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...

Time-of-flight scattering and recoil spectrometry (TOF-SARS) applied to molecular liquid surfaces : a new approach to surface composition and orientation

Creator:: Gannon, Thomas J.
Abstract:: In spite of their importance in many systems, liquid surfaces have been explored at the microscopic level to a much lesser extent than solids. Most surface analysis must take place in vacuum, a major drawback for liquids. The technique of time-of-flight scattering and recoil spectrometry (TOF-SARS) has been applied to...

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...

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...

Development of fragmentation techniques in mass spectrometry for biological applications

Creator:: Ji, Hong
Abstract:: In this dissertation, I present the work of developing more efficient and economical techniques for fragmenting large bio-molecules, and ultimately making mass spectrometry a more powerful tool in proteomics, DNA sequencing, and other areas of biomolecular analysis. Aiming at lowering the installation and operating cost, and delivering electron capture dissociation...
