Gpr75 Deficiency Attenuates High Fat Diet-Driven Obesity And Glucose Intolerance, Sakib Hossain
Gpr75 Deficiency Attenuates High Fat Diet-Driven Obesity And Glucose Intolerance, Sakib Hossain
NYMC Student Theses and Dissertations
Recently, a collaboration between Regeneron Pharmaceuticals and the Schwartzman-Garcia labs at New York Medical College published an exome sequencing study of individuals across the United Kingdom, United States, and Mexico which concluded that individuals possessing non-functioning, truncated mutations to the orphan g protein coupled receptor (GPCR), GPR75, had lower BMI and 54% reduced likelihood of obesity. The present study was undertaken to fully characterize the metabolic phenotype of Gpr75 deficient mice when fed a high fat diet (HFD) and explore potential mechanisms by which GPR75 activation links to increased adiposity and decreased glucose tolerance. After 14 weeks of HFD-feeding we …

UNLV Theses, Dissertations, Professional Papers, and Capstones
The World Health Organization has classified childhood obesity as one of the most serious public health concerns in the world. Obesity is known to have detrimental health consequences and be a risk for comorbidities. On top of the consequences of obesity already seen in young children at school, a lack of health education interventions in many elementary schools remains a significant health disparity. Anatomy Academy (AA) is a seven-week curriculum designed to educate children about their bodies and the importance of gaining and maintaining a healthy lifestyle. The purpose of this service-learning project was to educate elementary school students in …

Open Access Theses & Dissertations
Background: In the perspective of preventing cardiovascular disease and promoting health, weight control and physical activity are the main concerns. Electrical stimulation (ES) is an alternate strategy to induce muscle contraction, using electrical impulses. However, effectiveness of ES induced muscle contraction to improve energy expenditure and glucose metabolism is not well examined.Purpose: To determine the acute effect of ES on whole body energy expenditure and body glucose metabolism in sedentary overweight or obese population Methods: Sedentary overweight/obese participants (n=8; age: 37.25 ± 6.09 years; BMI= 37.57 ± 2.43 kg/m2) were included in this study. All participants received bilateral quadriceps ES …
Brown Adipose Tissue (Bat) Activation And Its Potential Utilization As A Treatment Option For Obesity And Diabetes, Darcie B. Schneider
Brown Adipose Tissue (Bat) Activation And Its Potential Utilization As A Treatment Option For Obesity And Diabetes, Darcie B. Schneider
Student Publications
Within the human body, there are two types of adipose tissue: white adipose tissue (WAT) and brown adipose tissue (BAT). WAT is beneficial for insulation whereas BAT has thermogenic capacity. BAT activation increases energy consumption via heat generation. Increased energy expenditure is associated with improved glucose and lipid metabolism. Therefore, BAT activation research has primarily been aimed at its potential use in the treatment of obesity, diabetes, and other metabolic disorders. In this literature review, BAT's thermogenic mechanisms, techniques of activation, potential therapeutic targets, and future research topics are explored.

Scaling Of Computed Tomography Body Composition To Height: Relevance Of Height-Normalized Indices In Patients With Colorectal Cancer, Justin C. Brown, Steven B. Heymsfield, Bette J. Caan
School of Medicine Faculty Publications
Background: Body weight scales to height with a power of ≈2 (weight/height2), forming the basis of body mass index (BMI). The corresponding scaling of body composition measured by abdominal computed tomography (CT) to height has not been established. The objective of this analysis was to quantify the scaling of body composition measured by a single-slice axial abdominal CT image (skeletal muscle, and visceral, subcutaneous, and total adipose tissue) to height in patients with colorectal cancer (CRC). Methods: This cross-sectional study included non-Hispanic white males and females, aged 18–80 years, who were diagnosed with stage I–III CRC at an integrated health …
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 …
Effect Of High Intensity Interval Training Vs Low Intensity Training On Fat Loss In Patients With Obesity, Jonathan Aaron Deck, Adarsh Gupta
Effect Of High Intensity Interval Training Vs Low Intensity Training On Fat Loss In Patients With Obesity, Jonathan Aaron Deck, Adarsh Gupta
Rowan-Virtua Research Day
Nowadays, there are several exercise modalities to lose weight, retain, and or build lean body mass. A widely known training philosophy that has gained increased popularity is high intensity interval training (HIIT). HIIT is based on exercising at submaximal or maximal intensity for a brief period then reducing work to minimal intensity for a longer duration in a series of repeated bouts. The benefit of HIIT is to increase fat loss through the scientific principle of EPOC (excess post exercise oxygen consumption). Low intensity training (LIT) also has its benefits in that it is more sustainable but with the caveat …
Cold-Induced Metabolic Changes In Lean, Nag-1 Transgenic Mice, Rachel J. Davey
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. …

