Homogeneous And Functional Group Tolerant Ring-Closing Metathesis For Dna-Encoded Chemical Libraries, Olivier B C Monty, Pranavanand Nyshadham, Kurt M Bohren, Murugesan Palaniappan, Martin M Matzuk, Damian W Young, Nicholas Simmons

Faculty, Staff and Students Publications

Reaction heterogeneity, poor pH control, and catalyst decomposition in the ring-closing metathesis (RCM) of DNA–chemical conjugates lead to poor yields of the cyclized products. Herein we address these issues with a RCM reaction system that includes a novel aqueous solvent combination to enable reaction homogeneity, an acidic buffer system which masks traditionally problematic functional groups, and a decomposition-resistant catalyst which maximizes conversion to the cyclized product. Additionally, we provide a systematic study of the substrate scope of the on-DNA RCM reaction, a demonstration of its applicability to a single-substrate DNA-encoded chemical library that includes sequencing analysis, and the first successful …

Characterization Of A Species E Adenovirus Vector As A Zika Virus Vaccine, Brianna L. Bullard, Brigette N. Corder, David N. Gordon, Theodore C. Pierson, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

The development of a safe and efficacious Zika virus (ZIKV) vaccine remains a global health priority. In our previous work, we developed an Adenovirus vectored ZIKV vaccine using a low-seroprevalent human Adenovirus type 4 (Ad4-prM-E) and compared it to an Ad5 vector (Ad5-prM-E). We found that vaccination with Ad4-prM-E leads to the development of a strong anti-ZIKV T-cell response without eliciting significant anti-ZIKV antibodies, while vaccination with Ad5-prM-E leads to the development of both anti-ZIKV antibody and T-cell responses in C57BL/6 mice. However, both vectors conferred protection against ZIKV infection in a lethal challenge model. Here we continued to characterize …

A Broad-Spectrum Antiviral Molecule, Ql47, Selectively Inhibits Eukaryotic Translation, Mélissanne De Wispelaere, Margot Carocci, Dominique J Burri, William J Neidermyer, Calla M Olson, Imme Roggenbach, Yanke Liang, Jinhua Wang, Sean P J Whelan, Nathanael S Gray, Priscilla L Yang

Faculty, Staff and Students Publications

Small-molecule inhibitors of translation are critical tools to study the molecular mechanisms of protein synthesis. In this study, we sought to characterize how QL47, a host-targeted, small-molecule antiviral agent, inhibits steady-state viral protein expression. We demonstrate that this small molecule broadly inhibits both viral and host protein synthesis and targets a translation step specific to eukaryotic cells. We show that QL47 inhibits protein neosynthesis initiated by both canonical cap-driven and noncanonical initiation strategies, most likely by targeting an early step in translation elongation. Our findings thus establish QL47 as a new small-molecule inhibitor that can be utilized to probe the …

Hierarchical Clustering Analyses Of Plasma Proteins In Subjects With Cardiovascular Risk Factors Identify Informative Subsets Based On Differential Levels Of Angiogenic And Inflammatory Biomarkers, Zachary Winder, Tiffany L. Sudduth, David W. Fardo, Qiang Cheng, Larry B. Goldstein, Peter T. Nelson, Frederick A. Schmitt, Gregory A. Jicha, Donna M. Wilcock

Sanders-Brown Center on Aging Faculty Publications

Agglomerative hierarchical clustering analysis (HCA) is a commonly used unsupervised machine learning approach for identifying informative natural clusters of observations. HCA is performed by calculating a pairwise dissimilarity matrix and then clustering similar observations until all observations are grouped within a cluster. Verifying the empirical clusters produced by HCA is complex and not well studied in biomedical applications. Here, we demonstrate the comparability of a novel HCA technique with one that was used in previous biomedical applications while applying both techniques to plasma angiogenic (FGF, FLT, PIGF, Tie-2, VEGF, VEGF-D) and inflammatory (MMP1, MMP3, MMP9, IL8, TNFα) protein data to …

The Role Of Noninvasive Tests For Differentiating Nash From Nafl And Diagnosing Advanced Fibrosis Among Patients With Nafld, Maya Balakrishnan, Rohit Loomba

