Expression of recombinant protein including an His-tag to facilitate purification for diagnosis of CCHF and Lassa Viruses

Cedergren, Linda January 2006 (has links)
Abstract Crimean-Congo Hemorrhagic Fever virus (CCHF) and Lassa virus are giving sources illness to humans. In addition to zoonotic transmission, CCHF and Lassa virus can spread from person to person. After a short incubation period, CCHF and Lassa virus infections are characterized by a sudden onset of high fever, chills, headache and cough just like flu. Even some people are vomiting and have diarrhoea. After a few days of illness hemorrhagic manifestations occur. Treatment options for CCHF and Lassa viruses are limited, and there is no vaccine available for use in humans. The purpose of the present study was to produce recombinant nucleocapsid protein of Lassavirus and CCHF virus including an aminoterminal His-tag by a Semliki Forest Virus Replicon (pSFV 4.2). The recombinant proteins are planned to be used in future development of diagnostic methods.

A Carnivalesque Perspective of Graham Swift's Last Orders

Willis, Catherine Jane 07 January 2009 (has links)
Graham Swifts novel Last Orders has yet to be viewed as containing carnivalesque elements as defined by Mikhail Bakhtin in Rabelais and His World. Through the examination of Bakhtins theory of the carnivalesque and through a corresponding close reading of Last Orders, this article details the carnivalesque nature of the locations visited by the characters in the narrative, of the grotesque incidents that occur in these locations, and of the narrative style and structure of the novel itself.

Resan till naturen och förlorade minnen : En analys av Uncle Boonmee Who Can Recall His Past Lives

Jonas, Leo-Jacques January 2012 (has links)
Filmen Uncle Boonmee Who Can Recall His Past Lives (2010) presenterar ett antal scener som är till synes orelaterade till filmens övergripande handling. Filmens titel antyder att dessa scener möjligen kan vara minnen ur titelkaraktärens tidigare liv, emellertid finns det ytters lite underlag för en sådan tolkning i själva filmen. Syftet blir därmed att närmare undersöka dessa scener, att söka tematiska kopplingar mellan dessa scener och filmen som helhet, samt att försöka komma fram till hur dessa scener kan ses arbeta med minnen.Laura U. Marks bok, The Skin of the Film (2000), har valts som underlag för den följande analysen i förhoppning att de tankar som läggs fram där skall kunna nyttjas för att tolka och diskutera de nämnda scenerna i filmen. I arbetet nyttjas därtill den metod som förespråkas av det hermeneutiska vetenskapsidealet för att erhålla kunskap.Arbetet visar på att filmen inte nödvändigtvis söker att gestalta minnen utan kan ses locka åskådaren till att minnas genom att presentera bilder som bäst förstås genom kroppslig inlevelse i bilden, kort sagt; filmen söker att aktivera åskådarens minne genom bilder med haptiska kvaliteter. Detta görs samtidigt som filmen ständigt återkommer till samma tema; resan till naturen. Åskådaren får alltså både bevittna filmens karaktärers resa och lockas till att själv uppleva detta utifrån sina egna minnen. Naturen är dock inte nödvändigtvis resans mål, filmen ses snarare försöka föra åskådaren till ett visst sinnestillstånd.

Einfluss des Histondeacetylase-Inhibitors 4-Phenylbutyrat auf das Wachstum des experimentell-induzierten Pankreaskarzinoms / Influence of the histone-deacetylase-inhibitor 4-phenylbutyrat on the growth of the experimental-induced pancreatic cancer

