Ransomware is malicious software which restricts users from accessing their computer and personal data through encryption. Ransomware attacks target a variety of victims including individuals, organizations, businesses, and governments. Attackers take control of this sensitive data and hold it hostage until a ransom is paid. Whether or not ransom is paid, the attackers’ damage can be irreparable. It includes but is not limited to exposing personal information, identity theft, blackmail, permanent deletion or corruption of valuable data, and Distributed Denial-of-service (DDos). Moreover, the financial implications of ransomware attacks are substantial. Victims face not only the direct costs of ransom payments, but also the expenses associated with system restoration and the potential fines for data protection violations. Furthermore, an ethical dilemma emerges from the response to extortion, as victims must grapple with the moral implications of potentially supporting criminal activities by paying ransoms to recover their data. This raises questions about the broader responsibility of stakeholders in cybersecurity and their duty to protect data privacy. The first ransomware attack emerged in 1989 and since then, ransomware attackers have persisted as a cybersecurity threat, striking at the core of data privacy. This paper delves into the multifaceted impact of ransomware incidents on data security, current ransomware techniques and strategies, and the ethical dilemmas they raise.Because ransomware attackers are constantly evolving their methods, it is important to routinely review the current literature to fully understand the tactics and techniques used by these cybercriminals. This research paper will review, analyze, and synthesize the existing literature about ransomware. It is crucial for individuals and organizations to be proactive, understand the nature of the threat, and take precautions to protect themselves and their data. This study encourages further research and discourse on the multifaceted impact of ransomware attacks on data privacy and the pursuit for effective countermeasures.

This research explores the relationship between Latter-Day Saint views and classical Christianity through the lens of the problem of evil. More specifically, this research looks at the implications both Augustine’s theory of evil and Latter-Day Saint theology have on each other and the impact that would occur should certain aspects be accepted by Latter-Day Saints. I argue that Latter-Day Saints should accept an interpretation of doctrine through the privation theory of evil in order to avoid potential threats to God’s goodness and the Plan of Happiness. Understanding Latter-Day Saint doctrine through this lens will better situate further research in the broader context of Christianity. Furthermore, accepting this theory will allow for a deeper understanding of the premortal existence and postmortal states. This deeper understanding is beneficial for both adherents to and researchers of Latter-Day Saint teachings. Finally, I argue this interpretation does not pose a threat to the doctrine of “opposition in all things.”

Prior to 1930, cannabis was used frequently in therapeutic practices and was found in many over the counter health products. However, around this time what has been dubbed the “pot panic” began infecting American citizens. It was then the film Reefer Madness came onto the scene, exacerbating the public’s trepidation over the allegedly morally degrading effects cannabis inflicted. Putting melodrama at the forefront, the film exploits societal queasiness over sex, drugs, violent crime, and immigration to push its propagandist agenda. The fear mongering rhetoric and imagery used effectively poisoned the public and altered societal perceptions of medical and recreational cannabis use. The goal of this project is to analyze the rhetorical argument presented in the film and address its broader reach and effects. Lastly, I will argue that the message presented in Reefer Madness was not based on any logical argument; it was based on folklore.

Authors: Natalya Misener, John Wolfe. Mentors: John Wolfe. Insitution: Utah Tech University. In our effort to improve education and create a more inclusive learning environment, Natalya Misener and Professor John Wolfe from Utah Tech University are exploring the experiences of neurodivergent students in classrooms. Our goal is to better understand, support, and empower these students, challenging the way things are typically done. We believe it's important to understand that these conditions come in a variety of forms and affect both students and professors in the classrooms in ways that are not currently being discussed, especially as many minorities, especially women and people of color, go undiagnosed and unaccommodated for a variety of reasons. We believe that by educating professors and students alike on how classroom environments can be more supportive of neurodivergent students, we can benefit the entire classroom, including ‘typical’ students. To make this happen, we believe it's important to rethink how we organize our classes, assignments, and interactions, so that we don't have to rely too much on services like the Disability Resource Center (DRC). We have practical suggestions, like adjusting assignments and deadlines and creating a comfortable classroom environment. It's also crucial to be clear in our expectations and listen to what the students need. We ask some important questions, like whether students should consider their instructors' limitations and how students see disabled instructors in their journey to graduation as well. We call for a shift beyond just accommodating neurodivergent students. We want to encourage educators to think about how they can better support all students in their classrooms. It's urgent that we change how we approach neurodivergent students- in order to create a more inclusive, supportive, and successful environment for us all.

Antibiotic resistance is a pressing concern within the medical community as bacteria's resistance to antibiotics is escalating alongside the increased usage of antibiotics. According to the CDC, there are close to 2.8 million antibiotic resistant infections every year, with about 35,000 of them resulting in death. This issue has prompted antibiotic stewardship programs in clinics and hospitals to avoid adding to the list of resistant bacteria. Staphylococcus aureus, including the formidable methicillin-resistant S. aureus (MRSA) strain, poses a grave threat due to its antibiotic resistance. The challenges stemming from this resistance become even more formidable when these infecting bacteria assemble into biofilms. Biofilms are robust, adhesive layers composed of bacteria and their extracellular matrices of polysaccharides, proteins, and DNA. In clinical environments like hospitals, biofilms frequently develop on medical devices such as stents, catheters, and IV lines, as well as on metal and plastic surfaces of medical equipment. These biofilms exacerbate antibiotic treatments due to incomplete eradication; the most resilient bacteria persist after exposure. There is evidence indicating that bacteriophages, which are viruses that will a target particular species or strain of bacteria, have the ability to encode depolymerases. These depolymerases can identify biofilms, adhere to them, and subsequently break down extracellular polymeric substances. Furthermore, bacteriophages can produce lysins, which induce bacterial cell death through cellular lysis. These characteristics can potentially render the bacteria more susceptible to antibiotics. The use of bacteriophages can also be beneficial when it comes to the concern of opportunistic infections. Due to its selectivity to specific bacteria, it can attack the target hosts and leave the natural flora intact.In our research, we have induced biofilms in our bioreactor. With these biofilms we have been able to test different concentrations of multiple antibiotics, including Vancomycin, Oxacillin, and Carbenicillin in combination with phage K at different concentrations. Our research is aimed at showing a synergistic relationship between phage K and antibiotics, that will allow a subinhibitory concentration of both, in combination, to induce a complete kill and clearance. We have measured this by evaluating bacterial growth via absorbance measurements at 600nm in a Tecan plate reader. We have also measured biofilm clearance using the plate reader and measuring fluorescence at 630nm with a biofilm tablet assay. It was found that a subinhibitory concentration of antibiotic alone did not induce a complete kill and clearing, and that a subinhibitory concentration of phage alone did not induce a complete kill and clearing. However, once these concentrations were used in combination with each other, the complete clearing and killing of MRSA was achieved, and furthermore, was achieved with the antibiotic that the staphylococcus aureus is resistant to. Leading us to believe that we have found a renewed use for a currently ineffective defense mechanism.

For this presentation, I will present a care ethics analysis of Web3 and decentralized internet, with a specific focus on privacy concerns and the increase of internet scams due to the lack of regulation and accountability. Ethics of care argues that there is moral importance in promoting the well being of care givers and receivers in a network of social relations, recognizing that all human life is co-dependent. It is important to note that care ethics was not designed to engage with such large networks of relationships, I will be expanding it to apply to the situation, so it gives us one new way of viewing the situation. I will expand on this ethical lens by including points from care ethics such as the empathy in the design of Web3, and responsibility for online communities. My research explores the intricate web of relationships and responsibilities in the decentralized environment, aiming to shed light on the vulnerabilities within internet scams in contrast to the benefits of cryptocurrency. I examine the moral dimensions of these scams, considering the impact on individuals and the broader digital community. The emphasis on care ethics demonstrates the interconnectedness of actors within Web3, as well as the need for a collective commitment to certain forms of innovation.

Authors: Nate Lovett. Mentors: Harish Bhatt. Insitution: Utah Valley University. Coupled nonlinear Schrödinger equations (CNLSEs) are an extension of the nonlinear Schrödinger equation (NLSE) that applies to multiple interacting wave systems. They occur naturally in many physical systems, including nonlinear optics, multi-component Bose-Einstein condensates, and shallow water waves. Solitons, which are self-contained, localized wave packets that preserve their shape and speed during propagation, are a significant application of CNLSEs. Solitons are prevalent in nonlinear systems and play a critical role in long-distance information transmission in telecommunications. Despite their widespread use in various fields, solving CNLSEs analytically is challenging, and numerical approximations are necessary. However, solving CNLSEs numerically is a difficult task because of their high nonlinearity.To overcome this challenge, in this presentation, we will introduce, analyze, and implement an established fourth-order Exponential Time Differencing scheme in combination with the Fourier spectral method for simulating one-dimensional CNLSEs. In order to check the performance of this method in terms of accuracy, efficiency, and stability, we will present simulation results on CNLSEs. Our results will consider single, two, and four soliton interactions for homogeneous Neumann, homogeneous Dirichlet, and periodic boundary conditions. The numerical results will show that the proposed method is able to preserve energy and mass for a long time simulation in soliton interactions, as well as preserve the expected order of convergence for the proposed method.

