Can litter removal in urban parks improve water accessibility for bats?

Type: Undergraduate
Author(s): Katherine Davis Biology
Advisor(s): Victoria Bennett Environmental Sciences

Despite bats providing essential ecosystem services, such as pollination, seed dissemination, and pest control, bat populations are facing a global decline due to habitat loss from human activities, including urbanization. We can, however, enhance urban areas to support bat communities by ensuring that suitable resources, such as water, are available and accessible. While availability is associated with the abundance of water sources in an area, accessibility dictates whether bats can physically get to and drink from the surface of a water source. One factor that can influence accessibility is the level of clutter. Clutter represents any physical obstruction present on the surface of the water or in the immediate surrounding area, including vegetation, exposed rock, and debris. Yet, not all forms of clutter are natural. The presence of litter can negatively hinder water accessibility. Thus, in urban areas where litter is more prevalent, a simple litter or trash clean-up scheme could potentially represent an effective restoration activity that community groups could undertake to increase water availability and accessibility for bats in their neighborhoods. To explore this concept, we assessed whether such a community-based clean-up scheme could effectively improve water resource accessibility for bats. For this, we cleared water sources in local parks and neighborhoods of trash monthly during the bat activity season, while conducting behavioral surveys using thermal cameras to determine whether bats drank from these sources. We then compared bat drinking activity recorded at ponds from 2021-2022 prior (i.e., no clean-up) with activity post-clean-up in 2023 to establish if more bats drank. From our results, we hope to inform not only local wildlife conservation programs but also efforts to improve community health.

Blood Flow Restriction Related to Chronic Injury – A Critically Appraised Topic

Type: Graduate
Author(s): Ellie Meyer Interdisciplinary
Advisor(s): Ashlyne Elliott Interdisciplinary

Blood flow restriction (BFR) is a technique that has been gaining popularity in the clinical athletic training setting over the past few years both for rehabilitation and recovery. However, most research and emphasis of BFR research has been on post-surgical patients, especially post-operative anterior cruciate ligament repair, rather than chronic injury, specifically lowerbody. Thiscriticallyappraisedtopic searches the literature to find out what research has been done on chronic injury and if BFR is effective in reducing pain and bettering outcomes for chronic lower body injury. Studies were found through various databases including CINHAL, EBSCOHost, MEDLINE, and PubMed. Initial results yielded 270 studies with inclusion/exclusion criteria based on subject, standard of study, and relevance due to date published narrowed results down to only 2. Research on chronic pathologies and BFR use is limited. More research should be done on this topic to obtain more information and evidence. Six studies were found that passed inclusion and exclusion criteria but only two were suitable for this CAT. Based on inclusion and exclusion criteria, only two articles met all criteria to be used in this CAT. Studies included were quality and studied population groups that could yield quality results. For athletes with chronic injury, BFR can be beneficial for alleviation of their symptoms as well as strengthen the lower extremity to help prevent injury in the future. BFR training should be considered for all patients due to the benefits and efficiency of the technique. The research on chronic patients compared to post- operative patients is limited, but that available is quality and focused.

After-school programs can be highly beneficial to elementary school students. Pickleball With a Purpose is a weekly after-school program founded by TCU students with support from the Experiential Projects to Impact the Community (EPIC) committee. This program works with a local elementary school in Crowley Independent School District (CISD). Pickleball appeals to all ages because it can be picked up relatively quickly, regardless of skill level. As part of the program, pickleball was introduced to 4th and 5th graders at Meadowcreek Elementary by teaching a two-week clinic introducing foundational paddle skills during P.E. classes. Students in the after-school program engage in clinics, drills, and games to further develop their communication skills while fostering connections with mentors from TCU. The EPIC committee's funding and our partnership with the Selkirk Growth Program have allowed us to supply the elementary school with equipment such as nets, balls, and paddles. The purpose of the Meadowcreek Pickleball Club is to provide elementary school students with a safe environment where they can grow as individuals while learning a new sport.

Swimming is a skill that is often assumed to be commonplace. However, in a study from 2017-2021, 411 children fatally drowned in Texas; 32 drownings were from Tarrant County (Texas Child Drowning Statistics). In 2019, 23 Tarrant County drowning deaths were among adults (Drowning in Tarrant County). Two community organizations, The Fort Worth Drowning Prevention and Water Safety Coalition (FWDPC) and the YMCA Fort Worth (YMCA FW), conduct dedicated summer programs to teach children and adults in-water and classroom-based water safety strategies. This grant project supports its community partners by advertising for/providing volunteers, which enables the accommodation of more participants per clinic. In addition, this grant project provided occupational health supplies (sunscreen and sunglasses) to their community partner to mitigate the prolonged sun exposure commonly faced by their volunteers. Through this project, TCU students have engaged with these organizations, supported their objectives, and directly improved drowning statistics within the Fort Worth community.

