Effectiveness of Various Light-Cure Biomaterials as an Intraorifice Barrier: An In Vitro Study.

Objective Proper seal achieved via placement of an effective intraorifice barrier curtails the occurrence of post-bleaching consequences and reinforces the cervical tooth structure. Hence, our present study aims to evaluate the effectiveness of three different light-cure biomaterials as an intraorifice barrier. Methodology Forty-eight sound human premolars were obtained, and root canal treatment procedures were accomplished according to the standard protocol.

A Role of Agrin in Maintaining the Stability of Vascular Endothelial Growth Factor Receptor-2 during Tumor Angiogenesis.

Endothelial cell (EC) recruitment is central to the vascularization of tumors. Although several proteoglycans have been implicated in cancer and angiogenesis, their roles in EC recruitment and vascularization during tumorigenesis remain poorly understood. Here, we reveal that Agrin, which is secreted in liver cancer, promotes angiogenesis by recruiting ECs within tumors and metastatic lesions and facilitates adhesion of cancer cells to ECs.
