Biological aging clocks use DNA methylation patterns and other biomarkers to estimate different dimensions of biological aging, including how old the body appears at the molecular level, how quickly aging-related changes are accumulating, and whether lifestyle or medical interventions may be changing the trajectory of aging.

“DAMPs such as HMG-1 bind to TLR4 and receptors for advanced glycation end products (RAGE) on cells at the blood-brain barrier to induce an immune response that initially inhibits the deposition of amyloid-beta, a key feature of Alzheimer's disease progression.”

“However, findings from a rodent study indicate that even low levels of nicotine exposure during pregnancy or early in life can increase the risk of sudden infant death syndrome, or SIDS, by inhibiting the neonate's ability to autoresuscitate – the capacity to recover from prolonged periods of apnea, widely considered a causal factor in SIDS.”

“Researchers evaluated the effects of these changes in a study involving 37 men and women who practiced voluntary long-term caloric restriction (approximately 30 percent of habitual intake) for 3 to 15 years, compared to sedentary and fit people eating a traditional Western diet.”

“In a randomized crossover study, eight trained men completed four days of daily cycling while eating either a low-carbohydrate, high-fat diet (12 percent carbohydrate) or a normal-carbohydrate diet (62 percent carbohydrate).”

“The study involved 112 women between the ages of 39 and 59 years who were assigned to take a placebo (500 milligrams of cellulose) or a commercial product (containing 300 milligrams of hydrolyzed type II collagen, 100 milligrams of chondroitin sulfate, and 50 milligrams of hyaluronic acid) twice a day for 12 weeks.”

“Creatine improves vascular health To investigate creatine's effects on blood vessel health—specifically by measuring the ability of arteries and small blood vessels to increase in size to accommodate blood flow (known as endothelial function)—one study recruited 12 healthy men and women with an average age of 59 and supplemented them with creatine or a placebo for 28 days each.”

“Neurogenesis Whereas the early view of the mammalian central nervous system presumed that it was a static complex incapable of change, a growing body of evidence suggests that it retains its capacity for synaptic pruning – the process that eliminates extra neurons and synaptic connections and establishes new neural circuits to increase the efficiency of neuronal transmissions – throughout life.”

“In laboratory tests, the redesigned factors produced more than 50-fold higher expression of stem-cell reprogramming markers than wild-type controls and generated stable induced pluripotent stem cell lines across multiple donors and delivery methods.”

“When we engage in high-intensity exercise, our muscles become mini biochemical laboratories, synthesizing compounds like lactate and myokines that circulate throughout the body and travel to our organs, where they exert a variety of signaling effects, including the synthesis of brain-derived neurotrophic factor (BDNF) in the brain.”
