Phototherapy (UVA and UVB)Phototherapy or light therapy uses specific wavelengths of light in the ultraviolent (UV) range to treat certain skin disorders. Ultraviolent light has anti-inflammatory properties in the skin and can be used to decrease skin inflammation and decrease skin itching. It can...
UVA testing uses ultraviolet light with a wavelength of 320-400 nanometers, while UVB testing uses ultraviolet light with a wavelength of 280-320 nanometers. The relationship between UVA testing and UVB testing mainly reflects the different effects of different wavelengths of ultraviolet radiation on...
Among all wavelengths of ultraviolet rays, only short wave ultraviolet UVC has the function of sterilization and disinfection. It belongs to a pure physical disinfection method. It has the characteristics of broad spectrum, high efficiency, fast and complete, no need to add chemical agents, no dru...

A non-dimer type of DNA damage does not appear to play a major role in either UVA or UVB mutagenesis. Therefore, the previously reported increasing mutagenicity per dimer with increasing wavelengths cannot be due to non-dimer DNA damage. Differences in the cellular response to UVA and UVB, ...
The responses of the autochthonous soil and aquatic organism, Pseudomonas aeruginosa to UV radiation wavelengths (UVA, 320-400 nm, and UVB, 280-320 nm) has been investigated in this study. P. aeruginosa recA mutants were found to be more sensitive to both UVA and UVB radiation than were the...
The majority of the resulting wavelengths were in the UVB (290–320 nm; above 90%) and UVA (less than 10%) range and the peak emission was recorded at 314 nm. The mice were irradiated for 7 days, 2 h/day, with a daily dose of 1.9 J/cm2. 2.8. Assessment of ...
(General Physics) the part of the electromagnetic spectrum with wavelengths shorter than light but longer than X-rays; in the range 0.4 × 10–6and 1 × 10–8metres adj (General Physics) of, relating to, or consisting of radiation lying in the ultraviolet:ultraviolet radiation. Abbreviation:...
The metabolic profile of the rabbit lenses showed no detectable changes after UVA or UVB exposure.The combination of HR-MAS (1)H NMR spectroscopy and multivariate methods proved effective to analyse intact corneal and lens tissue after exposure to UV radiation of different wavelength...
Most of UVB and all of UVC (wavelengths below 280 nm) are removed by the ozone layer and these shorter wavelengths are not present in incident sunlight. UVA is classified as “probably carcinogenic to humans” by WHO IARC [1] although, unlike UVC and UVB, it is absorbed poorly by ...
