The Neuroinflammatory Effects Of Chronic Unpredictable Stress On Zebrafish, Danio Rerio, Brandon Stewart
The Neuroinflammatory Effects Of Chronic Unpredictable Stress On Zebrafish, Danio Rerio, Brandon Stewart
Master of Science in Integrative Biology Theses
Stress is a state of threatened homeostasis counteracted by various physiologic and behavioral responses aimed to maintain or restore balance. As such, stress acts as a motivator to perform during the challenges of life to survive. Chronic perturbations to the stress response homeostasis without relief can lead to dysregulation, thus attenuating organ systems and structures and causing significant damage {1]. Individuals who undergo psychological trauma endure an acute and transient experience, which results in minimal functional impairment, but some suffer from a chronic condition called posttraumatic stress disorder (PTSD). Individuals who have PTSD are likely to experience intense stress, …
Hormonal Responses To Seasonal Thermal And Ecological Stressors In Japanese Macaques (Macaca Fuscata), Lilianne Nelson
Hormonal Responses To Seasonal Thermal And Ecological Stressors In Japanese Macaques (Macaca Fuscata), Lilianne Nelson
Masters Theses
Relative to most primate species, Japanese macaques (Macaca fuscata) experience extreme seasonal variation in thermal and ecological stressors that can impact energetic demands. To cope with these environmental changes, levels of metabolic hormones, such as cortisol and triiodothyronine, fluctuate to facilitate energetic adjustments. While previous research in primates has investigated thermal and ecological stressors individually, a combined assessment of these stressors alongside hormone levels can provide a more holistic understanding of the relationship between a primate’s thermoregulation, energetic balance, and stress. The goals of this study were to determine the effects of season, temperature and ecological stress on …
Predictors Of Psychosocial And Physiological Distress In Colorectal Cancer Patients, Hyrum Eddington
Predictors Of Psychosocial And Physiological Distress In Colorectal Cancer Patients, Hyrum Eddington
Undergraduate Honors Theses
Distress among cancer patients has been broadly accepted as an important indicator of patient well-being. However, questions remain such as what patient characteristics are associated with high distress and whether patient-reported distress is correlated with distress biomarkers. To answer these questions, we performed a survey study of 238 colorectal patients in which we assessed patient-reported distress, possible contributors to that distress, and patient anxiety and depression. We also abstracted demographic and clinical information from patient charts and collected measures for salivary cortisol and sarcopenia. We conducted bivariate statistical analyses between patient demographics, clinical factors, and psychosocial measures with our three …
The Effect Of Slow-Feeding Hay Nets On Post-Prandial Equine Salivary Cortisol Levels, Grace Simpson
The Effect Of Slow-Feeding Hay Nets On Post-Prandial Equine Salivary Cortisol Levels, Grace Simpson
Undergraduate Honors Thesis Projects
Throughout its evolution, the Equus caballus, or horse, developed a physiological response to environmental alterations involving the synthesis and release of cortisol from the hypothalamic-pituitary-adrenal axis, to regulate blood glucose levels, vascular tone and hormone release throughout the body (Ambrojo et al., 2018). With a hypothesis that changing a horse’s feeding method can alter salivary cortisol levels, the aim of this research project was to determine if feeding forage to horses in slow-feeding haynets would significantly reduce acute cortisol salivary level fluctuations, which would be valuable to minimize horses’ stress and increase overall welfare. Two feeding methods …
Effect Of The Prospect Of Transport On Captive Tiger Behavior And Fecal Cortisol In Naïve And Experienced Tigers, Callan Lichtenwalter
Effect Of The Prospect Of Transport On Captive Tiger Behavior And Fecal Cortisol In Naïve And Experienced Tigers, Callan Lichtenwalter
Graduate Theses and Dissertations
With close to 5,000 captive tigers in the United States, it is vital to ensure that these tigers are receiving adequate welfare whether they are in an accredited facility, or privately owned. The goal of this study was to assess whether captive tigers at a rescue facility with experience being transported outside of the facility would respond differently to the presentation of their transport vehicle than their naïve counterparts who had only been transported within the facility. The behavior of 5 naïve and 7 experienced tigers (n = 12) located at Turpentine Creek Wildlife Refuge in Eureka Springs, Arkansas was …
Identifying Metabolites As Markers Of Fatigue In Athletes, Christopher D. George
Identifying Metabolites As Markers Of Fatigue In Athletes, Christopher D. George
Honors Theses
Fatigue in athletes caused by inadequate rest and other stressors can be severely detrimental to their health, and yet there is no reliable way to measure and track fatigue. Many classical measures of fatigue like body mass and resting heart rate are not reliable ways to track the physical fatigue of an athlete because they can change with many factors. In addition, it is not known how academic stress on top of physical stress affects fatigue. Metabolomics is a relatively new area of study and tracking metabolites offers the possibility to produce biomarkers to assess fatigue. This study collected saliva …
