Development, Characterization, And Optimization Of Process For Minimal Functional Barrier And Channel Width In Nitrocellulose Paper Microfluidic Diagnostic Platforms, Ryan Daniel Silva

Biomedical Engineering

A central goal of diagnostic microfluidics is to reduce the cost of diagnostic medicine by reducing the equipment and reagents needed to perform diagnostic tests. The literature has demonstrated that a wax printer can be used to pattern nitrocellulose paper with hydrophobic barriers to direct a sample in a defined reaction path, eliminating the need for external pumps and controllers. However, manufacturing methods for minimizing sample volume (and thus reagent volume) in a paper-diagnostic chip have not been well defined. In this work, we experimentally determine manufacturing processes for creating functional features of minimal size—effectively reducing the sample size and …

Absolute Quantitation For Mr Molecular Imaging Of Angiogenesis, Matthew John Goette

All Theses and Dissertations (ETDs)

Medical imaging is undergoing a transition from an art that is used to make static images of human physiology into a scientific tool that employs advanced techniques to measure clinically relevant data. Recently, the role of magnetic resonance imaging in cardiovascular and oncological research has grown, largely due to the implementation of new quantitative techniques in the clinic. Magnetic resonance imaging (MRI) and spectroscopy (MRS) are particularly rich in their capability to quantify both physiology and disease via biomarker detection. While this is true for many applications of MRI in cardiovascular and oncological research, 19F MR molecular imaging is particularly …

Toward A More Perfect Definition Of Learning: Using Biomarkers To Predict And Assess Learning Performance, Samuel J. Hunt

Dissertations

This study seeks to establish groundwork for a new definition of learning based on neurogenesis capable of guiding future educational policy and practice. The purpose of the research was to: (1) produce separate increases in neurogenesis and intelligence, (2) measure the changes in neurogenesis using protein biomarkers, and (3) correlate increases in levels of the protein biomarkers with increases in intelligence. The study employed a randomized pretest-posttest, control/comparison group research design. Thirty-eight fourth- and fifth-grade students with diverse academic needs were divided into three experimental groups: chess, exercise, and combined; with an additional control group. Pre-post measures included intelligence (RSPM) …

The Influence Of Auditory-Motor Coupling On Fractal Dynamics In Human Gait, Nathaniel Hunt, Denise Mcgrath, Nikolaos Stergiou

Journal Articles

Humans exhibit an innate ability to synchronize their movements to music. The field of gait rehabilitation has sought to capitalize on this phenomenon by invoking patients to walk in time to rhythmic auditory cues with a view to improving pathological gait. However, the temporal structure of the auditory cue, and hence the temporal structure of the target behavior has not been sufficiently explored. This study reveals the plasticity of auditory-motor coupling in human walking in relation to ‘complex’ auditory cues. The authors demonstrate that auditory-motor coupling can be driven by different coloured auditory noise signals (e.g. white, brown), shifting the …

The Second Generation Of The Cccm System For In-Vitro Cardiac Tissue Engineering., Mai-Dung Thi Nguyen

Electronic Theses and Dissertations

Cardiovascular disease is the leading cause of death worldwide. When a myocardial infarction occurs, scar tissue compensates the damaged myocardial tissue. This scar tissue increases the stiffness of the heart tissue, reduces the heart’s function, and finally leads to the heart failure (HF) disease. To have the tissue engraftment, in-vitro cardiac tissue should have the same properties as the native mature cardiac tissue. However, current in-vitro cell culture technologies fail to accurately recreate the in-vivo like mechanically physiological environment for in-vitro cardiac tissue culture, and therefore, fail to regenerate the in-vivo like mature cardiac tissue. Hence, a microfluidic cardiac cell …

No significant differencewas found betweenany of …

Conceptual Learning: Enhancing Student Understanding Of Physiology, Micah J. Waltz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Students are leaving undergraduate science programs without the knowledge and skills they are expected to have. This is apparent in professional programs, such as medical and veterinary school, where students do not possess the critical thinking skills necessary to be successful. Physiology is a required discipline for these professional programs and often before, as a pre-requisite. Physiology classrooms are an excellent place to teach critical thinking skills because the content consists of integrated processes. Therefore, in one study, it was investigated whether focusing on physiological concepts improved student understanding of physiology in both a non-physiological science course, Invertebrate Zoology, and …

