The Study Of Nitric Oxide Synthase Expression, Function, And Regulation In The Renal Vasculature During Postnatal Renal Development, Brian Blake Ratliff Apr 2006

The Study Of Nitric Oxide Synthase Expression, Function, And Regulation In The Renal Vasculature During Postnatal Renal Development, Brian Blake Ratliff

Theses and Dissertations in Biomedical Sciences

The newborn kidney is vulnerable to vasomotor acute renal failure (ARF) from adverse perinatal events or complications of prematurity. Nitric oxide (NO) vasodilation is vitally protective in this type of ARF, but its relationship with other vasoactive factors, such as angiotensin II (AII) has not been examined. In the immature kidney, nitric oxide synthase (NOS) isoforms, specifically eNOS and nNOS, are developmentally regulated, but their specific role and regulation are unknown.

The enhanced vasodilatory role of NO in the immature kidney was hypothesized to be attributed to regulatory, expressional, and functional differences in eNOS and nNOS isoforms from the adult. …

The extent of trauma was reviewed to include various studies relating to the impact trauma has on juveniles. Robert Agnew's General Strain Theory provided support for the differences that exist between males and females when it comes to trauma contributing to juvenile delinquency. Gender differences in emotional response to strain were reviewed, focusing on post-traumatic stress disorder (PTSD). The data that provided support for the …


A Framework For The Representation Of Cohesion In Small Combat Units, William Eugene Warner Apr 2006

A Framework For The Representation Of Cohesion In Small Combat Units, William Eugene Warner

Computational Modeling & Simulation Engineering Theses & Dissertations

Current combat simulations deal well with large unit formations, weapon systems, and physical effects such as attrition. Human factors such as morale, cohesion, and effects of stress are modeled much less adequately. Of the human factors affecting the psychology of a combat unit, military psychologists have identified cohesion as one of the most important. The concept of cohesion, referring to both the interpersonal relationships between soldiers in a military unit and to the morale solidarity of a military force, has been central to military analysis for many years.

A model framework has been developed that can operationalize the concept of …

The Introduction Of The Importance Of Identifying Patient Priorities Into A Care Model, Susan Loushin Mar 2006

The Introduction Of The Importance Of Identifying Patient Priorities Into A Care Model, Susan Loushin

Theses and Graduate Projects

Nursing has a long history of developing care plans that address what nurses perceive as the problems and needs of the patients under their care. One of the greatest ironies in nursing is that the most important person, the patient, is often excluded from the planning process. The importance of soliciting input from the patient or family has been diminished in recent years, but is now acknowledged to be the key to high quality individualized care. Patient and family involvement is not just about organizational structures-it is a cultural change. lt is empowering patients and their families to have a …

The Relationship Between Social Behaviors And Working Memory In School-Age Children With Language Impairment, Melanie Diane Javid

Theses and Dissertations

Children with language impairment (LI) have notable social problems (Brinton & Fujiki, 2004). Research has shown that children with LI often have deficits in working memory (Kirchner & Klatsky, 1985; Stark, Poppen, & May, 1987). The relationship between working memory and social behaviors has not been clearly defined. This study examined this relationship in children with LI and typical age-matched peers by asking participants to repeat nine nonwords and correlating these results with social behaviors as rated by teachers. The Teacher Behavior Rating Scale (TBRS; Hart and Robinson, 1996) was used to compare social behaviors of 19 school-age children with …

Analysis Of Patient Information: An Empirical Modeling Approach, Tony A. Murphy Mar 2006

Analysis Of Patient Information: An Empirical Modeling Approach, Tony A. Murphy

Theses and Dissertations

With rising costs and increasing complexities, many hospitals seek to better understand the intricate details of their operations. Increasingly, these organizations have a strong desire to accurately predict the resources required to effectively treat their patient load. This research investigates patient length-of-stay in a hospital neurological unit using an empirical modeling approach. Factors significantly affecting patient length of stay were identified and used to construct a regression model. The predictive model provides hospital decision makers with a compact tool to input what-if scenarios and predict future patient treatment lengths, thus, allowing the hospital to properly allocate resources.


Contemplating A New Model For Air Force Aerospace Medical Technician Skills Sustainment Training, Robert M. Corrigan Mar 2006

Contemplating A New Model For Air Force Aerospace Medical Technician Skills Sustainment Training, Robert M. Corrigan

Theses and Dissertations

Two decades ago, Aerospace Medical Technicians received robust skills sustainment training through exposure to multifaceted patient treatment environments. Available training environments included inpatient care, outpatient care, and emergency services. This diverse training environment made possible through large operating budgets and an extraordinary infrastructure could not last. Today (after five separate base closure and realignment initiatives), medical funding and infrastructure is but a shadow of what it once was. Budget constraints and the rising cost of healthcare have necessitated a purposeful movement away from inpatient and emergency care, toward outpatient and preventative medicine. Although changes in Air Force health care delivery …

