Description
Background: College freshmen are exposed to a variety of environmental and social factors that can alter changes to health habits and encourage weight gain. Weight-related conversations had with friends may be related to self-perception of weight and alterations to health behaviors, but this association has yet to be assessed in the college population.
Objective: This study aims to examine the relationship between friend advice about weight management, self-perception of weight, and alterations to weight change intentions, physical activity, and eating habits in college freshmen over time.
Methods: College freshmen from ASU with complete data for three time points (n=321) were found to be predominantly female (72.2%) and non-white (53.2%) with a mean age of 17.5±41. Complete data included responses for items included in analysis which were related to friend encouragement about weigh management, self-perception of weight, physical activity, eating behaviors, and weight change intentions. A longitudinal multivariate mediation analysis using negative binomial regression adjusted for sociodemographics and clustering by dorm was used to assess the relationship between 1) friend encouragement about weight management at time 1 and behavioral outcomes at time 3, 2) friend encouragement about weight management at time 1 and self-perception of weight at time 2, and 3) self-perception of weight at time 2 and behavioral outcomes at time 3.
Results: A small proportion of population perceived friend encouragement about weight loss (18.3%) and weight gain (14.4%) at time 1. Half the population (50.9%) had the self-perception of overweight at time 2. At time 3, more than half (54.3%) of individuals performed at least 60 minutes of MVPA and consumed at least ½ a serving of sugar-sweetened beverages each day, while nearly half (48.6%) consumed at least 2 servings of fruits and vegetables each day. Males perceived more friend encouragement to gain weight (27.4%; p<0.01), but more females had the self-perception of overweight (54%; p=0.04) and were attempting to lose weight (59.3%; p<0.01). Individuals who perceived friend encouragement to lose weight at time 1 had a 14.8% greater prevalence (p<0.001) of overweight perception of time two, and a 9.6% and 6.9%; decreased prevalence (p<0.001) of weight change and weight loss intentions (p=0.023) at time three respectively. Individuals who perceived friend encouragement to gain weight had a 34.9% decreased prevalence of (p<0.001) of self-perception of overweight at time 1. In individuals with the self-perception of overweight at time 2, there was a 18.1% increased prevalence (p<0.001) of consuming at least ½ a serving of sugar-sweetened beverages/day and an increased prevalence of 22.8% and 24.0% for weight change intentions and weight loss intentions at time 3 (p<0.001).
Conclusion: These findings suggest that there was not a mediation effect of self-perception of overweight in the relationship between friend encouragement about weight management and behavioral outcomes in the current sample. However, the increased prevalence of overweight perception in individuals who perceived friend encouragement about weight management may inform future interventions to focus on how weight-related conversations with friends is related to overweight perception. More research about the relationship between weight-related conversations had with friends, self-perception of weight, and health behaviors is needed to confirm these findings.

Description
Strategies are needed to improve repopulation of decellularized lung scaffolds with stromal and functional epithelial cells. We demonstrate that decellularized mouse lungs recellularized in a dynamic low fluid shear suspension bioreactor, termed the rotating wall vessel (RWV), contained more cells with decreased apoptosis, increased proliferation and enhanced levels of total RNA compared to static recellularization conditions. These results were observed with two relevant mouse cell types: bone marrow-derived mesenchymal stromal (stem) cells (MSCs) and alveolar type II cells (C10). In addition, MSCs cultured in decellularized lungs under static but not bioreactor conditions formed multilayered aggregates. Gene expression and immunohistochemical analyses suggested differentiation of MSCs into collagen I-producing fibroblast-like cells in the bioreactor, indicating enhanced potential for remodeling of the decellularized scaffold matrix. In conclusion, dynamic suspension culture is promising for enhancing repopulation of decellularized lungs, and could contribute to remodeling the extracellular matrix of the scaffolds with subsequent effects on differentiation and functionality of inoculated cells.

