Elucidating The Effect Of Iron Acquisition Systems In Klebsiella Pneumoniae On Susceptibility To The Novel Siderophore-Cephalosporin Cefiderocol, Lana Daoud, Farah Al-Marzooq, Carole Ayoub Moubareck, Akela Ghazawi, Timothy Collyns

All Works

BACKGROUND: Cefiderocol (CFDC) is a novel siderophore-cephalosporin, effective against multidrug-resistant Gram-negative bacteria. As it has a siderophore side chain, it can utilize iron acquisition systems for penetration of the bacterial outer membrane. We aimed to elucidate the role of siderophores and iron uptake receptors in defining Klebsiella pneumoniae susceptibility to CFDC. METHODS: Initially, 103 K. pneumoniae strains were characterized for susceptibility to different antibiotics including CFDC. CFDC minimum inhibitory concentrations (MIC) were determined in iron-depleted and iron-enriched conditions. Iron uptake genes including siderophores, their receptors, ferric citrate (fecA) and iron uptake (kfu) receptors were detected by PCR in all the …

A Comprehensive Review Of Duchenne Muscular Dystrophy: Genetics, Clinical Presentation, Diagnosis, And Treatment, Kylie A. Limback, William D. Jacobus, Amber Wiggins-Mcdaniel, Ramon E. Newman, Robert A. White

Faculty and Staff Publications

Duchenne Muscular Dystrophy (DMD) is a genetic disorder involving progressive muscle deterioration leading to loss of mobility, cardiomyopathy, and respiratory complications leading to an early death by the fourth decade of life. Males are affected more often as DMD results from a mutation in the dystrophin gene residing on the X chromosome. The DMD genetic mutation results in a complete functional lack of dystrophin, which culminates as an inadequate connection between the intracellular actin filaments and the extracellular skeleton of muscle. Boys affected by DMD clinically present with muscle weakness before age five, are often wheelchair-bound by age 12, and …

BACKGROUND: Hyaluronic acid (HA) promotes cancer metastasis; however, the currently approved treatments do not target HA. Metastatic renal carcinoma (mRCC) is an incurable disease. Sorafenib (SF) is a modestly effective antiangiogenic drug for mRCC. Although only endothelial cells express known SF targets, SF is cytotoxic to RCC cells at concentrations higher than the pharmacological-dose (5-µM). Using patient cohorts, mRCC models, and SF combination with 4-methylumbelliferone (MU), we discovered an SF target in RCC cells and targeted it for treatment.

METHODS: We analyzed HA-synthase (HAS1, HAS2, HAS3) expression in RCC cells and clinical (n = 129), TCGA-KIRC (n = 542), and …

Intestinal Iga-Coated Bacteria In Healthy- And Altered-Microbiomes (Dysbiosis) And Predictive Value In Successful Fecal Microbiota Transplantation, Herbert L Dupont, Zhi-Dong Jiang, Ashley S Alexander, Andrew W Dupont, Eric L Brown

Faculty, Staff and Student Publications

IgA-coated bacteria in the gut (IgA-biome) provide a homeostatic function in healthy people through inhibition of microbial invaders and by protecting the epithelial monolayer of the gut. The laboratory methods used to detect this group of bacteria require flow cytometry and DNA sequencing (IgA-Seq). With dysbiosis (reduced diversity of the microbiome), the IgA-biome also is impaired. In the presence of enteric infection, oral vaccines, or an intestinal inflammatory disorder, the IgA-biome focuses on the pathogenic bacteria or foreign antigens, while in other chronic diseases associated with dysbiosis, the IgA-biome is reduced in capacity. Fecal microbiota transplantation (FMT), the use of …

Background: The impact of gene mutations typically associated with myelodysplastic syndrome (MDS) in acute myeloid leukemia (AML) with NPM1 mutation is unclear. Methods: Using a cohort of 107 patients with NPM1-mutated AML treated with risk-adapted therapy, we compared survival outcomes of patients without MDS-related gene mutations (group A) with those carrying concurrent FLT3-ITD (group B) or with MDS-related gene mutations (group C). Minimal measurable disease (MMD) status assessed by multiparameter flow cytometry (MFC), polymerase chain reaction (PCR), and/or next-generation sequencing (NGS) were reviewed. Results: Among the 69 patients treated intensively, group C showed significantly inferior progression-free survival (PFS, p < 0.0001) but not overall survival (OS, p = 0.055) compared to group A. Though groups A and C had a similar MMD rate, group C patients had a higher relapse rate (p = 0.016). Relapse correlated with MMD status at the end of cycle 2 induction (p = 0.023). Survival of group C patients was similar to that of group B. Conclusion: MDS-related gene mutations are associated with an inferior survival in NPM1-mutated AML.

