Effects of wild boar grazing on the yield of summer truffle (Tuscany, Italy)
The research presented here seeks to describe the impact of wild boar to a natural truffle ground of Tuber aestivum Vittad. on Monte Amiata (Tuscany – Italy). Pedoclimatic analyses indicated that the selected area could be considered suitable for the truffle production. Then classification of the vegetation of a Quercus cerris forest was carried out exploring the possibility of the BACI (Before-After-Control-Impact) sampling design. Finally 10 plots were selected, half of which have been fenced. For the first time the impact of wild boar was evaluated by estimating the surface area turned over by its activity. Moreover in each plot the number and weight of summer truffles was performed every 10 days during the fruiting period (June-November 2006-2008). The hypothesis that the presence of Sus scrofa has a strong negative influence on truffle harvesting has been amply confirmed by the data presented here, given the large increase of fruiting bodies of the summer truffle collected in the fenced plots. Consequently the destructive behaviour of the wild boar imply not only an ecological but also an economic damage in areas in which non-wood forest products are an important source of income
PD1, CTLA4 and TIGIT Expression on T and NK Cells in Granulomatous Diseases: Sarcoidosis and ANCA-Associated Vasculitis
Sarcoidosis is a granulomatous diseases affecting the lungs. Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a histologically granulomatous B-mediated disorder characterized by activated T cells. The expression of immune checkpoint (IC) molecules (PD1, CTLA4, TIGIT) on T- and NK-cells negatively regulate the T-cell immune function. The present study aimed to explore the peripheral distribution of IC molecules to better elucidate their peripheral tolerance failure, which might reflect the development of diseases. Patients referred to Respiratory Diseases and Rheumatology Unit of Siena University Hospital were prospectively and consecutively enrolled. Healthy subjects were also enrolled as a control group. Multicolor flow cytometric analysis was performed to detect IC molecules in the peripheral blood of patients. Twenty-three patients were consecutively and prospectively enrolled in the study: 11 patients had an AAV diagnosis and 12 had sarcoidosis. CD4+PD1+ cells were higher in sarcoidosis and GPA than in HC (p = 0.0250 and p = 0.0253, respectively). CD56+CTLA4+ were higher in sarcoidosis than GPA, MPA and HC (p = 0.0085, p = 0.0042 and p = 0.0004, respectively). CTLA4+NK cells clustered for 100% of sarcoidosis patients according to decision tree analysis, while PD1+CD4 and CD8 cells for clustered for 100% of GPA patients. Our analyses showed substantial differences between sarcoidosis and AAV, further confirming the immunological peculiarity of this disease. Despite these advances, the pathogenesis remains incompletely understood, indicating an urgent need for further research to reveal the distinct immunological events in this process, with the hope to open up new therapeutic avenues and, if possible, to develop preventive measures. © 2022 by the authors

Prolonged higher dose methylprednisolone vs. conventional dexamethasone in COVID-19 pneumonia: a randomised controlled trial (MEDEAS)
Dysregulated systemic inflammation is the primary driver of mortality in severe COVID-19 pneumonia. Current guidelines favor a 7-10-day course of any glucocorticoid equivalent to dexamethasone 6 mg·day-1. A comparative RCT with a higher dose and a longer duration of intervention was lacking

Labour Control Regimes and Social Reproduction: Some Reflections on the Strengths and Weaknesses of an Evolving Framework
Sequential Pattern Mining with Temporal and Content Constraints
A tool for extracting sequential patterns with temporal and content constraints from logs is presented. The heart of the tool is a new algorithm capable of handling temporal constraints and itemsets with multiple occurrences of the same item. Applications of the system are discussed in the context of monitoring logs registered by a platform supporting distributed processes, developed within the European project BRITE
Valorizzazione della produzione di Tuber aestivum Vittad. In tartufaie naturali presenti nel Monte Amiata e nel Monte Cetona.
Rapporto fra la gestione dei soprassuoli forestali e produzione di Tuber aestivum Vitt. in una tartufaia naturale del Monte Amiata (Toscana-Italia): primi risultati.
Exploitation and Global Value Chains
Concerns about exploitation in global supply chains are increasingly central to public and academic agendas. These issues have been investigated over the last 15 years from global value chain and global production network perspectives (henceforth 'chain' analysis). The majority of chain analysis, however, portrays exploitation as something that can be 'cured' i.e. extrinsic to the operations of the world of value chains and production networks, as opposed to inherent to it. In this chapter we show how throughout global production - in Indian garments, African horticulture and oceanic shipping that bring such commodities to their markets - exploitation appears as an increasingly complex process, shaped by combinations of social relations, actors and institutions. We show how dynamics of exploitation extend beyond the production process into spheres of social reproduction, the globalisation of production and chain governance, and the social relations of credit and finance
