Unopposed free radicals can damage sensitive cells in the brain, the gastrointestinal tract, and the immune system, and the researchers believe they may contribute to the neurological, gastrointestinal and immunologic pathology that occurs in autistic children.

For example, mutant or overexpressed a synuclein causes intracellular inclusions (Lewy bodies) and cell degeneration of dopamine neurons. Such mechanisms are considered central to t...... broken ends back together again. With the help of sensitive measuring devices, the researchers could measure various parameters such as the friction of the rotating DNA in a cavity of the enzyme.