Faculty, Staff and Students Publications

Assessing for the presence of non-alcoholic steatohepatitis (NASH) and the presence of advanced fibrosis is vital among patients with non-alcoholic fatty liver disease (NAFLD) as each is predictive of disease outcomes. A liver biopsy is the gold standard method for doing so but is impossible to perform among all patients with NAFLD. Reliable methods for noninvasively detecting for the presence of NASH and advanced fibrosis are thus a pressing need. The search for noninvasive tests has been more successful for advanced fibrosis than for NASH. Clinical prediction models and elastography have acceptable accuracy for ruling out advanced fibrosis; when used …

Rivastigmine Modifies The Α-Secretase Pathway And Potentially Early Alzheimer's Disease, Balmiki Ray, Bryan Maloney, Kumar Sambamurti, Hanuma K. Karnati, Peter T. Nelson, Nigel H. Greig, Debomoy K. Lahiri

Sanders-Brown Center on Aging Faculty Publications

Rivastigmine (or Exelon) is a cholinesterase inhibitor, currently used as a symptomatic treatment for mild-to-moderate Alzheimer’s disease (AD). Amyloid-β peptide (Aβ) generated from its precursor protein (APP) by β-secretase (or BACE1) and γ-secretase endoproteolysis. Alternative APP cleavage by α-secretase (a family of membrane-bound metalloproteases– Adamalysins) precludes the generation of toxic Aβ and yields a neuroprotective and neurotrophic secreted sAPPα fragment. Several signal transduction pathways, including protein kinase C and MAP kinase, stimulate α-secretase. We present data to suggest that rivastigmine, in addition to anticholinesterase activity, directs APP processing away from BACE1 and towards α-secretases. We treated rat neuronal PC12 cells …

Primum Non Nocere: Surgeons And The Politics Of Firearm Trauma, Kaushal Desai

Gibbon Surgical Review

The crisis of firearm violence in America continues to worsen and the call to action cannot be ignored. If we are to make a real impact, we must be just as skilled policy makers as proceduralists. We must wield the pen as well as we wield the scalpel. All the clinical knowledge and surgical skills in the world will make no difference if we do not reduce the number of firearm injuries. The skillset we need is policy analysis and lobbying, which can only be developed through political activism and engagement, not more practice questions and Online MedEd.

General Surgery 101: Nissen Fundoplication, Kelley Yuan, Tyler Bauer

Gibbon Surgical Review

The first time that medical students enter the OR can be a jarring experience. Successfully maintaining sterility is hard enough, but remembering relevant patient history, answering “pimp” questions, and performing basic suturing skills can make the third year medical student experience difficult. In this article we describe a common surgery performed by both general and thoracic surgeons with a specific focus on “medical student level” understanding. This piece is the product of a collaboration between an MS1 and MS4, both of whom are interested in a career in surgery. We hope you find it helpful!

Interview With Dr. Dawn Salvatore, Preeyal Patel

Gibbon Surgical Review

A medical student’s path to surgery is notoriously long and arduous. Traditionally, students who are interested in the field begin to prepare their qualifications from day one, especially given the competitive nature of acceptance into surgical programs. For students who develop an interest in surgery during their later years of medical school, it can be a daunting task to pursue a track in which they already feel behind. Often times, these students are discouraged from applying to surgical residencies, worrying that their non-traditional path may hinder their success. However, Dr. Dawn Salvatore can reassure students that a non-traditional path to …

The Utility Of Surgical Simulation In Student Education, Jared Raikin

Gibbon Surgical Review

The use of simulation in the field of surgery has become a heavily researched topic over the last few decades, but it is by no means a new concept. The first recorded use of surgical simulation dates back 2,500 years with evidence of nasal models for flap reconstruction made of leaf and clay.1 But simulation as we know it today did not take shape until the 1980s with the invention of the Comprehensive Anesthesia Simulation Environment (CASE) mannequins. The use of nonorganic simulation tools revolutionized the field and continues to play a large role in medical education. These modalities have …

Bedside To Bench: Basic Science Research During General Surgery Residency, Signe Caksa

Gibbon Surgical Review

Clinical, basic science, and quality improvement research is becoming increasingly integrated into general surgery residency programs, providing aspiring surgeons with an avenue to engage with academia and improve patient care early on in their careers. For example, as an essential part of their training, general surgery residents at Thomas Jefferson University Hospital (TJUH) complete one to two years of research, usually between their PGY3 and PGY4 years. The goal of this protected research time is for residents to gain hands-on surgical research skills and work on translational research projects that correlate with clinical cases, while also becoming more competitive for …

Longevity In Surgery: A Conversation With Two Temple Surgeons About How They Continually Find Joy In Their Careers, Kelsey Muir

Gibbon Surgical Review

Both Dr. Daly and Dr. Pontari describe the stress and pressure that comes with a long career in patient care, however intertwined with the stress is their overwhelming gratitude and joy for surgery. Maintaining that perspective for medicine and patient care has required two things: community and an outlet. Dr. Daly and Dr. Pontari expressed the need to be able to share their anxieties and struggles with someone to process the stress, the difficulties, and the demands of a surgical career.

