The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks Mar 2019

The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks

Dissertations

This study examined the relationship between distress and the development of Type 2 diabetes mellitus (T2DM) in the presence of established risk factors. Distress secondary to mental health disparities, stressful life events, and work conditions has been shown to promote insulin resistance and the development of T2DM.

Subjects (N=79) diagnosed with T2DM within the previous six months were recruited from SSM Health Centers and VA Medical Centers in the greater St. Louis area. They completed the Recent Life Changes Questionnaire, ENRICHD Social Support Instrument, and a demographic survey and analyses were conducted to determine differences between the veteran and ...


Deciphering The Consequences Of Yolk Testosterone Metabolism In Birds, Nicole A. Campbell Mar 2019

Deciphering The Consequences Of Yolk Testosterone Metabolism In Birds, Nicole A. Campbell

Theses and Dissertations

Maternal steroids transferred to eggs can elicit permanent effects on various aspects of offspring phenotype. Although, testosterone was thought to be a key mediator of maternal effects in birds, we now know that vertebrate embryos actively regulate their exposure to maternal testosterone through steroid metabolism, suggesting testosterone metabolites may elicit the observed phenotypic effects. To address the role steroid metabolism plays in mediating yolk testosterone effects, we used European starling (Sturnus vulgaris) eggs to characterize the timing of testosterone metabolism and determine whether etiocholanolone, a prominent testosterone metabolite in avian embryos, is capable of influencing early embryonic development. Tritiated testosterone ...

Associations Between Income, Acculturation, Country Of Origin, And Type Ii Diabetes Among African Immigrants To Ontario, Canada, Girma Aman Goshe

Walden Dissertations and Doctoral Studies

Diabetes has become a longstanding public health challenge around the world. Over the last 3 decades, the number of people with Type II diabetes (T2DM) has grown to an epidemic level in Canada. Prior research indicated African immigrants residing in Ontario, Canada experienced a 2-4 times higher prevalence of T2DM than Canadian-born individuals. The social determinants of health theoretical framework guided this study assessing the relationship of the risk factors with T2DM. A quantitative, cross-sectional design was employed using the 2007-2014 Canadian Community Health Survey data. The random sample included 1,526 African immigrants residing in Ontario, Canada. Descriptive, bivariate ...


Evaluation Of Endothelial Cell Responses To Elevated Glucose, Gabriella Sugerman Aug 2018

Evaluation Of Endothelial Cell Responses To Elevated Glucose, Gabriella Sugerman

Master's Theses and Project Reports

Developing a tissue-engineered Blood Vessel Mimic (BVM) to represent diabetic macrovascular disease could expedite design of new vascular devices specifically tailored to diabetic patients. In contribution toward this model, this thesis assessed Human Umbilical Vein Endothelial Cell (HUVEC) responses to high glucose conditions. Interleukin 6 (IL-6) and Cluster of Differentiation 36 (CD36) were selected to signify oxidative stress activity, a hallmark of diabetic macrovascular disease. Next, activity of potential reference genes B2M, HPRT1, and ACTB was assessed. All genes were found to exceed acceptable variability, so the E-ΔC T method of data analysis was selected. Next, cellular responses to high ...

Markers Of Cardiometabolic Risk And Thyroid Dysfunction In U.S. Adolescents: Nhanes Iii, Jonathan Austin

Theses and Dissertations

The global prevalence of metabolic syndrome (MetS) and its associated components (high fasting glucose, waist circumference, blood pressure, triglycerides, and low HDL) have increased over the past few decades. In addition, abnormal thyroid hormone levels have been found to manifest in a cascade of metabolic dysfunction, which may be linked to MetS in youth. PURPOSE: The purpose of the study is to investigate the association between MetS, its components, and markers of thyroid function in a nationally-representative sample of adolescents. METHODS: The National Health and Nutrition Examination Survey III (1988-1994) collected data on the components of metabolic syndrome and thyroid ...


