Dietary Assessments And Their Association With Psychological Factors, Inflammation, And Cardiovascular Health Outcomes, Junghee Kang

Theses and Dissertations--Nursing

Cardiovascular diseases (CVDs), a group of disorders of the heart and blood vessels, are the leading cause of death worldwide, causing one-third of deaths each year. Diet is one of the most important behavioral risk factors for CVD. The effects of behavioral risk factors, such as diet, may lead to increased blood pressure, increased blood glucose, raised blood lipids, and overweight and obesity. Inflammation contributes to the development of CVD and can be influenced by diet. Dietary assessment indices can measure diet quality from an individual's dietary intake by scoring food and nutrient intakes. However, the mediation effects of diet …

Physical Activity, Dietary Patterns, And Glycemic Management Of Active Individuals With Type 1 Diabetes: An Online Survey, Sheri Colberg, Jihan Kannane, Norou Diawara

Human Movement Studies & Special Education Faculty Publications

Individuals with type 1 diabetes (T1D) are able to balance their blood glucose levels while engaging in a wide variety of physical activities and sports. However, insulin use forces them to contend with many daily training and performance challenges involved with fine-tuning medication dosing, physical activity levels, and dietary patterns to optimize their participation and performance. The aim of this study was to ascertain which variables related to the diabetes management of physically active individuals with T1D have the greatest impact on overall blood glucose levels (reported as A1C) in a real-world setting. A total of 220 individuals with T1D …

Sex Differences In Peripheral Fat Detection And Metabolism, Naima Dahir

Electronic Theses and Dissertations, 2020-2023

The current epidemic of obesity is driven, at least in part, by excessive caloric intake and fat intake has been implicated as a major contributing factor. The mammalian taste system displays marked plasticity, and it has been shown that the detection of fatty acids, the prototypical fat taste stimulus, leads to reduced sensitivity upon prolonged exposure to a high-fat diet. Increased obesity and metabolic disorders in postmenopausal females indicate that the female steroid hormone, estrogen, may contribute to metabolic homeostasis. Sex differences in the taste system were explored using a multidisciplinary approach to examine the ways in which estrogen influences …

Dietary Phytoestrogens Ameliorate Hydrochloric Acid-Induced Chronic Lung Injury And Pulmonary Fibrosis In Mice, Pavel Solopov, Ruben Manuel Luciano Colunga Biancatelli, Christiana Dimitropoulou, John D. Catravas

Bioelectrics Publications

We previously reported that female mice exhibit protection against chemically induced pulmonary fibrosis and suggested a potential role of estrogen. Phytoestrogens act, at least in part, via stimulation of estrogen receptors; furthermore, compared to residents of Western countries, residents of East Asian countries consume higher amounts of phytoestrogens and exhibit lower rates of pulmonary fibrosis. Therefore, we tested the hypothesis that dietary phytoestrogens ameliorate the severity of experimentally induced pulmonary fibrosis. Male mice placed on either regular soybean diet or phytoestrogen-free diet were instilled with 0.1 N HCl to provoke pulmonary fibrosis. Thirty days later, lung mechanics were measured as …

Cost-Effectiveness Of Interventions Targeting Hard-To-Reach Populations Living With Hiv In Eastern And Southern Africa, Deo Mujwara

Theses and Dissertations

In Eastern and Southern Africa, hard-to-reach populations (e.g., long distance truck drivers and female sex workers), defined as populations that are difficult to interact or engage with due to their unique behaviors and characteristics, are disproportionately affected by the HIV epidemic and are at high-risk of acquiring and transmitting HIV. Further, these populations have substantially low uptake of HIV testing services, and those that have been diagnosed with HIV and on antiretroviral therapy experience high loss-to-follow-up from treatment programs.

Hard-to-reach populations face unique barriers in accessing and utilizing routine HIV care such as provider stigmatization towards sex workers and highly …

Predicting Tomorrow: Optimizing The Early Detection Of Disease And Disease Recovery In Dairy Calves Using Precision Technologies, Melissa Cantor

Theses and Dissertations--Animal and Food Sciences

The leading causes of morbidity and mortality in preweaned dairy calves are diarrhea and bovine respiratory disease complex (BRD). The delayed detection of these diseases in calves can also delay intervention and disease recovery. The overarching objective of this dissertation was to follow a cohort of calves daily for the first 90 days of life for naturally occurring clinical BRD bouts and diarrheal bouts. The objective answered if feeding behaviors and activity levels were different in at-risk calves during BRD development and BRD recovery from an antimicrobial intervention. Furthermore, the potential of colostrum replacer as a feeding intervention strategy to …

Effects Of Season And Nutrition On Insulinemic Responses In Insulin Dysregulated Horses, Erica Lyn Macon

Theses and Dissertations--Veterinary Science

Insulin dysregulation (ID) is the main risk factor for the development of hyperinsulinemia-associated laminitis (HAL). ID in the equid has been extensively researched; however, recommendations for diagnosing and managing ID horses have originated from work completed in other models, such as the ID pony and healthy horse. Therefore, our overall objective was to improve current diagnostic tools and nutritional management strategies by investigating the effect of season, the fed and fasted state on the oral sugar test (OST) and dietary nutrient content on insulinemic responses in the ID horse. To address this, four main objectives with three specific aims were …