Our study examines a viral video featuring a dog named Fritz who consistently fails to catch thrown food items. This research aims to determine whether Fritz's inability to catch is a result of his owner's throwing technique or Fritz's own inherent clumsiness. To investigate this, we employ a mathematical model based on kinematic differential equations to analyze the rotational dynamics of various geometrical shapes that simulate the thrown food items. By pinpointing moments in the projectile trajectory where the food items are most easily caught, we provide empirically-based recommendations aimed at improving Fritz's success rate.

The Bonneville cutthroat trout (Onchorynchus clarki utah) is the only trout species native to the Northern and Southern Snake ranges in Eastern Nevada. Streams on the east side of both ranges flowed into Lake Bonneville 12,000 – 15,000 years ago when Lake Bonneville was at its maximum. As Lake Bonneville retreated, Bonneville cutthroat trout in these streams were left isolated. To better understand how Bonneville cutthroat trout in the study area are coping with a changing climate, we Investigated the genetic diversity of Bonneville cutthroat in the Northern and Southern Snake ranges and compared them to historic samples. We found highly differentiated cutthroat trout populations in close proximity to each other and a genetic diversity loss of up to 86.3% in the last 12 years.

Ecological Niche Modeling (ENM) is a very useful technique that gives us insight into a species’ present and possible future ranges, habitats, and niches. ENM has applications within conservational biology as models can be used to understand the extent to which climate change may impact a species. Additionally, ENM can be useful for prospecting for and propagation of rare plant species. This project will use ENM to create predictive range models for a rare plant species, Pediomelum aromaticum, with the goal of defining an ecological niche, determining impact of climate change, and general conservation of P. aromaticum. Here, we will compare 19 bioclimatic variables using correlation analysis and ecological niche modeling to determine which are the most impactful on the range of P. aromaticum. Additionally, ENMs will be created using the MAXENT algorithm from historical and predicted future climate data. By comparing these models, we can hypothesize as to how climate change may impact P. aromaticum. Finally, models will be compared between predicted climate futures defined as shared socio-economic pathways or SSP. SSP models estimate the impacts of human interactions within the scope of environment, governments, and each other to estimate the impact of varying sets of human interactions as defined by modified global behaviors within humanity and the impacts on global climate change. Different ENM models will be created with different SSP climate models so that we can understand how actions taken by humanity right now may impact the critically imperiled species P. aromaticum.

In addition, use of 3D printed parts can be more economical and less labor intensive.However, the mechanical behavior of these plastics is not well defined. There are many factors that affect the integrity of 3D printed plastic – extrusion temperature, infill pattern and infill percentage being a few of them.In this work, authors have attempted to study the effect of these factors on the tensile and flexure (bending) strength of 3D printed plastics. Firstly, tensile and bending samples are prepared by varying on more of the following – extrusion temperature, infill patter and infill percentage. Further, the specimens are tested in a destructive manner for tensile and flexure strength following the standard tensile and three-point bending technique on a Materials Testing System. The results on the variation in the strength as a function of print parameters provides an insight on the importance of standardizing these parameters to maximize strength and minimize cost.Keywords: additive manufacturing, 3D printed plastic, tensile strength, flexure strength

Authors: Alexander Panin, Benjamin Miera. Mentors: Alexander Panin. Insitution: Utah Valley University. Recent searches for extrasolar planets have brought a surprising discovery – almost any star seems to have a planetary system around it. We know that massive stars end their lives in a violent supernova explosion, during which an extremely large amount of energy (~3x10^46 J) is released from the star in a very short time. In this presentation, we analyze the effect of this explosion – primarily the impact of the neutrino flash, the gamma ray flash, and the expanding plasma shell - on the mechanical and thermal stability of an orbiting planet. Our calculations show that a planet's orbit can be significantly disrupted by the momentum of the exploding star shell (depending on the planet's mass and proximity to the host star), but the radiation pressure from the explosion has a much weaker effect. If a star loses too much mass to the expanding shell, any previously stable orbit will become unstable, causing the planets to escape. Additionally, we found that the gamma ray flash and the plasma shell incident on the planet can cause significant heating, while the neutrino flash would have virtually no effect. Also, if a star’s collapse is asymmetric then the star itself can leave the planetary system due to the momentum of the asymmetric neutrino radiation. The sequence of events during a supernova explosion and how they influence such a planet is discussed in the presentation.

Authors: Maren Archibald. Mentors: Jared Colton. Insitution: Utah State University. Two-factor authentication was in use as early as 1994 with a patent belonging to telecommunications company Ericsson, which described the tech as “an authentication unit which is separate from preexisting systems." Today, multifactor authentication (MFA) requires a user to prove their identity by way of their knowledge, through a password or one-time code; their possession, through a physical key; or their inherence, through biometrics like a fingerprint or an eye scan. The secure sign-in method has proliferated in recent years, but while significant time has been dedicated to refining it, little if any research has been done in relation to its ethical implications. In his scholarship on discipline, Michel Foucault writes of “examination that places individuals in a field of surveillance.” MFA is one such method of surveillance — various forms track users’ location data, common usage and login hours, and biometric information. In my presentation, I will apply Foucauldian ethics to show how MFA is uniquely situated among other forms of societal documentation because of its purpose. The very data that depersonalizes users into numbers is also meant to be so precise and personal that it is the only way to believe users are who they say they are. And beyond MFA’s treatment of individual users looms the widespread collapse of a distinction between privacy and security. These values are not incompatible, but organizations have implemented MFA in a way that requires users to sacrifice privacy in order to gain security. My research will show how MFA aggrandizes the power differential between users and tech giants and threatens the ability to simultaneously maintain privacy and digital identity.

Authors: Parker Graves, Landon Deru, Bruce Bailey. Mentors: Bruce Bailey. Insitution: Brigham Young University. Chronic illness such as strokes, heart disease and diabetes all rank among the leading causes of death in the United States. Recently, fasting has gained popularity as a means of preventing and treating chronic illness. PURPOSE: Fasting produces multiple beneficial physiological responses that have been shown to aid in chronic disease prevention, one of which is observed in relation to incretin hormones such as glucose-dependent insulin tropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1). These incretin hormones are released by the gut to augment the secretion of insulin to regulate postprandial glucose levels. During a fast, the decrease in incretin hormones, and resultant insulin levels can aid the body to regain insulin sensitivity. This can lead to more effective blood glucose management and chronic illness prevention. The purpose of the study was to determine the impact of an acute 24-hour fast started with either a high fat (HF) or high carbohydrate (HC) meal on plasma GIP and GLP-1. METHODS: Subjects were over the age of 55, had a BMI equal to or greater than 27, and had no diagnosed metabolic disorders or some other disqualifying medical issues. Using a randomized crossover design, each participant performed two 24-hour fasts. One fast beginning with a high carbohydrate meal and the other a high fat meal, both of equal calories. Venous blood draws were taken at 0, 1, 24, and 48 hours. RESULTS: GIP and GLP-1 (P < 0.001) were both elevated 1 hour after consuming the pre-fast meal in both conditions. In addition, both GIP (P = 0.0122) and GLP-1 (P = 0.0068) were higher in the high fat condition compared to the high carbohydrate condition at 1 hour. There were no significant differences between conditions for either GIP or GLP-1 at any other time point. CONCLUSION: As expected, both incretin hormones spiked postprandially. We did find that GIP and GLP-1 levels were significantly higher at 1-hour postprandial for the HF meal compared to the HC meal. This could give evidence to show how macronutrient levels can affect incretin secretion and alter sensitivity to insulin. However, the impact of the pre-fast meal on GLP-1 and GIP did not persist throughout the fast.

Authors: Leila Moore, Marin Farnsworth. Mentors: Tyson Harmon. Insitution: Brigham Young University. Background:Facial expressions are crucial for understanding human emotions in communication. Coding and quantifying these expressions, however, have often been subjective, leading to issues with reliability and consistency (Kring and Sloan, 2007). To address this, we have modified the Facial Expression Coding System (FACES) protocol (Kring and Sloan, 2007), which traditionally relies on subjective interpretation. Our modified protocol employs a more objective approach by quantifying facial expressions based on the counting of facial units (e.g., eyes, corners of the mouth, eyebrows, and teeth). Each intensity rating corresponds to a certain number of facial units. For example, an expression involving one facial unit would receive an intensity rating of one whereas an expression involving two units would receive an intensity rating of two. Multiple studies have found that women are more emotionally expressive than men overall when considering gestures, body language, facial expressions, and tone of voice (Ashmore, 1990; Brody & Hall, 1993; Hall, 1984). Rather than focusing on overall emotional expressiveness, though, the present study aims to understand how gender impacts the production of emotional facial expressions specifically. Method:The proposed study aims to compare the frequency and intensity of facial expressions produced by men versus women when recounting personal narratives. Participants. Video footage from participants with and without aphasia producing personal narrative discourse will be obtained for equal numbers of male and female participants. Samples will include two personal narratives in response to prompts from the interviewer. The first prompt is to speak of an experience the participant has had with illness/injury/stroke, and the second prompt is to talk about an important event that has happened in their life. Procedure. A modified FACES protocol will be used to code facial expressions in videos obtained from AphasiaBank. The coding process is conducted with the audio muted to help eliminate distractions. The modified FACES protocol includes specific, operationalized criteria for what qualifies as a facial expression. This protocol does not include coding non-facial gestures or eye movements. However, we do take into account the narrowing and widening of eyes in addition to instances when the eyes are opened or closed with intention. A critical question we ask during coding is whether the facial expression conveys emotional content. We have established standards for intensity ratings and will outline how we arrived at these standards, as well as the distinctions between intensity ratings one, two, three, and four. The analysis process includes establishing a baseline expression for each participant and coding for 20 minutes before taking a break to maintain energy and productivity and to ensure accuracy in data collection. Additionally, secondary coding and a final pass for gestalt ratings are performed to ensure comprehensive analysis.Data Analysis. To address our research questions, we will conduct a comprehensive analysis, focusing on our participants' facial expressiveness during personal narrative storytelling. The analysis will involve quantifying the frequency of facial expressions exhibited by the participants. Additionally, we will consider the valence of these expressions, distinguishing between positive and negative emotional content. We will also assess the intensity of facial expressions by counting the number of facial units engaged during each expression. This examination of facial data will allow us to discern not only the prevalence of expressions but also emotional content and intensity, ultimately providing a more in-depth understanding of the gender differences in non-verbal communication during personal narratives.Anticipated Results:Our study aims to explore if there is a statistically significant difference in the quantity, valence, and intensity of facial expressions between men and women. By using a standardized approach for measuring emotional facial expression production, we hope to shed light on the nuances of non-verbal communication during personal narratives and contribute to a better understanding of gender differences in emotional expression. Consistent with previous research, we anticipate that females will produce more frequent and intense emotional facial expressions than males (Ashmore, 1990; Brody & Hall, 1993; Hall, 1984).References:Ashmore, R.

