The Role Of Secretory Phospholipase A2 Group Iia In Obesity And Metabolism, Michael S. Kuefner Aug 2019

The Role Of Secretory Phospholipase A2 Group Iia In Obesity And Metabolism, Michael S. Kuefner

Theses and Dissertations (ETD)

Secretory phospholipase A2 group IIA (PLA2G2A) is a member of a family of secretory phospholipases previously implicated in inflammation, atherogenesis, and antibacterial actions. These enzymes hydrolyze glycerophospholipids at the sn-2 position releasing lysophospholipids and fatty acids. Though studies have shown PLA2G2A is pro-inflammatory and promotes atherosclerosis, no research has analyzed the role of this enzyme in obesity and metabolism. Studies in the past 5-10 years utilizing various knock- out or over-expression mouse models have analyzed the role of different secretory phospholipase A2s (sPLA2) in metabolic diseases. From these studies, it is known that at least seven of the 11 sPLA2 ...

Respondents ...


Physical Activity Of Preschoolers With Developmental Disabilities And Delays, Michaela A. Schenkelberg Jul 2019

Physical Activity Of Preschoolers With Developmental Disabilities And Delays, Michaela A. Schenkelberg

Theses and Dissertations

Children with developmental disabilities and delays are at greater risk for developing overweight and obesity compared to typically developing peers. Participation in regular physical activity is a modifiable behavior that is consistently associated with improved weight status and other positive health outcomes. Previous studies have identified numerous individual- and environmental-level factors that associate with physical activity among school-age children with and without disabilities. However, little is known about physical activity behaviors and related correlates among preschool-aged children with disabilities (ages 3 – 5 years), especially while they are in preschool settings. Therefore, the overall purpose of this dissertation was to describe ...


Oleic Acid Attenuates Palmitic Acid-Induced Impairments In Mouse Blastocyst Development, Maisoon Dafalla Yousif Jun 2019

Oleic Acid Attenuates Palmitic Acid-Induced Impairments In Mouse Blastocyst Development, Maisoon Dafalla Yousif

Electronic Thesis and Dissertation Repository

Palmitic acid (PA) and oleic acid (OA) are the most abundant saturated and monounsaturated non-esterified fatty acids, respectively, in serum. The consequences of PA and OA treatment on preimplantation mouse embryo development were investigated. It was hypothesized that OA treatment from the two-cell stage onwards would attenuate PA-induced reductions in mouse blastocyst development. PA significantly reduced development to the blastocyst stage. Transcript analysis revealed that PA increased ER stress pathway markers activating transcription factor 3 and C/EBP homologous protein transcripts, and XBP1 splicing. Co-culture of PA-treated embryos with OA prevented this PA-induced ER stress and rescued blastocyst development. Cytoplasmic ...


Effects Of Eat Better, Move More (Ebmm) Educational Program On Obesity Rates In Latino Children Residing In Northwest Arkansas, Allison Jones May 2019

Effects Of Eat Better, Move More (Ebmm) Educational Program On Obesity Rates In Latino Children Residing In Northwest Arkansas, Allison Jones

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Background: Childhood obesity, especially in ethnic minority populations, is a growing problem with no signs of improvement over the past decade. The Latino population is one of the fastest growing minority groups in the United States. Unfortunately, they have experienced substantial health disparities and socioeconomic disadvantages that contribute to the high rates of obesity in their youth. Decreasing obesity rates would not only have many health advantages, but also financial benefits as well. It would reduce the risk of co-morbidities such as cardiovascular disease and depression. Healthy children are more likely to grow into healthy adults, ultimately lowering the cost ...


Association Of Dietary Behaviors, Macro-Nutrients And Energy Intake With Body Fat Percentage, Lean Mass, And Bone Mineral Density., Makayla Goggins May 2019

Association Of Dietary Behaviors, Macro-Nutrients And Energy Intake With Body Fat Percentage, Lean Mass, And Bone Mineral Density., Makayla Goggins

Health, Human Performance and Recreation Undergraduate Honors Theses

Background: Due to the obesity epidemic, many studies have compared nutrient intake to human body composition. However, previous studies have not used gold standard measures of body composition in a college population. Purpose: The purpose of this study is to examine how dietary behaviors, overall energy intake, and macronutrient intake are associated with the body composition factors measured in a dual-energy x-ray absorptiometry (DXA) scan. We hypothesize higher body fat percentage will be associated with higher fat and carbohydrate intake, but not total energy intake. Methodology: This was a cross-sectional study done as part of Exercise is Medicine® On Campus ...

