The function of the endogenous pain inhibitory systems in humans can be assessed by conditioned pain modulation (CPM) paradigms [28].
Pain from repeated algometer pressures increased more in the CTTH sufferers compared with healthy controls, both at finger and shoulder, and was less inhibited by conditioned HNCS [141].
Biological tissues and fluids can be sampled on a regular basis from the dolphins for accumulation of tissue residues, facilitated by conditioned husbandry behaviors.
These results prove that upregulation of PTEN in glioma cells by conditioned media from co-cultured glioma and hUCBSC cells inhibit spheroid migration.
The residual chemotactic activity of pre-osteoblastic MC3T3-E1 cells by conditioned media of siRNA-treated osteoclasts most likely reflects the presence of low amounts of PDGF-bb secretedcreted by these cells.
Neurons were then incubated for 30 minutes, washed by conditioned neurobasal medium and then 100 µM NMDA for 3 minutes was applied to stimulate the extrasynaptic population of NMDA receptors.
This notion is supported by the finding that injections of amphetamine into the nucleus accumbens facilitate action in the presence of or rewarded by conditioned incentive stimuli [10] [12], whereas 6-hydroxydopamine lesions of the accumbens reduce these actions [13].
