Impact of Corticosterone and Zinc Deprivation on Memory and Hippocampal Functioning
… to examine the impact of long-term exposure to corticosterone (CC) and chronic zinc-deprivation (ZnD) on memory performance and hippocampal damage in rats. Previous work has examined the impact of exposure to CC or the impact of ZnD, but no previous work has examined the combined impact on …

Corticosterone as a mediator of the tradeoff between survival and reproduction
… are not fully understood. Stress-induced corticosterone is a strong candidate mechanism, because it is thought to promote survival-oriented behavior and physiology at the expense of non-critical functions such as reproduction. In this dissertation, I studied multiple components of …

Wintering white-throated sparrows (Zonotrichia albicollis): home ranges, aggression and corticosterone
… circulating levels of the stress hormone, corticosterone, to see if they paralleled behavioral changes. Concurrently, I validated identification of sparrow plumage morphs with genotype assays to determine reliability of field identification. I mounted study skins of white-throated sparrows …

Acute Sleep Fragmentation Induces Tissue-Specific Changes in Cytokine Gene Expression and Increases Serum Corticosterone Concentration
… various intervals of sleep fragmentation. Serum corticosterone concentration was also assessed. Sleep was disrupted in male C57BL/6J mice using an automated sleep fragmentation chamber (Lafayette Industries), which involved movement of a sweeping bar at specified intervals. Mice were exposed to …

Seasonal Variation in Corticosterone, Stress Responses, and Physiology in the Northern Cardinal <i>Cardinalis cardinalis</i>
… conditions and strong seasonality, however corticosterone (CORT, the main adrenal stress hormone) has not been studied with regards to changes in seasonal levels. I initially analyzed samples from cardinals collected between 2007-2011 from the Lake Thoreau Environmental Research and …

Sex Ratios and the City: Is parental corticosterone a mediator of the relationship between urbanization and offspring sex allocation?
… parental condition, and sex ratios is corticosterone (CORT), the primary glucocorticoid in birds. However, no research has examined the links between urbanization, individual condition, CORT, and adaptive sex allocation within the same study. Furthermore, research that has examined …

Immediate and enduring effects of corticosterone administration during adolescence and adulthood on anxiety and depressive behavior in male rats
… research has shown that the stress hormone corticosterone can increase depressive and anxiety-like behavior in rats as well as dampen the HPA response to a novel stressor (Kalynchuk et aI., 2004; Johnson et aI., 2006). Several studies have also shown that adolescence is a period of increased …

Effects of Stress, Circadian Rhythms, and Dietary Sodium on Brain Cell-Nuclear Uptake of Aldosterone and Corticosterone (Steroid Receptors)
… adrenal steroid hormones aldosterone (ALD) and corticosterone (CORT) in brain cell-nuclei has been implicated as a necessary step in the behavioral and physiological actions of these hormones. In vivo uptake of radioactively labeled ALD and CORT in adrenalectomized (ADX) rats indicates a strong …

Cell-mediated immunity in Marek's disease virus-infected chickens genetically selected for high and low levels of plasma corticosterone
… for either a high (HPC) or low (LPC) plasma corticosterone response to social stress, were inoculated with Marek's disease virus (MDV). Lymphocyte transformation (LT) microassays were performed to assess the CMI response of leucocytes from HPC and LPC MDV-infected chickens. Blastogenesis was …

ACUTE STRESS, BUT NOT CORTICOSTERONE, FACILITATES ACQUISITION OF PAIRED ASSOCIATES LEARNING ASSESSED IN RATS USING TOUCHSCREEN-EQUIPPED OPERANT CONDITIONING CHAMBERS
… of restraint stress (30 min) or injection of corticosterone (CORT; 3 mg/kg). Daily performance was then monitored for one week. We found that only the animals subjected to restraint stress performed with higher accuracy and task efficiency, when compared to untreated controls. These results …

Abiotic Factors Underlying Stress Hormone Level Variation Among Larval Amphibians
… abiotic factors influence stress hormones (corticosterone) in larval amphibians. Throughout the following chapters, I examined the effects of several abiotic factors on baseline and stress-induced corticosterone levels in the larvae of four amphibian species: Jefferson salamander (Ambystoma …

Stress hormones epinephrine and corticosterone modulate herpes simplex virus 1 and 2 productive infection and reactivation primarily in sympathetic, not sensory, neurons
… with the stress hormones epinephrine and corticosterone. Both sensory trigeminal (TG) and sympathetic superior cervical ganglia (SCG) neurons expressed adrenergic receptors and glucocorticoid receptor. In productively infected neuronal cultures, epinephrine treatment significantly …

Stress And Social Relationships: The Role Of Corticosterone In The Formation And Maintenance Of Pair Bonds In The Monogamous Zebra Finch (taeniopygia Guttata)
… explored the relationships between circulating corticosterone, neural expression of corticotropin releasing hormone and glucocorticoid receptors, social preference and pair bonding using a model species uniquely suited to studying long-term, monogamous relationships.</p>

The Role of the Pituitary-Adrenal Axis in G-CSF Therapy after Neonatal Hypoxia-Ischemia
… level of adrenocorticotropic hormone (ACTH), and corticosterone is increased after a brain insult. These hormones are the effectors secreted respectively by the pituitary and adrenal glands. It has been shown that the down-regulation of corticosterone levels can improve detrimental outcomes …
