An Injectable and Self‐Reinforced Piezoelectric Hydrogel for Irregular Bone Defects Regeneration: Dynamic Epigenetic Regulation Approach

open access: yesAdvanced Science, EarlyView.
An injectable and self‐reinforcing RSF‐based piezoelectric hydrogel conforms to irregular bone defects and progressively strengthens in situ, overcoming the trade‐off between injectability and mechanical stability. Mechanical loading generates bioelectrical cues that promote P300‐mediated H3K9 acetylation and upregulate PTH1R expression, thereby ...

Costovertebral anomalies in osteogenesis imperfecta

open access: yes, 1985
Study of 16 patients with Type III osteogenesis imperfecta showed marked elongation of the pedicles of the vertebrae in all cases, a deformity which was not seen in other types of the disease. Posterior rib angulation was also noted in Type III disease.

Avulsion fracture of the olecranon for the diagnosis of osteogenesis imperfecta case report

open access: yesActa Orthopaedica et Traumatologica Turcica, 2021
Avulsion fractures of olecranon in children are very rare and often associated with osteogenesis imperfecta. In this study we report a child who has been followed for constitutional growth retardation for five years.

The Potential of Self‐Maintainable Living Materials

open access: yesAdvanced Science, EarlyView.
Self‐maintainable living materials are presented as the next generation of bioadaptive systems, integrating continuous sensing, decision‐making, response, self‐repair, and adaptation in a closed‐loop framework. This review highlights the design principles and emerging technologies that enable autonomous, long‐term functionality for future regenerative ...

Micro-/nano-structured zirconia surface promotes osteogenic differentiation of human bone marrow mesenchymal stem cells by reducing pyroptosis under inflammatory conditions

open access: yesJournal of Dental Sciences
Background/purpose: Promoting osteogenesis under inflammatory conditions holds promise for preventing and mitigating peri-implantitis. Cell pyroptosis inhibits osteoblast-mediated bone formation.

Yoda1‐Functionalized Nanozymes Coordinate Piezo1 Activation and Mitochondrial Protection to Reprogram the Diabetic Osteoimmune Micromilieu and Promote Vascularized Bone Repair

open access: yesAdvanced Science, EarlyView.
Diabetic bone defects remain a critical clinical challenge. A 3D‐printed BCPG‐MF@Y scaffold, embedding Yoda1‐functionalized manganese dioxide‐ferritin nanozymes, scavenges mtROS, suppresses the cGAS–STING pathway, and reverses cellular senescence, while Yoda1 activates Piezo1 to direct BMSCs fate to synergistically reprogram the osteoimmune ...

Engineering Spatially Localized Bioactive Microenvironments in Assembly Implants for Spatially Extended Bone Ingrowth

open access: yesAdvanced Science, EarlyView.
An assembly porous titanium/β‐TCP implant is developed to establish a spatially programmable osteogenic microenvironment for enhanced osseointegration. By decoupling mechanical support from bioactive ion release, localized ionic gradients generated from the β‐TCP module direct osteogenic activity and bone ingrowth toward the porous titanium framework ...

A Hypothalamic Oxytocinergic–Sympathetic Axis Couples Anxiety Dysregulation With Impaired Tendon–Bone Repair

open access: yesAdvanced Science, EarlyView.
RCI is associated with functional suppression of oxytocinergic neurons in the PVN. Reduced PVNOXT neuronal activity contributes to altered sympathetic regulation involving the IML–sympathetic chain pathway, accompanied by changes in norepinephrine signaling at the BTI.

[Prenatal diagnosis of osteogenesis imperfecta. Report of a case].

open access: yes, 1999
Osteogenesis imperfecta is a heterogeneous group of connective tissue disorders; it is characterized by blue scleras, bone fragility and deformity secondary to recurring fractures. A case of osteogenesis imperfecta personally observed at the 21st week of
