#NaturalGas is composed mostly of #climate-warming #methane but also contains other gases such as #HydrogenSulfide, which is #deadly at high concentrations. #Gas escapes as wells are drilled & before infrastructure is in place to capture it. It also can be intentionally released if pressure in the system poses a safety risk or if capturing & transporting it to be sold is not profitable.

The reason I'm wondering about hydrogen sulfide is because it induces torpor.
I did some searching and found a study suggesting similarities between H2S and donepezil -

"Exogenous H2S up-regulates the expression of ADAM10 and ADAM17 and sAPPα, and effectively reduce the production of Aβ40, Aβ42 and sAPPβ in vitro in PC12. The PI3-K or JNK signal pathway may be involved in the regulation. Donepezil has similar effects as H2S, which involves PI3-K, JNK or p38 MAPK signaling."

So now I'm wondering why donepezil isn't disease modifying in Alzheimer's. However, I found this -

Donepezil delays progression to AD in MCI subjects with depressive symptoms
