ROS‐Targeted Nanomotor Therapy in OA: Cartilage Protection and Pain Relief

Advanced Science, EarlyView.
ROS‐responsive NM@MET nanomotors utilize elevated ROS in osteoarthritic joints to promote deep penetration into cartilage and synovium and enable sustained metformin release. By scavenging ROS, regulating NRF2/KEAP1 signaling, protecting chondrocytes, suppressing synovial inflammation, and attenuating nociceptive signaling, NM@MET alleviates pain and ...

A Novel Dynamic Compression Angle-Stable Interlocking Intramedullary Nail: Description, Validation, and Model Evaluation

Veterinary Medicine International
The stabilization of long-bone fractures using intramedullary nails offers significant biological advantages for bone healing. Nevertheless, the mechanical stability of the implant–bone interface remains suboptimal due to the absence of models capable of

Static Study and Finite Element Analysis of a New Method of Fixation of a Medial Humerus Fracture by an Intramedullary Nailing System Analyzed by the ANSYS Workbench 16.2 Calculus Code

Nano Biomedicine and Engineering, 2019
Comminuted fractures of the humerus are generally treated with the intramedullary rod fixed by screws or locking plate system, and clinical results are satisfactory. We also know very well that the success of this agriculture depends on the stability and

A Disulfide‐Sticker Strategy for Marine Adhesive Coatings: From Deciphering Self‐Assembly Mechanism to Functional Application in Hair Regeneration

Advanced Science, EarlyView.
A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,

Predictive value of tip apex distance and calcar-referenced tip apex distance for cut-out risk in intertrochanteric femur fractures treated with double lag screw proximal femoral nails

Acta Orthopaedica et Traumatologica Turcica
Objective: Cut-out is a major mechanical complication following proximal femoral nailing for intertrochanteric femur fractures. Tip apex distance (TAD) and calcar-referenced TAD (CalTAD) are key radiographic parameters used to predict this complication.

HMGCR‐Driven Cholesterol Metabolism Promotes Osteoarthritis Progression by Accelerating Synovial Fibroblast Senescence

Advanced Science, EarlyView.
In the pathological context of osteoarthritis (OA), the phosphorylation of AKT1 at Ser473 enhances its binding to Lys140 of Insig1, which facilitates the formation of AKT1–Insig1 complex. Subsequently, the activation of AKT1 promotes the phosphorylation of Insig1 at Ser189, potentially enhancing the dissociation of Insig1 from sterol regulatory element‑
