Shedding Light on the Dark Ages: Sketching Potential Trade Relationships in Early Medieval Romania through Mitochondrial DNA Analysis of Sheep Remains

2021

Southeast Europe has played an important role in shaping the genetic diversity of sheep due to its proximity to the Danubian route of transport from the Near East into Europe, as well as its possible role as a post-domestication migration network and long tradition of sheep breeding. The history of Romania and, in particular, the historical province of Dobruja, located on the shore of the Black Sea, has been influenced by its geographical position at the intersection between the great powers of the Near East and mainland Europe, with the Middle Ages being an especially animated time in terms of trade, migration, and conflict. In this study, we analyzed the mitochondrial control region of fi…

Poisoning histories in the Italian renaissance: The case of Pico Della Mirandola and Angelo Poliziano.

2018

Giovanni Pico della Mirandola and Angelo Poliziano were two of the most important humanists of the Italian Renaissance. They died suddenly in 1494 and their deaths have been for centuries a subject of debate. The exhumation of their remains offered the opportunity to study the cause of their death through a multidisciplinary research project. Anthropological analyses, together with documentary evidences, radiocarbon dating and ancient DNA analysis supported the identification of the remains attributed to Pico. Macroscopic examination did not reveal paleopathological lesions or signs related to syphilis. Heavy metals analysis, carried out on bones and mummified tissues, showed that in Pico's…

Environment and excavation: Pre-lab impacts on ancient DNA analyses

2008

Ancient DNA (aDNA) analyses enjoy an increasing role in palaeontological, archaeological and archaeozoological research. The limiting factor for aDNA studies is the degree of DNA preservation. Our study on 291 prehistoric cattle remains from Europe, the Near East and North Africa revealed that DNA preservation is mainly influenced by geographic and climatic conditions. Especially in hot climates, the preservation of sample material is generally low. We observed that these specimens are prone to further degradation and contamination during and after excavation. We give a description of the main caveats and a short guideline for adequate sample handling in order to facilitate the cooperation …

The Lady from Basel's Barfüsserkirche - Molecular confirmation of the Mummy's identity through mitochondrial DNA of living relatives spanning 22 gene…

2021

Abstract The identity of the mummified Lady from the Barfusser Church in Basel, Switzerland has been unsolved for decades, despite the prominent location of the burial place in front of the choir screen. A recent multidisciplinary research approach came up with a possible candidate, Anna Catharina Bischoff who died in Basel in 1787 with an age of 69 years (1719–1787). To verify the identity of the mummy, genealogists of the Citizen Science Basel discovered three living individuals of the maternal lineage of two different family branches, separated from Anna Catharina Bischoff by up to 22 generations. In this study we compare the ancient mitochondrial DNA of the mummy recovered from a premol…

ABO genotyping by PCR-RFLP and cloning and sequencing

2005

A refined PCR-RFLP based method was established to genotype ABO blood groups. The main objective of this study was to make the techniques also suitable for working with degraded DNA. Specific primer design was carried out to choose fragments shorter than 200 bp as necessary in forensic and archaeological applications. Four fragments of exon 6 and 7 of the ABO gene were amplified and digested by in total 7 restriction endonucleases. Particular attention was paid to the base changes at nucleotide positions 261(delG), 297, 526, 703, 721, 771, 796 and 1060(delC) in order to distinguish the six common alleles A101, A201, B, O01, O02 and O03. Furthermore, this method also enables determination of…

Microscopic findings and soil genetic “indicators” in support of pedoarchaeological studies

2015

Archaeologists use historical artefacts and archaeological records to reconstruct the communities that produced them and the environment in which they lived. Soil protects our buried or damaged heritage of archaeological and historic remains from depletion, damage, and any disturbance. Here are presented some preliminary results obtained in the framework of the FP7 Project "MEditerranean MOntainous LAndscapes: an historical approach to cultural Heritage based on traditional agrosystems (MEMOLA)" where ancient soils horizons are themselves archaeological records. In order to implement the MEMOLA archaeological study and to identify soil genetic "indicators", two integrated approaches were us…

Museum primatological collections: a valuable source of ancient DNA

Ancient DNA polymorphisms analysis to investigate scrapie susceptibility in Sicilian sheep remains from medieval archaeological sites

2014

Encephalopathy in sheep was at first described in Ireland in 1732 and was called “scrapie“ because the animals tend to tear their hair. Historically it seems to be the result of an incestuous union as breeding practice in old farms. In Sicily the animal bones found in association with the human skeletal remains from the tombs or city-sites, comprised a broad range of domestic. Usually, species included in the collected bones are domestic animals commonly eaten as sheep or goats, cattle, pigs, chickens and a small partridge. In this contest, the assemblage and the species identification is often difficult. Based on DNA barcoding, all the investigated bones were confirmed as belonging to the …

Taxidermal Preparations of an Extinct Sicilian Wolf Population (Canis lupus Linnaeus, 1758): Biological Studies and Restoration

2022

In last decades, biotechnologies have enabled a deep development of knowledge in all fields of life sciences, allowing the collection of a wide range of data. Furthermore, the relationship between scientific investigations and conservation actions of cultural heritage is increasingly consolidated and now it is one of the peculiar points both for sustainable restoration and use of the cultural asset, also evaluating the cultural assets as source of biological information. In this study, Sicilian wolf (Canis lupus) specimens conserved in Sicilian Natural Museums, become a source of biological information on Sicilian biodiversity, establishing specific conservative protocol developed cooperati…

Museomics Provides Insights into Conservation and Education:The Instance of an African Lion Specimen from the Museum of Zoology “Pietro Doderlein”

2023

Innovative technological approaches are crucial to enhance naturalistic museum collections and develop information repositories of relevant interest to science, such as threatened animal taxa. In this context, museomics is an emerging discipline that provides a novel approach to the enhancement and exploitation of these collections. In the present study, the discovery of a neglected lion skeleton in the Museum of Zoology “Pietro Doderlein” of the University of Palermo (Italy) offered the opportunity to undertake a multidisciplinary project. The aims of the study consisted of the following: (i) adding useful information for museographic strategies, (ii) obtaining a new genetic data repositor…
