Relationship Of Winter Hair Coat Shedding Ability Of Purebred Angus Dams With Mineral Status, Apparent Forage Digestibility, Uterine Artery Hemodynamics, And Calf Growth And Development, Randy Hunter Burnett

Theses and Dissertations

Winter hair coat shedding ability in southern U.S. cattle production has previously been associated with differences in adjusted birth and weaning weights of calves from dams that shed by June or later (Gray et al., 2011; Cauble et al., 2019). This study was developed to research possible avenues of why these relationships exist with winter hair coat shedding ability. The primary objectives of the following experiments were to: 1) evaluate how mineral status relates to winter hair coat shedding ability, 2) evaluate how winter hair coat shedding ability relates to apparent digestibility of forage, 3) evaluate winter hair coat shedding …

The Effects Of Various Carbon Sources And The Presence Of Vitamin B-12 On The Production Of 1,3-Propanediol By L. Reuteri., Kayden Stevenson

Fall Student Research Symposium 2021

Dairy product preservation has evolved over thousands of years and has been a major benefit to humanity by creating stable, nutrient-dense food sources. Today the lactic acid bacteria Lactobacillus reuteri is important in preserving fermented dairy products through the production of the compound reuterin. Reuterin (1,3-propanediol) demonstrates antibiotic properties that prevent the fermentation of dairy products by undesirable bacteria. The purpose of this study is to determine if L. reuteri can produce 1,3-propanediol from a variety of carbon sources. Bacterial strains were incubated in the presence of a carbon source with vitamin B-12 or without B-12 for seven days with …

Determination Of Free Fatty Acid And Triglyceride Fatty Acid Of Food Fats Using A Rapid Gas Chromatographic Method, Aubreyona Migliori

Fall Student Research Symposium 2021

Food fats are primarily triglycerides composed of esterified fatty acids on a glycerol backbone. To measure the fatty acid content of foods, a derivatization reaction is conducted which transfers the fatty acids from glycerol to methanol, forming a fatty acid methyl ester (FAME). FAMES are measured using gas chromatography with flame ionization detection (GC-FID). Free fatty acids in foods are a result of a degradation reactions and are considered a defect. This decreases consumer acceptance and expedites further deterioration which decreases the value of edible oils. The goal of this study was to develop a rapid and sensitive method to …

Dietetics and Human Nutrition Faculty Publications

Rural communities are disproportionally affected by food insecurity, making them vulnerable to the consequences of supply disruptions caused by the COVID-19 pandemic. While access to food was initially diminished due to food supply disruptions, little is known about the mechanisms through which federal emergency assistance programs impacted food access in rural populations. Through a series of five focus groups in spring 2021, we examined the impact of the COVID-19 pandemic on food access in a rural Appalachian community in Kentucky. Data were analyzed using a Grounded Theory Approach. Findings revealed the following four primary themes: food scarcity in grocery stores; …

Mechanical Overload-Induced Muscle-Derived Extracellular Vesicles Promote Adipose Tissue Lipolysis, Ivan J. Vechetti Jr, Bailey D. Peck, Yuan Wen, R Grace Walton, Taylor R. Valentino, Alexander P. Alimov, Cory M. Dungan, Douglas W. Van Pelt, Ferdinand Von Walden, Bjorn Alkner, Charlotte A. Peterson, John J. Mccarthy

Department of Nutrition and Health Sciences: Faculty Publications

How regular physical activity is able to improve health remains poorly understood. The release of factors from skeletal muscle following exercise has been proposed as a possible mechanism mediating such systemic benefits. We describe a mechanism wherein skeletal muscle, in response to a hypertrophic stimulus induced by mechanical overload (MOV), released extracellular vesicles (EVs) containing muscle-specific miR-1 that were preferentially taken up by epidydimal white adipose tissue (eWAT). In eWAT, miR-1 promoted adrenergic signaling and lipolysis by targeting Tfap2α, a known repressor of Adrβ3 expression. Inhibiting EV release prevented the MOV-induced increase in eWAT miR-1 abundance and expression of …

Probiotic Intervention Improves Recovery Of Hippocampal Memory And Hippocampal Atrophy Following Disruption From High-Fat Diet In Adult Rats, Sanyourah A. El-Hulu

