One of the unresolved questions in studies on population dynamics of forest Lepidoptera is why some populations at times reach outbreak densities, whereas others never do. Resolving this question is especially challenging if populations of the same species in different areas or of closely-related species in the same area are considered. The present study focused on three closely-related geometrid moth species, autumnal Epirrita autumnata, winter Operophtera brumata and northern winter moths Operophtera fagata, in southern Finland. There, winter and northern winter moth populations can reach outbreak densities, whereas autumnal moth densities stay relatively low. We tested the hypothesis that a lower vulnerability to pupal predation may explain the observed differences in population dynamics. The results obtained do not support this hypothesis because pupal predation probabilities were not significantly different between the two genera within or without the Operophtera outbreak area or in years with or without a current Operophtera outbreak. Overall, pupal predation was even higher in winter and northern winter moths than in autumnal moths. Differences in larval predation and parasitism, as well as in the reproductive capacities of the species, might be other candidates.
Background: Local adaptation to divergent environmental conditions can promote population genetic differentiation even in the absence of geographic barriers and hence, lead to speciation. Perturbations by catastrophic events, however, can distort such parapatric ecological speciation processes. Here, we asked whether an exceptionally strong flood led to homogenization of gene pools among locally adapted populations of the Atlantic molly (Poecilia mexicana, Poeciliidae) in the Cueva del Azufre system in southern Mexico, where two strong environmental selection factors (darkness within caves and/or presence of toxic H2S in sulfidic springs) drive the diversification of P. mexicana. Nine nuclear microsatellites as well as heritable female life history traits (both as a proxy for quantitative genetics and for trait divergence) were used as markers to compare genetic differentiation, genetic diversity, and especially population mixing (immigration and emigration) before and after the flood. Results: Habitat type (i.e., non-sulfidic surface, sulfidic surface, or sulfidic cave), but not geographic distance was the major predictor of genetic differentiation. Before and after the flood, each habitat type harbored a genetically distinct population. Only a weak signal of individual dislocation among ecologically divergent habitat types was uncovered (with the exception of slightly increased dislocation from the Cueva del Azufre into the sulfidic creek, El Azufre). By contrast, several lines of evidence are indicative of increased flood-induced dislocation within the same habitat type, e.g., between different cave chambers of the Cueva del Azufre. Conclusions: The virtual absence of individual dislocation among ecologically different habitat types indicates strong natural selection against migrants. Thus, our current study exemplifies that ecological speciation in this and other systems, in which extreme environmental factors drive speciation, may be little affected by temporary perturbations, as adaptations to physico-chemical stressors may directly affect the survival probability in divergent habitat types.
Background: To evaluate the effectivity of fractionated radiotherapy in adolescent and adult patients with pineal parenchymal tumors (PPT). Methods: Between 1982 and 2003, 14 patients with PPTs were treated with fractionated radiotherapy. 4 patients had a pineocytoma (PC), one a PPT with intermediate differentiation (PPTID) and 9 patients a pineoblastoma (PB), 2 of which were recurrences. All patients underwent radiotherapy to the primary tumor site with a median total dose of 54 Gy. In 9 patients with primary PB treatment included whole brain irradiation (3 patients) or irradiation of the craniospinal axis (6 patients) with a median total dose of 35 Gy. Results: Median follow-up was 123 months in the PC patients and 109 months in the patients with primary PB. 7 patients were free from relapse at the end of follow-up. One PC patient died from spinal seeding. Among 5 PB patients treated with radiotherapy without chemotherapy, 3 developed local or spinal tumor recurrence. Both patients treated for PB recurrences died. The patient with PPTID is free of disease 7 years after radiotherapy. Conclusion: Local radiotherapy seems to be effective in patients with PC and some PPTIDs. Diagnosis and treatment of patients with more aggressive variants of PPTIDs as well as treatment of PB need to be further improved, since local and spinal failure even despite craniospinal irradiation (CSI) is common. As PPT are very rare tumors, treatment within multi-institutional trials remains necessary.
The aim of this study is to assess the development of plant species diversity and species composition over a seven-year period in two calcareous grasslands abandoned for nearly 20 years and to find out which factors influence vegetation dynamics. In the Abava River valley, Latvia, different calcareous grasslands were studied, one on the south-west facing slope and another on the north-east facing slope. Vegetation analyses on permanent plots showed that dry calcareous grasslands can be resistant to deterioration for a long period of time – succession was slower than reported in many cases for Central and Western Europe. None of the studied communities showed a decrease neither in total species number recorded per community nor in average species richness per plot. Vascular plant species richness even increased by 3–4 species per 1-m2 plot in the grassland on the south-west facing slope. An unexpected result of the research was that Calamagrostis epigeios did not expand in this grassland. This fact can be explained by the influence of disturbances (drought, tree cutting) and local differences in soil parameters and topography. In parts of the north-east exposed grassland, with deeper soils and better water availability, species diversity (Shannon index) decreased significantly in areas overgrown by Aegopodium podagraria.
Background: Prospective, observational studies that enroll large numbers of patients with few exclusion criteria may better reflect actual ongoing clinical experience than randomized clinical trials. Our purpose was to obtain efficacy and safety information from a cohort of subjects exposed to latanoprost/timolol fixed combination (FC) for [greater than or equal to]18 months using a prospective, observational design. Methods: In all, 577 office-based ophthalmologists in Germany switched 2339 patients with glaucoma or ocular hypertension to latanoprost/timolol FC for medical reasons. Follow-up visits were scheduled for every 6 months over 24 months; physicians followed usual care routines. Intraocular pressure (IOP), visual field status, optic nerve head findings, and adverse events were recorded. Efficacy parameters were evaluated for the per protocol (PP) population; the safety population included subjects receiving [greater than or equal to]1 drop of FC. Physicians rated efficacy, tolerability, and subject compliance at month 24. Results: Of the 2339 subjects switched to latanoprost/timolol FC (safety population), the primary reasons for switching were inadequate IOP reduction (78.2%) and desire to simplify treatment with once-daily dosing (29.4%; multiple reasons possible). In all, 1317 (56.3%) subjects completed the study, and 1028 (44.0%) were included in the PP population. Most discontinuations were due to loss to follow-up. Change in mean IOP from baseline to month 6 was -4.0 +/- 4.31 mmHg, a reduction that was maintained throughout (P<0.05 for change at all time points). By investigator assessments, optic disc parameters and visual field were stable over 24 months, and there was no relationship between IOP reduction over 24 months and development of a visual field defect. More than 90% of physicians rated latanoprost/timolol FC as "very good" or "good" for efficacy (PP population), tolerability, and compliance. The FC was safe and well tolerated. No change in iris color was reported by most subjects (83.1%) at month 24. Conclusions: Over 24 months, latanoprost/timolol FC effectively lowers IOP levels and is well tolerated in patients with glaucoma or ocular hypertension who change from their previous ocular hypotensive therapy for medical reasons. Investigator assessments found optic disc parameters and visual field to be stable throughout 24 months of follow-up.
Los campañas de 2006, 2007 y 2008 en Alcorrín han puesto de manifiesto la importancia del lugar para los primeros contactos entre fenicios e indígenas en el extremo occidental de la provincia de Málaga, que las dataciones radiométricas han situado en la segunda mitad del siglo IX a.C. Este proyecto ha permitido documentar una imponente fortificación del Bronce Final, conocida con anterioridad sólo a nivel superficial. La realización de prospecciones geofísicas nos revela un incipiente urbanismo que irá siendo conocido en detalle en futuras actuaciones. Estos trabajos se han completado con la excavación de un edificio singular, de planta cuadrangular y compartimentada, con un pavimento de conchas en su acceso. Entre los materiales, escasos y mayoritariamente consistentes en cerámica a mano, cabe señalar la presencia de dos grafitos fenicios sobre cerámica.
Vier eigensinnige Alleingänger als Mitglieder einer Rockband mit mäßigem Erfolg; dass diese Kombination eine denkbar schlechte ist, zeigte die Trennung der US-Gruppe Pixies im Jahre 1992. Vier eigensinnige Alleingänger als Mitglieder einer Rockband mit großem Erfolg; dass auch diese Kombination eine denkbar schlechte ist, das zeigt der Film 'loudQUIETloud - A film about The Pixies' nach deren Wiedervereinigung im Jahre 2004. Die fast zwölf Jahre dazwischen, in denen Musiker wie David Bowie oder Placebo Pixies-Songs neu auflegten und Hollywood den Pixies-Sound für die Filmmusik entdeckte, haben die Band zwar zu einer einflussreichen Indierock-Bands gemacht, ihre vier Mitglieder aber nur kurzzeitig reicher und - jetzt filmisch belegt - keinesfalls reifer werden lassen.
The present approach deals with an almost forgotten aspect of the oevre of Ludwig Hesshaimer, primarily known and appreciated for his drawings. Hesshaimer is nowadays known for his drawings and paintings from World War I. He also was very well known at his time as president of the Austrian Association of Philatelists. This approach starts with a brief biography, presenting the historical and family background of Hesshaimer, in order to position his work into the literary and historical context of the time. The second part of the present text refers to his autobiographical book Miniaturen aus der Monarchie printed in 1992 under the supervision of Hesshaimers daughter and granddaughter. Then it focuses on the analysis of his three stories about artists that are considered of general interest because they are almost unknown being published just once in 1928. Applied to the most interesting story Der nackte Fuß (The naked foot) follows an analysis of the stylistic phenomenon known as ekphrasis, which is a literary description of works of art.
Le cadre du programme interdisciplinaire de recherche défini par Max Horkheimer dans les années 1930 doit beaucoup à Erich Fromm, qui a introduit la psychologie sociale dans la Théorie critique de la société. Or, une décennie plus tard, Fromm est la cible privilégiée des attaques et sa théorie apparaît désormais comme incompatible avec les positions défendues par Horkheimer et Adorno. Partant de ces tensions qui ont marqué l’histoire de l’École de Francfort, le présent article vise à éclaircir le déplacement qu’elles traduisent sur le plan épistémologique. Si Horkheimer et Fromm partagent des prémisses communes, le premier, dans son travail avec Adorno, se rapproche de manière croissante de la doctrine freudienne alors que le second s’en éloigne. Nous voudrions montrer que l’accord entre Fromm et Horkheimer fut surtout négatif puisqu’il portait sur la critique de Freud : les divergences entre les deux penseurs apparaissent clairement, dès lors qu’on pose en profondeur la question de l’usage de la psychanalyse pour analyser l’un des problèmes centraux de la théorie de la société, l’antagonisme entre individu et société.
Starting from Warburg, the distinguishing mark of an image, considered as identity-difference of visible and invisible, is its offering itself as an implementation of a temporality, and at the same time of a memory that is immanent in the sensible structure of the image. It’s what we find both in Benjamin and in Adorno: in both cases, it is just because the image is marked by a “internal time” that it is able to have a critical function towards reality, and at the same time an utopian character that is all the same with its non-renounceable testimonial task.
