...replacing the nitrogen atom with an oxygen atom, researchers found that the new compounds bound specifically to dopamine transporters as well as other transporters in the brain such as serotonin and norepinephrine...
Like all organisms, cells produce waste as they metabolize energy. One of the most troublesome by-products of this process is a species of oxygen molecule known as a free radical--essentially an ordinary molecule with an extra electron. This addition creates an electrical imbalance that the molecule seeks to rectify by careening about, trying to bond with other molecules or structures, including DNA. A lifetime of this can lead to a lot of damaged cells, which may lead to a range of disorders, including cancer and the more generalized symptoms of aging like wrinkles and arthritis...

Unfortunately, as the Farias case makes clear, the dose required to knock...
