Association Of Functional Movement Screen And Y-Balance Test Scores With Injury In Elite Fast-Pitch Softball Athletes, Xiujing Zhao

Student Theses and Dissertations

The purpose of this study was to evaluate the association of FMS and YBT composite scores with injury in elite female fast-pitch softball athletes. Thirty-eight participants completed pre-season FMS and YBT assessments. Injury data were collected on the next day of finishing the season. FMS composite scores were significantly lower for the injured group (13.5 ± 2.4) comparison to the non-injured group 16.9 ± 1.6) (p ≤ .001, d = 1.67). Injured status was associated with lower FMS scores (r = .61; p <.001). No differences existed in YBT-UQ (p =.67, d = .14) and YBT-LQ (p =.16, d =.50) composite score between the injured (UQ = 96.0 ± 5.9, LQ = 96.7 ± 8.2) and the non-injure (UQ = 97.1 ± 1.6, LQ = 101.0 ± 9.1) groups; no significant associations were found between injury status and YBT-UQ composite scores (r = -.08; p = .64) or YBT-LQ composite scores (r = -.24; p = .14). Preseason FMS composite score was associated with subsequent injury.

Poststroke Seizure And Epilepsy: A Review Of Incidence, Risk Factors, Diagnosis, Pathophysiology, And Pharmacological Therapies, Joseph Phan, Mario Ramos, Theodore Soares, Mayur S. Parmar

HPD Articles

Stroke is the most common cause of epilepsy and ultimately leads to a decrease in the quality of life of those affected. Ischemic and hemorrhagic strokes can both lead to poststroke epilepsy (PSE). Significant risk factors for PSE include age less than 65 years, stroke severity measured by the National Institutes of Health Stroke Scale (NIHSS), cortical involvement, and genetic factors such as TRPM6 polymorphism. The diagnosis of PSE is made by using imaging modalities, blood biomarkers, and prognostic criteria. Electroencephalography (EEG) is currently the gold standard to diagnose PSE, while new combinations of modalities are being tested to increase …

With an incidence of ~1 in 800 births, Down syndrome (DS) is the most com- mon chromosomal condition linked to intellectual disability worldwide. While the genetic basis of DS has been identified as a triplication of chromosome 21 (HSA21), the genes encoded from HSA 21 that directly contribute to cognitive de fi cits remain incompletely understood. Here, we found that the HSA21- encoded chromatin effector, BRWD1, was upregulated in neurons derived from iPS cells from an individual with Down syndrome and brain of trisomic mice. We showed that selective copy number restoration of Brwd1 in trisomic animals rescued de fi …

Cftr Deletion In Mouse Epithelial And Immune Cells Differentially Influence The Intestinal Microbiota, Callie E. Scull, Meng Luo, Scott Jennings, Christopher M. Taylor, Guoshun Wang

School of Medicine Faculty Publications

Cystic fibrosis (CF) is a life-threatening genetic disorder, caused by mutations in the CF transmembrane-conductance regulator gene (cftr) that encodes CFTR, a cAMP-activated chloride and bicarbonate channel. Clinically, CF lung disease dominates the adult patient population. However, its gastrointestinal illness claims the early morbidity and mortality, manifesting as intestinal dysbiosis, inflammation and obstruction. As CF is widely accepted as a disease of epithelial dysfunction, it is unknown whether CFTR loss-of-function in immune cells contributes to these clinical outcomes. Using cftr genetic knockout and bone marrow transplantation mouse models, we performed 16S rRNA gene sequencing of the intestinal microbes. Here we …

Evaluation Of Breastfeeding App Features: Content Analysis Study, Lauren Dinour, Antoinette Pole

Department of Nutrition and Food Studies Scholarship and Creative Works

Background: While a variety of health apps abound, less than half of adults in the United States report using a health app, despite the ubiquity of smartphones among users aged 18 to 49 years. Several studies have examined the use of breastfeeding apps; however, less is known about the types of features found on these apps and what factors might influence app ratings.

