Optimization Of Treatment Of Chlorinated Volatile Organic Compound Mixtures In Constructed Wetlands: Vegetation And Substrate Effects, Stephen Emmanuel Mbuligwe

LSU Doctoral Dissertations

Microcosm and mesocosm scale experiments were carried out to investigate the effects of vegetation and substrates on the performance of engineered wetland systems (EWSs) meant to treat mixtures of volatile organic compounds (cVOCs). The experiments were conducted with a view to optimizing contributions of these wetland components. Phragmites communis and Typha latifolia, the commonest wetland plant species, were compared in mesocosm scale EWSs. Eight common wetland plant species were compared using microcosm experiments based on the potential of their rootmatter to enhance treatment of cVOC mixtures. Twelve common wetland plants were similarly compared but on the basis of their aboveground …

Brachial Artery Flow Mediated Vasodilation: Effect Of Chemical Analytes, Diet, Exercise, And Genetic Markers, Joanie Brocato Wilson

LSU Doctoral Dissertations

The goal of this research was to gain a better understanding of interplay between molecular biology, physiology, biochemistry, functionality with disease and interventions. The primary findings of the first study were that there was a significant inverse correlation between homocysteine and brachial artery flow mediated dilation (BAFMD) and baseline brachial artery diameter. Interestingly, there was a significant difference in BAFMD between methylene tetrahydrofolate reductase (MTHFR) genotype groups. Regression analysis indicated that the MTHFR genotype, homocysteine and age were significant predictors of BAFMD. The second study revealed that vascular reactivity as measured by BAFMD was modifiable. A meta-analysis of 22 intervention …

Randomized Controlled Trial Evaluating Adeno-Momp And Momp Dna Vaccines Against Chlamydophila Psittaci Challenge In Cockatiels (Nymphicus Hollandicus), David Sanchez-Migallon Guzman

LSU Master's Theses

Chlamydophila psittaci causes severe disease in birds and humans, and important economical losses in the avian companion and poultry industry. Vaccines are the most cost-effective measure to control and help prevent infectious diseases, but to date there is no commercial vaccine available. A randomized clinical trial was conducted to assess the efficacy of two recombinant DNA vaccines against C. psittaci in Cockatiels (Nymphicus hollandicus). The first recombinant DNA vaccine has a gene encoding MOMP and the immunostimulant chitosan (MOMP DNA vaccine). The second recombinant DNA vaccine, contained the gene encoding MOMP that was vectored by a replication defective human adenovirus …

Comorbidity Of Pediatric Migraine And Sleep Disturbances: The Role Of A Dysfunctional Autonomic Nervous System, Debra B. Huss

University of Kentucky Doctoral Dissertations

This study compared psychological and physiological differences between children diagnosed with migraine and their healthy peers. Physiological measures were obtained at baseline, after discussing an emotionally relevant stressor, and after recovery in 21 children with pediatric migraine and 32 healthy peers. Comparisons were also made on psychological measures investigating sleep problems, anxiety, and family stress. It was hypothesized that children with migraine compared to their peers 1) would report more sleep disturbances, anxiety, and family stress 2) would exhibit greater sympathetic activation at rest, in response to an emotional stressor, and after a recovery period and 3) that autonomic functioning …

Tikkun Olam A Faith-Based Approach For Assisting Older Adults In Health System Navigation, Janice M. Kuperstein

University of Kentucky Doctoral Dissertations

The complexity and lack of coordination of the U.S. health care system is especially challenging for older adults, many of whom have multiple chronic conditions. The faith community is a potential partner to assist them, due to strong religiosity of older adults and specific characteristics of faith communities. This study explores the knowledge and practices of faith community nurses (FCNs) in meeting care coordination needs of older adults and identifies a model of gap-filling by FCN practice. An approach combining both quantitative and qualitative approaches was used. A survey was distributed to all known FCNs in Kentucky. From the 60 …

Regulation Of L-Type Voltage-Dependnet Calcium Channels By The Rem Gtpase, Chunyan Pang

University of Kentucky Doctoral Dissertations

The Rem, Rem2, Rad, and Gem/Kir GTPases, comprise a novel subfamily of the small Ras-related GTP-binding proteins known as the RGK GTPases, and have been shown to function as potent negative regulators of high voltage-activated (HVA) Ca²⁺ channels upon overexpression. HVA Ca²⁺ channels modulate Ca²⁺ influx in response to membrane depolarization to regulate a wide variety of cellular functions and they minimally consist of a pore-forming α1 subunit, an intracellular β subunit, and a transmembrane complex α₂/δ subunit. While the mechanisms underlying RGK-mediated Ca²⁺ channel regulation remain poorly defined, it appears that both membrane …

Elucidating Marine Pore Water Exchange And Fresh Aquifer Sources In Estimates Of Submarine Groundwater Discharge To A Coastal Lagoon, Christopher Gerald Smith

