The Effect Of Circadian Rhythm On Cortisol And Perceived Stress Correlations, Adam Bender
The Effect Of Circadian Rhythm On Cortisol And Perceived Stress Correlations, Adam Bender
Honors Theses
Stress is a known trigger of the Hypothalamus-Pituitary-Adrenal (HPA) Axis which leads to the production and secretion of the catabolic steroid cortisol by the adrenal gland. Since cortisol production is affected by stress, it follows that a high self-perception of stress would be correlated with high blood and saliva cortisol levels. Literature generally shows a gap in identifying this correlation, perhaps because of the interconnected nature of endocrine pathways. New experimental methods that control for the effects of circadian rhythm have shown limited success in demonstrating this correlation. Our purpose is to continue exploring the relationship between cortisol, perceived stress, …

Restraint Stress Alters Pro-Inflammatory Cytokine Expression And Increases Superoxide Dismutase In The Rat Hypothalamus And Hippocampus, Kristina Isabel Barron
Open Access Theses & Dissertations
The impact of restraint stress on changes in cytokine expression and oxidative stress markers in hippocampal (Hipp) and hypothalamic (Hyp) regions of the brain, were assessed in a rat model. In addition, immune and inflammatory variables were assessed in peripheral blood. Male Wistar rats were acutely (30 min) or repeatedly (30 min/d for 14 consecutive days) exposed to a restraint stress, or maintained as non-stressed controls. At the time of sacrifice, whole blood and brain tissues enriched in Hyp or Hipp regions were collected; blood was collected with EDTA as an anticoagulant and centrifuged to yield plasma. All tissue samples …
