Pollen-Mediated Gene Flow From Herbicide-Resistant Yellow Corn To Non-Genetically Engineered Food-Grade White Corn, Mandeep Singh, Vipan Kumar, Stevan Z. Knezevic, John L. Lindquist, Suat Irmak, Santosh Pitla, Amit J. Jhala

Department of Agronomy and Horticulture: Faculty Publications

Nebraska is the number one producer of food-grade white corn in the United States. Pollen-mediated gene flow (PMGF) from genetically engineered high alpha-amylase corn, known as Enogen corn, to food-grade white corn can have undesirable outcomes. Alpha-amylase can convert starch in white corn to sugar during or after its processing, degrading the quality of processed products. Thus, proximity to Enogen corn puts white corn production at risk. The objectives of this study were to evaluate the PMGF from herbicide-resistant yellow corn to food-grade white corn and assess the significance of wind speed and direction. Field experiments were set up using …

Effects Of Stroboscopic Vision On Depth Jump Motor Control: A Biomechanical Analysis, Kenneth D. Harrison, Christopher J. Dakin, Anne Z. Beethe, Talin Louder

Kinesiology and Health Science Faculty Publications

Researchers commonly use the 'free-fall' paradigm to investigate motor control during landing impacts, particularly in drop landings and depth jumps (DJ). While recent studies have focused on the impact of vision on landing motor control, previous research fully removed continuous visual input, limiting ecological validity. The aim of this investigation was to evaluate the effects of stroboscopic vision on depth jump (DJ) motor control. Ground reaction forces (GRF) and lower-extremity surface electromyography (EMG) were collected for 20 young adults (11 male; 9 female) performing six depth jumps (0.51 m drop height) in each of two visual conditions (full vision vs. …

Stereo-Video Landers Can Rapidly Assess Marine Fish Diversity And Community Assemblages, Kinsey E. Matthews, Ryan T. Fields, Kathleen P. Cieri, Jacklyn L. Mohay, Mary G. Gleason, Richard M. Starr

Faculty Research, Scholarly, and Creative Activity

Climate change and anthropogenic stressors affect the distribution, abundance, and diversity of fish communities across the world. To understand rapidly changing biotic communities, resource managers need a method to quickly and efficiently document temporal and spatial changes in community assemblages across various spatial scales. In this study, we describe the use of new video lander tools to survey fish communities in rocky marine habitats on the continental shelf and slope in California, USA. We evaluate how fish diversity metrics determined by video surveys vary among geographically distinct areas. Our results demonstrate that species diversity, evenness, and richness vary spatially across …

Effects Of Diminazene Aceturate On Drosophila Melanogaster: A Lipidomic Analysis, Gabriela Suarez

USF Tampa Graduate Theses and Dissertations

Pesticides are agents designed to eradicate living organisms to preserve agricultural needs.¹ Today the most commonly used pesticides are termed “modern pesticides”, they are characterized by lower lipophilicity and limited stability, making them less time persistent in the environment. Among these modern pesticides are organophosphorus, urea, phenoxy alkanoic, triazine, chloroacetanilide, and glyphosate-based pesticides.² The issue faced with most of these pesticides is that they affect more than just the targeted pest and pose a danger to not only humans, but also entire ecosystems.^1,3,4 While there are many different types of pesticides, insecticides show the most variance and …

Summit-Fa: A New Resource For Improved Transcriptome Imputation Using Functional Annotations, Hunter J Melton, Zichen Zhang, Chong Wu

Faculty, Staff and Student Publications

Transcriptome-wide association studies (TWAS) integrate gene expression prediction models and genome-wide association studies (GWAS) to identify gene-trait associations. The power of TWAS is determined by the sample size of GWAS and the accuracy of the expression prediction model. Here, we present a new method, the Summary-level Unified Method for Modeling Integrated Transcriptome using Functional Annotations (SUMMIT-FA), which improves gene expression prediction accuracy by leveraging functional annotation resources and a large expression quantitative trait loci (eQTL) summary-level dataset. We build gene expression prediction models in whole blood using SUMMIT-FA with the comprehensive functional database MACIE and eQTL summary-level data from the …

