Ultrasound provides a promising non-invasive, safe, objective means of monitoring and quantifying bone healing. In this paper, the relationship between the ultrasound image intensity and the acoustic impedance was exploited to develop a quantitative measure towards assessment and monitoring of the bone healing process. Information theoretic criterion (KLD) was used to quantify the degree of bone healing using the intensity histogram of the callus region obtained from B-Mode ultrasound. Results from a pilot experimental study, show that the proposed method is capable of accurately quantifying the degree of bone healing.

Exosomes, small extracellular vesicles secreted by various cells, play crucial roles in the pathogenesis and treatment of oral diseases. Recent studies have highlighted their involvement in orthodontics, periodontitis, oral squamous cell carcinoma (OSCC), and hand, foot, and mouth disease (HFMD). Exosomes have a positive effect on the inflammatory environment of the oral cavity, remodeling and regeneration of oral tissues, and offer promising therapeutic options for bone and periodontal tissue restoration.

Background: Regenerating periodontal ligament (PDL) tissue is a vital challenge in dentistry that aims to restore periodontal function and aesthetics. This study explores a tissue engineering strategy that combines polycaprolactone (PCL)/collagen/cellulose acetate electrospun scaffolds with collagen hydrogels to deliver curcumin-loaded ZIF-8 nanoparticles fand periodontal ligament stem cells (PDLSCs).
Methods: Scaffolds were fabricated via electrospinningand collagen hydrogels incorporated PDLSCs and curcumin-loaded ZIF-8 nanoparticles (CURZIF-8) were developed using cross-linking.

Tissue regeneration involves dynamic dialogue between and among different cells and their surrounding matrices. Bone regeneration is specifically governed by reciprocity between osteoblasts and osteoclasts within the bone microenvironment. Osteoclast-directed resorption and osteoblast-directed formation of bone are essential to bone remodeling, and the crosstalk between these cells is vital to curating a sequence of events that culminate in the creation of bone tissue.

Background: Uterine injury can cause uterine scarring, leading to a series of complications that threaten women's health. Uterine healing is a complex process, and there are currently no effective treatments. Although our previous studies have shown that bone marrow mesenchymal stem cells (BMSCs) promote uterine damage repair, the underlying mechanisms remain unclear.

Research on bone substitutes for repairing bone defects has drawn increasing attention, and the efficacy of three-dimensional (3D) printed bioactive porous scaffolds for bone defect repair has been well documented. Our previous studies have shown that psoralen can promote osteogenesis by activating the Wnt/β-catenin and BMP/Smad signaling pathways and their crosstalk effects, and psoralen nanospheres have a good osteogenesis-promoting effect with low cytotoxicity. The Chinese medicine oyster shell powder, characterized by its porous structure, strong adsorption, and unique bioactivity, has potential in fracture-promoting repair materials.
