Varume nevakadzi vanogona kuwana vhudzi rakachena nezera remakore makumi matatu, nekutaura kwevabereki kune vhudzi rakachena kuva chiratidzo chakanaka che "nguva" iyo ichaitika. Zvisinei, kunyange ne genetics kutamba basa guru mune izvi, the kushungurudzika imbiru inokoshawo. 1b1yv
Uye kusvikira ipapo, masayendisiti aiziva kuti izvi zvakaitika, asi vakanga vasina tsanangudzo chaiyo. Zvinoitika kuti kudzidza yakaitwa nevatsvakurudzi kubva Harvard University uye kubva Faculty of Medicine yeRibeirão Preto (FMRP-USP) yakaona kuti maitiro aya anoshanda sei. The Brazilian Thiago Mattar Cunha yakashanda nemarabhoritari eAmerica kuita bvunzo nyowani uye kusvika pamhedzisiro yakafanana nevatorwa.
Pakuyedza nemakonzo vakaona kuti painge papinda masero anogadzira melanin (izvo zvinokonzeresa bvudzi uye ruvara rweganda) uye kunzwira tsitsi tsinga, iyo inotarisira kupukunyuka kwemuviri. Kana yaiswa pasi pekunetsekana, tsinga idzi dzinobuda noradrenaline, iyo inotorwa ne pigment- regenerating stem cells.
Kukonzera marwadzo mu (varombo) rabhoritari makonzo, pakanga pane kusunungurwa kwe adrenaline e cortisol, zvichiita kuti mwoyo uwedzere uye kuwedzera kweropa - mune mamwe mazwi, kushungurudzika kunokonzerwa nekukanganisa hurongwa hwemagetsi. Izvi zvakakonzera bvudzi jena iro, maererano Bing Zhang (munyori anotungamira wechidzidzo), vane "kukuvara zvachose" uye havagone kudzoreredzwa pigment yavo.
Sayenzi yebvudzi rinopesana nechena 3d2p27
Mumiyedzo yakaitwa nemakonzo pasi pesimba re antihypertensives, migumisiro yacho yakabviswa. Nekuenzanisa majini embeva yakaedzwa nemamwe, puroteni yakakuvadza maseru inogona kuzivikanwa. Apo iyi protein (CDK, kana cyclin-dependent kinase) yakadzvinyirirwa, kurapwa kwakakwanisa kudzivirira kuchinja kwebvudzi jena.
Ikozvino kune kuvhurwa kwesainzi: ingoongorora chemistry inotarisira puroteni kudzivirira grey bvudzi. Mudzidzisi Ya-Cieh Hsu, anobva kuHarvard, anotsinhira mubvunzurudzo na BBC kuti zvakawanikwa"hausi mushonga kuitira kurapwa kwebvudzi", uku kuri "kutanga kwerwendo rurefu rwekutsvaga kutsvaga kupindira kwevanhu. Izvi zvinopawo pfungwa yekuti kushungurudzika kunogona kukanganisa sei dzimwe nhengo dzemuviri wedu. "
Zvakakosha kusimbisa kuti mhinduro chete yevhudzi jena rinokonzerwa nekukwegura, kubva pakuona kwesayenzi yemazuva ano, ichiri kuidhaya (kana shandura ruvara rwebvudzi neugmented reality) Zvisinei, maererano nebhuku ra Nhau dzeUrapa Nhasi, kudya zvikafu zvakapfuma mune antioxidants senge green tea, michero nemiriwo inzira yeku kuderedza kushungurudzika oxidative. Kuperevedza kweprotein kunogonawo kuva chinhu chinowedzera, semashoko anozivisa - kugadzirisa chikamu ichi, rwendo rwekuenda kune nutritionist rwakakwana!
Chidzidzo cheHarvard chakatumirwa muna Chivabvu 2019 uye chakangogamuchirwa muna Zvita, chichiburitswa nezuro (22) uye chinogona kuoneka zvizere kuburikidza. Masango.com (muChirungu).
