1. Efeitos de raios-X de baixa energia em células mamárias / Effects of low energy x-rays in mammary cells
Radiation doses of low-energy can induce double-stranded breaks in DNA as well resulting in altered profiles of gene expression related to these injuries. The damage is not repaired or poorly repaired leading to increased susceptibility to oncogenic transformation since most important biological effects caused by ionizing radiation are mutation and carcinoge

2. Participação de enzimas de reparo por excisão de bases na restauração de lesões induzidas pela associação da radiação ultravioleta A e cloreto estanoso em Escherichia coli / Involvement of base excision repair enzymes in restoring ultraviolet A and stannous chloride induced lesions in Escherichia coli
Stannous chloride (SnCl2) and ultraviolet radiation A (UVA) are able to induce lesions in different cellular structures, including DNA, manly through ROS generation. The aim of this work was to study the mutagenesis and repair of lesions induced by the association of UVA (pre treatment) with SnCl2. It was evaluated the action of base excision repair (BER) en