Mechanisms And Potential Therapy On Disrupted Blood Pressure Circadian Rhythm In Diabetes, Tianfei Hou Jan 2018

Mechanisms And Potential Therapy On Disrupted Blood Pressure Circadian Rhythm In Diabetes, Tianfei Hou

Theses and Dissertations--Pharmacology and Nutritional Sciences

Arterial blood pressure (BP) undergoes a 24-hour oscillation that peaks in the active day and reaches a nadir at night during sleep in humans. Reduced nocturnal BP fall (also known as non-dipper) is the most common disruption of BP circadian rhythm and is associated with increased risk of untoward cardiovascular events and target organ injury. Up to 75% of diabetic patients are non-dippers. However, the mechanisms underlying diabetes associated non-dipping BP are largely unknown. To address this important question, we generated a novel diabetic db/db-mPer2Luc mouse model (db/db-mPer2Luc) that allows quantitatively measuring of mPER2 protein oscillation ...


Effects Of Income And Education Levels On Diurnal Cortisol In Black And White American Youth Transitioning Into Adulthood, Shannin Nicole Moody Jan 2018

Effects Of Income And Education Levels On Diurnal Cortisol In Black And White American Youth Transitioning Into Adulthood, Shannin Nicole Moody

Graduate Theses and Dissertations

Cortisol patterns differ across both socioeconomic status and racial minority groups. Yet, whether the underlying constructs that are used to measure socioeconomic status impacts the output of cortisol differentially across racial groups is unclear. Using a secondary data analysis from the Parents Who Care longitudinal study, which integrated the biomarker cortisol as youth entered emerging adulthood, the goal of this thesis is to parse apart the common conflation of income and education into a single catchall variable.

The following data was collected in 2 waves from a group of youth who were (M=20.24; R=18.51-22.89) years ...


Oral Glucose Insulin Secretion Test For Identifying Patients With Insulin Resistance, David Kershner Jan 2018

Oral Glucose Insulin Secretion Test For Identifying Patients With Insulin Resistance, David Kershner

Walden Dissertations and Doctoral Studies

Insulin resistance is an increasing public health issue with the current literature, suggesting reduced sensitivity of insulin leads to adult onset diabetes and associated downstream pathologies that reduce life expectancy. The main objectives of this study were to evaluate the ability of the Oral Glucose Insulin Secretion Test (OGIST) to identify insulin resistance and examine differences in the insulin sensitivity based on gender, age, and ethnicity. This study was supported by the insulin resistance theory which focuses on the reduced ability of insulin to bind to the cellular insulin receptor, reducing the sensitivity of insulin. The OGIST lab results of ...


The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey Dec 2017

The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey

Senior Theses and Capstone Projects

Type 1 Diabetics have various ways of managing their diabetes that have been studied for their effectiveness. Pregnancy in the Type 1 Diabetic has been understudied. It is known that Diabetics in general have poorer pregnancy outcomes because of poor glycemic control. This coupled with the fact that the body needs 3-4 times more insulin as pregnancy comes to an end makes managing blood glucose levels challenging for diabetics (Lowdermilk, 2016, p. 689). For the Type 1 Diabetic, there are two main ways to control diabetes: multiple daily injections using at least two type of insulin and continuous subcutaneous insulin ...

Theses & Dissertations

This study was conducted to determine if 15 minutes of postprandial light walking has an effect on the glycemic response to a Boost® beverage in individuals with type 1 diabetes. Seven participants, 22.3 + 4.3 yrs, with type 1 diabetes completed the two days of data collection. On day 1, participants measured baseline fasting blood glucose (BG) with a glucometer, consumed a Boost® beverage, and sat quietly, repeating BG measurements 15, 30, 60, 90, and 120 minute. On day 2, participants repeated the protocol, but walked 15 minutes at a light pace (50-60% max HR) immediately after beverage consumption ...


The Role Of Progesterone Receptor Membrane Component 1 In Receptor Trafficking And Disease, Kaia K. Hampton Jan 2017

The Role Of Progesterone Receptor Membrane Component 1 In Receptor Trafficking And Disease, Kaia K. Hampton

Theses and Dissertations--Pharmacology and Nutritional Sciences

The progesterone receptor membrane component 1 (PGRMC1) is a multifunctional protein with a heme-binding domain that promotes cellular signaling via receptor trafficking, and is essential for some elements of tumor growth and metastasis. PGRMC1 is upregulated in breast, colon, lung and thyroid tumors. We expanded the analysis of PGRMC1 in the clinical setting, and report the first analysis of PGRMC1 in human oral cavity and ovarian tumors and found PGRMC1 to correlate with lung and ovarian cancer patient survival. Furthermore, we discovered a specific role for PGRMC1 in cancer stem cell viability. PGRMC1 directly associates with the epidermal growth factor ...

