Per aix\u00f2 combina experiments amb models matem\u00e0tics per explicar com les c\u00e8l\u00b7lules s&#8217;organitzen als teixits. Ell explica que \u201cabans de la quarantena estava estudiant la fusi\u00f3 d&#8217;agregats de<a href=\"https:\/\/ellipse.prbb.org\/ca\/tag\/cel%c2%b7lules-mare\/\" target=\"_blank\" rel=\"noreferrer noopener\"> c\u00e8l\u00b7lules mare<\/a> embrion\u00e0ries, per\u00f2 nom\u00e9s veia una <strong>fusi\u00f3 parcial<\/strong>. M\u00e9s tard vaig descobrir que aquest proc\u00e9s es coneix com a coalesc\u00e8ncia detinguda i \u00e9s un fenomen com\u00fa en la f\u00edsica de la mat\u00e8ria tova\u201d. Per\u00f2 els models que es feien servir comunament per explicar la fusi\u00f3 d&#8217;agregats cel\u00b7lulars no contemplaven la possibilitat d&#8217;aquest fenomen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aprofitant el <a rel=\"noreferrer noopener\" href=\"https:\/\/ellipse.prbb.org\/ca\/dos-projectes-per-estudiar-limpacte-de-la-covid-19-en-la-salut-mental\/\" target=\"_blank\">confinament <\/a>i que no podia fer experiments, Oriola es va dedicar a refer c\u00e0lculs i models matem\u00e0tics. Va observar que els models matem\u00e0tics que feien servir no tenien en compte les <strong>caracter\u00edstiques viscoel\u00e0stiques dels teixits biol\u00f2gics<\/strong>, sin\u00f3 que els descrivien com a fluids purament viscosos. Per aix\u00f2, Oriola va <strong>proposar un nou model<\/strong> que considera l&#8217;elasticitat com a propietat dels teixits. I, aquest s\u00ed, pot explicar els resultats experimentals observats.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aix\u00ed, <strong>aquest nou model proporciona un<\/strong> <strong>m\u00e8tode r\u00e0pid i barat per estudiar les propietats mec\u00e0niques dels teixits<\/strong>. Per\u00f2, a m\u00e9s, com diu Oriola \u201caquest model pot tenir implicacions molt m\u00e9s enll\u00e0 de la biologia, ja que podria arribar a fer-se servir per caracteritzar les propietats materials de les microemulsions, per exemple\u201d.<\/p>\n\n\n\n<div style=\"height:43px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-text-color has-cyan-bluish-gray-color wp-block-paragraph\">Vols veure la teva foto aqu\u00ed?
