Effects of inescapable shock upon subsequent escape and avoidance responding.
Exposure of dogs to inescapable shocks under a variety of conditions reliably interfered with subsequent instrumental escape-avoidance responding in a new situation. Use of a higher level of shock during instrumental avoidance training did not attenuate interference; this was taken as evidence against an explanation based upon adaptation to shock. Ss curarized during their exposure to inescapab...

Administration of bacterial endotoxin (lipopolysachharide; LPS) elevates proinflammatory cytokines, such as interleukin-1beta (IL-1beta) and IL-6, and activates the hypothalamic-pituitary-adrenal (HPA) axis. Corticosterone (CORT), the glucocorticoid (GC) effector hormone of the HPA axis in rats, inhibits both proinflammatory cytokine production/release and activity of the HPA axis itself. Expos...
متن کاملFailure to escape traumatic shock.
Dogs which had 1st learned to panel press in a harness in order to escape shock subsequently showed normal acquisition of escape/ avoidance behavior in a shuttle box. In contrast, yoked, inescapable shock in the harness produced profound interference with subsequent escape responding in the shuttle box. Initial experience with escape in the shuttle box led to enhanced panel pressing during ines...

Objective(s): Radiotherapy is one of the most effective modalities of cancer therapy, but clinical responses of individual patients varies considerably. To enhance treatment efficiency it is essential to implement an individual-based treatment. The aim of present study was to identify the mechanism of intrinsic apoptosis pathway on radiosensitivity and normal tissue complications caused by the ...