Background: The apoptosis-inducing serine protease granzyme B (GrB) is an important factor contributing to lysis of target cells by cytotoxic lymphocytes. Expression of enzymatically active GrB in recombinant form is a prerequisite for functional analysis and application of GrB for therapeutic purposes. Methods and Findings: We investigated the influence of bacterial maltose-binding protein (MBP) fused to GrB via a synthetic furin recognition motif on the expression of the MBP fusion protein also containing an N-terminal alpha-factor signal peptide in the yeast Pichia pastoris. MBP markedly enhanced the amount of GrB secreted into culture supernatant, which was not the case when GrB was fused to GST. MBP-GrB fusion protein was cleaved during secretion by an endogenous furin-like proteolytic activity in vivo, liberating enzymatically active GrB without the need of subsequent in vitro processing. Similar results were obtained upon expression of a recombinant fragment of the ErbB2/HER2 receptor protein or GST as MBP fusions. Conclusions: Our results demonstrate that combination of MBP as a solubility enhancer with specific in vivo cleavage augments secretion of processed and functionally active proteins from yeast. This strategy may be generally applicable to improve folding and increase yields of recombinant proteins.
The massive amount of genomic sequence data that is now available for analyzing evolutionary relationships among 31 placental mammals reduces the stochastic error in phylogenetic analyses to virtually zero. One would expect that this would make it possible to finally resolve controversial branches in the placental mammalian tree. We analyzed a 2,863,797 nucleotide-long alignment (3,364 genes) from 31 placental mammals for reconstructing their evolution. Most placental mammalian relationships were resolved, and a consensus of their evolution is emerging. However, certain branches remain difficult or virtually impossible to resolve. These branches are characterized by short divergence times in the order of 1-4 million years. Computer simulations based on parameters from the real data show that as little as about 12,500 amino acid sites could be sufficient to confidently resolve short branches as old as about 90 million years ago. Thus, the amount of sequence data should no longer be a limiting factor in resolving the relationships among placental mammals. The timing of the early radiation of placental mammals coincides with a period of climate warming some 100 - 80 million years ago and with continental fragmentation. These global processes may have triggered the rapid diversification of placental mammals. However, the rapid radiations of certain mammalian groups complicate phylogenetic analyses, possibly due to incomplete lineage sorting and introgression. These speciation-related processes led to a mosaic genome and conflicting phylogenetic signals. Split network methods are ideal for visualizing these problematic branches and can therefore depict data conflict and possibly the true evolutionary history better than strictly bifurcating trees. Given the timing of tectonics, of placental mammalian divergences, and the fossil record, a Laurasian rather than Gondwanan origin of placental mammals seems the most parsimonious explanation. Key words: continental drift , Cretaceous warming , genome analysis , hybridization , phylogenomics , split decomposition
Lipid rafts are specialized plasma membrane micro-domains highly enriched in cholesterol, sphingolipids and glycosylphosphatidylinositol (GPI) anchored proteins. Lipid rafts are thought to be located in the exofacial leaflet of plasma membranes. Functionally, lipid rafts are involved in intracellular trafficking of proteins and lipids, secretory and endocytotic pathways, signal transduction, inflammation and in cell-surface proteolysis. There has been substantial interest in lipid rafts in brain, both with respect to normal functioning and with certain neurodegenerative diseases. Based on the impact of lipid rafts on multitude biochemical pathways, modulation of lipid rafts is used to study related disease pathways and probably offers a target for pharmacological intervention. Lipid rafts can be targeted by modulation of its main components, namely cholesterol and sphingolipids. Other approaches include the modulation of membrane dynamics and it has been reported that protein-lipid interactions can vary the occurrence and composition of these membrane micro-domains. The present review summarizes the possibilities to modulate lipid rafts with focus on neuronal cells. Keywords: Lipid raft, cholesterol, membrane fluidity, statin, cyclodextrine, docosahexaenoic acid.
Max Dessoir
(2010)
Spécialiste d’esthétique philosophique et de psychologie, Max Dessoir (1867–1947) est un des principaux fondateurs de la Kunstwissenschaft. Élève de Wilhelm Dilthey, il fait des études de philosophie à Berlin, où en 1889 il soutient une thèse sur Karl Philipp Moritz. En 1892, il obtient un diplôme de médecine à Würzburg. En 1888, Dessoir fonde la « Gesellschaft für Experimental-Psychologie », dédiée à l’étude de l’hypnose et des phénomènes paranormaux. Il enseigne la philosophie à Berlin de 1897 à 1933. Suite à la montée du national-socialisme, il est d’abord privé de sa chaire à cause de ses origines juives, et, en 1936, interdit définitivement d’enseigner en Allemagne. Après la guerre, il occupe la chaire de philosophie à l’Université de Francfort. Dessoir dédie l’essentiel de ses travaux à l’étude des connexions entre arts et sciences. ...
Mit "Golden Age" bezeichnet man die Studioära im Hollywood der 30er und 40er Jahre mit ihrer streng hierarchischen Struktur und einer hoch spezialisierten Form der Arbeitsteilung. Produzenten, Regisseure, Drehbuchschreiber, der technische Stab, sowie Schauspieler, Musiker und auch die Komponisten waren fest angestellte Mitarbeiter, die ihren Dienst auf dem Studiogelände verrichteten. In den dreißiger Jahren hatten Warner Bros. Regisseure wie Michael Curtiz, Produzenten wie Hal Wallis, Schauspieler wie Humphrey Bogart, Erroll Flynn oder Bette Davis, sowie Komponisten wie Erich Wolfgang Korngold oder Max Steiner unter Vertrag. Diese beiden Komponisten werden zusammen mit Alfred Newman (musikalischer Leiter von 20th Century Fox) auch das Triumvirat der Filmmusik des Goldenen Zeitalters in Hollywood genannt.
While many different RNA aptamers have been identified that bind to a plethora of small molecules only very few are capable of acting as engineered riboswitches. Even for aptamers binding the same ligand large differences in their regulatory potential were observed. We address here the molecular basis for these differences by using a set of unrelated neomycin-binding aptamers. UV melting analyses showed that regulating aptamers are thermally stabilized to a significantly higher degree upon ligand binding than inactive ones. Regulating aptamers show high ligand-binding affinity in the low nanomolar range which is necessary but not sufficient for regulation. NMR data showed that a destabilized, open ground state accompanied by extensive structural changes upon ligand binding is important for regulation. In contrast, inactive aptamers are already pre-formed in the absence of the ligand. By a combination of genetic, biochemical and structural analyses, we identified a switching element responsible for destabilizing the ligand free state without compromising the bound form. Our results explain for the first time the molecular mechanism of an engineered riboswitch.
In diesem Kapitel werden alle Darstellungen zu diesem Themenkreis aus beiden Romanen gesammelt und interpretiert. Die medizingeschichtlichen Hintergründe sollen als erstes anhand der Figur des "Harfners" erläutert werden. [...] Goethes Beschreibung des Harfners bildet eines der Hauptelemente der Romanhandlung. An mehreren Stellen treten bei dieser Figur seelische Abgründe zutage, deren Ursache erst am Ende der Geschichte sichtbar wird. Einen ersten Hinweis liefert der Harfner, als er seinen Herrn Wilhelm um die Entbindung von seinen Pflichten bittet. Er sagt: "Mein Herr, lassen Sie mir mein schaudervolles Geheimnis, und geben Sie mich los! Die Rache, die mich verfolgt, ist nicht des irdischen Richters; ich gehöre einem unerbittlichen Schicksale."
Meeting people is easy

Als die britische Band 'Radiohead' 1997 den Filmemacher Grant Gee, der zuvor mit seiner Arbeit an U2s 'Zoo-TV Performance' und mit einigen Musikvideos für Aufsehen gesorgt hatte, als Dokumentarfilmer mit auf ihre Welt-Tournee zum Album "Ok Computer" nahm, wusste keiner der Beteiligten, wie diese verlaufen würde. Frühere Tourneen hatten sich allerdings zum Teil als sehr anstrengend für die Band erwiesen. Vor allem der Frontmann Thom Yorke litt immer wieder unter dem Tour-Alltag. Bedenken muss man zusätzlich, dass die Dokumentation nicht als Bericht über eine Erfolgstour geplant werden konnte, weil zu dem Zeitpunkt, an dem Gees Arbeit an "Meeting people is easy" startete, das Album selbst erst zeitgleich zum Film auf den Markt kam.

Metal-Filme
(2010)
Heavy Metal hat seinen Ursprung im Hard- und Bluesrock der 1960er und 1970er Jahre. Seine musikalischen Vorgänger sind Bands wie Led Zeppelin, Deep Purple und Iron Butterfly. Der Begriff taucht in der Musik erstmals 1968 auf, als Iron Butterfly ihrem Debütalbum den Titel 'Heavy' gaben und Steppenwolf in ihrem Song 'Born to be wild' über "heavy metal thunder" sangen. Die Entstehung des Ausdrucks ist jedoch unklar, sie wird unter anderem Jimi Hendrix zugeordnet, aber auch als Ausdruck für eine neue Musik, die härter ist als Hardrock – "Metall" (= metal) sei eben in der Realität härter als "Stein" (= rock) - angesehen. Als "Geburtsstunde" des Heavy Metal gilt allgemein der 13. Februar 1970. An diesem Tag erschien das selbst betitelte Debütalbum von Black Sabbath, die häufig als erste Metalband der Welt bezeichnet werden und deren Erfolg bis heute anhält.
Experimental results are presented for 180 in silico designed octapeptide sequences and their stabilizing effects on the major histocompatibility class I molecule H-2Kb. Peptide sequence design was accomplished by a combination of an ant colony optimization algorithm with artificial neural network classifiers. Experimental tests yielded nine H-2Kb stabilizing and 171 nonstabilizing peptides. 28 among the nonstabilizing octapeptides contain canonical motif residues known to be favorable for MHC I stabilization. For characterization of the area covered by stabilizing and non-stabilizing octapeptides in sequence space, we visualized the distribution of 100,603 octapeptides using a self-organizing map. The experimental results present evidence that the canonical sequence motives of the SYFPEITHI database on their own are insufficient for predicting MHC I protein stabilization.
Peroxisome proliferator-activated receptor γ (PPARγ) gained considerable interest as a therapeutic target during chronic inflammatory diseases. Remarkably, the pathogenesis of diseases such as multiple sclerosis or Alzheimer is associated with impaired PPARγ expression. Considering that regulation of PPARγ expression during inflammation is largely unknown, we were interested in elucidating underlying mechanisms. To this end, we initiated an inflammatory response by exposing primary human macrophages to lipopolysaccharide (LPS) and observed a rapid decline of PPARγ1 expression. Because promoter activities were not affected by LPS, we focused on mRNA stability and noticed a decreased mRNA half-life. As RNA stability is often regulated via 3′-untranslated regions (UTRs), we analyzed the impact of the PPARγ-3′-UTR by reporter assays using specific constructs. LPS significantly reduced luciferase activity of the pGL3-PPARγ-3′-UTR, suggesting that PPARγ1 mRNA is destabilized. Deletion or mutation of a potential microRNA-27a/b (miR-27a/b) binding site within the 3′-UTR restored luciferase activity. Moreover, inhibition of miR-27b, which was induced upon LPS exposure, partially reversed PPARγ1 mRNA decay, whereas miR-27b overexpression decreased PPARγ1 mRNA content. In addition, LPS further reduced this decay. The functional relevance of miR-27b-dependent PPARγ1 decrease was proven by inhibition or overexpression of miR-27b, which affected LPS-induced expression of the pro-inflammatory cytokines tumor necrosis factor α (TNFα) and interleukin (IL)-6. We provide evidence that LPS-induced miR-27b contributes to destabilization of PPARγ1 mRNA. Understanding molecular mechanisms decreasing PPARγ might help to better appreciate inflammatory diseases.
