Hiv Care Location: An Evaluation Of Single Versus Multi Facility Utilization Of Hiv/Aids Care Services And Patient Health Outcomes And Clinical Indicators In South Carolina, Melanie Gwynn

Theses and Dissertations

Background: On the HIV/AIDS care continuum, the “retention in care” metric does not distinguish between single-facility (SF) or multi-clinic utilization (MC), also described as HIV care location (or type). SF utilization is vital as it has been linked optimal clinical outcomes among People Living with HIV/AIDS (PLWH). Published research detailing the prevalence of HIV care type and its association with health outcomes/clinical indicators, has been studied only in limited urban settings. Additionally, coinfections such as sexually transmitted infections (STIs), have yet to be evaluated as potential predictive factors for HIV care type.

Methods: A cross-sectional design was used …

Larval Fish Mortality And Vertical Chlorophyll Structures: Reexamination Of The Stable Ocean Hypothesis In The Southern California Current, Brendan D. Turley

Theses and Dissertations

The natural mortality of fishes is an important component for understanding population dynamics. The larval stages of pelagic fishes living in the open ocean are particularly vulnerable to high rates of mortality, and fluctuations in these rates are thought to exert a large influence on the number of fish maturing into the spawning population. Early stage larval fishes are thought to undergo a critical period after hatching when they must find food or succumb to starvation. While the availability of suitable food for larval fishes is, on average, too low in the open ocean to support survival, patchy distributions of …

Wireless Rf Induced Energy Absorption And Heating Of Lanthanum-Nickel Alloy In The Near-Field, Michael Dillon Lindsay

Theses and Dissertations

This thesis will investigate whether and how a synthetic metal-magnetic alloy absorbs enough near-field electromagnetic (EM) radiation for heating. Although resistive elements could be used for indirect heating, a wireless radio frequency (RF) method is explored because of its advantages in its non-intrusive nature and its ability to direct or focus energy within a specific area. For our case, the RF heating process relies on the materials ability to absorb sufficient RF energy due to the induced currents. We expect there to be significant surface resistance due to the conductivity and magnetic permeability of the material and thus heat. This …

Ultra-Fast Sensors To Study The Fundamental Neurochemistry Underlying Disease, Alyssa West

Theses and Dissertations

Serotonin is a vital neurotransmitter whose exact roles are ill-defined. Dysfunctions in serotonin signaling are thought to underlie a myriad of neurological problems including depression and autism spectrum disorder (ASD). Prior to investigating serotonin’s role in disease states, one must understand more about the functionality of serotonin in healthy in vivo models. To study serotonin in vivo, fast-scan cyclic voltammetry (FSCV) and fast- scan controlled adsorption voltammetry (FSCAV) are employed to measure evoked and basal serotonin concentration, respectively. These methods, combined with mathematical modeling, provide information regarding regulatory mechanisms of serotonin neurotransmission. FSCV and FSCAV are first applied to …

Susceptibility To Metabolic Disease And Individual Variations In Unfolded Protein Response In Deer Mice (Peromyscus Maniculatus), Amanda Rose Havighorst

Theses and Dissertations

The endoplasmic reticulum is the site where integral membrane and secreted proteins are synthesized and folded, and is also the site of synthesis of steroids, lipids, and other macromolecules. While ER is found in most cell types, hepatocytes in particular contain large amounts of both rough and smooth ER to facilitate their tasks, which include lipoprotein assembly and secretion, cholesterol biosynthesis, and lipid metabolism. As such, stress in the ER – and the cells’ ability to respond to it – plays a key role in disease pathogenesis. In particular, hepatic steatosis, or fatty liver, is linked to ER stress. However, …

Cdse Quantum Dot Surface Chemistry Thermodynamics Via Isothermal Titration Calorimetry: An Emphasis On The Fundamentals, Megan Y. Gee

Theses and Dissertations

For several decades, the study and development of colloidal semiconductor nanocrystals, or quantum dots (QD), has become a rich field heralding improved integration into applications ranging from photovoltaics and photocatalysis to biomedical imaging and drug delivery. CdxSey is the most extensively studied QD system, however numerous compositional details still confound the nanocrystal field. Although CdSe QDs with native ligand coatings can show high fluorescence quantum yield and may be suitable for some applications, often times these original ligand layers are comprised of long aliphatic chains that preclude incorporation into biological matrices or severely impede charge transfer – depending on the …