The aim of this study is to evaluate weight-related eating behaviors of participants with clinically significant weight loss (CSWL) in a proprietary weight loss program. A crosssectional sample of participants (n=1,454) enrolled in a proprietary weight-loss program that includes meal replacements and health coaching were queried for weight-related eating behaviors (using Weight Related Eating Questionnaire) of routine restraint (RR), compensatory restraint (CR), susceptibility to external cues (SEC), and emotional eating (EE) in relation to CSWL (defined as having achieved a weight loss greater than 10% of starting weight). Participants were dichotomized into those with CSWL (n=973) and ...


Sugar- Sweetened Beverages: A Survey To Assess Adults Knowledge, Attitudes, And Consumption Patterns Of Sugar-Sweetened Beverages, Jeff Schafer Jan 2019

Sugar- Sweetened Beverages: A Survey To Assess Adults Knowledge, Attitudes, And Consumption Patterns Of Sugar-Sweetened Beverages, Jeff Schafer

All Theses, Dissertations, and Other Capstone Projects

Sugar-sweetened beverages (SSBs) have a direct impact on the general health of the country when looking at the rising obesity levels (CDC, 2017a). The USDA’s dietary guidelines suggest that the daily intake of added sugar should be limited to 6 teaspoons for women and 9 teaspoons for men (Hughes, 2017). However, the average American consumes 20 teaspoons of sugar daily (Hughes, 2017). These extra calories are converted into fat and stored in the body. Data collected throughout the years indicates a rise in the number of Americans living with a weight above healthy recommendations, which is termed, obese. Obesity ...

Male Weight Control: Crowdsourcing And An Intervention To Discover More, Tiffany Rounds Jan 2019

Male Weight Control: Crowdsourcing And An Intervention To Discover More, Tiffany Rounds

Graduate College Dissertations and Theses

Men and women have similar rates of obesity but the combined prevalence of overweight and obesity is higher among men. Men who are overweight are a high-risk group for many obesity-related chronic diseases, as they are more likely to carry excess weight in the abdomen, which is generally more harmful than weight stored in the lower body. Men are also less likely than women to perceive themselves as overweight, and thus are less likely to initiate weight loss through organized weight loss programs. On average, less than 27% of weight loss trial participants have been men.

Internet-based research is a ...

Effect Of Grain Sorghum Polyphenols On Fecal Fermentation, Danielle Marie Ashley

Theses and Dissertations

Obesity is an increasing epidemic which during 2015-2016 afflicted 39.8% of adults and 18.5% of youth in the United States. Not only can obesity affect quality of life, but it can lead to life-threatening diseases such as type 2 diabetes, heart disease, stroke, and some cancers. Animal and human research have demonstrated a pattern of gut microbiota perturbation in overweight and obesity, characterized by a reduction of beneficial bacterial species and increase in harmful species. Diet has been established as a contributing factor in gut ecology, and foods including fiber, resistant starch, and polyphenols have been found to ...


An Evaluation Of Alzheimer's Disease-Related Pathology In Two Different Models Of Diabetes In Immune-Challenged Mice, Andrew Scott Murtishaw Aug 2018

An Evaluation Of Alzheimer's Disease-Related Pathology In Two Different Models Of Diabetes In Immune-Challenged Mice, Andrew Scott Murtishaw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Obesity, type 2 diabetes mellitus (T2DM), and metabolic syndrome are related disorders with wide-ranging and devastating effects that can be observed throughout the body. One important and understudied organ of damage is the brain. Clinical and epidemiological studies have found that T2DM, and more specifically hyperinsulinemia, significantly increases the risk of cognitive decline and increases the likelihood of Alzheimer’s disease (AD) and other forms of dementia in the elderly. Insulin has slightly different functions in the peripheral body than in the central nervous system and the dysregulation of these functions may contribute to the onset and progression of late-life ...


