3D bioprinting of collagen to rebuild components of the human heart

open access: yesScience, 2019
If I only had a heart 3D bioprinting is still a fairly new technique that has been limited in terms of resolution and by the materials that can be printed. Lee et al.

Skin‐Interfaced Therapeutic Patches for Wound Fluid Management and Transdermal Drug Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an integrated skin‐interfaced device combining microfluidics, hydrogel film technology, flexible electronics, and iontophoresis‐based transdermal delivery of PDRN to enhance wound healing. The device effectively manages wound fluid, maintains optimal moisture, and non‐invasively delivers therapeutic drugs.

Bridging aortic valve surgery to 21st century. what can a surgeon do [PDF]

open access: yes, 2019
Aortic valve stenosis is the most clinically relevant valvular heart disease in the elderlies. Surgical aortic valve replacement (SAVR) represented, for decades, the standard of care for the treatment of severe aortic stenosis.

Telocytes in human heart valves

open access: yesJournal 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 ...

Flexible Polypyrrole‐Based pH Sensors via Oxidative Chemical Vapor Deposition

open access: yesAdvanced Healthcare Materials, EarlyView.
Oxidative chemical vapor deposition (oCVD) of polypyrrole (PPy) thin films yields flexible, electrically conductive, and biocompatible pH sensors for monitoring on‐skin biological events. The highly sensitive, oCVD PPy skin‐conformal sensors enable real‐time, spatially resolved sensing of dynamic pH changes within physiologically relevant ranges (4–9 ...

Magnetic resonance imaging is a safe technique in patients with prosthetic heart valves and coronary stents

open access: yesHellenic Journal of Cardiology, 2019
The paper refers to the safety of MRI in patients with prosthetic heart valves or coronary stents. This condition is commonly regarded as a contraindication for MRI, where patients with these stents or valves are excluded from yielding the diagnostic ...

Sir Dominic Corrigan: Healer of Hearts [PDF]

open access: yes, 1961
We present another vignette in our series of Catholic Men of Medicine. Sir Dominic Corrigan made definite contribution in his studies of the actions of the heart and his story should be of interest to our ...

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia

open access: yesAdvanced Healthcare Materials, EarlyView.
This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can

Prosthetic Heart Valve Thrombosis

open access: yesJournal of the American College of Cardiology, 2016
Although surgery was the mainstay of treatment for valvular heart disease, transcatheter valve therapies have grown exponentially over the past decade. Two types of artificial heart valve exist: mechanical heart valves (MHV), which are implanted surgically, and bioprosthetic heart valves (BHV), which can be implanted via a surgical or transcatheter ...
