Influence Of Acute High-Intensity Resistance Exercise On Cognitive Performance And Prefrontal Cortex Oxygenation In Recreational Weightlifters, Samuel M. Camacho, Terence Moriarty, Mick G. Mack, Jacob P. Reed, Hyeyoung Cho

Topics in Exercise Science and Kinesiology

Acute exercise has been shown to be effective in improving post-exercise cognitive performance, including executive function. In addition, changes in prefrontal cortex (PFC) activation have been linked to any such improvements. Since resistance and higher intensity exercise is much less studied, the aim of this study was to examine the effect of high-intensity resistance exercise on cognitive performance and to determine if PFC activation was related to this cognitive performance in recreationally trained weightlifters. Ten (M = 5, F = 5) college aged (22 ± 2 years) recreationally trained weightlifters completed the Stroop task prior to and 15- and 30-min …

Soybean is a major legume crop cultivated globally due to the high quality and quantity of its seed protein and oil. However, drought stress is the most significant factor that decreases soybean yield, and more than 90% of US soybean acreage is dependent on rainfall. Water use efficiency (WUE) is positively correlated with the carbon isotopic ratio 13C/12C (C13 ratio) and selecting soybean varieties for high C13 ratio may enhance WUE and help improve tolerance to drought. Our study objective was to identify genetic loci associated with C13 ratio using a diverse set of 205 soybean maturity …

School of Dentistry Faculty Publications

Introduction: The sufCDSUB gene cluster, encoding the sole iron-sulfur (Fe-S) cluster assembly system in S. mutans, was recently shown to be up-regulated in response to oxidative stressors and Fe limitation. Methods: In this study, luciferase reporter fusion assays, electrophoretic gel mobility shift assays (EMSA) and in vitro transcription assays (IVT) were used to dissect the cis- and trans-acting factors that regulate the expression of sufCDSUB. Results and discussion: Results showed deletion of perR, for the only Fur-family transcriptional regulator in S. mutans, resulted in > 5-fold increases in luciferase activity under the control of the sufCDSUB promoter (P < 0.01), as compared to the parent strain, UA159 when the reporter strains were grown in medium with no supplemental iron. Site-directed mutagenesis of a PerR-box in the promoter region led to elevation of the reporter activity by >1.6-fold (P < 0.01). In an EMSA, recombinant PerR (rPerR) was shown to bind to the cognate sufCDSUB promoter leading to mobility retardation. On the other hand, the reporter activity was increased by > 84-fold …

Understanding Mechanisms For Coastal Marsh Sustainability In A Changing Climate, Ashley R. Booth Nov 2024

Understanding Mechanisms For Coastal Marsh Sustainability In A Changing Climate, Ashley R. Booth

LSU Doctoral Dissertations

In the Chenier Plain of Louisiana and Texas, coastal marshes are subject to high rates of relative sea level rise (RSLR), restricted sedimentation, and declining elevation attributed to subsidence and decades of intensive management. These marshes were created via mineral sedimentation but now largely accrete via organic matter accumulation. This organic matter accumulation (OMA) – or the balance between plant productivity and decomposition – is essential for maintaining elevation and thus long-term sustainability. However, management for elevation is complicated by a poor understanding of how abiotic factors like flooding and salinity impact processes driving OMA and elevation. To better understand …

The goal of therapeutic cancer vaccines and immune checkpoint therapy (ICT) is to promote T cells with anti-tumor capabilities. Here, we compared mutant neoantigen (neoAg) peptide-based vaccines with ICT in preclinical models. NeoAg vaccines induce the most robust expansion of proliferating and stem-like PD-1+TCF-1+ neoAg-specific CD8 T cells in tumors. Anti-CTLA-4 and/or anti-PD-1 ICT promotes intratumoral TCF-1- neoAg-specific CD8 T cells, although their phenotype depends in part on the specific ICT used. Anti-CTLA-4 also prompts substantial changes to CD4 T cells, including induction of ICOS+Bhlhe40+ T helper 1 (Th1)-like cells. Although neoAg vaccines or ICTs expand iNOS+ macrophages, neoAg vaccines …

The Regulation Of The Secreted Proteases In Usa300 Isolates Of Staphylococcus Aureus, Jessica K. Jackson

USF Tampa Graduate Theses and Dissertations

Staphylococcus aureus is a Gram-positive opportunistic pathogen capable of causing myriad diseases, ranging from skin infections to pneumonia, endocarditis, and sepsis. It does this via the production of an array of virulence factors including toxins, adhesins, immunoglobulin-binding proteins, and proteases. Towards these latter elements, S. aureus produces ten secreted proteases that play a dual role in infection: firstly, by modulating the stability and abundance of other virulence factors, and secondly, by cleaving host factors to facilitate infection. Given their importance, we set out to explore the natural variability of protease production in a collection of clinical isolates from Tampa General …

Species Distribution Modeling With Environmental Time Series Data And Deep Learning, Austin M. Smith Nov 2024

Species Distribution Modeling With Environmental Time Series Data And Deep Learning, Austin M. Smith

USF Tampa Graduate Theses and Dissertations

Species distribution models (SDM) are frequently used to gain ecological understanding and guide conservation decisions. These models are developed with a wide variety of procedures - from regression-based approaches to more modern machine learning algorithms - but a requirement almost all share is the use of predictor variables that strongly simplify the temporal variability of driving factors. These static features are chosen by the user, which can incorporate unnecessary bias into a study. Additionally, current data preparation techniques often remove variables from the process entirely, which inherently removes information that may still be of importance. Conversely, novel architectures of deep …

Cd46 Is A Protein Receptor For Human Adenovirus Type 64, Eugene Y. Wu, Alexander M. Robertson, Hanglin (Henry) Zhu, Corina Stasiak, Laura A. Murray-Nerger, Emily Romanoff, Jesse Woon, Beth A. Bromme, Jason G. Smith

Biology Faculty Publications

Certain species D human adenoviruses (HAdV-D19, -D37, and -D64) are causative agents of epidemic keratoconjunctivitis. HAdV-D37 has previously been shown to bind CD46 (membrane cofactor protein) and sialic acid as adhesion receptors. HAdV-D64 is genetically highly similar to HAdV-D37, with an identical fiber protein sequence, but differs substantially in its penton base and hexon proteins, two other major capsid components, due to genetic recombination. Here, we demonstrate that, like HAdV-D37, HAdV-D64 virions bind directly to CD46 and that CD46 and sialic acid also function as receptors for HAdV-D64 on multiple cell types. Expression of CD46 on CD46-negative cells conferred susceptibility …