Objective: This paper seeks to characterize breastfeeding apps, assess whether apps with higher user ratings differ from apps with lower user ratings in their tracking and nontracking features, and analyze whether the type and number of features …

Faculty Publications

Background

Excessive gestational weight gain has increased over time and is resistant to intervention, especially in women living with overweight or obesity. This study described the process evaluation methods and findings from a behavioral lifestyle intervention for African American and white women living with overweight and obesity that spanned pregnancy (≤ 16 weeks gestation) through 6 months postpartum.

Methods

The Health in Pregnancy and Postpartum (HIPP) study tested a theory-based behavioral intervention (vs. standard care) to help women (N = 219; 44% African American, 29.1 ± 4.8 years) living with overweight or obesity meet weight gain guidelines in pregnancy and …

Historical Corn Price Evolution Implications For Pre-Harvest Hedging, Cory Walters, Richard K. Preston

Cornhusker Economics

Commodity markets evolve through information provided by participating buyers and sellers and throughout this process the conditions in which commodity markets work are revealed. Producer pre-harvest commodity marketing can be further developed by incorporating information on how commodity markets work, leading to better farm financial performance.

We investigate how commodity markets have historically evolved from spring to fall. While changes in future prices appear random in any given year, observing average daily prices over 32 years could uncover a seasonal tendency. In the past 32 years, the average daily price tends to be higher in the spring than the fall, …

Dysfunctional Glymphatic System With Disrupted Aquaporin 4 Expression Pattern On Astrocytes Causes Bacterial Product Accumulation In The Csf During Pneumococcal Meningitis, Jaqueline S Generoso, Sigrun Thorsdottir, Allan Collodel, Diogo Dominguini, Roberta R E Santo, Tatiana Barichello

Faculty, Staff and Student Publications

Pneumococcal meningitis, inflammation of the meninges due to an infection of the Central Nervous System caused by Streptococcus pneumoniae (the pneumococcus), is the most common form of community-acquired bacterial meningitis globally. Aquaporin 4 (AQP4) water channels on astrocytic end feet regulate the solute transport of the glymphatic system, facilitating the exchange of compounds between the brain parenchyma and the cerebrospinal fluid (CSF), which is important for the clearance of waste away from the brain. Wistar rats, subjected to either pneumococcal meningitis or artificial CSF (sham control), received Evans blue-albumin (EBA) intracisternally. Overall, the meningitis group presented a significant impairment of …

Systematic Analysis Of Mobile Genetic Elements Mediating Β-Lactamase Gene Amplification In Noncarbapenemase-Producing Carbapenem-Resistant Enterobacterales Bloodstream Infections, W C Shropshire, A Konovalova, P Mcdaneld, M Gohel, B Strope, C N Tran, J Kim, X Zhan, S Aitken, M Bhatti, T C Savidge, T J Treangen, B M Hanson, C A Arias, S A Shelburne

Faculty, Staff and Student Publications

Noncarbapenemase-producing carbapenem-resistant Enterobacterales (non-CP-CRE) are increasingly recognized as important contributors to prevalent carbapenem-resistant Enterobacterales (CRE) infections. However, there is limited understanding of mechanisms underlying non-CP-CRE causing invasive disease. Long- and short-read whole-genome sequencing was used to elucidate carbapenem nonsusceptibility determinants in Enterobacterales bloodstream isolates at MD Anderson Cancer Center in Houston, Texas. We investigated carbapenem nonsusceptible Enterobacterales (CNSE) mechanisms (i.e., isolates with carbapenem intermediate resistance phenotypes or greater) through a combination of phylogenetic analysis, antimicrobial resistance gene detection/copy number quantification, porin assessment, and mobile genetic element (MGE) characterization. Most CNSE isolates sequenced were non-CP-CRE (41/79; 51.9%), whereas 25.3% (20/79) were …

Viruses In Astrobiology, Ignacio De La Higuera, Ester Lázaro

Biology Faculty Publications and Presentations

Viruses are the most abundant biological entities on Earth, and yet, they have not received enough consideration in astrobiology. Viruses are also extraordinarily diverse, which is evident in the types of relationships they establish with their host, their strategies to store and replicate their genetic information and the enormous diversity of genes they contain. A viral population, especially if it corresponds to a virus with an RNA genome, can contain an array of sequence variants that greatly exceeds what is present in most cell populations. The fact that viruses always need cellular resources to multiply means that they establish very …

