Sentence examples for rotation rod from inspiring English sources
After a transmission scan for 15 min using a 68Ge-68Ga rodation rod source, 18F-BCPP-BF at ca. 15 MBq was intravenously injected into each rat via the tail vein, and this was followed by an emission scan with list mode data acquisition (every 1 ms) for 90 min.
The latency to fall off the rotating rod per rotation speed level was recorded as a measure of motor function.
After the training session, mice were placed on the rotating rod with a linear increase in rotation speed from 2.5 to 48 rpm over a 5-min period.
Mice were placed on the middle of the rotating rod, its body axis being perpendicular to the rotation axis, and its head against the direction of rotation.
The speed of rotation was gradually increased (0,3 rpm/sec) and the rodent's ability to remain on the rotating rod (time to the first fall) was recorded.
The treated mice and the untreated MPSII and wild-type mice were placed on top of the rotating rod facing away from the experimenter, in the orientation opposite to that of the rod rotation.
However, the rotation time for animals in the treated group was not comparable to the wild type controls, which were able to stay on a rotating rod for the maximum testing period (180 s).
The apparatus consisted of a horizontal motor-driven rotating rod in which the animals were placed perpendicular to the long axis of the rod, with the head directed against the direction of rotation so that the hamster has to progress forward to avoid falling.
The rotation speed was increased every 30 sec by 4 rpm, with a maximum test duration of 5 min. Mice were scored on their latency to fall from the rotating rod.
Note that the observed differences cannot be attributed to passive rotation (grabbing the rod and rotating without having to ambulate) because this behaviour was not observed in either group in all the rota rod experiments.
The motion equations incorporate the effects of transverse shear strain and inertia of rotation of the rod's cross section.
