The quality of psychomotor activity has often been described as a correlate of psychological well-being or illness. In this paper a theoretical position is described regarding the planned use of psychomotor activity as a therapeutic vehicle. Specifically, psychomotility is viewed as a tool to help bring about increased organization of thought processes

Swarming involves differentiation of vegetative cells into hyperflagellated swarm cells that undergo rapid and coordinated population migration across solid surfaces. Cell density, surface contact, and physiological signals all provide critical stimuli, and close cell alignment and the production of secreted migration factors facilitate mass ...

Cell Motility, 1983
AbstractWe have utilized a video‐enhanced contrast system coupled to a DIC‐equipped microscope to examine the motility of both whole coelomocytes and individual filopodia. When the cells are left in diluted coelomic fluid, they exhibit a fibroblast‐like mode of translocation across the substrate.

Spirochetes are bacteria distinguished by an undulate or helical cell body and intracellular flagellar called periplasmic flagella or endoflagella. Spirochetes translate by rotating the cell body. In this chapter, we show a method for simultaneous measurement of the cell body rotation and swimming speed in individual spirochete cells.

A new cryo-EM structure of the bacterial flagellar hook, which connects the motor to the flagellar filament, reveals 11 distinctive conformations of the subunit. The cooperative dynamic switching among these states offers a dramatic extension of two-state models of protein allostery.

Current Opinion in Gastroenterology, 1997
Several major themes emerged over the past year in the area of gastroduodenal motility. Mostly, these themes represented extensions of research areas discussed in prior reviews in this series rather than the emergence of completely new concepts. Thus, for example, considerable emphasis has again been placed on regional gastric motor function in ...

This review covers the recent advances that have been made in intestinal motility. Failure to stimulate the cephalic response when enteral tube feeding via the nasogastric route is important in contributing to enteral tube feeding related diarrhoea, which cannot be initially overcome by the use of fibre containing feeds.

Abnormalities of gastroduodenal motility are considered key players in the pathogenesis of upper gastrointestinal symptoms in disorders such as functional dyspepsia and gastroparesis. Abnormalities of sensory control are considered another important factor that contributes to symptom generation.
