Novel Effects Of Prefoldin Pathway On Intestinal Homeostasis Via Dietary Restriction In Drosophila Melanogaster, Jesse Simons

Dissertations, Masters Theses, Capstones, and Culminating Projects

The field of medicine research is embroiled in a battle against aging. Particular focus is on the extension of lifespan and health-span. Lifespan duration is affected by many factors, one of which is the maintenance of the intestines of the organism. Homeostasis of the intestines is controlled by the regulation of intestine cell apoptosis and intestine cell proliferation. My research explores the role of two protein subunits found in a complex which may have possible functions in the regulation of these processes. The overall complex is formed from six subunit proteins, some of which are known to assist in other …

Beyond Capture: Development And Validation Of A Method To Assess Body Condition In Mule Deer (Odocoileus Hemionus) Using Camera Traps, Rachel A. Smiley 6820420

Honors Scholar Theses

Advances in technology and availability associated with camera traps have resulted in a rapid rise in their use to monitor wildlife distribution, abundance, and behavior. We focus on assessing body condition, a new application of camera traps. Body condition indices must relate to the percent body fat if they are to be useful. To acquire measurements of body fat, most body condition indices require capture or mortality of animals to estimate, which has limitations when applied to free-ranging animals. We developed a non-invasive, visual body condition index (VBCI) to assess body condition of mule deer that can be applied …

The Contribution Of Solid Food On Total Water Intake In 3-13 Y Children, Audrey Caroline Smith

Health, Human Performance and Recreation Undergraduate Honors Theses

Introduction: Adequate hydration is important element of good health. Several studies indicate that the majority of kids are hypohydrated and do not meet dietary water intake guidelines. Some scientist also suggest that good hydration might be achieved by large consumption of food that are rich in water (i.e. fruits and vegetables). However, the information of food consumption on total water intake in children is limited.

Purpose: We evaluated the contribution of water from solid food on total water intake in children.

Methodology: For this cross-sectional study 81 children (35 female) 3 to 13 years old were randomly recruited to participate. …

Department of Nutrition and Health Sciences: Faculty Publications

The pathogenesis of atopic dermatitis (AD) is complex and related to allergic responses and defects in skin barrier function. In common with many atopic diseases, the prevalence of AD has been increasing across the world.1 One of the theories for this increase is increased hygiene and urbanization-related changes in the environment, which can affect the human microbiome.2 Previous studies have found associations between the composition of the early gut microbiome and development of atopic conditions, including AD.3 Although the rate of atopic conditions, including AD and food allergy, is increasing on all continents, the prevalence of these diseases is still …

Efficacy Of A Mobile Application For Improving Gait Performance In Community-Dwelling Older Adults, Dustin Glenn Falls

Masters Theses & Specialist Projects

The United States is a rapidly aging nation. Older adults have higher rates of falls than any other age group. One in four older adults fall each year. Many of these falls are associated with sedentary lifestyles and decreased muscular strength effecting balance and gait performance. Physical activity (exercise) can reduce the risk of falls among older adults, yet adherence remains low. Exergames can increase adherence to interventions that promote health and physical activity. Social engagement can increase self-efficacy and motivation to exercise. By design, the Bingocize® health promotion mobile application (app) increases social engagement, while providing a multi-factorial fall …

Lactose Intolerance: An Overview Of The Facts And Their Implications, Noelle M. Yeo

Honors Program: Senior Projects (Public)

Lactose intolerance is often blamed for the symptoms such as bloating, diarrhea, gas, abdominal pain, and nausea, that ail many people. Patients often do not seek proper diagnosis from a physician and create their own treatment plans, severely restricting lactose intake, without professional guidance. Even those who do seek the care of a physician find that diagnosis is complicated by less-than ideal testing and confusion due to the symptoms common to many other conditions. The misconceptions and inability to confirm a diagnosis of lactose intolerance can cause nutrient deficiencies in these patients, as well as begin a pattern of unnecessary …

Barriers To Breastfeeding Among Rural Women In The United States, Kimberly Aschbrenner, Disa Lubker Cornish

UNIversitas: Journal of Research, Scholarship, and Creative Activity

Breastfeeding is well-established as a beneficial practice for both infants and mothers; substantial evidence from a wide variety of international settings supports the positive impacts of breastfeeding. However, a significant proportion of U.S. infants are not fed according to this standard. While poor breastfeeding rates can be found in all parts of the United States, the problem is particularly prevalent among mothers living in rural environments where health outcomes are consistently worse than national averages. Significant differences have been found between urban and rural women in many breastfeeding behavioral outcomes, including consistently lower rates reported among rural populations. The problem …

Parental Views Of Promoting Fruit And Vegetable Intake Among Overweight Preschoolers And School-Aged Children, Martha J. Nepper, Weiwen Chai

Department of Nutrition and Health Sciences: Faculty Publications

Given the importance of parental influence on children’s eating habits, we explored perceptions of parents of overweight (body mass index–for-age percentile ≥85%) preschoolers (3-5 years) and overweight school-aged children (6-12 years) regarding challenges in promoting fruit and vegetable intake and how they and other family members influence their overweight children’s dietary habits. Focus groups were conducted with 13 parents of overweight preschoolers and 14 parents of overweight school-aged children. Codes and themes were developed by inductive data analysis. Four common themes were identified: short shelf life of fresh fruits and vegetables prohibiting parents from purchasing, children’s taste changes in fruits …

Food Ingredients That Inhibit Cholesterol Absorption, Elliot D Jesch, Timothy P. Carr

Department of Nutrition and Health Sciences: Faculty Publications

Cholesterol is a vital component of the human body. It stabilizes cell membranes and is the precursor of bile acids, vitamin D and steroid hormones. However, cholesterol accumulation in the bloodstream (hypercholesterolemia) can cause atherosclerotic plaques within artery walls, leading to heart attacks and strokes. The efficiency of cholesterol absorption in the small intestine is of great interest because human and animal studies have linked cholesterol absorption with plasma concentration of total and low density lipoprotein cholesterol. Cholesterol absorption is highly regulated and influenced by particular compounds in the food supply. Therefore, it is desirable to learn more about natural …

A Performance Study Of Apis Mellifera With Dietary And Forage Restrictions During Spring Colony Establishment In Lyon County, Kentucky, Dominique Wood

Murray State Theses and Dissertations

One-third of our worldwide fruit, nut and vegetable production is completely dependent on the existence of pollinators. Commercial honey bees, Apis mellifera, have an annual economic value of $15 billion in the U.S. Additionally, their honey is valued at $150 million annually. In Fall 2006, commercial beekeepers observed sudden mass disappearances of whole colonies. By Spring 2007, the condition, dubbed Colony Collapse Disorder (CCD), raised environmental and fiscal concerns while the cause(s) continued to be sought. Forensic examinations of hive samples did not reveal a singular cause of CCD. The results pointed to a collection of detrimental factors affecting …

Characterizing Food Insecurity At A Northeast Land-Grant University, Alana Ruth Davidson

Honors Theses and Capstones

In 2015, 15.8 million U.S. households were food insecure. While nationally food insecurity is assessed at the household and childhood level, university students are not explicitly monitored. The purpose of this study was to determine the prevalence of food insecurity at a northeast land grant university and characterize the contributing factors. A pilot study (n=211) was conducted in fall 2014 among a general nutrition class and found that 12.4% of students were food insecure, with another 5.7% reported marginal food security. A larger, university wide survey among graduate and undergraduate students was conducted in fall 2015 (n=943) and found that …