Phylogenetic Reconstruction Analysis On Gene Order And Copy Number Variation, Ruofan Xia

Theses and Dissertations

Genome rearrangement is known as one of the main evolutionary mechanisms on the genomic level. Phylogenetic analysis based on rearrangement played a crucial role in biological research in the past decades, especially with the increasing avail- ability of fully sequenced genomes. In general, phylogenetic analysis aims to solve two problems: Small Parsimony Problem (SPP) and Big Parsimony Problem (BPP). Maximum parsimony is a popular approach for SPP and BPP which relies on itera- tively solving a NP-hard problem, the median problem. As a result, current median solvers and phylogenetic inference methods based on the median problem all face se- rious …

Adipose Tissue Engineering: A Therapeutic Strategy For The Treatment Of Obesity And Glucose Intolerance, Michael A. Hendley

Theses and Dissertations

Despite available treatment options, the number of people afflicted by type 2 diabetes has steadily risen for decades. Nearly 90% of the diabetic population also suffers from obesity and the link between the two diseases is undeniable. Characterized by rapid expansion of the adipose tissue and improper lipid storage, the mishandling of lipids by adipose tissue promotes the diabetic state. Excess lipids, unable to be properly stored, build up in peripheral tissues promoting insulin resistance and type 2 diabetes. Therapeutic strategies designed to address adipose tissue lipid handling could represent a promising treatment strategy for obesity associated type 2 diabetes. …

Tissue-Specific Roles Of Transforming Growth Factor Beta Ligands In Cardiac Outflow Tract Malformations And Calcific Aortic Valve Disease, Nadia Al-Sammarraie

Theses and Dissertations

Congenital heart defects and adult calcific aortic valve disease are two of the leading causes of morbidity and mortality worldwide. To date, there is no medical cure and surgical intervention is the main option of treatment. The cardiac outflow tract is the major site for these abnormalities, which are triggered by genetic and/or environmental factors that alter development and/or homeostasis. Recently, significant roles of TGFβ signaling in development of cardiovascular disorders have become more evident in humans, however, the specific requirement of individual TGFβ ligands on the pathogenesis of OFT malformations and diseases remains elusive. In the present work, three …

Revisiting The Standard Soil Test: The Potential Of Macro- And Microbiological Measures To Improve Agricultural Health And Productivity, Gabriel Jacob Kenne

Theses and Dissertations

The agricultural ecosystem has become the largest non-ice-covered terrestrial ecosystem on the planet and has significant direct and indirect impacts on the global health of both the environment and humanity. Recent shifts in modern agriculture are beginning to focus on the health of soil versus a focus traditionally on crop health and yield at any cost. By managing farmland regeneratively, systems are able to reverse many of the problems created by conventional land management such as erosion and unwanted nutrient runoff, and simultaneously create opportunities to move C from the atmosphere back into the soil. While the ways in which …

Voltage-Gated Potassium Channels Are Critical For Infrared Inhibition Of Action Potentials: An Experimental Study, Junqi Zhuo, Matthew T. Mcpheeters, Michael W. Jenkins, Hillel J. Chiel

Faculty Scholarship

Thermal block of unmyelinated axons may serve as a modality for control, suggesting a means for providing therapies for pain. Computational modeling predicted that potassium channels are necessary for mediating thermal block of propagating compound action potentials (CAPs) with infrared (IR) light. Our study tests that hypothesis. Results suggest that potassium channel blockers disrupt the ability of IR to block propagating CAPs in Aplysia californica nerves, whereas sodium channel blockers appear to have no significant effect. These observations validate the modeling results and suggest potential applications of thermal block to many other unmyelinated axons.

An Interprofessional Collaborative Approach To The Development Of A Content Valid Interview Questionnaire For Persons With Hearing Loss And Their Communication Partners, Nancy A. Delich, Stephen D. Roberts

JADARA

An assessment instrument needs to be valid in order for data to be accurately interpreted and applied. Currently, few rigorous content evaluations have been conducted on hearing-related questionnaires. This study describes a multiphase approach for obtaining content validity evidence in the development of a questionnaire that explores quality of life for persons with hearing loss and their communication partners. A panel of 15 interprofessional experts evaluated 41 questionnaire items for content relevance and content clarity. Findings revealed an overall scale of .99 for content relevance and .85 for content clarity, indicating high content validity for the revised 40-item questionnaire.

