Department of Medicine Faculty Papers

Xiaoqinglong granules (XQLG) has been shown to be an effective therapy in asthma animal models. We reviewed the literature and conducted this study to assess the impact of XQLG as an add-on therapy to treatment with fluticasone/salmeterol (seretide) in adult patients with mild-to-moderate, persistent asthma. A total of 178 patients were randomly assigned to receive XQLG and seretide or seretide plus placebo for 90 days. Asthma control was assessed by asthma control test (ACT), symptoms scores, FEV(1), and PEF. Baseline patient-reported Chinese medicine (CM)-specific symptoms were analyzed to determine whether the symptoms may be possible indicators of treatment response by …

Vascular Endothelial Growth Factor (Vegf) Expression In Locally Advanced Prostate Cancer: Secondary Analysis Of Radiation Therapy Oncology Group (Rtog) 8610., Larry Pan, Seunghee Baek, Pamela R Edmonds, Mack Roach, Harvey Wolkov, Satish Shah, Alan Pollack, M Elizabeth Hammond, Adam P Dicker

The aim of the present study is to explore the potential of VEGF (also known as VEGF-A) as a prognostic and predictive biomarker among men with locally advanced prostate cancer.

METHODS: The analysis was performed using patients enrolled on RTOG 8610, a phase III randomized control trial of radiation therapy alone (Arm 1) versus short-term neoadjuvant and concurrent androgen deprivation and radiation therapy (Arm 2) in men with locally advanced prostate carcinoma. Tissue samples were obtained from …

Impairments In Neurogenesis Are Not Tightly Linked To Depressive Behavior In A Transgenic Mouse Model Of Alzheimer's Disease., Daniel M Iascone, Sneha Padidam, Mark S Pyfer, Xiaohong Zhang, Lijuan Zhao, Jeannie Chin

Farber Institute for Neuroscience Faculty Papers

Alzheimer's disease (AD), the most common cause of dementia, is also associated with depression. Although the precise mechanisms that lead to depression in AD are unknown, the impairments in adult hippocampal neurogenesis observed in AD may play a role. Adult-born neurons play a critical role in regulating both cognition and mood, and reduced hippocampal neurogenesis is associated with depression in other neurological disorders. To assess the relationship between Alzheimer's disease, neurogenesis, and depression, we studied human amyloid precursor protein (hAPP) transgenic mice, a well-characterized model of AD. We report that reductions in hippocampal neurogenesis are evident early in disease progression …

Behavioral And Transcriptome Alterations In Male And Female Mice With Postnatal Deletion Of Trkb In Dorsal Striatal Medium Spiny Neurons., Ellen M Unterwald, Michelle E. Page, Timothy B Brown, Jonathan S Miller, Marta Ruiz, Karen A Pescatore, Baoji Xu, Louis French Reichardt, Joel Beverley, Bin Tang, Heinz Steiner, Elizabeth A Thomas, Michelle E Ehrlich

Farber Institute for Neuroscience Faculty Papers

BACKGROUND: The high affinity tyrosine kinase receptor, TrkB, is the primary receptor for brain derived neurotrophic factor (BDNF) and plays an important role in development, maintenance and plasticity of the striatal output medium size spiny neuron. The striatal BDNF/TrkB system is thereby implicated in many physiologic and pathophysiologic processes, the latter including mood disorders, addiction, and Huntington's disease. We crossed a mouse harboring a transgene directing cre-recombinase expression primarily to postnatal, dorsal striatal medium spiny neurons, to a mouse containing a floxed TrkB allele (fB) mouse designed for deletion of TrkB to determine its role in the adult striatum.

RESULTS: …

Extracorporeal Membranous Oxygenation Mimics Aortic Dissection On Cat Scan., Philip Batista, Nicholas C. Cavarocchi, Hitoshi Hirose

Department of Surgery Faculty Papers

A 66 year-old female presented with refractory acute congestive heart failure, cardiogenic shock, and ventricular tachyarrhythmia. Veno-arterial extracorporeal membrane oxygenation (ECMO) was placed via femoral cannulation for salvage and stabilized. CAT scan of the chest performed as a part of heart transplant work-up, demonstrated an unequal distribution of intravenous contrast in the aortic arch (Figure 1). Radiologist’s preliminary reading was of “aortic dissection” while in fact this is truly “normal ECMO flow”.

