The Role Of Defense Mechanisms Of Israeli Society In Relationship To The Israeli–Palestinian Conflict: From “1948 Repression” To Artistic Sublimation, Keren Shechter

Expressive Therapies Dissertations

Although many researchers have examined the concept of defense mechanisms, almost none have done so from a societal and cultural point of view. The author investigated the following research questions: (1) Which defense mechanisms are used in Israeli society within the context of the Israeli–Palestinian conflict? What changes, if any, have occurred in these defenses over the years? (2) What are the reasons for the use of these defenses? What are the consequences of the use? (3) How can a transition(s) from the use of a lower-level defense mechanism(s) to a higher-level one(s) occur? What is the role of the …

Function-­Preserving Filters For Sampling In Biological Networks, Kathryn Dempsey Cooper, Sanjukta Bhowmick, Hesham Ali

Interdisciplinary Informatics Faculty Publications

Assays created to study systems of disease and aging can offer a whole new set of therapeutic targets. However, with experiments of this immense volume, data becomes unmanageable for many traditional analyses. Enter the biological network, a tool for modeling relationships among high-throughput data that is quickly rising in popularity. Small networks (in the order of hundreds to few thousands of nodes) use relationships between network structure to infer biological function; this relationship has been confirmed and used in many studies to advance the study of model organisms. Networks built for assessing entire genomes, or entire protein repertoires, however, tend …

Role Of The Immune System And Bioactive Lipids In Trafficking Bone Marrow-Derived Stem Cells In Patients With Ischemic Heart Disease, Ahmed Abdel-Latif

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Acute myocardial infarction (AMI) triggers the mobilization of stem/progenitor cells from bone marrow (BMSPCs) into peripheral blood (PB). The underlying mechanisms orchestrating this mobilization and subsequent homing of BMSPCs to the myocardium are poorly understood. While the role of traditional chemokines in the mobilization and homing of hematopoietic stem cell (HSCs) to BM niches is undisputed, their role in directing BMSPCs to the highly proteolytic environment of the ischemic myocardium is debatable and other redundant mechanism may exist. Based on our observation that bioactive lipids, such as sphingosine-1 phosphate (S1P) and ceramide-1 phosphate (C1P), play an important role in regulating …

Disruptions In The Regulation Of Extracellular Glutamate In The Rat Central Nervous System After Diffuse Brain Injury, Jason Michael Hinzman

Theses and Dissertations--Neuroscience

Glutamate, the predominant excitatory neurotransmitter in the central nervous system, is involved in almost all aspects of neurological function including cognition, motor function, memory, learning, decision making, and neuronal plasticity. For normal neurological function, glutamate signaling must be properly regulated. Disrupted glutamate regulation plays a pivotal role in the acute pathophysiology of traumatic brain injury (TBI), disrupting neuronal signaling, initiating secondary injury cascades, and producing excitotoxicity. Increases in extracellular glutamate have been correlated with unfavorable outcomes in TBI survivors, emphasizing the importance of glutamate regulation.

The aim of this thesis was to examine disruptions in the regulation of extracellular glutamate …

Regulation Of Hepatic Gene Expression During Liver Development And Disease, Hui Ren

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

My first project was to investigate the role of Hepatocyte Nuclear Factor 1 (HNF1) and Nuclear Factor I (NFI) on alpha-fetoprotein (AFP) promoter activity during liver development. AFP is highly expressed in the fetal liver, silenced at birth, and remains at very low levels in the adult liver. A GA substitution located at -119 of the human AFP promoter is associated with hereditary persistence of AFP (HPAFP) expression in the adult liver (Hum Molec Genet, 1993, 2:379). The -120 region harbors overlapping binding sites for HNF1 and NFI. While it has been shown that the GA substitution increases HNF1 binding, …

Blast-Induced Brain Injury: Influence Of Shockwave Components, Dexter V. Reneer

Theses and Dissertations--Neuroscience

Blast-induced traumatic brain injury (bTBI) has been described as the defining injury of Operations Enduring Freedom and Iraqi Freedom (OEF/OIF). Previously, most blast injury research has focused on the effects of blast on internal, gas filled organs due to their increased susceptibility. However, due to a change in enemy tactics combined with better armor and front-line medical care, bTBI has become one of the most common injuries due to blast. Though there has been a significant amount of research characterizing the brain injury produced by blast, a sound understanding of the contribution of each component of the shockwave to the …

Signaling Mechanisms Involved In The Generation Of Human Peripheral Itregs, Mary Catherine Reneer

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Maintaining balance in the human immune system is critical for the body’s ability to discriminate between foreign and self-antigens. This balance is achieved, in part, by a subpopulation of T cells known as induced regulatory T cells (iTregs). Dysregulation of this population may contribute to the onset and progression of cancer, chronic inflammation and autoimmune diseases. Therefore, manipulation of iTreg development holds promising therapeutic potential; however, studying this vital population has proven difficult due to low numbers, heterogeneous cell populations, substantial phenotypic differences between mouse and human cells, and the high plasticity seen in iTregs. These current limitations have prevented …

