[I have long been fascinated by this ‘accidental waterbody’, from its creation all the way through the extreme pollution issues as it evaporates – and the lithium under it – a heck of a history, culturally, demographically, hydrologically, contaminants, public health, agriculturally and so much more…]

Thiosulfoxide (sulfane) sulfur: new chemistry and new regulatory roles in biology

The conclusion from these findings is that disulfides in the first group generate a growth factor de novo while the compounds in the second group mobilize the growth factor from fetal calf serum. The mechanism common to the first group is the metabolic generation of a carbonyl group adjacent to the disulfide bond resulting in the labilization of one of the sulfur atoms and its release as sulfane sulfur [17] (Table 2). The catalysts effective in the cell cultures were found to be alcohol dehydrogenase for the disulfides of mercaptoethanol and thioglycerol, diamine oxidase for the disulfide of cysteamine (i.e., cystamine), and pyridoxal plus a metal ion or the enzyme cystathionine γ-lyase (γ-cystathionase; CTH), for cystine. Surprisingly, viscose dialysis tubing is also effective [17]; it is manufactured by treating cellulose with carbon disulfide and it contains residual sulfane sulfur chains unless it is exhaustively boiled in water before use. Thiols in the second group at high concentrations (10 mM) were shown to release H2S from fetal calf serum according to Equation (1) [18]:

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 -

@fesshole Rotten eggs, eh? Just inhale even more deeply, preferably ,near an open flame. Sooner or later other people won't be bothered by your appalling halitosis any more. #H2S
