Therapeutic effect of NEO400, perillyl alcohol conjugated to linoleic acid, in a mouse model of UV‐induced skin damage

Photochemistry and Photobiology, Volume 101, Issue 2, Page 338-349, March/April 2025.
In the present work with mouse models, we demonstrate that a novel compound, NEO400, is able to profoundly protect skin against damage caused by UV radiation (UVR) when it is applied to skin post‐UVR exposure. In comparison, Aloe vera or linoleic acid are unable to achieve a similar level of protection.

Probing skin photoallergens in reconstructed human epidermis: An EPR spin trapping investigation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 275-281, March/April 2025.
We present an original proof‐of‐concept methodology to probe radical generation from allergens in contact with photoexposed skin, using electron paramagnetic resonance and spin trapping in a reconstructed human epidermis model mimicking real‐life exposure scenarios.

Spectroscopic analysis of bacterial photoreactivation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.
This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

Apoptosis kinetics of purified and PBMC‐associated lymphocytes after photopheresis‐like 8‐methoxypsolaren/UVA treatment

Photochemistry and Photobiology, EarlyView.
Extracorporeal photopheresis (ECP) induces apoptosis in circulating immune cells, but its kinetics vary slightly depending on the cell type. We compared the progression of apoptosis in PBMCs versus highly purified T cells exposed to 8‐methoxypsoralen and ultraviolet A.

Exploring natural sunscreens: UVB protection and antioxidant properties in gadusol‐rich fish roes extracts

Photochemistry and Photobiology, EarlyView.
Gadusol‐rich extracts provide effective UVB protection and antioxidant activity in HaCaT cells and C. elegans, highlighting their potential as natural photochemoprotective agents for pharmaceutical and cosmetic applications. It also demonstrates remarkable in vitro antioxidant capacity and thermal stability over time.
