Development and broad application of a mass spectrometry based metabolomics platform

Creator:: Kirkwood, Jay Steven
Abstract:: Metabolomics is a comprehensive analysis of small molecules, or metabolites, in a system. Metabolomics is a hypothesis-generating experiment and offers an unbiased analysis of cell metabolism that can aid in the understanding of fundamental biological processes. Metabolomics is widely and broadly applicable in the biological sciences and has been used...

The identification and quantitation of complex polycyclic aromatic hydrocarbon mixtures in environmental samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry

Creator:: Manzano, Carlos A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants and are mostly products of the incomplete combustion of organic material. PAHs are often found in environmental samples as a complex mixture of isomers. In addition, the same sources that produce complex PAH mixtures also produce other poorly characterized mixtures of organic compounds,...

Surface composition and orientation of room temperature ionic liquids

Creator:: Law, George
Abstract:: In this thesis, we investigated the surface composition and orientation of both pure room-temperature ionic liquids (Ils) and binary mixtures of the ILs of the type consisting of the 1-alkyl-3-methylimidazolium ([C[subscropt n]mim]⁺, n=4, 8, and 12) cation coupled with either [PF₆]⁻, [BF₄]⁻, [Cl]⁻, or [Br]⁻. The surfaces of the ILs...

Mass-Spectrometric Methods for OxPTM Characterization and Quantitative Proteomics of Oxidative Stress Response

Creator:: Huang, Lin
Abstract:: Oxidative stress is deﬁned as an imbalance that favors the production of reactive oxygen species (ROS) over an organism's antioxidant defense. ROS have the ability to damage, either directly or indirectly, biomolecules including DNA, proteins, carbohydrates, and lipids. Various pathological conditions and environmental and chronic diseases have been associated with...

Chemical labeling methods and mass spectrometry of mitochondrial thiol proteomes

Creator:: Wang, Jing
Abstract:: Dysfunction of mitochondria has been linked to aging and the pathogenesis of many degenerative diseases. Aside from their primary function in energy production, mitochondria are considered as a major source and target of reactive oxygen and nitrogen species (ROS/RNS) in cells as well. The mitochondrial thiol proteome is a subset...

Gas-phase fragmentation chemistry of protonated peptide ions

Creator:: Bythell, Benjamin James
Abstract:: The fragmentation characteristics of protonated peptides have been investigated using tandem mass spectrometry (MS/MS) under various fragmentation regimes and detailed density functional theory (DFT) reaction pathway calculations. The DFT calculations predict novel salt-bridge stabilized transition structures as well as consecutive reactions occurring in proton-bound dimers for some of the ions...

Hydrogen/deuterium exchange mass spectrometry as a technology platform for studying conformational dynamics in large protein complexes

Creator:: Nirudodhi, Sasidhar N.
Abstract:: Proteins are essential to all biological systems. Proteins participate in numerous cellular processes by interacting with other proteins, other metabolites and membranes in a dynamic environment. Studying the structural and conformational properties of proteins in the solution phase is necessary to understand their protein folding and interaction dynamics. This research...

Mass-spectrometric Methods for Quantitative Proteomics and Post-translational Modification Mapping

Creator:: Motorykin, Ievgen
Abstract:: Signal transduction within and between cells is at the core of biological activity in all living systems. Signaling networks are required for regulating biological functions, including growth, development and survival. Deregulation of signaling cascades has been linked to chronic and acute diseases and disorders This thesis focuses on mass spectrometry...

Tandem mass spectrometric analysis of protein and peptide adducts of lipid peroxidation-derived aldehydes

Creator:: Wu, Jianyong
Abstract:: The adduction of proteins and other biomolecules by electrophilic lipid peroxidation products such as 4-hydroxy-2-nonenal (HNE), 4-oxo-2-nonenal (ONE), malondialdehyde (MDA) or acrolein (ACR) is thought to be an initiating and/or propagating factor in the pathophysiology of several diseases such as atherosclerosis, diabetes, Alzheimer's, Parkinson's and other age-related disorders. The identification...

Translational Studies of the High Molecular Weight Polycyclic Aromatic Hydrocarbon, Dibenzo[ def,p] Chrysene; Carcinogenesis and Metabolism

Creator:: Madeen, Erin
Abstract:: The objective of this work is to add to the body of translational data between high dose animal model research and the environmentally relevant human metabolism of the persistent pollutant dibenzo[def,p]chrysene (DBC). We furthered the knowledge of gene/exposure interactions by determining the carcinogenesis risk based on Cyp1b1 genotype following in...
