Spatiotemporal Profiling of Protein Kinase A Activity in Spontaneously Beating hiPSC-derived Cardiac Organoids
AbstractProtein kinase A (PKA) phosphorylates proteins crucial for rhythm modulation, with its dysregulation linked to arrhythmias. This study investigated PKA activity’s spatiotemporal dynamics in spontaneously beating cardiac organoids. We hypothesized that PKA activity would respond to autonomic stimulation and exhibit spatial heterogeneity upon drug-induced modulation

Predictors of Complicated Disease Course in Children and Adults With Ulcerative Colitis: A Nationwide Study From the epi-IIRN
AbstractData on predictors of complicated ulcerative colitis (UC) course from unselected populations cohorts are scarce. We aimed to utilize a nationwide cohort to explore predictors at diagnosis of disease course in children and adults with UC.
Data of patients diagnosed with UC since 2005 were retrieved from the nationwide epi-IIRN cohort. Complicated disease course was

Enhancing Retinal Vessel Segmentation Generalization via Layout-Aware Generative Modelling
AbstractGeneralization in medical segmentation models is challenging due to limited annotated datasets and imaging variability. To address this, we propose Retinal Layout-Aware Diffusion (RLAD), a novel diffusion-based framework for generating controllable layout-aware images. RLAD conditions image generation on multiple key layout components extracted from real images, ensuring

Familial Mediterranean fever in patients with inflammatory bowel diseases: a nationwide study from the epi-IIRN
AbstractInflammatory bowel diseases (IBD) and familial Mediterranean fever (FMF) are auto-inflammatory diseases with common clinical and biological features. We aimed to determine their association and characterize the natural history in patients with both diagnoses.
Utilizing data from the epi-IIRN cohort, which includes 98% of Israel's population, we calculated the adjusted

T1-PILOT: Optimized Trajectories for T1 Mapping Acceleration
AbstractCardiac T1 mapping provides critical quantitative insights into myocardial tissue composition, enabling the assessment of pathologies such as fibrosis, inflammation, and edema. However, the inherently dynamic nature of the heart imposes strict limits on acquisition times, making high-resolution T1 mapping a persistent challenge. Compressed sensing (CS) approaches have

GONet: A Generalizable Deep Learning Model for Glaucoma Detection
AbstractGlaucomatous optic neuropathy (GON) is a prevalent ocular disease that can lead to irreversible vision loss if not detected early and treated. The traditional diagnostic approach for GON involves a set of ophthalmic examinations, which are time-consuming and require a visit to an ophthalmologist. Recent deep learning models for automating GON detection from digital

Emulsion-templated macroporous polycaprolactone: Synthesis, degradation, additive manufacturing, and cell-growth
AbstractPolyHIPEs are macroporous polymers templated within high internal phase emulsions (HIPEs). The ability to tailor the macromolecular and porous structures makes polyHIPEs of interest for three dimensional tissue engineering scaffolds. In this work, polyHIPEs with densities ranging from 0.18 to 0.28 g/cc were synthesized from novel biodegradable poly(ɛ-caprolactone)

MBSS-T1: Model-based subject-specific self-supervised motion correction for robust cardiac T1 mapping
AbstractCardiac T1 mapping is a valuable quantitative MRI technique for diagnosing diffuse myocardial diseases. Traditional methods, relying on breath-hold sequences and cardiac triggering based on an ECG signal, face challenges with patient compliance, limiting their effectiveness. Image registration can enable motion-robust cardiac T1 mapping, but inherent intensity differences