Tick Ecdysteroid Hormone, Global Microbiota/Rickettsia Signaling In The Ovary Versus Carcass During Vitellogenesis In Part-Fed (Virgin) American Dog Ticks, Dermacentor Variabilis, Loganathan Ponnusamy, Haley Sutton, Robert D. Mitchell Iii, Daniel E. Sonenshine, Charles S. Apperson, Richard Michael Roe

Biological Sciences Faculty Publications

The transovarial transmission of tick-borne bacterial pathogens is an important mechanism for their maintenance in natural populations and transmission, causing disease in humans and animals. The mechanism for this transmission and the possible role of tick hormones facilitating this process have never been studied. Injections of physiological levels of the tick hormone, 20-hydroxyecdysone (20E), into part-fed (virgin) adult females of the American dog tick, Dermacentor variabilis, attached to the host caused a reduction in density of Rickettsia montanensis in the carcass and an increase in the ovaries compared to buffer-injected controls. This injection initiates yolk protein synthesis and uptake …

Using A Lubricin Reporter Cell To Test Current Vs. Optimized Media Compositions, Sean M. Kennedy

Honors Undergraduate Theses

Osteoarthritis is a joint disease characterized by the breakdown of articular cartilage. The field of tissue engineering is interested in developing methods to produce biological alternatives to current orthopedic procedures. Lubricin is a molecule which is important in the proper lubrication of articular cartilage. It is a challenge in the field of tissue engineering to produce cartilage with sufficient lubricin expression. Developing a reporter cell for lubricin allowed for a more efficient investigation of the conditions wh­­­ich may influence its expression. By comparing "optimized" and traditional media solutions, it was determined that the use of a previously reported type II …

Human Regulatory T Cells Control Inflammation From Effector T Cells In Prediabetes, Rui Liu

Theses and Dissertations--Pharmacy

Type 2 diabetes (T2D) is a chronic low-grade inflammatory disease. A T cell cytokine profile (Th17) from PBMCs can distinguish obese T2D from obese non-diabetes subjects. Individual T cell subsets interact with each other and the diverse subsets jointly determine overall inflammation. Cellular metabolism drives cytokine production of CD4⁺ T cells, and therefore contributes to inflammation in T2D. However, specific changes in metabolism and function of CD4⁺ T cells during the progression from lean healthy to obese and diabetic stages in people have not been clarified.

We hypothesize that human regulatory T cells (Treg) impact metabolism of effector …

Identification And Characterization Of Epitope Specific Immune Responses In Humans And Mice, David Henson

Theses and Dissertations--Pharmacy

Cardiovascular disease (CVD) is a major cause of morbidity and mortality around the world causing approximately 14% of total disease burden. A major factor in the progression to major CVD within patients is immune activation, which led to the study of various immune products as potential biomarkers for the prediction of cardiovascular events, including antigen-specific antibodies and immune complexes. One focus of this biomarker research is IgG autoantibodies targeting apolipoprotein A-I (ApoA-I), and several studies of these antibodies have found an association with increased CVD events. Based on the encouraging results from these studies and previous research which has identified …

The Gestation Of Health: Environmental Insults, Behavioral Interventions, And Protective Mechanisms, Brittany Breon Rice

Theses and Dissertations--Pharmacology and Nutritional Sciences

Diabetes remains a leading cause of death nationwide despite pharmacological advances. Recent etiological investigations of the disease detail the role of perinatal exposure to environmental contaminants, such as polychlorinated biphenyls (PCBs), in enhancing disease susceptibility. Polychlorinated biphenyl 126, a coplanar PCB, elicits its toxic effects through the aryl-hydrocarbon receptor and the disruption of endocrine signaling. The goal of this dissertation was to focus on delineating the differences in the developmental windows of diabetes susceptibility respective to the timing of PCB126 exposure and to understand the influence of maternal exercise and nuclear-factor erythroid-2-related factor 2 (Nrf2) expression in combating the negative …

An Assessment Of The Carrier State And A Novel Marker Of Leptospira And Abortion In Central Kentucky Horses, Gloria Louise Gellin

Theses and Dissertations--Veterinary Science

Leptospirosis is a reemerging zoonotic infection of worldwide importance and affects all mammals. The bacterium is transmitted to animals and humans by urine, fetal membranes and body fluids. Leptospira shedding in the urine contaminates both soil and water, exposing both humans and animals to the bacterium. Leptospirosis in horses can cause abortion and is one of the etiologies of equine recurrent uveitis which can lead to blindness. Equine leptospiral abortion in Central Kentucky is primarily caused by serovar Pomona, with occasional cases attributed to serovar Grippotyphosa. There are a few reports in the literature attributing abortion to serovar Bratislava in …

Structural Remodeling Of The Lumbar Multifidus, Thoracolumbar Fascia And Lateral Abdominal Wall Perimuscular Connective Tissues: Medium-Term Test-Retest Reliability Of Ultrasound Measures, Christian Larivière, Dany H. Gagnon, Richard Preuss

Études primaires

Abstract

Introduction

Growing interest is being paid to the lumbar multifidus (LM) intramuscular fatty infiltrations and fibrosis that are secondary to low back pain as well to the remodeling of perimuscular connective tissues (fasciae) such as the thoracolumbar fascia and fascia sheets separating the abdominalwall muscles. Magnetic resonanceimaging and computed tomography have traditionally been used but rehabilitative ultrasound imaging (RUSI) is much more affordable and practical, which can accelerate research and clinical applications on this topic. The aim of this study was to test the medium-term (8 weeks) test-retest reliability of the corresponding RUSI measures.

