Ngaba wakha weva ngomhlaza wobuchopho? Enyanisweni yimeko eyingozi kakhulu kwaye inzima ukuyinyanga. Kuba ingqondo yethu yindawo ekhuselekileyo emzimbeni. Asikuko konke okunokungena lula apho. Ngenxa yolu khuselo, kwanamayeza asetyenziselwa umhlaza (i-chemotherapy) awakwazi ukufikelela kwiiseli zomhlaza ezikwingqondo. Kodwa ngoku izazinzulu zifumene isisombululo esimangalisayo koku.
Yintoni le Blood-Brain Barrier?
Ngamafutshane, oku kufana nodonga olukhuselekileyo olujikeleze ubuchopho bethu. Khawuthelekelele ukuba ubuchopho bethu sesona sakhiwo sibalulekileyo nesikhuselekileyo kweli lizwe. Umnyango wokungena kweso sakhiwo udlula ngesango eliqinileyo kakhulu. Eli sango lithintela iintsholongwane kunye neekhemikhali ezingafunekiyo egazini lethu ukuba zingangeni engqondweni. Oku sikubiza ngokuba yiBlood-Brain Barrier kunyango.
Olu khuseleko lubalulekile kuthi. Kodwa ingxaki kukuba, le nkqubo yokuzikhusela iphatha namayeza e-chemotherapy 'njengeendwendwe ezingafunekiyo' kwaye ayiwavumeli ukuba angene. Ngoko ke, ukunyanga umhlaza wobuchopho kube ngumceli mngeni wokwenene koogqirha.
Isisombululo samva nje sezazinzulu: Isixhobo esincinci esinyibilikayo!
Iqela lezazinzulu ngoku lifumene isisombululo esitsha kulo mceli mngeni: i-implant encinci enyibilikayo emzimbeni ize ifakwe ngaphakathi kwekhakayi, kufutshane nendawo apho kukho ithumba lobuchopho.
Le gadget incinci, ibhokisi encinci emalunga nesentimitha ububanzi, yenziwe nge-amino acid ekhethekileyo. Ibizwa ngokuba yi -glycine . Into ekhethekileyo ngayo kukuba xa kufakwa umbane omncinci kuyo, iyangcangcazela kwaye ikhuphe amaza esandi aphindaphindayo, okanye amaza e-ultrasound , angavakaliyo endlebeni yomntu. Le nkqubo ibizwa ngokuba yi-piezoelectric effect .
Ngoku khawucinge ukuba ugqirha ufaka iyeza lokulwa nomhlaza, elifana ne-paclitaxel, emzimbeni. Kwangaxeshanye, isixhobo esilawulwa ngaphandle sibonelela ngombane kuloo nto incinci engqondweni. Emva koko, amaza e-ultrasound akhutshwa yiyo abangela ukuba iiseli zeBlood-Brain Barrier esithethe ngazo zingcangcazele kancinci, zenze izithuba ezincinci phakathi kwazo. Ukuchaneka, kufana nesango elivalwe ngokuqinileyo elivuleka kancinci. Ngezo zithuba, amayeza omhlaza anokuya ngqo kwiiseli zomhlaza. Ayimangalisi loo nto?
Makhe sijonge ezinye zeenzuzo zale teknoloji intsha kwitheyibhile engezantsi.
| Uphawu | Inkcazo |
|---|---|
| Ithagethi | Amayeza athunyelwa ngqo kwiiseli zomhlaza wobuchopho. |
| ukhuseleko | Ayizilimazi izicwili zobuchopho ezisempilweni. |
| Izinto eziphathekayo | Yenziwe nge-glycine, eluncedo emzimbeni. |
| Iyabola | Ekuhambeni kwexesha, iyanyibilika emzimbeni ngaphandle kokubangela monakalo. Akukho mfuneko yokuphinda kwenziwe utyando ukuze isuswe. |
| Ulawulo | Oogqirha banokulawula ukuba esi sixhobo sifanele sisebenze ixesha elingakanani. |
Ukusetyenziswa ngokubanzi kwetekhnoloji ye-ultrasound
Le teknoloji ye-ultrasound ayintsha kwicandelo lezonyango. Sihlala sisiva ngayo xa kuhlolwa umntwana. Kodwa ngoku isetyenziselwa okungaphezulu koko. Ngokutsho kukaGqr. Neal Kassell, omnye weengcali zobuchwepheshe, kufana "nokusebenzisa iglasi yokukhulisa ukuze ugxile kwimitha yelanga kwaye utshise igqabi." Oko kuthetha ukuba amandla anokujoliswa ngokuchanekileyo, kuphela kwindawo oyifunayo. Ngoko ke ayonakalisi izicubu eziphilileyo ezijikelezileyo.
Oogqirha ngoku bayazi iindlela ezingaphezu kwama-30 ezahlukeneyo zokunxibelelana nezicubu besebenzisa ubuchwepheshe be-ultrasound, xa kuthelekiswa neendlela ezi-5 kuphela kwiminyaka elishumi eyadlulayo.
Ngolu lwazi, kunethemba lokuba obu buchwephesha bungasetyenziselwa ukunyanga kungekuphela nje umhlaza wobuchopho, kodwa nezifo zemithambo-luvo ezifana ne-Alzheimer's kunye ne-Parkinson's, umhlaza we-pancreatic kunye ne-prostate okunzima ukuwunyanga, kwanokuxhomekeka kwiziyobisi.
Ikamva lale teknoloji libonakala njani?
Simele sikhumbule ukuba oku kusesekwinqanaba lophando. Izazinzulu ziye zavavanya oku kwiimpuku kwaye zabona iziphumo eziphumeleleyo kakhulu. Xa zinikwa iyeza, iithumba zancipha kwaye ubomi bezilwanyana baphindaphindeka kabini. Kwanasemva kweenyanga ezi-6, akukho ziphumo zibikwe. Okulandelayo, iqela liceba ukuvavanya ukhuseleko kunye nokusebenza kwayo kwiihagu.
Isazinzulu esiphambili esafumanisa oku, uThanh Nguyen, unethemba lokwenza into efana ne-patch ngezi zixhobo zincinci kwixesha elizayo. Emva koko kuya kwenzeka ukujolisa nokunyanga iindawo ezahlukeneyo zobuchopho ngaxeshanye. Mhlawumbi le ndlela ingasetyenziselwa ukutshabalalisa naziphi na iiseli zomhlaza eziseleyo emva kokuba ithumba lobuchopho lisusiwe ngotyando.
Umyalezo Wokuya Ekhaya
- I-implant ebolayo ekuthethwa ngayo kweli nqaku yiteknoloji yanamhlanje ethembisayo kakhulu yokunyanga umhlaza wobuchopho.
- Oku kuquka ukusebenzisa amaza e-ultrasound ukuvula okwethutyana umqobo wegazi-ubuchopho , othintela amayeza okulwa nomhlaza ukuba angangeni engqondweni.
- Oku kusesekwinqanaba lophando , kwaye kuza kuthatha ixesha ngaphambi kokuba kusetyenziswe ebantwini.
- Oku kungasetyenziswa kwixesha elizayo njengokongeza okanye njengendlela yonyango olukhoyo olufana notyando lobuchopho, i-chemotherapy, kunye nonyango lwemitha.
- Ukuba wena okanye umntu omaziyo unenkxalabo malunga nesifo somhlaza, thetha ngaso nogqirha wakho ngalo lonke ixesha.
