Resolving Hidden Stoichiometriesin Bacterial ProteasomeActivator (Bpa)-Substrate Complexes by Cryo-EM and Charge DetectionMass Spectrometry

Abstract Bacterial proteasome activator (Bpa) is a regulatory particle within the Mycobacterium tuberculosis (Mtb) proteasome system that facilitates ATP-independent substrate engagement and delivery to the 20S core particle (CP) for degradation. The best characterized Bpa substr...

Building a Physics-Aware AI Ecosystem for Solid-State Hydrogen Storage Materials

Abstract Hydrogen storage remains a central bottleneck for scalable hydrogen energy systems due to the multiscale and coupled nature of the thermodynamics, kinetics, and microstructural evolution of hydrogen storage materials (HSMs). Although artificial intelligence (AI) has acce...

A process evaluation of a randomized clinical trial of selective decontamination of the digestive tract in ventilated adults admitted to intensive care: the SuDDICU PE study

The SuDDICU trial evaluated the effectiveness of selective digestive decontamination (SDD), a prophylactic antibiotic regimen comprising oral, gastric and intravenous (IV) components in ventilated adults admitted to intensive care. The trial recruited 9289 participants in 26 clus...

Considerations for optimal team-based rheumatology care: a qualitative study exploring the experiences of rheumatology health professionals

Interdisciplinary team-based rheumatology care models are a promising solution for improving access to high quality, equitable care for people with rheumatic and musculoskeletal disorders. There is limited understanding on health professionals’ perspectives on their needs to deli...

Mesenchymal stromal cells immunosuppress osteoarthritis synovial fluid modulated monocytes via IL-6 and CCL2

Abstract Mesenchymal stromal cell (MSC) interactions with monocytes/macrophages are central to their therapeutic effects in knee osteoarthritis (KOA); however, mechanisms of these interactions are not fully understood. We hypothesize that MSC soluble factors, particularly interle...

CAR T Cells Targeting an Intracellular Leukemia Antigen Promiscuously Presented by Diverse HLA-II Alleles

Chimeric antigen receptor (CAR) technology has revolutionized B-cell malignancy treatment by enabling T cells to effectively recognize and target lineage-specific surface antigens. However, CAR T cells show limited efficacy against myeloid neoplasms and solid tumors due to challe...

Wnt Pathway Agonism as a Therapeutic Strategy for Retinal Vascular Diseases: A Narrative Review of Evidence to Date

Breakdown of the blood–retinal barrier (BRB) is implicated in many blinding retinal diseases, including diabetic macular edema, neovascular age-related macular degeneration, and retinal vein occlusion. Anti-vascular endothelial growth factor (anti-VEGF) therapies or laser photoco...

Progressive Convex Hull Simplification

Abstract Convex hulls are useful as tight bounding proxies for a variety of tasks including collision detection, ray intersection, and distance computation. Unfortunately, the complexity of polyhedral convex hulls grows linearly with their input. We consider the problem of conser...

Focal Therapy for Prostate Cancer

This retrospective study uses data from the National Cancer Database to examine patterns and temporal trends in use of focal therapy for prostate cancer in US cancer centers; characterize inappropriate use in low-, high-, or very–high-risk disease; and describe intermediate-risk...

Maintenance therapy after allogeneic stem cell transplantation for relapse prevention in myeloid malignancies

Purpose of review Relapse remains the leading cause of treatment failure after allogeneic hematopoietic cell transplantation (HCT) for acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), and outcomes after relapse are poor. This review summarizes and critically appr...

The practical impact of numerical variability on structural MRI measures of Parkinson’s disease

Abstract Numerical variability is rarely quantified in neuroimaging despite many measures relying on subtle morphometric differences across individuals. We instrumented FreeSurfer 7.3.1, a widely used neuroimaging pipeline, to simulate numerical differences across computational e...

MetaboSense: An Integrated Quantum Dot‐Mediated Aptamer Assay and Modular Microfluidic Platform for Continuous In‐Line Monitoring of Lung Metabolism During Ex Vivo Perfusion

ABSTRACT Organ transplantation provides a life‐saving intervention for patients with end‐stage lung disease; however, access to this treatment remains limited by the shortage of donor organs. Ex vivo lung perfusion (EVLP) is a platform that enables surgeons to assess extended‐cri...

Altered Complement and Tubular Mitochondrial Proteins Are Linked to Graft Loss in DSA+ Antibody–Mediated Rejection

Background: Antibody-mediated rejection (AMR) is the main driver of late kidney allograft loss. Anti-HLA donor-specific antibodies (DSA) are strongly associated with AMR. However, 30-60% of DSA + patients do not develop AMR, raising the possibility of local tissue adaptations to...

Bullying victimization, language proficiency, and school belonging among Syrian refugee early adolescents in Canada: A cross‐lagged and random‐intercept cross‐lagged panel study

Abstract Refugee children's school adjustment is often associated with host country language proficiency, peer victimization, and school belonging, but longitudinal associations among these constructs may reflect both stable child differences and time‐varying school‐experience pr...

Resilience and Protective Factors for Mental Health among Indigenous Youth in Canada: A Scoping Review

Abstract Indigenous youth’s inherent strength and resilience play a vital role in their well-being and mental health. Protective factors, closely linked to resilience, spanning individual, family, and community levels reinforce positive mental health outcomes. The purpose of the...

Characterizing Canadian Out-of-district Political Donations from 2015 to 2024

Federal political representation in Canada is geographical: one Member of Parliament (MP) represents one electoral district. Despite this representational structure, Canadians can legally donate to a host of political entities, regardless of proximity. Using a public dataset from...

Generative AI for Hospital Cybersecurity: A Framework for Evaluating Large Language Models for Planning, Threat Detection, and Incident Response

The increasing digitization of healthcare records and growing reliance on interconnected systems have increased hospitals’ exposure to cyber threats, including ransomware, brute-force attacks, and Structured Query Language (SQL) injection. Traditional cybersecurity approaches alo...

Data-driven mapping of known and novel fluid biomarker progression profiles in genetic frontotemporal lobar degeneration

Abstract Introduction Recent proteomic studies have identified both established and novel proteins in genetic frontotemporal lobar degeneration (FTLD). However, it remains unclear at what point in the disease these proteins deviate from normal levels and how their trajectories re...

Hospitalization of Children in Foster Homes: A Canadian Cohort Study

BACKGROUND AND OBJECTIVES: In Canada, approximately 4% to 7% of children live in a foster home during their childhood. This study reports on hospitalizations of children in foster homes, with the hypothesis that rates of hospitalization are higher for children with foster home ex...

Machine learning for early prediction of preterm birth

Abstract Background Preterm birth (PTB), defined as delivery before 37 completed weeks of gestation, remains a major cause of neonatal mortality and long-term morbidity worldwide. Conventional risk assessment strategies, including cervical length measurement and biomarker-based s...