Introduction: Hypothermia improves survival and neurological recovery after cardiac arrest. Pro-inflammatory cytokines have been implicated in focal cerebral ischemia/reperfusion in-jury. It is unknown whether cardiac arrest also triggers the release of cerebral inflammatory molecules, and whether therapeutic hypothermia alters this inflammatory response. This study sought to examine whether hypothermia or the combination of hypothermia with anes-thetic postconditioning with sevoflurane affect cerebral inflammatory response after cardio-pulmonary resuscitation. Methods: Thirty pigs (28 - 34kg) were subjected to cardiac arrest following temporary coro-nary artery occlusion. After 7 minutes of ventricular fibrillation and 2 minutes of basic life support, advanced cardiac life support was started according to the current AHA guidelines. Return of spontaneous circulation was achieved in 21 animals who were randomized to ei-ther normothermia at 38degreesC, hypothermia at 33degreesC or hypothermia at 33degreesC combined with se-voflurane (each group: n = 7) for 24 hours. The effects of hypothermia and the combination of hypothermia with sevoflurane on cerebral inflammatory response after cardiopulmonary resuscitation were studied using tissue samples from the cerebral cortex of pigs euthanized after 24 hours and employing quantitative RT-PCR and ELISA techniques. Results: Global cerebral ischemia following resuscitation resulted in significant upregulation of cerebral tissue inflammatory cytokine mRNA expression (mean +/- SD; interleukin (IL)-1beta 8.7 +/- 4.0, IL-6 4.3 +/- 2.6, IL-10 2.5 +/- 1.6, tumor necrosis factor (TNF)alpha 2.8 +/- 1.8, intercellular adhesion molecule-1 (ICAM-1) 4.0 +/- 1.9-fold compared with sham control) and IL-1beta protein concentration (1.9 +/- 0.6-fold compared with sham control). Hypothermia was associated with a significant (P <0.05 versus normothermia) reduction in cerebral inflammatory cytokine mRNA expression (IL-1beta 1.7 +/- 1.0, IL-6 2.2 +/- 1.1, IL-10 0.8 +/- 0.4, TNFalpha 1.1 +/- 0.6, ICAM-1 1.9 +/- 0.7-fold compared with sham control). These results were also confirmed for IL-1beta on protein level. Experimental settings employing hypothermia in combination with sevoflurane showed that the volatile anesthetic did not confer additional anti-inflammatory effects com-pared with hypothermia alone. Conclusions: Mild therapeutic hypothermia resulted in decreased expression of typical ce-rebral inflammatory mediators after cardiopulmonary resuscitation. This may confer, at least in part, neuroprotection following global cerebral ischemia and resuscitation.
Um Dynamiken und Netzwerke in den untersuchten Clubszenen und urbanen Räumen Berlins wissenschaftlich erfassen zu können, bedarf es einer multidimensionalen Herangehensweise. Ethnografi sche Methoden sind dabei von größter Bedeutung: teilnehmende Beobachtung im Alltag sowie auf Veranstaltungen vor Ort, fokussierte Gespräche mit Szenegängern und reflektierende Berichte über die eigene Positionierung als Forscherin. Das gesammelte Datenmaterial ist vielfältig: detaillierte Feldnotizen nach jedem Club- oder Barbesuch, aber auch nach relevanten Gesprächen, sei es »face-to-face«, über E-Mail- oder Chatverkehr nehmen den größten Part ein. Bildmaterial wie Plakate, Flyer und selbst gemachte Fotos in Clubs ergänzen das Schriftmaterial auch visuell. Das Verfolgen stadt- und kulturpolitischer Entwicklungen, Beobachtungen sozioökonomischer Gegebenheiten in den jeweiligen Szenen und der Einfl uss urbaner Infrastruktur auf das Ausgehverhalten sind weitere Mosaiksteine, die dazu beitragen, ein möglichst ganzheitliches Bild entstehen zu lassen. Nach der Feldforschungs- und Datenerhebungsphase wird das gesamte Datenmaterial ab Januar 2011 einer qualitativen Analyse unterzogen.
Mit Kuppel und Minarett? Häufig wird die Frage nach der Form einer Moschee als Stellvertreterfrage nach der Akzeptanz des Islam wahrgenommen. Doch könnten offene Diskussionen über die Gestaltung neuer Moscheen auch einen Weg zur funktionierenden Zivilgesellschaft darstellen, ohne dass Muslime und Nichtmuslime ihr eigenes Profil aufgeben müssen.
Due to an increasing awareness of the potential hazardousness of air pollutants, new laws, rules and guidelines have recently been implemented globally. In this respect, numerous studies have addressed traffic-related exposure to particulate matter using stationary technology so far. By contrast, only few studies used the advanced technology of mobile exposure analysis. The Mobile Air Quality Study (MAQS) addresses the issue of air pollutant exposure by combining advanced high-granularity spatial-temporal analysis with vehicle-mounted, person-mounted and roadside sensors. The MAQS-platform will be used by international collaborators in order 1) to assess air pollutant exposure in relation to road structure, 2) to assess air pollutant exposure in relation to traffic density, 3) to assess air pollutant exposure in relation to weather conditions, 4) to compare exposure within vehicles between front and back seat (children) positions, and 5) to evaluate "traffic zone"- exposure in relation to non-"traffic zone"-exposure. Primarily, the MAQS-platform will focus on particulate matter. With the establishment of advanced mobile analysis tools, it is planed to extend the analysis to other pollutants including including NO2, SO2, nanoparticles, and ozone.
The eukaryotic glyoxalase system consists of two enzymatic components, glyoxalase I (lactoylglutathionelyase) and glyoxalase II (hydroxyacylglutathione hydrolase). These enzymes are dedicated to the removal of toxic alpha-oxoaldehydes like methylglyoxal (MG). MG is formed as a by-product of glycolysis and MG toxicity results from its damaging capability leading to modifications of proteins, lipids and nucleic acids. An efficient removal of MG appears to be essential to ensure cellular functionality and viability. Here we study the effects of the genetic modulation of genes encoding the components of the glyoxalase system in the filamentous ascomycete and aging model Podospora anserina. Overexpression of PaGlo1 leads to a lifespan reduction on glucose rich medium, probably due to depletion of reduced glutathione. Deletion of PaGlo1 leads to hypersensitivity against MG added to the growth medium. A beneficial effect on lifespan is observed when both PaGlo1 and PaGlo2 are overexpressed and the corresponding strains are grown on media containing increased glucose concentrations. Notably, the double mutant has a ‘healthy’ phenotype without physiological impairments. Moreover, PaGlo1/PaGlo2_OEx strains are not long-lived on media containing standard glucose concentrations suggesting a tight correlation between the efficiency and capacity to remove MG within the cell, the level of available glucose and lifespan. Overall, our results identify the up-regulation of both components of the glyoxalase system as an effective intervention to increase lifespan in P. anserina. Key words: Podospora anserina, aging, lifespan, glycation, glucose, methylglyoxal, advanced glycation end products
Monterey Pop
(2010)
Der ästhetisch ambitionierte und kommerziell erfolgreiche Dylanfilm DONT LOOK BACK, den Pennebaker 1967 produziert hatte, machte die Produzenten des First International Monterey Pop Festivals auf den Dokumentaristen aus der Direct-Cinema-Gruppe um Robert Drew aufmerksam. Allerdings hatte er noch nie einen wirklichen Konzertfilm gemacht – in DONT LOOK BACK lag der thematische Schwerpunkt auf Dylan und nicht auf seiner Musik –, geschweige denn ein ganzes Festival verfilmt. In MONTEREY POP lässt Pennebaker die Interpreten die Geschichte des Festivals durch ihre Musik erzählen, ohne dass viele Worte verloren werden. Getreu seinem Filmstil vermied er erneut jegliche Erläuterungen übergeordneter Erzähler. Dennoch orientierte sich der Verlauf des Filmes an dem Festivalmitorganisator John Philipps und seinen Mamas and Papas als Headliner des Festivals. Eigentlich waren Pennebakers Aufnahmen für ein TV-Special konzipiert. Festival-Co-Produzent Lou Adler zufolge erkannte Pennebaker jedoch mehr in dem Material, ging darum schon in der Planung über den ursprünglichen Rahmen hinaus.
Die Parallelen zwischen Cortázars 'Rayuela' und Musils 'Mann ohne Eigenschaften' wurden von wissenschaftlicher Seite schon mehrfach untersucht. Die Frage, ob und inwieweit sich die Berührungspunkte der Romane auf einen direkten Einfluss Musils zurückführen lassen, ist dabei weitgehend ausgeklammert geblieben. Einen ersten Schritt dahingehend soll hier durch die Aufarbeitung von Umständen und Umfang von Cortázars Musil-Rezeption, die bisher ebenso wenig beachtet wurde, getan werden. Ein weiterer Schritt ist die Analyse von Kontext und Funktion, die den Nennungen Musils in 'Rayuela' zukommt. Die im Zuge der Rezeptionsaufarbeitung durch die Durchsicht von Cortázars Exemplaren der Musilschen Werke gewonnenen Kenntnisse über jene Passagen, die ihm bedeutend erschienen sein dürften, erleichtern es außerdem, Musilsche Intertexte in 'Rayuela' aufzuspüren, die als Indiz eines Einflusses gewertet werden können. Dass es davon mehr gibt, als bisher angenommen, soll an einer exemplarischen Analyse des 71. Kapitels von 'Rayuela' verdeutlicht werden.
The Ucayali River originates in the high Andean Mountains near the city of Cusco in Peru. After about 1,600 km, it joins with the Marañón River. Both the Ucayali River and the Marañón River are sources of the Amazon. From 2001 to 2005, the Ministry of Transport and Communication of Peru funded a study to determine the navigability of the Ucayali River. In the process, an extensive data set was acquired including hydrological and sedimentological data as well as a comprehensive topographical survey of the riverbed. Since the Ucayali River has experienced no stream channel modification in the past, the available data provide information about the flow pattern for a natural stream and insight into a reference ecosystem. This paper offers the first analysis of the available data and a sediment transport calculation for the Ucayali River.
Mit Mount St. Elias. Die längste Skiabfahrt der Welt. ist Mitte November ein Ski- und Bergfilm in den deutschen Kinos angelaufen, der schon jetzt als einer der meistgesehenen Dokumentarfilme der österreichischen Kinogeschichte gilt. Auch in Deutschland wurde der Film als Bergfilm angekündigt, der neue Maßstäbe setze. Dieser Kommentar beschäftigt sich mit den dramaturgischen Bausteinen des Erfolgs von Mount St. Elias und legt besonderes Augenmerk auf die Inszenierungsstrategien des ,Dokumentarischen‘ im Kontext des alpinen Diskurses.
MTV Unplugged
(2010)
Wenn ein Fernsehsender eine Konzertreihe als „Königsklasse der Musikwelt” ausgibt und einen Auftritt in ihr als „Ritterschlag” für jeden Künstler bezeichnet, neigt man dazu, diese Superlative als schamlose Prahlerei abzutun. Die Konzertreihe MTV UNPLUGGED, die im Videotext des Senders MTV mit ebendiesen Attributen beworben wird, kann auf eine mehr als zwanzigjährige Tradition zurückblicken, in deren Verlauf sich das Format nicht nur zur bekanntesten Konzertreihe der Fernsehgeschichte entwickelt hat, sondern unplugged auch zur Bezeichnung für Auftritte mit akustischen Instrumenten im allgemeinen wurde. Es war die Intimität des Auftritts, deren Eindruck sich bei den Konzerten einstellte, der die allgemeine Bekanntheit begründete.
