Introduction: Renin angiotensin system has an important role in blood pressure and renal functions. Active angiotensin-converting enzyme 2 converts angiotensin I into angiotensin-(1-7) which is a vasodilator hormone and interacts with nitric oxide changes as well as other angiotensin II receptors. In this study we evaluated the role of Mas receptor antagonist (A779) and renal perfusion press...

Living organisms can sense extracellular forces via mechanosensitive ion channels, which change their channel conformations in response to external pressure and regulate transport through the cell membrane. Such pressure-regulated is critical for various biological processes, such as cellular turgor control hearing mammals, but has yet be achieved artificial systems using similar mechanisms. In...
