Background: Research priorities guide research activities, funding and resources within health services. To ensure that research efforts are meaningful and impactful, it is vital that organisational research agendas reflect the priorities of both healthcare consumers and staff, alongside broader national and international research frameworks. This paper outlines a research priority-setting project conducted across two hospitals in Western Australia, aimed at identifying shared research priorities through a collaborative and inclusive approach.

It is not known how selective pressures shape the numbers of interconnected neurons in defined neural circuits during the phylogeny of mammals. Consequently, models of function are without phylogenetic bounds, and species differences in neuronal makeup cannot be linked to ecological factors that generate selective pressures. Based on data from 65 species belonging to 11 orders, we here provide an analysis of five interconnected neuron populations in the circuitry of the hippocampus, the forebrain region encoding episodic memories.

Background And Purpose: Patients with amyotrophic lateral sclerosis (ALS) are prescribed many medications for symptomatic relief. However, how potential alterations to the blood-brain barrier (BBB) affect the brain exposure of drugs in ALS remains under-investigated.

Experimental Approach: We used high-dimensional proteomic analysis, cellular metabolism, and mitochondrial functional assays to characterise isolated brain microvascular endothelial cells (BMECs) from wildtype and SOD1 transgenic mice, a mouse model of familial ALS, at a late-symptomatic age (P115-120), together with a transcardiac brain perfusion technique to assess BBB function in situ.

Background: Modified constraint-induced movement therapy (mCIMT) improves upper limb (UL) function after stroke. Despite extensive evidence supporting its efficacy and multiple clinical practice guidelines recommending its provision, very few eligible stroke survivors receive mCIMT internationally. A multi-modal behaviour change intervention, guided by the Theoretical Domains Framework (TDF) and Behaviour Change Wheel, was implemented across a large early-supported discharge (ESD) rehabilitation service in Perth, Australia, to increase delivery of mCIMT within existing resources.

Degeneration of both upper motor neurons in the brain and lower motor neurons in the spinal cord defines amyotrophic lateral sclerosis (ALS), but how they are linked in ALS pathophysiology is unclear. Here, we uncover a cortical origin of neurodegeneration in ALS mediated by upper motor neuron hyperexcitability. Chronic hyperexcitability of upper motor neurons induced by excitatory chemogenetics in healthy adult mice induced progressive motor deficits, weakness and core pathological hallmarks of ALS, including upper motor neurons loss, synaptic pathology, corticospinal tract degeneration and reactive gliosis.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder presenting progressive weakness of the bulbar and extremity muscles, leading to a wide-ranging clinical phenotype. More than 30 genes have been associated to genetically inherited ALS yet, approximately 85%-90% of ALS cases are sporadic. Short tandem repeats expansions, have recently been found in clinically diagnosed ALS patients and are currently investigated as potential genetic biomarkers.

Duplications of one or more dystrophin exons that disrupt the reading frame account for about 15% of all Duchenne cases, and like the more common genomic deletions, most pathogenic duplications of single or multiple dystrophin exons are also amenable to targeted exon skipping. However, additional considerations must be taken into account: (i) Skipping of all duplicated exons, and flanking exons as necessary, will frequently be required to restore the reading frame and generate an in-frame Becker muscular dystrophy-like mRNA, (ii) the phosphorodiamidate morpholino oligomer chemistry is more effective than the 2'-O-methyl modified oligonucleotides at inducing multiple exon skipping, and (iii) the apparent efficiency of exon skipping can be confounded by the choice of RT-PCR system. Standard RT-PCR systems can preferentially amplify the shorter amplicons, implying more efficient exon skipping than may actually be induced.

Early prediction of disability progression in multiple sclerosis (MS) remains challenging despite its critical importance for therapeutic decision-making. We present the first systematic evaluation of personalized federated learning (PFL) for 2-year MS disability progression prediction, leveraging multi-center real-world data from over 26,000 patients. While conventional federated learning (FL) enables privacy-aware collaborative modeling, it remains vulnerable to institutional data heterogeneity.

Background And Objectives: Although disease-modifying therapies (DMTs) may suppress coronavirus disease 2019 (COVID-19) vaccine responses in people with multiple sclerosis (pwMS), limited data are available on the cumulative effect of additional boosters. Maturation of Spike immunoglobulin G (IgG) to target a greater diversity of SARS-CoV-2 variants, especially past the BA.1 variant, has not been reported.

Background: Osteoporosis and dementia are two common disorders mainly affecting ageing population, and heel estimated bone mineral density (eBMD) measured by quantitative ultrasound (QUS) has been demonstrated to be a reliable and non-invasive method for assessing skeletal health. The aim of this study is to determine the association between eBMD and incident dementia in older adults.

Methods: This retrospective cohort study employs UK Biobank data of 131,030 adults aged ≥ 60 years without dementia at baseline.

Mechanotransduction is essential for living cells to adapt to their extracellular environment. However, it is unclear how the biophysical adaptation of intracellular organelles responds to mechanical stress or how these adaptive changes affect cellular homeostasis. Here, using the tendon cell as a mechanosensitive cell type within a bioreactor, we show that the tension of the plasma membrane (PM) and the endoplasmic reticulum (ER) adaptively increases in response to repetitive external stimuli.

Autoantibodies targeting cytosolic 5'-nucleotidase 1A (cN1A) are found in several autoimmune diseases, including inclusion body myositis (IBM), Sjögren's syndrome, and systemic lupus erythematosus. While they have diagnostic relevance for IBM, little is known about the autoreactive B cells that produce these antibodies. To address this, we developed a robust protocol for the expression and site-specific biotinylation of recombinant human cN1A in .

Background: Mobility impairments are common in persons with multiple sclerosis (MS), reducing independence and quality of life. Walking interventions can enhance mobility skills, with auditory-motor coupling (synchronising steps with auditory beats) serving as a promising method. Design and participants' characteristics may impact intervention effectiveness, but have not yet been compared across studies in persons with MS.

An individual's genetics contributes to their risk of developing amyotrophic lateral sclerosis (ALS); however, there is still a large proportion of the heritability of ALS to be understood. Part of this missing heritability may lie in complex variants, such as the long interspersed element 1 (L1) retrotransposon, which have yet to be evaluated. The majority of L1 insertions in the human genome are no longer able to retrotranspose, but to date 279 retrotransposition-competent (RC) L1s have been reported.

Background: Parkinson's disease (PD) is a chronic progressive neurodegenerative disease with debilitating clinical presentations. Common therapeutic approaches for symptomatic improvement are often effective for a temporary period of time, after which patients often experience progressive disabilities. Cell replacement therapy is a potential therapeutic method that aims to replace depleted mesencephalic dopaminergic (DA) neurons, which may control symptoms and halt disease progression.

The fatal neurodegenerative disease, amyotrophic lateral sclerosis (ALS), leads to the degeneration of motor neurons in the brain and spinal cord. Many different genetic variants are known to increase the risk of developing ALS, however much of the disease heritability is still to be identified. To identify novel genetic factors, we characterised SINE-VNTR-Alu (SVA) presence/absence variation in 4403 genomes from the New York Genome Center (NYGC) ALS consortium.