Relationships Between Principles Of Gems Classification In Bhoja’S Yuktikalpataru And Ayurvedic Principles, Aroonwan Kongmebhol

Journal of Letters

According to the lapidary section in Yuktikalpataru ascribed to King Bhoja, some precious stones were classified by manifold principles, suspected to be predominantly based on Ayurvedic concepts. Research is needed to establish whether these classification schemes were truly based on Ayurvedic theory. This research paper examines gem classification as depicted in the Yuktikalpataru and its conformity with Ayurvedic-based schemes of classification. Research data were selected from descriptions of diamond (vajraparīkṣā) and pearl testing (muktāparīkṣā). Results show significant influence on gem classification of some basic principles of Ayurveda: a classification scheme based, with a few exceptions, on …

因子分析和项目反应理论的潜变量估计, David Thissen, Anne Thissen-Roe

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

本文对项目反应理论 (item response theory; IRT) 和因子分析 (factor analysis) 模型潜变量 (latent variable) 得分估计方法的历史发展进行综述，指出两种理论中常用的因子得分估计本质上是相同的，只是计算方法不同而已。不同的程序已经被用于推导因子得分和IRT潜变量的估计，并且产生了不同的计算过程。由于潜变量得分的使用情况不同，IRT和因子分析解决挑战的方案不同。对偏差纠正的需求不同，两种理论体系提出了不同的纠正方法。尽管IRT模型不具有因子分析模型的高斯似然，但采用正态近似方法使得IRT与因子分析模型的得分计算在很多情况下是非常相似的。最后，尽管两种理论因子得分估计问题上是相同的，但因子分析多年一直处于因子得分不确定性 (factor score indeterminacy) 的争议之中，而IRT却没有。这是历史的产物，也是IRT和因子分析文章中模型表达方式不同的结果。此外，IRT不存在不确定性问题的争议，有利于阐明以下立场，即不确定性并不是一个问题。

Latent Variable Estimation In Factor Analysis And Item Response Theory, David Thissen, Anne Thissen-Roe

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

This essay sketches the historical development of latent variable scoring procedures in the item response theory (IRT) and factor analysis literatures, observing that the most commonly used score estimates in both traditions are fundamentally the same; only methods of calculation differ. Different procedures have been used to derive factor score estimates and latent variable estimates in IRT, and different computational procedures have been the result. Due to differences in the context of score usage, challenges have led to different solutions in the IRT and factor analytic traditions. The needs for bias corrections differ, as do the corrections that have been …

Community Circles In Response To Restorative Justice Research And Critique, Hannah Edber

Journal of Educational Research and Practice

Zero-tolerance discipline in schools has resulted in disproportionate referrals, suspensions, and expulsions for Black students, students with disabilities, and low-income students of color. Restorative Justice (RJ) seeks to intervene in these patterns by emphasizing community interconnectedness and a discourse of harm, accountability, and repair. Although RJ has been shown to increase school connectedness and decrease suspensions and expulsions, teachers and students using RJ (as a response to discipline issues) report varying degrees of satisfaction with the framework. Frustrations can include limited time and limited depth of conversations with students who have caused harm, so that root causes of behavior are …

A computing device (e.g., a smartphone, a smartwatch, smartglasses, smart headphones (including earbuds), a laptop computer, a tablet computer, a vehicle head unit, etc.) may execute an application programming interface (API) that outputs pairing information per a universal or general standard. For example, the API may process communication parameters uniquely specified by an original equipment manufacturer (OEM) to identify key attributes and features. The API may insert the identified key attributes and features into a custom specification having a common format. In this way, the API may generalize, abstract, or otherwise standardize communication parameters specifications that were originally uniquely defined. …

Two Distinctions About Eating Animals, A.G. Holdier

Between the Species

In this paper I describe two distinctions about what “eating animals” entails which are often confused in conversations or arguments aimed against meat-based diets and try to show how both distinctions, on their own lights, ultimately support a concern for all fellow creatures, regardless of species or other biological categories. The distinctions in question are: the distinction between moral and nonmoral actions, presumptions about which serve to define whether or not particular topics (like meat consumption) deserve moral consideration whatsoever, and the distinction between moral and immoral actions, about which suppositions bear on both reflexive and considered moral …

An Eolian Dust Origin For Clastic Fines Of Devono-Mississippian Mudrocks Of The Greater North American Midcontinent, Austin J. Mcglannan, Alicia Bonar, Lily Pfeifer, Sebastian Steinig, Paul Valdes, Steven Adams, David Duarte, Benmadi Milad, Andrew Cullen, Gerilyn S. Soreghan

School of Earth & Environment Departmental Research

Upper Devonian and Lower–Middle Mississippian strata of the North American midcontinent are ubiquitously fine-grained and silt-rich, comprising both so-called shale as well as argillaceous limestone (or calcareous siltstone) that accumulated in the Laurentian epeiric sea. Although long recognized as recording marine deposition, the origin and transport of the fine-grained siliciclastic material in these units remains enigmatic because they do not connect to any proximal deltaic feeder systems. Here, we present new data on grain size, whole-rock geochemistry, mineralogy, and U-Pb detrital-zircon geochronology from units across Oklahoma; we then integrate these data with models of surface wind circulation, refined paleogeographic reconstructions, …

Over-Policing And Under-Protecting In American Cities, Margaret Hession

Honors Program Theses and Projects

In recent years there have been numerous protests all over the United States focused on the over-policing of African Americans by law enforcement. Those involved are protesting against a term known as over-policing, the blatant brutality and senseless murders, that have taken place for decades but have been made ever more visible by our modern media channels. “Over-policing allows police to use excessive force and brutalize disenfranchised neighborhoods and target people of color indiscriminately. Ironically, as politicians take a “tough on crime” stance, violence has actually gone down, but police budgets and presence have increased. The American criminal justice system …
