DNA damage in a solution containing copper(II) ions and ascorbic acid: Effect of the presence of sulfite
Autor: Thais Boscolo Requeijo, Silvia Helena Pires Serrano, Horacio Dorigan Moya
Publikováno v: Brazilian Journal of Pharmaceutical Sciences, Vol 57 (2021)
Some antioxidant compounds have a pro-oxidant effect in the presence of transition metal ions, due to the reduction of Mn+ to M(n-1)+ with simultaneous formation of free radicals, which then promote DNA damage. In the present study, we evaluated the

Study of DNA damage caused by dipyrone in presence of some transition metal ions
Autor: Bruna Corrêa Roriz, Horacio Dorigan Moya
Publikováno v: Saudi Pharmaceutical Journal, Vol 25, Iss 7, Pp 961-966 (2017)
The DNA damage in the presence of dipyrone (used as its sodium salt, NaDip) and some transition metal ions in an air saturated ([O2] ≈ 0.25 mM) non-buffered solution at T = (25.0 ± 0.5)°C was investigated by agarose gel electrophoresis. As metal

Estudo potenciométrico dos equilíbrios no sistema manganês (II) / azoteto
Autor: Horacio Dorigan Moya
Publikováno v: Biblioteca Digital de Teses e Dissertações da USPUniversidade de São PauloUSP.
Foram estudados os equilíbrios dos complexos de Mn (II) com íons azoteto, em meio aquoso, por método potenciométrico indireto, através de medidas de pH, em meio de azoteto 0 a 1,8 M, e a 25,0 ºC, utilizando força iônica 2,00 M mantida com per
