Ososayensi abavela eCalifornia bakholelwa ukuthi bathole indlela yokuhambisa amaseli akhiqiza i-insulin ezigulini ezingasebenzi kuwo. Ngaphezu kwalokho, abakhiqizi bazozivikela ngokwenqatshwa komzimba. Le ndlela iveza esinye sezixazululo ezithembisayo ezisezinhlelweni zentuthuko, noma kunjalo, abantu abakakahlolwa. Uma kuphumelela, lokhu kuzokwenza impilo ibe lula kubantu abanesifo sikashukela sohlobo 1.
Njengamanje, iziguli ezinalolu hlobo lwesifo sikashukela kufanele zilinganise amazinga kashukela egazi futhi, uma kunesidingo, zinikeza umzimba nge-insulin eyengeziwe ngomjovo. Inani lososayensi abaningi bakha umshini ozoletha inqubo esezingeni lokuzenzakalelayo.
Kodwa-ke, uCrystal Nightray, umsunguli kanye noMphathi Omkhulu wephrojekthi entsha yeSan Francisco-based Encellin biotech, wanquma ukungasebenzisi umshini wokwelapha isifo sikashukela.
Eminyakeni embalwa ngaphambili, i-Nightray yanquma ukusebenza ngamaseli aphilayo. Esikhwameni esivumelekile, esasilingana nohlamvu lwemali, amangqamuzana ayequkethwe kuwo angaba khona ngokuphepha, ngenkathi ethula i-insulin, abacwaningi bagcizelela. Ngasikhathi sinye, kukhona ukuvikelwa ekwenqatshweni ngokugonywa.
Izilingo zemitholampilo lapho amaseli we-pancreatic afana nenqubo yokufakwa kweziguli ezinesifo sikashukela sezenziwe eminyakeni eminingana ngaphambili, futhi ziye zaphumelela. Kodwa-ke, amasosha omzimba alabo abatholayo aba nokuphendula okunzima kumaseli afakiwe. Iningi leziguli ngasikhathi sinye badinga ukuqhubeka nokusebenzisa i-insulin njalo.
UNitray nozakwabo bakwazile ukuthuthukisa indlela lapho amaseli e-pancreatic aphilayo ahlanganisa khona elukhunjini olunwebekile ukuze afakwe ngaphansi kwesikhumba. I-insulin neglucose ingangena ngaphakathi kolwelwesi, futhi amaseli angamasosha omzimba omtholi awangeni, okusho ukuthi ukwaliwa akunakwenzeka.
"Ungakucabanga ngale ndlela. Kubukeka sengathi uhleli ekhaya unefasitela elivulekile, kepha kukhona inethi yezinambuzane. Uzwa umoya, umoya, kepha izinambuzane azikuhlukumezi, ngoba azikwazi ukunqamula inethi," kusho umbhali walolu cwaningo.
Kuqala, ozakwabo abaphezulu baphoxisa uKnightray kusuka kulo mbono, ngenxa yokwehluleka ukudala izindawo zokugcina zokwenziwa kumaseli ngaphambili. Kodwa-ke, lona wesifazane uqhubeke nokusebenza kulo msebenzi. Ekugcineni, ukhombisile ukuthi kusetshenziswe ulwelwesi olunwebekile, amaseli ayaqhubeka nokuphila, futhi awabi sengozini yezempilo, ngoba i-medium eyakhiwe ifana kakhulu namanyikwe.
Okwamanje, ukuhlolwa sekuvele kwenziwa ezilwaneni zohlobo lwaselabhoratri, futhi umphumela uyathembisa kakhulu. Ngokuka-Nightray, uhlela ukwethula indlela yokusebenza kwezokwelapha ngeminyaka embalwa.
