Studying The Genes And Conditions That Influence Root Development, Tessa Holtkamp, Hannah Ordonez Webb
Studying The Genes And Conditions That Influence Root Development, Tessa Holtkamp, Hannah Ordonez Webb
Undergraduate Research Symposium
Root development in plants is essential for their survival and understanding how hormones influence their development can explain how plants grow under different circumstances. Researching how Indole-3-butyric acid (IBA), a hormone that induces root production, affects the plant model Arabidopsis thaliana helps explain the hormone's effect in agricultural crop systems. To understand root pathways, we performed assays on mutant lines of Arabidopsis by growing plants on varying concentrations of IBA. For wild-type and mutant lines, phenotyping experiments like branching of roots, lengths of stems, and root length were conducted along with PCR and restriction digest genotyping experiments to compare their …
Effects Of Beauveria Bassiana On The Mortality And Thorax Width Of Bombus Impatiens Colonies, Bri Petty
Effects Of Beauveria Bassiana On The Mortality And Thorax Width Of Bombus Impatiens Colonies, Bri Petty
Undergraduate Research Symposium
Pesticides are widely used to protect against unwanted insects, but risk assessments of the effects on pollinators have traditionally only been applied on an individual level, not a population level. This has allowed many pesticides to be approved without the knowledge of sub-lethal effects, such as life history characteristics and population structure to name a few. The biopesticide BotaniGard, containing the entomopathogenic fungus Beauveria bassiana, has previously been thought to be safe for non-targeted insects, but recent studies have found it to have significant negative effects on pollinators. Such negative effects can include decrease in longevity and odorant responsiveness with …

Comparing Sucrose Preference Between Colonies Of Bombus Impatiens, Kevin R. Corrigan, Becky Hansis-O'Niell, Aimee Sue Dunlap
Undergraduate Research Symposium
Current studies in nectar concentration preference generally take the form of a static laboratory experiment in which a multitude of feeders provide a constant source of nectar in differing concentrations and data is collected on which one is preferred most by bees. Studies like these are important because they seek to gain an understanding of bee foraging patterns. Having a strong biological understanding of these organisms better prepares us to combat issues regarding conservation should they occur. Here, we conduct an analysis on the foraging patterns of two colonies of Bombus impatiens (B. Impatiens) with data gathered from fixed ratio …

The HE program consisted of breathing and postural awareness exercises in addition to 5 basic HE poses performed three times each. Dynamic neuromuscular control …
Surveys Of Aphonopelma Hentzi In Missouri: Conservation Efforts Through Population, Genetics, And Habitat Studies, Anderson B. Spencer Mr., Becky Hansis-O'Niell
Surveys Of Aphonopelma Hentzi In Missouri: Conservation Efforts Through Population, Genetics, And Habitat Studies, Anderson B. Spencer Mr., Becky Hansis-O'Niell
Undergraduate Research Symposium
Aphonopelma hentzi and other tarantula species are greatly understudied organisms. In the Missouri regions there is little knowledge on their mating patterns, gene diversity, or population sizes. The focal glades in this experiment display regional fragmentation, which could prevent tarantulas from traveling and mating between regions of their glades. Due to the lack of knowledge surrounding them, methods for determining gene diversity are harmful to the organism. Our recent work has shown that it is possible to extract genetic information from the molts of burrowing tarantulas. This will allow us to safely determine the lineages and interbreeding patterns of the …
The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr
The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr
Undergraduate Research Symposium
This presentation focuses on the effect of caffeine on bee behavior using behavioral pharmacology methodologies. Researchers trained bumblebees to drink out of artificial flowers, then administered sucrose nectar or caffeinated sucrose nectar during a schedule of progressive and fixed ratios. The finding suggests that caffeine did increase the number of rewards during the fixed ratio, but not in the progressive ratio. However, research is still ongoing as bees continue to be tested..

