Objectives The aim of this integrated analysis is to evaluate the long-term safety and tolerability of ixekizumab in adults with psoriasis, PsA and axial SpA. Methods Integrated safety data from 21 clinical trials are presented by indication in patients who received at least one dose of ixekizumab. Adverse events (AEs) and treatment-emergent adverse events (TEAEs) adjusted incidence rates (IRs) per 100 patient-years (PY) up to 5 years' exposure are reported. Results A total of 8228 patients with an ixekizumab exposure of 20 895.9 PY were included in this analysis. The most common TEAEs were nasopharyngitis, upper respiratory tract infection and injection-site reactions. Across populations, IRs were low for AEs leading to discontinuation (IRs ≤5.1 per 100 PY), serious AEs (IRs ≤6.0 per 100 PY) and death (IRs ≤0.3 per 100 PY). The most reported TEAEs of special interest were infections (IRs ≤35.8 per 100 PY). Patients rarely reported malignancies (IR ≤0.8), IBD including ulcerative colitis and Crohn's disease (IR ≤0.8) and major adverse cardiovascular events (IR ≤0.5). TEAEs were most commonly reported the first 2 years of exposure with ixekizumab and IR decreased over the years (infections, injection-site reactions and depression) or remained constant over the entire treatment period (serious infections, major adverse cardiovascular events, malignancies and IBD). Conclusion This long-term analysis on the safety of ixekizumab was consistent with previously published reports and did not show any new safety signals. The safety profile and tolerability reported in this integrated analysis remained consistent with the known safety profile for ixekizumab.Objective Sarcopenia has been associated with poor outcomes in various medical and surgical conditions. However, its impact in systemic necrotizing vasculitides (SNV) had never been characterized. We aimed to assess the prevalence, associated factors and prognostic impact of sarcopenia in SNV. Methods Patients with SNV were successively included in a prospective longitudinal study assessing comorbidities. At inclusion, we evaluated sarcopenia by assessing skeletal muscle mass index using DXA and muscle strength using handgrip strength. Vasculitis and treatments-related events were recorded and analysed using Cox models. Results One hundred and twenty patients were included. At inclusion, low handgrip strength ( less then 30 kg for men and 20 kg for women) was identified in 28 (23%) patients, while no patient exhibited low skeletal muscle mass index ( less then 7.23 kg/m2 for men and 5.67 kg/m2 for women). Low handgrip strength was associated with age (P less then 0.0001), type of vasculitis (P =0.01), vasculitis damage index (P =0.01), history of falls (P =0.0002), osteoporosis (P =0.04), low serum albumin (P =0.003) and prealbumin (P =0.0007), high CRP (P =0.001), high FRAX® tool (P =0.002) and low bone mineral density at femoral neck (P =0.0002). After median follow-up of 42 months, low handgrip strength was associated with higher risk of bone fracture [HR 4.25 (1.37-13.2), P =0.01] and serious adverse events [HR 2.80 (1.35-5.81), P =0.006]. Conclusion Handgrip strength is associated in SNV with nutritional status and comorbidities such as bone disease, and seems to predict, as in other medical conditions, the risk of fracture and serious adverse events during follow-up. In contrast, assessment of skeletal muscle mass index in this population remains uncertain.Root meristem activity is the most critical process influencing root development. Although several regulatory factors that regulate meristem activity have been identified in rice, studies on the enhancement of meristem activity in roots are limited. We identified a T-DNA activation tagging line of a zinc-finger homeobox gene, OsZHD2, which has longer seminal and lateral roots due to increased meristem activity. The phenotypes were confirmed in the transgenic plants overexpressing OsZHD2. In addition, the overexpressing plants enhanced grain yield under low nutrient and paddy field conditions. OsZHD2 was preferentially expressed in shoot apical meristem and root tips. Transcriptome analyses and qRT-PCR experiments on roots from the activation tagging line and wild type (WT) showed that genes for ethylene biosynthesis were up-regulated in the activation line. Ethylene levels were higher in the activation lines compared to the WT. ChIP assay results suggested that OsZHD2 induces ethylene biosynthesis by controlling ACS5 directly. Treatment with ACC, an ethylene precursor, induced the expression of DR5 reporter at the root tip and stele, whereas an ethylene biosynthesis inhibitor, AVG, treatment decreased that expression in both WT and OsZHD2 overexpression line. These observations suggest that OsZHD2 enhances root meristem activity by influencing ethylene biosynthesis and, in turn, auxin.Mitoribosome biogenesis is an expensive metabolic process that is essential to maintain cellular respiratory capacity and requires the stoichiometric accumulation of rRNAs and proteins encoded in two distinct genomes. In yeast, the ribosomal protein Var1, alias uS3m, is mitochondrion-encoded. uS3m is a protein universally present in all ribosomes, where it forms part of the small subunit (SSU) mRNA entry channel and plays a pivotal role in ribosome loading onto the mRNA. GX15-070 However, despite its critical functional role, very little is known concerning VAR1 gene expression. Here, we demonstrate that the protein Sov1 is an in bona fide VAR1 mRNA translational activator and additionally interacts with newly synthesized Var1 polypeptide. Moreover, we show that Sov1 assists the late steps of mtSSU biogenesis involving the incorporation of Var1, an event necessary for uS14 and mS46 assembly. Notably, we have uncovered a translational regulatory mechanism by which Sov1 fine-tunes Var1 synthesis with its assembly into the mitoribosome.This work seeks to remedy two deficiencies in the current nucleic acid nanotechnology software environment the lack of both a fast and user-friendly visualization tool and a standard for structural analyses of simulated systems. We introduce here oxView, a web browser-based visualizer that can load structures with over 1 million nucleotides, create videos from simulation trajectories, and allow users to perform basic edits to DNA and RNA designs. We additionally introduce open-source software tools for extracting common structural parameters to characterize large DNA/RNA nanostructures simulated using the coarse-grained modeling tool, oxDNA, which has grown in popularity in recent years and is frequently used to prototype new nucleic acid nanostructural designs, model biophysics of DNA/RNA processes, and rationalize experimental results. The newly introduced software tools facilitate the computational characterization of DNA/RNA designs by providing multiple analysis scripts, including mean structures and structure flexibility characterization, hydrogen bond fraying, and interduplex angles.
