introduction: one of the hypotheses regarding the calcification induction by mineral trioxide aggregate (mta) is the involvement of transforming growth factor-beta (tgf- β ) super family. calcium-enriched mixture (cem) cement is one of the endodontic biomaterials with clinical applications similar to mta. the aim of the present in vitro study was to compare the induction of bone morphogenic pro...

background: determination of the impact of angiogenesis on tumor development and progression is essential. this study aimed to determine the serum levels of vascular endothelial growth factor (vegf) and interleukin 6 (il-6) in breast carcinoma, and to correlate them with tumor size, lymph node involvement, and cancer stage. methods: under aseptic precautions 5 ml of venous blood was collected f...

background: during antigen capture and processing, mature dendritic cells (dc) express large amounts of peptide-mhc complexes and accessory molecules on their surface. dc are antigen-presenting cells that have an important role in tolerance and autoimmunity. the transforming growth factor-beta1 (tgf-β1) cytokine has a regulatory role on the immune and non-immune cells. the aim of this study is ...
