Izingane abalele kancane, sikhule ngokushesha emangqamuzaneni

Ngokuvamile izingane ezincane kunzima ukubeka embhedeni, kodwa badinga ngempela. Ngaphandle ubuthongo ubuthi kungukuthi asuswe ingqondo, inkumbulo yesikhashana ingavuli ibe eside, ikhono ukucabanga engqondweni yethu nokuxazulula izinkinga ziyancipha, nobuchopho iqala ukubhubhisa uqobo.

Njengoba isifundo esisha, ogama Imiphumela yashicilelwa ephephabhukwini "Pediatrics", iphupho - liphinde indlela enhle ukunweba ukuphila kwakho. Ikakhulukazi, nokungalali ebuntwaneni kubangela ziwohloke masinyane esifundazweni DNA.

Kusukela lokho kuncike izinga sokuguga kwamangqamuzana?

Ucwaningo luye ngaphambili exhumene ukungalali ngokwanele nge rate nesanda sokuguga kwamangqamuzana. Lokhu kulinganisela ngokuvamile kunqunywa isimo telomere - izindawo enisemikhawulweni chromosome ethu.

Telomere (kusuka esiGrekini. "Ukuphela izingxenye") ukuvimbela i-fusion ngephutha wama-chromosomes elingumakhelwane umonakalo zabo zemvelo.

Senescence kuholela kokucindezelwa yalezi telomers, lapho-chromosomes ahlale olungavikelekile kanye zilinyazwa kalula. I emifushane le-telomere, indoda esikhulile.

Ngaphezu kwalokho, ama-telomere emifushane ukwandisa propensity yakho isifo senhliziyo, ukuthuthukiswa kuphazamiseka izinzwa, izinkinga ezingokwengqondo, kanti emdlavuzeni.

Kucwaningo olwenziwa eMelika

Iqembu lososayensi kusukela Princeton University wanquma ukuthola ukuthi ngabe lo mphumela laligujwa ezinganeni, hhayi nje abantu abadala. Ukuze ukuhlole lokhu, ngoba babebabheka database, eyayinekheli ukwaziswa okuningiliziwe ubuthongo imikhuba yiminyaka emakhulu asithoba cishe 1,600 US izingane. Futhi wakwazi ukuthola amasampula DNA kusukela izingane futhi sihlaziye ubude telomere yabo.

Kwavela ukuthi ihora ukungalali ngokwanele kwaholela ukuncipha kwe-telomere by 1.5 amaphesenti. Lokhu, empeleni, kusho ukuthi lezi zingane zikhula ngokushesha, nakuba akucaci ukuthi zithinteka.

Kungani izingane abalala anenombolo enganele amahora engazange asungule wathi isifo noma isimo? Isizathu itholakala ubudala babo encane. Nokho, lokhu akusho ukuthi izingane ezinjalo kusengozini kulezi zifo lapho usukhulile.

Ososayensi baye bathola ukuthi akukho mehluko ngoba inhlangano ngesisekelo uhlanga, ubulili noma isimo kwezenhlalo noma kwezomnotho.

Bangakhi bantfwana balale

Izingane ezingaphansi kweminyaka 9 ubudala kufanele ukulala okungenani amahora angu-ayisishiyagalolunye ngosuku nakakhulu mhlawumbe 10 noma ngisho 11. Ngokungafani nabantu abadala, abangakwazi ubuhlungu ubuthongo eside kakhulu, uma kuziwa ezinganeni, yilapho bezibona khona ukulala ngcono.
