The Effects Of Subconcussive Impacts On Postural Stability, Eric Shiflett

Electronic Theses and Dissertations

Context: The effects of concussions on postural stability, both acutely and chronically, have been well studied and noted. However, whether subconcussive impacts lead to these same impairments is not heavily investigated. Objectives: The primary purpose of this study was to examine the effects of subconcussive impacts on postural stability in NCAA Division I football athletes. We hypothesized that all participants would show declines in postural stability following a single fall season. We also hypothesized that there would be no significant differences between groups from pre- to post-season measures. The secondary purpose was to predict deficits in postural stability based on …

Evaluation Of Linear And Nonlinear Postural Stability Measurements Following Concussion, Kelsey Evans

Electronic Theses and Dissertations

Sport related concussions affect nearly 1.6 to 3.8 million athletes annually in the United States. A large number of these athletes suffer from postural instability following concussion. Postural control assessment has become a recommended tool to determine readiness to return to play. Measurement of postural control through the use of center of pressure (CoP) variables may provide a sensitive evaluation following concussion and throughout recovery. Purpose: To evaluate a unipedal and bipedal quiet stance protocol consisting of linear and nonlinear CoP measurements with varying durations in a concussed population throughout recovery. Methods: Thirteen NCAA Division I Collegiate Football players (age: …

Utilization Of B-Mode Ultrasound As A Body Fat Estimate In Collegiate Football Players, Parker Hyde

Electronic Theses and Dissertations

The purpose of the present study was to validate a 7-site ultrasound imaging protocol to predict percent body fat (%BF) in a Division I football team. Body composition was estimated by ultrasound, seven site skinfolds (SKINFOLD), and the three compartment-water (3C-W) model of Siri (1961), using Bioimpedance spectroscopy (BIS) to estimate total body water (TBW) and air-displacement plethysmography (BODPOD^®) to determine body density (Db). Pearson’s product-moment correlation analyses were run to determine between Σ_Ultrasound and the criterion 3C-W, and between the Σ_Skinfold and Σ_Ultrasound. Strong positive correlations were observed between Σ_Skinfold and Σ …

History Of Concussion And Current Functional Movement Screen Scores In A Collegiate Recreational Population, Jordan M. Dorrien

Electronic Theses and Dissertations

Introduction: 1.6-3.8 million concussions occur annually related to sport.¹ Although neurometabolic alterations in the brain last 7-10 days following a concussion, an increased Cortical Silent Period (CSP) has been found to persist after 19 months.^2,3 Further, movement impairments have been noted years after injury.⁴ The Functional Movement Screen (FMS) assesses mobility and stability in the body.⁵ The purpose of this study was to assess if FMS scores correlate to history of a concussion in healthy college club sport participants. Methods: Health history and FMS score were collected on 55 participants (38 male, …

Total Synthesis Of Biologically Active Natural And Unnatural Products, Julia Heimberger

Electronic Theses and Dissertations

Herbarin A and B were isolated from the fungal strains of Cladosporium herbarum found in marine sponges Aplysina aerophoba and Callyspongia aerizusa. Total synthesis of Herbarin A and B was achieved by carrying out a multi-step synthesis approach, and the antioxidant properties were evaluated using FRAP assay. Toxicity of these compounds was determined using a zebrafish embryo model. Furthermore, synthesis of C-6 alkyl-azaarene derivatives of nucleosides by Csp3-H bond functionalization were investigated. Effective incorporation of 2-methylazaarene moiety at the C-6 position of the protected inosine nucleoside provided a new class of compounds with anticipated enhanced biological activity.

Provider Recommendations For Human Papillomavirus Vaccine (Hpv) Among Adolescent Males In Southwest Georgia Counties And The Associated Hpv Prevalence In This Population, Benjamin K. Poku

Electronic Theses and Dissertations

Objective: The purpose of this research study was to examine the variation in healthcare providers’ behavior in recommending the Human Papillomavirus (HPV) vaccine to young male adolescents (aged 11-12), middle male adolescents (aged 13-17) and late male adolescents (aged 18-26) in rural Southwest Georgia counties. This research also aimed to identify factors associated with providers’ behaviors concerning HPV vaccination recommendation to youth in various age groups.

Methods: Upon IRB approval, secondary data were obtained from Albany Area Primary Care for a paper-based survey that was conducted in 2014 using a representative random sample of family physicians (n=12), pediatricians (n=6), and …

Examination Of Racial/Ethnic Disparities In Ovarian Cancer Stage Of Diagnosis, Surgery Treatment And Survival: Multilevel Analysis Of 2001-2012 Seer Data, Chen Chen

Electronic Theses and Dissertations

Context. Racial/ethnic disparities in cancer outcomes are major public health concerns. Ovarian cancer is the tenth most common cancer and the fifth leading cause of cancer-related deaths among women. Identifying individual- and contextual-level factors contributing to racial/ethnic disparities in ovarian cancer stage of diagnosis, surgery treatment and survival is necessary for reducing and eliminating these disparities.

Objective. The study aims to examine racial/ethnic disparities in ovarian cancer diagnosis, surgery treatment and survival outcomes; to explore individual- and contextual-level factors contributing to these disparities, and to examine the trend of ovarian cancer racial/ethnic disparities from 2001 to 2012.

Methods. The …

The Physiological Stress Response Caused By Hypoxia And Reperfusion Injury In Striped Bass (Morone Saxatilis) And Nile Tilapia (Oreochromis Niloticus), Amanda C. Reynolds

Electronic Theses and Dissertations

Approximately five million people in the United States are affected by cardiovascular related diseases yearly contributing to 300,000 annual deaths, making CVD the leading cause of mortality worldwide. It has been suggested that apoptosis (programmed cell death) contributes to the pathogenesis of cardiovascular diseases. When blood flow is reduced or cut off from the heart, usually by a thrombus, this results in oxygen deprivation (hypoxia) to the cardiomyocytes (heart cells). In response to this hypoxic stress, cardiomyocytes will undergo apoptosis. Since many species of fish can survive levels of hypoxia that would be fatal to mammals, fish are an ideal …
