Emerging Cellular And Molecular Strategies For Enhancing Central Nervous System (Cns) Remyelination., Mohammad Abu-Rub, Robert H Miller

Anatomy and Regenerative Biology Faculty Publications

Myelination is critical for the normal functioning of the central nervous system (CNS) in vertebrates. Conditions in which the development of myelin is perturbed result in severely compromised individuals often with shorter lifespans, while loss of myelin in the adult results in a variety of functional deficits. Although some form of spontaneous remyelination often takes place, the repair process as a whole often fails. Several lines of evidence suggest it is feasible to develop strategies that enhance the capacity of the CNS to undergo remyelination and potentially reverse functional deficits. Such strategies include cellular therapies using either neural or mesenchymal …

Tgf-Β Sustains Tumor Progression Through Biochemical And Mechanical Signal Transduction., Robert L Furler, Douglas F Nixon, Christine A Brantner, Anastas Popratiloff, Christel H Uittenbogaart

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Transforming growth factor β (TGF-β) signaling transduces immunosuppressive biochemical and mechanical signals in the tumor microenvironment. In addition to canonical SMAD transcription factor signaling, TGF-β can promote tumor growth and survival by inhibiting proinflammatory signaling and extracellular matrix (ECM) remodeling. In this article, we review how TGF-β activated kinase 1 (TAK1) activation lies at the intersection of proinflammatory signaling by immune receptors and anti-inflammatory signaling by TGF-β receptors. Additionally, we discuss the role of TGF-β in the mechanobiology of cancer. Understanding how TGF-β dampens proinflammatory responses and induces pro-survival mechanical signals throughout cancer development is critical for designing therapeutics that …

Surgery Faculty Publications

AIMS: Type 2 diabetes is associated with endothelial dysfunction leading to cardiovascular disease. CD34+ endothelial Progenitor Cells (EPCs) are responsible for endothelial repair and neo-angiogenesis and can be used as a cardiovascular disease risk biomarker. This study investigated whether the addition of saxagliptin, a DPP-IV inhibitor, to metformin, may reduce cardiovascular disease risk in addition to improving glycemic control in Type 2 diabetes patients.

METHODS: In 12 week, double-blind, randomized placebo-controlled trial, 42 subjects already taking metformin 1-2 grams/day were randomized to placebo or saxagliptin 5 mg. Subjects aged 40-70 years with diabetes for < 10 years, with no known cardiovascular disease, BMI 25-39.9, HbA1C 6-9% were included. We evaluated EPCs number, function, surface markers and gene expression, in addition to arterial stiffness, blood biochemistries, resting energy expenditure, and body composition parameters. A mixed model regression to examine saxagliptin vs placebo, accounting for within-subject autocorrelation, was done with SAS (p < 0.05).

RESULTS: Although there was no significant …

The Small Rna Complement Of Adult Schistosoma Haematobium., Andreas J Stroehlein, Neil D Young, Pasi K Korhonen, Ross S Hall, Aaron R Jex, Bonnie L Webster, David Rollinson, Paul J Brindley, Robin B Gasser

Microbiology, Immunology, and Tropical Medicine Faculty Publications

BACKGROUND: Blood flukes of the genus Schistosoma cause schistosomiasis-a neglected tropical disease (NTD) that affects more than 200 million people worldwide. Studies of schistosome genomes have improved our understanding of the molecular biology of flatworms, but most of them have focused largely on protein-coding genes. Small non-coding RNAs (sncRNAs) have been explored in selected schistosome species and are suggested to play essential roles in the post-transcriptional regulation of genes, and in modulating flatworm-host interactions. However, genome-wide small RNA data are currently lacking for key schistosomes including Schistosoma haematobium-the causative agent of urogenital schistosomiasis of humans.

