Synthesis and characterization of novel phosphinimine ligand systems for potential applications in radiopharmaceuticals
(University of Missouri--Columbia, 2007)
Multidentate phosphinimine ligands, C₂₅H₄₉N₂P₂Si₂,(2) C₃₄H₃₈N₂P₂Si₂(3), and C₅₀H₆₆N₃P₃Si₃(4), were synthesized in near quantitative yields by Staudinger reaction using appropriate phosphines. Coordination chemistry of 2 ...
Molecular basis of protein tyrosine phosphatase inhibition by biologically important small molecules with relevance to cell signaling pathways
(University of Missouri--Columbia, 2009)
Protein tyrosine phosphatase 1B (PTP1B) is an abundant mammalian enzyme and well known to be as a central player in the insulin and leptin signaling pathways. Peracetic acid is a strong oxidant molecule, endogenously ...
Pertechnetate immobilization with sulfide in aqueous media under anaerobic and aerobic environments
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Technetium-99 (Tc-99) is a high yield radionuclide produced from thermal neutron fission. As a consequence of the development of nuclear weapons over the past 50 years...
Probing supramolecular assemblies via fluorescent reporter molecules
(University of Missouri--Columbia, 2007)
Supramolecular, self-assembled nanocapsules have shown the capability to encapsulate organic guests. Since most of the work was done previously in the solid state, the novelty of this research was its focus on probing ...
Determination of total selenium and seleno-amino acids in yeast and aquatic organisms by liquid chromatography and inductively coupled plasma mass spectrometry
(University of Missouri--Columbia, 2007)
The primary goal of this dissertation research was to develop methods for routine speciation analysis of selenium in tissues. A method for total selenium using on-line stable isotope dilution analysis with conventional ...
The use of pluripotent stem cells as a model for early human placentation
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Throughout gestation, the placenta plays a critical role in ensuring proper development of the fetus. The placenta functions to exchange nutrients, oxygen, and fetal waste...
Studies on radiometal chelator-bombesin peptide-based radiopharmaceuticals for tumor GRP-receptor subtype mediated radioimaging
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Bombesin-like peptides bind to gastrin-releasing peptide receptor subtype 2 (BB2) with significantly high binding affinity and specificity. In an attempt to develop non...
Radionuclide production and separation techniques for radiopharmaceutical development and nuclear waste processing
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] With increasing cancer incident rates and advancements in nuclear medicine, the demand for optimizing pathways to produce radionuclides or investigating new radionuclides...
Investigations into the chemistry of protein tyrosine phosphatase redox regulation
(University of Missouri--Columbia, 2009)
Transmission of complex intracellular signals, such as those for glucose uptake or proliferation, is often accomplished through the reversible phosphorylation of specific protein tyrosine residues. This reversible ...
Studies of natural products that reveal novel strategies for efficient modification of DNA
(University of Missouri--Columbia, 2006)
DNA is the central molecule in cells. The correct function of cells depends on the structure of DNA. DNA damaging natural products often show cytotoxic or mutagenic properties, which many times land them medicinal value ...
Spatially resolved and bulk zinc analysis in biological samples of patients at different stages of Alzheimer's disease by high resolution inductively coupled plasma mass spectrometry
(University of Missouri--Columbia, 2008)
One hypothesis that has gained considerable attention in the pathogenesis of Alzheimer's disease (AD) is trace element toxicity, and various elements, including zinc, have become the foci of renewed interest. The first ...
