Cardiac output but not stroke volume is similar in a Wingate and $$ \dot{V}{\text{O}}_{{ 2 {\text{peak}}}} $$ test in young men [PDF]

open access: yes, 2018
Wingate test (WT) training programmes lasting 2-3weeks lead to improved peak oxygen consumption. If a single 30s WT was capable of significantly increasing stroke volume and cardiac output, the increase in peak oxygen consumption could possibly be ...

Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes

open access: yesAdvanced Materials Technologies, EarlyView.
This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...

Evaluation of noninvasive cardiac output methods during exercise [PDF]

open access: yes
Noninvasive techniques to estimate cardiac output (Qc) will be used during future space flight. This retrospective literature survey compared the Qc techniques of carbon dioxide rebreathing (CO2-R), CO2 single breath (CO2-S), Doppler (DOP), impedance (IM)

Cardiac output measurement in children: comparison of Aesculon® cardiac output monitor and thermodilution [PDF]

open access: yes, 2017
Background We compared cardiac output (CO) measurements by the non-invasive electrical velocimetry (Aesculon®) monitor with the pulmonary artery catheter (PAC) thermodilution method in children.

Deep Separable Spatiotemporal Learning for Fast Dynamic Cardiac MRI [PDF]

open access: yesarXiv
Dynamic magnetic resonance imaging (MRI) plays an indispensable role in cardiac diagnosis. To enable fast imaging, the k-space data can be undersampled but the image reconstruction poses a great challenge of high-dimensional processing. This challenge necessitates extensive training data in deep learning reconstruction methods. In this work, we propose

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

open access: yesAdvanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Patient-Specific Dynamic Digital-Physical Twin for Coronary Intervention Training: An Integrated Mixed Reality Approach [PDF]

open access: yesarXiv
Background and Objective: Precise preoperative planning and effective physician training for coronary interventions are increasingly important. Despite advances in medical imaging technologies, transforming static or limited dynamic imaging data into comprehensive dynamic cardiac models remains challenging.

Multifunctional Fibrous Mats: Stretchable, Conductive, and Hydrophilic Platforms for Wearable Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
A hydrophilic, stretchable, nonwoven electrospun fiber mat targeted to be applied in long‐term bioelectronic devices. By incorporating amphiphilic polyethylene glycol block copolymers in a polydimethylsiloxane matrix, the material develops stable hydrophilicity, enhanced breathability, as well as enhanced adhesion to cells.
