"Our defense against oxidative stress damage may determine at what rate we age, how it will manifest and how to interfere in those processes," Nel said.

Nel说，我们的防御抗氧化重损伤也许将确定什么使我们衰老，它是怎么表达和干预在那些过程。

Dr Lawrence Whalley of the University of Aberdeen, who led the research, said the explanation could be that smoking causes oxidative stress - cumulative damage caused by molecules called "free radicals" - to organs including the brain.

Olive oil is also a rich source of potent antioxidants called polyphenols, which may help slow the progression of atherosclerosis (narrowing of the arteries because of cholesterol and inflammatory cell accumulation) by decreasing the susceptibility of bad cholesterol to oxidative damage and stress.

Moreover, the widespread occurrence of nitrotyrosine in neurons suggests that oxidative damage is not restricted to long-lived polymers such as NFTs, but instead reflects a generalized oxidative stress that is important in disease pathogenesis.
