Exercise training modulates heat shock protein response in diabetic rats.
Examination of the effect of 8 wk of endurance training on HSP expression and oxidative stress markers in the skeletal muscle, heart, and liver of streptozotocin-induced diabetic and nondiabetic control rats suggests that diabetes impairs HSP protection.
Antioxidant responses to simulated acid rain and heavy metal deposition in birch seedlings.
Skeletal muscle and liver glutathione homeostasis in response to training, exercise, and immobilization.
Endurance training elevated the antioxidant and detoxicant status of muscle and liver, respectively, and total glutathione decreased in the trained leg muscles.
Exercise-induced oxidative stress: glutathione supplementation and deficiency.
GSH-deficient rats had approximately 50% reduced endurance, which suggests a critical role of endogenous GSH in the circumvention of exercise-induced oxidative stress and as a determinant of exercise performance.

Despite higher levels of hepatic lipid peroxidation at rest in FOVE compared with SOVE, liver appeared to be relatively less susceptible to exercise-induced oxidative stress in FOve.
Incorporation of n-3 fatty acids into plasma lipid fractions, and erythrocyte membranes and platelets during dietary supplementation with fish, fish oil, and docosahexaenoic acid-rich oil among…
Results suggest retroconversion of DHA to EPA and that DHA also interferes with linoleic acid metabolism and that N-3 fatty acids increased and those of n-6 fatty acids decreased significantly in plasma lipid fractions and in platelets and erythrocyte membranes.
Lactobacillus strain GG supplementation decreases colonic hydrolytic and reductive enzyme activities in healthy female adults.

Data demonstrate that L. GG can modify the colonic environment with possible health effects, and yogurt alone or with fiber significantly decreased fecal beta-glucuronidase, nitroreductase and glycocholic acid hydrolase activities.
Fish diet, fish oil and docosahexaenoic acid rich oil lower fasting and postprandial plasma lipid levels.
It is shown that both fasting and postprandial triglyceride concentrations can be decreased with moderate intakes of long-chain n-3 fatty acids either from a fish diet or fish oil and that also pure DHA has a hypotriglyceridemic effect.

The results suggest that endurance horses have higher oxidative stress levels compared to trotters and a single 80-km ride probably did not suffice to induce oxidative stress and to activate antioxidant defense mechanisms.
