Molecular Dynamics simulation of sucrose coated and trehalose coated carboxy-myoglobin
No full textWe performed a room temperature
molecular dynamics (MD) simulation on a system
containing 1 carboxy-myoglobin (MbCO) molecule
in a sucrose–water matrix of identical composition
(89% [sucrose/(sucrose water)] w/w) as for a previous
trehalose–water–MbCO simulation (Cottone et
al., Biophys J 2001;80:931–938). Results show that, as
for trehalose, the amplitude of protein atomic meansquare
fluctuations, on the nanosecond timescale, is
reduced with respect to aqueous solutions also in
sucrose. A detailed comparison as a function of
residue number evidences mobility differences along
the protein backbone, which can be related to a
different efficacy in bioprotection. Different heme
pocket structures are observed in the 2 systems. The
joint distribution of the magnitude of the electric
field at the CO oxygen atom and of the angle between
the field and the CO unit vector shows a
secondary maximum in sucrose, absent in trehalose.
This can explain the CO stretching band profile (A
substates distribution) differences evidenced by infrared
spectroscopy in sucrose- and trehalose-coated
MbCO(Giuffrida et al., J Phys ChemB2004;108:15415–
15421), and in particular the appearance of a further
substate in sucrose. Analysis of hydrogen bonds at the
protein–solvent interface shows that the fraction of
water molecules shared between the protein and the
sugar is lower in sucrose than in trehalose, in spite of
a larger number of water molecules bound to the
protein in the former system, thus indicating a lower
protein–matrix coupling, as recently observed by Fourier
transform infrared (FTIR) experiments (Giuffrida
et al., J Phys Chem B 2004;108:15415–15421)
La Sicilia del '600. Nuove linee di ricerca.
No full textI tre saggi che compongono questo libro si propongono di offrire approcci nuovi alla storia della Sicilia, analizzandola in un periodo di crisi ma proprio per questo ricco di trasformazioni, quale quello dei decenni centrali del ’600: la politica fiscale e finanziaria (Antonino Giuffrida), l’uso del patronage ecclesiastico (Fabrizio D’Avenia), la gestione delle rivolta del 1647 (Daniele Palermo). Si tratta di tre aspetti, tra loro correlati, del particolare rapporto tra la corte di Madrid e le istituzioni del Regno di Sicilia, ma che risentono e influenzano allo stesso tempo le dinamiche delle relazioni con le altre province del più ampio “sistema imperiale” spagnolo

A heuristic approach to author name disambiguation in bibliometrics databases for large-scale research assessments
No full textNational exercises for the evaluation of research activity by universities are becoming regular practice in ever more countries. These exercises have mainly been conducted through the application of peer-review methods. Bibliometrics has not been able to offer a valid large-scale alternative because of almost overwhelming difficulties in identifying the true author of each publication.We will address this problem by presenting a heuristic approach to author name disambiguation in bibliometric datasets for large-scale research assessments. The application proposed concerns the Italian university system, comprising 80 universities and a research staff of over 60,000 scientists. The key advantage of the proposed approach is the ease of implementation. The algorithms are of practical application and have considerably better scalability and expandability properties than state-of-the-art unsupervised approaches. Moreover, the performance in terms of precision and recall, which can be further improved, seems thoroughly adequate for the typical needs of large-scale bibliometric research assessments
