Wrack burial reduces germination and establishment of the invasive cordgrass Spartina densiflora
(2014)
Germination and emergence of halophytes may decrease significantly by seed burial in dead plant material, or wrack, which is common and abundant in tidal marshes. The effects of plant debris (wrack) burial on seed germination and seedling establishment of Spartina densiflora, an invasive cordgrass, were studied under greenhouse conditions and compared with field observations. Five wrack burial depths were applied: control without wrack, 1 cm (1235 ± 92 g DW wrack m-2), 2 cm (3266 ± 13 g DW m-2), 4 cm (4213 ± 277 g DW m-2), and 8 cm (6138 ± 227 g DW m-2). Sediment pH, electrical conductivity, redox potential and temperature were recorded. Quiescence increased with wrack load up to ~20% at 8 cm deep. Germination decreased with wrack load from 96% to 14%, which could be related with anoxic conditions under the debris since sediment redox potential was as low as -83 ± 7 mV at 8 cm. Germination percentage increased and quiescent and dormant percentages decreased at higher daily sediment temperatures and with higher daily temperature fluctuations, conditions that were recorded without or under low loads of wrack. Spartina densiflora did not show primary dormancy, but its seeds entered into a non-deep physiological dormancy below 1 cm deep in plant debris. The establishment of S. densiflora seedlings was also greatly reduced by wrack burial since only 6 seedlings (11 ± 5 % of germinated seeds) emerged above plant debris from 1 cm and all seedlings died from deeper than 1 cm. S. densiflora seedling development was also reduced by wrack burial. The inverse relationship between germination and emergence of S. densiflora with wrack burial recorded in our study is useful to predict its invasion dynamics and to plan the management of invaded marshes.
ALICE (A Large Ion Collider Experiment) is studying the physics of strongly interacting matter, and in particular the properties of the Quark–Gluon Plasma (QGP), using proton–proton, proton–nucleus and nucleus–nucleus collisions at the CERN LHC (Large Hadron Collider). The ALICE Collaboration is preparing a major upgrade of the experimental apparatus, planned for installation in the second long LHC shutdown in the years 2018–2019. These plans are presented in the ALICE Upgrade Letter of Intent, submitted to the LHCC (LHC experiments Committee) in September 2012. In order to fully exploit the physics reach of the LHC in this field, high-precision measurements of the heavy-flavour production, quarkonia, direct real and virtual photons, and jets are necessary. This will be achieved by an increase of the LHC Pb–Pb instant luminosity up to 6×1027 cm−2s−1 and running the ALICE detector with the continuous readout at the 50 kHz event rate. The physics performance accessible with the upgraded detector, together with the main detector modifications, are presented.
A measurement of the transverse momentum spectra of jets in Pb-Pb collisions at sNN−−−√=2.76 TeV is reported. Jets are reconstructed from charged particles using the anti-kT jet algorithm with jet resolution parameters R of 0.2 and 0.3 in pseudo-rapidity |η|<0.5. The transverse momentum pT of charged particles is measured down to 0.15 GeV/c which gives access to the low pT fragments of the jet. Jets found in heavy-ion collisions are corrected event-by-event for average background density and on an inclusive basis (via unfolding) for residual background fluctuations and detector effects. A strong suppression of jet production in central events with respect to peripheral events is observed. The suppression is found to be similar to the suppression of charged hadrons, which suggests that substantial energy is radiated at angles larger than the jet resolution parameter R=0.3 considered in the analysis. The fragmentation bias introduced by selecting jets with a high pT leading particle, which rejects jets with a soft fragmentation pattern, has a similar effect on the jet yield for central and peripheral events. The ratio of jet spectra with R=0.2 and R=0.3 is found to be similar in Pb-Pb and simulated PYTHIA pp events, indicating no strong broadening of the radial jet structure in the reconstructed jets with R<0.3.
Transverse momentum spectra of π±, K± and p(p¯) up to pT = 20 GeV/c at mid-rapidity in pp, peripheral (60–80%) and central (0–5%) Pb–Pb collisions at √sNN = 2.76 TeV have been measured using the ALICE detector at the Large Hadron Collider. The proton-to-pion and the kaon-to-pion ratios both show a distinct peak at pT ≈ 3 GeV/c in central Pb–Pb collisions. Below the peak, pT < 3 GeV/c, both ratios are in good agreement with hydrodynamical calculations, suggesting that the peak itself is dominantly the result of radial flow rather than anomalous hadronization processes. For pT > 10 GeV/c particle ratios in pp and Pb–Pb collisions are in agreement and the nuclear modification factors for π±, K± and p(p¯) indicate that, within the systematic and statistical uncertainties, the suppression is the same. This suggests that the chemical composition of leading particles from jets in the medium is similar to that of vacuum jets.
The ALICE Collaboration at the LHC reports measurement of the inclusive production cross section of electrons from semi-leptonic decays of beauty hadrons with rapidity |y| < 0.8 and transverse momentum 1 < pT < 10 GeV/c, in pp collisions at √s = 2.76 TeV. Electrons not originating from semi-electronic decay of beauty hadrons are suppressed using the impact parameter of the corresponding tracks. The production cross section of beauty decay electrons is compared to the result obtained with an alternative method which uses the distribution of the azimuthal angle between heavy-flavour decay electrons and charged hadrons. Perturbative QCD predictions agree with the measured cross section within the experimental and theoretical uncertainties. The integrated visible cross section, σb→e = 3.47 ± 0.40(stat) +1.12 −1.33(sys) ± 0.07(norm) μb, was extrapolated to full phase space using Fixed Order plus Next-to-Leading Log (FONLL) calculations to obtain the total bb production ¯ cross section, σbb¯ = 130 ± 15.1(stat) +42.1 −49.8(sys) +3.4 −3.1(extr) ± 2.5(norm) ± 4.4(BR) μb.
