Relationships between resting conductances, excitability, and t-system ionic homeostasis in skeletal muscle.
Activation of skeletal muscle fibers requires rapid sarcolemmal action potential (AP) conduction to ensure uniform excitation along the fiber length, as well as successful tubular excitation to initiate excitation-contraction...
Ultrasound Imaging Velocimetry with interleaved images for improved pulsatile arterial flow measurements
Katharine H Fraser, Chritian Poelma, Bin Zhou, Eleni Bazigou, Meng-Xing Tang, Peter D Weinberg
Feb 01, 2017
Blood velocity measurements are important in physiological science and clinical diagnosis. Doppler ultrasound is the most commonly used method but can only measure one velocity component. Ultrasound imaging velocimetry (UIV) is...
Personalized Numerical Cardiovascular Model with Weight Growth for Evaluating Pediatric Left Ventricular Assist Devices
Phong Tran, Victor Tedesco, Simon Kiang, Shweta Karnik, David Nguyen, O. H. Frazier, Katharine H. Fraser, Yaxin Wang
Feb 29, 2024
Pediatric patients with heart failure have limited treatment options because of a shortage of donor hearts and compatible left ventricular assist devices (LVADs). To address this issue, our group is developing an implantable...

Influence of shear-thinning blood rheology on the laminar-turbulent transition over a backward facing step
Cardiovascular diseases are the leading cause of death globally and there is an unmet need for effective, safer blood-contacting devices, including valves, stents and artificial hearts. In these, recirculation regions promote...

L q -spectra of self-affine measures
Abstract: We study L q -spectra of planar self-affine measures generated by diagonal matrices. We introduce a new technique for constructing and understanding examples based on combinatorial estimates for the exponential growth...
Numerical Comparison of Shear and Elongational Stresses in Rotary Ventricular Assist Devices
Background Despite the evolution of Ventricular Assist Devices (VADs), VAD patients still suffer from complications, often due to damage to the blood by fluid dynamic stress. To date, most numerical models for blood damage are...
Normal fluid stresses are prevalent in rotary ventricular assist devices
Despite the evolution of Ventricular Assist Devices (VADs), VAD patients still suffer from complications due to the damage to blood by fluid dynamic stress. Since rotary VADs are assumed to exert mainly shear stress, studies of...
MRI-based strain measurements reflect morphological changes following myocardial infarction
Doyin Odunmbaku-Mansell, Eva Sammut, V. D. Bruno, Raimondo Ascione, Jonathan C.L. Rodrigues, H S Gill, Katharine Fraser, Andrew Cookson
Jan 31, 2023
In a porcine experimental model of myocardial infarction, a localised, layer-specific, circumferential left ventricular strain metric has been shown to indicate chronic changes in ventricular function post-infarction more...
