© 2020, The Author(s). Vagus nerve stimulation (VNS) is a bioelectronic therapy for disorders of the brain and peripheral organs, and a tool to study the physiology of autonomic circuits. Selective activation of afferent or efferent vagal fibers can maximize efficacy and minimize off-target effects of VNS. Anodal block (ABL) has been used to achieve directional fiber activation in nerve stimulation. However, evidence for directional VNS with ABL has been scarce and inconsistent, and it is unknown whether ABL permits directional fiber activation with respect to functional effects of VNS. Through a series of vagotomies, we established physiological markers for …

Nanoformulation Of The Superoxide Dismutase Mimic, Mntnbuoe-2-Pyp5+, Prevents Its Acute Hypotensive Response, Sarah L. Schlichte, Svetlana Romanova, Kenichi Katsurada, Elizabeth A. Kosmacek, Tatiana K. Bronich, Kaushik K. Patel, Rebecca E. Oberley-Deegan, Matthew C. Zimmerman

Journal Articles: Cellular & Integrative Physiology

Scavenging superoxide (O₂^•-) via overexpression of superoxide dismutase (SOD) or administration of SOD mimics improves outcomes in multiple experimental models of human disease including cardiovascular disease, neurodegeneration, and cancer. While few SOD mimics have transitioned to clinical trials, MnTnBuOE-2-PyP⁵⁺ (BuOE), a manganese porphyrin SOD mimic, is currently in clinical trials as a radioprotector for cancer patients; thus, providing hope for the use of SOD mimics in the clinical setting. However, BuOE transiently alters cardiovascular function including a significant and precipitous decrease in blood pressure. To limit BuOE's acute hypotensive action, we developed a mesoporous silica nanoparticle …

Evidence Supporting The Use Of Peptides And Peptidomimetics As Potential Sars-Cov-2 (Covid-19) Therapeutics, S. Vanpatten, M. He, A. Altiti, K. F Cheng, M. H. Ghanem, Y. Al-Abed

Journal Articles

© 2020 Newlands Press. During a disease outbreak/pandemic situation such as COVID-19, researchers are in a prime position to identify and develop peptide-based therapies, which could be more rapidly and cost-effectively advanced into a clinical setting. One drawback of natural peptide drugs, however, is their proteolytic instability; peptidomimetics can help to overcome this caveat. In this review, we summarize peptide and peptide-based therapeutics that target one main entry pathway of SARS-CoV-2, which involves the host ACE2 receptor and viral spike (S) protein interaction. Furthermore, we discuss the advantages of peptidomimetics and other potential targets that have been studied using peptide-based …

© 2020 The Authors Women's health concerns are generally underrepresented in basic and translational research, but reproductive health in particular has been hampered by a lack of understanding of basic uterine and menstrual physiology. Menstrual health is an integral part of overall health because between menarche and menopause, most women menstruate. Yet for tens of millions of women around the world, menstruation regularly and often catastrophically disrupts their physical, mental, and social well-being. Enhancing our understanding of the underlying phenomena involved in menstruation, abnormal uterine bleeding, and other menstruation-related disorders will move us closer to the goal of personalized care. …

Soluble Urokinase Plasminogen Activator Receptor (Supar) Levels Predict Damage Accrual In Patients With Recent-Onset Systemic Lupus Erythematosus, H. Enocsson, L. Wirestam, C. Dahle, L. Padyukov, A. Jönsen, M. B. Urowitz, D. D. Gladman, C. Aranow, M. Mackay, C. Sjöwall, +36 Additional Authors

Journal Articles

© 2019 The Authors Objective: The soluble urokinase plasminogen activator receptor (suPAR) has potential as a prognosis and severity biomarker in several inflammatory and infectious diseases. In a previous cross-sectional study, suPAR levels were shown to reflect damage accrual in cases of systemic lupus erythematosus (SLE). Herein, we evaluated suPAR as a predictor of future organ damage in recent-onset SLE. Methods: Included were 344 patients from the Systemic Lupus International Collaborating Clinics (SLICC) Inception Cohort who met the 1997 American College of Rheumatology classification criteria with 5-years of follow-up data available. Baseline sera from patients and age- and sex-matched controls …

Immunological Significance Of Hmgb1 Post-Translational Modification And Redox Biology, M. S. Kwak, H. S. Kim, B. Lee, Y. H. Kim, M. Son, J. S. Shin

