Revisiting the Temperature Dependence of the Photorespiratory CO2 Compensation Point (Γ*)

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Accurate estimation of the photorespiratory CO2 compensation point (Γ*) is essential for describing the balance between Rubisco carboxylation and oxygenation and for parameterising biochemical models of photosynthesis. Γ* and the rate of CO2 release in the light (DL) are commonly estimated using the Laisk method, based on measurements of net ...

Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

Evaluating tools for predicting and measuring radiometric performance of germicidal ultraviolet systems

open access: yesPhotochemistry and Photobiology, EarlyView.
An evaluation of simulation and measurement tools for germicidal ultraviolet (GUV) systems is presented to inform their design and deployment to control the spread of airborne pathogens. Abstract Germicidal ultraviolet (GUV) air treatment technologies can be effective and safe for reducing airborne disease transmission.

Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes

open access: yesPhotochemistry and Photobiology, EarlyView.
Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

open access: yesPhotochemistry and Photobiology, EarlyView.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...
