TGF-β signaling links E-cadherin loss to suppression of nucleotide excision repair. [PDF]

open access: yes, 2016
E-cadherin is a cell adhesion molecule best known for its function in suppressing tumor progression and metastasis. Here we show that E-cadherin promotes nucleotide excision repair through positively regulating the expression of xeroderma pigmentosum ...

Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens

open access: yesAdvanced Healthcare Materials, EarlyView.
High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Biology and Natural Sources of Vitamin D

open access: yesMehmet Akif Ersoy Üniversitesi Fen Bilimleri Enstitüsü, 2020
Vitamin D deficiency and insufficiency are among the important health problems worldwide. Vitamin D, which is synthesized by sun exposure (specific wavelength ultraviolet UVB rays), is known to act as a natural protector, preventing and delaying many ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

GSDME deficiency leads to the aggravation of UVB-induced skin inflammation through enhancing recruitment and activation of neutrophils

open access: yesCell Death and Disease, 2022
Gasdermin E (GSDME)-mediated pyroptosis is induced in keratinocytes of UVB-challenged skin. The role of GSDME in UVB-caused skin damage remains unknown. To explore the role of GSDME in UVB-induced skin inflammation.

The response of bacterial community to UVB was significantly different between immature periphyton and mature periphyton, but not for physiological indicators

open access: yesEcotoxicology and Environmental Safety, 2022
Periphyton has important ecological functions. It can even exist in environments with strong ultraviolet radiation. However, knowledge of periphyton under ultraviolet is limited, which limits the understanding and application of periphyton in ...

Escape fraction of ionizing photons from high-redshift galaxies in cosmological SPH simulations

open access: yes, 2010
Combing the three-dimensional radiative transfer (RT) calculation and cosmological SPH simulations, we study the escape fraction of ionizing photons (f_esc) of high-redshift galaxies at z=3-6.

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 ...
