Ubuvuzi bwimitsi

Kimwe mu bice bitamenyekanye byumubiri kokuvura urumuriubushakashatsi bwasuzumye imitsi.Imitsi yimitsi yumuntu ifite sisitemu yihariye yo kubyara ingufu, ikeneye kuba ishobora gutanga ingufu mugihe kirekire cyokoresha igihe gito nigihe gito cyo kuyikoresha cyane.Ubushakashatsi muri kano karere bwihuse cyane mumyaka mike ishize, hamwe nubushakashatsi bushya bwo hejuru buri kwezi.Itara ritukura na infragre ryakozweho ubushakashatsi bwimbitse kuburwayi butandukanye, kuva kubabara hamwe kugeza gukira ibikomere, birashoboka ko ingaruka za selile zerekanwe gukora kurwego rwingufu.Niba rero urumuri rwinjiye mumitsi, birashobora kugira ingaruka nziza aho?Muri iyi ngingo tuzasuzuma uburyo urumuri rukorana na sisitemu ninyungu zishobora kuzana, niba zihari.

Umucyo urashobora gukorana n'imikorere y'imitsi, ariko gute?
Kugira ngo twumve uburyo urumuri rushobora kugira ingaruka kumitsi, dukeneye kubanza kumva uburyo imitsi ikora.Ingufu zirakenewe mubuzima muri buri selile yubwoko bwose tuzi ubu.Uku kuri kwubuzima kugaragara cyane mubice byimitsi, uhereye kumashini, kuruta ubundi bwoko bwimitsi.Kubera ko imitsi igira uruhare mukigenda, igomba kubyara no gukoresha ingufu, cyangwa ntizigenda.Ikintu cyose gifasha muri uyu musaruro wibanze uzaba ufite agaciro.

Uburyo bwo kuvura urumuri
Ubuvuzi bworoheje bufite uburyo buzwi cyane muri selile iyo ari yo yose yumubiri hamwe na mitochondrion (mitochondria ni organelles ishinzwe kubyara ingufu).Urashobora kureba muri Cytochrome C Oxidase na Nitric Oxide kugirango umenye byinshi byihariye hano, ariko mubyukuri hypothesis nuko urumuri rutukura ndetse na hafi-ya-infragre ifasha mitochondriya yacu kurangiza inzira yo guhumeka, igatanga CO2 na ATP nyinshi (ingufu).Ibi mubyukuri byakoreshwa mubice byose bigize umubiri, usibye abadafite mitochondriya nka selile zitukura.

Guhuza imitsi-imbaraga
Kimwe mu bintu by'ingenzi biranga ingirangingo z'imitsi ni uko ari nyinshi cyane muri mitochondriya, zikeneye kuzuza ingufu nyinshi zikenewe.Ibi bireba imitsi ya skeletale, imitsi yumutima, hamwe nimitsi yoroheje nkuko wasanga mubice byimbere.Ubucucike bwa mitochondriya mu ngingo z'imitsi buratandukanye hagati y'ibinyabuzima n'ibice by'umubiri, ariko byose bikenera imbaraga nyinshi zo gukora.Kubaho kwinshi muri rusange byerekana impamvu abashakashatsi bavura urumuri bashishikajwe no gukoresha imitsi yibasira, ndetse kuruta izindi ngingo.

Ingirangingo z'imitsi - gukura & gusana byongerewe urumuri?
Ingirabuzimafatizo ya Myosatellite, ubwoko bwimitsi yingirangingo igira uruhare mu mikurire no gusana, nayo ni intego nyamukuru yo kuvura urumuri1,5, wenda niyo ntego nyamukuru itanga ingaruka ndende.Utwo tugingo ngengabuzima dukora cyane mugusubiza ibibazo (nko kuva mumashini nko gukora siporo cyangwa gukomeretsa) - inzira ishobora kuzamurwa nubuvuzi bworoheje9.Kimwe n'ingirabuzimafatizo ahantu hose h'umubiri, utugingo ngengabuzima ni byo bibanziriza ingirabuzimafatizo zisanzwe.Mubisanzwe bibaho muburyo bwisanzuye, budakora, ariko bizahinduka izindi ngirabuzimafatizo cyangwa bihindure ingirabuzimafatizo zikora neza murwego rwo gukira, hasubijwe ibikomere cyangwa imyitozo.Ubushakashatsi buherutse gukorwa bwerekana ingufu za mito-iyambere mu ngirabuzimafatizo nkurwego rwibanze rwimibereho yabo6, cyane cyane igena 'programming' yabo hamwe n umuvuduko wabo.Kubera ko hypothesis iri inyuma yubuvuzi bwumucyo ari uko ishobora kuba imbaraga ziterambere ryimikorere ya mito-iyambere, uburyo busobanutse burahari bwo gusobanura uburyo urumuri rushobora kuzamura imikurire yacu no gusana hakoreshejwe ingirabuzimafatizo.

Umuriro
Gutwika nikintu gisanzwe kijyanye no kwangirika kwimitsi cyangwa guhangayika.Abashakashatsi bamwe batekereza ko urumuri rushobora gufasha (niba rukoreshejwe neza) kugirango rugabanye ubukana bwumuriro3 (nukwongera urugero rwa CO2 - hanyuma rukabuza guhagarika cytokine / prostaglandine), bityo bigatuma hasanwa neza nta nkovu / fibrosis。