Contrasting Particle Fluxes And Composition In A Submarine Canyon Affected By Natural Sediment Transport Events And Bottom Trawling, Sarah Paradis, Marta Arjona-Camas, Miguel Goñi, Albert Palanques, Pere Masqué, Pere Puig

Research outputs 2022 to 2026

Submarine canyons are important conduits of sediment and organic matter to deep-sea environments, mainly during high-energy natural events such as storms, river floods, or dense shelf water cascading, but also due to human activities such as bottom trawling. The contributions of natural and trawling-induced sediment and organic matter inputs into Palamós Canyon (NW Mediterranean) were assessed from three instrumented moorings deployed in the axis and northern flank of the canyon covering the trawling closure (February) and the trawling season (March-December) of 2017. During the trawling closure, large sediment fluxes with high contents of labile marine organic matter content were registered …

Using The Embl-Ebi Clustal Omega Tool To Calculate Diversity Of Heavy Chain Phage-Display Libraries, Michael Bodri, Shane A. Webb

Georgia Journal of Science

Here we show that traditional Sanger sequencing combined with analysis tools available from the European Molecular Biology Laboratory-European Bioinformatics Institute (EMBL-EBI), specifically EMBOSS Transeq and Clustal Omega, is extremely effective in the analysis of naïve phage display antibody libraries for the determination of library size and diversity. The free tools are easy to use and require little manipulation of reads by hand, allowing analysis to be performed on a standard personal computer. Utilization of this technique has applicability to researchers with limited access to deep sequencing. The primary drawback to this analysis methodology is that antibodies with particular molecular or …

This Is Sparta!: Attitudes Of Ncaa Division I Compliance Officers Towards Athlete Agent Regulations, Mark Thomas Gurenlian

Student Theses and Dissertations

The topic covered in this Thesis is that of the Sports Agent Responsibility and Trust Act (SPARTA), the state adopted Uniform Athlete Agents Act, and any other laws that are used to control athlete agents. Specifically, how these laws fail to properly protect collegiate student-athletes and fail to regulate athlete agents. There is a review of previous articles and research that promote the idea that SPARTA was not fully comprehensive and that the UAAA laws are missing key details. The study consists of a questionnaire sent to Division I compliance officers and their responses supported the notion that not only …

Enhancing Production Of Functional Proteins In Plant Cell Culture Through Cellular Engineering And Rational Protein Design, Uddhab Karki

Student Theses and Dissertations

Plant cell culture is emerging as a promising alternative bioproduction platform for valuable proteins due to its low cost of production, safety (free from animal pathogen contamination) and ease of scale-up. However, there are common challenges for commercialization, including low protein yields, difficulty in cryopreservation, and non-human glycosylation, etc. This research project addresses the overarching research hypothesis that strategically modifying the plant cell genome using CRISPR/Cas9 technology and rationally designing protein molecules by fusing with a functional module enhance the production of protein in plant cell culture and improve protein function. There are two specific aims addressed in this project: …

Articles

This work aims at developing biodegradable active chitosan-alginate layer-by-layer bio-nanocomposite film with TiO₂NPs using the solvent casting method followed by CaCl₂ crosslinking for food packaging applications. The developed films enhanced the tensile strength and elongation at break by 14.76 and 2 folds (p < 0.05) respectively. The UV barrier properties of CH-SA-0.3%TiO₂ film increased by 88.6%, while the film transparency decreased by 87.23%. All films showed antimicrobial activity against foodborne pathogens E. coli, S. aureus, S. typhi, and L. monocytogene. The film with 0.1%TiO₂ showed the complete killing of gram-positive bacteria. The CH-SA-0.1%TiO₂ film was completely biodegraded during the …

Evaluation Of Allogeneic And Autologous Membrane-Bound Il-21-Expanded Nk Cells For Chronic Lymphocytic Leukemia Therapy, Max Yano, Chia Sharpe, J Rachel Lance, Janani Ravikrishnan, Kevan Zapolnik, Jennifer A Woyach, Adam S Kittai, Sumithira Vasu, Seema Bhat, Kerry A Rogers, Dean A Lee, Natarajan Muthusamy, John C Byrd

