Differential Effects Of Endocannabinoid Catabolic Inhibitors On Opioid Withdrawal In Mice, Thomas Gamage Dec 2013

Differential Effects Of Endocannabinoid Catabolic Inhibitors On Opioid Withdrawal In Mice, Thomas Gamage

Theses and Dissertations

The effects of cannabinoids in reducing somatic signs of opioid withdrawal have been known for some time. In morphine dependent rodents, opioid withdrawal following precipitation with the mu opioid antagonist naloxone elicits robust withdrawal behaviors including jumps, paw flutters, head shakes, diarrhea and weight loss. Delta-9-tetrahydrocannabinol has been shown to reduce this opioid withdrawal in mice via activation of the cannabinoid type-1 (CB1) receptor and recently it has been shown that inhibition of the catabolic enzymes for endocannabinoids also reduce somatic signs of opioid withdrawal. Specifically, inhibition the enzyme fatty acid amide hydrolase (FAAH), the catabolic enzyme for the endocannabinoid …

Tobramycin Disposition In The Lung Following Airway Administration, Min Li Dec 2013

Tobramycin Disposition In The Lung Following Airway Administration, Min Li

Theses and Dissertations

Tobramycin disposition following airway administration was evaluated by meta-analysis of human data in the literature and, experimentally, using a realistic ex vivo model, the isolated perfused rat lung preparation (IPRL). Pulmonary bioavailability of inhaled tobramycin in published studies was re-evaluated separately for CF and healthy adults, with the drug’s intrinsic pharmacokinetic (PK) parameters obtained from intravenous (IV) studies in the literature. While large variations in tobramycin’s clearance precluded accurate assessment of its bioavailability, the results were indicative of substantial pulmonary absorption, in spite of its hydrophilic and poly cationic properties. To explore its disposition kinetics and mechanisms following airway administration, …


Transcriptional Crosstalk Between Helper Bacteriophages And Staphylococcal Aureus Pathogenicity Islands, Kristin Lane Dec 2013

Transcriptional Crosstalk Between Helper Bacteriophages And Staphylococcal Aureus Pathogenicity Islands, Kristin Lane

Theses and Dissertations

Acquisition of a superantigen pathogenicity island (SaPI) significantly increases virulence in Staphylococcus aureus. Horizontal transfer of SaPIs occurs at high frequency and depends upon a helper bacteriophage, either through direct infection or SOS-mediated induction of a lysogen. SaPIs hijack the packaging machinery of the helper phage, leading to the formation of SaPI-containing transducing particles that can introduce the pathogenicity island into neighboring SaPI-negative cells. All SaPIs contain a conserved core of genes, some of which are co-transcribed as an operon and encode functions involved in helper exploitation. The goal of this study was to more fully understand the intricate relationships …

Transcending Microbial Source Tracking Techniques Across Geographic Borders: An Examination Of Human And Animal Microbiomes And The Integration Of Molecular Approaches In Pathogen Surveillance In Brazil And The United States, Amber Mae Koskey

Theses and Dissertations

Waterborne illnesses, attributed to the ingestion or contact with contaminated water, present a significant global health concern. Surface water sources can be impacted by wide array of pollution inputs, but fecal pollution generates the most significant and acute threat to human health. Therefore, the detection of fecal bacteria in surface water sources remains an important public health objective. Current surface water monitoring employs the use of fecal indicator bacteria (FIB) including E. coli and enterococci as proxies for pathogenic organisms carried in fecal pollution. These traditional indicators, detected by culture-based microbiological methods, do not discriminate fecal sources from another. New …

Representing And Retrieving Patients' Falls Risk Factors And Risk For Falls Among Adults In Acute Care Through The Electronic Health Record, Jann Pfaff

Theses and Dissertations

Defining fall risk factors and predicting fall risk status among patients in acute care has been a topic of research for decades. With increasing pressure on hospitals to provide quality care and prevent hospital-acquired conditions, the search for effective fall prevention interventions continues. Hundreds of risk factors for falls in acute care have been described in the literature. However, due to variations in the terms utilized to represent each fall risk factor, an effort to compare findings across settings and replicate research is hampered. As the expectations for the effective use of electronic health records increase, an opportunity exists to …


