INTRODUCTION: Balance performance in the elderly is related to psychological factors such as attentional focus. We investigated the effects of internal vs. external focus of attention and fall history on walking stability in healthy older adults. METHOD: Walking stability of twenty-eight healthy older adults was assessed by applying random unilateral decelerations on a split-belt treadmill and analysing the resulting balance recovery movements. The internal focus instruction was: concentrate on the movement of your legs, whereas the external focus instruction was: concentrate on the movement of the treadmill...

OBJECTIVES: The impact of the Trauma Collaborative Care (TCC) program on surgeon confidence in managing the psychosocial sequelae of orthopaedic trauma was evaluated as part of a larger prospective, multisite, cluster clinical trial. We compared confidence and perceived resource availability among surgeons practicing in trauma centers that implemented the TCC program with orthopaedic trauma surgeons in similar trauma centers that did not implement the TCC. DESIGN: Prospective cohort design SETTING:: Level 1 Trauma Centers PARTICIPANTS:: Attending surgeons and Fellows...

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder marked by the loss of motor neurons (MNs) in the brain and spinal cord, leading to fatally debilitating weakness. Because this disease predominantly affects MNs, we aimed to characterize the distinct expression profile of that cell type in order to elucidate underlying disease mechanisms and identify novel targets that inform on MN health during ALS disease timecourse. microRNAs (miRNAs) are short, non-coding RNAs that can shape the expression profile of a cell and, consequently, often exhibit cell type enriched expression...

BACKGROUND: Cortical damage after stroke can drastically impair sensory and motor function of the upper limb, affecting the execution of activities of daily living and quality of life. Motor impairment after stroke has been thoroughly studied, however sensory impairment and its relation to movement control has received less attention. Integrity of the somatosensory system is essential for feedback control of human movement, and compromised integrity due to stroke has been linked to sensory impairment...

Using an advanced functional photoresist we introduce direct-laser-written (DLW) 3D microstructures capable of complete degradation on demand. The networks consist exclusively of reversible bonds, formed by irradiation of a phenacyl sulfide linker, giving disulfide bonds in a radical-free step-growth polymerization via a reactive thioaldehyde. The bond formation was verified in solution by ESI-MS. To induce cleavage, dithiothreitol causes a thiol-disulfide exchange, erasing the written structure. The mild cleavage of the disulfide network is highly orthogonal to other, for example, acrylate-based DLW structures...

The metabolism of tryptophan through kynurenine and serotonin pathways is linked to depression. Here, effects of different drugs with antidepressant properties (vortioxetine, fluoxetine and ketamine) on various tryptophan metabolites in different brain regions and plasma were examined using tandem mass spectrometry (LC-MS/MS), in Flinders Sensitive Line (FSL) rats, a genetic rat model of depression, and its controls: Flinders Resistant Line (FRL) and Sprague-Dawley (SD) rats. Protein levels of kynurenine pathway enzymes were measured in the brains and livers of these rat strains...

In super-cooled aqueous solutions, ice nucleation is the initial stage of the freezing process. In this paper, we present experimental results that indicate that during the freezing of aqueous solutions, freeze-induced phase separation (FIPS) into pure ice and a freeze-concentrated solution (FCS) takes place. Our observations involve the use of an optical cryo-microscope (OC-M) to record images and movies. The results visually indicate for the first time that there are two freezing processes for (NH4)3H(SO4)2/H2O solutions: (i) contact freezing, as is the case for pure water drops, and (ii) the Wegener-Bergeron-Findeisen process, which is the growth of frozen drops (ice) at the expense of liquid ones...

INTRODUCTION: Extranodal Natural Killer (NK)/T-cell lymphoma (NKTCL) nasal type is a rare but well-known disease with poor prognosis. NKTCL is more prevalent in Asia and comprises about 7-10% of all non-Hodgkin lymphoma cases in this region. The characteristic clinical pattern of NKTCL is the destruction of the midline structures of the mid-face. CASE REPORT: The present study examines a case of NKTCL in a 23-year-old man with a destructive ulcer of the palate and uvulae...

Tumour necrosis factor alpha (TNFα) is a cytokine that is pivotal in the inflammatory response. Blockade of TNFα has been shown to be effective in a number of human autoimmune diseases, including rheumatoid arthritis, raising the question of whether this approach may be effective in inflammatory kidney disease, such as ANCA-associated vasculitis (AAV). In AAV, there is considerable evidence for the role of TNFα in the pathophysiology of disease, including increased expression of TNFα mRNA in leucocytes and in renal tissue...

Granulomatosis with Polyangiitis (GPA) (formerly known as Wegener's granulomatosis) is a vasculitis of unknown etiology affecting predominantly small- to medium-sized vessels, usually involving the upper and lower respiratory tract and kidneys. Anti-neutrophil cytoplasmic autoantibodies are probably the initial cause of the inflammatory process that leads to the typical necrotizing lesions. In this issue of the European Journal of Immunology, Szczeklik et al. [Eur. J. Immunol. 2017. 47: 724-733] report some interesting findings on the possible involvement of T-cell subsets in the pathogenesis of the disease...

OBJECTIVE: Electroconvulsive therapy (ECT) is one of the most efficient treatments for major depression. Electroconvulsive seizures (ECS), the animal model of ECT, is widely used to study both mechanisms of action and adverse effects of ECT. As the treatment itself serves as an instant anaesthetic and anaesthetic agents may affect memory functions and behaviour, ECS is traditionally administered without muscle relaxation and anaesthesia. A major problem of unmodified ECS, which has only been addressed peripherally in the literature, is that some animals sustain spinal fractures and subsequent hind leg paralysis (paraplegia)...

OBJECTIVE: Human papilloma virus (HPV) induced head and neck squamous cell carcinoma (HNSCC) represents a distinct tumor subset. We questioned how accurately a brushing from the tumor surface detects HPV in patients with HNSCC. MATERIALS AND METHODS: Brushings from the tumor surface were compared with HPV DNA isolation from formalin-fixed and paraffin-embedded (FFPE) tumor biopsies, which served as the reference standard. In both matrices, HPV DNA was detected using a commercially available test kit...

Schizophrenia is a debilitating brain disorder characterized by disturbances of emotion, perception and cognition. Cognitive impairments predict functional outcome in schizophrenia and are detectable even in the prodromal stage of the disorder. However, our understanding of the underlying neurobiology is limited and procognitive treatments remain elusive. We recently demonstrated that mice heterozygous for an inactivated allele of the schizophrenia-associated Brd1 gene (Brd1(+/)(-) mice) display behaviors reminiscent of schizophrenia, including impaired social cognition and long-term memory...

THE bewildering organismal and functional complexity of microbial eukaryotes has long fascinated protistologists but exceeded the capacity of this research community to comprehensively study it. Lacking the critical mass for a strong scientific discipline, protistologists remain largely divided into various sub-communities (protozoology versus phycology, aquatic versus terrestrial systems, fossil versus extant organisms, etc.), many of which are adjuncts of other larger fields that may speak different technical languages or use different taxonomic systems...

PURPOSE: The influence of the Integral Quality Monitor (IQM) transmission detector on photon beam properties was evaluated in a preclinical phase, using data from nine participating centres: (i) the change of beam quality (beam hardening), (ii) the influence on surface dose, and (iii) the attenuation of the IQM detector. METHODS: For 6 different nominal photon energies (4 standard, 2 FFF) and square field sizes from 1×1cm(2) to 20×20cm(2), the effect of IQM on beam quality was assessed from the PDD20,10 values obtained from the percentage dose depth (PDD) curves, measured with and without IQM in the beam path...
