Temperatures Of Storage Areas In Large Animal Veterinary Practice Vehicles In The Summer And Comparison With Drug Manufacturers’ Storage Recommendations, Jeff D. Ondrak, Meredyth L. Jones, Virginia R. Fajt

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Large animal veterinarians carry drugs in their practice vehicles in storage areas that are not typically refrigerated. The most common upper limits of manufacturers’ storage temperatures for United States (U.S.)-approved non-refrigerated drugs are 25 or 30 °C. Because ambient temperatures in many locations in the U.S. exceed these temperatures during the summer, we measured storage area temperatures over 4 months in the summer of 2013 to evaluate the extent to which labeled storage temperatures are exceeded.

Methods: A convenience sample of 12 vehicles from 5 central Texas practices and 12 vehicles from 4 south central Nebraska practices was …

Whole-Genome Sequencing Of Kaposi’S Sarcoma-Associated Herpesvirus From Zambian Kaposi’S Sarcoma Biopsy Specimens Reveals Unique Viral Diversity, Landon Olp, Adrien Jeanniard, Clemence Marimo, Charles Wood

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent for Kaposi’s sarcoma (KS). Both KSHV and KS are endemic in sub-Saharan Africa where approximately 84% of global KS cases occur. Nevertheless, whole-genome sequencing of KSHV has only been completed using isolates from Western countries—where KS is not endemic. The lack of whole-genome KSHV sequence data from the most clinically important geographical region, sub-Saharan Africa, represents an important gap since it remains unclear whether genomic diversity has a role on KSHV pathogenesis. We hypothesized that distinct KSHV genotypes might be present in sub-Saharan Africa compared to Western countries. Using a KSHV-targeted enrichment …

Nebraska Center for Virology: Faculty Publications

The Liangshan prefecture in Sichuan province is an area in China severely affected by the HIV epidemic, with intravenous drug use (IDU) as the main risk factor. No reports on HIV subtypes prevalent in IDUs in Liangshan prefecture could be found. In this study, we have characterized the genotypes of HIV-1 in the IDU population in Liangshan prefecture and further determined the phylogenetic relationship of the CRF07_BC strains to HIV-1 sequences from the other regions of China, including Xinjiang and Yunnan provinces, to explore the pattern and possible diffusion pathway of HIV-1 in these regions. HIV-1-seropositive drug-naive IDUs identified in …

Discovery Of Alternative Artemisinin Binding Sites In Plasmodium Falciparum Atpase-6, Shuneize Elizabeth Slater

Electronic Theses and Dissertations

Malaria is a fatal yet preventable and treatable disease. It is commonly spread through the bite of an infected Anopheles mosquito. Malaria parasites belong to the Plasmodium genus and can be caused by the falciparum, malariae, ovale, vivax, and knowlesi species. Artemisinin is an endoperoxide lactone extracted from qinghaosu (Artemisia annua L. or sweet wormwood). It and its derivatives possess uncharacteristically rapid action against Plasmodium falciparum. Artemisinin is unique in its effectiveness in deadly cerebral malaria. The endoperoxide bridge is crucial for its antimalarial activity; however, how it aids in killing the parasite is unknown. While there are multiple suggested …

The Impact Of Disability: A Comparative Approach To Medical Resource Allocation In Public Health Emergencies, Katie Hanschke, Leslie E. Wolf, Wendy F. Hensel

Faculty Publications By Year

It is a matter of time before the next widespread pandemic or natural disaster hits the United States (U.S.). The international response to the 2009 H1N1 influenza stands as a cautionary tale about how prepared the world is for such an emergency. Although the pandemic fortunately proved to be less severe than initially anticipated, it nevertheless resulted in shortages of medical equipment, overburdened hospitals, and preventable patient deaths, particularly among young people.

A pandemic will inevitably lead to difficult decisions about the allocation of medical resources, such as who will have priority access to ventilators and critical care beds when …

The Influence Of Self-Reported Degree Of Masculinity/Femininity On Condom Use Among Black Men Who Have Sex With Men In The Deep South, Elizabeth D. Peeler

Theses and Dissertations

In the United States, 50,000 Americans are diagnosed with HIV each year (CDCa, 2014). The HIV/AIDS epidemic has had a particularly devastating impact on the southern U.S., especially the Deep South – Alabama, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina (Reif, Whetten, Wilson, McAllaster, Pence, Legrand, & Gong, 2014). The Deep South, while only composing of 36% of the national population, accounts for 50% of all people living with HIV/AIDS in the nation (Human Rights Watch, 2010). No other population has been hit harder than men who have sex with men (MSM; Prejean, Tang, & hall, 2013). Black MSM …

