Heavy Metal Concentrations in Biofluid Samples and their Correlation to Metabolic Syndrome
(East Carolina University, 2018-05-01)The goal of this project was to determine if toxic metals such as Cr, Mn, As, Ni, Cd, and Pb are stored in the adipose tissue of farm animals, in particular swine. To detect these trace elements, a method of extraction and ... -
HOW CHARGED RESIDUES INFLUENCE THE THERMAL STABILITY OF COLLAGEN: A STUDY WITH NATURAL AND NON-NATURAL AMINO ACIDS
(East Carolina University, 2020-09-16)Triple-helical collagens are key structural proteins in mammals. Their ubiquity and diverse functions drive our interest into understanding their behavior at a fundamental level. This thesis describes a reductionist approach ... -
Identification of Damaged DNA Adducts from Exposure to Benzo[a]pyrene in the TP53 Gene
(2015)Benzo[a]pyrene is a carcinogen associated with tobacco smoke that can damage DNA after it is metabolized into highly reactive forms. Identifying the resulting DNA adducts can give greater insight into the mutations that ... -
IDENTIFICATION OF NOVEL CYTOTOXIC PROSTAGLANDIN METABOLITES PRODUCED IN ARACHIDONOYL ETHANOLAMIDE-TREATED TUMOREGENIC KERATINOCYTES
(East Carolina University, 2012)Arachidonoyl ethanolamide (AEA) induces apoptosis in mouse tumorigenic keratinocytes (JWF-2 cells). Our previous data show that AEA is metabolized by COX-2 to pro-apoptotic J-series prostaglandins. COX-2 is an enzyme that ... -
Identification of the Cu(II) Coordinating Residues in the Prion Protein by Metal-Catalyzed Oxidation Mass Spectrometry: Evidence for Multiple Isomers at Low Cu(II) Loadings
(East Carolina University, 2008-09-02)While the Cu(II) binding sites of the prion protein have been well studied under Cu-saturation conditions, the identity of the residues involved in coordinating Cu(II) at low stoichiometries and the order in which the ... -
Identifying compensatory genomic changes due to nickel (Ni2+) exposure: electrochemistry and quantifying DNA damage
(East Carolina University, 2020-11-24)Nickel is a toxic heavy metal that has been shown to cause adverse healthconditions in organisms. DNA damage has been observed in nematodes in response to nickel exposure. Nematodes originating from environments with high ... -
The implementation of a GC/MS data system using DISNET: a Distributed Instrument System NETwork
(East Carolina University, 1984)The primary goal of a computer network is to achieve resource sharing between several computers. Resource sharing is most easily performed at the application program level, with lower layers of software providing communications ... -

Improving Prostamide Anti-Cancer Activity Through Derivatization and Micellar Delivery
(East Carolina University, 2023-04-28)Colorectal cancer is the fourth most common cancer diagnosis per year as well as the fourth highest rate of death per year according to the Centers for Disease Control. Approximately 1/3rd of the diagnosed colorectal cancer ... -
Improving the Reliability of Peptide-Zinc (II) Binding Constant Determination with Mass Spectrometry
(East Carolina University, 2012)Electrospray Ionization Mass Spectrometry (ESI-MS) has become a powerful technique for analyzing protein- and peptide-ligand interactions and quantifying their binding constants (K[subscript]b). However, ESI-MS as an ... -
Insight Into the Location of DNA Xenobiotic Damage by Mass Spectrometry
(2014)Damage to DNA by a bioactivated xenobiotic typically occurs at specific sites within the genome, called hotspots. An example of this is benzo[a]-pyrene (BP), a xenobiotic that enters the body via cigarette smoking. ... -
Installation of Metal-Binding Functionality at Lysine Residues via Azide-Alkyne "Click Chemistry"
(2015-04-29)A novel non-natural amino acid designed to bind divalent metal ions, dubbed Lys(PYRIT), was prepared in a “click reaction” by treating Fmoc-Lys(N3)-OH with 2-ethynylpyridine and Cu(I). It was incorporated into a 12-residue ... -
Investigating Intra- and Inter-Molecular Coevolution of Intrinsically Disordered Protein, Prothymosin-alpha
(East Carolina University, 1/13/16)Prothymosin-α (ProTα) is a small, highly acidic protein found in the nuclei of virtually all mammalian tissues. It belongs to a class of proteins known for their lack of a rigid three-dimensional structure called intrinsically ... -
Investigation Into Intermolecular Interactions of Gd3N@C80(OH)n Using Fluorescence Spectroscopy
(2014)The aim of this experiment was to investigate the intermolecular interactions of the endohedral metallofulerene complex in water and various metal cation solutions. These interactions were observed using a methodology ... -
Investigation Into The Scope, Limitations, And Mechanistic Aspects Of A Regioselective Acylation Of Cycloplatinated Complexes
(East Carolina University, 2015)In the reaction of N-isopropyl-N-phenyl-2,2'-bipyridin-6-amine with potassium tetrachloroplatinate, the selective C-H bond activation was complicated by the low selectivity of sp² C-H bond activation in acetonitrile and ... -
Investigation of Molecular Mechanism of Transthyretin Oligomerization Associated with ATTR Amyloidosis
(East Carolina University, 2022-04-27)Transthyretin amyloidosis (ATTR) has classically been diagnosed predominantly post-observation of amyloid fibril deposition on soft tissues within the body, however, recent studies have shown that oligomers which arise ... -
Investigation of possible driving forces on counter-intuitive thermal collapse of intrinsically disordered proteins
(East Carolina University, 2016-08-18)Intrinsically disordered proteins are an emerging class of proteins that contain no secondary or tertiary structure. Through bioinformatics studies it has been predicted that a third of the human proteome consists of ... -
