Study Design: Near-term fetal sheep with implanted instrumentation underwent either sham occlusions (n = 8) or repeated brief umbilical cord occlusions (n = 12) continued until the onset of severe (<20 mm Hg) or sustained hypotension.
If threatened, Caribbean reef sharks sometimes perform a threat display, in which they swim in a short, jerky fashion with frequent changes in direction and repeated, brief (1 1.2 second duration) drops of the pectoral fins.
On the contrary, repeated brief bouts of separation increase foals' sensitivity to maternal separation [e.g. 5*10 min., 55], as for humans and non-human primates [48], [49].
Starting from a resting level of 3 mM glucose, repeated brief applications of 11 mM glucose elicited reproducible cAMP responses with little potentiation or attenuation in successive trials (Figure 4B).
Repeated brief isoflurane anaesthesia induces focal cerebral ischaemia tolerance in rats in a dose response manner.
Repeated brief cessation advice has been shown to be a feasible and inexpensive addition to routine TB case management [ 20].
Participants then performed repeated, brief (~5 s) isometric maximal voluntary contractions (MVC) of the quadriceps, each separated by a minimum of 90 s of rest.
Underlying the chronic relapse risk may be negative neuroplastic changes in the brain, caused by the cycle of continued alcohol abuse, repeated brief alcohol abstinence, and alcohol withdrawal.
The present study was designed to examine the role of ischemic-preconditioning (repeated brief periods of ischemia, IPC) in prevention of renal injury caused by ischemia-reperfusion (IR) in rats.
These may suggest that, unlike the I/R model, in which the tissue undergoes repeated brief ischaemic episodes, the acute ischaemia is associated with a more extensive injury that is not completely dependent on ROS generation.