Journal Articles

© Copyright © 2020 Kwak, Kim, Lee, Kim, Son and Shin. Most extracellular proteins are secreted via the classical endoplasmic reticulum (ER)/Golgi-dependent secretion pathway; however, some proteins, including a few danger-associated molecular patterns (DAMPs), are secreted via non-classical ER/Golgi-independent secretion pathways. The evolutionarily conserved high mobility group box1 (HMGB1) is a ubiquitous nuclear protein that can be released by almost all cell types. HMGB1 lacks signal peptide and utilizes diverse non-canonical secretion mechanisms for its extracellular export. Although the post-translational modifications of HMGB1 were demonstrated, the oxidation of HMGB1 and secretion mechanisms are not highlighted yet. We currently investigated that …

A Cross-Disease Meta-Gwas Identifies Four New Susceptibility Loci Shared Between Systemic Sclerosis And Crohn’S Disease, D. González-Serna, E. Ochoa, E. López-Isac, A. Julià, F. Degenhardt, N. Ortego-Centeno, T. R. Radstake, P. K. Gregersen, A. T. Lee, A. Gabrielli, +78 Additional Authors

Journal Articles

© 2020, The Author(s). Genome-wide association studies (GWASs) have identified a number of genetic risk loci associated with systemic sclerosis (SSc) and Crohn’s disease (CD), some of which confer susceptibility to both diseases. In order to identify new risk loci shared between these two immune-mediated disorders, we performed a cross-disease meta-analysis including GWAS data from 5,734 SSc patients, 4,588 CD patients and 14,568 controls of European origin. We identified 4 new loci shared between SSc and CD, IL12RB2, IRF1/SLC22A5, STAT3 and an intergenic locus at 6p21.31. Pleiotropic variants within these loci showed opposite allelic effects in the two analysed diseases …

Perivascular Macrophages In The Neonatal Macaque Brain Undergo Massive Necroptosis After Simian Immunodeficiency Virus Infection, Diana G. Bohannon, Yueying Wang, Colin H. Reinhart, Julian B. Hattler, Jiangtao Luo, Hamid R. Okhravi, Jianshui Zhang, Qingsheng Li, Marcelo J. Kuroda, Woong-Ki Kim

Nebraska Center for Virology: Faculty Publications

We previously showed that rhesus macaques neonatally infected with simian immunodeficiency virus (SIV) do not develop SIV encephalitis (SIVE) and maintain low brain viral loads despite having similar plasma viral loads compared to SIV-infected adults. We hypothesize that differences in myeloid cell populations that are the known target of SIV and HIV in the brain contribute to the lack of neonatal susceptibility to lentivirus-induced encephalitis. Using immunohistochemistry and immunofluorescence microscopy, we examined the frontal cortices from uninfected and SIV-infected infant and adult macaques (n = 8/ea) as well as adults with SIVE (n = 4) to determine differences in myeloid …

How Partnerships For Community-Based Health Professions Training Were Affected By National Changes In Funding, Patricia A. Carney, Eric M. Wiser, Cynthia Taylor, Debbie Cole, Shelley Dougherty, Chris Gustaferro, Meredith Lair, Curt Stilp

Faculty Publications - College of Medical Science

Background: Area Health Education Centers (AHEC) have contributed to U.S. healthcare workforce training since 1971. National funders recently refocused efforts from K-12 students to matriculated health profession students, which reduced annual funding by $75,000 (25%) per year per Center.

Objectives: To describe how community partnership changed due to funding reductions.

Methods: Key informant interviews were conducted with all four regional center directors with community partnerships.

Lessons learned: Hosted regional centers navigated partnerships in ways that did not significantly change programs because the host institutions supported continuing the partnerships. Independent centers experienced significant changes in partnerships by ending well-established programs and …

Sars-Cov-2 And Interferon Blockade, B. Diamond, B. T. Volpe, S. Van Patten, Y. Al Abed

Journal Articles

© 2020, The Author(s). The response to viral infection generally includes an activation of the adaptive immune response to produce cytotoxic T cells and neutralizing antibodies. We propose that SARS-CoV-2 activates the innate immune system through the renin-angiotensin and kallikrein-bradykinin pathways, blocks interferon production and reduces an effective adaptive immune response. This model has therapeutic implications.

