Unraveling The Intercellular Communication Disruption And Key Pathways In Alzheimer’S Disease: An Integrative Study Of Single-Nucleus Transcriptomes And Genetic Association, Andi Liu, Brisa S Fernandes, Citu Citu, Zhongming Zhao

Faculty, Staff and Student Publications

BACKGROUND: Recently, single-nucleus RNA-seq (snRNA-seq) analyses have revealed important cellular and functional features of Alzheimer's disease (AD), a prevalent neurodegenerative disease. However, our knowledge regarding intercellular communication mediated by dysregulated ligand-receptor (LR) interactions remains very limited in AD brains.

METHODS: We systematically assessed the intercellular communication networks by using a discovery snRNA-seq dataset comprising 69,499 nuclei from 48 human postmortem prefrontal cortex (PFC) samples. We replicated the findings using an independent snRNA-seq dataset of 56,440 nuclei from 18 PFC samples. By integrating genetic signals from AD genome-wide association studies (GWAS) summary statistics and whole genome sequencing (WGS) data, we prioritized …

Short-Stay Units Vs Routine Admission From The Emergency Department In Patients With Acute Heart Failure: The Ssu-Ahf Randomized Clinical Trial, Peter S Pang, Douglas Char, Et Al.

2020-Current year OA Pubs

IMPORTANCE: More than 80% of patients who present to the emergency department (ED) with acute heart failure (AHF) are hospitalized. With more than 1 million annual hospitalizations for AHF in the US, safe and effective alternatives are needed. Care for AHF in short-stay units (SSUs) may be safe and more efficient than hospitalization, especially for lower-risk patients, but randomized clinical trial data are lacking.

OBJECTIVE: To compare the effectiveness of SSU care vs hospitalization in lower-risk patients with AHF.

DESIGN, SETTING, AND PARTICIPANTS: This multicenter randomized clinical trial randomly assigned low-risk patients with AHF 1:1 to SSU or hospital admission …

Faculty, Staff and Students Publications

Infections caused by carbapenem-resistant Acinetobacter baumannii (CRAB) present significant healthcare challenges due to limited treatment options. Bacteriophage (phage) therapy offers potential as an alternative treatment. However, the high host specificity of phages poses challenges for their therapeutic application. To broaden the phage spectrum, laboratory-based phage training using the Appelmans protocol was employed in this study. As a result, the protocol successfully expanded the host range of a phage cocktail targeting CRAB. Further analysis revealed that the expanded host range phages isolated from the output cocktail were identified as recombinant derivatives originating from prophages induced from encountered bacterial strains. These findings …

Faculty, Staff and Student Publications

Bat-borne emerging zoonotic viruses cause major outbreaks, such as the Ebola virus, Nipah virus, and/or beta coronavirus. Pteropine orthoreovirus (PRV), whose spillover event occurred from fruits bats to humans, causes respiratory syndrome in humans widely in South East Asia. Repurposing approved drugs against PRV is an effective tool to confront future PRV pandemics. We screened 2,943 compounds in an FDA-approved drug library and identified eight hit compounds that reduce viral cytopathic effects on cultured Vero cells. Real-time quantitative PCR analysis revealed that six of eight hit compounds significantly inhibited PRV replication. Among them, micafungin used clinically as an antifungal drug, …

Lipid Nanodisc Scaffold And Size Alter The Structure Of A Pentameric Ligand-Gated Ion Channel, Vikram Dalal, Mark J Arcario, John T Petroff 2nd, Brandon K Tan, Noah M Dietzen, Michael J Rau, James A J Fitzpatrick, Grace Brannigan, Wayland W L Cheng

2020-Current year OA Pubs

Lipid nanodiscs have become a standard tool for studying membrane proteins, including using single particle cryo-electron microscopy (cryo-EM). We find that reconstituting the pentameric ligand-gated ion channel (pLGIC), Erwinia ligand-gated ion channel (ELIC), in different nanodiscs produces distinct structures by cryo-EM. The effect of the nanodisc on ELIC structure extends to the extracellular domain and agonist binding site. Additionally, molecular dynamic simulations indicate that nanodiscs of different size impact ELIC structure and that the nanodisc scaffold directly interacts with ELIC. These findings suggest that the nanodisc plays a crucial role in determining the structure of pLGICs, and that reconstitution of …

Fatty Acid Synthesis Suppresses Dietary Polyunsaturated Fatty Acid Use, Anna Worthmann, Sangeeta Adak, Clay F Semenkovich, Et Al.

