Starch-Entrapped Microsphere Fibers Improve Bowel Habit But Do Not Exhibit Prebiotic Capacity In Those With Unsatisfactory Bowel Habits: A Phase I, Randomized, Double-Blind, Controlled Human Trial, Heather E. Rasmussen, Bruce Hamaker, Kumar B. Rajan, Ece Mutlu, Stefan J. Green, Michael Brown, Amandeep Kaur, Ali Keshavarzian

Department of Nutrition and Health Sciences: Faculty Publications

Approximately one-third of individuals in the United States experience unsatisfactory bowel habits, and dietary intake, especially one low in fiber, could be partly responsible. We hypothesized that intake of a fermentable fiber (starch-entrapped microspheres, SM) that has a delayed, slow fermentation profile in vitro would improve bowel habit while exhibiting prebiotic capacity in those with self-described unsatisfactory bowel habits, all with minimal adverse effects. A total of 43 healthy volunteers completed a 3-month,double-blind, parallel-arm randomized clinical trial to assess the ability of a daily dose (9 or 12 g) of SM vs. psyllium (12 g) to improve bowel habit, including …

Fernandez, Ivan Jose Vechetti Jr, Paula P. Freire, Rodrigo W. A. Souza, Rolando A.R. Villacis, Silvia R. Rogatto, Patricia P. Reis, Maeli Dal-Pai-Silvia, Robson F. Carvalho

Department of Nutrition and Health Sciences: Faculty Publications

Cardiac cachexia (CC) is a common complication of heart failure (HF) associated with muscle wasting and poor patient prognosis. Although different mechanisms have been proposed to explain muscle wasting during CC, its pathogenesis is still not understood. Here, we described an integrative analysis between miRNA and mRNA expression profiles of muscle wasting during CC. Global gene expression profiling identified 1,281 genes and 19 miRNAs differentially expressed in muscle wasting during CC. Several of these deregulated genes are known or putative targets of the altered miRNAs, including miR-29a-3p, miR-29b-3p, miR-210-5p, miR-214, and miR-489. Gene ontology analysis on integrative mRNA/miRNA expression profiling …

The Effects Of Calorie Information Disclosures On Food Choice And Retailer-Related Outcomes, Christopher Berry

Graduate Theses and Dissertations

Federal legislation will begin requiring the provision of calorie information on the menus and menu boards of restaurants and other retail food establishments with 20 or more locations in May 2018. Food retailers not included in this mandate can choose to voluntarily provide calorie information to consumers. However, there are concerns that this major policy change will not have the desired widespread positive effects on consumer choice behavior. Further, although proponents of calorie labeling argue that consumers have the right to know the calorie content of their food orders, many food retailers have argued that calorie labeling is too expensive …

A Comparative Analysis Of The Nutrient Composition And Digestibility Of California Perennial And Annual Grasses At Four Stages Of Growth, Elaina Cromer

Master's Theses

Beef products represent the fourth largest agricultural commodity in the state of California, valuing more than $3 billion from 2013 to 2015 (CDFA, 2016) and procure 90% of the income for the range livestock industry (FRAP, 2003). Forages found on California’s coastal, desert, foothill, and mountain ranges are the basis of the state’s beef cattle industry. Understanding their nutritional quality of these forages is important for their effective use (George et al., 2001a; Waterman et al., 2014). The objectives of this research were to investigate the nutritional characteristics, and in situ digestbilities in Angus beef cattle, of common California annual …

Adaptive Thermogenesis And Metabolic Changes Following Diet- And Exercise-Induced Weight Loss, Alexandra R. Martin

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

With more than two-thirds of adults in the United States considered as overweight or obese, a myriad of weight loss programs and products that promise quick results have infiltrated the market. While many individuals successfully lose weight over the short term, almost half of the initial weight lost is regained within one year, indicating a general predisposition for weight cycling and fat replenishment. As weight is lost, fat-free mass (FFM) also decreases, and resting metabolic rate (RMR) declines, decreasing energy expenditure. After accounting for decreases in FFM, there remains a greater-than- predicted decrease in RMR, referred to as adaptive thermogenesis …

