Development Of Molecular Diagnostic Tools For Mycobacterium Species, Hillary Bengtson
Development Of Molecular Diagnostic Tools For Mycobacterium Species, Hillary Bengtson
Electronic Theses and Dissertations
This dissertation focuses on the development of diagnostic tools for mycobacteria using hybridization based technologies including binary deoxyribozyme (BiDz) sensors and microarrays. The genus Mycobacterium, is a diverse group of bacteria containing 150+ species including M. tuberculosis (M.tb) and non-tuberculous mycobacteria (NTM) which exhibit a range of pathogenicity, drug susceptibility and growth characteristics. M. tuberculosis (M.tb) is the causative agent of tuberculosis (TB) and the leading cause of infectious disease related deaths worldwide. The control of TB is limited by the lack of sensitive and specific diagnostic tools available at the point of care (POC). The studies presented here illustrate …
Alpha-Synuclein: Insight Into The Hallmark Of Parkinson's Disease As A Target For Quantitative Molecular Diagnostics And Therapeutics, Baggio A. Evangelista
Alpha-Synuclein: Insight Into The Hallmark Of Parkinson's Disease As A Target For Quantitative Molecular Diagnostics And Therapeutics, Baggio A. Evangelista
Honors Undergraduate Theses
Parkinson’s disease (PD) is the second-most common neurodegenerative disease after Alzheimer’s disease. With 500,000 individuals currently living with Parkinson’s and nearly 60,000 new cases diagnosed each year, this disease causes significant financial burden on the healthcare system - amassing to annual expenditures totaling 200 billion dollars; predicted to increase through 2050. The disease phenotype is characterized by a combination of a resting tremor, bradykinesia, muscular rigidity, and depression due to dopaminergic neuronal death in the midbrain. The cause of the neurotoxicity has been largely discussed, with strong evidence suggesting that the protein, alpha-Synuclein, is a key factor. Under native conditions, …
Characterizing The Function Of The N-Terminal Domain Of Omi/Htra2, Christine Nguyen
Characterizing The Function Of The N-Terminal Domain Of Omi/Htra2, Christine Nguyen
Honors Undergraduate Theses
The yeast two-hybrid system was used to isolate and characterize protein interactors of the N-terminal domain of the serine protease Omi/HtrA2 (high temperature requirement protein A2) encompassing amino acids 31-133. This large domain of Omi/HtrA2 is usually cleaved and removed through autoproteolysis to produce the mature form of the protein. Whether the N-terminal domain has any function after its removal is unknown. Omi/HtrA2 is involved in a variety of diseases including cancers, neurodegenerative disorders, and metabolic disorders, but thus far, it is assumed that its normal function is the degradation of specific substrates. To characterize any potential function of Omi/HtrA2’s …
Micro-Spectroscopy Of Bio-Assemblies At The Single Cell Level, Jeslin Kera
Micro-Spectroscopy Of Bio-Assemblies At The Single Cell Level, Jeslin Kera
Honors Undergraduate Theses
In this thesis, we investigate biological molecules on a micron scale in the ultraviolet spectral region through the non-destructive confocal absorption microscopy. The setup involves a combination of confocal microscope with a UV light excitation beam to measure the optical absorption spectra with spatial resolution of 1.4 μm in the lateral and 3.6 μm in the axial direction. Confocal absorption microscopy has the benefits of requiring no labels and only low light intensity for excitation while providing a strong signal from the contrast generated by the attenuation of propagating light due to absorption. This enables spatially resolved measurements of single …
