Abantwana balala kancinane, akhule ngokukhawuleza kwinqanaba yeselula

Abantwana abancinane badla nzima ukuba ukulala, kodwa ngenene uyifuna bona. Ngaphandle ubuthongo ubuthi azinikezelwanga zisuswe ingqondo, memory elifutshane elide angabuyi ibe ixesha elide, amandla okucinga yokuqonda nokusombulula iingxaki kuyathotywa, kwaye ingqondo iqala ukutshabalalisa ngokwayo.

Njengoko isifundo esitsha, ogama iziphumo zapapashwa kulindixesha "iPediatrics", iphupha - iphinde ibe yindlela elungileyo ukwandisa ubomi bakho. Ngokukodwa, nokungalali ebuntwaneni ebangela ukwehla ngokukhawuleza kwiphondo DNA.

Ukususela oko kuxhomekeke izinga lokuguga yeselula?

Izifundo ziye ngaphambili enxulumene ukungalali ngomyinge ukwanda wokwaluphala yeselula. Le rate kudla kumiselwa ngurhulumente telomere - kwiindawo ezithe shinyi zofuzo zethu.

Telomere (ukusuka yesiGrike. "Iinxalenye Isiphelo") ukuthintela ezo ngempazamo zofuzo angabamelwane kunye nomonakalo yazo yendalo.

Senescence ikhokelela ucinezelo ezi telomers, apho zofuzo kuhlala ungakhuselekanga kwaye lula. Le mihlathana telomere, indoda endala.

Ukongeza, telomere ezimfutshane kwandisa wayevuma ukuba isifo sentliziyo, uphuhliso zizigulo zemithambo, iingxaki zengqondo, kwaye umhlaza.

olwenziwa eMelika

Iqela izazinzulu University yasePrinceton isigqibo ukufumana ukuba ingaba le ndlela iye yabonakala ebantwaneni, hayi nje kuphela abantu abadala. Ukuze Ukuyivavanya oku, ndilolonga database, aqulathe ulwazi oluneenkcukacha kwimikhwa ubuthongo iminyaka esithoba phantse 1600 US abantwana. Kwakhona ikwazile ukufumana iisampuli DNA ukusuka abantwana kwaye sihlaziye ubude telomere zabo.

Kwacaca ukuba zonke lixa ubuthongo kwakhokelela kokunciphisa telomere yi-1,5 ekhulwini. Oku, eneneni, ithetha ukuba aba abantwana bakhule ngokukhawuleza, nangona akucaci ukuba kangakanani.

Kutheni na ukuba abantwana wayelala inani elingonelanga iiyure asungule uthe isifo okanye imeko? Isizathu ilele iminyaka yabo encinane. Noko ke, oku akuthethi ukuba abantwana abanjalo abasesichengeni ngakumbi ezi zifo sele umdala.

Izazinzulu ziye zafumanisa akukho mahluko ukuba umbutho ngenxa yohlanga, isini okanye ubume zentlalo-qoqosho.

Bangaphi abantwana ukuba balale

Abantwana abangaphantsi kweminyaka-9 ubudala kufuneka ulale iiyure ubuncinane ezilithoba ngosuku, ngakumbi kukhethwa 10 okanye 11. Ngokwahlukileyo abadala, ngubani na buhlungu ubuthongo elide kakhulu, xa kufikwa abantwana, kokukhona balala ngcono.
