The Biochemical And Metabolic Impact Of 8-Weeks Of Intermittent Energy Restriction On Resistance-Trained Adults: A Pilot Study, Dillon Wells

Masters Theses, 2020-current

Objective: The objective of this study was to evaluate the effects of refeeds and diet breaks on biochemical, body composition, and resting metabolic rate (RMR) measures during an energy-restricted diet.

Methods: Resistance-trained men between the ages of 18-45 participated in an 8-week IER weight loss diet plan. Participants were randomly assigned to one of two dietary intervention groups: Group 1 received two days/week of refeeds (REF), and Group 2 received a one-week diet break every two weeks (BRK). All participants followed a standardized volume weight training protocol. Baseline and post-intervention dual-energy X-ray absorptiometry (DXA) scans and blood measures were conducted …

The Effect Of Training Status On Exercise Performance And Oxygen Uptake Responses To Beetroot Juice Supplementation In Cyclists, Haley Mcvannel

Masters Theses, 2020-current

Purpose: To determine if cardiovascular fitness, assessed by peak oxygen consumption (VO_2peak),influences the physiological and performance effects of beetroot juice (BRJ) supplementation and to explore if recent training habits independently influence this response. Methods: Thirteen male and female cyclists completed two graded exercise tests to assess cardiovascular fitness and four, seven-day experimental phases. Five subjects were classified as high fitness (VO_2peak: 65.9 ± 4.5 mL∙kg^-1∙min^-1) and eight as lower fitness (VO_2peak: 44.2 ± 7.0 mL∙kg^-1∙min^-1). Subjects consumed 140 ml of concentrated BRJ or placebo the last …

Voluntary Alcohol Consumption And Sleep Deprivation In Rats, Aesha Khan

Masters Theses, 2020-current

Alcohol is one of the most common psychoactive drugs and has depressant effects on the central nervous system. The vast majority of research on alcohol and sleep commonly indicates chronic alcohol use has a detrimental impact on sleep architecture and homeostasis. However, less research has been conducted investigating the effects of sleep deprivation on alcohol consumption. Our lab's previous studies have looked at a potential bi-directional relationship between sleep and alcohol with promising results. However, there was concern that the method of sleep deprivation may have resulted in stress. The present study examines the effect of sleep deprivation on voluntary …

Therapeutic Potential Of A Ketogenic Diet In The Treatment Of Major Depressive Disorder, Jordan A. Murrin

Masters Theses, 2020-current

Major depressive disorder (MDD) is the second most common mental health condition and a leading cause of disability in the world. It is theorized that MDD develops from a combination of biological, psychological, and social stressors. The condition is typically treated using pharmaceuticals and psychotherapy. However, not all individuals with MDD have access to or choose to use these treatments, or may prefer to incorporate therapeutic lifestyle changes such as exercise, sleep, and healthy eating. Even with treatment, MDD can alter brain structure and function, leading to the development of comorbid mental health and chronic metabolic conditions like obesity, cardiovascular …

Effect Of Ambient Temperature On Recovery Of Surgically Instrumented Sprague-Dawley Rats, Gianna Mangone

Senior Honors Projects, 2020-current

Based on current guidelines for housing rodents after surgical instrumentation, rodents may be housed at temperatures that hinder surgical recovery and cause thermal stress– room temperature (21°C) being one of them. Rodents are often housed at room temperature since this temperature is easy for humans to be caring for them. However, if recovering rodents are thermally stressed, experimental results will be confounded. To address this issue, Sprague-Dawley rats were surgically instrumented with radiotelemtry thermoprobes (Data Sciences, #TA-10F40) to monitor their core temperatures, then housed at one of five temperatures to assess the effect ambient temperature had on multiple aspects of …

Hematological Changes In Response To A Drastic Increase In Training Volume In Recreational Cyclists, Jessie Axsom

James Madison Undergraduate Research Journal (JMURJ)

Changes in blood volume contribute to improvement in oxygen utilization (VO2max) with chronic endurance exercise training. Although hematological changes resulting from long-term endurance training have been well documented, it has not been well established whether an increased volume of endurance training preferentially affects plasma volume or red blood cell volume. To answer this question, I studied seven female and four male recreational cyclists before and after exposure to drastic increases (632%) in training volume. Following the 10-week training period, the mean hematocrit (Hct) of the 11 subjects who completed the study significantly (p0.05) correlated with the change in self-reported weekly …

