    Joint Pathology Center Veterinary Pathology Services Wednesday Slide Conference 2013-2014 Conference 25 May 7, 2014 ______________________________________________________________________________ CASE I: 3121206023 (JPC 4035610). Signalment: 5-week-old mixed breed piglet, (Sus domesticus). History: Two piglets from the faculty farm were found dead, and another piglet was weak and ataxic and, therefore, euthanized. Gross Pathology: The submitted piglet was in good body condition. It was icteric and had a diffusely pale liver. Additionally, petechial hemorrhages were found on the kidneys, and some fibrin was present covering the abdominal organs. Laboratory Results: The intestine was PCR positive for porcine circovirus (>9170000). Histopathologic Description: Mesenteric lymph node: Diffusely, there is severe lymphoid depletion with scattered karyorrhectic debris (necrosis). Also scattered throughout the section are large numbers of macrophages and eosinophils. The macrophages often contain botryoid basophilic glassy intracytoplasmic inclusion bodies. In fewer macrophages, intranuclear basophilic inclusions can be found. Liver: There is massive loss of hepatocytes, leaving disrupted liver lobules and dilated sinusoids engorged with erythrocytes. The remaining hepatocytes show severe swelling, with micro- and macrovesiculation of the cytoplasm and karyomegaly. Some swollen hepatocytes have basophilic intranuclear, irregular inclusions (degeneration). Throughout all parts of the liver there are scattered moderate to large numbers of macrophages (without inclusions). Within portal areas there is multifocally mild to moderate fibrosis and bile duct hyperplasia. Some bile duct epithelial cells show degeneration and necrosis, and there is infiltration of neutrophils within the lumen. The limiting plate is often obscured mainly by infiltrating macrophages and eosinophils, and fewer neutrophils, extending into the adjacent parenchyma. Scattered are small areas with extra medullary hematopoiesis.

  • The Uber Board Deliberates: Is Good Governance Worth the Firing of an Entrepreneurial Founder? by BRUCE KOGUT *
    ID#190414 CU242 PUBLISHED ON MAY 13, 2019 The Uber Board Deliberates: Is Good Governance Worth the Firing of an Entrepreneurial Founder? BY BRUCE KOGUT * Introduction Uber Technologies, the privately held ride-sharing service and logistics platform, suffered a series of PR crises during 2017 that culminated in the resignation of Travis Kalanick, cofounder and longtime CEO. Kalanick was an acclaimed entrepreneur, building Uber from its local San Francisco roots to a worldwide enterprise in eight years, but he was also a habitual rule- breaker. 1 In an effort to put the recent past behind the company, the directors of Uber scheduled a board meeting for October 3, 2017, to vote on critical proposals from new CEO Dara Khosrowshahi that were focused essentially on one question: How should Uber be governed now that Kalanick had stepped down as CEO? Under Kalanick, Uber had grown to an estimated $69 billion in value by 2017, though plagued by scandal. The firm was accused of price gouging, false advertising, illegal operations, IP theft, sexual harassment cover-ups, and more.2 As Uber’s legal and PR turmoil increased, Kalanick was forced to resign as CEO, while retaining his directorship position on the nine- member board. His June 2017 resignation was hoped to calm the uproar, but it instead increased investor uncertainty. Some of the firm’s venture capital shareholders (VCs) marked down their Uber holdings by 15% (Vanguard, Principal Financial), while others raised the valuation by 10% (BlackRock).3 To restore Uber’s reputation and stabilize investor confidence, the board in August 2017 unanimously elected Dara Khosrowshahi as Uber’s next CEO.

  • 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.

The fastest pulsar and the slowest nova; the oldest galaxies and the youngest stars; the weirdest life forms and the commonest dwarfs; the highest energy particles and the lowest energy photons. These were some of the extremes of Astrophysics 2006. We attempt also to bring you updates on things of which there is currently only one (habitable planets, the Sun, and the universe) and others of which there are always many, like meteors and molecules, black holes and binaries.

  • Aagrapevine Youtube Channel
    AAGrapevine YouTube Channel In 2017, the General Service Conference recommended “that AA Grapevine create a Google for Nonprofits ac- count limited to the YouTube Nonprofit Program.” AA Grapevine, Inc. is currently displaying content on the channel, consistent with AA principles and copyrights. The channel was first populated with AAWS’ engaging, Conference-approved PSA: “Doors”, an animated version of a member’s recorded story for the GV Audio Project and two behind-the-scenes clips from the plant where the magazines are printed. We have since added a timeline of the making of our Big Book as well as a discussion from one of our non-alcoholic Class A Trustees on the use of AA Grapevine in CPC (Cooperation with the profes- sional Community) work. Expansion of the AA Grapevine YouTube collection is in process, with the ultimate goal of hosting video content that may be of use or interest to members, the general public and the professional community. The first series will fall under the umbrella of “Explainer Videos” that will serve to convey useful information on various topics with the purpose of streamlining access to multi-media content.

  • Sheep and Goats
    Sheep Pox and Importance Sheep pox and goat pox are contagious viral diseases of small ruminants. These Goat Pox diseases may be mild in indigenous breeds living in endemic areas, but they are often fatal in newly introduced animals. Economic losses result from decreased milk Capripoxvirus Infections, production, damage to the quality of hides and wool, and other production losses. Sheep Capripox pox and goat pox can limit trade, inhibit the development of intensive livestock production, and prevent new breeds of sheep or goats from being imported into endemic regions. Last Updated: August 2017 Etiology Sheep pox and goat pox result from infection by sheeppox virus (SPPV) or goatpox virus (GTPV), closely related members of the genus Capripoxvirus in the family Poxviridae. SPPV is mainly thought to affect sheep and GTPV primarily to affect goats, but some isolates can cause mild to serious disease in both species. SPPV and GTPV can be distinguished by a few specialized genetic tests. These tests are not widely available, and isolates are typically assigned to SPPV or GTPV based on the animal species affected during an outbreak. However, some studies suggest that this assumption is not always valid. SPPV and GTPV are closely related to lumpy skin disease virus (LSDV), a capripoxvirus that affects cattle. These three viruses cannot be distinguished by many diagnostic tests, including all tests that detect antibodies or viral antigens. Species Affected SPPV and GTPV only appear to affect sheep and goats. It seems plausible that these viruses could cause disease in wild relatives of small ruminants, but there are no reports of any infections in free-living or captive wild species.
