Assessing Bacterial Adhesion To Metallic Coating On Silicone For Peritoneal Dialysis Catheters, Lexi Phillips, Trent Peterson, Mark Mortensen
Student Research Symposium
The aim of this project is to design a test to demonstrate the effectiveness of a coating applied to the lumen of peritoneal catheter extensions to reduce biofilm formation. Hemodialysis and peritoneal dialysis (PD) patients currently struggle with infections caused by biofilm growth in the intraluminal tubing. Once established, biofilms are very difficult to get rid of and can cause reoccurring infection issues which can lead to a discontinuation of PD, poorer quality of life, and a greater risk of death. Fresenius Medical Care (FMC) has recognized similar problems with their patients and seeks to reduce infection rates. Fresenius Medical …
Bioprinting Of Hagfish Keratin Proteins, Nathan Harward
Bioprinting Of Hagfish Keratin Proteins, Nathan Harward
Student Research Symposium
Proteins make up most tissue scaffolding within the human body, making novel proteinaceous biomaterials highly sought-after since they can be designed to mimic the natural ECM of various tissues. Hagfish secrete a proteinaceous slime when threatened that clogs the gills of predators, and the keratin proteins found in the slime show promise as a potential tissue scaffold material. In this study, recombinant hagfish proteins were used to formulate a bioink which was crosslinked into hydrogels. Characterization of the hydrogel porosity and mechanical properties revealed a tunable nature valuable for artificial tissue scaffold engineering. The availability of in-house genetic modification of …

Modeling Of The Engineered Production Of Curcumin In Escherichia Coli, Ellie Siddoway
Modeling Of The Engineered Production Of Curcumin In Escherichia Coli, Ellie Siddoway
Student Research Symposium
Curcumin is the major bioactive natural product in turmeric (Curcuma longa), which is commonly used as a food additive (flavor and colorant) and traditional medicine for thousands of years. This polyphenol has a variety of biological activities, such as antioxidant, anti-cancer, anti-allergic, anti-inflammatory, and anti-Alzheimer’s effects. The current production process of this promising natural product is not environmentally friendly or cost-effective. However, microbial production represents a great alternative because of the significantly reduced production time and reproducible production process. Our group has previously introduced the required enzymes into Escherichia coli to construct an artificial curcumin production pathway in the bacterium. …

The Good From The Ugly: Fermentation Optimization For Hagfish Protein Production, Simon Hulme, Zach Hyde, Ben Florschutz, Caeman Nicholas
Student Research Symposium
When under attack the noble hagfish produces a protective slime that rapidly expands in water to clog the gills of their attacker. The protein threads that hold the slime together caught the eye of Dr. Jones’ Lab here at USU.These proteins, alpha and gamma, have properties very similar to spider silk making them a material of interest to the US Navy. While the Jones lab has already genetically engineered a strain of E. coli to produce these filament proteins the process has not been optimized. This group plans to increase protein production by 20% (from 8 g/L to 9.6 g/L) …

Mechanical Methods For Bioreactor Foam Breaking, Ceaira Howard, Bodee Hancock, Adam Martin, Laurent Saysanavong
Student Research Symposium
ThermoFisher Scientific, through the lead of Jason Brown, has commissioned a design team at Utah State University (USU) to create a mechanical foam breaker capable of being used in a single use bioreactor setup. The goal of this design team was to find mechanical methods of foam breaking for reactors of 30 L volume and 300 L volume to reduce the need for chemical antifoam agents which, in concentrations higher than 1% total volume, can lead to higher optical densities and lower protein yield (Routledge, 2012). Initial designs include a rotating mechanical cone (derived from ThermoFisher), a wire bristle apparatus, …

