Metabolic Characterization Of A Sirt5 Deficient Mouse Model, Jiujiu Yu, Sushabhan Sadhukhan, Lilia G. Noriega, Norman Moullan, Bin He, Robert S. Weiss, Hening Lin, Kristina Schoonjans, Johan Auwerx

Department of Nutrition and Health Sciences: Faculty Publications

Sirt5, localized in the mitochondria, is a member of sirtuin family of NAD1-dependent deacetylases. Sirt5 was shown to deacetylate and activate carbamoyl phosphate synthase 1. Most recently, Sirt5 was reported to be the predominant protein desuccinylase and demalonylase in the mitochondria because the ablation of Sirt5 enhanced the global succinylation and malonylation of mitochondrial proteins, including many metabolic enzymes. In order to determine the physiological role of Sirt5 in metabolic homeostasis, we generated a germline Sirt5 deficient (Sirt52/2) mouse model and performed a thorough metabolic characterization of this mouse line. Although a global protein hypersuccinylation and elevated serum ammonia during …

Exercise Participation During Weight Loss On A High Protein – Low Carbohydrate Diet Plan In Females Aged 15-25 Years, Margaret Mobley-Meulman

Electronic Theses and Dissertations

Weight gain due to poor diet and lack of exercise is responsible for over 300,000 deaths each year (U.S. Department of Health and Human Services, 2010). Obese adults have an increased risk for serious health conditions including high blood pressure and cholesterol, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems, and certain cancers (National Cancer Institute, 2012). Participation in exercise can help control weight, strengthen muscles and bones, and reduce the incidence of cardiac events, stroke, hypertension, type 2 diabetes, colon and breast cancers, osteoporotic fractures, gallbladder disease, obesity, depression, anxiety, and delay mortality …

The Obesity Epidemic, Lenka Kollar, Evienne Epifano, Molly Mckneight, Jeff Miskovich, Heather Moore

Student Papers in Public Policy

The incidence of chronic, noncommunicable diseases, such as heart disease, is increasing at an alarming rate on the global scale. The growing prevalence of overweight and obesity have led to an upsurge in cases of diabetes and other obesity-related diseases. About 18 million people die every year from heart disease, of which diabetes and obesity are major predisposing factors. Worldwide, more than 1.1 billion adults are overweight, 312 million of which are obese. The number of children that are overweight or obese is also growing (Hossain, Parvez et al.). Obesity, and the associated diseases, has become a worldwide epidemic and …

Associations Between Alcohol Consumption And Fasting Blood Glucose In Young Adults, Julie Ann Lucca

Master's Theses

Current research shows moderate alcohol consumption is associated with decreased risk of diabetes and excessive consumption or binge drinking can cause insulin resistance and diabetes. In 2010, diabetes was the seventh leading cause of death in the United Statesand was responsible for significant health complications: blindness, kidney failure, and limb amputations, and is a large national economic burden. Fasting blood glucose (FBG) is a tool used to help diagnose diabetes. Abnormally high FBG, ≥100 mg/dl, is indicative of diabetes and pre-diabetes. Few studies have observed diabetic prevalence among young adults or college students. Studying young adults can help provide added …

A Literature Review Of The Health Effects Of A Plant Based Diet Versus An Animal Based Diet, James Cote

Senior Honors Theses

Health and nutrition can mean a myriad of things to many people in today’s culture. The majority of the time people are unaware of the proper nutrients their body needs and how to get them from food. This thesis will seek to expose the health benefits that are associated with consuming a raw plant-based die, offering a more profound and encompassing view on nutrition. Investigating further into today’s most common diseases such as diabetes, heart disease, obesity, cancer and autoimmune disorders, it will seek to discover and answer why we have so many health issues. This thesis will discuss the …

Acceleration Of The Panin Development In Mice Expressing Oncogenic K-Ras Due To A High Fat Diet, Bincy Philip

Dissertations and Theses (Open Access)

Obesity is postulated to be one of the major risk factors for pancreatic cancer, and recently it was indicated that an elevated body mass index (BMI correlates strongly with a decrease in patient survival. Despite the evident relationship, the molecular mechanisms involved are unclear. Oncogenic mutation of K-Ras is found early and is universal in pancreatic cancer. Extensive evidence indicates oncogenic K-Ras is not entirely active and it requires a triggering event to surpass the activity of Ras beyond the threshold necessary for a Ras-inflammation feed-forward loop. We hypothesize that high fat intake induces a persistent low level inflammatory response …

School Gardens: Reconnecting Children With Nature And Food, Alyssa M. Boyle

Scripps Senior Theses

This thesis discusses the importance of school gardens. First, two current environmental and societal problems are highlighted: the industrialized food system and what Richard Louv has termed, "Nature Deficit Disorder," in children. School gardens are then presented as an effective tool that can address and remedy such issues. Lastly, a how-to manual for implementing such projects in schools is provided as well as a few sample lesson plans to be used in conjunction with the garden in each subject across the curriculum.

