School Food Environment The Frontline For Childhood Obesity Prevention: A Mixed-Method Study Of Nutritional Competencies And Skills Of School Nutriiton Professionals In Nebraska, Zainab Rida

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

The purpose of this statewide study was to address the nutrition knowledge, attitudes, and perceptions of school foodservice personnel in Nebraska regarding offering/serving healthy school meals. Moreover, this study identified some potential barriers and avenues of action for offering/serving healthy school meals. Data obtained from this study indicates that there is a strong correlation (r= .103, p r .237, p< .01) between the foodservice staff’s self-efficacy and their practices of offering/serving healthy school meals. Fortunately, the relationship between foodservice staff practices of offering/serving healthy school meals and their self-efficacy was positive and significantly predicted practices scores, β =.237, P< 0.01. The finding of the present study also identifies many barriers including lack of time and support that face the foodservice personnel in offering/serving healthy school meals. The findings suggested that there is an urgent need of a full school approach to promote and encourage healthy eating habits among students. Future research is needed to evaluate school wellness policies regarding healthy eating practices in schools. Moreover, establish partnerships with communities and universities for intervention that target students and their parents.

Gut Microbiome Composition Is Linked To Whole Grain-Induced Immunological Improvements, Ines Martinez, James M. Lattimer, Kelcie L. Hubach, Jennifer A. Case, Junyi Yang, Casey G. Weber, Julie A. Louk, Devin J. Rose, Gayaneh Kyureghian, Daniel A. Peterson, Mark D. Haub, Jens Walter

Food for Health: Publications

The involvement of the gut microbiota in metabolic disorders, and the ability of whole grains to affect both host metabolism and gut microbial ecology, suggest that some benefits of whole grains are mediated through their effects on the gut microbiome. Nutritional studies that assess the effect of whole grains on both the gut microbiome and human physiology are needed. We conducted a randomized cross-over trial with four-week treatments in which 28 healthy humans consumed a daily dose of 60 g of whole-grain barley (WGB), brown rice (BR), or an equal mixture of the two (BR+WGB), and characterized their impact on …

A Pilot Study: The Use Of A Survey To Assess The Food Knowledge Of Nutrition Students At Various Levels Of Nutrition Education, Chante Chambers

College of Education and Human Sciences: Dissertations, Theses, and Student Research

A working definition of a concept known as ‘food literacy’ encompasses using basic food preparation knowledge that has been learned, understood, and practiced to make better food decisions. To advance these skills for client service, a post-secondary nutrition program would need to include objectives that allow application of knowledge. For this reason, the purpose of this study was to determine the difference in knowledge and application among students in 100, 200 and 400 level college nutrition course(s). A survey was developed to measure the food knowledge of these college students as they prepare for careers as health care professionals. The …

Impact Of The Home Food Environment On Dietary Intake, Obesity And Cardiovascular Health Of U.S. Children And Adolescents, Aged 6-19, Melissa A. Masters

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Youth obesity is an ongoing problem in the United States. Obese children and adolescents are likely to be obese as adults and have an increased risk of developing chronic diseases, including coronary heart disease, earlier in life. The multifactorial nature of obesity continues to challenge researchers and health professionals to determine methods for preventing and reducing childhood obesity. Research has suggested that obesity is a normal response to an “obesigenic” environment. Emerging as one of the most influential environments in obesity and behavior development is the home food environment. However, little is understood about the role of the home food …

Identification And Assessment Of Markers Of Biotin Status In Healthy Adults, Wei Kay Eng

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Human biotin requirements are unknown and the identification of reliable markers of biotin status is necessary to fill this knowledge gap. Here we used an outpatient feeding protocol to create states of biotin deficiency, sufficiency, and supplementation in 16 healthy men and women. Twenty possible markers of biotin status were assessed including the abundance of biotinylated carboxylases in lymphocytes, the expression of genes from biotin metabolism, and the urinary excretion of biotin and organic acids. Only the abundance of biotinylated 3-methylcrotonyl-CoA carboxylase (holo-MCC) and propionyl-CoA carboxylase (holo-PCC) allowed for distinguishing among all three levels of biotin intake. The urinary excretion …

Mixed Methods Analysis Of School Wellness Programs In Nebraska And Indiana: A Descriptive Study, Jessica A. Robinson

