Das neue digitale ‚Shakespeare-Bildarchiv Oppel-Hammerschmidt‘ an der Universitätsbibliothek Mainz : Reden und Beiträge anlässlich seiner öffentlichen Vorstellung am 17. November 2008 an der Johannes Gutenberg-Universität Mainz

On the basis of illustrations of Shakespeare's Hamlet, the new digital 'Oppel-Hammerschmidt Shakespeare Illustration Archive' at the Mainz University Library - together with a lavishly-constructed and multiply-linked Web interface version - was presented to the public on 17 November 2008. This e-book, edited by Andreas Anderhub and Hildegard Hammerschmidt-Hummel, contains the speeches and presentations given on the occasion of the opening ceremony of the electronic archive. The collection of the new archive, published here for the first time, holds about 3,500 images and is part of the only Shakespeare illustration archive in the world. The Shakespeare Illustration Archive was founded in 1946 by the internationally acclaimed Shakespeare and Goethe scholar, Prof. Horst Oppel. This part of the archive was donated to the Mainz University Library on condition that its holdings be digitalised and made available to the public. The collection has been named 'The Oppel-Hammerschmidt Shakespeare Illustration Archive' in accordance with the terms of the Agreement of Donation of 9, 15, and 16 September 2005, and honouring the 16 March 1988 Delegation of Authority and Declaration of Intent by Frau Ingeborg Oppel, Prof. Oppel's widow and legal assignee. Vice-President Prof. Jürgen Oldenstein opened the proceedings by noting that 2008 had been a good year for international Shakespeare scholarship. For, in London, the site of the 'Theatre' in Shoreditch, where Shakespeare's company performed, had been unearthed, and in Mainz the Shakespeare Archive had gone online with thousands of illustrations. The Dean of the Faculty of Philosophy and Philology, Prof. Mechthild Dreyer, who mentioned that she herself had long been successfully employing interdisciplinary research methods, took particular pleasure in the transdisciplinary approach to research resolutely pursued by Prof. Hammerschmidt-Hummel. Prof. Clemens Zintzen (Cologne), former President of the Mainz Academy of Literature and Sciences, recalled highlights from the more than sixty-year-long history of the Shakespeare Illustration Archive. Prof. Kurt Otten (Heidelberg and Cambridge) drew an impressive portrait of Horst Oppel's personality as an academic and praised his influential books on Goethe and Shakespeare. He pointed out that Oppel's Shakespeare Illustration Archive, the basis for many a dissertation, had enjoyed great popularity around the world. Prof. Otten also delineated the academic career of Prof. Hammerschmidt-Hummel and her new findings regarding Shakespeare's time, life and work. Prof. Rüdiger Ahrens OBE (Würzburg) drew attention to Prof. Hammerschmidt-Hummel's research results, directly or indirectly arising out of her work on the Shakespeare Illustration Archive. This research had centred on proving the authenticity of four visual representations of Shakespeare (the Chandos and Flower portraits, the Davenant bust and the Darmstadt Shakespeare death mask); solving the mystery around Shakespeare's 'Dark Lady'; and establishing the dramatist's Catholic religion. Prof. Hammerschmidt-Hummel reported on her 'Shakespeare Illustration' project, describing the nature, dimensions and significance of the Archive's pictorial material, which relates to all of Shakespeare's plays and stretches over five centuries. She explained that the digital 'Oppel-Hammerschmidt Illustration Archive' was an addition to the three-volume edition she had compiled, authored and edited for publication in 2003. Unlike the print version, however, the digital collection had only been partly editorially prepared. It represented source material and a basis for further work. Hammerschmidt-Hummel expressed her thanks to the Head of the Central University Library, Dr Andreas Anderhub, for his untiring commitment. After the initial donation had been made, he had entered enthusiastically into setting up the necessary contacts, getting all the work underway, and clearing the legal hurdles. Hammerschmidt-Hummel was especially grateful to University of Mainz librarian Heike Geisel, who had worked for nearly five years to carry out the large-scale digitalization of a total of 8,800 items. Frau Geisel was also extremely resourceful in devising ways of making the collection yield even more, e.g. by classifying and cross-linking the data, assembling clusters of individual topics that lend themselves to research, and (in collaboration with the art historian Dr Klaus Weber) making the archive's index of artists compatible with the data-bank of artists held by the University of Mainz Institute of Art History. In addition, she compiled an extremely helpful 'users' guide' to the new digital collection. Frau Geisel had enjoyed invaluable support from Dr Annette Holzapfel-Pschorn, the leading academic in the Central IT Department at the University, who set up an intelligent, most impressive Web interface using the latest application technologies. Frau Geisel and Dr Holzapfel-Pschorn were highly praised for their convincing demonstration, using illustrations to Hamlet, of how to access this well-devised and exceptionally user-friendly Web version. For legal reasons, Prof. Hammerschmidt-Hummel pointed out, the collection could not be released for open access on the internet. The media - as Dr Anderhub stressed in his foreword - had shown great interest in the new digital collection of thousands of Shakespearean illustrations (cf. Benjamin Cor's TV feature in "Tagesthemen", 17 November 2008, presented by Tom Buhrow). The ‘Oppel-Hammerschmidt Shakespeare Illustration Archive’ should also meet with particular interest not only among academic specialists, but also among the performers of the arts and persons active in the cultural realm in general, as well as theatre and film directors, literary managers, teachers, and countless Shakespeare enthusiasts.