Crosstalk Between Gastrointestinal Epithelial Cells And Resident Microbiota Promotes Immune Homeostasis, Eric William Rogier

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

The gastrointestinal tract houses one of the most dense and diverse communities of bacteria on the planet. The mutualistic relationship between the host and commensal microbe permits the microbe an ideal environment to grow and provides the host with increased caloric intake, maturation of the adaptive immune system, and resistance against invading pathogens. To maintain a system in which both parties benefit, the epithelium has evolved numerous strategies to ensure epithelial cells respond to microbes appropriately and that potentially hazardous commensals remain distanced from the soma proper. Breakdown of these propitiating mechanisms elicits unchecked inflammation and can lead to pathology …

Prion Characterization Using Cell Based Approaches, Vadim Khaychuk

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Prions are the causative agents of a group of lethal, neurodegenerative conditions that include sheep scrapie, bovine spongiform encephalopathy (BSE), and human Creutzfeldt-Jakob disease (CJD). Prions are derived from the conversion of a normal, primarily alpha-helical, cellular prion protein (PrP^C), to an infectious, beta sheet-rich conformer (PrP^Sc). Many unresolved issues surround the process of PrP conversion, and we know very little about cellular responses to these unique pathogens. Our lack of knowledge relates, in part, to the difficulty of infecting cells in vitro with prions. While expression of PrP^C is an absolute requirement for prion …

A Diet Enriched In Stearic Acid Protects Against The Progression Of Type 2 Diabetes In Leptin Receptor Deficient Mice (Db/Db), Valerie Lynn Reeves

Theses and Dissertations--Physiology

Dietary saturated fat intake contributes to diabetes and cardiovascular disease, as shown in numerous animal and human studies. However, the hypothesis that stearic acid, a saturated fat, has beneficial effects on these conditions has not been adequately tested. Leptin receptor deficient mice (db/db) and wild-type mice were fed either chow or a high fat diet enriched in either stearic acid or oleic acid for ten weeks. The progression of diabetes was evaluated with blood glucose, insulin, and metabolic parameter measurements. At the conclusion of the study, pancreatic islet organization was examined, and blood, liver and feces were assayed for fatty …

C-Abl And Arg Drive Cancer Chemoresistance Via Activation Of Multiple Signaling Pathways, Jonathan Thomas Sims

Theses and Dissertations--Pharmacology and Nutritional Sciences

Despite 35 years of clinical trials, there has been little improvement in one-year survival rates with any chemotherapeutic regimen for the treatment of metastatic melanoma due to resistance to all known agents. Regardless of advances in detection and prevention, diagnosis of metastatic disease remains a death sentence. Resistance mechanisms, including aberrant kinase signaling and drug transport pumps, indicate a need for identification of other therapeutic targets that impinge upon multiple signaling pathways. The Abl family of non-receptor tyrosine kinases (c-Abl, Arg) has been indicted as a causative force in leukemia for more than three decades; however, their role in solid …

Inflammatory Interactions And Secretion In Cardiac Remodeling, Fanmuyi Yang

Theses and Dissertations--Physiology

Heart failure contributes to nearly 60,000 deaths per year in the USA and is often caused by hypertension and preceded by the development of left ventricular hypertrophy (LVH). LVH is usually accompanied by intensive interstitial and perivascular fibrosis which may contribute to arrhythmogenic sudden cardiac death. Emerging evidence indicates that LV dysfunction in patients and animal models of cardiac hypertrophy is closely associated with perivascular inflammation.

To investigate the role of perivascular inflammation in coronary artery remodeling and cardiac fibrosis during hypertrophic ventricular remodeling, we used a well-established mouse model of pressure-overload-induced LVH: transverse aortic constriction (TAC). Early perivascular inflammation …

Evaluating Retention In Medical Care And Its Impact On The Health Outcomes Of Individuals Living With Human Inmmunodeficiency Virus, Timothy N. Crawford

Theses and Dissertations--Epidemiology and Biostatistics

In the last few years, engagement in medical care among individuals living with HIV has become a major priority among HIV medical providers and public health researchers. Engagement in medical care is an important concept as it involves the process of linking newly diagnosed individuals into medical care and retaining those individuals in care throughout the course of their infection. Although there have been major advances in the management of HIV, like the advent of Highly Active Antiretroviral Therapy, morbidity and mortality due to HIV cannot be fully reduced if the individual does not optimally retain in care. Retention in …

The Relationship Of Social Stress, Economic Hardship, And Psychological Distress To Addiction Severity Among Kentucky Substance Abuse Treatment Participants, Elizabeth A. Wahler

Theses and Dissertations--Social Work

Stress is associated with poor mental health, specifically anxiety and depression, and stress and mental health problems are predictors of substance dependence and relapse. Social characteristics, such as racial/ethnic minority status, female gender, and low socioeconomic status, are often associated with increased psychological distress and substance use disorders. Pearlin’s social stress theory postulates that this association is due to increased exposure to stress and subsequent experiences of distress related to social disadvantage and decreased access to resources for coping with stress. This project uses a social stress theoretical perspective to examine predictors of substance use after treatment entry and follow-up …
