Superoxide Dismutase (SOD) – The Good – Superoxide – The Bad – Disease – The Ugly

We can’t live without oxygen. Our cells rely on oxygen as the final acceptor of electrons in respiration, allowing us to extract far more energy from food than would be possible without oxygen. But oxygen is also a dangerous compound. Reactive forms of oxygen, such as superoxide (oxygen with an extra electron), leak from the respiratory enzymes and wreak havoc on the cell. This superoxide can then cause mutations in DNA or attack enzymes that make amino acids and other essential molecules. This is a significant problem: Continue reading

Hyperbaric Oxygen In Cancer Treatment

It has been long known in the medical field that that proper healing of the body and resistance to infection cannot occur without oxygen. Oxygen is believed to be required for all the major processes involved in wound healing, including resistance to infection, activation of fibroblasts, collagen deposition, angiogenesis, and epithelization. Under normal circumstances, oxygen is carried through the body by red blood cells only, this is sufficient for a healthy person to have all the oxygen required to maintain normal functioning. But what about when someone is sick and how does this play a role in cancer treatment? Continue reading

Free Radicals in the Body – Oxidative Stress and the Antioxidant Response

The basic science of oxidative stress and the antioxidant response is not in contention, what is an effective antioxidant is. When the body breaks food down into energy, it generates a by-product known as free radicals. Also present in food itself, the air we breathe and the sun we worship, free radicals are a broad class of chemicals with the potential to exert significant damage. By ‘stealing’ electrons from nearby molecules, free radicals in the body may tamper with DNA and impede normal cell function. Continue reading
