Long‐Term Human Skin Platform for Modeling Chronic Inflammation, Environmental Stress, and Therapeutic Intervention

open access: yesAdvanced Science, EarlyView.
An advanced, long‐term human skin platform maintains native skin structure and key tissue functions for up to four weeks. The platform models chronic inflammation, aging‐related skin changes, and UVB damage, enabling drug and topical interventions—including anti‐inflammatory therapy, senolytic treatment, and sunscreen—to be evaluated in intact human ...

Skin photoageing: mechanisms of development and particular features of clinical manifestations

open access: yesVestnik Dermatologii i Venerologii, 2017
The article discloses current concepts of mechanisms of development of skin photoageing caused by UV irradiation (UVA and UVB). Chronic exposure of skin to UV irradiation results in damage of genome DNA, development of DNA mutations, damage of proteins ...

The effect of clouds on enhancing UVB irradiance at the earth's surface: a one year study

open access: yes, 2000
The most extensive study of frequency, magnitude and sky properties associated with UVB enhancement is reported. The first integrated automatic sky camera and irradiance measurement system was used for simultaneous data collection over the solar zenith ...

Role of SoxE transcription factors in development and disease

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

FeIII‐Mediated Synthesis of Azaspirodienones via Ipso‐Radical Cyclization of Ugi–4CR Adducts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An efficient two‐step protocol for the synthesis of azaspirodienones via Fe‐mediated ipso‐radical cyclization of Ugi adducts has been developed. This methodology provides rapid access to these privileged spirocyclic architectures under mild conditions, offering a practical and versatile approach to generating structurally complex molecules with ...

Photoadaptation of the skin during exposure to narrowband ultraviolet b radiation [PDF]

open access: yes, 2000
The aim of this study is to determine the rate at which UVB radiation takes effect in order to produce an effective regimen for treatment. Psoriasis, a chronic, proliferative, inflammatory disease that is under genetic and environmental control is the ...

Organic photonic synaptic transistors for bionic vision: From spectral engineering to flexible intelligent perception

open access: yesFlexMat, EarlyView.
Different wavelength photonic synapses are used for biomimetic visual applications. Abstract Bionic intelligent visual perception systems have significant application prospects in fields such as autonomous driving and robotics, medical imaging and auxiliary diagnosis, security and monitoring.

LXRα and PPARα Mediated Hepatic Lipid Metabolic Disruption Induced by the UV Filter EHMC in 2D and 3D HepaRG Cell Models

open access: yesFood Safety and Health, EarlyView.
Dietary UV filter EHMC induces hepatic steatosis in HepaRG cells at noncytotoxic concentrations. Mechanistically, EHMC binds nuclear receptors (LXRα, PPARα), upregulating SREBP‐1 to accelerate fatty acid synthesis. These findings highlight the potential metabolic toxicity of widespread EHMC exposure through food sources.

Broadband UVB revisited: Is the narrowband UVB fad limiting our therapeutic options?

open access: yesJournal of Dermatological Treatment, 2009
Broadband ultraviolet B (BB-UVB) phototherapy has demonstrated efficacy in the treatment of cutaneous disorders including psoriasis, atopic dermatitis, uremic pruritus and idiopathic pruritus. In the last decade, there has been a rapidly escalating process of replacing BB-UVB phototherapy units with narrowband ultraviolet B (NB-UVB) equipment, as ...