Description
Extra-intestinal pathogenic E. coli (ExPEC), including avian pathogenic E. coli (APEC), pose a considerable threat to both human and animal health, with illness causing substantial economic loss. APEC strain χ7122 (O78∶K80∶H9), containing three large plasmids [pChi7122-1 (IncFIB/FIIA-FIC), pChi7122-2 (IncFII), and pChi7122-3 (IncI2)]; and a small plasmid pChi7122-4 (ColE2-like), has been used for many years as a model strain to study the molecular mechanisms of ExPEC pathogenicity and zoonotic potential. We previously sequenced and characterized the plasmid pChi7122-1 and determined its importance in systemic APEC infection; however the roles of the other pChi7122 plasmids were still ambiguous. Herein we present the sequence of the remaining pChi7122 plasmids, confirming that pChi7122-2 and pChi7122-3 encode an ABC iron transport system (eitABCD) and a putative type IV fimbriae respectively, whereas pChi7122-4 is a cryptic plasmid. New features were also identified, including a gene cluster on pChi7122-2 that is not present in other E. coli strains but is found in Salmonella serovars and is predicted to encode the sugars catabolic pathways. In vitro evaluation of the APEC χ7122 derivative strains with the three large plasmids, either individually or in combinations, provided new insights into the role of plasmids in biofilm formation, bile and acid tolerance, and the interaction of E. coli strains with 3-D cultures of intestinal epithelial cells. In this study, we show that the nature and combinations of plasmids, as well as the background of the host strains, have an effect on these phenomena. Our data reveal new insights into the role of extra-chromosomal sequences in fitness and diversity of ExPEC in their phenotypes.

Objectives: To explore the feasibility and effects of using a meditation mobile app 10-minutes a day for 4-weeks to reduce burnout (primary outcome), improve mindfulness, reduce stress, and depression in physician assistant (PA) students compared to a wait-list control.
Methods: This study was a randomized, wait-list, control trial with assessments at baseline and post-intervention (week 4). Participants were asked to meditate using Calm for 10 minutes per day. A p value ≤0.05 was considered statistically significant.
Results: The majority of participants (n=19) stated using Calm helped them cope with the stress of PA school. The intervention group participated in meditation for an average of 76 minutes/week. There were significant differences in all outcomes for the intervention group (all p ≤0.06). There was a significant interaction between group and time factors in emotional exhaustion (p=.016) and depersonalization (p=.025).
Conclusions: Calm is a feasible way to reduce burnout in PA students. Our findings provide information that can be applied to the design of future studies.

Description
Spasticity is a neurological disorder in which a target group of muscles remain in a contracted state. In addition to interfering with the function of these muscles, spasticity causes chronic pain and discomfort. Often found in patients with cerebral palsy, multiple sclerosis, or stroke history, spasticity affects an estimated twelve million people worldwide. Not only does spasticity cause discomfort and loss of function, but the condition can lead to contractures, or permanent shortenings of the muscle and connective tissue, if left untreated. Current treatments for spasticity are primarily different forms of muscle relaxant pharmaceuticals. Almost all of these drugs, however, carry unwanted side effects, including total muscle weakness, liver toxicity, and possible dependence. Additionally, kinesiotherapy, conducted by physical therapists at rehabilitation clinics, is often prescribed to people suffering from spasticity. Since kinesiotherapy requires frequent practice to be effective, proper treatment requires constant professional care and clinic appointments, discouraging patient compliance. Consequently, a medical device that could automate relief for spasticity outside of a clinic is desired in the market. While a number of different dynamic splints for hand spasticity are currently on the market, research has shown that these devices, which simply brace the hand in an extended position, do not work through any mechanism to decrease spastic tension over time. Two methods of temporarily reducing spasticity that have been observed in clinical studies are cryotherapy, or the decrease of temperature on a target area, and electrotherapy, which is the delivery of regulated electrical pulses to a target area. It is possible that either of these mechanisms could be incorporated into a medical device aimed toward spastic relief. In fact, electrotherapy is used in a current market device called the SaeboStim, which is advertised to help stroke recovery and spastic reduction. The purpose of this paper is to evaluate the viability of a potential spastic relief device that utilizes cryotherapy to a current and closest competitor, the SaeboStim. The effectiveness of each device in relieving spasticity is reviewed. The two devices are also compared on their ability to address primary customer needs, such as convenience, ease of use, durability, and price. Overall, it is concluded that the cryotherapy device more effectively relieves hand spasticity in users, although the SaeboStim's smaller size and better convenience gives it market appeal, and reveals some of the shortcomings in the preliminary design of the cryotherapy device.