Event-by-event fluctuations of the mean transverse momentum of charged particles produced in pp collisions at s√ = 0.9, 2.76 and 7 TeV, and Pb-Pb collisions at sNN−−−−√ = 2.76 TeV are studied as a function of the charged-particle multiplicity using the ALICE detector at the LHC. Dynamical fluctuations indicative of correlated particle emission are observed in all systems. The results in pp collisions show little dependence on collision energy. The Monte Carlo event generators PYTHIA and PHOJET are in qualitative agreement with the data. Peripheral Pb-Pb data exhibit a similar multiplicity dependence as that observed in pp. In central Pb-Pb, the results deviate from this trend, featuring a significant reduction of the fluctuation strength. The results in Pb--Pb are in qualitative agreement with previous measurements in Au-Au at lower collision energies and with expectations from models that incorporate collective phenomena.
Freeze-out radii extracted from three-pion cumulants in pp, p–Pb and Pb–Pb collisions at the LHC
(2014)
In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose–Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted using two-pion correlations, and characterize the system at the last stage of interaction, called kinetic freeze-out. In low-multiplicity collisions, unlike in high-multiplicity collisions, two-pion correlations are substantially altered by background correlations, e.g. mini-jets. Such correlations can be suppressed using three-pion cumulant correlations. We present the first measurements of the size of the system at freeze-out extracted from three-pion cumulant correlations in pp, p–Pb and Pb–Pb collisions at the LHC with ALICE. At similar multiplicity, the invariant radii extracted in p–Pb collisions are found to be 5–15% larger than those in pp, while those in Pb–Pb are 35–55% larger than those in p–Pb. Our measurements disfavor models which incorporate substantially stronger collective expansion in p–Pb as compared to pp collisions at similar multiplicity.
We report on the measurement of the inclusive Υ (1S) production in Pb–Pb collisions at √sNN = 2.76 TeV carried out at forward rapidity (2.5 < y < 4) and down to zero transverse momentum using its μ+μ−decay channel with the ALICE detector at the Large Hadron Collider. A strong suppression of the inclusive Υ (1S) yield is observed with respect to pp collisions scaled by the number of independent nucleon–nucleon collisions. The nuclear modification factor, for events in the 0–90% centrality range, amounts to 0.30 ± 0.05(stat) ± 0.04(syst). The observed Υ (1S) suppression tends to increase with the centrality of the collision and seems more pronounced than in corresponding mid-rapidity measurements. Our results are compared with model calculations, which are found to underestimate the measured suppression and fail to reproduce its rapidity dependence.
We report on a polarization measurement of inclusive J/ψ mesons in the di-electron decay channel at mid-rapidity at 2 < pT < 6 GeV/c in p + p collisions at √s = 200 GeV. Data were taken with the STAR detector at RHIC. The J/ψ polarization measurement should help to distinguish between different models of the J/ψ production mechanism since they predict different pT dependences of the J/ψ polarization. In this analysis, J/ψ polarization is studied in the helicity frame. The polarization parameter λθ measured at RHIC becomes smaller towards high pT , indicating more longitudinal J/ψ polarization as pT increases. The result is compared with predictions of presently available models.
Symbiotic nitrogen fixation (SNF) in root nodules of grain legumes such as chickpea is a highly complex process that drastically affects the gene expression patterns of both the prokaryotic as well as eukaryotic interacting cells. A successfully established symbiotic relationship requires mutual signaling mechanisms and a continuous adaptation of the metabolism of the involved cells to varying environmental conditions. Although some of these processes are well understood today many of the molecular mechanisms underlying SNF, especially in chickpea, remain unclear. Here, we reannotated our previously published transcriptome data generated by deepSuperSAGE (Serial Analysis of Gene Expression) to the recently published draft genome of chickpea to assess the root- and nodule-specific transcriptomes of the eukaryotic host cells. The identified gene expression patterns comprise up to 71 significantly differentially expressed genes and the expression of twenty of these was validated by quantitative real-time PCR with the tissues from five independent biological replicates. Many of the differentially expressed transcripts were found to encode proteins implicated in sugar metabolism, antioxidant defense as well as biotic and abiotic stress responses of the host cells, and some of them were already known to contribute to SNF in other legumes. The differentially expressed genes identified in this study represent candidates that can be used for further characterization of the complex molecular mechanisms underlying SNF in chickpea.
Physics at its core is an experimental pursuit. If one theory does not agree with experimental results, then the theory is wrong. However, it is becoming harder and harder to directly test some theories of fundamental physics at the high energy/small distance frontier exactly because this frontier is becoming technologically harder to reach. The Large Hadron Collider is getting near the limit of what we can do with present accelerator technology in terms of directly reaching the energy frontier. The motivation for this special issue was to try and collect together ideas and potential approaches to experimentally probe some of our ideas about physics at the high energy/small distance frontier. Some of the papers in this special issue directly deal with the issue of what happens to spacetime at small distance scales. In the paper by A. Aurilia and E. Spallucci a picture of quantum spacetime is given based on the effects of ultrahigh velocity length contractions on the structure of the spacetime. The work of P. Nicolini et al. further pursues the idea that spacetime has a minimal length. The consequences of this minimal length are investigated in terms of the effects it would have on the gravitational collapse of a star to form a black hole. In the article by G. Amelino-Camelia et al. the quantum structure of spacetime is studied through the Fermi LAT data on the Gamma Ray Burst GRB130427A. The article by S. Hossenfelder addressed the question of whether spacetime is fundamentally continuous or discrete and postulates that in the case when spacetime is discrete it might have defects which would have important observational consequences. ...
