It was hypothesized that alterations in plasma concentrations of
corticosterone (CS) and prolactin (PRL) may be at least partially responsible
for polychlorinated biphenyl (PCB)-induced immunosuppression.
A 2 by 2 factorial experiment examined the interactions of PCB and P815,
an allogeneic tumor, on plasma concentrations of CS and PRL, and on...
In the wild, when an animal is exposed to predators or harsh conditions, the stress
response is often associated with fleeing behaviors, which are seen as increased
locomotor behavior. Handling-stress procedures and intracerebroventricular (icy)
injection of corticotropin-releasing factor (CRF) have both been shown to cause an
increase in locomotor activity...
The main objectives of the current study were to obtain the complete cDNA sequence of an opioid-like receptor from an amphibian, the roughskin newt, Taricha granulosa, and investigate the receptor's tissue distribution and regulation following chronic exposure to the glucocorticoid corticosterone (CORT). Degenerate primers designed in highly conserved regions of...
In nature, animals survive threats by responding physiologically and behaviorally in ways that are appropriate to the situation. Which responses are appropriate depend on the animals' surroundings and current physiological and behavioral state. This dissertation investigated the neuroendocrine mechanisms that control context-dependent behavioral responses to stress by focusing on the...
