Description
Influenza is a deadly disease for which effective vaccines are sorely lacking. This is largely due to the phenomena of antigenic shift and drift in the influenza virus's surface proteins, hemagglutinin (HA) and neuraminidase (NA). The ectodomain of the matrix 2 protein (M2e) of influenza A, however, has demonstrated high levels of conservation. On its own it is poorly immunogenic and offers little protection against influenza infections, but by combining it with a potent adjuvant, this limitation may be overcome. Recombinant immune complexes, or antigens fused to antibodies that have been engineered to form incredibly immunogenic complexes with one another, were previously shown to be useful, immunogenic platforms for the presentation of various antigens and could provide the boost in immunogenicity that M2e needs to become a powerful universal influenza A vaccine. In this thesis, genetic constructs containing geminiviral replication proteins and coding for a consensus sequence of dimeric M2e fused to antibodies featuring complimentary epitopes and epitope tags were generated and used to transform Agrobacterium tumefaciens. The transformed bacteria was then used to cause Nicotiana benthamiana to transiently express M2e-RICs at very high levels, with enough RICs being gathered to evaluate their potency in future mouse trials. Future directions and areas for further research are discussed.

Telemedicine is a multipurpose tool that allows medical professionals to use technology as a means to evaluate, diagnose, and treat patients remotely. This paper focuses on the challenges that developing telemedicine programs face, specifically discussing target population, user experience, and physician adoption. Various users of telemedicine share their experiences overcoming such challenges with the greater goal of this paper being to facilitate the growth of telemedicine programs.

Description
While the transition from sectarian to allopathic medicine was almost entirely beneficial due to our perceived value in the type of evidence and transparency that science provides, key values within sectarian practice were lost in this transition. Attention to these values helps us better understand the role and treatment of patients in modern medicine. Modern scientific physicians have proven the inefficacy of sectarian treatments by scientific practices, but the efficacy of exact sectarian remedies may not have bearing on the importance of sectarian values. These values were: medical simplicity, harmlessness in treatment, independence from physicians and accessibility of treatment. A more in-depth analysis of sectarian values allows us to understand that while the values of allopathic medicine have become ubiquitous, it has not always been that way. It is time to consider the validity in the sectarian values we have abandoned; this analysis was one of many on medicine's imminent developmental horizon. This realization allows us to call into question the importance of our current practicing values, and the necessity that they continue to stand alone.

Description
This study was conducted as part of an underlying initiative to elucidate the mechanism of action of natural antibacterial clay minerals for application as therapeutic agents for difficult-to-treat infections such as methicillin-resistant Staphylococcus aureus (MRSA)-derived skin lesions and Buruli ulcer. The goal of this investigation was to determine whether exposure to the leachate of an antibacterial clay mineral, designated as CB, produced DNA double-strand breaks (DSBs) in Escherichia coli. A neutral comet assay for bacterial cells was adapted to assess DSB levels upon exposure to soluble antimicrobial compounds. Challenges involved with the adaptation process included comet visualization and data collection. To appropriately account for antimicrobial-mediated strand fragmentation, suitable control reactions comprised of exposures to water, ethanol, kanamycin, and bleomycin were developed and optimized for the assay. Bacterial exposure to CB resulted in significantly longer comet lengths compared to negative control exposures, suggesting that CB killing activity involves the induction of DNA DSBs. The results of this investigation further characterize the antimicrobial mechanisms associated with a particular clay mineral mixture. The adapted comet assay protocol described herein functions as an effective tool to assess double-strand fragmentation resulting from exposure to soluble antimicrobial compounds and to visually compare results from experimental and control reactions.

Description
Glioblastoma multiforme (GBMs) is the most prevalent brain tumor type and causes approximately 40% of all non-metastic primary tumors in adult patients [1]. GBMs are malignant, grade-4 brain tumors, the most aggressive classication as established by the World Health Organization and are marked by their low survival rate; the median survival time is only twelve months from initial diagnosis: Patients who live more than three years are considered long-term survivors [2]. GBMs are highly invasive and their diffusive growth pattern makes it impossible to remove the tumors by surgery alone [3]. The purpose of this paper is to use individual patient data to parameterize a model of GBMs that allows for data on tumor growth and development to be captured on a clinically relevant time scale. Such an endeavor is the rst step to a clinically applicable predictions of GBMs. Previous research has yielded models that adequately represent the development of GBMs, but they have not attempted to follow specic patient cases through the entire tumor process. Using the model utilized by Kostelich et al. [4], I will attempt to redress this deciency. In doing so, I will improve upon a family of models that can be used to approximate the time of development and/or structure evolution in GBMs. The eventual goal is to incorporate Magnetic Resonance Imaging (MRI) data into a parameterized model of GBMs in such a way that it can be used clinically to predict tumor growth and behavior. Furthermore, I hope to come to a denitive conclusion as to the accuracy of the Koteslich et al. model throughout the development of GBMs tumors.

Description
From 2019, a severe acute respiratory coronavirus 2, SARS-CoV-2, began to be a global pandemic. Many high income countries developed different strategies in response. This analysis intends to highlight how the COVID-19 became a global pandemic and the strategies that account for successes and failures. In identifying key policy differences, the high income countries of the United States, New Zealand and France were examined. The analysis found that New Zealand had proactive elimination strategies that proved highly effective, whereas the United States and France both struggled with mitigation factors that resulted in disproportionately higher confirmed cases and mortality rates. The analysis highlights how the airborne virus became a pandemic and then followed public policies’ effectiveness in terms of existing political institutions,and then their ability to be successful in preventing the spread of the virus.

Description
Homeless populations are often disproportionately impacted by several diseases due to factors such as overcrowding, unsanitary conditions, lack of access to healthcare and most importantly lack of education. The purpose of this project was to decrease a part of this health gap by spreading awareness of certain illnesses impacting Arizona’s homeless population and to increase the use plausible prevention methods. This was done through the creation of three simplified brochures that contained information regarding influenza, hepatitis, and schizophrenia. Two surveys were distributed to a local homeless population; the first survey was given prior to handing out the brochures and the second survey was given a week later after the participants had some time to read the information from the brochures. The data from the surveys supported the goal of the project by showing an increase in overall awareness of the diseases as well as an increase in behavioral changes that would lead to the increase of plausible prevention methods.