Friske, Alexandra 24 June 2015 (has links) (PDF)
Das Pankreaskarzinom bleibt trotz verbesserter Diagnose- und Therapiemöglichkeiten weiterhin eine Krankheit mit einer sehr schlechten Prognose und Lebenserwartung nach Diagnosestellung. Eine innovative Therapiemöglichkeit stellt eine Gruppe von Histondeacetylase-Inhibitoren dar, die einen direkten Einfluss auf die Regulation der Genexpression in Tumorzellen haben. Das Ziel der vorliegenden Arbeit bestand darin, die Wirkung des HDAC-Inhibitors 4-Phenylbutyrat auf Pankreaskarzinomzellen in-vitro und vor allem in-vivo zu untersuchen. Neben dem Einfluss auf die Zellproliferation in-vitro und in-vivo wurde in-vivo im subkutanen und orthotopen Tumormodell der Einfluss auf Tumorwachstum, Zellproliferation, Nekroseausbreitung, Regulation des Connexin 43 und Histonacetylierung im Tumorgewebe untersucht. Die Untersuchungen zeigen, dass 4-PB durch seinen hemmenden Effekt auf das Wachstum von Xenografttumoren und auf die Proliferation von Pankreastumorzellen sowie durch seine fördernde Wirkung auf die Expression von Connexin 43, Acetylierung von H4 und Bildung eine Pseudokapsel, ein potentiell wirksames Medikament bei der experimentellen Behandlung des Pankreaskarzinoms ist.

A services stack architectural model for the CUAHSI-HIS

Seppi, James Adam 14 February 2011 (has links)
The Hydrologic Information System Project of the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) has successfully created a large-scale prototype Hydrologic Information System (HIS). This system catalogs and provides access to over 23 million time series of hydrologic data, which are distributed across the United States at various academic, research, and governmental data providers. The service-oriented architecture that enables the HIS comprises distributed hydrologic data servers, a centralized series catalog, and various client software applications, and is supported by WaterML, a standardized language for transmission of hydrologic data. The current architectural model, termed the Network-Observations Model, of the HIS relies on a searchable central catalog of series metadata. Harvesting series metadata from large federal data providers, such as the USGS, EPA, and NCDC, has proven a laborious undertaking and involves custom database migration tools. This time-consuming harvesting task, coupled with a multitude of custom-coded solutions at the central series catalog has led to concerns with the long-term sustainability of the current architectural model. A new architectural model, termed the Services Stack Model, is proposed in this thesis. In the proposed model, a catalog of services metadata, rather than of series metadata is used to connect hydrologic data consumers with data providers. Internationally-recognized web service and data encoding standards, including the upcoming WaterML2.0 specification, from the Open Geospatial Consortium are used as the backbone of the new model. The proposed model will hopefully lead to greater acceptance of the CUAHSI-HIS, and result in increased sustainability and reduced maintenance of the system in the long-term. / text

Untersuchungen zur Eignung einer neuen GnRH-Variante zur Brunstinduktion bei pluriparen Sauen

