Anthu ambiri sadziwa zimenezi, koma anthu ena sagwirizana nazozitsulo.Malinga ndi mbiri yomwe yatulutsidwa m'nkhani yatsopano, khumi mwa anthu a ku Germany amadana ndi nickel.
Koma ma implants azachipatala amagwiritsa ntchito faifi tambala.Ma aloyi a Nickel-titaniyamu akugwiritsidwa ntchito mochulukira ngati zida zopangira ma implants amtima m'machitidwe osasokoneza pang'ono, ndipo pambuyo pa kuyika, ma aloyiwa amatulutsa faifi tating'ono chifukwa cha dzimbiri.Kodi ndizowopsa?
Gulu la ofufuza ochokera ku Jena, Prof. Rettenmayr ndi Dr. Andreas Undis, linanena kuti mawaya opangidwa kuchokera ku nickel-titanium alloy amatulutsa faifi tating'ono kwambiri, ngakhale kwa nthawi yaitali.Nthawi yoyesera yotulutsa zitsulo ndi masiku ochepa chabe, monga momwe boma limafunira kuti avomereze implants zachipatala, koma gulu lofufuza la Jena linawona kutulutsidwa kwa nickel kwa miyezi isanu ndi itatu.
Cholinga cha phunziroli ndi waya wochepa thupi wopangidwa ndi superelastic nickel-titanium alloy, yomwe imagwiritsidwa ntchito, mwachitsanzo, ngati mawonekedwe a occluder (awa ndi ma implants azachipatala omwe amagwiritsidwa ntchito kukonza vuto la septal mtima).Kachingwe kakang'ono kaŵirikaŵiri kamakhala ndi mawaya ang'onoang'ono awirimauna“maambulera” pafupifupi kukula kwa ndalama ya yuro.The superelastic implant imatha kukokedwa mwamakina mu waya woonda womwe utha kuyikidwa mu catheter yamtima."Mwanjira iyi, occluder akhoza kuikidwa ndi njira yochepetsera pang'ono," adatero Undisch.Moyenera, implant idzakhalabe mwa wodwalayo kwa zaka kapena zaka zambiri.
Occluder yopangidwa ndi nickel-titanium alloy.Ma implants achipatalawa amagwiritsidwa ntchito kukonzanso septum yamtima yomwe ili ndi vuto.Ngongole: Chithunzi: Jan-Peter Kasper/BSS.
Undis ndi wophunzira udokotala Katarina Freiberg amafuna kudziwa zomwe zidachitikira waya wa nickel-titaniyamu panthawiyi.Anapereka zitsanzo zamawaya ndi njira zosiyanasiyana zamakina ndi matenthedwe kumadzi a ultrapure.Kenako adayesa kutulutsidwa kwa nickel kutengera nthawi yomwe idakonzedweratu.
Undish anati: “Zimenezi si zazing’ono, chifukwa zitsulo zimene zimatuluka nthawi zambiri zimakhala pamlingo wokwanira kuzizindikira.”, adakwanitsa kupanga njira yoyesera yoyezera kutulutsa kwa nickel.
"Kawirikawiri, m'masiku oyambirira ndi masabata, malingana ndi chithandizo chamankhwala chisanachitike, nickel yochuluka imatha kumasulidwa," Undisch ikufotokoza mwachidule zotsatira.Malinga ndi asayansi azinthu, izi zimachitika chifukwa cha katundu wamakina pa implant panthawi ya opareshoni."Kusintha kumawononga gawo lopyapyala la oxide lomwe limaphimba zinthuzo.Zotsatira zake ndi kuwonjezeka kwapachiyambinickelkuchira.”nickel timayamwa kudzera mu chakudya tsiku lililonse.
Mu Science 2.0, asayansi ndi atolankhani, opanda kukondera pazandale kapena kuwongolera mkonzi.Sitingathe kuchita izi tokha, kotero chonde chitani mbali yanu.
Ndife osachita phindu, Gawo 501 (c) (3) bungwe lankhani za sayansi lomwe limaphunzitsa anthu opitilira 300 miliyoni.
Mutha kuthandizira kupanga zopereka zopanda msonkho lero ndipo zopereka zanu zipita 100% kumapulogalamu athu, opanda malipiro kapena ofesi.
