Telocytes in human heart valves
Journal of Cellular and Molecular Medicine, 2014 Valve interstitial cells (VICs) are responsible for maintaining the structural integrity and dynamic behaviour of the valve. Telocytes (TCs), a peculiar type of interstitial cells, have been recently identified by Popescu's group in epicardium ...

Mechanistic Insights into the Surface Instabilities of TiNb2O7, a High‐Power Li‐Ion Anode
Advanced Materials Interfaces, EarlyView.TiNb2O7 is an attractive anode for Li‐ion batteries, particularly when safety is of the highest concern. However, despite operating at high potentials, electrolyte degradation is a major concern. It is demonstrated that throughout the entire charge‐discharge cycle a number of surface reactions occur which both produce gas and result in Ti dissolution ...

Soft Electromagnetic Actuator and Oscillator
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This work presents a groundbreaking soft electromagnetic system capable of bistable actuation and self‐regulated oscillation. Using liquid metal and silicone as a compliant conductor, the actuator enables force generation, sensing, and feedback with minimal power.

Dynamics of Cryoprotectant Permeation in Porcine Heart Valve Leaflets
Cell Transplantation, 2003 Valve replacement is a common cardiovascular procedure for the treatment of a variety of congenital and acquired defects. Many surgical programs rely on cryopreserved heart valves from regional tissue bank programs to meet clinical demands.

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Stochastic Modelling and Dynamic Analysis of Cardiovascular System with Rotary Left Ventricular Assist Devices [PDF]
Mathematical Problems in Engineering, 2018, 2018 The left ventricular assist device (LVAD) has been used for end-stage heart failure patients as a therapeutic option. The aortic valve plays a critical role in heart failure and its treatment with LVAD. The cardiovascular-LVAD model is often used to investigate the physiological demands required by patients and predict the hemodynamic of the native ...

Estimation of Cardiac Valve Annuli Motion with Deep Learning [PDF]
arXiv, 2020 Valve annuli motion and morphology, measured from non-invasive imaging, can be used to gain a better understanding of healthy and pathological heart function. Measurements such as long-axis strain as well as peak strain rates provide markers of systolic function.

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]
arXiv, 2018 An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological pulsatile flow.
