Awareness Of Genetic Predispositions That Increase The Risk Of Breast Cancer, Carly Huber
Awareness Of Genetic Predispositions That Increase The Risk Of Breast Cancer, Carly Huber
Honors Undergraduate Theses
Breast cancer is the most commonly diagnosed cancer in women in the United States and is the leading cause of cancer-related death among women worldwide. Certain demographics, such as racial/ethnic, age, and gender groups, are underrepresented in breast cancer studies. This lack of representation results in issues with creating genetic tests, as variants associated with those groups are not being detected. Furthermore, these underrepresented demographics are receiving a worse prognosis than those that are overrepresented in research. This study aimed to understand how informed the understudied racial/ethnic, gender, and age populations are regarding breast cancer and genetic testing compared to …
Overview Of Direct Thrombin Inhibitors For Use In Staphylococcus Aereus Infections, Joseph C. Risler
Overview Of Direct Thrombin Inhibitors For Use In Staphylococcus Aereus Infections, Joseph C. Risler
Honors Undergraduate Theses
The pathogenicity and intractable nature of the microorganism Staphylococcus aureus (SA) has been long documented and highlighted by many health care agencies, with emphasis on its ability to exploit the human coagulation system to deadly effect. Two drugs from a class of inhibitors known as Direct Thrombin Inhibitors (DTI) have been shown to have a substantial effect on the enzyme secreted by SA known as Staphylocoagulase (SC), but up until now the application of this potential treatment has been limited. This paper strives to supply an overview of these clinical studies and propose a novel protocol for testing DTI's on …
Studies Of Norspermidine Uptake In Drosophila Suggest The Existence Of Multiple Polyamine Transport Pathways, Michael Dieffenbach
Studies Of Norspermidine Uptake In Drosophila Suggest The Existence Of Multiple Polyamine Transport Pathways, Michael Dieffenbach
Honors Undergraduate Theses
Polyamines are a class of essential nutrients involved in many basic cellular processes such as gene expression, cell proliferation, and apoptosis. Without polyamines, cell growth is delayed or halted. Cancerous cells require an abundance of polyamines through a combination of synthesis and transport from the extracellular environment. An FDA-approved drug, D,L-α-difluoromethylornithine (DFMO), blocks polyamine synthesis but is ineffective at inhibiting cell growth due to polyamine transport. Thus, there is a need to develop drugs that inhibit polyamine transport to use in combination with DFMO. Surprisingly, little is known about the polyamine transport system in humans and other eukaryotes. Understanding the …
An Rnai Screen To Identify Components Of A Polyamine Transport System, Adam J. Foley
An Rnai Screen To Identify Components Of A Polyamine Transport System, Adam J. Foley
Honors Undergraduate Theses
Polyamines, specifically putrescine, spermidine, and spermine, are small cationic molecules found in all organisms. Cells can biosynthetically make these molecules, or alternatively, they can be transported from the extracellular environment. Malignant cells have been shown to require relatively high amounts of polyamines. There is a chemotherapeutic agent, DFMO, used to block the biosynthesis of polyamines. Many malignant cells can circumvent DFMO therapy by activating their transport system. A potential solution is to simultaneously block biosynthesis and transport of polyamines. However, little is known about the polyamine transport system in higher eukaryotes.
This thesis aims to add to the basic biological …
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 …
