The Use Of Inertial Measurement Unit For The Characterization Of Multiple Functional Movement Patterns In Individuals With Chronic Ankle Instability, Seunguk Han

Theses and Dissertations

Patients with a history of lateral ankle sprain (LAS) may experience different levels of mechanical and/or sensorimotor deficits following their injuries. Although various factors, such as structural damage, sensorimotor adaptation, perceived instability, swelling and/or pain, can develop and perpetuate the condition of chronic ankle instability (CAI), most previous CAI research on biomechanics has considered all patients with CAI as a homogeneous group. Recent research has clustered patients with CAI into six distinct movement patterns during a maximal jump-landing/cutting task. This approach could motivate clinicians to develop appropriate rehabilitation programs for each patient with CAI depending on their movement patterns. However, …

Quantifying The Toxicological Effects Of The Organic Uv Filters Avobenzone And Homosalate On Acropora Cervicornis, Samantha F. Buckley

All HCAS Student Capstones, Theses, and Dissertations

Reports of the environmental effects of organic UV filters such as oxybenzone have led to the marketing of “reef-safe” sunscreen ingredients, including avobenzone and homosalate. Avobenzone provides broad-spectrum UV protection which blocks higher wavelength UV rays, the leading cause of aging and skin cancer. However, as polycyclic aromatic hydrocarbons (PAHs), organic UV filters have similar structures to crude oil and estrogens, some of which have been labeled endocrine disrupters. Common in personal care products, UV filters enter marine ecosystems via wastewater effluent and swimmers. Significant stress and mortality have been observed in juvenile and some adult scleractinian corals after exposure …

Toxicity And Effectiveness Of A New Two-Part Underwater Adhesive For Coral Restoration, Matthew Rojano

All HCAS Student Capstones, Theses, and Dissertations

As coral cover decreases around the world due to disease, bleaching events, and anthropogenic effects, coral restoration projects become increasingly important. A crucial part of many coral restoration projects is the attachment of corals to substrates in nurseries or reef substrates during outplanting. The effective anchoring of transplants is a critical phase in coral restoration and the adhesive used for attachment is crucial. Commonly used adhesives have several drawbacks: there are long mixing times, low substrate adhesion, and lengthy hardening times. To address these issues and provide an effective alternative for coral restoration activities, a new two-part Mixed Adhesive was …

Faculty, Staff and Student Publications

Penile Squamous Cell Carcinoma (PSCC) is associated with high-risk human papillomavirus (HR-HPV). The immunohistochemical (IHC) test for p16INK4a (p16) is highly correlated with HR-HPV expression in other SCCs. To investigate whether the expression of p16 IHC or HR-HPV is associated with survival in PSCC, we conducted a single institution analysis of 143 patients with a diagnosis of PSCC and, available tissue were tested for p16 IHC staining patterns, histological subtype, tumor grade, and lymphovascular invasion (LVI) by an experienced pathologist. HR-HPV status using the Cobas PCR Assay or the RNAScope high-risk HPV in situ hybridization kit were also assessed. Patient …

The Role Of Long Non-Coding Rna (Lncrna) In The Organization Of Nuclear Bodies, Soobin An

Symposium of Student Scholars

Nuclear bodies (NBs) (e.g., the nucleolus, nuclear speckles, and others) are membraneless compartments within the eukaryotic cell nucleus that selectively accumulate and retain specific nuclear proteins. NBs have become a new interest in recent discoveries because of their potential involvement in cancer and neurological disorders. However, the regulation and function of NBs are still enigmatic. Our laboratory studies a specific type of NBs, called B-bodies, to understand how NBs are formed and regulated in the nucleus. We hypothesized that long non-coding RNA (lncRNA) functions as a structural scaffold of NBs.