Hypomania And The Effects Of Working Memory Load On Risk-Taking, Joseph B. Todd

College of Graduate Studies: Theses & Dissertations

Hypomania is an episodic mood state that closely resembles mania, and it is characterized by irritability, euphoria, racing thoughts, and impulsivity. The present study focuses on risk-taking, a behavioral manifestation of impulsivity, and the potential working memory mechanisms responsible for eliciting this behavior in people affected by hypomanic symptoms. Specifically, research suggests that taxing working memory accelerates the process by which individuals with high levels of hypomanic symptoms engage in risk-taking. The purpose of the current study was to examine the effects on hypomanic traits and working memory taxation on a behavioral measure of risk-taking. One hundred and forty-five participants …

Remote Sensing Based Predictive Decision Support System For Assessment Of Environmental Conditions For Epidemic Cholera, Haidar Shakuir Aldaach

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cholera, a water borne diarrheal disease, is strongly associated with environmental processes. However, quantitative linkages of environmental processes with cholera and climate is still emerging. Linking diseases such as cholera with climate will aid in development of models that can predict spatial and temporal outbreaks in resource constrained regions of the globe. With the limited efficacy of cholera vaccines, it is necessary to develop mechanisms to predict cholera occurrence and thereafter devise intervention strategies for mitigating impacts of the disease. Hydroclimatic processes, primarily precipitation and air temperature are related to epidemic and episodic outbreak of cholera. However, due to coarse …

Secretion Of Malaria Transmission-Blocking Proteins From Paratransgenic Bacteria, Nicholas Bongio

Electronic Theses and Dissertations

Malaria is a debilitating and deadly disease that afflicts over 200 million people and kills over 600 thousand each year. Due to quickly evolving drug resistance and lack of an affordable vaccine, novel interventions are needed to fight the Plasmodium parasites that cause malaria. Targeting Plasmodium inside their mosquito hosts is one approach that could complement other preventative and medicinal interventions by reducing the ability of the mosquitoes to transmit the disease to humans. The research presented here uses paratransgenesis, the genetic modification of symbiotic bacteria within the mosquito midgut, to provide antimalarial protein to the mosquito and to interfere …

Programmable Dna Delivery To Cells Using Bioreducible Layer-By-Layer (Lbl) Polyelectrolyte Thin Films, Maria Muniz

Wayne State University Theses

Bioreducible, layer-by-layer (LbL) polyelectrolyte films show great promise for use in biomedical implant and gene-delivery applications. These nanometer-scale thin films can easily be coated onto a variety of implantable surfaces or devices. To achieve proof of concept, HEK-293, NIH/3T3, RAW, and MC3T3 cells were transfected using plasmid DNA with the green fluorescent protein reporter gene (GFP-DNA). In order to optimize transfection, a number of polyelectrolytes and biological components were systematically incorporated into the two similar basic LbL structures. Based on our previous degradation assays, it is shown that cellular interactions in vitro can break down the layers of the thin …

Effectiveness Of Different Corticosterone Administration Methods To Alter Corticosterone Levels In Serum And Depressive-Like Behavior In Female Rats, Jennifer Marie Kott

Wayne State University Theses

There is wide variation in the current literature on rodent models of high levels of chronic stress. This study aims to reduce these discrepancies by investigating the effects of 3 different administration methods of corticosterone (CORT; the endogenous stress hormone in rodents) and the differential effects it has in the female sex. The majority of studies utilize male rodents, while research in female rodents is largely under-investigated. This study will utilize female rats and 3 different administration routes: a) subcutaneous implantation of a CORT pellet, b) CORT in the drinking water, and c) CORT by a daily subcutaneous injection, and …

However, documented in vitro data suggests synergy between several β-lactam antibiotics and daptomycin against resistant organisms. Primary goal of the study was to check various combinations of β-lactam antibiotics with daptomycin (DAP) and assess the potential of synergy and conclude which could be the superior combination. Study also evaluated potential of β-lactam antibiotics to enhance activity of …

Antimicrobial-Resistant Listeria Species From Retail Meat In Metro Detroit, Liziane Da Rocha

Wayne State University Theses

A total of 138 Listeria isolates, including 58 Listeria welshimeri, 44 Listeria monocytogenes, and 36 Listeria innocua, from retail meat were characterized by antimicrobial susceptibility tests against nine antimicrobials. In addition, the 44 L. monocytogenes were analyzed by serotype identification using PCR and genotyping using pulsed-filed gel electrophoresis (PFGE). Resistance to one or two antimicrobials was observed in 32 Listeria (23.2%). No multidrug resistance was identified. Tetracycline resistance was the most common resistance phenotype and identified in 22 Listeria isolates. Low prevalence of resistance to ciprofloxacin, erythromycin, gentamicin, and vancomycin was also detected. L. innocua demonstrated the highest overall prevalence …

