Vom Posteingang bis in das Archiv. Technische und organisatorische Konzepte des ArchiSig-Projekts

Die digitale Speicherung von Informationen nimmt in öffentlichen wie privaten Verwaltungen einen immer größeren Stellenwert ein. Daher müssen sich Archive schon frühzeitig an der Implementierung von Dokumentenmanagementsystemen beteiligen, um auch in Zukunft historisch wertvolle digitale Unterlagen an kommende Generationen in authentischer Form weitergeben zu können. Unter dem Titel „Digitales Verwalten - Digitales Archivieren“ veranstaltete das Staatsarchiv Hamburg am 27. und 28. April 2004 die achte Tagung des Arbeitskreises „Archivierung von Unterlagen aus digitalen Systemen“. In ihm sind Archivare aus Staats- und Kommunalarchiven, aus Wirtschafts- und Kirchenarchiven Deutschlands, Österreichs und der Schweiz vertreten. Der archivische Umgang mit digitalen Unterlagen, die Erhaltung der Authentizität und die Langzeitspeicherung elektronischer Signaturen sind die bestimmenden Themen der 16 Beiträge, die in diesem Band dokumentiert sind.Digital storage of information is becoming increasingly important in public and private administration. Archives must therefore participate at an early stage in the implementation of content management systems in order to be able to pass on historically valuable digital documents to future generations in an authentic form. The eighth conference of the working group "Archiving of documents from digital systems" was organised by the Hamburg State Archives on 27 and 28 April 2004 under the title "Digital administration - digital archiving". It includes archivists from state and municipal archives, business and church archives in Germany, Austria and Switzerland. The archival handling of digital documents, the preservation of authenticity and the long-term storage of electronic signatures are the defining themes of the 16 contributions documented in this volume

Update on Endoscopic Treatment of Chronic Pancreatitis

Endoscopic therapy has been increasingly recognized as the effective therapy in selected patients with chronic pancreatitis. Utility of endotherapy in various conditions occurring in chronic pancreatitis is discussed. Its efficacy, limitations, and alternatives are addressed. For the best management of these complex entities, a multidisciplinary approach involving expertise in all pancreatic specialties is essential to achieve the goal

Update on Endoscopic Management of Main Pancreatic Duct Stones in Chronic Calcific Pancreatitis

Pancreatic duct stones are a common complication during the natural course of chronic pancreatitis and often contribute to additional pain and pancreatitis. Abdominal pain, one of the major symptoms of chronic pancreatitis, is believed to be caused in part by obstruction of the pancreatic duct system (by stones or strictures) resulting in increasing intraductal pressure and parenchymal ischemia. Pancreatic stones can be managed by surgery, endoscopy, or extracorporeal shock wave lithotripsy. In this review, updated management of pancreatic duct stones is discussed

Endoscopic Therapy in Chronic Pancreatitis

Chronic pancreatitis (CP) is a debilitating disease that can result in chronic abdominal pain, malnutrition, and other related complications. The main aims of treatment are to control symptoms, prevent disease progression, and correct any complications. A multidisciplinary approach involving medical, endoscopic, and surgical therapy is important. Endoscopic therapy plays a specific role in carefully selected patients as primary interventional therapy when medical measures fail or in patients who are not suitable for surgery. Endoscopic therapy is also used as a bridge to surgery or as a means to assess the potential response to pancreatic surgery. This review addresses the role of endoscopic therapy in relief of obstruction of the pancreatic duct (PD) and bile du ct, closure of PD leaks, and drainage of pseudocysts in CP. The role of endoscopic ultrasound-guided celiac plexus block for pain in chronic pancreatitis is also discussed

Nationale Forschungsdateninfrastruktur für die Ingenieurwissenschaften (NFDI4Ing)

NFDI4Ing ist ein 2017 gegründetes Konsortium mit dem Ziel, Wissenschaftler:innen aller Disziplinen zu ermöglichen, ingenieurwissenschaftliche Forschungsprozesse in ihrer Gesamtheit nachvollziehen oder reproduzieren zu können. Die Besonderheit an NFDI4Ing ist der Aufbau, welcher sich in drei Bereiche aufteilt. Die Archetypen, die an den methodischen Bedarfen ausgerichtet sind, die Community Cluster und die Base Services. NFDI4Ing erarbeitet technologische Methoden und Lösungen, bietet Aus- und Weiterbildungsprogramme und trägt zur Verbreitung des Forschungsdatenmanagements (FDM) in den Ingenieurwissenschaften bei

New Implications on Genomic Adaptation Derived from the Helicobacter pylori Genome Comparison

BACKGROUND: Helicobacter pylori has a reduced genome and lives in a tough environment for long-term persistence. It evolved with its particular characteristics for biological adaptation. Because several H. pylori genome sequences are available, comparative analysis could help to better understand genomic adaptation of this particular bacterium. PRINCIPAL FINDINGS: We analyzed nine H. pylori genomes with emphasis on microevolution from a different perspective. Inversion was an important factor to shape the genome structure. Illegitimate recombination not only led to genomic inversion but also inverted fragment duplication, both of which contributed to the creation of new genes and gene family, and further, homological recombination contributed to events of inversion. Based on the information of genomic rearrangement, the first genome scaffold structure of H. pylori last common ancestor was produced. The core genome consists of 1186 genes, of which 22 genes could particularly adapt to human stomach niche. H. pylori contains high proportion of pseudogenes whose genesis was principally caused by homopolynucleotide (HPN) mutations. Such mutations are reversible and facilitate the control of gene expression through the change of DNA structure. The reversible mutations and a quasi-panmictic feature could allow such genes or gene fragments frequently transferred within or between populations. Hence, pseudogenes could be a reservoir of adaptation materials and the HPN mutations could be favorable to H. pylori adaptation, leading to HPN accumulation on the genomes, which corresponds to a special feature of Helicobacter species: extremely high HPN composition of genome. CONCLUSION: Our research demonstrated that both genome content and structure of H. pylori have been highly adapted to its particular life style

John Farnbacher interview for The Survivors of the Holocaust Oral History Project

On August 7th, 1984, Julie Orenstein interviewed John Farnbacher about his life before, during, and after World War II. In his interview Farnbacher details his early childhood and education in Augsburg, Bavaria, his parents education and careers, and other family history. Farnbacher also discusses how his family came to Dayton as well as how his background in engineering and language skills helped him get a job at Wright Patterson Air Force Base during the war

Arf6 Can Trigger Wave Regulatory Complex-Dependent Actin Assembly Independent of Arno

The small GTPase ADP-ribosylation factor 6 (Arf6) anchors at the plasma membrane to orchestrate key functions, such as membrane trafficking and regulating cortical actin cytoskeleton rearrangement. A number of studies have identified key players that interact with Arf6 to regulate actin dynamics in diverse cell processes, yet it is still unknown whether Arf6 can directly signal to the wave regulatory complex to mediate actin assembly. By reconstituting actin dynamics on supported lipid bilayers, we found that Arf6 in co-ordination with Rac1(Ras-related C3 botulinum toxin substrate 1) can directly trigger actin polymerization by recruiting wave regulatory complex components. Interestingly, we demonstrated that Arf6 triggers actin assembly at the membrane directly without recruiting the Arf guanine nucleotide exchange factor (GEF) ARNO (ARF nucleotide-binding site opener), which is able to activate Arf1 to enable WRC-dependent actin assembly. Furthermore, using labelled E. coli, we demonstrated that actin assembly by Arf6 also contributes towards efficient phagocytosis in THP-1 macrophages. Taken together, this study reveals a mechanism for Arf6-driven actin polymerization
