Description
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.

Photosynthesis is the process by which plants, algae, and bacteria use light energy to synthesize organic compounds to use as energy. Among these organisms are a kind of purple photosynthetic bacteria called Rhodobacter sphaeroides, a non-sulfur purple bacteria that grows aerobically in the dark by respiration. There have been many contributions throughout the history of this group of bacteria. Rhodobacter sphaeroides is metabolically very diverse as it has many different ways to obtain energy--aerobic respiration and anoxygenic photosynthesis being just a couple of the ways to do so. This project is part of a larger ongoing project to study different mutant strains of Rhodobacter and the different ways in which carries out electron transfer/photosynthesis. This thesis focused on the improvements made to protocol (standard procedure of site directed mutagenesis) through a more efficient technique known as infusion.

Description
This study sought to identify traits that act as possible predictors of academic science proficiency of highly gifted adolescent students. A combination of cognitive, personality, and conative traits were selected for evaluation as predictors of scientific proficiency using student General Ability Index (GAI), Revised NEO Personality Index (NEO-PI R), and Kolbe Index scores to evaluate each, respectively. Statistical correlational analyses revealed that high expressions of the conative trait Fact Finder and the personality traits Ideas and Straight-forwardness predicted higher degrees of academic science proficiency. In contrast, lower expressions of the personality traits Excitement Seeking and Order predicted higher degrees of scientific proficiency. Further, stepwise regression confirmed that the NEO-PI R facets of Excitement Seeking and Ideas traits were significant predictors of science proficiency and suggested that the personality trait Vulnerability may also be a predictor. The repeated appearance of the Excitement Seeking and Ideas facets and the dependence of the other identified traits suggests that these traits were the most promising possible predictors of scientific proficiency in highly gifted students and should be the target of future research.

Description
In 2004, the South Korean geneticist Woo-Suk Hwang published what was widely regarded as the most important research result in biotechnology of the year. In the prestigious American journal Science, he claimed that he had succeeded in cloning a human blastocyst, an embryo in its early stages (Hwang et al. 2004). A year later, in a second Science article, he made the earth-shattering announcement that he had derived eleven embryonic stem cell lines using his cloning technique (Hwang et al. 2005). The international scientific community was stunned. American scientists publicly fretted that President George W. Bush‘s 2001 executive order limiting federal funding for stem-cell research in the United States had put American bioscience behind the Koreans‘ (Paarlberg 2005). These breakthroughs offered potential solutions to immune system rejection of transplanted organs and possible cures for diseases such as rheumatoid arthritis, Parkinson‘s, Down‘s syndrome, and paralysis (Svenaeus 2007). However, within a year, Hwang was exposed as a fraud who had faked his results and pressured his female colleagues to donate eggs without informed consent. Despite protests against his methods from Korean religious and nongovernmental organizations, Hwang had used his prestige to ignore his ethical obligations. The Korean government, too, was slow to investigate Hwang and to subject his work to appropriate regulation.

Description
In vitro fertilization, or IVF, is currently a worldwide medical procedure designed to give infertile men and women the ability to have children of their own. An IVF procedure takes place outside of a woman’s body, often in a laboratory setting. However, before scientists used the procedure on humans, they initially performed IVF on animals for selective breeding and agricultural purposes. After scientists realized that the procedure had potential to become a treatment option for infertility, they expanded their research subjects to include using the technique on humans. During the procedure’s initial development, scientists began to conduct numerous IVF trials on humans that often ended in early miscarriages. This thesis shows us the history of how some of the first attempts at IVF in humans using various options such as donated egg cells and cryopreserved embryos, often ended in early miscarriages. At that time, most members of the scientific community and general public responded to those trials by regarding them as insignificant. In 1998, the success rate of women under the age of 38 having children with the use of IVF was 22.1%. Over time, scientists began to acknowledge those published findings that detailed various “failed” human IVF experiments. Scientists learned to use them as a guide for what to do differently in future IVF experiments. Because of that, scientists have since developed more effective IVF methods which have ultimately improved the procedure’s success rate. In 2016, the success rate of IVF had increased to 39.6% for women. Therefore, what we might initially think of as a “failure” is in reality not a failure at all, but rather is a “purported failure” because we can use it as a stepping-stone towards an end goal. By looking at the history of IVF research, my thesis illustrates how some of the most important science comes from acknowledging the purported failures along with the triumphant successes.