Faculty, Staff and Student Publications

Successes with anti-CD20 antibodies in chronic lymphocytic leukemia (CLL) and enhanced activity of Fc-engineered vs unmodified antibody therapy suggest a potentially impactful role for natural killer (NK) cells and other innate immune cells in controlling this disease. Stimulated NK cells have shown promise as a cellular therapy, but their application has been constrained by limited expansion capacity and low cytotoxic activity against CLL cells. Here, we demonstrate that both healthy donor-derived and CLL patient-derived NK cells expand rapidly when stimulated with feeder cells expressing membrane-bound interleukin-21 (mbIL-21) and have potent cytotoxic activity against allogeneic or autologous CLL cells. Combination with …

Ubr2 Targets Myosin Heavy Chain Iib And Iix For Degradation: Molecular Mechanism Essential For Cancer-Induced Muscle Wasting, Song Gao, Guohua Zhang, Zicheng Zhang, James Z Zhu, Li Li, George G Rodney, Lindsey Anderson, Jose M Garcia, Yong Tae Kwon, Yi-Ping Li

Faculty, Staff and Student Publications

Cancer cachexia is a lethal metabolic syndrome featuring muscle wasting with preferential loss of fast-twitching muscle mass through an undefined mechanism. Here, we show that cancer induces muscle wasting by selectively degrading myosin heavy chain (MHC) subtypes IIb and IIx through E3 ligase UBR2-mediated ubiquitylation. Induction of MHC loss and atrophy in C2C12 myotubes and mouse tibialis anterior (TA) by murine cancer cells required UBR2 up-regulation by cancer. Genetic gain or loss of UBR2 function inversely altered MHC level and muscle mass in TA of tumor-free mice. UBR2 selectively interacted with and ubiquitylated MHC-IIb and MHC-IIx through its substrate recognition …

Summit: An Integrative Approach For Better Transcriptomic Data Imputation Improves Causal Gene Identification, Zichen Zhang, Ye Eun Bae, Jonathan R Bradley, Lang Wu, Chong Wu

Faculty, Staff and Student Publications

Genes with moderate to low expression heritability may explain a large proportion of complex trait etiology, but such genes cannot be sufficiently captured in conventional transcriptome-wide association studies (TWASs), partly due to the relatively small available reference datasets for developing expression genetic prediction models to capture the moderate to low genetically regulated components of gene expression. Here, we introduce a method, the Summary-level Unified Method for Modeling Integrated Transcriptome (SUMMIT), to improve the expression prediction model accuracy and the power of TWAS by using a large expression quantitative trait loci (eQTL) summary-level dataset. We apply SUMMIT to the eQTL summary-level …

Biomarkers Beyond Brca: Promising Combinatorial Treatment Strategies In Overcoming Resistance To Parp Inhibitors, Yu-Yi Chu, Clinton Yam, Hirohito Yamaguchi, Mien-Chie Hung

Faculty, Staff and Student Publications

Poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi) exploit the concept of synthetic lethality and offer great promise in the treatment of tumors with deficiencies in homologous recombination (HR) repair. PARPi exert antitumor activity by blocking Poly(ADP-ribosyl)ation (PARylation) and trapping PARP1 on damaged DNA. To date, the U.S. Food and Drug Administration (FDA) has approved four PARPi for the treatment of several cancer types including ovarian, breast, pancreatic and prostate cancer. Although patients with HR-deficient tumors benefit from PARPi, majority of tumors ultimately develop acquired resistance to PARPi. Furthermore, even though BRCA1/2 mutations are commonly used as markers of PARPi sensitivity in …

Mindfulness In University Students: A Tool For Managing Stress, Lyndsey Kunzler

Family Perspectives

Mindfulness can be a meaningful practice across different stages of life: it can help improve well-being for young children (Becker & Whitaker, 2018; Esmaeilian et al., 2018; Li et al., 2019), adolescents (Leavitt et al., 2020; Oppo et al., 2019), and adults (Berk et al., 2018; Pierson et al., 2019). Mindfulness is the act of clearing the mind, being present, and paying attention with the intent to improve well-being (Greeson et al., 2014). Mindfulness began as a common Buddhist practice, but in the 1970s Jon Kabat-Zinn created mindfulness-based stress reduction (MBSR) in an attempt to aid mental health issues (Greeson …

