Investigating the bifunctional chelate approach for radiopharmaceutical development
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Radiopharmaceuticals are drugs that contain a radioactive atom for the purpose of imaging or therapy of disease. The type of emission determines the applicability for each drug...
Ligands for the sigma receptor and the mu-opioid receptor
(University of Missouri--Columbia, 2007)
The sigma receptor is a unique receptor family with two subtypes: sigma-1 and sigma-2. In order to conduct structure-activity relationship studies (SAR), a series of specific 1-phenylpropyl-4-benzylpiperidine and 1-phenylpropyl-4- benzylpiperazine...
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 ...
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 ...
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 ...
Structural supramolecular constructs of spheres and tubes
(University of Missouri--Columbia, 2006)
This thesis examines four different molecular systems that are in part or substrates for larger structural motifs that resemble spheres or tubes. The first project used donut shaped cucurbituril and through functionalization ...
