A free radical is a molecule with an unpaired electron.
Indirect evidence of increased free radical activity (oxidative stress) may be obtained by measurement of antioxidant concentrations in all tissue and body fluids.
And finally a reperfusion injury characterized by free radical formation and oxidative stress.
Thus, desiccation sensitivity may result from an inadequate provision of free radical scavenging mechanisms.
When a free radical reacts with a non-radical molecule a new radical is created, and consequently chain reactions are often initiated.
Free radical scavengers ameliorate the 2-cell block in mouse embryo culture.
The presence of the free radical scavenging enzymes in parasitic organisms has been linked with immunomodulation.
They are known free radical scavengers and metal chelators.
Managing Your Emotions
What makes me angry?
Mostly，l hate when someone tries to make someone else feel bad.
I have to admit that once, when l was actually called names.
l regretted doing this afterwards, but not full heartedly because l think l was provoked in that situation.
The most postive way of dealing with anger is talking about the problem.
l talk to someone who listens, or l'll write my thoughts down on paper.
Learning how to deal with anger as you're growing up is so important.
When you're younger, you might yell,or cry when you're angry, but as you get older, you're expected to handle your emotions much better.
Learning to control your emotion now will prevent you from doing something that you'll regret later on in life!