Engl, Silke 12 November 2006 (has links) (PDF)
Das Ziel der vorliegenden Arbeit war es, die brunststimulierende Wirkung des synthetisch hergestellten Gonadorelin[5-His, 6-Asp, 7-Trp, 8-Lys] (International Nonproprietary Name: Peforelin), das in dem Präparat Maprelin® XP10 enthalten ist, bei abgesetzten pluriparen Sauen zu prüfen. Im ersten Versuchsabschnitt wurde die zweckmäßige Dosierung ermittelt. Im zweiten Versuchsabschnitt wurde die Wirkung von Maprelin® XP10 mit der einer eCG- und einer Placebobehandlung verglichen. Die Bedingungen waren für die Versuchstiere in beiden Versuchsabschnitten homogen (etwa vierter Wurf, Säugezeit vier Wochen, Brunstkontrolle zweimal täglich in Anwesenheit eines geschlechtsaktiven Ebers, zweimal täglich sonographische Ovaruntersuchung, duldungsorientierte Besamung einmal täglich). In der Dosisfindungsstudie, in die 88 Tiere einbezogen wurden, erwies sich die Dosierung von 150 µg Peforelin, 24 Stunden nach dem Absetzen appliziert, als zweckmäßig zur Brunststimulation. Andere getestete Varianten (100 µg 24 Stunden, 150 µg 0 Stunden, 150 µg 48 Stunden, 187,5 µg 24 Stunden, 255 µg 24 Stunden nach dem Absetzen) waren hierzu weniger geeignet. In der Untersuchung zur klinischen Wirksamkeit wurden die 313 einbezogenen Tiere in drei Gruppen aufgeteilt und erhielten 24 Stunden nach dem Absetzen pro Tier 150 µg Peforelin (Gruppe I), 800 IE eCG (Gruppe II) oder 2 ml physiologische NaCl-Lösung als Placebo (Gruppe III). Zur Befunderhebung an den Ovarien wurden die Tiere zweimal täglich sonographisch untersucht. Die Östrusrate nach der Peforelin-Behandlung war derjenigen nach eCG-Injektion gleichwertig (95,1 bzw. 96,3 %), beide waren der Placebobehandlung signifikant überlegen (80,6 %). In die weiteren Auswertungen wurden nur Tiere mit Brunstbeginn bis zum siebten Tag nach dem Absetzen einbezogen. Das Absetz-Östrus-Intervall betrug 100,5, 94,2 bzw. 104,1 Stunden in den Gruppen I, II bzw. III. In der Brunstdauer und dem Intervall vom Östrusbeginn bis zur Ovulation unterschieden sich die drei Gruppen nicht. Die durchschnittliche Follikelgröße war in allen drei Gruppen zum Zeitpunkt des Absetzens 4 mm und zum Zeitpunkt der ersten Duldung 6 mm. Die Ovulationen fanden sowohl nach eCG als auch nach Maprelin® XP10 zwischen dem Mittag des sechsten (13.00 h) und der Nacht des siebten Tages (1.00 h) nach dem Absetzen statt. Bei der sonographischen Trächtigkeitsuntersuchung in der vierten Woche post inseminationem waren 100,0, 99,0 bzw. 97,6 % in den Gruppen I, II bzw. III positiv. Die Trächtigkeitsrate betrug 96,9, 97,1 bzw. 91,6 % in den Gruppen I, II bzw. III. Die Abferkelrate ergab 92,2, 93,4 und 73,8 % in den Gruppen I, II und III. Das Abferkelergebnis war in allen drei Gruppen gleich (11,7, 12,0 bzw. 11,6 insgesamt geborene Ferkel in den Gruppen I, II bzw. III). Es wurde eine negative Korrelation zwischen der Dauer des Absetz-Östrus-Intervalls und der Brunstdauer bzw. dem Intervall vom Östrusbeginn bis zur Ovulation nachgewiesen. Darüber hinaus korrelierten die Brunstdauer und das Intervall Östrusbeginn bis Ovulation positiv miteinander. In allen drei Gruppen stand die Follikelgröße bei der ersten Duldung in positiver Korrelation mit der Länge des Absetz-Östrus-Intervalls. Nach längerer Säugezeit kamen die Sauen tendenziell und in der Gruppe I signifikant früher in die Brunst als nach kürzerer Laktation. Weitere überprüfte potentielle Einflussfaktoren hatten weder auf den Brunsteintritt noch auf die erzielten Wurfgrößen oder andere Parameter Auswirkungen. Mit der vorliegenden Untersuchung wurde erstmals die Wirksamkeit des synthetisch hergestellten Peforelin zur Brunststimulation bei abgesetzten pluriparen Sauen nachgewiesen. Inwieweit das Präparat für diese Indikation auch bei primiparen Sauen oder Jungsauen wirksam eingesetzt werden kann, bleibt weiteren klinischen Prüfungen vorbehalten.

Implicações da adoção de processos construtivos tradicionais na produção de habitações de interesse social em larga escala

