The nineteenth-century invention of smallpox vaccination in Great Britain has been well studied for its significance in the history of medicine as well as the ways in which it exposes Victorian anxieties regarding British nationalism, rural and urban class struggles, the behaviors of women, and animal contamination. Yet inoculation against smallpox by variolation, vaccination’s predecessor and a well-established Chinese medical technique that was spread from east to west to Great Britain, remains largely understudied in modern scholarly literature. In the early 1700s, Lady Mary Wortley Montagu, credited with bringing smallpox variolation to Great Britain, wrote first about the practice in the Turkish city of Adrianople and describes variolation as a “useful invention,” yet laments that, unlike the Turkish women who variolate only those in their “small neighborhoods,” British doctors would be able to “destroy this [disease] swiftly” worldwide should they adopt variolation. Examined through the lens of Edward Said’s Orientalism, techno-Orientalism, and medical Orientalism and contextualized by a comparison to British attitudes toward nineteenth century vaccination, eighteenth century smallpox variolation’s introduction to Britain from the non-British “Orient” represents an instance of reversed Orientalism, in which a technologically deficient British “Occident” must “Orientalize” itself to import the superior medical technology of variolation into Britain. In a scramble to retain technological superiority over the Chinese Orient, Britain manufactures a sense of total difference between an imagined British version of variolation and a real, non-British version of variolation. This imagination of total difference is maintained through characterizations of the non-British variolation as ancient, unsafe, and practiced by illegitimate practitioners, while the imagined British variolation is characterized as safe, heroic, and practiced by legitimate British medical doctors. The Occident’s instance of medical technological inferiority brought about by the importation of variolation from the Orient, which I propose represents an eighteenth-century instance of what I call medical techno-Orientalism, represents an expression of British anxiety over a medical technologically superior Orient—anxieties which express themselves as retaliatory attacks on the Orient and variolation as it is practiced in the Orient—and as an expression of British desire to maintain medical technological superiority over the Orient.

The goal of this project was to design and create a genetic construct that would allow for <br/>tumor growth to be induced in the center of the wing imaginal disc of Drosophila larvae, the <br/>R85E08 domain, using a heat shock. The resulting transgene would be combined with other <br/>transgenes in a single fly that would allow for simultaneous expression of the oncogene and, in <br/>the surrounding cells, other genes of interest. This system would help establish Drosophila as a <br/>more versatile and reliable model organism for cancer research. Furthermore, pilot studies were <br/>performed, using elements of the final proposed system, to determine if tumor growth is possible <br/>in the center of the disc, which oncogene produces the best results, and if oncogene expression <br/>induced later in development causes tumor growth. Three different candidate genes were <br/>investigated: RasV12, PvrACT, and Avli.

Microfluidic devices represent a growing technology in the world of analytical chemistry. Serial femtosecond crystallography (SFX) utilizes microfluidic devices to generate droplets of an aqueous buffer containing protein crystals, which are then fired out as a jet in the beam of an X-ray free electron laser (XFEL). A crucial part of the device is its method of droplet detection. This project presents a design for a capacitive sensor that uses a unique electrode configuration to detect the difference in capacitance between the aqueous and oil phases. This design was developed using MATLAB and COMSOL Multiphysics simulations and printed using high-resolution 3D printing. Results show that this design can successfully distinguish between the two immiscible liquids, confirming it as a possible detection method in future SFX experiments.

During the COVID-19 pandemic, increased burdens have been placed on the Arizona healthcare system, and its healthcare providers. Using a survey with a sample of N=308 prescribing providers and nurses in the Arizona healthcare system, the impact of COVID-19 on the wellbeing of healthcare providers was assessed. The survey used measures to evaluate for physical and emotional wellbeing, burnout, stressors associated with COVID-19, and work-life experiences, and found an overall negative impact on the wellbeing of healthcare workers during the COVID-19 pandemic with increased levels of reported stress and tiredness, concern for the health of family and loved ones, concern for the hardships of patients, lack of alignment between organizational priorities and personal values, and low levels of support and appreciation from socially and from leadership at work.

