Myeloid-Associated Differentiation Marker Is Associated With Type 2 Asthma And Is Upregulated By Human Rhinovirus Infection, Sasipa Tanyaratsrisakul, Alane Blythe C Dy, Francesca Polverino, Mari Numata, Julie G Ledford

Faculty, Staff and Students Publications

BACKGROUND: Human rhinoviruses are known to predispose infants to asthma development during childhood and are often associated with exacerbations in asthma patients. MYADM epithelial expression has been shown to associate with asthma severity. The goal of this study was to determine if MYADM expression patterns were altered in asthma and/or rhinovirus infection and if increased MYADM expression is associated with increased asthma-associated factors.

METHODS: Utilizing H1HeLa cells and differentiated primary human airway epithelial cells (AECs), we measured the expression of MYADM and inflammatory genes by qRT-PCR in the presence or absence of RV-1B infection or poly I:C treatment and with …

Emerging Challenges To Cellular Therapy Of Cancer, Premal D Lulla, Malcolm Brenner

Faculty, Staff and Students Publications

Cellular immunotherapy of cancer in the form of chimeric antigen receptor-modified T-cell therapy has become a standard treatment for lymphoid and more recently plasma cell malignancies. Although their successes in these cancers represent a breakthrough for adoptive cell therapy, there are several challenges to their continued growth in the field of cancer medicine. In this review, we discuss the progress made thus far toward achieving "off-the-shelf" accessibility of cell therapies that has the potential to greatly offset the costs associated with the current practice of making patient-specific products. We also review the innovations under investigation that attempt to make cellular …

Effective de-implementation models often include replacement of an ineffective practice with an alternative. We co-developed patient education materials as a replacement strategy for inappropriate post-procedural antibiotics in cardiac device procedures. Lessons learned and developed materials may be used to promote infection prevention in other periprocedural settings.

Differential Regulation Of Skeletal Stem/Progenitor Cells In Distinct Skeletal Compartments, Jea Giezl Niedo Solidum, Youngjae Jeong, Francisco Heralde, Dongsu Park

Faculty, Staff and Students Publications

Skeletal stem/progenitor cells (SSPCs), characterized by self-renewal and multipotency, are essential for skeletal development, bone remodeling, and bone repair. These cells have traditionally been known to reside within the bone marrow, but recent studies have identified the presence of distinct SSPC populations in other skeletal compartments such as the growth plate, periosteum, and calvarial sutures. Differences in the cellular and matrix environment of distinct SSPC populations are believed to regulate their stemness and to direct their roles at different stages of development, homeostasis, and regeneration; differences in embryonic origin and adjacent tissue structures also affect SSPC regulation. As these SSPC …

Selective Reprogramming Of Regulatory T Cells In Solid Tumors Can Strongly Enhance Or Inhibit Tumor Growth, Rami Alfar, John V Napoleon, Imrul Shahriar, Richard Finnell, Cole Walchle, Austin Johnson, Philip S Low

Faculty, Staff and Students Publications

Folate receptor delta (FRδ) has been used as a biomarker for regulatory T cells (Tregs), because its expression is limited to Tregs and ovum. Although FRδ is unable to bind folate, we have used molecular docking software to identify a folate congener that binds FRδ with high affinity and have exploited this FRδ-specific ligand to target attached drugs (imaging agents, immune activators, and immune suppressors) specifically to Tregs in murine tumor xenografts. Analysis of treated tumors demonstrates that targeting of a Toll-like receptor 7 agonist inhibits Treg expression of FOXP3, PD-1, CTLA4, and HELIOS, resulting in 40-80% reduction in tumor …

A Novel Interaction Between Extracellular Vimentin And Fibrinogen In Fibrin Formation, Marina Martinez-Vargas, Adrian Cebula, Lisa S Brubaker, Nitin Seshadri, Fong W Lam, Michele Loor, Todd K Rosengart, Andrew Yee, Rolando E Rumbaut, Miguel A Cruz

Faculty, Staff and Students Publications

INTRODUCTION: Thrombosis is frequently manifested in critically ill patients with systemic inflammation, including sepsis and COVID-19. The coagulopathy in systemic inflammation is often associated with increased levels of fibrinogen and D-dimer. Because elevated levels of vimentin have been detected in sepsis, we sought to investigate the relationship between vimentin and the increased fibrin formation potential observed in these patients.

MATERIALS AND METHODS: This hypothesis was examined by using recombinant human vimentin, anti-vimentin antibodies, plasma derived from healthy and critically ill patients, confocal microscopy, co-immunoprecipitation assays, and size exclusion chromatography.

