Chemical Control Of Turfgrass Diseases 2024, Bruce B. Clarke, Paul Vincelli, Paul Koch, Ming-Yi Chou

Agriculture and Natural Resources Publications

Turfgrasses under intensive management are often subject to outbreaks of infectious diseases. Diseases usually are most damaging when weather or cultural conditions favor the disease-causing agent but not plant growth and vigor. Cultural conditions that predispose turfgrass to diseases include close mowing, inadequate or excessive fertility, light or frequent irrigation, excessive thatch, poor drainage, and shade. Good turf management practices often greatly reduce the impact of disease by promoting healthy plants that are better able to resist infections. Even under good management, however, diseases sometimes cause excessive damage to highly managed turfgrasses. The proper use of fungicides in these instances, …

Dimeric Immunoglobulin A As A Novel Diagnostic Marker Of Measles Infection, Khayriyyah Mohd Hanafiah, Joanne Hiebert, Vanessa Zubach, Alberto Severini, David A. Anderson, Heidi E. Drummer

Biology Faculty/Staff Publications

Despite tremendous measles incidence reduction through universal vaccination, elimination efforts rely on improved surveillance. The detection of anti-measles immunoglobulin M (IgM) by enzyme-linked immunosorbent assay is the standard laboratory diagnostic method. However, true infection is rare, and seroconversion following measles, mumps, and rubella vaccination also generates IgM, which results in low positive predictive values of assays in elimination settings, thus necessitating confirmatory testing. Improved diagnostic tests for measles infection are a World Health Organization research priority. We investigated whether dimeric immunoglobulin A (dIgA), the predominant antibody produced in mucosal immunity, may be a marker of recent or acute measles infection. …

The Less Visible Side Of Transhumanism Is Dangerously Un-Radical, Susan B. Levin

Philosophy: Faculty Publications

According to transhumanists who urge the radical enhancement of human beings, humanity’s top priority should be engineering “posthumans,” whose features would include agelessness. Increasingly, transhumanism is critiqued on foundational grounds rather than based largely on anticipated results of its implementation, such as rising social inequality. This expansion is crucial but insufficient because, despite its radical aim, transhumanism reflects beliefs and attitudes that are evident in the broader culture. With a focus on the yearning to eliminate aging, I consider four of these: a disproportionate reliance on science and technology to address major human challenges; the conceptualization of human beings in …

Corals In Crisis: A Transcriptomic Investigation Of Stony Coral Tissue Loss Disease, Kelsey M. Beavers

Biology Dissertations - Archive

Coral reefs face existential threats due to climate change and human activities. The combined effects of ocean warming, overfishing, pollution, and habitat destruction have fundamentally altered the functionality of coral reefs and are driving a drastic increase in the prevalence and severity of coral disease outbreaks. Stony coral tissue loss disease (SCTLD) has emerged one of the most devastating disturbances to Caribbean reef ecosystems on record. Despite notable progress, the cellular mechanisms driving SCTLD pathogenesis remain poorly understood. To address this issue, my dissertation investigates the gene expression, histopathology, immune protein activity, and symbiont community dynamics involved in SCTLD progression …

Population Genetics Of Green (Chelonia Mydas) And Hawksbill Turtles (Eretmochelys Imbricata) In Grenada, West Indies, Naomi Westlake

School of Biological and Marine Sciences Theses

Sea turtle populations within Grenada are believed to be in decline, consistent with worldwide trends. Conservation strategies for green and hawksbill turtles in Grenada are currently limited by a lack of detailed knowledge of the genetic make-up, life history and migration patterns of the local aggregates of these species. Genetic characterisation provides a means for inferring population diversity and origins for these aggregates and to assess potential impacts from regional and worldwide management strategies. Additionally, chelonid alphaherpesvirus-5 (ChHV5) and ChHV5-associated fibropapillomatosis (FP) have recently been reported within Grenada’s green turtle population, but the epidemiology of the disease in Grenada remains …

To this end, 78 broiler farmers were selected using a non-probability snowball sampling …

Implementation Of A Daily Protocol To Reduce Central Line Days On A Medical-Surgical Unit, Katherine Wickstrom

