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

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 ...

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.

Nature Structural & Molecular Biology, 2019
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.

To review recently published studies presenting novel and relevant information on small intestinal motility.The reviewed studies covered a variety of topics with several themes emerging. Our understanding of the influence of systemic disorders, intestinal and extraintestinal infections and enteric bacteria on digestive motor function continues to ...

Actin-dependent motile forces and cell motility
Current Opinion in Cell Biology, 1994Force arising from actin polymerization and myosin activity drives a number of different actin-based cell movements. Several new reports support previous data suggesting that actin polymerization drives lamellipodial protrusion and bacterial propulsion, and one report describes a more indirect role for actin assembly in axonal elongation. The major new

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 ...

Podocytes, the postmitotic and highly branched epithelial cells of the glomerulus, play a pivotal role for the function of the glomerular filtration barrier and the development of chronic kidney disease. It has long been discussed whether podocytes in vivo are motile and can laterally migrate in a coordinated way along the capillaries until they reach ...
