Teschen Disease (Teschovirus Encephalomyelitis) Eradication in Czechoslovakia: a Historical Report
Historical Report Veterinarni Medicina, 54, 2009 (11): 550–560 Teschen disease (Teschovirus encephalomyelitis) eradication in Czechoslovakia: a historical report V. Kouba* Prague, Czech Republic ABSTRACT: Teschen disease (previously also known as Klobouk’s disease), actually called Teschovirus encepha- lomyelitis, is a virulent fatal viral disease of swine, characterized by severe neurological disorders of encephalomy- elitis. It was initially discovered in the Teschen district of North-Eastern Moravia. During the 1940s and 1950s it caused serious losses to the pig production industry in Europe. The most critical situation at that time, however, was in the former Czechoslovakia. A nationally organized eradication programme started in 1952. That year the reported number of new cases of Teschen disease reached 137 396, i.e., an incidence rate of 2 794 per 100 000 pigs, in 14 801 villages with 65 597 affected farms, i.e., 4.43 affected farms per village and 2.10 diseased pigs per affected farm. The average territorial density of new cases was 1.07 per km2. For etiological diagnosis histological investigation of the central nervous system, isolation of virus and seroneutralization were used. Preventive meas- ures consisted in feeding pigs with sterilized waste food and in ring vaccination. Eradication measures took the form of the timely detection and reporting of new cases, isolating outbreak areas, and the slaughter of intrafocal pigs followed by sanitation measures. Diseased pigs were usually destroyed in rendering facilities. The carcasses of other intrafocal pigs were treated as conditionally comestible, i.e., only after sterilization. During the years 1952–1965 from a reported 537 480 specifically diseased pigs 36 558 died; i.e., Teschen disease mortality rate was 6.80% while other intrafocal pigs (88.12%) were urgently slaughtered. -

For this review, we identified over twenty types of human cancer that have been modeled in the mouse using Sleeping Beauty and piggyBac transposon insertion mutagenesis. We examine several specific biological insights that have been gained and describe opportunities for continued research. Specifically, we review studies with a focus on understanding metastasis, therapy resistance, and tumor cell of origin. Additionally, we propose further uses of transposon-based models to identify rarely mutated driver genes across many cancers, understand additional mechanisms of drug resistance and metastasis, and define personalized therapies for cancer patients with obesity as a comorbidity. Keywords: animal modeling; cancer; transposon screen 1. Transposon Basics Until the mid of 1900’s, DNA was widely considered to be a highly stable, orderly macromolecule neatly organized into chromosomes. -

REVIEW ARTICLE Functional studies of the coronavirus nonstructural proteins Yanglin QIU and Kai XU* Jiangsu Key Laboratory for Microbes and Functional Genomics, College of Life Sciences, Nanjing Normal University, Nanjing 210023, P. R. China. *Correspondence: [email protected] https://doi.org/10.37175/stemedicine.v1i2.39 ABSTRACT Coronaviruses, including SARS-CoV, SARS-CoV-2, and MERS-CoV, have caused contagious and fatal respiratory diseases in humans worldwide. Notably, the coronavirus disease 19 (COVID-19) caused by SARS-CoV-2 spread rapidly in early 2020 and became a global pandemic. The nonstructural proteins of coronaviruses are critical components of the viral replication machinery. They function in viral RNA transcription and replication, as well as counteracting the host innate immunity. Studies of these proteins not only revealed their essential role during viral infection but also help the design of novel drugs targeting the viral replication and immune evasion machinery. In this review, we summarize the functional studies of each nonstructural proteins and compare the similarities and differences between nonstructural proteins from different coronaviruses. Keywords: Coronavirus · SARS-CoV-2 · COVID-19 · Nonstructural proteins · Drug discovery Introduction genes (18). The first two major ORFs (ORF1a, ORF1ab) The coronavirus (CoV) outbreaks among human are the replicase genes, and the other four encode viral populations have caused three major epidemics structural proteins that comprise the essential protein worldwide, since the beginning of the 21st century. These components of the coronavirus virions, including the spike are the epidemics of the severe acute respiratory syndrome surface glycoprotein (S), envelope protein (E), matrix (SARS) in 2003 (1, 2), the Middle East respiratory protein (M), and nucleocapsid protein (N) (14, 19, 20). -

