\nCum compara\u0163i v\u00e2rsta unui c\u00e2ine cu cea a unei persoane? O metod\u0103 popular\u0103 spune c\u0103 ar trebui s\u0103 \u00eenmul\u0163i\u0163i v\u00e2rsta c\u00e2inelui cu 7 ani pentru a calcula v\u00e2rsta animalului de companie \u00een \u201eani umani\u201d.<\/p>\n
\n\u00cens\u0103 o nou\u0103 cercetare publicat\u0103 \u00een revista Cell Systems demonteaz\u0103 aceast\u0103 metod\u0103. \u015ei asta pentru c\u0103 oamenii de \u015ftiin\u0163\u0103 din spatele unui nou studiu spun c\u0103 oamenii \u015fi c\u00e2inii nu \u00eemb\u0103tr\u00e2nesc \u00een acela\u015fi ritm, scriu cei de la CNN.<\/p>\n
\nCercet\u0103torii de la Universitatea din California San Diego School of Medicine au dezvoltat o nou\u0103 formul\u0103 care \u0163ine cont de aceast\u0103 variant\u0103. Urm\u0103rirea modific\u0103rilor moleculare \u00een ADN-ul c\u00e2inilor din rasa Labrador, \u00een special \u201eschimbarea tiparelor grup\u0103rilor metilice\u201d din genomul lor, arat\u0103 modul \u00een care c\u00e2inii \u00eemb\u0103tr\u00e2nesc cu o vitez\u0103 mult mai rapid\u0103 dec\u00e2t oamenii la \u00eenceputul vie\u0163ii, apoi ritmul \u00eemb\u0103tr\u00e2nirii \u00eencetine\u015fte dup\u0103 atingerea maturit\u0103\u0163ii.<\/p>\n
\n\u201eAcest lucru are sens atunci c\u00e2nd te g\u00e2nde\u015fti c\u0103, la urma urmei, un c\u00e2ine \u00een v\u00e2rst\u0103 de nou\u0103 luni poate avea pui, a\u015fa c\u0103 \u015ftiam deja c\u0103 raportul 1: 7 nu era o m\u0103sur\u0103 exact\u0103 a v\u00e2rstei”, spune Trey Ideker, autorul principal al studiului.<\/p>\n
\nPe baza studiului, un c\u00e2ine \u00een v\u00e2rst\u0103 de un an se compar\u0103 cu un om \u00een v\u00e2rst\u0103 de 30 de ani, un c\u00e2ine \u00een v\u00e2rst\u0103 de patru ani cu un om \u00een v\u00e2rst\u0103 de 52 de ani. Rata \u00eemb\u0103tr\u00e2nirii scade dup\u0103 ce c\u00e2inii \u00eemplinesc 7 ani.<\/p>\n
\nNoua formul\u0103 \u201eeste prima care este transferabil\u0103 \u00eentre specii\u201d, iar oamenii de \u015ftiin\u0163\u0103 inten\u0163ioneaz\u0103 s\u0103 \u00ee\u015fi testeze constat\u0103rile asupra altor rase de c\u00e2ini pentru a studia impactul longevit\u0103\u0163ii asupra descoperirilor lor, potrivit unui comunicat.<\/p>\n
\nDe asemenea, cercet\u0103torii consider\u0103 c\u0103 respectarea schimb\u0103rilor \u00een modelele de metilare \u00eenainte \u015fi dup\u0103 utilizarea produselor anti-\u00eemb\u0103tr\u00e2nire ar putea ajuta medicii veterinari s\u0103 ia decizii mai informate \u00een ceea ce prive\u015fte diagnosticul \u015fi tratamentul.<\/p>\n
\nUn grafic din studiu face compararea v\u00e2rstei intuitiv\u0103 \u015fi ofer\u0103 un context util pentru proprietarii de c\u00e2ini, inclusiv pentru oamenii de \u015ftiin\u0163\u0103 \u00een\u015fi\u015fi.
\n\u201eAm un c\u00e2ine \u00een v\u00e2rst\u0103 de \u015fase ani – \u00eenc\u0103 mai alearg\u0103 cu mine, dar acum \u00eemi dau seama c\u0103 nu este at\u00e2t de \u201et\u00e2n\u0103r\u201dcum credeam c\u0103 este\u201d, a spus Ideker.<\/p>\n","protected":false},"excerpt":{"rendered":"