Surgery Myths And Facts, Heli Patel

Gibbon Surgical Review

Throughout social media, television shows, movies, and “public perception”, surgical residents and attendings are often stereotyped into a personality that is most often incorrect. Unless you are a surgeon, it is often hard to understand what exactly the life entails. Add in some Hollywood drama and social media, and what you get is a wildly disproportionate picture of what surgeons’ personalities are like. As a medical student, it is often difficult to separate fact from fiction, so here are some of the most common myths debunked.

John H. Gibbon, Jr., Md

Gibbon Surgical Review

Dr. John Heysham Gibbon, Jr. graduated from Jefferson Medical College in 1927, and in a brief series of events, he was named Fellow at Massachusetts General Hospital. In 1930, he found himself assisting Dr. Edward Churchill in an emergency pulmonary embolectomy. At that time the procedure was one of desperation, as no patient in the U.S. had survived the removal of blood clots in open-heart surgery. As Dr. Gibbon recorded the patient’s waning vital signs prior to the procedure he thought, “If only we could remove the blood from her body by bypassing her lungs, and oxygenate it, then return …

Age Of Acquisition Impacts The Brain Differently Depending On Neuroanatomical Metric, Hannah Claussenius-Kalman, Kelly A Vaughn, Pilar Archila-Suerte, Arturo E Hernandez

Faculty, Staff and Student Publications

Although researchers generally agree that a certain set of brain areas underlie bilingual language processing, there is discrepancy regarding what effect timing of language acquisition has on these regions. We aimed to investigate the neuroanatomical correlates of age of acquisition (AoA), which has been examined previously, but with inconsistent results, likely influenced by methodological differences across studies. We analyzed gray matter density, volume, and thickness using whole-brain linear models in 334 bilinguals and monolinguals. Neuroanatomical correlates of AoA differed depending on gray matter metric. Relative to early bilinguals, late bilinguals had thicker cortex in language processing and cognitive control regions, …

For decades, physicians have administered corticosteroids in the perioperative period to infants undergoing heart surgery with cardiopulmonary bypass (CPB) to reduce the postoperative systemic inflammatory response to CPB. Some question this practice because steroid efficacy has not been conclusively demonstrated and because some studies indicate that steroids could have harmful effects. STRESS is a randomized, placebo-controlled, double-blind, multicenter trial designed to evaluate safety and efficacy of perioperative steroids in infants (age < 1 year) undergoing heart surgery with CPB. Participants (planned enrollment = 1,200) are randomized 1:1 to methylprednisolone (30 mg/kg) administered into the CPB pump prime versus placebo. The trial is nested within the existing infrastructure of the Society of Thoracic Surgeons Congenital Heart Surgery Database. The primary outcome is a global rank score of mortality, major morbidities, and hospital length of stay with components ranked commensurate with their clinical severity. Secondary outcomes include several measures of major postoperative morbidity, postoperative hospital length of stay, and steroid-related safety outcomes including prevalence of hyperglycemia and postoperative infectious complications. STRESS will be one of the largest trials ever conducted in children with heart disease and will answer a decades-old question related to safety and efficacy of perioperative steroids in infants undergoing heart surgery with CPB. The pragmatic "trial within a registry" design may provide a mechanism for conducting low-cost, high-efficiency trials in a heretofore-understudied patient population.

