Tendon gliding exercises.
An exercise program for tendon gliding is introduced for use in hand treatment and rehabilitation. The program incorporates thumb range of motion and three basic fist positions: book, fist, and straight fist. The anatomic and experimental basis of this program is discussed. The exercises allow the flexor tendons to glide to their maximum potential and can greatly facilitate therapeutic activiti...
متن کاملChemotaxis in a gliding bacterium.
Myxococcus xanthus cells exhibit directed motility up phosphatidylethanolamine (PE) gradients, and we suggest that PE behaves as a chemoattractant. Computer-assisted stop-motion digital microscopy was used to record cell movements in slide culture. PE decreased cellular reversal frequency with molecular specificity that was correlated with the fatty acid composition. Synthetic dilauroyl (di C12...
متن کاملGliding ghosts of Mycoplasma mobile.
Several species of mycoplasmas glide on solid surfaces, in the direction of their membrane protrusion at a cell pole, by an unknown mechanism. Our recent studies on the fastest species, Mycoplasma mobile, suggested that the gliding machinery, localized at the base of the membrane protrusion (the "neck"), is composed of two huge proteins. This machinery forms spikes sticking out from the neck an...
متن کاملGliding spline motions and applications
We consider the ICP (iterative closest point) algorithm, which may in general be used for moving ‘active’ elements such as curves and surfaces towards geometric objects whose distance field is computable. We show how it may be accelerated, and how it can be applied to the design of near-Euclidean near-contact spline motions. One particular application of this concept is the modeling of milling ...
متن کاملDissipative shocks behind bacteria gliding.
Gliding is a means of locomotion on rigid substrates used by a number of bacteria, including myxobacteria and cyanobacteria. One of the hypotheses advanced to explain this motility mechanism hinges on the role played by the slime filaments continuously extruded from gliding bacteria. This paper solves, in full, a non-linear mechanical theory that treats as dissipative shocks both the point wher...
