Perception Of Illness And Its Association With Willingness To Adhere To Treatment In Chronic Hepatitis C Patients With New Diagnosis Of Nonalcoholic Fatty Liver Disease, Carmel Kruse

The Eleanor Mann School of Nursing Student Works

Chronic liver disease is becoming the most common cause of mortality, morbidity, and utilization of healthcare services globally. Both nonalcoholic fatty liver disease (NAFLD) and chronic hepatitis C (CHC) are frequent causes of chronic liver disease. Recently, there have been significant findings on the relationship between NAFLD and CHC; patients with CHC have a higher incidence of NAFLD. The introduction of direct-acting antivirals has cured more CHC patients than ever before. Unfortunately, the current interventions for NAFLD requiring behavioral change remain ineffective. Patient’s ability to follow advice depends largely on their health beliefs; therefore, understanding their illness perception is an …

Expression Of Claudins In Gill And Opercular Membranes In Relation To Osmoregulation In Euryhaline Atlantic Killifish, Fundulus Heteroclitus, Allison Mcfarland

Graduate Theses and Dissertations

Atlantic killifish (Fundulus heteroclitus) are euryhaline teleosts, which means they can thrive in environments with varying salinities, ranging from concentrated seawater (SW) to dilute fresh water (FW) and thus survive in estuaries. To be able to maintain ionic and osmotic homeostasis in these diverse salinities, osmoregulatory organs like gill and opercular membrane must be able to adjust the permeability and transport of water and ions. The surface epithelia in these organs need to prevent the passive flux of ions and water in a drastically changing environment, while being able to switch between active ion secretion or uptake dependent upon environmental …

Examining The Effects Of Oral Contraceptive Use On Thermoregulation, Whitley C. Atkins

Graduate Theses and Dissertations

Purpose: The purpose of this investigation was to evaluate the effects of combined (estradiol and progestin) monophasic oral contraceptive pill (OCP) use on thermoregulation. Further, we sought to evaluate OCP use on acute rehydration post-exercise in the heat using recommended rehydration guidelines. Methods: Twelve healthy, aerobically trained (VO2peak = 47.8 ± 4.7 mL/kg/min), long term female oral contraceptive users completed a familiarization trial and two experimental days separated by ≥ 7 days. The two experimental trials were identical except for the hormone dosing phase. One trial was completed during the third week of active pill dosing (ACT) and one during …

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 …

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 …

Implementing An Exercise Referral Scheme For Promoting Physical Activity In University Mental Health Care, Bryce Daniels

Graduate Theses and Dissertations

Introduction. Mental health symptoms and conditions are prevalent and increasing on college campuses with anxiety and depression having the highest increases in prevalence. Many college students are also physically inactive which is problematic as physical activity benefits mental health. Exercise referral schemes (ERS) can promote physical activity, though no studies have investigated the implementation of an ERS within a college counseling center. Purpose. The purpose of this dissertation was to investigate the implementation of an ERS for promoting physical activity in university mental health care. Methods. Study 1 used a qualitative descriptive design of 14 certified counselors to explore perceptions …

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 …

Effects Of Exercise On Parkinson's Symptom Relief, Brooke Burnett

The Eleanor Mann School of Nursing Undergraduate Honors Theses

In this review of twenty research articles, the effects of moderate exercise therapy on the symptoms of Parkinson’s Disease will be explored. Appropriate literature was located using the research question, “In older adults with a Parkinson’s Disease Diagnosis, how does moderate exercise influence the symptoms of this disease?” Twenty peer-reviewed research articles were examined for the impact of different forms of exercise on various symptoms associated with Parkinson’s. Nineteen of the articles reviewed provide substantial evidence in support of exercise therapy as a treatment option for people with Parkinson’s, and one of the articles found inconclusive evidence neither in support …

Preparation Of Proteins And Peptides From Heat-Stabilized Defatted Rice Bran Via Solid State Fermentation And Investigating For Skin Health, Ali A. Bisly

Graduate Theses and Dissertations

Heat-stabilized defatted rice bran (HDRB) is an abundant and inexpensive agro-industrial by-product of rice milling and rice oil extraction process. Furthermore, HDRB is a potential source of proteins. However, the direct protein extraction has low yield of protein due to the impact of heat stabilization and oil extraction process which made the HDRB proteins bound and interact with other components. This research is based on using solid-state fermentation (SSF), which is a natural and cost-effective approach to facilitate protein extraction from HDRB using Bacillus subtilis (natto) Takahashi as a microorganism.

Response surface methodology (RSM) analysis was used with Box-Behnken design …

Effects Of Sunrise/Sunset Lighting On Corticosterone Levels In Coturnix Quail (Coturnix Coturnix), Hannah M. Feuerborn, Sara K. Orlowski

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Both genetics and environment play important roles 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. The current study aimed to evaluate the impact of genetics and the effect of sunrise/sunset lighting on the stress response of 4 genetic lines of Coturnix quail. The 4 lines utilized in this study included high stress (H), low stress (L), stress control (R), and Arkansas randombred (A) quail lines. Day old chicks from these lines were placed in one of two environmentally controlled rooms. …
