Hereditary generalized dystonia is often caused by a GAG deletion in TOR1A (DYT1) that encodes for the protein torsinA. Although mutation carriers show alterations in neuronal connectivity and sensorimotor deficits, only 30% develop dystonia. Uncovering the factors triggering the dystonic symptoms and underlying pathophysiology would greatly benefit the development of more effective therapies. In DYT1 knock-in (KI) mice, the expression of torsinA mutant alters the connectivity of neurons and the function of striatal cholinergic interneurons...

Recent studies have shown that molecular phylogenies of the choanoflagellates (Class Choanoflagellatea) are in disagreement with their traditional taxonomy, based on morphology, and that Choanoflagellatea requires considerable taxonomic revision. Furthermore, phylogenies suggest that the morphological and ecological evolution of the group is more complex than has previously been recognized. Here we address the taxonomy of the major choanoflagellate order Craspedida, by erecting four new genera. The new genera are shown to be morphologically, ecologically and phylogenetically distinct from other choanoflagellate taxa...

Internalization of Staphylococcus aureus by non-professional phagocytic cells is a major suspected cause of persistent and difficult-to-treat infections, including pneumonia. In this study, we established an infection model with 16HBE14o- human bronchial epithelial cells and demonstrated internalization, escape from phagosomal clearance and intracellular replication of S. aureus HG001 within the first four hours post-infection. We used quantitative phosphoproteomics to identify characteristic signaling networks in the host at different infection stages...

The dynamic clinical course of rheumatic conditions indicates a need for regular collection of information on health status to monitor disease activity and functional status. Patient-reported outcomes measures (PROMs) are playing a key role in the evaluation of symptoms and functioning and health, and are crucial in the initiation of treatment in those patients. In recent years, electronic assessments of PROMs (so called ePROMs) have been introduced. This report summarises some of the rationale, opportunities, and results using ePROMs in patients with spondyloarthritis (SpA)...

The study of secondary patient data, particularly represented by claims data, has increased in recent years. The strength of this approach involves easy access to data that have been generated for administrative purposes. By contrast, collection of primary data for research is time-consuming and may therefore appear outdated. Both administrative data and data collected prospectively in clinical care can address similar research questions concerning effectiveness and safety of treatments. Therefore, why should we invest the precious time of rheumatologists to generate primary patient data? This article will outline some features of primary patient data collection illustrated by the German biologics register RABBIT (Rheumatoid arthritis: observation of biologic therapy)...

Electronic health records are increasingly used and frequently required from various regulatory authorities. Apart from their day-to-day use by health care professionals for routine clinical practice and/or the improvement of quality of care processes, patients with chronic inflammatory disease may become increasingly involved in the data retrieval process by self-monitoring and providing patient-reported (outcome) data. Among key features of electronic health records are automated scoring, visualisation of validated measures, and long-term systematic patient-centered data collection in a structured and standardised manner...

Enabling technologies for efficient use of the bio-based feedstock are crucial to the replacement of oil-based products. We investigated the feasibility of luminescent conjugated oligothiophenes (LCOs) for non-destructive, rapid detection and quality assessment of lignocellulosic components in complex biomass matrices. A cationic pentameric oligothiophene denoted p-HTEA (pentamer hydrogen thiophene ethyl amine) showed unique binding affinities to cellulose, lignin, hemicelluloses, and cellulose nanofibrils in crystal, liquid and paper form...

Behavioral profiles are strongly shaped by an individual's whole life experience. The accumulation of negative experiences over lifetime is thought to promote anxiety-like behavior in adulthood ("allostatic load hypothesis"). In contrast, the "mismatch hypothesis" of psychiatric disease suggests that high levels of anxiety-like behavior are the result of a discrepancy between early and late environment. The aim of the present study was to investigate how different life histories shape the expression of anxiety-like behavior and modulate fear memory...

