In diesem Artikel soll einer der strittigen Vertreter der deutschen Romantik auf zwei verschiedene Weisen analysiert werden, erstens durch Untersuchung des historischen Rahmens seiner antiken Tragödie "Penthesilea", und zweitens, durch den Vergleich des Werkes mit seiner persöhnlichen romantischen Veranlagung, um die traditionellen und historischen Grenzen des Begriffs "Romantik" zu erweitern.
"Wie ein ungeheures Märchen" : Johann Caspar, Johann Wolfgang und August Goethe im Petersdom in Rom
(2006)
Die Baugeschichte des Petersdoms in Rom, wie er sich dem Blick des neuzeitlichen Betrachters darstellt, ist das Resultat eines großen Abbruchunternehmens ebenso wie eines gewaltigen Neubaus. Von „schöpferischer Zerstörung“ hat Horst Bredekamp mit Blick auf die Baugeschichte von Neu St. Peter in Rom seit 1506 gesprochen. Als Johann Wolfgang Goethe, den Spuren seines Vaters folgend, 1786 auf seiner „Hegire“ das antike Rom und den Petersdom erblickte und sich damit in die südliche Kunstwelt „initiiert“ fühlte, konnte er kaum einschätzen, dass sein Neubau der deutschen Litera-tursprache ein ähnlich gewaltiges und gewaltsames Abbruch- und Aufbauprojekt sein könnte, wie der sich über mehr als ein Jahrhundert erstreckende Neubau der Papstkirche in Rom. Die „römischen Glückstage“, deren Stimmung und Kunstgefühl sich Goethe noch 1829, bei der Edition des „Zweiten römischen Aufenthalts“, in die „kimmerischen“ Nächte des Nordens holte, versuchte sein Sohn August 1830 auch für sich zu reklamieren. Doch endete dessen zu spät unternommene Flucht in einer Tragödie. August von Goethe starb zehn Tage, nachdem er die Kuppel des Petersdoms im Glanz der Morgensonne gesehen hatte, an einem Schlaganfall in Rom. Von dem Schock, der ihn im November 1830 durch die Nachricht vom Tod des Sohnes ereilte, hat sich Johann Wolfgang Goethe nicht mehr erholt.
A floristic description is presented of the study sites of the Research Training Group “The role of biodi-versity for biogeochemical cycles and biotic interactions in temperate deciduous forests”. To investi-gate different aspects of plant biodiversity in Hainich National Park (Thuringia), deciduous forest stands with low, medium and high canopy tree species diversity were compared. The results of species richness and forest communities show that the research sites are characterised by a typical central European forest flora. Greater vascular plant species richness occurs with higher diversity of tree species. Six of altogether twelve research sites are assigned to the beech forest alliance (Galioodorati-Fagion), the second half belongs to the oak-hornbeam forest alliance (Carpinionbetuli). Suballiances within the Galioodorati-Fagion in the study area include the Galio-Fagetum and the Hordelymo-Fagetum. All Carpinionbetuli relevées are assigned to the suballiance Stellario-Carpinetum.
In November 2005, a survey was begun of the wells in and around Hagia Sophia Church in Istanbul. The long-term goal of the survey is the understanding of the function of the tunnels and the water systems used for Hagia Sophia and its surroundings during the Byzantine and the Ottoman periods. Alternate research methods, such as geophysical research, will be used in future surveys. The 2005 survey examined the channels that run from under the narthex and continue northwards and the southwards of the building as well as channels that run towards the atrium, hippodrome, and garden in the north. The survey resulted in the first photos of the well-bottoms in the history of Hagia Sophia.
Die Datenbank BioLIS wird durch die Universitätsbibliothek Johann Christian Senckenberg (Frankfurt/M.) kostenfrei online zur Verfügung gestellt. Sie weist deutsche biologische Zeitschriftenliteratur aus dem Zeit¬raum 1970 bis 1996 nach – damit ist BioLIS eine wesentliche Ergänzung zu der Datenbank „Biological Abstracts“. Die bibliografischen Angaben zu den nachgewiesenen Aufsätzen werden durch umfassende Schlagwörter und Namen behandelter Organismen ergänzt, so dass Spezialrecherchen insbesondere nach Literatur über bestimmte Organismen möglich sind.
