Un nou instrument al inteligen\u021bei artificiale \u00eei ajut\u0103 pe oamenii de \u0219tiin\u021b\u0103 s\u0103 studieze obezitatea \u0219i modul \u00een care afecteaz\u0103 tot corpul, potrivit Euronews<\/a>.<\/p>\n

Acest \u201eatlas corporal\u201d dezv\u0103luie daune extinse dincolo de \u021besutul adipos, obezitatea afect\u00e2nd corpul la nivel celular.<\/p>\n

Studiul a fost publicat \u00een revista \u201eNature\u201d, la care au colaborat cercet\u0103tori de la Helmholtz M\u00fcnchen, Universitatea Ludwig Maximilian din M\u00fcnchen \u0219i de la institu\u021bii colaboratoare.<\/p>\n

MouseMapper permite studiul \u00eentregului corp \u00een acela\u0219i timp<\/h2>\n

Modelul de IA utilizat, numit MouseMapper, a construit un \u201eatlas\u201d 3D detaliat al \u00eentregului corp. Acesta a identificat organe, nervi \u0219i celule imune \u00een zeci de milioane de structuri simultan.<\/p>\n

P\u00e2n\u0103 acum, oamenii de \u0219tiin\u021b\u0103 puteau studia doar modific\u0103rile bolilor organ cu organ. Noul sistem permite o imagine complet\u0103 a corpului \u00eentr-o singur\u0103 analiz\u0103.<\/p>\n

Pentru dezvoltarea sistemului, cercet\u0103torii au marcat nervii \u0219i celulele imune la \u0219oareci folosind markeri fluorescen\u021bi. Ulterior, animalele au fost tratate cu tehnici de cur\u0103\u021bare a \u021besuturilor, care au f\u0103cut corpurile transparente optic. \u00cen acela\u0219i timp, au fost p\u0103strate aceste semnale fluorescente, mai arat\u0103 sursa.<\/p>\n

IA a cartografiat 31 de tipuri de organe \u0219i \u021besuturi<\/h2>\n

Microscopia special\u0103 cu folie de lumin\u0103 a produs scan\u0103ri 3D de \u00eenalt\u0103 rezolu\u021bie ale corpurilor. Apoi, inteligen\u021ba artificial\u0103 a analizat automat imaginile \u0219i a cartografiat 31 de tipuri de organe \u0219i \u021besuturi.<\/p>\n

Astfel, cercet\u0103torii au putut vedea unde apar simultan inflama\u021bia \u0219i leziunile structurale \u00een tot corpul.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 au testat sistemul pe \u0219oareci hr\u0103ni\u021bi cu o diet\u0103 bogat\u0103 \u00een gr\u0103simi. Animalele au dezvoltat obezitate \u0219i modific\u0103ri metabolice similare cu cele ale oamenilor. Rezultatele au ar\u0103tat inflama\u021bii pe scar\u0103 larg\u0103 \u0219i modific\u0103ri ale \u021besutului \u00een mai multe organe, inclusiv gr\u0103sime, ficat \u0219i mu\u0219chi.<\/p>\n

Descoperiri fascinante la nivelul sistemului nervos<\/h2>\n

Cercet\u0103torii au descoperit modific\u0103ri structurale majore la nivelul nervului trigemen, care controleaz\u0103 senza\u021bia facial\u0103. La \u0219oarecii obezi, nervul avea mai pu\u021bine ramifica\u021bii \u0219i termina\u021bii. \u00cen acest mod, s-a sugerat o pierdere a func\u021biei senzoriale normale. Testele comportamentale au confirmat c\u0103 \u0219oarecii au r\u0103spuns mai pu\u021bin la atingere \u0219i stimulare.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 au analizat apoi mostre de \u021besut uman de la persoane cu obezitate. <\/span>Ei au descoperit modific\u0103ri moleculare similare \u00een ganglionul trigemen, centrul nervos legat de senza\u021bia facial\u0103. Descoperirile<\/span> sugereaz\u0103 c\u0103 leziunile nervoase legate de obezitate observate la \u0219oareci pot ap\u0103rea \u0219i la oameni.<\/span><\/p>\n

\u201eGemenii digitali\u201d, un viitor instrument de simulare a progresiei bolilor<\/h2>\n

Platforma ar putea transforma modul \u00een care sunt studiate bolile complexe, sus\u021bin oamenii de \u0219tiin\u021b\u0103. Cu ajutorul IA, pot examina acum modul \u00een care bolile afecteaz\u0103 \u00eentregul corp \u0219i nu doar s\u0103 analizeze un organ pe r\u00e2nd.<\/p>\n

Cercet\u0103torii \u00ee\u0219i doresc s\u0103 construiasc\u0103 \u00een viitor \u201egemeni digitali\u201d ai unor organisme. Ace\u0219tia le-ar permite s\u0103 simuleze progresia bolilor \u0219i s\u0103 testeze tratamente \u00eenainte de a trece la experimente fizice. Construc\u021bia lor ar putea accelera descoperirea medicamentelor \u0219i ar reduce nevoia de experimente pe animale, mai precizeaz\u0103 sursa.<\/p>\n","protected":false},"excerpt":{"rendered":"
