The efficacy of the procedure was demonstrated by using selected peptides related to different polymeric chain origins. Resulted peptides were derivatized in a predictable manner giving a minimum of side products. The reproducibility of the developed method was demonstrated by comparing peptide elution profiles derived from six Copaxone® lots. Zeocin CONCLUSIONS Application of the AQC pre-column derivatization provides a framework that could be used as an attractive approach for monitoring the quality and characterization of NBCDs products in the pharmaceutical industry.

Electric-field control is a promising approach for achieving ultralow power spintronic devices via suppressing Joule heating. Here, cutting-edge research, including electric-field modulation of antiferromagnetic spintronic devices using strain, ionic liquids, dielectric materials, and electrochemical ionic migration, is comprehensively reviewed. Various emergent topics such as the Néel spin-orbit torque, chiral spintronics, topological antiferromagnetic spintronics, anisotropic magnetoresistance, memory devices, 2D magnetism, and magneto-ionic modulation with respect to antiferromagnets are examined. In conclusion, the possibility of realizing high-quality room-temperature antiferromagnetic tunnel junctions, antiferromagnetic spin logic devices, and artificial antiferromagnetic neurons is highlighted. It is expected that this work provides an appropriate and forward-looking perspective that will promote the rapid development of this field. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Rheumatoid arthritis (RA) is a systemic autoimmune and inflammatory disease. Our study aimed to determine the effect of saffron supplement on clinical outcomes and metabolic profiles in patients with active RA. In this randomized, double-blind, placebo-controlled trial, 66 women older than 18 years old received 100 mg/day either saffron supplement in the intervention group (n = 33) or matched placebo in the placebo group (n = 33) for a period of 12 weeks. Sixty-one patients (30 in the control and 31 in the saffron group) remained for the final analysis. No adverse effects were reported by the patients. Saffron supplementation significantly decreased the number of tender (-1.38 ± 1.66 vs. 0.10 ± 0.40, p  .05). According to the results, saffron supplements could positively and significantly improve clinical outcomes in RA patients. © 2020 John Wiley & Sons, Ltd.BACKGROUND Renal cell carcinoma with sarcomatoid differentiation (RCCs) is rare, accounting for 1%-8% of all RCC histologic subtypes. In this study, we examined 139 patients with RCCs and aimed to explore their clinicopathological features and prognostic factors. METHODS From January 2007 to January 2019, patients who were pathologically diagnosed with RCCs were included in this retrospective study. Data on clinicopathologic features and overall survival were collected. The expression of CK, vimentin, CK7, and CD10 in the sarcomatoid regions of RCCs was detected. Kaplan-Meier curves and log-rank tests were used to describe the effect of clinicopathologic characteristics on overall survival. A Cox regression model was used to evaluate risk factors for prognosis. RESULTS A total of 139 patients with RCCs were identified. The median age at diagnosis was 60 years. The median survival time of all patients was 39 months. The three- and five-year survival rates were 50.2% and 44.0%, respectively. A high pathologic T stage (pT3 and pT4), microvascular invasion, and lymph node metastasis were significant predictors of prognosis. Pathologic T4 stage and lymph node metastasis were independent prognostic factors for overall survival in patients with RCCs. Furthermore, the expression of CD10 was a prognostic factor for overall survival. CONCLUSION In this study, a relatively large cohort of patients with RCCs was analyzed. We summarized the clinicopathologic features of RCCs and explored the risk factors for prognosis. Our findings may provide valuable prediction for clinical strategy.

The chemistry of iron doped gold clusters is still not fully understood but opens up the possibility of developing new materials, e.g. of gold cages doped with iron atoms. There have been several theoretical studies on these clusters but only a few experimental studies. METHODS Laser desorption ionisation (LDI) was used for the generation of Au-Fe bimetallic clusters via laser ablation (337 nm nitrogen laser) of the synthesised nano-composite nano-gold; Fe (III) 1,3,5-benzene tricarboxylate, i.e. AuNPs, Fe-MOF, while a quadrupole ion trap time of flight mass spectrometer, equipped with a reflectron, was used to acquire mass spectra. RESULTS A AuNPs, Fe-MOF nano-composite was prepared and found suitable for the LDI generation of Aum Fen clusters. In addition to Aum +/- (m = 1-35) clusters, a series of positively and negatively charged gold-iron Aum Fen +/- ones were generated. The mass spectra exhibited evidence for the clusters containing up to five iron atoms. In total, 113 binary Aum Fen +/- clusters (m = 1-35, n =1-5) were identified in the gas phase. CONCLUSION A synthesised AuNPs, Iron (III)-1,3,5-benzene tricarboxylate MOF nano-composite was found suitable for the generation of many new gold-iron clusters and mass spectrometry was shown to be an efficient technique for the determination of the cluster stoichiometry. A broad series of over 100 bimetallic Aum Fen clusters, some of them suggested to be gold cages doped with iron atoms (for m = 12 and higher), not only demonstrate a rich and complex chemistry, but also open wide possibilities of biomedical applications.

METHODS A single-center, retrospective cohort of 980 patients undergoing open-heart valve surgery from 2013 to 2016. Time to the first readmission was analyzed using univariable and multivariable Cox proportional hazard models. Results are reported as hazard ratios (HR) with 95% confidence intervals (CI). RESULTS In total, 366 patients (37%) experienced unplanned cardiac readmission within 180 days after discharge. Within 30 days after discharge, the most frequent causes of readmission were pericardial/pleural effusions (n = 87), infections (n = 50), and atrial fibrillation/flutter (n = 45). Accordingly, infections (n = 32) were the most common cause from day 31 to 180. No powerful predictors of overall cardiac readmission were identified, but several characteristics were associated with cause-specific readmissions age ≤65 years (HR 1.