RESULTS: The level of vimentin in plasma derived from critically ill …

Peptidylarginine Deiminase 2 Citrullinates Mzb1 And Promotes The Secretion Of Igm And Iga, Benjamin Geary, Bo Sun, Ronak R Tilvawala, Leonard Barasa, Konstantin Tsoyi, Ivan O Rosas, Paul R Thompson, I-Cheng Ho

Faculty, Staff and Students Publications

INTRODUCTION: MZB1 is an endoplasmic reticulum residential protein preferentially expressed in plasma cells, marginal zone and B1 B cells. Recent studies on murine B cells show that it interacts with the tail piece of IgM and IgA heavy chain and promotes the secretion of these two classes of immunoglobulin. However, its role in primary human B cells has yet to be determined and how its function is regulated is still unknown. The conversion of peptidylarginine to peptidylcitrulline, also known as citrullination, by peptidylarginine deiminases (PADs) can critically influence the function of proteins in immune cells, such as neutrophils and T …

Cell-Type-Specific Aging Clocks To Quantify Aging And Rejuvenation In Neurogenic Regions Of The Brain, Matthew T Buckley, Eric D Sun, Benson M George, Ling Liu, Nicholas Schaum, Lucy Xu, Jaime M Reyes, Margaret A Goodell, Irving L Weissman, Tony Wyss-Coray, Thomas A Rando, Anne Brunet

Faculty, Staff and Students Publications

The diversity of cell types is a challenge for quantifying aging and its reversal. Here we develop 'aging clocks' based on single-cell transcriptomics to characterize cell-type-specific aging and rejuvenation. We generated single-cell transcriptomes from the subventricular zone neurogenic region of 28 mice, tiling ages from young to old. We trained single-cell-based regression models to predict chronological age and biological age (neural stem cell proliferation capacity). These aging clocks are generalizable to independent cohorts of mice, other regions of the brains, and other species. To determine if these aging clocks could quantify transcriptomic rejuvenation, we generated single-cell transcriptomic datasets of neurogenic …

The AURORA US Metastasis Project was established with the goal to identify molecular features associated with metastasis. We assayed 55 females with metastatic breast cancer (51 primary cancers and 102 metastases) by RNA sequencing, tumor/germline DNA exome and low-pass whole-genome sequencing and global DNA methylation microarrays. Expression subtype changes were observed in ~30% of samples and were coincident with DNA clonality shifts, especially involving HER2. Downregulation of estrogen receptor (ER)-mediated cell-cell adhesion genes through DNA methylation mechanisms was observed in metastases. Microenvironment differences varied according to tumor subtype; the ER

Alveolar Macrophages In Lung Cancer: Opportunities Challenges, Cheng-Yen Chang, Dominique Armstrong, David B Corry, Farrah Kheradmand

Faculty, Staff and Students Publications

Alveolar macrophages (AMs) are critical components of the innate defense mechanism in the lung. Nestled tightly within the alveoli, AMs, derived from the yolk-sac or bone marrow, can phagocytose foreign particles, defend the host against pathogens, recycle surfactant, and promptly respond to inhaled noxious stimuli. The behavior of AMs is tightly dependent on the environmental cues whereby infection, chronic inflammation, and associated metabolic changes can repolarize their effector functions in the lungs. Several factors within the tumor microenvironment can re-educate AMs, resulting in tumor growth, and reducing immune checkpoint inhibitors (ICIs) efficacy in patients treated for non-small cell lung cancer …

As the COVID-19 pandemic continues into its third year, emerging data indicates increased risks associated with SARS-CoV-2 infection during pregnancy, including pre-eclampsia, intrauterine growth restriction, preterm birth, stillbirth, and risk of developmental defects in neonates. Here, we review clinical reports to date that address different COVID-19 pregnancy complications. We also document placental pathologies induced by SARS-CoV-2 infection, entry mechanisms in placental cells, and immune responses at the maternal-fetal interface. Since new variants of SARS-CoV-2 are emerging with characteristics of higher transmissibility and more effective immune escape strategies, we also briefly highlight the genomic and proteomic features of SARS-CoV-2 investigated to …

Combining Charlson Comorbidity And Vacs Indices Improves Prognostic Accuracy For All-Cause Mortality For Patients With And Without Hiv In The Veterans Health Administration, Kathleen A Mcginnis, Amy C Justice, Vincent C Marconi, Maria C Rodriguez-Barradas, Ronald G Hauser, Krisann K Oursler, Sheldon T Brown, Kendall J Bryant, Janet P Tate, Veterans Aging Cohort Study Affiliations

Faculty, Staff and Students Publications

INTRODUCTION: As people age with HIV (PWH), many comorbid diseases are more common than among age matched comparators without HIV (PWoH). While the Veterans Aging Cohort (VACS) Index 2.0 accurately predicts mortality in PWH using age and clinical biomarkers, the only included comorbidity is hepatitis C. We asked whether adding comorbid disease groupings from the Charlson Comorbidity Index (CCI) improves the accuracy of VACS Index.