Introduction: Amniotic fluid harbors cells indicative of all three germ layers, and pluripotent fetal amniotic fluid stem cells (AFSs) are considered potentially valuable for applications in cellular therapy and tissue engineering. We investigated whether it is possible to direct the cell fate of AFSs in vivo by transplantation experiments into a particular microenvironment, the mammary fat pad. This microenvironment provides the prerequisites to study stem cell function and the communication between mesenchymal and epithelial cells. On clearance of the endogenous epithelium, the ductal tree can be reconstituted by the transfer of exogenously provided mammary stem cells. Analogously, exogenously provided stem cells from other tissues can be investigated for their potential to contribute to mammary gland regeneration. Methods: We derived pluripotent murine AFSs, measured the expression of stem cell markers, and confirmed their in vitro differentiation potential. AFSs were transplanted into cleared and non cleared fat pads of immunocompromised mice to evaluate their ability to assume particular cell fates under the instructive conditions of the fat-pad microenvironment and the hormonal stimulation during pregnancy. Results: Transplantation of AFSs into cleared fat pads alone or in the presence of exogenous mammary epithelial cells caused their differentiation into stroma and adipocytes and replaced endogenous mesenchymal components surrounding the ducts in co-transplantation experiments. Similarly, transplantation of AFSs into fat pads that had not been previously cleared led to AFS-derived stromal cells surrounding the elongating endogenous ducts. AFSs expressed the marker protein α-SMA, but did not integrate into the myoepithelial cell layer of the ducts in virgin mice. With pregnancy, a small number of AFS-derived cells were present in acinar structures. Conclusions: Our data demonstrate that the microenvironmental cues of the mammary fat pad cause AFSs to participate in mammary gland regeneration by providing mesenchymal components to emerging glandular structures, but do not incorporate or differentiate into ductal epithelial cells.
Murray Lerner
(2010)
Murray Lerner ist als einer der erfindungsreichsten Dokumentaristen der Musik bekannt geworden - insbesondere der Film über die China-Tournee des Violinisten Isaac Stern (FROM MAO TO MOZART: ISAAC STERN IN CHINA, 1981, der mit dem Oscar ausgezeichnet wurde) fand weltweite Aufmerksamkeit. Lerner war jedoch auch für eine ganze Reihe von Rockumentaries verantwortlich - ein interviewbasiertes Porträt der Rock-Gruppe The Who (AMAZING JOURNEY: THE STORY OF THE WHO, 2007) sowie die Filme, die aus dem Material entstanden, das Lerner auf dem von mehr als 600.000 Besuchern frequentierten Isle of Wight Festival im August 1970 gedreht hatte - der Festivalfilm MESSAGE TO LOVE: THE ISLE OF WIGHT FESTIVAL (1997) ebenso wie ein Film über den legendären Auftritt Miles Davis‘ (MILES ELECTRIC: A DIFFERENT KIND OF BLUE, 2004), die Dokumentation des Auftritts der Gruppe The Who (LISTENING TO YOU: THE WHO AT THE ISLE OF WIGHT, 1970/1996) oder von Jimi Hendrix‘ Performance auf dem gleichen Festival (JIMI HENDRIX AT THE ISLE OF WIGHT, 1991) sowie der Auftritte von The Moody Blues, Emerson, Lake & Palmer und Leonard Cohen.
Die Musikindustrie hat mit den Jahren ihre Methoden, Musikstile und Bands maßgeschneidert in den Markt hinein zu produzieren, ja sogar Märkte künstlich zu produzieren, immer weiter verfeinert. Ebenso hat die Kritik an diesen Verfahren, Musikstile wie Moden in schnellem Wechsel aufeinander folgen zu lassen und dadurch Konsumbedürfnisse von Fans immer neu anzufachen, diese als 'synthetisch' verdammt - als stehe alledem ein 'natürliches' Prinzip gegenüber, nach dem sich neue Musikstile organisch aus den historischen und individuellen Erfahrungen von Musikern entwickelten.
Musik als ethische Disziplin : zu einem zentralen Aspekt in Augustins früher Schrift De musica
(2010)
Augustins frühe Schrift De musica ist neben Boethius’ De institutione musica und weiteren Äußerungen Augustins über Musik in anderen Schriften eine der zentralen Quellen für die Frühzeit der christlich-abendländischen Musikanschauung und hat diese bis in die Neuzeit hinein geprägt. Die sechs Bücher dieses Werkes haben in der Rezeption allerdings unterschiedliche Beachtung gefunden, da das sechste mehr christlich-philosophisch ausgerichtete Buch sich in Stil und Inhalt von den anderen fünf eher technisch ausgerichteten Büchern deutlich unterscheidet. Dies hat in der Forschung zu unterschiedlichen Spekulationen über die literarische und inhaltliche Einheitlichkeit von De musica geführt, zumal sich eine Überarbeitung des sechsten Buches tatsächlich nachweisen lässt. Es hat auch dazu geführt, dass in Untersuchungen zu dieser Schrift oft nur vom sechsten Buch ausgegangen und von den ersten fünf Büchern abgesehen wurde. Auch der in der folgenden Darstellung akzentuierte – und bisher kaum beachtete – Aspekt wird hauptsächlich im sechsten Buch greifbar. Dennoch wird als Neuansatz versucht, diesen in die als einheitlich zu erweisende Gesamtkonzeption aller sechs Bücher einzubetten. Dieser Aspekt betrifft die ethische Dimension der Schrift. Sie, so die Grundthese, stellt vom ersten Buch an einen zentralen Strang des Werkes dar. ...
The title compound, [Li3(C4F9O)3(C3H6O)3], features an open Li/O cube with an Li ion missing at one corner. Three of the four bridging O atoms of the cube carry a fluorinated tert-butyl residue, whereas the fourth is part of an acetone molecule. Two of the Li atoms are further bonded to a non-bridging acetone molecule. Two of the lithium ion coordination geometries are very distorted LiO4 tetrahedra; the third could be described as a very distorted LiO3 T-shape with two distant F-atom neighbours. The Li[cdots, three dots, centered]Li contact distances for the three-coordinate Li+ ion [2.608 (14) and 2.631 (12) Å] are much shorter that the contact distance [2.940 (13) Å] between the tetrahedrally coordinated species.
Uwe Timm and Robert Schiff have both written an autobiographical text dealing with the premature death of an elder brother who was a combattant in the Waffen-SS in their childhood. Despite the frappantly similar biographical constellation, there are differences in narrative technique and thematical focus that stem from their respective sociocultural context. The analysis shows that Timm is in many ways a representative author of the German ‘68 generation that critically reevaluates the attitude of their parents during the national socialist period and points to omissions and falsifications in the oral family history, while the narration of Schiff, an emigrated author born in the pre-war milieu of the German minority of Southwest Romania, is mainly a reconstruction of the impact of big history on his childhood and thus also the effort to conserve the memory of a world that has passed away and to reconcile himself with the experience of loss.
Nachhaltigkeit – (k)eine Kunst? : Bäume pflanzen, Bienen züchten: ars longa als Gemeinschaftsprojekt
(2010)
Vita brevis, ars longa – kurz ist das Leben, lang währt die Kunst: Wenngleich der Arzt Hippokrates, dem man den Aphorismus zuschreibt, seinerzeit kaum an die Bildende Kunst gedacht haben dürfte, galt diese über Jahrhunderte hinweg als vornehmste Schöpferin und Verwalterin die Zeiten überdauernder Werte.
Dies ist ein Nachruf für Herr Dr. Gerhard Hecht, der am 2. Februar 2009 nach schwerer Krankheit im Alter von 74 Jahren verstorben ist. Herr Hecht war langjähriger Vorsitzender der Regionalgruppe des Arbeitskreises Heimische Orchideen (AKHO) des Bezirkes Halle, dem Vorläufer des Arbeitskreises Heimische Orchideen Sachsen-Anhalt e. V. (AHO). Ein bewegtes Leben voller Engagement ist damit viel zu früh zu Ende gegangen.
Drei neue Rubus-Arten (Haselblattbrombeeren) der Sektion werden beschrieben: Rubus tilioides W. JANSEN & H.E. WEBER mit Vorkommen vor allem in Thüringen, außerdem in Sachsen und Sachsen-Anhalt; R. anhaltianus H.E. WEBER (mittleres bis südwestliches Sachsen-Anhalt, angrenzendes Thüringen) und R. orbifrons H. E. WEBER (südwestliches Sachsen-Anhalt, ein Nachweis auch im angrenzenden Thüringen). Neu für Sachsen-Anhalt nachgewiesen wurde Rubus xiphophorus H. E. WEBER. Außerdem wurden weitere Fundorte für Rubus wahlbergii ARRH. bei Bergwitz und Helbra in Sachsen-Anhalt ermittelt. Die neuen Arten sind illustriert durch Fotos ihrer Holotypen und von lebenden Pflanzen im Gelände. Ihre Verbreitung wird durch Auflistung von Herbarbelegen und durch Rasterkarten mitgeteilt.

Der Kormoran (Phalacrocorax carbo) war in Sachsen-Anhalt nicht immer ein regelmäßiger Brutvogel. So gab es von 1900 bis 1986 nur sporadische Ansiedlungen im Lande. Im Jahre 1987 entstand an der Saalemündung im Naturschutzgebiet Steckby-Lödderitzer Forst eine beständige Kolonie mit neun Brutpaaren (Dornbusch 2002). Erst fünf Jahre später, im Jahre 1992, wurde eine weitere Kolonie gegründet. Ein stärkerer Bestandszuwachs, verbunden mit weiteren Koloniegründungen, begann dann im Jahre 1994 und erreichte mit 1.096 Brutpaaren im Jahre 2009 seinen bisherigen Höhepunkt in Sachsen-Anhalt. Ein Jahr zuvor erlangte der Brutbestand mit 810 Brutpaaren einen ähnlichen Wert wie im Jahr 2006 (Dornbusch 2002, Fischer & Dornbusch 2009). Verschiedene Koloniestandorte sind inzwischen wieder aufgegeben worden. Offenbar tolerieren die Vögel Störungen in den Kolonien sowie die Prädation insbesondere durch Mink (Mustela vison), Waschbär (Procyon lotor) und Seeadler (Haliaeetus albicilla) nicht. Mit der deutschland- und europaweiten Zunahme des Brutbestandes (Keller et al. 2003) nahm auch der Durchzugs- und Überwinterungsbestand in Sachsen-Anhalt zu. Dieser wurde jedoch nicht regelmäßig erfasst. Eine Mittwinter-Synchronzählung an Schlafplätzen im Januar 2003 ergab einen Winterbestand von 1.570 Kormoranen. Die Zählung erfolgte jedoch während einer extremen Kälteperiode und spiegelt aufgrund der vorher einsetzenden Winterflucht vermutlich nicht den realen Winterbestand der Art wider (Dornbusch & Fischer 2004). Datenerhebungen im Rahmen der internationalen Wasservogelzählung (z. B. Schulze 2008) lassen für die Jahre 2003 bis 2008 auf einen Winterbestand von ca. 3.000 Kormoranen schließen. In den Zugzeiten von Oktober bis November können kurzzeitig auch bis zu 5.000 Kormorane auftreten.
