correction methods

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Terbium‐161 (Tb‐161) emits gamma rays and beta radiation, enabling both therapeutic and imaging applications. However, the multiple gamma emissions of 161Tb can affect image quality by increasing the scattering rate during SPECT imaging.

Synthetic CT‐enabled weekly adaptive radiotherapy for nasopharyngeal carcinoma: Optimizing plan adaptation triggers through volumetric–dosimetric monitoring

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background and purpose Anatomical changes during radiotherapy for nasopharyngeal carcinoma (NPC) frequently compromise target volume coverage while escalating dose delivery to organs at risk (OARs). In adaptive radiotherapy (ART), optimizing workflow efficiency to minimize clinical workload while maximizing patient benefit remains a ...

Real‐time motion tracking of a gold implant in water by Cherenkov lights

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background The intra‐fraction motion of tumors during radiation therapy can be monitored using imaging systems based on X‐ray imaging (e.g., kV/MV radiography or CBCT) or magnetic resonance imaging (MRI). However, these techniques have limitations, including additional ionizing radiation dose and the need for complex, expensive equipment ...

Feasibility study: Use of an optical scanning system to obtain 3D body surface images suitable for total skin electron therapy treatment dosimetry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Total skin electron therapy (TSET, also known as TSE, TSI, TSEI or TSEBT) provides an effective treatment for extensive superficial lesions such as mycosis fungoides, although the standing setups and large distances used for treatment mean that comprehensive three‐dimensional (3D) dose calculations are rarely achievable clinically ...
