Morphological Aspects of Ciliary Motility
In Elliptio complanatus lateral cilia, two distinct patterns of filament termination can be discerned. In one case, all nine filaments are present and all are single; in the second, at least one filament is missing but doublets are still present. These probably represent different configurations within one cilium in different stroke positions; to get from one to the other, some peripheral filam...
متن کاملComputer modelling of ciliary motility.
This article is devoted to mathematical modelling of motility of a single cilium. After some simplifications, a mechanical model of a cilium as well as a mathematical model of the mechanism of ciliary motility were proposed. These models are based on the hypothesis which was formulated earlier.
متن کاملFlagellar and ciliary beating in trypanosome motility.
The single flagellum of Leishmania and Trypanosoma parasites is becoming an increasingly attractive model for the analysis of flagellar function-driven largely by the abundance of genomic and proteomic information available for the organelle, the genetic manipulability of the organisms and the importance of motility for the parasite lifecycle. However, as yet, there is a paucity of published da...
متن کاملDifferential regulation of Paramecium ciliary motility by cAMP and cGMP
cAMP and cGMP had distinct effects on the regulation of ciliary motility in Paramecium. Using detergent-permeabilized cells reactivated to swim with MgATP, we observed effects of cyclic nucleotides and interactions with Ca2+ on the swimming speed and direction of reactivated cells. Both cAMP and cGMP increased forward swimming speed two- to threefold with similar half-maximal concentrations nea...
متن کاملEffect of ciprofloxacin on ciliary motility of rabbit airway epithelium.
To determine the effect of the new quinolone ciprofloxacin on airway ciliary motility, we studied ciliary beat frequency (CBF) of rabbit tracheal epithelium using an in-vitro microphoto-oscillation method. Incubation of the cells with ciprofloxacin increased CBF in a concentration-dependent manner, the maximal increase from the baseline value and the EC50 being 17.1 +/- 2.0% (P < 0.01) and 10(-...
