Dual Colorimetric And Fluorometric Detection Of Hydrogen Peroxide In Aqueous Samples, Nathan F. Surles, Kaitlin A. Edwards Apr 2025

Dual Colorimetric And Fluorometric Detection Of Hydrogen Peroxide In Aqueous Samples, Nathan F. Surles, Kaitlin A. Edwards

ATU Scholars Symposium

In this project, a simple, inexpensive colorimetric and fluorometric method for determining hydrogen peroxide in aqueous samples is described. In this method, aryl boronic acid is de-protected to produce a red dye that absorbs and emits in the red/near infrared region of the electromagnetic spectrum. Upon deprotection by the hydrogen peroxide, an intramolecular charge transfer occurs between a strong phenolate donor and a TCF acceptor to produce the strong absorption and bright fluorescence. This allows naked eye detection of hydrogen peroxide within seconds in water under physiological conditions. The detection limit is impressive and falls in the sub-micromolar (µM) range. …

Ecosystem Stability In The Late Cretaceous Preceding The Chicxulub Impact, Anna Gamal, Anthony Uriarte

Undergraduate Research and Engagement Symposium

The K-Pg mass extinction significantly altered the course of life on Earth— nearly 75% of all life went extinct. However, we still do not know the exact cause of this extinction event. There are two hypotheses: 1) the extinction was created solely by the Chicxulub meteor impact; 2) the global ecosystem was already in decline before the meteor. Here, we test these hypotheses using fossils from the Lance Creek Formation of Wyoming. We gathered data on taxonomic richness, abundance, evenness and compared our data to historically well-sampled sites. Continued testing on these two hypotheses will allow us to gather support …

Comparative Population Genetics Of Astragalus Lentiginosus And Its Toxic Fungal Endophyte, Zoe Smutko Apr 2025

Comparative Population Genetics Of Astragalus Lentiginosus And Its Toxic Fungal Endophyte, Zoe Smutko

Undergraduate Research and Engagement Symposium

Astragalus L. (Leguminosae, Fabaceae) is the most species-rich plant genus in the world, with roughly 3,000 species. These “locoweeds” cause grazing animals to suffer from chronic neurological wasting disease leading to an estimated loss of 100 million dollars annually. These conditions are the result of the toxin swainsonine, which is present in certain species of Astragalus. Swainsonine is not produced by the plant but is a secondary metabolite synthesized by mutualistic fungal endophytes. However, natural swainsonine levels are variable both across and within Astragalus species causing some questions about why some Astragalus varieties exhibit this mutualism and others do not.

Prenatal Stress Effects On Sex Differences In Recognition Memory And Synaptic Expression Of Ampa-Type Glutamate Receptors, Rumyr Sobrepena Apr 2025

Prenatal Stress Effects On Sex Differences In Recognition Memory And Synaptic Expression Of Ampa-Type Glutamate Receptors, Rumyr Sobrepena

Undergraduate Research and Engagement Symposium

Prenatal stress (PRS) increases the risk of cognitive deficits in male but not female offspring. This study investigates sex-specific effects of PRS on RNA editing, AMPA receptor expression, and dendritic spine density in the dorsal CA1 hippocampus—critical for memory. Behavioral assays revealed impaired recognition memory in PRS males only. We hypothesize that reduced RNA editing and synaptic AMPA receptor localization underlie these deficits. Through immunohistochemistry, confocal imaging, and qPCR, we will assess correlations between molecular alterations and cognition. Findings may uncover mechanisms of female resilience to PRS and identify targets for treating neurodevelopmental disorders marked by cognitive impairments.
