Rescue Of Hearing And Protection Of Auditory Structures From Noise-Induced Hearing Loss, Reza Amanipour

USF Tampa Graduate Theses and Dissertations

Hearing loss due to exposure to high level sound is a major health problem that causes permanent hearing impairment and has a significant impact on job productivity and quality of life. A large population suffers from noise-induced hearing loss (NIHL), a disorder for which there is currently no FDA-approved prevention, treatment or cure. The goal of my dissertation work is to provide insights into the effects of noise trauma on hearing abilities of normal hearing subjects, and determine how a new therapeutic compound (mGlu7 modulator) can protect and/or prevent loss of, or damage to sensory cells and brain neurons, including …

Morphometry And Density Analysis Of The Fifth Metacarpal, Amrita Unnikumaran

USF Tampa Graduate Theses and Dissertations

The fifth metacarpal bone fracture is a common type of fracture among the young male population. With the increasing demand for early recovery from such fractures with surgical reduction, the medical manufacturers and clinicians are interested in designing a better intramedullary device for fixation. This study is an attempt to investigate the dimensional parameters of the fifth metacarpal bone and its intramedullary canal, using 3D CT scan images of cadaveric hands. The algorithm used for measurement applies principal component analysis on the subject bone, to control the information loss and normalize the spatial position of the subject. This analysis provides …

The Combined Effect Of Heat And Corona Charge On Molecular Delivery To A T-Cell Line In-Vitro, Molly A. Skinner

USF Tampa Graduate Theses and Dissertations

Gene therapy and immunotherapy are new up and coming fields in cancer treatment. In August of 2017, the first gene therapy was FDA approved called CAR-T cell therapy("FDA approval brings first gene therapy to the United States," 2017). This therapy uses the patient’s

own T-cells that are genetically modified to attack the cancerous cells. Currently, it takes 4-6 weeks to genetically modify these T-cells, which can be the difference between life and death for a cancer patient (Cheng, Jun, Jiang, & Xi, 2017). There is evidence that gene electrotransfer can help expedite the genetic modification process by having an easy …

Development And Validation Of Wireless Sensors For Applications To Human Head Angular And Mechanical Motions, Karthick Natesan

USF Tampa Graduate Theses and Dissertations

In this project, we programmed a 9 degree of freedom Razor sensor, which incorporates an accelerometer and gyroscope to measure the head linear and angular motions produced by activities of daily living (ADL). The majority of studies concentrate on linear accelerations, so the purpose of this study is to determine the importance of both linear and angular components of acceleration in everyday activities and find interlinked relation between them. The sensor was validated using another calibrated and validated system. The general size and wireless nature make this sensor very suitable for use with human subjects. After obtaining informed consent, we …

Hybrid Fusion Protein For Inhibition Of Multiple Proteases For Chronic Wound Healing, Graham L. Strauss

USF Tampa Graduate Theses and Dissertations

Many diseases display a multitude of relevant factors that contribute to the persistence of the disease and difficulty treating it. The multifactorial characteristics of some diseases lead to the requirement of combination of treatments in order to restore health. The latter may necessitate the mixing of treatments, medications, and therapeutics to first halt the disease, then assist the human body in returning itself to a state of normality. For example, chronic wounds exhibit this multifactor characteristic in which there exist many factors that lead to the body’s inability to properly heal in a timely manner. This presents a further threat …

Statistical Learning Of Biomedical Non-Stationary Signals And Quality Of Life Modeling, Mahdi Goudarzi

USF Tampa Graduate Theses and Dissertations

Statistical learning is a set of tools for modeling and understanding complex datasets. It is a recently developed area in statistics and blends with parallel developments in computer science and, in particular, machine learning.

The classification of biomedical non-stationary signals such as Electroencephalogram (EEG) is always a challenging problem due to their complexity. The low spatial resolution on the scalp, curse of dimensionality, poor signal-to-noise ratio are disadvantages of working with biomedical signals. EEG signals are unstructured data which needs preprocessing steps to extract informative features which are measurable and predictive. In the first two chapters of this dissertation, EEG …

Mhealth Elisa System For Point-Of-Care, Arsenii Zhdanov

USF Tampa Graduate Theses and Dissertations

Enzyme-linked immunosorbent assay (ELISA) is one of the most important technologies for biochemical analysis critical for diagnosis and monitoring of many diseases. Traditional systems for ELISA incubation and reading are expensive and bulky, thus cannot be used at pointof- care or in the field. Here, we design and demonstrate a new miniature mobile phone based system for ELISA. This mHealth system can be used to complete all steps of the assay, including incubation and reading. It can be fabricated at low cost, portable, and can transfer test results via mobile phone. We have designed the sample dispensing system, incubation chamber, …

Design And Development Of A Wireless Eeg System Integrated Into A Football Helmet, Akshay V. Dunakhe

USF Tampa Graduate Theses and Dissertations

In the United States, approximately 2.8 million Traumatic Brain Injuries (TBI) occur annually. Out of these 2.8 million occurrences, 280,000 injuries are caused by sports and recreational activities. The actual number can be significantly higher since mild TBI are often unrecorded. These injuries not only cause physical damage to players, but they are also one of the leading causes of a player’s retirement from a sports career. While working with TBIs, it is vital to detect the concussion at its first occurrence, termed as a “primary concussion.” If the primary concussion goes undetected, the player may continue to play the …
