Degradable, Skin‐Conformal Nanocomposite‐Based Bioelectronic Patches for High‐Fidelity Electrophysiology and Gesture‐Controlled Robotics

open access: yesAdvanced Functional Materials, EarlyView.
A degradable, skin‐conformal bioelectronic patch combines a starch‐dominated nanocomposite conductor with a gelatin substrate to enable sensitive strain sensing, high‐fidelity electrocardiography, electromyography, electrooculography, and machine‐learning‐assisted gesture control.

Comparison of right ventricular global longitudinal strain between pacemaker lead position in patients with permanent pacemaker

open access: yesMajalah Kardiologi Indonesia
Background: The implantation of a permanent pacemaker (PPM) can reduce right ventricular function. Echocardiography using speckle tracking can detect a decreasing in right ventricular function earlier.

Left ventricular torsion rate and the relation to right ventricular function in pediatric pulmonary arterial hypertension

open access: yesPulmonary Circulation, 2018
The right ventricle and left ventricle are physically coupled through the interventricular septum. Therefore, changes in the geometry and mechanics of one ventricle can directly affect the function of the other.

Poisson's Ratio‐Driven Control of Myogenic Differentiation and Maturation in Auxetic Metamaterials under Dynamic Mechanical Stimulation

open access: yesAdvanced Functional Materials, EarlyView.
This study explored how innovative “auxetic” scaffolds, which expand when stretched, influence skeletal muscle development. Researchers cultured muscle cells on different scaffold designs and applied repeated stretching over 10 days. They found that scaffold geometry affected muscle cell differentiation and fiber formation.

PDE2 activity differs in right and left rat ventricular myocardium and differentially regulates β2 adrenoceptor-mediated effects [PDF]

open access: yes, 2015
The important regulator of cardiac function, cAMP, is hydrolyzed by different cyclic nucleotide phosphodiesterases (PDEs), whose expression and activity are not uniform throughout the heart. Of these enzymes, PDE2 shapes β1 adrenoceptor-dependent cardiac

A Constraint‐Based Analytical Framework for Design‐Space Analysis and Material Screening of Tubular Multilayer Dielectric Elastomer Pumps for Extracorporeal Circulatory Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A constraint‐based analytical framework maps the coupled effects of material properties, structural parameters, and operating conditions in tubular dielectric elastomer pumps for extracorporeal circulatory applications. The approach defines performance boundaries through mechanical, electrical, and hydraulic constraints and identifies feasible design ...

The role of the right ventricle in pulmonary arterial hypertension [PDF]

open access: yesEuropean Respiratory Review, 2011
Although changes in the pulmonary vasculature are the primary cause of pulmonary arterial hypertension (PAH), severity of symptoms and survival are strongly associated with right ventricular function, and right heart failure is the main cause of death in

Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.
