Department of Nutrition and Health Sciences: Faculty Publications

The purpose of this study was to compare the composite, inter-individual, and intra-individual differences in the patterns of responses for electromyographic (EMG) and mechanomyographic (MMG) amplitude (AMP) and mean power frequency (MPF) during fatiguing, maximal, bilateral, and isokinetic leg extension muscle actions. Thirteen recreationally active men (age = 21.7 2.6 years; body mass = 79.8 11.5 kg; height = 174.2 12.7 cm) performed maximal, bilateral leg extensions at 1801 until the torque values dropped to 50% of peak torque for two consecutive repetitions. The EMG and MMG signals from the vastus lateralis (VL) muscles of both limbs were recorded. Four …

Gut Microbiome: Profound Implications For Diet And Disease, Ronald D. Hills Jr., Benjamin A. Pontefract, Hillary R. Mishcon, Cody A. Black, Steven C. Sutton, Cory R. Theberge

Pharmaceutical Sciences Faculty Publications

The gut microbiome plays an important role in human health and influences the development of chronic diseases ranging from metabolic disease to gastrointestinal disorders and colorectal cancer. Of increasing prevalence in Western societies, these conditions carry a high burden of care. Dietary patterns and environmental factors have a profound effect on shaping gut microbiota in real time. Diverse populations of intestinal bacteria mediate their beneficial effects through the fermentation of dietary fiber to produce short-chain fatty acids, endogenous signals with important roles in lipid homeostasis and reducing inflammation. Recent progress shows that an individual’s starting microbial profile is a key …

The Impact Of Framing On Acceptance Of Cultured Meat, Christopher Bryant, Courtney Dillard

University Studies Faculty Publications and Presentations

Cultured meat can be produced from growing animal cells in-vitro rather than as part of a living animal. This technology has the potential to address several of the major ethical, environmental, and public health concerns associated with conventional meat production. However, research has highlighted some consumer uncertainty regarding the concept. Although several studies have examined the media coverage of this new food technology, research linking different frames to differences in consumer attitudes is lacking. In an experimental study, we expose U.S. adults (n = 480) to one of three different frames on cultured meat: “societal benefits,” “high tech,” and “same …

Development, Validation, And Testing Of The Eating And Food Literacy Behaviors Questionnaire With Young Adult University Students, Kwadernica Rhea

LSU Doctoral Dissertations

The Eating and Food Literacy Behaviors Questionnaire (EFLBQ) was developed, and its validity, reliability, and ability to measure construct changes was established. Items related to the originally proposed domains of food literacy were included in the initial questionnaire, however five, new components were discovered. The second version of the EFLBQ was tested with 257 young adult university students using exploratory factor analysis, and a five-factor model (R²=57.4%) was returned. Cronbach’s alpha coefficients were calculated (health and nutrition=0.89, taste=0.72, food preparation=0.77, planning /decision-making=0.64, and convenience=0.63). A confirmatory factor analysis, with 923 new responses provided evidence of an adequate fit …

The Role Of Nr4a1 In Β-Cell Growth And Onset Of Type 2 Diabetes, Adam Wynn, Jeffery Tessem, Ph.D.

Journal of Undergraduate Research

Progression to type 2 diabetes (T2D) includes a loss of functional pancreatic beta cells (β-cells), which are responsible for secreting insulin and maintaining healthy blood sugar levels. Nr4a1 is a gene that has been shown to be involved in fuel utilization in the liver, muscles, and adipose tissues,1, 2, 3, 4 but not much is known about its role in the β-cell and T2D progression. We therefore set out to further define Nr4a1’s role in the β- cell during T2D progression. We hypothesized that the loss of Nr4a1 in the pancreata of mice would result in decreased β-cell maintenance and …

All Student-Created Educational Resources

The infographic displays the timeline pertaining to the regulation created by the Food and Drug Administration to keep food manufacturers accountable for what is labeled on the food they produce. The evolution of nutrition labeling was not solely driven on the decisions made by the government, but also the interests of consumers. The process began in 1969 and has been evolving until present day. As scientists began to uncover the link between diet and food, consumers began to take note. The publishing of both The Surgeon General’s Report on Nutrition and Health and the National Research Council’s report and the …

The Effects Of Hyperlipidemia On Β-Cells, Andrew Barlow, Trevor Lloyd, Mason Poffenbarger, Austin Ricks, Dr. Jeffery Tessem

Journal of Undergraduate Research

Diabetes’ prevalence is increasing at an alarming rate. Normally, insulin-secreting β-cells in the pancreas regulate proper glucose absorption and storage. Type 1 and Type 2 diabetes are characterized by decreased functional β-cell mass and insulin production (1). Diabetes also results in increased circulating glucose and fatty acid levels, which damage and destroy β-cells over time (2). Our study sheds further light on the palmitate and oleate-induced effects of gradually worsening hyperlipidemia and the mechanisms behind those effects; ultimately, promoting investigation into methods by which existing β-cells could be protected from harmful hyperlipidemia.

