Role of Autophagy in Angiogenesis Induced by a High-Glucose Condition in RF/6A Cells.

Purpose: To study the effect of autophagy on vitality, migration, and tube formation of RF/6A cells under the condition of D-glucose.

Methods: Cultured RF/6A cells were randomly divided into 4 groups (control, low glucose, high glucose, and high glucose with 3-methyladenine [3-MA]). Autophagy-related proteins (Atg7, p62, and LC3) were monitored.

Psychological stress delays periodontitis healing in rats: the involvement of basic fibroblast growth factor.

Objective: To evaluate the effects of psychological stress on periodontitis healing in rats and the contribution of basic fibroblast growth factor (bFGF) expression to the healing process.

Methods: Ninety-six rats were randomly distributed into control group, periodontitis group, and periodontitis plus stress group. Then, the rats were sacrificed at baseline and week(s) 1, 2, and 4.