ACSM has again determined that resistance training (RT) and outdoor activities are two of the top ten worldwide fitness trends for 2023. We previously found that RT outdoors had a significantly lower perception of effort (RPE) compared to indoor RT, despite no physiological differences in heart rate (HR) and energy expenditure (EE). However, no study has examined other feelings during RT in indoor or outdoor settings. PURPOSE: To determine how indoor or outdoor environments effect perceptions of fatigue and physical activity enjoyment following RT in recreationally resistance trained adults. METHODS: Twenty-three adult participants (n=10 female, n=13 male) completed this study. The Visual Analog Scale Fatigue (VAS-F) measured perceived fatigue and the Physical Activity Enjoyment Scale – Short Version (PACES-S) measured PA enjoyment, and both were measured at baseline and then immediately following an acute session of indoor or outdoor RT. HR was obtained from a chest strap (Polar H10) and EE from a Portable Metabolic Cart (COSMED K5). Randomly in indoor and outdoor settings, participants completed 4 supersets of the reverse lunge and shoulder press exercises using dumbbells at a light (2 sets) and moderately heavy (2 sets) intensity with 1 superset of 6 repetitions per exercise and 1 min rest between supersets. A paired T-test (for HR & EE comparisons) or one-way repeated measures ANOVA with Sidak post-hoc test (for VAS-F & PACES-S comparisons) were used to determine differences (p<0.05). RESULTS: No significant differences were observed between indoor and outdoor RT for the physiological variables of average HR (129.4±17.2 and 127.75±23.3 bpm, respectively, p=0.66) and EE (30.6±11.5 and 28.3±9.9 kcals, respectively, p=0.06). Perceived fatigue significantly (p<0.0001) increased from baseline (1.13±0.94 arbitrary units, AU’s) following indoor (4.54±1.91 AU’s) and outdoor (3.99±1.54 AU’s) RT, but no environmental differences (p=0.36) were observed. PA enjoyment was not significantly (p range: 0.27-0.93) different between baseline (18.73±1.83 AU’s) and following indoor (18.18±1.99 AU’s) or outdoor (18.36±1.99 AU’s) RT. CONCLUSION: In recreationally resistance trained adults, moderately heavy superset RT in indoor or outdoor settings does not alter perceived fatigue or physical activity enjoyment.

Healthcare access disparities remain a persistent and pressing issue in the community, disproportionately affecting marginalized communities. These disparities include aspects such as geographic location, socioeconomic standing, and ethnicity, all of which can hinder individual and societal growth. Addressing these disparities is vital as it can improve the well-being of individuals and therefore society. Examining the nature of healthcare access disparities helps present a holistic approach that can help bridge the gap, providing a more equitable healthcare system. Healthcare disparities are deeply embedded in the network of social and structural inequalities, driven by a complex interplay of geographical, economic, and cultural factors. Such disparities create health gaps, where individuals from marginalized communities are disproportionately burdened by a lack of access to essential medical services. The historical neglect of underserved communities has contributed to the persistence of these disparities, necessitating a comprehensive and transformative approach to address the problem.Effectively combating healthcare access disparities includes implementing community involvement that empowers underserved communities, enacting healthcare policy reforms to address systemic barriers, and leveraging locum tenens to improve access to care in all areas. Addressing these aspects will lead to a more equitable and inclusive healthcare system, that results in improved health outcomes and well-being for all individuals. Addressing healthcare access disparities is essential for individual and community improvement. Through community engagement, healthcare reforms, and the use of locum tenens a comprehensive approach can be represented in regards to a more equitable and inclusive healthcare system.

IntroductionPersonalized cancer care requires molecular characterization of neoplasms. While the research community accepts frozen tissues as the gold standard analyte for molecular assays, the source of tissue for all testing of tumor tissue in clinical cancer care comes almost universally from formalin-fixed, paraffin-embedded tissue (FFPE). Specific to genomics assays, numerous studies have shown significant discordance in genetic information obtained from FFPE samples and cryopreserved samples. To explain the discordance between FFPE samples and cryopreserved samples, a head-to-head comparison between FFPE and cryopreserved tissues was performed to analyze the DNA yield, DNA purity, and DNA quality in terms of DNA length.MethodsHuman (n = 48) and murine tissues (n = 10) were processed by traditional formalin fixation and paraffin embedding or placed in cryovials containing HypoThermosol solution. 19 human-matched samples were included. These cryovials were cooled to -80°C slowly and stored in liquid nitrogen until the time of the study. DNA was extracted using the same protocol for both tissue types except that tissues embedded in paraffin were first dewaxed using a xylene substitute followed by a multistep rehydration protocol using ethanol and water. Samples were weighed and calibrated to have the same starting mass. After the column purification, samples were eluted in 20 µL and concentration and purity were measured on a Nanodrop. Purity was determined by calculating the 260/280 ratio. DNA fragment length was measured on an Agilent Fragment Microelectrophoresis Analyzer.ResultsGraded amounts of tumor tissue (5- >50 mg) were used to determine the lowest starting material needed to extract 40 ng/mg of DNA. The average for both sample types reached the minimal threshold of 40 ng/mg. However, 74% of FFPE specimens failed to meet the minimum 40 ng/mg, whereas only 21% were below the threshold in the cryopreserved samples (Figure 1). In the cryopreserved group, the average DNA yield was 222.1 ng/mg, whereas 52.8 ng/mg was obtained from FFPE tissue. For DNA purity in cryopreserved tissues, the 260/280 ratio range was 1.09-2.13 with a mean of 1.79. The 260/280 ratio range in FFPE tissues was 0.85-2.76 with a mean of 1.65 (Figure 2). The DNA Quality Number(DQN) is a measurement of DNA fragment length and the percentage that exceeds the threshold of 300 bp. For FFPE, the DQN was 4.4 compared to a DQN of 9.8 for the cryopreserved samples (Figure 3). Setting a higher threshold of DNA length to 40,000 bp and measuring the area under the curve (AUC), it was observed that cryopreserved samples were 9-fold higher in fragments greater than 40,000 bp (Figure 4).ConclusionsCryopreserved cancer tissue provides superior quality assurance measurements of DNA over FFFPE. Treatment decisions based on molecular results demand accuracy and validity. The pathology community should support efforts to cryopreserve cancer biospecimens in the clinical setting to provide valid molecular testing results. The automatic pickling of tumor specimens in formalin is no longer an acceptable default.

Authors: Ashley Allan, Mikayla Kimball, Noah Bezzant, Brent Feland, Josh Sponbeck. Mentors: Brent Feland. Insitution: Brigham Young University. BACKGROUND: Recent studies have shown that there are differences bilaterally in the cross sectional area of the patellar tendon for lead vs non lead extremities of athletes. Yet, little research can be found as to whether there is a difference that develops over one’s lifetime between the stiffness of the patellar tendons in the dominant vs non-dominant legs. Reliability has not yet been established for elastography in the patellar tendons, so we are continuously striving to gather more reliable data on shear-wave elastography of the patellar tendon. PURPOSE: The aim of this study was to assess whether there is a difference in the average patellar tendon stiffness as measured by ultrasound elastography using a pad vs no pad and differences between self reported non-dominant vs dominant knee of senior athletes over the age of 50. Dominance taken as reported in a modified KOOS (Knee Injury and Osteoarthritis Outcome Score) survey. METHODS: Data was collected from 15 active, senior aged volunteers at the Huntsman World Senior Games in St George, Utah, 2023. All subjects (mean age= 67.29 ± 6.26 yrs, height=175.44 ± 8.18 cm, weight=87.40 ± 12.21 kg) signed an approved consent and completed a modified KOOS survey. Following, they were seated on a table, with their backs against the wall directly behind them. They were seated so that their lower legs were hanging off of the table in a relaxed position. The patellar tendon was then imaged with a long axis view using ultrasound elastography. ANALYSIS: All data were analyzed using JMP ver16.2 with a repeated measured analysis of variance (ANOVA) to determine if differences existed between pad and no pad and between dominant and non- dominant legs. RESULTS AND CONCLUSION: There was a significant difference between (p=.0423) pad and no pad patellar tendon measurements, but no significant difference when comparing sides combined with pad and no pad, between dominant and non-dominant legs, although a trend for significance did exist, and we suspect that with more subjects analyzed, we will get more significance.