Rice Consumption And Effects Of Rice Cake, Seolgitteok, On Human Health, Ellen Joy Pottgen

Theses and Dissertations

Within the United States type 2 diabetes is an ever growing health epidemic. The prevalence in the adult population has quadrupled over the past 30 years and is expected to continue on a similar path in the coming decades. While the cause of type 2 diabetes is multifactorial, it is considered to be an acquired condition related to environmental contributors including poor diet, obesity, and physical inactivity, which may be managed to alter the course or progression of the disease. Preventative or maintenance measures emphasize nutritional intervention strategies, including encouraging individuals to follow a nutrient-dense, high-fiber diet with ample whole-grains ...


The Effects Of Pulmonary Hypertension In Diabetic Zucker Rats On Pulmonary Vascular Contraction And Right Ventricular Size, Michael Franzetti May 2016

The Effects Of Pulmonary Hypertension In Diabetic Zucker Rats On Pulmonary Vascular Contraction And Right Ventricular Size, Michael Franzetti

Biological Sciences Undergraduate Honors Theses

Pulmonary hypertension is a life-threatening disease that is identified by a resting mean pulmonary arterial pressure over 25 mmHg and established by right heart catheterization (Saglam et al., 2015). The symptoms commonly associated with pulmonary hypertension include fatigue, dyspnea, syncope, and chest pain, which severely limit quality of life in diagnosed patients (Saglam et al., 2015). According to recent studies in patients with pulmonary hypertension, the one, three and five year mortality rates are 8%, 25%, and 34%, respectively (Burudpakdee, Shah, Joish, Divers, & Yaldo, 2014). Although some advances have been made in therapies for pulmonary hypertension, the prognosis is still ...


Estrogens Impair Antitumor Immunity By Promoting The Accumulation Of Myeloid-Derived Suppressor Cells, Nikolaos Svoronos Jan 2016

Estrogens Impair Antitumor Immunity By Promoting The Accumulation Of Myeloid-Derived Suppressor Cells, Nikolaos Svoronos

Publicly Accessible Penn Dissertations

Estrogens are pleiotropic steroid hormones with pro- and anti-inflammatory effects that influence autoimmune disease and pregnancy. Both autoimmunity and pregnancy are similar to cancer with regard to the immune system. In established tumors, as is the case in autoimmune disease and pregnancy, the host is exposed to self or allogeneic antigens, which are capable of eliciting immune responses. However, for pregnancies to remain viable, autoimmune disease patients survive, and tumors to persist, the immune system must be at least partially tolerized to these challenges. Therefore, I hypothesize that, just as they appear to influence pregnancy and autoimmunity, estrogens’ ability to ...

Investigation Of Pancreatic Β-Cell Insulin Receptor Regulation Of Β-Cell Growth, Function, And Survival Via A Temporal Conditional Knockout, Liangyi Zhou Aug 2015

Investigation Of Pancreatic Β-Cell Insulin Receptor Regulation Of Β-Cell Growth, Function, And Survival Via A Temporal Conditional Knockout, Liangyi Zhou

Electronic Thesis and Dissertation Repository

The expression of insulin receptor (IR) in β-cells suggests an autocrine role for insulin signalling in β-cell function and regulation. Studies have demonstrated that β-cell Ir knockout (βIrKO) mice develop age-dependent glucose intolerance. We investigated the temporal role of β-cell IR signaling in pre- and postnatal islet development and function, and under high-fat diet stress, using a tamoxifen-inducible Cre-recombinase Ir knockout mouse model.

Prenatal βIrKO mice exhibited increased mean islet area, β-cell area, and islet area percentage. Additionally, there was upregulation of insulin-like growth factor-2 levels, increased Akt activity, and increased proliferation in islets. Postnatally-induced βIrKO mice did not exhibit ...


