A novel pilot animal model for bone augmentation using osseous shell technique for preclinical in vivo studies

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1331-1340, December 2022., 2022
Abstract Objectives Bone grafting is commonly used to reconstruct skeletal defects in the craniofacial region. Several bone augmentation models have been developed to evaluate bone formation using novel bone substitute materials. The aim of this study was to evaluate a surgical animal model for establishing a three‐dimensional (3D) grafting environment

Accuracy of vertical bitewing and bisect periapical radiography techniques in anterior mandibular teeth interdental bone resorption

مجله دانشکده دندانپزشکی اصفهان, 2009
Introduction: Alveolar bone level is changed due to the balance between bone formation and resorption. Radiographic examination has an important role in the diagnosis and treatment of periodontal diseases. This study was performed to compare the accuracy

Ultrasound imaging of cortical bone: cortex geometry and measurement of porosity based on wave speed for bone remodeling estimation [PDF]

arXiv
Intracortical US imaging extends B-mode imaging into bone using a dedicated image reconstruction algorithm that corrects for refraction at the bone-soft tissue interfaces. It has shown promising results in a few healthy, predominantly young adults, providing anatomical images of the cortex (periosteal and endosteal surfaces) along with estimations of ...

Biomimetic Microstructured Scaffold with Release of Re‐Modified Teriparatide for Osteoporotic Tendon‐to‐Bone Regeneration via Balancing Bone Homeostasis

Advanced Science, EarlyView.
This study develops RPTH by re‐modifying teriparatide and designs a biomimetic microstructured scaffold (BMRP) loaded with RPTH to address osteoporotic tendon‐to‐bone interface repair. The BMRP restores tissue architecture by balancing bone homeostasis and remodeling the microstructure, achieving functional recovery in an osteoporotic rotator cuff tear

Predictive Modelling of Bone Age through Classification and Regression of Bone Shapes [PDF]

arXiv, 2014
Bone age assessment is a task performed daily in hospitals worldwide. This involves a clinician estimating the age of a patient from a radiograph of the non-dominant hand. Our approach to automated bone age assessment is to modularise the algorithm into the following three stages: segment and verify hand outline; segment and verify bones; use the ...

Engineering Extracellular Vesicles Derived from 3D Cultivation of BMSCs Enriched with HGF Ameliorate Sepsis‐Induced Lung Epithelial Barrier Damage

Advanced Science, EarlyView.
3D culture of MSCs upregulates gene expression of matrix metalloproteinases (MMPs), growth factors (GFs), and increases the production of extracellular vesicles (EVs). Proteomic analysis reveals 642 upregulated proteins in 3D‐EVs, including HGF. These 3D‐EVs, enriched with HGF, protect lung epithelial cells from apoptosis and barrier damage in septic ...

Puerarin specifically disrupts osteoclast activation via blocking integrin-β3 Pyk2/Src/Cbl signaling pathway

Journal of Orthopaedic Translation, 2022
Objective: Given the limitations of current anti-resorption agents for postmenopausal osteoporosis, there is a need for alternatives without impairing coupling crosstalk between bone resorption and bone formation ie. osteoclastogenesis.