The colossal global counterfeit market and advances in cryptography including quantum computing supremacy have led the drive for a class of anti-counterfeit tags that are physically unclonable. Dendrites, previously considered an undesirable side effect of battery operation, have promise as an extremely versatile version of such tags, with their fundamental nature ensuring that no two dendrites are alike and that they can be read at multiple magnification scales. In this work, we first pursue a simulation for electrochemical dendrites that elucidates fundamental information about their growth mechanism. We then translate these results into physical dendrites and demonstrate methods of producing a hash from these dendrites that is damage-tolerant for real-world verification. Finally, we explore theoretical curiosities that arise from the fractal nature of dendrites. We find that uniquely ramified dendrites, which rely on lower ion mobility and conductive deposition, are particularly amenable to wavelet hashing, and demonstrate that these dendrites have strong commercial potential for securing supply chains at the highest level while maintaining a low price point.

Fluoroquinolone antibiotics have been known to cause severe, multisystem adverse side effects, termed fluoroquinolone toxicity (FQT). This toxicity syndrome can present with adverse effects that vary from individual to individual, including effects on the musculoskeletal and nervous systems, among others. The mechanism behind FQT in mammals is not known, although various possibilities have been investigated. Among the hypothesized FQT mechanisms, those that could potentially explain multisystem toxicity include off-target mammalian topoisomerase interactions, increased production of reactive oxygen species, oxidative stress, and oxidative damage, as well as metal chelating properties of FQs. This review presents relevant information on fluoroquinolone antibiotics and FQT and explores the mechanisms that have been proposed. A fluoroquinolone-induced increase in reactive oxygen species and subsequent oxidative stress and damage presents the strongest evidence to explain this multisystem toxicity syndrome. Understanding the mechanism of FQT in mammals is important to aid in the prevention and treatment of this condition.

A growing body of research suggests a link between adverse childhood experiences and negative health outcomes. However, less is known about where racial discrimination ranks compared to other adverse childhood experiences, such as maltreatment. To address this issue, I conducted two systematic reviews of meta-analyses to compare the magnitudes of the links between racial discrimination and depressive symptoms and childhood maltreatment and depressive symptoms. My aim was to establish if racial discrimination should be considered an adverse childhood experience. My results demonstrated that the link between racial discrimination and depressive symptoms (r = 0.27) is comparable to the links between 4 different manifestations of maltreatment and depressive symptoms (physical abuse: r = 0.257, emotional abuse: r = 0.301, neglect: r = 0.381, sexual abuse: r = 0.408). I discuss the implications of these findings and propose future research directions.

The COVID-19 pandemic has resulted in preventative measures and has led to extensive changes in lifestyle for the vast majority of the American population. As the pandemic progresses, a growing amount of evidence shows that minority groups, such as the Deaf community, are often disproportionately and uniquely affected. Deaf people are directly affected in their ability to personally socialize and continue with daily routines. More specifically, this can constitute their ability to meet new people, connect with friends/family, and to perform in their work or learning environment. It also may result in further mental health changes and an increased reliance on technology. The impact of COVID-19 on the Deaf community in clinical settings must also be considered. This includes changes in policies for in-person interpreters and a rise in telehealth. Often, these effects can be representative of the pre-existing low health literacy, frequency of miscommunication, poor treatment, and the inconvenience felt by Deaf people when trying to access healthcare. Ultimately, these effects on the Deaf community must be taken into account when attempting to create a full picture of the societal shift caused by COVID-19.

Lyme disease is a common tick-borne illness caused by the Gram-negative bacterium Borrelia burgdorferi. An outer membrane protein of Borrelia burgdorferi, P66, has been suggested as a possible target for Lyme disease treatments. However, a lack of structural information available for P66 has hindered attempts to design medications to target the protein. Therefore, this study attempted to find methods for expressing and purifying P66 in quantities that can be used for structural studies. It was found that by using the PelB signal sequence, His-tagged P66 could be directed to the outer membrane of Escherichia coli, as confirmed by an anti-His Western blot. Further attempts to optimize P66 expression in the outer membrane were made, pending verification via Western blotting. The ability to direct P66 to the outer membrane using the PelB signal sequence is a promising first step in determining the overall structure of P66, but further work is needed before P66 is ready for large-scale purification for structural studies.