Nonuniform Timeslicing Of Dynamic Graphs Based On Visual Complexity, Yong Wang, Daniel Archambault, Hammad Haleem, Torsten Moeller, Yanhong Wu, Huamin Qu

Research Collection School Of Computing and Information Systems

Uniform timeslicing of dynamic graphs has been used due to its convenience and uniformity across the time dimension. However, uniform timeslicing does not take the data set into account, which can generate cluttered timeslices with edge bursts and empty timeslices with few interactions. The graph mining filed has explored nonuniform timeslicing methods specifically designed to preserve graph features for mining tasks. In this paper, we propose a nonuni-form timeslicing approach for dynamic graph visualization. Our goal is to create timeslices of equal visual complexity. To this end, we adapt histogram equalization to create timeslices with a similar number of events, …

The Relationship Between Per Capita Income, Uninsured Rates, And Cardiovascular Mortality In Georgia Between 1994 – 2016, Monique Bethel, Mark A. Thompson, Adam E. Berman

Journal of the Georgia Public Health Association

Background: The association between cardiovascular mortality, per capita income and uninsured rates in Georgia have not been well described.

Methods: Cardiovascular mortality rates, per capita income and uninsured rates were obtained for the years 1994-2016, and their relationships were analyzed using univariate and multivariate statistical techniques.

Results: In bivariate analysis, a strong inverse relationship between cardiovascular mortality and per capita income (r = -0.917, p < 0.0001) was detected, while bivariate analysis detected no relationship between cardiovascular mortality and uninsured rates. Both per capita income and uninsured rates were negative predictors of cardiovascular mortality in multivariate analysis.

Conclusions: Per capita income increases in Georgia were strongly correlated with reductions in cardiovascular mortality. While there was not a linear correlation of healthcare coverage status and cardiovascular mortality, it demonstrated a protective effect in …

The Ethics Of Parental Refusal To Vaccinate: Costs, Community Safety, And Individual Rights, Olatanwa Adewale, Carla Cooper, Pascal Felix, Ashley K. Mitchell, Justin Savage, William A. Mase

Journal of the Georgia Public Health Association

Background: According to the World Health Organization (WHO), vaccination has reduced the burden of infectious diseases to a significant extent. In recent times, however, the focus has been more on vaccine safety rather than effectiveness. As with any other public health program, immunizations and associated policies are designed to protect the health of the public. Compared to minor risks of side effects of vaccination, the risk of infection often rationalizes the use of vaccination. In states like Georgia, with fewer outbreaks associated with non-vaccination, the need to access community immunity remains constant. Though some articles have assessed parental refusal of …

The Impact Of Maternal Literacy Skills On Child Weight In Mozambique, Ashley Watson, Shannon Self-Brown, Iris Feinberg, Whitney Rostad

Journal of the Georgia Public Health Association

Background: Infant mortality is a serious public health problem. One factor that is strongly associated with infant mortality is low weight in children. The percentage of underweight children under the age of five in Mozambique was 16% in 2012. In order to reduce the number of underweight children in this country, contributing caregiver characteristics of this problem should be investigated. One potentially relevant characteristic is maternal literacy, which has been under investigated. Objective: This study aims to determine whether maternal literacy affected the weight and body-mass-index (BMI) of children ages 0 to 3 years old in Mozambique.

The progress of science is tied to the standardization of measurements, instruments, and data. This is especially true in the Big Data age, where analyzing large data volumes critically hinges on the data being standardized. Accordingly, the lack of community-sanctioned data standards in paleoclimatology has largely precluded the benefits of Big Data advances in the field. Building upon recent efforts to standardize the format and terminology of paleoclimate data, this article describes the Paleoclimate Community reporTing Standard (PaCTS), a crowdsourced reporting standard for such data. PaCTS captures which information should be included when reporting paleoclimate data, with the goal of …
