Architected Soft Actuators for Artificial Musculoskeletal Systems

open access: yesAdvanced Materials, EarlyView.
An architected soft actuator uses a servo motor and a combination of 3D printed architected elastomers to extend and contract. The actuator exhibits high actuation stroke, force output, and power density for constructing bioinspired artificial musculoskeletal systems.

Smoothness of the knee joint movement during the stance phase in patients with severe knee osteoarthritis

open access: yesAsia-Pacific Journal of Sports Medicine, Arthroscopy, Rehabilitation and Technology, 2018
Background: Patients with knee osteoarthritis can significantly affect the function of the knee joint in terms of joint range and mobility and have a stereotypical pattern of knee stiffness during gait, caused by an increased resistance in the muscles ...

Patient Outcomes Following Hip and Knee Joint Replacement Surgery: Role of the Social and Physical Environment in Recovery [PDF]

open access: yes, 2016
Osteoarthritis is a degenerative joint disease that affects over 27 million Americans (Centers for Disease Control & Prevention, 2014). Joint replacement surgery is often recommended for patients who do not respond to conventional medical treatment. Post-

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Wireless Acousto‐Piezoelectric Conduit with Aligned Nanofibers for Neural Regeneration

open access: yesAdvanced Materials, EarlyView.
An ultrasound‐driven, highly aligned piezoelectric nanofiber‐based nerve guidance conduit (APNF‐NGC) designed for effective peripheral nerve repair has been demonstrated in this study. Featuring aligned topology, cell‐adhesive surfaces, and an axial electric field, the APNF‐NGC collectively promotes significant nerve regeneration.

Experimental joint immobilization in guinea pigs. Effects on the knee joint [PDF]

open access: yes
In young and adult guinea pigs, the aftermath experimentally induced by the immobilization of the knee joint in hyperextended forced position was studied. Joint immobilization which varied from one to nine weeks was attained by plaster.
