nitrous oxide and Aging

nitrous oxide has been researched along with Aging in 61 studies

Nitrous Oxide: Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream.
dinitrogen oxide : A nitrogen oxide consisting of linear unsymmetrical molecules with formula N2O. While it is the most used gaseous anaesthetic in the world, its major commercial use, due to its solubility under pressure in vegetable fats combined with its non-toxicity in low concentrations, is as an aerosol spray propellant and aerating agent for canisters of 'whipped' cream.

Aging: The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.

"Cognitive function was assessed with the Mini Mental State Examination (MMSE) at baseline (the day before surgery) and on the sixth day after surgery, and with modified telephone interview for cognitive status (m-TICS) on the 30th day after surgery.~The introduction of MMSE scale has been explained in the baseline part in the result section.~The Telephone Interview for Cognitive Status-modified scale(m-TICS) is one of the most popular telephone interview-based screening instruments for mild cognitive impairment and dementia. It consists 11 items including wordlist memory, orientation, attention, repetition, conceptual knowledge and nonverbal praxis, which score ranges from 0 to 48, with higher scores indicating better cognitive function" (NCT02267538)