METHODS: To maximize our ability to model mortality among older age groups, we began with PWoH in Veterans Health Administration (VA) from 2007-2017, divided into development and validation samples. Baseline predictors included age, and components …

The Pathway To The Natural Gas Industry: Financial Development, Coal Consumption, And Carbon Dioxide Emissions In Pr China, Teng Tong, Jaime Ortiz, Haibo Wang

Faculty, Staff and Students Publications

This paper revisits the causal links between financial development, coal consumption, and CO2 emissions in P.R. China over the 1977–2017 period to validate the development of its natural gas industry. It uses a Bootstrap ARDL bound test with structural breaks to establish stationarity, short- and long-run dynamics, and causality of the series. The results show there are no long-run relationships among these three variables, but a Granger causality test does indicate the presence of both a two-way Granger causality between coal consumption and CO2 emissions, and a one-way Granger causality running from financial development to both coal consumption and CO2 …

Guidelines For Evaluating Safety Using Traffic Encounters: Proactive Crash Estimation On Roadways With Conventional And Autonomous Vehicle Scenarios, Andrew P. Tarko, Mario A. Romero, Vamsi Krishna Bandaru, Xueqian Shi

JTRP Technical Reports

With the expected arrival of autonomous vehicles, and the ever-increasing levels of automation in today’s human driven vehicles, road safety is changing at a rapid pace. This project aimed to address the need for an efficient and rapid method of safety evaluation and countermeasure identification via traffic encounters, specifically traffic conflicts that are considered useful surrogates of crashes. Recent research-delivered methods for estimating crash frequencies based on these events were observed in the field. In this project we developed a method for observing traffic encounters with two LiDAR-based traffic monitoring units, called TScan, which were recently developed in JTRP-funded projects …

Native Bk Polyomavirus Nephropathy In An Orthotopic Heart Transplant Patient, Zachary M Thompson, George Ajene, Prathit A Kulkarni, Nidhi Aggarwal, Savitri Fedson, Maulin K Shah

Faculty, Staff and Students Publications

BK polyomavirus nephropathy (BKVN) is a common cause of nephropathy in kidney transplant patients and is typically seen within the first year after transplantation. BK polyomavirus nephropathy can occur in the native kidneys of patients with nonrenal solid-organ transplants (NRSOT). However, this is rare, especially outside the early post-transplant period, and BKVN is not usually considered in the differential diagnosis for acute kidney injury in NRSOT patients. We present a case of a 75-year-old man who had undergone orthotopic heart transplant 13 years prior with stable allograft function who developed progressive renal dysfunction in the setting of recent unilateral obstructive …

Cerebral Microdialysis And Glucopenia In Traumatic Brain Injury: A Review, Himanshu Sharma, John P Mcginnis, Katherine E Kabotyanski, Shankar P Gopinath, Jerry C Goodman, Claudia Robertson, Jovany Cruz Navarro

Faculty, Staff and Students Publications

Traditionally, intracranial pressure (ICP) and partial brain tissue oxygenation (PbtO2) have been the primary invasive intracranial measurements used to guide management in patients with severe traumatic brain injury (TBI). After injury however, the brain develops an increased metabolic demand which may require an increment in the oxidative metabolism of glucose. Simultaneously, metabolic, and electrical dysfunction can lead to an inability to meet these demands, even in the absence of ischemia or increased intracranial pressure. Cerebral microdialysis provides the ability to accurately measure local concentrations of various solutes including lactate, pyruvate, glycerol and glucose. Experimental and clinical data demonstrate that such …

High EV daily charging demand areas in Indiana were shown in ArcGIS based on multiple scenarios of different charging station …

Implementing Epoxy Injection In Concrete Overlaid Bridge Decks, Prince Baah

JTRP Technical Reports

Concrete overlays have proven to be an effective maintenance treatment as they slow de-icing chemical and water penetration into the original deck surface. Typically, due to vibration, structural flexibility, and weak bond between the concrete overlay and deck concrete potentially due to poor construction, de-bonding develops at the boundary between the original deck and overlay. This de-bonding creates voids, providing reservoir for chloride laden water to fill after it penetrates cracks in the surface. Displacing this liquid solution and filling these cracks with epoxy helps reduce freeze/thaw cycling and reduces spalling. The epoxy material protects the bridge deck from moisture …

