Department of Nutrition and Health Sciences: Faculty Publications

Background: Interleukin (IL)-27 is a heterodimeric cytokine belonging to IL-12 and IL-23 families, secreted by antigen presenting cells(APCs). The IL-27 is composed of 2 subunits: Epstein-Barr virus induced gene 3 (EBI3) and p28. IL-27 is an anti-inflammatory cytokine which has an inhibitory effect on Th17 population and suppress the IL-17 expression. It is suggested that IL-27 could be a potent drug candidate for treating auto immune diseases.

Materials and Methods: The EBI3 and p28 subunits of human interleukin 27 were constructed into plasmid vectors; they sub-cloned into pETDuet-1 expression vector in restriction sites of BamHI, SacI and NotI. Subsequently the …

Impact Of Whole Grain Consumption Compliance On Gluten Sensitivity And Bowel Health, Sarah Anne Roberts

Walden Dissertations and Doctoral Studies

While many health benefits have been associated with increased whole grain consumption, current researchers have not considered if the consumption of whole grains in currently recommended or higher amounts actually leads to health problems, specifically to a correlated increase in gluten sensitivity. The purpose of this study was to determine if diets high in whole grains or those that met the recommended daily intake of whole grains help minimize or increase gluten sensitivity, and when whole grains are consumed as recommended if they cause more harm than good. The theoretical basis for this quantitative, cross sectional design was the precaution …

NutritionQuest Data-on-Demand System was used to analyze nutrients and food group intake. The postpositivist paradigm was used to examine how the independent and dependent variables relate to each other. Using a one-sample t test, a comparison of …

Bmp7 Drives Human Adipogenic Stem Cells Into Metabolically Active Beige Adipocytes, Meshail Okla, Jung-Heun Ha, Ryan E. Temel, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

Adult humans have a substantial amount of inducible-brown (or beige) fat, which is associated with increased energy expenditure and reduced weight gain via thermogenesis. Despite the identification of key regulators of beige adipogenesis, impacts of dietary factors on adaptive thermogenesis are largely unknown, partly due to a lack of validated human cell models. Bone morphogenetic protein 7 (BMP7) is known to promote brown adipogenesis in rodent and human progenitor cells. However, controversy still surrounds the cellular identity in BMP7-mediated transition of white to brown adipocytes. The aim of this study is to confirm BMP7-derived human adipocytes as a relevant in …

Fruit And Vegetable Perceptions Among Caregivers Of American Indian Toddlers And Community Stakeholders: A Qualitative Study, Rachel C. Sinley, Julie A. Albrecht

Department of Nutrition and Health Sciences: Faculty Publications

This disparity begins to develop in early childhood, and the excess weight carried by American Indian children contributes to health conditions that can affect their quality of life by the time they enter preschool. These children consume less than recommended amounts of fruits and vegetables, a dietary pattern that may be related to the development of obesity and other health conditions. This qualitative study explored the fruit and vegetable intake of American Indian toddlers through use of the information-motivation-behavioral skills (IMB) model. Focus groups …

Uric Acid Level Is Associated With Postprandial Lipemic Response To A High Saturated Fat Meal, Roy Gail Cutler

Walden Dissertations and Doctoral Studies

Hyperlipidemia caused by a diet high in saturated fat can lead to visceral fat weight gain, obesity, and metabolic syndrome. Being over-weight from visceral fat has been linked to increased risk of developing most age-related diseases and disability, along with a lower income potential and quality of life. However, researchers are just beginning to understand the biological mechanisms that regulate the conversion of excess calories into visceral fat storage rather than glycogen or muscle. Epidemiological studies have repeatedly shown a comorbid association between age-related diseases involving hyperlipemia and circulating levels of uric acid, but not a direct association. This study …
