Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Femoral osteotomy for osteonecrosis of the femoral head

Journal of Joint Surgery and Research, 2023
Purpose: Osteotomy is a joint-preserving procedure for the treatment of osteonecrosis of the femoral head. This article aimed to present current knowledge on the two types of femoral osteotomy, namely transtrochanteric rotational osteotomy of the femoral head and curved varus osteotomy of the proximal femur. Methods: This clinical review summarizes the

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

CT-Based Evaluation of Bone Mineral Density Distribution of Proximal Femur in Patients With Femoral Trochanteric Fracture

Geriatric Orthopaedic Surgery & Rehabilitation
Background Surgical treatment of proximal femoral fractures typically involves fixation with intramedullary nailing or sliding hip screws, where screws inserted into the femoral head stabilize the fracture site.

Femoral Head Reduction Osteotomy for the Treatment of Severe Femoral Head Deformities and Articular Incongruity in Children with Perthes Disease [PDF]

Travmatologiâ i Ortopediâ Rossii
Background. Lack of adequate treatment for children with Perthes disease leads to the formation of severe femoral head deformity with articular surfaces incongruity, followed by the development of femoroacetabular impingement and early hip osteoarthritis.

PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

Advanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

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.

Proper mechanical stress promotes femoral head recovery from steroid-induced osteonecrosis in rats through the OPG/RANK/RANKL system

BMC Musculoskeletal Disorders, 2020
Background Long-term use of steroid may lead to osteonecrosis of the femoral head (ONFH). Mechanical stress may help bone formation and remodeling. This study aimed to probe the role of mechanical stress in the femoral head recovery in rats.

Testosterone Delays Bone Microstructural Destruction via Osteoblast‐Androgen Receptor‐Mediated Upregulation of Tenascin‐C

Advanced Science, EarlyView.
This study reveals that Testosterone–Androgen Receptor signaling delays elderly male bone destruction by upregulation of the osteoblastic extracellular tenascin‐C (TNC). The osteoprotective effect of fibrinogen C‐terminus of TNC is demonstrated in male osteoporotic mice model that osteoblast‐specific Ar‐knockout, potentially via inhibition of ...

Pinosylvin Inhibits Inflammatory and Osteoclastogenesis via NLRP3 Inflammasome

Advanced Science, EarlyView.
Pinosylvin blocks LPS and RANKL induced NEK7/NLRP3 interaction, inhibiting NLRP3 inflammasome oligomerization and assembly, reducing IL‐1β maturation and GSDMD cleavage, and improving the inflammatory microenvironment and abnormal osteoclastogenesis. Abstract Pro‐inflammatory cytokines such as TNF, IL‐1, and IL‐6 trigger aberrant osteoclastogenesis and
