Esuli russi a Napoli e Capri tra XIX e XX secolo: Nikolaj Prachov, Nikolaj Firsov, Aleksej Zolotarev. Nuovi materiali

In the present article some unpublished manuscripts preserved in Russian libraries and archives are presentedand examined: the cycle of “ocherki” Old Naples (1940), folkloristic sketches written by the painter Nikolai Prachov (1873-1950); Tales about Italy (1902), stories with a social background by the writer, journalist and translator Nikolai Firsov (1839-1917) and Twelve Novella of Capri (1913-1949), nostalgic novels about love and the “new life” of Russian exiles in Capri of the writer, historian and critic Aleksei Zolotarev (1879-1950). The analysis of these writings enriches the line of studies of the so-called “russkaja neapolitana”, widening the boundaries of the literary conventions of Naples and surroundings like “paradise vs hell”, created by writers, artists and travellers of Romanticism and Decadence

LITTLE THINGS in 3D: robust determination of the circular velocity of dwarf irregular galaxies

Dwarf Irregular galaxies (dIrrs) are the smallest stellar systems with extended HI discs. The study of the kinematics of such discs is a powerful tool to estimate the total matter distribution at these very small scales. In this work, we study the HI kinematics of 17 galaxies extracted from the `Local Irregulars That Trace Luminosity Extremes, The HI Nearby Galaxy Survey' (LITTLE THINGS). Our approach differs significantly from previous studies in that we directly fit 3D models (two spatial dimensions plus one spectral dimension) using the software $^\text{3D}$BAROLO, fully exploiting the information in the HI datacubes. For each galaxy we derive the geometric parameters of the HI disc (inclination and position angle), the radial distribution of the surface density, the velocity-dispersion ($\sigma_v$) profile and the rotation curve. The circular velocity (V$_{\text{c}}$), which traces directly the galactic potential, is then obtained by correcting the rotation curve for the asymmetric drift. As an initial application, we show that these dIrrs lie on a baryonic Tully-Fisher relation in excellent agreement with that seen on larger scales. The final products of this work are high-quality, ready-to-use kinematic data ($\textrm{V}_\textrm{c}$ and $\sigma_v$) that we make publicly available. These can be used to perform dynamical studies and improve our understanding of these low-mass galaxies.Comment: 36 pages, 28 figures, 2 tables.

Leucoreduction of blood components. an effective way to increase blood safety?

Over the past 30 years, it has been demonstrated that removal of white blood cells from blood components is effective in preventing some adverse reactions such as febrile non-haemolytic transfusion reactions, immunisation against human leucocyte antigens and human platelet antigens, and transmission of cytomegalovirus. In this review we discuss indications for leucoreduction and classify them into three categories: evidence-based indications for which the clinical efficacy is proven, indications based on the analysis of observational clinical studies with very consistent results and indications for which the clinical efficacy is partial or unproven

Human T-lymphotropic virus and transfusion safety. Does one size fit all?

Human T-cell leukemia viruses (HTLV-1 and HTLV-2) are associated with a variety of human diseases, including some severe ones. Transfusion transmission of HTLV through cellular blood components is undeniable. HTLV screening of blood donations became mandatory in different countries to improve the safety of blood supplies. In Japan and Europe, most HTLV-infected donors are HTLV-1 positive, whereas in the United States a higher prevalence of HTLV-2 is reported. Many industrialized countries have also introduced universal leukoreduction of blood components, and pathogen inactivation technologies might be another effective preventive strategy, especially if and when generalized to all blood cellular products. Considering all measures available to minimize HTLV blood transmission, the question is what would be the most suitable and costeffective strategy to ensure a high level of blood safety regarding these viruses, considering that there is no solution that can be deemed optimal for all countries

Human parvovirus B19 and blood product safety. A tale of twenty years of improvements

Parvovirus B19 (B19V), long known to be the causative agent of erythema infectiosum (fifth disease), is not a newly emerging agent. The aim of this review is to analyse the role played by this virus in compromising safety in transfusion medicine and the progressive measures to reduce the risks associated with the virus

