Apoptosis induced by inhibition of cyclic AMP response element-binding protein in vascular smooth muscle cells.

abstract：:Direct examination of the aortic orifice at the level of the aortic valves (aortic valvular orifice area, AVOA) in the short-axis plane was performed with a 3 MHz two-dimensional pulsed Doppler echocardiographic apparatus. The AVOA was mapped with the Doppler gate to detect or rule out the presence of a regurgitant ao...
