Functionality of endothelial cells on silk fibroin nets: Comparative study of micro- and nanometric fibre size
2007
Biomimetic material design, such as mimicking nanostructured components of the extracellular matrix, is an actual challenge for biomaterial research with a high impact on tissue engineering and regenerative medicine. Thus, understanding the cellular response at the cell biological and molecular level and the consequences of various chemically or physically modified biomaterials is highly important. In the present study we assessed the response of human umbilical vein endothelial cells (HUVEC) and outgrowth endothelial cells (OEC) from endothelial progenitor cells to different variants of nanofibrous silk fibroin nets in comparison to microfibrous silk fibroin scaffolds with regard to cellul…
Measurements of anterior chamber depth, white-to-white distance, anterior chamber angle, and pupil diameter using two Scheimpflug imaging devices.
2014
Purpose: To compare the ocular anterior chamber depth, white-to-white distance, anterior chamber angle, and pupil diameter, as measured with two different Scheimpflug imaging devices. Methods: This transversal study included 80 right eyes from 80 subjects aged from 20 to 40 years. Their spherical equivalents ranged from -4.25 to +1.00 diopters (D). Each eye's anterior chamber depth, white-to-white distance, anterior chamber angle, and pupil diameter, were measured for far vision using both the Galilei G4 (double Scheimpflug camera) and the Pentacam HR (single Scheimpflug camera) systems. Results: Mean anterior chamber depths were calculated as 3.12 ± 0.23 mm and 3.19 ± 0.24 mm when measured…

Aims To report corneal topometric and aberrometric values in mucopolysaccharidosis (MPS) and to investigate their correlation with biomechanical corneal parameters. Methods One randomly chosen eye of 20 MPS patients with no to moderate corneal clouding and one eye of 23 healthy controls with comparable age were prospectively included into this study. Corneal surface regularity was assessed by index of surface variance (ISV), -vertical asymmetry (IVA), -height asymmetry (IHA), -height decentration (IHD); keratoconus index (KI), central keratoconus index (CKI) and Zernike indices of anterior and posterior corneal surface using Scheimpflug imaging (Pentacam). Corneal resistance factor (CRF) an…
Corneal thickness differences between type 2 diabetes and non-diabetes subjects during preoperative laser surgery examination
2016
Aims To evaluate the differences in corneal thickness between type 2 diabetes subjects with HbA1c under 7.0% and non-diabetes subjects during their preoperative laser surgery examinations. Methods The mean of five consecutive corneal thickness measurements at the central and mid-peripheral cornea was obtained by means of noncontact scanning-slit corneal topography (Orbscan Topography System II; Orbscan, Inc., Salt Lake City, UT, USA) in 35 myopic non-insulin dependent type 2 diabetes subjects (17 males and 18 females) and 48 healthy myopic controls (23 males and 25 females). Results The corneal thickness values at the central and mid-peripheral cornea were significantly higher in the diabet…
Femtosecond laser for residual refractive error correction after refractive lens exchange with multifocal intraocular lens implantation.
2008
Purpose To assess visual and refractive outcomes of femtosecond laser for residual refractive error correction after refractive lens exchange (RLE) with multifocal intraocular lens (IOL) implantation. Design Prospective, nonrandomized, masked observational case series (self-controlled). Methods Fifty-three eyes of 31 consecutive patients were submitted to femtosecond laser surgery after RLE with multifocal IOL implantation. Patients showed an average manifest refractive error (D) of M , 0.200 ± 0.490; J 0 , −0.051 ± 0.532; and J 45 , −0.007 ± 0.371. Visual acuity (VA) was measured at distance and near vision before and six months after the surgery. Results At six months after surgery, mean …
Sabratha. La necropoli a Nord-Est del Teatro nell'insula 8 della Regio IV e il riuso dello spazio urbano a scopo funerario
2012
The cemetery (m 29 x 39), excavated and restored by G. Caputo in the Thirties of the twentieth century, borders westwards the cardo which leads to the Early Christian churches of Regio III, and southwards the Theatre decumanus. The burial area comprises 84 tomb sub-divo, violated or with the gravestones moved. The burial types are: 1) the forma, attested by 43 specimens, 2) the case, rectangular or anthropomorphic, with 26 specimens, 3) nine cupae, characterized by a semi-cylindrical crown placed directly on the gravestones or on a base of limestone blocks, and 4) the mound, only one example. The space organization seems to follow clear rules: all the burials are in fact concentrated in the…
Catacomba di Villagrazia di Carini (PA). Scavi 2008-2010
2012
Il poster presenta gli esiti della ricerca archeologica nella catacomba paleocristiana di Villagrazia di Carini negli anni 2008-2010. Alla rimozione degli strati di interro alluvionale, che ingombravano i settori indagati (gallerie VII-X e cubicolo X.20), si è affiancata l'analisi delle consistenze architettoniche, che ha consentito di delineare le diverse fasi della frequentazione per uso funerario. Ulteriori interessanti dati sono emersi dall'analisi dei resti osteologici e dalle operazioni di pulitura delle pareti dagli strati fangosi, che ha riportato alla luce nuovi apparati decorativi pittorici. The text introduces the results of the archaeological excavations carried out during the y…
Lilibeo al tempo di Cicerone
2021
The volume that sees the light today is the fruit of the Study Day on "Lilibeo at the time of Cicero" held in Marsala, in the conference room of the Museo Lilibeo, on 3 May 2019 thanks to the joint effort of the Museum and the Culture and Society Department of the University of Palermo. In the short term, important changes in the council organizational structure, they led to the establishment of the Archaeological Park of Lilibeo including in a unitary structure the Lilibeo Regional Archaeological Museum, the archaeological area of Capo Boeo, which represents the main nucleus, and other state-owned archaeological areas of the urban fabric of Marsala.
Dinamiche di popolamento e processi di trasmissione culturale nel comprensorio madonita attraverso la ricostruzione della viabilità antica
2020
La ricerca sulle Madonie nasce con l’intenzione di approfondire l’evoluzione storica del popolamento sulla regione montana della Sicilia nord-occidentale. Il territorio, che solo in anni recenti è divenuto oggetto di più approfondite ricerche storico-archeologiche, si presenta estremamente ricco di risorse naturali e caratterizzato da un sostrato culturale variegato che abbraccia territori d’alta montagna, dediti ad una economia silvo-pastorale prettamente conservativa, e insediamenti costieri fortemente proiettati allo scambio e al commercio. A fine di comprendere lo sviluppo delle dinamiche d’insediamento di un’area molto estesa, si è proceduto anzitutto con la restituzione ipotetica dei …