Wissenschaftler vom Exzellenzcluster »Makromolekulare Komplexe« der Goethe-Universität haben in Zusammenarbeit mit der Universität Freiburg die Architektur des größten Proteinkomplexes der zellulären Atmungskette aufgeklärt. Sie entdeckten einen bisher unbekannten Mechanismus der nergieumwandlung in diesem molekularen Komplex. Der Mechanismus ist notwendig, damit die Zelle die in der Nahrung gespeicherte Energie nutzen kann.
Background: Due to the use of organophosphates (OP) as pesticides and the availability of OP-type nerve agents, an effective medical treatment for OP poisonings is still a challenging problem. The acute toxicity of an OP poisoning is mainly due to the inhibition of acetylcholinesterase (AChE) in the peripheral and central nervous systems (CNS). This results in an increase in the synaptic concentration of the neurotransmitter acetylcholine, overstimulation of cholinergic receptors and disorder of numerous body functions up to death. The standard treatment of OP poisoning includes a combination of a muscarinic antagonist and an AChE reactivator (oxime). However, these oximes can not cross the blood-brain barrier (BBB) sufficiently. Therefore, new strategies are needed to transport oximes over the BBB. Methodology/Principal Findings: In this study, we combined different oximes (obidoxime dichloride and two different HI 6 salts, HI 6 dichloride monohydrate and HI 6 dimethanesulfonate) with human serum albumin nanoparticles and could show an oxime transport over an in vitro BBB model. In general, the nanoparticulate transported oximes achieved a better reactivation of OP-inhibited AChE than free oximes. Conclusions/Significance: With these nanoparticles, for the first time, a tool exists that could enable a transport of oximes over the BBB. This is very important for survival after severe OP intoxication. Therefore, these nanoparticulate formulations are promising formulations for the treatment of the peripheral and the CNS after OP poisoning.
Native vegetation of the NSW south coast, escarpment and southeast tablelands was classified into 191 floristic assemblages at a level of detail appropriate for the discrimination of Threatened Ecological Communities and other vegetation units referred to in government legislation. Assemblages were derived by a numerical analysis of 10832 field sample quadrats including 8523 compiled from 63 previous vegetation surveys. Past bias in the distribution of field data towards land under public tenure was corrected by extensive surveys carried out on private land. The classification revises and integrates the units described in recent vegetation studies of Eden, Cumberland Plain and Sydney-south coast into a single, consistent classification. Relationships between floristic assemblages and climate, terrain, substrate and vegetation structure were used to map the distribution of communities prior to clearing at 1:100 000 scale. The extent of clearing was mapped using interpretations of remote imagery (1991–2001) from previous work, standardised and merged into a single coverage and supplemented with additional work. Profiles for each assemblage, which we term ‘communities’ or ‘map units’, describe their species composition, vegetation structure, environmental habitat, the extent of clearing and conservation status. Lists of diagnostic species were defined using a statistical fidelity measure and a procedure for using these for community identification is described. Approximately 66% of the study area retains a cover of native vegetation, primarily in areas with low fertility soils and dissected topography. Communities subject to over-clearing (>70%) are concentrated in a few large areas characterised by clay/loam soils and flat to undulating terrain. These include the Sydney metropolis, Wingecarribee Plateau, Illawarra Plain, Shoalhaven floodplain, Araluen Valley and Bega Valley, and various smaller river valleys. Forty-one percent of remaining native vegetation is protected within conservation reserves while 31% occurs on private land, 20% in State Forests and 8% on other Crown lands. Forty-five Threatened Ecological Communities (TECs) were recorded in the study area. The majority of TECs are represented by a single map unit, although in some cases a TEC is included within a broader map unit. Twelve TECs are represented by combinations of two or more map units.
Navigare necesse est : de Magalhães a Vespúcio ; três navegadores reinventados por Stefan Zweig
(2010)
"Navigare necesse est" [...] Ao longo dos tempos, esta expressão de ousadia conservou-se no discurso literário da cultura ocidental. No século XX, serviram-se dela, por exemplo, dois autores indelevelmente inscritos na memória cultural da língua portuguesa: o poeta Fernando Pessoa, como vimos, e ainda o cantautor Caetano Veloso. […] Nesta linha de apropriação se situa também o escritor austríaco Stefan Zweig quando, em 1937, intitula “Navigare necesse est” o capítulo introdutório da biografia “Magellan. Der Mann und seine Tat”. Ao contrário dos autores de língua portuguesa acima mencionados, Zweig adopta apenas o primeiro segmento do axioma, pois no fenómeno de intertextualidade [...]. Zweig aproveita a expressão no enquadramento semântico original – as navegações –, para a aplicar à linhagem de bravos homens do mar e de eruditos cosmógrafos que tornaram possível a era dos Descobrimentos. Nesse capítulo inicial da narração biográfica, a voz autoral traça uma panorâmica da primeira fase das Descobertas, mostrando como o móbil económico, que desencadeou todo o processo, acabou por trazer à Humanidade ganhos de outra natureza. Assim, os Descobrimentos não terão permitido apenas chegar à Índia e às tão desejadas especiarias: a demanda corajosa e continuada ter-se-á justificado principalmente por desafiar os mitos do oceano, afastar os medos do mar e alargar a nossa dimensão do mundo.
Records of Nesticodes rufipes (Lucas, 1846) from Saxony, Germany are presented. The three females of Nesticodes rufipes were found associated with the zoo trade in the cities of Chemnitz and Plauen in cricket boxes. Female genitalia are illustrated.
Heparine sind die am häufigsten verwendeten Medikamente zur Kontrolle der Blutgerinnung. In hoher Dosierung werden sie in der Herzchirurgie eingesetzt, um Blutgerinnseln während einer Operation vorzubeugen. Ein am Institut für Biophysik entwickeltes Messverfahren erlaubt eine direkte und schnelle Messung des Heparinspiegels während des Eingriffs.
Das Scheitern der traditionellen, disziplinär verengten Umweltforschung bei der Lösung sehr komplexer Umweltprobleme förderte die Herausbildung eines neuen Forschungstyps: der Nachhaltigkeitsforschung, einer inter- oder transdisziplinären Wissenschaft, die im Spannungsfeld von Gesellschaft(-swissenschaften)und Natur(-wissenschaften) agiert. Bei ihrer Entstehung spielten in Deutschland kleine, gemeinnützige Forschungsinstitute eine zentrale Rolle.
Background: Studies on the development of the nervous system and the musculature of invertebrates have become more sophisticated and numerous within the last decade and have proven to provide new insights into the evolutionary history of organisms. In order to provide new morphogenetic data on opisthobranch gastropods we investigated the neuromuscular development in the nudibranch Aeolidiella stephanieae Valdez, 2005 using immunocytochemistry as well as F-actin labelling in conjunction with confocal laser scanning microscopy (cLSM). Results: The ontogenetic development of Aeolidiella stephanieae can be subdivided into 8 stages, each recognisable by characteristic morphological and behavioural features as well as specific characters of the nervous system and the muscular system, respectively. The larval nervous system of A. stephanieae includes an apical organ, developing central ganglia, and peripheral neurons associated with the velum, foot and posterior, visceral part of the larva. The first serotonergic and FMRFamidergic neural structures appear in the apical organ that exhibits an array of three sensory, flask-shaped and two non-sensory, round neurons, which altogether disappear prior to metamorphosis. The postmetamorphic central nervous system (CNS) becomes concentrated, and the rhinophoral ganglia develop together with the anlage of the future rhinophores whereas oral tentacle ganglia are not found. The myogenesis in A. stephanieae begins with the larval retractor muscle followed by the accessory larval retractor muscle, the velar or prototroch muscles and the pedal retractors that all together degenerate during metamorphosis, and the adult muscle complex forms de novo. Conclusions: Aeolidiella stephanieae comprises features of the larval and postmetamorphic nervous as well as muscular system that represent the ground plan of the Mollusca or even the Trochozoa (e. g. presence of the prototrochal or velar muscle ring). On the one hand, A. stephanieae shows some features shared by all nudibranchs like the postmetamorphic condensation of the CNS, the possession of rhinophoral ganglia and the lack of oral tentacle ganglia as well as the de novo formation of the adult muscle complex. On the other hand, the structure and arrangement of the serotonergic apical organ is similar to other caenogastropod and opisthobranch gastropods supporting their sister group relationship.
Butterflies of the superfamilies Hesperioidea and Papilionoidea collected in the Cape Verde Islands and deposited in the Instituto de Investigação Científica Tropical, Lisbon, Portugal, were studied. Some novelties are reported at the insular level and one Palearctic species of Nymphalidae is reported for the first time in the islands. The identification of the only species of Colias (Pieridae) present in the Cape Verde Islands and its biogeographical affinities are discussed.
This fourth paper in the NSW Vegetation Classification and Assessment series covers the Brigalow Belt South-/1(BBS) and Nandewar (NAN) Bioregions and the western half of the New England Bioregion (NET), an area of 9.3 million hectares being 11.6% of NSW. It completes the NSWVCA coverage for the Border Rivers-Gwydir and Namoi CMA areas and records plant communities in the Central West and Hunter–Central Rivers CMA areas. In total, 585 plant communities are now classified in the NSWVCA covering 11.5 of the 18 Bioregions in NSW (78% of the State). Of these 226 communities are in the NSW Western Plains and 416 are in the NSW Western Slopes. 315 plant communities are classified in the BBS, NAN and west-NET Bioregions including 267 new descriptions since Version 2 was published in 2008. Descriptions of the 315 communities are provided in a 919 page report on the DVD accompanying this paper along with updated reports on other inland NSW bioregions and nine Catchment Management Authority areas fully or partly classified in the NSWVCA to date. A read-only version of Version 3 of the NSWVCA database is on the DVD for use on personal computers. A feature of the BBS and NAN Bioregions is the array of ironbark and bloodwood Eucalyptusdominated shrubby woodlands on sandstone and acid volcanic substrates extending from Dubbo to Queensland. This includes iconic natural areas such as Warrumbungle and Mount Kaputar National Parks and the 500,000 ha Pilliga Scrub forests. Large expanses of basalt-derived soils support grassy box woodland and native grasslands including those on the Liverpool Plains; near Moree; and around Inverell, most of which are cleared and threatened. Wetlands occur on sodic soils near Yetman and in large clay gilgais in the Pilliga region. Sedgelands are rare but occupy impeded creeks. Aeolian lunettes occur at Narran Lake and near Gilgandra. Areas of deep sand contain Allocasuarina, eucalypt mallee and Melaleuca uncinata heath. Tall grassy or ferny open forests occur on mountain ranges above 1000m elevation in the New England Bioregion and on the Liverpool Range while grassy box woodlands occupy lower elevations with lower rainfall and higher temperatures. The vegetation classification and assessment is based on over 100 published and unpublished vegetation surveys and map unit descriptions, expert advice, extra plot sampling and data analysis and over 25 000 km of road traverse with field checking at 805 sites. Key sources of data included floristic analyses produced in western regional forest assessments in the BBS and NAN Bioregions, floristic analyses in over 60 surveys of conservation reserves and analysis of plot data in the western NET Bioregion and covering parts of the Namoi and Border Rivers- Gwydir CMA areas. Approximately 60% of the woody native vegetation in the study area has been cleared resulting in large areas of “derived” native grasslands. As of June 2010, 7% of the area was in 136 protected areas and 127 of the 315 plant communities were assessed to be adequately protected in reserves. Using the NSWVCA database threat criteria, 15 plant communities were assessed as being Critically Endangered, 59 Endangered, 60 Vulnerable, 99 Near Threatened and 82 Least Concern. 61 of these communities are assessed as part of NSW or Commonwealth-listed Threatened Ecological Communities. Current threats include expanding dryland and irrigated cropping on alluvial plains, floodplains and gently undulating topography at lower elevations; over-grazing of steep hills; altered water tables and flooding regimes; localized mining; and the spread of exotic species, notably Coolatai Grass (Hyparrhenia hirta).
