Methamphetamine Activates Microglia And Increases Production Of Pro-Inflammatory Chemokine C-C Ligand 2, Colton Bredenkamp

Theses/Capstones/Creative Projects

Methamphetamine (meth) use continues to increase in the United States despite the apparent health risks that involve neuroinflammation and brain damage. Because neuroinflammation underlies several substance-use and neurological disorders, we investigated whether microglia, the resident immune cells in the brain, are activated and consequently increase production of pro-inflammatory chemokines such as C- C chemokine ligand 2 (CCL2) in the presence of increasing amounts of meth. To address this, we exposed immortalized microglia cells (IMG) isolated from mature mouse brains to increasing concentrations of meth (0, 10, 50, 100, 500 µM) and analyzed for the expression levels of activation markers (CD11b …

Determining Efficacy Of Check/Solid Stimuli Pair Vs Light/Dark Stimuli Pair For Pavlovian Fear Learning In Zebrafish (Danio Rerio), Kortney Johnson

Theses/Capstones/Creative Projects

Learning is a survival skill because it allows organisms to recall vital details about their habitats. Associative learning is another of those skills, the ability to pair two different stimuli in memory and associate them together upon recall. It has been studied in zebrafish with Pavlovian fear learning used as a methodology. Previous studies have utilized Check/Solid patterning, however, there are no published studies exploring alternative stimuli that could be effective in aversive learning. This study sought to determine if Check/Solid was the most effective at inducing aversive learning or if Light/Dark would be more efficient, due to zebrafish’s natural …

How Is International Orchid Trade Regulated, And How Effective Are Those Regulations?, Madeline Roubik

Mary Ann Bolton Undergraduate Research Award

When investigating the trafficking of wild species, animals are often considered before plants (Phelps et al. 2015). This is especially detrimental to members of the orchidaceae family, which are victims of an extensive illegal trade. It spans the entire globe but is especially concentrated in Southeastern Asia (Phelps et al. 2015). When regarding legislation, however, orchidaceae species are some of the most protected in the world. International legislation such as CITES restricts the movement of endangered orchidaceae across borders (Hinsley 2018). The 1992 Convention on Biodiversity (Lawson et al. 2019) also has policies regarding international orchid trade. National laws regulate …

Examining The Relationship Between Manning's Roughness Coefficient And Stage, Henry Holtkamp

Biological and Agricultural Engineering Undergraduate Honors Theses

This paper uses LOESS regression to predict Manning's roughness coefficient to calculate flows in natural stream channels. Manning's roughness coefficient can introduce variability into Manning's equation, potentially destabilizing results. Utilizing LOESS to find n based on backcalculated n from collected discharge vs. stage information is the best way to acquire accurate Manning's roughness coefficient values at a variety of flows. Book values tend to drastically overestimate which can have wide-ranging implications for water allocation, flood management, maintaining environmental flows, and maintaining water quality.

Thamnophis And Their Toxic Relationship: Testing For Intraspecific Venom Variation In Common Garter Snakes, Thamnophis Sirtalis, Grace E. Coppinger

Honors Theses

Venomous species, particularly snakes, have captured human interest for decades. Over the last few decades, scientists have studied front-fanged venomous snakes to develop drugs, treat human disease, better manage snakebites, and answer ecological and evolutionary questions. However, these studies have largely ignored rear-fanged snakes which account for two-thirds of total snake species, despite only accounting for 23 % of published venom gland transcriptomes. To address the lack of knowledge about rear-fanged snake (RFS) venom, we sequenced the messenger RNA from the Duvernoy’s gland in 9 male and 10 female Common Garter Snakes, Thamnophis sirtalis. I produced the first Duvernoy’s venom …

Evaluating The Integration Of Traditional And Western Medicine In Rural Ghana: The Role Of Healers And The Government, Teresa Nicole Lemon

Poster Presentations

A question of pressing importance for the healthcare system in Ghana is the integration between biomedicine, which is unreachable for many rural citizens, and traditional medicine, which fills in the gaps in access for rural and non-rural citizens seeking care and is utilized by 70% of the population. The WHO promotes integrated health systems and created strategies to assist governments in their efforts.

The Ghanaian government did create policies to aid in integration, but their attempt to integrate was unsuccessful. This, along with other factors, has led some scholars to consider the government’s efforts as “tokenistic”; however, they do not …
