Good Signs ke pheko ea phetoho e khahlanong le botsofali

Le hoja botsofali e ntse e le karolo e ke keng ea qojoa ea bophelo, bo-rasaense ba ntse ba atamela ho nts'etsopele ea mekhoa ea phekolo e ka thusang ho ntlafatsa phihlelo le ho fokotsa liphello tsa eona tse mpe, ka mor'a hore liphuputso tse fetileng li bontšitse hore molek'hule ea hydrogen sulfide donor AP39 e tsosolosa bophelo bo botle ba lisele tse tsofetseng. Univesithi ea Exeter e bile le liphello tse ling tse tšepisang ho tsoa litekong tsa tsona tsa liphoofolo, ho latela New Atlas, e qotsa Proceedings of the National Academy of Sciences.

Mitochondria ka har'a lisele

Ka ho lebisa mitochondria ka har'a lisele tsa mofuta oa Caenorhabditis elegans, phekolo ea H2S e atlehile ho khothalletsa lisele tsa botsofali tse phetseng hantle le ho boloka mesifa e sebetsa le ho ba boemong bo botle ha ba ntse ba tsofala.

Hydrogen sulfide

"Liboko ke sesebelisoa se matla sa liphatsa tsa lefutso bakeng sa ho ithuta bophelo bo botle ba batho le maloetse 'me se fana ka sethala se matla sa ho tseba ka potlako mekhoa e mecha ea phekolo," ho boletse Tim Etheridge, mofuputsi e moholo le moprofesa Univesithing ea Exeter, a phaella ka hore "mafu a amanang le botsofali a nka matla a maholo. tefiso sechabeng. Liphuputso tsa rōna li bontša hore hydrogen sulfide, e kenngoang likarolong tse itseng tsa sele ka tekanyo e nyenyane, ka letsatsi le leng e ka sebelisoa ho thusa batho ho phela bophelo bo botle ka nako e telele.” Katleho ea bafuputsi e ile ea thusa ho lemoha ka lekhetlo la pele a mang a mabaka a bohlokoa a ho ngoloa. Molek'hule ea bafani ba hydrogen sulfide AP39, e nang le bokhoni ba ho thibela maloetse le ho boloka bophelo bo ntlafetseng lilemong tse tlang.

"Phuputso ha e mabapi le ho phela nako e telele - e mabapi le ho phela bophelo bo botle ho fihlela botsofaling," ho boletse sengoli-'moho Matt Whitman, moprofesa Univesithing ea Exeter, a hlokomela hore liphumano tsa eona li ka ba le melemo e meholo sechabeng, mme a hlalosa. sehlopha sa thabo ea bafuputsi “ho bona sena Patlisiso e fetela mehatong e latelang lilemong tse tlang, tseo ka letsatsi le leng e ka bang motheo oa liphekolo tse ncha.”

Le hoja melemo e meng ea bophelo e ile ea bonoa libokong tse tšoaroang ka H2S, bafuputsi ba re mofuta ona oa phekolo o tla thusa ho tsepamisa maikutlo ho tsofalang ho phela hantle le ho boloka boleng ba bophelo.