Effects Of Curcumin And Ursolic Acid On The Mitochondrial Coupling Efficiency And Hydrogen Peroxide Emission Of Intact Skeletal Myoblasts, Daniel J. Tueller

Theses and Dissertations

Curcumin is a natural compound that improves blood glucose management. While some evidence from isolated mitochondria indicates that curcumin uncouples electron transport from oxidative phosphorylation, the effects of curcumin on mitochondrial respiration and hydrogen peroxide emission in intact skeletal muscle cells are not known. By assessing rates of oxygen consumption, we demonstrated for the first time that curcumin (40 µM) reduced the mitochondrial coupling efficiency (percentage of oxygen consumption that supports ATP synthesis) of intact skeletal muscle cells. A 30-minute incubation with curcumin decreased mitochondrial coupling efficiency by 17.0 ± 0.4% relative to vehicle (p < 0.008). Curcumin also decreased the rate of hydrogen peroxide emission by 43 ± 13% compared to vehicle (p < 0.05). Analysis of cell respiration in the presence of curcumin revealed a 40 ± 4% increase in the rate of oxygen consumption upon curcumin administration (p < 0.05 compared to vehicle). In additional experiments, no difference in mitochondrial coupling efficiency was observed between vehicle- and curcumin-pretreated cells after permeabilization of cell membranes (p > 0.7). The possibility of synergistic …

Formulation, Characterisation And Stability Assessment Of A Food Derived 1 Tripeptide, Leucine-Lysine-Proline Loaded Chitosan Nanoparticles, Minna Khalid Danish, Giuliana Vozza, Hugh Byrne, Jesus Maria Frias, Sinead Ryan

Articles

The chicken or fish derived tripeptide, Leucine-Lysine-Proline (LKP), inhibits the Angiotensin Converting Enzyme and may be used as an alternative treatment for pre-hypertension. However, it has low permeation across the small intestine. The formulation of LKP into a nanoparticle (NP) has the potential to address this issue. LKP-loaded NPs were produced using an ionotropic gelation technique, using chitosan (CL113). Following optimisation of unloaded NPs, a mixture amount design was constructed using variable concentration of CL113 and tripolyphosphate at a fixed LKP concentration. Resultant particle sizes ranged from 120-271 nm, zeta potential values from 29-37 mV and polydispersity values from 0.3-0.6. …

Establishment Of Innovative Shared Departments To Advance Interdisciplinary Education, Ronald S. Harichandran, Brian Kench, Summer Mcgee, Michael A. Collura, Jean Nocito-Gobel, Charles David Skipton

Engineering and Applied Science Education Faculty Publications

More and more universities are pursuing interdisciplinary academic activities that span across department and college boundaries. Administrative structures to facilitate such programs are difficult to establish within traditional university frameworks consisting of disciplinary departments and colleges. Often interdisciplinary programs are housed in a traditional disciplinary department or college, or in a standalone center reporting to a college dean or the provost. The difficulty of these structures is obtaining broad buy-in from faculty across departments and having disciplinary degree programs include interdisciplinary coursework.

To overcome the difficulties described above, an innovative shared department structure that fosters collaborations to advance interdisciplinary education …

The Role Of Nr4a1 In Β-Cell Glucose Stimulated Insulin Secretion And Cellular Survival, Kevin Garland, Jeffery Tessem

Journal of Undergraduate Research

In 2010, diabetes was the 7th leading cause of death in America, and as of 2014, 9% of the world’s adult population was affected by it. In both Type I (T1D) and Type II diabetes (T2D), a loss of β-cell mass and overall function is observed. β-cells essentially stop proliferating after adolescence, therefore developing mechanisms to increase function and/or induce proliferation in β-cells could serve as a powerful treatment and even a cure for both T1D and T2D. Overexpression of the β-cell transcription factor Nkx6.1 induces β-cell proliferation (1) and up-regulates expression of the nuclear receptor Nr4a1 (2). Nr4a1 has …

