Role Of Protein Phosphatase-2a In Regulating Monocyte Activation By Soluble And Crystalline Uric Acid In Gout, Sandy Elsayed

Pharmaceutical Sciences (MS) Theses

Gout is a chronic inflammatory disease caused by the phagocytosis of monosodium urate monohydrate (MSU) crystals by monocytes/macrophages resulting in downstream expression and production of interleukin-1 beta (IL-1β) and chemokines. The activation of monocytes by MSU crystals involves the priming of monocytes with danger signals e.g. lipopolysaccharide (LPS) or soluble uric acid (UA), crystal phagocytosis and subsequent NLRP3 inflammasome activation and conversion of pro-IL-1β to active IL-1β. Protein-phosphatase-2A (PP2A) is a serine/threonine phosphatase that plays an important role in cell growth and inflammation. The prodrug Fingolimod (FTY720) and its phosphorylated active metabolite (p-FTY720) activate intracellular PP2A. We hypothesized that monocyte …

Established Adulthood: A New Conception Of Ages 30 To 45, Clare M. Mehta, Jeffrey Jensen Arnett, Carlie G. Palmer, Larry J. Nelson

Faculty Publications

In developed countries, the years from Age 30 to 45 are, for many, the most intense, demanding, and rewarding years of adult life. During this period of the life span most adults must negotiate the intersecting demands of progressing in a chosen career, maintaining an intimate partnership, and caring for children. Successes or difficulties in meeting these simultaneous demands have the potential to profoundly influence the direction of a person's adult life. As such, we believe that it is of critical importance to better understand this developmental period that we call established adulthood. This article provides a new theoretical …

A cross-sectional survey was carried out, followed by qualitative semi-structured interviews.Findings: There were highly significant differences at the 95% probability level between staff groups, unqualified staff being significantly more likely …

Molecular Characterization Of Wolbachia And Its Impact On The Microbiome Of Exotic And United States Ticks, Cailyn G. Bobo

Honors Theses

Wolbachia endosymbionts are obligate intracellular bacteria in the phylum α-Proteobacteria. They infect approximately two-thirds of arthropods including insects and nematodes. These bacteria manipulate host reproductive biology through a series of mechanisms that include feminization of male progeny, parthenogenesis, male killing, and cytoplasmic incompatibility. These features make Wolbachia an effective agent of controlling insect populations, as previously reported in different mosquito species. Likewise, the bacteria have also shown promising ability to interfere with the ability of mosquitoes to transmit several viral pathogens. This study was conducted to fill an existing knowledge gap on the prevalence of Wolbachia in different tick species …

Generating Zika Vaccine Candidates Using Nhumirim Virus As A Backbone, Mariam A. Atobiloye

Honors Theses

Zika virus (ZIKV) is a mosquito-transmitted flavivirus that is causing significant world-wide health concern. There are currently no treatments or vaccines available for this virus, thus, there is an urgent need to develop a safe and effective vaccine to combat ZIKV infection. Nhumirim virus (NHUV) is also a mosquito-transmitted flavivirus, but it is unable to infect humans and other vertebrate animals, making it an ideal candidate to develop chimeric viral vaccines against other disease-causing flaviviruses, such as ZIKV. In this study, we generated chimeric viruses by replacing envelope (E) gene in the genome of NHUV with ZIKV E gene, which …

The Effects Of Disease Contamination On Memory For Touched Objects In Older Adults, Jessica M. Runnels

Honors Theses

Recently it has been shown that individuals have better memory for objects that have been touched by an individual with a contagious disease relative to an individual with a non-contagious disease or who is healthy (Gretz & Huff, 2019). This pattern has been suggested to occur due to the activation of the Behavioral Immune System (BIS)—an avoidance-based system designed to thwart sources of potential pathogens. The BIS has been suggested to operate through an evolutionary-based mechanism in which avoidance of pathogens increases the likelihood of survival, increasing reproductive success. Given this approach, an important question is how the activation of …

