There is still an unmet need for a simple and reliable biomarker for the diagnosis of spondyloarthritis. Recent studies indicated that anti-CD74 antibody could act as a biomarker for spondyloarthritis. Therefore, this review aims to evaluate the levels of anti-CD74 IgG and IgA antibodies in spondyloarthritis and the diagnostic value of anti-CD74 antibodies.

PubMed, Web of Science and Medline were comprehensively searched from inception to August 7th, 2019. The pooled standard mean difference (SMD) with 95% confidence interval (CI) was used to estimate the differences of the levels of anti-CD74 IgG and IgA antibodies between spondyloarthritis patients and controls. Sensitivity, specificity and summary receiver operating characteristics (SROC) curve were used for evaluating the diagnostic value of anti-CD74 antibodies. The use of fixed-effect or random-effects model depended on heterogeneity.

Among 55 searched studies, 9 studies were finally included for analysis. Anti-CD74 IgG and IgA antibodies were both significantly increased in spondyloarthritis patients compared with matched controls (IgG SMD=0.88, 95% CI=0.55 to 1.21; IgA SMD=0.98, 95% CI=0.68 to 1.28). The pooled sensitivity, specificity and area under the SROC curve of anti-CD74 IgG antibodies were 0.61, 0.90 and 0.8881, while these indicators of anti-CD74 IgA antibodies were 0.59, 0.95 and 0.8671, respectively.

Anti-CD74 IgG and IgA antibodies were significantly increased in spondyloarthritis patients and suggest a high diagnostic specificity of spondyloarthritis. Anti-CD74 antibody could potentially be a biomarker for the diagnosis of spondyloarthritis, but many open questions remain.

To assess drug retention rates (DRRs) and reasons for discontinuation of biologic disease-modifying antirheumatic drugs (bDMARDs) in a large monocentric cohort of patients withadult onset Still's disease (AOSD).

Clinical data of AOSD patients treated with at least one bDMARD and followed up at our Center were retrospectively evaluated. Data about disease duration, number of previous bDMARDs, concomitant treatments, and reasons for therapy discontinuation were collected. Survival curves were examined by the Kaplan-Meier method and compared using a stratified log-rank test. 24-month DRRs were calculated for each bDMARD. Hazard ratio (HR) for previous bDMARD use was evaluated.

Forty-two AOSD patients received a total of 79 bDMARD-courses. Anakinra (ANK; n=41) was the most frequently used bDMARD, followed by tocilizumab (TCZ; n = 21) and Tumor Necrosis Factor inhibitors (TNFi; n=17). Biologic agents were administered concomitantly with prednisone in all cases (mean dose, 23±18mg/day) and with csDMARD therapy in 54 (68%) of courses. Thirty-six (46%) treatment courses were discontinued by 24 months. DRRs at 24 months were 62.5% for TCZ, 53.1% for ANK, and 11.8% for TNFi. ANK and TCZ DRRs were similar (p=0.576), but significantly higher than TNFi (p=0.015). Previous biologic therapies did not impact DRR (HR 0.73, 95% CI=0.40 - 1.31, p=0.288).

In our AOSD study population, 24 months DRRs of TCZ and ANK were similar and significantly higher than the TNFi DRR. Previous use of biologic agents did not affect DRRs.