The Combined Effects Of Soil Fertility And Soil Amendments On The Growth And Mycorrhizal Associations Of American Ginseng (Panax Quinquefolius), Emily Ann Murray

Masters Theses, 2010-2019

Arbuscular mycorrhizal fungi (AMF) are fungi that form symbiotic associations with 70-90% of plant families. They are known to allow for the extension of the root system as well as an increase in plant size by assisting with the uptake of nutrients such as nitrogen and phosphorus. The role that AMF play in plant health and success has led to the development of commercial inoculum, which is used in agricultural settings. However, soil fertility, and soil amendments are known to affect AMF and plant associations. This study intends to look at how cultivated American Ginseng seedlings are affected by commercial …

The Effect Of Ambient Temperature On Recovery Of Surgical Stress In Sprague-Dawley Rats, Romie D. Powell

Masters Theses, 2010-2019

Laboratory animals are housed at ambient temperatures ranging from 20°C – 26°C per recommended guidelines. Rats in particular typically prefer ambient temperatures (Tamb) of ~27°C (Brown et al, 2011). When rats undergo surgical instrumentation for experimental use, they often recover at normal room temperature (~21°C). While this is comfortable to those maintaining them, it may lead to a cold thermal stress for the rats. It is hypothesized that housing rats at ambient temperatures away from their preferred Tamb could lead to a thermal stress, which adversely affects surgical recovery. To address this, rats (220g-350g) were surgically instrumented with a radiotelemetry …

The Effect Of Depression On Bone Mineral Density In College-Aged Females, Caitlin A. Cadematori

Senior Honors Projects, 2010-2019

Research regarding the relationship between depression and bone mineral density (BMD) has produced very inconsistent and limited results, especially in younger females. The purpose of this study was to examine the relationship between depression scores and BMD in college-aged female students. Forty-six participants, ages 18-24 (+/-1.0368) completed a 24-hour dietary recall, medical history, Beck’s Depression Inventory and the Depression, Anxiety, and Stress Scale (DASS) and had their femur and sacral vertebrae BMD, z-score, and t-score measured in the Dual X-Ray Absorptiometry (DXA) machine. Participant demographics were analyzed with descriptive statistics and potential variable correlations were analyzed by partial and bipartial …

Discourses Of Madness And Me: Critical Examinations Of Western Discourses Of Madness And Psychiatry, Erin E. Casey

Showcase of Graduate Student Scholarship and Creative Activities

This paper is a critical examination of western medical paradigms alongside histories of psychiatry that argues for a culturally situated approach to mental health advocacy that maintains the importance of the physiological foundations of traditional biomedical approaches to disease. In doing so, I examine the discourses of madness, and society’s attempts to control and “fix” what is deemed “mad” through a historical lens. My position and critique utilizes a reflexive narrative process embracing my identities both as a consumer of mental health services and as an advocate for those with mental illnesses.

Characterization Of Vibrio Vulnificus Strains Using Phenotypic And Genotypic Assays, James Conrad

Masters Theses, 2010-2019

In this study 143 V. vulnificus isolates of clinical and environmental origin, were examined for growth on differential media, identified to species and tested for antibiotic resistance. A multiplex PCR was created and optimized, and phylogenetic analysis was conducted. The first objective was to compare phenotypic methods to identify V. vulnificus. Colony colors of confirmed V. vulnificus isolates on selective media (Vibrio vulnificus agar, thiosulfate citrate bilesalts sucrose agar, CHROMAgar Vibrio (CAV), and colistin polymyxin B cellobiose agar), mostly matched those characteristic of V. vulnificus. To test the ability of these media to select for V. vulnificus, new presumptive V. …

Cycling Time Trial Performance Is Not Enhanced By Either Whey Protein Or L-Alanine Intake During Prolonged Exercise, Adam B. Schroer

