Development of Electroconductive Polypyrrole‐Polycaprolactone and Poly(3,4‐Ethylenedioxythiophene)‐poly(Styrenesulfonate)‐Polyethylene Oxide Fibrous Scaffolds by Pressurised Gyration for Cardiac Tissue Engineering Applications

Macromolecular Materials and Engineering, EarlyView.
This study pioneers the fabrication of electroconductive cardiac scaffolds using pressurised gyration with the conductive polymers PPy and PEDOT:PSS. The resulting scaffolds exhibit optimal electroconductive and physicochemical properties, closely matching those of native cardiac tissue.

Deep learning framework for interpretable quality control of echocardiography video

Medical Physics, EarlyView.
Abstract Background Echocardiography (echo) has become an indispensable tool in modern cardiology, offering real‐time imaging that helps clinicians evaluate heart function and identify abnormalities. Despite these advantages, the acquisition of high‐quality echo is time‐consuming, labor‐intensive, and highly subjective.

Dynamic glucose enhanced imaging using direct water saturation

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Dynamic glucose enhanced (DGE) MRI studies employ CEST or spin lock (CESL) to study glucose uptake. Currently, these methods are hampered by low effect size and sensitivity to motion. To overcome this, we propose to utilize exchange‐based linewidth (LW) broadening of the direct water saturation (DS) curve of the water saturation ...

Nonlinear control of a hybrid pneumo‐hydraulic mock circuit of the cardiovascular system

International Journal of Robust and Nonlinear Control, EarlyView.
Abstract Hybrid cardiovascular mock circuits (HMC), designed for dynamic testing of Ventricular Assist Devices (VAD), offer physiologic accuracy by sequestering model complexity in silico and ease of construction by reducing number of model elements in vitro.

Volumetric Nanodroplet‐Enhanced Ultrasound Surgery Combined with Immune Checkpoint Inhibition as a Cancer Therapy Platform

Small, EarlyView.
This study presents a cancer therapy platform combining nanodroplet‐mediated histotripsy with anti PD‐1 checkpoint inhibition. Activated nanodroplets induce tumor fractionation via low‐frequency ultrasound application, enhancing immune cell infiltration and creating a T‐cell–inflamed microenvironment.

ECG‐TransCovNet: A hybrid transformer model for accurate arrhythmia detection using Electrocardiogram signals

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Abnormalities in the heart's rhythm, known as arrhythmias, pose a significant threat to global health, often leading to severe cardiac conditions and sudden cardiac deaths. Therefore, early and accurate detection of arrhythmias is crucial for timely intervention and potentially life‐saving treatment.

Clinical effects of combination therapy with continuous renal replacement therapy and continuous intravenous sodium infusion therapy

Therapeutic Apheresis and Dialysis, EarlyView.
Abstract Introduction This single‐center retrospective study investigated the clinical effects of combination therapy involving continuous renal replacement therapy (CRRT) and continuous intravenous sodium infusion therapy (cIVNa) in critically ill patients with prerenal acute kidney injury (AKI) who were expected to experience insufficient plasma ...

Muscle Mitochondrial Respiration and Cardiorespiratory Fitness Contribute to Slower Walking Speed of Older Individuals Who Identify as Black

Aging Cell, EarlyView.
While the etiology of race differences in mobility is multifactorial, our data indicate that muscle mitochondrial respiration and cardiorespiratory fitness may contribute to the slower walking speed of individuals who identify as Black compared to White.

Aerobic Exercise Restores Hippocampal Neurogenesis and Cognitive Function by Decreasing Microglia Inflammasome Formation Through Irisin/NLRP3 Pathway

Aging Cell, EarlyView.
Exercise improved PD pathology and memory by reducing microglial inflammation, apoptosis, and the formation of the NLRP3 inflammasome via irisin signaling. Irisin administration partially replicated the beneficial effects of exercise on PD pathology.
