Primary diffuse leptomeningeal atypical teratoid/rhabdoid tumours (ATRT) of childhood: a molecularly characterised case report and literature review.

Background: Atypical teratoid/rhabdoid tumours (ATRTs) are malignant central nervous system tumours, typically presenting in the posterior fossa of very young children. Prognosis remains poor despite current therapy, while tumorigenesis implicates both genomic and epigenetic dysregulation. Primary diffuse leptomeningeal (PDL) ATRT, characterised by the absence of an intraparenchymal mass lesion, is seldom reported but appears associated with a dismal outcome.

Thermoelectric properties of the low-spin lanthanide cobalate perovskites LaCoO, PrCoO, and NdCoO from first-principles calculations.

An modelling workflow is used to predict the thermoelectric properties and figure of merit of the lanthanide cobalates LaCoO, PrCoO and NdCoO in the orthorhombic phase with the low-spin magnetic configuration. The LnCoO show significantly lower lattice thermal conductivity than the widely-studied SrTiO, due to lower phonon velocities, with a large component of the heat transport through an intraband tunnelling mechanism characteristic of amorphous materials. Comparison of the calculations to experimental measurements suggests the p-type electrical properties are significantly degraded by the thermal spin crossover, and materials-engineering strategies to suppress this could yield improved .

Significant Efficiency Enhancements in Non-Y Series Acceptors by the Addition of Outer Side Chains.

Most current highly efficient organic solar cells utilize small molecules like Y6 and its derivatives as electron acceptors in the photoactive layer. In this work, a small molecule acceptor, SC8-IT4F, is developed through outer side chain engineering on the terminal thiophene of a conjugated 6,12-dihydro-dithienoindeno[2,3-d:2',3'-d']-s-indaceno[1,2-b:5,6-b']dithiophene (IDTT) central core. Compared to the reference molecule C8-IT4F, which lacks outer side chains, SC8-IT4F displays notable differences in molecule geometry (as shown by simulations), thermal behavior, single-crystal packing, and film morphology.

Antibodies and Inflammation: Fecal Biomarkers of Gut Health in Domestic Ruminants.

Gastrointestinal infections present major challenges to ruminant livestock systems, and gut health is a key constraint on fitness, welfare, and productivity. Fecal biomarkers present opportunities to monitor animal health without using invasive methods, and with greater resolution compared to observational metrics. Here we developed enzyme-linked immunosorbent assays for three potential fecal biomarkers of gut health in domestic ruminants: two immunological (total immunoglobulin [Ig]A and total IgG) and one inflammatory (lactoferrin).

Recommendations for reporting and evaluating proton therapy beyond dose and constant relative biological effectiveness.

Background And Purpose: In proton therapy, a relative biological effectiveness (RBE) of 1.1 is used to convert proton dose into an equivalent photon dose. However, RBE varies with tissue type, fraction dose, and beam quality parameters beyond dose such as linear energy transfer (LET) raising concerns about increased local effectiveness and potential toxicity.

Through each other's eyes: initial results and protocol for the co-design of an observational measure of adolescent-parent interaction using first-person perspective.

Background: Current observational methods to understand adolescent-parent interaction are limited in terms of ecological and content validity. We outline initial results and a protocol for future work from a programme of work to: (1) establish a new method for data capture of adolescent-parent interaction at home using wearable cameras and; (2) develop a new relevant and comprehensive observational micro-coding scheme. In Part 1, we report our completed preliminary work, comprised of an initial scoping review, and public engagement work.

Toughening of thermoset composites using glass/polypropylene commingled stitching yarns.

This paper investigates the damage resistance and tolerance of thermoset composite laminates stitched by glass and hybrid glass/polypropylene commingled yarns. Different impact energies (10-70 J) were applied to stitched composite laminates before compression after impact (CAI) tests were conducted. The results showed that, except for 70J, commingled yarn-stitched laminates absorbed more energy than glass-stitched laminates.

Meeting report - Alpine desmosome disease meeting 2024: advances and emerging topics in desmosomes and related diseases.

Desmosomes are adhesive cell contacts abundant in tissues exposed to mechanical strain, such as the stratified and simple epithelia of the epidermis and mucous membranes, as well as the myocardium. Besides their role in mechanical cell cohesion, desmosomes also modulate pathways important for tissue differentiation, wound healing and immune responses. Dysfunctional desmosomes, resulting from pathogenic variants in genes encoding desmosomal components, autoantibodies targeting desmosomal adhesion molecules or inflammation, cause the life-threatening diseases arrhythmogenic cardiomyopathy and pemphigus and contribute to the pathogenesis of inflammatory bowel diseases.

'If one doesn't happen, the other will': forensic mental health service patients' experiences of co-occurring self-harm and aggression.

Background: Co-occurring self-harm and aggression (dual harm) is particularly prevalent among forensic mental health service (FMHS) patients. There is limited understanding of why this population engages in dual harm.

Aims: This work aims to explore FMHS patients' experiences of dual harm and how they make sense of this behaviour, with a focus on the role of emotions.

An in silico analysis of heart rate impact on wall shear stress hemodynamic parameters in aortic coarctation.

