Rutas cognitivas de futuros maestros ante una situación comparativa de razones desiguales
2019
En esta investigación se analizan las rutas cognitivas que subyacen a las resoluciones de un grupo de futuros maestros ante una tarea de comparación de razones desiguales en el contexto de las ofertas comerciales. La revisión de la literatura y el análisis en profundidad de las componentes críticas de la tarea nos han permitido definir las dimensiones de análisis de las resoluciones. A partir de ellas hemos realizado un análisis cualitativo de corte interpretativo del cual se desprende que los participantes poseen un escaso desarrollo del pensamiento relativo. Un número importante de ellos presenta dificultades con la comparación de las cantidades relativas desiguales cuando estas se les pr…
Posterior meniscal root repair: a biomechanical comparison between human and porcine menisci
2019
The aim of the present study was to compare the biomechanical characteristics of posterior meniscal root repair of porcine and human menisci. Methods. In vitro biomechanical testing was performed using 12 porcine menisci and 12 human menisci. All menisci were sectioned at the midpoint of their circumference and mounted on an electro-mechanic testing machine. The posterior root was sutured with three single stitches using a no. 2 non-absorbable suture. All specimens were subjected to cyclic axial loading followed by load-to-failure testing. Displacements were recorded at the conclusion of cycles 1, 100, 500 and 1000. Further, load-displacement curves of each specimen were recorded and analyz…
Detection of a porcine-like rotavirus in a child with enteritis in Italy.
2008
ABSTRACT During a 1-year rotavirus surveillance of children hospitalized with acute gastroenteritis in Brescia Hospital, Italy, a chimerical rotavirus strain, G3P[6], was detected, displaying the VP7 and VP4 genes of porcine origin and the NSP4 and VP6 genes of human origin. The reassortant nature of the virus rules out a direct zoonotic event.
Review of group A rotavirus strains reported in swine and cattle
2013
Group A rotavirus (RVA) infections cause severe economic losses in intensively reared livestock animals, particularly in herds of swine and cattle. RVA strains are antigenically heterogeneous, and are classified in multiple G and P types defined by the two outer capsid proteins, VP7 and VP4, respectively. This study summarizes published literature on the genetic and antigenic diversity of porcine and bovine RVA strains published over the last 3 decades. The single most prevalent genotype combination among porcine RVA strains was G5P[7], whereas the predominant genotype combination among bovine RVA strains was G6P[5], although spatiotemporal differences in RVA strain distribution were observ…
Food partitioning between Serranus scriba and Scorpaena porcus (Perciformes) on the infralittoral ground of the South Tyrrhenian Sea.
1993
Food preferences of Scorpaena porcus and Serranus scriba were investigated from the stomach contents of fish caught with trammel nets in the Gulf of Palermo (Tyrrhenian Sea). Decapoda Natantia and Decapoda Brachyura were the main preferred prey in the diet of S. porcus whereas Decapoda Natantia, Decapoda Galatheidae and Pisces were the preferred prey for S. scriba. These results and the values of the index of overlapping alimentary requirements suggested competition for food resources between the two species. A more precise investigation, at species level, of the food remains of the most abundant taxon (Crustacea Decapoda) made it possible to demonstrate that the trophic niche overlap betwe…

I “camerini di porcellana” a Palazzo Comitini. Una significativa variante tra le cineserie della Palermo rococò
2011
Il saggio approfondisce un andito molto particolare del grandioso palazzo dei principi Gravina di Comitini, ovvero le salette dette “gabinetti di porcellana”. Esse sono un sintomatico esempio di aggiornamento culturale dei committenti secondo la moda e il gusto della cineserie dovuta anche alla smania collezionistica di porcellane cinesi (o europee in stile) che a Palermo, diversamente da quanto si credeva alcuni decenni fa, era molto estesa e competeva in grandiosità con i maggiori esemplari di porzellankammer europei, francesi e tedeschi. Ciò che emerge da questo contributo è la sincronia dell’aristocrazia palermitana con i fenomeni mondani d’oltralpe e la loro precisa attenzione a quei e…
I letti in lega metallica nella Palermo del XIX secolo: premesse storiche per una catalogazione in funzione museale
2009
Oggetto della ricerca è stata una particolare produzione artistico-industriale a Palermo, quella dei letti in lega metallica. Nonostante se ne sia persa memoria, già nella prima metà del XIX secolo, sulla scorta dell'influenza inglese, una cui consistente comunità era presente in Sicilia già dalla fine del secolo precedente, si assiste alla realizzazione in loco di letti in rame o altri metalli che prendono sempre più spazio, rispetto a quelli tradizionali, per gli indubbi vantaggi pratici ed economici. La diffusione è tale che alcuni elementi di arredo diventano parte del patrimonio culturale e del gusto locale, come le culle in rame e ottone. L'articolo si muove in questo solco ricostruen…
Recensione a Porcelio de’ Pandoni, De sestertio et talento, ediz. critica e trad. ital. a cura di N. Rozza, Napoli, Loffredo, 2022
2023
Review of the critical edition of «De sestertio et talento» by the Neapolitan humanist Porcelio de' Pandoni, edited by Nicoletta Rozza and Andrew Burnett and published in 2022 in Naples by the publisher Loffredo.
Porcine Model for Internal Mammary Vessels Harvesting
2018
Recipient vessels selection is crucial for successful microsurgical breast reconstruction. The internal mammary vessels (IMVs) have gained great popularity, and they are often selected as first choice recipient vessels. The IMVs can be exposed for microvascular anastomosis through a rib-removing (trans-costal) or a rib-sparing (intercostal) approach.1–3 Because the vessels are located between the rib cage and the parietal pleura, adequate training is needed to avoid and eventually manage bleedings and pleural perforation. This training is better performed in a nonhuman model. Our aim was to investigate the pig as a surgical model for IMVs harvesting to be used in training.
