A Hypoxia‐Responsive Single‐Atom Sonozyme for Targeted Sonocatalytic Therapy in Alleviating Atherosclerotic Plaque

Advanced Science, EarlyView.
A tetranitrogen‐coordinated single‐atom manganese catalyst (SMC) is fabricated with outstanding sonosensitization efficiency and multi‐enzyme‐like catalytic properties. To enable better targeting of M1 macrophages, hyaluronic acid (HA) is applied to modify the surface of SMC, yielding SMC‐HA nanozymes.

Herniation pit of the femoral neck [PDF]

American Journal of Roentgenology, 1982
A round to oval radiolucency surrounded by a thin zone of sclerosis is often identified in the proximal superior quadrant of adult femoral necks. Although usually recognized as incidental and benign, these radiolucencies may be of clinical concern in patients with hip symptoms. The true nature and genesis of these radiolucencies have not been explained.

Mitochondrial Transplantation Augments the Reparative Capacity of Macrophages Following Myocardial Injury

Advanced Science, EarlyView.
Mitochondrial transplantation induces macrophage polarization toward an anti‐inflammatory M2 phenotype, enhances their reparative capacities, and facilitates mitochondrial transfer to cardiomyocytes, collectively promoting tissue repair and functional recovery post‐myocardial infarction.

A “Mesoporous Oxygen Chamber” Scaffold with Antibacterial and Early Immunomodulatory Effect for Promoting Bone Regeneration

Advanced Science, EarlyView.
In this study, an oxygen‐loaded and antimicrobial peptide (AP)‐functionalized scaffold (MBGAPO) is synthesized. With mesoporous structure of MBG applied as an “oxygen storage,” and AP‐provided antibacterial ability against E.coli and MRSA. MBGAPO exhibited osteogenic and multiplex‐immunomodulatory effects.

Treatment of basicervical femoral neck fractures with proximal femoral nail antirotation

Journal of International Medical Research, 2019
Objective A basicervical femoral neck fracture, which is located at the junction between the femoral neck and intertrochanteric region, is a rare type of fracture. The treatment effects for this type of fracture vary.

FGF9–FGFR2 Signaling via Osteocytes‐Preosteoblasts Crosstalks to Mediate Mechanotransduction‐Driven Intramembranous Osteogenesis in the Underdeveloped Maxilla

Advanced Science, EarlyView.
This study identifies osteocyte‐derived FGF9 as a mechanosensitive factor that impairs osteogenesis in the underdeveloped maxilla by inducing FGFR2 nuclear translocation in preosteoblasts. Mechanical stimulation reduces FGF9 secretion, relieving its inhibitory effect. These findings reveal a novel osteocyte–preosteoblast FGF9–FGFR2 axis in craniofacial