Comparison Of Recycling Outcomes In Three Types Of Recycling Collection Units, Ashley Andrews, Mary Gregoire, Heather Rasmussen, Gretchen Witowich

Department of Nutrition and Health Sciences: Faculty Publications

Commercial institutions have many factors to consider when implementing an effective recycling program. This study examined the effectiveness of three different types of recycling bins on recycling accuracy by determining the percent weight of recyclable material placed in the recycling bins, comparing the percent weight of recyclable material by type of container used, and examining whether a change in signage increased recycling accuracy. Data were collected over 6 weeks totaling 30 days from 3 different recycling bin types at a Midwest university medical center. Five bin locations for each bin type were used. Bags from these bins were collected, sorted …

Effects Of Forage Species Or Concentrate Finishing On Animal Performance, Carcass And Meat Quality, S. K. Duckett, J. P.S. Neel, Ronald M. Lewis, J. P. Fontenot, W M. Clapham

Department of Animal Science: Faculty Publications

Angus-cross steers (n = 128; initial BW = 270 ± 3.8 kg) were used in a 3-yr study to assess effects of forage species grazed before slaughter versus concentrate finishing on carcass and meat quality. At the completion of the stockering phase, steers were randomly allotted to mixed pasture (MP; n = 36/yr) or corn-silage concentrate (CON; n = 12/yr) finishing treatments. At 40 d before harvest, MP steers were randomly divided into 3 forage species treatments: alfalfa (AL), pearl millet (PM), or mixed pasture (MP). Average daily BW gain was greater (P = 0.001) for CON than …

Vitamin B12 Deficiency In Relation To Functional Disabilities, Breanna S. Oberlin, Christy C. Tangney, Kristin A. R. Gustashaw, Heather E. Rasmussen

Department of Nutrition and Health Sciences: Faculty Publications

This study was designed to assess whether symptoms, functional measures, and reported disabilities were associated with vitamin B12 (B12) deficiency when defined in three ways. Participants, aged 60 or more years of age, in 1999–2002 National Health and Nutrition Examination Surveys (NHANES) were categorized in relation to three previously used definitions of B12 deficiency: (1) serum B12 < 148 pmol/L; (2) serum B12 < 200 pmol/L and serum homocysteine > 20 μmol/L; and (3) serum B12 < 258 pmol/L or serum methylmalonic acid > 0.21 μmol/L. Functional measures of peripheral neuropathy, balance, cognitive function, gait speed, along with self-reported disability (including activities of daily living) were examined with standardized instruments by trained NHANES interviewers and technicians. Individuals identified as B12 deficient …

Food Webs And Food Sovereignty: Research Agenda For Sustainability, Charles A. Francis, Michelle Miller, Molly Anderson, Nancy Creamer, Michelle Wander, Jacob Park, Thomas Green, Brent Mccown

Department of Agronomy and Horticulture: Faculty Publications

Future food production will be constrained by the scarcity of fossil fuel and fresh water as well as increasing intensity and unpredictability of weather events and climate changes. The assurance of food security and equity for many consumers is complicated by concentration of ownership of land and other production resources, as well as a global corporate food systems model that is driven by profit at the expense of people and the environment. To assess potential alternatives to the contemporary global food chain, well focused research is needed on local food production and food webs where small- and midscale family farms …

The purpose of this study, therefore, was to examine the effects of ANA supplementation on the recovery of isometric strength and selected non-invasive indicators of muscle damage.

Methods: A double-blinded, placebo-controlled, crossover design was used to study eighteen men (mean ± SD age = 22.2 ± 3.1 yrs; body mass = 80.3 ± 15.7 kg) who participated in two randomly-ordered conditions separated by a washout period. The ANA condition consisted …

Identification And Assessment Of Markers Of Biotin Status In Healthy Adults, Wei Kay Eng, David Giraud, Vicki L. Schlegel, Dong Wang, Bo Hyun Lee, Janos Zempleni

Department of Nutrition and Health Sciences: Faculty Publications

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 sixteen healthy men and women. A total of 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 biotin-deficient and biotin-sufficient individuals. The urinary excretion …

Polyphenols, Inflammation, And Cardiovascular Disease, Christy Tangney, Heather E. Rasmussen

Department of Nutrition and Health Sciences: Faculty Publications

Polyphenols are compounds found in foods such as tea, coffee, cocoa, olive oil, and red wine and have been studied to determine if their intake may modify cardiovascular disease (CVD) risk. Historically, biologic actions of polyphenols have been attributed to antioxidant activities, but recent evidence suggests that immunomodulatory and vasodilatory properties of polyphenols may also contribute to CVD risk reduction. These properties will be discussed, and recent epidemiological evidence and intervention trials will be reviewed. Further identification of polyphenols in foods and accurate assessment of exposures through measurement of biomarkers (i.e., polyphenol metabolites) could provide the needed impetus to examine …

Oxidative stress is involved in age-related cognitive decline. The dietary antioxidants, carotenoids, tocopherols, and vitamin A may play a role in the prevention or delay in cognitive decline. In this study, sera were obtained from 78 octogenarians and 220 centenarians from the Georgia Centenarian Study. Brain tissues were obtained from 47 centenarian decedents. Samples were analyzed for carotenoids, 𝛼-tocopherol, and retinol using HPLC. Analyte concentrations were compared with cognitive tests designed to evaluate global cognition, dementia, depression and cognitive domains (memory, processing speed, attention, and executive functioning). Serum lutein, zeaxanthin, and 𝛽-carotene concentrations were most consistently related to better cognition …

All Current Publications

Disaster has many faces: earthquake, fire, hurricane, tornado, severe thunderstorm, winter storm, financial uncertainty, and more. Disasters can disrupt the normal services we come to expect and sometimes take for granted. Examples are electricity, food, and water. FEMA, the Federal Emergency Management Agency, advocates disaster preparedness. They advise people to be informed, make a plan, and prepare an emergency kit. A major part of that emergency kit is food and water for you and your family. But, what types of food should you store? How much food should you store? How will you cook it?  Does it need to be …
