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.

Alleviation of photoaging‐associated MMP upregulation, prostanoid biosynthesis, and cell cycle arrest with titanium dioxide, zinc oxide, and inorganic‐only (ZnO + TiO2) sunscreens

Photochemistry and Photobiology, EarlyView.
Inorganic sunscreens containing the UV filters titanium dioxide (TiO2) and/or zinc oxide (ZnO) alleviated various biomarkers of photoaging in human dermal fibroblasts, at a gene and protein level. The study provides novel insights that observe the impact of inorganic photoprotection through the molecular biology of skin.

Ultrasonic Production of Nano-Size Dispersions and Emulsions [PDF]

, 2005
Ultrasound is a well-established method for particle size reduction in dispersions and emulsions. Ultrasonic processors are used in the generation of nano-size material slurries, dispersions and emulsions because of the potential in the deagglomeration ...

Possible involvement of keratinocyte‐derived microvesicle particles in human photosensitivity disorders

Photochemistry and Photobiology, EarlyView.
In this model, ROS generated by UVB result in PAFR agonists acting upon the PAFR resulting in MVP generation release via the enzyme aSMase. In photosensitivity, there are increased ROS, resulting in augmented PAF agonists and increased MVP release. This process can be blocked by aSMase inhibitors.

Effects of solar‐simulated (UVB plus UVA) radiation on the skin microbiome: An exploratory study

Photochemistry and Photobiology, EarlyView.
This exploratory in vivo study investigated the effects of solar‐simulated ultraviolet radiation (UVB plus UVA) on the human skin microbiome. Healthy male volunteers were exposed to suberythemal and erythemal UV doses, and skin microbiota were analyzed at multiple time points using flow cytometry‐based profiling and the open‐access bioinformatic ...

Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes

Photochemistry 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.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry 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 ...

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

An asset‐based model for fieldwork training workshops

Natural Sciences Education, Volume 55, Issue 1, June 2026.
Abstract Although conducting fieldwork is common for environmental scientists, not everyone feels welcomed or valued in field settings. This can result from a range of social and interpersonal challenges, including implicit bias, power dynamics, communication barriers, and mismatched expectations within research teams.
