Altered Gametogenesis Gene Expression Of The Eastern Oyster (Crassostrea Virginica) In Response To Plastic Exposure, Marissa Kordal Apr 2021

Altered Gametogenesis Gene Expression Of The Eastern Oyster (Crassostrea Virginica) In Response To Plastic Exposure, Marissa Kordal

Transformations: Presentation Slides

Marine plastic pollution leaches chemicals that cause detrimental effects such as reduced fecundity and feminization of males in marine species. The eastern oyster, Crassostrea virginica, is a valuable species to study the effects of plastic on sex differentiation because it is a protandric hermaphrodite that undergoes gametogenesis yearly. My objective was to investigate a potential cause of an observed female-skew in the sex ratio of first year oysters exposed to plastic by measuring differential gene expression of eight gametogenesis genes from oysters grown on plastic compared to those on shell. Plastic exposure increased the expression of genes involved in egg ...

Exotic Legume's Leaf Litter Beneficial To Prairie Plants, Asher Gardner Apr 2021

Exotic Legume's Leaf Litter Beneficial To Prairie Plants, Asher Gardner

Biology

Lespedeza cuneata is an invasive, non-native species of bush clover that is invading prairies where the native Lespedeza capitata grows. Both species of bush clover are legumes, which are nitrogen fixers. Legumes and their senescent leaves (i.e., “litter”) are well known for increasing levels of available nitrogen in the soil. However, the exotic L. cuneata also produces tannins that reduce the rate of germination in some prairie plants. The purpose of this study was to clarify whether these compounds in the litter of the invasive species of bush clover deter early growth in its native competitors, and to determine ...


Creepy Crawly Compensation: Examining The Costs Of Ectoparasite-Induced Compensatory Growth In Late-Stage Nestlings, Elliot Lusk Apr 2021

Creepy Crawly Compensation: Examining The Costs Of Ectoparasite-Induced Compensatory Growth In Late-Stage Nestlings, Elliot Lusk

Biology

When normal growth rates are suppressed, organisms may undergo a rapid period of increased growth in order to match the physical requirements of a developmental benchmark. This compensatory growth, however, is not without its costs, which can have varying consequences. In nestlings, a major benchmark is that of fledging, which requires advanced physical maturation. In previous studies, compensatory growth and some of its associated costs have been shown in prefledging nestlings but fledging-aged nestlings and the costs they may have sustained needs further study. Here we examine the costs of compensatory growth in late-stage European starling (Sturnus vulgaris) nestlings under ...

Catalogue Of Lichen Species In The Rowan County Sphagnum Swamp, Rowan County, Kentucky, Deanna Kidd, Allen Risk

2021 Celebration of Student Scholarship - Poster Presentations

Rowan County Sphagnum Swamp is one of the best remaining examples of a bottomland swamp forest left in the Knobs region of Kentucky. Bottomland swamp forests are characterized by soil with a high percentage of organic matter above clay and Devonian shale. This arrangement leads to standing water much of the year and a strongly acidic soil. Common tree species in the Rowan County Sphagnum Swamp include Acer rubrum (red maple), Quercus palustris (pin oak), Liquidambar styraciflua (sweet gum), Nyssa sylvatica (sour gum) and Betula nigra (river birch). Bottomland swamp forests used to be more common, but have dwindled due ...


Analytical Method Development For The Analysis Of Biomass Degradation Products, Calista Dean, Emma Schmittzehe Apr 2021

Analytical Method Development For The Analysis Of Biomass Degradation Products, Calista Dean, Emma Schmittzehe

2021 Celebration of Student Scholarship - Poster Presentations

The goal of this project is to study the kinetics of hydrothermal liquefaction of biomass. Biomass contains stored chemical energy that can be converted to renewable liquid and gaseous fuels through various processes, but an in-depth understanding of the kinetics of these processes is important in order for them to be feasible on a large scale. Since biomass degradation products depend on the type of biomass used as well as the reaction conditions, this task can be quite complicated. To minimize complications in our initial studies, we will use D-glucose as the starting material. To better understand the degradation pathway ...

2021 Celebration of Student Scholarship - Poster Presentations

Student teaching is the capstone of student teaching preparation. The Covid-19 pandemic has changed many aspects of student teaching; and students have had to adapt to a new way of both learning and teaching. As the world turned upside down, student teachers were expected to interact with their students and provide instruction. The pandemic caused student teachers to develop new ways to engage lessons and hold conversations in a virtual environment. This pilot study examines the ways in which a small group of student teachers in eastern Kentucky internalized their experience.

