Zaka makumi atatu zapitazo, akatswiri ofukula za m’mabwinja anafukula manda a mwamuna wina wapamwamba wazaka 40-50 wochokera ku chikhalidwe cha ku Sicán ku Peru, chitaganya chimene chinalipo Ainka asanakhaleko. Chigoba cha bamboyo chokhala pansi, chopendekeka chinapakidwa utoto wofiira kwambiri, monganso chigoba chagolide chomwe chinaphimba chigaza chake chobisika. Tsopano, ochita lipoti mu ACS 'Journal of Proteome Research apenda utoto, apeza kuti, kuwonjezera pa mtundu wofiira, uli ndi magazi aumunthu ndi mapuloteni a mazira a mbalame.
Ku Sicán kunali chikhalidwe chodziwika bwino chomwe chinalipo kuyambira zaka za m'ma 14 mpaka 900 m'mphepete mwa nyanja kumpoto kwa dziko la Peru lamakono. Munthawi ya Middle Sicán Period (pafupifupi 1,100-XNUMX AD), akatswiri opanga zitsulo amapanga zinthu zonyezimira zagolide, zambiri zomwe zidakwiriridwa m'manda a anthu osankhika.
Kumayambiriro kwa zaka za m’ma 1990, gulu la akatswiri ofukula zinthu zakale ndi osunga zinthu zakale motsogozedwa ndi Izumi Shimada linafukula manda mmene mafupa a munthu wapamwamba wokhala pansi anali atapakidwa utoto wofiira ndipo anaikidwa mozondoka chapakati pa chipindacho. Mafupa a atsikana aŵiri anaikidwa pafupi ndi kubeleka ndi kuyamwitsa, ndipo mafupa a ana awiri ogwada anaikidwa pamalo okwera.
Pakati pa zinthu zambiri zagolide zomwe zinapezeka m’mandamo panali chigoba chagolide chopaka utoto wofiira, chimene chinaphimba nkhope ya chigaza chodzipatula cha munthuyo. Panthawiyo, asayansi adazindikira kuti utoto wofiira mu utotowo ndi cinnabar, koma Luciana de Costa Carvalho, James McCullagh ndi anzawo adadabwa ndi zomwe anthu a Sicán adagwiritsa ntchito posakaniza utoto ngati chinthu chomangirira, chomwe chidasunga utoto wosanjikiza ku zitsulo pamwamba chigoba kwa zaka 1,000.
Kuti adziwe, ofufuzawo adasanthula kachitsanzo kakang'ono ka utoto wofiira wa chigobacho. Fourier transform-infrared spectroscopy inawulula kuti chitsanzocho chinali ndi mapuloteni, motero gululo lidachita kafukufuku wa proteinomic pogwiritsa ntchito tandem mass spectrometry. Anazindikira mapuloteni asanu ndi limodzi ochokera m'magazi a munthu mu utoto wofiira, kuphatikizapo serum albumin ndi immunoglobulin G (mtundu wa seramu antibody). Mapuloteni ena, monga ovalbumin, adachokera ku dzira loyera. Chifukwa chakuti mapuloteniwo anali owonongeka kwambiri, ofufuzawo sanathe kudziwa mtundu weniweni wa dzira la mbalame lomwe linagwiritsidwa ntchito popanga utoto, koma yemwe ayenera kukhala nawo ndi bakha waku Muscovy.
Kuzindikirika kwa mapuloteni a mwazi wa munthu kumachirikiza lingaliro lakuti dongosolo la mafupa a mafupa linali logwirizana ndi “kubadwanso” kofunidwa kwa mtsogoleri wakufa wa Sicán, ndi utoto wokhala ndi mwazi umene unapaka mafupa a mwamunayo ndi chigoba cha kumaso mothekera kusonyeza “mphamvu ya moyo” yake. ” ofufuza akutero.
Nkhaniyi idasindikizidwa koyamba pa American Chemical Society. Werengani nkhani yoyambirira.
