Steeper Size Spectra With Decreasing Phytoplankton Biomass Indicate Strong Trophic Amplification And Future Fish Declines, Angus Atkinson, Axel G. Rossberg, Ursula Gaedke, Gary Sprules, Ryan F. Heneghan, Stratos Batziakas, Maria Grigoratou, Elaine Fileman, Katrin Schmidt, Constantin Frangoulis

School of Geography, Earth and Environmental Sciences

Under climate change, model ensembles suggest that declines in phytoplankton biomass amplify into greater reductions at higher trophic levels, with serious implications for fisheries and carbon storage. However, the extent and mechanisms of this trophic amplification vary greatly among models, and validation is problematic. In situ size spectra offer a novel alternative, comparing biomass of small and larger organisms to quantify the net efficiency of energy transfer through natural food webs that are already challenged with multiple climate change stressors. Our global compilation of pelagic size spectrum slopes supports trophic amplification empirically, independently from model simulations. Thus, even a modest …

Development Of A Suspended Aerobic Membrane Bioreactor (Sambr) For Sustainable Wastewater Treatment On Early Planetary Bases, Talon James Bullard

USF Tampa Graduate Theses and Dissertations

Environmental Control and Life Support Systems (ECLSS) ideally should treat all “waste” streams for recovery in a sustainable and near closed-loop manner. This will be critical for Partial Gravity Habitats (PGH) and Early Planetary Bases (EPB) that will be established on the Moon and Mars due to the lack of readily available resources. Currently, the Water Recovery System (WRS), onboard the International Space Station (ISS), recovers and purifies water from urine and graywater. While efficient, this system is not optimized for future missions and utilizes physical-chemical technologies that operate with single-use and hazardous consumables. In response to the lack of …

Cell Membrane-Anchored And Tumor-Targeted Il-12 T-Cell Therapy Destroys Cancer-Associated Fibroblasts And Disrupts Extracellular Matrix In Heterogenous Osteosarcoma Xenograft Models, Jiemiao Hu, Alexander J Lazar, Davis Ingram, Wei-Lien Wang, Wendong Zhang, Dristhi Ragoonanan, Xueqing Xia, Kris Mahadeo, Richard Gorlick, Shulin Li

Faculty, Staff and Student Publications

Background: The extracellular matrix (ECM) and cancer-associated fibroblasts (CAFs) play major roles in tumor progression, metastasis, and the poor response of many solid tumors to immunotherapy. CAF-targeted chimeric antigen receptor-T cell therapy cannot infiltrate ECM-rich tumors such as osteosarcoma.

Method: In this study, we used RNA sequencing to assess whether the recently invented membrane-anchored and tumor-targeted IL-12-armed (attIL12) T cells, which bind cell-surface vimentin (CSV) on tumor cells, could destroy CAFs to disrupt the ECM. We established an in vitro model of the interaction between osteosarcoma CAFs and attIL12-T cells to uncover the underlying mechanism by which attIL12-T cells penetrate …

Age-Related Differences In Motor Skill Transfer With Brief Memory Reactivation, Kylie B Tomlin, Brian P Johnson, Kelly P Westlake

2020-Current year OA Pubs

Motor memories can be strengthened through online practice and offline consolidation. Offline consolidation involves the stabilization of memory traces in post-practice periods. Following initial consolidation of a motor memory, subsequent practice of the motor skill can lead to reactivation and reconsolidation of the memory trace. The length of motor memory reactivation may influence motor learning outcomes; for example, brief, as opposed to long, practice of a previously learned motor skill appears to optimize intermanual transfer in healthy young adults. However, the influence of aging on reactivation-based motor learning has been scarcely explored. Here, the effects of brief and long motor …

The Immune System And Metabolic Products In Epilepsy And Glioma-Associated Epilepsy: Emerging Therapeutic Directions, Craig M Horbinski, Jessica W Templer, Joshua M Rosenow, Timothy L Sita, Charles D James, Benjamin Deneen, Stephen D Miller, Amy B Heimberger

Faculty, Staff and Students Publications

Epilepsy has a profound impact on quality of life. Despite the development of new antiseizure medications (ASMs), approximately one-third of affected patients have drug-refractory epilepsy and are nonresponsive to medical treatment. Nearly all currently approved ASMs target neuronal activity through ion channel modulation. Recent human and animal model studies have implicated new immunotherapeutic and metabolomic approaches that may benefit patients with epilepsy. In this Review, we detail the proinflammatory immune landscape of epilepsy and contrast this with the immunosuppressive microenvironment in patients with glioma-related epilepsy. In the tumor setting, excessive neuronal activity facilitates immunosuppression, thereby contributing to subsequent glioma progression. …

Indirect Effects Of Self-Compassion On Self-Forgiveness Through Self-Esteem And Self-Condemnation With Gender Moderation: A Parallel Moderated Mediation Analysis, Jill A. Marin

Doctoral Dissertations and Projects

Two studies explored the relationship between self-compassion and self-forgiveness as well as the role of self-esteem, self-condemnation, and gender in that relationship. Since self-forgiveness is associated with greater well-being, the studies’ importance included gaining knowledge to increase well-being by investigating factors that contribute to self-forgiveness. Research questions were if the relationship between self-compassion and self-forgiveness was mediated by self-esteem and self-condemnation and if gender moderated those mediations. Two quantitative correlational studies, of 94 MTurk and 114 social media participants, used online Qualtrics surveys with established measurements to collect data. Associations, mediators, and moderators were examined by bivariate correlations, mediation analysis, …

Moral Disengagement And Psychopathy: A Quantitative Correlational Study On Attachment To God And Empathy, Kimberly Essler

Doctoral Dissertations and Projects

Moral disengagement and lack of empathy are rising concerns in the United States. Those who are morally disengaged or display limited empathy are often associated with anti-social personality disorder or psychopathy. Studies consistently show trauma and early childhood attachment are predictors for the development of behaviors associated with psychopathy. Current literature has demonstrated semi-effective therapeutic treatment and pharmacotherapy for comorbid disorders and symptoms such as anxiety. However, research fails to adequately address the prevention and treatment of lack of empathy – a major factor in the perilous behaviors of psychopathy. Psychopathy includes structural and functional brain abnormalities in the cortical …

Indirect Prophecies Concerning The Death Of Christ In Narrative, Lindsay A. Siemers

Doctoral Dissertations and Projects

In Luke 24, two disciples recognized that Jesus had predicted He would suffer, be betrayed, and handed over to death by crucifixion, and had said He would rise again on the third day.
