Evaluation of dental implant stability in bone phantoms: comparison between a quantitative ultrasound technique and resonance frequency analysis [PDF]

arXiv, 2019
Background Resonance frequency analyses and quantitative ultrasound methods have been suggested to assess dental implant primary stability. PurposeThe purpose of this study was to compare the results obtained using these two techniques applied to the same dental implants inserted in various bone phantoms.

Accurate Transcription Factor Activity Inference to Decipher Cell Identity from Single‐Cell Transcriptomic Data with MetaTF

Advanced Science, EarlyView.
MetaTF is a new computational framework that uses single‐cell RNA sequencing (scRNA‐seq) data to infer transcription factor activity with the aim to help in deciphering cells identity starting from a heterogeneous population, and apply it to characterize mouse hematopoietic stem cells and breast cancer epithelial cells, thus identifying a novel subset ...

Piezoelectric Biomaterials for Bone Regeneration: Roadmap from Dipole to Osteogenesis

Advanced Science, EarlyView.
Piezoelectric biomaterials convert mechanical forces into electrical signals, offering novel strategies to restore and modulate bone microenvironments for tissue engineering. This review examines molecular dipole origins, spatial arrangements, and pseudo‐piezoelectric mechanisms and highlights dipole‐engineering techniques for osteogenesis regulation ...

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.

M2 Macrophage‐Derived Extracellular Vesicles Reprogram Immature Neutrophils into Anxa1hi Neutrophils to Enhance Inflamed Bone Regeneration

Advanced Science, EarlyView.
This study reveals that M2‐EVs mitigate periodontitis‐induced bone resorption by modulating neutrophil fate. Single‐cell RNA sequencing identified an Anxa1hi neutrophil subpopulation with pro‐reparative properties. M2‐EVs disrupt neutrophil maturation, promoting this subpopulation through key reprogramming genes (Acvrl1, Fpr2). These findings highlight

Engineered Tissue Models to Decode Host–Microbiota Interactions

Advanced Science, EarlyView.
Host–Microbiota interactions in the human body. Created in BioRender. Ghezzi, C. (2025) https://BioRender.com/ihivskg. Abstract A mutualistic co‐evolution exists between the host and its associated microbiota in the human body. Bacteria establish ecological niches in various tissues of the body, locally influencing their physiology and functions, but ...
