Investigations Into The Effects Of Water Exchange And The Structure Of Lanthanide Chelates, Katherine Marie Payne
Investigations Into The Effects Of Water Exchange And The Structure Of Lanthanide Chelates, Katherine Marie Payne
Dissertations and Theses
Lanthanide chelates are effective agents for improving contrast in MR images. Optimizing the relaxation of inner sphere water molecules is a common focus of research in this field. However, the efforts to design an optimal contrast agent have commonly over-looked the relationship of water position and water exchange kinetics. This work explores structural conformation, the impact of very fast water exchange kinetics on hydration, and differing tumbling rates for regioisomers of a number of lanthanide chelates. We have grown crystals of LnDOTMA and obtained structural data by X-ray diffraction that provide a picture of the chelate during water exchange and …

Vibrational spectroscopic techniques can detect small variations in molecular content, linked with disease, showing promise for screening and early diagnosis. Biological fluids, particularly blood serum, are potentially valuable for diagnosis purposes. The so-called Low Molecular Weight Fraction (LMWF) contains the associated peptidome and metabolome and has been identified as potentially the most relevant molecular population for disease-associated biomarker research. Although vibrational spectroscopy can deliver a specific chemical fingerprint of the samples, the High Molecular Weight Fraction (HMWF), composed of the most abundant serum proteins, strongly dominates the response and ultimately makes the detection of minor spectral variations a challenging task. …

Microdialysis Studies Using Porcine Pancreatic Elastase To Guide Mathematical Modeling Of Microdialysis Sampling For In Vivo Measurements., Mason W. Young
Biomedical Engineering Undergraduate Honors Theses
Microdialysis sampling uses a semi-permeable membrane to allow solute collection by diffusion. When used in conjunction with other instruments, analytes in question can be quantified. Matrix Metalloproteinases (MMPs) are enzymes involved in numerous biological processes where they serve the role of degrading extracellular matrix. Microdialysis sampling, in coordination with further analysis methods, can be used in order to measure the activity of these enzymes in a region of the body instantaneously. The intention of this project is to determine ways of measuring in vitro activity of elastase from porcine pancreas using determined activity values and the collection of elastase products. …
