Can Antibiotics From Recently Discovered Marine Actinobacteria Slow The Tide Of Antibiotic Resistance?, Lorraine Susan Tangeman

Browse all Theses and Dissertations

Actinobacteria, one phylum of gram positive bacteria, are found throughout all the environments on earth. Actinobacteria have long been studied for the benefits they provide, both to their environment and to humans, and have a great capacity for adaptation and evolution. They decompose organic matter, replenishing nutrients into the soil, and as such are important members of the food chain. Humans benefit from the exploitation of Actinobacterial metabolites as antimicrobial drugs. These antimicrobials have been effectively utilized for decades in the fight against infectious disease. Despite the success of this drug arsenal we are now in the midst of an …

Novel Approaches For The Eradication Of Hiv Latently Infected Cells, Sally Al Ali

Browse all Theses and Dissertations

The development of a suitable experimental cell model to study HIV latency in primary cells could have a massive effect on the current approaches to eradicate virus in latently infected cells. The main proposal of this paper is to develop an in vitro HIV cell model that represents HIV latency in vivo, then to create a more effective viral vector in order to target HIV reservoirs. For this goal, a directed evolution method is suggested to be used in order to mutate the AAV cap gene to generate a recombinant AAV vector that is capable of infecting primary resting CD4+ …

Conversion Of The U937 Monocyte Into "Macrophage-Like" Populations Exhibiting M1 Or M2 Characteristics, Bradley M. Sharp

Browse all Theses and Dissertations

The U937 cell line is an oncogenic human monocyte cell line. These monocytes have the potential of differentiating into either macrophages or dendritic cells (Lawrence et al., 2011). This differentiation pattern depends on the characteristics of the tissue microenvironment (Kigerl et al., 2009). PMA (Phorbol 12-Myristate 13-Acetate) is a phorbol ester capable of transforming monocytic cells toward the macrophage pathway. Upon treatment with PMA, U937 cells under-go a series of morphological and functional changes. Traditionally monocytic cell lines are used as a model of macrophage function, because current human macrophage cell lines require a T-cell conditioned growth medium and contact …

Hpai H5n1: A Global Pandemic Concern, With Implications For Pandemic Preperation And Public Health Policy, Lauren M. Koontz

Browse all Theses and Dissertations

Research on highly pathogenic avian influenza A (HPAI) H5N1 has gained much attention in recent years due to its devastating impact within the bird population. While transmission to humans is rare, infections are fatal in more than half of the cases. One of the main concerns among the scientific community is the ability for this virus to mutate in a way much like seasonal influeanza that would allow it to be transmitted efficiently among the human population. Two researchers were able to separately create mutant isolates of H5N1 influenza A virus that could be transmitted via the respiratory route between …

In an effort to better understand the ancestral state of the human distal gut microbiome, we examine feces retrieved from archaeological contexts (coprolites). To accomplish this, we pyrosequenced the 16S rDNA V3 region from duplicate coprolite samples recovered from three archaeological sites, each representing a different depositional environment: Hinds Cave (~8000 years B.P.) in the southern United States, Caserones (1600 years B.P.) in northern Chile, and Rio Zape in northern Mexico (1400 years B.P.). Clustering algorithms grouped samples from the same site. Phyletic representation was more similar within sites than between them. A Bayesian approach to source-tracking was used to …

Situation Analysis Of Somalia’S 2011 Famine, Ahmed Mohamed Askar

Master of Public Health Program Student Publications

This CE examined the contributing factors of famine in Somalia and developed a situation analysis of Somalia’s 2011 famine. The situational analysis was developed using health and famine indicators. Data from geographic information system (GIS) was also used to supplement analysis to look for trends and patterns of the famine. I predicted that conflict was the leading factor in Somalia’s 2011 famine. I concluded that conflict exacerbated the famine situation in the south of Somalia but in the north (Somaliland) famine was due to climate and lack of permanent rivers and water sources.

Foodborne Illness Outbreak Response: A Snapshot Of Ohio, Calen Wherry

Master of Public Health Program Student Publications

Biosurveillance is one of the primary roles of local Public health offices. As the all-hazards (biological, chemical, and radiation emergencies) approach adds to the responsibilities already performed in foodborne illness outbreak response, it is crucial to assess the capabilities and robustness of the local public health Foodborne Illness (FBI) response. By surveying the most populated counties in Ohio with a checklist based on the 2009 Council for Improvement of Foodborne Outbreak Response (CIFOR) guidelines, it was possible to obtain a snapshot of the current outbreak response capabilities. Though only one county reported 100% compliance with the checklist, the overall average …

Needs Assessment For The Mobile Health Clinic Of The Sukhdev Raj Soin Hospital, Luke Rothermel

Master of Public Health Program Student Publications

India has an established system of medical and public health services to provide care to all citizens through a government‐run network of providers and infrastructure. That system, though, is constrained by socio‐economic limitations, a booming population, and the cultural variations of its population. In addition to the public efforts to provide health care, the private sector has grown to serve a large portion of the population. Many of these private initiatives are found in urban areas where the potential for financial gain are great, but others have spread into semi‐urban areas and villages to serve the more rural populations. The …

The Efficacy Of Abstinence Only Education, Jennie Watt Mcadams

Master of Public Health Program Student Publications

Chlamydia, Gonorrhea and unplanned teen pregnancies cost the United States billions of dollars every year in various forms of government aid. Why are the numbers of teenage incidences of these health indicators higher than almost every other industrialized nation? Why are the youth in the United States so far behind their peers in sexual health? This paper proposes that one cause is that government funding goes to abstinence only education curriculum which is taught in many schools across the nation. These curricula many times do not teach youth about sexual protection or health and other times contain false information. If …

