Long noncoding RNA CDKN2B-AS1 silencing protects against esophageal cancer cell invasion and migration by inactivating the TFAP2A/FSCN1 axis.

Esophageal cancer (EC) is the most aggressive malignancy in the gastrointestinal tract. Long noncoding RNA cyclin-dependent kinase inhibitor 2 B antisense RNA 1 (CDKN2B-AS1) is implicated in EC development. However, the specific mechanisms involved remain poorly defined.

[Finite element analysis of the angulation designment of implant planning in the anterior maxilla].

Purpose: To provide theoretical reference for maxillary anterior restoration designment in clinics by observing the masticatory stress distribution of the implant-bone interface and the displacement of implant.

Methods: This study built simplified 3 dimensional finite models with different angles, which included partial implant (4.3 mm×11.