The B-body is a recently discovered NB expressed in the …

Guano Among Bat Species From Two Regions Shows Influence Of Geography And Diet On Bacterial Community, Rahma Ahmed, Thomas Mcelroy, Shannon Whitney, Lydia Moore

Symposium of Student Scholars

Studies of bat guano have shown that the diversity and structure of associated microbial communities can be related to factors such as host phylogeny, life history and reproductive stage, geography, and diet. Many insectivorous bat species in the southeastern U.S. have generalist diets that may shift seasonally to take advantage of abundant prey species or maximize caloric intake. Seasonal shifts in prey availability or consumption should be reflected in a guano microbiome change. We also expected to detect distinct guano microbiomes within species. Within species, distinct microbial communities related to geography, and finally life history and reproductive stage. We compared …

Reducing Skin Injury And Breakdown In Neonatal Patients, Emily Herring

Symposium of Student Scholars

Abstract

The integumentary system is known for being the body’s largest organ, comprised of water, fats, protein, and minerals, for which composition plays a significant role in protecting the body against thermal, chemical, and microbial agents. However, the skin’s functionality is reduced in neonates as the stratum corneum is thin at birth due to diminished water-holding capacity (Oranges et al., 2015). The skin’s fragility is further stressed among preterm neonates and newborns in neonatal intensive-care units (NICU) due to medical status, procedures, and exposure to skin irritants (Visscher et al., 2009). Reduction in skin injury and breakdown in NICU patients …

Alternative Precautionary Measures Yielding Lower C. Diff Infection Rates In Healthcare Facilities, Matthew Kramer

Symposium of Student Scholars

Background: An international healthcare concern is the persistent spread of Clostridium difficile, a Gram-positive spore forming bacterium that is responsible for the most common hospital-acquired infection, amongst patients.

Objective: A systematic review was performed to summarize evidence that the interventions utilized in healthcare facilities which indicate a patient’s precautionary status are insufficient, outdated, and commonly lead to infection in neighboring patient rooms. Databases such as PubMed, NCBI, Google Scholar, and APHA’s Medical Care were searched, covering the period from 2017-2022. Studies were included if their focus concentrated on C. diff and the precautionary measures taken by employees at healthcare …

Insect Availability And Parental Care Behavior In A Common Bird, Cole Bourque

Symposium of Student Scholars

Populations of aerially insectivorous birds are declining throughout North America. Urbanization may indirectly contribute to this decline through its negative effects on populations of insects, an important food source in insectivores' diets, where low insect availability may be especially challenging for birds during breeding. How fluctuations in insect populations impact various species at higher trophic levels is an important area of current study for future conservation biology. Here, we examine whether nestling provisioning, brooding and guarding behaviors in a breeding bird—the European starling (Sturnus vulgaris)—may be altered depending on the relative insect availability in the environment. We found …

Detecting Bacterial Species From Ancient Human Skeletal Samples, Ariel Owens, Daisy Mcgrath, Tsai-Tien Tseng

Symposium of Student Scholars

Diagnosis of tuberculosis (TB) via morphological analysis is difficult and often inconsistent. With next-generation sequencing (NGS), ancient host microbiomes can be subjected to metagenomic analyses for the detection of TB in silico. Suitable bioinformatic workflows are needed for reliable ancient DNA (aDNA) analysis of causative agents. This study aims to enhance available bioinformatic screening methods to create more suitable bioinformatic processes and generate insights in relation to TB.

This research utilizes publicly available NGS data accessed through the Sequence Read Archive (SRA) of the National Center for Biotechnology Information (NCBI). Initial quality control steps included adapter trimming with Trim …

Designing And Synthesizing A Warhead-Fragment Inhibitory Ligand For Ivyp1 Through Fragment-Based Drug Discovery, Samuel Moore

Symposium of Student Scholars

Fragment-based drug discovery (FBDD) is a powerful tool for developing anticancer and antimicrobial agents. Within this, magnetic resonance spectroscopy (NMR) provides a comprehensive qualitative and quantitative approach to screening and validating weak and robust binders with targeted proteins, making NMR among the most attractive strategies in FBDD. Inhibitor of vertebrate lysozyme (Ivyp1) of P. aeruginosa serves as an excellent target because of its active cellular location and implications in clinical prognosis for cystic fibrosis and immunocompromised patients. This study uses current NMR and biophysical techniques to develop a covalent, fragment-linked warhead inhibitor for Ivyp1 through synthetic methods, warhead linking, and …