In the dynamic game of professional football, where split-second decisions and explosive movements often determine the outcome, players train all year round for optimal athletic performance. Paramount to this performance are the hamstring muscles including the semimembranosus (SM), semitendinosus (ST), and both the long and short head of the biceps femoris (BFLH and BFSH). They play pivotal roles in sprints, agility, jumping, and overall lower-body strength. Because of the critical nature of the hamstrings during functional activity, this study sought to determine which of these three muscles contributes the most to eccentric hamstring strength. Recognizing the correlation between muscle volume and muscle strength, this study compared maximal eccentric hamstring strength with the proportion of each isolated hamstring muscle's volume relative to the total hamstring muscle group volume. Doing so would identify which specific muscle contributes the most to eccentric hamstring strength. This study incorporated 74 male, collegiate football players representing all positions on the team. Maximal strength was assessed through Nordic hamstring curls and overall muscle volume was quantified using magnetic resonance imaging (MRI). Our results show no correlation (R^2<0.2) between maximal force output and proportional muscle volume for the ST, and the BFSH. Additionally, the correlations for these muscles were not statistically significant (P>0.05). The SM muscles had a weak negative correlation (R^2= -0.25) with eccentric hamstring strength that was statistically significant (P = 0.03). The BFLH proportional volume was positively weakly correlated (R^2= 0.22) with eccentric hamstring strength. This correlation was statistically non-significant (P = 0.06). This information shows that no hamstring muscle contributes more to eccentric hamstring strength than any other. Knowledge of this can be invaluable for clinicians and researchers to design comprehensive strength training programs that enhance the collective strength of the entire hamstring muscle group, ultimately optimizing the performance of football players.

There is relatively little research examining the effect of intermittent fasting on hunger and appetite. The existing literature suggests a complex interaction between hormonal signals, subjective hunger, and actual eating behavior. Development of effective and sustainable protocols rests on understanding these relationships. Dietary protocols that involve continuous energy restriction have been shown to increase appetite. As intermittent energy restriction results from fasting protocols, there is reason to suspect that fasting may similarly impact hunger and eating behavior. However, some research suggests that ketogenic or very low energy diets may decrease hunger, making it unclear what the effects of fasting may be. Levels of ghrelin, the primary hunger hormone, typically increase over the course of a fast, whereas satiety hormones, like leptin, decrease. However, these hormonal changes do not always align with ratings of subjective hunger. There is some evidence that the post-fast meal may play a role in hunger and appetite. Different macronutrients have been shown to impact hormones, hunger, and satiety differently. Our study aims to determine how ending a fast with a high or low carb shake will influence hunger and satiety hormones and subjective hunger.

American College of Sports Medicine has again found that wearable technology and resistance training (RT) are two of the top 5 fitness trends in 2023. Our lab recently found that the bicep-worn Polar Verity device was valid and reliable for measuring average and maximal heart rate (HR) during light intensity circuit RT. However, no study has examined other bicep worn devices during RT while also examining heavier intensities. PURPOSE: To determine the concurrent validity of identical Polar OH1 (x2) and Verity Sense (x2) bicep-worn devices in recording average and maximal HR following moderately heavy RT. METHODS: Twenty-one adult participants completed this study (n=10 female, n=11 male; age: 26.1±9.2 yrs; height: 171.3±9.4 cm; mass: 71.4±18.2 kg; RT experience: 5.7±4.9 yrs). The four bicep devices (Polar OH1 x2 and Polar Verity Sense x2) were worn along with the Polar H10 chest strap, criterion for HR. Participants completed 8 supersets of the reverse lunge and shoulder press exercises using dumbbells at a light (4 sets) and moderately heavy (4 sets) intensity with 1 superset of 6 repetitions per exercise (12 repetitions per superset) and 1 min rest between supersets. Data was analyzed for validity (Mean Absolute Percent Error [MAPE] and Lin’s Concordance Coefficient [CCC]), with predetermined thresholds of MAPE<10% and CCC>0.70. Paired t-tests were used to determine differences (p<0.05). RESULTS: For average or maximal HR, neither the Polar Verity Sense 1 (127.2±17.8 or 151.5±16.7bpm) or 2 (125.7±18.8 or 147.9±18.9bpm) or the Polar OH1 1 (128.7±18.5 or 154.5±18.1bpm) or 2 (129.5±18.2 or 156.4±17.4bpm) were significantly (p range: 0.14-0.97) different than the criterion (128.6±19.2 or 149.3±18.0bpm). However, the Polar Verity 1 and 2 were not considered valid for average HR (MAPE range:16.17-17.57%; CCC range: 0.07-0.13) or maximal HR (MAPE range: 11.60-13.33%; CCC range: 0.02-0.29). The Polar OH1 1 and 2 devices were not considered valid, either, for average HR (MAPE range: 17.22-17.25%; CCC range: 0.08-0.09) or maximal HR (MAPE range: 13.24-13.92%; CCC range: .024-0.27). CONCLUSION: Despite our lab previously finding the Polar Verity as valid for HR measurements during light intensity RT, the current bicep-worn devices should not be utilized during heavier intensity RT for accurate HR measurements. Individuals resistance training and utilizing bicep-worn devices for heart rate should use them cautiously.

Systemic Lupus Erythematosus is an autoimmune disease that produces autoantibodies affecting various body regions, including skin, joints, kidneys, brain, aerosol surfaces, blood vessels, etc., resulting in damaging organs and tissue. Patients commonly experience an elevated risk of bleeding or blood clotting, joint stiffness, pain, fatigue, and depression.Our study involved the collection of RNA seq data of B cells of both SLE patients and healthy people from the National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) database. Subsequently, we employed the Automated Reproducible MOdular Workflow for preprocessing and differential analysis of RNA-seq data (ARMOR) workflow. The differentially expressed genes identified by ARMOR were then analyzed using SPIA (Signaling Pathway Impact Analysis) algorithm to find the pathways associated with lupus. We further utilized the Pathways2Targets algorithm to predict potential lupus treatments based on known protein-drug interactions.In our study on lupus patients, analysis using ARMOR, SPIA, and Pathways2Targets identified 10,000 differentially expressed genes and revealed their modulated pathways, providing insights into molecular cascades in lupus. Furthermore, we identified potential drug targets, finding the way for therapeutic interventions that ultimately led to the discovery of new drug treatments. We anticipate that our findings could be utilized for the benefit of lupus patients, further advancing personalized medicine strategies, holding promise for improving the quality of life for individuals grappling with this complex autoimmune disorder.

Hamstring injuries are one of the most common injuries sustained in professional football with 800+ hamstring injuries per year. These hamstring injuries often occur between late swing (eccentric contraction) and early ground contact.PURPOSE: To investigate the correlation of eccentric hamstring strength to muscle volume across positional groups.METHODS:Athletes were divided into three homogeneous groups based on position (big (e.g., linemen), skill (e.g., receivers), combo (e.g., linebackers)). Seventy-three NCAA Division I football players participated (24 big, 37 skill, and 12 combo). Hamstring strength was collected for each leg while performing 3 Nordic curls on a Nordbord device. The peak force of each leg was summed for our data analysis. Collective hamstring volume for each athlete was found through MRI. RESULTS:A Pearson’s product correlation demonstrated an overall moderate correlation (r = 0.52, p < 0.0001) between hamstring muscle volume and strength, with skill players demonstrating a strong correlation (r = 0.66, p < 0.0001), combo players demonstrating a moderate correlation (r = 0.49, p < 0.0001), and big players demonstrating a weak correlation (r = 0.39, p < 0.0001). An ANOVA showed no statistically significant difference of hamstring strength between positional groups (p = 0.1074) relative to hamstring volume (p < 0.0001). CONCLUSION:The observed overall moderate correlation between hamstring strength and muscle volume across positional groups indicates that factors outside of muscle volume contribute to muscle strength. Our data also suggests that, regardless of position, hamstring muscle strength was similar when accounting for volume. Muscle volume was the best predictor of strength for the skill group. However, other factors should be considered, such as motor control factors. In the combo and big groups, these additional factors play a larger role.

However, minimal physiological research has been conducted on the two together and none have measured the accuracy of devices measuring repetition counts across exercises. PURPOSE: The purpose of this study was to determine the concurrent validity of four wrist-worn Garmin devices, Instinct (x2), Fenix 6 Pro, and Vivoactive 3, to record repetition counts while performing 4 different exercises during circuit resistance training. METHODS: Twenty participants (n=10 female, n=10 male; age: 23.2  7.7 years) completed this study. Participants completed 4 circuits of 4 exercises (front squat, reverse lunge, push-ups, and shoulder press) using dumbbells at a light intensity with 1 set of 10 repetitions per exercise and 30 seconds rest between exercises and 1-1.5 min rest between circuits. Mean absolute percent error (MAPE, ≤10%) and Lin’s Concordance Coefficient (CCC, ρ≥0.7) were used to validate the device’s repetitions counts in all exercises compared to the criterion reference manual count. Dependent T-tests determined differences (p≤0.05). RESULTS: No devices were considered valid (meeting both the threshold for MAPE and CCC) for measuring repetition counts during front squats (MAPE range: 3.0-18.5% and CCC range: 0.27-0.68, p value range: 0.00-0.94), reverse lunge (MAPE range: 44.5-67.0% and CCC range: 0.19-0.31, p value range: 0.00-0.28), push-ups (MAPE range: 12.5-67.5% and CCC range: 0.10-0.34, p value range: 0.07-0.83), and shoulder press (MAPE range: 18.0-51.0% and CCC range: 0.11-0.43, p value range: 0.00-0.79) exercises. CONCLUSION: The wearable wrist-worn devices were not considered accurate for repetition counts and thus manual counting should be utilized. People who strength train using free weights will need to wait for either improved repetition counting algorithms or increased sensitivity of devices before this measure can be obtained with confidence.

