6) Desafios relacionados à avaliação do estresse oxidativo no processo de envelhecer.

Oxidative stress is defined as a pathophysiological condition in which the production of reactive species exceeds the ability of the body's antioxidant defenses to remove them. Assessing the degree of oxidative stress is essential for understanding the various physiological processes that maintain homostasy in the various phases of the life cycle. For this, several simple and inexpensive techniques can be employed. The present work proposes to present some techniques to study the study of oxidative stress, reflecting on its potentialities and limitations. It can be said that the credibility of the study is elevated by the careful standardization of the techniques, rigor of the experimental design and the confirmation of the results through different techniques that evaluate different processes that determine the redox balance.