Energy Cost Of Land And Shallow Water Walking In Females Who Are Overweight And Obese, Jacquelyn N. Zera, Elizabeth F. Nagle, Bethany B. Gibbs, John P. Abt, John M. Jakicic
International Journal of Aquatic Research and Education
Nineteen overweight or obese females completed three 10-minute experimental trials including a self-selected pace shallow water walking trial, a matched heart rate response land walking trial, and a self-selected pace land walking trial. Energy expenditure (kcal·min-1)was computed from expired gases assessed via indirect calorimetry. Results showed energy expenditure was lower (p= 0.046) during shallow water walking (6.46 ± 1.38 kcal·min-1) compared to matched heart rate response land walking trial (7.26 ± 1.29 kcal·min-1), with no significant difference in between shallow water and self-selected pace land walking (6.92 ± 1.61 kcal·min-1). …

Pre-training muscle characteristics of subjects who are obese determine how well exercise training will improve their insulin responsiveness. J Strength Cond Res 31(3): 798–808, 2017—Only half of prediabetic subjects who are obese who underwent exercise training without weight loss increased their insulin responsiveness. We hypothesized that those who improved their insulin responsiveness might have pretraining characteristics favoring a positive response to exercise training. Thirty nondiabetic subjects who were obese volunteered for 8 weeks of either strength training or endurance training. During training, subjects increased their caloric intake to prevent weight loss. Insulin responsiveness by euglycemic clamps and muscle fiber composition, …

Rising Rural Body-Mass Index Is The Main Driver Of The Global Obesity Epidemic In Adults, Con Burns, Tara Coppinger, Janette Walton, Et Al
Publications
Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities1,2. This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity3,4,5,6. Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to …

Regulation of lipid absorption by enterocytes can influence metabolic status in humans and contribute to obesity and related complications. The intracellular steps of chylomicron biogenesis and transport from the Endoplasmic Reticulum (ER) to the Golgi complex have been described, but the mechanisms for post-Golgi transport and secretion of chylomicrons have not been identified. Using a newly generated Dennd5b−/− mouse, we demonstrate an essential role for this gene in Golgi to plasma membrane transport of chylomicron secretory vesicles. In mice, loss of Dennd5b results in resistance to western diet induced obesity, changes in plasma lipids, and reduced aortic atherosclerosis. In …

Adipose tissue macrophages have been proposed as a link between obesity and insulin resistance. However, the mechanisms underlying these processes are not completely defined. Calpains are calcium-dependent neutral cysteine proteases that modulate cellular function and have been implicated in various inflammatory diseases. To define whether activated calpains influence diet-induced obesity and adipose tissue macrophage accumulation, mice that were either wild type (WT) or overexpressing calpastatin (CAST Tg), the endogenous inhibitor of calpains were fed with high (60% kcal) fat diet for 16 weeks. CAST overexpression did not influence high fat diet-induced body weight and fat mass gain throughout the study. …

Background: Circadian rhythms are characterized by approximate 24-hour oscillations in physiological and behavioral processes. Disruptions in these endogenous rhythms, most commonly associated with shift work and/or lifestyle, are recognized to be detrimental to health. Several studies have demonstrated a high correlation between disrupted circadian rhythms and metabolic disease. The aim of this study was to determine which metabolic parameters correlate with physiological measures of circadian temperature amplitude (TempAmp) and stability (TempStab).
Methods: Wrist skin temperature was measured in 34 subjects (ages 50 to 70, including lean, obese, and diabetic subjects) every 10 minutes for 7 consecutive days. Anthropometric measures and …

The Validity Of Submaximal Exercise Testing In Obese Women, Gabrielle Ringenberg
Mahurin Honors College Capstone Experience/Thesis Projects
Background: Submaximal exercise tests use heart rate responses to low-to-moderate intensity activity in order to predict cardiorespiratory fitness (VO2max). Currently used tests may be inappropriate for obese populations as obese women have altered heart rate responses to exercise. The purpose of this project is to test the validity of the Modified Bruce Protocol submaximal treadmill test in obese women. Methods: Normal-weight (NWG) and obese women (OBG) completed the Modified Bruce submaximal treadmill test (to predict VO2max using previously validated equations) and a maximal graded exercise test on a treadmill using the Standard Bruce Protocol (to obtain an …