This study examines how heart rate (HR) affects hemodynamics in a South African infant with Coarctation of the Aorta. Computed tomography angiography segments aortic coarctation anatomy; Doppler echocardiography derives inlet flow waveforms. Simulations occur at 100, 120, and 160 beats per minute, representing reduced, resting, and elevated HR levels.

The Efficacy of 3 Bleaching Methods on Stained Polymer-Based CAD/CAM Materials.

Introduction And Aims: This study aimed to investigate the efficacy of 3 bleaching methods on stained polymer-based CAD/CAM blocks in terms of surface roughness, hardness stability, discolouration reduction and susceptibility to re-staining following bleaching.

Methods: Two-mm-thick slabs (N = 128) were prepared from CeraSmart (CS), Grandio Blocs (GB), Vita Enamic (VE), and direct resin composite GrandioSO (RC). Coffee-stained specimens (n = 8) were subdivided into bleaching (BL) groups: in-office bleaching (OB), home bleaching (HB), whitening mouthwash (MW), and a control group with 14-day storage in water (CL).

Impact of family childhood adversity on risk of violence and involvement with police in adolescence: findings from the UK Millennium Cohort Study.

Background: Childhood adversities, such as exposure to parental mental illness, domestic violence and abuse, substance use, and family poverty, have been linked to involvement in violence in early adulthood. However, evidence on the cumulative impact of multiple adversities throughout childhood on violence and crime in adolescence remains scarce. This study investigates the associations between trajectories of family adversity and poverty during childhood, and the risk of involvement in violence and contact with police in adolescence.

Small cell carcinoma of the ovary, hypercalcaemic type causing an acute kidney injury.

SummaryWe report a case of small cell carcinoma of the ovary, hypercalcaemic type, a rare and aggressive form of ovarian cancer, causing an acute kidney injury. A woman in her mid-30s presented with a large pelvic mass and abdominal distention, this was associated with rapidly deteriorating renal function, which did not improve with standardised kidney injury treatment. There was a high suspicion of ovarian cancer.

The window of opportunity: Estimating the role of climate finance on urban-rural electricity inequality.

Access to electricity is vital for enhancing human welfare; however, it is not equally distributed between rural and urban demographics. This paper, for the first time, examine the impact of climate finance on electricity accessibility, and the inequality of electricity accessibility between urban and rural areas. Based on the dataset covering 125 countries during 2002-2020, and by using the instrumental Variables-Generalized Method of Moments model, we mainly arrive at the following conclusions.

Temperate grassland conversion to conifer forest destabilises mineral soil carbon stocks.

Tree-planting is increasingly presented as a cost-effective strategy to maximise ecosystem carbon (C) storage and thus mitigate climate change. Its success largely depends on the associated response of soil C stocks, where most terrestrial C is stored. Yet, we lack a precise understanding of how soil C stocks develop following tree planting, and particularly how it affects the form in which soil C is stored and its associated stability and resistance to climate change.

Best Practice for Patient-centred Radiotherapy in Clinical Trials and Beyond-A National Multidisciplinary Consensus.

We present a multidisciplinary national consensus with the aim to provide recommendations for best practice in patient-centred radiotherapy for both clinical trials and routine practice.

Optimising Instrumented Mouthguard Data Analysis: Video Synchronisation Using a Cross-correlation Approach.

Purpose: Head acceleration events (HAEs) are a growing concern in contact sports, prompting two rugby governing bodies to mandate instrumented mouthguards (iMGs). This has resulted in an influx of data imposing financial and time constraints. This study presents two computational methods that leverage a dataset of video-coded match events: cross-correlation synchronisation aligns iMG data to a video recording, by providing playback timestamps for each HAE, enabling analysts to locate them in video footage; and post-synchronisation event matching identifies the coded match event (e.

Efficacy and safety of laser interstitial thermal therapy versus radiofrequency ablation and stereotactic radiosurgery in the treatment of intractable mesial temporal lobe epilepsy: a systematic review and meta-analysis.

Epilepsy is a common neurological disease that is treated with medications; however, patients with drug-resistant epilepsy, commonly intractable temporal lobe epilepsy, tend to have better control with surgical treatment. While the mainstay of surgical treatment is anterior temporal lobectomy, it carries risk of potential adverse effects hence minimally invasive techniques are now being used as an alternative to open surgery. This systematic review and meta-analysis compare the efficacy and safety of three of the most used techniques: laser interstitial thermal therapy (LITT), radiofrequency ablation (RFA) and stereotactic radiosurgery (SRS).

Improved Annotation of Asthma Gene Variants with Cell Type Deconvolution of Nasal and Lung Expression-Quantitative Trait Loci.

Asthma is a genetically complex inflammatory airway disease associated with over 200 Single nucleotide polymorphisms (SNPs). However, the functional effects of many asthma-associated SNPs in lung and airway epithelial samples are unknown. Here, we aimed to conduct expression quantitative trait loci (eQTL) analysis using a meta-analysis of nasal and lung samples.

Parents' lived experience of support through their neonate's end of life and grief journey: An interpretative phenomenology study.

Medical and pharmacological advancements have influenced the ability to treat acutely ill neonates. However, complications of prematurity mean that death is unpreventable in some cases. The aim of this study was to explore parents' lived experiences of end of life care and their perceptions of support needs during and following the death of their baby in neonatal intensive care units in the United Kingdom.