METHODOLOGY: MicroRNAs (miRNAs) and other …

Amygdala Corticofugal Input Shapes Mitral Cell Responses In The Accessory Olfactory Bulb, Livio Oboti, Eleonora Russo, Tuyen Tran, Daniel Durstewitz, Joshua G. Corbin

Pediatrics Faculty Publications

Interconnections between the olfactory bulb and the amygdala are a major pathway for triggering strong behavioral responses to a variety of odorants. However, while this broad mapping has been established, the patterns of amygdala feedback connectivity and the influence on olfactory circuitry remain unknown. Here, using a combination of neuronal tracing approaches, we dissect the connectivity of a cortical amygdala [posteromedial cortical nucleus (PmCo)] feedback circuit innervating the mouse accessory olfactory bulb. Optogenetic activation of PmCo feedback mainly results in feedforward mitral cell (MC) inhibition through direct excitation of GABAergic granule cells. In addition, LED-driven activity of corticofugal afferents increases …

An Assessment Of Cultural Perceptions And Recognition Of Ebola Virus Disease, And Its Correlation With Traditional Burial Practice In Rural Guinea, Chulwoo Park, Amira Roess, Sally Lahm, Mamadou Kally Bah, Mohamed Campel Camara, John Sandberg

GW Research Days 2016 - 2020

Background:

In the midst of the unprecedented Ebola outbreak in West Africa during 2014-2016, the humanitarian response to control the disease was hampered in part because there was a limited understanding of local traditional rituals or indigenous medicine (ethnomedicine) on the part of the responders. The Ebola outbreak claimed 11,310 lives, more than all other outbreaks combined. West African burial funeral ceremonies and surrounding rituals may have hindered interventions that included the forceful removal of the sick or dead from the community.

Objective:

Our objective was to understand transmission associated with traditional burial practices in rural Guinea. Through the lens …

Tumor Surveillance Using Liquid Biome In Pediatric High Grade Gliomas, Erin Bonner, Eshini Panditharatna, Madhuri Kambhampati, Stefaan Van Gool, Wilfried Stuecker, Roger J. Packer, Javad Nazarian

GW Research Days 2016 - 2020

Immunotherapy is currently being used to treat pediatric brain cancer, though its efficacy in treating patients with diffuse intrinsic pontine glioma (DIPG), the deadliest pediatric brain tumor, has not been evaluated. MRI is the gold standard for monitoring tumor response to therapy, but is limited by pseudoresponse and psuedoprogression: post-treatment, immune cells infiltrate the primary tumor causing transient tumor enlargement, which falsely resembles tumor progression on MRI. Thus, it is critical to develop more accurate approaches to monitor tumor response to immunotherapy. Here, we use a liquid biopsy platform we have already established to monitor tumor response to therapy, to …

Evaluation Of Group Movement Programs (Plié And Paired Plié) For People With Memory Loss, Alzheimer’S Disease Or Dementia, Martin Blanco, Deborah Barnes

GW Research Days 2016 - 2020

Background: Dementia ascertainment is difficult and costly, hindering the use of large, representative studies such as the Health and Retirement Study (HRS) to monitor trends or disparities in dementia. To address this issue, multiple groups of researchers have developed algorithms to classify dementia status in HRS participants using data from HRS and the Aging, Demographics, and Memory Study (ADAMS), an HRS sub-study that systematically ascertained dementia status. However, the relative performance of each algorithm has not been systematically evaluated.

Objective: To compare the performance of five existing algorithms, overall and by sociodemographic subgroups.

Methods: We created two standardized datasets: (a) …

Disparities In Diabetes Rates And Quality Of Care Within Immigrants In The Usa, Anyun Chatterjee, Martin Blanco, George Gray

GW Research Days 2016 - 2020

Immigrants to the USA present an interesting opportunity to test the classical public health question of the impact of place on a health outcome. Diabetes is a prevalent disease in the USA which is slated to rise in rate in the future. Currently, 9.4% of the country is diabetic, and another 28% of the country is prediabetic. We posed the question - is this impact felt disproportionately by immigrants as they live in the US for a decade or more? Our preliminary literature search indicated that this has not been studied extensively, although the impact of American fast food on …

