We read with great interest the recent publication on the comparison of the efficacy of etanercept (ETN) or etanercept plus methotrexate (MTX) versus MTX monotherapy in patients with psoriatic arthritis (SEAM-PsA trial) by Mease et al (1). The authors reported significantly greater response rates in both biologic arms versus MTX for the primary endpoint, the ACR20 response, and several secondary endpoints. Interestingly, in the discussion the authors expressed their surprise about the high efficacy level conveyed by MTX alone. This article is protected by copyright.

In this study, we explored the potential for tendon regeneration induction using an umbilical cord graft in a rabbit model of patella tendon defects. In 52 of 54 New Zealand White rabbits, the central third of the patella tendons of both hind legs was removed to create tendon defects. The rabbits were randomly divided into four groups, non-filling (NF; empty defect), re-filling (RF; defect refilled with resected tendon portion), Wharton's jelly outside (WJO; defect filled with umbilical cord graft, WJ side facing outward), and Wharton's jelly inside (WJI; same as WJO with WJ side facing inward) groups. 4 rabbits from WJO and WJI group were sacrificed for human CD 105 evaluation 1 month after surgery. Further histological, biomechanical, and gene expression analyses were performed at 3 and 6 months after surgery. The untreated patella tendons in the remaining two rabbits were harvested as normal biomechanical controls. Histological evaluation showed that the formed tissue structure fibers in the tendon defect area were much denser and more mature in the WJI group than in all other groups. Biomechanical testing showed that the failure load of the final tissue structure was the highest in the WJI group. Real-time PCR indicated that the expression of most tendon-related genes was upregulated in the WJI group at 6 months after surgery. We concluded that umbilical cord grafting induces effective tendon regeneration, particularly when the Wharton's jelly side faces inward. This article is protected by copyright.

To harness the toxicity of misfolded and damaged disease proteins, such proteins are either refolded, degraded by temporal PQC, or sequestered by spatial PQC into specific, organelle-associated, compartments within the cell. Here, we discuss the impact of vesicle trafficking pathways in general, and syntaxin 5 in particular, as key players in spatial PQC directing misfolded proteins to the surface of vacuole and mitochondria, which facilitates their clearance and detoxification. Since boosting vesicle trafficking genetically can positively impact on spatial PQC and make cells less sensitive to misfolded disease proteins, we speculate that regulators of such trafficking might serve as therapeutic targets for age-related neurological disorders. © 2020 The Authors.

DESIGN Multicentre, longitudinal study in 2 separate cohorts of patients visiting an ENT surgeon via an online survey programme. SETTING Tertiary ENT clinics. PARTICIPANTS Cohort 1 consisted of patients at their first visit at an ENT outpatient clinic with an ear complaint. Cohort 2 consisted of patients who underwent surgery, with a 3-month follow-up post-surgery. MAIN OUTCOME MEASURES Construct validity Hypothesis testing, internal consistency and inter-item correlation. Reliability Test-retest reliability. The construct approach was used for assessing responsiveness. Hypotheses were formulated based on the association between the OQUA and Glasgow Health Status Inventory (GHSI) or Global Rating Scale (GRS). RESULTS Construct validity The correlation between the individual items in the impact domain ranged from 0.424 to 0.737. Confirmatory factor analysis showed a good fit. As expected, ohn Wiley & Sons Ltd.To enhance the angiogenic capacity of tissue-engineered peripheral nerves, we have constructed revascularized tissue-engineered nerves based on a vascular endothelial growth factor (VEGF)-heparin sustained release system. However, the effects of the repair of large peripheral nerve defects are not known. In this study, we used the above revascularized tissue-engineered nerve to repair large nerve defects in rats. The repair effects were observed through general observation, functional evaluation of nerve regeneration, ultrasound examination, neural electrophysiology, wet weight ratio of bilateral gastrocnemius muscle, histological evaluation, and quantitative real-time polymerase chain reaction (PCR) analysis. The results showed that the tissue-engineered peripheral nerve based on a VEGF-heparin sustained release system can achieve early vascularization and restore blood supply in the nerve graft area. The realization of early vascularization in the area of the nerve defect greatly promotes the speed of nerve regeneration and reconstruction in the area of the nerve defect, which greatly advances the process of nerve repair and reconstruction and accelerates the restoration of the normal morphological structure and function of peripheral nerves. © 2020 John Wiley & Sons, Ltd.For a long time, the vascular tone was considered to be regulated exclusively by tonic innervation of vasoconstrictor adrenergic nerves. However, accumulating experimental evidence has revealed the existence of nerves mediating vasodilatation, including perivascular nitrergic nerves (PNN), in a wide variety of mammalian species. Functioning of nitrergic vasodilator nerves is evidenced in several territories, including cerebral, mesenteric, pulmonary, renal, penile, uterine and cutaneous arteries. Nitric oxide (NO) is the main neurogenic vasodilator in cerebral arteries and acts as a counter-regulatory mechanism for adrenergic vasoconstriction in other vascular territories. In the penis, NO relaxes the vascular and cavernous smooth muscles leading to penile erection. Furthermore, when interacting with other perivascular nerves, NO can act as a neuromodulator. PNN dysfunction is involved in the genesis and maintenance of vascular disorders associated with arterial and portal hypertension, diabetes, aging, obesity, cirrhosis and hormonal changes. For example, defective nitrergic function contributes to enhanced sympathetic neurotransmission, vasoconstriction and blood pressure in some animal models of hypertension. In diabetic animals and humans, dysfunctional nitrergic neurotransmission in the corpus cavernosum is associated to erectile dysfunction. However, in some vascular beds of hypertensive and diabetic animals, increased PNN function has been described as a compensatory mechanism to the increased vascular resistance. The present review summarizes current understanding on the role of PNN in control of vascular tone, its alterations under different conditions and the associated mechanisms. The knowledge of these changes can serve to better understand the mechanisms involved in these disorders and help in planning new treatments. BLU-945 This article is protected by copyright.