Masters Theses, 2010-2019

Previous studies have reported that adding protein (PRO) to a carbohydrate (CHO) solution can enhance endurance performance. This ergogenic effect may be a function of additional calories from supplemental protein/amino acids, but this thesis has not been directly examined. Additionally, L-alanine (ALA) is readily oxidized when provided during exercise; the impact that this has on metabolism and prolonged endurance performance is unknown. The purpose of this investigation was to assess performance and various cardiovascular and metabolic outcomes during prolonged cycling, to independently gauge the efficacy of whey PRO hydrolysate and ALA supplementation. Eight trained male and female cyclists (age: 22.3±2.0 …

Early Flute Pedagogy: The Utilization Of Alternative Types Of Flutes For Young Children, Erin Murphy

Dissertations, 2014-2019

The typical practice in flute pedagogy is to start teaching the beginning flute student at approximately ten years of age. When compared to many other instrument disciplines, such as violin and piano, this is a relatively late starting age. The delay is primarily due to the large size and weight of the modern orchestral flute, as well as its lung capacity requirements. Not only do the physical limitations of the modern flute make early study difficult, but if disregarded, they also may pose health risks for the young beginner. This paper will discuss the importance of early childhood musical study …

Using Encapsulated Fluorescent Bioprobes To Detect Explosive Materials In Soil, Clint Smith, Joel Tabb

The Journal of Conventional Weapons Destruction

This article examines the methods involved in using fluorescent bioprobes to detect explosive devices within soil. By genetically modifying plants through the injection of certain chemicals, visible responses indicate the presence and placement of explosive material, aiding demining agents in the process of mapping and removing various landmines or other explosive remnants of war. The adoption of these tools proves useful for stand-off detection of low TNT concentrations in the laboratory and controlled microcosm studies.

Job Satisfaction In Young Professional Athletic Trainers, Jennifer Stollery

Masters Theses, 2010-2019

Job satisfaction levels in young professional athletic trainers in multiple settings were examined quantitatively using the Job Satisfaction Survey (Spector, 1997) and qualitatively using an open-ended survey question. Job satisfaction levels were calculated to find that young professional athletic trainers are satisfied with their jobs according to the normative mean data for the scale. Post hoc analysis of the comparison of satisfaction levels by setting suggests that college/university athletic trainers have significantly lower job satisfaction levels than secondary school and clinic/outreach athletic trainers. Qualitative data suggests a high negative response rate revealing pay and operating procedures as two of the …

Activation Of Gabaa And 5ht1a Receptors In The Raphe Pallidus Abolish The Cardiovascular Responses To Stress In Conscious Rats, Nhut Minh Pham Le

Masters Theses, 2010-2019

Serotonergic neurons of the raphe pallidus area of the brainstem are involved in the cardiovascular responses to stress. However, the manner in which they mediate these responses is not well understood and severe abnormalities in this system have been associated with Sudden Infant Death Syndrome. In the current study, microinjections of muscimol and 8-OH-DPAT (GABAA and 5HT1A receptor agonists, respectively) into the raphe pallidus abolished the increase in mean arterial pressure and the tachycardiac responses following air jet, handing, and restraint stress that were observed following microinjections of artificial cerebrospinal fluid. The stress responses following muscimol microinjections suggest that this …

Medical Support To Demining In Sudan, Russell Wyper

The Journal of Conventional Weapons Destruction

With an area of more than one million square miles (2,589,988 square kilometers), Sudan is the largest country on the African continent and has been at the center of decades of conflict since it gained its independence in 1959. The Comprehensive Peace Agreement signed in January 2005 brought to end a vicious civil war and marked the beginning of an era of relative peace. This article outlines the health challenges involved in mine action in Sudan and highlights the actions taken by the United Nations Mine Action Office in Sudan to address issues of medical support to humanitarian-demining operations in …

Countering The Global Landmine Epidemic Through Basic Scientific Research, Mark S. Rountree, Robert M. Harris

The Journal of Conventional Weapons Destruction

Since their first use during the U.S. Civil War (Croll 1998), blast landmines have played a role in almost every armed conflict from the World Wars to the most recent limited skirmishes. Landmines are the epitome of the consummate soldier: always ready, never tiring. Mines are simple devices that can be fabricated with little effort and from readily available materials. In Sri Lanka, numerous news releases covering the conflict mention a "Johnny mine" (Botsford 1997), which is a local term for an improvised explosive device. Manufactured mines can be inexpensive, costing as little as two dollars apiece. If mine laying …