Description
Regardless of religious beliefs, all one has left when they leave this Earth is the meaning the individual has derived from building connections and relationships with other people. I propose whether or not one is able to reach his or her potential and the quality of life that follows is based inherently in the following question: How will you manifest your truth into reality, thus becoming the best at your profession or craft, and spreading your gifts to help the lives of others? The answer to this question, and ultimately the key to leading the best life available is in the equation: vulnerability through playfulness and connection instigates happiness, which results in spreading positivity and facilitating the ability to make fearless decisions that guides one's life as an artist or profession of one's choosing, leading one to their highest potential. This theory applies to everyone and does not discriminate. This is the beginning of a life-long exploration and discovery with these elements as I further my work as an artist, and I will explore these themes from my exposure to the Balinese people and culture, our theatre workshops and experiences there, and through additional inspiration and research. The workshop and clowning in Bali training helped form the theory I have proposed, and further introduced a different approach to acting that I utilize in my own work that incorporates taksu: an achievable state of being that is unanimously understood by the Balinese that influences and shapes how they approach life, work, and each other that I discuss more extensively in my work. I will continue to inquire about how one finds space for imagination and pursuit of taksu without traveling, although traveling is an amazing way to broaden one's scope of perspective. The combination of elements discussed and taksu help create a humanity that is more in touch with inner peace and happiness as a result of spreading both positivity and a positive mindset to others. This in turn, influences and shapes performance and how we approach the craft of acting, while creating emotional truth and integrity within one's craft.

Description
Arizona State University and Banner Thunderbird Hospital have partnered to provide pre-med students with an internship at a local emergency department. Students entering into this program will have access to each patient's vital signs, medical imaging, lab tests, and medications. This access presents students with an opportunity to learn about a variety of tools used in the assessment and treatment of emergency room patients. In order to enhance the amount of knowledge students take away from the program, I created a handbook summarizing a variety of diagnostic tests and medications. The first section of the handbook (assessment) is spilt up into the three following categories: vital signs, medical imaging, and lab tests. The second section (treatment) consists of one category, medications. Each section was written with emphasis on basic physiology, and is intended to provide pre-med students with a foundation for building further medical knowledge. Although this handbook was tailored to the information students are most likely to encounter working in Banner Thunderbird Hospital's emergency department, it is still appropriate for any student interested in learning about emergency medicine.

This creative group project aims to bring visibility to the diversity of the LGBTQ+ community at Arizona State University by sharing the personal stories and opinions of people from across ASU's rainbow spectrum. Created and produced by a gay couple that met in their first year dorm and a passionate ally, gAySU: Exploring Sparky's Rainbow is a compilation of photos, videos, and stories from ASU students, faculty, and staff that identify with the LGBTQ+ community. When reflecting on their own journey over the past three years, gAySU's creators recognized ASU can feel large with many pockets of communities, yet through trial and error over the past 4 years they managed to explore their identities and grow as individuals, as a couple, and as an ally. By sharing their story and the stories of others, it is the hope that gAySU allows its readers and viewers an insight into what it means to be both a Sun Devil and LGBTQ+, and for those new to or anxious to identify with the LGBTQ+ community, to understand they are not alone in their journey and that it is okay to bleed maroon, gold, and all other colors of the rainbow.

This thesis explores the various reasons that Broadway musicals fail, or "flop". It goes into detail on several musicals of different genres, and explains what their shortcomings were, whether it be a less-than-perfect book, a weak score, or a production team that was not experienced in the skills that it takes to put together a musical. It discusses how long the shows ran for, or if they ever made it into a Broadway house. It looks at what the audience reception was like for each show, and whether the shows were a success with the tough critics of Broadway. In addition to this, I have recorded several of my peers performing songs from the musicals I have discussed in the written portion of this thesis. This helps to educate an audience on what it would have been like for one of the flop's real performances. The videos also do a wonderful job of communicating what the show sounds like, and how it can make an audience feel or react. Lastly, it gives more insight into why the musicals they are from failed to thrive in front of a Broadway audience. Through my research, I have discovered that creating a musical is possibly one of the most difficult feats a team of creative people can accomplish. There are countless reasons for failure in these shows, but overall, I feel that every failure had something to offer, and because of that, are surely worth celebrating.
