The Constitutional (And Political) Safeguards Against Impeachment, Victoria Nourse

Missouri Law Review

Will the Trump impeachments inspire a flurry of future presidential impeachments? Will the second Trump impeachment, which occurred after the President left office, spur impeachments of lesser, former government officials? These and other questions emerged during the 2022 Missouri Law Review Symposium and on the Senate floor during the Trump impeachment trials. I have argued that we can make an educated prognosis about these possibilities based on constitutional structure. I called this argument the “political safeguards” of impeachment in my recent book, The Impeachments of Donald Trump: An Introduction to Constitutional Argument. What I called political safeguards, invoking the great …

Weakly-Supervised Tumor Purity Prediction From Frozen H&E Stained Slides, Matthew Brendel, Vanesa Getseva, Majd Al Assaad, Michael Sigouros, Alexandros Sigaras, Troy Kane, Pegah Khosravi, Juan Miguel Mosquera, Olivier Elemento, Iman Hajirasouliha

Publications and Research

Background

Estimating tumor purity is especially important in the age of precision medicine. Purity estimates have been shown to be critical for correction of tumor sequencing results, and higher purity samples allow for more accurate interpretations from next-generation sequencing results. Molecular-based purity estimates using computational approaches require sequencing of tumors, which is both time-consuming and expensive.

Methods

Here we propose an approach, weakly-supervised purity (wsPurity), which can accurately quantify tumor purity within a digitally captured hematoxylin and eosin (H&E) stained histological slide, using several types of cancer from The Cancer Genome Atlas (TCGA) as a proof-of-concept.

Findings

Our model predicts …

Utilizing Computational Methods To Study The Biomolecules, Wenhan Guo

Open Access Theses & Dissertations

COVID-19 is increasingly affecting human health and global economy. Understanding the fundamental mechanisms of Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) is highly demanded to develop treatments for COVID-19. SARS-CoV and SARS-CoV-2 share 92.06% identity in their N protein RBDs' sequences, which results in very similar structures. However, the SARS-CoV-2 is more easily to spread. Utilizing multi-scale computational approaches, this work studied the fundamental mechanisms of the nucleocapsid (N) proteins of SARS-CoV and SARS-CoV-2, including their stabilities and binding strengths with RNAs at different pH values. Electrostatic potential on the surfaces of N proteins show that both the N proteins …

Omarigliptin Attenuates Rotenone-Induced Parkinson's Disease In Rats: Possible Role Of Oxidative Stress, Endoplasmic Reticulum Stress And Immune Modulation, Shereen Mowaka, Haidy E. Michel, Mariam M. Tadros, Moataz S. Hendy, Bassam M. Ayoub

Pharmacy

The current study aimed to explore the potential neuroprotective effect of omarigliptin (OG), an antidiabetic drug that crosses the blood-brain barrier (BBB), in a Parkinson's disease (PD) rotenone-based rat-model. Results showed that OG attenuated motor impairment, histological aberrations, α-synuclein accumulation, and rescued the dopaminergic neurons in rotenone-administered rats. Furthermore, OG halted rotenone-induced oxidative stress; as shown by reduced lipid peroxidation, decline in the oxidative stress sensor (nuclear factor erythroid 2-related factor 2) and its downstream heme oxygenase-1. In addition, OG abrogated neuroinflammation and apoptosis in rotenone-treated rats. Moreover, OG ameliorated endoplasmic reticulum (ER) stress in rotenone-administered rats; as evidenced by …

Lexical And Grammatical Features Of Memoranda Of Agreement (Moa) On Academic Partnerships, Marilu Rañosa Madrunio

Journal of English and Applied Linguistics

In the past decades, internationalization has become a byword in many educational institutions. Higher education institutions are aware that a means by which they can offer good quality education is by engaging in partnerships with international institutions. International linkages established by academic institutions have a wider reach such that teaching and learning, research, community, and extension programs may have an international flavor. In forging partnerships, institutions would sign an agreement called the Memorandum of Agreement (MOA), which stipulates provisions expected from the parties involved. Employing the framework of Johnson and Coulthard (2010) on the linguistic features of legal documents, the …

Harmonica Pedagogy For The Full Inclusion Instrumental Music Classroom, Expanding Opportunities For Students With Disabilities, George Wallace Miklas

Doctoral Dissertations and Projects

The harmonica was once taught in American public schools coast to coast from the 1920s through the 1940s when imports of harmonicas were curtailed due to World War II's efforts. Since then, American public-school instrumental music curricula have long forgotten the only wind instrument that makes music when the student inhales or exhales. The harmonica provides a natural calming effect to the player and medical benefits, including being a tool for overcoming mental health issues and expressing needs and feelings without words. During the era when the harmonica was taught, pedagogy lacked uniformity. Consequently, confusion about the instrument's unique tuning …