Doctor of Nursing Practice (DNP) Practice Innovation Projects

Background: Central line associated bloodstream infections (CLABSIs) are preventable healthcare associated infections (HAI) in the United States. CLABSIs are associated with increased length of hospital stays, mortality, and financial implications for both patients and hospital systems. Extensive research has shown implementing CLABSI prevention bundles can reduce infections and costs. These bundles are often misused, highlighting the importance of bundle compliance and education.
Local Problem: A medical surgical unit in the upper Midwest continues to have delayed central line removal despite a CLABSI prevention bundle. Efforts to decrease central line days were identified as a priority.
Methods: Staff completed education on …

From Deference To Indifference: Judicial Review Of The Scope Of Public Health Authority During The Covid-19 Pandemic, Wendy E. Parmet

Saint Louis University Journal of Health Law & Policy

For most of American history, courts have granted public health officials significant deference in construing the scope of their own authority. This changed during the COVID-19 pandemic, especially in the federal courts, where deference was replaced with skepticism as courts used the major questions doctrine to narrow the scope of public health powers. This Article examines this development and considers its implications for public health. Part II begins by recounting the long history of judicial deference to officials’ determination of the scope of their public health powers. Part III notes some of the problems with such deference and the pre-pandemic …

Authority To Improve Or Harm Health: The Public Health Front In A Decades-Long Battle Over Governmental Powers, Sabrina Adler, Sara Bartel, Heather Wong

Saint Louis University Journal of Health Law & Policy

Backlash to local, state, and federal responses to combat COVID-19 has resulted in a small but vocal cohort of legislatures and courts trying to change long-settled and foundational principles of public health decision-making. They have shifted authority away from experts and local decision-makers, limiting emergency response in ways that also impact day-to-day public health efforts. Considering some examples of other recent preemption efforts, it is clear that COVID-era backlash is part of a longer-term deregulatory agenda, often framed as an effort to keep “big government” out of people’s lives and to preserve individual freedoms. However, the impact of such deregulation …

The Model Public-Health Emergency Authority Act, Robert Gatter

Saint Louis University Journal of Health Law & Policy

The Uniform Law Commission recently approved the Model Public-Health Emergency Authority Act (MPHEAA or the Act or the Model Act). The MPHEAA grants governors specific and plenary powers to issue public health emergency orders while also ensuring executive branch transparency and accountability. The Act improves public health emergency preparedness by resecuring the legal foundation for states to respond effectively to future emergencies. However, more work is needed to enhance data collection and support vulnerable populations in emergencies.

This Article discusses the origins of the MPHEAA, key policy and drafting choices the Drafting Committee made in creating the MPHEAA, and the …

Doing More With Less: State Public Health Emergency Powers Post-Pandemic, Kelly J. Deere

Saint Louis University Journal of Health Law & Policy

Three years after COVID-19 arrived in the United States, many governors and public health officials are equipped with fewer—not more—public health emergency powers than at the start of the pandemic. This may seem counterintuitive, considering that this virus has killed more than 1.1 million Americans and counting. While public health emergency powers were stripped on the federal, state, and local level, this loss is most acutely felt at the state executive level. Some state legislatures passed laws banning state and local governments from implementing a mask or vaccine mandate, while others amended their state emergency disaster statutes to limit the …

What Is A Public Health Lawyer Today? Acting For, Against, And Beyond Public Health, Scott Burris

Saint Louis University Journal of Health Law & Policy

Health in America is not looking good. Unique among countries in the Organization for Economic Co-operation and Development, the basic measure of national health—life expectancy—was declining even before COVID-19. Public health, both as a system of institutions and as a profession working to promote longer and healthier lives, is also struggling. The normal insularity of the field’s professional culture—including a lack of legal competency—helped undermine the response to COVID-19, which was dismal by any measure. At this difficult time, this Article considers three different ways public health lawyers can make a contribution to public health as a goal and as …

The Future Of Jacobson V. Massachusetts And Modern Substantive Due Process For Public Health Preparedness, Helen S. Webster

