Plasma non-transferrin bound iron (NTBI) is potentially toxic and contributes to the generation of reactive oxygen species (ROS), consequently leading to tissue damage and organ dysfunction. Iron chelators and antioxidants are used for treatment of thalassemia patients. Green tea (GT) contains catechins derivatives that have many biological activities.

Excessive iron catalyzes free-radical formation, causing oxidative tissue damage. Non-transferrin bound iron (NTBI) detected in thalassemic plasma is highly toxic and chelatable.

Excessive iron catalyzes free-radical generation, leading to oxidative damage and vital organ dysfunction. Non-transferrin-bound iron (NTBI) detected in thalassemic plasma is highly toxic and chelatable.

Previous studies revealed that MSI-H cancers are more likely to occur in women, irrespective of the higher incidence of colorectal cancer in men. In this study we investigated the gender-specific clinico-pathological features of MSI positive colorectal cancer in Japanese individuals.

Likewise, the uptake of glutamic acid, leucine and arginine was diminished.