2020-Current year OA Pubs

Dietary polyunsaturated fatty acids (PUFA) are increasingly recognized for their health benefits, whereas a high production of endogenous fatty acids - a process called de novo lipogenesis (DNL) - is closely linked to metabolic diseases. Determinants of PUFA incorporation into complex lipids are insufficiently understood and may influence the onset and progression of metabolic diseases. Here we show that fatty acid synthase (FASN), the key enzyme of DNL, critically determines the use of dietary PUFA in mice and humans. Moreover, the combination of FASN inhibition and PUFA-supplementation decreases liver triacylglycerols (TAG) in mice fed with high-fat diet. Mechanistically, FASN inhibition …

2020-Current year OA Pubs

BACKGROUND: Modern sequencing technologies offer extraordinary opportunities for virus discovery and virome analysis. Annotation of viral sequences from metagenomic data requires a complex series of steps to ensure accurate annotation of individual reads and assembled contigs. In addition, varying study designs will require project-specific statistical analyses.

FINDINGS: Here we introduce Hecatomb, a bioinformatic platform coordinating commonly used tasks required for virome analysis. Hecatomb means "a great sacrifice." In this setting, Hecatomb is "sacrificing" false-positive viral annotations using extensive quality control and tiered-database searches. Hecatomb processes metagenomic data obtained from both short- and long-read sequencing technologies, providing annotations to individual sequences …

Injectable Hydrogel Electrodes As Conduction Highways To Restore Native Pacing, Gabriel J Rodriguez-Rivera, Allison Post, Mathews John, Skylar Buchan, Drew Bernard, Mehdi Razavi, Elizabeth Cosgriff-Hernandez

Faculty, Staff and Students Publications

There is an urgent clinical need for a treatment regimen that addresses the underlying pathophysiology of ventricular arrhythmias, the leading cause of sudden cardiac death. The current report describes the design of an injectable hydrogel electrode and successful deployment in a pig model with access far more refined than any current pacing modalities allow. In addition to successful cardiac capture and pacing, analysis of surface ECG tracings and three-dimensional electroanatomic mapping revealed a QRS morphology comparable to native sinus rhythm, strongly suggesting the hydrogel electrode captures the deep septal bundle branches and Purkinje fibers. In an ablation model, electroanatomic mapping …

The Impact Of Race And Skin Color On Police Contact And Arrest: Results From A Nationally Representative Longitudinal Study, Michael F. Teneyck, Sarah A. El Sayed, Clay M. Driscoll, Krysta N. Knox

SAGE Open Access Agreement Publications-Archive

Racial inequality in arrest is a social problem that has challenged the United States for as long as police records have been kept. Prior work documents the extent of the disparity and observational studies have attempted to sort out the mechanisms that explain why the disparity exists. Building on the “constructivist” perspective of race, the current study draws on data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to assess the degree to which race and skin color explain the observed racial disparity in criminal justice contact and arrest. Results revealed that controlling for criminal behavior …

A Critical Reflection On The Importance Of Education For Sustainable Development, Daniel Kamphambale, Lucia Morales, Cormac H. Macmahon, Jon-Hans Coetzer

Irish Journal of Academic Practice

The United Nations (UN) 2030 Agenda and Sustainable Development highlights the value of the Sustainable Development Goals (SDGs) in enabling societal progress. Contemporary society needs to consider sustainable development in a broader context where equity, diversity, and inclusion are integral to design of educational systems. Education can act as a disruptor that brings change to existing economic growth models misaligned with the needs and demands of modern society. As we transition to economic models that are more attuned to the needs of global society and planet, access to education, natural resources, and human talent is crucial for sustaining development, and …

Combinatorial Effects Of Ion Channel Mis-Splicing As A Cause Of Myopathy In Myotonic Dystrophy, Larissa Nitschke, Thomas A Cooper

Faculty, Staff and Students Publications

Myotonic dystrophy type 1 (DM1) is an autosomal dominant disorder caused by an unstable expanded CTG repeat located in the 3'-UTR of the DM1 protein kinase (DMPK) gene. The pathogenic mechanism results in misregulated alternative splicing of hundreds of genes, creating the dilemma of establishing which genes contribute to the mechanism of DM1 skeletal muscle pathology. In this issue of the JCI, Cisco and colleagues systematically tested the combinatorial effects of DM1-relevant mis-splicing patterns in vivo and identified the synergistic effects of mis-spliced calcium and chloride channels as a major contributor to DM1 skeletal muscle impairment. The authors further demonstrated …

Conserved Residues At The Mtr4 C-Terminus Coordinate Helicase Activity And Exosome Interactions, Matthew K Yim, Catherine J Stuart, Markell I Pond, Ambro Van Hoof, Sean J Johnson

Faculty, Staff and Student Publications

Mtr4 is an essential RNA helicase involved in nuclear RNA processing and degradation and is a member of the Ski2-like helicase family. Ski2-like helicases share a common core architecture that includes two RecA-like domains, a winged helix, and a helical bundle (HB) domain. In Mtr4, a short C-terminal tail immediately follows the HB domain and is positioned at the interface of the RecA-like domains. The tail ends with a SLYΦ sequence motif that is highly conserved in a subset of Ski2-like helicases. Here, we show that this sequence is critical for Mtr4 function. Mutations in the C-terminus result in decreased …

