ukuhamba ngokukhawuleza ukulibazisa ukwaluphala

Uphando luqhubeka lubonisa iindlela apho indlela yokuphila esebenzayo inokuchasana nemiphumo ethile yokuguga, kubandakanywa ukuqala komonakalo wentliziyo, ukulahleka kwememori kunye nokuphazamiseka kwengqondo.

Uphononongo olutsha lufumene ubudlelwane phakathi kwesantya sokuhamba kunye nobudala bebhayoloji. Uphononongo lusebenzise isethi enkulu yedatha yemfuza ukubonisa ukuba abo bahamba ngokukhawuleza banokuhlala besempilweni ixesha elide, i-New Atlas ibika, ikhankanya i-Biology yoNxibelelwano.

Ukuhamba kunye nokuphila ixesha elide

Ngo-2019, abaphandi bajonge kuphononongo olunomdla olujonga amakhonkco phakathi kwesantya sokuhamba kunye nempilo, ebonisa ukuba ukuhamba kancinci kancinci kwi-10s yakho kuhambelana nezalathisi zebhayoloji zokuguga okukhawulezileyo, ezinjengokuncitshiswa komthamo wobuchopho ngokubanzi. Ngokufanayo, abaphandi kwiYunivesithi yaseLeicester baye babonisa ngaphambili ukuba imizuzu nje ye-XNUMX yokuhamba ngokukhawuleza ngosuku kunokunyusa ubude bobomi bomntu ukuya kuthi ga kwiminyaka emithathu.

Kuphononongo olutsha, abaphandi basebenzise idatha yemfuza ukuze baqinisekise into abayithethayo ikhonkco le-causal, kunye nomphandi okhokelayo uTom Yates wathi: "Nangona siye sabonisa ngaphambili ukuba isantya sokuhamba sisingqinisiso esinamandla kakhulu sempilo, asikwazanga qinisekisa ukuba ukuthatha isantya sokuhamba ngokukhawuleza kukhokelela kwimpilo eNgcono .. Kolu phononongo sisebenzise ulwazi oluvela kwiprofayili yemfuza yabantu ukubonisa ukuba isantya sokuhamba sikhokelela kubomi obuncinci bebhayoloji njengoko kulinganiswe ngeetelomeres, izigqubuthelo ezisekupheleni kweechromosomes. zikhusele emonakalweni, yiyo loo nto zijolisa ingqalelo.” Uphando oluninzi ngemiphumo yokwaluphala.

"Xa iiseli zethu zihlukana, i-telomeres iyancipha kwaye ekugqibeleni inqande iseli ukuba ihlukane ngakumbi, iguqule ibe yinto eyaziwa ngokuba yiseli ye-senescent," uYates wongezelela. Yiyo loo nto ubude be-telomere sisiphawuli esiluncedo sokulinganisa iminyaka yebhayoloji.

iminyaka encinci yebhayoloji

Uphononongo olutsha luhlalutye idatha yofuzo evela kwi-UK Biobank kwi-400 yabantu abadala abaneminyaka ephakathi kwaye yathelekisa nolwazi malunga nezantya zokuhamba ezixeliweyo ukusuka kwi-trackers yomsebenzi enxitywe ngabathathi-nxaxheba, njengenxalenye yezifundo zokuqala ezithathwe kunye, ezi zinto. zifundwa, ziseka ikhonkco elicacileyo phakathi kokuhamba ngokukhawuleza kunye nobudala obuncinci bebhayoloji.

Ukuxela kwangaphambili ukuvezwa kwezifo ezingapheliyo

Kwiphepha labo, izazinzulu zibhale ukuba umahluko phakathi kwabo bachazwa njengabahamba ngokukhawuleza kwaye bacotha yayingumahluko weminyaka eyi-16, kuxhomekeke kubude be-telomere. indima ebalulekileyo ekwenzeni ungenelelo [ukuphucula impilo].
