Co-Delivery Of Therapeutics And Bioactive Gas Using A Novel Liposomal Platform For Enhanced Treatment Of Acute Arterial Injury, Shao-Ling Huang, Melanie R Moody, Xing Yin, David D Mcpherson, Hyunggun Kim

Faculty, Staff and Student Publications

Atherosclerosis is a complex, multi-stage disease characterized by pathological changes across the vascular wall. Endothelial dysfunction, inflammation, hypoxia, and vascular smooth muscle cell proliferation contribute to its progression. An effective strategy capable of delivering pleiotropic treatment to the vascular wall is essential to limit neointimal formation. Echogenic liposomes (ELIP), which can encapsulate bioactive gases and therapeutic agents, have the potential to deliver enhanced penetration and treatment efficacy for atherosclerosis. In this study, liposomes loaded with nitric oxide (NO) and rosiglitazone, a peroxisome proliferator-activated receptor agonist, were prepared using hydration, sonication, freeze-thawing, and pressurization. The efficacy of this delivery system was …

Faculty, Staff and Student Publications

OBJECTIVE: We aimed to develop a distributed, immutable, and highly available cross-cloud blockchain system to facilitate federated data analysis activities among multiple institutions.

MATERIALS AND METHODS: We preprocessed 9166 COVID-19 Structured Query Language (SQL) code, summary statistics, and user activity logs, from the GitHub repository of the Reliable Response Data Discovery for COVID-19 (R2D2) Consortium. The repository collected local summary statistics from participating institutions and aggregated the global result to a COVID-19-related clinical query, previously posted by clinicians on a website. We developed both on-chain and off-chain components to store/query these activity logs and their associated queries/results on a blockchain …

Whole-Exome Sequencing Study Of Hypospadias, Zhongzhong Chen, Yunping Lei, Richard H Finnell, Yu Ding, Zhixi Su, Yaping Wang, Hua Xie, Fang Chen

Faculty, Staff and Students Publications

Hypospadias results from the impaired urethral development, which is influenced by androgens, but its genetic etiology is still unknown. Through whole exome sequencing analysis, we identified NR5A1, SRD5A2, and AR as mutational hotspots in the etiology of severe hypospadias, as these genes are related to androgen signaling. Additionally, rare damaging variants in cilia-related outer dynein arm heavy chain (ODNAH) genes (DNAH5, DNAH8, DNAH9, DNAH11, and DNAH17) (p = 8.5 × 10−47) were significantly enriched in hypospadias cases. The Dnah8 KO mice exhibited significantly decreased testosterone levels, which had an impact on …

Mass Spectrometry Imaging Reveals Abnormalities In Cardiolipin Composition And Distribution In Astrocytoma Tumor Tissues, Anna C Krieger, Luis A Macias, J Clay Goodman, Jennifer S Brodbelt, Livia S Eberlin

Faculty, Staff and Students Publications

Cardiolipin (CL) is a mitochondrial lipid with diverse roles in cellular respiration, signaling, and organelle membrane structure. CL content and composition are essential for proper mitochondrial function. Deranged mitochondrial energy production and signaling are key components of glial cell cancers and altered CL molecular species have been observed in mouse brain glial cell xenograft tumors. The objective of this study was to describe CL structural diversity trends in human astrocytoma tumors of varying grades and correlate these trends with histological regions within the heterogeneous astrocytoma microenvironment. To this aim, we applied desorption electrospray ionization coupled with high field asymmetric ion …

Joint Effect Of Human Papillomavirus Exposure, Smoking And Alcohol On Risk Of Oral Squamous Cell Carcinoma, Zheng Yang, Peng Sun, Kristina R Dahlstrom, Neil Gross, Guojun Li

Faculty, Staff and Students Publications

BACKGROUND: Smoking, alcohol consumption, and human papillomavirus (HPV) infection are known risk factors for oral squamous cell carcinoma (OSCC) including SCC of oropharynx (SCCOP) and SCC of oral cavity (SCCOC). Researchers have examined each of these risk factors independently, but few have observed the potential risk of their interaction. This study investigated the interactions among these risk factors and risk of OSCC.

