Besides the obvious ethical obligation to provide adequate analgesia and sedation for painful and stressing procedures, there is evidence of the negative effects of both: too deep and too shallow levels of sedation [ 6, 7].
Each stressing procedure started at 10 00 a.m.
The rats were subjected to social instability stress procedure for 15 days.
Lagrange finite element suffers from higher order stress gradient oscillations due to Gibbs phenomenon and require alternative stress recovery procedures for accurate interlaminar stress calculations, especially interlaminar normal stress.
The stress procedure lasted for 4 weeks prior to the behavioural testing.
Mean duration of movement was significantly elevated, in anhedonic animals only, during the dark phase of the day/night cycle between days 14 and 21 during the stress procedure and for at least 14 days after termination of the procedure; no differences between the groups are observed during the light phase.
During administration of the experimental stressor, physiological reactivity was either assessed at specific time points (in three studies) [ 35, 41, 42], or continuously throughout the stress procedure (only for autonomic measures such as heart rate, blood pressure and/or skin conductance; in four studies) [ 29, 32, 37, 45].
For the stress procedures, air stress was performed by using compressed air which traveled through Tygon tubing (1/4 × 1/16 inch) connected to a Pasteur pipette and the air was directed into the face of the rat at a pressure of 10 psi for 30 seconds.
It should be stressed, however, that the procedures for faecal examination of buffaloes in the Philippines are different from those employed in China.
Similar to differences in baseline values, group differences of mean values during the complete psychosocial stress procedure were found for SBP in males, EHRV, and alpha-amylase for males.