Background: Experimental animal data show that protection against severe acute respiratory syndrome coronavirus (SARS-CoV) infection with human monoclonal antibodies (mAbs) is feasible. For an effective immune prophylaxis in humans, broad coverage of different strains of SARS-CoV and control of potential neutralization escape variants will be required. Combinations of virus-neutralizing, noncompeting mAbs may have these properties. Methods and Findings: Human mAb CR3014 has been shown to completely prevent lung pathology and abolish pharyngeal shedding of SARS-CoV in infected ferrets. We generated in vitro SARS-CoV variants escaping neutralization by CR3014, which all had a single P462L mutation in the glycoprotein spike (S) of the escape virus. In vitro experiments confirmed that binding of CR3014 to a recombinant S fragment (amino acid residues 318–510) harboring this mutation was abolished. We therefore screened an antibody-phage library derived from blood of a convalescent SARS patient for antibodies complementary to CR3014. A novel mAb, CR3022, was identified that neutralized CR3014 escape viruses, did not compete with CR3014 for binding to recombinant S1 fragments, and bound to S1 fragments derived from the civet cat SARS-CoV-like strain SZ3. No escape variants could be generated with CR3022. The mixture of both mAbs showed neutralization of SARS-CoV in a synergistic fashion by recognizing different epitopes on the receptor-binding domain. Dose reduction indices of 4.5 and 20.5 were observed for CR3014 and CR3022, respectively, at 100% neutralization. Because enhancement of SARS-CoV infection by subneutralizing antibody concentrations is of concern, we show here that anti-SARS-CoV antibodies do not convert the abortive infection of primary human macrophages by SARS-CoV into a productive one. Conclusions: The combination of two noncompeting human mAbs CR3014 and CR3022 potentially controls immune escape and extends the breadth of protection. At the same time, synergy between CR3014 and CR3022 may allow for a lower total antibody dose to be administered for passive immune prophylaxis of SARS-CoV infection.
Background While there is enough convincing evidence in childhood acute lymphoblastic leukemia (ALL), the data on the pre-natal origin in childhood acute myeloid leukemia (AML) are less comprehensive. Our study aimed to screen Guthrie cards (neonatal blood spots) of non-infant childhood AML and ALL patients for the presence of their respective leukemic markers. Methods We analysed Guthrie cards of 12 ALL patients aged 2–6 years using immunoglobulin (Ig) and T-cell receptor (TCR) gene rearrangements (n = 15) and/or intronic breakpoints of TEL/AML1 fusion gene (n = 3). In AML patients (n = 13, age 1–14 years) PML/RARalpha (n = 4), CBFbeta/MYH11 (n = 3), AML1/ETO (n = 2), MLL/AF6 (n = 1), MLL/AF9 (n = 1) and MLL/AF10 (n = 1) fusion genes and/or internal tandem duplication of FLT3 gene (FLT3/ITD) (n = 2) were used as clonotypic markers. Assay sensitivity determined using serial dilutions of patient DNA into the DNA of a healthy donor allowed us to detect the pre-leukemic clone in Guthrie card providing 1–3 positive cells were present in the neonatal blood spot. Results In 3 patients with ALL (25%) we reproducibly detected their leukemic markers (Ig/TCR n = 2; TEL/AML1 n = 1) in the Guthrie card. We did not find patient-specific molecular markers in any patient with AML. Conclusion In the largest cohort examined so far we used identical approach for the backtracking of non-infant childhood ALL and AML. Our data suggest that either the prenatal origin of AML is less frequent or the load of pre-leukemic cells is significantly lower at birth in AML compared to ALL cases.