Strategie di documentazione per la ricerca e la comunicazione archeologica. Il caso di Faragola (Foggia, Italia)

[ES] La tecnología nos ha permitido reflexionar sobre el proceso de documentación arqueológica mediante la introducción de importantes innovaciones en todas las fases de la investigación, de recuperación de datos para el análisis, la interpretación, la reconstrucción y la comunicación de los resultados. Hoy en día los equipos arqueológicos tienen acceso directo a las nuevas herramientas y métodos en el sitio, pero a menudo sin un objetivo claro y preciso; sin ninguna pretensión de presentar un modelo, el presente documento describe una serie de experimentos de campo, y reflexiones sobre la base de la creciente utilización de computadoras en las diferentes fases de nuestra investigación.[EN] Computer technology has allowed us to rethink the process of archaeological documentation by introducing important innovations in all phases of research, from recovery of data to analysis, interpretation, reconstruction and communication of results. Nowadays archaeological teams have direct access to new tools and methods on site, but often without a clear and precise purpose; the methodological chaos that reigns over the application of computer technology to the practice of archaeology is clearly visible. Without any pretense of presenting a model, this paper describes a series of field experiments conducted on Faragola site, and reflections based on the growing use of computers in the various phases of our researchDe Felice, G.; Sibilano, MG.

Convalescent plasma. New evidence for an old therapeutic tool?

Passive immunisation for the prevention and treatment of human infectious diseases can be traced back to the 20th century. The recent Ebola virus outbreak in West Africa has turned the spotlight onto the possible use of convalescent whole blood and convalescent plasma in the treatment of infectious diseases because they are the only therapeutic strategy available in some cases, given the unavailability of vaccines, drugs or other specific treatments. Convalescent blood products could be a valid option in the treatment/prophylaxis of several infectious diseases both in association with other drugs/preventive measures and as the only therapy when a specific treatment is not available. However, there are still some issues to consider in determining the advisability of implementing a large-scale convalescent plasma transfusion programm

Comparative targeted metabolomic profiles of porcine plasma and serum

Metabolomics has been used to characterise many biological matrices and obtain detailed pictures of biological systems based on many metabolites. Plasma and serum are two blood-derived biofluids commonly used to assess and monitor the organismal metabolism and obtain information on the physiological and health conditions of an animal. Plasma is the supernatant that is separated from the cellular components after centrifugation of the blood that is first added with an anticoagulant. Serum is obtained after centrifugation of the blood that has been coagulated. The choice of one or the other biofluid for metabolomic analyses is related to specific analytical needs and technical issues, to problems derived by the collection and preparation steps, in particular when specimens are sampled from animals involved in field studies. Thus far, most of the metabolomic studies that compared plasma and serum have been carried out in humans and very little is known on the pigs. In this study, we used a targeted metabolomic platform that can detect about 180 metabolites of five biochemical classes to compare plasma and serum profiles of samples collected from 24 pigs. To also obtain a cross-species comparative metabolomic analysis, information for human plasma and serum derived from the same platform was retrieved from previous studies. Statistical analyses included univariate and multivariate approaches aimed at identifying stable and/or differentially abundant metabolites between the two porcine biofluids. A total of 154 (∼83%) metabolites passed the initial quality control, indicating a good repeatability of the analytical platform in pigs. Discarded metabolites included aspartate and biogenic amines that were already reported to be unstable in human studies. More than 80% of the metabolites had similar profiles in both porcine biofluids (average correlation was 0.75). Concentrations were usually higher in serum than in plasma, in agreement with what was already reported in humans. The univariate analysis identified 44 metabolites that had statistically different concentrations between porcine plasma and serum, of which 28 metabolites were also confirmed by the multivariate analysis. The obtained picture described similarities and differences between these two biofluids in pigs and the related human-pig comparisons. The obtained information can be useful for the choice of one or the other matrix for the implementation of metabolomic studies in this livestock species. The results can also provide useful hints to valuing the pig as animal model, in particular when metabolite-derived physiological states are relevant
