Predicting Disease Progression and Mortality in Aortic Stenosis: A Systematic Review of Imaging Biomarkers and Meta-Analysis

open access: yesFrontiers in Cardiovascular Medicine, 2018
Background: Detecting among patients with aortic stenosis (AS) those who are likely to rapidly progress, yet potentially benefiting from prophylactic aortic valve replacement, is needed for improved patient care.

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.

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 ...

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

open access: yesAdvanced Materials, EarlyView.
This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.

Multifunctional Fluidic Units for Emergent, Responsive Robotic Behaviors

open access: yesAdvanced Materials, EarlyView.
A multifunctional reconfigurable fluidic unit can be used as sensor, valve and actuator is presented. A unique configuration combines the features of the three components as a Responsive self‐oscillating actuator. The remarkable versatility of the fluidic unit is demonstrated by building different robots with the same fluidic units only by varying ...

Tissue-engineered heart valves

open access: yesPhysiological Research, 2009
Currently-used mechanical and biological heart valve prostheses have several disadvantages. Mechanical prostheses, based on carbon, metallic and polymeric components, require permanent anticoagulation treatment, and their usage often leads to adverse reactions, e.g. thromboembolic complications and endocarditis.

Physical Intelligence in Small‐Scale Robots and Machines

open access: yesAdvanced Materials, EarlyView.
“Physical intelligence” (PI) empowers biological organisms and artificial machines, especially at the small scales, to perceive, adapt, and even reshape their complex, dynamic, and unstructured operation environments. This review summarizes recent milestones and future directions of PI in small‐scale robots and machines.

Heart Valve Tissue Engineering [PDF]

open access: yesCirculation Research, 2005
Tissue-engineered heart valves have been proposed by physicians and scientists alike to be the ultimate solution for treating valvular heart disease. Rather than replacing a diseased or defective native valve with a mechanical or animal tissue–derived artificial valve, a tissue-engineered valve would be a living organ, able to respond to growth and ...
