Novel Means for Photoprotection

Frontiers in Medicine, 2018
Due to changes in human lifestyle (expanded sunbathing, the use of solaria, etc.) and, most importantly, increasing lifetime and thus higher cumulative exposure to solar radiation, skin aging and skin cancer have become major health issues.

Taxogenomic Characterization and Comparative Genomic Analysis of Hermanozyma buritii sp. nov., f.a., a Yeast Species Isolated From Plants and Soil

Yeast, EarlyView.
Isolation of the novel yeast species Hernanozyma buritii sp. nov. from soil and plant in Brazil, followed by phylogenetic characterization and genome analysis, highlighting its relationship with closely related taxa and genomic features associated with mating, pulcherriminic acid biosynthesis, and iron‐dependent pigmentation.

Within‐crown microclimatic variation and growth‐stage shape oak leaf chemistry with limited consequences for herbivore performance

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mature trees exhibit distinct vertical gradients in temperature and light. These within‐crown microclimatic gradients have been linked to spatial variation in leaf chemistry and herbivory.

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

Integrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

All-small-molecule Hydrogels for Safe and Efficient Photoprotection

Nature Communications
Long-term exposure to ultraviolet (UV) radiation can cause sunburn, skin aging, and skin cancers. Conventional sunscreens typically combine organic UV filters and inorganic particles for photoprotection, yet concerns remain regarding skin penetration ...

Amphibian‐Derived Peptide OA‐AL14 Alleviates UVB‐Induced Skin Photoaging via Autophagy Activation Mediated by the AMPK/mTOR Pathway

Integrative Zoology, EarlyView.
The schematic diagram illustrates that the amphibian‐derived peptide OA‐AL14 protects against UVB‐induced skin photoaging through a dual mechanism: activating the Nrf2 pathway to counteract oxidative stress and modulating the AMPK/mTOR axis to induce protective autophagy. ABSTRACT Skin photoaging, primarily driven by ultraviolet B (UVB) radiation, is a

Ecophysiological adjustments of a pine forest to enhance early spring activity in hot and dry climate

Environmental Research Letters, 2020
Climate change can impose large offsets between the seasonal cycle of photosynthesis and that in solar radiation and temperature which drive it. Ecophysiological adjustments to such offsets in forests growing under hot and dry conditions are critical for

Improving photoprotection: 4-Methylbenzylidene Camphor Microsphres

, 2015
We propose a new approach for photoprotection. 4-Methylbenzylidene camphor (4-MBC), one of the most widely used UV filters, was encapsulated in microspheres, with a view to overcoming problems (percutaneous absorption, photodegradation, lack of lasting ...

Enhancing the fastness characteristics of weld‐dyed cotton and recycled nylon 6,6 fabrics via sodium alginate and titanium dioxide

Coloration Technology, EarlyView.
Abstract This study investigates a sustainable dyeing and finishing strategy for recycled nylon 6,6 and organic cotton fabrics dyed with weld. Following meta‐mordant dyeing using alum under Natural Organic Dye Standard (NODS)‐compliant conditions, the fabrics were subjected to functional finishing with titanium dioxide as a multifunctional ...
