LED (Light-Emitting Diodes) generate curing energy using an array of surface-mounted LEDs instead of traditional metal halide or mercury bulbs. They are semiconductor energy sources that emit very discrete wavelengths of energy, resulting in a single, narrow, bell-shaped em...
Therefore, G2/M arrest and apoptotic resistance are the major differences observed between UACC903 and UACC903(+6) cell lines in response to the UVC treatment. The UVC-induced UACC903 G2/M arrest is reminiscent of a recent report that all of UVA (400 – 320 nm), UVB (320 – 290 nm...
UVC and to a lesser extend UVB photons are directly absorbed by DNA bases, generating their excited states that are at the origin of the formation of pyrimidine dimers. UVA (and visible) light by interaction with endogenous or exogenous photosensitizers induce the formation of DNA damage through ...
The aim of this study was to determine the effect of rutin on interactions between membrane phospholipid and antioxidant proteins expression in UVA or UVB irradiated fibroblasts. Following exposure to UVA and UVB irradiation cells were incubated with rutin 12h before and/or up to 24h after ...
It is divided into the following: UVA, 315–380 nm; UVB, 280–315 nm; and UVC, 100–280 nm. All UV ranges have a disinfecting effect. The UVC range from 200 to 280 nm exhibits by far the highest antimicrobial and antiviral efficacy, as these wavelengths are in the range where ...
