The bone transport technique uses the principle of distraction-osteogenesis and fill bone defects with the aid of an external fixator. In order to evaluate the clinical effect of femoral internal fixation with Ortho-Bridge System after bone transport, 4 patients after femoral bone transport from October 2020 to October 2022 are studied in this paper. Among them, 3 patients ran refracture of femur after removal of the Limb reconstruction system, 1 patient just finish femoral bone transport and request internal fixation. The surgery results show that Ortho-Bridge System can be used in the situation that conventional Locking compression plate and intramedullary nail are not suitable due to anatomical variation after femoral bone transport. Key words: femoral fracture; Ortho-Bridge System; bone transport; postoperative complications of bone transport.

Aims: Human periodontal ligament stem cells (hPDLSCs) exhibit an enormous potential to regenerate periodontal tissue. However, their translatability to the clinical setting is constrained by technical difficulties in standardizing culture conditions. The aim was to assess complex culture conditions using a proteomic-based protocol to standardize multi-layer hPDLSC cultivation methodology.

Objectives: In this study, buprenorphine was the primary source of maternal opioid exposure at the time of initial prenatal evaluation. Current recommendations advise that level II ultrasounds be performed in patients with substance use disorders. For some patients, distance, transportation, and costs associated with obtaining ultrasounds from a specialist pose significant barriers.

Inhibition of human concentrative nucleoside transporter 2 (CNT2) could suppress increases in serum urate levels derived from dietary purines. However, the structural basis for substrate recognition of CNT2 is still unknown and only a few inhibitors have been reported. In this study, a homology model of CNT2 was constructed and residues T315, E316, N426, N491, E492, F536 and N538 were identified as binding sites for adenosine through site-directed mutagenesis and a H-adenosine uptake assay.

This review summarizes the mechanism and role of physical activity in maintaining the proper functioning of the musculoskeletal system. Bone adaptation to the mechanical environment occurs in skeletal regions subjected to the greatest stresses resulting from the nature of exercise, however, there is a varied response of bone tissue to mechanical loads depending on its material and structural properties (trabecular and cortical). The regulation of bone tissue metabolism during physical exercise is influenced by factors associated with mechanical stress (gravitational forces, impact loading, and muscular contractions) as well as by systemic mechanisms (hormones, myokines, cytokines).