Location: Basement, Table 4, Position 2, 1:45-3:45

Project Overview:
2020 we partner with Once Upon a Room. We partnered with Cook Children's Hospital to decorate rooms for children who will have an extended stay. Due to COVID-19, we could not continue with Once Upon a Room. In the 2021-2022 we created Bags of Joy and continued to partner with Cook Childrens Hospital. We provided holiday-themed goodie bags as well as welcome hygiene bags.

Background of the Community:
The community in which we are working with those under the age of 18 with poor health.
Our community partner is Anne Stankus and Megan Hodges, Child life specialist at Cook Children

Need Statement:
Our community partners have communicated to us that there is a need for hygiene and essential items for the caregivers of a patient to receive when they are admitted to the hospital, so that they have to opportunity to stay with their child durning this time of need.
Another need that has been expressed to us has been for the hosting of events, like game nights.

Project description:
We had hoped to continue to give hygiene bags and make a switch from goodie bags to hosting a game night.
This year we were to supply 36 welcome bags for Cook, host a game night, and donate 400 easter eggs for their annual easter egg hunt.

Deliverables:
As this was our first year hosting a game night at Cook children, we struggled in the begging to find games and activities that would fit into the guidelines but in the end, we were able to make it a successful event and now we have ideas on ways to improve for next year.
We continue to have good feedback from our Cook Children's coordinator.
As two of our members are graduating we will still have one member who is an active student at TCU. Molly, our non-graduating member, will take over our EPIC grant.

K-12 curricula worldwide typically lack a strong emphasis on alternative energies, particularly solar and wind power. To counter this, the University of Cambridge has developed the “Power your School” initiative, a program where students learn to map their school and local area, predict where the best sites for solar panels may be on their campus, use scientific equipment accurately, record results, and make ideal recommendations based on their data. TCU Chemistry Club and the Coffer Research Lab have partnered with this initiative to help local elementary schools investigate the benefits of renewable energy, assist in calculating the financial benefits of solar panels over a span of multiple years, and most importantly - to help young students learn the basics of proper recording of scientific data. Through poster creation and its subsequent presentation, students also use design and oral communication skills to educate local officials (and beyond) into the benefits of investing in renewable energy. Methods and results of this project will be presented.

The transition from high school to college marks a significant life change and, as a result, could lead to changes in health behaviors, exercise, and stress levels. Physical activity can enhance self-confidence and collectivism, improve emotional states, decrease stress, aid in building relationships, and contributes to feelings of elation and satisfaction (Qu, 2020). Studies show lower levels of activity among college women, with Black women having greater risk of obesity than white women. (Ajibade, 2011). The effects of a lack of physical activity for college minority women pose more significant threats as they increase in age; this is especially notable with Black women, who present low activity levels compared to white and other minority women (Greaney et al., 2017).

4HerHealth aims to combat the prevalence of potential health-related risks by fostering a community that supports physical activity and wellness in minority college students’ lives. The program consists of biweekly activities that highlight various health-related activities such as TCU-instructed fitness classes, step challenges, cooking and nutrition classes, and study and stress-relieving sessions. Participants who expressed low activity levels before the program reported an increased drive to go to the gym and eat healthier. Overall, participants said the program was informative, well-rounded, and provided a safe space and community for minority women on campus.

Location: Third Floor, Table 9, Position 2, 1:45-3:45

Mathematical modeling of viral kinetics can be used to gain further insight into the viral replication cycle and virus-host interactions. However, many of the virus dynamics models do not incorporate the cell-to-cell heterogeneity of virus yield or the time-dependent factor of virus replication. A recent study of vesicular stomatitis virus (VSV) kinetics in single BHK cells determined that both virus production rate and yield of virus particles varies widely between individual cells of the same cell population. Here we use the results of the previously mentioned study to determine the distribution that best describes the time course of viral production within the single cells. We determined a list of eight potential distributions that are commonly used in viral kinetics models to fit to each data set by minimizing the sum of squared residuals. The model of best fit for each individual cell was determined using Akaike’s Information Criterion (AICC ). Results of this study show that the distribution that best describes viral production varies from cell to cell. This finding could have further reaching implications for incorporating time-dependent viral production into a standard model of virus kinetics in order to better reproduce the diversity of viral replication that occurs over time within a population of cells.

