“A liver cell and a neuron contain essentially the same DNA, but they behave differently because different genes are active or silent. DNA methylation helps regulate that cellular identity. With aging, methylation marks can be gained or lost in the wrong places.”

“The improvements in learning were attributed to increased levels of brain-derived neurotrophic factor (BDNF) in the mothers' milk. BDNF is a type of neurotrophin – or growth factor – that controls and promotes the growth of new neurons.”

“In a study involving diet-induced diabetic mice, injection of 500 milligrams per kilogram of body weight (mg/kg/bw) of nicotinamide mononucleotide administered for seven days enhanced insulin sensitivity and improved glucose intolerance compared to that observed among mice not given nicotinamide mononucleotide.”

“Neurodegenerative disease Failures in mitophagy are strongly implicated in Parkinson's disease, a neurodegenerative disorder characterized by mitochondrial dysfunction and energy deficits in dopaminergic neurons in the brain.”

“Resveratrol: Resveratrol is a polyphenol found in red wine, among other plant sources, and is known for its antioxidant and anti-inflammatory properties. It has been studied for its ability to protect neurons by neutralizing free radicals, reducing inflammation, and enhancing neuronal energy metabolism.”

“They found that Hsp70 suppressed the toxicity of amyloid-beta in cells of the flies' eyes, reduced cell death in brain neurons, and helped maintain the neurons' architecture and function.”

“This form of DHA is only transported through the Mfsd2a transporter and is required for growth of new membranes in neurons and other cell types during the time when the brain is rapidly growing.”

“Events experienced during periods of wakefulness trigger the activity of different neurons in the brain. During sleep, the brain "relives" those events by triggering the activity of the same neurons – at 10 to 20 times the original speed.”

“Using isotope tracers that allowed them to distinguish NAD+ made directly from NR or NMN versus NAD made from nicotinamide, NR, or NMN, they found that a low oral dose of the precursors (50 milligrams per kilogram body weight, mg/kg/bw) produced very low levels of NAD+ made directly from NR and NMN in the liver but not in other tissues.”

Photobiomodulation is a non-invasive, light-based therapeutic technique that stimulates biological processes within cells and tissues, with potential applications in medicine, dentistry, cosmetic procedures, and scientific research.
