The urinary oxidative protein damage in cancer is significantly higher than diabetes mellitus (with and without hypertension) and may potentially serve as a non-invasive oxidative biomarker for cancer.

Beta-thalassaemia major patients require monthly blood transfusions. Studies on the oxidant-antioxidant indices in patients on desferrioxamine-chelation or without chelation indicate that desferrioxamine chelation does not normalize ferritin level but attenuates oxidative damage and improves total antioxidant level in these patients.

This study investigated the effects of acute exposure to alcohol on gastric mucosa and the possible ameliorating role of Carica papaya leaf aqueous extract on blood oxidative stress indices. The extract conferred some protection against acute gastric and oxidative damage.