LSU Doctoral Dissertations

Dynamic balances between fresh groundwater, saline groundwater, and surface water control the physics and chemistry of subterranean estuaries. Investigations were performed in a subterranean estuary on physical processes contributing to fresh groundwater and saline water mixing, vertical and lateral positioning of this mixing zone, and how this mixing affects spatial and temporal distributions of ^234,238U, ²²⁶Ra, and ²²²Rn. The subterranean estuary is located in an unconfined aquifer beneath Indian River Lagoon, Florida, USA, where I could examine redox responses to altered flow regimes. Continuous groundwater and surface water level measurements suggest a strong hydrologic connection between this …

The Relationship Between Pro-Inflammatory Cytokines, Prostaglandins, And Fetal Hypothalamic-Pituitary-Adrenal Axis Activation In Mares With Infective Pre-Term Delivery, Sara K. Lyle

LSU Doctoral Dissertations

Ascending placentitis is a significant cause of abortions, stillbirths, and perinatal loss in horses. A technique for laparoscopic-guided catheterization of the allantoic space was developed and utilized in an experimental model of streptococcal infective pre-term delivery in pony mares. Mares received either 1 x 107 CFU live S. zooepidemicus (n=3), 5.1 x 108 CFU live S. zooepidemicus (n=1), 1 x 107 heat-killed S. zooepidemicus (n=3), 1 mL sterile PBS (n=3). Sham control mares did not receive a transcervical inoculation (n=3). One mare not instrumented with an allantoic catheter received 5.1 x 108 CFU live S. zooepidemicus. Mares with spontaneous abortion …

Modeling And Synergy Testing Of Drug Combination Data: A Pharmacokinetic Analysis, Jacy Rebecca Crosby

UNF Graduate Theses and Dissertations

In this paper, we present and implement a method to assess the mathematical synergy of two-drug combinations based on a stochastic model. The drugs in question are two isomers that are applied to the human eye via a liquid eye drop. Techniques applied to the data in this paper can be applied to other two-drug combination studies.

We derive the mean and the variance terms of the drug combination "effects" in closed form using Ito's method of stochastic differential equations. The model fit of the data to the individual subject is examined by both statistical and graphical methods. Two estimation …

Phylogenetics And New Approaches To Vaccine Development For West Nile, Arun Venkatesh Iyer

LSU Doctoral Dissertations

West Nile virus (WNV) was first isolated in 1937 from a febrile Ugandan woman. WNV now has a worldwide distribution from Australia and India in the east to Europe and the United States in the west. The first human cases of WNV in the United States were detected in New York in 1999. The North American isolates were also found to be highly neuroinvasive and neurovirulent and in many cases leading to mortality or permanent CNS sequelae among humans. WNV was first isolated in Louisiana in 2001. The genome of this virus named LSU-AR01was sequenced and a detailed genetic analysis …

Assessing Interest Groups: A Playing Field Approach, Paul Stancil

Faculty Scholarship

Despite general public antipathy toward the political influence exerted by corporations, industries, and other special interests, prescriptive applications of interest group theory have not gained much traction. This is primarily a function of previous commentators' inability to solve two difficult and related problems: (1) development of a consensus normative framework in which to apply interest group theory; and (2) development of a meaningful, objective, and workable approach to measuring interest group dynamics in the real world. The article offers solutions to both.

The article first proposes workably competitive pluralism as a norm to which the regulatory process should aspire in …

A Guide To Training Therapists In Dealing With Difficult Patient Care Situations, Tegan Aymond, Andrea Kuhn

Occupational Therapy Capstones

A literature review was conducted on the difficult issues faced in occupational therapy to gain general information on how these issues and situations were being addressed. After reviewing the literature, it was noted that there is a high rate of over-involvement when working in occupational therapy that can lead to stress and burnout. It was found that defining the role of occupational therapy is difficult and trying to establish boundaries within that role is a constant challenge. The lack of knowledge on issues such as ethics, therapeutic relationship, and core values can be difficult when establishing a personal and professional …

An Occupational Therapy Guide For Entry-Level Therapists Not Specializing In The Treatment Of Upper Extremity Dysfunction: Three Common Cumulative Trauma Injuries, Ryan Edwards

Occupational Therapy Capstones

According to Kasch, Greenberg, and Muenzen (2003), occupational therapists (OTs) who are initiating entry into upper extremity orthopaedic therapy specialization do not have the knowledge and skills of experienced therapists; a concerning viewpoint considering the fairly high rate of cumulative trauma injuries each year in the United States. Carpal metacarpal osteoarthritis occurs in “approximately 8% of all adults” (Hunter, Schneider, Mackin & Callahan, 1990, p. 886), whereas ulnar neuropathy at the elbow occurs in “10 to 15 percent of adults” (Trumble, 2000, p. 327). “Tennis elbow occurs in approximately one third of the tennis population because of the requirements of …

Educational Class For Parents Of A Child Recently Diagnosed With Autism, Sarah Haugen, Marcie Sandeen

Occupational Therapy Capstones

The purpose of this scholarly project was to develop an education class for parents of children with autism. When discussing the term autism with parents it can lead to confusion, the term autism has changed greatly in the past few decades and today agreement on what the term means is still lacking. With a diagnosis of autism the parents are also going to face many challenges and added stress throughout their daily lives. These known problems helped to determine the need to create the product of this scholarly project. A review of literature and research was conducted to collect accurate …