So-called medicanes (Mediterranean hurricanes) are meso-scale, marine, and warm-core Mediterranean cyclones that exhibit some similarities to tropical cyclones. The strong cyclonic winds associated with medicanes threaten the highly populated coastal areas around the Mediterranean basin. To reduce the risk of casualties and overall negative impacts, it is important to improve the understanding of medicanes with the use of numerical models. In this study, we employ an atmospheric limited-area model (COSMO-CLM) coupled with a one-dimensional ocean model (1-D NEMO-MED12) to simulate medicanes. The aim of this study is to assess the robustness of the coupled model in simulating these extreme events. For this purpose, 11 historical medicane events are simulated using the atmosphere-only model, COSMO-CLM, and coupled model, with different setups (horizontal atmospheric grid-spacings of 0.44°, 0.22°, and 0.08°; with/without spectral nudging, and an ocean grid-spacing of 1/12°). The results show that at high-resolution, the coupled model is able to not only simulate most of medicane events but also improve the track length, core temperature, and wind speed of simulated medicanes compared to the atmosphere-only simulations. The results suggest that the coupled model is more proficient for systemic and detailed studies of historical medicane events, and that this model can be an effective tool for future projections.
Endoscopic retrograde cholangiopancreatography (ERCP) offers an effective interventional option for treating symptomatic chronic pancreatitis. Endoscopic pancreatic sphincterotomy is performed to facilitated endoscopic treatment. Pancreatic duct strictures can be treated by inserting plastic stents, and a 10 Fr endoprosthesis is adequate in many cases. Before stent insertion, hydrostatic balloon dilation is needed in some cases. Pancreatic stones can be removed with a dormia basket, but combining ERCP and extracorporeal shockwave lithotripsy (ESWL) is often most effective.
Standard and advanced endoscopic treatment approaches are delineated in this article and include stricture dilation with a Soehendra retriever, cSEMS placement and multi-stenting.
The answer to the question – Which can be the best way to teach and to learn to understand foreign people and culture in ethnically, culturally and linguistically homogenous teaching contexts? – is simple: through language teaching and learning. This process is per definitionem the encounter between a culture of origin and a target culture. The process of learning and teaching foreign languages generates the encounter with languages and cultures, which implies on the one hand a comparison of different cultural contexts and on the other hand self-reflection.
Starting from data, which were collected based on a survey, the present contribution attempts to answer the following questions:
1. What is the role of foreign language teachers in ethnically, culturally and linguistically homogenous teaching contexts?
2. To what extent do foreign language teachers and students perceive the intercultural dimensions of foreign language education in such contexts?
pH and Na+ homeostasis in all cells requires Na+/H+ antiporters. The crystal structure, obtained at pH 4, of NhaA, the main antiporter of Escherichia coli, has provided general insights into an antiporter mechanism and its unique pH regulation. Here, we describe a general method to select various NhaA mutants from a library of randomly mutagenized NhaA. The selected mutants, A167P and F267C are described in detail. Both mutants are expressed in Escherichia coli EP432 cells at 70–95% of the wild type but grow on selective medium only at neutral pH, A167P on Li+ (0.1 M) and F267C on Na+ (0.6 M). Surprising for an electrogenic secondary transporter, and opposed to wild type NhaA, the rates of A167P and F267C are almost indifferent to membrane potential. Detailed kinetic analysis reveals that in both mutants the rate limiting step of the cation exchange cycle is changed from an electrogenic to an electroneutral reaction.
Fluctuations of the water level at the edges of temporary water bodies provide favourable living conditions for annual plant communities of the phytosociological class Isoëto-Nanojuncetea. Such communities of periodically flooded ponds within the agricultural landscape of NE Germany are particularly rich in rare plant species of that class. During the past decades drainage, fertilisation and herbicides in the surrounding arable fields have led to a severe decline in diversity of these species. To develop efficient conservation strategies it is essential to understand the factors driving the species composition. Therefore, we studied how varying water regimes, soil properties and agricultural practices affect the diversity and species composition of these temporary ponds. The study was carried out in seven ponds on a conventionally managed farm in NE Brandenburg. At each of these wetlands mixed soil samples were taken to determine the pH, total nitrogen and phosphorus concentration. The plant species were recorded in 177 plots, each covering 1 x 1 m2. For each plot, the water level was recorded in April, July and August 2013, respectively, resulting in five "water level regimes". Total species number and percentages of Isoëto-Nanojuncetea species were determined per plot, to evaluate water level effects on the vegetation. In addition, mean Ellenberg indicator values for light, moisture and nutrients were calculated to assess the environmental conditions.
During an entomological survey in Santiago Island, Cape Verde Islands, in November-December 2011 in order to study the bio-ecology and susceptibility to insecticides of Anopheles arabiensis Patton, 1905, Culex tritaeniorhynchus Giles, 1901 was found to be present in the Santa Cruz District. Both adult and immature specimens were collected and a description of both is given. Further confirmation of the taxonomic identity of the specimens was obtained from studying the male genitalia. This is the first known occurrence of Culex tritaeniorhynchus (a primary vector of Japanese encephalitis in eastern and southern Asia and a potential vector of West Nile Virus, Sindbis and Rift Valley Fever Virus) in the Cape Verde Islands.
It has become increasingly apparent over the last decades that cooking pottery played a considerable role as a trade commodity in ancient times, yet relatively little research has yet been done on this topic for its own sake. By taking a closer look at the cooking pottery found in Priene, a small city in southern Ionia re-founded in the middle of the 4th century BCE, we want to trace some of the broader developments within the cooking wares that were used over a period of roughly 300 years. The aim is not only to outline the general shapes that were in use over this period of time, but also to register if and how these shapes correlate with the different fabrics observed in Priene so far.