The Zucker Rat As A Model Of Obesity-Hypertension, Ryan Morrison Jan 2006

The Zucker Rat As A Model Of Obesity-Hypertension, Ryan Morrison

Theses, Dissertations and Capstones

Hypertension is a serious health problem that affects approximately 1 in 4 American adults. Most cases are diagnosed as essential hypertension, meaning that the exact cause is unknown. In most patients, however, excess weight is a major contributory factor to the development of essential hypertension. The role of obesity in promoting hypertension is now well documented and has become the foundation for an entire field of research known alternately as obesity-hypertension, obesity-induced hypertension, or obesity-associated hypertension. In this field, rapid advances are being made in our understanding of how obesity and hypertension are linked. A plethora of related risk factors, …


A Mechanistic Study Of The Protective Effects Of S-Adenosyl-L-Methionine Against Hepatotoxicity Of Acetaminophen, Marcus V. Terneus Jr. Jan 2006

A Mechanistic Study Of The Protective Effects Of S-Adenosyl-L-Methionine Against Hepatotoxicity Of Acetaminophen, Marcus V. Terneus Jr.

Theses, Dissertations and Capstones

Hepatic toxicity is known to be associated with excessive doses of the over-the-counter analgesic, acetaminophen (APAP). APAP overdose is the leading cause of drug-induced liver failure in the United States. APAP hepatotoxicity is dependent on the biotransformation of APAP by cytochrome P450 to the toxic metabolite, N-acetyl-p-benzoquinone imine (NAPQI). APAP, when taken in excessive doses, can lead to severe liver damage with the potential to progress to liver failure. Despite substantial efforts in past studies, the mechanism by which APAP induces such damaging effects is not completely understood. Recent discoveries suggest that glutathione (GSH) depletion, protein alkylation and reactive metabolite …


Protein Kinase C Activity In Mouse Eggs Regulates Gamete Membrane Interaction, Hiroto Akabane Jan 2006

Protein Kinase C Activity In Mouse Eggs Regulates Gamete Membrane Interaction, Hiroto Akabane

Theses, Dissertations and Capstones

Every mammalian life develops from one cell after fertilization of an egg by the sperm. The molecular pathways governing this event are still poorly understood. Numerous reports indicate that mammalian eggs highly express various protein kinase C (PKC) isoforms. Accordingly, we hypothesize that PKC activity in the egg plays an important role during egg-sperm membrane binding and fusion. In this study, we tested our hypothesis in mouse gametes using two types of PKC inhibitors (calphostin c and staurosporine) and the typical PKC activator, phorbol ester 12-tetradecanoylphorbol-13 acetate (PMA). After treatment with the individual drug, eggs were inseminated with sperm. The …


Thimerosal-Induced Neuritoxicity: Apoptosis Occurs Through A Mitochondrial-Mediated Pathway Via The Jnk Signaling Pathway, Michelle L. Herdman Jan 2006

Thimerosal-Induced Neuritoxicity: Apoptosis Occurs Through A Mitochondrial-Mediated Pathway Via The Jnk Signaling Pathway, Michelle L. Herdman

Theses, Dissertations and Capstones

Thimerosal is an organic mercurial containing an ethylmercury moiety attached to the sulfur atom of thiosalicylate. Since the 1930s, thimerosal has been used as an antiseptic and a preservative in a wide variety of products, including medicinal preparations administered to children and pregnant women. Past exposures to mercurials have indicated that mercury is a neurotoxin, and can also affect the kidney, skin, eyes, and immune system. Additionally, fetuses exposed to mercurials are more susceptible to toxicity because the nervous system is continuously developing. However, despite its widespread use, thimerosal was only studied on a limited basis until the end of …


Regulation Of Biofilm Formation Of Pseudomonas Aeruginosa, Nathaniel Edwards Head Jan 2006

Regulation Of Biofilm Formation Of Pseudomonas Aeruginosa, Nathaniel Edwards Head

Theses, Dissertations and Capstones

Cystic fibrosis (CF) is the most common, autosomal recessive lethal genetic disease in the Caucasian population, resulting from a malfunctioned cystic fibrosis transmembrane conductance regulator (CFTR) and leading to bacterial lung infections. P. aeruginosa, an opportunistic pathogen, establishes a chronic infection in CF with a phenotype of overproduction of an exopolysaccharide (alginate) due to host-directed mutagenesis. While free-floating planktonic bacteria can be properly cleared from the CF lung, P. aeruginosa, along with alginate production, establishes an infection in the form of a biofilm which supports its survival in nature and in vivo. As a result, genomic structure, …


Characterization Of The Dna-Binding Properties Of Silent Information Regulator 3 Protein, Cotteka Nichisha Johnson Jan 2006

Characterization Of The Dna-Binding Properties Of Silent Information Regulator 3 Protein, Cotteka Nichisha Johnson

Theses, Dissertations and Capstones

The eukaryotic genome is organized into distinct domains with discrete regulatory potential, influenced by the variation in local chromatin structure. An example of chromatin-mediated consequences on gene expression is mating type determination of yeast Saccharomyces cerevisiae, which depends on silencing of specific gene cassettes. Silencing in yeast involves key proteins, amongst which the Silent Information Regulator (Sir) proteins are essential. Sir1p, Sir2p, and Sir4p are recruited to nucleate silencing events, while Sir3p serves as the pivotal factor in spreading the silent state. This investigation characterizes the DNA binding properties of Sir3p using DNA fragments with varying degrees of inherent flexibility, …