Expression And Purification Of The Bacterial Protein Curli Csga And Its Cross-Interactions With Amyloid-B, Leah Grace Cantrell

Honors Theses

One of the main causes of neurodegenerative diseases is aggregation of amyloid proteins that are toxic to the neurons. Proteins like amyloid-β (Aβ) and α-syneuclein (α-syn) form hallmark aggregate lesions that contribute to pathological processes in the brain in Alzheimer and Parkinson’s patients, respectively. Recent ground-breaking studies have suggested a link between the microbiota of the gut and neurodegenerative diseases, called the “gut-brain axis.” It has been long known that the protein, CsgA found in many enteric bacteria, forms amyloid fibers of its own called Curli. Curli fibrils are a structural component of bacterial colonies and maintain the integrity of …

Analysis Of Covid-19 And Vaccine Administration In Mississippi, Megan Sickinger

Honors Theses

In this work, we develop a simple mathematical model to observe the spread of COVID-19 and vaccine administration in Mississippi. Based on the well-known Kermack-McKendrick Susceptible-Infected-Removed epidemiological model, the ASIRD−V model has eight ordinary differential equations that split infected populations and recovered populations into vaccinated and unvaccinated populations. After determining that the system is reliable for real-world applications, we investigate and determine the stability and equilibrium points of this system. The system is found to be disease-free when R0 < 1 and endemic when R0 > 1. We use MATLAB to numerically solve the system and optimize the model’s parameters over four short periods, two with the …

A Comparative Analysis Of Statutory Remedies For Wrongful Convictions In The Fifty States, Abigail St. John

Honors Theses

Thousands of individuals have been wrongfully convicted across the United States. When an exoneration occurs, an individual’s conviction is absolved, and their innocence is proved through newly discovered evidence. While it might be impossible to protect from the errors of the criminal justice system, it is in the hands of the state to compensate the wrongly convicted. There is an abundance of research that focuses on reforming the existing wrongful conviction compensation legislation, but there is a lack of scholarly data that explains the motivations behind this compensation. Moreover, few researchers have considered the role of partisanship and political parties …

Poultry Science Faculty Publications and Presentations

Heat stress (HS) is devastating to poultry production sustainability worldwide. In addition to its adverse effects on growth, welfare, meat quality, and mortality, HS alters the gut integrity, leading to dysbiosis and leaky gut syndrome; however, the underlying mechanisms are not fully defined. Here, we used a high-throughput mass spectrometric metabolomics approach to probe the metabolite profile in the duodenum of modern broilers exposed to acute (AHS, 2 h) or chronic cyclic (CHS, 8 h/day for 2 weeks) HS in comparison with thermoneutral (TN) and pair-fed birds. Ultra high performance liquid chromatography coupled with high resolution mass spectrometry (UHPLC–HRMS) identified …

Feed Composition And Isolate Of Histomonas Meleagridis Alter Horizontal Transmission Of Histomonosis In Turkeys. Proof Of Concept, Thaina L. Barros, Christine N. Vuong, Juan D. Latorre, Roberto S. Cuesta, Elizabeth Mcgill, Samuel J. Rochell, Guillermo Tellez-Isaias, Billy Hargis

Poultry Science Faculty Publications and Presentations

Outbreaks of histomonosis in turkeys are typically initiated by the ingestion of contaminated embryonated eggs of Heterakis gallinarum, potentially present in earthworms and mechanical vectors. Once an outbreak is started, infected turkeys can transmit the disease by horizontal transmission. Factors influencing horizontal transmission of histomonosis are poorly understood. Replication of horizontal transmission in experimental conditions has not been consistent, presenting an obstacle in searching for alternatives to prevent or treat the disease. Two pilot experiments and three validation experiments were conducted in the present study. In pilot experiment 1, one isolate of Histomonas meleagridis (named Buford) was used. Turkeys …

Integration Of Non-Traditional Students: Comparing Traditional And Non-Traditional Students' Sense Of Belong, Michelle Leeann Walbeck

Doctoral Dissertations and Projects

With an ever-increasing number of non-traditional students enrolling each year, the importance of ensuring their academic success falls primarily on the higher education institutions (HEIs). Each institution has its recipe for success and mostly consists of a student success office to assist when non-traditional students begin to show signs of markers for being at-risk. The reactive approach of waiting for students to show signs of struggle is missing the larger picture. The researcher utilized quantitative correlative and predictive correlative studies to determine if a direct correlation existed between non-traditional students’ perceived sense of belonging, which is at the core of …
