Holocarboxylase Synthetase-Dependent Biotinylation Of Histone H4, Luisa F. Rios Avila

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

Holocarboxylase synthetase (HCS) catalyzes the binding of biotin to lysine (K) residues in histones H3 and H4. Histone biotinylation marks play important roles in the repression of genes and retrotransposons. Preliminary studies suggested that K16 in histone H4 is a target for biotinylation by HCS. Here we demonstrated that H4K16bio is overrepresented in repeat regions {pericentromeric alpha satellite repeats; long terminal repeats (LTR)} compared with euchromatin promoters. H4K16bio was also enriched in the repressed interleukin-2 gene promoter. The enrichment at LTR22 and promoter 1 of the sodium-dependent multivitamin transporter (SMVT) depended on biotin supply; and was significantly lower in fibroblasts …

Micronutrient Deficiencies As A Result Of Bariatric Surgery, Ashlie Lewis

Food Science and Nutrition

The most effective method of sustainable weight loss in obese patients is bariatric surgery. However, micronutrient deficiencies that can result after bariatric surgery can cause health problems that may outweigh its benefits. Micronutrient deficiencies are most common in patients who undergo Roux-en-Y gastric bypass or biliopancreatic diversion with or without duodenal switch. The majority of vitamin B12 and folate deficiencies studies showed significant prevalence rates in their patient populations. Most concluded that routine oral B12 supplementation was ineffective at resolving deficiency; very high oral doses (> 350 μg) or intramuscular injections of crystalline B12 were typically required. Studies of iron …

Validation Of Nutrition Standardized Language—Next Steps, Paula Ritter-Gooder, Nancy M. Lewis

Department of Nutrition and Health Sciences: Faculty Publications

To provide a model for quality care and outcomes management, the Nutrition Care Process (NCP) and standardized language were introduced in 2003 by the American Dietetic Association (ADA). The standardized language, published in the International Dietetics & Nutrition Terminology (IDNT) Reference Manual: Standardized Language for the Nutrition Care Process, is designed to facilitate communication, improve care, and close the gap in health care quality. When registered dietitians (RDs) are oriented to a nutrition care process, improvement in their documentation of nutrition care occurs. Since the introduction of the NCP and standardized language, RDs and dietetic technicians, registered (DTRs), have …

Weight Discrimination: Why Current Perceptions Need To Change, Kelsey Rae Eller

Undergraduate Honors Capstone Projects

Discrimination based on weight has been labeled the last form of socially acceptable prejudice. Weight discrimination is becoming more and more prevalent in schools, the workplace, social settings, the media, and even in healthcare. Overweight and obese individuals are often stereotyped as lazy, addicted to food, and lacking self-discipline and initiative, and as a result may struggle with decreased employment opportunities, fear and shame in public, attempting dangerous weight loss methods, or even eating disorders.

This project seeks to identify and examine research that has been done on this subject in order to increase awareness of weight bias and to …

An Investigation Of Dietary Supplementation As A Potential Source Of Nutrition Misinformation Hindering The Development Of Healthy Eating Habits In The College Population, Mary Dimmick

Undergraduate Honors Capstone Projects

Current dietary supplement legislation allows nutrition misinformation to flourish; misleading structure‐function and health‐claims now abound on supplement labels. Meanwhile, college students tend to be open to experimentation and exploration. Hence, this study’s objective was to discover if students at USU are being influenced by such claims to unjustifiably take dietary supplements in a manner which hinders the development of healthy eating habits. During August of 2009, 1,300 USU freshmen were invited to voluntarily participate in an on‐line survey concerning dietary patterns which included a section about dietary supplementation. Five‐hundred‐and‐twelve completed the survey after providing informed written consent to participate. The …

Significant Interactions With The Most Commonly Used Herbal And Nonherbal Supplements Impact Warfarin Safety And Efficacy, Brittany Jean Sagers

Undergraduate Honors Capstone Projects

Background: Nearly 20% of adult Americans used herbal therapies in 2007, but greater than two-thirds failed to report such use to their medical provider. Significant patient harm may occur when herbal supplements are taken in conjunction with warfarin; however, patients and medical providers may not be aware of these interactions and this may place patients at risk for life-threatening bleeds or thrombotic complications.

