However, at the time this study was initiated and completed, the TEEN screen was utilized. After the screening is performed, regardless of type, it is up to the provider to address these findings in a safe and effective manner. The goal …


Introducing Patient-Centered Outcomes To Preceptors In Caate-Approved Athletic Training Programs, K. Judge 2025 Idaho State University

Introducing Patient-Centered Outcomes To Preceptors In Caate-Approved Athletic Training Programs, K. Judge

Clinical Practice in Athletic Training

The 2020 standards set by the Commission on Accreditation of Athletic Training Education (CAATE) now require the incorporation of the International Classification of Function and Patient-Centered Outcomes into professional practice. These standards can be introduced initially through simulation, but to develop a competent and culturally aware professional, outcome measures should be completed during clinical experiences under the guidance of approved preceptors. As this is a relatively new standard, many preceptors did not receive this as part of their education and may be uncomfortable integrating outcomes into their practice. This lack of integration can negatively affect the learning opportunities of athletic …

Several days after the patient was cleared, she reported her ankle feeling “stuck.” Upon evaluation, …


Structural Variation Of The Right Coronary Ostium And Its Implications To Cardiac Medicine, Jessica L. Hensley, Joseph X. Anders, Timothy Robinson, William Srinivasan, Donald G. Matz, Ethan L. Snow 2025 South Dakota State University

Structural Variation Of The Right Coronary Ostium And Its Implications To Cardiac Medicine, Jessica L. Hensley, Joseph X. Anders, Timothy Robinson, William Srinivasan, Donald G. Matz, Ethan L. Snow

The Journal of Integrative Physiology

Introduction: The high oxygen demand of the heart’s myocardium is met via perfusion through the coronary arterial system. During embryological development, the right (RCA) and left (LMCA) coronary arteries fuse onto the aortic root, creating right (RCO) and left (LCO) ostial openings respectively to join the closed circulatory system. Regardless of their widely variable branching patterns, the ability of the RCA and LMCA to perfuse the myocardium initially relies on the functional patency of the coronary ostia. The objective of this study is to examine a unique extra-ostial tissue structure found overlying an RCO and provide a literature-based discussion of …


Untangling The Roles Of Pulmonary Vagal Afferent Subsets With Inhaled Irritants, Teresa Darcey 2025 University of South Florida

Untangling The Roles Of Pulmonary Vagal Afferent Subsets With Inhaled Irritants, Teresa Darcey

USF Tampa Graduate Theses and Dissertations

The sensory nerves in the airways directly regulate critical defenses and indirectly regulate vital gas exchange. Airway function is largely controlled by the autonomic nervous system, and our understanding of its sensory regulation is directly connected to our ability to treat respiratory and cardiovascular pathologies. Airway sensory afferents are heterogeneous with respect to their electrophysiological properties, peptidergic capacity, and stimuli sensitivity, which at least in part dictate some of their various functions. There is evidence that embryological origin impacts reflex function: activation of the neural crest-derived population of sensory afferents has been shown to evoke the cough reflex whereas activation …

Altered cell surface glycosylation is a hallmark of cancer; among aberrant glycan structures, hypersialylated proteins contribute to disease progression. The enzyme ST6 β-galactoside α2,6-sialyltransferase 1 (ST6GAL1) mediates α2,6-linked sialylation of N-glycosylated proteins and is upregulated in many cancers, including prostate cancer (PrCa). We propose that ST6GAL1 may be released by cancer cells in small extracellular vesicles (sEVs) in the PrCa tumor microenvironment to potentially modulate cell surface sialylation in recipient cells. We isolated sEVs from PrCa cells by density gradient separation and characterized them by nanoparticle tracking analysis using ZetaView and immunoblotting analysis. We identified ST6GAL1 in both its membrane-bound …

Stayin' Alive (Even Without Oxygen): Retinal Development In Austrofundulus Limnaeus, Carmen Zecilia Rodriguez

Dissertations and Theses

The vertebrate eye is one of the most metabolically active organs in the body and is particularly sensitive to environmental stressors such as oxygen deprivation. Understanding how eye development proceeds under such conditions can provide critical insights into mechanisms of cellular resilience, tissue organization, and developmental plasticity. The annual killifish Austrofundulus limnaeus represents a unique model for investigating these processes due to its remarkable tolerance to anoxia during embryogenesis. However, the wild-type form is heavily pigmented, limiting the effectiveness of traditional imaging techniques for studying eye development. This thesis characterizes eye development and anoxia resilience in both wild-type and melanin-deficient …

International Journal of Exercise Science

International Journal of Exercise Science 18(7): 971-983, 2025. The total work completed during an exercise session is often assumed to be the primary factor influencing the kinetics of post-exercise recovery. However, the duration of work and rest periods during high intensity interval training (HIIT) have been shown to impact the magnitude of physiological stress and could also impact post-exercise recovery. The aim of this study was to characterize the recovery time course of neuromuscular function following work-to-rest matched HIIT protocols with different work interval durations and conducted to task failure. Participants (n=12, n=6 females) completed a ramp incremental exercise test …

Human Adipose Stem Cell-Derived Small Extracellular Vesicles Modulate Glial Cell Response In Aged And Young Tbi Mouse Models, Salma S. Abdelmaboud

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) is a leading cause of long-term neurological impairment, with aging significantly increasing vulnerability and worsening outcomes. Older individuals experience greater cognitive and motor deficits after TBI and often show diminished responses to therapeutic interventions. Both aging and TBI independently promote heightened neuroinflammation and cognitive dysfunction, increasing susceptibility to poor recovery. This study investigated the therapeutic potential of small extracellular vesicles (sEVs) derived from human adipose-derived stem cells (hASCs) to promote neurological recovery and modulate neuroinflammation in a mouse model of TBI. Male C57BL/6 mice aged 3, 15, and 20 months underwent controlled cortical impact (CCI) and …