Cold-Induced Metabolic Changes In Lean, Nag-1 Transgenic Mice, Rachel J. Davey

All Master's Theses

Obesity is a multifaceted metabolic disorder with severe worldwide public health consequences. While obesity can often be treated using diet and exercise, there are complex genetic interactions driving obesity that don’t always respond to such changes. One important research focus for addressing genetic factors is activating brown adipose tissue which increases thermogenesis, the process of burning stored fats to generate heat. Cold exposure is a known way to activate brown adipose tissue through b3-adrenergic signaling. This signaling pathway causes an upregulation of thermogenesis in brown adipocytes and beige adipocytes, which is white adipose tissue that “browns” and becomes metabolically active. …

Mitochondrial Aspects Of Neuronal Pathology In Triple-Transgenic Alzheimer’S Disease Mice, John Zachary Cavendish

Graduate Theses, Dissertations, and Problem Reports (ETD)

Alzheimer’s disease (AD) is a fatal, progressive neurodegenerative disease afflicting millions of people in the United States alone and is the only one of the top leading causes of morbidity and mortality with no effective disease-modifying therapies. It is the most common form of dementia, affecting one in three people over the age of 85. While the hallmarks of the disease include accumulation of beta-amyloid-based extracellular plaques and hyperphosphorylated tau-based intracellular neurofibrillary tangles, treatment strategies centered on removing or mitigating these components of AD have all failed in humans. Mitochondrial dysfunction has been increasingly recognized as an early and consistent …

Pre-Clinical Advancements In Biomarkers, Tools, And Therapeutics For A Metabolic Neurodegenerative Disease, Zoë Simmons

Theses and Dissertations--Molecular and Cellular Biochemistry

Glycogen is the storage form of glucose and a highly important substrate for cellular metabolism. Characterization of the enzymes and mechanisms of glycogen metabolism began over 70 years ago and over the last 20 years, a previously unknown protein called laforin has emerged as an important contributor to glycogen metabolism homeostasis. Multiple labs demonstrated that laforin is a glycogen phosphatase and mutations in the gene encoding laforin cause the formation of aberrant glycogen-like aggregates called Lafora bodies (LBs). LBs are cytoplasmic, water-insoluble aggregates that drive neurodegeneration and early death in Lafora disease (LD) patients. The direct relationship between mutated laforin, …

Method: A mixed-method, single …

Microbiomes Of Blood-Feeding Arthropods: Genes Coding For Essential Nutrients And Relation To Vector Fitness And Pathogenic Infections. A Review, Daniel E. Sonenshine, Philip E. Stewart

Biological Sciences Faculty Publications

Blood-feeding arthropods support a diverse array of symbiotic microbes, some of which facilitate host growth and development whereas others are detrimental to vector-borne pathogens. We found a common core constituency among the microbiota of 16 different arthropod blood-sucking disease vectors, including Bacillaceae, Rickettsiaceae, Anaplasmataceae, Sphingomonadaceae, Enterobacteriaceae, Pseudomonadaceae, Moraxellaceae and Staphylococcaceae. By comparing 21 genomes of common bacterial symbionts in blood-feeding vectors versus non-blooding insects, we found that certain enteric bacteria benefit their hosts by upregulating numerous genes coding for essential nutrients. Bacteria of blood-sucking vectors expressed significantly more genes (p < 0.001) coding for these essential nutrients than those of non-blooding insects. Moreover, compared to endosymbionts, the genomes of enteric bacteria also contained significantly more genes (p < 0.001) that code for the synthesis of essential amino acids and proteins that detoxify reactive oxygen species. In contrast, microbes in non-blood-feeding insects expressed few gene families coding for these nutrient categories. We also discuss specific midgut bacteria essential for the normal development of pathogens (e.g., Leishmania) versus …

Identification Of Infant Feeding Practices In Eastern Kentucky And Southern West Virginia That Correlate With High Weight-For-Length, Havilah R. Adkins

DNP Projects

Background: Approximately 20% of children in the United States are obese. West Virginia and Kentucky rank in the top 10 for obesity rates in children as young as 2-4 years old. Obesity increases the risk for numerous short-term health problems and impacts long-term health, development, quality of life, and life expectancy. Research indicates that obesogenic behaviors can be addressed prior to the development of obesity or significant health problems to prevent, rather than treat. Interventions targeting caregivers of infants younger than 2-years can promote early development of healthy feeding habits that persist through the developmental stages of nutrition. Before a …
