The role of two non-indigenous serpulid tube worms in shaping artificial hard substrata communities: case study of a fish farm in the central Mediter…

2019

Understanding the spread and establishment of non-indigenous species (NIS) is one of the primary areas of focus in bioinvasion science and is essential for generating appropriate management strategies in aquaculture. Here we investigated the role of 2 non-indigenous serpulid tube worms (Hydroides elegans and H. dirampha) in shaping the hard substrata communities around a fish farm in the Strait of Sicily over 1 yr (June 2014-June 2015), at 3 mo intervals (September and December 2014, March and June 2015). The mean density values of serpulids were significantly different at each sampling time. The density of serpulids on submerged panels showed a peak in spring (March 2015, after 9 mo) and d…

IN THE SEARCH OF LEPTIN AGONISTS AS ANTI-OBESITY DRUGS: PROTEIN/PROTEIN DOCKING, MOLECULAR DYNAMICS, AND VIRTUAL SCREENING

2012

The body weight control is a mechanism thinly regulated by several hormonal, metabolic, and nervous pathways (1). Recessive homozygous mutations in the ob/ob and db/db mouse strain cause extreme obesity. The products of the ob and db genes are leptin and its receptor, respectively. The leptin receptor is crucial for energy homeostasis and regulation of food uptake. Leptin is a 16 kDa hormone that is mainly secreted by fat cells into the bloodstream. Under normal circumstances, circulating leptin levels are proportionate to the fat body mass. Sensing of elevated leptin levels by the hypothalamic neurocircutry activates a negative feedback loop resulting in reduced food intake and increased e…

Parte IV. Cap IV. Impresa agricola e mercato agro-alimentare

2021

The chapter addresses the liability profile of the agricultural producer. The aim is to identify a new model of responsibility of the agricultural producer according to the provisions contained in the Italian Civil Code from a European viewpoint. A model of multilevel responsibility that focuses on the agricultural activity in its moment of production and marketing of the agricultural product, but also in the pursuit of sustainability objectives through non-market services.

Valoración del cumplimiento de un programa de escuela de espalda vs el tratamiento farmacológico en la lumbalgia crónica

2015

Introducción y Objetivos: La Escuela de Espalda es una alternativa terapéutica y de prevención secundaria en el tratamiento de la lumbalgia crónica que pretende entre otras hacer al paciente conocedor de su patología, que adquiera hábitos saludables e implicarle en su manejo y cuidados, Así mismo es bien conocida la dificultad para que los pacientes cumplan con los tratamientos y recomendaciones que el médico les prescribe, por lo que en la presente Tesis Doctoral se proponen los siguientes objetivos: 1. Valorar el grado de cumplimiento de la Escuela de Espalda (EE) utilizada como estrategia terapéutica en pacientes con dolor lumbar crónico. 2. Valorar el grado de cumplimiento del tratamien…

L’impresa mafiosa? Colletti bianchi e crimini di potere

2016

Assumendo una prospettiva multidisciplinare e partendo dai risultati di una ricerca condotta sul campo tra il 2013 e il 2015, il volume esamina il complesso network delle relazioni interne ed esterne a due gruppi di imprese sequestrate e confiscate per infiltrazioni mafiose, osservandone i cambiamenti negli aspetti economici, finanziari, organizzativi e sociali sia nel periodo che precede il sequestro o la confisca, sia nel periodo in cui il provvedimento è in corso. L’elevato dinamismo che caratterizza i crimini messi in atto dagli imprenditori coinvolti e il contesto in cui avvengono rendono assimilabili, sotto molti punti di vista, i casi considerati alla cosiddetta criminalità dei colle…

Cell Uptake Enhancement of Folate Targeted Polymer Coated Magnetic Nanoparticles

2013

Dual targeted drug delivery systems represent a potential platform for developing efficient vector to tumor sites. In this study we evaluated a folate- and magnetic-targeted nanocarriers based on 10 nm iron oxide nanodomais coated with the properly synthesized and characterized folic acid (FA)-functionalized amphiphilic copolymer PHEA-PLA-PEG-FA. FA was chemically conjugated to one end of diamino-polyethylene glycol of 2000 Da, in order to ensure its exposition on the polymer coated magnetic nanoparticles (MNPs-FA). The prepared nanoparticles have been exhaustively characterized by different methods, including DLS, SEM, FT-IR and magnetic measurements. Magnetic nanoparticles showed dimensio…

Current agri-environmental policies dismiss varied perceptions and discourses on management of traditional rural biotopes

2017

Abstract Traditional rural biotopes (TRBs) are threatened habitats that host significant biodiversity and several ecosystem services, and depend on active management such as low-intensity grazing. The current study explores private landowners’ decision-making on TRB management and abandonment within a social-ecological system framework. We provide insight into supporting resilience of TRB systems in the face of agricultural modernization. Using a mixed methods approach with content analysis and Q analysis, we demonstrate that TRB management fosters cultural, biological, aesthetic, and utilitarian values. These are reflected in different ways through conservationist’s, profit-oriented farmer…

Data from: Intensive aquaculture selects for increased virulence and interference competition in bacteria

2016

Although increased disease severity driven by intensive farming practices is problematic in food production, the role of evolutionary change in disease is not well understood in these environments. Experiments on parasite evolution are traditionally conducted using laboratory models, often unrelated to economically important systems. We compared how the virulence, growth and competitive ability of a globally important fish pathogen, Flavobacterium columnare, change under intensive aquaculture. We characterized bacterial isolates from disease outbreaks at fish farms during 2003-2010, and compared F. columnare populations in inlet water and outlet water of a fish farm during the 2010 outbreak…