Plant Identification In A Combined-Imbalanced Leaf Dataset, Viraj K. Gajjar, Anand K. Nambisan, Kurt Louis Kosbar
Electrical and Computer Engineering Faculty Research & Creative Works
Plant identification has applications in ethnopharmacology and agriculture. Since leaves are one of a distinguishable feature of a plant, they are routinely used for identification. Recent developments in deep learning have made it possible to accurately identify the majority of samples in five publicly available leaf datasets. However, each dataset captures the images in a highly controlled environment. This paper evaluates the performance of EfficientNet and several other convolutional neural network (CNN) architectures when applied to a combination of the LeafSnap, Middle European Woody Plants 2014, Flavia, Swedish, and Folio datasets. To normalize the impact of imbalance resulting from combining …
Sex With Robots And Human-Machine Sexualities: Encounters Between Human-Machine Communication And Sexuality Studies, Marco Dehnert
Sex With Robots And Human-Machine Sexualities: Encounters Between Human-Machine Communication And Sexuality Studies, Marco Dehnert
Human-Machine Communication
Sex robots are a controversial topic. Understood as artificial-intelligence enhanced humanoid robots designed for use in partnered and solo sex, sex robots offer ample opportunities for theorizing from a Human-Machine Communication (HMC) perspective. This comparative literature review conjoins the seemingly disconnected literatures of HMC and sexuality studies (SeS) to explore questions surrounding intimacy, love, desire, sex, and sexuality among humans and machines. In particular, I argue for understanding human-machine sexualities as communicative sexuotechnical-assemblages, extending previous efforts in both HMC and SeS for more-than-human, ecological, and more fluid approaches to humans and machines, as well as to sex and sexuality. This …

Considering The Context To Build Theory In Hci, Hri, And Hmc: Explicating Differences In Processes Of Communication And Socialization With Social Technologies, Andrew Gambino, Bingjie Liu
Human-Machine Communication
The proliferation and integration of social technologies has occurred quickly, and the specific technologies with which we engage are ever-changing. The dynamic nature of the development and use of social technologies is often acknowledged by researchers as a limitation. In this manuscript, however, we present a discussion on the implications of our modern technological context by focusing on processes of socialization and communication that are fundamentally different from their interpersonal corollary. These are presented and discussed with the goal of providing theoretical building blocks toward a more robust understanding of phenomena of human-computer interaction, human-robot interaction, human-machine communication, and interpersonal …

Autism has been characterized by a tendency to attend to the local visual details over surveying an image to understand the gist–a phenomenon called local interference. This sensory processing trait has been found to negatively impact social communication. Although much work has been conducted to understand these traits, little to no work has been conducted to intervene to provide support for local interference. Additionally, recent understanding of autism now introduces the core role of sensory processing and its impact on social communication. However, no interventions to the end of our knowledge have been explored to leverage this relationship. This work …

Structural Health Monitoring Of Bioprinted Materials, Kathryn H. Mcintosh
Honors College Theses
Bioprinting is a new method that utilizes additive manufacturing to construct organs, tissues, and other biostructures. This method presents endless possibilities - less reliance on organ donors (according to the Health Resources and Services Administration, 17 people die each day waiting for an organ transplant in the U.S.), more transplant opportunities, and the ability to save significantly more lives. While bioprinting has opened a new frontier in the biomedical field, there may be some research issues that need to be addressed. For example, numerous researchers have focused on creating novel approaches to print complicated geometries. However, the structural integrity or …
Model-Guided Design Of Rna-Based Synthetic Circuits For The Dynamic Regulation Of Gene Expression, Jordan R. Ryan
Model-Guided Design Of Rna-Based Synthetic Circuits For The Dynamic Regulation Of Gene Expression, Jordan R. Ryan
LSU Master's Theses
A longstanding goal in synthetic biology has been to build synthetic gene circuits with the ability to harness nature’s capability of precise gene expression regulation. Advancements in RNA technology have established RNA-based regulators with distinct advantages over traditional protein-based regulators such as faster signal propagation, versatile programmability, and low cellular burden, which has created an interest in the field to construct innovative synthetic gene circuits using de novo RNA- based regulators. However, our understanding of the behavior and kinetics of RNA-RNA interactions for the construction of gene circuits is incomplete. This thesis proposes a model-guided design framework that integrates mechanistic …

