Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare autosomal dominant genetic disorder of heterotopic ossification (HO) characterized by skeletal anomalies and episodic soft tissue swelling (flare-ups) that can transform into heterotopic bone. The progressive development of heterotopic bone and progressive arthropathy leads to significant limitation of mobility. This paper will review various imaging modalities used in evaluating episodic soft tissue swelling (flare-ups), heterotopic bone and skeletal anomalies...

PURPOSE/BACKGROUND: D-cycloserine (DCS) is a partial N-methyl-D-aspartate receptor agonist that potentially augments response to exposure therapy in anxiety disorders by enhancing extinction learning. This randomized, double-blinded, placebo-controlled augmentation trial examined (1) the effectiveness of adding 125 mg of DCS to exposure therapy (before or directly after the first 6 treatment sessions) in patients with panic disorder with agoraphobia and (2) the effectiveness of DCS augmentation preceding exposure relative to DCS augmentation directly postexposure...

A Very Early Rehabilitation Trial (AVERT) was a Phase 3 randomized trial with over 2100 subjects post stroke that had unexpected results with better outcomes for usual care than those receiving very early mobilization. This review of published stroke clinical practice guidelines highlights that recommendations for mobilization have changed after publication of AVERT but also that developers have struggled to provide recommendations for appropriate dose, duration and intensity of mobilization in the acute post stroke period with available analyses from AVERT and other literature...

First metal-shrouded two-dimensional semicon-ductor, single-layer Tl2O, is discussed from first-principles. It is thermally and dynamically stable, has a low cleavage energy call-ing for exfoliation from layered Tl2O bulk, and a very small inter-face mismatch compared to (001) Tl metal. Single-layer Tl2O ex-hibits a direct band gap of 1.56 eV and a very high charge carrier mobility of 4.3×103 cm2 V-1 s-1. The metal-shrouded 2D semicon-ductor promises interesting applications in 2D electronics. An in-triguing layer-thickness dependent direct-to-indirect bandgap tran-sition is observed, and contrary to early literature, the bulk is also a semiconductor...

BACKGROUND: The stool color card has been the primary tool for identifying acholic stools in infants with biliary atresia (BA), in several countries. However, BA stools are not always acholic, as obliteration of the bile duct occurs gradually. This study aims to introduce Baby Poop (Baby unchi in Japanese), a free iPhone application, employing a detection algorithm to capture subtle differences in colors, even with non-acholic BA stools. METHODS: The application is designed for use by caregivers of infants aged approximately 2 weeks-1 month...

INTRODUCTION: The concept of a dual mobility (DM) cup has been in existence for more than 40 years and was initially popularized in Europe. Only recently has it started to garner attention in the United States. Its design, consisting of a small femoral head articulating within a larger polyethylene (PE) insert, which articulates with an outer shell, has found increasing use in patients that are at risk for post-operative dislocations. This case report describes a case of recurrent total hip arthroplasty (THA) dislocation managed with the implantation of a DM cup with an acute intraprosthetic dislocation of the DM construct...

Decreased skeletal muscle performance with increasing age is strongly associated with reduced mobility and quality of life. Increased physical activity is a widely prescribed method of reducing the detrimental effects of ageing on skeletal muscle contractility. The present study uses isometric and work loop testing protocols to uniquely investigate the effects of 8 weeks of voluntary wheel running on the contractile performance of isolated dynapenic soleus and diaphragm muscles of 38 week old CD1 mice. When compared to untrained controls, voluntary wheel running induced significant improvements in maximal isometric stress and work loop power, a reduced resistance to fatigue, but greater cumulative work during fatiguing work loop contractions in isolated muscle...

This research, for the first time, obtained and reported three novel Form I, Form II, and Form III of 20(R)-25-methoxyl-dammarane-3β,12β,20-triol polymorphs, which were distinguished by PXRD, IR, DSC, and SEM. This study firstly exploited a rapid and feasible UHPLC-ESI-MS/MS method to determine plasma levels of 20(R)-25-OCH3-PPD within 4.5min. The composition of mobile phase was acetonitrile and 5mM ammonium acetate water (85:15, v/v) at a flow rate of 0.2mL/min on the BEH C18 Column (2.1mm×50mm, 1.7μm)...