METHODS: Totally 377 patients with newly diagnosed SCCOP and SCCOC and 433 frequency-matched cancer-free controls by age and sex were included. Multivariable logistic regression was performed to calculate ORs and 95% CIs.

RESULTS: We found that overall OSCC …

Evaluating The Baseline Hemoglobin, Albumin, Lymphocyte, And Platelet (Halp) Score In The United States Adult Population And Comorbidities: An Analysis Of The Nhanes, Ryan Antar, Christian Farag, Vincent Xu, Arthur Drouaud, Olivia Gordon, Michael J. Whalen

Urology Faculty Publications

Introduction: As a composite immunonutritional biomarker, the Hemoglobin, Albumin, Lymphocyte, Platelet (HALP) score has shown promise in assessing a patient's overall health status by integrating several routinely collected laboratory indicators. This biomarker has been examined in many different populations of patients and disease states (i.e., cancer), but an integrated, universal rubric using standardized thresholds has not thus far been developed. Pre-existing large population-based databases represent an ideal source to examine the distribution of HALP and the influence of diverse health statuses on this score.

Methods: We conducted a cross-sectional study using data from the National Health and Nutrition Examination Survey …

Influenza C And D Viruses Demonstrated A Differential Respiratory Tissue Tropism In A Comparative Pathogenesis Study In Guinea Pigs, Chithra C. Sreenivasan, Runxia Liu, Rongyuan Gao, Yicheng Guo, Ben M. Hause, Milton Thomas, Ahsan Naveed, Travis Clement, Dana Rausch, Jane Christopher-Hennings, Eric Nelson, Julian Druce, Miaoyun Zhao, Radhey S. Kaushik, Qingsheng Li, Zizhang Sheng, Dan Dan, Feng Li

Nebraska Center for Virology: Faculty Publications

Influenza C virus (ICV) is increasingly associated with community-acquired pneumonia (CAP) in children and its disease severity is worse than the influenza B virus, but similar to influenza A virus associated CAP. Despite the ubiquitous infection landscape of ICV in humans, little is known about its replication and pathobiology in animals. The goal of this study was to understand the replication kinetics, tissue tropism, and pathogenesis of human ICV (huICV) in comparison to the swine influenza D virus (swIDV) in guinea pigs. Intranasal inoculation of both viruses did not cause clinical signs, however, the infected animals shed virus in nasal …

Treatment Of Angular Deformity And Limb Length Discrepancy With A Retrograde Femur Magnetic Intramedullary Nail: A Fixator-Assisted, Blocking Screw Technique, Erik J. Geiger, Adam D Geffner, S Robert Rozbruch, Austin T Fragomen

Rothman Institute Papers

Background: Fixator-assisted nailing techniques that incorporate magnetic internal lengthening nails (MILNs) permit acute deformity correction and then gradual limb lengthening without needing postoperative external fixators.

Purposes: We sought to investigate the safety and accuracy of a fixator-assisted, blocking screw technique using retrograde MILNs for the correction of LLD and limb malalignment.

Methods: Forty-one patients (13 patients with genu varum and 28 patients with genu valgum) with LLD treated with fixator-assisted, blocking screw retrograde MILN reconstruction were included. Preoperative LLD, mechanical axis deviation, and joint orientation angles were compared with values at the end of treatment, and bone healing indices were …

Guaranteed Income And Financial Treatment Trial (Gift Trial Or Giftt): A 12-Month, Randomized Controlled Trial To Compare The Effectiveness Of Monthly Unconditional Cash Transfers To Treatment As Usual In Reducing Financial Toxicity In People With Cancer Who Have Low Incomes, Meredith Doherty, Jonathan Heintz, Amy Leader, David Wittenburg, Yonatan Ben-Shalom, Jessica Jacoby, Amy Castro, Stacia West

Department of Medical Oncology Faculty Papers

Cancer-related financial hardship (i.e., financial toxicity) has been associated with anxiety and depression, greater pain and symptom burden, treatment nonadherence, and mortality. Out-of-pocket healthcare costs and lost income are primary drivers of financial toxicity, however, income loss is a pronounced risk factor for cancer patients with low incomes. There has been little progress in developing an income intervention to alleviate financial toxicity cancer patients with low incomes. Unconditional cash transfers (UCT), or guaranteed income, have produced positive health effects in experiments with general low-income populations, but have not yet been evaluated in people with cancer. The Guaranteed Income and Financial …

