Tissue response and biomaterial integration: the efficacy of in vitro methods

2002

Implantation involves tissue trauma, which evokes an inflammatory response, coupled to a wound healing reaction, involving angiogenesis, fibroblast activation and matrix remodelling. Until now the type and extent of such reactions to give optimal integration of various biomaterials are practically unknown. Three principal fields of research can yield useful data to understand these phenomena better: studies on explanted biomaterials, animal models and relevant in vitro techniques. This paper will present examples of the latter field and the application of endothelial cell (EC) culture systems to study the effects of important tissue (e.g. pro-inflammatory cytokines, chemokines) and material…

L’articolo illustra i primi risultati ottenuti nell’ambito dell’analisi prestazionale del vetromattone fotovoltaico, un prodotto edilizio innovativo derivato dall’integrazione di celle fotovoltaiche di terza generazione (DSSC) nel vetromattone, ideato per la realizzazione di involucri traslucidi energeticamente effi cienti ed “attivi”, in grado di ridurre i consumi energetici degli edifi ci e di produrre, al contempo, energia verde. L’analisi è stata condotta su quattro differenti ipotesi di integrazione. Attraverso simulazioni numeriche si è effettuata una valutazione dell’energia assorbita dagli strati attivi oltre che delle prestazioni ottiche complessive del dispositivo. Lo studio anali…

In this article the fi rst results of the performance analysis of the photovoltaic glassblock are given. The photovoltaic glassblock is an innovative product which integrates third generation solar cells (DSSC) invented for the construction of translucent building envelopes energetically effi cient and “active” able to reduce the energy consumption in buildings and to produce at the same time green energy. The analysis was conducted on four different hypotheses of integration through numerical simulations in order to evaluate the energy absorption and the optical performance of the device. The software simulations represent a fi rst step for the understanding of the performance of the element and prelude to an experimental analysis session. The results of a research conducted about national and international patents publications on the DSSC technology and its applications will be illustrated too. The data collected during this research had been organized in a digital database.Settore ICAR/10 - Architettura Tecnica

Observational study: The use of the ventralight Echo PS (positioning system) prosthesis in the treatment of incisional hernia

2020

The treatment of incisional hernias, especially those that are multiple or recurring, has always represented important challenges for surgeons. An incisional hernia is a mechanical damage of the abdominal wall that can result in respiratory problems and alterations of splanchnic circulation, especially when in large size hernias. The increasing availability of prostheses with greater resistance Romato infections and tension, lightness, biocompatibility, and reduced visceral adhesions has improved outcomes and minimized relapses. It is still important, however, to carefully choose the type of prosthesis and surgical technique, whether laparotomic or laparoscopic, correlated to the positionin…

Diagnosis and therapeutic management of primary headache in an emergency setting

2013

Introduction and aim: Much headachers are under or mis-diagnoses and data regarding the proportion of patients attending an emergency department (ED) because of headache are still few. We conducted a retrospective observational study in an ED with the following aims: (a) estimate the proportion of headache attending to an ED (b) to estimate and describe the therapeutic management of primary headache and (c) to assessment the exam most frequently requested. Materials and methods: We collected data regarding patients diagnosed with headache consecutively attending the ED of the University of Palermo between September 2011 and March 2012. The study was approved by the ethics committee. Results: Between the semester evaluated 25110 subjects were admitted to ED headache suffers were equal to 1.6 %. Of these 263 (63.1 %) were woman and 154 (36.9 %). Mean age was 44.2 (DS ± 18.4) years (p = 0.068).According to ED registry headache admission was as follow assigned: 76.5 % with a diagnosis of headache 22.8 % with a secondary headache 0.7 % with Trigeminal Autonomic Cephalgias (TACs). Among those with a primary headache about 36 % of patient did not received a pharmacological treatment. Monotherapy was prescribed less frequently than combination therapy (19.1 vs 44.5 %).In monotherapy the most frequent medication were NSAIDs (28.3 %) benzodiazepines (26.7 %) and dopamine antagonists (11.7 %). Among those with a primary headache a CT scan was performed in the 124 subjects and 111 (34.8 %) had a neurologist consultation. Discussion: Our data are in line with the one previously reported in literature. The most frequently medication in the Italian ED were NSAIDs benzodiazepines dopamine antagonists and steroids. Neverless our data unlikely can be compared to other study give a snapshot. We believe that much more can be done to improve treatment of primary headache in ED.Settore MED/26 - Neurologia

Closed foldable capsular rings

2004

A new foldable capsular tension and bending ring system with a sharp-edged design is described. The closed foldable capsular rings (CFCR) consist of 8 hydrophobic and 8 hydrophilic ring segments. The CFCRs have a 9.2 mm minimum overall diameter. The CFCRs were inserted using various cartridge systems or a two-folded technique with a forceps. The CFCRs were implanted after phacoemulsification through a small (1.6 to 3.2 mm) incision in 104 human adult eyes without intraoperative complications. No postoperative complications such as capsule folds or inward bending were observed over a 6-month follow-up. Posterior capsule opacification was minimal or absent in all eyes.

Il Dioniso delle "Baccanti" e i "piegatori di pini". Polivalenza di un'immagine leggendaria

2021

This paper investigates the mythical and ritual background of Dionysus’ representation as “fir-bender” in Euripides’ "Bacchae" (ll. 1061 ff.), in an attempt to shed light not only on the dramaturgical aspects of the tragic plot, but also on the cultural categories that make this representation intelligible to the Athenian audience at the end of the fifth century BC. Following Louis Gernet’s historical-anthropological approach based on the notion of "polyvalence des images", this paper aims to define a mythical pattern – the connection between the bending of a tree and the dismemberment of a human victim – already attested in the Attic legend of Theseus and Sinis, in which both characters se…

Evolución histórica de la autonomía de la voluntad en el Derecho matrimonial

2021

The autonomy of the will or power of self-regulation of relationships derived from marriage is a subject that is on the rise and that we can qualify as novel. More and more couples are opting to proceed making use of this power to self-regulate both personal and property effects derived from their union or its future breakdown. In the Spanish legal system there is no precise and complete regulation of the subject, without all these figures being equally legislated, although all are admitted without any doubt by jurisprudence. In recent years there has been an evolution of Family law, traditionally very reluctant to give space to self-regulation. Our Constitution marks a turning point by cha…

The titanium-made growth-guidance technique for early-onset scoliosis at minimum 2-year follow-up: A prospective multicenter study.

2019

Background The management of early-onset scoliosis (EOS) remains a serious challenge in pediatric orthopedics. The growth-guidance system (GGS) is a surgical option that allows continuous growth along a rod, averting the need for repeated operative lengthening. Objectives The objective of this study was to evaluate the outcomes of the GGS in the treatment of EOS. Material and methods A prospective study, including 81 patients from 4 departments treated with this method from 2013 to 2015, was conducted with a minimum follow-up period of 24 months. The follow-up data of 57 patients was available, thus the drop-out rate was 29.63%. There were 44 girls with a mean age of 10.03 years and 13 boys…