Targeting the mitogen-activated protein kinase (MAPK) cascade in pancreatic ductal adenocarcinoma (PDAC) remains clinically unsuccessful. We aim to develop a MAPK inhibitor-based therapeutic combination with strong preclinical efficacy. Utilizing a reverse-phase protein array, we observe rapid phospho-activation of human epidermal growth factor receptor 2 (HER2) in PDAC cells upon pharmacological MAPK inhibition. Mechanistically, MAPK inhibitors lead to swift proteasomal degradation of dual-specificity phosphatase 6 (DUSP6). The carboxy terminus of HER2, containing a TEY motif also present in extracellular signal-regulated kinase 1/2 (ERK1/2), facilitates binding with DUSP6, enhancing its phosphatase activity to dephosphorylate HER2. In the presence of MAPK inhibitors, DUSP6 …

Using Chatgpt To Generate Gendered Language, Shweta Soundararajan, Manuela Nayantara Jeyaraj, Sarah Jane Delany

Conference papers

Gendered language is the use of words that denote an individual's gender. This can be explicit where the gender is evident in the actual word used, e.g. mother, she, man, but it can also be implicit where social roles or behaviours can signal an individual's gender - for example, expectations that women display communal traits (e.g., affectionate, caring, gentle) and men display agentic traits (e.g., assertive, competitive, decisive). The use of gendered language in NLP systems can perpetuate gender stereotypes and bias. This paper proposes an approach to generating gendered language datasets using ChatGPT which will provide data for data-driven …

Mapping Human Tissues With Highly Multiplexed Rna In Situ Hybridization, Kian Kalhor, Amanda Knoten, Joseph P Gaut, Sanjay Jain, Et Al.

2020-Current year OA Pubs

In situ transcriptomic techniques promise a holistic view of tissue organization and cell-cell interactions. There has been a surge of multiplexed RNA in situ mapping techniques but their application to human tissues has been limited due to their large size, general lower tissue quality and high autofluorescence. Here we report DART-FISH, a padlock probe-based technology capable of profiling hundreds to thousands of genes in centimeter-sized human tissue sections. We introduce an omni-cell type cytoplasmic stain that substantially improves the segmentation of cell bodies. Our enzyme-free isothermal decoding procedure allows us to image 121 genes in large sections from the human …

A Tough Bioadhesive Hydrogel Supports Sutureless Sealing Of The Dural Membrane In Porcine And Ex Vivo Human Tissue, Kyle C Wu, Benjamin R Freedman, Phoebe S Kwon, Matthew Torre, Daniel O Kent, Wenya Linda Bi, David J Mooney

Duncan NRI Faculty and Staff Publications

Complete sequestration of central nervous system tissue and cerebrospinal fluid by the dural membrane is fundamental to maintaining homeostasis and proper organ function, making reconstruction of this layer an essential step during neurosurgery. Primary closure of the dura by suture repair is the current standard, despite facing technical, microenvironmental, and anatomic challenges. Here, we apply a mechanically tough hydrogel paired with a bioadhesive for intraoperative sealing of the dural membrane in rodent, porcine, and human central nervous system tissue. Tensile testing demonstrated that this dural tough adhesive (DTA) exhibited greater toughness with higher maximum stress and stretch compared with commercial …

Intersectionalities Of Systematic Barriers Set Upon Underrepresented Students In Stem: Capturing The Potential Benefits Of Online Modality, Raiyasha Aiyanna Paris

University Honors Theses

The prevalence of racism and microaggressions in STEM disciplines within colleges presents significant hurdles to the academic success and well-being of underrepresented students. Microaggressions, encompassing subtle biases and stereotyping, have a cumulative impact, inducing heightened stress, diminished motivation, and reduced self-efficacy among minority students, thereby impeding cognitive functioning and hindering academic progress (Ogunyemi et al., 2020). The existence of these negative emotional responses creates a less conducive learning environment for academic achievement. Additionally, structural inequalities within STEM institutions contribute to disparities in resource access, limited mentorship opportunities, and support networks crucial for success in STEM fields (Atkins et al., 2020). …

Diosgenin Prevents Breast Cancer Metastasis Via The Inhibition Of Epithelial-Mesenchymal Transition., Santosh K. Singh, Rajesh Singh