Effects Of Parents’ Avoidant And Anxious Attachment On Children, Nicole Busacker

Family Perspectives

Avoidant and anxious attachment styles are both negative ways of dealing with the need for connection or bonding. One reason these attachment styles develop is in “the absence of a secure bond with an available and responsive ‘other,’ rigid, repetitive internal and interpersonal coping patterns or attachment strategies develop” (Brubacher, 2017, p. 52–53). These coping patterns are made manifest in either avoidant or anxious attachment behaviors and are mainly expressed in relation to spouses and children.

Subtype C Hiv-1 Reservoirs Throughout The Body In Art-Suppressed Individuals, Zhou Liu, Peter Julius, Guobin Kang, John T. West, Charles Wood

School of Biological Sciences: Faculty Publications

Subtype B HIV-1 reservoirs have been intensively investigated, but reservoirs in other subtypes and how they respond to antiretroviral therapy (ART) is substantially less established. To characterize subtype C HIV-1 reservoirs, we implemented postmortem frozen, as well as formalin fixed paraffin embedded (FFPE) tissue sampling of central nervous system (CNS) and peripheral tissues. HIV-1 LTR, gag, envelope (env) DNA and RNA was quantified using genomic DNA and RNA extracted from frozen tissues. RNAscope was used to localize subtype C HIV-1 DNA and RNA in FFPE tissue. Despite uniform viral load suppression in our cohort, PCR results …

Association Between Use Of Remdesivir And Bradycardia, Gibret Umeukeje

USF Tampa Graduate Theses and Dissertations

Remdesivir received the first emergency use authorization from the FDA for the treatment of COVID-19. Multiple adverse drug reactions (ADR) have been reported since its approval in October 2020. Bradycardia, defined by a decrease in heart rate has been reported as an adverse event for patients receiving remdesivir for COVID-19 treatment. The purpose of the research is to systematically investigate the frequency of occurrence of bradycardia in adults receiving remdesivir using clinical data derived from the FDA Adverse Event Reporting System (FAERS) database. Patients receiving remdesivir were compared to those receiving Paxlovid, Regen-Cov, and Dexamethasone for COVID-19 treatment to see …

Correlation Of Phosphorus Adsorption With Chemical Properties Of Aluminum-Based Drinking Water Treatment Residuals Collected From Various Parts Of The United States, Roxana Rahmati, Virinder Sidhu, Rosita Nunez, Rupali Datta, Dibyendu Sarkar

Michigan Tech Publications, Part 1

Over the past several decades, the value of drinking water treatment residuals (WTRs), a byproduct of the coagulation process during water purification, has been recognized in various environmental applications, including sustainable remediation of phosphorus (P)-enriched soils. Aluminum-based WTRs (Al-WTRs) are suitable adsorbent materials for P, which can be obtained and processed inexpensively. However, given their heterogeneous nature, it is essential to identify an easily analyzable chemical property that can predict the capability of Al-WTRs to bind P before soil amendment. To address this issue, thirteen Al-WTRs were collected from various geographical locations around the United States. The non-hazardous nature of …

The Impact Of Covid-19 On Opioid-Related Overdose Deaths In Texas, Bhanumathi Gopal, Tiffany Champagne-Langabeer

Faculty, Staff and Student Publications

Prior to the COVID-19 pandemic, the United States was facing an epidemic of opioid overdose deaths, clouding accurate inferences about the impact of the pandemic at the population level. We sought to determine the existence of increases in the trends of opioid-related overdose (ORO) deaths in the Greater Houston metropolitan area from January 2015 through December 2021, and to describe the social vulnerability present in the geographic location of these deaths. We merged records from the county medical examiner's office with social vulnerability indexes (SVIs) for the region and present geospatial locations of the aggregated ORO deaths. Time series analyses …
