© 2019, The Author(s), under exclusive licence to Springer Nature America, Inc. The molecular and cellular processes that lead to renal damage and to the heterogeneity of lupus nephritis (LN) are not well understood. We applied single-cell RNA sequencing (scRNA-seq) to renal biopsies from patients with LN and evaluated skin biopsies as a potential source of diagnostic and prognostic markers of renal disease. Type I interferon (IFN)-response signatures in tubular cells and keratinocytes distinguished patients with LN from healthy control subjects. Moreover, a high IFN-response signature and fibrotic signature in tubular cells were each associated with failure to respond to …

© 2019 The Author(s). Background: The polymeric immunoglobulin receptor (pIgR) maintains the integrity of epithelial barriers by transporting polymeric antibodies and antigens through the epithelial mucosa into the lumen. In this study, we examined the role of pIgR in maintaining gut barrier integrity, which is important for the normal development in mice. Methods: Cohorts of pIgR -/- mice and their wildtype controls were housed under Specific Pathogen Free (SPF) conditions and monitored for weight gain as an indicator of development over time. The general physiology of the gastrointestinal tract was analysed using immunohistochemistry in young (8-12 weeks of age) and …

OBJECTIVES: Idiopathic inflammatory myopathies (IIM) are a spectrum of rare autoimmune diseases characterised clinically by muscle weakness and heterogeneous systemic organ involvement. The strongest genetic risk is within the major histocompatibility complex (MHC). Since autoantibody presence defines specific clinical subgroups of IIM, we aimed to correlate serotype and genotype, to identify novel risk variants in the MHC region that co-occur with IIM autoantibodies.

METHODS: We collected available autoantibody data in our cohort of 2582 Caucasian patients with IIM. High resolution human leucocyte antigen (HLA) alleles and corresponding amino acid sequences were imputed using SNP2HLA from existing genotyping data and tested …

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. Periodontitis is a common infectious disease characterized by loss of tooth-supporting structures, which eventually leads to tooth loss. The heavy burden of periodontal disease and its negative consequence on the patient’s quality of life indicate a strong need for developing effective therapies. According to the World Health Organization, 10–15% of the global population suffers from severe periodontitis. Advances in understanding the etiology, epidemiology and microbiology of periodontal pocket flora have called for antibacterial therapeutic strategies for periodontitis treatment. Currently, antimicrobial strategies combining with polymer science have attracted tremendous interest in the …

Role Of Cytochrome P450 2b6 Polymorphisms In Unexpected Methadone Death, Taha Ahmad

Theses, Dissertations and Capstones

Methadone is a synthetic, long-acting opioid prescribed as an analgesic for chronic pain. It has a single chiral center forming two enantiomers, (R)-methadone and (S)-methadone, each having specific pharmacological actions. Concentrations of (R)- and (S)-methadone above therapeutic levels have the ability to cause serious, life-threatening, and fatal side effects. Cardiotoxicity is caused by elevated (S)-methadone levels by prolonging the QT interval of the heart’s electrical cycle. In 2014, methadone accounted for only 1% of all opioids prescribed for pain, but was responsible for 3,400 of the 14,838 individuals (~23%) who died in the United States from overdoses due to prescription …

Introduction

Low- and middle-income countries (LMICs) are continuing to experience a “triple burden” of disease - traumatic injury, non-communicable diseases (NCDs), and communicable disease with maternal and neonatal conditions (CD&Ms). The epidemiology of this triad is not well characterised and poses significant challenges to resource allocations, administration, and education of emergency care providers. The data collected in this study provide a comprehensive description of the emergency centre at Kenya's largest public tertiary care hospital.

Methods

This study is a retrospective chart review conducted at Kenyatta National Hospital of all patient encounters over a four-month period. Data were collected from financial …

Understanding Flu Vaccination Acceptance Among U.S. Adults: The Health Belief Model And Media Sources, Tong Xie, Connor Grady, Michael Cacciatore, Glen Nowak

International Crisis and Risk Communication Conference

Based on previous studies about the Health Belief Model (HBM) and the reinforcing relationship between media selectivity or preference and individual’s behavior, this study used a national representative adult sample to assess flu vaccination as the result of an appraisal of relevant health beliefs, trust towards the authoritative entities (e.g. CDC & FDA) and vaccine-related media information, in addition to one’s existing behavior pattern. Results showed that not-vaccinated individuals differ significantly in their vaccine-related health believes and the trust towards the authoritative information sources. This group acquired less recommendation from health care providers and more negative sentiments about flu vaccine …

Neutrophil Extracellular Traps In Breast Cancer And Beyond: Current Perspectives On Net Stimuli, Thrombosis And Metastasis, And Clinical Utility For Diagnosis And Treatment, Hunter T. Snoderly, Brian A. Boone, Margaret F. Bennewitz