Pancreatic Ribonuclease Functions As An Epidermal Growth Factor Receptor Ligand Independently Of Its Enzyme Activity And Contributes To Cetuximab Resistance, Heng-Huan Lee

Dissertations and Theses (Open Access)

Ribonuclease (RNase) with its catalytic enzyme activity to degrade RNAs has been shown as a diagnostic serum marker for pancreatic cancer and has also been suspected to have an unidentified cell surface receptor. Epidermal growth factor receptor (EGFR), a well-characterized receptor tyrosine kinase is an effective therapeutic target in multiple cancer types. However, clinical trials targeting EGFR have not demonstrated improved therapeutic efficacy in pancreatic cancer. Here, we show that both bovine pancreatic RNase A (bRNaseA) and human RNase 5 (hRNase5) act as EGFR ligands and directly activate EGFR to promote epithelial-mesenchymal transition. This ligand-like activity is independent of RNases’ …

The Percussionist Bodybuilder: Optimizing Performance Through Exercise And Nutrition, Anthony Joseph Merlino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Do preventive therapies have the potential to help avoid common injuries among percussionists? This document investigates physiological therapy and nutrition in relation to percussion performance. My interest in this subject matter is derived from my personal experiences with injuries related to the performance of percussion. Although I have studied and played percussion professionally for more than a decade, I was unaware of certain methods of rehabilitation that were available to me prior to my injuries. As I learned about the rehabilitation process through first hand experience, I discovered that my injuries were very common among percussionists. This raised the question: …

Serum Metabolomic Response Of Myasthenia Gravis Patients To Chronic Prednisone Treatment, Manjistha Sengupta, Amrita Cheema, Henry J. Kaminski, Linda Louise Kusner

Neurology Faculty Publications

Prednisone is often used for the treatment of autoimmune and inflammatory diseases but they suffer from variable therapeutic responses and significant adverse effects. Serum biological markers that are modulated by chronic corticosteroid use have not been identified. Myasthenia gravis is an autoimmune neuromuscular disorder caused by antibodies directed against proteins present at the post-synaptic surface of neuromuscular junction resulting in weakness. The patients with myasthenia gravis are primarily treated with prednisone. We analyzed the metabolomic profile of serum collected from patients prior to and after 12 weeks of prednisone treatment during a clinical trial. Our aim was to identify metabolites …

Can Anyone With Low Income Be Food Secure?: Mitigating Food Insecurity Among Low Income Households With Children In The Tampa Bay Area, Edgar Allan Amador

USF Tampa Graduate Theses and Dissertations

In the US over the last few years, approximately 14.5% of households experience food insecurity at some point throughout the year. While studies on food insecurity in the US have determined that household income and specifically income available to spend on food is of critical importance to food security, it is still unclear why some households with low income are able to maintain food security while others experience food insecurity in a pattern characterized as not constant but recurrent. This dissertation compares households with children at different levels of food security and insecurity using the USDA Core Food Security Module …

Resort Vacation Activities And Recovery Experiences: A Case Of Visitors To Thailand, Maneenuch Tanyatanaboon

Open Access Theses

An increase of work demands during workdays and sometime on the weekends can put more stress on individuals and lead to a higher need for recovery. Vacation is a prime candidate of a longer respite that can ensure a more complete recovery process because it allows individuals to temporarily take several days or weeks off without actively engaging in their job. This study thus intends to explore which activities are done upon vacation and how can they influence an individual's recovery experiences. By reviewing the theories related to recovery, vacation activities, and recreation opportunities, the study's conceptual model was developed …

Cross-Bridge Mechanisms Of Skeletal Muscle Fatigue: Effects Of Hydrogen Ion, Inorganic Phosphate, And Age, Cassandra Rae Nelson

