Bat eyes have ultraviolet-sensitive cone photoreceptors [PDF]

, 2009
Mammalian retinae have rod photoreceptors for night vision and cone photoreceptors for daylight and colour vision. For colour discrimination, most mammals possess two cone populations with two visual pigments (opsins) that have absorption maxima at short

Proxy reconstruction of ultraviolet-B irradiance at the Earth's surface, and its relationship with solar activity and ozone thickness [PDF]

, 2019
Solar ultraviolet-B (UV-B) irradiance that reaches the Earth’s surface acts as a biotic stressor and has the potential to modify ecological and environmental functioning.

Melanoma induction by ultraviolet A but not ultraviolet B radiation requires melanin pigment [PDF]

Nature Communications, 2012
Malignant melanoma of the skin (CMM) is associated with ultraviolet radiation exposure, but the mechanisms and even the wavelengths responsible are unclear. Here we use a mammalian model to investigate melanoma formed in response to precise spectrally defined ultraviolet wavelengths and biologically relevant doses.

Photostability of TiO2-Coated Wool Fibers Exposed to Ultraviolet B, Ultraviolet A, and Visible Light Irradiation

AUTEX Research Journal, 2021
This study is to investigate the role of the coating of TiO2 nanoparticles deposited on wool fibers against high-intensity ultraviolet B (UVB), ultraviolet A (UVA), and visible light irradiation.

Protective Effects of Fucoxanthin on Ultraviolet B-Induced Corneal Denervation and Inflammatory Pain in a Rat Model

Marine Drugs, 2019
Fucoxanthin is a carotenoid with many pharmaceutical properties that is found in brown seaweed. However, the effects of fucoxanthin on corneal innervation and intense eye pain have not been extensively examined.

Effects of high and low irradiance excimer light in repigmenting vitiligo: A single-center cross-sectional study

Dermatologica Sinica
Ultraviolet B (UVB) phototherapy is an important treatment modality for inducing repigmentation in vitiligo. Wavelength and fluence (dose; J/m2) are well-recognized parameters influencing phototherapy outcomes. Irradiance (power density; W/m2), the total

UVA and Seasonal Patterning of 56 370 Myocardial Infarctions Across Scotland, 2000–2011

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Myocardial infarction exhibits seasonal patterning, with higher amplitude at increased latitude. Epidemiological evidence suggests that sunlight is protective against cardiovascular disease, independent of ambient temperature, but ultraviolet ...

Home-based narrowband UVB, topical corticosteroid or combination for children and adults with vitiligo: HI-Light Vitiligo three-arm RCT

Health Technology Assessment, 2020
Background: Systematic reviews suggest that narrowband ultraviolet B light combined with treatments such as topical corticosteroids may be more effective than monotherapy for vitiligo.