Analyse der Beteiligung von Toll-like-Rezeptoren an der DC-Aktivierung nach Parvovirus-H-1-Infektion

Ziel dieser Dissertation war es die funktionelle Rolle der Toll-like Rezeptoren (TLRs) und ihrer Signalwege bei der Aktivierung von dendritischen Zellen (DC) durch Parvovirus H-1- rn(H-1PV) induzierte Tumorzelllysate (TCL) zu untersuchen. rnDas angeborene Immunsystem bekämpft die Bildung und das Wachstum von Tumoren, insbesondere durch Interaktion von Effektor-Immunzellen mit Tumorzellen. Die Aktivierung dieser Immunreaktionen in der Antitumortherapie ist wünschenswert, aber in vielen Situationen nicht zufriedenstellend, da sie durch klassische systemische Therapie allein nicht immer erreicht werden kann. Die therapeutische Anwendung von onkolytischen Viren bei Patienten mit malignen Erkrankungen (Virotherapie) ist ein vielversprechendes Gebiet der Forschung. Die onkosuppressive und immunstimulierende Wirkung von H-1PV auf humane Tumor- und Immunzellen spricht für eine Verwendung in der Krebstherapie. Ein Aktivierung des Immunsystems durch H-1PV konnte bereits in unserer Arbeitsgruppe gezeigt werden.rnIn dieser Arbeit wurden wichtige Aspekte bezüglich der Aktivierung von Toll-like Rezeptoren bei einer H-1PV Infektion untersucht. Zunächst wurde die Rolle von TLRs nach der H-1PV Infektion untersucht. Humane embryonale Nierenzellen (HEK293) wurden stabil mit humanen TLRs transfiziert, um die Rolle spezifischer TLRs während der Aktivierung des Immunsystems zu untersuchen. TLR3 und TLR9 wurden durch eine H-1PV Infektion, die mit der NFκB-Translokation in den Zellkern korreliert, aktiviert. Mit Hilfe eines Reporterplasmides (pNiFty-Luc), wurde durch erhöhte Expression eines NFκB-induzierbaren Reportergens die NFκB-Aktivität im Anschluss an eine H-1PV Infektion nachgewiesen. Zudem wurde die immunologische Wirkung von H-1PV-induzierten Tumorzelllysaten (TCL) auf die humane antitumor-gerichtete Immunantworten analysiert. Ein humanes ex vivo-Modell, bestehend aus einer HLA-A2-positiven humanen Melanom-Zelllinie (SK29Mel) wurde verwendet, um Immunreaktionen mit entsprechenden HLA-restringierten humanen DCs zu untersuchen. DCs die mit H-1PV-infizierten SK29Mel Zellen koinkubiert wurden, zeigten eine erhöhte TLR3- und TLR9-Expression. Diese Daten deuten darauf hin, dass H-1PV-induzierte TCLs humane DCs stimulieren und dies zumindest teilweise durch TLR-abhängige Signalwege geschieht. Demnach wird eine DC-Reifung durch Kokultur mit H-1PV-induzierten TCLs über den TLR-Signalweg erreicht und führte u.a. zu einer NFκB-abhängigen Aktivierung des adaptiven Immunsystems. Die onkolytischen Virotherapie mit H-1PV erhöht so durch unterschiedliche Auswirkungen auf DCs die Immunreaktion und verstärkt die Anti-Tumor-Immunität. Diese Ergebnisse zeigen einen neuen potenziellen Ansatz für den Einsatz onkolytischer Viren für TLR-zielgerichtete Therapieoptionen und stellen eine ideale Möglichkeit zur Erweiterung der Krebsbehandlung dar.rn

Elektrochemische Desoxygenierung von Carbonsäureamiden und verwandten Verbindungen an der dekorierten Bleikathode