A Retrospective Matched-Cohort Study Of 3994 Lower Extremity Wounds Of Multiple Etiologies Across 644 Institutions Comparing A Bioactive Human Skin Allograft, Theraskin, Plus Standard Of Care, To Standard Of Care Alone, Geoff C Gurtner, Aimee D Garcia, Katie Bakewell, Jason B Alarcon

Faculty, Staff and Students Publications

Most chronic wounds are related to comorbidities, for which no clinical trials are performed. This retrospective propensity matched-cohort study examined data from 2 074 000 lower extremity wounds across 644 institutions to determine the effectiveness of TheraSkin plus standard of care (SOC; n = 1997) versus SOC alone (n = 1997). Multivariate modelling comparing outcomes such as healing rates, percent area reductions (PARs), amputations, recidivism, treatment completion, and medical transfers were evaluated. A higher proportion of wounds in the treatment group compared with the controls were more likely to close (68.3% versus 60.3%), particularly wounds with exposed structures (64% versus …

Risk Factors For Early Subsequent (Revision Or Contralateral) Acl Reconstruction: A Retrospective Database Study, Matthew C Gallo, Ioanna K Bolia, Omid Jalali, Santano Rosario, Alexis Rounds, Keemia Soraya Heidari, Nicholas A Trasolini, John P Prodromo, George Frederick Hatch, Alexander Evan Weber

Faculty, Staff and Students Publications

BACKGROUND: Many factors contribute to the risk for subsequent anterior cruciate ligament reconstruction (ACLR) within 2 years from the index procedure.

PURPOSE/HYPOTHESIS: The purpose of this study was 2-fold: (1) to evaluate the incidence of subsequent (revision or contralateral) ACLR at 2 years in a large cohort and (2) to explore the association between patient-specific factors and early subsequent ACLR risk by age group. We hypothesize that 2-year subsequent (revision or contralateral) ACLR rates will be low and that risk factors for subsequent (revision or contralateral) ACLR will vary depending on a patient's age group.

STUDY DESIGN: Case-control study; Level …

Losartan Rescues Inflammation-Related Mucociliary Dysfunction In Relevant Models Of Cystic Fibrosis, Michael D Kim, Nathalie Baumlin, Makoto Yoshida, Deepika Polineni, Sebastian F Salathe, Joseph K David, Charles A Peloquin, Adam Wanner, John S Dennis, Juliette Sailland, Philip Whitney, Frank T Horrigan, Juan R Sabater, William M Abraham, Matthias Salathe

Faculty, Staff and Students Publications

Rationale: Despite therapeutic progress in treating cystic fibrosis (CF) airway disease, airway inflammation with associated mucociliary dysfunction remains largely unaddressed. Inflammation reduces the activity of apically expressed large-conductance Ca²⁺-activated and voltage-dependent K⁺ (BK) channels, critical for mucociliary function in the absence of CFTR (CF transmembrane conductance regulator).

Objectives: To test losartan as an antiinflammatory therapy in CF using CF human bronchial epithelial cells and an ovine model of CF-like airway disease.

Methods: Losartan’s antiinflammatory effectiveness to rescue BK activity and thus mucociliary function was tested in vitro using primary, fully redifferentiated human airway epithelial cells homozygous for …

BACKGROUND: Lung cancer kills more people than any other cancer in the United States. In addition to environmental factors, lung cancer has genetic risk factors as well, though the genetic etiology is still not well understood. We have performed whole exome sequencing on 262 individuals from 28 extended families with a family history of lung cancer.

METHODS: Parametric genetic linkage analysis was performed on these samples using two distinct analyses-the lung cancer only (LCO) analysis, where only patients with lung cancer were coded as affected, and the all aggregated cancers (AAC) analysis, where other cancers seen in the pedigree were …

Faculty, Staff and Students Publications

BACKGROUND: Randomized clinical trials demonstrated the benefits of percutaneous coronary interventions (PCI) in diverse clinical settings. Patients with cancer were not routinely included in these studies.

METHODS/RESULTS: Literature search of PubMed, Cochrane, Medline, SCOPUS, EMBASE, and ClinicalTrials was conducted to identify studies that assessed one-year all-cause, cardiovascular and non-cardiovascular mortality in patients with historical or active cancer. Using the random effects model, we computed risk ratios (RRs) and standardized mean differences and their 95% confidence intervals for the dichotomous and continuous measures and outcomes, respectively. Of 171 articles evaluated in total, 5 eligible studies were included in this meta-analysis. In …

Aseptic Barriers Allow A Clean Contact For Contaminated Stethoscope Diaphragms, Rajiv Vasudevan, Ji H Shin, Jessica Chopyk, William F Peacock, Francesca J Torriani, Alan S Maisel, David T Pride

Faculty, Staff and Students Publications

OBJECTIVE: To determine whether a single-use stethoscope diaphragm barrier surface remains aseptic when placed on pathogen-contaminated stethoscopes.

