Cranial surgical approaches in the 21st Century Identified Skeletal Collection

In Forensic Anthropology, identification is comparing information from a person whose fate and whereabouts are unknown with data from a person who is present but whose identity is unknown. The rarer and more distinctive the characteristics observed during the anthropological investigation, the greater the probability of reaching an identification. Taking this into account, cranial surgeries can be considered go...

The genetic history of Portugal over the past 5.000 years

Background Recent ancient DNA studies uncovering large-scale demographic events in Iberia have presented very limited data for Portugal, a country located at the westernmost edge of continental Eurasia. Here, we present the most comprehensive collection of Portuguese ancient genome-wide data, from 67 individuals spanning 5000 years of human history, from the Neolithic to the nineteenth century. Results We ident...

The genetic history of Portugal over the past 5,000 years.

Recent ancient DNA studies uncovering large-scale demographic events in Iberia have presented very limited data for Portugal, a country located at the westernmost edge of continental Eurasia. Here, we present the most comprehensive collection of Portuguese ancient genome-wide data, from 67 individuals spanning 5000 years of human history, from the Neolithic to the nineteenth century. We identify early admixture...

Aplicação forense de marcadores genéticos de ancestralidade biogeográfica e car...

A capacidade de multiplexação da sequenciação massiva em paralelo (MPS), em simultâneo com a capacidade de análise de diversos tipos de marcadores genéticos, conduziu a genética forense a uma utilização mais frequente dos polimorfismos de nucleotído único (SNPs). Iniciaram-se, também, as análises denominadas Forensic DNA Phenotyping (FDP) que incluem a inferência da ancestralidade biogeográfica (BGA) e a inferê...

Combining anthropology and imaging to reconstruct antemortem trauma for identif...

Identification of unidentified remains involves a comparison of ante- and postmortem features using biological identifiers. Anthropological identifiers, referred to by International Criminal Police Organization (INTERPOL) as secondary identifiers, have often been judged less reliable than DNA, fingerprints and dental records (referred to as primary identifiers). However, anthropological identifiers have been pr...

Human identification by medical findings in a forensic anthropology context

This article presents a series of three complex forensic cases that posed significant challenges for identifying human remains. These include a mass dam disaster, burnt human remains, and extensively decomposed human remains. Positive identification was achieved using a shadow positioning technique with imaging comparisons of medical findings. After establishing the biological profile, medical data were evaluat...

Forensic identification in a multidisciplinary perspective focusing on big chal...

Estudo de Y-SNPs com os métodos de sequenciação de nova geração (NGS): aplicaçõ...

Na genética forense, o estudo do cromossoma Y tem um papel essencial em amostras de misturas de ADN masculino-feminino, comum em casos de agressão sexual. Além disso, através do estudo do ADN do cromossoma Y é possível determinar o número de contribuintes do sexo masculino em amostras de misturas complexas onde estão presentes múltiplos homens. A determinação das linhagens paternas do cromossoma Y, pode ser fei...

Postmortem interval estimation of human skeletonized remains through luminol ch...

Postmortem interval (PMI) estimation represents a significant challenge in the forensic sciences, particularly when dealing with human skeletal remains. A screening protocol for distinguishing possible remains of forensic interest is a crucial tool for judicial purposes. In this context, luminol chemiluminescence emerges as a promising method, with low overall costs and required time. This method is primarily u...

Luminol and the postmortem interval estimation — influence of taphonomic factors

The estimation of the postmortem interval (PMI) is one of the key challenges for forensic anthropologists. Although there are several methods referenced for this purpose, none is sufficiently effective. One of the main reasons justifying the complexity of this task is the influence of several taphonomic factors.The study of the Luminol technique has stood out as a promising method for estimating PMI, complement...