Legionnaire's Disease Presenting With Severe Rhabdomyolysis And Acute Renal Failure: A Case Report, Benjamin Plotz, Victoria K. Shanmugam

GW Research Days 2016 - 2020

Legionnaire's disease is caused by Legionella species, and is a recognized but rare cause of rhabdomyolysis. Legionella species live in water, and exposure to inoculated water systems leads to transmission of the disease, and commonly causes pneumonia in infected individuals. While the mechanism of muscle destruction legionella infection causes is not fully understood, the prevailing theory is that rhabdomyolysis is linked to an endotoxin released by the bacteria into the blood stream. Massive muscle necrosis manifests as limb weakness, muscle pain, swelling, and gross pigmenturia due to the release of electrolytes, myoglobin, and other sarcoplasmic proteins into the bloodstream. A …

Urinary Tract Infection In Children With Spina Bifida And Spinal Cord Injury., Obumneke Amadi, Harolyn Belcher

GW Research Days 2016 - 2020

Introduction: Urinary tract infections (UTI) are one of the most common bacterial infections (Schappert & Rechtsteiner, 2008; Litwin et al., 2005). Data from the National Ambulatory Medical Care Survey estimated that UTI caused 8.1 million physicians visits (Schappert & Rechtsteiner, 2008). Children with spina bifida (SB) and spinal cord injury (SCI) are at high risk for UTI (Ouyang et al., 2010; Nair et al., 2005). The purpose of this study was to examine the organisms associated with UTI in the population of children with SB and SCI who were treated in out-patient and in-patient settings at the Kennedy Krieger …

Cost-Effectiveness Of Alternative Anticoagulation Strategies For Postoperative Management Of Total Knee Arthroplasty Patients, Savannah R. Smith, Jeffrey Katz, Elena Losina

GW Research Days 2016 - 2020

Background: Anticoagulation is essential for deep vein thrombosis (DVT) and pulmonary embolism (PE) prevention following total knee arthroplasty (TKA). Some research has suggested that longer duration anticoagulation can substantially reduce the risks of DVT and PE; however, in the absence of definitive recommendations, physicians are left weighing the risks of DVT and PE against those of anticoagulation, including gastrointestinal (GI) and central nervous system (CNS) hemorrhage and increased likelihood of prosthetic joint infection (PJI). We conducted a cost-effectiveness analysis to evaluate the benefits and risks of 14- and 35-day therapy with the most commonly prescribed anticoagulants post-TKA.

Background: Anticoagulation is …

Effects Of An Online Diabetes Self-Management Educational Class On Perceived Self-Efficacy In Patients With Type 2 Diabetes Mellitus, Samantha L. Sugarman, Dnp, Ba, Bsn, Msn, Fnp-C

Doctor of Nursing Practice Projects

Background: Diabetes is a complex, chronic disease that, without adequate glycemic control, may result in avoidable complications. Without proper diabetes self-management education, achieving good glycemic control is difficult. Furthermore, lacking self-efficacy to perform such tasks may prevent even the most educated patients from achieving good glycemic control. Studies have shown that live diabetes education has improved self-efficacy in patients with diabetes, but few look at the effects of a lecture-style educational format in an online approach.

Objectives: The purpose of this study is to determine if an online, lecture-style diabetes self-management educational class will improve self-efficacy among patients with type …

Tumorigenic Proteins Upregulated In The Mycn-Amplified Imr-32 Human Neuroblastoma Cells Promote Proliferation And Migration., Hayat Zaatiti, Jad Abdallah, Zeina Nasr, George Khazen, Anthony Sandler, Tamara J Abou-Antoun