According to the National Center for Education Statistics, White, Latino/a, and Black youth enter into STEM programs at their universities in virtually identical numbers. Unfortunately following the early years of admittance, this is where the previous trend takes a dramatic decline as Black and Hispanic students are more likely to switch out of this field at rates of 40% and 37%, respectively (Riegle-Crumb et al., 2019). These disparities within Black and Hispanic communities regarding retention rate in STEM can oftentimes be attributed to factors such as imposter syndrome, lack of educational resources, and a lack of guidance/mentorship during their undergraduate career– the latter being the main focal point of this study. The purpose of this research is to analyze the impact that mentoring programs have on minority high school students that are interested in pursuing a degree in the field of STEM. Pre- and Post-surveys were utilized during the 2020/2021 academic school year in order to accurately gauge the students’ confidence in the following: applying to STEM programs at their universities of interest, excelling once admitted, and the amount of support they have in doing so. Community Partners include two local high schools in the surrounding DFW metroplex where students are paired with TCU Undergraduates currently pursuing a degree in STEM. Ultimately the following research seeks to examine the effectiveness of mentoring programs in the removal of generational barriers that have historically prevented populations of first-generation, minority students from not only succeeding in institutions of higher education, but ultimately receiving a bachelor's degree within fields of science, technology, engineering, and mathematics.

Separated from their families, many older Americans in assisted living facilities struggle with loneliness and social isolation. The COVID-19 pandemic has only exacerbated this issue, for most facilities have restricted outside visitors due to safety concerns. With the help of the Experiential Projects to Impact the Community (EPIC) Grant, which provides up to $1,500 for a Pre-Health student-led project at TCU that promotes a culture of giving and serves a demonstrated need in the Fort Worth community, a monthly meeting, centered on a craft activity, entitled “Crafts and Conversations” was established at Trinity Terrace to foster community between students at TCU and the residents of a local retirement facility. Through monthly Zoom meetings during the height of the pandemic to masked in-person gatherings at Trinity Terrace, TCU undergraduate students and residents at Trinity Terrace could talk amongst each other while constructing a craft whether that be painting Halloween pumpkins or crafting a winter holiday snow globe. By volunteering in leading these crafts, TCU students have had the chance to build meaningful relationships, improve upon their communication skills in a group dynamic, and been able to address preconceived stereotypes about the elderly. Prior to each craft, each meeting opens with a musical performance that has allowed TCU undergraduate musicians to cultivate and share their craft as well. This project has helped give residents at Trinity Terrace an outlet for social connections through crafts and conversations. Through a commitment to sustainability, “Crafts and Conversations” with Trinity Terrace will endure as a lasting legacy through a crew of committed volunteers who have grown as student leaders by strengthening the Fort Worth community and enriching the lives of the residents at Trinity Terrace.

Professors and Texas Christian University Chemistry students collaborated with O.D. Wyatt High School faculty and students for the rewrite of laboratory experiments. This was done through the lens of green chemistry to best meet the needs of the school’s curriculum scope and sequence with a minimal budget. The primary focus was safety. Safer disposal of hazardous waste, the use of less hazardous chemicals, and a cleanup to provide a safe workspace. Following the redesign of the experiments with the implementation of green chemistry concepts, a thorough cleaning and reorganization of the high school’s storeroom took place. Excess chemicals were safely disposed of, an inventory system was adopted to track presence and location of the remaining chemicals, and all waste and recycling was properly discarded. At the end of this outreach program, O.D. Wyatt gained a revamped curriculum utilizing less hazardous materials, a green chemistry outlook, and a redesigned and safe storeroom. We TCU students gained practical experience redesigning laboratory protocols and adapting them to a green chemistry standard. Additionally, physically applying the techniques learned in the curriculum being taught is invaluable knowledge gained by many students involved. Furthermore, we have also gained the interpersonal communication skills required to simplify complicated concepts to an audience of high school students without scientific backgrounds. This outreach will have long-term positive effects on the high school. The students will be exposed to green chemistry principles and the faculty will see the ease with which green chemistry principles can be added and relished within their curriculum. This program will continue to impact O.D. Wyatt with long-term safety and cost efficiency tactics being employed.

