An Evaluation Of The Premack Contingency To Increase Physical Activity In Teenagers With Autism Spectrum Disorder, Shreeya S. Deshmukh

USF Tampa Graduate Theses and Dissertations

The United States Department of Health and Human Services (2018) recommends that teenagers engage in physical activity to improve their cardiovascular health and muscle and bone strength. Yet, most teenagers with and without autism spectrum disorder do not meet the recommended guidelines for physical activity. Research related to promoting physical activity has evaluated group contingencies, reinforcement-based interventions, and antecedent interventions; however, these interventions are time-intensive, require many resources, or are ineffective. The purpose of this study was to extend Allen and Iwata (1980) by reinforcing completion of a low-probability exercise to a specified criterion with access to a high-probability exercise. …

The Effect Of A Contextualized Dosage Calculation Learning Intervention On Pre-Nursing Students' Math Self-Efficacy And Ability To Pass High Stakes Dosage Calculation Examination On First Attempt, Eileen V. Weatherby

Dissertations

Many students in pre-licensure nursing programs struggle with calculating accurate medication dosages even though they meet the numeracy requirements for application to the nursing programs. Most pre-licensure programs require that nursing students pass dosage calculation exams at a specified level of accuracy before progressing to the next term. Students typically have three tries to pass at the specified level and should they not succeed, they must withdraw. If they wish to continue in the program, they must complete the requirements for reentry which may include space availability restrictions. Factors influencing dosage calculation performance include fear of mathematics, low math self-efficacy, …

Abstract: The rapidly aging population is consuming more alcohol, leading to increased alcohol-associated acute pancreatitis (AAP) with high mortality. However, the mechanisms remain undefined, and currently there are no effective therapies available. This study aims to elucidate aging- and alcohol-associated spatial transcriptomic signature by establishing an aging AAP mouse model and applying Visium spatial transcriptomics for understanding of the mechanisms in the context of the pancreatic tissue. Upon alcohol diet feeding and caerulein treatment, aging mice (18 months) developed significantly more severe AAP with 5.0-fold increase of injury score and 2.4-fold increase of amylase compared to young mice (3 months). …

Loss Of Hormone Receptor Expression After Exposure To Fluid Shear Stress In Breast Cancer Cell Lines, Jonathan Cuccia, Braulio Andres Ortega Quesada, Ethan P. Littlefield, Alejandra M. Ham, Matthew E. Burow, Adam T. Melvin, Elizabeth C. Martin

School of Medicine Faculty Publications

Following metastatic spread, many hormone receptor positive (HR(+)) patients develop a more aggressive phenotype with an observed loss of the HRs estrogen receptor (ER) and progesterone receptor (PR). During metastasis, breast cancer cells are exposed to high magnitudes of fluid shear stress (FSS). Unfortunately, the role for FSS on the regulation of HR expression and function during metastasis is not fully understood. This study was designed to elucidate the impact of FSS on HR(+) breast cancer. Utilizing a microfluidic platform capable of exposing breast cancer cells to FSS that mimics in situ conditions, we demonstrate the impact of FSS exposure …

Chemotherapy Drug Release From Hollow Core Polyethyleneimine Nanoparticles, Brian Boyle

Theses and Dissertations

Novel anticancer delivery vehicles are arising from engineered nanostructured materials. This work involved the synthesis, characterization, and release of novel hollow core polymeric nanoparticles (HCPNPs) for controlled drug delivery. Polyethyleneimine (PEI) was bound to AuNPs, forming polymer-shell nanoparticles with dissolution of the gold core via iodine forming HCPNPs with drug intercalated DNA bound to the surface. A high density (85 molecules/particle) of DNA intercalated with daunorubicin was conjugated. Particles were spherical with an average diameter of 105.7 ± 17.3 nm and zeta potential of 20.4 ± 3.54 mV. We hypothesize the DNA backbone electrostatically condensed to the primary amines on …

How can short-lived molecules selectively maintain the potentiation of activated synapses to sustain long-term memory? Here, we find kidney and brain expressed adaptor protein (KIBRA), a postsynaptic scaffolding protein genetically linked to human memory performance, complexes with protein kinase Mzeta (PKMζ), anchoring the kinase's potentiating action to maintain late-phase long-term potentiation (late-LTP) at activated synapses. Two structurally distinct antagonists of KIBRA-PKMζ dimerization disrupt established late-LTP and long-term spatial memory, yet neither measurably affects basal synaptic transmission. Neither antagonist affects PKMζ-independent LTP or memory that are maintained by compensating PKCs in ζ-knockout mice; thus, both agents require PKMζ for their effect. …

