Abstract
Background:Systemic juvenile idiopathic arthritis (SJIA) is characterized by extra-articular manifestations, as fever and rash, and rarely associated by a potentially lethal complication as macrophage activation syndrome (MAS). Anakinra is a recombinant human interleukin (IL)-1 receptor antagonist whose efficacy and safety profile has been studied for patients with SJIA.Objectives:To evaluate the long-term safety profile of anakinra in patients with SJIA.Methods:Data from patients with SJIA enrolled in the Pharmachild registry before 30 September 2018 and treated with anakinra were analyzed. The study endpoints were the occurrence of non-serious adverse events (AEs) of at least moderate severity and serious AEs (SAEs), including macrophage activation syndrome (MAS), and the duration of anakinra treatment with reasons for discontinuation. All endpoints were analyzed overall, by 6 month-time windows and in different treatment sets represented by those patients continuously treated with anakinra for at least 12, 18 and 24 months (set-12, -18, -24, respectively).Results:306 patients were enrolled. 46%, 34% and 28% of them had been treated for at least 12, 18 and 24 months, respectively. 201 AEs, mostly represented by infections, were reported for 509.3 patient-years (py) with an overall incidence rate (IR) of 39.5/100 py. Among 56 SAEs (IR 11.0/100 py), (Table 1) 23.2% were infections and 19.6% MAS episodes. The IR of AEs was higher during the first 6 months of anakinra, followed by decreasing IR in the different long-term treatment sets. Treatment discontinuation occurred in 76% of patients, most in the first 6 months, due to inefficacy (43%), remission (31%) or AEs/intolerance (15%). No deaths or malignancies occurred during anakinra treatment.Table 1.Number of SAEs and incidence rates (95% CI) by overall PT decreasing order and time window in the complete set (events with a frequency >1 by overall SOC and >1 by overall PT were reported) Only time windows <13 months were reported in the present table.Time window1-6 months7-12 monthsOverallN306194306Patient-time (years)117.380.2509.3SOCPTnRate (95% CI)nRate (95% CI)nRate(95% CI)AllAll3328.1 (19.1-41.5)45.0 (1.9-13.2)5611.0 (7.9-15.2)Infections and infestationsAll76.0 (2.9- 12.4)11.2 (0.2- 8.8)132.6 (1.4- 4.8)Pneumonia21.7 (0.4- 6.8)11.2 (0.2- 8.8)40.8 (0.3- 2.1)Immune system disordersAll76.0 (2.8- 12.5)11.2 (0.2- 8.8)112.2 (1.1- 4.1)Haemophagocytic lymphohistiocytosis76.0 (2.8- 12.5)11.2 (0.2- 8.8)112.2 (1.1- 4.1)Injury, poisoning and procedural complicationsAll54.3 (1.8- 10.2)--91.8 (0.9- 3.4)Infusion related reaction10.9 (0.1- 6.0)--20.4 (0.1- 1.6)Injection related reaction43.4 (1.3- 9.1)--61.2 (0.5- 2.6)Metabolism and nutrition disordersAll32.6 (0.8- 7.9)--40.8 (0.3- 2.1)Skin and subcutaneous tissue disordersAll32.6 (0.8- 7.9)11.2 (0.2- 8.8)40.8 (0.3- 2.1)Blood and lymphatic system disordersAll10.9 (0.1- 6.1)--20.4 (0.1- 1.6)General disorders and administration site conditionsAll10.9 (0.1- 6.1)11.2 (0.2- 8.8)20.4 (0.1- 1.6)InvestigationsAll21.7 (0.4- 6.8)--20.4 (0.1- 1.6)Nervous system disordersAll10.9 (0.1- 6.0)--20.4 (0.1- 1.6)Surgical and medical proceduresAll10.9 (0.1- 6.0)--20.4 (0.1- 1.5)Abbreviations: SAE, serious adverse event; SOC, system organ class; PT, preferred term, MedDRA version 21.1; N, number of patients ever treated with anakinra during the time window irrespectively of the length of any unexposed periods; 95% CI, 95% Confidence Interval.Conclusion:The results of the present study confirm the long-term safety profile of anakinra in SJIA patients and show a decreasing overall incidence rate of AEs over time.Disclosure of Interests:Gabriella Giancane Grant/research support from: The study was funded by SOBI Swedish, Riccardo Papa Grant/research support from: The study was funded by SOBI Swedish, Sebastian Vastert Grant/research support from: The study was funded by SOBI Swedish, Francesca Bagnasco Grant/research support from: The study was funded by SOBI Swedish, Joost F.