New vegetation data of dry grasslands in the Western Carpathians and the northern Pannonian Basin
(2010)
The paper presents new vegetation data from dry grassland sites in the biogeographical regions of the Western Carpathians and the northern Pannonian Basin, mainly belonging to the alliances Bromo pannonici-Festucion pallentis and Festucion valesiacae (Festuco-Brometea). The 124 phytosociological relevés were sampled between 2005 and 2009 in Slovakia, the SE Czech Republic, NE Austria, and N Hungary. They are classified into 16 associations and four transitional vegetation types. The paper also brings new information on the distribution of grassland associations in the study area. A new locality of the rare association Teucrio botryos-Andropogonetum ischaemi was confirmed. During our recent investigation of historical sites of the Alopecuro pratensis-Festucetum pseudovinae (Cynosurion cristati, Molinio-Arrhenatheretea) in the Slaná river floodplain, only one occurrence could be confirmed. Geographical principles in distribution of dry grassland associations and classification of the Stipa pulcherrima-dominated stands are also discussed.
Die Literaturgeschichte quillt über on Werken über den Krieg, aus dem Krieg, mit dem Krieg, gegen den Krieg. Ein Heldenepos schien jahrhundertelang nicht anders denkbar denn als Erzählung von Kämpfern, Kriegern, Eroberern. [...] Im 20. Jahrhundert entstehen, oft im Widerspruch zu solcher Privatisierung, neue Formen, mit dem Krieg, der dieses Jahrhundert noch entsetzlicher traf als vorhergegangene, literarisch fertig zu werden: Dokumentation, Erlebnisbericht, Lautgedicht, Medienkritik, aber auch Schriften, in denen Kriegskameraderie als Alternative zur bürgerlichen Lebenswelt erscheint. Die Jugoslawienkriege der neunziger Jahre haben Europa auch außerhalb der unmittelbar betroffenen Gebiete erschüttert. Innerhalb der deutschsprachigen Literatur haben ich in den letzten Jahren nicht wenige Autoren mit zeitgenössischen Kriegen befaßt. Aus der Fülle von Texten greife ich drei nicht-fiktionale heraus; drei Reiseberichte, wenn auch höchst unterschiedlicher Natur, von Angehörigen verschiedener Generationen verfßt. Peter Handke ist ein Kriegskind, 1942 geboren; Juli Zeh, Jahrgang 1974, hat die Jugoslawienkriege als Jugendliche über die Medien mitbekommen, Peter Waterhouse, Jahrgang 1956, steht zwischen den beiden Generationen, sein Vater war sowohl im Zweiten Weltkrieg wie auch im Kalten Krieg in einer Weise aktiv, die für den Autor Beweggrund zu vielerlei Fragen ist.
Der Naturpark Drömling ist das größte Niedermoorgebiet in Mitteldeutschland. Die Wiedervernässung des Moorkörpers, der Schutz und die Pflege des extensiven Grünlandes und die Verbesserung des ökologischen Zustandes der Gewässer sind als Hauptziele im Pflege- und Entwicklungsplan festgeschrieben. In 11 Teilgebieten hat die Wiedervernässung bereits begonnen bzw. ist in Kürze geplant. Durch Umgestaltungsmaßnahmen wie Uferabflachung und Anlage von Flachwasserzonen sowie Einschränkung der Unterhaltungsmaßnahmen konnten die Lebensbedingungen für Flora und Fauna in den Gräben und Kanälen deutlich verbessert werden. Während die Gräben und Kanäle früher zur schnellen Entwässerung der Flächen im Frühjahr genutzt wurden, dienen sie heute auch dem Wasserrückhalt und der Bewässerung in Trockenzeiten. Eine Reihe von Flachgewässern vorwiegend für die amphibische und Avifauna wurden in den letzten Jahren neu geschaffen. Alle diese Maßnahmen fördern die Vielfalt der Lebensräume und damit den Naturschutzwert des Gebietes, so dass auch zahlreiche geschützte und gefährdete Arten auftreten. Es konnten 50 Arten von Makroinvertebraten und 20 Pflanzenarten der Roten Listen nachgewiesen werden; wesentlich mehr als in anderen Niedermoorgebieten Norddeutschlands. Ein zunehmendes Problem ist das Auftreten von Neozoen. Der Erhalt der Vielfältigkeit der Landschaft und der Gewässerformen erfordert jedoch einen gewissen Unterhaltungsaufwand.
NO DIRECTION HOME: Ein Titel, der bereits andeutet, dass es kein Zurück gibt. Entnommen ist der Titel einer Zeile des 1965 von Bob Dylan geschriebenen Songs Like a Rolling Stone, der im selben Jahr auf dem bis dahin sechsten Album Highway 61 Revisited erschienen ist. Er thematisiert den Abstieg von der upper class zum underdog und die damit einhergehende Ignoranz und Verachtung seitens der Gesellschaft. Dieser Song wurde 2004 vom Rolling Stone Magazine zum besten Rocksong aller Zeiten gewählt. Doch was hat dieser Song mit dem Werk Bob Dylans zu tun, zumal die einführenden Worte Dylans den konträren Standpunkt vertreten und suggerieren, dass der folgende Film die Reise nach Hause dokumentieren wird?
Gibt es irgendeine Berechtigung, die ausgetretenen Pfade der Interpretation erneut zu beschreiten und sich den Liedern aus Goethes Roman Wilhelm Meisters Lehrjahre noch einmal und immer wieder zu nähern? Uferlos erscheint die Liste der Forschungsarbeiten, die sich mit diesen Liedern und/oder der Figur Mignon beschäftigen; gerade Mignon hat in der "Deutungstradition" von Goethes Bildungsroman ihren unbestrittenen Platz. Warum also noch einmal? Ein gewisses Anrecht auf ein wiederholtes und neues Lesen der bekannten Stellen genehmigt Goethes Roman selbst, sind es doch gerade Mignons Lieder, die sich zur mehrfachen und dauerhaften "Wiederholung" bekennen, ja die eine dauernde Wiederholung sogar einfordern. Man hat schon von einem "Wiederholungszwang" gesprochen, der durch diese Lieder vorangetrieben werde. Mignons Lieder arbeiten nicht nur häufig mit der Wiederholungsfigur des Refrains; auch ihr Hörer Wilhelm kann nicht umhin, sich diese Lieder mehrfach "wiederholen" zu lassen (234). Könnte es also sein, dass in dieser Wiederholungsmanie ein Hinweis darauf steckt, wie diese Lieder zu verstehen sind?
Der Tagungsvortrag von Herrn Pilch, und noch mehr dessen Ausarbeitung in diesem Band, weist im Verhältnis zu seinem Buch eine klarere Ausrichtung auf die rechtshistorische Problematik auf. Die doppelte Fragestellung gegenüber dem modernen Normbegriff und der mittelalterlichen Rechtsgewohnheit wurde zu Gunsten einer Konzentration auf die letztere reduziert. So steht die Thematik jetzt viel deutlicher vor uns. Ich kann mich deshalb darauf beschränken, einige grundsätzliche Probleme noch einmal aus meiner Sicht anzusprechen und schärfer zu beleuchten. ...
A new, two-channel instrument for simultaneous NO3 and N2O5 monitoring was used to make the first comprehensive set of nocturnal NOx measurements (NO, NO2, NO3 and N2O5) at the Taunus Observatory, a rural mountain site (Kleiner Feldberg) in South-western Germany. In May 2008, NO3 and N2O5 mixing ratios were well above the instrumental detection limit (a few ppt) on all nights of the campaign and were characterised by large variability resulting from inhomogeneously distributed sinks. The concentrations of NO3, N2O5 and NO2 were consistent with the equilibrium constant, K2, defining the rates of formation and thermal dissociation of N2O5. A steady-state lifetime analysis showed that nocturnal NOx losses were generally dominated by reaction of NO3 with volatile organic compounds in this forested region, with N2O5 uptake to aerosols of secondary importance. Analysis of a limited dataset obtained at high relative humidity indicated that the loss of N2O5 by reaction with water vapour is less efficient (> factor 3) than derived using laboratory kinetic data. The fraction of NOx present as NO3 and N2O5 reached ≈20% on some nights, with night-time losses of NOx competing with daytime losses.

Background: Many disabling human retinal disorders involve the central retina, particularly the macula. However, the commonly used rodent models in research, mouse and rat, do not possess a macula. The purpose of this study was to identify small laboratory rodents with a significant central region as potential new models for macular research.
Methodology/Principal Findings: Gerbillus perpallidus, Meriones unguiculatus and Phodopus campbelli, laboratory rodents less commonly used in retinal research, were subjected to confocal scanning laser ophthalmoscopy (cSLO), fluorescein and indocyanine green angiography, and spectral-domain optical coherence tomography (SD-OCT) using standard equipment (Heidelberg Engineering HRA1 and Spectralis™) adapted to small rodent eyes. The existence of a visual streak-like pattern was assessed on the basis of vascular topography, retinal thickness, and the topography of retinal ganglion cells and cone photoreceptors. All three species examined showed evidence of a significant horizontal streak-like specialization. cSLO angiography and retinal wholemounts revealed that superficial retinal blood vessels typically ramify and narrow into a sparse capillary net at the border of the respective area located dorsal to the optic nerve. Similar to the macular region, there was an absence of larger blood vessels in the streak region. Furthermore, the thickness of the photoreceptor layer and the population density of neurons in the ganglion cell layer were markedly increased in the visual streak region.
Conclusions/Significance: The retinal specializations of Gerbillus perpallidus, Meriones unguiculatus and Phodopus campbelli resemble features of the primate macula. Hence, the rodents reported here may serve to study aspects of macular development and diseases like age-related macular degeneration and diabetic macular edema, and the preclinical assessment of therapeutic strategies.
O estilo em Alfred Döblin
(2010)
O objetivo do presente artigo é apresentar alguns aspectos teóricos postulados pelo escritor alemão Alfred Döblin em seus ensaios ao desenvolver sua própria concepção da obra épica na "era da técnica" à luz de questões estilísticas, propondo conceitos como "estilo cinematográfico", "despersonalização", "fantasia factual" e "fantasia cinética". Para uma delimitação conceitual em relação à noção de "estilo", serão tomadas por base as considerações de Antoine Compagnon, postuladas na obra "O demônio da teoria" (1999), bem como as reflexões de Walter Benjamin, presents na resenha "A crise do romance" (1930) e no ensaio "O narrador" (1936).
U radu se predstavljaju rezultati terenskog istraživanja o nazivima za uskršnju pletenicu, provedenog na gotovo dvjesto punktova duž hrvatske obale te u unutrašnjosti Istre i nadopunjenog podatcima iz objavljene literature. Istraživanjem su, radi usporedbe, zahvaćena i neka naselja u Gorskom kotaru te u unutrašnjosti Dalmacije. Analiza prikupljenog korpusa ukazuje na snažnu prisutnost slike sadržaja ‘ptica’ u našim jadranskim nazivima za uskršnju pletenicu, bilo da je riječ o nazivima slavenskog ili romanskog (dalmatskog, istroromanskog ili mletačkog) podrijetla. Na temelju tih zapažanja ponovno se razmatraju neka dosad predložena etimološka rješenja (Skok, Vinja) te donose novi etimološki prijedlozi.