Honors Scholars Collaborative Projects

Presently, lifestyle factors such as chronic high-fat diet (HFD) consumption occurs concomitantly with weight gain and obesity (Gil-Cardoso et al., 2017; Stranahan et al., 2008). In turn, obesity has been associated with impairments to mental functioning, specifically to memory. Human epidemiological studies show that HFD intake containing saturated, and omega-6-fatty acids is associated with worse performance on a cognitive task whereas a lower fat diet containing omega-3-fatty acids is associated with a protective effect against cognitive decline (Zhang et al., 2006; Uranga et al., 2010). One explanation for this is the critical role of the gut bacteria in brain health. …

Acute Consumption Of A Sugar-Sweetened Beverage Impairs Microvascular Function In Midwestern Hispanic Males, Emma Hirshman, Anne R. Crecelius

Health and Sport Science Faculty Publications

Hispanic males are at risk for cardiovascular disease and consume high levels of sugar-sweetened beverages (SSB); yet, their acute vascular response to SSBs is unknown. Ten healthy Hispanic men (18-45 years old) consumed a SSB and reactive hyperemia was performed prior to, immediately following, and 1-hr post-consumption. Both peak and total (area under the curve) forearm blood flow were attenuated immediately following consumption but returned to at or above pre-consumption levels at the 1-hr test.

Discerning The True Dilemma Of Diabetes Among Hispanics, Ramon Ponce

Nursing | Senior Theses

There is a common misconception that the primary role of nurses is to follow doctors’ orders and treat patients who are currently suffering and experiencing pain. Chronic illnesses such as diabetes can be prevented and better managed if the population who is greatest at risk is better informed and educated on the disease. Different cultures and ethnicities have different foods that unfortunately puts them at risk to get diabetes. Hispanics typically follow a diet that is high in carbohydrates, saturated fats, and sugars that greatly contribute to the development of diabetes. Often, Hispanics are not educated enough to comprehend the …

Breastfeeding Media Coverage And Beliefs During The Covid-19 Pandemic In Mexico: Implications For Breastfeeding Equity, Mireya Vilar-Compte, P. Gaitán‐Rossi, E. C. Rhodes, V. Cruz‐Villalba, R. Pérez‐Escamilla

Department of Public Health Scholarship and Creative Works

Background: Because breastfeeding offers short- and long- term health benefits to mothers and children, breastfeeding promotion and support is a public health priority. Evidence shows that SARS-CoV-2 is not likely to be transmitted via breastmilk. Moreover, antibodies against SARS-CoV-2 are thought to be contained in breastmilk of mothers with history of COVID-19 infection or vaccination. WHO recommends direct breastfeeding as the preferred infant feeding option during the COVID-19 pandemic, even among women with COVID-19; but conflicting practices have been adopted, which could widen existing inequities in breastfeeding. This study aims to describe how information about breastfeeding was communicated in Mexican …

Divergent Selection For Water Conversion Ratio In Broiler Populations, Joseph Hiltz

Graduate Theses and Dissertations

Water scarcity is a global reality and with the anticipated population growth, freshwater resources will be further strained to meet both human needs and agriculture applications. To ensure a water sustainable and food secure future, all aspects of agriculture must become more efficient. Two strategies were explored. The potential of improving water efficiency in broilers was examined. The first strategy was to develop a more efficient and accurate method for measuring water consumption/inputs in agriculture. To date, water measuring technology has lacked the necessary sophistication to assure accuracy and repeatability of low flow water usage.

After establishing a low flow …

A Staged Approach To Address Youth Unresponsive To Initial Obesity Intervention: A Randomized Clinical Trial, Katherine R Arlinghaus, Daniel P O'Connor, Tracey A Ledoux, Sheryl O Hughes, Craig A Johnston

Children’s Nutrition Research Center Staff Publications

Background/objective: Maintenance interventions inherently require BMI improvement to maintain. This overlooks individuals initially unresponsive to obesity interventions. Staged pediatric clinical treatment guidelines were adapted to the school setting to develop an escalated treatment option for individuals initially unresponsive. This staged randomized controlled trial examined differences between escalated treatment (Take CHARGE!) and a maintenance program (PE Planners). Take CHARGE was hypothesized to have greater improvements in BMI as a percentage of the 95th BMI Percentile (%BMIp95) than PE Planners.

