A portion of the transmitters (factor r) returns from the synaptic cleft into the presynaptic hair cell.
The atrioventricular septal defect had been effectively repaired, and the residual left atrioventricular valve had a deep "cleft" in its septal aspect.
These are arranged in two subdomains which are separated by the active site cleft.
There appears to be an increasing incidence of facial clefts over time.
There is no reason for intervention because of the facial cleft alone and any decisions should be made on accepted obstetric grounds.
These represented 3.4% of the total number of facial clefts (isolated and cases with multiple anomalies) and 9.4% of cases with multiple anomalies.
Clearance of glutamate in the synaptic cleft depends on passive diffusion and active uptake by glutamate transporters.
Males are more frequently affected with hare lip and cleft palate and pyloric stenosis while females are more prone to congenital dislocation of the hip.