U ovome su radu obradena 232 obiteljska nadimka u Puciscima na otoku Bracu. Obiteljski su nadimci, kao dodatan vid identifikacije koji se razvio još u pretprezimenskome razdoblju, a kasnije je sve zastupljeniji zbog brojnosti nositelja pojedinih prezimena, svojevrsni specifikum hrvatskih otoka koji dosad nije dostatno proucen. U Puciscima se obiteljski nadimci bilježe od konca 16. st. te se na temelju njihove motivacije može djelomicno rekonstruirati fond osobnih imena (odnos hrvatskih narodnih imena te hrvatskih i novijih romanskih prilagodenica kršcanskih imena), vanjština (posebice tjelesne mane), karakterne crte (uglavnom nekonvencionalne) te podrijetlo i svakodnevni život Puciscana. Fond je obiteljskih nadimaka znatno otvoreniji inojezicnim sustavima (poglavito romanskim) te je odraz svojevrsne tisucljetne hrvatsko-romanske simbioze na istocnoj obali Jadranskoga mora.
This paper investigates the potential impact of secondary information on rainfall mapping applying Ordinary Kriging. Secondary information tested is a natural area indicator, which is a combination of topographic features and weather conditions. Cross validation shows that secondary information only marginally improves the final mapping, indicating that a one-day accumulation time is possibly too short.
On demand treatment and home therapy of hereditary angioedema in Germany - the Frankfurt experience
(2010)
Background: Manifestation of acute edema in hereditary angioedema (HAE) is characterized by interindividual and intraindividual variability in symptom expression over time. Flexible therapy options are needed. Methods: We describe and report on the outcomes of the highly individualized approach to HAE therapy practiced at our HAE center in Frankfurt (Germany). Results: The HAE center at the Frankfurt University Hospital currently treats 450 adults with HAE or AAE and 107 pediatric HAE patients with highly individualized therapeutic approaches. 73.9% of the adult patients treat HAE attacks by on-demand therapy with pasteurized pd C1-INH concentrate, 9.8% use additional prophylaxis with attenuated androgens, 1% of the total patient population in Frankfurt has been treated with Icatibant up to now. In addition adult and selected pediatric patients with a high frequency of severe attacks are instructed to apply individual replacement therapy (IRT) with pasteurized pd C1-INH concentrate. Improvement on Quality of Life items was shown for these patients compared to previous long-term danazol prophylaxis. Home treatment of HAE patients was developed in the Frankfurt HAE center in line with experiences in hemophilia therapy and has so far been implemented over a period of 28 years. At present 248 (55%) of the adult patients and 26 (24%) of the pediatric patients are practicing home treatment either as on demand or IRT treatment. Conclusions: In conclusion, the individualized home therapies provided by our HAE center, aim to limit the disruption to normal daily activities that occurs for many HAE patients. Furthermore, we seek to optimize the economic burden of the disease while offering a maximum quality of life to our patients.
The arid and semi-arid southwest of New South Wales has received disproportionately less attention from botanists than other similar-sized geographic regions of the state. Recent work has extended our knowledge of three extremely rare plant taxa from this part of the state. Zygophyllum compressum (Zygophyllaceae) and Elachanthus glaber (Asteraceae) are restricted to gypseous rises within active saline groundwater discharge complexes with limited distribution in southwest New South Wales and occur within the plant community “Gypseous shrubland on rises and semi-arid plains” (ID253) which is listed as threatened (vulnerable) within the state. Eremophila crassifolia (Myoporaceae) is restricted to a few plants on a roadside and adjacent mallee vegetation approximately 35 km east of Wentworth. Based on IUCN criteria it is suggested that Eremophila crassifolia is critically endangered and Zygophyllum compressum and Elachanthus glaber endangered in New South Wales and all should be listed under the NSW Threatened Species Conservation Act 1995.
Background: Environmental noise is ubiquitous in population growth processes, with a well acknowledged potential to affect populations regardless of their sizes. It therefore deserves consideration in population dynamics modelling. The usual approach to incorporating noise into population dynamical models is to make some model parameter(s) (typically the growth rate, the carrying capacity, or both) stochastic and responsive to environment fluctuations. It is however still unclear whether including noise in one or/and another parameter makes a difference to the model performance. Here we investigated this issue with a focus on model fit and predictive accuracy. To do this, we developed three population dynamical models of the Ricker type with the noise included in the growth rate (Model 1), in the carrying capacity (Model 2), and in both (Model 3). We generated several population time series under each model, and used a Bayesian approach to fit the three models to the simulated data. We then compared the model performances in fitting to the data and in forecasting future observations. Results: When the mean intrinsic growth rate, r, in the data was low, the three models had roughly comparable performances, irrespective of the true model and the level of noise. As r increased, Models 1 performed best on data generated from it, and Model 3 tended to perform best on data generated from either Models 2 or Model 3. Model 2 was uniformly outcompeted by the other two models, regardless of the true model and the level of noise. The correlation between the deviance information criterion (DIC) and the mean square error (MSE) used respectively as measure of fit and predictive accuracy was broadly positive. Conclusion: Our results suggested that the way environmental noise is incorporated into a population dynamical model may profoundly affect its performance. Overall, we found that including noise in one or/and another parameter does not matter as long as the mean intrinsic growth rate, r, is low. As r increased, however, the three models performed differently. Models 1 and 3 broadly outperformed Model 2, the first having the advantage of being simple and more computationally tractable. A comforting result emerging from our analysis is the broad positive correlation between MSEs and DICs, suggesting that the latter may also be informative about the predictive performance of a model.
In this paper we present evidence that the observed increase in tropical upwelling after the year 2000 may be attributed to a change in the Brewer-Dobson circulation pattern. For this purpose, we use the concept of transit times derived from residual circulation trajectories and different in-situ measurements of ozone and nitrous dioxide. Observations from the Canadian midlatitude ozone profile record, probability density functions of in-situ N2O observations and a shift of the N2O-O3 correlation slopes, taken together, indicate that the increased upwelling in the tropics after the year 2000 appears to have triggered an intensification of tracer transport from the tropics into the extratropics in the lower stratosphere below about 500 K. This finding is corroborated by the fact that transit times along the shallow branch of the residual circulation into the LMS have decreased for the same time period (1993–2003). On a longer time scale (1979–2009), the transit time of the shallow residual circulation branch show a steady decrease of about −1 month/decade over the last 30 years, while the transit times of the deep branch remain unchanged. This highlights the fact that a change in the upwelling across the tropical tropopause is not a direct indicator for changes of the whole Brewer-Dobson circulation.
ONE NIGHT IN PARIS entstand am 9. und 10. Oktober 2001 im Palais Omnisport, Paris. Zwar wird nur der 10. Oktober als Aufnahmedatum angegeben, der Song It Doesn’t Matter Two, der im Film zu sehen ist, wurde jedoch nur am 9. Oktober gespielt und zeigt somit, dass Material von beiden Auftritten verwendet wurde. An den fast zweistündigen Konzertmitschnitt schließt sich umfangreiches Zusatzmaterial an, unter anderem Interviews und Hintergrundinformationen über die Vorbereitung und Umsetzung der Tour.
'One Plus One' entstand während einer über mehrere Monate verteilten Aufnahmestudio-Session der Rolling Stones im Juni und August 1968 in den Olympic Studios in London. Die Band kam ohne Vorbereitung ins Studio und entwickelte den Song 'Sympathy for the Devil' improvisatorisch im Laufe der Sessions. Die Arbeit am Stück begann mit einem Liedtext von Sänger Mick Jagger unter dem Arbeitstitel 'The Devil Is My Name'. Jagger hatte diesen Text unter dem Eindruck des Romans 'Der Meister und Margarita' des russischen Schriftstellers Michail Bulgakov verfasst - ein Buch, das er von seiner Partnerin Marianne Faithfull erhalten hatte. In Bulgakovs Roman stattet der Teufel dem Moskau der 1930er Jahre einen Besuch ab, in dessen Verlauf er viele Menschen tötet oder in den Wahnsinn treibt. Der Film zeigt die Arbeit an dem Song, der auf einem treibenden Samba-Rhythmus aufruht, in den verschiedenen Entwicklungsstufen, in immer neuen Ansätzen, sich dem späteren Format annähernd. Der Song wurde 1968 auf dem Studioalbum 'Beggars Banquet' als erstes von zehn Liedern veröffentlicht.
Only the strong survive
(2010)
Der zum Zeitpunkt des Films 72jährige Don A. Pennebaker und seine Ehefrau Chris Hegedus gelten als Pioniere des amerikanischen Direct Cinema. Mit Filmen wie 'Don't Look Back' (1967) über Bob Dylan oder 'Monterey Pop' (1968) über das gleichnamige Musikfestival an der Westküste der USA haben die beiden sich in der Geschichte des Dokumentarfilms einen Namen gemacht, der weit über die Fans der jeweiligen Musik hinausgeht. Direct Cinema wurde von den beiden als das unmittelbare Abfilmen der Realität verstanden, die sich vor ihrer Kamera befand. Ein Eingreifen in das Geschehen wurde ebenso strikt abgelehnt wie jeglicher Kommentar. Pennebaker schuf damit einerseits Konzertfilme, die auch die Stimmung, das Publikum, das gesamte Setting mit einfingen (wie eben in 'Monterey Pop'). Andererseits gelang ihm etwa in 'Don't Look Back' ein Porträt des jungen Bob Dylan, das über reine Konzertaufnahmen weit hinausgeht und in der Konzentration auf einen Protagonisten auch imstande ist, einiges über das Verhältnis zwischen Fans und Star, deren Projektionen und den Umgang von Akteuren der Rockmusik mit schnell erworbenem Starstatus zu erzählen.
V lingvistickém výzkumu byla malá pozornost věnována onomatopoickým výrazŧm ĉasto uţívaným zvláště v komiksech a v dětské literatuře jako nástroj k vyjádření emocí. Ĉlánek, jehoţ cílem je vyplnit mezeru ve výzkumu, nejprve podává přehled o vztazích mezi onomatopoi a emocemi. Autor zdŧrazňuje, ţe konkrétní realizace onomatopoických slov je v kaţdém jazyce jiná a závisí na jazykových konvencích. Následně jsou srovnána německá a ĉeská onomatopoická slovesa s emoĉními konotacemi. Srovnání ukazuje širokou škálu rozdílŧ, které se týkají nejen formálních aspektŧ, ale také významu těchto sloves. Závěrem vyplývá, ţe emoce jsou vázány na jazykový kontext, a proto nemohou být přesně přeloţeny.
Oomyceten – schön, nützlich und gefährlich : sie sind überall zu finden und dennoch kaum bekannt
(2010)
Auf Pflanzen sind sie klein, unscheinbar und leicht verwechselbar. Den Betrachter betören sie beim Blick ins Mikroskop durch wunderschön geformte Sporenträger. Doch Oomyceten, die lange Zeit mit Pilzen verwechselt wurden, können als Pflanzenschädlinge beträchtlichen landwirtschaftlichen Schaden anrichten. Die einzelnen Arten zu unterscheiden und ihre Wirtspflanzen zu kennen, ist eine Voraussetzung dafür, ihre Verbreitung zu kontrollieren. Denn auch in Europa könnten exotische Arten aufgrund der Erderwärmung heimisch werden – mit erwünschten und unerwünschten Folgen.