Elucidating The Developmental Defects In Zebrafish Associated With The Cardiac Drug Verapamil, Blake Stephan Justis

Graduate Theses/Dissertations

Birth defects are abnormalities in a developing organism that lead to a malformation in structure or function. Over half of birth defects have no determined cause; however, known causes occur by genetic anomalies, exposure to environmental agents (a.k.a. teratogens), or multifactorial reasons. To explain the unknown causes of birth defects, an area of focus in this study is to identify potential teratogens. Identifying these teratogens, is key to preventing future birth defects. An obvious source of teratogens in pregnant women would be that of pharmaceuticals. Thus, a main goal of this study is to identify drugs that cause birth defects. …

Does Aging Identity Moderate The Impact Of Experiences With Familial Ageism On Well-Being?, Emily E. Kinkade

Graduate Theses/Dissertations

The purpose of this study was to begin investigating the effects of ageism in the family context. The current literature has documented the negative impacts that negative stereotypes and negative perceptions of aging has on older adults’ health, mortality, and well-being (Levy, 1996; Levy, 2003). However, the majority of extant research on ageism focuses on age discrimination in the workplace and in healthcare despite the majority of peoples’ time being spent in the family context. Therefore examining experiences of ageism sourced from family members merits study. Walker, Bisconti and Kinkade (in preparation) found evidence that the experience of ageism within …

Clinical Features, Diagnosis And Management Of Covid-19 Patients In The Outdoor Setting, Bushra Jamil

Department of Medicine

In a brief span of a few months, coronavirus disease (COVID-19) pandemic has brought a major paradigm shift in operation of clinical services around the world. Infection may be mild, moderate or severe; many remain asymptomatic. High burden of non-communicable and communicable diseases theoretically puts Pakistani population at increased risk of severe COVID-19 infection. Considering the universal risk of infection, the outpatient services in Pakistan need to be redesigned. Starting with risk assessment of the facility and provision of a dedicated telephone connection, structure and workflow need to be redesigned in order to minimise risk of exposure to healthcare professionals, …

Disease Ecology And Adaptive Management Of Brucellosis In Greater Yellowstone Elk, Gavin G. Cotterill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Brucellosis is a bacterial infection that primarily affects livestock and can also be transmitted to humans. In the Greater Yellowstone Ecosystem (GYE), elk (Cervus canadensis) and bison (Bison bison) are habitual carriers of Brucella abortus, which arrived to the region with cattle over a century ago. The disease was eliminated from cattle in the United States through widespread control efforts, but is now periodically transmitted back to cattle on open rangelands where they can come into contact with fetal tissues and fluids from disease-induced abortions that occur among elk during the late winter and spring. …

Human-Wildlife Interactions In Bryce Canyon National Park, Chad H. Wildermuth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Public lands such as National Parks protect some of America’s most spectacular and iconic natural, cultural, and historic landscapes. These lands are managed with a goal of preserving their unique features for the recreational use of the public. Therefore, it is important to understand the effects, if any, that public visitation has on these natural systems. This study investigated human-wildlife interactions in Bryce Canyon National Park (BRCA), Utah in order to better understand factors that lead to human-wildlife conflicts and how the attitudes and perceptions of visitors affect their actions towards wildlife.

Observations of human-wildlife interactions were observed and measured …

The current coronavirus pandemic is unparalleled in recent memory and fundamentally unique. It has been more than a century since humanity fought the Spanish flu pandemic. That widespread disease devastated a World War I-ravaged population when there was a relative paucity of medical knowledge. Coronavirus, on the other hand, is now befalling upon a developed world with advanced infrastructure and health systems; wherein access to medical information and technology is abundant. Yet, it has proven to be a destroyer of economies and populations without geographical partiality.