A Protocol To Overcome The Negative Health Effects Associated With Urinary Catheters In The Hospital Setting; A Quality Improvement Project, Katelynn Arnett, Mary Bott, Abigail Bray, Dakota Brown, Zachary Mains, Suzi White

2021 Celebration of Student Scholarship - Poster Presentations

There are estimated to be 449,334 CAUTI events per year (hospitalsafelygrade). As well, this costs the health care system to the United States Healthcare System which shows that it costs the country an extra 340-370 million every year (Gray et al., 2016). The purpose of this quality improvement project is to determine how to overcome the negative effects that patients experience when receiving catheters (indwelling or external) while in the hospital. Increased catheter rates and infections were noted at an urban teaching hospital which led to the creation of this new protocol guideline.

Genetically Screening For Gain Of Function Mutations In Telomerase Rna, Jose Childers, Melissa Mefford Apr 2021

Genetically Screening For Gain Of Function Mutations In Telomerase Rna, Jose Childers, Melissa Mefford

2021 Celebration of Student Scholarship - Poster Presentations

Telomeres are DNA structures located at the ends of linear chromosomes. They function, in part, to allow DNA ends to be copied before cells divide. Since the standard DNA replication machinery can’t fully copy telomeres, most eukaryotic cells require the vital ribonucleoprotein enzyme telomerase. Telomerase is composed of a TERT (telomerase reverse transcriptase protein) and telomerase RNA. As we age, telomeres shorten since most human cells do not express telomerase. If telomeres grow too short, it triggers a cell-cycle arrest known as senescence, which can ultimately result in cell death. On the other hand, >85% of human cancers show ...

Effects Of Hyperbaric Oxygen Therapy On Intraocular Pressure In Dogs, Sierra Ott, Lauren Mirus

2021 Celebration of Student Scholarship - Poster Presentations

Hyperbaric oxygen therapy (HBOT) is a method in which pressurized oxygen is used to improve oxygen delivery to tissues. This treatment has been found to be effective in a variety of disorders in human and animal medicine, however it is underutilized in small animal medicine, in part because veterinary professionals may not be adequately familiar with how it works and when it is worthwhile. There has been hesitancy to utilize this method of treatment due to the fear of the unknowns, one example being a potential for an increase in intraocular. The mission of this project was to expand knowledge ...

Comparing Growth Of Mutant Strains Of Acinetobacter Baumannii To Wild Type After Treatment With Mitomycin C, Kaylee Compton, Deborah Cook, Janelle Hare

2021 Celebration of Student Scholarship - Poster Presentations

In Acinetocbacter baumannii bacteria, an error-prone DNA damage repair response is induced by the self-cleavage of the UmuDAb protein. Previous experiments indicating that a ddrR mutant becomes growth sensitive after DNA damage suggested that ddrR is also involved in this process. To explore this relationship, eight mutant strains of A. baumannii were made with different combinations of mutations in either ddrR and/or the adjacent gene, A1S_3662. Our experiment compared the growth of wild type cells to strains containing various mutations: DC4 (no gene mutations, just an antibiotic resistance marker, Kanr), DC5 (stop codon mutation in ddrR), and DC6 (both ...

Relation Among Potential Predictors Of Drug Abuse Risk In Rats, Emma Brock, Wesley White

2021 Celebration of Student Scholarship - Poster Presentations

Animal models have been used to investigate behavioral processes and mechanisms that underlie addiction. A variety of measures have been developed for rats that are modest predictors of drug abuse risk. The purpose of this pilot study was to begin to assess whether several established and potential measures of drug abuse vulnerability were correlated. The subjects were eight adult male Wistar rats. The rats were run on procedures that yielded measures of anxiety, sensation seeking, short term responsive to acutely administered drug, and sensitivity to conditioned stimuli. These measures were correlated with a potential new measure of drug abuse vulnerability ...


Identification Of Kentucky Land Snail Species, Tessa Whalen, Allen Risk Apr 2021

Identification Of Kentucky Land Snail Species, Tessa Whalen, Allen Risk

2021 Celebration of Student Scholarship - Poster Presentations

Land snails are members of the Phylum Mollusca and the Class Gastropoda. The importance of land snails to their native ecosystems has been greatly underestimated and understudied. For example, land snails play a huge role in the cycling of micronutrients in their ecosystems, they are active in the dispersal of plant seeds and fungal spores, and they have been shown to be bioindicators for vertebrates of conservation concern. They also contribute to the ecosystem by leaving their shells behind when they die, which is then used as a source of calcium carbonate by many species, and used in the formation ...

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

2021 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, the free 3’ ends cannot be fully copied. Unchecked ...
