ObjectivesTo summarize information on anti-aging substances and nanotechnology formulations against aging and to unveil emerging anti-aging approaches like gene therapy, stem cells, monoclonal antibodies, and future trends. MethodsA systematic literature search was conducted through May 10, 2021. Eligibility criteria were articles in English relevant to the aim of this review. ResultsAnti-aging substances like coenzyme Q10, curcumin, ginsenoside Rg1, bioidentical hormones, and geroprotectants, can help to slow the aging process. Nano-delivery of anti-aging substances are novel approaches able to delay aging. Cryogenic sleep, therapeutic hypothermia, and caloric restriction are promising interventions that may one day grant humans biological immortality. DiscussionThe ability to target basic maturation mechanisms, such as responses to oxidative damage, inflammation, irritation, and senescence associated with multiple concurrent deficits, is the most important feature. Nanocarriers to transport bioactive compounds have been shown to improve their stability, increase intestinal absorption, and prolong their circulation time.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
