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 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. ... -
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 ... -
A Molecular Dynamics Study into Annexin A1 Induced Membrane Binding and Aggregation
(East Carolina University, 2010)Annexins constitute a family of proteins that bind to anionic membranes in a reversible and calcium dependent manner through the unique architecture of their calcium binding sites. In addition, annexins with relatively ... -
NMR Studies into the Potential Interactions of Fullerene C[subscript]60, with Tetraphenylporphyrin, H[subscript]2[TPP] and Some of its Derivatives
(East Carolina University, 2011)The curved [pi] surface of fullerene, C[subscript]60, shows a tendency to interact with other molecules, making it an interesting target for building supramolecular arrays. The interaction can be relative strong and may ... -
Oxidation of Isoprene to Methyl vinyl ketone and Methacrolein via Hydroxyl Radical : A Regenerative Mechanism for the Hydroxyl Radical
(East Carolina University, 2013)Isoprene is an important molecule in atmospheric chemistry. Belonging to a class of molecules known as volatile organic compounds, it undergoes reactions with several different oxidizers in the atmosphere, including ... -
Prothymosin-Alpha : Features of the protein sequence that contribute to the anti-HIV Activity
(East Carolina University, 2010)Prothymosin-alpha (ProT[alpha]) is a protein mainly located in the nucleus of the cells. Though its exact function is not known, it is believed to be involved in cell proliferation. The ability of this protein to inhibit ... -
Recognition of bacterial lipid headgroups by fluorescent crown ether-naphthalimides
(2015)The increasing incidence of antibiotic- resistant bacterial strains is a significant threat to human health. New antimicrobial mechanisms that feature reduced resistance potential are necessary to slow down the rapid ... -
Solvent and Solubility Effects on Quinone Ratios
(East Carolina University, 2012)Monoquinones and diquinones are a biologically and chemically important class of compounds that can be found in numerous natural products such as: thymoquinone, oosporein, coenzyme Q, embelin and the respective dimer, ... -
Solvent-Controlled Switch of Selectivity between sp[superscript]2 and s[superscript]p3 C-H Bond Activation by Platinum (II)
(East Carolina University, 2010)Cyclometalation reactions have been studied intensely for the past few decades, especially those containing palladium. The factors that control the process of the C-H bond activation, however, are not yet completely ... -
