Undergraduate Research Symposium Posters

Astronauts will face harmful stressors, such as galactic cosmic radiation (GCR) and sleep fragmentation (SF), on a three-year space flight mission to Mars and back. Astronauts perform skilled reach-to-grasp behaviors on these missions, including interacting with controls to navigate the spacecraft. Recent work has shown that GCR and SF disrupt skilled reach-to-grasp behavior in rodent models; however, the underlying nature of these deficits is unknown. To determine if tactile sensation and proprioceptive feedback contribute to these impairments, this study evaluated the effects of radiation and SF exposure on memory and sensorimotor discrimination in a rodent model. Twenty-one outbred Wistar, retired …

Development And Migration: A Case Study Of Agricultural Households In Northern Ghana, Otoniel Ramos

Undergraduate Research Symposium Posters

This study explores the intricate relationship between economic development and migration patterns in Northern Ghana's agricultural communities. Utilizing data from the EGC-ISSER Ghana Socioeconomic Panel Survey, the analysis focuses on the economic motivations driving migration, considering factors such as urbanization and economic growth. The findings reveal that while urbanization and economic prosperity individually decrease migration, in line with the assumptions of the human capital models of migration, their interaction significantly increases it, suggesting that growing wealthy urban centers; the emergence of new; or the growth of smaller urban centers (made possible due to economic growth) offer enhanced opportunities that attract …

DBPs are formed when chemical disinfectants react with organic and inorganic substances naturally present in water. The targeted DBPs for adsorption include trihalomethanes, haloacetic acids, haloacetonitriles, and nitrosamines. An example of high concentration DBP formation is during emergency chlorination, where excess …

Inter-Rater Reliablility Of Sharp Wave Ripple Detection In Recently Trained Experts, Orlando Montiel, Gage Pompa, Yader Gomez, Talha Soluoko

Undergraduate Research Symposium Posters

Sharp wave ripples (SWR) are a brain phenomenon that originate in the hippocampus, a region crucial for memory and learning. These events occur during periods of rest or slow-wave sleep and are characterized by fast oscillatory bursts (150-250Hz) and are thought to be important for the brain to consolidate memory. SWR are believed to facilitate the transfer of information from the hippocampus to the cortex, strengthening synaptic connections & enabling long-term memory storage. Accurate detection & assessment of SWRs is essential for advancing how the brain processes and stores information.

This study examines the accuracy/consistency of SWR image selection and …

Mitochondrial Heteroplasmy Improves Risk Prediction For Myeloid Neoplasms, Yun Soo Hong, Sergiu Pasca, Wen Shi, Daniela Puiu, Nicole J Lake, Monkol Lek, Meng Ru, Megan L Grove, Anna Prizment, Corinne E Joshu, Elizabeth A Platz, Eliseo Guallar, Dan E Arking, Lukasz P Gondek

Faculty, Staff and Student Publications

Clonal hematopoiesis of indeterminate potential is the primary pathogenic risk factor for myeloid neoplasms, while heteroplasmy (mutations in a subset of cellular mitochondrial DNA) is another marker of clonal expansion associated with hematological malignancies. We explore how these two markers relate and influence myeloid neoplasms incidence, and their role in risk stratification. We find that heteroplasmy is more common in individuals with clonal hematopoiesis of indeterminate potential, particularly those with higher variant allele fractions, multiple mutations, or spliceosome machinery mutations. Individuals with both markers have a higher risk of myeloid neoplasms than those with either alone. Furthermore, heteroplasmic variants with …

Inferring Tumor Purity Using Multi-Omics Data Based On A Uniform Machine Learning Framework Motp, Qiqi Lu, Zhixian Liu, Xiaosheng Wang

Faculty, Staff and Student Publications

Existing algorithms for assessing tumor purity are limited to a single omics data, such as gene expression, somatic copy number variations, somatic mutations, and DNA methylation. Here we proposed the machine learning Multi-omics Tumor Purity prediction (MoTP) algorithm to estimate tumor purity based on multiple types of omics data. MoTP utilizes the Bayesian Regularized Neural Networks as the prediction algorithm, and Consensus Tumor Purity Estimates as labels. We trained MoTP using multi-omics data (mRNA, microRNA, long non-coding RNA, and DNA methylation) across 21 TCGA solid cancer types. By testing MoTP in TCGA validation sets, TCGA test sets, and eight datasets …

Mutations in the CLCNKB gene (1p36), encoding the basolateral chloride channel ClC-Kb, cause type 3 Bartter syndrome. We identified a family with a mixed Bartter/Gitelman phenotype and early-onset kidney failure and by employing a candidate gene approach, identified what we believe is a novel homozygous mutation (CLCNKB c.499G>T [p.Gly167Cys]) in exon 6 of CLCNKB in the index patient. We then validated these results with Sanger and whole-exome sequencing. Compared with wild-type ClC-Kb, the Gly167Cys mutant conducted less current and exhibited impaired complex N-linked glycosylation in vitro. We demonstrated that loss of Gly-167, rather than gain of a mutant Cys, …

Globally, potato (Solanum tuberosum) is a key staple food crop. In Kenya, it is the second most important food crop after maize. Among the various constraints to potato production are plant-parasitic nematodes. In particular, root-knot nematodes (Meloidogyne spp.) are a significant impediment to potato production, suppressing yield and reducing the quality of harvested tubers. The current study was undertaken to evaluate the efficacy of a lignocellulose fibre matrix (banana paper) either impregnated with a chemical or drenched with a biologically-based nematicide for the management of root-knot nematodes on potatoes, in Kenya. The experiment was conducted in both field and pot …

Levodopa (L-DOPA) treatment is a clinically effective strategy for improving motor function in patients with ischemic stroke. However, the mechanisms by which modulating the dopamine system relieves the pathology of the ischemic brain remain unclear. Emerging evidence from an experimental mouse model of ischemic stroke, established by middle cerebral artery occlusion (MCAO), suggested that L-DOPA has the potential to modulate the inflammatory and immune response that occurs during a stroke. Here, we aimed to demonstrate the therapeutic effect of L-DOPA in regulating the systemic immune response and improving functional deficits in mice with ischemia. Transient MCAO led to progressive degeneration …
