Ce au descoperit cercet\u0103torii<\/h2>\n

Studiul, publicat \u00een revista GeroScience \u0219i preluat de Science Daily<\/a>, arat\u0103 c\u0103 centenarii prezint\u0103 niveluri neobi\u0219nuite ale unor acizi biliari \u0219i men\u021bin concentra\u021bii ridicate ale anumitor steroizi.<\/p>\n

Aceste caracteristici metabolice difer\u0103 de cele observate la persoanele care \u00eemb\u0103tr\u00e2nesc \u00een mod obi\u0219nuit. Cercet\u0103torii spun c\u0103 ele sunt asociate cu un risc mai redus de deces.<\/p>\n

\u201eStudiul nostru identific\u0103 semn\u0103turi chimice m\u0103surabile \u00een s\u00e2nge, asociate cu o via\u021b\u0103 lung\u0103 \u0219i s\u0103n\u0103toas\u0103. \u00cen\u021belegerea acestor mecanisme ne-ar putea ajuta s\u0103 descoperim procese biologice care protejeaz\u0103 organismul de efectele \u00eemb\u0103tr\u00e2nirii\u201d, a declarat coordonatorul cercet\u0103rii, Stefano Monti.<\/p>\n

Analiza a inclus peste 200 de participan\u021bi<\/h2>\n

Cercet\u0103torii au analizat probe de s\u00e2nge prelevate de la 213 participan\u021bi la New England Centenarian Study, unul dintre cele mai ample proiecte dedicate longevit\u0103\u021bii din America de Nord.<\/p>\n

Lotul a inclus 70 de persoane cu v\u00e2rsta de cel pu\u021bin 100 de ani, copiii acestora \u0219i un grup de control format din persoane de aceea\u0219i v\u00e2rst\u0103.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 au m\u0103surat aproximativ 1.500 de molecule din serul sanguin \u0219i au comparat rezultatele cu alte patru studii similare.<\/p>\n

\u00cen plus, au folosit un model bazat pe inteligen\u021b\u0103 artificial\u0103 pentru a estima v\u00e2rsta biologic\u0103 a participan\u021bilor \u0219i au analizat leg\u0103tura dintre profilul metabolic \u0219i supravie\u021buire.<\/p>\n

Cum ar putea fi folosite rezultatele<\/h2>\n

Autorii studiului spun c\u0103 markerii identifica\u021bi ar putea deveni, \u00een viitor, instrumente pentru estimarea v\u00e2rstei biologice \u0219i pentru identificarea persoanelor cu risc mai mare de boli asociate \u00eemb\u0103tr\u00e2nirii.<\/p>\n

Ei cred c\u0103 ace\u0219ti biomarkeri ar putea fi utiliza\u021bi \u0219i pentru a evalua eficien\u021ba schimb\u0103rilor de stil de via\u021b\u0103 sau a tratamentelor destinate \u00eencetinirii procesului de \u00eemb\u0103tr\u00e2nire.<\/p>\n

Printre mecanismele care vor fi investigate \u00een continuare se num\u0103r\u0103 cele legate de acizii biliari, metabolismul NAD, bacteriile intestinale, stresul oxidativ \u0219i anumi\u021bi steroizi.<\/p>\n

Genele \u0219i stilul de via\u021b\u0103 r\u0103m\u00e2n esen\u021biale<\/h2>\n

Potrivit cercet\u0103torilor, longevitatea excep\u021bional\u0103 este influen\u021bat\u0103 at\u00e2t de mo\u0219tenirea genetic\u0103, c\u00e2t \u0219i de stilul de via\u021b\u0103. Estim\u0103rile arat\u0103 c\u0103 factorii genetici pot explica p\u00e2n\u0103 la jum\u0103tate din capacitatea unei persoane de a ajunge la v\u00e2rste foarte \u00eenaintate.<\/p>\n

\u00cen acela\u0219i timp, o alimenta\u021bie bazat\u0103 \u00een principal pe produse vegetale, activitatea fizic\u0103 regulat\u0103 \u0219i men\u021binerea rela\u021biilor sociale contribuie la o \u00eemb\u0103tr\u00e2nire s\u0103n\u0103toas\u0103.<\/p>\n

Autorii atrag aten\u021bia c\u0103 studiul nu demonstreaz\u0103 o rela\u021bie direct\u0103 de cauzalitate \u00eentre biomarkerii identifica\u021bi \u0219i longevitate. Ei spun c\u0103 rezultatele trebuie confirmate prin cercet\u0103ri mai ample, desf\u0103\u0219urate pe popula\u021bii diverse.<\/p>\n","protected":false},"excerpt":{"rendered":"
