The Development of a Plant-Expressed M2e-Based Universal Influenza Vaccine

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).

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.

The purpose of our study was to evaluate whether viewing videos of dogs had an effect on the stress response of college students. While there is strong support in the literature for demonstrating the beneficial effect of human-canine interactions on human stress indicators, there is very little to no literature on whether or not this phenomenon translates across a digital medium. We hypothesized that when exposed to a video of golden retriever puppies after a stress-inducing task, an individual would experience an increase in blood pressure recovery rate and a decline in perceived stress. In order to study this, we put together several surveys to test our participants' perceived stress, and we measured blood pressure several times in order to obtain a physiological measure of stress. Additionally, in order to produce a guaranteed stress response in our participants, we gave them 2 minutes to prepare a 4 minute video-recorded speech that they were not made aware of prior to entering the testing facility. After the speech task, the experimental group quietly viewed a pleasant 4 minute video containing imagery of dogs, while the control group sat silently for the same duration of time. During this time, the control group was asked to mentally review their performance and to focus intently on the feelings they experienced while giving their speech. Through these measures we found a significant recovery rate in systolic blood pressure and a trending difference between groups for the decline in negative affect. The data demonstrated that the experimental group had blood pressure levels that were significantly closer to their baseline levels when compared to the control group, whose blood pressure did not decline at the same rate. Additionally, the experimental group experienced a higher level of change in negative affect when asked to self-report their level of stress before the speech task and after the conditional recovery period. Interestingly, these findings can be applied to recent literature suggesting that systolic blood pressure is the most important factor of cardiac health to consider when assessing an individual for risk of heart disease or cardiac arrest. While the sample size of this study was small, the significant reduction in systolic blood pressure within the experimental group could indicate the possible efficacy of utilizing digital media containing imagery of canines as a form of therapy for systolically-hypertensive individuals as a means of managing their condition.

As a biology major, many of my classes have included studying the fundamentals of genetics or investigating the way genetics influence heritability of certain diseases. When I began taking upper-division psychology courses, the genetic factors of psychological disorders became an important part of the material. I was exposed to a new idea: that genes were equally important in studying somatic diseases as they were to psychological disorders. As important as genetics are to psychology, they are not part of the required courses for the major; I found many of my peers in psychology courses did not have a grasp on genetic fundamentals in the same way biology majors did. This was a disconnect that I also found in my own life outside the classroom. Growing up, my mother consistently reminded me to limit my carbs and watch my sugars. Diabetes was very prevalent in my family and I was also at risk. I was repeatedly reminded of my own genes and the risk I faced in having this biological disorder. However, my friend whose father was an alcoholic did not warn her in the same way. While she did know of her father's history, she was not warned of the potential for her to become an alcoholic. While my behavior was altered due to my mother's warning and my own knowledge of the genetic risk of diabetes, I wondered if other people at genetic risk of psychological disorders also altered their behavior. Through my thesis, I hope to answer if students have the same perceived genetic knowledge of psychological diseases as they do for biological ones. In my experience, it is not as well known that psychological disorders have genetic factors. For example, alcohol is commonly used by college students. Alcohol use disorder is present in 16.2% of college aged students and "40-60% of the variance of risk explained by genetic influences." (DSM V, 2013) Compare this to diabetes that has "several common genetic variants that account for about 10% of the total genetic effects," but is much more openly discussed even though it is less genetically linked. (McVay, 2015)This stems from the stigma/taboo surrounding many psychological disorders. If students do know that psychological disorder are genetically influenced, I expect their knowledge to be skewed or inaccurate. As part of a survey, I hope to see how strong they believe the genetic risk of certain diseases are as well as where they gained this knowledge. I hypothesize that only students with a background in psychology will be able to correctly assign the genetic risk of the four presented diseases. Completing this thesis will require in-depth study of the genetic factors, an understanding of the way each disease is perceived and understood by the general population, and a statistical analysis of the survey responses. If the survey data turns out as I expect where students do not have a strong grasp of diseases that could potentially influence their own health, I hope to find a way to educate students on biological and psychological diseases, their genetic risk, and how to speak openly about them.

Recent work in free-recall tasks suggest that human memory foraging may follow a Lévy flight distribution – a random walk procedure that is common in other activities of cognitive agents, such as animal and human food foraging. This study attempts to draw parallels between memory search and physical search, with the assumption that humans follow similar search patterns in both. To date, research merely equates the two processes (foraging in memory and the physical world) based on a similarity in statistical structure. This study starts with demonstrating a relationship between physical distance traveled and IRIs by having participants list countries. An IRI, inter-retrieval interval, is the time interval between items recalled. The next experiment uses multidimensional scaling (MDS) to derive a Euclidean perceptual space from similarity ratings of freely-recalled items and then maps the trajectory of human thought through this perceptual space. This trajectory can offer a much more compelling comparison to physical foraging behavior. Finally, a possible correlate of Lévy flight foraging is explored called critical slowing down. Statistically significant evidence was found in all three experiments. The discussion connects all three experiments and what their results mean for human memory foraging.