Authors: Joseph Holmes. Mentors: Jared Nielsen. Insitution: Brigham Young University. BACKGROUND Anosognosia is characterized by a stroke victim’s inability to acknowledge their acquired physical deficits. Such patients could believe they can operate their limbs normally even when they cannot. Patients will often attribute other reasons to explain their deficit (unwillingness to move, a sprain, arthritis, etc).Previous research has reported damage from various brain areas, including several fronto-temporal-parietal areas, insula, and subcortical regions. Many studies suggest that the deficit is caused from impaired sensory feedback coupled with spared motor intentions, which involves premotor, sensory-motor regions, basal ganglia, temporal-parietal junction, insular cortex, and prefrontal cortex. The objective of this study is to confirm the involvement of these brain areas. It is also to identify other possible networks that could contribute to the development of AHP. METHODSWe performed a literature review for case studies of patients presenting with anosognosia for hemiplegia (n=17). The majority of cases were attributed to ischemic stroke (n=15) while the others resulted from hemorrhagic stroke. Lesion network mapping analysis was performed on the 17 lesions with a large cohort of healthy control resting-state scans (n=1000). RESULTSThe main regions to which the lesions were functionally connected included the right transverse temporal gyrus (n=17) and the anterior left insula (n=17). It is also important to note that the lesion networks were found to be negatively correlated with a few areas in the prefrontal cortex. CONCLUSIONFurther research should be done to investigate the involvement of specific areas of the prefrontal cortex in AHP. Some regions in the prefrontal cortex may be negatively correlated; however, past research suggests a positive correlation of other prefrontal regions. It is important that clinicians understand the lesion networks of AHP, as it will guide them to treat patients more effectively. Interventions such as transcranial brain stimulation could become more beneficial to patients, as clinicians will know specific areas of the brain to stimulate to mitigate symptoms of AHP.

The aim of this study is to understand how the macronutrient composition of the fast-initiating meal influences glucose regulating hormones in older, sedentary, and abdominally obese adults. Insulin, amylin, and glucagon were measured immediately before and after a 24-hour fast, as well as 48 hours after fast initiation. Understanding these outcomes will inform fasting protocols such as time restricted eating and alternate day fasting, which offer potential long-term health benefits. 16 participants (7 male, 9 female) each completed two 24-hour fasts consuming only water. In random order, one fast began with a high carb shake and the other with a low carb shake of equal calories, volume and fiber density. After each fast, participants lived and ate normally and then returned 24 hours later. Venous blood draws were taken at hours 0, 1, 24, and 48 to monitor levels of insulin, amylin, and glucagon. There was a significant condition by time interaction for insulin (F = 4.08, P < 0.01), amylin (F = 3.34, P = 0.02) and glucagon (F = 7.93, P < 0.01). Insulin (P = 0.02) and amylin (P = 0.01) were higher and glucagon lower (P = 0.05) after consuming the high carbohydrate shake compared to the low carbohydrate shake. There was no difference, however, between conditions for insulin, glucagon or amylin at 0, 24 and 48 hours.

Authors: Alex Jarvis, Brooklyn Flowers, June Oaks, Sadie North. Mentors: Tyson Harmon. Insitution: Brigham Young University. Background: Dual tasks have been found to negatively affect language production for people with and without aphasia (Harmon et al., 2023). For people with aphasia (PWA) specifically, previous research suggests that limited working memory or attentional capacity contributes to their difficulty with language tasks (Harmon et al., 2019; Pompon et al., 2015; King & Karen 1996; Obermeyer et al., 2020). One common situation in which communication occurs within a dual task environment is talking while driving. Investigating how talking while driving impacts spoken language could help us better understand how to facilitate both safer driving behaviors and improved communication among friends and family while driving. Longer-term, this understanding can springboard further research addressing assessment and intervention practices in aphasia, which better reflect communication in daily life. Original findings related to speech acoustics revealed that talking while driving led to increased speech intensity and decreased speech time ratios (Glenn, 2017; Simmons, 2016). The potential impact of these driving tasks on spoken language, however, has not been investigated. For the present study, we will conduct a secondary analysis of language samples produced across the aforementioned conditions to understand how they impact spoken language production. Method: Data for the present study was collected for a larger project with initial aims of investigating the impact of driving on speech acoustics (e.g., frequency, intensity). This project also investigated bidirectional interference between speech acoustics and driving as well as the effects of different conversational modalities (e.g., talking on the phone, in person, or through Bluetooth). Forty healthy adults who reported no speech, language, or hearing impairment participated in the study. Participants completed seven tasks, which were presented in a random order: driving without speaking, speaking on a hand-held cell phone, speaking on a hands-free phone, talking to a person next to them speaking on a hand-held cell phone while driving, speaking on a hands-free phone while driving, and talking to a person next to them while driving. Within each of these conditions, participants discussed a topic they selected from a list while completing these tasks. To analyze spoken language, we will first transcribe samples orthographically. These transcriptions will then be coded for lexical-phonological, morphosyntactic, and macro-linguistic errors. Parametric statistical analysis will be used to compare across different age groups. Anticipated Results: We hypothesize that participants will demonstrate increased errors in conditions that involve talking while driving (i.e., dual task conditions) than in conditions that involve talking alone (i.e., single task conditions). Previous research suggests dual-tasking has a negative effect on language including lexical and phonological errors even in non-aphasic participants (Harmon et al., 2023). In this study, we would expect more lexical-phonological (e.g., fillers, revisions, repetitions) and macro-linguistic (e.g., aposiopesis) errors during dual task conditions. For future studies involving PWA’s, we would expect more impaired language in dual-task activities than those without aphasia.

Climbing (sport and bouldering) has become a very popular hobby for people all over the globe.Now that climbing is an Olympic sport the need for understanding best training practices through evidence, not anecdotal experience, has grown. Using the International Rock Climbing Research Association (IRCRA) individual grading scale based on route completion difficulty,some research has shown that upper limb strength is important for individuals to progress from recreational/intermediate to more advanced/elite levels. However, many studies use non-sportspecific measurements (i.e., hand dynamometer versus a finger climbing hold) and none have assessed rate of force development (RFD) or lower body strength contributions. PURPOSE: To test the hypothesis that compared to recreational/intermediate climbers advanced climbers would have greater dominant and non-dominant upper-body strength and finger RFD as well as lower body compound strength. METHODS: Nineteen subjects (n=8 female and n=11 male;age: 24.7±7.5 yrs; height: 177.6±7.8 cm; mass: 76.0±14.9 kg; IRCRA Sport Grade: 14.1±6.7; n=10 intermediate, n=9 advanced) completed this study. During a single session, following a standardized 3-5 min. warm-up all participants dominant and non-dominant finger strength andRFD (using a Tindeq dynamometer load cell attached via static rope to a 20mm edge) as well as shoulder strength (using the same Tindeq load cell with a static rope attached to an olympic ring), and lower-body compound strength (isometric mid-thigh pull using G-strengthdynamometer load cell attached to a straight bar with a static rope) were assessed. Three trials were done on each measurement with 1 min. between trials and 3-5 min. between tests. Unpaired t-tests determined differences, p<0.05. RESULTS: Across every measurementadvanced climbers had significantly (p<0.05) higher values for absolute and relative (normalized to body weight, BW) measurements. As absolute and non-dominant results were similar we onlyreport dominant relative results, where appropriate. Indeed, compared to intermediate climbers advanced climbers had significantly higher relative dominant finger RFD (9.9±3.7 vs 20.8±9.4N/s*BW -1 ), finger strength (0.5±0.1 vs 0.7±0.3 kg/BW), shoulder strength (0.7±0.2 vs 0.9±0.2 kg/BW), as well as relative compound strength (1.8±0.4 vs 2.6±0.7 kg/BW, respectively). CONCLUSION: Advanced climbers have larger absolute and relative RFD in their fingers,stronger dominant and non-dominant fingers and shoulders, as well as stronger lower body compound strength. Thus, individuals looking to progress from recreational/intermediate climbing grades to advanced/elite should focus on improving total body absolute and relative strength as well as finger RFD.

This literature review specifically examines different studies and academic journals that have studied the relationship between oral health, obesity, heart disease, and diabetes. Obesity is linked to the patient's oral health in many ways. When patients are consuming large quantities of food more often than normal, this results in a more acidic environment along with energy for bacteria to grow. One study found a correlation between obesity and risk factors such as “frequency of brushing teeth, smoking, tooth loss, gingivitis, and dental caries (Yilmax & Somay, 2021). This article discusses the strong correlation between oral health and heart disease. Several studies emphasize the importance of dental hygienists educating their patients about the link between their oral and cardiovascular health. The articles conclude that treating periodontal disease more effectively and aggressively could lead to a marked reduction in coronary heart disease rates and vice versa.Diabetes and periodontal disease is also examined at length in this literature review. Diabetes and periodontitis is described as a ‘two-way relationship’. Evidence shows that individuals with diabetes, type 1 or type 2, are 34% more likely to develop periodontal disease. On the other hand, individuals experiencing periodontal disease are 53% more likely to develop diabetes (Wu, et al., 2020). This literature review will explore the importance of oral health in keeping your entire body healthy.ReferencesArora, A., Rana, K., Manohar, N., Li, L., Bhole, S., & Chimoriya, R. (2022).

