O echip\u0103 condus\u0103 de speciali\u0219ti de la Universitatea din Edinburgh a produs vase de s\u00e2nge imprimate 3D, care imit\u0103 \u00eendeaproape propriet\u0103\u021bile venelor umane. Exper\u021bii sper\u0103 c\u0103 vasele sintetice de s\u00e2nge ar putea \u00eembun\u0103t\u0103\u021bi rezultatele opera\u021biilor de bypass cardiac.<\/p>\n\n\n\n
Laboratorul Facult\u0103\u021bii de Inginerie a Universit\u0103\u021bii din Edinburgh a produs un vas de s\u00e2nge sintetic dintr-un gel pe baz\u0103 de ap\u0103, folosind o imprimant\u0103 3D cu un ax rotativ integrat. Apoi l-au \u00eent\u0103rit printr-un proces numit electrospinning, care utilizeaz\u0103 tensiuni ridicate pentru a extrage nanofibre sub\u021biri, acoperind tubul cu molecule de poliester biodegradabile.<\/p>\n\n\n\n
\nEchipa a declarat c\u0103 tuburile sintetice flexibile, care sunt la fel de puternice ca vasele de s\u00e2nge naturale \u0219i u\u0219or de integrat \u00een organism, ar putea \u00eenlocui venele umane \u0219i sintetice care sunt utilizate \u00een prezent pentru redirec\u021bionarea fluxului sanguin \u00een opera\u021biile de bypass cardiac.<\/p>\n<\/blockquote>\n\n\n\n
Potrivit cercet\u0103torilor, acest lucru ar putea limita cicatricile, durerea \u0219i riscul de infec\u021bie asociate cu \u00eendep\u0103rtarea venelor umane \u00een opera\u021biile de bypass cardiac.<\/p>\n\n\n\n
Echipa spune c\u0103 vasele sintetice care pot avea un diametru cuprins \u00eentre 1 mm \u0219i 40 mm, ar putea reduce e\u0219ecul grefelor sintetice mici, care pot fi greu de integrat \u00een organism.<\/p>\n\n\n\n
\u201eAceast\u0103 tehnic\u0103 hibrid\u0103 deschide posibilit\u0103\u021bi noi \u0219i interesante pentru fabricarea construc\u021biilor tubulare \u00een ingineria \u021besuturilor\u201d, a explicat, autorul principal, dr. Faraz Fazal.<\/p>\n\n\n\n
\n\u201eCu sprijin \u0219i colaborare continue, viziunea unor op\u021biuni de tratament \u00eembun\u0103t\u0103\u021bite pentru pacien\u021bii cu boli cardiovasculare ar putea deveni realitate\u201d, a declarat cercet\u0103torul Norbert Radacsi.<\/p>\n<\/blockquote>\n\n\n\n
\u201eRezultatele cercet\u0103rii noastre abordeaz\u0103 o provocare de lung\u0103 durat\u0103 \u00een domeniul ingineriei \u021besuturilor vasculare \u2013 producerea unui vas sintetic care are propriet\u0103\u021bi biomecanice similare cu cele ale venelor umane\u201d, a precizat sursa citat\u0103.<\/p>\n\n\n\n
Urm\u0103toarea etap\u0103 a studiului va implica cercetarea utiliz\u0103rii vaselor de s\u00e2nge la animale, \u00een colaborare cu Institutul Roslin al universit\u0103\u021bii, urmat\u0103 apoi de teste la om.<\/p>\n\n\n\n
Cercetarea, publicat\u0103 \u00een revista Advanced Materials Technologies, a fost realizat\u0103 \u00een colaborare cu Universitatea Heriot-Watt.<\/p>\n\n\n\n
