“It is hard to know what the mechanism for improved arterial tone is but may be due to functional influences on smooth muscle tone, perhaps linked to reductions in oxidative stress. This study's authors have some conflict of interest, but the pilot study is interesting nonetheless.”

“Cellular damage incurred by oxidative stress underlies the pathophysiology of many chronic health disorders, including neuropsychiatric conditions such as schizophrenia. Glutathione, an antioxidant compound produced by the body’s cells, helps prevent damage from oxidative stress.”

“IGF-1 inhibits the activity of FOXO3, a master regulator of many mammalian genes involved in oxidative stress tolerance and aging. Mice that lack the insulin receptor or the IGF-1 receptor live longer and are more resistant to oxidative stress than normal mice.”

“00:29:20 - Organs shrink during fasting and then regrow after refeeding. Study. 00:29:45 - Fasting stresses healthy cells so they increase their stress-response pathways, including heat shock proteins, antioxidant production, and anti-inflammatory.”

“00:21:41 - The mixed results associated with the use of the ketogenic diet in treatment of cancer and how some cancers seem to be hurt by the metabolic switch of utilizing ketone bodies, which creates oxidative stress from the use of mitochondria, while other cancers seem to be able to use ketones effectively as an energy source, potentially accelerating their growth.”

“Assessments included measures of mitochondrial fuel oxidation, oxidative stress, inflammation, glucose metabolism, body composition, and strength tests, among others. The old adults took a GlyNAC supplement (dose varied according to the participants' bodyweight) every day for 24 weeks; the young adults did not take a GlyNAC supplement.”

“Dr. Patrick connects this mechanism to studies of air-pollutant metabolites and to broader interest in oxidative stress and mitochondrial function. She also reports that her mother, who has essential or orthostatic tremor, seemed to improve after a broccoli-sprout preparation.”

“Repeated, intensive cold exposure can also recruit brown adipose tissue and increase cold-induced thermogenesis. In six men, two hours of daily cooling for four weeks increased active brown-fat volume by 45 percent and more than doubled cold-induced brown-fat oxidative metabolism.”

“Melatonin exerts anti-inflammatory and antioxidative properties that protect against respiratory failure associated with other viral pathogens in animal studies. For example, melatonin ameliorates respiratory syncytial virus‐induced lung inflammatory injury in mice via inhibition of oxidative stress and proinflammatory cytokine production.”

“Graying is generally considered irreversible, but findings from a recent study demonstrate that graying is not necessarily a linear process and may be reversible. One of the primary drivers of graying is oxidative stress, which damages the pigment-producing region of the hair shaft.”
