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…

The EDNAP mitochondrial DNA population database (EMPOP) collaborative exercises: organisation, results and perspectives.

2003

This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to id…

Cryptic species within the freshwater copepod genus Hemidiaptomus (calanoida, diaptomidae).

2009

The copepod genus Hemidiaptomus is composed by about 17 large-bodied species inhabiting the freshwater temporary water bodies of the whole Palaearctic region. It currently comprises three subgenera, which are mostly parapatric and present only limited co-occurrence areas. There is no consensus on the taxonomical arrangement of the entire group, and to date no molecular studies have been carried out to test it. Accordingly, a thorough revision of the entire genus using a combined morphological and molecular approach is strongly advisable. We have thus decided to investigate the pattern of morphological and molecular diversity of three species of the genus Hemidiaptomus belonging to the three…

MITOCONDRIAL DNA VARIATION IN ITALIAN BOS PRIMIGENIUS: NEW CLUES INTO THE CATTLE DOMESTICATION PROCESS.

Cancer as a “Mitochondriopathy”.

2007

Mitochondria are subcellular organelles, whose well-known function is to produce adenosine triphosphate (ATP) through oxidative phosphorylation (OXPHOS). Alterations in respiratory activity and mtDNA appear to be a general feature of malignant cells. The presence of mtDNA mutations has been reported in various cancer cells, and the abundance of mtDNA damage is consistent with the intrinsic susceptibility to constitutive oxidative stress. Research about the functional aspects of mtDNA mutations in cancer development and therapeutic response is likely to be fruitful and to have significant clinical and prognostic impact. Although many studies to date have been focused on the identification an…

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…

On the origin and systematics of the northern African wood mouse (<i>Apodemus sylvaticus</i>) populations: a comparative study of mtDNA r…

2001

Conflicting hypotheses have been formulated regarding the origin of wood mouse (Apodemus sylvaticus) populations in northern Africa. In this study, the mtDNA restriction patterns of mice (n = 28) collected in Tunisia and Morocco are compared with those of representatives from southern Europe (n = 102). The neighbour-joining tree confirms the existence of the three lineages previously found in the Mediterranean area: western, Tyrrhenian–Balkan, and Sicilian. The western group is isolated from the two others, with bootstrap values of 89 and 95%. Northern African patterns are included in the western group. Their variability is low, the same pattern being shared by five Tunisian and all Morocca…