An Economic Model To Value Companion Diagnostics In Non-Small-Cell Lung Cancer, Robert D. Lieberthal, Kellie Dudash, Rita S. Axelrod, Neil I. Goldfarb

Materials & methods: A decision analysis model examined alternative patient management strategies for patients with advanced NSCLC who were not amenable to surgical treatment. A review of the literature provided the variables used to develop a timely base case and sensitivity analysis. A potential future scenario was also modeled. The model includes three options: conventional treatment (CT), new treatment (NT) and companion diagnostic (CD) strategy. Results: In the base case analysis based upon current data, …

What Are The Characteristics That Explain Hospital Quality? A Longitudinal Pridit Approach, Robert D. Lieberthal, Dominique M. Comer

College of Population Health Faculty Papers

Health outcomes vary substantially between high and low quality institutions, meaning the difference between life and death in some cases. Prior literature has identified a number of variables that can be used to determine hospital quality, but methodologies for combining variables into an overall measure of hospital quality are not well developed. This analysis builds on the prior investigation of hospital quality by evaluating a method originally developed for the detection of healthcare fraud, Pridit, in the context of determining hospital quality. We developed a theoretical model to justify the application of Pridit to the hospital quality setting and then …

Skeletal Cell Differentiation Is Enhanced By Atmospheric Dielectric Barrier Discharge Plasma Treatment., Marla J Steinbeck, Natalie Chernets, Jun Zhang, Deepa S Kurpad, Gregory Fridman, Alexander Fridman, Theresa A. Freeman

Department of Orthopaedic Surgery Faculty Papers

Enhancing chondrogenic and osteogenic differentiation is of paramount importance in providing effective regenerative therapies and improving the rate of fracture healing. This study investigated the potential of non-thermal atmospheric dielectric barrier discharge plasma (NT-plasma) to enhance chondrocyte and osteoblast proliferation and differentiation. Although the exact mechanism by which NT-plasma interacts with cells is undefined, it is known that during treatment the atmosphere is ionized generating extracellular reactive oxygen and nitrogen species (ROS and RNS) and an electric field. Appropriate NT-plasma conditions were determined using lactate-dehydrogenase release, flow cytometric live/dead assay, flow cytometric cell cycle analysis, and Western blots to evaluate …

Inhibitory Effect Of Il-17 On Neural Stem Cell Proliferation And Neural Cell Differentiation., Zichen Li, Ke Li, Lin Zhu, Quancheng Kan, Yaping Yan, Priyanka Kumar, Hui Xu, Abdolmohamad Rostami, Guang-Xian Zhang

Department of Neurology Faculty Papers

BACKGROUND: IL-17, a Th17 cell-derived proinflammatory molecule, has been found to play an important role in the pathogenesis of autoimmune diseases, including multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). While IL-17 receptor (IL-17R) is expressed in many immune-related cells, microglia, and astrocytes, it is not known whether IL-17 exerts a direct effect on neural stem cells (NSCs) and oligodendrocytes, thus inducing inflammatory demyelination in the central nervous system.

METHODS: We first detected IL-17 receptor expression in NSCs with immunostaining and real time PCR. We then cultured NSCs with IL-17 and determined NSC proliferation by neurosphere formation …

Inhibitory Effect Of Matrine On Blood-Brain Barrier Disruption For The Treatment Of Experimental Autoimmune Encephalomyelitis., Su Zhang, Quan-Cheng Kan, Yuming Xu, Guang-Xian Zhang, Lin Zhu

Department of Neurology Faculty Papers

Dysfunction of the blood-brain barrier (BBB) is a primary characteristic of experimental autoimmune encephalomyelitis (EAE), an experimental model of multiple sclerosis (MS). Matrine (MAT), a quinolizidine alkaloid derived from the herb Radix Sophorae Flave, has been recently found to suppress clinical EAE and CNS inflammation. However, whether this effect of MAT is through protecting the integrity and function of the BBB is not known. In the present study, we show that MAT treatment had a therapeutic effect comparable to dexamethasone (DEX) in EAE rats, with reduced Evans Blue extravasation, increased expression of collagen IV, the major component of the basement …

