Csf Inflammatory Markers Differ In Gram-Positive Versus Gram-Negative Shunt Infections., Gwenn L. Skar, David C. Synhorst, Matthew Beaver, Jessica N. Snowden

Manuscripts, Articles, Book Chapters and Other Papers

Background: Cerebrospinal fluid (CSF) shunt placement is frequently complicated by bacterial infection. Shunt infection diagnosis relies on bacterial culture of CSF which can often produce false-negative results. Negative cultures present a conundrum for physicians as they are left to rely on other CSF indices, which can be unremarkable. New methods are needed to swiftly and accurately diagnose shunt infections. CSF chemokines and cytokines may prove useful as diagnostic biomarkers. The objective of this study was to evaluate the potential of systemic and CSF biomarkers for identification of CSF shunt infection.

Methods: We conducted a retrospective chart review of children with …

Patient-derived tumor xenograft (PDX) mouse models are a versatile oncology research platform for studying tumor biology and for testing chemotherapeutic approaches tailored to genomic characteristics of individual patients' tumors. PDX models are generated and distributed by a diverse group of academic labs, multi-institution consortia and contract research organizations. The distributed nature of PDX repositories and the use of different metadata standards for describing model characteristics presents a significant challenge to identifying PDX models relevant to specific cancer research questions. The Jackson Laboratory and EMBL-EBI are addressing these challenges by co-developing PDX Finder, a comprehensive open global catalog of PDX models …

Faculty Research 2019

Thick-filament sarcomere mutations are a common cause of hypertrophic cardiomyopathy (HCM), a disorder of heart muscle thickening associated with sudden cardiac death and heart failure, with unclear mechanisms. We engineered four isogenic induced pluripotent stem cell (iPSC) models of β-myosin heavy chain and myosin-binding protein C3 mutations, and studied iPSC-derived cardiomyocytes in cardiac microtissue assays that resemble cardiac architecture and biomechanics. All HCM mutations resulted in hypercontractility with prolonged relaxation kinetics in proportion to mutation pathogenicity, but not changes in calcium handling. RNA sequencing and expression studies of HCM models identified p53 activation, oxidative stress, and cytotoxicity induced by metabolic …

Plasmodium Para-Aminobenzoate Synthesis And Salvage Resolve Avoidance Of Folate Competition And Adaptation To Host Diet, Joachim Michael Matz, Mutsumi Watanabe, Mofolusho Falade, Takayuki Tohge, Rainer Hoefgen, Kai Matuschewski

Pharmaceutical Sciences Faculty Publications

Folate metabolism is essential for DNA synthesis and a validated drug target in fast-growing cell populations, including tumors and malaria parasites. Genome data suggest that Plasmodium has retained its capacity to generate folates de novo. However, the metabolic plasticity of folate uptake and biosynthesis by the malaria parasite remains unresolved. Here, we demonstrate that Plasmodium uses an aminodeoxychorismate synthase and an aminodeoxychorismate lyase to promote the biogenesis of the central folate precursor para-aminobenzoate (pABA) in the cytoplasm. We show that the parasite depends on de novo folate synthesis only when dietary intake of pABA by …

Functional And Structural Studies Of Tolloid-Like 1 Mutants Associated With Atrial-Septal Defect 6., Lukasz Sieron, Marta Lesiak, Izabela Schisler, Zofia Drzazga, Andrzej Fertala, Aleksander L. Sieron

Department of Orthopaedic Surgery Faculty Papers

Inactive mammalian tolloid-like 1 (tll1) and mutations detected in tolloid-like 1 (TLL1) have been linked to the lack of the heart septa formation in mice and to a similar human inborn condition called atrial-septal defect 6 (ASD6; OMIM 613087, formerly ASD II). Previously, we reported four point mutations in TLL1 found in approximately 20% of ASD6 patients. Three mutations in the coding sequence were M182L, V238A, and I629V. In this work, we present the effects of these mutations on TLL1 function. Three recombinant cDNA constructs carrying the mutations and one wild-type construct were prepared and then expressed in HT-1080 cells. …

Choline Is An Intracellular Messenger Linking Extracellular Stimuli To Ip3-Evoked Ca2+ Signals Through Sigma-1 Receptors, Eugen Brailoiu, Sumita Chakraborty, G. Cristina Brailoiu, Pingwei Zhao, Jeffrey L. Barr, Marc A. Ilies, Ellen M. Unterwald, Mary E. Abood, Colin W. Taylor

College of Pharmacy Faculty Papers

Sigma-1 receptors (Sig-1Rs) are integral ER membrane proteins. They bind diverse ligands, including psychoactive drugs, and regulate many signaling proteins, including the inositol 1,4,5-trisphosphate receptors (IP₃Rs) that release Ca²⁺ from the ER. The endogenous ligands of Sig-1Rs are unknown. Phospholipase D (PLD) cleaves phosphatidylcholine to choline and phosphatidic acid (PA), with PA assumed to mediate all downstream signaling. We show that choline is also an intracellular messenger. Choline binds to Sig-1Rs, it mimics other Sig-1R agonists by potentiating Ca²⁺ signals evoked by IP₃Rs, and it is deactivated by metabolism. Receptors, by stimulating PLC and …

Disruption Of The Hippocampal And Hypothalamic Blood-Brain Barrier In A Diet-Induced Obese Model Of Type Ii Diabetes: Prevention And Treatment By The Mitochondrial Carbonic Anhydrase Inhibitor, Topiramate, Therese S. Salameh, William G. Mortell, Aric F. Logsdon, D. Allan Butterfield, William A. Banks

Chemistry Faculty Publications

Background: Type II diabetes is a vascular risk factor for cognitive impairment and increased risk of dementia. Disruption of the blood–retinal barrier (BRB) and blood–brain barrier (BBB) are hallmarks of subsequent retinal edema and central nervous system dysfunction. However, the mechanisms by which diet or metabolic syndrome induces dysfunction are not understood. A proposed mechanism is an increase in reactive oxygen species (ROS) and oxidative stress. Inhibition of mitochondrial carbonic anhydrase (mCA) decreases ROS and oxidative stress. In this study, topiramate, a mCA inhibitor, was examined for its ability to protect the BRB and BBB in diet-induced obese type II …

HLA typing in solid organ transplantation (SOT) is necessary for determining HLA-matching status between donor-recipient pairs and assessing patients' anti-HLA antibody profiles. Histocompatibility has traditionally been evaluated based on serologically defined HLA antigens. The evolution of HLA typing and antibody identification technologies, however, has revealed many limitations with using serologic equivalents for assessing compatibility in SOT. The significant improvements to HLA typing introduced by next-generation sequencing (NGS) require an assessment of the impact of this technology on SOT. We have assessed the role of high-resolution 2-field HLA typing (HR-2F) in SOT by retrospectively evaluating NGS-typed pre- and post-SOT cases. HR-2F …

Financial Barriers And Utilization Of Medical Services In Prison: An Examination Of Co-Payments, Personal Assets, And Individual Characteristics, Brian R. Wyant Phd, Holly M. Harner

Journal for Evidence-based Practice in Correctional Health

Although research has found that requiring incarcerated individuals to pay fees for medical service decreases use, there are still important unanswered questions about this association: 1) Is the copayment fee a barrier to those seeking medical attention? 2) If so, what individual factors are associated with viewing the copayments as the reason to avoid seeing a medical professional? Using 2012 survey data collected from 45 incarcerated persons housed in a maximum security prison on the East Coast, it was discovered that over 70% of the men surveyed reported avoiding medical services at least once in the past three months due …
