(Adnkronos) - "Sima", a 47 months-old female rat, is being treated with E5, a treatment intended to recreate the circulatory environment of a young mammal; the maximum recorded lifespan for this species is 45.5 months.
MOUNTAIN VIEW, Calif., Feb. 8, 2023 /PRNewswire/ -- An experiment led by Dr. Harold Katcher, one of the
This experiment is a follow-up to another experiment showing that Yuvan's therapy caused a 54% rejuvenation in male rats according to an epigenetic clock analysis performed by then UCLA professor Dr. Steve Horvath. Afterward, a Belgian non-profit, HEALES, decided to fund two lifespan studies, one using Yuvan's treatment, called "E5", and another one, led by Dr. Rodolfo Goya, professor at La Plata University (Argentina), using young rat plasma. Dr. Goya's experiment achieved moderate life extension. Yuvan's experiment is still ongoing as Sima is alive at 47 months of age.
Also, Sima and the other treated rats showed a grip strength 2.8 times higher than the controls. According to Dr. Goya, "muscular strength indicates prolonged healthspan." Sima is a Rattus norvegicus, a species with a maximum recorded lifespan of 45.5 months. Their average lifespan is 24-36 months. Yuvan's treatment started when the rats were already 24 months old and even so pushed the maximum lifespan of the species with a treated group comprising only 8 rats.
The E5 production process is patent-pending, and the story of its discovery is captured in Dr. Katcher's book The Illusion of Knowledge. Yuvan is planning trials in other species before testing it in humans — in human terms, Sima is already 126 years old, considering 122.5 years as the human maximum lifespan. "Sima" means "limit/boundary/frontier" in Sanskrit, and by surpassing the lifespan limit of its species, it reminds us that human history is a history of surpassing limits.
