Rebound Bursting Selectively Enables Fast Dynamics In Dopamine Midbrain Neurons Projecting To The Dorsolateral Striatum, Strahinja Stojanovic, Christopher J. Knowlton, Richard Egger-Mackrodt, Johanna Mankel, Josef Shin, Stephan Lammel, Carmen C. Canavier, Jochen Roeper

School of Graduate Studies Faculty Publications

Dopamine (DA) midbrain neurons are involved in a wide array of key brain functions including movement control and reward-based learning. They are also critical for major brain disorders such as Parkinson's disease or schizophrenia. DA neurons projecting to distinct striatal territories are diverse with regard to their molecular makeup and cellular physiology, which are likely to contribute to the observed differences in temporal DA dynamics. Among these regions, the dorsolateral striatum (DLS) displays the fastest DA dynamics, which might control the moment-to-moment vigor and variability of voluntary movements. However, the underlying mechanisms for these DLS-specific fast DA fluctuations are unresolved. …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

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 …

Incorporating Balance Training Into Ankle Sprain Injury Prevention Programs: An Evidence-To-Practice Review, David Tomchuk, Jacob Meyer, Kyle Schneider, Ben Fox

Clinical Practice in Athletic Training

Ankle sprains are among the most common injuries in sports and non-sporting activities. For patients, ankle sprains can result in multiple short and long-term hardships, such as financial burdens of evaluation and treatment, absenteeism from sport and physical activity, and diminished ankle and lower extremity function. However, athletic trainers and other stakeholders are also impacted by administrative and time burdens in caring for ankle sprains and how ankle sprains affect team dynamics and performance. The 2022 guiding systematic review evaluated the effectiveness of incorporating preventive balance training exercises on the incidence of ankle sprains in soccer athletes. The search performed …

Impact Of A Focused Best Practice Workshop On Athletic Trainer Confidence, Jaclyn B. Arduini, Jennifer L. Volberding, Zachary A. Murray

Clinical Practice in Athletic Training

Athletic trainers are required to be proficient in emergency management skills, without review these skills may decay creating a potentially dangerous knowledge gap. Confidence measures of emergency management skills were taken before and after a workshop to determine if they changed due to the review of material. All 11 confidence measures increased post workshop, seven significantly, including rectal temperature, hemostatic agents, external hemostatic modalities, in-line stabilization, measurement and application of a cervical collar, football and other equipment removal. ATs should aim to incorporate emergency management review into continuing education choices.

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

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 …

A Novel Sialylation Pathway Mediated By Extracellular Vesicles In Aggressive Prostate Cancer, Camila A. Bach, Md Niamat Hossain, Ishan J. Chaudhari, Cecilia E. Verrillo, Nicole M. Naranjo, Isabella Amoroso, Anna Testa, Samuel Sey, W. Kevin Kelly, Susan L. Bellis, Aurelio Lorico, Ada G. Blidner, Gabriel A. Rabinovich, Lucia R. Languino

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

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 …

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 …

Nadph Oxidase Isoforms (Nox-2 And Nox-4) In Myocardial Ischemia/Reperfusion Injury: Platelet Rich Plasma (Prp) As A Therapeutic Agent, Barbara Y. Hargrave, Frank Lattanzio

Cardiovascular Research Symposium

Introduction: Blood flow restoration to ischemic cardiac tissue is a critical and necessary intervention that has an associated downside: reperfusion injury. Reperfusion injury is a complicated process mediated in part by a pathological increase in reactive oxygen species (ROS). Although extremely elevated levels of ROS can cause cell damage, a minimum level of ROS is necessary for activation of Hydroxylated-HIF-1a (HIF-1a) and inhibition of Peroxisome Proliferator-Activated Receptor-alpha (PPARa) during myocardial ischemic reperfusion injury (MIRI). MIRI clinical manifestations include arrhythmias, myocardial stunning, decreased ventricular contractility and no-reflow. Platelet rich plasma (PRP) has improved left ventricular (LV) function after MIRI in …

Mako: NSU Undergraduate Student Journal

Many preoperative and postoperative cataract patients struggle with comprehending the use of prescription medication as directed. Language barriers and low health literacy levels are major factors contributing to improper use of prescriptions. To increase patients comprehension, the Fort Lauderdale Eye Institute employed an educational intervention consisting of a live presentation and an instructional video. Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

