Free Fatty Acid Treatment Alters Autophagy During Mouse Preimplantation Embryo Development, Zuleika C. L. Leung
Free Fatty Acid Treatment Alters Autophagy During Mouse Preimplantation Embryo Development, Zuleika C. L. Leung
Electronic Thesis and Dissertation Repository
Obesity-induced hyperlipidemia is one of the main factors for female infertility. Hyperlipidemia, specifically with high levels of palmitic acid (PA) and oleic acid (OA), interferes with preimplantation development. Autophagy is essential in early embryo development but, it is unknown whether hyperlipidemia affects autophagic mechanisms in preimplantation embryos. It was hypothesized that PA will alter autophagy in preimplantation mouse embryos and that the subsequent effects will be reversed by OA. PA impaired blastocyst development by arresting embryos at the 8-cell stage. PA also elevated early embryo autophagy by increasing autophagosome formation, decreasing maturation, and disrupting degradation. Co-treatment with OA showed developmental …
Racial And Socioeconomic Disparities Influencing Obesity Amongst Middle-Aged Women, Morgan Woods
Racial And Socioeconomic Disparities Influencing Obesity Amongst Middle-Aged Women, Morgan Woods
Master of Science in Integrative Biology Theses
Many studies have examined the effects of racial and socioeconomic differences on health-related disparities involving obesity but, few have examined the mental and physical well-being intersection. Obesity is a disease that affects many Americans and has become an epidemic affecting the American population. Obesity, especially morbid obesity, is a risk factor for many other obesity-related diseases such as diabetes, cardiovascular diseases, hypertension, and more. Using the 2018 Healthcare Avoidance Study, differences were found between two racial groups, Caucasian and African-American women. Race was found as a significant factor for both level of physical activity and ideal body image perception
Exploring Β-Cell Function And Heterogeneity In Obese Sm/J Mice, Mario Alejandro Miranda
Exploring Β-Cell Function And Heterogeneity In Obese Sm/J Mice, Mario Alejandro Miranda
Arts & Sciences Electronic Theses and Dissertations
Pancreatic β-cells perform glucose-stimulated insulin secretion, a process required to maintain systemic glucose homeostasis. Obesity promotes glycemic and inflammatory stress, causing β-cell death and dysfunction, resulting in diabetes. Efforts to improve β-cell function in obesity have been hampered by observations that β-cells are highly heterogeneous, varying in morphology, function, and gene expression. There is great need to understand the breadth of β-cell heterogeneity in health and obesity to improve diabetic therapies.High fat-fed SM/J mice spontaneously transition from hyperglycemic-obese to normoglycemic-obese with age, providing a unique opportunity to study β-cell adaptation. Here, we show that as they resolve hyperglycemia, obese SM/J …
Obesity Prevention Toolkit To Combat Weight Gain Related To Sedentary Behavior And Dietary Habits In College Students: An Evidence-Based Project, Maria Amos, Martha Fuller

Abstract
Background: Forty percent of the US population ages 20-39 are categorized as obese,
their BMI is over 30, and 35% of college age students are obese or overweight. Issues related to obesity cost the US $147 billion annually. Between 40%-50% of college students are reported to be inactive. Inactivity can lead to increased morbidity and mortality related to increased risks of cardiovascular disease, diabetes, hypertension, musculoskeletal issues, and depression. Providing dietary and physical activity education and access to nutritional information promotes behavior change in young adults.
Aims of Service Change: This evidence-based project proposal aims to provide a toolkit …
Human Regulatory T Cells Control Inflammation From Effector T Cells In Prediabetes, Rui Liu
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 …

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. …