The heart possesses a remarkable inherent capability to adapt itself to a wide array of genetic and extrinsic factors to maintain contractile function. Failure to sustain its compensatory responses results in cardiac dysfunction, leading to cardiomyopathy. Diabetic cardiomyopathy (DCM) is characterized by left ventricular hypertrophy and reduced diastolic function, with or without concurrent systolic dysfunction in the absence of hypertension and coronary artery disease. Changes in substrate metabolism, oxidative stress, endoplasmic reticulum stress, formation of extracellular matrix proteins, and advanced glycation end products constitute the early stage in DCM. These early events are followed by steatosis (accumulation of lipid droplets) …

Apolipoprotein E4 And Insulin Resistance Interact To Impair Cognition And Alter The Epigenome And Metabolome, Lance A. Johnson, Eileen Ruth S. Torres, Soren Impey, Jan F. Stevens, Jacob Raber
Physiology Faculty Publications
Apolipoprotein E4 (E4) and type 2 diabetes are major risk factors for cognitive decline and late onset Alzheimer’s disease (AD). E4-associated phenotypes and insulin resistance (IR) share several features and appear to interact in driving cognitive dysfunction. However, shared mechanisms that could explain their overlapping pathophysiology have yet to be found. We hypothesized that, compared to E3 mice, E4 mice would be more susceptible to the harmful cognitive effects of high fat diet (HFD)-induced IR due to apoE isoform-specific differences in brain metabolism. While both E3 and E4 mice fed HFD displayed impairments in peripheral metabolism and cognition, deficits in …

Assessing For Awareness And Knowledge Regarding Diabetes In Pre-Diabetes Obese Patients, Remona Lysa Brown
Walden Dissertations and Doctoral Studies
Over the past few decades, there has been an increase in prevalence of diabetes in the United States. Prevention of diabetes and improving patients' knowledge and awareness of diabetes are crucial for healthcare providers. Using the Health Belief Model (HBM) as a theoretical foundation, the student used the National Diabetes Prevention Program (NDPP) from the Centers for Disease Control and Prevention (CDC), to improve awareness and knowledge of diabetes among obese individuals with prediabetes. The key research question of this project was to determine whether the patients' diabetes knowledge and awareness improved after the NDPP program. A convenience sample of …

Central And Peripheral Weight Gain Affect Trunk Kinematics And Lower-Extremity Muscle Activation Differently During Sit-To-Stand, Michelle Christine Walaszek
Theses and Dissertations--Kinesiology and Health Promotion
Background: Obesity-induced alterations in biomechanics and muscle recruitment during activities of daily living, such as sit-to-stand (STS) are often attributed to increases in adipose tissue (AT) mass. Central or peripheral distribution of AT may differently affect biomechanics and muscle recruitment.
Methods: Fifteen healthy, normal weight (BMI 22.4 ± 1.9 kg/m2, 24.1 ± 4.2 years) subjects volunteered. External loads equivalent to a 5 kg/m2 BMI increase were applied in three conditions: unloaded (UN), centrally loaded (CL), and peripherally loaded (PL). Subjects completed three successful STS movements in a backless chair under each load condition in random order. Motion …

Exercise Ameliorates High Fat Diet Induced Cardiac Dysfunction By Increasing Interleukin 10., Varun Kesherwani, Vishalakshi Chavali, Bryan T. Hackfort, Suresh C. Tyagi, Paras K. Mishra
Journal Articles: Cellular & Integrative Physiology
Increasing evidence suggests that a sedentary lifestyle and a high fat diet (HFD) leads to cardiomyopathy. Moderate exercise ameliorates cardiac dysfunction, however underlying molecular mechanisms are poorly understood. Increased inflammation due to induction of pro-inflammatory cytokine such as tumor necrosis factor-alpha (TNF-α) and attenuation of anti-inflammatory cytokine such as interleukin 10 (IL-10) contributes to cardiac dysfunction in obese and diabetics. We hypothesized that exercise training ameliorates HFD- induced cardiac dysfunction by mitigating obesity and inflammation through upregulation of IL-10 and downregulation of TNF-α. To test this hypothesis, 8 week old, female C57BL/6J mice were fed with HFD and exercised (swimming …

