Ultraviolet radiation in the Atacama Desert

Antonie van Leeuwenhoek, 2018
The world's highest levels of surface ultraviolet (UV) irradiance have been measured in the Atacama Desert. This area is characterized by its high altitude, prevalent cloudless conditions, and a relatively low total ozone column. In this paper, we provide estimates of the surface UV (monthly UV index at noon and annual doses of UV-B and UV-A) for all ...

Perception and Signaling of Ultraviolet-B Radiation in Plants.

Annual Review of Plant Biology, 2021
Ultraviolet-B (UV-B) radiation is an intrinsic fraction of sunlight that plants perceive through the UVR8 photoreceptor. UVR8 is a homodimer in its ground state that monomerizes upon UV-B photon absorption via distinct tryptophan residues. Monomeric UVR8

Exposure to Ultraviolet Radiation in the Modulation of Human Diseases.

Annual Review of Pathology, 2019
This review focuses primarily on the beneficial effects for human health of exposure to ultraviolet radiation (UVR). UVR stimulates anti-inflammatory and immunosuppressive pathways in skin that modulate psoriasis, atopic dermatitis, and vitiligo ...

A Standard for Ultraviolet Radiation

Applied Optics, 1973
Photoemission diode standards for accurately measuring monochromatic ultraviolet light intensity (3000 A-11OO A) are described that are also blind to visible ligh (lambda> 3600 A). The standard uses an opaque photocathode of Cs(2)Te and is unique because of its combination of thinness (19 mm), high sensitivity (Q.E.

Methotrexate and Ultraviolet Radiation

Archives of Dermatology, 1982
Reactivation of a sunburn has been reported after the administration of methotrexate for cancer chemotherapy. A similar reaction is described in a patient with psoriasis who was receiving both coal tar with ultraviolet radiation for cutaneous lesions and methotrexate for arthritis.

Effects of Ultraviolet Radiation

Medical Clinics of North America, 1990
Ultraviolet radiation from high-intensity sources has well-known acute effects on the eye and skin, consisting primarily of photokeratoconjunctivitis and sunburn, which are enhanced in the presence of photosensitizing agents. Long-term elevated exposure to low-level ultraviolet radiation is also responsible for an increased risk of squamous- and basal ...

Ultraviolet Radiation and Psoriasis

Archives of Dermatology, 1972
The macroscopic and microscopic reactions of nonpsoriatic and clinically uninvolved psoriatic skin to ultraviolet radiation (UVR) showed no gross differences. The erythema threshold was decreased in subjects whose psoriasis was in an acute, eruptive stage.
