Discovering The Immune Cell Landscape In Ipf By Whole Lung Single Cell Transcriptomics, Jonas C. Schupp, Taylor Adams
Yale Day of Data
Single cell transcriptomes of 27 IPF, 13 COPD and 14 control lungs were established. Cells were clustered into major cell types, then the immune cells consisting of 116,057 myeloid, 4,742 B-, and 19,165 T-& NK-cells were analyzed and subclustered. Subclustering revealed IPF-associated unique gene expression profiles subpopulations that were specific to the IPF lung. For example, we could identify an IPF-specific macrophage subpopulation which showed a pro-fibrotic profile characterized by SPP1, CHIT1, CCL18, SPARC, LGMN, CTSK, and MMP9 gene expression. Antagonistically, NK- and cytotoxic T-cells revealed a significantly increased expression of the protease inhibitors A2M and PZP ...

Cancer-induced cachexia, characterized by systemic inflammation, body weight loss, adipose tissue (AT) remodeling and muscle wasting, is a malignant metabolic syndrome with undefined etiology. Here, we show that both genetic ablation and pharmacological inhibition of TLR4 were able to attenuate the main clinical markers of cachexia in mice bearing Lewis lung carcinoma (LLC). AT remodelling was not found in LLC tumor-bearing (TB) TLR4(-/-) mice due to reduced macrophage infiltration and adipocyte atrophy. TLR4(-/-) mice were also resistant to cold-induced browning of subcutaneous AT (scAT). Importantly, pharmacological inhibition of TLR4 (Atorvastatin) reproduced the main protective effect against AT remodeling found in ...

BACKGROUND: Hyperendemic circulation of all four types of dengue virus (DENV-1-4) has expanded globally, fueling concern for increased incidence of severe dengue. While the majority of DENV infections are subclinical, epidemiologic studies suggest that type-cross-reactive immunity can influence disease outcome in subsequent infections. The mechanisms controlling these differential clinical outcomes remain poorly defined.
METHODOLOGY/PRINCIPAL FINDINGS: Blood samples were collected from a cohort of school-aged Thai children who subsequently experienced a subclinical DENV infection or developed dengue illness. PBMC collected prior to infection were stimulated in vitro with DENV and the secretion of 30 cytokines was measured using a multiplexed ...

Doctor of Nursing Practice (DNP) Translational and Clinical Research Projects
Immigrants and refugees represent an underserved population in need of quality, accessible, and culturally appropriate healthcare and education. Diabetes is a chronic condition frequently seen in this population. The author utilized the Wagner Chronic Care Model (CCM) as a theoretical framework for planning diabetes education delivery in this diverse population. Studies report significant health disparities in diabetes care and subsequent poor diabetes quality indicators in refugees and immigrants. Research has found that culturally sensitive diabetes education can improve diabetes outcomes in ethnically diverse populations. The author implemented a translational project to develop and evaluate a video-based diabetes health education intervention ...
Multiple Regression Models To Analyze Length Of Hospitalization Due To Nosocomial Infections In U.S. Hospitals, 2018 Cleveland State University
Multiple Regression Models To Analyze Length Of Hospitalization Due To Nosocomial Infections In U.S. Hospitals, Ernest M. Oleksy
The Downtown Review
Nosocomial diseases are a serious concern and detriment to hospitals’ abilities to provide appropriate patient care. Bearing this in mind, an effort must be made to determine whether infection surveillance and control programs have reduced the rates of nosocomial infection at U.S. hospitals. The data that were studied were obtained as part of the Study on the Efficacy of Nosocomial Infection Control (SENIC) and used to develop a model of what variables most contribute to a patient’s length of stay at the Cleveland Clinic (Quade et al, 1980).

HIV-1-infected people who take drugs that suppress viremia to undetectable levels are protected from developing AIDS. Nonetheless, HIV-1 establishes proviruses in long-lived CD4(+) memory T cells, and perhaps other cell types, that preclude elimination of the virus even after years of continuous antiviral therapy. Here we show that the HIV-1 provirus activates innate immune signaling in isolated dendritic cells, macrophages, and CD4(+) T cells. Immune activation requires transcription from the HIV-1 provirus and expression of CRM1-dependent, Rev-dependent, RRE-containing, unspliced HIV-1 RNA. If rev is provided in trans, all HIV-1 coding sequences are dispensable for activation except those cis-acting sequences required ...

Lutein (L) and zeaxanthin (Z) are nutrients that reduce the risk of age-related macular degeneration (AMD). As micronutrients that selectively accumulate in the retina of the eye, L/Z can protect the macula from oxidative damage that contributes to AMD. This review will discuss the role of genes as a mediator between increased intake of dietary L/Z and decreased risk of AMD. Figure 1 outlines a pathway of L/Z that is subject to genetic influences, from 1) the diet to 2) the bloodstream to 3) the retina of the eye. First, L/Z are carotenoids that cannot be ...

