Climactic Transition And Loess Transport In The White River Badlands, South Dakota, John Nichols, Victor Pomales Pinto, Iyanla Reid, Lillie Suthers

Undergraduate Student Symposium

The Great Plains is one of the most important agricultural regions in the world. However, the semiarid climate makes the region vulnerable to drought and climate change. Safeguarding this critical resource will depend on forecasting the timing and magnitude of climatic transitions and drought events. This study investigates dust deposition during the climate transition from the last glacial period into the modern interglacial period (Late Pleistocene to Holocene) in the White River Badlands (WRB), South Dakota. Preliminary radiocarbon evidence indicates significant dust deposition began around 25,000 years ago (25 ka), coinciding with the coldest time during the last glacial period …

Synthesizing Ferrocene Bipyridine Adducts For The Creation Of New Metal Based Photosensitizing Complexes, Gabrielle Spankus, Jarlynn Ramirez

Undergraduate Student Symposium

Metal-based photosensitizers commonly use bipyridine molecules and their ligands. Their absorption and chemical properties can be tuned through substitutions. This study synthesized a ferrocene appended 2,2 -bipyridine dimer (Fc-bipy2-Fc) using palladium(0)-catalyzed Suzuki-Miyaura cross coupling reaction to create new photosensitizing molecule that could further complex with metals such as ruthenium to enhance photophysical and electronic properties. The product was purified by flash chromatography and characterized by NMR, FTIR, UV-Vis, and fluorescence spectroscopy.

Comparative Genomics Across Ganoderma Species To Identify Secondary Metabolite Clusters With Cytoxic Properties, Omobolanle Ayangade, Abril Chao, Emily Abraham, Maya Pasapuleti, Fatima Muhammad, Rajendra Pangeni Ph.D., Braham Dhillon Ph.D.

Undergraduate Student Symposium

Fungi in the genus Ganoderma have been widely studied in Chinese culture for their medicinal properties and promoting overall health and longevity. Our prior work on eight Ganoderma species showed that they contain Secondary Metabolite Clusters (SMCs) that code for multiple terpenes, betalactones, and ribosomally synthesized and post-translationally modified peptides (RiPPs). These compounds are well known for their cytotoxic and anticancer potential. A specialized bioinformatics analysis tool, antiSMASH1, was used to identify and annotate SMCs that produce anticancer compounds in the eight Ganoderma genomes. To test the results obtained from the bioinformatics analysis, fungal extracts were prepared from G. lucidum …

How Framing Medical Treatments Affects Patient Risk-Taking Behavior, Deepthi Prince

Undergraduate Student Symposium

The framing effect, a psychological phenomenon in which decision-making is influenced by how information is presented, is crucial in understanding human behavior under risk. This study examined the influence of positive versus negative framing on risk-taking behavior in a medical context. This study hypothesized that participants exposed to positive framing (emphasizing success) would exhibit lower levels of risk-taking behavior, while participants exposed to negative framing (emphasizing failure) would display higher levels of risk-taking behavior. Participants chose between two hypothetical treatment options for a life-threatening illness, with framing manipulated accordingly. Decision-making was assessed through participant preference, confidence, and awareness of cognitive …

Investigation Children's Sensory Responses To Stressful Stimuli Using Eye Tracking Technology, Pearly Trivedi

Undergraduate Student Symposium

Children diagnosed with Autism Spectrum Disorder (ASD) often have a challenging time navigating stressful situations. This can be connected to the differences in emotional regulation and sensory processing when compared to children who are neurotypical. Despite the research performed on ASD, there seems to be a gap in understanding how effectively children with ASD are able to reconnect with reality after experiencing an overstimulating environment. To bridge the gap, this study was performed to use advanced eye-tracking technology to gather objective data on key indicators such as facial expressions, pupil dilation, and eye movement patterns. By comparing the responses of …

Modeling Nicotine, At-1001, & Varenicline At The α3β4 Nicotine Acetylcholine Receptor, Japji G. Madan, Mourya Khandai, Andersen Cheong

Undergraduate Student Symposium

The escalating prevalence of nicotine addiction among adolescents has been linked to the increasing use of e-cigarettes, known as vapes. Approximately, 1.63 million students in the United States (ages 11-18) use vapes, reflecting a concerning trend of nicotine dependence among adolescents. Activation of the nicotine acetylcholine receptor (nAChR) can modulate the dopamine pathways in the mesolimbic system, increasing nicotine addictive behavior. A 3-D printed molecular model was prepared using the PDB file 6PV7, to explore the molecular dynamics of one of the binding sites between subunits A and B of the pentameric receptor. This model highlights the binding of two …

Playing Stereoscopic Video Games Enhances The Precision But Not The Accuracy Of Depth Perception, Charlene Li, Nada Bleibel, Lara Cereminati, Yingzi Luo, Betty Z. Li Ph.D., Dennis M. Levi Ph.D., Sandy W. Chat

Undergraduate Student Symposium

Purpose. We recently reported that playing immersive video games in a three-dimensions (3D) environment boosts stereo vision in young adults with normal vision. Here we asked whether the improvement in stereoscopic acuity (precision) was the result of a reduced disparity pedestal, as indicated by a decreased subjective depth bias (accuracy).

