AMINO ACID BINDING TO AFLATOXIN B1 DURING A NOVEL FOOD TREATMENT PROCESS PROTECTS AGAINST GENOTOXICITY
(East Carolina University, 2018-04-19)Access to clean food is a crucial factor in maintaining public health. Contamination of food supplies with toxic substances can lead to a myriad of health issues. As a mycotoxin, aflatoxin B1 (AFB1) is a naturally occurring ... -
Apigenin prevents chemically-induced skin tumor formation and inhibits COX-2 expression and activity in SKH-1 mouse epidermis
(East Carolina University, 2012)The most common type of cancer in the United States is non-melanoma skin cancer (NMSC), with an estimated two million new cases diagnosed each year. Numerous malignancies including NMSC, colon, breast, and prostate cancer ... -
Catecholamine metabolism via monoamine oxidase (MAO) within myocardium of individuals with type 2 diabetes
(East Carolina University, 2019-04-23)The primary comorbidity and cause of mortality in type 2 diabetes is cardiovascular disease. The structural and the functional cardiac remodeling observed in patients with type 2 diabetes has been shown to be driven by a ... -
Central GPR109A Mediates Neuronal Oxidative Stress and Pressor Response in Conscious Rats
(East Carolina University, 2016-05-03)The primary goal of this study was to characterize the role of GPR109A in the rostral ventrolateral medulla (RVLM) in blood pressure (BP) regulation and to elucidate the mechanisms involved in the hypertensive response ... -
Comparison of tolerance characteristics in the guinea pig following chronic in-vivo exposure to opioid versus cannabinoid receptor agonists
(East Carolina University, 2010)Few studies have compared the nature of tolerance that develops following chronic in vivo opioid treatment with that which develops after chronic cannabinoid exposure in the same tissue and species. Based on similarities ... -
Discovery and investigation of a novel role for mitochondrial prohibitin in mitigating acute heart failure in endotoxic shock
(East Carolina University, 2014)Sepsis results in more than 200,000 deaths annually and is the 10th leading cause of death in the United States (US). In spite of significant advances in medical care the mortality rate for sepsis has continued to rise. ... -
Disrupted Adiponectin-Connexin43 Signaling Underlies Exacerbated Myocardial Dysfunction in Diabetic Female Rats
(East Carolina University, 2019-04-25)The 2015 American Heart Association scientific statement has advocated for sex- specific research to understand the paradoxically higher sensitivity of women to type 2 diabetes mellitus (T2DM)-associated cardiovascular ... -
Disruption of mitochondrial fitness in human preadipocytes by fatty acids
(East Carolina University, 2013)Adipose tissue lies at the core of energy metabolism, by not only releasing and taking up fatty acids (FA) according to the individuals overall surplus or deficit of energy, but also signaling other tissues to regulate ... -
EARLY LIFE STRESS AND PHARMACEUTICAL POLLUTANTS: DEVELOPMENTAL TOXICITY OF EMERGING AQUATIC CONTAMINANTS IN A MODEL TERRESTRIAL SPECIES
(East Carolina University, 2019-07-18)Trace amounts of pharmaceutical and personal care products are plaguing water sources around the globe, and with no current regulations, these emerging contaminants pose a threat to environmental and human health. While ... -
EFFECTS OF CANNABIDIOL ON VOCAL LEARNING AND RECOVERY FROM CNS DAMAGE
(East Carolina University, 2019-06-19)Cannabidiol (CBD), a non-euphorigenic compound derived from Cannabis, shows promise for improving recovery following cerebral ischemia and was recently effective for the treatment of childhood seizures caused by Dravet and ... -
Effects of psychological stressors and [delta]⁹-THC acutely and chronically on zebra finch song behavior and dendritic spine density
(East Carolina University, 2020-06-22)This dissertation investigated song performance and dendritic spine density, following acute restraint stress in adult zebra finches and, following chronic mild stress and CB1 receptor partial agonist [delta]⁹-tetrahydrocannabinol ... -
Examining the therapeutic potential of the investigational agent, 15dPMJ2, in mismatch repair proficient colon cancer
(East Carolina University, 2022-08-15)Despite the success of immune checkpoint inhibitor (ICI) therapy in many cancers, colon cancer with low microsatellite instability (MSI-L), also known as proficient mismatch repair (pMMR), does not respond to these agents. ... -

EXPLORING DIFFERENCES IN INDIVIDUAL SUSCEPTIBILITY TO LIPOTOXICITY AND THE UNDERLYING MECHANISMS IN THE MITOCHONDRIA OF PRIMARY PREADIPOCYTES
(East Carolina University, 2018-07-17)Prolonged exposure to fatty acids (FAs), at levels normally seen during fasting, can be cytotoxic in vulnerable cells including preadipocytes. Prior work from our laboratory has shown that FAs cause mitochondrial inner ... -
Identification of Factors Associated with the Development and Decay of Heterologous Tolerance to Morphine in the Guinea Pig
(East Carolina University, 2016-05-03)It is believed that the heterologous tolerance that develops upon chronic exposure to morphine is the result of adaptive changes in the cellular signaling pathways associated with the [mu] opioid receptor. Proposed adaptive ... -
The immune and neurological impacts of developmental Bisphenol A exposure in a C57bl/6 mouse model
(East Carolina University, 2014)Environmental exposure to exogenous agents during critical time points of development may be associated with the onset of deleterious effects, including immune and neurological disorders. Numerous studies have shown that ... -
