Development Of A Fluorescent Drug Screening Platform For Inhibitors Of Mycobacterium Tuberculosis Protein-Protein Interactions, Zina Versfeld Jan 2015

Development Of A Fluorescent Drug Screening Platform For Inhibitors Of Mycobacterium Tuberculosis Protein-Protein Interactions, Zina Versfeld

HIM 1990-2015

Tuberculosis (TB) is a respiratory disease caused by Mycobacterium tuberculosis (Mtb) that kills around 1.3 million people annually. Multi-drug resistant TB (MDR-TB) strains are increasingly encountered, in part resulting from shortcomings of current TB drug regimens that last between six to nine months. Patients may stop taking the antibiotics during their allotted regimen, leading to drug resistant TB strains. Novel drug screening platforms are therefore necessary to find drugs effective against MDR-TB. In order to discover compounds that target under-exploited pathways that may be essential only in vivo, the proposed screening platform will use a novel approach to drug discovery …

Environmentalism And Environmental Constitutional Ballot Initiatives In Florida: The Elements Of Support For Amendment One In 2014 In The Context Of Current Environmental Attitudes., Michael Jones

Electronic Theses and Dissertations

Americans express support for “the environment” with environmental support cutting across political and demographic differences and cleavages. In the past 15 years, however, period effects, political sorting, and the emergence of a powerful anti-environmental movement have lessened the generalized levels of environmental support. Using the 2012 CCES survey, the expressed attitudes regarding multiple environmental issues found significant differences in levels of environmental support nationally by party, Tea Party attitudes, ideology, and certain demographic characteristics. For Floridians, the differences between the most pro-environmental respondents and the most anti-environmental are narrower; partisan identification itself is not significant in environmental attitudes; but ideology, …

Influence Of Personal And State Level Variables On Perception Of State Emergency Management Network Resilience In 47 States, Victoria Jennison Jan 2015

Influence Of Personal And State Level Variables On Perception Of State Emergency Management Network Resilience In 47 States, Victoria Jennison

Electronic Theses and Dissertations

Emergency management coordination in the United States has fallen victim to over a century of strategies to organize, reorganize, consolidate, or decentralize disaster preparedness, planning and response. Regardless of the agency in charge at the federal level, individual citizens have been responsible for their own well-being immediately after any disaster or emergency event for more than 100 years because it takes time to mobilize and deliver aid. The system most often charged with managing that mobilization during an emergency event that exceeds the response capacity of local public safety agencies is the state emergency management network.

The Ct20 Peptide As An Agent For Cancer Treatment, Rania Bassiouni Jan 2015

The Ct20 Peptide As An Agent For Cancer Treatment, Rania Bassiouni

Electronic Theses and Dissertations

Due to cancer recurrence and the development of drug resistance, metastatic breast cancer is a leading cause of death in women. In the search for a new therapeutic to treat metastatic disease, we discovered CT20p, an amphipathic peptide based on the C-terminus of Bax. Due to inherent properties of its sequence and similarity to antimicrobial peptides, CT20p is a promising cytotoxic agent whose activity is distinct from the parent protein (e.g. does not cause apoptosis). CT20p is not membrane permeable but can be introduced to cells using polymeric nanoparticles, a method that promotes efficient delivery of the peptide into the …

Differential Expression Of Proteins Involved In Vldl Trafficking Causes Reduced Vldl Secretion In Male Ames Dwarf Mice, Faisal Ahmed Moinuddin Jan 2015

Differential Expression Of Proteins Involved In Vldl Trafficking Causes Reduced Vldl Secretion In Male Ames Dwarf Mice, Faisal Ahmed Moinuddin

Electronic Theses and Dissertations

Cardiovascular diseases (CVDs) have been recorded as the number one cause of death worldwide, accounting for 32% of total deaths annually. More than two-thirds of all CVD cases are associated with atherosclerosis, which is the accumulation of fats and other substances causing plaque formation in the interior walls of major arteries. This leads to narrowing of the lumen and hardening of the arteries, ultimately resulting in angina, heart attack and/or stroke. Studies have shown that the pathogenesis of atherosclerosis and associated CVDs is strongly linked to elevated secretion of liver-specific lipoproteins called very-low-density-lipoprotein (VLDL). VLDLs are crucial lipoproteins responsible for …

The Relationship Between Dna's Physical Properties And The Dna Molecule's Harmonic Signature, And Related Motion In Water--A Computational Investigation, Victor Boyer Jan 2015

The Relationship Between Dna's Physical Properties And The Dna Molecule's Harmonic Signature, And Related Motion In Water--A Computational Investigation, Victor Boyer

Electronic Theses and Dissertations

This research investigates through computational methods whether the physical properties of DNA contribute to its harmonic signature, the uniqueness of that signature if present, and motion of the DNA molecule in water. When DNA is solvated in water at normal 'room temperature', it experiences a natural vibration due to the Brownian motion of the particles in the water colliding with the DNA. The null hypothesis is that there is no evidence to suggest a relationship between DNA's motion and strand length, while the alternative hypothesis is that there is evidence to suggest a relationship between DNA's vibrational motion and strand …

The Large Ribosomal Subunit Protein L9 Enables The Growth Of Ef-P Deficient Cells And Enhances Small Subunit Maturation, Anusha Naganathan, Matthew P. Wood, Sean D. Moore

Faculty Bibliography 2010s

The loss of the large ribosomal protein L9 causes a reduction in translation fidelity by an unknown mechanism. To identify pathways affected by L9, we identified mutants of E. coli that require L9 for fitness. In a prior study, we characterized L9-dependent mutations in the essential GTPase Der (EngA). Here, we describe a second class of L9-dependent mutations that either compromise or inactivate elongation factor P (EF-P, eIF5A in eukaryotes). Without L9, Delta efp cells are practically inviable. Cell fractionation studies revealed that, in both the Der and EF-P mutant cases, L9's activity reduces immature 16S rRNA in 30S particles …

Faculty Bibliography 2010s

Stable isotope analysis is a useful tool to track animal movements in both terrestrial and marine environments. These intrinsic markers are assimilated through the diet and may exhibit spatial gradients as a result of biogeochemical processes at the base of the food web. In the marine environment, maps to predict the spatial distribution of stable isotopes are limited, and thus determining geographic origin has been reliant upon integrating satellite telemetry and stable isotope data. Migratory sea turtles regularly move between foraging and reproductive areas. Whereas most nesting populations can be easily accessed and regularly monitored, little is known about the …