The college textbook is the most commonly required component of almost any college course, regardless of a student's academic discipline. Professors often expect students to have access to the textbook and to use it to complete assigned readings. Textbooks often contain features that are designed to facilitate active reading, or critical engagement with the information being read, to enhance learning of the material. However, students often do not read or prioritize reading the textbook. Students who do read, tend not to read the textbook as intended or use many of the features designed to promote active reading and enhanced learning of the material. Educational studies of textbooks tend to focus on aspects related to topics more relevant to publishers or professors with less research on aspects of the textbook applicable to students at the college level. The purpose of this study is to evaluate students' textbook use and their attitudes toward the textbook in an introductory biology course. Results of this study indicate students hold positive attitudes toward their textbook in an introductory biology course and majority of students do not use components meant to facilitate active learning. Although students report completing assigned readings, students may actually be reading select portions of what is assigned in using the textbook to prepare for exams. These results suggest that students may only be using their textbook to enhance their understanding of materials they expect to be tested on. The findings of this study help to understand the role of the textbook from the perspective of the student and provide insight for improving textbook design and use in science courses at the college level.

There is a widespread inequality in health care access and insured rates suffered by the Latino, Spanish-speaking population in Arizona, resulting in poor health measures and economic burden. The passage of the Affordable Care Act in 2010 provided mechanisms to alleviate this disparity, however, many Latino communities lack accessible information and means to gain access to health insurance enrollment. Chicanos Por La Causa (CPLC) is a community based organizing that provides many services to low-income communities across Arizona, one of which is the CPLC Insurance Program. In collaboration with the Community Action Research Experiences (CARE) at Arizona State University, the program was studied to help address the need of a LOGIC model and evaluation plan to determine its effectiveness. Interviews with three executives within CPLC were conducted in conjunction with a literature review to determine the inputs, strategies, outputs, and outcomes of the LOGIC model that drive CPLC Insurance's mission. Evaluation measures were then created to provide the necessary quantitative data that can best show to what degree the program is achieving its goals. Specifically, the results indicated the key outcomes that drive the LOGIC model, and an evaluation plan designed to provide indicators of these outcomes was produced. The implications of this study are that the suggested data collection can verify how effectively the program's actions are creating positive change, as well as show where further improvements may be necessary to maximize effectiveness.

The bull shark, Carcharhinus leucas, is a large species that it is commonly distributed worldwide in tropical and subtropical waters. Despite the bull sharks global distribution, little is known about its life history. In particular, the limited reproductive information suggests the bull shark is placental viviparous, assumed to have a biennial cycle, and that newborn pup nurseries are near the coast. In order to conserve and protect any species, an understanding of the habitats where reproductive events occur is needed. In order to better understand the habitat use in Biscayne bay, Fla, and whether certain areas are critical during the reproductive cycle of bull sharks, I will evaluate circulating levels of the hormones progesterone, estradiol, and testosterone using radioimmunoassay. These samples were collected by the University of Miami opportunistically between 2012-2020 shipped to Arizona State University, where they were analyzed. For my study a total of 73 mature samples, 27 females and 46 males, were collected over the sampling period. The results indicated that Biscayne bay is an important gestation area for bull sharks. The hormonal trends for males and females demonstrated an interesting reproductive cycle, which were further supported through other placental viviparous reproductive patterns. Females had a low level of estradiol throughout most of the year, besides in the summer where there were no sharks in the bay due to movement to estuaries. During their return to the bay, there was a peak in progesterone indicating early pregnancy. Male testosterone levels indicated that there was a production in sperm right before females speculated peak in estradiol.

Activist burnout theory has produced minimal but meaningful literature and research that explores the dynamics of burnout culture, movement in-fighting, marginalized identities, and dimensions of burnout symptoms. Black feminist visionaries and writers such as Audre Lorde and bell hooks have developed theories of love, self-care and community as central to resistance that have informed my research approach. Thus, my study aims to investigate activist burnout from a perspective that marries popular activist burnout theory with these frameworks of self-care and community. I conducted a survey of Arizona State University student organizers and activists (N=34) to address the following research questions: What are the causes and symptoms of burnout for Arizona State University activists and organizers? How have self-care and community played a role in their work and countered burnout? Can working conceptions of self-care and community serve as resistance in ways that feel meaningful to activists? The survey was broken into three dimensions: “Demographics and Experience,” “Burnout,” and “Self-Care and Community.” The results reinforced prior findings on established toxic cultures and burnout symptoms but introduced complications to working theories, such as the connections between cycles of burnout and the cyclical nature of electoral politics along with the roles of chronic and mental illness. Respondents largely demonstrated conceptions of self-care and community as resistance but also demonstrated personal and professional barriers to putting these conceptions into practice.
