Virtopsy shows a high status funerary treatment in an early 18th Dynasty non-royal individual.

This work presents the multidisciplinary investigation of the head of Nebiri (Museo Egizio, Turin S_5109), Chief of Stables, a high status elite person from the 18th Dynasty involving MDCT, 3D brain surface and facial reconstructions accompanied by a consideration of previously presented chemical analysis of the embalming materials found in fragments of bandages used on the head and viscera (lung) found in one of the four canopic jars. Comparison of the techniques used for the cosmetic treatment of Nebiri with those used in other elite and high status non-royal persons confirms the validity of the use of the term "high status elite" in the case of Nebiri. This case highlights the importance of using modern forensic techniques both to enhance new technologies of retrospective diagnosis on altered human remains and to increase knowledge of past populations.

Forensic Analysis Reveals Acute Decompensation of Chronic Heart Failure in a 3500-Year-Old Egyptian Dignitary.

Naturally preserved and embalmed bodies from archeological contexts represent a powerful source of information for forensic investigators. They allow one to ascertain pathology, cause of death, to enhance diagnostic methodology, and to improve the analysis of altered remains. We investigated the complete head and lung remnants of a 3,500-year-old Egyptian dignitary by radiological, microscopic, and genetic approaches. The individual, a middle-aged male, suffered from severe periodontitis, mild atherosclerosis, and experienced cardiogenic pulmonary insufficiency with recurrent mini-bleeds and pulmonary edema. Histology and ancient DNA analyses excluded the presence of Mycobacterium tuberculosis or of any other pathogenic species. Based on our collection of evidence, we propose that acute decompensation complicating chronic cardiac insufficiency was the likely cause of death. The underlying causes for this failure remain unknown although chronic hypertension appears to be the most likely candidate. Our finding represents the earliest reported case of chronic heart failure in ancient mummies.

A pre-Hispanic head.

This report on a male head revealed biologic rhythms, as gleaned from hydrogen isotope ratios in hair, consistent with a South-American origin and Atomic Mass Spectrometry radiocarbon dating (AMS) compatible with the last pre-Hispanic period (1418-1491 AD, 95.4% probability). Biopsies showed exceptionally well-preserved tissues. The hair contained high levels of toxic elements (lead, arsenic and mercury) incompatible with life. There was no evidence for lead deposition in bone consistent with post-mortem accumulation of this toxic element in the hair. We propose that the high content of metals in hair was the result of metabolic activity of bacteria leading to metal complexation in extra cellular polymeric substances (EPS). This is a recognized protective mechanism for bacteria that thrive in toxic environments. This mechanism may account for the tissues preservation and gives a hint at soil composition where the head was presumably buried. Our results have implications for forensic toxicology which has, hitherto, relied on hair analyses as one means to reconstruct pre-mortem metabolism and for detecting toxic elements accumulated during life. Our finding also has implications for other archaeological specimens where similar circumstances may distort the results of toxicological studies.
