UVA Radiation Is Beneficial for Yield and Quality of Indoor Cultivated Lettuce

Frontiers in Plant Science, 2019
Understanding the wavelength dependence of plant responses is essential for optimizing production and quality of indoor plant cultivation. UVA is the main component of solar UV radiation, but its role on plant growth is poorly understood.

Metformin Attenuates UVA-Induced Skin Photoaging by Suppressing Mitophagy and the PI3K/AKT/mTOR Pathway

International Journal of Molecular Sciences, 2022
Ultraviolet (UV) radiation is a major cause of photoaging that can induce DNA damage, oxidative stress, and cellular aging. Metformin (MF) can repair DNA damage, scavenge reactive oxygen species (ROS), and protect cells.

Chlorogenic Acid Prevents UVA-Induced Skin Photoaging through Regulating Collagen Metabolism and Apoptosis in Human Dermal Fibroblasts

International Journal of Molecular Sciences, 2022
Skin aging is categorized as chronological aging and photo-aging that affected by intrinsic and extrinsic factors. The present study aimed to investigate the anti-aging ability and its underlying mechanism of chlorogenic acid (CGA) on human dermal ...

Biowaste Management: Banana Fiber Utilization for Product Development

Journal of Natural Fibers, 2022
Banana is a crop that is primarily cultivated for its fruit, mainly in the tropical countries of the world. After harvesting, nearly 60% of its biomass including pseudostems are being left as a waste.

UVA Radiation, DNA Damage, and Melanoma

ACS Omega, 2022
Melanoma is a lethal type of skin tumor that has been linked with sunlight exposure chiefly in fair-skinned human populations. Wavelengths from the sun that can reach the earth’s surface include UVA radiation (320–400 nm) and UVB radiation (280–320 nm ...

Human UVA exposures estimated from ambient UVA measurements [PDF]

Photochemical & Photobiological Sciences, 2003
The methods presented in this paper allow for the estimation of human UVA exposure using measured UVA irradiance values. Using measured broadband UVA irradiances over the period of a year, it was estimated that for humans in an upright posture and not moving the head with respect to the body, the nose received 26.5% of the available ambient UVA ...

The Photomorphogenic Transcription Factor PpHY5 Regulates Anthocyanin Accumulation in Response to UVA and UVB Irradiation

Frontiers in Plant Science, 2021
Red coloration contributes to fruit quality and is determined by anthocyanin content in peach (Prunus persica). Our previous study illustrated that anthocyanin accumulation is strongly regulated by light, and the effect of induction differs according to ...