Should We Use Preoperative Epoetin-Α In The Mildly Anemic Patient Undergoing Simultaneous Total Knee Arthroplasty?, Lawrence A Delasotta, Fabio Orozco, S Mehdi Jafari, Jamie L Blair, Alvin Ong

Rothman Institute Papers

Simultaneous knee arthroplasty is associated with significant blood loss. To prevent transfusion, three preoperative doses of epoetin-α were offered to mildly anemic simultaneous knee arthroplasty patients. A retrospective review, using ICD-9 codes, identified twenty patients from 2007-2009. Epoetin-α increased hemoglobin levels preoperatively (12.6 to 13.9, p

Aortic Dissection Presenting As Gait Disturbance: A Case Report., Michael Estreicher, Joseph Portale, Bernard Lopez

Department of Emergency Medicine Faculty Papers

Emergency medicine dogma traditionally teaches that aortic dissection presents as tearing chest pain, radiating to the back. This case report describes a 55 year old woman presenting with a left homonymous hemianopsia and resultant gait disturbance. Initial head CT demonstrated a right parietal infarct, and chest radiograph demonstrated a markedly widened mediastinum. Acute Stanford Type A aortic dissection was subsequently confirmed. This report provides further evidence for atypical, painless presentations of aortic dissection. Given recent literature on the increasing prevalence of painless dissection, the disease entity should be included in the differential diagnosis for stroke, and a simple portable chest …

Tumor Necrosis Factor-Α And Lymphotoxin-Α Mediate Myocardial Ischemic Injury Via Tnf Receptor 1, But Are Cardioprotective When Activating Tnf Receptor 2., Yanqing Zhang, Jianli Zhao, Wayne Bond Lau, Li-Yuan Jiao, Baojiang Liu, Yuexing Yuan, Xiaoliang Wang, Erhe Gao, Walter J Koch, Xin-Liang Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

OBJECTIVE: This study determines the roles of tumor necrosis factor-α (TNFα) and lymphotoxin-α (LTα) in post-myocardial infarction (post-MI) cardiac injury, and identifies the TNF receptor type responsible for TNFα- and LTα-mediated cardiac injury.

METHODS AND RESULTS: Adult male wild type (WT), TNFα(-/-), LTα(-/-), TNFR1(-/-), and TNFR2(-/-) mice were subjected to MI via coronary artery occlusion. Functional, histological, and biochemical analyses were performed 1 to 7 days post-MI. In WT mice, MI significantly increased both TNFα and LTα levels in plasma, but in distinct temporal manner. Plasma TNFα peaked 1 day after MI, and decreased toward baseline 3 days after MI. …

Ginsenoside Rd Attenuates Myocardial Ischemia/Reperfusion Injury Via Akt/Gsk-3Β Signaling And Inhibition Of The Mitochondria-Dependent Apoptotic Pathway., Yang Wang, Xu Li, Xiaoliang Wang, Wayne Bond Lau, Yajing Wang, Yuan Xing, Xing Zhang, Xinliang Ma, Feng Gao

Department of Emergency Medicine Faculty Papers

Evidence suggests Ginsenoside Rd (GSRd), a biologically active extract from the medical plant Panax Ginseng, exerts antioxidant effect, decreasing reactive oxygen species (ROS) formation. Current study determined the effect of GSRd on myocardial ischemia/reperfusion (MI/R) injury (a pathological condition where ROS production is significantly increased) and investigated the underlying mechanisms. The current study utilized an in vivo rat model of MI/R injury and an in vitro neonatal rat cardiomyocyte (NRC) model of simulated ischemia/reperfusion (SI/R) injury. Infarct size was measured by Evans blue/TTC double staining. NRC injury was determined by MTT and lactate dehydrogenase (LDH) leakage assay. ROS accumulation and …

Different Mechanisms Of Inflammation Induced In Virus And Autoimmune-Mediated Models Of Multiple Sclerosis In C57bl6 Mice., Abhinoy Kishore, Anurag Kanaujia, Soma Nag, A M Rostami, Lawrence C. Kenyon, Kenneth S Shindler, Jayasri Das Sarma

