Electrochemical investigations on the capacity of flavonoids to protect DNA against damage caused by textile disperse dyes
(Elsevier B.V., 2014-03-01)
In previous work, the interaction of DNA with the textile dyes Disperse Orange 1 (DO1) and Disperse Red 1 (DR1), and their electrolysis products, resulted in significant changes in the characteristic oxidation peaks of the ...
Modelo vibro-rotacional para a molécula de DNA
(Universidade Estadual Paulista (Unesp), 2008-08-14)
O objetivo deste trabalho é investigar um modelo mecânico para a molécula de DNA. O modelo consiste de duas cadeias de osciladores harmônicos representando as tas do DNA. Esses osciladores são ligados por um potencial de ...

Electrochemistry of interaction of 2-(2-nitrophenyl)-benzimidazole derivatives with DNA
(2010)
In this study the interaction between new benzimidazole molecules, 2-(2-nitrophenyl)-1H-benzimidazole (NB) and N-benzoyl-2-(2-nitrophenyl)-benzimidazole (BNB), with dsDNA and ssDNA was assessed at pH 7.4. Using differential ...
The genotoxic effects of DNA lesions induced by artificial UV-radiation and sunlight
(ELSEVIER SCIENCE SA, 2010)
Solar radiation sustains and affects all life forms on Earth. The increase in solar UV-radiation at environmental levels, due to depletion of the stratospheric ozone layer, highlights serious issues of social concern. This ...
