Icyizere gishya kuri kanseri y'ubwonko! Agakoresho gato gashonga (Biodegradable Brain Implant)

Wigeze wumva inkuru ya kanseri yo mu bwonko? Mu by’ukuri ni indwara iteje akaga cyane kandi igoranye kuyivura. Kubera ko ubwonko bwacu ari bwo burinzwe cyane mu mubiri. Si ibintu byose bishobora kwinjiramo byoroshye. Kubera ubwo burinzi, ndetse n’imiti ikoreshwa muri kanseri (chimiotherapie) ntishobora kugera ku tunyangingo twa kanseri mu bwonko. Ariko ubu abahanga mu bya siyansi babonye igisubizo gitangaje kuri ibi.

Iyi miyoboro y'ubwonko n'amaraso ni iki?

Mu magambo make, ibi bimeze nk'urukuta ruzengurutse ubwonko bwacu. Tekereza ko ubwonko bwacu ari bwo bw'ingenzi kandi bufite umutekano mu gihugu. Irembo ry'iyo nyubako rinyura mu irembo rihamye cyane. Iri rembo ribuza mikorobe n'imiti idakenewe mu maraso yacu kwinjira mu bwonko. Ibi ni byo twita Umugozi w'ubwonko n'amaraso mu buvuzi.

Ubu burinzi ni ingenzi kuri twe. Ariko ikibazo ni uko, ubu buryo bwo kwirinda bufata ndetse n'imiti ya chimiotherapie nk' 'abashyitsi badakenewe' kandi ntibubemerera kwinjira. Bityo, kuvura kanseri yo mu bwonko byabaye ikibazo gikomeye ku baganga.

Umuti uheruka w’abahanga mu bya siyansi: Akantu gato gatera intanga gashonga!

Itsinda ry'abahanga mu bya siyansi ubu ryabonye igisubizo gishya kuri iki kibazo: agakoresho gato gashongera mu mubiri kagashyirwa mu gahanga, hafi y'aho ikibyimba cyo mu bwonko kiri.

Aka gakoresho gato, gafite ubugari bwa santimetero imwe gusa, kakozwe muri aside amine yihariye. Kitwa glycine . Ikidasanzwe kuri ko ni uko iyo umuriro muto w'amashanyarazi ushyizwe kuri ko, karahinda umushyitsi kandi kagatanga amajwi menshi, cyangwa amajwi ya ultrasound , atumvikana n'ugutwi kw'umuntu. Iyi nzira yitwa piezoelectric effect .

Noneho tekereza ko muganga ashyize umuti urwanya kanseri, nka paclitaxel, mu mubiri. Muri icyo gihe, igikoresho gikoreshwa inyuma gitanga amashanyarazi kuri ako gakoresho gato kari mu bwonko. Hanyuma, imiraba ya ultrasound isohokamo ituma uturemangingo twavuze dutigita gato, bigatuma hagati yatwo habaho icyuho gito. Mu by'ukuri, ni nk'aho irembo rifunze cyane rifunguka gato. Binyuze muri ibyo cyuho, imiti ya kanseri ishobora kujya mu turemangingo twa kanseri. Ntabwo ari igitangaza?

Reka turebe bimwe mu byiza by'iri koranabuhanga rishya mu mbonerahamwe iri hepfo.

Ikoreshwa rya ikoranabuhanga rya ultrasound rikwirakwira cyane

Ubu buryo bwa ultrasound si bushya mu rwego rw'ubuvuzi. Twakunze kubwumva mu gupima abana. Ariko ubu burimo gukoreshwa byinshi kurusha ibyo. Nk'uko Dr. Neal Kassell, umwe mu bahanga mu ikoranabuhanga abivuga, ni nko "gukoresha ikirahuri gisa n'ikirahuri gikurura imirasire y'izuba no gutwika ikibabi." Ibyo bivuze ko ingufu zishobora kwerekezwa neza cyane, gusa ku kintu wifuza. Bityo rero ntibigire ingaruka mbi ku mubiri muzima ukikije.

Hamwe n'ubu bumenyi, byifujwe ko iri koranabuhanga rishobora gukoreshwa mu kuvura kanseri yo mu bwonko, ndetse no mu kuvura indwara z'imitsi nka Alzheimer na Parkinson, kanseri ya pancreas na prostate igoye kuvura, ndetse no mu kuba imbata y'ibiyobyabwenge.

Ejo hazaza h'iri koranabuhanga hameze gute?

Tugomba kwibuka ko ibi bikiri mu cyiciro cy’ubushakashatsi. Abahanga mu bya siyansi babipimye ku mbeba kandi babonye umusaruro mwiza cyane. Iyo bahawe uyu muti, ibibyimba byaragabanutse kandi igihe cyo kubaho cy’inyamaswa cyikubye kabiri. Ndetse na nyuma y’amezi 6, nta ngaruka mbi zagaragaye. Hanyuma, itsinda rirateganya gupima umutekano n’ubushobozi bwabyo ku ngurube.

Umuhanga mu bya siyansi wavumbuye ibi, Thanh Nguyen, yizeye gukora ikintu kimeze nk'agace gafite utu duce duto twinshi mu gihe kizaza. Hanyuma bizashoboka kwibasira no kuvura ibice bitandukanye by'ubwonko icyarimwe. Wenda ubu buryo bushobora gukoreshwa mu gusenya uturemangingo twa kanseri dusigaye nyuma yo kubagwa ikibyimba cyo mu bwonko.
