The Effects Of Selected Drugs On The Memory Recall Of Sleep Deprived Mice, Jenn Pauldurai

Capstone Research Projects

Humans often make use of the neurotransmission altering effects of drugs such as caffeine, ephedrine, and ethanol. These drugs induce changes in memory and learning ability, specifically when used for sleep deprivation. English white mice (Mus musculus) have been shown to exhibit similar cognitive changes when administered drugs while sleep deprived. A sample of 20 mice was divided into three experimental groups (each group receiving a different drug) and one control group. Maze-testing demonstrated that mice performance decreased with sleep deprivation (Treatment-1) but all groups returned to baseline performance when injected (IP) with selected drugs (Treatment-2), regardless of …

Feasibility Of Farm-To-School In Alaska: A State-Wide Investigation Of Perspectives From School Food Service Professionals, Johanna Ruth Herron

Other

Childhood obesity is a significant public health concern and schools are a key setting for prevention. The majority of U.S. children are enrolled in school where they consume a large portion of their daily energy. Farm-to-school programs are a promising strategy for preventing childhood obesity in school-aged children. The overall objective of this study was to conduct a baseline assessment of Alaska school food service professionals' perspectives of using local foods. Specific objectives were to: 1) Assess interest in utilizing local foods, 2) Identify perceived barriers to purchasing local foods, and 3) Determine resources needed to facilitate local food procurement. …

Long-Term Benefits Of Early Intervention Services: A Meta-Synthesis, Elizabeth Barnes

Special Education Masters Program Theses

The role of universal preschool programs is being debated in public and political arenas. There is concern that the cost of providing such programs is not in the public's best interest. While they are few, the longitudinal studies into the cost/benefit of such programs show that investments into early childhood interventions and education yield a return to students, taxpayers, and society. These benefits include: a savings in the cost of education through lower retention rates and special education placement, an increase in tax revenue through higher wages, and a savings through lower costs for the welfare and criminal justice systems. …

Cancer Control Continuum Gap Analysis: Inventory Of Current Policy And Environmental Strategies, Rosyland Frazier, Mouhcine Guettabi, Katie Cueva

ISER Reports

"Comprehensive cancer control (CCC) is a process through which communities and partner organizations pool resources to reduce the burden of cancer. These combined efforts help to reduce cancer risk, find cancers earlier, improve treatments, and increase the number of people who survive cancer. ”This analysis has explored both current policies that have been enacted in Alaska at the state and federal level, and those that are acknowledged at a national level. The gap analysis is designed to inform the State DHSS as it takes steps to develop a policy agenda for comprehensive cancer control that aims to; reduce the risk …

Investigations Of Substrate Channeling In The Proline Oxidative Pathway, Nikhilesh Sanyal

Department of Biochemistry: Dissertations, Theses, and Student Research

In cell metabolism, substrate channeling is a phenomenon where the product of one reaction is transported to a second enzyme active site without equilibrating into bulk solvent. Chapter 1 reviews the rationale and evidence for substrate channeling with the specific example of proline metabolism. Oxidation of proline to glutamate is catalyzed in consecutive reactions by proline dehydrogenase (PRODH) and pyrroline-5-carboxylate dehydrogenase (P5CDH). The intermediate Δ¹-pyrroline-5-carboxylate reportedly tends to be labile and inhibitory towards several metabolic pathways.

One of the main objectives of this dissertation was to investigate substrate channeling between independent proline oxidative enzymes from Thermus thermophilus- …

Developing Stable Isotope Biomarkers Of Yup'ik Traditional And Market Foods To Detect Associations With Chronic Disease Risk, Sarah H. Nash

Biological Sciences

This dissertation addresses the need for valid measures of dietary intake for use in studies of chronic disease risk in the Yup'ik population of Southwest Alaska. The Yup'ik people have experienced dietary changes over the past century, as consumption of traditional foods has been increasingly supplemented or replaced by market-purchased foods. Determining whether this dietary change is associated with increases in chronic disease risk is important for making nutritional recommendations for disease prevention. However, monitoring dietary change is challenging, in part due to the limitations of self-reported methods of dietary assessment. Dietary biomarkers are promising alternatives to self-reported methods, because …

Physical Activity, Body Composition And Their Associations With Health In Yup'ik People, Maria D. Bray

Biological Sciences

Being active and preventing excess body fat are important for maintaining good health. The ability to measure activity and body composition accurately is important to understanding the role of activity and adiposity in health. This dissertation highlights key findings regarding assessment tools for physical activity and body composition and the associations between physical activity and body composition with health in Yup'ik people. The main objectives of this dissertation were to: l) assess the accuracy of bioimpedance and multiple regression models from anthropometry for estimating body composition (fat mass, fat-free mass, and percent body fat) as compared with doubly-labeled water (DLW) …

The Role Of High-Fat Feeding On The Up-Regulation In Antioxidant Enzymes: A Potential, Innocence Christianna Harvey

Electronic Theses and Dissertations Archive

While RONS are produced as part of normal metabolism, excess production can occur in response to stressors, such as physical exercise and ingestion of excess nutrients (e.g., saturated fat). Over time this may lead to an up-regulation in antioxidant enzyme activity, in an attempt to protect cells. The purpose of this investigation was to determine if an increase in antioxidant enzyme activity is observed following repeatedingestion of high fat meals. Sixteen healthy men consumed10 high fat milkshakes over a 3+ weekperiod. Blood was taken from subjects on the firstday of each week (before andfor 4 hours after milkshake ingestion) and …

The Impact Of Classroom Activity Breaks On The School-Day Physical Activity Of Rural Children, Teresa Bershwinger, Timothy A. Brusseau