Authors: Danielle Terry, Seth Helton, Michael Creer. Mentors: Austin M Green. Insitution: University of Utah. With anthropogenic influence increasing worldwide, it is important to understand how wildlife behavior changes in response to urbanized landscapes. Urban ecosystems represent relatively novel landscapes with unique threats and opportunities that can completely restructure species’ population composition and dynamics. Mule deer (Odocoileus hemionus) have been shown to alter their temporal activity in response to urbanization across their range of the Intermountain West of the United States. In this study, we will investigate the effects of anthropogenic influence on mule deer temporal activity behavior across two distinct life stages: fawning and non-fawning. Data for this study will come from the citizen science camera trapping project, Wasatch Wildlife Watch. The full project area is separated into two study sites: “Rural” and “Urban”. This study will be based around the wild-to-urban interface of the Central Wasatch Mountain Range and the Bear River Mountain Range, which composes some of the most highly recreated portions of the Uinta-Wasatch-Cache National Forest, receiving approximately 9,000,000 visitors annually (U.S Forest Service). We will investigate the proposed differential effects of anthropogenic influence and urbanization on mule deer diel activity patterns in the fawning vs. non-fawning life stages. Also, we will inquire whether intraspecific responses in mule deer diel activity alter interspecific interactions, especially with fawning predators, and how these responses might interact with environmental factors. We predict that anthropogenic influence and urbanization alter the diel activity patterns of fawning mule deer more than non-fawning deer and that the presence and activity of fawn predators (e.g., coyote [Canis latrans]) would have a stronger effect on fawning deer activity than non-fawning deer activity.

The purpose of this paper is to qualify and analyze the leading driving forces in determining the success of healthcare innovations in a variety of subspaces in the healthcare industry. Health is one of the largest markets in America and is almost universally relied upon. As the systems and technologies of healthcare are innovated and improved upon, the quality and efficiency of this care stands to increase, potentially benefiting both those who provide care, those who receive care, or both. The healthcare industry offers a plethora of niches needing innovating and the potential of high economic return for the producers, and yet only a small portion of innovations are adopted and successfully integrated with some areas having a failure rate approaching or exceeding 90% (Sun et al., 2022)(Jacobs et. al, 2015). What propels these few successful innovations towards adoption that so many other innovations fail to achieve? Through the analysis of dozens of papers researching success robustness in various healthcare fields, such as pharmacology and technological innovation, we will summarize the data in search of shared commonalities among successful innovations.

Maternal mortality, also known as maternal death, is defined as the death of a woman during pregnancy and up to one year postpartum. (MacDorman et al., 2021; Spelke & Werner, 2018). The United States is the only developed nation where the rates of maternal mortality are rising, and they have been rising for twenty years (Simpson, 2019; Spelke & Werner, 2018). This incidence represents a maternal health crisis in the United States. On average, 700 women in the United States die each year from pregnancy-related complications. This equates to 17.2 maternal deaths for every 100,000 live births (Simpson, 2019). Currently, the maternal mortality rate for Utah is higher than the national average at 21.5 maternal deaths per 100,000 live births (Utah Department of Health and Human Services, 2023). According to More than 60% of these deaths are preventable (MacDorman et al., 2021; Simpson, 2019).The leading causes of maternal death in the United States are hemorrhage, preeclampsia, eclampsia, hypertension, embolisms, and cardiomyopathy, which often lead to cardiovascular disorders (MacDorman et al., 2021; Simpson, 2019). The Utah Health and Human Services (2023) reported that increases in heart disease, hypertension, diabetes, mental health disorders, and other chronic conditions complicate pregnancies and are contributing to maternal mortality in Utah. The American Heart Association has cautioned that pregnancy complications like preeclampsia, gestational diabetes, and preterm delivery are linked to maternal heart disease later in life (Parikh et al., 2021). Research suggests that each episode has a cumulative effect (Marill, 2021), meaning, the more pregnancies women have, and the more complications women have during pregnancy, the more elevated their risks are in general for cardiovascular disorders as they age. A qualitative survey was sent out using snowball sampling to women over the age of 18 in Utah asking about their understanding of cardiovascular risk factors and current health conditions. Findings showed that women were unaware of their potential cardiovascular risks associated with pregnancy. Raising awareness regarding these cardiovascular risks may be the number one preventative strategy, as women are the ones who bear the personal and physical risks. If pregnant women are aware of their cardiovascular risk factors, they can be empowered to raise concerns when necessary. Future interventions may include educating all women of childbearing years about cardiovascular risks prior to pregnancy, as well as more frequent screening of women during and after delivery (Marill, 2021).

The pro-opiomelanocortin (POMC) gene is expressed in the hypothalamus and pituitary and is cleaved into several peptide hormones. One of these is melanocyte-stimulating hormone (MSH), which is involved in food intake and energy expenditure. A mutation in the POMC gene can result in a rare condition in which the subject displays early-onset obesity characterized by severe hyperphagia (i.e. excess hunger). Affected subjects may also show a lack of pubertal development. In this experiment, we will study mice with a mutation in the POMC gene. They show some of the same symptoms as humans with a POMC mutation, including hyperphagia, obesity & infertility. Specifically, we will investigate the estrous cycle in female mice to determine if they are cycling normally. The estrous cycle, similar to the menstrual cycle in humans, is characterized by changes in reproductive hormones, and can be divided into four stages: proestrus, estrus, metestrus, and diestrus. Cells lining the surface of the vagina have been previously collected using a pipette smear technique. Each stage can be characterized by the proportion of three cell types: epithelial cells, cornified cells, and leukocytes. These cells correspond to the fluctuating hormone levels during the estrous cycle. Images of these samples will be assessed for the composition of cells to determine the stage of the estrus cycle, and whether or not the cycle displays normal patterning. Because POMC-deficient mice are infertile, we hypothesize their estrous cycles may be atypical. For example, the estrous cycle of the POMC-deficient mice may appear in irregular order or with one stage being predominant over the rest. If the estrous cycle is atypical, then we will measure the hormones directly to confirm that the infertility is caused by changes in hormonal regulation. This will help us to understand more about how the POMC gene affects reproductive function.

Multiple Myeloma (MM) is a malignancy of plasma cells and one of the more common hematological malignancies (6.3/100,000 new cases/year). Although treatments have improved, most patients fail their first line of treatment and ultimately do not survive beyond 5 years. Identifying patients at high risk of failing treatment early is a critical need. SPECTRA is a statistical technique developed by the Camp Lab to characterize global gene expression (the transcriptome) by representing it as multiple quantitative tumor variables. Spectra variables allow gene expression to be incorporated into predictive modeling to identify high-risk groups.Transcriptome data for myeloma cells was available from 768 patients in the international CoMMpass study where 39 spectra variables were derived. Each patient has a value for each of the 39 variables (their spectra “barcode”); patients can be compared for each bar in the barcode. Predictive modeling using spectra variables was successful in identifying risk groups for time to treatment failure, such that a patient’s tumor transcriptome can be used to predict whether they are at high risk of having their treatment fail earlier.To replicate the CoMMpass data findings, we collect and process local biological samples from MM patients at the Huntsman Cancer Institute (HCI). We collect bone marrow samples, which are then cell-sorted to identify tumor (CD138+) cells. RNA is extracted from these cells and sequenced to generate transcriptome data. Then the spectra barcode is calculated.Utilizing the SPECTRA technique provides a more complete understanding of MM by better characterizing the tumor. Each spectra is a tumor characteristic. Our future research includes an investigation of whether inherited variations (in normal DNA from saliva or whole blood) are associated with the transcriptome risk score. We are also pursuing the SPECTRA technique in several other cancers.

The number of rocket launches per year has been increasing dramatically since 2015, with more rockets launched in the year 2022 than had ever been launched. With the increase in the number of launches per year, it has become increasingly important to understand the impact of rocket launches on the greater environment and community. One important aspect of a rocket launch is the level of acoustical energy that is produced during liftoff. Instantaneous pressure values have been regularly recorded up to 180 dB. Due to these high levels, it’s become important to be able to accurately predict the noise produced by a rocket. One powerful tool used in predicting this sound is the crest factor. The crest factor is an acoustical measurement that shows the difference between the maximum sound pressure (i.e. the crest) compared against the averaged value of the sound pressure. Additionally, this information is vital for planning acoustical equipment in order to avoid measurement clipping. This presentation will be about crest factor analyses performed on the Antares NG-19 rocket launch from August 2023.