Abstract
A Candida albicans expression library was constructed from RNA isolated from regenerating protoplasts. A 1.4-kb cDNA clone was used to isolate a genomic fragment. Sequence analysis revealed an open reading frame of 593 amino acids with an overall identity of 63.6% with the phenylalanyl-tRNA synthetase beta subunit (FRS1) of Saccharomyces cerevisiae. We named it CaFRS1. It is located in a single copy in chromosome R, SfiI fragment M. Its expression showed a decrease during the cell wall regeneration process in protoplasts of both yeast and mycelial cells of C. albicans, suggesting its requirement thereof in initial steps of the cell wall synthesis.

Abstract
The structural rearrangement of human sheathed capillaries in congestive splenomegaly has been considered. In abnormal spleens the external diameter and wall thickness were decreased, while the internal diameter was increased. Moreover, the total length and the absolute number of sheathed capillaries were increased, though not as much as the whole red pulp volume. Thus, in congestive splenomegaly, in addition to the well-known changes of the sinuses, the terminal arterial passages also appear to participate in the morphological rearrangement of the red pulp. The purpose of this paper is to formulate a simple dynamic model explaining the reduction of blood flow rate in the pathologically modified spleen. The main advantage of the present approach is that the coefficients inserted in equations describing the physical phenomena have been eliminated from the final formulae. Consequently, the model does not require the determination of parameters by means of difficult experimental measurements.

Abstract
The morphological organization of the structural components in the dog carotid wall is investigated by X-ray diffraction and microscopic analysis. Histological analysis confirms an anisotropic morphology of smooth muscle cells and elastic fibers in the tissue. Collagen fibers, as revealed by X-ray diffraction technique, are organized in an isotropic network in the unstretched carotid media. Collagen fibers stretch without a preferential direction of orientation when a carotid segment is deformed in the physiological range under intraluminal pressure. A mathematical model which takes into account the isotropic distribution of the collagen fibers is developed. The validity of this model has been tested by computing several mechanical parameters using Anliker's data on the axial and radial oscillation obtained for carotids of living dogs. In spite of the anisotropic morphology of the main constituents of the carotid media layer, from a mechanical point of view the tissue can be considered as an isotropic material for the random distribution of the collagen fibers which represent the component of higher tensile strength.

Abstract
In the view of characterizing the animal tissues with respect to their physical properties, the AA. have investigated on the behaviour of the electrical responses of bovine diaphragmatic muscle. In particolar the resistance and the impedance (at a fixed frequency of 20 Hz, sinusoidal wave) have been checked in samples from the 4th up to the 148th hour after slaughter. The results of these experiments show that, during the maturation of the meat, there is a decrease of the values of the resistance and of the capacitive reactance. On the basis of the data acquired, the only hypothesis explaining the course of the research could be that the electrical properties of the meat are greatly influenced in a very relevant way by capacitive structures and in lower degree by a pure resistive medium.

Abstract
The Authors continuing a program of research on the characterization of physical properties of muscular tissues of Mammalia after slaughtering, have performed a new series of observations on the electrical conductance of femoral biceps of swine. Using two groups of specimen (one cut along the axis of the muscular fibers, the other at right angle of them), the AA. checked different values of resistance and of impedance, particularly during the first hours. On the contrary in the final stage of the research the data are quite similar in both the groups of samples. In the comment has taken into account the hypothesis that, on the basis of changes in the tissue structures, electrochemical processes could explain the results.

Abstract
Measurement of histological and cytological parameters can be performed much faster and more accurate by means of a semi-automatic device that is described in detail. The system consists mainly of a medium-sized computer and one or more peripheral terminals. Each terminal incorporates a special measurement table for data acquisition, a keyboard for manual data input, and an interface. The software program for the evaluation and storage of the digital data is simple to write and offers a high degree of flexibility to the user. The system can be operated in real time.
