Oxidative stress is less harmful than first thought
Tuesday 6th December 2011
Oxidative stress, which is blamed for conditions such as coronary heart disease, Parkinson's and Alzheimer's by doctors and cardiac physiologists, is less than harmful than first thought.
A new study carried out at the German Cancer Research Centre (DKFZ) has for the first time been able to observe oxidative changes in a living organism.
Tobias Dick, a researcher at the DKFZ, tested the substance on fruit flies and found that the ageing process within the insects was not directly affected by the oxidative.
Mr Dick said: "Many things we observed in the flies with the help of the biosensors came as a surprise to us. It seems that many findings obtained in isolated cells cannot simply be transferred to the situation in a living organism. Our next goal is to use the biosensors to observe oxidative processes in mammals, especially in inflammatory reactions and in the development of tumours."
It is hoped that this new finding can help fight diseases like Parkinson's, which in the UK alone one person is told they have each hour.
