Sex-dependent aortic valve pathology in patients with rheumatic heart disease.

open access: yesPLoS ONE, 2017
BackgroundRheumatic heart disease is an autoimmune disease caused by group A streptococci infection and frequently affects the aortic valve. Sex differences are common in the disease progression, treatment, and outcome. However, little is known about the

Programmable Continuous Electrowetting of Liquid Metal for Reconfigurable Electronics

open access: yesAdvanced Materials, EarlyView.
This work introduces a programmable continuous electrowetting (CEW) approach for the dynamic manipulation of liquid metal (LM), enabling directional control via electrochemical modulation. By leveraging laser‐induced graphene (LIG) substrates, a wide range of utilities is demonstrated, including fluidic “valves,” logic gates, and reconfigurable ...

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.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced 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.

A chronological history of heart valve prostheses to offer perspectives of their limitations

open access: yesFrontiers in Bioengineering and Biotechnology
Prosthetic heart valves (PHV) have been studied for around 70 years. They are the best alternative to save the life of patients with cardiac valve diseases. However, current PHVs may still cause significant disadvantages to patients.

Engineering Aging: Approaches to Model and Deconstruct Biological Complexity

open access: yesAdvanced Materials, EarlyView.
The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.