The Experiences Of Women Entering Methadone Treatment For Opioid Use: An Interpretive Phenomenological Inquiry, Melissa Mae Rubio Dec 2013

The Experiences Of Women Entering Methadone Treatment For Opioid Use: An Interpretive Phenomenological Inquiry, Melissa Mae Rubio

Theses and Dissertations

The United States is facing a momentous public health problem of prescription and illicit opioid use among women. Traditionally in health literature women have received less attention than men and this is especially true with regard to drug use. In terms of recovery from opioid use, treatment centers that use methadone as a pharmaceutical replacement for illicit opioids have been present in the US for decades, and women have been enrolling in treatment since its inception. However, there is little in the literature about the characteristics of these women, why they choose methadone treatment, and what their experiences are while …

New Graduate Nurses' Experiences Of Transition During Orientation Into Critical Care, Mari Beth St Clair Dec 2013

New Graduate Nurses' Experiences Of Transition During Orientation Into Critical Care, Mari Beth St Clair

Theses and Dissertations

The concept of new graduate nurses working in critical care for some healthcare systems remains a fairly new concept. Often new graduate nurses begin their orientation in critical care with minimal to no critical care experience. Orientation for the new graduate nurses can be challenging as for years new graduate nurses were not allowed to work in critical care until they had a minimum of one year of nursing experience. Currently new graduate nurses beginning employment in critical care are faced with revisiting basic nursing and learning critical care nursing at the same time. In order for critical care units …


Simulation Design Characteristics: Perspectives Held By Nurse Educators And Nursing Students, Jane Brekke Paige Dec 2013

Simulation Design Characteristics: Perspectives Held By Nurse Educators And Nursing Students, Jane Brekke Paige

Theses and Dissertations

Simulation based learning (SBL) is pedagogical method poised to innovate nursing educational approaches. Yet, despite a growing body of research into SBL, limited investigation exists regarding assumptions and beliefs that underpin SBL pedagogy. Even though key simulation design characteristics exist, the particular methods nurse educators use to operationalize simulation design characteristics and how these choices are viewed from the perspective of nursing students is unknown. Without understanding what motivates educators to design simulations as they do, it is difficult to interpret the evidence that exists to support chosen methods. Through the exploration of perspectives (points-of-view), underlying beliefs can be uncovered. …

The main aim of the current study is to assess if a relationship exists between self-selected coping styles and levels of perseverative cognition (PC). Recent pilot studies have revealed a relative distinction between the coping styles people choose when coping with stress, i.e., those that are physically active (PAC) like going for a walk, jogging, or lifting weights, and those that are physically passive (PPC) like reading …


The Influence Of Position Type And Generational Grouping On Job Satisfaction Of Milwaukee County's Public Health Workforce, Jeanette L. Kowalik Dec 2013

The Influence Of Position Type And Generational Grouping On Job Satisfaction Of Milwaukee County's Public Health Workforce, Jeanette L. Kowalik

Theses and Dissertations

Nationally, the public health workforce (PHW) consists of 155,000 staff (NACCHO, 2010). It is projected that half of the PHW will soon retire. Health departments must find ways to retain its diverse workforce.

Job Satisfaction is a critical variable that impacts a sustained PHW. Job Satisfaction assessments can promote sustainability of the workforce because the data assembled from the assessments can inform research, policy, and practice. Public health workers that report high Job Satisfaction are less likely to quit as well as delay retirement (RWJF, 2013).

The purpose of this study is to examine the influence of position type and …

by

Athena Baranowski

The University of Wisconsin–Milwaukee, 2013

Under the Supervision of Dr. Alexander Arnold

The vitamin D receptor (VDR) is a ligand–dependent transcription factor, which belongs to the nuclear receptor superfamily. VDR–mediated gene regulation is governed by coregulators (coactivators and corepressors). VDR coregulator binding inhibitors (CBIs), which were discovered using high throughput screening (HTS), were evaluated using cell–based assays and biochemical assays to determine their ability to inhibit the interaction between VDR and steroid receptor coactivator–2 (SRC–2). Determining their ability to inhibit the VDR–SRC–2 interaction can lead to the …

