The phenotypes are associated with greater myelin thickness, higher number of myelinated small diameter axons without an increase in the number of mature OL. The expression of the rate-limiting enzyme of cholesterol biosynthesis (HMGCR) is increased in white matter tracts of the FusOL cKO and results in higher cholesterol content. In addition, phosphorylation of Akt, an important regulator of myelination is increased in the FusOL cKO. Collectively, this work has uncovered a novel role of oligodendrocytic Fus in regulating myelin deposition through activation of Akt and cholesterol biosynthesis. © 2020 Wiley Periodicals, Inc.Currently, the phase transition of aqueous binary systems containing thermoresponsive (co)polymers, and exhibiting upper critical solution temperature (UCST), is exclusively investigated in dilute solutions, which can limit the knowledge of their UCST-type phase transition. Herein, a photo-RAFT polymerization approach, using acrylamide (AAm) and acrylonitrile (AN) as monomer models, is used to prepare well-controlled poly(AAm-co-AN) copolymers "in situ" in highly concentrated dispersions (60 wt%). The impact of the copolymer concentration and the chemical composition (as a variation of AN fraction in the copolymers) on the cloud point temperature (TCP ) are investigated using turbidity measurements. Importantly, the results show that upon increasing the polymer concentration, a sharp increase of TCP up to a maximum point is observed, representing the UCST, before the decrease of TCP at higher polymer concentrations. Finally, a model equation is developed to fit the UCST values of poly(AAm-co-AN), which can be useful to design new poly(AAm-co-AN) copolymers with a desired UCST for a specific application. © 2020 WILEY-VCH Verlag GmbH & Co.

Social determinants of health (SDH) such as socioeconomic disadvantage and geographic isolation increase drowning risk. Swimming and water safety lessons, in part, have reduced drowning in children, while also enabling healthy aquatic participation. Research suggests some Australian children receive insufficient swimming and water safety education and are not achieving essential skills. METHODS A cross-sectional retrospective analysis of swimming and water safety skills achieved by a cohort of children (5 - 12 years) attending commercial swimming lessons in three Australian states was undertaken. Variables included participant demographics (age, gender, and the SDH of socioeconomic status [SES], and geographical remoteness) and skills being taught and achieved. Skills achieved were analysed against the National Swimming & Water Safety Framework and the National Benchmark. RESULTS Swim schools were more likely to teach freestyle (87%) and backstroke (83%); and less likely to teach water safety skills like treading water (53%), and survival backstroke (46%). Overall, 40% of 12 year old children failed to achieve the National Benchmark of 50 metres freestyle, fewer were achieving minimum water safety skills. Children from low socioeconomic areas and regional locations were less likely to be achieving 50 metres freestyle. Children in this study were commonly from major cities (94%) and of high socioeconomic areas (53%). CONCLUSIONS Swimming lessons must incorporate a broad range of swimming and water safety competencies to ensure children have the skills required to reduce drowning, especially for those deemed at increased risk. Linrodostat purchase SO WHAT Stakeholders must prioritise holistic drowning prevention education strategies, ensuring all children can access swimming and water safety programs regardless of their socioeconomic status or geographical location.

However, previous investigations of functional and mechanical adaptation have been contradictory. A lack of clarity in subjects' athletic performance level may have contributed to these disparate findings. This study aimed to describe structural, functional and mechanical characteristics of the cyclists' LV, based on clearly defined performance levels. Male elite cyclists (EC) (n=69), sub-elite cyclists (SEC) (n=30), and non-athletes (NA) (n=46), were comparatively studied using conventional and speckle tracking 2D echocardiography. Dilated eccentric hypertrophy was common in EC (34.7 %), but not SEC (3.3 %). Chamber concentricity was higher in EC compared to SEC (7.11±1.08 g/(ml)2/3 vs 5.85±0.98 g/(ml)2/3 , P less then 0.001). Ejection fraction (EF) was lower in EC compared to NA (57±5 % vs 59±4 %, P less then 0.05), and reduced EF was observed in a greater proportion of EC (11.6 %) compared to SEC (6.7 %). Global circumferential strain (GCε) was greater in EC (-18.4±2.4 %) and SEC (-19.8±2.7 %) compared to NA (-17.2±2.6 %) (P less then 0.05 and P less then 0.001). Early diastolic filling was lower in EC compared to SEC (0.72±0.14 cm/s vs 0.88±0.12 cm/s, P less then 0.001), as were septal E' (12±2 cm/s vs 15±2 cm/s, P less then 0.001) and lateral E' (18±4 cm/s vs 20±4 cm/s, P less then 0.05). The magnitude of LV structural adaptation was far greater in EC compared to SEC. Increased GCε may represent a compensatory mechanism to maintain stroke volume in the presence of increased chamber volume. Decreased E and E' velocities may be indicative of a considerable functional reserve in EC. This article is protected by copyright.

Considerable efforts have been devoted to the investigation of catalysts for graphene growth by chemical vapor deposition in recent years. However, the research on precursors has been hardly accomplished because of the lack of innovation in controllable feeding method. Herein, we present a novel sustained and controlled release approach, and develop a convenient, safe, and potentially scalable feeding system with the assistance of matrix materials and a simple portable feeder. As a result, a highly volatile liquid precursor can be accurately fed to grow large-area, uniform graphene films with optimal properties. This feeding approach will further benefit the synthesis of other two-dimensional materials from various precursors. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
