Gle1 is an mRNP export mediator with major activity localized to the nuclear pore complex in eukaryotic cells. The protein's high preservation across vast phylogenetic distances allows us to approximate research on the properties of yeast Gle1 (yGle1) with those of human Gle1 (hGle1). Research at Vanderbilt University in 2016, which provides the research basis of this thesis, suggests that the coiled-coil domain of yGle1 is best crystallized in dicationic aqueous conditions of pH ~8.0 and 10\u201420% PEG 8000. Further exploration of crystallizable microconditions revealed a favorability toward lower pH and lower PEG concentration. Following the discovery of the protein's native crystallography conditions, a comprehensive meta-analysis of scientific literature on Gle1 was conducted on the association of Gle1 mutations with neuron disease.

The growing Hispanic population in Phoenix, Arizona frequently lacks financial resources which may limit their access to health care. The goal of this study was to identify the ideal factors in a health insurance plan for the Hispanic/Latino population in Phoenix, AZ. A survey was designed to gather information regarding demographics, health insurance, preferences, and affordability. The survey was completed by 260 participants. Several multivariate regressions were run using SAS Statistical Software. The final model generated explained 4.48% of the variation in the data set. It showed that an individual who identified as Hispanic/Latino was 8.2% less likely to have health insurance. In addition, an individual who identified as a US Citizen was 23% more likely to have health insurance. To improve access and enrollment among the Hispanic/Latino population, further investigation is needed to identify relevant communication techniques that increase enrollment among this high-risk community.

This thesis project investigated the linguistic competence of four brothers in an attempt to evaluate the effects that assimilation in the United States has on language loss within second generation speakers. The project employed the use of a case study and autoethnography in order to take a closer look at the concepts of assimilation, acculturation, and language loss, as well to provide a real world example of their interrelatedness. The second generation, or the heritage speakers in the family, were the focus of the study in order to provide a closer look at how the heritage language was retained within said generation. The project found that although there has historically been a push to assimilate immigrants into the American society, my brothers and I are not being assimilated as much as we are being acculturated. The project also found that although we grew up speaking Spanish at home, education in the language was essential in developing fluency in the subcategories of reading and writing, which are often neglected in the household.

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 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.

Language has a critical role as a social determinant of health and a source of healthcare disparities. Rhetorical devices are ubiquitous in medicine and are often used to persuade or inform care team members. Rhetorical devices help a healthcare team acknowledge and interpret narratives. For example, metaphors are frequently used as rhetorical devices by patients to describe cancer, including winning or losing a battle, surviving a fight, war, potentially implying that the patient feels helpless like a pawn fighting in a struggle directed by the physician, thus reducing patient autonomy and agency. However, this occidental approach is flawed because it excessively focuses on the individual's agency and marginalizes external factors, such as cultural beliefs and social support (Sontag, 1989). Although there is a large body of research about how the rhetoric of medicine affects patients in the United States, there is a lack of such research about how patient experiences' rhetoric can help increase the understanding of Latino populations' unique social determinants. This creative project aims to analyze the rhetorical differences in the description of disease amongst Latino and American communities, translating to creating an educational module for a Spanish for biomedical sciences class. The objective is to increase future healthcare professionals' ability to understand how the composition of descriptions and medical rhetoric in different mediums of humanities can serve as critical tools to analyze social determinants in Latino healthcare delivery.

The transcriptome of an organism is a collection of the various messenger RNAs that the genes of an organism produce. As the level of gene expression is different between different tissues of an organism, understanding the transcriptome serves as a way to better understand the differences between the functions and abilities of tissues and cells in an organism. This understanding of the transcriptome can aid further research in targeted disease treatments and indentifying new biomarkers. This study aims to gather the transcriptome from various tissues of the organism Daphnia pulex. This will be done by using a combination of single cell RNA sequencing (scRNA-seq), which involves the isolation and sequencing of single cells, and single nuclei RNA sequencing (snRNA-seq), which involves the isolation and sequencing of single nuclei. Here we show the viability of isolating single cells and single nuclei from various Daphnia pulex tissues using different techniques and enzymes including trypLE, trypsin EDTA, accutase, etc by using microscopy and automatic cell counting. The results show that each tissue is best isolated using different techniques.