Endothelial Driven Inflammation In Metabolic Disease: A Dissertation, Anouch Matevossian Feb 2015

Endothelial Driven Inflammation In Metabolic Disease: A Dissertation, Anouch Matevossian

GSBS Dissertations and Theses

Obesity has been on the rise over the last 30 years, reaching worldwide epidemic proportions. Obesity has been linked to multiple metabolic disorders and co-morbidities such as Type 2 Diabetes Mellitus (T2DM), cardiovascular disease, non-alcoholic steatohepatitis and various cancers. Furthermore, obesity is associated with a chronic state of low-grade inflammation in adipose tissue (AT), and it is thought that insulin resistance (IR) and T2DM is associated with the inflammatory state of AT.

Endothelial cells (ECs) mediate the migration of immune cells into underlying tissues during times of inflammation, including obesity- and cardiovascular disease-associated inflammation. Cytokines and chemoattractants released from inflamed ...

Establishing The Needs Of Type 1 Diabetes Users For Mobile Application Design, Amanda J. Skinner

Graduate Theses and Dissertations

Living with Type 1 diabetes as a child presents a great deal of responsibilities at a young age. These responsibilities require knowledge of the disease, constant monitoring, awareness, and more. A variety of mobile applications have been created to aid children with these responsibilities, but a thorough investigation of these users' needs is a missing piece that is not often, if at all, conducted. This research aims to understand these users' needs in great depth in order to offer appropriate design guidelines for a mobile application to aid in the daily management and medical adherence of a child living with ...


Innate Immune Cell Regulation Of Metabolic Homeostasis, Jonathan Brestoff Jan 2015

Innate Immune Cell Regulation Of Metabolic Homeostasis, Jonathan Brestoff

Publicly Accessible Penn Dissertations

Obesity is an increasingly prevalent disease regulated by genetic and environmental factors. Emerging studies indicate that immune cells, including monocytes, granulocytes and lymphocytes, regulate metabolic homeostasis and are dysregulated in obesity. Group 2 innate lymphoid cells (ILC2s) can regulate adaptive immunity and eosinophil and alternatively-activated macrophage responses, and were recently identified in murine white adipose tissue (WAT) where they may act to limit the development of obesity. However, ILC2s have not been identified in human adipose tissue, and the mechanisms by which ILC2s regulate metabolic homeostasis remain unknown. Here, we identify ILC2s in human WAT and demonstrate that decreased ILC2 ...

Open Access Theses & Dissertations

The impact of restraint stress on changes in cytokine expression and oxidative stress markers in hippocampal (Hipp) and hypothalamic (Hyp) regions of the brain, were assessed in a rat model. In addition, immune and inflammatory variables were assessed in peripheral blood. Male Wistar rats were acutely (30 min) or repeatedly (30 min/d for 14 consecutive days) exposed to a restraint stress, or maintained as non-stressed controls. At the time of sacrifice, whole blood and brain tissues enriched in Hyp or Hipp regions were collected; blood was collected with EDTA as an anticoagulant and centrifuged to yield plasma. All tissue ...


Development Of A Yeast-Based Assay For The Functional Characterization Of Fkbp52/ Î?-Catenin Interactions With The Androgen Receptor, Theresa Anne Rodriguez Jan 2015

Development Of A Yeast-Based Assay For The Functional Characterization Of Fkbp52/ Î?-Catenin Interactions With The Androgen Receptor, Theresa Anne Rodriguez

Open Access Theses & Dissertations

Prostate cancer development is uniquely dependent on the androgen receptorâ??s (ARâ??s) transcriptional regulation in response to hormone binding. Current therapies directly target AR acting as an antagonist at androgen binding sites. However, once androgen-dependence is lost, meaning the patient has progressed into a late-stage hormone resistant phenotype, all current treatments are essentially ineffective. Utilizing the yeast strain Saccharomyces cerevisiae we are capable of creating a model system that allows for the exogenous expression of AR while still retaining the chaperone components needed for this steroid receptor complex. The 52kDa FK506 binding protein (FKBP52) has been shown to be ...


Awareness Of Diabetes Risk Associated With Individuals 18 And Older, Rebecca Jane Boone Jan 2015

Awareness Of Diabetes Risk Associated With Individuals 18 And Older, Rebecca Jane Boone

Walden Dissertations and Doctoral Studies

The risk of developing Type 2 diabetes is increasing at epidemic proportions, and is 12-17% higher in Marion County Florida than it is across the state, based on Florida Department of Health statistics. The purpose of this DNP project was to determine if awareness of individual risk of developing Type 2 diabetes through a questionnaire would result in high-risk participants agreeing to attend a diabetes prevention program (DPP) at a local medical clinic. The health belief model and Rosswurm and Larrabee's model for change were used as frameworks. The review of the literature showed that prevention programs were highly ...


