background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

BACKGROUND AND OBJECTIVES Oxidative stress during abdominal aortic aneurysm (AAA) repair is likely to result as a response to an ischemia-reperfusion injury (IRI) to the lower limbs and gastrointestinal tract. This paper reviews the oxidative stress during AAA repair, with specific reference to biological markers and the potential antioxidant's protective effect. EVIDENCE AND INFORMATION SOUR...

The ocular surface is always attacked by oxidative stress, and cornea epithelial cells are supposed to have their own recovery system against oxidative stress. Therefore we hypothesized that tears supply key molecules for preventing oxidative stress in cornea. The potential target key molecule we focused is selenoprotein P (SeP). SeP is a carrier of selenium, which is an essential trace element...
