    Spatiotemporal Profiling of Protein Kinase A Activity in Spontaneously Beating hiPSC-derived Cardiac Organoids

    Abstract

    Protein 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

    Method Device and System for Monitoring Sub-Clincal Progression and Regression of Heart Failure

    Amir Landesberg, Yakov Tsibulsky, Shmuel Rispler
    Abstract

    A method including sensing local accelerations or changes in sensor position, including orientation and displacement, with a local acceleration sensor mounted on a chest or abdomen of a patient, and calculating energy of polyphasic motions, based on sensed information of the local acceleration sensor and classifying severity of cardiac decompensation by calculating an

    Abstract

    Data 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

    Jonathan Fhima, Jan Van Eijgen, Lennert Beeckmans, Thomas Jacobs, Moti Freiman, Luis Filipe Nakayama, Ingeborg Stalmans, Chaim Baskin, Joachim Behar
    Abstract

    Generalization 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

    Michal Kori, Rachel Buchuk, Ofra Goldzweig, Yiska Loewenberg Weisband, Noa Tal, Amir Ben-Tov, Natan Ledderman, Eran Matz, Moti Freiman, Iris Dotan, Dan Turner, Dror S Shouval
    Abstract

    Inflammatory 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

    Abstract

    Cardiac 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

    Or Abramovich, Hadas Pizem, Jonathan Fhima, Eran Berkowitz, Ben Gofrit, Meishar Meisel, Meital Baskin, Jan Van Eijgen, Ingeborg Stalmans, Eytan Z Blumenthal, Joachim Behar
    Abstract

    Glaucomatous 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

    Abstract

    PolyHIPEs 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

    Abstract

    Cardiac 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