Several non-radioactive methods have widely been utilized to detect antigen-specific cytotoxic T lymphocyte (CTL) responses instead of the classical (51)Cr-release assay. These methods include intracellular cytokine staining, major histocompatibility complex-class I tetramers, and the CD107a mobilization assay. However, they do not directly measure target-cell death. In contrast, several attempts have been made to develop the flow cytometric CTL (FC-CTL) assay for evaluation of cytotoxicity. However, further improvement is necessary for it to become standardized...

BACKGROUND: Metastasis accounts for the most lethal reason for the death of ovarian cancer patients, but remains largely untreated. Epithelial-mesenchymal transition (EMT) is critical for the conversion of early-stage ovarian tumours into metastatic malignancies. Thus the exploration of the signalling pathways promoting EMT would open potential opportunities for the treatment of metastatic ovarian cancer. Herein, the putative role of MDM2 in regulating EMT and metastasis of ovarian cancer SKOV3 cells was investigated...

The assistive equipment provision process is routinely carried out with patients to mitigate fall risk factors via the fitment of assistive equipment within the home. However, currently, over 50% of assistive equipment is abandoned by the patients due to poor fit between the patient and the assistive equipment. This paper explores clinician perceptions of an early stage three-dimensional measurement aid prototype, which provides enhanced assistive equipment provision process guidance to clinicians. Ten occupational therapists trialled the three-dimensional measurement aid prototype application; think-aloud and semi-structured interview data was collected...

Age-related macular degeneration (AMD), a leading contributor of vision loss, currently lacks comprehensive treatment. While AMD histopathology involves retinal pigment epithelium (RPE) injury associated with immune cell infiltration, the nature of immune cell responses to RPE injury remains undefined. We induced RPE injury pharmacologically and genetically in transgenic mouse models in which microglia and systemic monocytes were separately tagged, enabling a spatial and temporal dissection of the relative contributions of microglia vs...

BACKGROUND: Palliative care patients are a particularly vulnerable population and one of the critical phases in patients' trajectories is discharge from specialized in-patient palliative care into outpatient care, where availability of a palliative care infrastructure is highly variable. A relevant number of potentially avoidable readmissions and emergency visits of palliative patients is observed due to rapid exacerbation of symptoms indicating the need for a closer patient monitoring...

Loss-of-function mutations in SCN1A cause Dravet syndrome (DS), a catastrophic childhood epilepsy in which patients experience comorbid behavioral conditions, including movement disorders, sleep abnormalities, anxiety, and intellectual disability. To study the functional consequences of voltage-gated sodium channel mutations, we use zebrafish with a loss-of-function mutation in scn1lab, a zebrafish homolog of human SCN1A. Homozygous scn1lab(s552/s552) mutants exhibit early-life seizures, metabolic deficits, and early death...

Ice-albedo feedback due to the albedo contrast between water and ice is a major factor in seasonal sea ice retreat, and has received increasing attention with the Arctic Ocean shifting to a seasonal ice cover. However, quantitative evaluation of such feedbacks is still insufficient. Here we provide quantitative evidence that heat input through the open water fraction is the primary driver of seasonal and interannual variations in Arctic sea ice retreat. Analyses of satellite data (1979-2014) and a simplified ice-upper ocean coupled model reveal that divergent ice motion in the early melt season triggers large-scale feedback which subsequently amplifies summer sea ice anomalies...

Recent research by Chetty and colleagues finds that children's chances of upward mobility are affected by the communities in which they grow up [Chetty R, Hendren N (2016) Working paper 23002]. However, the developmental pathways through which communities of origin translate into future economic gain are not well understood. In this paper we examine the association between Chetty and Hendren's county-level measure of intergenerational mobility and children's cognitive and behavioral development. Focusing on children from low-income families, we find that growing up in a county with high upward mobility is associated with fewer externalizing behavioral problems by age 3 years and with substantial gains in cognitive test scores between ages 3 and 9 years...

Older adults are increasingly important to maintaining stable workforces. As such, factors contributing to early workforce exit must be identified. This study aimed to identify predictors of unexpected retirement and unemployment at older age, with respect to psychological constructs, resulting adverse behaviors, and health-related factors reflecting functional status. Data were extracted from The Irish Longitudinal Study on Ageing (TILDA) to predict unexpected retirement and unemployment in older adults in Ireland...
