Nj\u00eb biologe e re argjentinase, Pilar Ferrer, po punon s\u00eb bashku me nj\u00eb grup studiuesish p\u00ebr zhvillimin e nj\u00eb materiali q\u00eb mund t\u00eb ndihmoj\u00eb n\u00eb riparimin e zonave t\u00eb d\u00ebmtuara.
Hidroxheli synon t\u00eb riparoj\u00eb zemr\u00ebn pas infarktit. Materiali mund t\u00eb ndihmoj\u00eb n\u00eb rigjenerimin e muskulit t\u00eb zemr\u00ebs. Provat e para n\u00eb kafsh\u00eb jan\u00eb inkurajuese, por trajtimi mbetet ende n\u00eb faz\u00ebn eksperimentale.<\/p>\n\n\n\n
N\u00eb krye t\u00eb k\u00ebtij projekti \u00ebsht\u00eb biologja 25-vje\u00e7are Pilar Ferrer, e diplomuar n\u00eb Universitetin Favaloro dhe drejtuese ekzekutive e startup-it bioteknologjik Amnova Biotech. Ajo punon s\u00eb bashku me nj\u00eb ekip nd\u00ebrdisiplinor n\u00eb Laboratorin e Mjek\u00ebsis\u00eb Rigjeneruese Kardiovaskulare t\u00eb Institutit t\u00eb Mjek\u00ebsis\u00eb Translacionale, Transplantimit dhe Bioinxhinieris\u00eb, n\u00eb bashk\u00ebpunim me Universitetin Favaloro dhe CONICET-in, institucionin komb\u00ebtar argjentinas t\u00eb k\u00ebrkimit shkencor.<\/p>\n\n\n\n
Projekti nisi si pjes\u00eb e k\u00ebrkimit t\u00eb saj doktoral dhe m\u00eb pas u shnd\u00ebrrua n\u00eb nj\u00eb zhvillim bioteknologjik me synimin p\u00ebr t\u00eb arritur nj\u00eb dit\u00eb te pacient\u00ebt.<\/p>\n\n\n\n
Pas nj\u00eb infarkti, mungesa e furnizimit me gjak dhe oksigjen shkakton vdekjen e nj\u00eb pjese t\u00eb qelizave t\u00eb muskulit t\u00eb zemr\u00ebs. Zona e d\u00ebmtuar z\u00ebvend\u00ebsohet me ind mbresor, i cili nuk ka t\u00eb nj\u00ebjt\u00ebn aft\u00ebsi tkurr\u00ebse si muskuli i sh\u00ebndetsh\u00ebm. Kjo mund t\u00eb dob\u00ebsoj\u00eb funksionin e zemr\u00ebs dhe t\u00eb \u00e7oj\u00eb n\u00eb komplikacione afatgjata, p\u00ebrfshir\u00eb insuficienc\u00ebn kardiake.<\/p>\n\n\n\n
P\u00ebr t\u00eb p\u00ebrballuar k\u00ebt\u00eb problem, studiuesit po zhvillojn\u00eb nj\u00eb hidrogel bioaktiv, i cili injektohet drejtp\u00ebrdrejt n\u00eb zon\u00ebn e d\u00ebmtuar t\u00eb zemr\u00ebs.<\/p>\n\n\n\n
Ve\u00e7antia e tij q\u00ebndron te l\u00ebnda e par\u00eb, matrica e membran\u00ebs amniotike, nj\u00eb struktur\u00eb biologjike q\u00eb gjendet n\u00eb placent\u00eb. Studiuesit kan\u00eb shfryt\u00ebzuar vetit\u00eb e k\u00ebsaj matrice, pa p\u00ebrdorur qeliza staminale, p\u00ebr t\u00eb krijuar nj\u00eb material q\u00eb sh\u00ebrben si nj\u00eb lloj strukture mb\u00ebshtet\u00ebse p\u00ebr qelizat e sh\u00ebndetshme.<\/p>\n\n\n\n
Synimi \u00ebsht\u00eb t\u00eb krijohet nj\u00eb mjedis m\u00eb i favorsh\u00ebm p\u00ebr riparimin e indit, shumimin e qelizave dhe formimin e en\u00ebve t\u00eb reja t\u00eb gjakut, duke ndihmuar n\u00eb ruajtjen e funksionit t\u00eb zemr\u00ebs.<\/p>\n\n\n\n
Sipas Pilar Ferrer, zhvillimi ka kaluar faz\u00ebn e par\u00eb t\u00eb testimeve laboratorike me qeliza dhe ka avancuar n\u00eb studimet paraklinike te kafsh\u00ebt. N\u00eb nj\u00eb intervist\u00eb p\u00ebr median argjentinase LA NACION, ajo b\u00ebri t\u00eb ditur se materiali \u00ebsht\u00eb testuar edhe te delet, ku jan\u00eb v\u00ebrejtur rezultate inkurajuese gjat\u00eb vler\u00ebsimeve 28-ditore.<\/p>\n\n\n\n
Megjithat\u00eb, k\u00ebto rezultate nuk p\u00ebrb\u00ebjn\u00eb ende prov\u00eb se trajtimi \u00ebsht\u00eb i sigurt dhe efektiv p\u00ebr njer\u00ebzit.<\/p>\n\n\n\n
Sipas planit t\u00eb prezantuar nga Ferrer, ekipi synon t\u00eb nis\u00eb procesin e nevojsh\u00ebm rregullator p\u00ebrpara se t\u00eb kaloj\u00eb n\u00eb studimet klinike. Ajo ka p\u00ebrmendur si objektiv nisjen e tyre pas rreth dy vitesh, n\u00ebse plot\u00ebsohen kushtet shkencore, financiare dhe rregullatore.<\/p>\n\n\n\n
P\u00ebr momentin, hidrogel-i nuk \u00ebsht\u00eb i disponuesh\u00ebm n\u00eb spitale dhe nuk mund t\u00eb konsiderohet nj\u00eb kur\u00eb e provuar p\u00ebr d\u00ebmtimet e zemr\u00ebs apo nj\u00eb alternativ\u00eb ndaj transplantit kardiak.<\/p>\n\n\n\n
N\u00ebse k\u00ebrkimet e m\u00ebtejshme konfirmojn\u00eb sigurin\u00eb dhe efektivitetin e tij, ky material mund t\u00eb p\u00ebrfaq\u00ebsoj\u00eb nj\u00eb hap t\u00eb r\u00ebnd\u00ebsish\u00ebm n\u00eb mjek\u00ebsin\u00eb rigjeneruese: jo thjesht trajtimin e pasojave t\u00eb nj\u00eb infarkti, por mund\u00ebsin\u00eb p\u00ebr t\u00eb ndihmuar zemr\u00ebn t\u00eb riparoj\u00eb nj\u00eb pjes\u00eb t\u00eb d\u00ebmit t\u00eb shkaktuar.<\/p>\n\n\n\n
