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

Advanced 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.

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

Advanced 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

Advanced 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 ...

Physical Intelligence in Small‐Scale Robots and Machines

Advanced 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.

Effect of cyclic deformation on xenogeneic heart valve biomaterials.

PLoS ONE, 2019
Glutaraldehyde-fixed bovine pericardium is currently the most popular biomaterial utilized in the creation of bioprosthetic heart valves. However, recent studies indicate that glutaraldehyde fixation results in calcification and structural valve ...

The role of fibroblast growth factor 1 and 2 on the pathological behavior of valve interstitial cells in a three-dimensional mechanically-conditioned model

Journal of Biological Engineering, 2019
Background More than five million Americans suffer from heart valve disease annually, a condition that worsens cardiac function and gradually leads to heart failure if appropriate treatment is not performed on time. Currently no medication can cure heart

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Successful Treatment of Acute Lymphoblastic Leukemia in a Child with Trisomy 21 and Complex Congenital Heart Disease with Mechanical Prosthetic Valve

Case Reports in Pediatrics, 2012
A 10-year-old girl with trisomy 21 and complex congenital heart disease presented with acute lymphoblastic leukemia. Her chemotherapy required modifications due to poor baseline cardiac status and a mechanical prosthetic heart valve that was dependent on

Transvalvular mitral regurgitation following mitral valve replacement a diagnostic dilemma

Annals of Cardiac Anaesthesia, 2015
After mitral valve replacement with a prosthetic valve, the valve should be competent and there should not be any residual prosthetic valve regurgitation. Transvalvular residual prosthetic valve regurgitation are difficult to diagnose and quantify.

Heartbeat: Warfarin therapy for mechanical heart valves [PDF]

Heart, 2017
Although many patients requiring long term anti-thrombotic therapy now can be treated with direct oral anticoagulants (DOACs), vitamin K antagonists, such as warfarin, remain the only treatment option in patients with mechanical heart valves (MHVs). In the future, we can expect that fewer patients will receive (MHVs), given that surgical repair often ...