What Motivates Young Adults To Talk About Physical Activity On Social Network Sites?, Ni Zhang, Shelly Campo, Jingzhen Yang, Petya Eckler, Linda Snetselaar, Kathleen Janz, Emily Leary

Faculty Research, Scholarly, and Creative Activity

Background:
Electronic word-of-mouth on social network sites has been used successfully in marketing. In social marketing, electronic word-of-mouth about products as health behaviors has the potential to be more effective and reach more young adults than health education through traditional mass media. However, little is known about what motivates people to actively initiate electronic word-of-mouth about health behaviors on their personal pages or profiles on social network sites, thus potentially reaching all their contacts on those sites.
Objective:
This study filled the gap by applying a marketing theoretical model to explore the factors associated with electronic word-of-mouth on social network …

Relationships Between Nutrition-Related Knowledge, Self-Efficacy, And Behavior For Fifth Grade Students Attending Title I And Non-Title I Schools, Elisha M. Hall, Weiwen Chai, Julie A. Albrecht

Department of Nutrition and Health Sciences: Faculty Publications

The Social Cognitive Theory (SCT) is a widely used theory for nutrition education programming. Better understanding the relationships between knowledge, self-efficacy, and behavior among children of various income levels can help to form and improve nutrition programs, particularly for socioeconomically disadvantaged youth. The purpose of this study was to determine the relationships between knowledge, self-efficacy, and behavior among fifth grade students attending Title I (≥ 40% of students receiving free or reduced school meals) and non-Title I schools (< 40% of students receiving free or reduced school meals). A validated survey was completed by 55 fifth grade students from Title I and 122 from non-Title I schools. Differences in knowledge, self-efficacy, and behavior scores between groups were assessed using t test and adjusted for variations between participating schools. Regression analysis was used to determine the relationships between knowledge, self-efficacy, and behavior. In adjusted models, the Title I group had significantly lower scores on several knowledge items and summary knowledge (P = 0.04). The Title I group had significantly lower scores on several behavior variables including intakes of fruits (P = 0.02), vegetables (P = 0.0005), whole grains (P = 0.0003), and lean protein (P = 0.047), physical activity (P = 0.002) and summary behavior (P = 0.001). However the Title I group scored higher on self-efficacy for meal planning (P = 0.04) and choosing healthy snacks (P = 0.036). Both self-efficacy (β = 0.70, P < 0.0001) and knowledge (β = 0.35, P = 0.002) strongly predicted behavior; however, only self-efficacy remained significant in the Title I group (self-efficacy, β = 0.82, P = 0.0003; knowledge, β = 0.11, P = 0.59). Results demonstrate disparities in nutrition knowledge and behavior outcomes between students surveyed from Title I and non-Title I schools, suggesting more resources may be necessary for lower income populations. Findings suggest that future nutrition interventions should focus on facilitating the improvement of children's self-efficacy

Cebp/Α Increases Functional Β-Cell Mass, Jason Ray, Jeffery Tessem

Journal of Undergraduate Research

Type 1 and Type 2 diabetes are major global health concerns. Diabetes is characterized by impaired management of glucose in the bloodstream, which is due to decreased pancreatic functional β-cell mass. Functional β-cell mass is determined from the insulin secretion rate and the number of β-cells, which is determined from cellular proliferation and death rates. Increasing functional β-cell mass could cure diabetes either by enhancing pancreatic islets prior to transplantation, or by strengthening endogenous cells. Although β-cells stop proliferating around adolescence, β-cell proliferation resumes during conditions such as pregnancy and obesity (1), demonstrating that the molecular pathways necessary for replication …
