Cocina cave revisited: Bayesian radiocarbon chronology for the last hunter-gatherers and first farmers in Eastern Iberia
2018
Abstract Recent excavations and radiocarbon work conducted at Cocina Cave (Valencia region, Eastern Iberia) provide new insights into the transition from foraging to farming in the eastern Iberian Peninsula between 8000 and 7300 cal yrs. BP. Cocina cave was discovered in 1940 and excavated by L. Pericot from 1941 to 1945. J. Fortea continued excavations in the 70s. Despite early international recognition and great promise of significance, the materials recovered from these excavations have only been partially analyzed and published. A new project started in 2012 is focused on these cave deposits with the main goal of understanding the occupation sequence during the neolithization process in…
Neotropical primate evolution and phylogenetic reconstruction using chromosomal data
2017
Platyrrhini are a group of Neotropical primates living in central and south America, and have been extensively studied through morphological and molecular data in order to shed light on their phylogeny and evolution. Agreement on the main clades of Neotropical primates has been reached using different approaches, but many phylogenetic nodes remain under discussion. Contrasting hypotheses have been proposed, presumably due to different markers and the presence of polymorphisms in the features considered; furthermore, neither Neotropical primate biodiversity nor their taxonomy are entirely known. In our perspective, a cytogenetic approach can help by making an important contribution to the ev…

Ad laudem Divini nominis et honorem gloriosissimae Dei Genetricis et semper Virginis Mariae. L’abbazia di Santa Maria di Altofonte
2019
Inediti documenti fanno in parte riemergere l’antico splendore dell’abbazia di Santa Maria di Altofonte, fondata da Federico III e retta dal XV secolo da abati commendatari appartenenti a nobili famiglie, come Ascanio Colonna, Scipione Borghese e Francesco Maria Medici. Dell’esiguo patrimonio artistico rimasto fa parte la coppia di reliquiari di argentiere messinese del 1727 ascritta alla committenza dell’abate Bartolotta. New documents partly re-emerge the ancient splendour of the abbey of Santa Maria di Altofonte, founded by Frederick III and ruled since the 15th century by commendatory abbots belonging to noble families, such as Ascanio Colonna, Scipione Borghese and Francesco Maria Medi…
Diffuse Type of Giant-Cell Tumor of Tendon Sheath: An Ultrastructural Study of Two Cases With Cytogenetic Support
2002
Two cases of the diffuse type of giant-cell tumor of the tendon sheath (GCTTS) are described. Both tumors arose in the vicinity of large joints of the lower extremity, showing similar clinical and radiological features. Histologically, a proliferation of polygonal mononuclear cells was seen, together with osteoclastlike giant cells, foam cells, and siderophages. The tumors were poorly delineated, displaying an infiltrative pattern into the neighboring soft tissues. Immunohistochemically, strong expression of vimentin, neuron-specific enolase, A1-antitrypsin, and CD68 was found in both mono- and multinucleated tumor cells. At the ultrastructural level, mononuclear cells revealed a diverse mo…
Chromosome painting for cytogenetic monitoring of occupationally exposed and non-exposed groups of human individuals.
2001
The suitability of a three-color fluorescence in situ suppression hybridization technique was examined for monitoring five different groups of individuals: 30 occupied in radiology, 26 occupied in nuclear medicine or radiation physics, 32 patients with breast cancer, 26 occupied with military waste disposal, all presumably exposed to low doses of radiation or chemical mutagens and a non-exposed control group (N=29). The average frequency of breaks constituting the various aberrations did not significantly differ between the groups of medical radiation appliers and the control group. However, breast tumor patients and military waste disposers, as groups, showed a higher aberration rate than …
L’immagine di Agatocle e l’arte dell’età di Agatocle
2013
La tradizione letteraria, spesso ostile, ci restituisce in termini assai nitidi un’immagine di Agatocle del tutto in linea con le tendenze eminenti nell’arte aulica del Primo Ellenismo. Il Siracusano risulta aver sfruttato con abilità e perspicacia i clichés dell’ideologia regale affermatasi tra i Diadochi e gli Epigoni, nei regni originatisi dalla divisione dell’impero di Alessandro, fondata sull’esaltazione delle virtù militari eccezionali e del carisma del re (degno emulo del grande Macedone), e del suo stile di vita “straordinario”, cui le grandi feste e i banchetti danno occasione di ostentare magnificenza e generosità, definendo altresì le nuove gerarchie sociali. Da un lato quindi il…
Multi-analytical study of the medieval wall paintings from the rupestrian church Grotta del Crocifisso at Lentini (eastern Sicily): new evidence of t…
2022
AbstractThis study presents the results of the examination and characterisation of the wall paintings that decorate the rupestrian church named Grotta del Crocifisso, which is located in the territory of Lentini (eastern Sicily, few tens of kilometres from Catania and Syracuse). The earliest mural paintings in the church date back to the twelfth century AD. A multi-analytical approach was adopted for the characterisation of stone materials, secondary degradation products, and pigments. For this purpose, the following techniques were used: reflected light microscopy (RLM), polarised light microscopy on thin sections (PLM), X-ray powder diffraction (XRPD), mercury intrusion porosimetry (MIP),…
Consolidation and protection by nanolime: recent advances for the conservation of the graffiti, Carceri dello Steri Palermo and of the 18th century l…
2014
Abstract Nanolime dispersed in 2-propanol was extensively used for the consolidation of wall paintings. The knowledge of the advances of this methodology dealing with all the possible effects associated with the nanolime new material in conservation is fundamental to assess and improve the technique. In this paper, four different dispersions of Ca(OH) 2 nanoparticles were characterised by Small Angle X-rays Scattering technique (SAXS) and Transmission Electron Microscopy (TEM) in order to achieve information on size, shape, polydispersity, agglomeration, and crystal structure (by SAED patterns) of the particles. Once characterised, the dispersions were tested in two different case studies, …
Spectroscopic analysis used to uncover the original paint colour of the Helsinki Government Palace tower clock faces
2016
The paint stratigraphy of the two clock faces from the tower clock of the Government Palace in Helsinki (Finland) was analysed in order to determine their original colour before restoration works. Paint cross-section samples from both clock faces were analysed by confocal Raman microscopy and scanning electron microscopy coupled to an energy dispersive X-ray spectrometer (SEM-EDS). The results revealed the complex superimposition of paint layers applied over the original black colour. FTIR/ATR analyses proved that the original paint was prepared with linseed oil-resin media. Most likely not all of the different layer colours were visible. Some of the layers were likely to have been a primer…