Speed Management On Freeways In Transition Zones Between Rural And Urban Conditions, Raul A. Pineda-Mendez, Xueqian Shi, Andrew P. Tarko, Mario A. Romero

JTRP Technical Reports

Drivers’ noncompliance with the posted speed limit reductions on rural-to-urban freeway transition zones is a recurrent problem in Indiana and other states. Speed-reduction treatments, such as pavement markings and active signing, aim to solve this issue. Optical speed bars, longitudinal speed reduction markings, and speed feedback signs were identified as the most promising speed-reduction treatments for experimental implementation in Indiana. Probe-vehicle-based speed data for 1 year was acquired on selected freeway segments to measure the speed effect. A set of fixed-effects linear regression models were used to estimate the effect of speed-reduction treatments on three key speed behavior characteristics—average speed, …

Determining Optimal Traffic Opening Time Through Concrete Strength Monitoring: Wireless Sensing, Zhihao Kong, Na Lu

JTRP Technical Reports

Construction and concrete production are time-sensitive and fast-paced; as such, it is crucial to monitor the in-place strength development of concrete structures in real-time. Existing concrete strength testing methods, such as the traditional hydraulic compression method specified by ASTM C 39 and the maturity method specified by ASTM C 1074, are labor-intensive, time consuming, and difficult to implement in the field. INDOT’s previous research (SPR-4210) on the electromechanical impedance (EMI) technique has established its feasibility for monitoring in-situ concrete strength to determine the optimal traffic opening time. However, limitations of the data acquisition and communication systems have significantly hindered the …

Development Of A Multiple Water Course Joint Probability Analysis Procedure For Indiana Watersheds, Ankit Ghanghas, Sayan Dey, Venkatesh Merwade

JTRP Technical Reports

The design of hydraulic structures located near a confluence of two streams must take into consideration the flows from both of the streams. A hydraulic structure located on a small tributary that drains into a large river immediately downstream is not just affected by the flow in the tributary, but also by the backwater flow from the downstream river. Currently INDOT uses a tabular summary (Table 1.1 and Table 7.3 in the HEC-22 manual) of joint probabilities of coincident flows in designing hydraulic structures at confluences. However, the source of the table is unknown, and the tabular summary provides coincidental …

The Natural Resources Conservation Service (NRCS, formerly the Soil Conservation Service, SCS) unit hydrograph (UH) is one of the most commonly used synthetic UH methods for hydrologic modeling and engineering design all over the world. However, previous studies have shown that the application of the NRCS UH method for some ungauged watersheds in the state of Indiana produced unrealistic flood predictions for both the peak discharge and the time to peak. The objective of this work is to customize the NRCS UH by analyzing the role of its two key parameters, namely, the peak rate factor (PRF) and …

Assessment Of Pipe Fill Heights, Luz María Agudelo Urrego, Chatuphat Savigamin, Devansh Gandhi, Ghadir Haikal, Antonio Bobet

JTRP Technical Reports

The design of buried pipes, in terms of the allowable minimum and maximum cover heights, requires the use of both geotechnical and structural design procedures. The geotechnical procedure focuses on estimating the load on the pipe and the compressibility of the foundation soil. The focus of the structural design is choosing the correct cross-section details of the pipe under consideration. The uncertainties of the input parameters and installation procedures are significant. Because of that, the Load Resistance Factor Design (LRFD) method is considered to be suitable for the design of buried pipes. Furthermore, the interaction between the pipe structure and …

JTRP Technical Reports

During the lifecycle of a bridge, deterioration of the concrete deck originates from many sources, e.g., corrosion due to water infiltration in conjunction with chlorides from the use of de-icing salts. Such deterioration may be affected by any one of the following six actions relevant to a bridge from conception to demolition: design, construction, in-service conditions, maintenance, repair and rehabilitation, and replacement. Many researchers have studied the relationships between these sources and their consequences. However, the relationship between construction defects and inspection practices, and its impact on the deterioration process has not yet been identified. This project focuses on the …

Shear And Bearing Capacity Of Corroded Steel Beam Bridges And The Effects On Load Rating, Deven Kanakamedala, Jungil Seo, Amit H. Varma, Robert J. Connor, Anna Tarasova

JTRP Technical Reports

Corrosion in the girders of steel girder bridges often occurs due to the deicing salts, water, and other debris that leak through the deck joints into the web and bottom flange at the girder ends. Corrosion causes loss of cross-sectional area leading to a reduction in section properties of the member, which eventually results in a reduction in structural resistance against shear and bearing. In this study, seven full-scale tests were performed on decommissioned steel girders acquired from bridges scheduled for demolition in Indiana. Two of the four girders had severe corrosion with cracks and holes in the bottom of …