METHODS: From May 31 to August 5, 2019, we tested 2 separate barriers using 3 different strains of 7 human pathogens, including extended-spectrum β-lactamase-producing

RESULTS: For all diaphragms with either of the 2 barriers tested, no growth was recorded for any of the pathogens. Stethoscopes with aseptic barriers remained sterile for up to 24 hours. These single-use barriers also provided aseptic surfaces when stethoscope diaphragms were inoculated with human specimens, including saliva, stool, urine, and sputum.

CONCLUSION: Disposable aseptic diaphragm barriers may provide …

Potential Use Of Biotherapeutic Bacteria To Target Colorectal Cancer-Associated Taxa, Gareth Lawrence, Maire Begley, Paul D. Cotter, Caitríona M. Guinane

Department of Biological Sciences Publications

The role of the gut microbiome in human health and disease is the focus of much attention. It has been widely agreed upon that our gut bacteria play a role in host immunity, nutrient absorption, digestion, metabolism, and other key drivers of health. Furthermore, certain microbial signatures and specific taxa have also been associated with the development of diseases, such as obesity; inflammatory bowel disease; and, indeed, colorectal cancer (CRC), which is the focus of this review. By extension, such taxa represent potential therapeutic targets. In particular, the emerging human pathogen Fusobacterium nucleatum represents an important agent in CRC development …

Metabolic Dysregulation In The Atp7b-/- Wilson's Disease Mouse Model, Clavia Ruth Wooton-Kee, Matthew Robertson, Ying Zhou, Bingning Dong, Zhen Sun, Kang Ho Kim, Hailan Liu, Yong Xu, Nagireddy Putluri, Pradip Saha, Cristian Coarfa, David D Moore, Alli M Nuotio-Antar

Inactivating mutations in the copper transporter Atp7b result in Wilson’s disease. The Atp7b−/− mouse develops hallmarks of Wilson’s disease. The activity of several nuclear receptors decreased in Atp7b−/− mice, and nuclear receptors are critical for maintaining metabolic homeostasis. Therefore, we anticipated that Atp7b−/− mice would exhibit altered progression of diet-induced obesity, fatty liver, and insulin resistance. Following 10 wk on a chow or Western-type diet (40% kcal fat), parameters of glucose and lipid homeostasis were measured. Hepatic metabolites were measured by liquid chromatography–mass spectrometry and correlated with transcriptomic data. Atp7b−/− mice fed a chow diet presented …

Proteome Alterations In Pancreatic Ductal Adenocarcinoma, Sheng Pan, Teresa A Brentnall, Ru Chen

Faculty, Staff and Students Publications

Proteins are the essential functional biomolecules profoundly implicated in all aspects of pancreatic tumorigenesis and its progression. While common genomic factors, such as KRAS, TP53, SMAD4, and CDKN2A have been well recognized in association of pancreatic ductal adenocarcinoma (PDAC), our understanding of functional changes at the proteome level merits further investigation. Malignance associated proteome alterations can be attributed to the convoluted outcomes from genetic, epigenetic and environmental factors in initiating and progressing PDAC, and may reflect on changes in protein expressional level, structure, localization, as well as post-translational modifications (PTMs) status. The study of localized or systemic proteome alterations in …

Trka Undergoes A Tetramer-To-Dimer Conversion To Open Trkh Which Enables Changes In Membrane Potential, Hanzhi Zhang, Yaping Pan, Liya Hu, M Ashley Hudson, Katrina S Hofstetter, Zhichun Xu, Mingqiang Rong, Zhao Wang, B V Venkataram Prasad, Steve W Lockless, Wah Chiu, Ming Zhou

Faculty, Staff and Students Publications

TrkH is a bacterial ion channel implicated in K+ uptake and pH regulation. TrkH assembles with its regulatory protein, TrkA, which closes the channel when bound to ADP and opens it when bound to ATP. However, it is unknown how nucleotides control the gating of TrkH through TrkA. Here we report the structures of the TrkH-TrkA complex in the presence of ADP or ATP. TrkA forms a tetrameric ring when bound to ADP and constrains TrkH to a closed conformation. The TrkA ring splits into two TrkA dimers in the presence of ATP and releases the constraints on TrkH, resulting …
