Advances in organic UV filters for sunscreens over the past decade

open access: yesPhotochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

open access: yesPhotochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Development of chalcones structure‐related to avobenzone: Photoprotection, photostability, and safety evaluation

open access: yesPhotochemistry and Photobiology, EarlyView.
Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.

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

open access: yesPhotochemistry 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

A low‐cost handheld device for monitoring cutaneous photosensitivity

open access: yesPhotochemistry and Photobiology, EarlyView.
The cutaneous photosensitivity detection (CPD) device is a handheld contact‐based measurement device using 405 nm excitation and red fluorescence detection for monitoring skin phototoxicity risk after photodynamic therapy (PDT) procedures involving systemic aminolaevulinic acid (ALA) induced protoporphyrin IX (PpIX) photosensitization.

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

open access: yesPlant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.
