Quotes & Sayings About Oxidative Stress

This brings us to the latest area being explored in connection with low-intensity lasers: Alzheimer's disease, the commonest kind of dementia. The Alzheimer's brain is also inflamed, and the mitochondria have difficulty functioning and show signs of aging called oxidative stress, which is a kind of "rusting" of the molecules. Lights, which improve general cellular functioning in the brain, can improve all three conditions - inflammation, mitochondrial problems, and oxidative stress.* The hallmark of Alzheimer's is that the neurons build up excess misshapen proteins, called tau proteins and amyloid proteins, to form plaques that lead to degeneration. — Norman Doidge

For disease prevention, berries of all colors have "emerged as champions," according to the head of the Bioactive Botanical Research Laboratory.39 The purported anticancer properties of berry compounds have been attributed to their apparent ability to counteract, reduce, and repair damage resulting from oxidative stress and inflammation.40 But it wasn't known until recently that berries may also boost your levels of natural killer cells. — Michael Greger

Hypertension is an important risk factor for kidney disease, but dietary sodium has other damaging effects on the kidneys. High salt intake drives the production of oxygen radicals, leading to oxidative stress in kidney tissue. — Joel Fuhrman

Here's how it works. Your immune system protects you from all kinds of nasty bugs and helps repair tissue that has been damaged by injury or surgery. When a problem develops somewhere, your body does the equivalent of calling 911. The alarm sounds, and the immune system springs into action. The first responders, the white blood cells, travel to the site of the problem. As weapons, some of the cells released a shower of powerful free radicals (called an oxidative burst) that aids in the destruction of invading microorganisms and damaged tissue. — Jed Diamond

Activating oxygen can produce compounds called radicals that put oxidative stress on cells. Such stress could ultimately lead to cancer and other diseases. — John Simon

The explanation may be that gene activity in our muscles changes when the muscles don't contract for long periods of time. In one experiment, researchers at the University of Massachusetts asked a group of healthy young men to walk around using crutches such that the muscles in their left legs never contracted. After only two days of inactivity, the scientists biopsied muscles in both legs. In the left leg, the DNA repair mechanism had been disrupted, insulin response was dropping, oxidative stress was rising, and metabolic activity within individual muscle cells was slowing. — Joe Kutner