Cellular And Molecular Mechanisms Of Chemical-Induced Ovarian Toxicity, Shanthi Ganesan Jan 2014

Cellular And Molecular Mechanisms Of Chemical-Induced Ovarian Toxicity, Shanthi Ganesan

Graduate Theses and Dissertations

The ovary is the ovum-producing female reproductive organ composed of follicles at different stages of development. Chemicals which selectively damage large growing or antral follicles only temporarily interrupt reproductive function because these follicles can be replaced by recruitment from the greater pool of primordial follicles. However, chemicals that destroy oocytes contained in primordial follicles can cause permanent infertility and premature ovarian failure (early menopause in women), since once a primordial follicle is destroyed, it cannot be replaced. We hypothesized that ovotoxic chemicals can bind to DNA to induce DNA damage and that the ovarian cells activate DNA repair, cell cycle ...


The Effects Of Heat Stress On Energetic Metabolism And Insulin Homeostasis, María Victoria Sanz Fernández Jan 2014

The Effects Of Heat Stress On Energetic Metabolism And Insulin Homeostasis, María Victoria Sanz Fernández

Graduate Theses and Dissertations

Heat stress (HS) is a major environmental hazard for human health and animal agriculture. Changes in metabolism and specifically altered insulin action appear to be critical for the adaptation and ultimately survival to a severe heat load. However, our knowledge of the physiological and metabolic consequences of HS is woefully insufficient. Understanding the biology of HS is critical in order to develop treatment protocols and mitigation strategies against its deleterious effects on both humans and livestock. Interestingly, HS elicits a metabolic profile that somewhat resembles models of endotoxemia/sepsis. Moreover, HS negatively affects intestinal health and the subsequent increase in ...


Maintaining Glucose Homeostasis In Response To Aging And Stress: The Role Of Pcif1, Bmi1, And Pdx1, Corey Elizabeth Cannon Jan 2014

Maintaining Glucose Homeostasis In Response To Aging And Stress: The Role Of Pcif1, Bmi1, And Pdx1, Corey Elizabeth Cannon

Publicly Accessible Penn Dissertations

A sufficient number of functioning beta cells is necessary for maintaining glucose homeostasis. Reduction of beta cell mass or function leads to diabetes. Investigation into the maintenance of both beta cell mass and function is important for the development of therapies to prevent and/or restore functional beta cells. Here, the networks surrounding three proteins in the beta cell, Pcif1, Bmi1, and Pdx1, were studied as they relate to beta cell function and number. The Polycomb protein, Bmi1, has been shown to influence beta cell replication via epigenetic repression of the Ink4a/Arf locus, resulting in suppression of p16 protein ...

Participants from a convenience sample were randomized into two groups, one receiving education through conversation maps and the other through traditional group education. Participants’ knowledge and attitude changes were measured by using a repeated measures pre-test/post-test design and changes in Hb A1c were observed. Focus groups were conducted after education was received to obtain perceptions and self-reported behaviour changes. Significant knowledge and attitude score changes were observed in the conversation map group after education. When comparing ...


Interactions Of Nitric Oxide And Superoxide Pathways In Hyperglycemic Endothelial Cells, Steven Clay Rogers May 2012

Interactions Of Nitric Oxide And Superoxide Pathways In Hyperglycemic Endothelial Cells, Steven Clay Rogers

Theses and Dissertations

Cardiovascular complications arising from diabetic hyperglycemia represents one of the leading causes of death and greatest public health challenges of modern societies. Despite state-of-the-art glucose control, diabetic patients remain at a markedly increased risk of cardiovascular disease. The loss of endothelial function (the development of diabetic endothelial dysfunction) has been implicated in the development of numerous diabetic cardiovascular diseases. The endothelial cell produces many vasoactive substances, hormones and cytoprotective biological factors. Endothelial cells are also involved in and affected by the initiation of inflammatory responses through the release and interaction of cytokines and other immune system molecules. Therefore, regulation of ...