International Journal of Exercise Science

International Journal of Exercise Science 6(2) : 134-143, 2013. Schools have been identified as a central element in a system that ensures that children participate in enough physical activity to develop healthy lifestyles. Even with this recommendation, many school-based physical activity opportunities are being eliminated/minimized (i.e. physical education (PE), recess). With children spending much of their time at school, other supplemental physical activity opportunities are essential. One such opportunity is through classroom teacher led activity breaks. Very little evidence exists identifying the impact of classroom activity breaks on the daily physical activity patterns of children. Therefore, the purpose of this …

Effects Of Exercise Sequence In Resistance-Training On Strength, Speed, And Agility In High School Football Players, Shawn Johnson, Steve Burns, Kari Azevedo

International Journal of Exercise Science

International Journal of Exercise Science 6(2) : 126-133, 2013. Manipulating variables in a training program (e.g., sets, reps, lifts, sequence, etc.) is designed to maximize strength and power performance. Due to the complexity of designing resistance-training programs, changing one variable could potentially set an athletic team apart from others in performance. The purpose of this study was to investigate if exercise sequence could influence the development of strength, speed, and agility. This study compared two specific types of exercise sequences: traditional, which performs the prescribed exercises in a traditional or blocked manner (by completing every set of an exercise before …

Effects Of Foot Position During Squatting On The Quadriceps Femoris: An Electromyographic Study, Nicholas G. Murray, Daniel Cipriani, Denise O'Rand, Rebecca Reed-Jones

International Journal of Exercise Science

International Journal of Exercise Science 6(2) : 114-125, 2013. Weightlifters have commonly believed that changing joint position can alter specific muscle activation. The magnitude of force produced by a muscle is highly dependent upon the length of the muscle. The purpose of this study was to determine the effect of foot positioning on muscle activation of the superficial quadriceps as measured by surface electromyography (sEMG) during a functional squatting movement in healthy adults. Twenty physically active asymptomatic adults (7 females and 13 males) were included in the study while four different foot positions (Neutral, Internally Rotated, Externally Rotated, and Staggered) …

Acute Ingestion Of L-Arginine Alpha-Ketoglutarate Fails To Improve Muscular Strength And Endurance In Rotc Cadets, Benjamin Wax, Jerry J. Mayo, Laura A. Hilton, Harris C. Mareio, Justin D. Miller, Heather E. Webb, Brian Lyons

International Journal of Exercise Science

International Journal of Exercise Science 6(2) : 91-97, 2013. L-Arginine Alpha-Ketoglutarate (AAKG) is purported to stimulate the release of nitric oxide, and is suggested to facilitate muscular performance by increasing blood flow and increase oxygen and nutrient delivery to the working muscle. However, the ergogenic benefit of AAKG during resistance exercise has not been established. Therefore the purpose of this study was to investigate the effects of acute AAKG ingestion in active ROTC Cadets on measures of one-repetition maximal strength (1RM) and muscular endurance. Nineteen apparently healthy males ingested either AAKG (3 g) or a placebo 45 minutes prior to …

Interdisciplinary Research Scholarship Day

The purpose of this study was to retrospectively calculate the head injury criteria (HIC) values for pediatric patient falls and correlate these values to documented injury severity (MERP) scores. A second purpose was to examine the relationship between child ages and associated HIC15 values in an attempt to scale the values obtained from pediatrics to adult values.

Gender Differences In Frontal Plane Lower Extremity Kinetic Variability During Landing, Andrew Nordin

Interdisciplinary Research Scholarship Day

Investigations of human movement variability have been used as a
means of exploring neuromotor functioning, where performance variability is
thought to provide the system with flexibility and a mechanism for adaptation to
movement repetition [1,2,4,6]. Operationally, variability has been considered to
fall within optimal limits (Figure 1), while excessively high or low variability has
been implicated in injury susceptibility [1,2,4,6]. Landing has been explored
due to a high incidence of injury in athletic performance, as well as the ability
to easily control task demands through increases in landing height [3,4].
The purpose of this investigation was to evaluate changes in …

Interactive Video Gaming: Do We Feel Like We Are Exercising?, Antonio Santo, Shaelee Allen, Janet Dufek, Paul Hafen, Michael Jarrett, Krystina Moschella, Robert Rietjens, James Navalta, Richard Tandy, Jacob E. Barkley

Interdisciplinary Research Scholarship Day

The primary purpose of this study was to determine if the rating of perceived exertion (RPE) and hedonics (liking or enjoyment) changed during 30 contiguous minutes of playing select, interactive video games on the Nintendo Wii system. A secondary purpose was to determine if RPE and liking differed among games.These data suggest that individuals do perceive difference in the amount of work they are performing during extended play of the same game or among sedentary and physically interactive games. Additionally, liking was similar during extended game play and among games suggesting that the physical interaction with the game may be …

Examining Lower Extremity Range Of Motion And Movement Variability Chages Due To Focus Of Attention During Landing, Andrew Nordin, Janet Dufek

Interdisciplinary Research Scholarship Day

Attentional focus (AF) has been explored among a variety of motor skills providing evidence that external AF promotes automaticity and enhanced performance [6]. External focus of attention is distinguished from internal focus such that external focus is directed toward movement effect rather than body movements [6]. Movement variability provides a means of assessing functional characteristics of the neuromotor system, where normal functioning is suggested to occur within optimal limits, while excessively high or low movement variability is indicative of system dysfunction [2,4,5]. Additionally, the ability of the motor system to vary, or broadly distribute, internal loads is thought to reduce …