Asymmetric Fgf Receptor Dimerization: Implications For Fgf23 Biology And Drug Discovery, Mohammed S. Razzaque, Moosa Mohammadi

School of Medicine Publications

Fibroblast growth factor 23 (FGF23) requires both αKlotho and heparan sulfate proteoglycans (HSPGs) as obligatory coreceptors to bind, dimerize, and activate its FGF receptors (FGFRs) in the kidney, thereby regulating mineral ion and vitamin D homeostasis. Cryogenic electron microscopy studies reveal that FGF23 signaling proceeds through an asymmetric 1:2:1:1 FGF23–FGFR–αKlotho–HS assembly. According to this structural model, αKlotho simultaneously anchors FGF23 and one FGFR chain, referred to as the primary receptor (FGFRP), to form a 1:1:1 FGF23-FGFRP-αKlotho triplex, which boosts FGF23-FGFRP interaction. Subsequently, the HS coreceptor aids the triplex in recruiting a second FGFR chain, or secondary receptor (FGFRS), leading to …

Effects Of Body Armor On Respiratory Muscle Fatigue And Muscle Blood Flow During Progressive Treadmill Marching, Kathryn Bell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Torso-borne loads such as body armor are essential for modern military operations but impose mechanical and metabolic strain. These physiological stressors can trigger the inspiratory metaboreflex, which redirects blood flow from locomotor to respiratory muscles, further reducing muscle oxygen and endurance. While aerobic fitness has been shown to alleviate these effects, the interaction between sex, aerobic capacity, and oxygenation under load is not well understood. This study examined the physiological effects of torso-borne load carriage on respiratory muscle fatigue, skeletal muscle oxygenation, and exercise performance to volitional exhaustion and the degree to which sex and aerobic capacity influence these …

An Analysis Of The Influence Of Human Disease Pathogens On Core Behaviors Of The Black-Legged Tick, Emily F. Marinko

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ixodes scapularis, the black-legged or deer tick, is a vector for several different disease-causing microbes, including the causative agent of Lyme disease. As such, it is a major health concern for people living within its range in the eastern half of the United States, a habitation area that is increasing due to climate change. Despite its medical relevance as a disease vector, there is still much to learn about the basic behavior of these arachnids in the wild. Thus, the major hypothesis of this thesis is that ticks that are infected with specific human disease-causing microbes behave differently than those …

Pearson’s correlation coefficients and Shapiro-Wilk tests revealed that …

Advanced Interactions Of Directed Energy With Retinal Pigment Epithelial Cells And Their Photochemical And Photothermal Responses, Jin B. Ha

Theses & Dissertations

Excess optical radiation can injure the retina through either rapid heat deposition (photothermal damage) or cumulative photo‑oxidative stress (photochemical damage), yet current laser‑safety limits treat these mechanisms as independent. To test that assumption, this dissertation integrated systematic wavelength, duration and temperature‑controlled laser exposures with live/dead fluorescence imaging in a melanin‑loaded hTERT‑RPE1 monolayer model. First, concurrent 447 nm (blue) and 2 µm (infra‑red) beams delivered for 200 s demonstrated a strong thermal–photochemical synergy: each beam alone was sub‑threshold (≤25 % lethality) but together produced 100 % RPE death without exceeding 50 °C, proving that modest heating markedly lowers the photon dose …

The Effect Of An Acute Bout Of Rock Climbing On Cognitive Functioning And Cortisol Levels, Vanessa Steigauf

All NMU Master's Theses

Rock climbing is an understudied physical activity (PA) that demands active decision-making, integration of sensory and visual input, and continuous regulation of nervous system activity to produce complex motor outputs. The unique psychological demands of climbing warrant studying its effect on cognition and brain health. I recruited 26 generally healthy adults for a randomized-controlled study. Climbing experience, PA and perceived stress were self-reported. Each participant was randomly assigned to a climbing (10x2 minutes climb, moderate intensity) or control group (seated, watching climbing-related video). The primary outcomes, cognitive performance and salivary cortisol levels were assessed by the Stroop test. A linear …