Faculty & Staff Scholarship

Abstract

The formation of neutrophil extracellular traps (NETs), known as NETosis, was first observed as a novel immune response to bacterial infection, but has since been found to occur abnormally in a variety of other inflammatory disease states including cancer. Breast cancer is the most commonly diagnosed malignancy in women. In breast cancer, NETosis has been linked to increased disease progression, metastasis, and complications such as venous thromboembolism. NET-targeted therapies have shown success in preclinical cancer models and may prove valuable clinical targets in slowing or halting tumor progression in breast cancer patients. We will briefly outline the mechanisms by …

During the water crisis in Flint, Michigan, USA (2014–2015), 2 outbreaks of Legionnaires’ disease occurred in Genesee County, Michigan. We compared whole-genome sequences of 10 clinical Legionella pneumophila isolates submitted to a laboratory in Genesee County during the second outbreak with 103 water isolates collected the following year. We documented a genetically diverse range of L. pneumophila strains across clinical and water isolates. Isolates belonging to 1 clade (3 clinical isolates, 3 water isolates from a Flint hospital, 1 water isolate from a Flint residence, and the reference Paris strain) had a high degree of similarity (2–1,062 single-nucleotide polymorphisms), all …

Bordetella Pertussis Can Be Motile And Express Flagellum-Like Structures, Cassandra L. Hoffman, Laura A. Gonyar, Federico Zacca, Federico Sisti, Julieta Fernandez, Ting Wong, F. Heath Damron, Erik L. Hewlett

Faculty & Staff Scholarship

ABSTRACT Bordetella bronchiseptica encodes and expresses a flagellar apparatus. In contrast, Bordetella pertussis, the causative agent of whooping cough, has historically been described as a nonmotile and nonflagellated organism. The previous statements that B. pertussis was a nonmotile organism were consistent with a stop codon located in the flagellar biosynthesis gene, flhA, discovered when the B. pertussis Tohama I genome was sequenced and analyzed by Parkhill et al. in 2003 (J. Parkhill, M. Sebaihia, A. Preston, L. D. Murphy, et al., Nat Genet, 35:32– 40, 2003, https://doi.org/10 .1038/ng1227). The stop codon has subsequently been found in all annotated genomes. Parkhill …

Analysis Of The In Vivo Transcriptome Of Bordetella Pertussis During Infection Of Mice, Ting Y. Wong, Jesse M. Hall, Evan S. Nowak, Dylan T. Boehm, Laura A. Gonyar, Erik L. Hewlwtt, Joshua C. Eby, Mariette Barbier, F H. Damron

Faculty & Staff Scholarship

Bordetella pertussis causes the disease whooping cough through coordinated control of virulence factors by the Bordetella virulence gene system. Microarrays and, more recently, RNA sequencing (RNA-seq) have been used to describe in vitro gene expression profiles of B. pertussis and other pathogens. In previous studies, we have analyzed the in vitro gene expression profiles of B. pertussis, and we hypothesize that the infection transcriptome profile in vivo is significantly different from that under laboratory growth conditions. To study the infection transcriptome of B. pertussis, we developed a simple filtration technique for isolation of bacteria from infected lungs. The work flow …

Retinitis pigmentosa (RP) initiates with diminished rod photoreceptor function, causing peripheral and nighttime vision loss. However, subsequent loss of cone function and high-resolution daylight and color vision is most debilitating. Visual pigment-rich photoreceptor outer segments (OS) undergo phagocytosis by the retinal pigment epithelium (RPE), and the RPE also acts as a blood-outer retinal barrier transporting nutrients, including glucose, to photoreceptors. We provide evidence that contact between externalized phosphatidylserine (PS) on OS tips and apical RPE receptors activates Akt, linking phagocytosis with glucose transport to photoreceptors for new OS synthesis. As abundant mutant rod OS tips shorten in RP, Akt activation …

The Scientist And American Cinema: Trends And Case Studies, Ciara Wardlow

Honors Thesis Collection

This thesis explores historical trends in the depiction of scientists in popular film from 1931 to present, emphasizing how both scientific developments and current events influence the characterization of movie scientists and how these popular depictions of scientists can, in turn, have real-world influence. In addition to giving a historical overview of these trends, this thesis examines case studies looking specifically at the evolving relationship between space science and cinema, the representation of historical scientists in biographical films, and the evolution of scientist characters in two scientist-starring short stories, "Who Goes There?" and "The Fly," and their respective film adaptations …

Acylated Sulfa Drugs: A Phthesis On The Synthesis Of Acylated Sulfa Compounds In Connection With Antitubercular Drug Design, Catherine Pugh

Honors Thesis Collection

Tuberculosis (TB) is an infectious disease caused by the organism Mycobacterium tuberculosis (MTB). Improved sanitation and successful chemotherapy have largely eliminated TB in industrialized countries, but it remains a serious threat to lower socio-economic classes, the immunocompromised population, and developing countries where industrialization is just taking hold. Although two new drugs have surfaced in the last decade, they are largely reserved for compassionate cases because of the severity of their side effects. The first-line TB treatment prescribed by the World Health Organization and the Center for Disease Control and Prevention remains the comparatively small number of drugs synthesized or …