Research Symposium

Background: Globally, breast cancer (BrCa) is the primary cause of cancer-related morbidity and death in women. Despite significant changes in healthcare activities like screening and early detection over the past few decades, African Americans (AA) continue to experience cancer health disparities. Many studies have been done on BrCa treatments, but AA patients have had less success than other racial or ethnic groups. Therefore, novel strategies are required to improve survival rates, lower BrCa mortality, and ultimately enhance the health of racial/ethnic minorities. Current treatment regimens, such as chemotherapeutic agents, are showing less effectiveness since they are linked to drug resistance, …

Development Of Solitary Keratoacanthoma From A Cutaneous Wart, Joshua M. Ninan, Veronica Salazar

Research Symposium

Background: Common cutaneous warts, referred to in medicine as verrucae vulgaris, are proliferative lesions caused by human papillomavirus. These lesions are mostly benign and usually resolve without incident, except in the case of the patient mentioned in this report. Our patient developed a solitary keratoacanthoma, currently accepted as a clinical variant of squamous cell carcinoma, as a result of several risk factors and traumatic exposure. The current literature does not have an established association of HPV with solitary keratoacanthomas. This case report explores the presentation and pathogenesis of solitary keratoacanthomas within the setting of HPV.

Implementing Meta-Session Autoregulation Strategies For Exercise- A Scoping Review, Adam Ibrahim, Cory T. Beaumont, Kelley Strohacker

International Journal of Exercise Science

International Journal of Exercise Science 17(5): 382-404, 2024. Meta-session autoregulation, a person-adaptive form of exercise prescription that adjusts training variables according to daily fluctuations in performance considering an individual’s daily fitness, fatigue, and readiness-to-exercise is commonly used in sports-related training and may be beneficial for non-athlete populations to promote exercise adherence. To guide refinement of meta-session autoregulation, it is crucial to examine the existing literature and synthesize how these procedures have been practically implemented. Following PRIMSA guidelines a scoping review of two databases was conducted from August 2021 to September 2021 to identify and summarize the selected measures of readiness-to-exercise …

Influence Of Body Composition On Functional Movement Among Police Officers, Stacy L. Gnacinski, Frankie Porter, Madison N. Renner, Tessa Laska

International Journal of Exercise Science

International Journal of Exercise Science 17(4): 418-428, 2024. Research indicates that the Functional Movement Screen (FMS) can be used to measure functional movement quality and characterize musculoskeletal injury risk in tactical populations. Although body composition has been linked to chronic disease in police officers, the link between body composition and functional movement quality has not been explored in this population. As such, the purposes of the study were to examine: (a) the effect of body mass index (BMI) on functional movement, and (b) determine the significance of fat mass (FM) and fat free mass (FFM) in predicting functional movement among …

Maximal Running Speed And Critical Speed Are Positively Related To Phase Angle In Healthy Young Adults, Trevor Short, Paulette Yamada

International Journal of Exercise Science

International Journal of Exercise Science 17(4): 405-417, 2024. Phase Angle (PhA), derived from bioelectrical impedance analysis, is a measurement of cellular resistance to electrical current and a non-invasive tool to monitor neuromuscular performance. The relationship between PhA and components of athletic performance is not fully understood. The purpose of this study was to determine if maximal running speed, critical speed (CS), and/or D prime (D’) derived from a 3-minute all-out-test (3MAOT) correlates to PhA, reactance (Xc), or resistance (R). Sixty-one (male n=35, female n=26) healthy young adults (23.4±3.9 years) completed bioelectrical impedance analysis (Inbody770) and a 3MAOT. The correlations between …

An Environmental History Of The Armed Occupation Act Of 1842: Empire, Cultivation, And Securing The Southernmost Frontier In The Contiguous United States, Gary Desantis

Florida Historical Quarterly

The Armed Occupation Act of 1842 (AOA) remains important to Florida's environmental history because it brought a stalwart band of white pioneers to take advantage of 200,000 acres of relatively untouched wilderness south of Gainesville. The basic tenants of the Act called for heads of households to bear arms against Seminoles, bestowed 160 acres of land to those who farmed at least five acres as well as constructed a domicile, and so succeeded in attracting new migrants that Florida achieved statehood three years later in 1845. The Act was effective in boosting the population-at least in giving Florida the 60,000 …

