Repositório Institucional UFC: Generalized anxiety disorder (GAD) and comorbid major depression with GAD are characterized by enhanced nitro-oxidative stress, increased lipid peroxidation, and lowered lipid-associated antioxidant defenses
... Another finding is that the nitro-oxidative pathways mea- sured here are modulated by sex, nicotine dependence, and years of education. Thus, males show higher LOOH, AOPP, and uric acid levels, but lower catalase and ...

Swimming training attenuates oxidative damage and increases enzymatic but not non-enzymatic antioxidant defenses in the rat brain
... The brain is believed to be particularly vulnerable to oxidative stress because it contains high concentrations of polyunsaturated fatty acids (which are more susceptible to lipid peroxidation), consumes relatively large ...

Diabetic beta-cells can achieve self-protection against oxidative stress through an adaptive up-regulation of their antioxidant defenses.
... As previously mentioned, after diabetes onset in GK/Par rats, b-cells are exposed in vivo to chronic inflammation and therefore to a complex combination of ROS/NO/cytokines [51,52], first at the islet periphery before ...
