Kinematic And Spatiotemporal Analysis Between Sprint Drills And Maximal Sprinting, Julianne Cappadona
Kinematic And Spatiotemporal Analysis Between Sprint Drills And Maximal Sprinting, Julianne Cappadona
PTHMS Undergraduate Publications
Purpose: To determine if any kinematic differences exist between two common sprint drills (A- and B-drills) and maximal sprinting. Methods: 12 collegiate sprinters (19.17±1.11 y/o) granted informed consent were filmed performing two 40-meter sprints, A-skips, and B-skips. Three-dimensional motion analysis tracked the coordinates of 24 reflective markers and resulting joint kinematics were computed. Results: Statistical analysis revealed that sprinting yielded a significantly lower maximum hip flexion (p=0.015) but a significantly higher minimum ankle angular velocity (p=0.012) and step rate (p=0.000) value than A-drills. When compared to B-drills, sprinting values were significantly lower in maximum hip flexion (p=0.047), minimum knee flexion …
Automated Point-Of-Care Image Processing Methodology For The Diagnosis Of Malaria, Michael B. Jorgensen
Automated Point-Of-Care Image Processing Methodology For The Diagnosis Of Malaria, Michael B. Jorgensen
Master's Theses
Malaria has profoundly influenced human history for over four thousand years and despite numerous attempts at eradication, the prevention, diagnosis, and treatment of malaria have been largely ineffective. More than five hundred million people are affected by malaria every year resulting in over one million deaths. Drug resistance development by the parasite has diminished the effectiveness of numerous treatment options due, in part, to overtreatment of negative patients based on insufficient clinical algorithms and diagnostic methods. The goal of this research was to develop an image analysis algorithm to diagnose malaria with a high degree of sensitivity and specificity in …
Noninvasive Near-Infrared Diffuse Optical Monitoring Of Cerebral Hemodynamics And Autoregulation, Ran Cheng
Noninvasive Near-Infrared Diffuse Optical Monitoring Of Cerebral Hemodynamics And Autoregulation, Ran Cheng
Theses and Dissertations--Biomedical Engineering
Many cerebral diseases are associated with abnormal cerebral hemodynamics and impaired cerebral autoregulation (CA). CA is a mechanism to maintain cerebral blood flow (CBF) stable when mean arterial pressure (MAP) fluctuates. Evaluating these abnormalities requires direct measurements of cerebral hemodynamics and MAP. Several near-infrared diffuse optical instruments have been developed in our laboratory for hemodynamic measurements including near-infrared spectroscopy (NIRS), diffuse correlation spectroscopy (DCS), hybrid NIRS/DCS, and dual-wavelength DCS flow-oximeter. We utilized these noninvasive technologies to quantify CBF and cerebral oxygenation in different populations under different physiological conditions/manipulations. A commercial finger plethysmograph was used to continuously monitor MAP. For investigating …
Development Of A Patient Specific Image Planning System For Radiation Therapy, Bishnu Bahadur Thapa
Development Of A Patient Specific Image Planning System For Radiation Therapy, Bishnu Bahadur Thapa
Theses and Dissertations--Physics and Astronomy
A patient specific image planning system (IPS) was developed that can be used to assist in kV imaging technique selection during localization for radiotherapy. The IPS algorithm performs a divergent ray-trace through a three dimensional computed tomography (CT) data set. Energy-specific attenuation through each voxel of the CT data set is calculated and imaging detector response is integrated into the algorithm to determine the absolute values of pixel intensity and image contrast. Phantom testing demonstrated that image contrast resulting from under exposure, over exposure as well as a contrast plateau can be predicted by use of a prospective image planning …

Practitioners' Use Of Clinical Practice Guidelines: An Evidence-Based Approach, Sondra Michelle Phipps Santana
UNF Graduate Theses and Dissertations
Pre-diabetes is a serious health problem in the United States. Distinguished by plasma glucose levels that are above the normal threshold, patients with pre-diabetes are 10 times more likely to develop type 2 diabetes. Patients with pre-diabetes suffer the same complications as patients with diabetes including diabetic retinopathy, nephropathy, and microalbuminuria.
There is considerable evidence to support the idea that early identification and aggressive treatment of pre-diabetes has the potential to delay disease progression. The American Diabetes Association’s clinical practice guideline recommends management of with lifestyle modification and metformin for patients who are at risk for developing type 2 diabetes. …

Generation And Characterization Of Peptide Fusion Proteins, Brianna L. Probasco
Generation And Characterization Of Peptide Fusion Proteins, Brianna L. Probasco
Graduate School of Biomedical Sciences Theses and Dissertations
Pathogenic Th17 cells drive progression of many autoimmune diseases. Th17 cells develop from naïve T cells in the immune system after antigen-driven stimulation in a specific cytokine environment. Normally, T cells act to fight off infection, but when not properly controlled, they can cause disease. The cytokine interleukin-23 (IL-23) plays an essential role in the expansion of pathogenic Th17 cells. IL-23 is a heterodimeric protein, composed of a p19 alpha chain and a p40 beta chain. The p40 is also part of IL-12 and binds to the IL-12 receptor beta 1 (IL-12Rβ1) subunit. Thus, it follows that the IL-23 receptor …

A Dna Computer For Glioblastoma Multiforme Diagnosis And Drug Delivery, Sumaiya F. Hashmi
CMC Senior Theses
Glioblastoma multiforme (GBM) is a debilitating malignant brain tumor with expected patient survival of less than a year and limited responsiveness to most treatments, often requiring biopsy for diagnosis and invasive surgery for treatment. We propose a DNA computer system, consisting of input, computation, and output components, for diagnosis and treatment. The input component will detect the presence of three GBM biomarkers: vascular endothelial growth factor (VEGF), caveolin-1α (CAV), and B2 receptors. The computation component will include indicator segments for each of these genes, and ensure that output is only released if all the biomarkers are present. The output component …

Magnetocardiography In Unshielded Environment Based On Optical Magnetometry And Adaptive Noise Cancellation, Valentina Tiporlini
Theses: Doctorates and Masters
This thesis proposes and demonstrates the concept of a magnetocardiographic system employing an array of optically-pumped quantum magnetometers and an adaptive noise cancellation for heart magnetic field measurement within a magnetically-unshielded environment.
Optically-pumped quantum magnetometers are based on the use of the atomic-spin-dependent optical properties of an atomic medium. An Mxconfiguration- based optically-pumped quantum magnetometer employing two sensing cells containing caesium vapour is theoretically described and experimentally developed, and the dependence of its sensitivity and frequency bandwidth upon the light power and the alkali vapour temperature is experimentally demonstrated. Furthermore, the capability of the developed magnetometer of measuring very weak …
Choice Response Time Differences Between Recently Recovered Concussed And Healthy Student-Athletes, Tiffen Tapia-Lovler
Choice Response Time Differences Between Recently Recovered Concussed And Healthy Student-Athletes, Tiffen Tapia-Lovler
Electronic Theses and Dissertations
Some 1.6 to 3.8 million sports-related concussions occur annually in the United States. Utilization of test batteries and exercise protocols are recommended to ensure athletes recover completely. Many batteries involve response time (RT) tests, which show response time increases post concussion. A major limitation of RT tests is that all are done in static position. Additionally, many studies show a lingering effect on RT. The addition of RT tests to check for lingering symptoms could be beneficial. The purpose of this study was to see if significant differences could be found in RT tests involving dynamic movement between healthy studentathletes …