Characterization Of Caenorhabditis Elegans F07a5.4, Human Ortholog Of Olfactomedin 1, Sade K. Thomas, Karunambigai Kalichamy, Martin Hudson

Symposium of Student Scholars

Accurate control of nervous system development is critical for normal brain patterning, and defects in this process can lead to neurological disorders such as schizophrenia and Autism Spectrum Disorder. The transcription factor neurogenin is necessary for the development of neural subtypes and is deeply conserved across species. However, the transcriptional targets of neurogenin are poorly understood, creating an imperative for further study. We have used the nematode Caenorhabditis elegans as a model to better understand ngn-1/neurogenin function. Previous work from our lab revealed that ngn-1 plays a role in nerve ring architecture, and neural cell fate specification. In addition, …

Preliminary Analysis Of The Effects Of Non-Target Supplemental Feeding On Camera Trap Captures Of Small Mammals In Central Georgia, Raena Mccown, Travis Cunningham, Alfred J. Mead

Georgia Journal of Science

Supplemental bird feeding is a widespread hobby throughout western culture. Although it brings joy to many people, bird feeding has been shown to have potentially negative effects on local bird populations and small mammalian species. To study the differences in local occurrence of native small mammalian species around bird feeders and in more distant settings, six camera traps were placed in a rural residential area in Putnam County, Georgia. Three cameras were placed facing bird feeders and three placed a minimum of 60 m away from the feeders. Species presence was recorded three days a week from 12:00 am Monday …

Fall Student Research Symposium 2022

My presentation is on the Isolation of Bacterial and Fungal Microbes from the Rhizosphere of Shepherdia x utahensis 'Torrey' also known as Hybrid Buffaloberry. Hybrid Buffaloberry is a combination between two varieties native to the Intermountain West: Shepherdia argentea, a highly drought tolerant variety, and Shepherdia rotundifolia, a common more aesthetically pleasing variety. Both native varieties are well documented to have nodule forming microbes that help aid their development in such harsh conditions. We acquired our Rhizosphere sample by shaking the roots and nodules from our sample in a phosphate buffer and serially diluted it to a useful concentration. We …

Facilitative Parasitization Of Brown Marmorated Stink Bug Eggs Between Native And Invasive Trissolcus Wasps, Zachary Ross

Fall Student Research Symposium 2022

The Brown Marmorated Stink Bug (Halyomorpha halys, BMSB) is an extremely successful invasive species with over 300 different host plants ranging from ornamental to agricultural species. One of the primary controls of BMSB in their native range is the parasitoid wasp Trissolcus japonicus (T.j). While T.j has the ability to control BMSB populations, native species of parasitoid wasp have also been documented targeting BMSB eggs, although with minimal success. The primary objective of this study was to determine whether or not a beneficial facilitative relationship existed between the invasive Trissolcus japonicus and the native egg parasitoid Trissolcus euschisti (T. eu). …

Instructional reform in STEM aims for the widespread adoption of evidence based instructional practices (EBIPS), practices that implement active learning. Research recognizes that faculty social networks regarding discussion or advice about teaching may matter to such efforts. But teaching is not the only priority for university faculty – meeting research expectations is at least as important and, often, more consequential for tenure and promotion decisions. We see value in understanding how research networks, based on discussion and advice about research matters, relate to teaching networks to see if and how such networks could advance instructional reform efforts. Our research examines …

Chemical Control And Understanding Of Horizontal Gene Transfers, Drug-Resistance Development, And Filament And Biofilm Formation, Yuchen Jin

Dissertations - ALL

Biofilms formed by microbes on surfaces are the sources for persistent infectious diseases and environmental problems. The mechanism and details of how antibiotics promote biofilm formation is largely unknown. For instance, it not clear what stages of biofilm growth are promoted to proceed faster than without antibiotics, what phenotypes of bacteria form in an antibiotic-promoted biofilm, and what different biofilm compositions and structures are caused by the presence of antibiotics. Among other effects, antibiotics can cause bacteria to form filaments of living bacteria. Here, we conduct a real-time study of the adherence of bacteria and antibiotic-induced filamentous bacteria on surfaces …