Single-Frame Deep-Learning Super-Resolution Microscopy For Intracellular Dynamics Imaging, Rong Chen, Xiao Tang, Yuxuan Zhao, Zeyu Shen, Meng Zhang, Yusheng Shen, Tiantian Li, Casper Ho Yin Chung, Lijuan Zhang, Ji Wang, Binbin Cui, Peng Fei, Yusong Guo, Shengwang Du, Shuhuai Yao

Faculty, Staff and Student Publications

Single-molecule localization microscopy (SMLM) can be used to resolve subcellular structures and achieve a tenfold improvement in spatial resolution compared to that obtained by conventional fluorescence microscopy. However, the separation of single-molecule fluorescence events that requires thousands of frames dramatically increases the image acquisition time and phototoxicity, impeding the observation of instantaneous intracellular dynamics. Here we develop a deep-learning based single-frame super-resolution microscopy (SFSRM) method which utilizes a subpixel edge map and a multicomponent optimization strategy to guide the neural network to reconstruct a super-resolution image from a single frame of a diffraction-limited image. Under a tolerable signal density and …

Pou4f1-Tbr1 Transcriptional Cascade Controls The Formation Of Jam2-Expressing Retinal Ganglion Cells, Takae Kiyama, Halit Y Altay, Tudor C Badea, Chai-An Mao

Faculty, Staff and Student Publications

More than 40 retinal ganglion cell (RGC) subtypes have been categorized in mouse based on their morphologies, functions, and molecular features. Among these diverse subtypes, orientation-selective Jam2-expressing RGCs (J-RGCs) has two unique morphologic characteristics: the ventral-facing dendritic arbor and the OFF-sublaminae stratified terminal dendrites in the inner plexiform layer. Previously, we have discovered that T-box transcription factor T-brain 1 (Tbr1) is expressed in J-RGCs. We further found that Tbr1 is essential for the expression of Jam2, and Tbr1 regulates the formation and the dendritic morphogenesis of J-RGCs. However, Tbr1 begins to express in terminally differentiated RGCs around …

Cxcl8/Cxcr2 Signaling Mediates Bone Marrow Fibrosis And Is A Therapeutic Target In Myelofibrosis, Andrew J Dunbar, Dongjoo Kim, Min Lu, Mirko Farina, Robert L Bowman, Julie L Yang, Young Park, Abdul Karzai, Wenbin Xiao, Zach Zaroogian, Kavi O'Connor, Shoron Mowla, Francesca Gobbo, Paola Verachi, Fabrizio Martelli, Giuseppe Sarli, Lijuan Xia, Nada Elmansy, Maria Kleppe, Zhuo Chen, Yang Xiao, Erin Mcgovern, Jenna Snyder, Aishwarya Krishnan, Corrine Hill, Keith Cordner, Anouar Zouak, Mohamed E Salama, Jayden Yohai, Eric Tucker, Jonathan Chen, Jing Zhou, Timothy Mcconnell, Anna R Migliaccio, Richard Koche, Raajit Rampal, Rong Fan, Ross L Levine, Ronald Hoffman

Proinflammatory signaling is a hallmark feature of human cancer, including in myeloproliferative neoplasms (MPNs), most notably myelofibrosis (MF). Dysregulated inflammatory signaling contributes to fibrotic progression in MF; however, the individual cytokine mediators elicited by malignant MPN cells to promote collagen-producing fibrosis and disease evolution are yet to be fully elucidated. Previously, we identified a critical role for combined constitutive JAK/STAT and aberrant NF-κB proinflammatory signaling in MF development. Using single-cell transcriptional and cytokine-secretion studies of primary cells from patients with MF and the human MPLW515L (hMPLW515L) murine model of MF, we extend our previous work and delineate the role of …

Morphology Of The Ventral Process Of The Sixth Cervical Vertebra In Extinct And Extant Equus: Functional Implications, Sharon May-Davis, Robert Hunter, Richard White

