IOException Example in Java. In this tutorial I am going to explain one of the most common Java exception that is well known by all the Java developers. IOExceptions are thrown when there is any input / output file operation issues while application performing certain tasks accessing the files.
Understanding Oxidative Stress. Like an apple turns brown when exposed to air, our cells can ârustâ when we breathe due to oxidative stress, a process caused by free radicals. Free radicals are unstable molecules that damage or âoxidizeâ cells throughout the body in a process called oxidative stress.
Oxidative stress has been deï¬ned as harm-. ful because oxygen free radicals attack biological molecules such as lipids, pro-. teins, and DNA. However, oxidative stress also has a useful role in physiologic. adaptation and in the regulation of intracellular signal transduction.