OBJECTIVES: Outcome of aortic valve replacement may be influenced by the choice of bioprosthesis. Pericardial heart valves are described to have a favourable haemodynamic profile compared with porcine valves, although the clinical notability of this finding is still controversially debated. Herein, we compared the long-term results of two commonly implanted bioprosthesis at a single centre.
METHODS: All consecutive patients undergoing isolated aortic valve replacement with either a Carpentier-Edwards Magna pericardial prosthesis or a Medtronic Mosaic porcine prosthesis between 2002 and 2008 were analysed regarding preoperative characteristics, short- and long-term survival, valve-related complications and echocardiographic findings.
RESULTS: The Medtronic Mosaic was implanted in 163 patients and the Carpentier-Edwards Magna in 295 patients. The sizes of implanted valves were 22.4 ± 1.5 mm for the Mosaic and 21.8 ± 1.8 mm for the Magna (P = 0.001). The long-term survival rate was 76 and 56% after 5 and 10 years for the Medtronic Mosaic, which was comparable with the Carpentier-Edwards Magna (77 and 57%; P = 0.92). Overall long-term survival was comparable with an age- and sex-matched Austrian general population for both groups. Valve-related adverse events were similar between groups. The postoperative mean transvalvular gradient was significantly increased in the Mosaic group (24 ± 9 mmHg vs 17 ± 7 mmHg; P < 0.001).
CONCLUSIONS: Both types of aortic bioprostheses offer excellent results after isolated aortic valve replacement. Despite relevant differences in gradients, long-term survival was comparable with the expected normal survival for both bioprostheses. Patients with a porcine heart valve had a higher postoperative transvalvular gradient.
Anhand von zwei auf Deutsch verfassten essayistischen Texten von Jiří Gruša - 'Beneš als Österreicher' (2012) und 'Die Gebrauchsanweisung für Tschechien und Prag' (2003) - wird gezeigt, wie die Konzepte von Nationalgeschichte und Nationalliteratur an ihre Grenzen gebracht werden können: Durch vervielfältigende, ironisierende und verdichtende Verfahren werden nationale Selbst-Behauptungen entstellt, sowie die Konstitution und Funktion kollektiver Identitätsnarrative ausgestellt. Während in der Gebrauchsanweisung ausgerechnet ein 'pluralis nationalis' die Selbstvergewisserungen subvertiert, zeigt sich im bzw. durch den Beneš-Essay, wie die Erzählungen der Figur Beneš die Geister der Nation scheiden. Insofern werden die beiden Texte als Beispiele dafür gelesen, wie durch Schreibstrategien, aber auch angesichts editionsgeschichtlicher Zusammenhänge sowie im Hinblick auf die Rezeption eindeutige Zuweisungen zu einer Nationalliteratur oder Nationalgeschichte in Frage gestellt werden.
Friedrich Kittler gilt als "Begründer einer der eigenwilligsten und zugleich umstrittensten Medientheorien." Bekannt wurde er mit seiner Frühschrift 'Austreibung des Geistes aus den Geisteswissenschaften' von 1980, wo er den Geist aus den Geisteswissenschaften zugunsten von Naturwissenschaft und Technik austreiben wollte. Gegen dieses Phantom ging dann auch seine spätere Schrift 'Grammophon, Film, Typewriter' von 1986 an, um den Geist endgültig in den "Schaltungen" dingfest zu machen. Denn, so heißt es wenig später, "nichts ist, was nicht schaltbar ist". Aber nicht dieses "technische Apriori" hat ihm den Ruf eingebracht, sondern dass er alle zivile Medientechnik von der Kriegstechnologie herleitete. Darüber hinaus lautet ein gegen Kittler vorgebrachter Einwand, er verwechsle die technischen, mathematischen, formalen Sprachen der Medien mit symbolischen Sprachen, mit Bedeutung, Sinn, Denken, Deutung, Reden und Kommunikation. Diese Verwechselung funktioniert dann nach dem Dualismus - denn von Dialektik kann man hier kaum noch reden - von Wesen und Erscheinung, wobei hinter der medialen Erscheinung immer das Wesen der Medien als militärische Natur steckt.
Genau diese Interpretation von Kittlers Medientheorie - obwohl sie nicht ganz falsch liegt - geht aber, wie ich zeigen möchte, an Kittlers Denken vorbei, wie wir inzwischen auch dem Buch 'Die Wahrheit der technischen Welt' entnehmen können, wie aber spätestens seit 'Musik und Mathematik I/1' oder 'Musen, Nymphen und Sirenen' ganz deutlich wurde. So zeigen auch die dreiundzwanzig zwischen 1978 und 2010 veröffentlichten Kittler-Essays, die das neue Buch zusammenbringt, dass das "technologische Kriegswesen" hinter der Erscheinung nur eine Tarnung war.
Dendritic cells (DCs) are the cutting edge in innate and adaptive immunity. The major functions of these antigen-presenting cells are the capture, endosomal processing and presentation of antigens, providing them an exclusive ability to provoke adaptive immune responses and to induce and control tolerance. Immature DCs capture and process antigens, migrate towards secondary lymphoid organs where they present antigens to naive T cells in a well-synchronized sequence of procedures referred to as maturation. Indeed, recent research indicated that sphingolipids are modulators of essential steps in DC homeostasis. It has been recognized that sphingolipids not only modulate the development of DC subtypes from precursor cells but also influence functional activities of DCs such as antigen capture, and cytokine profiling. Thus, it is not astonishing that sphingolipids and sphingolipid metabolism play a substantial role in inflammatory diseases that are modulated by DCs. Here we highlight the function of sphingosine 1-phosphate (S1P) on DC homeostasis and the role of S1P and S1P metabolism in inflammatory diseases.
