An updated checklist of chondrichthyans of Calabria (Central Mediterranean, southern Italy), with emphasis on rare species
2020
In this contribution the checklist of chondrichthyans of Calabria (Central Mediterranean, southern Italy) is reported. Data presented is derived from twenty years of opportunistic and active surveys from 2000 to 2020. A total of 55 species of chondrichthyans is present in Calabrian seas: 33 sharks, 20 rays, and 2 chimaeras. These species represent approximately 62% of the total reported for the Mediterranean. Approximately 71% of Calabrian species have been reported in the Tyrrhenian Sea, 49% in the Ionian Sea, and 33% in the Strait of Messina. According to IUCN criteria, new records of Endangered and Critically Endangered species (i.e., Carcahrodon carcharias [Linnaeus, 1758], Lamna nasus …
Reaction of 3-Amino-1,2,4-Triazole with Diethyl Phosphite and Triethyl Orthoformate: Acid-Base Properties and Antiosteoporotic Activities of the Prod…
2017
The reaction of diethyl phosphite with triethyl orthoformate and a primary amine followed by hydrolysis is presented, and the reaction was suitable for the preparation of (aminomethylene)bisphosphonates. 3-Amino-1,2,4-triazole was chosen as an interesting substrate for this reaction because it possesses multiple groups that can serve as the amino component in the reaction-namely, the side-chain and triazole amines. This substrate readily forms 1,2,4-triazolyl-3-yl-aminomethylenebisphosphonic acid (compound 1) as a major product, along with N-ethylated bisphosphonates as side products. The in vitro antiproliferative effects of the synthesized aminomethylenebisphosphonic acids against J774E m…
Neighbourhoods in Bucarest: recognition, conservation and inheritage
2012
Il contributo traccia le linee-guida per una proposta di conservazione integrata di un quartiere residenziale periferico di Bucarest, costruito tra Ottocento e Novecento, attraverso il riconoscimento dei suoi valori culturali e di autenticità, pur non disgiunti da reali possibilità di riuso e da un adeguamento, in termini prestazionali, alle esigenze contemporanee.
Effects of zoledronic acid and dexamethasone on early phases of socket healing after tooth extraction in rats : a preliminary macroscopic and microsc…
2018
Background The exact pathogenesis of medication-related osteonecrosis of the jaw (MRONJ) is still unknown. The aim of this paper was to investigate the effects of zoledronic acid and dexamethasone on the early phases of socket healing in rats subjected to tooth extractions. Material and Methods Thirty male Sprague-Dawley rats were divided into 2 groups: pharmacologically treated group (T, n=20) and non-pharmacologically treated group (C, n=10). T group rats received 0.1 mg/Kg of zoledronic acid (ZOL) and 1 mg/Kg of dexamethasone (DEX) three times a week for 10 consecutive weeks. C group rats were infused with vehicle. After 9 weeks from the first infusion, first maxillary molars were extrac…

Grazie alla convenzione sottoscritta dal Dipartimento di Architettura e la Soprintendenza per i Beni Culturali e Ambientali di Palermo è stato possibile effettuare un particolareggiato rilievo dello stato di conservazione del monumento e presentare dei progetti p…
I grandi alberi dei Nebrodi
2012
In questo libro sono presentati i risultati di una ricerca portata avanti dagli Autori, botanici del Dipartimento di Biologia ambientale e Biodiversità dell’Università di Palermo. L’indagine ha riguardato sia ambienti di tipo forestale sia di tipo agricolo tradizionale ed ha messo in luce un ricco patrimonio arboreo di tipo monumentale. Significative sono le immagini relative ai grandi aceri, ai ragguardevoli individui di due specie endemiche dei Nebrodi (Pyrus vallis-demonis e Malus crescimannoi) e al faggio di Fago scuro che rappresenta il patriarca di tutti i faggi d’Italia. Dopo il 150° dell’Unità d’Italia non poteva mancare il Grande Pino piantato in concomitanza dello sbarco di Giusep…
Comparative Chemical Characterisation of Soils at Cypripedium Calceolus Sites in Latvia
2017
Abstract The main aim of the study was to evaluate the soil chemical characteristics of Cypripedium calceolus sites in Latvia for understanding of the species ecology, and its conservation problems and possibilities. Soil for 27 C. calceolus sites in Latvia was analysed during 2007-2015. The concentration of plant available essential nutrients (N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, Mo, B), soil pH, electrical conductivity and concentration of organic matter were determined. Nutrient concentration of C. calceolus leaf samples from six sites were determined. The results demonstrated high heterogeneity in soil chemical composition with high variation for Ca, Mg, and Mn. The results suggest some …
Soil loss tolerance in the context of the European Green Deal
2023
Soil erosion by water, and the consequent loss of a non-renewable resource, is a relevant environmental issue which has economic, ecologic, and social repercussions. In the context of the European Green Deal, the increasing awareness of soil Ecosystem Services is leading to give the due relevance to this problem. Notwithstanding the recent soil conservation strategies adopted by the Common Agricultural Policy had positive effects, the concern regarding this topic is drastically increasing for the normalization of extraordinary rainfall events due to climate change. Recent events occurred in Europe demonstrated that landscape protection is often inadequate and interventions to prevent damage…
Good practices and actions for sustainable municipal solid waste management in the tourist sector
2018
This paper deals with waste management in the tourism sector, specifically in the agro-tourism structures. Two regions of Romania and Italy have been considered as case studies in order to promote good practices and actions for sustainable municipal solid waste management. Specific criteria to adopt for the sustainable consumption of beverages and food and for the sustainable use of packaging of various types have been analyzed and suggested. The adoption of an indicator at the level of the single tourist structure has been proposed to help self-analysis that is aimed at setting the priorities of intervention for improving its environmental sustainability.