Saint Louis University Journal of Health Law & Policy

Both the threat of public exposure to Ebola in the United States in 2014 and the COVID-19 pandemic beginning in 2020 prompted states to impose quarantine and mask mandates, among other responses, to protect the public’s health. When these state actions were eventually challenged on substantive due process grounds in courts across the nation, judges struggled to determine which legal test applied when reviewing the constitutionality of the state actions. On one hand, courts considered the precedent set forth in Jacobson v. Massachusetts, a 1905 Supreme Court case that upheld a Massachusetts vaccine mandate as a valid exercise of …

An Assessment Of Eastern Box Turtles (Terrapene Carolina Carolina) In North Alabama With A Focus On Ranavirus Prevalence And Urbanization, Emma M. Jordan

Theses

Eastern Box Turtles (Terrapene carolina carolina) are susceptible to many threats, including development, urbanization, and disease. A novel Ranavirus has been attributed to mortality in both captive and wild box turtles, including one known occurrence in a captive box turtle in Alabama, but no further assessment has been made. The aims of this study were to assess if Frog Virus 3-like Ranavirus infects wild box turtles and if its prevalence is related to urbanization in North Alabama, USA. I conducted visual encounter surveys in eight survey areas in North Alabama that occur across a gradient of urbanization and development. Twenty-six …

Covid-19 And Access To Healthcare At The Crossing Of Race, Poverty, And Rurality, Shavonnie R. Carthens

Law Faculty Scholarly Articles

Black Americans make up 7.7 percent of the rural population in the United States. During the COVID-19 pandemic many in this population found themselves at a unique intersection of inequity - being Black, poor, and residing in a rural area. Poverty is a known contributor to negative health outcomes and is a risk factor for death from coronavirus infection. The association between race and poverty, when examining infectivity and mortality rates of COVID-19, have disproportionately devastated Black Americans and other minorities. Further, research indicates the presence of a general “rural mortality penalty” wherein rural Black communities have higher death rates …

Impacts Of Climate Change On Vector-Borne Disease Burden In The United States: Exploring The Epidemiological Evidence, Leah V. Loetman

Honors Theses

Climate change models predict shifts in vector-borne diseases (VBDs) around the world, including in the United States. However, to my knowledge there has yet to be a comprehensive descriptive epidemiological study examining prevalence, geographic distribution, and trends for all tick- and mosquito-borne diseases in the United States. I compiled data from the U.S. Centers for Disease Control (CDC), which publishes yearly case numbers for 17 vector-borne diseases. However, these publications depend on a scattered framework of state regulations regarding disease reporting. I compiled data from the CDC to determine the current geographic distribution, prevalence, and trends of tick- and mosquito-borne …

Odiar Es Proteger: La Respuesta Inevitable Al Origen De Una Pandemia, Haowen Huang

Honors Theses

Esta tesis analiza la causa del odio hacia los asiáticos durante la pandemia de COVID-19, enfocándose específicamente en los casos que tuvieron lugar en España. La prevalencia de discriminación dirigida al origen de una pandemia identificado por la narrativa del brote es cultivada por la persistencia de estereotipos. En el caso de COVID-19, la xenofobia hacia los asiáticos fue el resultado de una construcción histórica que ha estigmatizado su identidad persistentemente, la repetición de la cual es definida en esta tesis como racismo pandémico. La imagen de los asiáticos enfermos fue establecida injustificadamente por la medicina occidental en el siglo …

Reiq-Mediated Alarmone Signalling Regulates Growth, Stress-Induced Biofilm Formation And Spore Accumulation In Clostridioides Difficile, Areej Malik, Adenrele Oludiran, Asia Poudel, Orlando Berumen Alvarez, Charles Woodward, Erin B. Purcell

Chemistry & Biochemistry Faculty Publications

The bacterial stringent response (SR) is a conserved transcriptional reprogramming pathway mediated by the nucleotide signalling alarmones, (pp)pGpp. The SR has been implicated in antibiotic survival in Clostridioides difficile, a biofilm- and spore-forming pathogen that causes resilient, highly recurrent C. difficile infections. The role of the SR in other processes and the effectors by which it regulates C. difficile physiology are unknown. C. difficile RelQ is a clostridial alarmone synthetase. Deletion of relQ dysregulates C. difficile growth in unstressed conditions, affects susceptibility to antibiotic and oxidative stressors and drastically reduces biofilm formation. While wild-type C. difficile displays increased biofilm …