Subjects/methods: From 2018 to 2020, 171 middle and high schoolers (BMI Percentile ≥ 85) were recruited from a Houston school district to …

Obesity is primarily a consequence of consuming calories beyond energetic requirements, but underpinning drivers have not been fully defined. 5-Hydroxytryptamine (5-HT) neurons in the dorsal Raphe nucleus (5-HTDRN) regulate different types of feeding behavior, such as eating to cope with hunger or for pleasure. Here, we observed that activation of 5-HTDRN to hypothalamic arcuate nucleus (5-HTDRN → ARH) projections inhibits food intake driven by hunger via actions at ARH 5-HT2C and 5-HT1B receptors, whereas activation of 5-HTDRN to ventral tegmental area (5-HTDRN → VTA) projections inhibits non-hunger-driven feeding via actions at 5-HT2C receptors. Further, hunger-driven feeding gradually activates ARH-projecting 5-HTDRN …

Children’s Nutrition Research Center Staff Publications

Optimizing enteral nutrition for premature infants may help mitigate extrauterine growth restriction and adverse chronic health outcomes. Previously, we showed in neonatal pigs born at term that lean growth is enhanced by intermittent bolus compared with continuous feeding. The objective was to determine if prematurity impacts how body composition, muscle protein synthesis, and myonuclear accretion respond to feeding modality. Following preterm delivery, pigs were fed equivalent amounts of formula delivered either as intermittent boluses (INT; n = 30) or continuously (CONT; n = 14) for 21 days. Body composition was measured by dual-energy X-ray absorptiometry (DXA) and muscle growth was …

American Bullfrog (Lithobates Catesbeianus) Diet In Uruguay Compared With Other Invasive Populations In Southern South America, Gabriel Laufer, Noelia Gobel, Mauro Berazategui, Matías Zarucki, Sofía Cortizas, Alvaro Soutullo, Claudio Martinez Debat, Rafael O. De Sá

Biology Faculty Publications

Between 2000-2020, more than ten new populations of the invasive American bullfrog (Lithobates catesbeianus) have been reported in the southern cone of South America. We studied the stomach contents of 126 bullfrogs from a population at an early invasion stage in Uruguay (Acegua, Cerro Largo Department). We observed a rich diet, with extensive prey volume range (1 mm3 to more than 7 000 mm(3)); the most frequent items were Hymenoptera (19.6%), Coleoptera (16.4%), Amphipoda (13.3%), Anura (8.9%) and Heteroptera (8.7%). Despite some overlap, differences were observed in volume (chi(2) = 54.6, p <0.001, d.f. = 2) and prey quantity (F = 8.1, p <0.001, d.f. = 79) between males, females, and juveniles. Juveniles showed significantly higher consumption of terrestrial prey by count (82% of their total ingestion) than adults (29% for males and 32% for females) (chi(2) = 28.5, p <0.001, d.f. = 2). Adults, especially females, showed a high frequency of cannibalism (33% of their total ingestion; chi(2) = 20.9, p <0.001, d.f. = 2). Comparing our data with other bullfrog regional studies, we found great plasticity in trophic habits and differences in the incidence of cannibalism (higher incidence in the populations of Acegua, Uruguay, and Buenos Aires, Argentina). These differences could be related to local biodiversity, but also could be affected by the invasion phase. Cannibalism frequency was higher in small bullfrog populations, where it could be favoring the establishment success. This shift in foraging strategies during the invasion process had been insufficiently evaluated in amphibians. Knowing the ecological determinants for the invasion by bullfrogs can be useful to the development of management strategies.

Influence Of External Ph And Organic Acids On Internal Ph And Acid Anion Accumulation In Listeria Monocytogenes And Escherichia Coli, Savannah R. Branson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Listeria monocytogenes and Escherichia coli are both among the most common microbial pathogens that cause foodborne illnesses and death. They both are capable of growing over a wide range of conditions. Organic acids are widely employed in the food industry to control growth of these pathogens to help prevent foodborne illnesses. There is substantial evidence that intracellular accumulation of organic acid anions is a major inhibitor to cell growth, and that many bacteria may combat anion accumulation by lowering their intracellular pH (pH_i). In this study, we followed the accumulation of acid anion into the cell pellet and …