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 samples …

Journal Articles: Cellular & Integrative Physiology
The management of recurrent pregnancy loss (RPL) still remains a great challenge, and women with polycystic ovarian syndrome (PCOS) are at a greater risk for spontaneous abortion. Treatment with low-molecular-weight heparin (LMWH) has become an accepted treatment option for women with RPL; however, the subgroup of women, who are likely to respond to LMWH, has not been precisely identified. The present study evaluated the efficacy of LMWH with reference to PCOS and associated metabolic phenotypes including hyperhomocysteinemia (HHcy), insulin resistance (IR) and obesity. This prospective observational study was conducted at Institute of Reproductive Medicine, Kolkata, India. A total of 967 …
Elongation Factor 1a-1 And Hepatocyte Response To Fatty Acid Excess, Alexandra M. Stoianov
Elongation Factor 1a-1 And Hepatocyte Response To Fatty Acid Excess, Alexandra M. Stoianov
Electronic Thesis and Dissertation Repository
Obesity is associated with elevated levels of serum fatty acids, which accumulate in nonadipose tissues including the liver. Elongation factor 1A-1 (EF1A-1) has previously been shown to participate in the cell stress and death response of cardiomyocytes to excess saturated fatty exposure, and in steatotic mouse myocardium. In this thesis, the hypothesis that the hepatocyte response to fatty acid overload involves EF1A-1 was tested. EF1A-1 expression was induced in the livers of obese mice in association with severe hepatic steatosis, and in HepG2 human hepatoma cells in response to excess palmitate. Partial translocation of EF1A-1 from the ER to polymerized …
Fatty Acid Fate In Determining Oxidation And Inflammation In Adipose Tissue, Emilio Patrick Mottillo
Fatty Acid Fate In Determining Oxidation And Inflammation In Adipose Tissue, Emilio Patrick Mottillo
Wayne State University Dissertations
Adipose tissue (AT) is a critical regulator of energy balance through its ability to store or oxidize free fatty acids (FFAs). White adipose tissue (WAT) functions as an anabolic organ to sequester and release FAs, in contrast brown adipose tissue (BAT) is a catabolic organ that oxidizes FAs. However, a comprehensive understanding of the role that FFAs play in the function of WAT and BAT is needed. Here we demonstrate that intracellular FAs enhance the expression of inflammatory cytokines by β3-AR activation in adipocytes, in which the expression of PAI-1 is partly mediated by the de novo synthesis of ceramides/sphingolipids. …
Linking Environmental Toxicant Exposure To Diabetes Susceptibility, Jannifer Beth Tyrrell
Linking Environmental Toxicant Exposure To Diabetes Susceptibility, Jannifer Beth Tyrrell
Wayne State University Dissertations
An important and unresolved question in the environmental health field is whether exposure to common environmental toxicants, such as dioxin and heavy metals like Pb, increase the risk of developing diabetes, especially in combination with other common metabolic stressors such as obesity.
Previous studies suggested that dioxin exposure increased peripheral insulin resistance but did not appear to cause fasting hyperglycemia or elevated hepatic glucose output. In concordance with those findings we observed that dioxin treatment caused a strong suppression of the expression of the key hepatic gluconeogenic genes PEPCK and G6Pase. However, this suppression was not solely mediated by the …

The Absence Of Abcd2 Reveals A Novel Role For Peroxisomes In The Protection From Metabolic Syndrome, Jingjing Liu
The Absence Of Abcd2 Reveals A Novel Role For Peroxisomes In The Protection From Metabolic Syndrome, Jingjing Liu
University of Kentucky Doctoral Dissertations
ABCD2 (D2) is a peroxisomal ATP binding cassette (ABC) transporter that is expressed in brain, adrenal and liver. D2 is transcriptionally regulated by key transcriptional factors that control lipid and glucose metabolism. Therefore, we examined its role in adipose tissue. These studies revealed that D2 is highly abundant in adipose tissue and upregulated during adipogenesis. However, D2 deficiency does not affect either adipogenesis or lipid accumulation. An examination of the lipid profile of adipose tissue revealed the accumulation of C20 and C22 fatty acids in D2 deficient (D2‐/‐) mice. When challenged with a diet enriched in erucic acid (C22:1, 10% …