The Melanocortin-1 Receptor gene (MC1R) encodes a protein that is associated with pigmentation in vertebrate animals. An extraordinary number of variations in this gene have arisen over time due to the importance of pigmentation in camouflage, photosensitivity, vitamin D production, and other evolutionary factors. Variations in the MC1R gene sequence became important to survival as humans migrated out of Africa and into cooler climates with less sun exposure, where lighter skin pigmentation (and therefore more vitamin D production) was key to survival. These genetic variations (alleles) continue to exist in modern humans. Recent research into the MC1R gene variations shows …

Yeast are eukaryotic organisms that contain liner chromosomes. At the ends of these chromosomes, there are special regions known as telomeres. Telomeres are composed of non-coding nucleotides that serve to protect the vital coding DNA found throughout the rest of the chromosome. During the process of DNA replication, however, telomeres become progressively shorter which can lead to cellular senescence. To solve this issue, yeast express the enzyme telomerase. Telomerase is composed of a telomerase reverse transcriptase protein (TERT) and telomerase RNA (TLC1) in yeast. When telomeres become too short, telomerase extends telomeres by adding to the 3’ overhang. Telomeres shorten …

A knowledge gap associated with how fungal communities change in response to climate was identified in the 2018 State of the World Fungi report (Willis, 2018). While it is virtually impossible to test in the present, fungal assemblage changes can be studied in sediments from a warmer-than-present period such as the Miocene Climate Optimum (MCO) (Romero et al. 2021; O’Keefe 2017). The Fungi in a Warmer World project aims to generate and analyze a global-scale data set of fungal biodiversity, ecology, and associated flora from MCO sediments. This dataset will be used to model past fungal assemblage changes across the …

Morphometrics Of The Rare Earwigfly Merope Tuber, Nicholas Finch, Sean O'Keefe
2022 Celebration of Student Scholarship - Poster Presentations
Merope tuber Newman (Mecoptera: Meropeidae) is a rare North American species of earwigfly, which is closely related to common scorpionflies. “Earwigfly” refers to three different species: the Western Australian Austromerope poulton, the South American Austromerope brasiliensis, and finally, the Eastern North American Merope tuber. This last species was the focus of our study. Johnson’s 1995 study was based on 160 earwigflies, where he measured the female abdomen length, male and female forewing length, and male basistylus and dististylus length. In their 2014 study, based on 82 earwigflies, Skvarla, Hartshorn, and Dowling measured head width, pronotum width, forewing length, abdomen length, …

Chromosomes are molecules of DNA that hold large quantities of genetic material in an organism. Generally, in nature, eukaryotic chromosomes are linear while prokaryotic chromosomes are circular. Since they are linear, eukaryotic chromosomes possess telomeres, or repetitive nucleotide sequences, on their ends. This significant difference in structure requires different additions to the basic replication process. In prokaryotes, replication starts at a single point on the chromosome and continues until the whole chromosome has been copied. In eukaryotes, replication happens in fragments with multiple starting points. Because of this more complicated replication process, the free 3’ ends of our DNA cannot …

A New Colorimetric Assay Of Apurinic/Apyrimidinic (Abasic) Sites Of Deoxyribonucleic Acid (Dna) Using Bicinchoninic Acid [, Isaiah O. Stephens, Elizabeth M. Thomas
2022 Celebration of Student Scholarship - Poster Presentations
Apurinic/apyrimidinic (AP or abasic) sites are DNA lesions that result from the loss of a nucleobase by hydrolysis of the N-glycosyl bond. It is estimated that AP sites are the most frequent lesions in cells with about 10,000-50,000 times per day per cell under typical aerobic conditions [2]. The formation of AP sites is caused by environmental and cancer therapeutic genotoxins such as alkylating agents, oxidizing agents, ionizing radiation, and ultraviolet radiation.