The desire to apply ultrasonic testing to geometrically complex structures, and to anisotropic, inhomogeneous materials, together with the advent of more powerful electronics and software, is constantly pushing the applicability of ultrasonic waves to their limits. General ray tracing models, suitable for calculating the proper incident angle of single element probes and the proper time delay of phased array, are currently required. They can support the development of new imaging techniques, as Full Matrix Capture and Total Focusing Method, and the execution of very challenging ultrasonic inspections. This paper introduces a generalized iterative method for the computation of ultrasonic ray paths, when ultrasonic source and target are separated by multiple complex material interfaces in the two dimensional and three dimensional domains. The manuscript starts with a review of the well-known bisection method, and extends the applicability of the method to cases with increasing complexity. An application example, in the field of in-process weld inspection, shows that the introduced generalised bisection method can enable the computation of optimum incidence angles and focal delays for accurate ultrasonic focusing. There is no restriction on the analytical interfaces to be surjective. Interface folding is permitted. It is not necessary to know, a priori, with what sequence the interfaces are crossed by the rays. The presented implementation of the method completes each iteration of the bisection method in 4 ms, for a case with a single interface, and in 960 ms for the case with 52 interfaces.The importance of RAC tracking in human biofluids has boosted many demands for designing an ultrasensitive tool to determine the trace value of the RAC from clinical, judicial, and forensic centers. In this study, an electrochemical biodevice has developed for the highly selective detection of this illegal feed additive under a double recognition strategy of the aptamer (Apt) and molecular imprinting polymer (MIP) on a glassy carbon electrode (GCE). The sensing relies on this fact that both the MIP and Apt act synergistically to trap the RAC molecules. The sensing surface fabrication steps have been monitored by some electrochemical techniques such as electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV(. The charge transfer resistance (Rct) value of the redox probe as a representative of the biodevice response has increased linearly with the RAC concentration increasing in a dynamic range of 1 fM to 1.90 µM. The detection limit (LOD) value has been estimated to be 330 aM, lower than all of the reported methods in the RAC sensing. Furthermore, the practical feasibility of biodevice has been evaluated in some human blood serum and urine samples. This strategy offers some useful advantages in reliable detection of the RAC, which may help in the routine analysis, as mandated by regulatory agencies.A range of energy fuels (ethanol, char, oil/wax and gas) was produced from fibre waste contaminated with plastic through the application of a fermentation-pyrolysis route. The fibre component was first converted to ethanol by simultaneous saccharification and fermentation (SSF), achieving an ethanol concentration of 39.8 g/L. The residue, enriched in lignin and plastics, was subjected to fast pyrolysis at temperatures between 350 and 550 °C. A wax product with a higher heating value (HHV) higher than 28 MJ/kg was obtained for temperatures higher than 450 °C, while values lower than 15 MJ/kg were observed for the oils produced from the untreated waste stream. Pyrolysis at 550 °C produced a wax with an HHV as high as 32.1 MJ/kg, where 51.8% of the energy content of the fermentation residue was transferred. The attractive energy contents of the pyrolysis products were enabled by oxygen removal from the feedstock during fermentation to ethanol.Alternative materials with added-value functions, such as phytopathogen suppression and biostimulant and/or biofertilising activity, have been proposed as peat substitutes in growing media. The aim of this work was to evaluate the effect of 23 agro-industrial composts as components of growing media for baby-leaf lettuce transplant production and their activity against the plant pathogen Pythium irregulare. The composts were produced by mixing different starting feedstocks-tomato waste, leek waste, olive mill cake and vineyard pruning waste-with different additives (coffee, thyme, lavender and rockrose waste), which were incorporated at the beginning of the maturation phase. The results obtained indicated that the composts were mature enough to be used as growing media. The fresh weight of the lettuce plants grown with the different composts was significantly higher than in plants obtained with peat. Composts with the coffee additive produced higher lettuce fresh weight, while those with thyme yielded a lower fresh weight. Moreover, composts as components of growing media showed significantly higher P. irregulare suppressiveness than peat. The composts with additives produced lower lettuce fresh weight than composts without additives, but showed higher suppressiveness. Composts with additives showed opposite results depending on whether they were exposed to pathogens or not. Composts with additives showed opposite results according to pathogen pressure or not. Out of all the composts studied, the compost with tomato waste and leek waste as the initial feedstock, and lavender as an additive, showed the highest suppressive capacity. MAPK inhibitor After lettuce harvesting, the growing media with composts showed significantly lower concentrations of P. irregulare than peat. Principal Component Analysis (PCA) revealed that the growing media with compost can be grouped together according to the additive type.This research investigates the use of seven natural deep eutectic solvents (NADESs) for valorisation of orange peel waste, with the final goal to propose a unique NADES for integrated biorefinery. Initial screening of NADESs revealed the excellent ability of cholinium-based NADES with ethylene glycol as hydrogen bond donor (ChEg50) to serve as a medium for orange peel-catalysed kinetic resolution (hydrolysis) of (R,S)-1-phenylethyl acetate with high enantioselectivity (ee = 83.2%, X = 35%), as well as it's stabilizing effect on the hydrolytic enzymes (hydrolytic enzymes within ChEg50 peel extract were stabile during 20 days at 4 °C). The ChEg50 also showed a satisfactory capacity to extract D-limonene (0.5 mg gFW-1), and excellent capacity to extract polyphenols (45.7 mg gFW-1), and proteins (7.7 mg gFW-1) from the peel. Based on the obtained results, the integrated biorefinery of orange peel waste using ChEg50 in a multistep process was performed. Firstly, enantioselective kinetic resolution was performed (step I; ee = 83.2%, X = 35%), followed by isolation of the product 1-phenylethanol (step II; h = 82.2%) and extraction of polyphenols (step III; h = 86.8%) from impoverished medium. Finally, the residual orange peel was analysed for sugar and lignin content, and results revealed the potential of waste peel for the anaerobic co-digestion process. The main bottlenecks and futures perspective of NADES-assisted integrated biorefinery of orange peel waste were outlined through SWOT analysis.
