Artrite-Encefalite Caprina (CAEV) una patologia emergente nel territorio siciliano: programma volontario di eradicazione
2011
L’Artrite-Encefalite Virale Caprina è una malattia infettiva segnalata per la prima volta nel 1974; l’agente causale è stato isolato solamente nel 1979: si tratta di un virus della famiglia Retroviridae, genere Lentivirus. Il virus si diffonde principalmente attraverso colostro, latte (durante la mungitura) e, in minor misura, attraverso sangue, saliva, espettorato, secrezioni vaginali. La malattia può evolvere in forma subdola e tende ad essere sottostimata negli allevamenti infetti. Le forme cliniche negli animali adulti si presentano sotto forma di artrite e/o mastite, mentre negli animali giovani, nei quali l’evidenza è ancora più rara, si osserva sintomatologia clinica riferibile ad en…

Detection of an O-methyltransferase synthesising acetosyringone in methyl jasmonate-treated tobacco cell-suspensions cultures.
2013
Acetosyringone (3',5'-dimethoxy-4'-hydroxyacetophenone) is a well-known and very effective inducer of the virulence genes of Agrobacterium tumefaciens but the precise pathway of its biosynthesis in plants is still unknown. We have used two tobacco cell lines, cultured in suspension and exhibiting different patterns of accumulation of acetosyringone in their culture medium upon treatment with methyl jasmonate, to study different steps of acetosyringone biosynthesis. In the two cell lines studied, treatment with 100 mu M methyl jasmonate triggered a rapid and transient increase in acetovanillone synthase activity followed by a progressive increase in S-adenosyl-L-methionine: 5-hydroxyacetovan…
Agrobacterium tumefaciens-mediated genetic transformation of the cardenolide-producing plant Digitalis minor L.
2003
A repeatable transformation system has been established for Digitalis minor using Agrobacterium tumefaciens. Leaf explants from 30-day-old seedlings were inoculated with either EHA105 (carrying the nptII and gusA genes) or AGL1 (with the bar and gusA genes) strains. Among the tested factors influencing T-DNA transfer to plants, the EHA105 strain and the addition of acetosyringone to the co-culture medium increased transformation. The highest transformation efficiency (8.4%) was obtained when freshly isolated explants, soaked in a bacterial suspension with an OD 550 of 0.9, were subcultured on selection medium after a 4-day co-culture with the bacteria. Evidence of stable transgene integrati…
Design for social media engagement: Insights from elderly care assistance
2015
Abstract This paper explores an alternative view of design as an emergent process of engagement and learning, as opposed to the traditional view of systems design as a problem-solving tool. We focus on digitally enabled elderly support networks as an innovative approach to the design of elderly care assistance through social media. Our research project is conducted in the context of an Italian health-care institution and provides the empirical backdrop illustrating the ensemble artefact, the four design principles and the pragmatic outcomes of personalized elderly care interventions. These contributions add both practical and theoretical guidance and learning regarding social-media engageme…
The importance of moral sensitivity when including persons with dementia in qualitative research
2012
Author's version of an article in the journal: Nursing Ethics. Also avaliable from the publisher at: httjp://dx.doi.org/10.1177/0969733012455564 The aim of the article is to show the importance of moral sensitivity when including persons with dementia in research. The article presents and discusses ethical challenges encountered when a total of fifteen persons with dementia from two nursing homes and seven proxies were included in a qualitative study. The examples show that ethical challenges may be unpredictable. As researcher you participate with the informants in their daily life and in the interview situation, and it is not possible to plan all that may happen. A procedural proposal to …
Prediction of Maxwell – Stefan diffusion coefficients in polymer – multicomponent fluid systems
2014
Abstract Calculations of mass fluxes in multicomponent fluids based on the system of generalized Maxwell–Stefan equations (GMSE) is preferably used because Maxwell–Stefan (M–S) diffusion coefficients are symmetrical and have a clear physical meaning, as they reflect the binary friction forces between compounds in the system. For the calculation of the mass transport of a multicomponent fluid in the polymer basing on GMSE, it is necessary to have M–S diffusion coefficients. This paper proposes a method that allows their calculation using widely available self-diffusion coefficients and binary diffusion coefficients for infinitely diluted mixtures. The proposed method was compared with the me…
A computational model of postprandial adipose tissue lipid metabolism derived using human arteriovenous stable isotope tracer data
2019
Given the association of disturbances in non-esterified fatty acid (NEFA) metabolism with the development of Type 2 Diabetes and Non-Alcoholic Fatty Liver Disease, computational models of glucose-insulin dynamics have been extended to account for the interplay with NEFA. In this study, we use arteriovenous measurement across the subcutaneous adipose tissue during a mixed meal challenge test to evaluate the performance and underlying assumptions of three existing models of adipose tissue metabolism and construct a new, refined model of adipose tissue metabolism. Our model introduces new terms, explicitly accounting for the conversion of glucose to glyceraldehye-3-phosphate, the postprandial …
