Ukuthembisa ngonyango lwemfuza ukubuyisela ukuva kubantwana abangevayo

Ulingo lwezonyango oluphambili olusebenzisa unyango lwemfuza lubuyisele ukuva kubantwana abahlanu abazelwe bezizithulu. Emva kweenyanga ezintandathu, aba bantwana baye bakwazi ukuyibona intetho baze baqhube iincoko, nto leyo ephakamisa ithemba lokusetyenziswa kwayo ngokubanzi kwixesha elizayo elingekude, ngokutsho kwapapashwa yiNew Atlas website, becaphula iphephancwadi elithi Science Advances.

Imeko yelifa

Izigulana kulingo zithwaxwa yimeko yemfuza ebizwa ngokuba yi-autosomal recessive deafness 9 (DFNB9), ephuma kuguqulo lwemfuza ebizwa ngokuba yi-OTOF, evelisa iprotein otoferlin, enceda ukuhambisa umbane osuka kwicochlea usiya ebuchotsheni, apho unako Iza kutolikwa njengesandi – kodwa ngaphandle kwayo, loo miqondiso ayisayi kufika apho. Ngenxa yokuba ibangelwa yinguqu enye kwaye ayibandakanyi nawuphi na umonakalo owenziwe emzimbeni kwiiseli, iqela lithi i-DFNB9 ngumgqatswa ofanelekileyo wolu hlobo lonyango lwemfuza.

Kuphononongo oluqhutywe ngabaphandi abavela kwiHarvard Medical School, Massachusetts Eye and Ear, kunye neFudan e-China, unyango lwemfuza lubandakanya ukupakishwa kofuzo lwe-OTOF kubathwali bentsholongwane kunye nokutofa umxube kulwelo lwangaphakathi lwendlebe. Iintsholongwane emva koko zafuna iiseli kwi-cochlea kwaye zafaka i-gene kuzo, zibavumela ukuba baqale ukwenza iprotheni ye-autoferlin engekhoyo kunye nokubuyisela ukuva.

Ukufakelwa kweCochlear

Abantwana abathandathu, abaphakathi konyaka omnye ukuya kwesixhenxe, aba-DFNB9 yabo yabashiya bengeva ngokupheleleyo nabo bathathe inxaxheba kuphononongo. Izigulana ezine zafakelwa izixhobo zokufakela i<em>cochlear, eziye zayidlula le ngxaki zize zikwazi ukufunda ukuva intetho nezinye izandi. Kule meko, uqhaqho-fakelo lwayekwa.

uphuculo olumangalisayo

Emva konyango lwemfuza, abantwana balandelwa kangangeeveki ezingama-26. Ngelo xesha, abahlanu kwabathandathu babonisa ukuphucuka okuphawulekayo, kunye nabantwana abathathu abadala abakwazi ukuqonda nokuphendula intetho, ngelixa ababini bekwazi ukuyithatha kwigumbi elinomsindo kwaye baqhube incoko kwifowuni. Abanye babantwana babebancinane kakhulu ukuba benze iimvavanyo eziqhelekileyo, kodwa bafunyanwa besabela kwizandi, bade baqalise ukuthetha amagama alula afana nelithi “mama.” Uphuculo lwenziwa kancinci kancinci, kodwa iqela lanika ingxelo yokuba abantwana baqale ukubonisa iziphumo phambi kovavanyo lokuqala kwiiveki ezine kamva.

Izizathu zemfuzo kunye nokuguga

UYilai Xu, umphandi ophambili kolu phando, uthe abathathi-nxaxheba kolu vavanyo baya kuqhubeka bebekwe iliso, ngelixa izifundo ezilandelelweyo ziyakuqhutywa kwabanye abantu. Eli qela lithi ukuvunywa konyango eUnited States kusenokuthabatha phakathi kweminyaka emithathu ukuya kwemihlanu. Unyango olufanayo lwemfuza luvavanyelwe ufuzo okanye ukulahleka kokuva okunxulumene neminyaka.
