Developing A Novel Place Preference Assay To Compare Drosophila Species Over Time, Martha M. Brinson
Honors Theses
Across phylogeny, integration of external factors, memory, and internal states of the organism dictate organismal behavior and mechanisms. The underlying genetic components can affect these behaviors such as in genomic changes arising from speciation. In this thesis, a new place preference assay was evaluated in the analysis and investigation of two species of Drosophila flies (D. melanogaster and D. simulans) to measure similarities and differences and their attraction to two different food substrates. Sleep and circadian measurements were also recorded during experimentation. The Drosophila Activity Monitor 5M (DAM5M) System and Sleep Circadian Analysis MATLAB Program (SCAMP) analysis were …

Linking Spinal Cord Circuits With Upper Limb Sensorimotor Control In Adults With Cerebral Palsy, Saihari Dukkipati
Theses & Dissertations
Cerebral palsy (CP) is the most common neurological disorder originating in childhood, but most of the people living with CP are currently adults. While people with CP continue to get older, the amount of research focused on adults has been rather limited. The early childhood insults leading to CP are thought to originate in the brain, but the effects on the entire neuromuscular system across the lifespan have only recently started to be explored. Of note, recent neuroimaging evidence suggests that the cervical spinal cord structure is atypical in adults with CP. However, it is largely unclear how the neurophysiological …
The Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting,

The Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting, Geoffrey Reliquias
Honors Theses
Previous research has indicated that aspects of cognitive inhibition may be enhanced after engaging in acute exercise. Notably, cognitive inhibition has been theorized as a potential mechanism for a form of active forgetting known as retrieval-induced forgetting (RIF). Given that cognitive inhibition may explain the RIF phenomenon, and is also influenced by exercise, it is plausible that acute exercise may directly influence RIF. To our knowledge, only one study has examined whether acute exercise has an effect on RIF. The findings of that study did not find a statistically significant effect for RIF; however, we believe that the rather small …

Psychological Trauma Alters T-Lymphocyte Inflammation And Redox Through Sympathetic Mechanisms, Safwan K. Elkhatib
Theses & Dissertations
Posttraumatic stress disorder (PTSD) is a devastating psychiatric disorder characterized by distinctive symptom clusters, including intrusive memories (i.e., flashbacks), avoidance of related stimuli, affective changes, and hyperarousal. Strikingly, patients with PTSD face a significantly increased risk for a number of inflammation-driven pathologies, ranging from cardiovascular to autoimmune disease. Yet, the exact etiology of this increased risk remains unknown. The immune system is known to be strongly influenced by the sympathetic nervous system, and sympathetic overactivity is a hallmark of PTSD. Lymphoid organs, such as the spleen, are richly innervated by sympathetic nerve fibers which terminate near adaptive immune …

Role Of Fasting In Caloric Restriction Improved Glucose Tolerance, Makayla M. Dillon
ETD Archive
The Caloric Restriction (CR) diet in mammals has been shown to increase longevity and prevent metabolic disorders. Some of the benefits of CR include improved glucose homeostasis, namely improvements in glucose tolerance. Mice on the CR diet have a 30% reduction in food provided, as well as a fasting period between meals as they are only fed once a day. Hence the benefits of CR stem from both fasting and reduced calorie intake. In this study, we investigated if the fasting component of CR is responsible for the benefits of this diet in improving glucose homeostasis. In particular, we used …

Ankle Dorsiflexion Range Of Motion, Dynamic Balance, And Static Balance In Division Iii Collegiate Gymnasts, Emily Sabo
Master's Theses
Introduction: Artistic gymnastics is a demanding sport composed of high intensity activities. Decreased range of motion can increase the risk of lower extremity injury due to the inability to disperse forces properly upon landing. Landing from a height demands dynamic balance, which may be influenced by ankle range of motion. Due to the complexity of the sport, identifying potential deficits at the ankle could lead to the development of injury prevention programs. Purpose: The purpose of this study is to investigate if correlations exist between active ankle dorsiflexion range of motion (AROM) and static balance and/or AROM and dynamic balance …

Effects Of Sunrise/Sunset Lighting On Corticosterone Levels In Coturnix Quail (Coturnix Coturnix), Hannah Feuerborn
Poultry Science Undergraduate Honors Theses
Both genetics and environment play an important role in the growth, performance and overall welfare of poultry species. Current commercial production practices typically do not mimic the natural environmental conditions of ancestral poultry species, specifically lighting requirements. In nature, poultry species are subjected to natural day length and the slow rising and setting of the sun. This is compared to commercial conditions in which lights are sudden on/off, not mimicking the natural trajectory of the sun in terms of light intensity and exposure. The current study aimed to evaluate the impact of genetics and the effect of sunrise/sunset lighting on …

