This paper presents a conductive hydrogel coating for radiofrequency ablation catheters that enhances tissue contact and lesion homogeneity while preventing steam pops, though further optimization of conductivity is required to match the lesion dimensions of bare metal catheters.
By employing a machine-learning-guided strategy to engineer a disulfide bond that restricts the mobility of a conserved lid loop in *Anabaena variabilis* phenylalanine ammonia-lyase, researchers demonstrated that this loop acts as a critical regulator of substrate specificity by modulating active-site conformational dynamics.
This paper introduces "directoids," a microfluidic platform utilizing micropatterned PDMS channels to achieve spatially controlled, directional axonal guidance and asymmetric functional connectivity between cortical and thalamic neural organoids, thereby enabling the study of hierarchical circuit formation with unprecedented cellular resolution.
This study demonstrates that in APP/PS1 mouse models of Alzheimer's disease, circadian disruption exacerbates sex-specific bone loss and fragility by inducing oxidative stress and dysregulating circadian timing in bone marrow monocytes and macrophages.
This study demonstrates that muscle coordination patterns for efficient locomotion must change across different body sizes due to the non-linear effects of muscle tissue inertia, which significantly alters metabolic costs and mechanical output as muscle mass scales.
The study demonstrates that the BiArticular Thigh EXosuit (BATEX), which mimics biological biarticular muscles and elastic tissues to enable both temporal energy storage and spatial energy transfer across joints, significantly reduces metabolic cost by up to 9% during walking by simultaneously assisting and augmenting human lower-limb function.
This study demonstrates that glycoengineered small extracellular vesicles derived from Caco-2 and HEK293T cells, functionalized with Gb3 trisaccharides via FSL conjugates, effectively serve as decoy receptors to neutralize Shiga toxin 1 subunit B without compromising cell viability, offering a promising therapeutic strategy against STEC infections.
The MMH dataset is a multimodal collection of whole-body kinematics, ground reaction forces, and lower-limb electromyography signals recorded during various lifting and lowering techniques, designed to support research in biomechanics, ergonomics, and musculoskeletal modeling.
This study demonstrates that Nanofitin-based affinity chromatography using the NF06 binder enables the scalable, selective enrichment of CD81-positive extracellular vesicles with high recovery, effective impurity clearance, and EV-compatible elution conditions.
This study establishes a direct link between the microstructural changes of neuronal loss and gliosis and the increased tissue stiffness in hippocampal sclerosis, demonstrating that nonlinear mechanical properties serve as promising diagnostic biomarkers for drug-resistant temporal lobe epilepsy.
