Clinical Outcomes of Intracardiac Echocardiography-Guided Radiofrequency Catheter Ablation for Atrial Fibrillation: A Retrospective Study. [PDF]
EchocardiographyICE‐guided radiofrequency catheter ablation is safe and effective in the treatment of atrial fibrillation, and it has potential advantages in terms of ablation time, radiation exposure, complication occurrence, and patient prognosis. ABSTRACT Background Routine radiofrequency catheter ablation relies on x‐ray imaging, which may increase the risk of ...

Clinical impact of very high-power-short-duration catheters on biomarkers after atrial fibrillation ablation. [PDF]
J ArrhythmDifferences in fluid irrigation (A), pre‐ and post‐procedure BNP absolute values change (B), and BNP percentage values change (C) in standard catheters (STD RF) versus very high‐power short‐duration catheters (vHPSD). vHPSD catheters use is associated with significantly less irrigation fluid than with standard STD RF catheters during pulmonary vein ...

D-band strain underestimates fibril strain for twisted collagen fibrils at low strains [PDF]
, 2021 Collagen fibrils are the main structural component of load-bearing tissues such as tendons, ligaments, skin, the cornea of the eye, and the heart. The D-band of collagen fibrils is an axial periodic density modulation that can be easily characterized by tissue-level X-ray scattering. During mechanical testing, D-band strain is often used as a proxy for

Non-equilibrium Growth and Twist of Cross-Linked Collagen Fibrils [PDF]
, 2020 The lysyl oxidase (LOX) enzyme that catalyses cross-link formation during the assembly of collagen fibrils in vivo is too large to diffuse within assembled fibrils, and so is incompatible with a fully equilibrium mechanism for fibril formation. We propose that enzymatic cross-links are formed at the fibril surface during the growth of collagen fibrils;

Uniform spatial distribution of collagen fibril radii within tendon implies local activation of pC-collagen at individual fibrils [PDF]
Physical Biology, v. 13 (2016) 046008, 2016 Collagen fibril cross-sectional radii show no systematic variation between the interior and the periphery of fibril bundles, indicating an effectively constant rate of collagen incorporation into fibrils throughout the bundle. Such spatially homogeneous incorporation constrains the extracellular diffusion of collagen precursors from sources at the ...

Graphene-based Distributed 3D Sensing Electrodes for Mapping Spatiotemporal Auricular Physiological Signals [PDF]
arXiv, 2021 Underneath the ear skin there are richly branching vascular and neural networks that ultimately connecting to our heart and brain. Hence, the three-dimensional (3D) mapping of auricular electrophysiological signals could provide a new perspective for biomedical studies such as diagnosis of cardiovascular diseases and neurological disorders. However, it

Amyloid Fibril Solubility [PDF]
J. Phys. Chem. B, 2015, 119 (46), pp 14631-14636, 2015 It is well established that amyloid fibril solubility is protein specific, but how solubility depends on the interactions between the fibril building blocks is not clear. Here we use a simple protein model and perform Monte Carlo simulations to directly measure the solubility of amyloid fibrils as a function of the interaction between the fibril ...

Advanced-Glycation Endproducts: How cross-linking properties affect the collagen fibril behavior [PDF]
arXiv, 2023 Advanced-Glycation-Endproducts (AGEs) are known to be a major cause of impaired tissue material properties. In collagen fibrils, the main building component of human tissue, these AGEs appear as fibrillar cross-links. When AGEs accumulate in collagen fibrils, a process often caused by diabetes and aging, the mechanical properties of the collagen fibril