Understanding Human Astrovirus from Pathogenesis to Treatment Abstract While human astroviruses (HAstV) were discovered nearly 45 years ago, these small positive-sense RNA viruses remain critically understudied. These studies provide fundamental new research on astrovirus pathogenesis and disruption of the gut epithelium by induction of epithelial-mesenchymal transition (EMT) following astrovirus infection. Here we characterize HAstV-induced EMT as an upregulation of SNAI1 and VIM with a down regulation of CDH1 and OCLN, loss of cell-cell junctions most notably at 18 hours post-infection (hpi), and loss of cellular polarity by 24 hpi. While active transforming growth factor- (TGF-) increases during HAstV infection, inhibition of TGF- signaling does not hinder EMT induction. However, HAstV-induced EMT does require active viral replication. -
Leukocyte Cytoskeleton Polarization Is Initiated by Plasma Membrane Curvature from Cell Attachment
Article Leukocyte Cytoskeleton Polarization Is Initiated by Plasma Membrane Curvature from Cell Attachment Graphical Abstract Authors Chunguang Ren, Qianying Yuan, Martha Braun, ..., Erdem Karatekin, Wenwen Tang, Dianqing Wu Correspondence [email protected] (E.K.), [email protected] (W.T.), [email protected] (D.W.) In Brief The molecular mechanisms controlling cell polarization are incompletely understood. Ren and Yuan et al. show that local increase in plasma membrane (PM) curvature resulting from cell attachment recruits and polarizes an inverse FBAR domain protein SRGAP2 to initiate cell cytoskeleton polarization, which is important for neutrophil adhesion to endothelium. Highlights d Cell attachment is required for chemical-induced cytoskeleton polarization d Cell attachment induces local PM curvature increase to recruit and polarize SRGAP2 d Polarized SRGAP2 induces sequential polarization of PtdIns4P, PIP5K1C90, and pMLC d This SRGAP2 polarization signaling axis regulates neutrophil firm adhesion Ren et al., 2019, Developmental Cell 49, 1–14 April 22, 2019 ª 2019 Elsevier Inc. https://doi.org/10.1016/j.devcel.2019.02.023 Please cite this article in press as: Ren et al., Leukocyte Cytoskeleton Polarization Is Initiated by Plasma Membrane Curvature from Cell Attachment, Developmental Cell (2019), https://doi.org/10.1016/j.devcel.2019.02.023 Developmental Cell Article Leukocyte Cytoskeleton Polarization Is Initiated by Plasma Membrane Curvature from Cell Attachment Chunguang Ren,1,16 Qianying Yuan,1,16 Martha Braun,2,3,14 Xia -

A Scoping Review of Viral Diseases in African Ungulates
veterinary sciences Review A Scoping Review of Viral Diseases in African Ungulates Hendrik Swanepoel 1,2, Jan Crafford 1 and Melvyn Quan 1,* 1 Vectors and Vector-Borne Diseases Research Programme, Department of Veterinary Tropical Disease, Faculty of Veterinary Science, University of Pretoria, Pretoria 0110, South Africa; [email protected] (H.S.); [email protected] (J.C.) 2 Department of Biomedical Sciences, Institute of Tropical Medicine, 2000 Antwerp, Belgium * Correspondence: [email protected]; Tel.: +27-12-529-8142 Abstract: (1) Background: Viral diseases are important as they can cause significant clinical disease in both wild and domestic animals, as well as in humans. They also make up a large proportion of emerging infectious diseases. (2) Methods: A scoping review of peer-reviewed publications was performed and based on the guidelines set out in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews. (3) Results: The final set of publications consisted of 145 publications. Thirty-two viruses were identified in the publications and 50 African ungulates were reported/diagnosed with viral infections. Eighteen countries had viruses diagnosed in wild ungulates reported in the literature. (4) Conclusions: A comprehensive review identified several areas where little information was available and recommendations were made. It is recommended that governments and research institutions offer more funding to investigate and report viral diseases of greater clinical and zoonotic significance. A further recommendation is for appropriate One Health approaches to be adopted for investigating, controlling, managing and preventing diseases. Diseases which may threaten the conservation of certain wildlife species also require focused attention.
