Management of Crown-root Fracture with 180-degree Rotation Replantation: a Report of 2 Cases.

Intentional replantation involves a combination of periodontics, endodontics, prosthodontics and oral surgery. Crown-root fracture management is still complicated nowadays. A fracture line extending longitudinally to the subgingival area and intruding bioogical width could affect infection control, gingival health and crown restoration.

Positive Correlation between Activated CypA/CD147 Signaling and MMP-9 Expression in Mice Inflammatory Periapical Lesion.

Aim: Cyclophilin A (CypA)/CD147 signaling plays critical roles in the regulation of inflammation and bone metabolism. This study aimed to investigate the participation of CypA/CD147 in mice periapical lesions progression and its relationship with bone resorption.

Methodology: Periapical lesions were induced by pulp exposure in the first lower molars of 40 C57BL/6J mice.

Clinical and laboratory features distinguishing between and envenomation.

Background: There are 6 species of venomous snakes in Taiwan. Two of them, () and (), can cause significant coagulopathy. However, a significant proportion of patients with snakebites cannot identify the correct snake species after envenomation, which hampers the application of antivenom.

Early predictors of responses and clinical outcomes of corticosteroid treatment for severe ulcerative colitis.

Background: Patients with severe ulcerative colitis (SUC) have a high risk of requiring colectomy or resorting to a second-line treatment. However, neither clinical outcomes nor factors predictive of poor response have been clearly established in the treatment of SUC.

Objective: To assess prospectively the effects and predictors of corticosteroids (CS) use in clinical outcomes of SUC during 1 year of follow-up.