Antigenic and 3D structural characterization of soluble X4 and hybrid X4-R5 HIV-1 Env trimers
(2014)
Background: HIV-1 is decorated with trimeric glycoprotein spikes that enable infection by engaging CD4 and a chemokine coreceptor, either CCR5 or CXCR4. The variable loop 3 (V3) of the HIV-1 envelope protein (Env) is the main determinant for coreceptor usage. The predominant CCR5 using (R5) HIV-1 Env has been intensively studied in function and structure, whereas the trimeric architecture of the less frequent, but more cytopathic CXCR4 using (X4) HIV-1 Env is largely unknown, as are the consequences of sequence changes in and near V3 on antigenicity and trimeric Env structure.
Results: Soluble trimeric gp140 Env constructs were used as immunogenic mimics of the native spikes to analyze their antigenic properties in the context of their overall 3D structure. We generated soluble, uncleaved, gp140 trimers from a prototypic T-cell line-adapted (TCLA) X4 HIV-1 strain (NL4-3) and a hybrid (NL4-3/ADA), in which the V3 spanning region was substituted with that from the primary R5 isolate ADA. Compared to an ADA (R5) gp140, the NL4-3 (X4) construct revealed an overall higher antibody accessibility, which was most pronounced for the CD4 binding site (CD4bs), but also observed for mAbs against CD4 induced (CD4i) epitopes and gp41 mAbs. V3 mAbs showed significant binding differences to the three constructs, which were refined by SPR analysis. Of interest, the NL4-3/ADA construct with the hybrid NL4-3/ADA CD4bs showed impaired CD4 and CD4bs mAb reactivity despite the presence of the essential elements of the CD4bs epitope. We obtained 3D reconstructions of the NL4-3 and the NL4-3/ADA gp140 trimers via electron microscopy and single particle analysis, which indicates that both constructs inherit a propeller-like architecture. The first 3D reconstruction of an Env construct from an X4 TCLA HIV-1 strain reveals an open conformation, in contrast to recently published more closed structures from R5 Env. Exchanging the X4 V3 spanning region for that of R5 ADA did not alter the open Env architecture as deduced from its very similar 3D reconstruction.
Conclusions: 3D EM analysis showed an apparent open trimer configuration of X4 NL4-3 gp140 that is not modified by exchanging the V3 spanning region for R5 ADA.
In diesem Beitrag wird der Sprach(en)gebrauch der venezianischen Juden im 16./17. Jhd. untersucht. Dabei geht es um die Sprachen der verschiedenen jüdischen Gruppen, die gemeinsam im neu eingerichteten Ghetto wohnten. Insbesondere wird der Frage nachgegangen, welchen Gebrauch sie von unterschiedlichen Sprachen/Varietäten in unterschiedlichen kommunikativen Situationen und zu unterschiedlichen Zwecken gemacht haben. Dabei traten selbstverständlich auch Sprachmischungen auf, die von unbewussten Interferenzen über Entlehnungen (aus dem Hebräischen/Aramäischen, aber auch aus dem Venezianischen und den anderen von Juden gesprochenen Sprachen), bis hin zu ganz bewusst verwendeter Zwei- und Mehrsprachigkeit in literarischen Texten z. B. mit sprachspielerischer Absicht reichen. Die verschiedenen Textsorten, die hierzu analysiert werden (etwa Texte religiösen Inhalts, Testamente, Grabinschriften und Gedichte), spiegeln auf vielfältige Weise zugleich das Sprach- und Sprachenbewusstsein der venezianischen Juden jener Zeit wider.
Dieser Beitrag untersucht die Beziehung zwischen den Diskursen Literatur und Recht in der deutschsprachigen Gegenwartsliteratur. Ausgehend von der langen Tradition der sogenannten Dichterjuristen (Goethe, Kleist, Kafka) werden aktuelle Tendenzen dieser Beziehung in den Blick genommen. Nach theoretischen Überlegungen zum Teilaspekt law in literature (Recht in der Literatur) erfolgt die Bestimmung von spezifischen Themen, Genres und ästhetischen Besonderheiten der in Frage stehenden Texte. Als Textgrundlage dienen Romane von Juli Zeh und Ferdinand von Schirach. In dieser Analyse werden auch die Adaptionen für Kino und TV einbezogen (die Serie "Verbrechen" für den TV-Sender ZDF, die auf Ferdinand von Schirachs gleichnamiger Kurzgeschichtensammlung beruht, und die Miniserie "A Menina sem Qualidades", eine Adaption von Juli Zehs "Spieltrieb" für MTV Brasilien).

(2014)
Bu çalışmada Türkiye'nin akademik açık erişim dergi yayıncılığında geldiği noktayı ortaya koymak, 70'li yıllardan itibaren dilbilim ve filolojiden ayrılarak kendi bilimsel çerçevesini çizen ve kendi bilimsel iletişim sistemini oluşturan Çeviribilim alanının, bilimsel iletişim sisteminin en önemli araçlarından biri olan akademik açık erişim dergicilik konusunda aldığı mesafeyi görmek, bu konuda mevcut eksiklikleri tespit etmek ve bunlara çözüm önerilerinde bulunmak amaçlanmaktadır. Bu amaçla ulusal ve uluslararası açık erişim veritabanları incelenerek elde edilen bilgiler değerlendirilmeye çalışıldı. Çalışmanın birinci aşamasında Türkiye'nin akademik açık erişim dergicilik konusundaki mevcut durumu değerlendirilirken ikinci aşamada Çeviribilim alanının durumu ele alındı. Son aşamada ise elde edilen verilerden anlamlı sonuçlar çıkarılarak genel bir değerlendirme yapıldı ve çeşitli öneriler sunuldu.
