PUCRS research resonates internationally by revealing intact cells in mummy

Study developed by the Afro-Egyptian Identity Study Group at the School of Humanities was published by the European Association for Osseointegration

Researchers at PUCRS discovered, from tissue processing tests, that the head of a mummy from 2,495 to 2,787 years old contained cells still intact . Iret-Neferet , as it was baptized, arrived in Brazil in the 1950s, in Cerro Largo. The work was presented at an event recent in Berlin, Germany, promoted by the European Association of Osseointegration . The publication is international reference and has maximum rating by Coordination for the Improvement of Higher Education Personnel (Capes) < span data-contrast = "auto">.

The study was carried out p sibling links Éder Huttner < span data-contrast = "auto">, surgeon buccomaxillofacial and gerontologist , and Édison Hut tner < / span>, teacher d o Graduate Program in History And researcher . Both act in the Afro-Egyptian Identity Study Group of School of Humanities da PUCRS and had the participation of the specialist in Periodontics Bruno Candeias in scientific production.

The newly made histology allowed the visualization of intact red cells morphologically within a blood vessel in the head, as well as the structure of the bone tissues of the masseter's jaw and muscle, ”he explains.

The results revealed the effectiveness and technological quality of the time in the mummification process and allows further studies on the Genome and Proteome to be carried out.

Édison says that in addition to a historical importance, the discovery also impacts in understanding about health da humanity . “< / span> N naturally this research will serve as a basis for other works , makes nd a reference in Brazil, na America Latin a and until worldwide , mainly and nte when it comes to preservation ee study d human health . < / span>