Modulation Of Interleukin-17 By Tumor Necrosis Factor Alpha During The Immune Response To Borrelia Burgdorferi, Velinka Medic

Theses and Dissertations

Arthritis is one of the main complications of late-stage Lyme borreliosis. Cytokines play an important role in the persistent inflammation that is elicited by the causative agent of disease, Borrelia burgdorferi. Tumor necrosis factor alpha (TNF-alpha) is a pro-inflammatory cytokine that is induced by B. burgdorferi and that has been implicated in development of arthritis. However, in a mouse model of Lyme arthritis, treatment with anti-TNF-alpha; antibodies increased the severity of disease. By contrast, injection of recombinant TNF-alpha; ameliorated arthritis in this model. These findings suggested that other factors might be involved during the development of Lyme arthritis. One possible …


Life After Adhesion: L-Selectin Throughout The T Cell Lifespan, Abner Garcia Fernandez Dec 2013

Life After Adhesion: L-Selectin Throughout The T Cell Lifespan, Abner Garcia Fernandez

Theses and Dissertations

Lymphocytes require antigenic encounter to activate and proliferate, eventually clearing the source of antigenic challenge. The peripheral lymph nodes (PLN) are the primary sites of antigenic encounter and thus the ability of lymphocytes to migrate to this tissue is a requirement for mounting effective immune responses. The process of lymphocyte migration to the PLN is known as the "adhesion cascade". Specifically, lymphocytes are captured from the blood through the adhesion molecule, L-selectin, followed by CC chemokine receptor 7 (CCR7)-mediated integrin activation, which ultimately results in cell transmigration into the PLN. Because the PLN is the site where antigenic encounter is …

Brain Mapping Of The Mismatch Negativity Response To Vowel Variances Of Natural And Synthetic Phonemes, Lyndsy Marie Smith

Theses and Dissertations

The mismatch negativity (MMN) is a specific event-related potential (ERP) component used frequently in the observation of auditory processing. The MMN is elicited by a deviant stimulus randomly presented in the presence of repeating stimuli. The current study utilized the MMN response in order to determine the temporal (timing) and linguistic processing of natural and synthetic vowel stimuli. It was hypothesized that a significant MMN response would be elicited by natural and synthetic vowel stimuli. Brain mapping of the MMN response was hypothesized to yield temporal resolution information, which would provide detail regarding the sequential processing differences between natural and …


Analysis Of Plasminogen Binding To Treponema Denticola, A Key Periopathogen, Brittney Tegels Nov 2013

Analysis Of Plasminogen Binding To Treponema Denticola, A Key Periopathogen, Brittney Tegels

Theses and Dissertations

Periodontitis is a chronic inflammatory disease that affects over 116 million adults in the United States. A shift in the normal microflora occurs as periodontal disease develops resulting in a larger number of Gram-negative anaerobes and spirochetes. An increase in the oral spirochete, Treponema denticola, is highly correlated with periodontal disease progression and severity. The ability of this periopathogen to thrive in the subgingival crevice is dependent on complement evasion mechanisms. Earlier analyses demonstrated that the primary mechanism of T. denticola serum resistance is binding of the human complement regulatory protein, Factor H (FH), to the factor H-binding protein (FhbB). …


Sirt6 And Premature Aging Of Hutchinson-Gilford Progeria Syndrome Fibroblasts., Helal Endisha Nov 2013

Sirt6 And Premature Aging Of Hutchinson-Gilford Progeria Syndrome Fibroblasts., Helal Endisha

Theses and Dissertations

The genetic disease Hutchinson-Gilford Progeria Syndrome (HGPS) arises from a de novo single nucleotide mutation (1824CàT) in the LMNA gene. As a result, the mutated lamin A protein (progerin) remains farnesylated and permanently attached to the nuclear membrane. Progerin accumulates and deforms the nuclear membrane leading to an array of cellular abnormalities driving the cells to enter a state of permanent cell-cycle arrest early on in replicative age i.e. premature cellular senescence. Cellular senescence has been extensively studied as one of the contributing factors to aging in HGPS patients and other age-related diseases. There has also been evidence to show …
