Isikhathi sokuphila siyisimo lapho izici eziningi ezithinta khona: ezemvelo, zokuziphatha, ezenhlalo - kanye nokudla. Kukholelwa ukuthi ukudla kusiza ukwelula impilo futhi kuvikele ukubukeka kokufa. Kodwa-ke, ososayensi bafakazele: Ukudla - kude nento esemqoka.
Umqondo wokuguga wesimanje wesimanje
Ukuguga kwamaselula kungukuwohloka kancane kwezici ezingeni leselula nasezingeni lomzimba. Sekukonke, emcabangweni womkhawulo we-heiflicili, kunciphisa inani lokuhlukaniswa kwamaseli ezingeni le-DNA, kunezigaba ezintathu zokuguga kweselula:
1) Ukunciphisa i-molecule yamaprotheni ahambisana nokuphindaphinda kwe-DNA
2) inciphise ukuhlanganiswa kwe-rna kanye namaprotheni ahlobene ahlobene
3) Ukunciphisa ijubane eliphelele le-protein synthesis
Kukholakala ukuthi ukuguga kuhlotshaniswa nenqubo ye-oxidation. Umbono wezindlela ezisebenzayo ze-oksijini (AFC) uthatha ukuthi ama-radicals wamahhala adala ukulimala kwamazinga amaselula kanye nezicubu. Ukululama ngemuva kwe-microtravum, umzimba uhlanganisa amaseli amasha, kepha ngenxa yemikhawulo yemvelo yomjikelezo we-Division ngokuhamba kwesikhathi, iyayeka ukubhekana nakho. Bese kuba nokugula okuyingozi: ukulimala kwamathambo namalunga, ama-tumors nokunye.

Lokho Ososayensi Abakushoyo
Ungathola izinto eziningi lapho uMkhandlu Omkhulu Wababhali - kunemifino eminingi, izithelo namajikijolo. Kodwa-ke, izinkomishi ze-Blueberry azanele ukumisa inqubo enamandla yemvelo. Ukudla okunempilo kuthinta impela inhlala-kahle yethu, amandla emisipha, ijubane lokucabanga nezinye izinto, kodwa akunakusinika impilo yaphakade. I-mitochondrial theory ye-radical agen (MFRTA), ehlongozwe okokuqala ngawo-1950s, njengoba saphawula ngenhla, sichaza inqubo yokuguga ngenxa ye- "oxidative stress". Lo mbono uqinisekiswa yimiphumela ethile yelabhoratri, lapho babona khona ukuthembela kokulindelwe kwempilo yesilwane kusuka ku-metabolic rate yayo. Ucwaningo luphinde lwabonisa ukuthi ukwanda kwezinga lama-antioxidants ezilwaneni kwandisa isikhathi sezimpilo zabo.
Umkhawulo wamandla wasungulwa njengento ephambili ebambezela ukukhiqizwa kwezindlela ezisebenzayo ze-oxygen (AFC), okuyizinto ezivame kakhulu zamahhala emzimbeni - zibangela ukuguga.
Izikhala emcabangweni
Kubukeka sengathi ungahlala endaweni futhi uyeke ukuhlola lesi sihloko ngokwamukela umbono we-axoma. Kodwa-ke, ososayensi banquma ukuhlola lesi sihloko esijulile: Eminyakeni yamuva nje, bavote abacwaningi be-MFRTA futhi babona ukuthi akuwona wonke amalungiselelo omqondo ahlangana ngokuzijwayeza. Izifundo ezinemininingwane enemininingwane ezingokoqobo ezilwaneni ziphakamisa ukuthi izilwane ezinde ezinamakhaza zinezinga eliphansi lomonakalo ku-AFC kungenxa yokuthi umzimba wazo ngokwemvelo ukhiqiza ama-radicals angaphansi. Eqinisweni, konke ukuxhumeka komonakalo oxidative nokuphila isikhathi eside kuyachithwa.

Okuthinta ngempela ukuguga
Yize uMfrta wayengumqondo wesayensi osebenzayo futhi othuthukile, ngokushesha amalungiselelo aphikisanayo azokhonjwa ososayensi ngokuhlukumeza. Ngakho-ke shiya izengezo ezibizayo zamashalofu ezitolo - awuzidingi. Ngokuqondene nomuthi wentsha kanye nobungqabavu esezinqolobaneni ezindala, into esemqoka yizakhi zofuzo ezinhle nokuzivocavoca njalo.
