Brown And Beige Adipocytes: Effects Of Inflammation And Nutritional Intervention, Jiyoung Bae
Brown And Beige Adipocytes: Effects Of Inflammation And Nutritional Intervention, Jiyoung Bae
Doctoral Dissertations
Recent findings of brown adipocytes and brown-like or beige adipocytes, capable of dissipating energy as heat, in adult humans have promised new hope for obesity treatment and prevention. Understanding of the regulation of brown and beige adipocytes will provide novel strategies to reach the goal. Pattern recognition receptors (PRR) are responsible for inflammation in adipose tissue, which leads to adipose dysfunction and obesity associated chronic diseases. It has been shown that PRR activation induces inflammation, leading to insulin resistance in white adipocytes and white adipose tissue (WAT). However, the roles of PRR activation in brown adipocytes and brown adipose tissue …
Diabetes Status, Predisposing, Enabling, And Oral Health Illness Level Variables As Predictors Of Preventive And Emergency Dental Service Use, Sabha Alshatrat
Diabetes Status, Predisposing, Enabling, And Oral Health Illness Level Variables As Predictors Of Preventive And Emergency Dental Service Use, Sabha Alshatrat
Health Services Research Dissertations
The purpose of this study was to clarify the relationship between diabetes and dental service use. This study addressed the question of whether individuals with diabetes are more or less likely to utilize dental services, measured in terms of preventive and emergency services during the past year. A cross-sectional study was conducted to assess the contributions of diabetes status to dental service use, relative to the contributions of Andersen and Newman Framework of Health Services Utilization dimensions (predisposing, enabling, and illness variables) in predicting dental service utilization during the past year using a nationally representative sample from a 2001-2002 National …
Non-Invasive Determination Of Pre-Clinical Markers Of Cardiovascular Diseases In Low Birth Weight And Maternal Western Diet Guinea Pig Offspring Exposed To A Postnatal Western Diet, Jacky Chiu
Electronic Thesis and Dissertation Repository
Low birth weight (LBW), and maternal Western Diet (WD) consumption have both been independently implicated to increase the risk of developing cardiovascular diseases (CVDs) in later life. These fetal programmed risks are also believed to exacerbate the effects of a postnatal WD pattern. Therefore, resulting in the development of pre-clinical markers of CVDs, such as insulin resistance (IR), coronary circulation disruptions. This thesis aimed to elucidate the roles of sub-optimal in utero growth through placental insufficiency, or chronic maternal WD consumption, and postnatal WD consumption on the long-term programming of CVDs in a guinea pig model. Early pre-clinical markers of …
Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga
Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga
Arts & Sciences Electronic Theses and Dissertations
Objective: Phenylketonuria (PKU) is a hereditary metabolic disorder associated with cognitive compromise. Diffusion tensor imaging (DTI) has allowed detection of poorer microstructural white matter integrity in children with PKU, with decreased mean diffusivity (MD) in comparison with healthy children. However, very little research has been conducted to examine the trajectory of white matter development in this population. The present study investigated potential differences in the developmental trajectory of MD between children with early- and continuously-treated PKU and healthy children across a range of brain regions.
Methods: Children with PKU (n = 31, mean age = 12.2 years) were …
Raising Awareness: Polycystic Kidney Disease, Dana Dendinger
Raising Awareness: Polycystic Kidney Disease, Dana Dendinger
Nursing Student Class Projects (Formerly MSN)
A young male patient was recently admitted to the intensive care unit at a local hospital with hypertensive urgency and acute renal failure of unknown etiology. A renal ultrasound showed polycystic kidneys and upon further investigation, it was discovered that the patient’s mother passed away last year from end stage renal failure related to polycystic kidney disease (PKD). The aforementioned case and the recent study into inherited disorders are what prompted further investigation into PKD. Liebau and Serra (2013) explain that “inherited cystic kidney diseases, autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD), are the …
Molecular Mechanisms Linking Amino Acid (Leucine) Deprivation To Igfbp-1 Hyperphosphorylation In Fetal Growth Restriction, Niyati M. Malkani
Molecular Mechanisms Linking Amino Acid (Leucine) Deprivation To Igfbp-1 Hyperphosphorylation In Fetal Growth Restriction, Niyati M. Malkani
Electronic Thesis and Dissertation Repository
In this study, we explore the molecular mechanisms linking amino acid (leucine) deprivation to IGFBP-1 hyperphosphorylation in vitro. During pregnancy, a maladaptive fetal response to in utero amino acid deprivation leads to Fetal Growth Restriction (FGR). FGR infants display elevated phosphorylated IGFBP-1, which is associated with decreased IGF-I bioavailability. Leucine deprivation inhibits mechanistic target of rapamycin (mTOR) signaling and stimulates the amino acid response (AAR). Using HepG2 cells, a model for fetal hepatocytes, we demonstrate that in leucine deprivation, the AAR modulates total and phosphorylated IGFBP-1 while mTOR mediates total IGFBP-1 secretion only. We also reveal that protein kinases …

