Matching TGF‐β1 Activation With Stress‐Responsive Charge‐Reversal Hydrogel Microspheres for the Treatment of Osteoarthritis

Exploration, EarlyView.
Based on the interaction between the weakly cross‐linked disulfide bonds that break under stress and charge‐reversal messenger molecules, we herein achieved nanoparticle charge reversal under stress and constructed a stress‐responsive charge‐reversal hydrogel microsphere system using microfluidic technology.

Smart Nanodelivery Systems for Immunometabolic Modulation in Osteoarthritis

Exploration, EarlyView.
Smart nanodelivery systems deliver therapeutic payloads across the cartilage matrix to ensure their sustained accumulation within chondrocytes at sites of injury. By targeting specific molecular targets and signaling pathways, these platforms modulate the pathological synovium‐cartilage axis to restore immunometabolic homeostasis and drive tissue ...

Gait alterations increase friction of degenerated articular cartilage: A tribological study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the effect of gait alterations associated with osteoarthritis (OA) on the frictional properties of porcine articular cartilage (AC) in intact and degenerative conditions. Methods Forty‐eight cylindrical AC samples were harvested from 12 porcine femur condyles and equally divided between four groups with n = 12 samples ...

Interaction of restoration processes with properties within copper‐graphene composites during direct consolidation Interaktion von Wiederherstellungsprozessen mit Eigenschaften innerhalb von Kupfer‐Graphen‐Verbundwerkstoffen während der direkten Konsolidierung

Materialwissenschaft und Werkstofftechnik, EarlyView.
By refining grains and additions of strengthening elements, mechanical properties of electro‐conductive copper can be increased. Fine‐grained coper‐graphene composites were directly consolidated from original powders by rotary swaging to achieve rods with enhanced mechanical properties and electric conductivity of up to 96% international annealed ...

Melt and Cold Crystallization Behavior of Poly(Lactic Acid) With Different Molecular Weights and Its Influence on Mechanical, Viscoelastic, and Tribological Properties

Polymer Engineering &Science, EarlyView.
Modifying the crystallinity of PLA and its properties through annealing. ABSTRACT The melt and cold crystallization behavior of two PLA grades with different molecular weights was investigated using various DSC analyses. During isothermal melt crystallization, PLA with lower molecular weight exhibited faster crystallization kinetics across different ...
