Quantifying Population Reversibility of Sensor Performance in Multi‐Cycle Single‐Sensor Recovery Assay

Small, EarlyView.
Single‐walled carbon nanotubes (SWCNTs) are versatile optical nanosensors that can be imaged at the single‐sensor level to map biological processes. To translate such imaging into calibrated measurements, sensor recovery under repeated analyte exposures must be analyzed.

Effectiveness of dietary supplements for skin photoaging in healthy adults: a systematic review and meta-analysis of randomized controlled trials

Frontiers in Medicine
BackgroundThe dietary supplement industry offers a wide range of orally consumed products that claim to combat skin photoaging, however, there is a lack of research on the proof of safety and effectiveness of dietary supplements in anti-skin photoaging ...

Heat-Killed Lacticaseibacillus paracasei Ameliorated UVB-Induced Oxidative Damage and Photoaging and Its Underlying Mechanisms

Antioxidants, 2022
Ultraviolet B (UVB) radiation is a major environmental causative factor of skin oxidative damage and photoaging. Lacticaseibacillus paracasei is a well-known probiotic strain that can regulate skin health.

A Novel Antioxidant Peptide Cath‐Np Derived from Nanorana parkeri Attenuates UVB‐Induced Skin Photodamage in Mice

Integrative Zoology, EarlyView.
Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Photoaging in Asians [PDF]

Photodermatology, Photoimmunology & Photomedicine, 2003
The aging process of the skin can be divided into intrinsic and photoaging. Clinically, naturally aged skin is smooth, pale and finely wrinkled. In contrast, photoaged skin is coarsely wrinkled and associated with dyspigmentation and telangiectasia. Although the population of Asia is more than half the population of the Earth, no well‐designed study ...

Demographic Analysis of the Sun Protective Behaviours and Skin Cancer Risk of Victorian Farmers

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Background Farmers have an elevated risk of melanoma and non‐melanoma skin cancer due to their occupational exposure to high levels of ultraviolet radiation. The sun protective behaviours of farmers are poorly understood, limiting targeted interventions to this at‐risk population.

Resveratrol activates autophagy and protects from UVA-induced photoaging in human skin fibroblasts and the skin of male mice by regulating the AMPK pathway

Biogerontology (Dordrecht)
Skin photoaging is mostly caused by ultraviolet A (UVA), although active medications to effectively counteract UVA-induced photoaging have not yet been created.

Resveratrol Treats UVB-Induced Photoaging by Anti-MMP Expression, through Anti-Inflammatory, Antioxidant, and Antiapoptotic Properties, and Treats Photoaging by Upregulating VEGF-B Expression

Oxidative Medicine and Cellular Longevity, 2022
UVB exposure is one of the primary factors responsible for the development of photoaging, and the aim of this study was to investigate the mechanism involved in the photoprotective properties of resveratrol (RES) in UVB‐induced photoaging.