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the human central nervous system (CNS). Neurotropic demyelinating strain of MHV (MHV-A59 or its isogenic recombinant strain RSA59) induces MS-like disease in mice mediated by microglia, along with a small population of T cells. The mechanism of demyelination is at least in part due to microglia-mediated myelin stripping, with some direct axonal injury. Immunization with myelin oligodendrocyte glycoprotein (MOG) induces experimental autoimmune encephalomyelitis (EAE), a mainly CD4(+) T-cell-mediated disease, although CD8(+) T cells may play a significant role in demyelination. It is possible that both autoimmune and nonimmune mechanisms such as …

Microrna-138 Regulates Hypoxia-Induced Endothelial Cell Dysfunction By Targeting S100a1., Anagha Sen, Shumei Ren, Carolin Lerchenmüller, Jianxin Sun, Norbert Weiss, Patrick Most, Karsten Peppel

Center for Translational Medicine Faculty Papers

The Ca(2+) sensor S100A1 is essential for proper endothelial cell (EC) nitric oxide (NO) synthase (eNOS) activation. S100A1 levels are greatly reduced in primary human microvascular ECs subjected to hypoxia, rendering them dysfunctional. However mechanisms that regulate S100A1 levels in ECs are unknown. Here we show that ECs transfected with a S100A1-3' untranslated region (UTR) luciferase reporter construct display significantly reduced gene expression when subjected to low oxygen levels or chemical hypoxia. Bioinformatic analysis suggested that microRNA -138 (MiR-138) could target the 3'UTR of S100A1. Patients with critical limb ischemia (CLI) or mice subjected to femoral artery resection (FAR) displayed …

Adp Protects Cardiac Mitochondria Under Severe Oxidative Stress., Niina Sokolova, Shi Pan, Sarah Provazza, Gisela Beutner, Marko Vendelin, Rikke Birkedal, Shey-Shing Sheu

Center for Translational Medicine Faculty Papers

ADP is not only a key substrate for ATP generation, but also a potent inhibitor of mitochondrial permeability transition pore (mPTP). In this study, we assessed how oxidative stress affects the potency of ADP as an mPTP inhibitor and whether its reduction of reactive oxygen species (ROS) production might be involved. We determined quantitatively the effects of ADP on mitochondrial Ca(2+) retention capacity (CRC) until the induction of mPTP in normal and stressed isolated cardiac mitochondria. We used two models of chronic oxidative stress (old and diabetic mice) and two models of acute oxidative stress (ischemia reperfusion (IR) and tert-butyl …

Investigating The Role For Il-21 In Rabies Virus Vaccine-Induced Immunity., Corin L Dorfmeier, Evgeni P Tzvetkov, Anthony Gatt, James P Mcgettigan

Department of Microbiology and Immunology Faculty Papers

Over two-thirds of the world's population lives in regions where rabies is endemic, resulting in over 15 million people receiving multi-dose post-exposure prophylaxis (PEP) and over 55,000 deaths per year globally. A major goal in rabies virus (RABV) research is to develop a single-dose PEP that would simplify vaccination protocols, reduce costs associated with RABV prevention, and save lives. Protection against RABV infections requires virus neutralizing antibodies; however, factors influencing the development of protective RABV-specific B cell responses remain to be elucidated. Here we used a mouse model of IL-21 receptor-deficiency (IL-21R-/-) to characterize the role for IL-21 in RABV …

Comparison Of Heterologous Prime-Boost Strategies Against Human Immunodeficiency Virus Type 1 Gag Using Negative Stranded Rna Viruses., Tessa M Lawrence, Celestine N Wanjalla, Emily A Gomme, Christoph Wirblich, Anthony Gatt, Elena Carnero, Adolfo García-Sastre, Douglas S Lyles, James P Mcgettigan, Matthias J Schnell

Department of Microbiology and Immunology Faculty Papers

This study analyzed a heterologous prime-boost vaccine approach against HIV-1 using three different antigenically unrelated negative-stranded viruses (NSV) expressing HIV-1 Gag as vaccine vectors: rabies virus (RABV), vesicular stomatitis virus (VSV) and Newcastle disease virus (NDV). We hypothesized that this approach would result in more robust cellular immune responses than those achieved with the use of any of the vaccines alone in a homologous prime-boost regimen. To this end, we primed BALB/c mice with each of the NSV-based vectors. Primed mice were rested for thirty-five days after which we administered a second immunization with the same or heterologous NSV-Gag viruses. …