INTRODUCTION: One of the most important complications of orbital floor fractures is diplopia and restricted ocular movement. The role of the volume of soft tissue herniation on these clinical symptoms after orbital floor fractures is unclear and potentially may predict development of persistent clinical symptoms. Therefore the aim of this study was to assess pre- and postoperative complications associated to the volume of soft tissue herniation, with special interest to diplopia and bulbus motility impairment...

Chronic inflammatory conditions during peritoneal dialysis (PD)-treatment lead to the impairment of peritoneal tissue integrity. The resulting structural and functional reorganization of the peritoneal membrane diminishes ultrafiltration rate and thereby enhances mortality by limiting dialysis effectiveness over time. Tumour necrosis factor (TNF) and its receptors TNFR1 and TNFR2 are key players during inflammatory processes. To date, the role of TNFR1 in peritoneal tissue damage during PD-treatment is completely undefined...

Topoisomerase IIα is an essential enzyme that resolves topological constraints in genomic DNA. It functions in disentangling intertwined chromosomes during anaphase leading to chromosome segregation thus preserving genomic stability. Here we describe a previously unrecognized mechanism regulating topoisomerase IIα activity that is dependent on the F-box protein Fbxo28. We find that Fbxo28, an evolutionarily conserved protein, is required for proper mitotic progression. Interfering with Fbxo28 function leads to a delay in metaphase-to-anaphase progression resulting in mitotic defects as lagging chromosomes, multipolar spindles and multinucleation...

OBJECTIVES/HYPOTHESIS: In professional classical singing, an even voice quality throughout the entire singing voice range is essential. Transitions between vocal registers (passaggio) are the technically most challenging aspects in classical singing. It is hypothesized that they are most affected by vocal fold mass lesions (VFML). STUDY DESIGN: Cohort study. METHODS: In this study, the effect of VFML on vocal fold vibration in the passaggio regions was analyzed in four female and three male singers suffering from organic dysphonia...

Fragments of small nucleolar RNAs (snoRNAs) were found among various non-coding RNAs (ncRNAs) circulating in human blood. Currently, the function of such cell-free sno-derived-RNAs is not clearly defined. This work is aimed at identifying regulatory pathways controlled by extracellular snoRNAs. In order to determine the molecular targets and pathways affected by artificial snoRNAs, we performed Illumina array analysis of MCF-7 human adenocarcinoma cells transfected with box C/D RNAs. The genes related to the innate immune response and apoptotic cascades were found to be activated in transfected cells compared with control cells...

Human blood contains a great variety of membrane-covered RNA carrying vesicles which are spherical or tubular particles enclosed by a phospholipid bilayer. Circulating vesicles are thought to mediate cell-to-cell communication and their RNA cargo can act as regulatory molecules. In this work, we separated blood plasma of healthy donors by centrifugation and determined that vesicles precipitated at 16,000 g were enriched with CD41a, marker of platelets. At 160,000 g, the pellets were enriched with CD3 marker of T cells...

BACKGROUND: Residues of veterinary medicinal products (VMPs) enter the environment via application of manure onto agricultural areas where in particular antibiotics can cause phytotoxicity. Terrestrial plant tests according to OECD guideline 208 are part of the environmental risk assessment of VMPs. However, this standard approach might not be appropriate for VMPs which form non-extractable residues or transformation products in manure and manure-amended soil. Therefore, a new test design with a more realistic exposure scenario via manure application is needed...

BACKGROUND: The projected rise in the incidence of type 2 diabetes mellitus (T2DM) could develop into a substantial health problem worldwide. Whether insulin secretagogues (sulphonylureas and meglitinide analogues) are able to prevent or delay T2DM and its associated complications in people at risk for the development of T2DM is unknown. OBJECTIVES: To assess the effects of insulin secretagogues on the prevention or delay of T2DM and its associated complications in people with impaired glucose tolerance, impaired fasting blood glucose, moderately elevated glycosylated haemoglobin A1c (HbA1c) or any combination of these...
