The effects of statins on mitochondrial function
(East Carolina University, 2013)Statins, or 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, are among the most commonly prescribed medications in the United States. They are commonly used to treat hypercholesterolemia, a condition ... -
ESTABLISHMENT OF THE PYRUVATE DEHYDROGENASE COMPLEX AS A CENTRAL REGULATOR OF MITOCHONDRIAL REDOX WITHIN SKELETAL MUSCLE
(East Carolina University, 2013)Once regarded as "byproducts" of aerobic metabolism, the production of superoxide/H₂O₂ is now understood to be a highly specialized and extensively regulated process responsible for exerting control over a vast number of ... -
G Protein-Coupled Receptor Signaling in Growth and Inflammation of Vascular Smooth Muscle
(East Carolina University, 2021-06-22)Cardiovascular disease (CVD) remains the primary cause of morbidity and mortality in the United States and worldwide. The exaggerated release of serine proteases and reduced blood flow and ensuing development of extracellular ... -
IL-15 : A NOVEL REGULATOR OF LIPOLYSIS IN HUMANS?
(East Carolina University, 2014)Interactions between and within organ systems such as skeletal muscle (SkM) and adipose tissue (AT), via immune cell signaling factors (cytokines), may regulate the development of obesity. The increased expression and ... -
The induction of antigen-specific immunological tolerance and attenuation of inflammation via cytokine antigen fusion protein therapy in a mouse model of pulmonary inflammation
(East Carolina University, 2014)Allergic asthma is a significant medical issue, affecting more than 300 million individuals and causing approximately 250,000 deaths each year. Current asthma therapies temporarily minimize discomfort and manage symptoms, ... -
Influence of carbon nanomaterial exposure on pro-constrictor mechanisms during pregnancy
(East Carolina University, 2013)Engineered carbon based nanoparticles (CNP) such as fullerenes and multiwalled carbon nanotubes (MWCNTs) are increasingly used in industries and in nanomedicine as a platform for drug delivery. Following environmental/o ... -
The Influence of Energy Expenditure on Mitochondrial Functions, Oxidative Stress and Insulin Resistance under Metabolic Oversupply Conditions
(East Carolina University, 2011)Mitochondrial respiratory capacity and oxidative stress have been implicated in the development of insulin resistance (IR) and type II diabetes. A causative role of mitochondrial oxidative stress in the etiology of ... -
Intratracheal instillation of silver nanoparticles exacerbates cardiac ischemia/reperfusion injury in male sprague-dawley rats
(East Carolina University, 2014)The uses of engineered nanomaterials have expanded in biomedical technology and consumer manufacturing. Exposure to particulate matter has been demonstrated to negatively influence cardiovascular health and expand myocardial ... -
Measured Resting Energy Expenditure Using a Fixed Function Indirect Calorimeter in the Clinical Setting as a Predictor of Success with Weight Change in an Obese Pediatric Population
(East Carolina University, 2010)The American Dietetic Association (ADA) standard of care for obese adults utilizes indirect calorimetry for calculating caloric targets for weight loss (1). Even though rates appear to be leveling off (2), childhood obesity ... -
Metabolic Inflexibility in Skeletal Muscle With Obesity
(East Carolina University, 2009)The skeletal muscle of obese individuals has a reduced capacity to oxidize lipids. The hypothesis to be tested in this dissertation is that the ability to regulate lipid oxidation in response to lipid exposure is impaired ... -
Metabolic, Physiological, And Behavioral Responses Of Prey To Predation
(East Carolina University, 2015)Predators are known to cause prey to alter their morphology, life history or behavior in ways that reduce the likelihood of the prey being consumed by the predator. Seldom considered, however, are the consequences of ... -
Modulation of IKKβ with AMPK Improves Insulin Sensitivity in Skeletal Muscle
(East Carolina University, 2008-11)Activation of the insulin receptor substrate (IRS)-1 is necessary for proper transduction of the insulin signal. IRS-1 serine312(human)/307(rodent) phosphorylation, however, results in disruption of this signal and subsequent ... -
NADPH Oxidase as a Mechanistic Link Between Erectile Dysfunction, Peripheral, and Coronary Endothelial Dysfunction in Obesity
(East Carolina University, 2012)Cardiovascular complications involving both microvascular and macrovascular tissues are the major cause of morbidity and mortality in obese patients. Clinical and epidemiological studies suggest that erectile dysfunction ... -
NOVEL MECHANISMS GOVERNING SKELETAL MUSCLE MITOCHONDRIAL BIOENERGETICS : OXPHOS EFFICIENCY AND cAMP/PKA SIGNALING
(East Carolina University, 2014)Understanding the regulation of cellular metabolism is paramount to treating the growing prevalence of metabolic disease worldwide. In cellular metabolism, mitochondrial oxidative phosphorylation (OXPHOS) plays a key role ... -
Paternal diet and exercise epigenetically program energy expenditure and glucose metabolism in mouse offspring
(East Carolina University, 2014)It is currently estimated that a third of Americans suffer from metabolic syndrome, which is an obesogenic disease shown to increase risk for developing type 2 diabetes (T2DM) by five-fold (Diabetes Care, 2012). The ... -
The Physiological and Pathological Role of Mitochondrial Calcium in the Diabetic Heart
(East Carolina University, 2011)Diabetic patients are more susceptible to ischemia/reperfusion injury and cardiac dysfunction likely due alterations in mitochondrial calcium handling. The purpose of this work was to determine if redox-dependent changes ... -
Proximal vs. Distal Fascicle Behavior within the Biceps Femoris Long Head at Different Muscle Activation Levels
(East Carolina University, 2013)Hamstring strains have been shown to occur more often in the long head of the biceps femoris (BFLH) than the semitendinosus and semimembranosus, with most injuries occurring in the proximal half of the BFLH. Muscle modeling ... -
Pulmonary Pathologies Following Inhalation of Multi-Walled Carbon Nanotubes at Occupational Levels
(East Carolina University, 1/13/16)Multi-walled carbon nanotubes (MWCNT) are a nanomaterial that is growing in use and popularity. The health effects of occupational pulmonary exposure to MWCNT are currently unknown. The goals of this study were to build a ... -