Isolated Laryngeal Leishmaniasis In Immunocompetent Patients: An Underdiagnosed Disease., Salvatore Cocuzza, Alessio Strazzulla, Marilia Rita Pinzone, Stefano Cosentino, Agostino Serra, Rosario Caltabiano, Salvatore Lanzafame, Bruno Cacopardo, Giuseppe Nunnari

Department of Microbiology and Immunology Faculty Papers

We describe a case of isolated primary laryngeal leishmaniasis in an immunocompetent Italian patient with a previous medical history negative for visceral or cutaneous leishmaniasis, presenting with hoarseness. We also summarize the epidemiological, clinical, and diagnostic features and the therapeutic management of other cases of laryngeal leishmaniasis in immunocompetent subjects, described in the literature. Considering the insidious and nonspecific clinical presentation, the increasing number of different forms of mild or underestimated immunosuppressive conditions, and the number of people travelling in endemic zones, along with the ability of Leishmania amastigotes to survive for a long period in the body, we believe …

Glutamine Supplementation Alleviates Vasculopathy And Corrects Metabolic Profile In An In Vivo Model Of Endothelial Cell Dysfunction., Francesco Addabbo, Qiuying Chen, Dhara P Patel, May Rabadi, Brian Ratliff, Frank Zhang, Jean-Francois Jasmin, Michael Wolin, Michael Lisanti, Steven S Gross, Michael S Goligorsky

Kimmel Cancer Center Faculty Papers

Endothelial Cell Dysfunction (ECD) is a recognized harbinger of a host of chronic cardiovascular diseases. Using a mouse model of ECD triggered by treatment with L-Nω-methylarginine (L-NMMA), we previously demonstrated that renal microvasculature displays a perturbed protein profile, including diminished expression of two key enzymes of the Krebs cycle associated with a Warburg-type suppression of mitochondrial metabolism. We hypothesized that supplementation with L-glutamine (GLN), that can enter the Krebs cycle downstream this enzymatic bottleneck, would normalize vascular function and alleviate mitochondrial dysfunction. To test this hypothesis, mice with chronic L-NMMA-induced ECD were co-treated with GLN at different concentrations for 2 …

BACKGROUND: Humanized KS-interleukin-2 (huKS-IL2), an immunocytokine with specificity for epithelial cell adhesion molecule (EpCAM), has demonstrated favorable tolerability and immunologic activity as a single agent.

METHODS: Phase 1b study in patients with EpCAM-positive advanced solid tumors to determine the maximum tolerated dose (MTD) and safety profile of huKS-IL2 in combination with low-dose cyclophosphamide. Treatment consisted of cyclophosphamide (300 mg/m2 on day 1), and escalating doses of huKS-IL2 (0.5-4.0 mg/m2 IV continuous infusion over 4 hours) on days 2, 3, and 4 of each 21-day cycle. Safety, pharmacokinetic profile, immunogenicity, anti-tumor and biologic activity were evaluated.

RESULTS: Twenty-seven patients were treated …

Development Of Frataxin Gene Expression Measures For The Evaluation Of Experimental Treatments In Friedreich's Ataxia., Heather L Plasterer, Eric C Deutsch, Matthew Belmonte, Elizabeth Egan, David R Lynch, James R Rusche

Department of Pediatrics Faculty Papers

BACKGROUND: Friedreich ataxia is a progressive neurodegenerative disorder caused by GAA triplet repeat expansions or point mutations in the FXN gene and, ultimately, a deficiency in the levels of functional frataxin protein. Heterozygous carriers of the expansion express approximately 50% of normal frataxin levels yet manifest no clinical symptoms, suggesting that therapeutic approaches that increase frataxin may be effective even if frataxin is raised only to carrier levels. Small molecule HDAC inhibitor compounds increase frataxin mRNA and protein levels, and have beneficial effects in animal models of FRDA.