Extinction Learning Deficits Precede Acquisition Deficits in a Mouse Model of Alzheimer’s Disease

Type: Undergraduate
Author(s): Christian Franklin Biology Julia Peterman Psychology Jordon White Psychology
Advisor(s): Michael Chumley Biology Gary Boehm Psychology Meredith Curtis Biology

Alzheimer’s disease (AD) is a progressive brain disorder and the most common form of dementia. The disease gradually destroys brain cells, leading to confusion, erratic behavior, and severe loss of memory. Alzheimer’s is eventually fatal, and no treatment or cure has been discovered. Researchers aim to better understand Alzheimer’s pathology through the use of a transgenic mouse model of AD, the 5xFAD mice. A previous study by Bonardi et al. (2011) has shown that another model of AD, the APP/PS1 mouse, exhibits a deficit in extinction learning before it displays a deficit in acquisition. We aim to determine if this same trend exists in 5xFAD mice, despite having more extensive genetic mutations. Learning will be assessed using the Contextual Fear Conditioning (CFC) paradigm, where the mice are introduced to an environmental context and experience a mild aversive stimulus. When reintroduced to the context 24 hours later, mice will freeze if they acquired a memory for the pairing of an aversive stimulus with the novel context. Freezing is an instinctive rodent fear response. After repeated trials of exposure to the environment in the absence of an aversive stimulus, the mice gradually freeze less. This is indicative of new learning of the environment no longer being paired with the stimulus, or extinction of the initial association. The 5xFAD mice typically exhibit impaired acquisition by 6 months of age as compared to wild type mice. The present study examined if the 5xFAD mice would display a deficit in extinction learning prior to this deficit in acquisition. Preliminary data indicate that 5xFAD mice, like APP/PS1 mice, show a deficit in memory extinction before they exhibit a loss of memory acquisition. Three-month old FAD mice extinguish more slowly than three-month old wild type mice, but show no difference in acquisition. This research is important because it indicates alternative cognitive measures may allow for earlier diagnosis of neurodegenerative diseases, such as AD.

Reducing ROS and Chelating Metal Ions in Neuronal Cells Using Novel Compounds

Type: Undergraduate
Author(s): Olivia Kinsinger Interdisciplinary
Advisor(s): Giridhar Akkaraju Biology

It is estimated that 45% of people over the age of 85 in the U.S. suffer from Alzheimer’s disease. Patients with Alzheimer’s disease, which is characterized by cognitive deficiencies and memory loss, have higher concentrations of amyloid plaques in brain tissue than patients without the disease. Abnormal levels of transition metal ions Fe, Zn, and Cu in brain tissue are associated with amyloid beta plaques and also have been shown to catalyze the generation of excess reactive oxygen species (ROS) and cause oxidative stress. The combination of the ROS generation and the amyloid plaque formation results in neurodegeneration, which ultimately causes the memory loss and ultimate death associated with Alzheimer’s. We have synthesized the compounds L2 and L4 which are designed to be chelating agents of metal ions and also scavengers of ROS. We hypothesize that due to their chelating properties and pyridol groups, L2 and L4 should reduce oxidative damage in neuronal cells by chelating metal ions and scavenging radicals. Furthermore, we hypothesize that due to its extra pyridol group, L4 will be a stronger antioxidant than L2. The cytotoxicity of the compounds was tested on HT-22 neuronal cells. Neuronal cells will be treated with BSO, a compound that induces formation of ROS, in the presence and absence of L2 and L4. If our hypothesis is correct, our compounds should reduce the oxidative damage induced by BSO, and L4 should be more effective at doing so than L2.

Advisor(s): Gary Boehm Psychology Michael Chumley Biology Meredith Curtis Biology

Alzheimer’s disease (AD) is a neurodegenerative condition in which beta-amyloid protein accumulates into plaques, and tau protein forms neurofibrillary tangles. In the past, our laboratory has shown that repeated inflammatory events increase beta-amyloid in the hippocampus of male C57BL6/J mice. We sought to determine the effect of a second exposure to the bacterial mimetic lipopolysaccharide (LPS) on beta amyloid accumulation. An initial round of seven, once daily LPS or sterile saline injections, was administered to male C57BL6/J adult mice. Fourteen days after the last injection, a second round of LPS or saline injections was given, followed by tissue collection and quantification of beta-amyloid levels in the hippocampus. The results showed that animals injected with two rounds of LPS had significantly lower levels of beta-amyloid accumulation than those animals injected with just a single round of LPS, although both groups had significantly higher levels of beta-amyloid than the saline control animals. These results suggest a reduced inflammatory response following a secondary exposure to LPS. More specifically, animals exposed to LPS for a second time showed significantly less central and peripheral inflammation four hours after LPS administration than animals with no prior exposure. In addition, increased levels of IgM and IgG were discovered in the mice with prior LPS exposure. This could indicate possible antibody production against LPS or beta-amyloid rather than tolerance of the LPS as a mechanism for the reduced inflammatory response. In order to establish whether this results in a life-long effect, we are currently exploring the impact of LPS administration in old age for mice who were exposed to LPS earlier in life.