Lipase-Kinase Associations Involving Pld2, Jak3 And Fes That Underlie Cancer Cell Proliferation And Invasion, Qing Ye

Browse all Theses and Dissertations

Phospholipase D (PLD) is an enzyme that breaks down phospholipids in the cell membrane. It has been suggested that PLD may play a role during cell proliferation and cell invasion of cancer cells. The objective of this thesis was to define new molecular signaling pathways in which PLD2 might be involved in terms of cell proliferation (first part) and cell invasion (second part). To this, I compared molecular and biochemical aspects between untransformed cell lines with highly invasive, transformed breast cancer cells. In the first part, I investigated the interaction of two tyrosine kinases with PLD2 and the effect of …

Elucidating Transcription Factor Regulation By Tcdd Within The Hs1,2 Enhancer, Sharon D. Ochs

Browse all Theses and Dissertations

Immunoglobulin heavy chain (IgH) expression and Ig secretion is inhibited by the environmental contaminant 2,3,7,8-tetrachlorodibenzo-ρ-dioxin (TCDD). Within the IgH gene, the 3' IgH regulatory region (3'IgH RR) has been identified as a transcriptional target of TCDD. The 3'IgH RR, which in part regulates transcription of the IgH gene, is composed of four enhancers in the mouse: hs3a; hs1,2; h3b; hs4 and three enhancers in the human: hs3a; hs1,2; hs4. In humans the hs1,2 enhancer has an invariant sequence (IS) containing a DRE, NF-κB, NF1 and AP-1 binding site. Also, the enhancer has an AP1.ETS and Oct …

Establishment Of A Quiescent Infection Of Hsv-1 In L929 Fibroblasts Using A Mitotic Inhibitor And Ifn-Γ, Neelam V. Shinde

Browse all Theses and Dissertations

The goal for this study was to determine if a quiescent infection of HSV-1 could be induced in murine fibroblasts L929 by treating them with the anti-mitotic agent 5-fluoro 2'deoxy uridine (FUDR) alone and with interferon-γ. Since neurons are post-mitotic and exhibit a lower metabolic rate than other cells, fibroblasts were treated with FUDR to induce a post-mitotic state. The cell cycle arrest of fibroblasts would decrease the thymidylate metabolism and impair HSV-1 replication. An evaluation of cytopathic effects of FUDR was used to determine the optimal concentration which arrests cell growth and inhibits viral replication. Image J program developed …

Expression Of Inflamatory Response Genes In Ferrets Challenged With H5n1 Avian Influenza Virus, Brock M. Miniard

Browse all Theses and Dissertations

Influenza A H5N1 has emerged as a potential to be the next pandemic influenza. Ferrets are a promising model of H5N1 infection because the disease progression is similar to that known in humans, however reagents to characterize infections in ferrets are few. We developed real-time PCR assays for the ferret cytokines IL-1β, IL-2, IL-4, IL-8, IL-12p40, TNF-α, IFN-α, IFN-β, IFN-γ, TGFB-β1, and TGFB-β2. Forty-eight ferrets were vaccinated with either one of three vaccine formulations (Vaccine 1, Vaccine 2, or Vaccine 3), or saline (0.9% NaCl), then challenged intranasally with a lethal dose of H5N1 strain A/Vietnam/1203/04. Cytokine assays were then …

Q-Ve-Oph, A Control Caspase Inhibitor For Analyzing Neuronal Death, Rebecca L. Bricker

Browse all Theses and Dissertations

Sarin is a neurotoxin that has been used in terrorist attacks in Japan and is a potential bioterrorist weapon. It induces seizures by affecting the regulation of neurotransmitters in the brain. Seizures are directly correlated to neuronal damage. Two types of neuronal damage that can occur are apoptosis and necrosis. One of the main regions of the brain where neuronal death occurs is the hippocampus, which is involved in memory. Victims showed chronic decline of memory loss 3 and 7 years after the Tokyo's terrorist attack incident. There are treatments available that can break down sarin or can block the …

The Effects Of Enteropathogenic And Commensal Escherichia Coli On Tight Junction Permeability, Hilary Kaye Allen

Browse all Theses and Dissertations

The intestinal mucosa maintains a barrier between materials from the external environment and the internal environment of the host. Disruption of the gut wall integrity is involved in the development of various intestinal diseases, such as Irritable Bowel Syndrome (IBS) and Crohn's disease. The intestinal mucosa is lined with epithelial cells that are connected by tight junctions, the intercellular junctions that form a selectively permeable barrier between paracellular pathways. Enteric pathogens, such as enteropathogenic Escherichia coli (EPEC), can disrupt the tight junctions of epithelial cells by altering the cellular cytoskeleton or by directly affecting tight junction proteins. Commensal Escherichia coli …

Mhc Class I Expression In Murine Fibroblast And Keratinocyte Cell Lines During The First Twenty-Four Hours Of Infection With Herpes Simplex Virus-1 (Hsv-1), Prasanthi Kumchala

Browse all Theses and Dissertations

The hypothesis of this study is: HSV-1 infection of murine fibroblasts and keratinocytes inhibits expression of MHC class I molecules during first 24 hours of infection. IFN-γ pretreatment of fibroblasts protected the cells from virus-induced inhibition of MHC class I expression, but did not protect keratinocytes. Herpesviruses are known for their ability to establish persistent infections. Herpesviruses exert many different ways to suppress host defense mechanisms. One such way is by down regulating expression of the major histocompatibility complex I (MHC I) molecules in infected cells. Epidermal cells such as keratinocytes are the major sites for herpes simplex virus type …