Reproducible Metabolic Topographies Associated With Multiple System Atrophy: Network And Regional Analyses In Chinese And American Patient Cohorts, B. Shen, S. Wei, J. Ge, S. Peng, F. Liu, L. Li, S. Guo, P. Wu, D. Eidelberg, Y. Ma, +2 Additional Authors

Journal Articles

© 2020 The Authors Purpose: Multiple system atrophy (MSA) is an atypical parkinsonian syndrome and often difficult to discriminate clinically from progressive supranuclear palsy (PSP) and Parkinson's disease (PD) in early stages. Although a characteristic metabolic brain network has been reported for MSA, it is unknown whether this network can provide a clinically useful biomarker in different centers. This study was aimed to identify and cross-validate MSA-related brain network and assess its ability for differential diagnosis and clinical correlations in Chinese and American patient cohorts. Methods: We included 18F-FDG PET scans retrospectively from 128 clinically diagnosed parkinsonian patients (34 MSA, …

Nono Is A Novel Co-Factor Of Prdm1 And Regulates Inflammatory Response In Monocyte Derived-Dendritic Cells, K. Lee, S. H. Jang, H. Tian, S. J. Kim

Journal Articles

© Copyright © 2020 Lee, Jang, Tian and Kim. Proper expression of the transcription factor, Positive regulatory domain 1 (PRDM1), is required for maintaining homeostasis of human monocyte derived-dendritic cells (MO-DCs). The molecular mechanisms and gene targets of PRDM1 in B and T lymphocytes have been identified. However, the function of PRDM1 in dendritic cells (DCs) remains unclear. We investigate co-regulators of PRDM1 in MO-DCs identified by mass spectrometry (MS) and co-immunoprecipitation (Co-IP). Notably, non-POU domain-containing octamer-binding protein (NonO) was found to be a PRDM1 binding protein in the nucleus of MO-DCs. NonO is recruited to the PRDM1 binding site …

Ultrasound Powered Piezoelectric Neurostimulation Devices: A Commentary., T. Sun, J. Wright, T. Datta-Chaudhuri

Journal Articles

Conventional neurostimulation systems for preclinical research can be bulky and invasive due to the need for batteries or wired interfaces. Emerging as a new neural interface technique, ultrasound-powered piezoelectric neural stimulators work by converting ultrasound energy to electrical charge for neural stimulation. In addition to the benefits of wireless powering and miniaturization leading to less traumatic surgery, piezoelectric neural stimulators can also exhibit prolonged operational lifetimes for a long-term stable neural interface, and show promise for clinical translation. As one of first steps to demonstrate the value of ultrasound-powered piezoelectric neural interface, Li et al. developed a piezoelectric stimulator to …

In Utero Exposure To Endogenous Maternal Polyclonal Anti-Caspr2 Antibody Leads To Behavioral Abnormalities Resembling Autism Spectrum Disorder In Male Mice, C. Bagnall-Moreau, P. T. Huerta, D. Comoletti, A. La-Bella, R. Berlin, C. Zhao, B. T. Volpe, B. Diamond, L. Brimberg

Journal Articles

© 2020, The Author(s). The concept that exposure in utero to maternal anti-brain antibodies contributes to the development of autism spectrum disorders (ASD) has been entertained for over a decade. We determined that antibodies targeting Caspr2 are present at high frequency in mothers with brain-reactive serology and a child with ASD, and further demonstrated that exposure in utero to a monoclonal anti-Caspr2 antibody, derived from a mother of an ASD child, led to an-ASD like phenotype in male offspring. Now we propose a new model to study the effects of in utero exposure to anti-Caspr2 antibody. Dams immunized with the …

Surgical Gps Proof Of Concept For Scoliosis Surgery, Austin Tapp, Michel Audette

Computational Modeling & Simulation Engineering Faculty Publications

Scoliotic deformities may be addressed with either anterior or posterior approaches for scoliosis correction procedures. While typically quite invasive, the impact of these operations may be reduced through the use of computer-assisted surgery. A combination of physician-designated anatomical landmarks and surgical ontologies allows for real-time intraoperative guidance during computer-assisted surgical interventions. Predetermined landmarks are labeled on an identical patient model, which seeks to encompass vertebrae, intervertebral disks, ligaments, and other soft tissues. The inclusion of this anatomy permits the consideration of hypothetical forces that are previously not well characterized in a patient-specific manner. Updated ontologies then suggest procedural directions throughout …
