It is also acknowledged that even small changes in the geometry of the valvular leaflets can induce significant changes in the intraventricular flow features.
From our simulations it appears that local segregation of charged lipids under the influence of the BAR dimer cannot produce high enough asymmetry between bilayer leaflets to induce significant bending.
For influenza A virus it has been demonstrated that virus scission is achieved by the M2 protein that is targeted to the edge of the assembly site and inserts an amphiphilic helix into the inner leaflet to induce membrane curvature (Rossman et al., 2010).
Cell-mediated retraction induces leaflet shortening that may be counteracted by the hemodynamic loading of the leaflets during diastole.
The presence of a leaflet prolapse often induces the choice of a composite graft repair.
Probably in concert with the paddle insertion into the outer leaflet, GTP-binding induces all large-scale conformational changes reported here to extend the molecule, exposing highly effective polymerization surfaces.
Soon after apoptosis is induced, PPS is translocated from the inner leaflet of the plasma membrane to the outer leaflet.
We next analyzed cell death through AV/PI staining and found that acetate induced exposure of phosphatidylserine to the outer leaflet of the plasma membrane in HCT-15 cells in a dose-dependent manner.
It was also noted that although the 0 mmHg group was fixed without transvalvular pressure, distention of the root induced significant changes in collagen structure of the leaflets.
Severe AR was induced by retrograde puncture of the aortic valve leaflets under echocardiographic guidance as previously described [ 16– 16].