Zusammenfassung der Dissertation, Carolin Edinger, April 2015. Im Rahmen der Dissertation ist eine effiziente und zuverlässige Methode zur elektrochemischen Desoxygenierung von aromatischen Carbonsäureamiden entwickelt worden (Schema 1).[1] Unter galvanostatischen Bedingungen eignet sich das optimierte Elektrolytsystem bestehend aus 2%iger methanolischer H2SO4 und geringen Mengen an Additiv 1 in Kombination mit einer Bleikathode hervorragend in dem gewählten geteilten Zellaufbau. Schema 1: Elektrochemische Desoxygenierung aromatischer Carbonsäureamide. Untersuchungen an verschiedensten Amidsubstraten haben gezeigt, dass ein breites Spektrum an Aminen mit dieser Methode zugänglich ist und durch umfangreiche Studien konnten optimale Elektrolyseparameter gefunden werden. Außerdem wurde die Hochskalierung der Ansatzgröße an einem Testsubstrat mit hohen Aminausbeuten von bis zu 73% gewährleistet. Ein besonderes Merkmal der entwickelten Synthese ist neben milden Bedingungen und hoher Selektivität die Verwendung von Ammoniumsalzadditiven. Der positive Effekt dieser Additive auf die Desoxygenierungsreaktion ist vielfältig: Die Wasserstoffentwicklung als unerwünschte Nebenreaktion wird zu negativeren Potentialen verschoben und die Bleikathode wird durch Zurückdrängung der PbSO4-Bildung effektiv vor Korrosion geschützt. Dies konnte durch experimentelle Werte wie die Erhöhung der Produkt- und Stromausbeute durch Additivzusatz während der Elektrolyse hinreichend bestätigt werden. Aber auch zyklovoltammetrische Untersuchungen und Lichtmikroskopaufnahmen der Elektrodenoberfläche bekräftigen eindeutig diese Aussagen.[2,3] Die entwickelte elektrochemische Methode konnte zusätzlich erfolgreich auf Verbindungen übertragen werden, die mit Carbonsäureamiden verwandt sind. So gelang es, aromatische und aliphatische Sulfoxide in sehr guten Ausbeuten selektiv zu den entsprechenden Sulfiden umzusetzen. Zusätzlich konnten bereits bei weiteren, durch klassische Methoden schwer reduzierbare Stoffklassen erste Erfolge erzielt werden. So gelang es, den Grundstein zur Reduktion von Estern und Triphenylphosphinoxid zu legen und erste, vielversprechende Ergebnisse zu erlangen. Da Elektronen als Reduktionsmittel eingesetzt werden und lediglich Wasser als Nebenprodukt gebildet wird, zeichnet sich die entwickelte Desoxygenierungsmethode vor allem durch milde Bedingungen und hohe Selektivität aus. Da weder Reagenzien noch Katalysatoren verwendet werden müssen, werden Abfälle vermieden. Dadurch ist die gefundene Reduktionsmethode nicht nur kostengünstig, sondern erweist sich auch in der Reaktionsführung als vorteilhaft. Literatur: [1] C. Edinger, S. R. Waldvogel, Eur. J. Org.

Incidence, predictive factors, and prognosis of chondrosarcoma in patients with Ollier disease and Maffucci syndrome: an international multicenter study of 161 patients

Enchondromatosis is characterized by the presence of multiple benign cartilage lesions in bone. While Ollier disease is typified by multiple enchondromas, in Maffucci syndrome these are associated with hemangiomas. Studies evaluating the predictive value of clinical symptoms for development of secondary chondrosarcoma and prognosis are lacking. This multi-institute study evaluates the clinical characteristics of patients, to get better insight on behavior and prognosis of these diseases.

[First detection of "Candidatus Mycoplasma haemolamae" in South American Camelids of Switzerland and evaluation of prevalence]

Haemotrophic mycoplasmas (also known as haemoplasmas), small bacterias which parasite the surface of erythrocytes, have been described in several species. Recently, molecular methods were developed for the diagnosis of haemoplasma infection. The presented study describes the first detection and the investigation of prevalence of "Candidatus Mycoplasma haemolamae" in South American Camelids in Switzerland. A random sample of the latter population was tested for haemoplasma infections using real-time PCR. The infection was detected in 18.6% of the animals and was found both in indigenous and in imported camelids. Of the tested herds 39,1% harboured at least one animal positive for haemoplasmas in PCR. There was no difference in prevalence between male and female animals and llamas and alpacas, respectively. Furthermore, the prevalence of infection was not significantly different in diseased animals compared to healthy camelids. From the latter observation and the fact that the high prevalence was accompanied by an undetectable incidence, we concluded that the pathogenicity of "Candidatus Mycoplasma haemolamae" may be low.

