Found mavhitaminzi kuti kuwedzera upenyu anotarisirwa

Paakanga achivaudza vanobudirira kutsvaka mushonga kusafa zvishoma vakurumidze, asi kubudirira chinokosha mukuedza ubvise rufu uye kukwegura yave asvika. Maererano nokumwe kuongorora itsva yakabudiswa mumagazini inonzi Science, rakanzi vhitamini nicotinamide riboside (NR) chakarasikirwa kukwanisa kukurudzira patsva kuti tsandanyama rinenge riri vakura mbeva, apo vachiwedzera lifespan yavo.

Kutaura ichi pachena budiriro, kutungamirira mutsvakurudzi Johan Averks akatsanangura kuti mushonga rokuzvivandudza rakaita kuti irambe anogona kuwana zvinokosha kubatsira basa iri. Anoti kuti zuva rimwe uchibatsirwa Mishonga zvokuwedzera, tinogona kuita pasina kuvhiyiwa.

Kugona panoda

Kufanana nedzimwe mhuka dzose, pamusoro upenyu munhu zvishoma nezvishoma anorasikirwa masero somugumisiro vasachembera. Izvi inonziwo muchitokisi rufu. Asi pane kungoti kufa, muviri wedu replenishes wayo romugove, kukurudzira kukura hunde masero.

Zvisinei, migumisiro yedu yepanyika hunhu ndechokuti pamusoro nguva, simba iri kuti panoda DZEMUNHU DZINODZORA, uye pakupedzisira inotungamirira rufu rwomuviri. Masayendisiti dzinofarira, kuwedzera upenyu hwevanhu. Saka, vari nguva kutsvaka nzira nokukurumidza kutanga kupora kwacho panongovira rwunotanga kumboderera. Remarudzi chikwata Vatsvakurudzi zvino anogona kuona pane chimwe chidimbu kubva dambanemazwi.

Chii chakavanzika mitochondria?

Maererano chikwata masayendisiti, kiyi rinoiswa mitochondria edu, izvo kazhinji vachinzi "zvirimwa simba" nemasero edu. Izvi zviduku organelles chamutsa simba rinodiwa kuti zvakawanda cellular kwendangariro. Kukura unyanzvi hunde masero Somuenzaniso, kunobva simba zvakapararira munyika mitochondria.

Zvakaonekwa kuti mitochondrial dysfunction mumwe zvinoratidza kuchembera. Saka, chidzidzo vanyori vakasarudza kutsvaka zvakananga kubatana pakati dysfunction ichi uye masero kukwanisa panoda, achitarisira kuwana nzira kuti vaigadzirise.

Kana hunde masero kuva, vanoshandisa mumatanda vanoda remubatanidzwa nicotinamide adenine dinucleotide (ZWL +). It unokosha mukuita kunowanzoitika kushanda mitochondria. Saka vaongorori vakasarudza kusuma akwegura nembeva NR, inova aizotangira kuna ZWL +, kuti ndione nomugumisiroi zvichataurirana nokugona kwavo nemoto tsandanyama masero.

migumisiro kudzidza

Zvabuda akaratidza kuti pashure vatarisire NR, makonzo vakakwanisa vaunze vazhinji tsandanyama hunde masero kuti gare gare kuva mukuru tsandanyama masero, kuwedzera kutsungirira kwavo uye ushande. Somuenzaniso, munguva pfupi vakakwanisa kushanda refu uye huchawedzera mberi.

Mbeva kubatwa NR, vaigara yakareba kupfuura vaya vasina kupiwa vhitamini, kungofanana muna _3. Zvinokosha kucherechedza kuti vanyori pakudzidza haana kuzivisa chinhu rwakashata nemishonga kunyange kana achiita panguva dzakakwirira mishonga pakati NR.

Zvechokwadi, zvakawanda basa chinodiwa usati nharo kuti masayendisiti akakwanisa kuva mushonga. Handiti, zvichigere kuzivikanwa kuti inoshanda kana njodzi, vhitamini ichi inogona kushandiswa pakurapa kukwegura kwevanhu.