"Von einer Vereinigung des Christenthums mit der Philosophie kann ich mir nichts Bestimmtes denken", schreibt Friedrich Schleiermacher am 28. März 1801 an Friedrich Heinrich Christian Schwarz, den später nach Heidelberg berufenen Theologen und Pädagogen. "Was wollen Sie vereinigen, wo gar kein Streit ist? Die Religion kann nicht umhin, die philosophierende Anlage im Menschen anzuerkennen, und das tut sie auch wohl jetzt durchaus; und ebenso kann man die Philosophie nötigen, die religiöse Stimmung anzuerkennen, wenn sie sich gleich etwas ungebärdig dabei anstellt." Man glaubt in diesen Worten das irenische, zum Ausgleich geneigte Gemüt Schleiermachers zu vernehmen, welches gleichwohl nicht hat verhindern können, dass er mehrfach in seinem Leben in heftigen religiösen, politischen und literarischen Streit verwickelt wurde.
In seinen Worten klingt jedoch auch noch das Bewusstsein nach, dass die Harmonie von Philosophie und Religion, falls es sie überhaupt gibt, jedenfalls jüngeren Datums ist. Die Philosophie stellt sich immer noch ungebärdig dabei an, die religiöse Stimmung anzuerkennen. Umgekehrt scheint die Religion eben erst jetzt - um 1800 - ihren Frieden mit der philosophierenden Anlage im Menschen gemacht zu haben. Man muss hier nicht unbedingt an jene jahrtausendealte Tradition der Auseinandersetzung zwischen Philosophie und Religion denken, die wir heute noch mit dem Stichwort Athen vs. Jerusalem bezeichnen.
Es genügt, sich ans 17. und 18. Jahrhundert zu erinnern, an die philosophes, die kritischen Intellektuellen Frankreichs, die einen zähen, nach und nach immer besser organisierten Kampf gegen die katholische Kirche führen, oder an die nach der Massenflucht der Hugenotten aus Frankreich vor und nach 1685 und der Glorious Revolution (1688) besonders in England und den niederländischen vereinigten Provinzen intensiv und erbittert geführte Debatte über religiöse Toleranz und katholische wie protestantische Intoleranz.
Immatrikulationsfeiern gehörten zum festen Ritual der universitären Kultur, bis in den 1960er Jahren bewusst mit dieser Tradition gebrochen wurde. Heute werden die Studierenden an der Goethe-Universität beim "unistart" begrüßt. Ist diese Veranstaltung ein Brückenschlag zwischen Gegenwart und alten Zeiten oder eher ein Spiegel des sich wandelnden universitären Selbstverständnisses?
If we take Benjamin's definitions to their logical conclusion, then the monad and the reproduced copy are set unequivocally into binary opposition, as we, the masses capable and most needful of action, are implicitly denied the potential for liberation through aesthetic experience. This denial could not have been his long-term intention. When we take into account the breadth of his writings in response to Fascism, and we look at the artistic movements, Dada in particular, that Benjamin defines as 'politicizing art,' it seems as though we risk too narrow a reading of Benjamin's theories by assuming the aura can be, or must be, done away with. Rather, I would argue that this moment of auratic interaction is crucial to effectively politicizing art at all. Mechanically-produced art, in order to function politically, must allow its audience the space necessary to step back, awaken their 'Geistesgegenwart', and take action 'before' the present moment is finished and past. The elimination of aura - as per Benjamin’s own definitions of aura - neuters the interaction this awakening requires. While Benjamin provides the framework and asks the right questions, when determining what will allow his definitions to realize their aims most fully, I submit that he draws his line in the wrong place.
Seit Mitte des 18. Jahrhunderts werden das Volkslied und die Ballade als Ausdruck der Natur verstanden, der unvermittelt und darum echt ist. Doch nicht nur editorische Eingriffe im Zuge der Herausgabe dieser zumeist nur vermeintlich mündlich tradierten Dichtung lassen die Echtheit der Texte problematisch erscheinen. In der Kunstballadendichtung bildet sich zu Beginn des 19. Jahrhunderts der so genannte Volksliedton heraus. Die epigonale oder ironische Imitation dieses einfachen Stils kann nicht mehr im Paradigma der Herder'schen Ausdrucksästhetik verstanden werden. Insbesondere Heinrich Heines Lieder gelten als ironische Nachahmung volksliedhafter Dichtung und als Ausweis, dass diese Form von "Lied [...] keine authentische Kunst" sei.
Heine verhandelt die Problematik der Echtheit in seinen Schriften zu Volkslied und Ballade über die zentralen Begriffe des Diskurses - Einfachheit und Wahrhaftigkeit. Er verwirft diese Konzepte jedoch nicht einfach, sondern modifiziert sie. Heine, so soll im Folgenden gezeigt werden, variiert die Idee eines 'echten' Volksliedes, indem er den Gedanken ausprägt, bestimmte Texte stünden im Zeichen eines "Geist[es] der Volkslied-Formen". Die Problematik der Wahrhaftigkeit verhandelt Heine in 'Die romantische Schule' sowie in seinem Buch der Lieder im Bild der Kostümierung und Maskierung. Sie wird hier zur Frage der Ehrlichkeit und Treue, die interpersonell und kommunikativ gefasst ist.
