Cancer is a continuous global health issue. It is the second leading cause of death behind heart disease. Disparities across the emergence of cancer and resulting fatalities raise the importance of researching the disease. Treatments are available for certain types of cancers. However, these are typically accompanied by residual problems including side effects and the possibility for relapse. Some treatments attack all cells, leading to unwarranted side effects that make the possibility of living a comfortable life nearly impossible. Other treatments are specific to certain genetic alterations, making them only useful for a small percentage of patients. Not one treatment …

Chagas disease (ChD) is caused by Trypanosoma cruzi (T. cruzi), an intracellular protozoan parasite. ChD has a global mortality of 15,000 annual deaths, and approximately, 8-10 million people are infected. There is growing concern in the United States as autochthonous cases of ChD have been reported in the southern region. The two available treatments are only partially effective and highly toxic. N-aroyl derivatives and α, β-unsaturated ketones have been previously tested against Leishmania, a closely related parasite, demonstrating selective toxicity towards the microorganism. The objective of this study is to evaluate a drug library consisting of 21 α, β-unsaturated ketones …
Pacific Black Duck Ecology And Habitat Assessment In Aunu'u, American Samoa, And Their Relationship To Other Mallard-Like Ducks Of Oceania, Greater Indonesia, And The Philippines, Marissa Kaminski
Open Access Theses & Dissertations
Determining a species’ ecological needs, assessing the quality of their habitat, and determining genetic differentiation and connectivity among populations is essential to their conservation. My dissertation focuses on obtaining such a holistic view for a population of Pacific Black Ducks recently established on the Island of Aunu’u, American Samoa. Specifically, I present the first evaluation of the ecology and habitat of a recently established population of Pacific Black Ducks on the Island of Aunu’u, American Samoa, in Chapter 1, while I assess the genetic connectivity and relationship of this population to other Mallard-like ducks found in Greater Indonesia, Oceania, and …
The Role Of Calcium Ions In Signaling And Regulation Of Efflux Pump Genes In Staphylococcus Aureus, Amy Rebecca Nava
The Role Of Calcium Ions In Signaling And Regulation Of Efflux Pump Genes In Staphylococcus Aureus, Amy Rebecca Nava
Open Access Theses & Dissertations
Calcium ions (Ca2+) play an important role in eukaryote cell signaling and regulation of physiological functions. Although evidence of a similar role for Ca2+ in prokaryotes has been difficult to demonstrate, there is mounting evidence that Ca2+ acts as a cell regulator in bacteria. The purpose of this study was to investigate Ca2+ signaling and the effect of Ca2+ on gene expression of various multidrug resistant (MDR) efflux pumps and their regulator MgrA in Staphylococcus aureus and clinically isolated MRSA. We hypothesized that the presence of Ca2+ increased gene expression of multidrug resistance pumps, LmrS, NorA, and the regulator, MgrA. …

Giardiasis, caused by an intestinal protozoan, Giardia lamblia, is a major public health problem worldwide. Giardia infection is spread through the fecal-oral route via contaminated water and food. It is estimated that over 280 million people are infected with Giardia across the globe. Giardia is a non-invasive parasite and consists of a two-stage life cycle: trophozoites and cysts. Ingested cysts undergo excystation in the proximal small intestine, releasing two trophozoites (excyzoites). Upon reaching the distal small intestine and colonizing there, trophozoites transform into cysts by encystation. It has been reported earlier that the process of encystation induced the synThesis of …

Androgen receptor (AR)-regulated genes contribute to the initiation and progression of prostate cancer. Receptor signaling persists and plays a pivotal role in late-stages of the disease, for which there is currently no treatment. Thus, there is a need to understand the mechanisms regulating AR function as a means to identify drug targets for potential therapeutics. The FKBP52 cochaperone has emerged in recent years as a regulator of AR activity that is functionally linked in the AR signaling pathway. FKBP52 is a known positive regulator of AR and believed to interact with AR at its binding function 3 surface (BF3), a …