The Impact Of Domestic Violence On Children: Implications For Professionals, Kelly Hughes, Brooke Kohler

Occupational Therapy Capstones

There are 3 million child abuse and neglect accounts reported to child welfare agencies across the United States every year, but researchers predict as many as 10 million children are exposed to domestic violence in the home (Christian, 2002). Children do not always show the physical signs of living in homes with domestic violence. Frequently the most prevalent impact can lie within the child’s mind, resulting in possible cognitive, emotional, and behavioral effects (Tri-State Rural Collaboration Project, n.d.). In order to provide the best possible care, it is imperative for professionals to understand the effects that domestic violence has on …

Home Modifications For The Elderly, Jennifer Samuelson, Kristyn Kurpius

Occupational Therapy Capstones

Purpose: The purpose of this project was to identify and present methods to increase a person’s ability to participate in occupations within their home. “Almost 50 million Americans - about one in five - live with a mental or physical disability, many of their homes are inconvenient, restrictive, or dangerous for them,” (McCullagh, 2006, p.54). As a result they are unable to participate in safe and functional occupations.

Methods: A literature review was conducted with the use of Pub Med, AJOT, textbooks, home modification handbooks, and the internet. The literature review determined the need for home modifications with the elderly …

Helping To Win The Battle Within: An Occupational Therapy Perspective On Returning War Veterans With Ptsd And Employment, Christine Avikainen, Amber L. Harvey

Occupational Therapy Capstones

Approximately 300,000 individuals of the 1.64million servive members and veterans, from Operation Iraqi Freedom/Operation Enduring Freedom have been diagnosed with post traumatic stress disorder (PTSD) (Tanielian & Jaycox, 2008).

This scholarly project has addressed the needs of the increasing number of war veterans suffering from PTSD. The soldiers returning from the present war and their employers do not have adequate resources to understand symptoms related to PTSD and the effects on functioning.

A review of the literature revealed a lack of information for returning military personnel and the process of obtaining/reobtaining employment. The research provided evidence that employers and employees …

Bright Beginnings: Quick Tips For Occupational Therapists In The Level Ii Nursery, Lindsey Bartholomew, Lacey Gramstad

Occupational Therapy Capstones

In 2004 there were 790 infants born prematurely in Wyoming (Freudenthal, 2006). Currently, the highest level of infant care available in Wyoming is a Level II nursery. In Wyoming, infants born prematurely with special medical needs are typically transported to specialized NICU's in surrounding states. The limited contact that medical staff, including occupational therapists (OT's), in rural facilities have with critically or moderately ill infants creates a lack of competency with the unique medical care needs of the infants. According to Gordon (2003) "nearly half of America's babies start out their lives in a rural community" (p. 3). Furthermore, research …

Occupational Therapy Caregiver's Guide To Spinal Cord Injury, Kelsey Berg, Amanda Larson

Occupational Therapy Capstones

In 2006, it was estimated that there were 253,000 Americans living with spinal cord injuries (SCI) (Spinal Cord Injury Information Network, 2003, p. 1). Current literature suggests that individuals are transitioning into the community earlier with the majority of care being provided by informal caregivers (Boschen, Tonack, & Gargaro, 2005). These caregivers are often unprepared for the major role they will be assuming in the care of their loved one and often their health and well-being is compromised due to the overwhelming nature of caregiving.

A comprehensive literature review was conducted to explore and identify the needs of caregivers. Topics …

Occupational Therapy Perspective In The Management Of Lymphedema, Mellonna Beckermann

Occupational Therapy Capstones

Problem: Lymphedema is a collection of excess water, interstitial fluid, plasma proteins, bacteria, and cellular waste products in the interstitial tissues as a result of an impaired lymphatic system due to disease or trauma (Cheville, McGarvey, Petrek, Russo, Taylor, & Thiadens, 2003). This fluid typically collects in a person's upper and/or lower extremities. Lymphedema is a chronic condition and can be progressive if not managed properly. Lymphedema may result in significant impairments to the person, which results in functional limitations and a decrease in quality of life (Konecne & Perdoma, 2004). Treatment of lymphedema can be costly, timely, and overwhelming …

A Wellness Program For Adults With Developmental Disabilities, Kristina Bouley, Lynsey Schirado

Occupational Therapy Capstones

When researching wellness programs for adults with developmental disabilities, the authors found there to be several barriers to wellness for this population, with one of these barriers being physical activity. Many adults with developmental disabilities do not engage in adequate amounts of physical activity (Havercamp, Scandlin, and Roth, 2004). This may be impart to inadequate access to transportation to get to and from the fitness facility (Heller, Hsieh, & Rimmer, 2004; U.S. Public Health Service, 2001), the cost of joining a fitness facility program (Heller, Hsieh, & Rimmer, 2004; Temple & Walkley, 2007), or challenges in accessing fitness equipment (Heller, …
