ʻO nā suture ʻokiʻoki e wikiwiki i ka hoʻōla ma hope o ka hana

Ua hana nā mea noiʻi ma Massachusetts Institute of Technology i nā sutures dissolvable i hiki ke hoʻouka ʻia me nā mea ʻike molekala a i ʻole nā ​​​​lāʻau lapaʻau inā pono.

ʻO ka manaʻo o ka hana hou e wikiwiki i ka hoʻihoʻi ʻana ma hope o ka ʻoki ʻana a i ʻole ka ʻike ʻana i nā leaka a i ʻole nā ​​​​hewa i ka pūnaewele ʻoki, e like me ka mea i paʻi ʻia e New Atlas, e haʻi ana i ka puke pai Matter.

Helene kahiko

Wahi a ke kahuna lapaʻau Helene ʻo Galen o Pergamon i Helene kahiko, i ka wā i loaʻa ai i ka poʻe gladiator kahi ʻeha i ʻoki ʻia, ua hoʻohana nā lāʻau lapaʻau i nā kaula i hana ʻia i ke kilika a me nā ʻōpū o nā hipa a i ʻole nā ​​​​lio e mālama i ka ʻeha. Ua kapa ʻia ʻo "Cat Guts" ʻo "Cat Guts" nā ʻoki a me nā fibers, ʻoiai ʻaʻole pili kekahi o lākou i nā ʻāpana o loko o nā ʻano holoholona.

Pukiki a pipi paha

ʻO ka inoa e pili ana i ka ʻōpū o nā pōpoki a i ʻole nā ​​ʻohana pipi, ʻo ia hoʻi "cat gut" e pili ana i nā pōpoki ma ka ʻōlelo Pelekania, a i ʻole ka pipi i ka pōkole no ka pipi. Ke hoʻohana mau ʻia nei kahi mana o nā humuhumu i kēia mau lā i kekahi mau ʻoki ʻana, ʻoi aku hoʻi i nā hihia kahi hiki ʻole ke wehe maʻalahi i nā sutures, no ka mea, e hemo maoli nā sutures ma kahi o 90 mau lā.

ʻO nā biomolecules a me nā hydrogels

I ka hoʻāʻo ʻana e hoʻonui i ka hoʻohana ʻana i nā sutures bio-soluble, ua lawe ka poʻe noiʻi MIT i ka ʻiʻo puaʻa a hoʻohana i kahi kaʻina hana hoʻomaʻemaʻe no ka holoi ʻana a hoʻopau i nā ʻāpana, e kiʻi i nā fibers i hana nui ʻia me ka collagen a me nā biomolecules ʻē aʻe. ʻO nā fibers, i kapa ʻia lākou ʻo De-gut, ua hoʻopili ʻia i loko o kahi hydrogel ma mua o ka hoʻokomo ʻia ʻana i loko o nā molekala like ʻole i ka gel e kōkua ai i ka ho'ōla ʻana a me ka ʻike.

gel poli

"ʻO kahi suture biodegradable [ʻokiʻoki] i hoʻololi ʻia me kahi papa hydrogel e hiki ke lawelawe ma ke ʻano he pūnāwai no nā mea ʻona ʻona, a i ʻole nā ​​​​lāʻau lapaʻau e like me nā antibodies monoclonal e mālama ai i ka mumū," i ʻōlelo ai ʻo ia, me ka hoʻohui ʻana "he mea kupaianaha ia [ʻo nā sutures hou] loaʻa nō hoʻi i ka hiki ke mālama i nā cell viable no ka manawa lōʻihi.

ʻike i nā maʻi maʻi

No ka noiʻi sensor, ua hoʻokomo ʻo Traverso a me kāna hui noiʻi i nā microparticles i uhi ʻia i ka peptide i loko o ka hydrogel. Ua hoʻokuʻu ʻia nā peptides i ka wā i loaʻa ai nā enzyme pili i ka mumū. Ke hoʻokuʻu ʻia, hiki ke ʻike ʻia nā peptides i ka mimi, no laila hiki i kahi urinalysis maʻalahi ke loaʻa iā lākou a makaʻala i nā kauka i ka loaʻa ʻana o ka maʻi ma ke kahua suture i loko o ke kino.

Topical infusion o ka lāʻau

No ka lawe ʻana i ka lāʻau lapaʻau, ua hoʻokomo maikaʻi nā mea noiʻi i nā mea i hoʻohana ʻia no ka mālama ʻana i ka maʻi ʻeha i loko o ka hydrogel. Hoʻopili ʻia nā antibodies monoclonal a me nā steroid i loko o nā polymers i hoʻohana ʻia e kāohi i ka nui o ka hoʻokuʻu ʻana i ka lāʻau lapaʻau, a laila lawe ʻia i loko o kahi hydrogel ma ka ʻili o ke kaula. Ua ʻōlelo ka poʻe noiʻi hiki ke hoʻohui pū ʻia nā lāʻau lapaʻau ʻē aʻe, me nā lāʻau antibiotic a i ʻole nā ​​lāʻau chemotherapy.

Hāʻawi pū i ke kumu

Ua hoʻohana ka poʻe noiʻi i nā sutures e hoʻopuka i nā pūnana pū, i hana ʻia e hōʻike i nā hōʻailona fluorescent, a ma ka ʻimi ʻana i nā cell glowing, ua ʻike lākou ua noho mau lākou ma ka ʻili o nā sutures i loko o nā kino o nā ʻiole lab no nā lā ʻehiku. Ua hiki nō i nā pūnaewele ke hana i kahi mea i kapa ʻia ʻo vascular endothelial growth factor (VEGF), ka mea e hoʻoulu ai i ka hana ʻana o nā ʻāpana koko hou e hiki ke kōkua i ka hoʻōla wikiwiki ʻana i nā wahi o ke kino.

Hoʻoulu

ʻO ka hui noiʻi i hoʻomaka mua ʻia e ka manaʻo ma hope o ka loaʻa ʻana o nā sutures e hiki ke hana maikaʻi no nā poʻe maʻi me ka maʻi o Crohn, kahi maʻi ʻeha ʻeha i hiki i nā hihia koʻikoʻi ke alakaʻi i ka wehe ʻana i nā ʻāpana o nā ʻōpū o nā maʻi. Manaʻo ka poʻe noiʻi e alakaʻi nā hopena o ka noiʻi i ka hoʻohana ʻana i nā sutures hou i nā ʻano kaʻina hana.
