IL-17A belongs to the interleukin family and its expression has been demonstrated in later phases of recovery stroke
, with IL-17A from astrocytes thought to maintain and augment ischemia-induced neurogenesis and long-term functional recovery.
An extension of this hypothesis is that the cilium takes the particle inward with its recovery stroke toward the lateral edge of the velum, where the particle is subsequently moved into the food groove.
In these observations, the capturing cilium was in its straight effective stroke and then began its recovery stroke while in contact with the particle (see video clips #243 and #244, http://www.
This response time is much less than their estimated duration of > 100 ms for a single beat cycle of effective and recovery stroke in forward beat.
The motion of the algal cell and the curvature of recovery strokes indicated the beginning of reversed beat.
As the power stroke ends and the recovery stroke
begins, these long setae collapse from a fan into a tight bundle.
Rafts of mucus and embedded particles were transported atop a periciliary space traversed by frontal cilia, which engaged the mucus layer and moved it during the effective stroke, disengaging and completing the cycle during the recovery stroke
Often, one arm was flexed while another on the same animal was in its recovery stroke
Figure 6 compares the symmetrical stroke of the model (where the fan of thin brass rods is unable to flex during the recovery stroke
) with the asymmetrical stroke of the same frequency and speed (where the fan is free to flex during the recovery stroke
and then opens passively during the course of the power stroke).
a], of the limb perpendicular to the body axis at the 90 [degrees] position during the power stroke and the recovery stroke
and computed the ratio of the two areas.
cementarium at 125 and 500 frames per second demonstrated that the effective strokes of prototroch and metatroch are toward each other and the recovery strokes
are away from each other (Fig.
