“The authors of the retrospective case-control investigation reviewed imaging reports from more than 52,000 adults who had undergone diagnostic positron emission tomography (PET) scans (nearly 135,000 total scans). They also reviewed the participants' health records.”

“It is present in fine inhalable particles, with diameters that are generally 2.5 micrograms or less. Exposure to air pollution promotes oxidative stress and increases the risk of developing many chronic diseases, including cardiovascular disease, cancer, hypertension, and diabetes.”

“NF-kB influences several aspects of the body’s stress response via its participation in signaling pathways that drive pro-inflammatory processes, ultimately regulating DNA transcription, cytokine production, cell survival, and immune function.”

“Nrf2 is a protein typically found in the cytoplasm of mammalian cells. Nrf2 can relocate to the nucleus, where it regulates the expression of hundreds of antioxidant and stress response proteins that protect against oxidative damage triggered by injury and inflammation.”

“Helping behavior has also been linked to changes in stress regulation systems and immune functioning. Although the study cannot prove cause and effect, its focus on within-person changes, timing, and dose strengthens the case that helping itself could contribute to better cognitive aging.”

“For example, a comprehensive review of the effects of microplastics revealed that the pollutants induce oxidative stress and increase the risk for metabolic dysfunction, neurotoxicity, and some cancers.”

“Those who practiced intermittent fasting also experienced reductions in blood pressure, insulin resistance, oxidative stress, LDL, and triglycerides. Weaker evidence indicated that intermittent fasting improved appetite regulation and gut microbial diversity.”

“If not eliminated by immune cells, shear stress (frictional force in blood vessels), or other protective mechanisms, CTCs can spread to other body parts, driving metastasis.,, Surviving CTCs can be detected and isolated using antibodies that interact with molecules expressed on tumor cell surfaces, but ideally not on healthy cells.”

“Light acts as the primary zeitgeber, but activity, stress, and eating also affect circadian timing. Exercise affects body temperature, heart rate, and many other metabolic parameters and might also entrain the circadian clock.”

“Heat stress, such as that experienced during sauna use, robustly induces expression of heat shock proteins. Learn more about heat shock proteins and sauna use in our overview article. View full publication.”