Background: Hereditary angioedema (HAE) due to C1 inhibitor deficiency is a rare but serious and potentially life-threatening disease marked by spontaneous, recurrent attacks of swelling. The study objective was to characterize direct and indirect resource utilization associated with HAE from the patient perspective in Europe.
Methods: The study was conducted in Spain, Germany, and Denmark to assess the real-world experience of HAE via a cross-sectional survey of HAE patients, including direct and indirect resource utilization during and between attacks for patients and their caregivers over the past 6 months. A regression model examined predictors of medical resource utilization.
Results: Overall, 164 patients had an attack in the past 6 months and were included in the analysis. The most significant predictor of medical resource utilization was the severity of the last attack (OR 2.6; p < 0.001). Among patients who sought medical care during the last attack (23%), more than half utilized the emergency department. The last attack prevented patients from their normal activities an average of 4-12 hours. Patient and caregiver absenteeism increased with attack severity and frequency. Among patients who were working or in school (n = 120), 72 provided work/school absenteeism data, resulting in an estimated 20 days missing from work/school on average per year; 51% (n = 84) indicated that HAE has hindered their career/educational advancement.
Conclusion: HAE poses a considerable burden on patients and their families in terms of direct medical costs and indirect costs related to lost productivity. This burden is substantial at the time of attacks and in between attacks.
Schiller'in Edebiyat Görüşü
(2014)
Schiller'in edebiyat üzerine yazdığı makalesi "Über naive und sentimentalische Dichtung", Goethe ile yakın ve verimli dostluğuna dayanır. Mektuplaşmalarında eserleri hakkında karşılıklı ifadeleri bunu göstermektedir. Schiller'in çıkardığı "Die Horen" adlı edebi ve felsefi dergi, Goethe'nin katkısıyla nerdeyse Alman Klasisizminin program dergisi olmuştur. Felsefeye olan büyük merakı ile Schiller Goethe'nin eserlerini ve "Horen" dergisindeki yazılarını okuyunca, kendisi ile onun arasında önemli bir farkı keşfetmek durumunda kalmıştır. Doğalcı ve düşünselci edebiyat hakkında yazdığı görüşleri bunun kanıtlarıdır.
An extensive survey of the relevant literature of dry grassland communities described for the territory of Serbia allowed us to check the validity and legitimacy of the nomenclature of this vegetation. Nomenclature rules of the International Code of Phytosociological Nomenclature were strictly followed. The syntaxonomic affiliation of communities to higher syntaxa was assessed according to existing syntaxonomic schemes for Serbia and the position determined by the original source. Higher syntaxa followed the synsystem of the socalled “EuroVegChecklist”. We have highlighted problems and some disagreement with the existing classification of dry grassland communities in Europe. A total of 134 dry grassland communities have so far been registered for Serbia. This list of syntaxa may serve for further research of grassland vegetation and its appropriate positioning within a syntaxonomical scheme of Europe.
"wir haben ein land aus worten." In Semier Insayif Roman 'Faruq' (2009) geht es um Worte und Erinnerungen, um das (Nicht-)Sprechen-Können und darum, Sprache und Gedächtnis zu verlieren. Es geht um das Schreiben, Sprechen und Rezitieren im Bereich des Dazwischen von Sprachen und Kulturen. Ausgehend von der Perspektive des Ich-Erzählers im Text entfalten sich die Nuancen und Facetten des Lebens als Geschichten, als Texturen der Erinnerung und als eine Art Sprach- und Klanggewebe. Bezugnehmend auf eben diese poetischen und rhetorischen Aspekte des Textes wird eine Lektüre unternommen, die auf postkolonialen und dekonstruktiven Ansätzen wie auch auf Gedächtnistheorien basiert. Die Lektüre versucht sowohl auf die Anforderungen und Besonderheiten des Textes in allen Facetten des Dazwischens zu reagieren als auch jene Perspektiven zu ergründen, die für die zeitgenössische Entwicklung der sogenannten Migrationsliteratur signifikant sind.
ND3, ND1 and 39kDa subunits are more exposed in the de-active form of bovine mitochondrial complex I
(2014)
An intriguing feature of mitochondrial complex I from several species is the so-called A/D transition, whereby the idle enzyme spontaneously converts from the active (A) form to the de-active (D) form. The A/D transition plays an important role in tissue response to the lack of oxygen and hypoxic deactivation of the enzyme is one of the key regulatory events that occur in mitochondria during ischaemia. We demonstrate for the first time that the A/D conformational change of complex I does not affect the macromolecular organisation of supercomplexes in vitro as revealed by two types of native electrophoresis. Cysteine 39 of the mitochondrially-encoded ND3 subunit is known to become exposed upon de-activation. Here we show that even if complex I is a constituent of the I+III2+IV (S1) supercomplex, cysteine 39 is accessible for chemical modification in only the D-form. Using lysine-specific fluorescent labelling and a DIGE-like approach we further identified two new subunits involved in structural rearrangements during the A/D transition: ND1 (MT-ND1) and 39kDa (NDUFA9). These results clearly show that structural rearrangements during de-activation of complex I include several subunits located at the junction between hydrophilic and hydrophobic domains, in the region of the quinone binding site. De-activation of mitochondrial complex I results in concerted structural rearrangement of membrane subunits which leads to the disruption of the sealed quinone chamber required for catalytic turnover.