Having a multitude of definitions, biodiversity can most commonly be seen as the variety and diversity of life within an ecosystem. Its relevance is crucial for species survival and resource availability; a lack of biodiversity sets an ecosystem up for failure, reducing its productivity, species richness, and increasing organismal vulnerability. Measuring biodiversity is crucial for the understanding of an ecosystem’s health, giving scientists knowledge of its stability, productivity, and persistence. This collected information can be implemented in various ways outside the scientific field as well, such as with policy decisions and legal regulations. Biodiversity is most commonly analyzed through quantitative …

2022 Celebration of Student Scholarship - Poster Presentations
Quantitative sampling of organisms is often used to provide information in ecological studies, monitor populations, and aid in biodiversity projects. Many studies involve the quantitative sampling of spiders. In this meta-analysis study, 207 peer-reviewed journal articles formed the basis of an initial data set for a quantitative analysis of spider collection techniques. Data collected included country of study, mode of study, trapping techniques used, spider diversity, and number of specimens collected. Our meta-analysis gathered research articles that included 33 different countries of study. Trapping techniques greatly vary depending on the habitat in which spiders dwell. These were divided into aerial, …

Biodiversity is the measure of variability of interactions between living organisms within an area. Biodiversity contributes significantly to the production of different life sustaining resources and supports a diversity of ecological life. A greater biodiverse area can help maintain environmental balance and maintain ecological diversity and health. There are multiple economic, cultural, and scientific reasons as to why biodiversity is important. When assessing biodiversity, mammals and birds are commonly used as surrogates. The problem with mammals and birds is that there are relatively few species and relatively few individuals in an area, so quantitative assessment can be difficult. However, insects …

Survey Of Spiders Within Eastern Kentucky, Mercy Hailu, Bailey Bullock, Joshua Hicks, Eliana Eldridge, Sean O'Keefe
2022 Celebration of Student Scholarship - Poster Presentations
Biodiversity is known to be the variation of living organisms compromising several levels, beginning from genes, then species, communities, then finally ecosystems. Biodiversity is crucial in maintaining ecological balance, boosting ecosystem productivity, and determining the quality of ecosystem services such as pest management in agriculture. Being aware of biodiversity's importance can also help with the prevention of continuous threats to biodiversity and be best prepared to manage conservation challenges. Typically, mammals, birds, and plants are used to assess biodiversity. However, spiders may be effective in indicating environmental change because they are taxonomically quite diverse, species fill a variety of ecological …

Creating The First Genetically Engineered Eukaryote With Circular Chromosomes, Duncan Mcginnis, Melissa Mefford
2022 Celebration of Student Scholarship - Poster Presentations
Prokaryotes and eukaryotes differ in their chromosome structure; prokaryotes have a single circular chromosome, while eukaryotes have multiple circular chromosomes. Linear chromosomes are more complex than circular ones and create problems for eukaryotes. Many of these issues are solved by telomeres—long, repetitive sequences of DNA found on the ends of most eukaryotic chromosomes. They protect the ends from harm and limit how many times a cell can divide. Two of our greatest medical challenges, cancer and aging, are closely related to telomeres; most cancers upregulate telomerase, and aging human cells display shorter telomeres. To investigate the evolution and function of …

Fungi play a key role in the terrestrial carbon cycle, soil formation, and overall plant growth as terrestrial decomposers (1, 2). Thus, the study of fungi, especially in the fossil record, is critical to understanding how fungal assemblages will react to future warming events. Fossil fungi provide a large-scale, long-term dataset unavailable from modern records, allowing for the generation of viable paleoclimate reconstructions and predictions (3, 4). Despite their importance and advantages in forming ecological and climatological interpretations, deep-time fungi have been underutilized (3). The Fungi in a Warmer World (FiaWW) project aims to deliver the first global view of …