Authors: Sofia Denise Flowers. Mentors: Lauri Linder. Insitution: University of Utah. Background and Purpose: In the year 2023, roughly 9,000 children will be diagnosed with cancer each year in the United States. Dealing with a potentially fatal diagnosis is already difficult for many grown adults, let alone a young child. The aim of this project is to describe caregiving experiences of parents and children with cancer as related through feedback comments within written and oral feedback to proposed items to measure self-efficacy for managing their child’s symptoms and behaviors used to manage their child’s symptoms.Methods: This project involved a secondary analysis of qualitative data from 21 parents (19 mothers; mean age 38 years) of school-age children with cancer who participated in a study to establish the content validity of instruments to measure aspects of symptom management. Data consisted of interview transcripts and free responses to the content review surveys. The data were then uploaded to Dedoose. My mentor and I worked independently to identify statements pertaining to parents’ experiences in managing their child’s symptoms and responding to the child’s cancer diagnosis. We then met together to reconcile content and then organize parents’ statements into categories and subcategories. Results: 101 excerpts were extracted from the transcripts and included for the secondary analysis. Excerpts were grouped into four main categories: informational resources, social support, emotional support, and medication management Within these four main categories, subthemes of professional staff support, managing child attitude and mood changes, and balancing between being a parent and their child’s medical advocate were present. Conclusion: The insights gained from this project can guide the information healthcare providers need to provide better care to the child and additional support to parents. This can allow professional staff to get a stronger understanding of not just the family’s medical needs but their informational, social, and emotional needs as well.

In this research project, we have transformed an existing Raman spectroscopy simulation, enhancing its performance and capabilities through the integration of parallel computing with GPU acceleration. This significant improvement in computation time allows us to break through previous computational limitations, enabling more sophisticated and complex applications of the simulation. The principal applications we will be assessing are the viability and potential of spatially offset Raman spectroscopy (SORS) for deeper tissue analysis, exploring the possibilities of topographical imaging using Raman techniques, and the advanced application of chemical imaging of microscopic tumors. This expanded scope demonstrates the simulation's potential in early cancer detection.

Diabetes Mellitus is a chronic disease characterized by a loss of functional beta cell mass, and impaired glucose homeostasis. Elevated glucose levels in the body are known to be the cause of a plethora of debilitating illnesses. Hyperglycemia negatively effects beta cell function, resulting in impaired insulin secretion and cell death. Two key transcription factors involved in beta cell development, function, and proliferation are Nkx6.1 and Pdx1. We have shown a binding interaction between these Nkx6.1 and Pdx1 and have shown that they co-regulate various genes necessary for beta cell maturity and function. Preliminary data indicate that elevated glucose concentrations downregulate Nkx6.1 mRNA and protein, as well as Pdx1 mRNA. However, the effect of elevated glucose concentrations on Pdx1 and Nkx6.1 binding interaction and subsequent function remains largely unexplored. Here we demonstrate the effect of hyperglycemia on the Pdx1-Nkx6.1 interaction, and the effect on expression of Pdx1 and Nkx6.1 downstream target genes. Understanding the effect of hyperglycemia on this interaction will allow us to better understand the stress that a beta cell is under during diabetic conditions, and to develop interventions to ameliorate these effects.

Changes in health insurance due to the Affordable Care act created a bridge for college students to remain on their parent or guardian’s health insurance for a longer period of time. However, little is done to close the gap of education deficiency in the area of health insurance literacy during this time. While most students in a universal health system have relatively few options to choose from, students in the US are faced with many different plans through employment or the open marketplace. Therefore, in order to ensure adequate access to care, it is imperative that students understand the fundamentals of this system in the US. This quantitative cross-sectional survey sampled 500 currently registered UVU students to assess their knowledge, attitudes, beliefs and healthcare utilization. This data was stratified by age and sex. Descriptive statistics and chi2 analyses were performed. This study showed that disparities in healthcare literacy affect healthcare utilization and can be a catalyst for long-term healthcare access issues for students and their families.

Introduction: It is vital that patients are adequately prepared for surgical intervention. To meet this need, many medical centers have adopted prehabilitation protocols. The aim of this study was to establish an in-depth comprehension of the attitudes towards surgery and barriersand preferences to prehabilitation for patients identifying as Latino, in order to develop a preliminary framework for adapting prehab programs to best meet the needs of this specific patient population.Methods: We conducted qualitative semi-structured in-person one-on-one interviews with Latino patients who had recently undergone major abdominal surgery. The interviews, conducted at an academic medical center, were audio-recorded, transcribed verbatim, translated into English (as needed), iteratively coded, and discussed by four researchers to reach consensus. We used thematic analysis to identify shared attitudes held by patients and common barriers to the adoption of prehabilitation programs. Analysis of these attitudes and barriers, along with stated patient preferences, led to the development of several ideas that physicians can implement to increase prehab adoption among Latino patients.Results: We interviewed 16 patients, at which point we reached thematic saturation. The patients were on average 52 years old (range 20 to 79) and 50% were women. Our pooled kappa score was .92, indicating a very high degree of concordance among the coding researchers. We identified five common attitudes held by Latino patients regarding surgery: anxiety associated with hospitalizations and surgical procedures, deep trust in physicians, reliance on positivity, tight-knit families/communities, and prominent religious and cultural beliefs. A lack of understanding, physical limitations, a reactive/delayed approach to healthcare, dietary barriers, and mental barriers emerged as obstacles to prehabilitation adoption. These attitudes and barriers, along with direct patient feedback, led us to identify several programmatic priorities that may increase adherence to prehab. These components consist of face-to-face interaction, increased communication, patient and physician collaboration in program development, and family/support group engagement in surgical preparation.Conclusion: Our study provides physicians preliminary insight into customizing prehabilitation programs to best meet the needs and customs of the Latino community, including anxiety associated with hospitalizations, strong social support, and a dominant role of religious faith in coping with illness. We identified several critical components that may make prehab more culturally competent and thus more likely to be adopted by patients. These include in-person coaching, increased information about the upcoming operation and recovery, and engagement of family members. We recommend that healthcare teams committed to prehabilitation consider these needs to make their programs more attractive and accessible to their Latino patients.

The genes are expressed in the prostate gland. Both genes have several polymorphisms. Here we examine the association of rs4648298 (A-G transition) and rs20417 (G-C transversion) polymorphisms and prostatic diseases. This research was approved by the Utah Valley University IRB.Materials and Methods: DNA was extracted from a blood sample of 56 healthy volunteers, 51 volunteers with benign prostate hyperplasia (BPH), and 61 volunteers with clinical prostate cancer (PCa). Genotyping was conducted through PCR-RFLP analyses. The restriction enzymes used were BaeGI (for rs4648298) and AciI (rs20417), respectively. Alleles with the restriction site were considered recessive. The association was inferred through statistical analyses of the distribution of the genotypes (BB, Bb, and bb or AA, Aa and aa), and allele frequencies among the controls and the affected groups. A p-value of ≤0.05 was considered significant.Results: The distribution of the genotypes is in Hardy-Weinberg equilibrium for all three groups. The b allele of the COX-1 gene is extremely rare (less than 3%), and no significant association between the B or b allele or BB, Bb, and bb genotypes and prostatic disease was observed. The a allele of the COX-2 gene is more common in the BPH group (p=0.011), but not the PCa group (p= 0.472) or the combined affected group (p=0.068) compared to the control group.Conclusions: There is no association between the rs4648298 polymorphisms of the COX-1 gene and prostatic diseases. The a allele of the rs20417 polymorphisms of the COX-2 gene is associated with higher risks of BPH and possibly PCa. The small sample size, sampling from one ethnic group, and the low distribution of the b allele in the Lebanese population are limitations of this study.

Authors: Tayler Fearn, Caroline Torgensen, Vern Hart. Mentors: Vern Hart. Insitution: Utah Valley University. Coherent diffraction imaging (CDI) is a newly developed modality used to measure phase shifts introduced by fine-scale structures in cells. These phase shifts can be used to distinguish healthy and malignant cells, providing a diagnostic marker for early cancer detection. However, this process, in which diffracted light interferes with incident light, requires collecting scattered photons at large angles, representing high spatial frequencies and short wavelengths. The highest frequencies, needed to reconstruct small details in cells for improved image quality, occur at distances of several centimeters from the central bright fringe. As such, these signals are faint and difficult to collect experimentally. We propose the use of deep learning to synthetically extrapolate diffraction patterns at large distances, where measurements are difficult. In prototyping this method, we will present results produced by a generative adversarial network (GAN), trained using existing data of watercolor paintings to preform style transfer and image extrapolation. This will be an essential step in working towards the larger goal of developing GAN’s that can accurately extrapolate diffraction images.

As the world’s human population continues to concentrate within urban areas and these landscapes continue to expand worldwide, wildlife is under pressure to adapt to novel environmental disturbances. Along urban-wildlife gradients, and especially within less developed areas, human recreation can affect wildlife behavior. These effects may be most apparent during peaks in human recreational activity. In addition, climatic conditions such as aridity and precipitation can also alter wildlife behavior. Understanding the interactions between these two pressures, human activity and climate, can help us understand how wildlife behavior will be affected as human populations grow and climate warms. In this study, we will use data from a large-scale citizen science camera trapping project to assess whether periodic increases in human recreational activity paired with arid climates will elicit behavioral responses across multiple mammal species in northern Utah, U.S.A. Specifically, we will assess whether increases in human recreational activity during the weekend affected mammalian temporal activity patterns at the community-wide and species-specific level, taking into consideration if these trends are amplified in areas that are arid and low in precipitation. I hypothesize that increased human recreational activity will alter wildlife behavior, in general, however this change in behavior will be amplified in drier, hotter areas. I predict that during the weekends human activity will increase, leading to general decreases in activity, mobility, and breeding behavior across species, and this will be amplified in hotter and less vegetated areas. However, I predict that naturally diurnal species will be more affected than nocturnal species as they attempt to avoid overlap with humans, leading to changes in species-species interactions.

