BACKGROUND: Articular erosions correlate with disability in rheumatoid arthritis (RA). Biologic treatments for RA reduce erosion progression, but erosion healing occurs infrequently. The goal of this study was to assess the effects of the anabolic agent teriparatide on joint erosion volume in RA patients treated with a tumor necrosis factor inhibitor (TNFi). METHODS: We conducted a randomized controlled trial in 24 patients with erosive RA, osteopenia, and disease activity controlled on a TNFi for at least three months...

OBJECTIVES: In current management paradigms of Rheumatoid Arthritis (RA), patient global assessment (PGA) is crucial to decide whether a patient has attained remission (target) or needs reinforced therapy. We investigated whether the clinical and psychological determinants of PGA are appropriate to support this important role. METHODS: This was a cross-sectional, single centre study including consecutive ambulatory RA patients. Data collection comprised swollen (SJC28) and tender joint counts (TJC28), C-Reactive protein (CRP), PGA, pain, fatigue, function, anxiety, depression, happiness, personality traits, and comorbidities...

The surface structure, biocompatibility, textural and adhesive properties of calcium hydrogels derived from 1, 2 and 4% solutions of apple pectin were examined in this study. An increase in the pectin concentration in hydrogels was shown to improve their stability toward elastic and plastic deformation. The elasticity of pectin hydrogels, measured as Young's modulus, ranged from 6 to 100 kPa. The mechanical properties of the pectin hydrogels were shown to correspond to those of soft tissues. The characterization of surface roughness in terms of the roughness profile (Ra) and the root-mean-square deviation of the roughness profile (Rq) indicated an increased roughness profile for hydrogels depending on their pectin concentration...

The glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) exenatide and lixisenatide reduce cholecystokinin (CCK)-induced gallbladder emptying in healthy subjects. It is unknown if all GLP-1 RAs share this effect; therefore, the effect of the GLP-1 RA albiglutide on gallbladder function was assessed. In this randomized, double-blind, 2-way crossover study, a single dose of subcutaneous albiglutide 50 mg or placebo was administered to 17 healthy subjects, and CCK-induced gallbladder contractility was measured by ultrasonography...

BACKGROUND: Previous reports suggest that Biventricular pacing (BiVp) fused with intrinsic conduction (BiVp-fusion, triple wavefront fusion) is associated with improved resynchronization compared to pure-BiVp in cardiac resynchronization therapy (CRT). This study aimed to assess the association between acute hemodynamic benefit of CRT and signs of BiVp-fusion by using a novel EGM-based method. METHODS: In 17 patients undergoing CRT implantation, 28 combinations of atrioventricular (AV) and interventricular (VV) delays were applied while invasively measuring acute hemodynamic response based on maximum rate of LV pressure rise (LV dP/dtmax ) to assess optimal BiVp settings...

Accumulating data show that the phenotypes and functions of distinctive mucosal dendritic cells (DCs) in the gut are regulated by retinoic acid (RA). Unfortunately, the exact role of butyrate in RA mediated mucosal DC differentiation has not been thoroughly elucidated to date. Mucosal like dendritic cell differentiation was completed in vitro by culturing bone marrow cells with growth factors (GM-CSF/IL-4), RA and/or butyrate. The phenotypes, cytokine secretion, immune functions and levels of retinal dehydrogenase of different DCs were detected using qPCR, ELISA and flow cytometry, respectively...

BACKGROUND AND PURPOSE: Inward rectifier current (IK1 ) density increases in atrial fibrillation (AF), shortening effective refractory period and thus promotes atrial reentry. Pentamidine-Analogue 6 (PA-6) is a selective and potent IK1 inhibitor. We tested PA-6 for anti-AF efficacy and potential proarrhythmia, in established large animal models. EXPERIMENTAL APPROACH: PA-6 was applied i.v. in anaesthetized goats with rapid pacing induced AF and anaesthetized chronic AV block dogs...

T0001 is a recombinant human TNFR-Fc fusion protein mutant; it exhibits higher affinity to TNFα than etanercept and is now being tested in a Phase 1 study in China (ClinicalTrials.gov Identifier: NCT02481180). T0001 can inhibit the binding of soluble TNFα (sTNFα) or membrane-bound TNFα (mTNFα) to TNF receptors. When bound to mTNFα, the Fc-bearing TNFα antagonists have the potential to induce Fc-mediated effects, such as antibody-dependent cellular cytotoxicity (ADCC) and complement-mediated cytotoxicity (CDC) as well as outside-to-inside signals (apoptosis mainly)...

The risks and complication profile of reverse total shoulder arthroplasty (RSA) in rheumatoid arthritis (RA) patients has yet to be clearly defined as most studies have small cohorts. Using a large inpatient database, the purpose on our study was to determine the overall demographics, hospitalization characteristics, and early complication rates in rheumatoid patients and compared these to rotator-cuff arthropathy patients without RA undergoing RSA. Utilizing United States Nationwide Inpatient Sample from 2010 to 2013, we evaluated a total of 919 RA RSA and compared them to 8097 patients without RA undergoing RSA...

One of the important elements for most bacterial growth is iron, the bioavailability of which is limited in hosts. Riemerella anatipestifer (R. anatipestifer, RA), an important duck pathogen, requires iron to live. However, the genes involved in iron metabolism and the mechanisms of iron transport are largely unknown. Here, we investigated the transcriptomic effects of iron limitation condition on R. anatipestifer CH-1 using the RNA-Seq and RNA-Seq-based analysis. Data analysis revealed genes encoding functions related to iron homeostasis, including a number of putative TonB-dependent receptor systems, a HmuY-like protein-dependent hemin (an iron-containing porphyrin) uptake system, a Feo system, a gene cluster related to starch utilization, and genes encoding hypothetical proteins that were significantly upregulated in response to iron limitation...

OBJECTIVES: The previous studies generated neural progenitor cells (NPCs) from human induced pluripotent stem cells (hiPSCs) using different protocols. However, the nature of the temporal or regional specificity of NPCs derived using these protocols is not well defined. Therefore, this study aimed to generate age- and region-specific NPCs from hiPSCs, which mimic in vivo fetal brain (FNPC-B) or spinal cord (FNPC-SC) tissues, in the absence or presence of retinoic acid (RA) and sonic hedgehog (SHH)...
