Evaluating the suitability of the human toenail as a biomonitor for manganese status: the one source cohort
(University of Missouri--Columbia, 2007)Numerous studies have demonstrated that the human toenail is a reliable biomonitor for the intake of Se and other elements. The objective of this study was to evaluate the hypothesis that Mn intake is reflected in toenail ... -
Nitrosative guanosine deamination : pyrimidine ring opening implications of effects in homogeneous solution as well as anisotropic environments
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In recent years a great deal of interest has been focused on the exposure to nitrous acid (HNO2), nitric oxide (NO) and other nitrosating species ... -
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 ... -
pH sensitive fluorescent sensors
(University of Missouri--Columbia, 2007)Pheochromocytoma is a cancer of the adrenal gland. Pheochromoocytomas produce a variety of catecholamines, including norepinephrine. The result is high blood pressure which is caused by the release of catecholamines into ... -
Phosphinimines as potential technetium environmental sensors
(University of Missouri--Columbia, 2007)Phosphinimines, R₃P=NSiMe₃, undergo hydrolysis to form the phosphiniminiumcation, R₃P=NH₂+, which forms the ion pair [R₃P=NH₂+][X-] in the presence of an anion.Preliminary studies show that in the presence of TcO₄-, ... -
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 ... -
Structural studies of acid phosphatases from pathogenic bacteria
(University of Missouri--Columbia, 2007)Acid phosphatases are important, ubiquitous, and diverse group of enzymes that catalyze the transfer of phosphoryl from phosphomonoester to water forming inorganic phosphate and alcohol. These enzymes play critical roles ... -
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 ...