Inhibition of wax deposition using chemical methods involves using chemical additives to prevent or reduce wax buildup on pipelines or wellbores. Chemical methods for mitigating wax deposition can include using plant-based inhibitors as effective additives. Biosurfactants, which are surfactants derived from plant-based sources, can be used in chemical methods …

Dynamic Modeling And Tracking Of 3-Wheels Omni-Directional Mobile Robot With Manual Pid Tuning Method, Soe Soe Htay, Khaing Win Phyu, Su Yadanar, Wut Yi Win, Min Thu Soe

Platform: A Journal of Engineering (PAJE)

This paper presents the dynamic modelling and tracking control of a holonomic 3-wheel omni-directional mobile robot. A proportional integral derivative (PID) controller is used, and its performance depends on the dynamic model’s accuracy. The controller design for the switched non-linear system is based on both a dynamic model and a kinematic design. A proposed dynamic model averages the contact radius of the 3-wheels. The resultant dynamic model, on average, is non-linear and smooth, serving as a potential solution for model-based control design. The closed-loop simulation results clearly illustrate the dynamic characteristics of the 3-wheels omni-directional mobile robot, offering valuable insights …

Evaluating The Impact Of A 2-Week Peer Enhanced E-Placement (Peep) On Pre-Registration Physiotherapy Students’ Attitudes, Self-Perceived Confidence, And Competence In Delivering Telerehabilitation., Christie Robinson, Sarah Buckingham, Jennifer Freeman

School of Health Professions

The COVID-19 pandemic brought about rapid digital transformation of physiotherapy practice and education. Previous studies have suggested a lack of knowledge, beliefs, and clinical acceptance of telerehabilitation as barriers to implementation and sustainability of telerehabilitation. Providing pre-registration specific teaching and practical experience of telerehabilitation may improve physiotherapy student confidence and competence in delivering telerehabilitation and support clinical acceptance of telerehabilitation in practice. A 2-week Peer Enhanced E-Placement (PEEP) was developed and evaluated to explore its impact on third year physiotherapy student attitudes, and perceived competence and confidence in delivering telerehabilitation. Students completed a Likert scale questionnaire, immediately pre and post …

Efforts to develop targetable molecular bases for drug resistance for pancreatic ductal adenocarcinoma (PDAC) have been equivocally successful. Using RNA-seq and ingenuity pathway analysis we identified that the superpathway of cholesterol biosynthesis is upregulated in gemcitabine resistant (gemR) tumors using a unique PDAC PDX model with resistance to gemcitabine acquired in vivo. Analysis of additional in vitro and in vivo gemR PDAC models showed that HMG-CoA synthase 2 (HMGCS2), an enzyme involved in cholesterol biosynthesis and rate limiting in ketogenesis, is overexpressed in these models. Mechanistic data demonstrate the novel findings that HMGCS2 contributes to gemR and confers metastatic properties …

Little is known about risk factors for central nervous system (CNS) relapse in mature T-cell and natural killer cell neoplasms (MTNKNs). We aimed to describe the clinical epidemiology of CNS relapse in patients with MTNKN and developed the CNS relapse In T-cell lymphoma Index (CITI) to predict patients at the highest risk of CNS relapse. We reviewed data from 135 patients with MTNKN and CNS relapse from 19 North American institutions. After exclusion of leukemic and most cutaneous forms of MTNKNs, patients were pooled with non-CNS relapse control patients from a single institution to create a CNS relapse-enriched training set. …

Inflammation and tissue damage associated with pancreatitis can precede or occur concurrently with pancreatic ductal adenocarcinoma (PDAC). We demonstrate that in PDAC coupled with pancreatitis (ptPDAC), antigen-presenting type I conventional dendritic cells (cDC1s) are specifically activated. Immune checkpoint blockade therapy (iCBT) leads to cytotoxic CD8+ T cell activation and elimination of ptPDAC with restoration of life span even upon PDAC rechallenge. Using PDAC antigen-loaded cDC1s as a vaccine, immunotherapy-resistant PDAC was rendered sensitive to iCBT with elimination of tumors. cDC1 vaccination coupled with iCBT identified specific CDR3 sequences in the tumor-infiltrating CD8+ T cells with potential therapeutic importance. This study …

The Utilisation Of Rice Husk Ash Leachates For The Synthesis Of Eco-Friendly Geopolymers, Maria Kaka Etete Enoh, Oliver Ibor Inah

Platform: A Journal of Engineering (PAJE)