Effects Of Glucocorticoids Upon Pro-Inflammatory Responses To Acute Sleep Fragmentation, Hunter Weaver
Masters Theses & Specialist Projects
Sleep loss is a common problem in humans who suffer from obstructive sleep apnea. Sleep aids in the regulation of immune responses, some of which induce inflammatory responses. Cytokines regulate the inflammatory process and are released in response to sleep fragmentation (SF) in mice. Glucocorticoids are hormones that are released from the adrenal cortices during a stress response and are considered to be anti-inflammatory and immunosuppressive at high doses but may stimulate immune function on an acute level. The first hypothesis tested was that normal physiological expression of glucocorticoids (Sham) will display increased IL-1β and TNFα expression levels, while high …
Effects Of A Leucine Supplementation On Mitochondrial Markers In Pre-Cachectic Female Mice,

Effects Of A Leucine Supplementation On Mitochondrial Markers In Pre-Cachectic Female Mice, Breanna Williams
Biological Sciences Undergraduate Honors Theses
Cancer cachexia is a wasting syndrome characterized by extreme weight and skeletal muscle loss that results in death in many tumor bearing individuals. Because skeletal muscle requires a high amount of energy to function, skeletal muscle fiber cells need healthy mitochondria to function. When skeletal muscle loss atrophy occurs, the mitochondrial network is degraded. Different treatments for this muscle atrophy are being studied, one of which is a leucine supplementation since leucine has been found to stimulate skeletal muscle growth in other studies. However, current data suggests that a leucine supplementation in cachexic individuals exacerbates this atrophy. PURPOSE: This study …

Evaluation Of Diaphragmatic Movement In The Respiratory System Of An Emphysema Patient, Aubri Ford
Honor’s College Freeman Research Journal
Respiration is an essential part of life. The diaphragm is the main muscle involved in the process of respiration. However, respiratory diseases such as emphysema alter the function of the diaphragm which sometimes leads to respiratory failure and death. This review compiles studies concerning emphysema and how the morphological changes in the lungs (i.e. hyperinflation) caused by the disease affect the diaphragm. The first major point covers the risks associated with developing the disease as a component of Chronic Obstructive Pulmonary Disease (COPD). Next, the paper outlines the pathophysiology of emphysema within the lungs, the methods used to diagnose emphysema, …

The Influence Of Temperature And Body Size On Food Consumption In Prairie Lizards (Sceloporus Consobrinus), Morgan Pelley
Biological Sciences Undergraduate Honors Theses
Understanding the effect of temperature on physiological and digestive processes, such as voluntary consumption rate, is critical for assessing the impact of climate change. Food consumption is required for lizard survival and reproduction and its rate is dependent on temperature. For ectotherms, as temperatures increase, the amount of food consumed to meet the energy requirements related to survival and reproduction must also increase. Information on the amount of food voluntarily consumed may aid in determining if lizards can meet energy requirements. Such information could also aid in predicting survival of lizard populations, through construction of predictive climate change models. In …

Small mammals in hot deserts often avoid heat via nocturnality and fossoriality and are thought to have a limited capacity to dissipate heat using evaporative cooling. Research to date has focused on thermoregulatory responses to air temperatures (Ta) below body temperature (Tb). Consequently, the thermoregulatory performance of small mammals exposed to high air temperatures is poorly understood, particularly responses across geographic and seasonal scales. We quantified the seasonal thermoregulatory performance of four cricetid rodents (Neotoma albigula, N. lepida, Peromyscus eremicus, P. crinitus) exposed to high Ta, at four sites …

Influences Of Drosophila Circadian Clock On Sugar-Mediated Physiological Changes, Erica E Hassoun
College of Arts & Sciences Senior Theses
It is widely known that high sugar consumption and poor sleep are detrimental to human health. Both are risk factors for obesity, which can lead to conditions such as heart disease. Despite this connection between sugar and sleep, little is known about how circadian clock dysfunction affects the physiological changes caused by increased sugar consumption. In this thesis, a mutant line of the model organism Drosophila melanogaster (ClkJrk, which contains a nonfunctional circadian rhythm gene known as Clk) that leads to circadian dysfunction, was exposed to a high sugar diet to observe how Clk affects sugar-related changes to …
