Application of the Linear-Quadratic model to targeted radionuclide therapy [PDF]
, 2011 PhDThe principal aim of this work was to test the hypothesis that the Linear-Quadratic (LQ) model of cell survival, developed for external beam radiotherapy (EBRT), could be extended to targeted radionuclide therapy (TRT) in order to predict dose ...

Photochemistry and Photobiology, EarlyView.Exposure to ultraviolet radiation (UV‐R) from tanning equipment increases skin cancer risk through molecular changes, but genomic thresholds remain unclear. Using mice, we examined dose‐ and time‐dependent gene expression after erythemally‐weighted UV‐R doses (0–40 mJ/cm2).

Photochemistry and Photobiology, EarlyView.Photoproducts of the photosensitizer protoporphyrin IX (PpIX) may have diagnostic and therapeutic relevance in photodynamic diagnosis (PDD) and photodynamic therapy (PDT). These photoproducts possess fluorescence and photosensitizing properties and could serve as a complementary dosimetry index alongside photosensitizer photobleaching. The formation of

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

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

Advanced Oncology, Volume 1, Issue 1, December 2026.ABSTRACT The avian eggshell is a sophisticated, multi‐functional biocomposite and, more importantly, an autonomous life‐support system evolved to safeguard embryonic development across dynamic and hostile environments. Discussing eggshell‐inspired biomaterials beyond simple structural imitation, this review translates these evolutionary survival ...