Surgery Faculty Publications

Childhood neuroblastoma is one of the most common types of extra-cranial cancer affecting children with a clinical spectrum ranging from spontaneous regression to malignant and fatal progression. In order to improve the clinical outcomes of children with high-risk neuroblastoma, it is crucial to understand the tumorigenic mechanisms that govern its malignant behaviors. MYCN proto-oncogene, bHLH transcription factor (MYCN) amplification has been implicated in the malignant, treatment-evasive nature of aggressive, high-risk neuroblastoma. In this study, we used a SILAC approach to compare the proteomic signatures of MYCN-amplified IMR-32 and non-MYCN-amplified SK-N-SH human neuroblastoma cells. Tumorigenic proteins, including fatty-acid binding protein 5 …

Impaired Type I Interferon Regulation In The Blood Transcriptome Of Recurrent Asthma Exacerbations., Jose L Gomez, Maria P Diaz, Gustavo Nino, Clemente J Britto

Pediatrics Faculty Publications

BACKGROUND: Asthma exacerbations are an important cause of morbidity in asthma. Respiratory infections are often involved in asthma exacerbations in both children and adults. Some individuals with asthma have increased susceptibility to viral infections and as a result increased rates of asthma exacerbations. We sought to identify a transcriptomic signature in the blood associated with asthma exacerbations triggered by respiratory infections (AETRI) and determine its association with increased risk for asthma exacerbations.

METHODS: We conducted a two-step study using publicly available, previously generated transcriptomic signatures in peripheral blood mononuclear cells (PBMCs) from asthmatics to identify novel markers of increased risk …

Drug Repurposing For Schistosomiasis: Combinations Of Drugs Or Biomolecules., Maria João Gouveia, Paul J Brindley, Fátima Gärtner, José M Correia Da Costa, Nuno Vale

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Schistosomiasis is a major neglected tropical disease. Control of schistosomiasis currently relies on a single drug, praziquantel, and despite its efficacy against the all schistosome species that parasitize humans, it displays some problematic drawbacks and alone is ineffective in counteracting adverse pathologies associated with infection. Moreover, due to the development of the potential emergence of PZQ-resistant strains, the search for additional or alternative antischistosomal drugs have become a public health priority. The current drug discovery for schistosomiasis has been slow and uninspiring. By contrast, repurposing of existing approved drugs may offer a safe, rapid and cost-effective alternative. Combined treatment with …

Sertraline, Paroxetine, And Chlorpromazine Are Rapidly Acting Anthelmintic Drugs Capable Of Clinical Repurposing., Janis C Weeks, William M Roberts, Caitlyn Leasure, Brian M Suzuki, Kristin J Robinson, John M Hawdon, +Several Additional Authors

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Parasitic helminths infect over 1 billion people worldwide, while current treatments rely on a limited arsenal of drugs. To expedite drug discovery, we screened a small-molecule library of compounds with histories of use in human clinical trials for anthelmintic activity against the soil nematode Caenorhabditis elegans. From this screen, we found that the neuromodulatory drugs sertraline, paroxetine, and chlorpromazine kill C. elegans at multiple life stages including embryos, developing larvae and gravid adults. These drugs act rapidly to inhibit C. elegans feeding within minutes of exposure. Sertraline, paroxetine, and chlorpromazine also decrease motility of adult Trichuris muris whipworms, prevent hatching …

Neural Correlates Of Taste Reactivity In Autism Spectrum Disorder., Jason A Avery, John E Ingeholm, Sophie Wohltjen, Meghan Collins, Cameron D Riddell, Stephen J Gotts, Lauren Kenworthy, Gregory L Wallace, W Kyle Simmons, Alex Martin

Psychiatry and Behavioral Sciences Faculty Publications

Selective or 'picky' eating habits are common among those with autism spectrum disorder (ASD). These behaviors are often related to aberrant sensory experience in individuals with ASD, including heightened reactivity to food taste and texture. However, very little is known about the neural mechanisms that underlie taste reactivity in ASD. In the present study, food-related neural responses were evaluated in 21 young adult and adolescent males diagnosed with ASD without intellectual disability, and 21 typically-developing (TD) controls. Taste reactivity was assessed using the Adolescent/Adult Sensory Profile, a clinical self-report measure. Functional magnetic resonance imaging was used to evaluate hemodynamic responses …
