Masayendisiti akawana humbowo hwekuti kufungisisa kwakabatana nekuwedzera kwehupenyu hwekutarisira uye nekuvandudza kugona kwekuziva mukukwegura.
Iwe pamwe wakambonzwa kanopfuura kamwe nezve zvakawanda zvakanaka mhedzisiro iyo yekufungisisa maitiro inogona kuunza. Pamwe unotoverenga muzvinyorwa zvangu panhau iyi. Semuenzaniso, kutsva kutsva kunoratidza kuti kufungisisa kunogona kudzora kushushikana nekushushikana, kudzikira kweropa, uye kuita kuti unzwe kufara.
Zvakazoitika kuti kufungisisa kunogona kuita zvakawanda: zvinogona kubatsira kudzora kukwegura uye kuvandudza hunhu hwekuziva zviitiko mukukwegura. Izvi zvinogoneka sei?
- Deredza pasi kukwegura kwemasero
Kufungisisa kunokanganisa mamiriro edu epanyama nenzira dzakasiyana siyana, kutanga kubva padanho remaseru. Masayendisiti anosiyanisa kureba kwetelomere uye telomerase mwero sezviratidzo zvekukwegura kwemasero.
Masero edu ane ma chromosomes, kana kuteedzana kweDNA. Telomeres ipuroteni inodzivirira "cap" kumagumo etambo dzeDNA izvo zvinogadzira mamiriro ekuwedzera kudzokororwa kwesero. Iyo yakareba iyo telomeres, iyo yakawanda nguva iyo sero inogona kuzvipatsanura nekuzvivandudza yega. Nguva imwe neimwe masero paanowanda, kureba kwetelomere - uye nekudaro hupenyu - kunopfupika. Telomerase i enzyme inodzivirira kupfupisa telomere uye inobatsira kuwedzera hupenyu hwemasero.
Izvi zvinoenzana sei nehurefu hwehupenyu hwemunhu? Icho chokwadi ndechekuti kupfupiswa kwetereomere kureba mumasero kunoenderana nekudzikira mukushanda kwema immune system, kukura kwezvirwere zvemoyo nemitsipa uye zvirwere zvinodzikira senge osteoporosis uye chirwere cheAlzheimer. Iyo ipfupi kureba kwetelomere, ndipo panowedzera maseru edu anokwanisa kufa, uye isu tinotapurika nechirwere nezera.
Kufupisa kweTelomere kunoitika zvakasikwa patinokwegura, asi kutsvagisa kwazvino kunoratidza kuti maitiro aya anogona kukwidziridzwa nekushushikana.
Kungwarira maitiro kunosanganisirwa nekuderedzwa kwekufunga kwekufungidzira uye kushushikana, saka muna2009 rimwe boka rekutsvagisa rakaratidza kuti kufungisisa kwepfungwa kunogona kuve nekwaniso yekuva nemhedzisiro yakanaka pakuchengetedza telomere urefu uye telomerase mazinga.
Muna 2013, Elizabeth Hodge, MD, purofesa wezvepfungwa paHarvard Medical School, akaedza iyi fungidziro nekuenzanisa kureba kwetereomere pakati pevashandi vekufungisisa-mutsa wekufungisisa (metta kufungisisa) nevaya vasingadaro. Mhedzisiro yacho yakaratidza kuti vane ruzivo rwekufungisisa vezvemata vanowanzove netelomeres dzakareba, uye vakadzi vanofungisisa vane telomeres dzakareba zvakanyanya zvichienzaniswa nevakadzi vasiri kufungisisa.
- Kuchengetedzwa kwehuwandu hwegrey uye chena nyaya muuropi
Imwe nzira yekufungisisa inogona kubatsira kunonoka kukwegura iri kuburikidza nehuropi. Kunyanya, iro vhoriyamu regrey uye chena nyaya. Grey nyaya inoumbwa nemaseru ehuropi uye dendrites ayo anotumira uye anogamuchira masaini kuma synapses kutibatsira kufunga nekushanda. Ichena nyaya inoumbwa nemaazoni anotakura chaiwo magetsi magetsi pakati pendendende. Kazhinji, vhoriyamu yegrey nyaya inotanga kudzikira pazera remakore makumi matatu pamatanho akasiyana uye munzvimbo dzakasiyana, zvichienderana nehunhu hwako. Panguva imwecheteyo, isu tinotanga kurasikirwa nehukuru hweiyo chena nyaya.
Chidiki asi chiri kukura chemuviri wekutsvagisa chinoratidza kuti kuburikidza nekufungisisa isu tinokwanisa kugadzirisa huropi hwedu uye zvinogona kudzora kudzikira kwekuumbwa.
Mune chidzidzo na Massachusetts General chipatara mukubatana neHarvard Medical School muna 2000, masayendisiti akashandisa magnetic resonance imaging (MRI) kuyera ukobvu hwecortical grey uye chena nyaya yehuropi mumafungidziri uye vasiri-vafungidzi vezera rakasiyana. Mhedzisiro yacho yakaratidza kuti avhareji yecortical ukobvu muvanhu vari pakati pemakore makumi mana nemakumi mashanu vanofungisisa akaenzana neayo evanofungisisa nevasiri-vafungidzi pakati pemakore makumi maviri nemakumi matatu. Muitiro wekufungisisa panguva ino yehupenyu unobatsira kuchengetedza chimiro chehuropi nekufamba kwenguva.
Izvi zvakawanikwa zvakakosha zvekuti zvinokurudzira masayendisiti kuti awedzere kutsvagisa. Mibvunzo inomirira mhinduro dzesainzi ndeyekuti zvakawandisa sei kufungisisa kuti uwane mhedzisiro yakadaro, uye ndedzipi mhando dzekufungisisa dzine chinonyanya kukosha pahunhu hwekweguru, kunyanya kudzivirira kwezvirwere zvinodzikira senge chirwere cheAlzheimer.
Isu takajaira iyo pfungwa yekuti mitezo yedu nehuropi nekufamba kwenguva zvinotevera nzira yakajairika yekusimudzira uye kuora, asi humbowo hutsva hwesainzi hunoratidza kuti kuburikidza nekufungisisa tinokwanisa kudzivirira maseru edu kubva mukukwegura kusati kwasvika nekuchengetedza hutano mukukwegura.