Dsba-L Protein Levels In White Adipose Tissue In An Obesity Model., Madison E. Kerley May 2018

Dsba-L Protein Levels In White Adipose Tissue In An Obesity Model., Madison E. Kerley

College of Arts & Sciences Senior Honors Theses

Adiponectin is an adipose tissue-secreted protein found in three isoforms. Disulfide bond A oxidoreductase-like protein (DsbA-L) is thought to assist with protomeric disulfide bonding to generate the HMW (high molecular weight) isoform, which regulates insulin sensitivity. Both adiponectin and DsbA-L were previously found to negatively correlate with obesity.

Immunoblots were conducted on adipose tissue samples from male mice fed a high or low-fat diet for 6, 10, or 16 weeks. Immunoblots from high-fat diet-fed mice revealed double bands for DsbA-L. High and low molecular weight bands were analyzed together, revealing significantly higher relative band densities with 10 and 16-week high-fat ...


Hypothalamic Mechanisms Underlying The Cardiovascular And Metabolic Actions Of Leptin, Balyssa Bridget Bell May 2018

Hypothalamic Mechanisms Underlying The Cardiovascular And Metabolic Actions Of Leptin, Balyssa Bridget Bell

Theses and Dissertations

Secreted by adipose tissue, leptin acts as a signal of energy reserve status, and acts in the brain as a negative feedback mechanism to suppress food intake and increase energy expenditure, the net effect of which is maintenance of energy homeostasis. In addition to its role as a satiety factor, leptin has widespread autonomic effects, increasing sympathetic tone to a variety of tissues, including those involved in arterial pressure regulation. Thus, leptin has been implicated as a critical link between obesity and hypertension. However, the specific mechanisms whereby leptin elicits its diverse effects are not fully understood. This is further ...


Effects Of Mitochondrial Nadp+-Dependent Isocitrate Dehydrogenase Deficiency On Fructose-Induced Obesity In Mice, Allison Michelle Montalbano, Kaleigh Elizabeth Beane May 2018

Effects Of Mitochondrial Nadp+-Dependent Isocitrate Dehydrogenase Deficiency On Fructose-Induced Obesity In Mice, Allison Michelle Montalbano, Kaleigh Elizabeth Beane

Human Nutrition and Hospitality Management Undergraduate Honors Theses

Obesity prevalence in the United States continues to increase and is associated with health consequences such as type 2 diabetes, hypertension, atherosclerosis, and hyperlipidemia. Among many contributing factors to obesity, fructose may be one of the major reasons as it disrupts the antioxidant system thereby resulting in an accumulation of reactive oxidative species and leading to obese conditions. The enzyme, isocitrate dehydrogenase 2 (IDH2), reduces nicotinamide adenine dinucleotide phosphate from the TCA Cycle, hence might be implicated with not only energy metabolism but also cellular redox homeostasis. Therefore, the hypothesis was that IDH2 deficiency in mice would exacerbate hepatic lipid ...


Relationship Between Food Intake And Expression Of O-Linked N-Acetylglucosamine Transferase Messenger Rna In Channel Catfish, Oaklee Abernathy May 2018

Relationship Between Food Intake And Expression Of O-Linked N-Acetylglucosamine Transferase Messenger Rna In Channel Catfish, Oaklee Abernathy

Master's Theses

Food intake regulation is a complex neural process that involves the coordination of multiple mechanisms. O-linked N-acetylglucosamine transferase (OGT) is a neural nutrient sensor that aids in regulating satiety in mammals. Compared to mammals, little is known about function and regulation of OGT expression in fish. It was hypothesized changes in food intake are associated with changes in OGT expression in channel catfish. The objectives of this study were to examine tissue distribution of OGT mRNA and determine the possible relationship between food intake and OGT mRNA in channel catfish. Screening of the catfish genome database yielded four highly homologous ...