Nf Κb As A Mediator In Iron Regulation, Erik D. Marchant, Chad Hancock

Journal of Undergraduate Research

Doxorubicin (DOX) is a commonly used chemotherapy drug. Although it is very effective in treating many different types of cancer, it has also been shown to induce oxidative stress in multiple tissues, partially due to severe iron-dysregulation. The effects of DOX have mostly been studied in heart tissue, because DOX has been shown to increase the risk of cardiomyopathy and other heart diseases. Besides causing damage to the heart, DOX has also been shown to contribute to muscle wasting. For this purpose, we decided to investigate how DOX causes iron-dysregulation in C2C12 myotubes, which are immortalized cells from mouse skeletal …

Potential Of Prebiotic Butyrogenic Fibers In Parkinson’S Disease, Thaisa M. Cantu-Jungles, Heather Rasmussen, Bruce R. Hamaker

Department of Nutrition and Health Sciences: Faculty Publications

Parkinson’s Disease (PD) is a neurodegenerative disorder characterized by loss of dopaminergic neurons in the substantia nigra. Recent evidence supports the involvement of the gastrointestinal tract in PD pathogenesis, including alterations in microbiota and intestinal permeability. Apart from being the preferred energy source for colonic epithelial cells, butyrate is involved in anti-inflammatory, enteroendocrine and epigenetic mechanisms that influence colonic and systemic health, including brain function. A few studies using oral administration of sodium butyrate indicate beneficial effects in PD animal models; however, prebiotic fibers that generate butyrate locally in the gut may be more effective. The design and selection of …

Iron Dysregulation Induced By Oxidative Stress Is Prevented By Curcumin In C2c12 Skeletal Muscle Cells, Jacob Anderson, Dr. Chad Hancock

Journal of Undergraduate Research

Recent studies indicate a correlation between iron dysregulation and insulin sensitivity, suggesting that iron dysregulation may play a role in the development of type 2 diabetes mellitus [1]. However, the connection between iron regulation and insulin sensitivity is not fully understood. Iron is normally tightly regulated, and most iron within cells is bound to prevent aberrant production of free radicals. Non-bound iron is highly reactive via Fenton Reaction chemistry to produce hydroxyl radicals, contributing to oxidative stress and possibly to the development of insulin resistance. Not only does mismanagement of iron contribute to oxidative stress, but evidence suggests that oxidative …

Associations Between Comorbid Tdp-43, Lewy Body Pathology And Neuropsychiatric Symptoms In Alzheimer's Disease, Ece Bayram, Guogen Shan, Jeffrey L. Cummings

School of Public Health Faculty Research

More than half of the patients with Alzheimer’s disease (AD) have comorbidities including TDP-43 and Lewy bodies, which are also associated with frontotemporal lobar degeneration and dementia with Lewy bodies, respectively. These comorbidities may help explain the overlapping neuropsychiatric symptoms between AD and other dementias. Data on 221 AD patients with Neuropsychiatric Inventory-Questionnaire were obtained from the National Alzheimer’s Coordinating Center. TDP-43 was associated with aberrant motor activity, whereas Lewy bodies were associated with anxiety, irritability, sleep behavior, and appetite problems. The associations between these comorbidities and neuropsychiatric symptoms were more significant for patients with sparse diffuse plaques.

Caloric Restriction Alters Postprandial Responses Of Essential Brain Metabolites In Young Adult Mice, Lucille M. Yanckello, Lyndsay E. A. Young, Jared D. Hoffman, Robert P. Mohney, Mignon A. Keaton, Erin L. Abner, Ai-Ling Lin

Sanders-Brown Center on Aging Faculty Publications

Caloric restriction (CR) has been shown to extend longevity and protect brain function in aging. However, the effects of CR in young adult mice remain largely unexplored. In addition to the fundamental, long-term changes, recent studies demonstrate that CR has a significant impact on transient, postprandial metabolic flexibility and turnover compared to control groups. The goal of this study was to identify the brain metabolic changes at a transient (2 h) and steady (6 h) postprandial state in young mice (5–6 months of age) fed with CR or ad libitum (AL; free eating). Using metabolomics profiling, we show that CR …

Meat Analogs From Different Protein Sources: A Comparison Of Their Sustainability And Nutritional Content, Ujué Fresán, Maximino Alfredo Mejia, Winston J. Craig, Karen Jaceldo-Siegl, Joan Sabaté

Faculty Publications

© 2018 by the authors. Meat analogs are processed foods designed to mimic meat products. Their popularity is increasing among people seeking foods that are healthy and sustainable. Animal-sourced protein products differ in both their environmental impact and nutritional composition. The protein sources to produce meat analogs come from different plants. There is a lack of published research data assessing differences in these two aspects of meat analogs according to the plant protein source. This study compared the greenhouse gas (GHG) emissions of different types of meat analogs according to their main source of protein (wheat, soy, wheat and soy, …