Fidelis, Vanessa Rosa Pereira 09 December 2011 (has links)
In the mid-sixties there was a boom in civil construction and at that moment it was possible to observe a considerable increase in the activities in this area. Similarly, we currently witness an important period in civil construction in Brazil, in which a great amount of investment was made by the Federal Government, allowing the construction of large-scale in all the national territory, principally of the Social Interest Dwellings (SID). This overview demonstrated that the constructive methods have to be developed for the completion of the chronograms, the improving of the quality and the reduction of environmental impact. However, as well as in previous decades, great part of the systems adopted in Brazil still refer to traditional construction processes and, according to what was determined by CAIXA, they are called conventional processes, that is, performed with constructive systems that have already been regulated. In the Triangulo Mineiro region is not different, great part of the constructions of the SID refer to the conventional way, executed with structures and foundations in reinforced concrete, ceramic blocks of masonry sealing, mortared coating in a single layer and wood covering structures with ceramic tiles. The point is that the conventional systems normally have a series of deficiencies related to the conception of the product, the insufficient project detailing and the enormous dependency on the knowledge of the labor execution workers. The pattern establishing is clearly difficult, together with the high level of labor using and the consequent low level of mechanization; the bad quality of some materials, principally the ones resulted from the direct nature extraction; and mostly, the incomplete projects and the inexistence of planning, do not permit the civil construction to be executed, practically speaking, in a rational way. Therefore, the reason why so many companies that construct the SID choose the traditional processes is questioned, even knowing that it is necessary to reach a more sustainable production in terms of the environment, increase the quality and the productivity in construction. This way, it is necessary to turn the attention to the improvement of quality and the rising of the industrialization level of the traditional constructive processes, which still represent a great part of the market, as well as the search of implementation of non-conventional constructive processes. Due to this demand, this work presents the analysis of the implications of adopting such processes in the execution of the SID in large scale, through the analysis of projects, procedures and losses in the productive process of a one-story-dwellings enterprise, executed in the city of Uberlandia, aiming the rationalization to obtain better results in quality and less generation of waste. / Em meados dos anos sessenta, houve um boom na construção civil e naquele momento pôde-se observar um aumento considerável nas atividades do setor. Do mesmo modo, atualmente presencia-se um período importante da construção civil no Brasil, no qual uma grande quantidade de recursos foi liberada pelo Governo Federal, o que permitiu a construção em larga escala, em todo o território nacional, principalmente das Habitações de Interesse Social (HIS). Esse panorama mostrou que os métodos construtivos precisaram ser aprimorados para o cumprimento dos cronogramas, o aperfeiçoamento da qualidade e a redução do impacto ambiental. Entretanto, assim como em décadas anteriores, a maioria dos sistemas adotados no Brasil ainda refere-se a processos tradicionais de construção e, segundo definido pela CAIXA são chamados de processos convencionais, ou seja, executados com sistemas construtivos que já possuem normalização. Na região do Triângulo Mineiro não é diferente, a maior parte das construções de HIS referem-se à forma convencional, executados com estruturas e fundações em concreto armado, alvenarias de vedação de blocos cerâmicos, revestimentos argamassados em camada única e estruturas de coberturas em madeira e telhas cerâmicas. O fato é que os sistemas convencionais, normalmente possuem uma série de deficiências relacionadas à concepção do produto, ao detalhamento insuficiente de projetos e da grande dependência do conhecimento da mão de obra que executa os serviços. A dificuldade de padronização é inerente, juntamente com o alto grau de utilização de mão de obra e o conseqüente pequeno nível de mecanização; a má qualidade de alguns materiais, principalmente aqueles fruto de extração direta da natureza; e, sobretudo os projetos incompletos e a inexistência de planejamentos, não permitem que, na prática, a construção civil seja executada de forma racionalizada. Deste modo, questiona-se porque a maioria das empresas construtoras de HIS optam por processos tradicionais de construção, mesmo sabendo que é necessário atingir uma produção mais sustentável ambientalmente, aumentar a qualidade e a produtividade na construção. Assim, torna-se necessário, além da busca pela implantação de processos construtivos não-convencionais, voltar a atenção para a melhoria da qualidade e elevação do grau de industrialização dos processos construtivos tradicionais, que continuam representando grande parcela do mercado. Diante desta demanda, o presente trabalho apresenta a análise das implicações da adoção de tais processos na execução de HIS em larga escala, por meio da análise de projetos, procedimentos e perdas no processo produtivo de um empreendimento de habitações térreas executado na cidade de Uberlândia, com foco na racionalização para obtenção de melhores resultados na qualidade e menor geração de resíduos. / Mestre em Engenharia Civil