The highly ordered mesoporous material Fe-SBA-15 synthesized under weakly acidic conditions was selected as a dispersant in matrix solid phase dispersion extraction for the first time. Several parameters including the mass ratio of sample to dispersant, the type of dispersant, the grinding time and the elution condition were investigated in this work. Under the optimized condition, twenty compounds were identified by quadrupole time-of-flight mass spectrometry and seven analytes were quantified. The results demonstrated that the developed method has good linearity (r>0.9995), and the limits of detection of the analytes were as low as 0.55 ng/mL. The recoveries of all 7 analytes ranged from 97.6 to 104.6% (RSD less then 3.4%). Finally, the improved method was successfully applied to determination of five batches of Chenxiangqu samples, which provided a robust method in quality control of Chinese Patent Medicines Chenxiangqu. The developed strategy also shows its great potential in analysis of complex matrix samples. This article is protected by copyright. All rights reserved. This article is protected by copyright.

However, tools such as the R programming environment and Shiny (an R package for building interactive web apps) have made it straightforward to produce new tools to help in producing evidence syntheses. We present a new tool, robvis (Risk-Of-Bias VISualization), available as an R package and web app, which facilitates rapid production of publication-quality risk-of-bias assessment figures. We present a timeline of the tool's development and its key functionality. © 2020 The Authors. Research Synthesis Methods published by John Wiley & Sons Ltd.We report the case of an 88-year old woman referred for evaluation of increased INR. Surprisingly supratherapeutic levels of rivaroxaban was detected. Upon scrutiny of the patient's medical history, a drug-drug interaction between amiodarone and rivaroxaban persisting 3 weeks after cessation of amiodaron remains the prime suspect causing the clinical picture. Both INR and rivaroxaban levels returned to normal within 3 days of cessation of rivaroxaban. The case highlights that rivaroxaban, although highly variably, does affect INR. Furthermore, it highlights that the potential for DDIs involving amiodarone may persists for weeks or months after discontinuation. Amiodarone is predicted to increase rivaroxaban exposure, through inhibition of rivaroxaban elimination via CYP3A4 and P-gp. Elderly patients and patients with declining renal function are especially at risk of increased rivaroxaban exposure when a DDI with amiodarone occurs. © 2020 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).Ferroptosis is a form of regulated, non-apoptotic cell death characterized by excessive lipid peroxidation that can be triggered by inhibition of the cystine-glutamate antiporter, system Xc - . Sorafenib, an FDA-approved multi-kinase inhibitor drug that is used for treatment of hepatocellular carcinoma (HCC), has been shown to induce ferroptosis. Protein phosphorylation changes upon sorafenib treatment have been previously reported in patient studies and in cell culture. However, early phosphorylation changes during induction of ferroptosis are not reported. This work highlights these changes through a time course from 7 to 60 min of sorafenib treatment in human (SKHep1) HCC cells. A total of 6,170 unique phosphosites from 2,381 phosphoproteins were quantified, and phosphorylation changes occurred after as little as 30 minutes of sorafenib treatment. By 60 minutes, notable changes included phosphosites significantly changing on p53 (P04637), CAD protein (P27708), and proteins important for iron homeostasis, such as FTH1 (P02794), HMOX1 (P09601), and PCBP1 (Q15365).
