Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells
FEBS Open Bio, EarlyView.To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Pneumatic Automation Tools: Pneumatic Muscle
Mechanical Engineering and Computer Science, 2017 The traditional actuating motor for pneumatic drives is a differential double-acting pneumatic cylinder used to create a pushing force that is significantly larger than the pulling force. The pneumatic muscle is a single-acting operating motor to be used for creating a pulling force.