Geopolymers are inorganic polymers projected as feasible alternatives to Portland cement due to their lower CO2 emissions and high mechanical properties. In recent times, however, their impact on other environmental indices such as abiotic depletion, freshwater toxicity, marine ecotoxicity, terrestrial ecotoxicity, acidification, and human toxicity has become questionable, thus the need to investigate alternative eco-friendly precursors and activators. This work aims to manufacture an eco-efficient geopolymer by utilising biomass ash leachate as an alternative to the conventional alkali silicate solution. The leachate was obtained by soaking the rice husk ash (RHA) in a 10 M concentration of NaOH solution and …

Polyurethane-Asphaltic Concrete As An Alternative Solution For Road Pavement Distress - A Review, Diana Che Lat, Atiqah Najwa Zainuddin, Siti Nur Aishah Mohd Noor, Doris Asmani Mat Yusof, Ismacahyadi Bagus Mohamed Jais

Platform: A Journal of Engineering (PAJE)

Road traffic accidents are the primary source of injuries and fatalities worldwide, accounting for 20–50 million long term disabilities and 1.25 million deaths annually. Pavement conditions ranked as the second most common cause of traffic accidents. The combined effects of environmental factors and traffic loads lead to pavement discomfort. Ensuring proper pavement design and maintenance can assist in reducing accident rates and preventing long-term disability associated with drivers. Physical maintenance procedures like overlays, seal coatings, patching, and filling joints are carried out in practice; nevertheless, they only offer temporary fixes by treating the symptoms rather than the underlying issue. An …

3d Organ-Scale Models Of Tumor Growth And Treatment, Rafael Ramon Bravo

USF Tampa Graduate Theses and Dissertations

To understand the dynamics of cancer, mathematical oncologists have developed models of tumor growth and treatment response. Some models are mechanistic and approach tumor growth at the cell-scale, focusing on the evolution of cancerous cells within the ecology of normal tissue, and are often simulated with agent-based modeling. Other models are more clinically motivated and model tumor growth operating at the organ-scale, using patient data to predict treatment response, and are often simulated with partial differential equations. We developed the Hybrid Automata Library which includes both agent-based modeling and partial differential equations for modeling at either of these scales. We …

Physiological And Circadian Outcomes Of Fkbp5 Imbalance: Insights From Two Models, Niat Tsegai Gebru

USF Tampa Graduate Theses and Dissertations

Circadian rhythms are crucial in regulating various physiological processes, including mood regulation, and disruptions in these rhythms have been linked to several neuropsychiatric disorders, such as depression, bipolar disorder, and schizophrenia. FKBP51, a protein involved in stress responses and glucocorticoid receptor function has emerged as a potential regulator of the circadian clock. FKBP51’s interaction with glucocorticoid receptors impacts the transcriptional regulation of circadian-related genes. In recent years, FKBP51 has been associated with genetic and epigenetic alterations in neuropsychiatric disorders, highlighting its potential as a target for intervention. The heterogeneity associated with neuropsychiatric disorders arises from a combination of genetic, environmental, …

Randomized Controlled Trial Of Enteral Vitamin D Supplementation (Vides) In Infants <28 Weeks Gestational Age Or <1000 G Birth Weight: Study Protocol, Mar Romero-Lopez, Jon E Tyson, Mamta Naik, Claudia Pedroza, Lindsay F Holzapfel, Elenir Avritscher, Ricardo Mosquera, Amir Khan, Matthew Rysavy

Faculty, Staff and Student Publications

BACKGROUND: Vitamin D is necessary to develop healthy lungs and other organs early in life. Most infants born before 28 weeks' gestation have low vitamin D levels at birth and a limited intake during the first month. Enteral vitamin D supplementation is inexpensive and widely used. The appropriate supplementation regimen for extremely preterm infants is controversial, and the effect of different regimens on their blood levels and outcomes is unclear.

METHODS: Randomized, blinded comparative effectiveness trial to compare two vitamin D supplementation regimens for inborn infants(400 IU/day with established feedings) or increased supplementation (800 IU/day with any feedings) during the …

In Situ Diffuse Reflectance Spectroelectrochemistry Of Cathode Materials In Lithium-Ion Batteries, Lu-Lu Chen, Hao-Ran Li, Wei-Yi Liu, Wei Wang

Journal of Electrochemistry

Developing in situ spectroelectrochemistry methods, which can provide detailed information about species transformation during electrochemical reactions, is very important for studying electrode reaction mechanisms and improving battery performance. Studying real-time changes in the surface of electrode materials during normal operation can be an effective way to assess and optimize the practical performance of electrode materials, thus, in situ and in operando characterization techniques are particularly important. However, batteries are hard to be studied by in situ characterization measurements due to their hermetically sealed shells, and there is still much room for battery characterizations. In this work, a specially designed battery …
