The ‘Archaeological Map of Lilybaeum’
The ‘Archaeological Map of Lilybaeum’ is the result of the long-standing scientific cooperation in Marsala between Palermo and Hamburg Universities. This paper investigates the various methods of field research used to gather the necessary data for the archaeological map of ancient Lilybaeum. There will be a particular focus on the topographic survey and photogrammetric aerial survey by Remotely Piloted Aircraft System (RPAS) conducted in the years 2017–2019. The aim of the work is to highlight the impact of the results on already existing research hypotheses and the ways in which the resulting map enhances our knowledge of the ancient city of Lilybaeum.
Impact of T-cell-mediated immune response on xenogeneic heart valve transplantation: short-term success and mid-term failure.
Objectives Allogeneic frozen cryopreserved heart valves (allografts or homografts) are commonly used in clinical practice. A major obstacle for their application is the limited availability in particular for paediatrics. Allogeneic large animal studies revealed that alternative ice-free cryopreservation (IFC) results in better matrix preservation and reduced immunogenicity. The objective of this study was to evaluate xenogeneic (porcine) compared with allogeneic (ovine) IFC heart valves in a large animal study. Methods IFC xenografts and allografts were transplanted in 12 juvenile merino sheep for 1-12 weeks. Immunohistochemistry, ex vivo computed tomography scans and transforming growth fa…
