Unlike the calcium transient that subsequently led to ECM-guided cell movement, MnCl2 or DTT treatment stops locomotion and the cell remained stably adhesive to the FBN path for a long period of time (arrows, Fig. 2C, D and see Movie S5, 6).
Polymorphonuclear leukocytes have been enticed into a micropipette filled with chemoattractant [ 7], and by applying a known hydrostatic pressure to the pipette, a force of ~3 × 10−3 dyn was just sufficient to stop leukocyte locomotion.
As Adolph showed in a series of video exemplars, head-mounted eye tracking combined with video tracking reveals a complex set of overlapping activities, with quick switches within and between activities, changes in speed, and continual starts and stops in locomotion.
The temporal structure refers to the order of bouts of locomotion and stopping periods.
While many worms stopped moving altogether for up to 45 min, other worms displayed unproductive crawling often by propagating a single dorsoventral bend from head to tail before stopping or initiating backward locomotion.
The promising developments in the field of the capsule locomotion and stopping mechanisms [ 21– 23] will make it possible to place the capsule into gentle contact with the tissue when data are taken.
However, signs of behavior aging of NSG mice similar to these two strains and associated with reduced locomotion, increased episodes of stopping and starting, longer duration of food intake bouts were observed.
They were juvenile versions of this summer's fabled northern snakehead, a displaced Asian species feared by some and hyped by others for its ability to scarf down smaller fish and, in extremis, flop in primitive locomotion across dry land to its next food stop.
But they are a powerful, imaginative lobby for a version of American life that hasn't existed since the late 1950's and early 60's, when the national railroads' steam engines were retired, the interstate highways were built, air travel became common and the great golden age of locomotion and riding the rails rolled to a stop.
Based off of Eadweard Muybrige's stop-motion photography work from the late 1800s, which captured animals in locomotion, this piece aims to capture 3D change in this case, the three-step sequence of a bird spreading its wings for flight.
We came to their aid, tipped the churn and the frogs came out, one stopping temporarily on my hand, before their spring-heeled-Jack means of locomotion saw them shoot off into the undergrowth.