Utah Lake is the third-largest freshwater body west of the Mississippi River and serves as a vital resource for just over 600,000 Utah Valley residents through agriculture, residential and recreational purposes. In addition to its utility, Utah Lake provides a haven for biodiversity for numerous species within its wetlands. Despite its utility and importance, the lake faces two significant challenges in the form of Trace Metal (TM) pollution and the encroachment of invasive plant species known as Phragmites australis (P. australis). Despite considerable investments of time, money, and resources by various state agencies to address these concerns, their success has been limited due to the agency’s isolated efforts for these large multifaceted issues. TM, though naturally occurring in the environment, has been found to be toxic to both people and the ecosystem when at elevated levels. P. australis, is a robust and fast-growing macrophyte, possessing remarkable adaptability to and tolerance for poor soils, enabling it to rapidly outcompete native species. Due to P. australis resilience and aggressive nature, many colonies have grown around the lake regardless of soil conditions. Studies have shown that P. australis has been utilized for remediation purposes around water bodies by extracting TMs from sediment. While P. australis must be addressed, can it be used as part of the solution by identifying TM polluted areas? This study aims to discern the variety in TM absorption by P. australis in both unpolluted and polluted sites in the wetlands surrounding the hyper-eutrophic Utah Lake. We selected nine sites around Utah Lake, considering their land use and proximity to pollution sources. At each site, three replicate samples encompassing P. australis, soil, and water were collected. These samples underwent a meticulous process, including washing, weighing, grounding, sieving, acid digesting using a CEM MARS 6, and analysis for TM content within an ICP-MS. Our preliminary findings reveal that in both unpolluted and polluted sites, soil concentrations of As and Cd exceeded background levels (11.73, 1.53 in unpolluted sites, and 27.47, 6.63 in polluted sites, respectively). Notably, in select polluted sites, such as UVU, P. australis displayed a remarkable capacity to hyper-accumulate As, with a transfer factor of 167.14% compared to the lowest unpolluted sites, like Lindon, which showed a rate of about 10%. Across all sites, the accumulation of Cr was relatively consistent (ranging from 17.13 to 19.7 ppm), irrespective of biomass. The examination of TM concentrations, transfer factor rates, and TM accumulation based on biomass suggests that P. australis may serve as a valuable biomarker for identifying TM-polluted sites. This research holds significant relevance, as it could offer state agencies a swift and effective means to pinpoint TM-polluted areas. Moreover, the areas where P. australis is thriving may be leveraged for phytoremediation efforts in TM-contaminated sites, providing an environmentally friendly solution to address this pressing concern.

Authors: Drew Allred, Vern Hart. Mentors: Vern Hart. Insitution: Utah Valley University. Surgery remains one of the most common and effective treatments for a variety of cancers, especially those that form solid, localized tumors such as breast and colorectal cancers. During these treatments, the palpable lesion is surgically resected with the assumption that cancerous cells have metastasized to nearby tissues. As such, surgeons will excise a tissue margin surrounding the tumor in hopes of removing any additional cancer, thus preventing further spread of the disease. However, this process is time-consuming and requires specialized expertise from a trained pathologist to verify that all cancer has been removed. Furthermore, if the pathology report indicates that not all cancerous cells have been extracted, additional follow-up visits and surgeries are typically required. In recent years a number of non-invasive technologies have been developed which seek to map cancerous cells in whole tissues. Training and validating these methods still requires a reliable ground truth, typically provided by an annotated pathology report. We propose a simpler model in which two cell species were co-cultured to provide a heterogeneous training sample. One of these species (PANC-1) was transfected with a vector coding for a fluorescent marker to represent healthy tissue, while the other species (COS-7) remained untreated, representing cancerous cells. An experiment was then conducted using a coherent diffraction imaging (CDI) system, in which laser light incident on the cells was used to quantify phase shifts produced by each cell type. Fluorescent microscopy was then used to create a map of transfected and non-transfected cells for comparison. Results will be presented demonstrating a correlation between the phase shifts produced by the two cell types and the corresponding fluorescent images, potentially facilitating optical cell identification without the need for pathology.

How reliable is emotional facial expression coding within and across raters? Background Emotion, described as “physiological forces, located within individuals, that bolster our sense of uniqueness....” (Katriel, 2015, p. 57) is a critical aspect of day-to-day communication. For people with acquired language disorders post-stroke (i.e., aphasia), this interaction is particularly important due to relatively spared emotional processing, which has the potential to either facilitate or interfere with language processing (see e.g., Harmon et al., 2022; Ramsberger, 1996). The present study is part of a larger project, which seeks to determine whether people with aphasia exhibit more emotional facial expressions during personal narrative discourse than adults who do not have aphasia and whether these expressions are more emotionally arousing. The present study specifically seeks to investigate the reliability of facial coding by comparing average frequency and intensity of emotional facial expressions both within and across undergraduate student coders. Methods In order to quantify emotional facial expression frequency and intensity, undergraduate research assistants are trained to code facial expressions using a modified FACES protocol (Kring and Sloan, 2007). The modified protocol will be used to code emotional facial expressions of video footage that was obtained from participants while they told personal narratives (e.g., talking about an illness they experienced or an important life event). First, research assistants identify the baseline facial expression for each participant. Next, research assistants code transitions from a neutral expression to an emotional facial expression for valence (positive/negative) and intensity. Intensity ratings are scaled from 1 to 4 depending on how many units of the face are involved within the corresponding facial expression. Using this protocol, research assistants will begin facial coding after they are trained and demonstrate mastery by attaining 80% agreement with a master code. Upon completing initial data coding, research assistants will be assigned to recode 10% of previously completed video samples as well as 10% of samples that were previously coded by other coders. This secondary coding will be used to measure intra- and inter-rater reliability across dependent variables: frequency of emotional facial expressions, intensity of positive facial expressions, and intensity of negative facial expressions. Average frequency of emotional facial expressions will be calculated as the number of facial expressions produced per minute within a given sample. Intensity of positive and negative facial expressions will be calculated as the mean intensity within each valence respectively. The average frequency and intensity of initial and reliability codes will then be compared using Pearson’s correlation coefficient. Anticipated Results We anticipate that intra- and inter-rater reliability will be above 0.8. Through a strict training process, research assistants will calibrate their coding to achieve 80% agreement with the master code. We anticipate this training process to produce effective intra- and inter-rater reliability. Findings will be important for determining the reliability of facial coding procedures and trustworthiness of data for answering questions related to the longer-term project.

Attorneys play an important role in protecting the rights of the defendant and maintaining fair courtroom outcomes. This project compared self-reported fairness between court customers with and without an attorney representing their case. 372 Provo City Justice Court customers reported their perceived fairness in a 10-item survey, validated by national court assessment tools. Statistical analysis was performed, and a linear regression model revealed no association between legal representation and fairness. This indicates that both groups reported the same level of fairness, regardless of attorney representation. While evidence suggests that court customers with an attorney may receive better outcomes and less jail time, this was not reflected in court customers’ perceived fairness. We suggest a court navigator be available to court customers, so they can better understand how fairly they are being treated.

The Hyrum Smith Papers project, patterned after the Joseph Smith Papers, is a scholarly initiative at Brigham Young University aimed at collecting, transcribing, analyzing, and publishing selected extant documents associated with Hyrum Smith, the older brother of Joseph Smith, Jr.—key figures in the early history of The Church of Jesus Christ of Latter-day Saints. With a focus on illuminating the often underappreciated contributions of Hyrum Smith, this project examines a wide range of historical documents. These include, but are not limited to, personal correspondence, journals, sermons, certificates, legal documents, land records, ecclesiastical and administrative documents, and others. The purpose is to contribute to a deeper understanding of Hyrum’s role, leadership, and influence within the context of the American religious, social, and political climate of the early 19th century. The goal of this research is to publish a volume with transcriptions, narratives, photographs, and illustrations associated with Hyrum Smith’s life. This UCUR oral presentation will provide an overview of how relevant documents are identified and incorporated into our corpus.

These substances are commonly used in skincare products to prevent the outer layers of the skin from drying out. Humectants also serve a similar purpose in tissue preservation and prevention of decomposition of cadaveric specimens. As there have been few comparative studies analyzing the effects of different chemicals on the preservation of cadaveric tissue, we designed an assay consisting of wet-dry analysis to compare the effects of four common humectants (2-phenoxy ethanol, glycerol, propylene glycol, and ethylene glycol) on water retention in various cadaveric tissues. These tissues include human skin, skeletal muscle, brain, liver, cardiac muscle, and lung tissue. In each experiment, the tissue was submerged in the humectant and then weighed before and after being placed in an incubator. From these values, we calculated the percent difference in tissue mass to determine the most effective humectant concentration for retaining moisture in the tissue. We first tested a concentration gradient for each humectant to determine the most effective concentrations for each humectant. Then we performed a second set of experiments to compare the ideal concentrations of the humectants under the same conditions in each tissue. In our preliminary experiments, we found that glycerol is the most effective in retaining moisture in several of these cadaveric tissues. As we finish our experimentation we plan to create a tissue library to provide an evidence-based standard for wetting solutions used in anatomy labs.