METHODOLOGY/PRINCIPAL FINDINGS: To gather data supporting the use of frataxin as a …

Rewarming For Accidental Hypothermia In An Urban Medical Center Using Extracorporeal Membrane Oxygenation., David Morley, Kentaro Yamane, Rika O'Malley, Nicholas Cavarocchi, Hitoshi Hirose

Department of Emergency Medicine Faculty Papers

BACKGROUND: Accidental hypothermia complicated by cardiac arrest carries a high mortality rate in urban areas. For moderate hypothermia cases conventional rewarming methods are usually adequate, however in severe cases extracorporeal membrane oxygenation (ECMO) is known to provide the most efficient rewarming with complete cardiopulmonary support. We report a case of severe hypothermia complicated by prolonged cardiac arrest successfully resuscitated using ECMO.

CASE REPORT: A 45 year old female was brought to our emergency department with a core body temperature

CONCLUSIONS: This case demonstrates the advantages of advanced internal rewarming techniques, such as ECMO, for quick and efficient rewarming of severely …

Identification Of Distant Drug Off-Targets By Direct Superposition Of Binding Pocket Surfaces., Marcel Schumann, Roger S Armen

College of Pharmacy Faculty Papers

Correctly predicting off-targets for a given molecular structure, which would have the ability to bind a large range of ligands, is both particularly difficult and important if they share no significant sequence or fold similarity with the respective molecular target ("distant off-targets"). A novel approach for identification of off-targets by direct superposition of protein binding pocket surfaces is presented and applied to a set of well-studied and highly relevant drug targets, including representative kinases and nuclear hormone receptors. The entire Protein Data Bank is searched for similar binding pockets and convincing distant off-target candidates were identified that share no significant …

Fibroblast Growth Factor-2 (Fgf2) And Syndecan-1 (Sdc1) Are Potential Biomarkers For Putative Circulating Cd15+/Cd30+ Cells In Poor Outcome Hodgkin Lymphoma Patients., Rajendra Gharbaran, Andre Goy, Takemi Tanaka, Jongwhan Park, Chris Kim, Nafis Hasan, Swathi Vemulapalli, Sreeja Sarojini, Madalina Tuluc, Kip Nalley, Pritish Bhattacharyya, Andrew Pecora, K Stephen Suh

College of Pharmacy Faculty Papers

BACKGROUND: High risk, unfavorable classical Hodgkin lymphoma (cHL) includes those patients with primary refractory or early relapse, and progressive disease. To improve the availability of biomarkers for this group of patients, we investigated both tumor biopsies and peripheral blood leukocytes (PBL) of untreated (chemo-naïve, CN) Nodular Sclerosis Classic Hodgkin Lymphoma (NS-cHL) patients for consistent biomarkers that can predict the outcome prior to frontline treatment.

METHODS AND MATERIALS: Bioinformatics data mining was used to generate 151 candidate biomarkers, which were screened against a library of 10 HL cell lines. Expression of FGF2 and SDC1 by CD30+ cells from HL patient samples …

Dynein And Dynactin Leverage Their Bivalent Character To Form A High-Affinity Interaction., Amanda E Siglin, Shangjin Sun, Jeffrey K Moore, Sarah Tan, Martin Poenie, James D Lear, Tatyana Polenova, John A Cooper, John C Williams

Department of Biochemistry and Molecular Biology Faculty Papers

Cytoplasmic dynein and dynactin participate in retrograde transport of organelles, checkpoint signaling and cell division. The principal subunits that mediate this interaction are the dynein intermediate chain (IC) and the dynactin p150(Glued); however, the interface and mechanism that regulates this interaction remains poorly defined. Herein, we use multiple methods to show the N-terminus of mammalian dynein IC, residues 10-44, is sufficient for binding p150(Glued). Consistent with this mapping, monoclonal antibodies that antagonize the dynein-dynactin interaction also bind to this region of the IC. Furthermore, double and triple alanine point mutations spanning residues 6 to 19 in the yeast IC homolog, …

Developing Ambulatory Care Registered Nurse Competencies For Care Coordination And Transition Management, Sheila Haas, Beth Ann Swan, Traci Haynes

College of Nursing Faculty Papers & Presentations

The need for care coordination and management of transitions between Patient-Centered Medical Home providers, outpatient and community settings, including the Accountable Care Organization is often overlooked, episodic, and accountability for coordinating care and managing transitions between providers and services is lacking.