Assessment Of Nutrition Knowledge And Dietary Behaviors Of Post Bariatric Surgery Patients Attending The Outpatient Clinic Of Rashid Hospital, Dubai, Souheir Mahmoud Alia

Food Science Theses

Obesity is regarded as an increasingly prevalent public health problem, with enormous adverse health consequences. It also increases the risk for co-morbidities. There are several means to treat obesity, and bariatric surgery has emerged as one of the most prevalent ways to treat obesity. Despite the vast research assessing nutrition knowledge of patients regarding several health conditions, existing research assessing the nutrition knowledge of post-bariatric surgery patients is limited, although this category of patients is very susceptible to malnutrition post-surgery. The aim of this study was to assess the patients’ general nutrition knowledge and the knowledge specific to the dietary ...


Isolating, Characterizing And Enumerating Cell-Derived Microparticles: Relevance In Health And Disease, Tyler Daniel Bammert Jan 2018

Isolating, Characterizing And Enumerating Cell-Derived Microparticles: Relevance In Health And Disease, Tyler Daniel Bammert

Integrative Physiology Graduate Theses & Dissertations

Microparticles are small (0.1-1.0 μm in diameter) extracellular vesicles derived from the plasma membrane of activated and/or apoptotic cells. Once thought to be inert cellular debris, microparticles are now recognized as important paracrine/endocrine vectors involved in the transcellular exchange of physiological and pathological information. Moreover, microparticles play key roles in the development of atherosclerotic cardiovascular disease and may serve as sensitive biomarkers of disease risk, progression, severity and outcome. Critical to the utility of microparticles as biomarkers of vascular health and disease is the isolation, characterization and enumeration of these submicron vesicles. A central feature of ...

Clinical And Therapeutic Significance Of Obesity In Melanoma, Jennifer L. Mcquade Aug 2017

Clinical And Therapeutic Significance Of Obesity In Melanoma, Jennifer L. Mcquade

UT GSBS Dissertations and Theses (Open Access)

While the FDA approval of targeted and immune therapies in metastatic melanoma (MM) have dramatically improved outcomes in this disease, de novo and/or acquired resistance can limit the clinical benefit of these agents. The IGF-1/PI3K/AKT pathway has been implicated in resistance to both targeted and immune therapy. The IGF-1/PI3K/AKT pathway has also been shown to play a key role in the pathogenesis of obesity in other malignancies. To date, the impact of energy balance on clinical outcomes and therapeutic response in MM has not been studied. I hypothesized that energy balance would impact the molecular ...

The Linkage Between Hpa Axis Dysregulation And Metabolic Syndrome, Brianna Godlewski Jun 2017

The Linkage Between Hpa Axis Dysregulation And Metabolic Syndrome, Brianna Godlewski

Honors Theses

A diagnosis of Metabolic Syndrome (MSX) requires patients to present with three or more of the following symptoms: elevated fasting blood glucose levels, elevated serum triglyceride levels, low serum HDL levels, elevated blood pressure, and truncal obesity. This pathology shares many similarities with Cushing’s Syndrome (CS) but a diagnosis of CS requires hypercortisolemia. This similarity has led our lab and others to hypothesize that MSX may be a Cushingoid-like state caused by hypersensitivity of the glucocorticoid receptor (GR), a nuclear hormone receptor that is activated when cortisol binds, and or hyperactivity of the enzyme 11beta-hydroxysteroid dehydrogenase (11?- HSD) type ...


Development Of Novel Allele Specific Pcr Based Assays To Investigate The Contribution Of Cortisol To Metabolic Syndrome And It's Potential Implications In Depression Treatment, Justin Robert Salm Jun 2017

Development Of Novel Allele Specific Pcr Based Assays To Investigate The Contribution Of Cortisol To Metabolic Syndrome And It's Potential Implications In Depression Treatment, Justin Robert Salm

Honors Theses

The shared circuitries of depression and the stress response, regulated by the Hypothalamic-Pituitary-Adrenal (HPA) axis, implies that major depression may reflect dysregulations of the HPA axis. Previous studies find that that melancholic depression is accompanied by hyperactive HPA activity, anxiety, insomnia etc. Adversely, patients with atypical depression present CRH deficiency accompanied by lethargy and fatigue. According to the corticosteroid receptor hypothesis, HPA axis dysregulation that causes these variable phenotypic depressive moods may be attributed to defective GR expression or function. Multiple GR polymorphisms that could impact its expression or function have been identified. Due to limitations, it was not feasible ...