Family members provide most of the patient care and administer most of the treatments to patients with Alzheimer’s disease (AD). Family caregivers have an important impact on clinical outcomes, such as quality of life (QoL). As a consequence of this service, family caregivers suffer high rates of psychological and physical illness as well as social and financial burdens. Hence, it is important to involve family caregivers in multimodal treatment settings and provide interventions that are both suitable and specifically tailored to their needs. In recent years, several clinical guidelines have been presented worldwide for evidence-based treatment of AD and other forms of dementia. Most of these guidelines have considered family advice as integral to the optimal clinical management of AD. This article reviews current and internationally relevant guidelines with emphasis on recommendations concerning family advice.
This essay examines the differing contexts and modes of encounter with Islamic culture in the travel writing of two contrasting women, the Prussian Countess Ida Hahn-Hahn and the Austrian Maria Schuber: both travelled to and wrote from the Middle East in the 1830s and 1840s and published their letters as collections. The encounters both women had with Islam were conditioned, at least in part, by their respective stance on religion, issues of gender and social class, and by the obligations of patronage and the expectations of distinct readerships. Whilst both women can be seen to write about Islam as a religion and culture defined by its difference to Christianity, both can also be seen in differing ways and to differing extents to represent Islam and Muslims as simultaneously belonging to a universal and inclusive notion of humanity and human religion. Thus, without embracing high philosophical discourse of Kant or Hegel, both women can be seen to demonstrate cosmopolitan impulses towards Islam, although these jostle for ascendancy with a more Eurocentric, Christian and indeed völkisch vision of the relationship between cultures.
It could be said that learner’s dictionaries are the most reliable expression of lexicography in terms of providing the necessary tools to help the learning process of a foreign language. This paper analyses three English learner’s dictionaries in order to establish its stylistic patterns as well as to compare them with four German learner’s dictionaries. Undoubtly, the lexicography of English learner’s dictionaries is a model. However, we argue that this model can not be transfered to German lexicography since each language has its own particularities which demand specific solutions.
Dieses Buch (mit einem Vorwort des leider verstorbenen Jean-Pierre Maelfait) wurde von einem Kollektiv von 10 Autoren verfasst und besteht aus zwei Teilen. Der erste Teil, welchem eine Liste aller im Buch vorgestellten Gattungen und Arten vorangestellt ist, enthält eine kurze allgemeine Einleitung in die Biologie der Spinnen, mit Beschreibungen von Anatomie, Physiologie, Reproduktion und des Netzbaus (S. 1-63), sowie eine Einführung in das Sammeln von Spinnen (S. 64-69). Zusätzlich sind dort noch zwei Schlüssel zu Spinnenfamilien, einer basierend auf morphologischen Merkmalen und ein zweiter basierend auf den Netztypen, vorhanden.
Palystes kreutzmanni sp. n. is described from habitats close to Kleinmond, in the Western Cape Province, South Africa. Spiders of this new species live in the typical fynbos vegetation of the Western Cape region. They build retreats between apical leaves of Leucadendron bushes. The systematic position of Palystes kreutzmanni sp. n. is discussed. Male and female show characters of different species groups, especially the female copulatory organ seems to be unique within the genus Palystes L. Koch, 1875.
Pancreatic resections for advanced M1-pancreatic carcinoma : the value of synchronous metastasectomy
(2010)
Background: For M1 pancreatic adenocarcinomas pancreatic resection is usually not indicated. However, in highly selected patients synchronous metastasectomy may be appropriate together with pancreatic resection when operative morbidity is low.
Materials and Methods: From January 1, 2004 to December, 2007 a total of 20 patients with pancreatic malignancies were retrospectively evaluated who underwent pancreatic surgery with synchronous resection of hepatic, adjacent organ, or peritoneal metastases for proven UICC stage IV periampullary cancer of the pancreas. Perioperative as well as clinicopathological parameters were evaluated.
Results: There were 20 patients (9 men, 11 women; mean age 58 years) identified. The primary tumor was located in the pancreatic head (n=9, 45%), in pancreatic tail (n=9, 45%), and in the papilla Vateri (n=2, 10%). Metastases were located in the liver (n=14, 70%), peritoneum (n=5, 25%), and omentum majus (n=2, 10%). Lymphnode metastases were present in 16 patients (80%). All patients received resection of their tumors together with metastasectomy. Pylorus preserving duodenopancreatectomy was performed in 8 patients, distal pancreatectomy in 8, duodenopancreatectomy in 2, and total pancreatectomy in 2. Morbidity was 45% and there was no perioperative mortality. Median postoperative survival was 10.7 months (2.6–37.7 months) which was not significantly different from a matched-pair group of patients who underwent pancreatic resection for UICC adenocarcinoma of the pancreas (median survival 15.6 months; =.1).
Conclusion: Pancreatic resection for M1 periampullary cancer of the pancreas can be performed safely in well-selected patients. However, indication for surgery has to be made on an individual basis.
Tento ĉlánek se zabývá sémantikou německých ĉástic wohl a vielleicht a ĉeské ĉástice snad ve zvolacích větách. Uvádí se argumenty pro analýzu, podle které si v těchto typech vět – na rozdíl od jiných – zachovaly tyto ĉástice svoje pŧvodní "zesilující" významy, a proto by tento kontext měl být povaţován za autonomní. Dále ĉlánek podává vysvětlení pro toto sémantické/pragmatické chování.

Paul Scheerbarts astrale Hermeneutik : Vorschlag zu einer Bestimmung des Begriffs "Neoromantik"
(2010)
Im Februar 1904 erscheint in der Zeitschrift "Kunst" eine Reihe von Zeichnungen Paul Scheerbarts unter dem Titel "Der magnetische Spiegel". Eingebettet in einen pseudodokumentarischen Rahmentext illustrieren Kopffüßler und andere groteske Kreaturen den Erfahrungsbericht eines optisch-physikalischen Versuchs. Mit Hilfe einer in Schottland entdeckten Bauanleitung konstruiert der namenlose Berichterstatter einen magnetischen Spiegel, der ihm den Blick auf eine neue Kunst ermöglicht:
Rein äußerlich betrachtet, sind die geheimnisvollen Spiegel ganz einfache, spiegelnde Metallplatten. Wird nun die nach der Vorschrift hergestellte Metallplatte zur Erdbebenzeit in die richtige Lage gebracht, so zeigt sich bei Beobachtung der Platte mit eigens präparierter Lupe ein Bild von besonderer Anziehungskraft. Und wer diese Bilder in den Hauptzügen richtig zu kopieren vermag, der hat die "neue Kunst" entdeckt.
Magnetismus und 'neue Kunst' verweisen auf eine romantische Poetik und deren Projekt einer wissenschaftlichen Erforschung des Paranormalen; ein solches Amalgam von Technologie und esoterischem Wissen zielt auf eine naturwissenschaftliche Metaphysik und die Sichtbarmachung des Unsichtbaren.
The aim of this study was to investigate the frequency and effects of peer-victimization on mental health problems among adolescents. Parental and school support were assumed as protective factors that might interact with one another in acting as buffers for adolescents against the risk of peer-victimization. Besides these protective factors, age and gender were additionally considered as moderating factors. The Social and Health Assessment survey was conducted among 986 students aged 11-18 years in order to assess peer-victimization, risk and protective factors and mental health problems. For mental health problems, the Strengths and Difficulties Questionnaire (SDQ) was used. Effects of peer-victimization on mental health problems were additionally compared with normative SDQ data in order to obtain information about clinically relevant psychopathology in our study sample. Results of this study show that peer-victimization carries a serious risk for mental health problems in adolescents. School support is effective in both male and female adolescents by acting as a buffer against the effect of victimization, and school support gains increasing importance in more senior students. Parental support seems to be protective against maladjustment, especially in peer-victimized girls entering secondary school. Since the effect of peer-victimization can be reduced by parental and school support, educational interventions are of great importance in cases of peer-victimization.
L’étude s’inscrit dans le cadre de la valorisation des bois sacrés dans un contexte de conservation de la biodiversité, elle a pour objectifs de recenser les différents bois sacrés au nord du Burkina Faso, d’évaluer leur richesse floristique et d’appréhender leurs mécanismes de gestion par les populations locales. Des prospections ont été conduites sur l’ensemble de la zone d’étude en vue de recenser les bois sacrés. Dans chaque localité des enquêtes ont été conduites auprès des populations directement ou indirectement impliquées dans la gestion de ces formations. Des relevés phytosociologiques ont été réalisés dans les différentes formations végétales (bois sacrés et formations adjacentes) suivant la méthode Braun-Blanquet (1932) sur des placeaux de 1000 m2 et de 100 m2 respectivement pour les ligneux et les herbacées, en vue de déterminer les différentes phytocoenoses. 190 bois sacrés ont été recensés dont 35 ont fait l’objet d’inventaires phytosociologiques. 35 formations adjacentes ont également fait l’objet d’inventaires afin de mieux apprécier l’importance des bois sacrés dans la conservation des espèces. Le traitement des données phytosociologiques s’est effectué sur la base de 162 relevés, au moyen du logiciel CAP (Community Analysis Package). Les résultats ont révélé que les systèmes de gestion des ressources naturelles dans les bois sacrés sont basés sur des règles et des principes traditionnels. Ces bois sont pour la plupart des cimetières (50% du total), fétiches (17% du total) et fétiche-cimetières (27% du total). Le traitement des données phytosociologiques a permis de discriminer 11 groupements végétaux dont 05 pour la strate ligneuse et 06 pour la strate herbacée. Les relevés de 7 groupements ont été réalisés dans les bois sacrés et ceux de 4 groupements hors des bois sacrés. L’analyse de la richesse floristique d’ensemble (bois sacrés et environs) des ligneux a révélé la dominance de la famille des Leguminosae-Mimosoideae (16%) et des Combretaceae (12%). La flore herbacée quant à elle est dominée par les Poaceae (24%) et les Leguminosae- Papilionoideae (12%).
Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that are implicated in the regulation of lipid and glucose homeostasis. PPAR agonists have been shown to control inflammatory processes, in part by inhibiting distinct proinflammatory genes (e.g. Il-1β and IFN-γ). IL-8 is a member of the proinflammatory chemokine family that is important for various functions, such as mediating the adhesion of eosinophilic granulocytes onto endothelial cells. The influence of PPARδ activators on the expression of IL-8 in noninduced quiescent endothelial cells is unclear. Therefore, we explored the influence of PPARδ activators on the expression of IL-8 in nonstimulated endothelial cells. PPARδ agonists induce IL-8 expression in human umbilical vein endothelial cells. This induction is demonstrated at the level of both protein and mRNA expression. Transcriptional activation studies using IL-8 reporter gene constructs and DNA binding assays revealed that PPARδ agonists mediated their effects via an NFκB binding site. It is well known that IL-8 is also regulated by mRNA stability. To provide further evidence for this concept, we performed mRNA stability assays and found that PPARδ agonists induce the mRNA stability of IL-8. In addition, we showed that PPARδ agonists induce the phosphorylation of ERK1/2 and p38, which are known to be involved in the increase of mRNA stability. The inhibition of these MAPK signaling pathways resulted in a significant suppression of the induced IL-8 expression and the reduced mRNA stability. Therefore, our data provide the first evidence that PPARδ induces IL-8 expression in nonstimulated endothelial cells via transcriptional as well as posttranscriptional mechanisms.
