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.
Stress causes the release of a hormone called cortisol. Giving rats daily injections of corticosterone (rat cortisol) for several weeks kills certain brain cells. Stressing the rats each day for the same amount of time has an identical effect. Cortisol has been shown to damage and kill cells in the hippocampus (the brain area responsible for your episodic memory) and there is robust evidence that chronic stress causes premature brain aging.