Faculty, Staff and Student Publications

In this study, we examined the ventral process of C6 in extinct and extant Equus (sister taxa to Equus ferus caballus only) with the purpose of describing normal morphology and identifying anomalous variations relevant to recent studies describing a congenital malformation in E. ferus caballus. Overall, 83 specimens from 9 museums and 3 research/educational facilities were examined, totalling 71 extinct specimens from 12 species and 12 extant specimens from 5 species. The lateral view revealed that a large convexity exists in the ventral process between the cranial ventral tubercle (CrVT) and the caudal ventral tubercle (CVT) in the earliest …

Respondents included patients (n=141) who consulted a fertility specialist in the previous 2 years, and fertility nurses (n=80) who assisted in at least 75 ART cycles/year. Patients were divided into two subgroups depending on their experience with ART (experienced and naïve). Key attributes for an injection …

Deciphering Tumor Ecosystems At Super Resolution From Spatial Transcriptomics With Tesla, Jian Hu, Kyle Coleman, Daiwei Zhang, Edward B Lee, Humam Kadara, Linghua Wang, Mingyao Li

Faculty, Staff and Student Publications

Cell populations in the tumor microenvironment (TME), including their abundance, composition, and spatial location, are critical determinants of patient response to therapy. Recent advances in spatial transcriptomics (ST) have enabled the comprehensive characterization of gene expression in the TME. However, popular ST platforms, such as Visium, only measure expression in low-resolution spots and have large tissue areas that are not covered by any spots, which limits their usefulness in studying the detailed structure of TME. Here, we present TESLA, a machine learning framework for tissue annotation with pixel-level resolution in ST. TESLA integrates histological information with gene expression to annotate …

A Rare Cause Of Lymphadenopathy In A Young Hispanic Female: Unmasking Recurrent Nodal Rosai-Dorfman Disease, Blesset Alexander, Alfarooq Alshaikhli, Mery Bartl, Emilia Dulgheru

School of Medicine Publications

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder that can present with painless bilateral symmetrical cervical lymphadenopathy, mimicking lymphomas. RDD is characterized by excessive tissue infiltration by dendritic cells, macrophages, or monocyte-derived cells, with a histopathologic diagnosis based on the presence of CD68+, CD163+, and S100+ histiocytes, which differentiate it from other histiocytic neoplasms. In this case report, we present a young Hispanic female with recurrent subcutaneous growths and lymphadenopathy, initially thought to be lymphoma, who was diagnosed with RDD after a significant diagnostic workup. Treatment initially consisted of surgical excision; however, due to recurrence, the patient was successfully treated …

The Child Healthcare At Mater Pediatric Study (Champs): A 2-Arm Cluster Randomized Control Trial Of Group Well Child Care For Mothers In Treatment For Opioid Use Disorder And Their Children, Vanessa L. Short, Diane J. Abatemarco, Erica Sood, Dennis J. Hand, Meghan Gannon, Jobayer Hossain, Neera K. Goyal

Department of Pediatrics Faculty Papers

BACKGROUND: Studies suggest that group-based well child care-a shared medical appointment where families come together as a group to receive pediatric primary care-increases patient-reported satisfaction and adherence to recommended care. Evidence supporting the use of group well child care for mothers with opioid use disorder, however, is lacking. The overall objective of the Child Healthcare at MATER Pediatric Study (CHAMPS) trial is to evaluate a group model of well child care for mothers with opioid use disorder and their children.

METHODS: CHAMPS is a single-site 2-arm cluster randomized controlled trial. A total of 108 mother-child dyads will be enrolled into …

Faculty, Staff and Students Publications

Though the formation of neutralizing antibodies (NAbs) during treatment with botulinum neurotoxin is rare, their presence may nonetheless affect the biological activity of botulinum toxin and negatively impact clinical response. The goal of this updated meta-analysis was to evaluate and characterize the rate of NAb formation using an expanded dataset composed of 33 prospective placebo-controlled and open-label clinical trials with nearly 30,000 longitudinal subject records prior to and following onabotulinumtoxinA treatment in 10 therapeutic and aesthetic indications. Total onabotulinumtoxinA doses per treatment ranged from 10 U to 600 U administered in ≤15 treatment cycles. The NAb formation at baseline and …