Description
HIV continues to remain a global health issue, in particular in many low and middle-income countries. The World Health Organization (WHO) estimates that of the nearly 38 million HIV-1 positive individuals, 25% are unaware they are infected. Despite decades of research, a safe and effective preventative vaccine has yet to be produced. The HIV-1 envelope glycoprotein41 and the Gag structural protein have been identified to be particularly important in HIV-1 transcytosis and cytotoxic lymphocyte response, respectively. Enveloped virus-like particles (VLPs) consisting of Gag and a deconstructed form of glycoprotein (dgp41) comprising the membrane proximal external region (MPER), transmembrane domain and cytoplasmic tail may present a unique and safe way of presenting these proteins in a state mimicking their natural formation. Another form of presenting the immunogenic glycoprotein41, particularly the MPER component, is by presenting it onto the N-terminal of an IgG molecule, thereby creating an IgG fusion molecule. In our lab, both VLPs and IgG fusion molecules are highly expressed and purified within GnGn Nicotiana benthamiana. The results indicated that these recombinant proteins can be assembled properly within plants and can elicit an immune response in mice. This provides a preliminary step in using such Gag/dpg41 VLPs and RIC as present a safe, effective, and inexpensive HIV vaccine.

Description
The Islamic Golden Era of the 9th through 11th century is considered the apex of Muslim philosophical and scientific development. Having translated, improved upon, and preserved the texts of ancient civilizations, the Abbasid Caliphate was said to be the intellectual powerhouse of its time. In stark contrast, contemporary Muslim societies are perceived by many science historians as being shadows of their former selves. This deterioration of intellectualism is thought to have started with Al-Ghazali and his Tahafut al-Falasifa, or The Incoherence of the Philosophers in the mid-11th century. Many of these scholars believe that Al-Ghazali and his influential text shifted sociopolitical power into the hands of those most against the Greeks, and consequently, against the development of philosophy and science. However, this presumption overplays the power of a single text as well as its intentions to cease intellectual pursuits.
This thesis will explore the Incoherence of the Philosophers from several layers. Attention will be given to analyzing the cultural and historical contexts by which the text was created to understand the purpose of the text and its interpretation by contemporary historians. Several theories by the historians will be explored. Additional analysis will also be conducted within the text to illustrate Al-Ghazali’s aversion to Greek metaphysics and ambivalent attitude towards philosophy. As such, this thesis will dive into the most controversial aspects of Al-Ghazali’s text, namely his criticism of the eternity of the world theory as well as his attitude on causality. The former will elucidate his willingness and mastery of philosophy, whereas the latter will be utilized to address and quell the concerns of those who believe that Al-Ghazali and his text wished to devastate the development of science in the Muslim world.

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.

Description
The Scientist in Me is an original children’s book, authored by Annmarie Barton and illustrated by Alison Lane, that explores the lives and specialties of five remarkable scientists from historically underrepresented backgrounds: Mary Anning, James Pollack, Temple Grandin, Percy Lavon Julian, and Ayah Bdeir. In the book, each scientist has an “Experiment” section that is meant to encourage children to immerse themselves in activities relating to the scientists’ areas of study. We believe that diversity in science is crucial for advancement, and therefore hope to inspire the next generation of scientists through immersion and representation.

Herpes simplex virus 2 (HSV-2) is one of the most common sexually transmitted infections (STI), affecting over 267 million women worldwide. HSV-2 causes a chronic, latent infection that increases the risk for acquisition with other STI, including HIV. Currently, there is no vaccine against HSV-2 and novel anti-viral treatments are needed. IL-36γ is a newly characterized cytokine that has been shown to play a role in inflammation and be upregulated in response to microbial infection and tissue damage. We have shown that IL-36γ is expressed in the female reproductive tract (FRT) and is upregulated by HSV-2 infection in vitro and in vivo. IL-36γ in turn induces production of proinflammatory cytokines and chemokines in human vaginal epithelial cells (VEC) that can aid in immune cell recruitment. We hypothesize that IL-36γ is a key regulator of mucosal inflammation in the FRT and functions to limit HSV-2 infection. We have demonstrated that IL-36γ treatment prior to infection protects against HSV-2 replication, disease severity, and promotes survival in a lethal mouse model. Thus, the objective of this study is to understand the mechanisms whereby IL-36γ inhibits HSV-2 replication. To understand the impact of IL-36γ on the HSV-2 lifecycle, we pretreated VEC with IL-36γ and evaluated viral titer during virus attachment and entry, replication, and cell-to-cell spread by plaque assay. Pretreatment with IL-36γ 4h prior to infection did not significantly reduce viral titers in VEC monolayers relative to untreated groups. This suggesting that IL-36γ may play a more significant role in immune cell recruitment during HSV-2 infection. To test this, FRT tissue samples from HSV-2 infected IL-36γ -/- and WT mice were analyzed by histochemistry to characterize immune cell recruitment. No clear pattern was determined for tissue samples in which cell clusters were observed and cell type within recruited clusters was unable to be identified at the current magnification. As these projects continue, the data will aid in elucidating the mechanism and level to which IL-36γ impacts HSV-2 infection in human VEC and FRT models.