The Effects Of Stressors And Stress Hormones On Behavior, Physiology, And Disease Susceptibility In Terrestrial Salamanders, Christopher Fonner

Electronic Theses and Dissertations

Amphibians are exposed to numerous environmental stressors, which may contribute to population declines being experienced by amphibians worldwide. Upon exposure to stressors, animals will release the glucocorticoid hormone, corticosterone (CORT), which typically mediates physiological and behavioral responses for resisting or coping with the stressor. Additionally, amphibians are at risk from a chytrid fungal pathogen, Batrachochytrium dendrobatidis (Bd). After Bd infection, amphibians may develop the potentially fatal disease chytridiomycosis. To better understand how CORT mediates responses to different stressors, and possible immunosuppressive effects of CORT on Bd susceptibility, I performed several experiments. First, I tested the predation stress hypothesis in terrestrial …

Macrophage Cox-2 As A Target For Imaging And Therapy Of Inflammatory Diseases Using Theranostic Nanoemulsions, Sravan Kumar Patel

Electronic Theses and Dissertations

Personalized medicine can be an approach to address the unsatisfactory treatment outcomes in inflammatory conditions such as cancer, arthritis, and cardiovascular diseases. A common feature of chronic diseases is the infiltration of pro-inflammatory macrophages at the disease loci. Infiltrating macrophages have been previously utilized for disease diagnosis. These features suggest that macrophages can be broadly applicable targets for simultaneous therapy and diagnosis. Cyclooxygenase-2 (COX-2), an enzyme involved in the biosynthesis of a lipid inflammatory mediator, prostaglandin E2 (PGE2), is over expressed in macrophages infiltrating the pathological site. Inhibition of PGE2 leads to reduced inflammation, pain and macrophage infiltration. To utilize …

Anti-Herding Regulation, Ian Ayres, Joshua Mitts

Faculty Scholarship

In some contexts, an individual’s choice to mimic the behavior of others, to join the herd, can increase systemic risk and retard the production of information. Herding can thus produce negative externalities. And in such situations, individuals by definition have insufficient incentives to separate from the herd. But the traditional regulatory response to externality problems is to impose across-the-board mandates. Command-and-control regulation tends to displace one pooling equilibrium by moving behavior to a new, mandated pool. Mortgage regulators, for example, might respond to an unregulated equilibrium where most homeowners start with 2% down by imposing a requirement that causes most …

Antibiotic Resistance Mechanisms, Problems, And Solutions, Andrea Sageman

Honors Projects

Antimicrobial resistance is a growing problem in the world today. The Center for Disease Control cited antimicrobial resistance as the second-most significant health threat in 2014 (“CDC year in review: 'Mission: Critical,'” 2014). It is estimated that 23,000 people die from infections caused by antibiotic resistant bacteria every year, and many more people are hospitalized due to drug resistant strains of microorganisms. Antimicrobial resistance makes treatment of infections more difficult, expensive, and dangerous. (“Antibiotic/Antimicrobial resistance,” 2010) The problems caused by drug resistant bacteria will affect almost everyone working in health care in some capacity, and this issue will likely only …

Arsenic Biosand Filters In Developing Countries, Jepkoech Kottutt

Honors Projects

Arsenic is a common pollutant in many developing countries and has been linked to cancer and cardiovascular disease. In this research, biosand filters (BSFs) were modified with iron filings to remove arsenic from contaminated water. Six BSFs (three with 1 kg of iron filings and three without iron filings) were simultaneously dosed with 20 liters of Muskegon Lake water that contained 100 μg/L of arsenic for 30 days. Arsenic concentrations were determined using a HACH low range arsenic test kit. The mean arsenic removal rate for all 3 BSFs with iron filings was 100% for 13 days, but later was …

The Exploration Of The Health Care Systems Of The United States And Belize Including A Cultural Analysis, Laura Hughes

Honors Projects

Health systems throughout the world may have a profoundly different, or extremely similar structure. A well-known, industrialized nation, the United States has an unusual system, which Shi and Singh (2008) describe as “unnecessarily fragmented” (p. 2). Highly unusual for a developed country, this system does not guarantee access to medical care for all of its citizens. On the other hand, a small Central American country more known as a vacation hotspot, Belize ensures health care for all inhabitants of this tropical nation. How can these major differences affect health outcomes? What could these two vastly different countries have in common …
