Pulmonary Stenosis and Right Ventricular Pressure

open access: yesJapanese Heart Journal, 1969
A correlation between RVP and the ratio RA/SB in pulmonary stenosis has been demonstrated for cases investigated in different countries.This distinguishes between operative and non-operative cases.

3D Printing of Conducting Polymer Hydrogels for Electrostimulation‐Assisted Tissue Engineering

open access: yesAdvanced Materials, EarlyView.
This review highlights nanosized inherently conducting polymers (ICPs) as promising ink constituents for 3D printing of conducting hydrogel (CH)‐based electrostimulation (ES) devices. ICP‐based ink formulation, 3D printing, and solidification strategies are discussed, along with the application of 3D‐printed ICP‐based CHs as ES platforms for regulating

A Hydro‐Expansive and Degradable Biomaterial Enabling Shape Recovery of Film‐Based Devices in Biofluids

open access: yesAdvanced Materials, EarlyView.
A chitosan‐based bio‐composite exhibits stable and strong tensile strength during volumetric expansion in body fluids, serving as a functional coating that enables a thin film‐based device to self‐flatten from its tubular shape required for catheter delivery.

Design of a Simple and Rugged Soft Polydimethylsiloxane‐Carbon Nanotube‐Graphene‐Based Composite Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
This research presents an easy to fabricate, low‐cost, flexible piezoresistive deformation sensor comprised of a carbon nanotube, few‐layer graphene, and polydimethylsiloxane composite. The sensor detects deformations and vibrations up to 600 Hz with 0.1% strain sensitivity from stiff and soft targets in dry and wet environments.

The physiology of left ventricular pressure fall.

open access: yesRevista portuguesa de cardiologia : orgao oficial da Sociedade Portuguesa de Cardiologia = Portuguese journal of cardiology : an official journal of the Portuguese Society of Cardiology, 2000
Left ventricular pressure (LVP) fall is the hemodynamic manifestation of myocardial relaxation. This paper reviews the most important aspects of LVP fall and its regulation by load, inactivation and nonuniformity. This regulation is explained in terms of calcium transients and cross-bridge mechanics.