Dissertations (1934 -)

Intense muscle contraction induces high rates of glycolysis and ATP hydrolysis with resulting increases in inorganic phosphate (Pi) and H+, factors thought to induce fatigue by interfering with steps in the cross-bridge cycle. Force inhibition is less at physiological temperatures; thus the role of low pH in fatigue has been questioned. Effects of pH 6.2 and collective effects with 30 mM Pi on the pCa-force relationship were assessed in skinned fast and slow rat skeletal muscle fibers at low (15°C) and near-physiological temperatures (30°C). At Ca2+ levels characteristic of fatigue, low pH significantly depressed force at both temperatures and in …

The first goals of this research is to determine the nominal pressure-low performance of the Jarvik pump, which is a graphical presentation of the static head and guides us about the major and minor losses in …

Diverse Convergent Evidence In The Genetic Analysis Of Complex Disease: Coordinating Omic, Informatic, And Experimental Evidence To Better Identify And Validate Risk Factors, Timothy H. Ciesielski, Sarah A. Pendergrass, Marquitta J. White, Nuri Kodaman, Rafal S. Sobota, Minjun Huang, Jacquelaine Bartlett, Jing Li, Qinxin Pan, Jiang Gui, Scott B. Selleck, Christopher I. Amos, Marylyn D. Ritchie, Jason H. Moore, Scott M. Williams

Dartmouth Scholarship

In omic research, such as genome wide association studies, researchers seek to repeat their results in other datasets to reduce false positive findings and thus provide evidence for the existence of true associations. Unfortunately this standard validation approach cannot completely eliminate false positive conclusions, and it can also mask many true associations that might otherwise advance our understanding of pathology. These issues beg the question: How can we increase the amount of knowledge gained from high throughput genetic data? To address this challenge, we present an approach that complements standard statistical validation methods by drawing attention to both potential false …

Can The Usa National Weather Service Heat Index Substitute For Wet Bulb Globe Temperature For Heat Stress Exposure Assessment?, Ivory Iheanacho

USF Tampa Graduate Theses and Dissertations

Heat stress occurs when the body cannot adequately cool itself due to the combined contributions of metabolic heat, environmental factors and clothing. Heat stress found in the workplace puts employees at risk of developing heat-related illnesses, disorders and could be fatal. The wet bulb globe temperature (WBGT) index is the current method used to assess environmental contributions to heat stress in an occupational setting. The purpose of this thesis was to explore whether the National Weather Service's Heat Index (HI) could substitute for the WBGT Index during occupational heat stress exposure assessment. The possibility of using the HI for heat …

Art Therapy And Runaway Homeless Youth: An Exploration Of Trauma And The Survival Response Of "Flight", Leann K. Marschall

LMU Theses and Dissertations

This qualitative case study examined the influencing factors of runaway behavior, trauma, and the survival response of “flight.” The participant, an 18-year-old male residing at a transitional living program, ran away at age 17 and experienced a significant trauma history. Throughout the course of treatment, artwork and clinical notes were used as data. Many themes surfaced in the analysis process, including controlled chaos, body fragmentation, sun symbols, female imagery, and lack of color. The act of running away emerged subtly, whereas, traumatic experiences, chronic in nature and beginning early in life, were acutely evident. While the study was specifically concerned …

The Effects Of Morning Versus Evening Stretching Exercises In Hamstrings Flexibility Gains, Camron Einerman, Emily Eleff, Ana Ilijeska, Aliza Zinberg

Dissertations, Theses, and Capstone Projects

Many human physiological functions, including muscle flexibility, exhibit a pattern over a 24-hour period, known as circadian rhythm. Muscle flexibility and its circadian rhythm have been researched, though much more information is needed, especially regarding the hamstring muscle group. The object of this study was to determine if stretching at different times of the day results in differences in hamstring flexibility. Since muscles and joints are most flexible at night, greater ranges of motion should be available, allowing for a greater degree of stretching to take place. We hypothesize that when utilizing the optimal type, duration, and frequency of stretch, …
