Thank you for your well-reasoned and detailed response. You are clearly more skilled at interpreting this article than I am. I share your concern that we could not find a published version of this 2019 preprint. Was it ever submitted for publication? Was it rejected? I don’t know.
I wasn’t able to find out if it was ever published beyond the pre-print status. I found a bunch of references but all to the same paper you and i saw.
The question is what is “elderly”? Are you sure you are “elderly”, you definitely don’t look like one.
I wondered this as well @LaraPo. When you dig into the claim it seems a possibility that the researchers have conflated age, say 70 or older, with physical condition, such as frailty, sarcopenia, etc. I would like to see a study stratified not by age but some of the standard fitness metrics.
Metformin protects against vascular calcification. The metformin dosage used in the current study (1 mM) and inadditional in vitro experiments (0.5 mM) (Cao et al.,2013;Qiuet al.,2021) can be correlated to the high dosage of metformin(>1700 mg/day) used in human clinical trials. Interestingly, only this highdosage was able to reduce triglyceride levels and high‐densitylipoprotein function, which may contribute to the anti‐atheroscleroticeffect (Luo et al.,2019). F
The picture is flattering and was just a lucky shot selected from several that weren’t as flattering. But I do believe based on what I see at my doctor’s office and what I am told, I do look younger than most 83-year-olds. When I look in the mirror I see an old man even though I don’t feel that way inside.
Dr. Mercola had a article on the fatality of Rapamycin in diabetics. It has to do with the ATP Cycle.
