UV-A and UV-B combined with photosynthetically active radiation change plant growth, antioxidant capacity and essential oil composition of Pelargonium graveolens

open access: yesBMC Plant Biology, 2023
Background The different wavelengths of solar radiation incident on earth [herein: Photosynthetically Active Radiation (PAR) , Ultra Violet-A (UV-A) and Ultra Violet-B (UV-B)] and their spectral balance not only have an impact on plants’ growth ...

Photomorphogenic responses to ultraviolet‐B light [PDF]

open access: yesPlant, Cell & Environment, 2017
AbstractExposure to ultraviolet B (UV‐B) light regulates numerous aspects of plant metabolism, morphology and physiology through the differential expression of hundreds of genes. Photomorphogenic responses to UV‐B are mediated by the photoreceptor UV RESISTANCE LOCUS8 (UVR8).

Ultraviolet Radiation From a Plant Perspective: The Plant-Microorganism Context

open access: yesFrontiers in Plant Science, 2020
Ultraviolet (UV) radiation directly affects plants and microorganisms, but also alters the species-specific interactions between them. The distinct bands of UV radiation, UV-A, UV-B, and UV-C have different effects on plants and their associated ...

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

open access: yesMarine 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.

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

open access: yesHealth 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.

Sensitivity of Rice to Ultraviolet-B Radiation [PDF]

open access: yesAnnals of Botany, 2006
Depletion of the stratospheric ozone layer leads to an increase in ultraviolet-B (UVB: 280-320 nm) radiation reaching the earth's surface, and the enhanced solar UVB radiation predicted by atmospheric models will result in reduction of growth and yield of crops in the future.

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

open access: yesDermatologica 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

open access: yesJournal 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 ...
