Epstein-Barr virus Zta upregulates matrix metalloproteinases 3 and 9 that synergistically promote cell invasion in vitro. [PDF]

PLoS ONE, 2013
Zta is a lytic transactivator of Epstein-Barr virus (EBV) and has been shown to promote migration and invasion of epithelial cells. Although previous studies indicate that Zta induces expression of matrix metalloproteinase (MMP) 9 and MMP1, direct ...

Linear Shrinkage of the ZTA Ceramic Cutting Inserts

Procedia Chemistry, 2016
AbstractLinear shrinkage of three types of ZTA ceramic cutting tool investigated in this research. Three types of ZTA tools fabricated in this study which are ZTA-MgO (micro), ZTA-MgO (nano) and ZTA-MgO-CeO2. Each of them were fabricated by wet mixing the materials and dried at 100 ̊C before crushed into powder.