Organizing Knowledge Through Revealing Data In Knowledgebases., Jian Qin, Qiaoyi Liu

School of Information Studies - Faculty Scholarship

This paper uses the knowledgebases in the biomedical field as a case study to discuss the characteristics and requirements of knowledge organization (KO) practices and products by looking at the constructs, cross-linking, and curation methods. Modern knowledgebases such as Gene Ontology and Disease Ontology reflect the major expansions in KO to be more computational, portable (entification allows individual nodes to be extracted and used in combination with multiscale resources) and connected. Many techniques and methods used are not covered in KO textbooks. The interdisciplinary nature of KB development will be a worthwhile research area for the field of knowledge organization.

A Network Meta-Analysis Comparing Traditional Acupuncture Points And Ashi-Points: Dealyed Onset Muscle Soreness, Yufang Shao

Theses and Dissertations

Delayed onset muscle soreness (DOMS) is a type of muscle injury that can occur following moderate-to-high intensity physical activity. More recently, acupuncture has been considered as an alternative treatment method for muscle injury, which includes DOMS. However, there have been no specific investigations into potential differences when using traditional acupuncture (points based on traditional Chinese medicine theory), Ashi-acupuncture (points not on Chinese meridian, also known as tender points), or sham-acupuncture (superficial points, or points neither on the Chinese meridian nor the tender points) for treatment of DOMS. PURPOSE: To investigate the effectiveness of acupuncture treatment with traditional acupoints, Ashi points, …

The Infrared Absorption Spectrum Of Phenylacetylene And Its Deuterated Isotopologue In The Mid- To Far-Ir, Vincent J. Esposito, Pierro Ferrari, Wybren Jan Buma, Ryan C. Fortenberry, Christiaan Boersma, Alessandra Candian, Alexander G. G. M. Tielens

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Anharmonicity strongly influences the absorption and emission spectra of polycyclic aromatic hydrocarbon (PAH) molecules. Here, IR–UV ion-dip spectroscopy experiments together with detailed anharmonic computations reveal the presence of fundamental, overtone, as well as 2- and 3-quanta combination band transitions in the far- and mid-infrared absorption spectra of phenylacetylene and its singly deuterated isotopologue. Strong absorption features in the 400–900 cm⁻¹ range originate from CH(D) in-plane and out-of-plane wags and bends, as well as bending motions including the C≡C and CH bonds of the acetylene substituent and the aromatic ring. For phenylacetylene, every absorption feature is assigned either directly or …

“Drink The Kool-Aid, She Said ”: Female Villiany And Agency In Peoples Temple, Courtney Paige Smith

Theses and Dissertations

The responsibility for several hundred people drinking the Kool-Aid in Jonestown, Guyana, has typically been solely attributed to Jim Jones, the co-founder of the Peoples Temple movement. However, recent documentaries have shifted this representation to focus on all involved in the Peoples Temple. In this thesis, I use rhetorical analyses tactics through a critical feminist lens to examine the agency and villainy present in these mediated depictions of women in Peoples Temple. Mediated texts of the Peoples Temple included the 2018 Hulu documentary Jonestown: The Women Behind the Massacre, the 2018 AMC docuseries Jonestown: Terror in the Jungle, In Defense …

Decolonizing Anti-Racist Professional Development For Pk-12 Educators: Centering Indigenous Peoples Of The “Americas”, Claudia A. Fox Tree

Educational Studies Dissertations

This study explored challenges non-Indigenous educators face in centering Indigenous histories

and experiences in anti-racist professional development (PD) workshops for PK-12 educators. It addressed the process of transforming anti-racist PD and the significance of learning from Native American community members. The invisibility of Indigenous Peoples extends beyond physical aspects tied to attempted genocide and includes the invisibility of the political rights of tribal citizens. It encompasses exclusion from historical conversations, anti-racism research, and statistical data. In contrast, the hypervisibility of stereotypical images and inaccurate information starkly contrasts the invisibility of authentic images and accurate resources. The Indigenous methodology of two-eye …
