Perotti traduttore degli opuscoli plutarchei De Alexandri Magni fortuna aut virtute e De fortuna Romanorum
No full textThe article focuses on the chronology of Perotti’s early translations of three opuscula Plutarchi (namely, De invidia et odio, De Alexandri Magni fortuna aut virtute and De fortuna romanorum) and on the relationship between Perotti’s translations of the two latter treatises and the preceding ones by Iacopo Angeli da Scarperia. G. Abbamonte argues that the De Alexandri
Magni fortuna aut virtute is the earliest of the three translations, and F. Stok presents a list of the testimonia transmitting the Plutarch translations made by Perotti and describes the relationship among the manuscripts
Greening warehouses through energy efficiency and environmental impact reduction: a conceptual framework based on a systematic literature review
No full textPurpose: The purpose of this paper is to propose a framework of green strategies as a combination of energy-efficiency measures and solutions towards environmental impact reduction for improving environmental sustainability at logistics sites. Such measures are examined by discussing the related impacts, motivations and barriers that could influence the measures' adoption. Starting from the framework, directions for future research in this field are outlined. Design/methodology/approach: The proposed framework was developed starting from a systematic literature review (SLR) approach on 60 papers published from 2008 to 2022 in international peer-reviewed journals or conference proceedings. Findings: The framework identifies six main areas of intervention (“green strategies”) towards green warehousing, namely Building, Utilities, Lighting, Material Handling and Automation, Materials and Operational Practices. For each strategy, specific energy-efficiency measures and solutions towards environmental impact reduction are further pinpointed. In most cases, “green-gold” measures emerge as the most appealing, entailing environmental and economic benefits at the same time. Finally, for each measure the relationship with the measures' primary impacts is discussed. Originality/value: From an academic viewpoint, the framework fills a major gap in the scientific literature since, for the first time, this study elaborates the concept of green warehousing as a result of energy-efficiency measures and solutions towards environmental impact reduction. A classification of the main areas of intervention (“green strategies”) is proposed by adopting a holistic approach. From a managerial perspective, the paper addresses a compelling need of practitioners – e.g. logistics service providers (LSPs), manufacturers and retailers – for practices and solutions towards greener warehousing processes to increase energy efficiency and decrease the environmental impact of the practitioners' logistics facilities. In this sense, the proposed framework can provide valuable support for logistics managers that are about to approach the challenge of turning the managers' warehouses into greener nodes of the managers' supply chains
Plasma procalcitonin in rheumatic diseases
No full textData on the origin and biological function of procalcitonin, the pro-hormone of calcitonin, are scarce. Since this peptide can be induced in bacterial invasive infections, serum procalcitonin levels may be useful in differential diagnosis of systemic inflammatory response syndrome. This review will focus on the clinical significance of changes in serum procalcitonin levels in patients with connective tissue diseases and other rheumatic disorders
Diagnostic value of procalcitonin measurement in febrile patients with systemic autoimmune diseases
No full textObjective. To determine the usefulness of plasma procalcitonin (PCT) measurement to suspect infectious etiology in febrile patients with systemic autoimmune disease. Methods. PCT, C-Reactive protein (CRP), erythrocyte sedimentation rate (ESR) and white blood cell count (WBC) were measured in 44 consecutive inpatients with a diagnosis of systemic autoimmune disease and fever > 38 degrees C. After careful microbiologic screening no obvious infection was demonstrated in 24 patients (Group A) while an infectious bacterial complication was diagnosed in 20 cases (Group B). Results. Median PCT levels were significantly higher in the group B (1.11 vs 0. 24 ng/ml; p = 0.0007), whereas the differences for CRP, WBC and ESR did not reach statistical significance. PCT also exhibited a good sensitivity and specificity (75%) in differentiating patients with infection from those with disease flare. With respect to positive and negative predictive values (71.4% and 78.2%), PCT markedly exceeded the other variables. By analyzing PCT values by disease we identified a false positive subgroup of patients suffering from adult onset Still's disease (AOSD), showing markedly elevated PCT levels in absence of infection. By excluding these patients, PCT showed a very good sensitivity and specificity (73.6% and 89.4%) and the area under receiver operating characteristics (ROC) curve rose from 0.801 to 0.904. Conclusion. Our data indicate that elevated PCT concentrations offer good sensitivity and specificity for the diagnosis of systemic bacterial infection in febrile patients with systemic autoimmune diseases. However in fever associated with AOSD PCT may be elevated even in the absence of infectious complication
Transplantation of peripheral blood stem cells mobilized by haematopoietic growth factors in childhood.
No full textPeripheral blood stem cells (PBSC), mobilised by means of haematopoietic growth factors (HGF) with or without chemotherapy, are being used routinely for autologous rescue after high-dose chemo-radiotherapy in paediatric patients with lymphoma and selected solid tumours because of the ease of collection and the accelerated kinetics of neutrophil and platelet engraftment as compared with bone marrow cells. Recent reports indicated that HGF-mobilised PBSC can also be employed in childhood as an alternative to bone marrow allograft when the donor is an adult or with the aim of reversing graft failure in patients who were previously given a marrow allograft. Notwithstanding this wide use of PBSC, several biological and clinical questions of crucial relevance are still unsolved. In this article, we will analyse: (1) the optimal timing for PBSC collection after cytokine-based mobilising regimens; (2) the variables affecting the yield of peripheral blood progenitors; (3) the minimum threshold and the optimal number of PBSC that should be infused for autologous and allogeneic transplant, respectively; (4) the biological mechanisms underlying mobilisation of haematopoietic stem cells into circulation; (5) the incidence of graft-versus-host disease and the biological characteristics of donor lymphocytes in patients given allogeneic transplant of PBSC; and (6) the most relevant peculiarities in the kinetics of immune recovery of patients given allogeneic transplant of PBSC, as compared to bone marrow transplant recipients
