DEVELOPMENT OF HIGH LEVEL AB INITIO METHODS TO DESCRIBE NONADIABATIC EVENTS AND APPLICATIONS TO THE EXCITED STATES OF SMALL BIOLOGICAL MOLECULES
… electron transfer mechanism to repair a nearby cyclobutane pyrimidine dimer (CPD). It is found that barriers on the anion S1 excited state surface prohibits easy access to conical intersections with the ground state, causing the anion to have a much longer excited state lifetime than the neutral …

Exploring the potential of UVC in treating superficial corneal infections
… analysis, to quantify DNA damage in the form of Cyclobutane Pyrimidine Dimer (CPD) formation. In the in vivo keratitis model, daily UVC exposure was assessed for treatment efficacy as well as safety, with regard to keratocyte number, inflammation and CPD formation. UVC effects were compared to …

Discovery of an extracellular stress sensory protein in Beauveria bassiana and identification of photolyase encoding phr-1 sequences in five entomopathogenic fungi
… region of the photolyase gene (phr-1), encoding cyclobutane pyrimidine dimer photolyase (CPD-PHR), an enzyme pivotal to DNA repair, was cloned, sequenced and identified for species of the genera Beauveria, Isaria, Lecanicillium, Metarhizium and Tolypocladium. The DNA and deduced amino acid …

Modulation of Cis-syn Cyclobutane Dimer Formation and Deamination at CpG sites by Nucleosome Particles and Its Implications for Deamination Bypass Mechanism for the Origin of C to T Mutations
… sites, which are also sites of preferential cyclobutane pyrimidine dimer: CPD) formation. CPDs containing C or 5-methylcytosine: mC) are not stable and spontaneously deaminate to U or T at pH 7 and 37°C over a period of hours or days. Deamination of Cs or mCs in CPDs is highly mutagenic …

Fréquence et distribution des dimères cyclobutyliques de pyrimidines suite à une exposition aux UV et évaluation de l’effet protecteur de l’acide sulfonique 2-phénylbenzymidazole-5
… du cancer cutané. Les dimères cyclobutyliques de pyrimidines (DCP) résultant d’une exposition aux UV sont considérés comme les principaux dommages à l’ADN impliqués dans la cancérogenèse cutanée. La fréquence des DCP et leur distribution entre les quatre types de sites dipyrimidiniques ont souvent …
