Characterization of DNA-repair potential in deep subsurface bacteria challenged by UV light, hydrogen peroxide, and gamma radiation
… radiation in its natural habitat. Evidence for photoreactivation and the presence of an SOS-like mechanism was also detected in subsurface bacteria. The presence of UV resistance and photoreactivation in subsurface bacteria that have been shielded from solar radiation for millions of years may …

An investigation into the use of High-Intensity Narrow Spectrum light as a decontamination technology
… PUV-damaged S. aureus cells can undergo photoreactivation upon exposure to 300-500-nm light, with maximum effect elicited at 360-380 nm. This photoreactivation potential, that can affect the inactivation capability of UV-light decontamination technologies, was not found to be associated …

Effects of light and temperature on the formation of sexual structures in the family Saprolegniaceae
… indicated physiological strain differences. Photoreactivation was demonstrated in S. ferax and both isolates of S. parasitica. Evidence was shown that light caused production of toxic substances in the medium which caused inhibition of growth and sporulation. The blue peroxychromic test for …

UVB vermittelte DNA-Schäden und Immunsuppression in humanen dendritischen Zellen
Es gibt Hinweise, daß die durch UVB-Strahlung beeinflusste Funktion von antigenpräsentierenden Zellen (APZ), d.h. LZ in der Haut, mit UVB induzierten DNA-Schäden in Zusammenhang stehen. <br>In dieser Arbeit sollte geklärt werden, ob die durch UVB-Strahlung induzierte Hemmung der …
