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.

Ultraviolet B but not Ultraviolet A Radiation Initiates Melanoma [PDF]
Cancer Research, 2004 Abstract Cutaneous malignant melanoma is one of the fastest increasing cancers with an incidence that has more than doubled in the last 25 years. Sunlight exposure is strongly implicated in the etiology of cutaneous malignant melanoma and the UV portion of the sunlight spectrum is considered responsible. Data are, however, conflicting on

Voriconazole N‐oxide and its ultraviolet B photoproduct sensitize keratinocytes to ultraviolet A [PDF]
British Journal of Dermatology, 2015 The antifungal agent, voriconazole, is associated with phototoxicity and photocarcinogenicity. Prior work has indicated that voriconazole and its hepatic N-oxide metabolite do not sensitize keratinocytes to ultraviolet B (UVB). Clinical observations have suggested that ultraviolet A (UVA) may be involved.To determine the photochemistry and photobiology

Optogenetic tools controlled by ultraviolet-B light [PDF]
aBIOTECH, 2021 AbstractDecades of genetic, molecular and biochemical studies in plants have provided foundational knowledge about light sensory proteins and led to their application in synthetic biology. Optogenetic tools take advantage of the light switchable activity of plant photoreceptors to control intracellular signaling pathways. The recent discovery of the UV-

Response of conifers to UV-B and climate in mountain areas [PDF]
Global Journal of Environmental Science and Management, 2018 The present study was focused to examine the combined effects of climate and ultraviolet-B radiation on conifer tree-ring density. Statistical methods were employed to extract tree responses in annual ring density and to identify functional relationship ...

Low Fluence Ultraviolet-B Promotes Ultraviolet Resistance 8-Modulated Flowering in Arabidopsis
Frontiers in Plant Science, 2022 Ultraviolet-B (UV-B) irradiation (280–320 nm) is an integral part of sunlight and a pivotal environmental cue that triggers various plant responses, from photoprotection to photomorphogenesis and metabolic processes.

Sensitivity of Rice to Ultraviolet-B Radiation [PDF]
Annals 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.

Journal of the Indian Academy of Geriatrics, 2019 Background: Skin diseases can be one of the factors affecting the quality of life of the growing elderly population. In treating various dermatoses in the elderly, structural and physiological changes of the skin due to ageing need to be considered ...
