Multiphoton Absorption of Myoglobin Nitric-Oxide complex: Relaxation by D-NEMD of a Stationary State
2012
ABSTRACT: The photodissociation and geminate recombination of nitric oxide in myoglobin, under continuous illumination, is modeled computationally. The relaxation of the photon energy into the protein matrix is also considered in a single simulation scheme that mimics a complete experimental setup. The dynamic approach to non-equilibrium molecular dynamics is used, starting from a steady state, to compute its relaxation to equilibrium. Simulations are conducted for the native form of sperm whale myoglobin and for two other mutants, V68W and L29F, illustrating a fair diversity of spatial and temporal geminate recombination processes. Energy flow to the heme and immediate protein environment …
Proteins in Amorphous Saccharides: Structural and Dynamical Insights on Bioprotection
2011
We report on experimental and simulative insights on saccharide-based bioprotection, obtained through the study of proteins embedded in amorphous saccharide matrices. The data presented come from a complementary set of techniques (FTIR, MD simulations and SAXS), which provides a description of the bioprotection mechanism from the atomistic to the macroscopic level. The results concur to draw a picture in which bioprotection by saccharides can be explained in terms of a tight anchorage of the protein surface to a stiff matrix, via extended hydrogen-bond networks, whose properties are defined by all its components, and are strongly dependent on the water content. In particular, they show how …
A Classification of Palermo Historical Centre Heritage based on the local seismic response
2009
A very high density of monumental heritage falls within Palermo Historical Centre, an area characterized by high variability of near surface geology and soil physical-mechanical properties on a very short distance scale, even few meters. So, neighboring heritage elements can have a totally different hazard exposition. Within a project regarding Palermo area (Project 7T7, Cluster 29, funded by Ministero dell’Università e della Ricerca, Italy) a very reliable high density stratigraphic-geotechnical dataset has been assembled, by means of a careful data reviewing process. This dataset has been stored in a Geographic Information System (GIS) application, named City-GIS, having all GIS functions…
Comunicazione e costruzione di realtà. Il trattamento del Mezzogiorno d'Italia nel cinema
2014
Nel volume si esamina lo spazio riservato al Mezzogiorno d'Italia nel cinema neorealista e d'inchiesta. Il tutto inserito nel quadro generale della Narratologia francese e di Comunicazione e costruzione di realtà. In the book it's studied the space reserved to South Italy in the neorealistic and italian cinema of inquiry. All is inserted in a general context of french Narratology & Communication and construction of reality
Setting the basis for the study of intermediate conformers of human neuroserpin by Double Electron Electron Resonance
2012
The Double Electron Electron Resonance (DEER) is an innovative technique that allows to measure the distance distribution between two spin labels within a range of 2-8 nm. This technique does not require crystalline samples, thus it is possible to determine the position of two different spin labelled domains of intrinsically flexible macromolecular systems. Our idea is to determinate the structural details of the intermediate conformers of human neuroserpin (hNS) by DEER. hNS is a protein that in the native state is folded in a metastable conformation. In particular conditions, hNS can either adopt a more stable conformation with the reactive centre loop (RCL) inserted into a β-sheet (laten…

New insight on metal finds of the Punic Ship of Lilibeum
2020
In this paper, the investigation of some finds (two nails, a head and a long shaft nail, and a fragment of Lead sheathing) belonging to the wreck of the Punic ship and exhibited at Museo Archeologico Regionale Lilibeo (Trapani, Italy), is reported. The X-ray Fluorescence Spectroscopy (XRF) allowed us to identify the elements constituting them making some discussion deductions about their composition and degradation occurred.
