Development of a Multifunctional Bioerodible Nanocomposite Containing Metronidazole and Curcumin to Apply on L-PRF Clot to Promote Tissue Regeneratio…
2020
Teeth extractions are often followed by alveolar bone reabsorption, although an adequate level of bone is required for reliable rehabilitations by dental implants. Leukocyte and platelet-rich fibrin (L-PRF) has been widely applied in regenerative procedures and with antibiotic and antioxidant agents could play an essential role in hard and soft tissue healing. In this work, a nanocomposite (Sponge-C-MTR) consisting of a hyaluronate-based sponge loaded with metronidazole (MTR) and nanostructured lipid carriers containing curcumin (CUR-NLC) was designed to be wrapped in the L-PRF&trade
Urban rehabilitation areas in Oporto, Portugal. A brief overview
2020
This paper establishes some preliminary outcomes of the research period carried in 2019 at CITTA – University of Porto as a visiting student. Oporto is the second largest Portuguese city and the engine of the metropolitan system of the northern region of the country. For more than 30 years local urban policies have been articulated with the EU urban policies to deal with severe urban problems and boost regeneration processes. Whilst the PhD research project is entitled – Understanding the EU’s urban agenda at the margins of Europe: lessons and perspectives – studying the case of Oporto is an opportunity to reflect on the influence and impact of the EU’s regional policy over the trajectories…
Rappresentare il cambiamento. Street art e rigenerazione urbana a Palermo
2018
Da qualche anno Palermo è oggetto di attenzione da parte di artisti che, da varie parti del mondo, hanno scelto la città quale luogo delle proprie sperimentazioni. Tale fermento ha visto il proliferare di interventi di street art, spesso strumenti di denuncia sociale, in edifici abbandonati, zone urbane degradate, lottizzazioni abusive o edificazioni a ridosso della linea di costa. Recently Palermo is the subject of attention by artists who, from various parts of the world, have chosen the city as the place of their experimentations.This ferment has seen the proliferation of street art, often instruments of social denunciation, realised in abandoned buildings, degraded urban areas, illegal …
Palermo: Living Labs for Urban Regeneration
2016
The case of Palermo is described in this chapter as an example of Human Smart City (HSC) approach transferred to an extremely weak urban context in Southern Italy. The case focuses on the processes boosted through the Territorial Living Lab established in the city to tackle the topic of citizen participation in the solution of the main city challenges. It was based on a model of incremental and adaptive process of interaction, within a co-creative ecosystem, with the aim of improving housing quality. The model was shared by the players involved in the social innovation process. It would not have been possible without the Living Lab approach and the innovative momentum of design thinking tra…
Inventare nuove città. L’area industriale dell’ex-Montedison sul fiume Platani
2018
La costruzione dello stabilimento Montedison sul fiume Platani, realizzato nel 1957-60 per produrre solfato potassico, corrisponde alla fondazione di una vera e propria città industriale con paraboloidi che hanno le dimensioni di cattedrali, imponenti torri di raffreddamento, bacino idrico artificiale, villaggio con residenze, chiesa. Questi grandi spazi abbandonati (dal 1978) sono oggi ancora disponibili all’invenzione di una città possibile improntata sull’etica ambientale e sulla valorizzazione dell’architettura. The construction of the Montedison factory on the river Platani, built in 1957-60 to produce potassium sulfate, corresponds to the foundation of a real industrial city with para…
In vitroandin vivoenhancement of osteogenic capacity in a synthetic BMP-2 derived peptide-coated mineralized collagen composite
2013
Enhancement of osteogenic capacity was achieved in a mineralized collagen composite, nano-hydroxyapatite/collagen (nHAC), by loading with synthetic peptides derived from BMP-2 residues 32-48 (P17-BMP-2). Rabbit marrow stromal cells (MSCs) were used in vitro to study cell biocompatibility, attachment and differentiation on the mineralized collagen composite by a cell counting kit, scanning electron microscopy (SEM) and real-time reversed transcriptase-polymerase chain reaction analysis (RT-PCR). Optimal peptide dosage (1.0 µg/mL) was obtained by RT-PCR analysis in vitro. In addition, the relative expression level of OPN and OCN was significantly upregulated on P17-BMP-2/nHAC compared with nH…
Photocrosslinkable polysaccharide hydrogel composites based on dextran or pullulan-amylose blends with cytokines for a human co-culture model of huma…
2016
Although a large body of research has been devoted to biomaterial development for bone tissue engineering and related medical disciplines in the last few years, novel and optimized materials especially for bone fractures of critical sizes demand continued development. In this respect, polysaccharide-based hydrogels demonstrate beneficial properties and fulfill the main requirements for a bone tissue scaffold as they are hydrophilic, biocompatible, and biodegradable. The aim of the present study was the development of a natural polysaccharide-based scaffold material that can integrate with the host tissue and support bone regeneration. For this purpose, we prepared and investigated two polym…
Direct Organogenesis from Cotyledons in Cultivars of Citrus clementina Hort. ex Tan
2011
An efficient protocol to induce shoot buds regeneration in Citrus clementina cultivars (“Monreal”, “SRA 63” and “SRA 64”) by direct organogenesis has been developed using cotyledons as explants. Cotyledons transversely cut in three segments and entire ones were cultured on Murashige and Skoog (1962) solidified medium containing vitamins, 500 mg·l−1 malt extract, 50 g·l−1 sucrose and supplemented with three different concentrations of BAP (8.8, 13.2 and 17.6 μM). In all three cultivars the entire cotyledons showed more shoot morphogenic potential than transversely cut ones and after 60 incubation days the optimum BAP concentration was 17.6 μM in “Monreal” (50% ± 2.89% of frequency regenerati…

La rigenerazione urbana di Aalborg : un modello di sviluppo sostenibile per il futuro delle città
2022
Uno dei maggiori eventi che ha portato la città di Aalborg, capoluogo dello Jutland settentrionale, alla ribalta internazionale è stato lo svolgimento della prima conferenza europea sulle città sostenibili (European Conference on Sustainable Cities and Towns). Nel 1994 il Consiglio internazionale per le iniziative ambientali locali (ICLEI – Local Governments for Sustainability) ha scelto Aalborg per riflettere in che modo le città, principali responsabili del cambiamento climatico, del consumo delle risorse del pianeta e dell’inquinamento ambientale, potessero cambiare i loro trend di sviluppo per indirizzarli verso una dimensione più sostenibile. Alla conferenza, che si è svolta sotto il p…
