Shear bond strength of different bonding agents to orthodontic metal bracket and zirconia.

This study aimed to evaluate the shear bond strength (SBS) of four bonding agents used to bond metal brackets to zirconia under different storage conditions. Four bonding agents were used [FLC: (Fuji ORTHO LC), XT: (Transbond XT), RUC-SBU: (Rely X Ultimate Clicker Adhesive Resin Cement+Single Bond Universal), and RUC-GBU: (Rely X Ultimate Clicker Adhesive Resin Cement+Gluma Bond Universal)] to bond two types of metal brackets (PT/3M) to zirconia surfaces, and they were stored in water at 37ºC for 24 h or thermocycling for 3,000 cycles. The SBS data of RUC-SBU and RUC-GBU using PT brackets were significantly higher than those of 3M brackets before and after thermocycling.

Biodegradability and Cytocompatibility of 3D-Printed Mg-Ti Interpenetrating Phase Composites.

Orthopedic hybrid implants combining both titanium (Ti) and magnesium (Mg) have gained wide attraction nowadays. However, it still remains a huge challenge in the fabrication of Mg-Ti composites because of the different temperatures of Ti melting point and pure Mg volatilization point. In this study, we successfully fabricated a new Mg-Ti composite with bi-continuous interpenetrating phase architecture by infiltrating Mg melt into Ti scaffolds, which were prepared by 3D printing and subsequent acid treatment.

Roles of the HGF/Met signaling in head and neck squamous cell carcinoma: Focus on tumor immunity (Review).

c‑mesenchymal‑epithelial transition (Met) is a transmembrane tyrosine kinase receptor of hepatocyte growth factor (HGF). HGF/Met signaling stimulates numerous pathways, including the Ras/mitogenactivated protein kinase (MAPK), phosphatidylinositol 3‑kinase/protein kinase B and Wnt/β‑catenin pathways, which serve important roles in cell proliferation, survival, motility, invasion and angiogenesis, and promotes the development and progression of tumors. Aberrant HGF/Met signaling is associated with a poor prognosis in several types of tumors, including head and neck squamous cell carcinoma (HNSCC).