Microbial Co-Occurrences On Catheters From Long-Term Catheterized Patients, Taylor M Nye, Zongsen Zou, Chloe L P Obernuefemann, Jerome S Pinkner, Erin Lowry, Kent Kleinschmidt, Karla Bergeron, Aleksandra Klim, Karen W Dodson, Ana L Flores-Mireles, Jennifer N Walker, Daniel Garrett Wong, Alana Desai, Michael G Caparon, Scott J Hultgren

2020-Current year OA Pubs

Catheter-associated urinary tract infections (CAUTIs), a common cause of healthcare-associated infections, are caused by a diverse array of pathogens that are increasingly becoming antibiotic resistant. We analyze the microbial occurrences in catheter and urine samples from 55 human long-term catheterized patients collected over one year. Although most of these patients were prescribed antibiotics over several collection periods, their catheter samples remain colonized by one or more bacterial species. Examination of a total of 366 catheter and urine samples identify 13 positive and 13 negative genus co-occurrences over 12 collection periods, representing associations that occur more or less frequently than expected …

A Dataset Of Digital Holograms Of Normal And Thalassemic Cells, Vahid Abbasian, Arash Darafsheh

2020-Current year OA Pubs

Digital holographic microscopy (DHM) is an intriguing medical diagnostic tool due to its label-free and quantitative nature, providing high-contrast images of phase samples. By capturing both intensity and phase information, DHM enables the numerical reconstruction of quantitative phase images. However, the lateral resolution is limited by the diffraction limit, which prompted the recent suggestion of microsphere-assisted DHM to enhance the DHM resolution straightforwardly. The use of such a technique as a medical diagnostic tool requires testing and validation of the proposed assays to prove their feasibility and viability. This paper publishes 760 and 609 microsphere-assisted DHM images of normal and …

Subnational Probabilistic Projections Of Fertility: Rethinking From Latin America, Lucia Andreozzi

Journal of Demography

General trends in fertility, mortality, and migration can be discerned and projected into the future with reasonable results, however, there is considerable uncertainty attached to each specific trend from a particular country or region. Then, subnational projections then represent a special chapter within the demographic projections. After introducing subnational projections and its close relationship with the fertility, this work proposes as the main objective to project fertility rates at the subnational level for Argentina using a probabilistic method; the bayesian hierarchical model (BHM), and then compare the results with the point estimates of deterministic projections published by the national organism …

Mcdonald Generalized Power Weibull Distribution: Properties, And Applications, Shei B. Sayibu, A. Luguterah, A. Luguterah, S. Nasiru

Journal of Statistics Applications & Probability

This research introduces a novel six-parameter model called the McDonald Generalized Power Weibull distribution. The model contains several sub-models that prove highly valuable in modeling real-life scenarios, including the McDonald Weibull, McDonald exponential, McDonald Nadarajah-Haghighi, beta generalized power Weibull distribution, and Kumaraswamy generalized power distributions, among others. The proposed model demonstrates suitability in modeling survival/reliability data, accommodating various hazard failure rates such as increasing, decreasing, unimodal (upside-down bathtub), modified bathtub, and reversed J-shape. Various properties of the new model are investigated, including moments, quantiles, incomplete moments, moment-generating functions, and order statistics. The maximum likelihood estimation method is employed to estimate …

Time Scale Theory On Stability Of Explicit And Implicit Discrete Epidemic Models: Applications To Swine Flu Outbreak, Gülşah Yeni, Elvan Akın, Naveen K. Vaidya

Mathematics and Statistics Faculty Research & Creative Works

Time scales theory has been in use since the 1980s with many applications. Only very recently, it has been used to describe within-host and between-hosts dynamics of infectious diseases. In this study, we present explicit and implicit discrete epidemic models motivated by the time scales modeling approach. We use these models to formulate the basic reproduction number, which determines whether an outbreak occurs, or the disease dies out. We discuss the stability of the disease-free and endemic equilibrium points using the linearization method and Lyapunov function. Furthermore, we apply our models to swine flu outbreak data to demonstrate that the …

Measuring Paranormal Beliefs: Reconceptualization And Empirical Validation Of The Paranormal Belief Construct, Hugo Matas, Enric Munar, Lluis Ballester, Maria José Hernández-Lloreda

International Journal of Transpersonal Studies Advance Publication Archive

The Revised Paranormal Belief Scale (RPBS) is the most widely-used tool for measuring beliefs in paranormal phenomena, although it is not free from criticism. Lindeman and Aarnio (2006) proposed an extended version of the RPBS with some improvements and a second-order hierarchical model to explain the structure of the scale. Our objective was to analyze the goodness of fit of the model and measurement invariance by sex in a Spanish sample. A sample of 6,584 participants completed the extended RPBS. After reversed items were removed, the model demonstrated an adequate fit, significant factor loadings and invariance between sexes. The results …