Methods. Twenty-one university students with normal visual acuity and stereoacuity were recruited. All of them had limited previous video game experience, and none had ever played 3D video games. Participants were required to play stereoscopic 3D video games for a total of 40 hours, 2 hours per session, over 4-5 …

Psychedelic Substituted Phenethylamine Alters Human Neural Progenitor Cell Morphology, Proliferation, And Survival, Omar E. Saleh, Grace K. Wong, Chase A. Gonzales, Mark Apterman, Laury Pierre, Stacey Doret, Isaac Hai, Travis J.A. Craddock

Undergraduate Student Symposium

Examining how psychedelic substituted phenethylamines affect neural plasticity is key to understanding harms and potential medical implications of recreational drugs. The microtubule cytoskeleton has been proposed to modulate the effects of phenethylamines as a downstream effector and through scaffolding mechanisms. Microtubules play a crucial role in neurite outgrowth, protein transport, and synaptic stability in cells. Our group has shown that specific psychedelic substituted phenethylamines (25B-NBF, 25C-NBF, and DMBMPP) alter microtubule formation in a dose-dependent manner. As these phenethylamines limit microtubule capacities, they may impact cytoskeletal-mediated neural plasticity. This study’s purpose is to determine if substituted phenethylamines, 25B-NBF, 25C-NBF, and DMBMPP …

Resilience And Its Effects On Psychological Well Being During The Covid-19 Pandemic, Taylor Reinsel

Undergraduate Student Symposium

Stressors and trauma in life are unavoidable. However, the way we respond and adapt to them can be within our control. This response differs from person to person, but there are factors that can influence the likelihood of an individual rebounding from a crisis, as well as factors that can put them at a higher risk of developing mental illness. One of the main factors that influences Psychological Well Being is the presence of Resilience. The main goal of this study was to examine how factors of Resilience relate to Psychological Well Being and COVID-19 Well Being during the COVID-19 …

Sgi-1027 Small Molecule Inhibits Dnmt And Promotes P21-Mediated Apoptosis Via Epigenetic Alterations In Sk-N-Sh Neuroblastoma Cells, Sadhna Seth, Anika Singh, Shyam Sundar Jaganathan Ph.D.

Undergraduate Student Symposium

Neuroblastoma is an aggressive childhood cancer originating from neural crest cells. Treatment for high-risk neuroblastoma includes chemotherapy. Emerging evidence indicates that DNMT inhibitor codenamed SGI-1027 may facilitate cell cycle arrest and induce apoptosis by modulating cell cycle regulatory pathways. Therefore, we hypothesize that SGI-1027 treatment could lead to apoptosis mediated cell death in SK-N-SH cells through the upregulation of p21 transcription.

This study investigated whether SGI-1027, a DNA methyltransferase inhibitor, causes DNA methylation and upregulation of p21 through a p53-independent pathway, which could lead to cell cycle arrest and intrinsic-pathway mediated apoptosis in SK-N-SH cells. To assess the effects of …

Spliceosomal Modulation Induces Immunogenicity Of Melanoma Cells And In Vivo Immune Response, Sadeeshkumar Velayutham, Shweta Shah, Tulsi Desai, Keiran S.M. Smalley Ph.D., Aveta Singh Ph.D., Jun Yong Choi Ph.D.

Undergraduate Student Symposium

Melanoma is an aggressive skin cancer with high mortality rates, often driven by BRAF and NRAS mutations. While targeted therapies like Vemurafenib have improved outcomes in BRAF-mutant melanoma, resistance and adverse effects limit their long-term efficacy. There is an urgent need for novel therapeutic approaches to overcome these challenges. This study investigates the efficacy of novel anti-melanoma compounds, 2155-14 and 2155-18, targeting spliceosomal proteins, in a xenograft model derived from the A375 BRAF/NRAS double mutant cell line. Seven-week-old mice were implanted with A375 BRAF/NRAS mutant cells and treated with 2155-14 or 2155-18. Treatments were administered subcutaneously thrice weekly. Tumor growth …

Targeting The Renin-Angiotensin System For The Treatment Of Cerebral Amyloid Angiopathy, Ariana Hernandez, Chana Vogel, Victoria Pulido-Correa, Natalia Noto, Yazmin Restrepo, Shay Moen, Julianna Bonetti

Undergraduate Student Symposium

Cerebral amyloid angiopathy (CAA), the accumulation of amyloid proteins in the cerebral vasculature, can increase the risk of stroke, vascular cognitive impairment, and dementia. CAA is highly comorbid with Alzheimer’s disease and contributes to Alzheimer’s pathology by affecting the clearance of amyloid from the brain. Epidemiological studies suggest that certain renin-angiotensin system-targeting drugs, commonly used for the treatment of hypertension, decrease the risk of dementia. This study assesses whether two FDA-approved RAS-targeting drugs: telmisartan [a brain-penetrant angiotensin receptor blocker (ARB)], and lisinopril [a brain-penetrant angiotensin-converting enzyme (ACE) inhibitor]; can be repurposed to mitigate CAA, associated neuropathologies, and cognitive decline in …

Undergraduate Student Symposium

Aggressive cancers are particularly challenging due to their rapid growth, ability to adapt, and resistance to single therapies. Combination therapies or a multipronged approach can increase tumor cell killing and limit the development of drug resistance. The potential of combining conventional chemotherapy with targeted therapies was investigated. To determine the best drug combinations, viability assays using an 8 x 8 dose response matrix format (checkerboard) with small-step serial dilutions of cytotoxic and targeted drugs was performed. The resulting viability data, as determined by MTS assay, was analyzed using the web application SynergyFinder. The results indicated that the combined drug treatment …
