Cisplatin targets the stromal cell-derived factor-1-CXC chemokine receptor type 4 axis to suppress metastasis and invasion of ovarian cancer-initiating cells
In ovarian cancer, CD44+/CD117+ stem cells, also known as cancer-initiating cells (CICs), are highly proliferative and invasive. Therefore, the CD44+/CD117+ subpopulation is thought to be an important target f...

Influence of carburization followed by shot peening on fatigue property of 20CrMnTi steel
In this study, the influences of carburization (followed by quenching and low-temperature tempering) followed by shot peening on “apparent” fatigue limits of 20CrMnTi steel specimens were studied and quantitat...

Effect of high pressure on glass transition in Zr-Ti-Cu-Ni-Be bulk metallic glass
A new method is developed to directly exhibit glass transition in Zr-Ti-Cu-Ni-Be bulk glass-forming alloy under high pressure in metallic glass. Via the method, we derive an increase of glass transition temper...