The Effect Of Run Sprint Interval Training On Diabetic Metabolic Markers In Prediabetic Adults, Kathryn L. Hilovsky
Masters Theses, 2010-2019
Abstract
Purpose: The primary purpose of this study was to compare the effects of an 8-week run-sprint interval training (R-SIT) and continuous moderate-intensity training (MIT) on fasting blood glucose, HbA1c, insulin sensitivity, and β-cell function in sedentary, prediabetic adults. Secondary outcomes of the study included anthropometric, body composition variables, and aerobic capacity.
Methods: Sedentary, physician diagnosed prediabetic individuals were randomized into R-SIT (n=7, BMI 36.76 ± 9.79) or MIT (n=8, BMI 40.59 ± 12.49) interventions. Subjects participated in supervised exercise three times a week and attended a Diabetes Prevention Program course, once weekly. R-SIT participants performed 4-6 x 30-second …
A Translational Study Determining The Impact Of Timing And Duration Of Aerobic Walking On Metabolic Control And Personal Preferences Among Adults Recently Diagnosed With Type 2 Diabetes, Cory Cox
Graduate Theses
Type 2 diabetes (T2D) is a potentially life threatening metabolic disease characterized by insulin resistance and inability to metabolize glucose (Meneilly & Elliott 1999). According to the American Diabetes Association (ADA, 2013), diabetes played a contributing role in 231,404 deaths in 2007 alone. Because of this, researchers strive to develop the best methods of managing diabetes. Physical activity has been shown to improve glucose control by reducing insulin resistance and reducing body fat (Bacchi et al., 2012). Recent data from DiPietro et al. (2013) indicated that multiple bouts of exercise may be favorable over one continuous bout in managing blood …
Diabetic Bone Marrow & Stem Cell Dysfunction, Meghan A. Piccinin
Diabetic Bone Marrow & Stem Cell Dysfunction, Meghan A. Piccinin
Electronic Thesis and Dissertation Repository
ii Abstract Abstract Defects in the proliferation, differentiation, and activity of bone marrow (BM)-derived vasculogenic/vascular stem cells (VSCs) have been observed in diabetes and contribute to the development of vascular complications. Diabetes leads to enhanced bone marrow adipogenesis, altering the composition of the BM stem cell (SC) niche and potentially disrupting the normal functioning of resident VSCs. Here, I establish that adipocytes have a negative influence on SC survival in culture. I also show that adipocytes and osteoblasts are responsible for the creation of distinct extracellular microenvironments, with unique expression patterns of several pro- and anti-angiogenic factors with known effects …
The Effect Of Aerobic Exercise Training On Hepatic Glycogen Metabolism In Type 1 Diabetic Rats, Michael Murray
The Effect Of Aerobic Exercise Training On Hepatic Glycogen Metabolism In Type 1 Diabetic Rats, Michael Murray
Electronic Thesis and Dissertation Repository
The purpose of this investigation was to determine if ten weeks of aerobic exercise training could increase hepatic glycogen storage in rats with Type 1 Diabetes Mellitus (T1DM) and whether elevated hepatic glycogen content is associated with alterations in glycogenic proteins and insulin signaling. Rats were divided into control-sedentary, control-exercised, T1DM-sedentary and T1DM-exercised groups. Animals from each group underwent a euglycemic-hyperinsulinemic clamp at the conclusion of the study. Exercise training consisted of treadmill running at 27m/min, 6% incline for 1hr, five days/week for ten weeks. T1DM rats had lower liver glycogen concentrations than control rats and glycogen was not increased …

Impact Of Starch Source On Equine Hindgut Microbial Ecology, Brittany Elizabeth Davis Harlow
Impact Of Starch Source On Equine Hindgut Microbial Ecology, Brittany Elizabeth Davis Harlow
Theses and Dissertations--Animal and Food Sciences
Grain inclusion in equine diets can allow starch to reach the hindgut where bacteria compete for the substrate. The hypothesis was that starch introduction would cause a source-dependent press disturbance in equine fecal microflora. Fecal cell suspensions were prepared by differential centrifugation and re-suspension in media with ground corn, oats or wheat. At 24 h, corn had more amylolytics and Group D Gram-positive cocci (GPC), and fewer lactate-utilizing (LU) bacteria and lactobacilli than oats, with wheat being intermediate. Predominant amylolytics were identified by their 16S RNA gene sequence as Enterococcus faecalis (corn, wheat) and Streptococcus bovis (oats). In an in …
Regulation Of Pancreatic Β-Cell Function By The Renin-Angiotensin System In Type 2 Diabetes, Robin C. Shoemaker
Regulation Of Pancreatic Β-Cell Function By The Renin-Angiotensin System In Type 2 Diabetes, Robin C. Shoemaker
Theses and Dissertations--Pharmacology and Nutritional Sciences
Diet-induced obesity promotes type 2 diabetes (T2D). Drugs that inhibit the renin-angiotensin system (RAS) have been demonstrated in clinical trials to decrease the onset of T2D. Previously, we demonstrated that mice made obese from chronic consumption of a high-fat (HF) diet have marked elevations in systemic concentrations of angiotensin II (AngII). Pancreatic islets have been reported to possess components of the renin-angiotensin system (RAS), including angiotensin type 1a receptors (AT1aR), the primary receptor for AngII, and angiotensin converting-enzyme 2 (ACE2), which negatively regulates the RAS by catabolizing AngII to angiotensin-(1-7) (Ang-(1-7)). These two opposing proteins have been implicated in the …

Potential Role Of Protein Kinase Cbeta In High Fat Diet-Induced Adipose Dysfunction By Regulating Autophagy Levels, Neil Mehta
Williams Honors College, Honors Research Projects
Obesity is the most common nutritional disorder in the United States and worldwide. Public health efforts and other anti-obesity measures clearly have not controlled the obesity epidemic. There is a great need to understand the pathogenic mechanisms underlying fat accumulation. Research of the past decade supports a prominent role for diet-induced adipose tissue dysfunction in the development and/or progression of obesity and associated insulin resistance. Potential mechanisms for the development of adipose tissue dysfunction include ectopic (visceral) fat accumulation, genetic factors, and alterations in autophagy and inflammatory processes. However, the molecular mechanisms linking dietary fat intake with alterations in adipose …