The peptidylarginine deiminases PAD2 and PAD4 are implicated in the pathogenesis of several autoimmune diseases. PAD4 may be pathogenic in systemic lupus erythematosus (SLE) through its role in neutrophil extracellular trap (NET) formation that promotes autoantigen externalization, immune dysregulation, and organ damage. The role of this enzyme in mouse models of autoimmunity remains unclear, as pan-PAD chemical inhibitors improve clinical phenotype, whereas PAD4-KO models have given conflicting results. The role of PAD2 in SLE has not been investigated. The differential roles of PAD2 and PAD4 in TLR-7-dependent lupus autoimmunity were examined. Padi4-/- displayed decreased autoantibodies, type I IFN responses, immune ...

Trisomy Silencing By Xist Normalizes Down Syndrome Cell Pathogenesis Demonstrated For Hematopoietic Defects In Vitro, Jen-Chieh Chiang, Jun Jiang, Peter E. Newburger, Jeanne B. Lawrence
Open Access Articles
We previously demonstrated that an integrated XIST transgene can broadly repress one chromosome 21 in Down syndrome (DS) pluripotent cells. Here we address whether trisomy-silencing can normalize cell function and development sufficiently to correct cell pathogenesis, tested in an in vitro model of human fetal hematopoiesis, for which DS cellular phenotypes are best known. XIST induction in four transgenic clones reproducibly corrected over-production of megakaryocytes and erythrocytes, key to DS myeloproliferative disorder and leukemia. A contrasting increase in neural stem and iPS cells shows cell-type specificity, supporting this approach successfully rebalances the hematopoietic developmental program. Given this, we next used ...

Campylobacter jejuni is a prevalent infectious enteritis mainly foodborne from chickens. Despite of reducing C. jejuni food contamination dramatically decreases campylobacteriosis, few effective approaches are available for the bacterial reduction in chickens. The aim of this study was to use microbial metabolic product deoxycholic acid (DCA) to reduce C. jejuni chicken colonization. Broiler chicks were fed 0 or 1.5 g/kg DCA, lithocholic acid (LCA), or urodeoxycholic acid (UDCA) in diets or orally gavaged with cholic acid (CA, 1.5g/kg body weight). Birds were also transplanted with DCA modulated anaerobes (DCA-Anearo) or aerobes (DCA-Aero). Birds were infected with ...

Examining The Impact Of Hiv Medical And Social Case Management Program On Viral Load For Clients Living With Hiv/Aids In Nebraska, Abdulla Munir
Service Learning/Capstone Experience
Case management (CM) is one of the standard practices that has been implemented since 1990 to help people living with HIV/AIDS (PLWHA) in the United States. The program is designed for low-income populations and it aims to address the barriers related to access to health care and improve the HIV outcomes. Previous studies identified a positive association with the provision of CM and improvement in viral outcomes. Increasing the viral suppression rates among HIV diagnosed individuals proved to reduce the risk of transmitting the infection, and disease incidence. Although CM program is provided to Nebraskans diagnosed with HIV ...

Risky Business: Millennials’ Protection Motivation Factors For Norovirus Outbreaks On College Campuses, Dylan Conrad Martinez
Theses and Dissertations
The risk and severity of hNoV transmission is obscurely recognized to foodservice millennial customers. Most commonly associated with cruise ships, consumers are not aware of its full potential to strike at other locations, especially college campuses. For the foodservice industry and the university community, it is imperative that a proactive method for increasing millennials’ motivation to practice mitigation methods emerges to reduce future hNoV outbreaks on college campuses. Research has shown that students can play a major role in the spread of hNoV on college campuses. Therefore, the purpose of these studies is to examine motivations for health protective behaviors ...

BACKGROUND: Nanomedicine offers an excellent opportunity to tackle treatment-refractory malignancies by enhancing the delivery of therapeutics to the tumor site. High endothelial venules (HEVs) are found primarily in lymph nodes or formed de novo in peripheral tissues during inflammatory responses. They express peripheral node addressin (PNAd), which is recognized by the monoclonal antibody MECA79.
METHODS: Here, we demonstrated that HEVs form de novo in human pancreatic ductal adenocarcinoma (PDAC). We engineered MECA79 coated nanoparticles (MECA79-NPs) that recognize these ectopic HEVs in PDAC.
FINDINGS: The trafficking of MECA79-NPs following intravenous delivery to human PDAC implanted in a humanized mouse model was ...