Curricular Design in Languages for Specific Purposes: The Case of a Needs Analysis for the Design of a Spanish for Pharmacists Course is a thesis project that argues for the creation of a Spanish course for pharmacists based in the model of Languages for Specific Purposes courses. In order to do this, a needs analysis was conducted by surveying and interviewing a pharmacist and medical Spanish instructor. Based on these results, objectives, activities, and evaluation criteria were created for such a course. The needs analysis found that Spanish use in a pharmacy is not limited to one ability or task, but rather an integration of many such as reading, writing, listening, and speaking. This course would be an invaluable addition to pharmacy schools in the United States due to the growing Hispanic population across the country.

Immediate early genes (IEGs) are rapidly activated in response to an environmental stimulus, and most code for transcription factors that mediate processes of synaptic plasticity, learning, and memory. EGR3, an immediate early gene transcription factor, is a mediator of biological processes that are disrupted in patients with schizophrenia (SCZ). A microarray experiment conducted by our lab revealed that Egr3 also regulates genes involved in DNA damage response. A recent study revealed that physiological neuronal activity results in the formation of DNA double-stranded breaks (DSBs) in the promoters of IEGs. Additionally, they showed that these DSBs are essential for inducing the expression of IEGs, and failure to repair these DSBs results in the persistent expression of IEGs. We hypothesize that Egr3 plays a role in repairing activity- induced DNA DSBs, and mice lacking Egr3 should have an abnormal accumulation of these DSBs. Before proceeding with that experiment, we conducted a preliminary investigation to determine if electroconvulsive stimulation (ECS) is a reliable method of inducing activity- dependent DNA damage, and to measure this DNA damage in three subregions of the hippocampus: CA1, CA3, and dentate gyrus (DG). We asked the question, are levels of DNA DSBs different between these hippocampal subregions in animals at baseline and following electroconvulsive stimulation (ECS)? To answer this question, we quantified γ-H2AX, a biomarker of DNA DSBs, in the hippocampal subregions of wildtype mice. Due to technical errors and small sample size, we were unable to substantiate our preliminary findings. Despite these shortcomings, our experimental design can be modified in future studies that investigate the role of Egr3 in activity-induced DNA damage repair.

In most bird species, females disperse prior to their first breeding attempt, while males remain close to the place they were hatched for their entire lives (Greenwood and Harvey (1982)). Explanations for such female bias in natal dispersal have focused on the potential benefits that males derive from knowing the local environment to establish territories, while females search for suitable mates (Greenwood (1980)). However, the variables shaping dispersal decisions appear more complex (Mabry et al. (2013), Végvári et al. (2018)). There are a number of different variables that could act as a driving force behind dispersal including the social mating system, food competition, inbreeding avoidance, predation, and others. Here, we investigate whether females are the dispersing sex in great-tailed grackles, which have a mating system where the males hold territories and the females choose which territory to place their nest in (Johnson et al. (2000)). We used genetic approaches to identify sex biases in the propensity to disperse. In the experiment, we found that the male grackles were less related to each other while the female grackles were more related to each other. Building on that, the average distance between closely related individuals of the male group was longer than the average distance of closely related females. But, the mantel correlograms for the males and females both lack a consistent trend. Overall, the results indicated suggest that the males are the dispersing sex while the females are potentially philopatric and that the average dispersal distance for the grackle is greater than 2000 meters, the size of the sampling range used in the experiment. These results will inform our long-term study on the relationship between behavioral flexibility and rapid geographic range expansion by elucidating which individuals are likely to experience similar conditions across their lives, and which are likely to face new conditions when they become breeders.
