“The Never Ending Story:” Circularizing Ch. Viii In Saccharomyces Cerevisiae, Chisom Iloegbunam, Melissa Mefford

2022 Celebration of Student Scholarship - Poster Presentations

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.

A Preliminary Survey On The Biodiversity Of Wasps In Eastern Kentucky, Lorien Molstad, Zoe Baker, Julia Fitzpatrick, Bethany Lucio, Sean O'Keefe

2022 Celebration of Student Scholarship - Poster Presentations

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 …

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 …

2022 Celebration of Student Scholarship - Poster Presentations

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 …

Lyapunov-Based Economic Model Predictive Control For Detecting And Handling Actuator And Simultaneous Sensor/Actuator Cyberattacks On Process Control Systems, Henrique Oyama, Dominic Messina, Keshav Kasturi Rangan, Helen Durand

Chemical Engineering and Materials Science Faculty Research Publications

The controllers for a cyber-physical system may be impacted by sensor measurement cyberattacks, actuator signal cyberattacks, or both types of attacks. Prior work in our group has developed a theory for handling cyberattacks on process sensors. However, sensor and actuator cyberattacks have a different character from one another. Specifically, sensor measurement attacks prevent proper inputs from being applied to the process by manipulating the measurements that the controller receives, so that the control law plays a role in the impact of a given sensor measurement cyberattack on a process. In contrast, actuator signal attacks prevent proper inputs from being applied …

In this paper, we review the research literature to identify models and ideas that could lead to fully unsupervised ASR, including unsupervised sub-word and word modeling, unsupervised segmentation of the speech signal, and unsupervised mapping from speech segments to text. The objective of the study is to identify the limitations of what can be learned from speech data alone and to understand the minimum …

Clostridioides Difficile Spore Production In Response To Antibiotic And Immune Stress, Adenrele Oludiran, Erin B. Purcell

College of Sciences Posters

Clostridioides (Clostridium) difficile, an anaerobic, spore-forming Gram-positive pathogenic bacterium, is a major cause of hospital-acquired infections and can persist as surface-attached biofilms for protection from antibiotic and immune stress. C. difficile can form biofilms as a single species or with other anaerobic intestinal bacteria. The environmental signals that cause individual cells to secrete toxins, form biofilms, or develop into spores that can spread the infection to new patients are unknown. In these studies, we investigate bacterial responses to different stress. Antimicrobial host-defense peptides (HDPs) produced by animal immune systems are promising candidates to develop novel therapies for bacterial infection …