This article is meant to be a broad analysis of the virus, which is …

Tumor Necrosis Factor-Alpha Signaling May Contribute To Chronic West Nile Virus Post-Infectious Proinflammatory State, A. Arturo Leis, Marie F. Grill, Brent P. Goodman, Syed B. Sadiq, David J. Sinclair, Parminder J.S. Vig, Fengwei Bai

Faculty Publications

Background: West Nile virus (WNV) causes a spectrum of human disease ranging from a febrile illness (WNV fever) to severe neuroinvasive disease (meningitis, encephalitis, acute flaccid paralysis). Since WNV gained entry into North America in 1999, clinicians caring for WNV survivors have observed persistent neurological symptoms occurring long-after the production of neutralizing antibodies and clearance of the virus. Accordingly, alternative pathogeneses other than direct viral invasion have been hypothesized to explain these post-infectious symptoms. The dominant hypothesis is that antiviral inflammatory responses triggered initially to clear WNV may persist to promote a post-infectious proinflammatory state.

Methods: In 4 serologically-confirmed …

A Model For The Spread Of Infectious Diseases In A Region, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher

Articles

In understanding the dynamics of the spread of an infectious disease, it is important to understand how a town’s place in a network of towns within a region will impact how the disease spreads to that town and from that town. In this article, we take a model for the spread of an infectious disease in a single town and scale it up to simulate a region containing multiple towns. The model is validated by looking at how adding additional towns and commuters influences the outbreak in a single town. We then look at how the centrality of a town …

Immune System Detection Of Pseudomonas Aeruginosa Persister Cells, Grace Elizabeth Himmler

Undergraduate Honors Theses

Persister cells are a subpopulation of bacterial cells known to be tolerant to antimicrobials. Their reduced susceptibility to antimicrobials allows them to be the source of recurrence of many chronic bacterial infections. As a result, it is vital to understand the mechanisms that allow these cells to be able to evade further treatment. Furthermore, it is currently unknown whether the persister cells are detected and killed by the host immune response. In this work I explored the host-pathogen interactions between Pseudomonas aeruginosa cells, both persister and regular, and human macrophages. I hypothesized that persister cells would be engulfed at a …

Has Covid-19 Impacted Price-Weight Relationships And Value Of Gain?, Elliott James Dennis

Extension Farm and Ranch Management News

First paragraph:

In the beginning of COVID-19, much of the attention was focused on managing the redirection of meat product from food service to retail stores. This past month has keenly focused on packing plant closures due to COVID-19 cases among workers and how to manage the supply of fat cattle already ready for slaughter. Fat cattle available for slaughter either cannot get bids or bids are significantly below breakeven prices leaving feedlots with decisions to be made about marketing and placements. The April 2020 Cattle on Feed report (https://usda.library.cornell.edu/concern/publications/m326m174z) revealed March placement decisions. Placements were down about …

Evaluation of surgical antibiotic prophylaxis at a large, tertiary medical center

Surgical site infections (SSI) are a significant cause of morbidity, prolonged hospitalization, and mortality. The cost of a single SSI is estimated to be upward of $25,000 and increases a patient’s length of hospital stay by ~10 days. Our institution has identified inappropriate or less than optimal antimicrobial prophylaxis as a potential contributor in several recent SSI cases. Current literature on this topic has found that there may be …

Not Just Kids –A Case Of Adult Iga Vasculitis, Heidi Reich, Jeff Youker

Providence St. Vincent Internal Medicine 2020

INTRODUCTION: IgA vasculitis, formerly known as HenlochSchonleinPurpura, is generally recognized as the most common form of systemic vasculitis in children, with 90% of cases occurring in the pediatric age group. However, the remaining 10% are noted in adult populations, and often has poorer long term outcomes if not identified and treated quickly. IgAVis commonly associated with streptococcal infections, although additional triggers such as drug ingestions, insect bites, and vaccinations have been described. Symptoms can include palpable purpura, acute abdominal pain, arthralgias, and hematuria. Recognizing the constellation of signs and symptoms is key for expediting appropriate therapy, which may reduce long …