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Schools have become one of the major fronts that the battle against childhood obesity is being fought. In 2004 the Child Nutrition Act passed by Congress required all school districts receiving funds for the National School Lunch Program to create a wellness policy. Since then there have been many research projects conducted to learn more about these policies, and their implementation as programs in the schools. Thus far, no such research has been done in Nebraska or Indiana. The purpose of this descriptive study is to describe how schools in Nebraska and Indiana are implementing wellness programs in their schools. …

Single-Chain Vαvβ T Cell Receptors Function Without Mispairing With Endogenous Tcr Chains1, David H. Aggen, Adam S. Chervin, Thomas M. Schmitt, Boris Engels, Jennifer D. Stone, Sarah A. Richman, Kurt H. Piepenbrink, Brian M. Baker, Philip D. Greenberg, Hans Schreiber, David M. Kranz

Food for Health: Publications

Transduction of exogenous T cell receptor (TCR) genes into patients’ activated peripheral blood T cells is a potent strategy to generate large numbers of specific T cells for adoptive therapy of cancer and viral diseases. However, the remarkable clinical promise of this powerful approach is still being overshadowed by a serious potential consequence: mispairing of the exogenous TCR chains with endogenous TCR chains. These “mixed” heterodimers can generate new specificities that result in graft-versus-host reactions. Engineering TCR constant regions of the exogenous chains with a cysteine promotes proper pairing and reduces the mispairing, but, as we show here, does not …

A Pilot Study On The Attitudes Of Management Practices In Adults With Pku, Elizabeth L. Vlock

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Phenylketonuria (PKU) is a genetic disorder caused by the deficiency of the enzyme, phenylalanine hydroxylase. Phenylalanine accumulation in brain causes cognitive impairment and behavioral problems, which can be prevented by dietary restriction of phenylalanine. People with PKU have to maintain a highly restrictive low protein diet throughout their entire life. PKU is typically diagnosed at birth through newborn screening. In order for a patient to reach their optimal IQ and health status, they need to maintain their blood phenylalanine (phe) level within the recommended range of 60-360 µmol/L.

The purpose of this study is to investigate attitudes of adults diagnosed …

Conformational Melding Permits A Conserved Binding Geometry In Tcr Recognition Of Foreign And Self Molecular Mimics, Oleg Y. Borbulevych, Kurt H. Piepenbrink, Brian M. Baker

Food for Health: Publications

Molecular mimicry between foreign and self antigens is a mechanism of T cell receptor cross reactivity and is thought to contribute to the development of autoimmunity. The αβ TCR A6 recognizes the foreign antigen Tax from the virus HTLV-1 when presented by the class I MHC HLA-A2. In a possible link with the autoimmune disease HAM/TSP, A6 also recognizes a self peptide from the neuronal protein HuD in the context of HLA-A2. We found here that the complexes of the HuD and Tax epitopes with HLA-A2 are close but imperfect structural mimics, and that in contrast with other recent structures …

Food and Drug Administration Papers

Phenotypic and genotypic diversity of forty-two Pasteurella multocida isolates from geese were characterized by analysis of their capsular type, Heddleston serotype, biotype, fimbrial gene allele type, comparative outer membrane protein (OMP) electrophoresis patterns, and were analyzed using PCR for the presence of virulence-associated genes (toxA, tbpA, pfhA, hgbA, hgbB, nanH, nanB, fimA, hsf-1, and pmHAS). A sequence comparison of the thdF and rpoB housekeeping genes of twenty representative P. multocida strains from three different OMP groups demonstrated that seventeen strains were closely related phylogenetically to previously published strains of P. multocida subsp. multocida and P. multocida subsp. gallicida, and only …

Evolution Of Starvation Resistance In Drosophila Melanogaster: Measurement Of Direct And Correlated Responses To Artificial Selection, Tiffany E. Schwasinger-Schmidt, Stephen D. Kachman, Lawrence G. Harshman

Lawrence G. Harshman Publications

Laboratory selection for resistance to starvation has been conducted under relatively controlled conditions to investigate direct and correlated responses to artificial selection. With regard to starvation resistance, there are three physiological routes by which the trait can evolve: resource accumulation, energy conservation and starvation tolerance. A majority of energetic compounds and macromolecules including triglycerides, trehalose and other sugars, and soluble protein increased in abundance as a result of selection. Movement was additionally investigated with selected males moving less than control males and selected females exhibiting a similar response to selection. Results obtained from this study supported two of the possible …