Methods: The authors determined the top 25 herbal and 25 nonherbal supplements used by Americans using sales data from 2008, and each product was reviewed for its potential to interact with warfarin. Electronic searches were conducted using …

To What Extent Do Local Farmers' Markets, Community Supported Agriculture Programs, And Community Gardens Help Low-Income Families Improve Access To Fresh, Local Produce?, Christy Gene Somsen

Undergraduate Honors Capstone Projects

Farmers’ Markets, Community Supported Agriculture (CSA) Programs, and Community Gardens have been developed to help farmers. Many times, they also aim to help low-income families improve access to fresh produce. Often, these programs may end up helping a larger amount of middle class families instead of lower class families. There have been many programs developed to try to better help low-income families such as the Women Infant and Children (WIC) Farmers’ Market Nutrition Program (FMNP) and allowing farmers to accept WIC Cash Value Vouchers (CVV), which allows WIC participants to buy fresh produce. Farm to School Programs have also been …

Role Of Protein Kinase C Isotypes In 1,25-Dihydroxyvitamin D3 Mediated Signal Transduction Through The 1,25d3 Membrane Associated, Rapid Response Steroid Binding Receptors In Chick Intestinal Cells, Sakara Tunsophon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is now accepted that 1,25(OH)2D3 mediates its rapid actions on the control of phosphate and calcium homeostasis through its membrane receptor termed the 1,25D3-MARRS (membrane associated rapid response steroid binding) protein. I determined the various PKC isotypes involved in the rapid regulation of phosphate uptake and calcium extrusion in chick intestinal cells. 1,25(OH)2D3-mediated phosphate uptake was stimulated within 1 min after addition of the hormone. Western blot analyses on isolated intestinal cells treated with steroid hormone resulted in dose-dependent increases in PKC alpha and PKC beta in postnuclear centrifugation fractions, but not in the low speed centrifugation fractions. The …

Unsaturated Fatty Acids Repress The Expression Of Adipose Fatty Acid-Binding Protein, Ap2, In Raw 264.7 Macrophage, Sara L. Coleman

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

Adipocyte fatty acid binding protein, aP2, present in macrophages has been implicated in the integration of lipid metabolism and inflammatory response, contributing to development of insulin resistance and atherosclerosis. We investigated the modulation of aP2 expression by inflammatory insults and fatty acids in RAW 264.7 macrophages. When the cells were incubated with lipopolysaccharides (LPS; 100 ng/ml) or 10 ng/ml of tumor necrosis factor α for 18 h, aP2 mRNA and protein levels were drastically increased. Unsaturated fatty acids (100 μM of 18:1, 18:2, 18:3, 20:5 in complex with BSA), but not saturated fatty acids (16:0), significantly repressed the basal aP2 …

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

Naturally occurring compounds and lifestyle modifications as combination and mono-therapy are increasingly used for dyslipidemia. Specficially, phytosterols and fatty acids have demonstrated an ability to modulate cholesterol and triglyceride metabolism in different fashions. In two separate studies, the lipid-lowering effects of black raspberry seed oil and three different phytosterol stearates were examined in order to elucidate the effects of these dietary components and the factors influencing their therapeutic actions.

The first study examined high cholesterol diets supplemented with crude and refined black raspberry seed oils, coconut oil or soybean oil. The crude and refined raspberry seed oil (RSO) treatments significantly …

The Effect Of A Motivational Intervention On Weight Loss Is Moderated By Level Of Baseline Controlled Motivation, Kelly H. Webber, Jeanne M. Gabriele, Deborah F. Tate, Mark B. Dignan

Dietetics and Human Nutrition Faculty Publications

BACKGROUND: Clinic-based behavioral weight loss programs are effective in producing significant weight loss. A one-size-fits-all approach is often taken with these programs. It may be beneficial to tailor programs based on participants' baseline characteristics. Type and level of motivation may be an important factor to consider. Previous research has found that, in general, higher levels of controlled motivation are detrimental to behavior change while higher levels of autonomous motivation improve the likelihood of behavior modification.

METHODS: This study assessed the outcomes of two internet behavioral weight loss interventions and assessed the effect of baseline motivation levels on program success. Eighty …

Sorghum: An Ancient, Healthy And Nutritious Old World Cereal, United Sorghum Checkoff Program, John Lindsay
