High Quality Molecular Beam Epitaxy Growth And Characterization Of Lead Titanate Zirconate Based Complex-Oxides, Xing Gu
Theses and Dissertations
Research interest in complex oxides has resurged owing to progress in modern epitaxial techniques. Among such oxides, lead-titanate-based thin films such as PbTiO3 (PTO) and Pb(ZrxTi1−x)O3 (PZT) offer attractive advantages for a wide variety of applications. Moreover, integration between functional oxides with compound semiconductors has the potential to realize multi-functional devices which enjoy the properties from both groups of materials. Ferroelectric materials with a perovskite structure (ABO3) and semiconductors such as GaN with a hexagonal structure, require a careful choice of a bridge layer and suitable epitaxial technique. Molecular beam epitaxy (MBE) …
The Role Of Secreted Phosphoprotein-24 In Osteoblast Differentiation And Matrix Mineralization, Samuel Ramage
The Role Of Secreted Phosphoprotein-24 In Osteoblast Differentiation And Matrix Mineralization, Samuel Ramage
Theses and Dissertations
Secreted Phosphoprotein-24 (Spp24) was initially isolated and characterized as a component of bovine cortical bone matrix. Subsequent characterization has shown it is multiply phosphorylated and homologous to cystatin and TGF-β receptor type II. Spp24 is a minor component of the serum fetuin mineral complex that binds calcium-phosphate minerals and prevents their deposition. The TGF-β receptor homology domain binds BMP-2 weakly in vitro and enhances BMP-2’s osteogenic effects in vivo. The ability of Spp24 to affect BMP activity suggests an important role for Spp24 as a native, bioactive componentof bone that regulates bone development.
Spp24 was highly up-regulated in rat cortical …
