Sugar Price Supports And Taxation: A Public Health Policy Paradox, Abby Dilk, Dennis Savaiano

Student Works

Domestic US sugar production has been protected by government policy for the past 82 years, resulting in elevated domestic prices and an estimated annual (2013) $1.4 billion dollar “tax” on consumers. These elevated prices and the simultaneous federal support for domestic corn production have ensured a strong market for high-fructose corn syrup. Americans have dramatically increased their consumption of caloric sweeteners during the same period. Consumption of “empty” calories (ie, foods with low-nutrient/high-caloric density)—sugar and high-fructose corn syrup being the primary sources—is considered by most public health experts to be a key contributing factor to the rise in obesity. There …

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 …

Jones, Constance D. Brindley, David W. Threadgill, Jens J. Holst, Bolette Hartmann, Terrence A. Barrett, Daniel H. Teitelbaum, Peter J. Dempsey

Internal Medicine Faculty Publications

BACKGROUND & AIMS: Total parenteral nutrition (TPN), a crucial treatment for patients who cannot receive enteral nutrition, is associated with mucosal atrophy, barrier dysfunction, and infectious complications. Glucagon-like peptide-2 (GLP-2) and epidermal growth factor (EGF) improve intestinal epithelial cell (IEC) responses and attenuate mucosal atrophy in several TPN models. However, it remains unclear whether these 2 factors use distinct or overlapping signaling pathways to improve IEC responses. We investigated the interaction of GLP-2 and EGF signaling in a mouse TPN model and in patients deprived of enteral nutrition.

METHODS: Adult C57BL/6J, IEC-Egfr^{knock out (KO)} and IEC-pik3r1^KO mice receiving …

A Step Towards A "Greener" Dining Services: Procuring Locally For The Health Of Students And The Earth, Jessica Fischer

Senior Honors Projects

Supporting local food has been a goal of dining services for some time now. Buying local means you know exactly where your food is coming from. Typically the farmer has a direct relationship with the processors that puts pressure on them to abide by all laws and regulations. Secondly, the shorter time between the farm and your table, the less likely that nutrients will be lost during the time it takes to transport food across the country. Third, buying local food builds a sense of community. When you buy direct from a farmer, you’re engaging in a time-honored connection between …

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. …

Anti-Cancer And Bioavailability Of Arachidin-1 And Arachidin-3 In Colon Cancer Cells, Macy R. Shirley

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 …

Handgrip Strength In Children With Cystic Fibrosis, Hannah Taylor Gibson

Theses and Dissertations

Background: Body mass index (BMI) is the primary accepted method to determine nutrition status in children with cystic fibrosis (CF); however, lean body mass (LBM) is more strongly associated with pulmonary function. Handgrip strength (HGS) measures muscle function and is reflective of LBM. The aims of this study were to assess if there was a relationship among HGS, nutrition status, and pulmonary function, to assess if HGS changed after hospitalization, and to assess if there was a relationship between HGS and nutrient intake.