National Values and Theatrical Values. The Battle of the Siege de Calais (1765)

This article underscores the complex relationship between national concerns and dramatic criticism by interrogating the role of theatre in the creation of a 'national culture' during the last few decades of the Ancien regime. The author focuses more specifically on the forms of patriotism proposed by Pierre-Laurent De Belloy, author of Le Siege de Calais, France's "first tragedy in which the nation is given the pleasure to take an interest in itself," as well as by his adversaries and his allies. The version of patriotism proffered by De Belloy - a 'fatherland' that he defines as both bourgeois and monarchical - renders problematic several aesthetic and political norms in place in 1765. The author thus responds modestly to one of the most essential questions posed by research on eighteenth-century political and cultural history: how did patriotism operate before the French Revolution?

A high-resolution soil erosion risk map of Switzerland as strategic policy support system

Soil erosion models and soil erosion risk maps are often used as indicators to assess potential soil erosion in order to assist policy decisions. This paper shows the scientific basis of the soil erosion risk map of Switzerland and its application in policy and practice. Linking a USLE/RUSLE-based model approach (AVErosion) founded on multiple flow algorithms and the unit contributing area concept with an extremely precise and high-resolution digital terrain model (2 m × 2 m grid) using GIS allows for a realistic assessment of the potential soil erosion risk, on single plots, i.e. uniform and comprehensive for the agricultural area of Switzerland (862,579 ha in the valley area and the lower mountain regions). The national or small-scale soil erosion prognosis has thus reached a level heretofore possible only in smaller catchment areas or single plots. Validation was carried out using soil loss data from soil erosion damage mappings in the field from long-term monitoring in different test areas. 45% of the evaluated agricultural area of Switzerland was classified as low potential erosion risk, 12% as moderate potential erosion risk, and 43% as high potential erosion risk. However, many of the areas classified as high potential erosion risk are located at the transition from valley to mountain zone, where many areas are used as permanent grassland, which drastically lowers their current erosion risk. The present soil erosion risk map serves on the one hand to identify and prioritise the high-erosion risk areas, and on the other hand to promote awareness amongst farmers and authorities. It was published on the internet and will be made available to the authorities in digital form. It is intended as a tool for simplifying and standardising enforcement of the legal framework for soil erosion prevention in Switzerland. The work therefore provides a successful example of cooperation between science, policy and practice.

A randomized, blinded, multicenter trial of lipid-associated amphotericin B alone versus in combination with an antibody-based inhibitor of heat shock protein 90 in patients with invasive candidiasis

BACKGROUND: Mycograb (NeuTec Pharma) is a human recombinant monoclonal antibody against heat shock protein 90 that, in laboratory studies, was revealed to have synergy with amphotericin B against a broad spectrum of Candida species. METHODS: A double-blind, randomized study was conducted to determine whether lipid-associated amphotericin B plus Mycograb was superior to amphotericin B plus placebo in patients with culture-confirmed invasive candidiasis. Patients received a lipid-associated formulation of amphotericin B plus a 5-day course of Mycograb or placebo, having been stratified on the basis of Candida species (Candida albicans vs. non-albicans species of Candida). Inclusion criteria included clinical evidence of active infection at trial entry plus growth of Candida species on culture of a specimen from a clinically significant site within 3 days after initiation of study treatment. The primary efficacy variable was overall response to treatment (clinical and mycological resolution) by day 10. RESULTS: Of the 139 patients enrolled from Europe and the United States, 117 were included in the modified intention-to-treat population. A complete overall response by day 10 was obtained for 29 (48%) of 61 patients in the amphotericin B group, compared with 47 (84%) of 56 patients in the Mycograb combination therapy group (odds ratio [OR], 5.8; 95% confidence interval [CI], 2.41-13.79; P<.001). The following efficacy criteria were also met: clinical response (52% vs. 86%; OR, 5.4; 95% CI, 2.21-13.39; P<.001), mycological response (54% vs. 89%; OR, 7.1; 95% CI, 2.64-18.94; P<.001), Candida-attributable mortality (18% vs. 4%; OR, 0.2; 95% CI, 0.04-0.80; P = .025), and rate of culture-confirmed clearance of the infection (hazard ratio, 2.3; 95% CI, 1.4-3.8; P = .001). Mycograb was well tolerated. CONCLUSIONS: Mycograb plus lipid-associated amphotericin B produced significant clinical and culture-confirmed improvement in outcome for patients with invasive candidiasis.
