“…This can occur due to gene action and/or natural aggressions (Oliveira and Schoffen, 2010). Excessive production of reactive oxygen species (ROS) and nitrogen (RNS) and reduction in the cellular level of antioxidants are among the natural aggressions.…”

“…The high concentration of ROS can cause a condition known as oxidative stress, and the results can be quite harmful to the human body [Oliveira and Schoffen, 2010]. In the present study, older people with higher concentrations of ROS performed worse on tests that evaluated resolution and temporal ordering.…”

This study aimed to assess whether lipid-inflammatory-oxidative metabolism influences auditory processing skills, and whether they function in changing auditory performance after hearing aid fitting in the elderly. Twelve subjects with bilateral hearing loss were submitted to blood tests (to check their lipid-inflammatory-oxidative metabolism) and auditory processing skill tests. After 3 months of using the hearing aids, their auditory skills were re-evaluated and the data were correlated statistically. Oxidative stress levels mainly showed some impact on auditory temporal processing; such a relation and others should best be examined in further studies with larger populations.

“…This slower metabolism and reduction in ROS generation, as well as better protection by the presence of GSH would allow tojustify results of measurements of overall antioxidant protection obtained with oxidation of DCF-DA. A lower level of fluorescence indicates a drop in the pro-oxidant activity within the cells -in both: a better protection effect and a lower internal production of ROS de Oliveira and Schoffen 2010). In this context, it should also be interpreted the results obtained for different types of peroxynitrite treated cells, where the smallest resistance of planktonic cells in log phase weakest correlated with the protection against the effects of exposure to peroxides.…”
