Elbow and knee joint for hard space suits [PDF]

, 1986
An elbow or knee joint for a hard space suit or similar usage is formed of three serially connected rigid sections which have truncated spherical configurations. The ends of each section form solid geometric angles, and the sections are interconnected by

Structure, Mechanics, and Mechanobiology of Fibrocartilage Pericellular Matrix Mediated by Type V Collagen

Advanced Science, EarlyView.
This study defines the structure, mechanics, and mechanobiology of the fibrocartilage pericellular matrix (PCM) using the murine meniscus, showing how collagen V deficiency alters PCM properties and disrupts cell mechanosensitive signaling. Findings emphasize the critical role of PCM in fibrocartilage mechanobiology and suggest targeting it can enhance

Constructing Ion‐Bridging Structure with Controlled Cracks in Plasticized PVC with Graphene for Highly Sensitive Strain Sensor with a Wide Strain Range

Advanced Science, EarlyView.
A highly stretchable strain sensor is presented, that leverages controlled crack formation and ion bridging in a polyvinyl chloride gel/graphene to achieve exceptional sensitivity (gauge factor up to 1.5 × 10⁶) and mechanical stability. By optimizing plasticizer properties, the conductive pathways are finely tuned, enabling robust, real‐time monitoring

Chondrocalcinosis is common in the absence of knee involvement [PDF]

, 2012
Introduction: We aimed to describe the distribution of radiographic chondrocalcinosis (CC) and to examine whether metacarpophalangeal joint (MCPJ) calcification and CC at other joints occurs in the absence of knee involvement.

Eosinophils‐Induced Lumican Secretion by Synovial Fibroblasts Alleviates Cartilage Degradation via the TGF‐β Pathway Mediated by Anxa1 Binding

Advanced Science, EarlyView.
Eosinophils play a crucial role in the progression of temporomandibular joint osteoarthritis (TMJOA). This study demonstrates that eosinophils, induced by OVA/IL‐5, promote Lumican secretion in the synovium, which binds to Annexin A1 in chondrocytes, inhibiting transforming growth factor β2 and Smad2/3 phosphorylation.