Changes In Brain Activity Immediately Post-Exercise Indicate A Role For Central Fatigue In The Volitional Termination Of Exercise, Grant Chesbro, Cameron Owens, Melody Reese, Lisa Destefano, J. Mikhail Kellawan, Daniel Larson, Michael Wenger, Rebecca Larson
International Journal of Exercise Science
International Journal of Exercise Science 17(1): 220-234, 2024. Electroencephalography (EEG) allows for the evaluation of real time changes in brain (electrocortical) activity during exercise. A few studies have examined changes in electrocortical activity using stationary cycling, but the findings have been mixed. Some of these studies have found increases in brain activity following exercise, while others have found decreases in brain activity following exercise. Hence, it is of importance to identify post-exercise changes in brain activity. Sixteen healthy, untrained subjects (8 males; 8 females) participated in the study. All 16 participants performed a graded exercise test (GXT) to volitional exhaustion …
Finding Gene Candidates That Interact With Mara To Control Hila Expression In Salmonella Enterica, Kylee Hempel
Finding Gene Candidates That Interact With Mara To Control Hila Expression In Salmonella Enterica, Kylee Hempel
Undergraduate Research Symposium
Salmonella is a well-known pathogen that is linked to food born illnesses common around the world. This pathogen can cause symptoms such as fever, diarrhea, and chills in the host. One of the mechanisms Salmonella uses to infect its host’s epithelial cells deals with the S. typhimurium pathogenicity island 1 (SPI-1). Expression of SPI-1 is activated in response to environmental signals that correlate with the ileum of the small intestine (low oxygen, high osmolarity, and neutral pH). HilA is the central activator of the SPI-1 complex, and when the transcription factor, MarA, is over-expressed in Salmonella, hilA transcription is …
Recovering Ancient Dna Using The Polymerase Chain Reaction, Rose Jennings
Recovering Ancient Dna Using The Polymerase Chain Reaction, Rose Jennings
Undergraduate Research Symposium
Investigations into aDNA offer a window into the past that modern DNA and paleontological studies alone cannot provide and help address the evolution and connections between hominids, domestication timelines, the analysis of populations over time, and general diversity. Progress in aDNA research has been inherently technology-driven, with modern molecular biology methods, such as the inventions of Polymerase Chain Reaction (PCR) and Next Generation Sequencing (NGS), substantially increasing the analysis possibilities of aDNA. My research this semester has taken me along two parallel paths of investigation: literary research into aDNA and practical exposure to the laboratory techniques used in its analysis. …

Investigation Of Alzheimer’S Amyloid-Β Protein Aggregation With A New Fluorescent Dye., Emma Alberty
Undergraduate Research Symposium
Alzheimer’s Disease (AD) is the most common form of dementia characterized by the impairment of at least two brain functions such as memory loss and judgement. AD is a progressive illness that can last as many as 20 years. AD is largely considered to be caused by the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. A better understanding of the structure and function of these plaques may lead to clearer understanding of the disease. To analyze amyloid plaques, aggregation assays are often used. During these assays we begin with monomer and place the sample in biological conditions to …

Biology Faculty Research
Food waste is a major issue that is increasingly affecting our environment. More than one-third of food is wasted, resulting in over $400 billion in losses to the U.S. economy. While composting and other small recycling practices are encouraged from person-to-person, it is not enough to balance the net loss of 80 million tons per year. Currently, one of the most promising routes for reducing food waste is through microbial fermentation, which can convert the waste into valuable bioproducts. Among the compounds produced from fermentation, 2,3-butanediol (2,3-BDO) has gained interest recently due to its molecular structure as a building block …

Dissecting Mechanisms Underlying The Cap1 Functions In The Matrix Adhesion And Proliferation Of Cancer Cells, Auburn Ramsey
Student Theses and Dissertations
Cancer is a significant health burden as the second leading cause of death worldwide. Metastasis-driven fatality accentuates the need for novel strategies to impede cancer dissemination. The cytoskeletal protein CAP1 plays a pivotal role in linking cell signals to control the actin cytoskeleton, cell adhesion, and proliferation – critical aspects of both metastasis and proliferative transformation. While the role of CAP1 in the actin cytoskeleton is well elucidated, the CAP1 functions in adhesion and proliferation are cell type-specific with poorly understood molecular mechanisms. This study seeks to unravel how CAP1 executes functions in these processes, aiming to contribute to our …

Division of Nephrology Faculty Papers
Previous investigators have used various anti-HLA-F monoclonal antibodies (mAbs) to demonstrate that the tissue distribution of HLA-F is highly restricted. Notably, these mAbs differed in their immunodiagnostic capabilities. Specifically, mAbs Fpep1.1 and FG1 detected HLA-F intracellularly in B cells but not on the cell surface, whereas mAb 3D11 detected HLA-F on the cell surface. The presence of HLA-F on T cells was recognized by mAb FG1 but not by mAb Fpep1.1. mAb 3D11 detected HLA-F on the cell surface of activated B cells and on peripheral blood lymphocytes, but not on the normal cells. Importantly, mAb 3D11 revealed that HLA-F …

Mental workload can be assessed using electrophysiological measures of brain activity, such as electroencephalography (EEG). EEG signals reveal cortical electrical activity. This cortical activity was recorded using specialized headsets. The focus of this research was to study cognitive performance (CP) in four pilots during simulated suborbital flights under nominal day and night profiles and under contingency day and night profiles. A 14-channel EMOTIV EEG headset measured the participants' brain activity while they flew simulated flights in a Suborbital Spaceflight Simulator (SSFS). Several sessions of EEG data were recorded from each subject, and feature extraction was applied. Data revealed that real-time …
