\n\u00cen 2019, speran\u0163a de via\u0163\u0103 a fetelor n\u0103scute \u00een Europa era de 84 de ani, comparativ cu 78,5 ani pentru b\u0103ie\u0163i. Acest fenomen nu este limitat la Europa, fiind comun \u00een majoritatea \u0163\u0103rilor lumii.<\/p>\n
\nCercet\u0103torii de la Universitatea Osaka au studiat pe\u015ftele turquoise killifish, o specie de ap\u0103 dulce care tr\u0103ie\u015fte doar c\u00e2teva luni \u015fi care prezint\u0103 un proces de \u00eemb\u0103tr\u00e2nire asem\u0103n\u0103tor cu cel al oamenilor. Aceast\u0103 specie a fost aleas\u0103 deoarece diferen\u0163ele de speran\u0163\u0103 de via\u0163\u0103 \u00eentre masculi \u015fi femele sunt evidente \u015fi u\u015for de observat.<\/p>\n
\nStudiul a ar\u0103tat c\u0103 celulele germinale (ovulele la femele \u015fi spermatozoizii la masculi) ar putea influen\u0163a durata de via\u0163\u0103. Cercet\u0103torii au observat c\u0103 atunci c\u00e2nd aceste celule au fost \u00eendep\u0103rtate de la pe\u015fti, diferen\u0163ele de speran\u0163\u0103 de via\u0163\u0103 dintre masculi \u015fi femele au disp\u0103rut.<\/p>\n
\nSc\u0103derea produc\u0163iei de estrogen la femele a fost asociat\u0103 cu o speran\u0163\u0103 de via\u0163\u0103 mai mic\u0103 \u015fi un risc crescut de boli cardiovasculare. La masculi, produc\u0163ia crescut\u0103 de vitamina D a fost asociat\u0103 cu o \u00eembun\u0103t\u0103\u0163ire a s\u0103n\u0103t\u0103\u0163ii \u015fi o via\u0163\u0103 mai lung\u0103.<\/p>\n
\nPentru a testa rolul vitaminei D, cercet\u0103torii au administrat un supliment de vitamina D pe\u015ftilor masculi \u015fi femele. Rezultatele au confirmat c\u0103 suplimentarea cu vitamina D a prelungit durata de via\u0163\u0103 a pe\u015ftilor.<\/p>\n
\nStudiul publicat \u00een Science Advances sugereaz\u0103 c\u0103 celulele germinale \u015fi hormonii joac\u0103 un rol important \u00een diferen\u0163ele de speran\u0163\u0103 de via\u0163\u0103 \u00eentre sexe. Descoperirile ar putea deschide calea pentru noi cercet\u0103ri asupra leg\u0103turii dintre vitamina D \u015fi longevitate la oameni.<\/p>\n","protected":false},"excerpt":{"rendered":"
Un nou studiu realizat de cercet\u0103torii japonezi ar putea explica de ce femeile tr\u0103iesc, \u00een medie, mai mult dec\u00e2t b\u0103rba\u0163ii.