Recent density functional theory (DFT) calculations for KFe2As2 have been shown to be insufficient to satisfactorily describe angle-resolved photoemission (ARPES) measurements as well as observed de Haas–van Alphen (dHvA) frequencies. In the present work, we extend DFT calculations based on the full-potential linear augmented plane-wave method by dynamical mean field theory (DFT+DMFT) to include correlation effects beyond the local density approximation. We present results for two sets of reported crystal structures. Our calculations indicate that KFe2As2 is a moderately correlated metal with a mass renormalization factor of the Fe $3{\rm d}$ orbitals between 1.6 and 2.7. Furthermore, the obtained shape and size of the Fermi surface are in good agreement with ARPES measurements and we observe some topological changes with respect to DFT calculations such as the opening of an inner hole cylinder at the Z point. As a result, our calculated dHvA frequencies differ greatly from existing DFT results and qualitatively agree with experimental data. On this basis, we argue that correlation effects are important to understand the -presently under debate- nature of the superconducting state in KFe2As2.
Na tragu učenja praške funkcionalne (aktualne) rečenične perspektive o osnovnom i aktualiziranom redu riječi razmatrat će se redoslijed sastavnica u složenim strukturama (subordiniranima i koordiniranima). U prvome redu zanimat će nas poredak surečenica (klauza) u sastavu zavisnosložene rečenice. Postavlja se naime pitanje čime sve može biti uvjetovana anteponiranost zavisne surečenice (tzv. inverzija), i to u različitim tipovima tekstova odnosno komunikacijskim situacijama (npr. u akademskom/ znanstvenom i/ili predavačkom diskursu, potom u privatnim razgovorima itd.). U tu svrhu pozornost ćemo obratiti na primjere poput ovih: Kao što je naslovom najavljeno, bavit ćemo se složenim rečenicama.; Kako bismo ubrzali objavljivanje zbornika, želja nam je što prije skupiti radove.; Kao što je prethodno rečeno, nastava počinje u listopadu.; Ako ne prekineš s glupostima, odlazim!; Dok ne ispraviš jedinice, ništa od izlazaka! i sl. Što se pak nezavisnosloženih rečenica tiče, ponajprije ćemo se suočiti s pitanjem utvrđivanja primarnog redoslijeda sastavnica (Sjedim i razmišljam. ili Razmišljam i sjedim.), da bismo potom pokušali utvrditi moguće razloge remećenja toga redoslijeda (npr. Umro – brao trešnje i pao sa stabla. prema Popeo se, brao trešnje, pao sa stabla, umro.). Naposljetku budući da pristajemo uz gledište da se već složena rečenica može smatrati činjenicom teksta (J. Silić), ali i zbog toga što se aktualizirani red riječi/komponenata ostvaruje upravo u (kon)tekstualno uključenoj rečenici, u svjetlu ćemo novije lingvistike teksta (R. de Beaugrande i W. Dressler) o redoslijedu komponenata promišljati kao o kohezivnom sredstvu.
Die Ermittlung und Bewertung der Auswirkungen von Stickstoffeinträgen in der FFH-Verträglichkeitsprüfung ist in Deutschland seit fast zehn Jahren Gegenstand einer intensiven Fachdiskussion. Zuletzt hat sich ein Forschungsprojekt im Auftrag der Bundesanstalt für Straßenwesen (BASt) mit dieser Frage beschäftigt und eine Fachkonvention für den Projekttyp Straße erarbeitet. Diese Fachkonvention, die auch auf andere Projekttypen übertragbar ist, basiert grundsätzlich auf dem Maßstab der Critical Loads zur Beschreibung der Empfindlichkeit von FFH-Lebensräumen gegenüber Stickstoffeintrag. Liegt die gebietsspezifische Gesamtbelastung mit Stickstoffeinträgen über dem standort- und vegetationstypspezifisch zu ermittelnden Critical Load, so wird für die FFH-Verträglichkeitsprüfung ein mehrstufiges Schwellenwertkonzept zur Bestimmung von irrelevanten bzw. bagatellhaften Zusatzbelastungen empfohlen: Unterschieden wird ein vorhabenbezogenes absolutes Abschneidekriterium von 0,3 kg N ha-1a-1 und eine rezeptorbezogene Bagatellschwelle von 3% des jeweiligen Critical Loads. Beide Schwellenwerte sind als sehr niedrig und der Zielsetzung der FFH-Richtlinie entsprechend vorsorgeorientiert einzustufen.Mit dem Bewertungsansatz werden alle Anforderungen, die sich aus den fachlichen und rechtlichen Maßstäben für die FFH-Verträglichkeitsprüfung ergeben, berücksichtigt. Zugleich handelt es sich um einen praxistauglichen Bewertungsansatz, der auch dem Grundsatz der Verhältnismäßigkeit Rechnung trägt. Das vorhabenbezogene Abschneidekriterium soll für jedes zu genehmigende Vorhaben gelten. Für die Größenordnung von 0,3kg N ha-1a-1 für den vorhabenbezogenen Stickstoffeintrag in ein FFH-Gebiet sprechen verschiedene Argumente: Einträge in dieser Größenordnung liegen deutlich unterhalb der messtechnischen Erfassbarkeit und deutlich unterhalb jeder bekannten Schwelle von Zusatzbelastungen, die negative Wirkungen für die Biodiversität auslösen können; unterhalb dieser Größenordnung ist eine Ermittlung von Belastungen und Beeinträchtigungen mit derzeit verfügbaren Modellen und Eingangsdaten auch aufgrund der Unsicherheiten und fehlenden statistischen Signifikanz nicht mehr sinnvoll möglich. Zusatzbelastungen eines Vorhabens in dieser Größenordnung stellen somit lediglich ein theoretisches Risiko dar und können keine erheblichen Beeinträchtigungen im Sinne der FFH-RL auslösen. Somit können auch nur diejenigen projektbezogenen Zusatzbelastungen, die oberhalb dieses Abschneidekriteriums liegen, für eine kumulative Prüfung mit weiteren Projekten und deren gemeinsamer Wirkung geprüft werden. Die Bagatellschwelle von 3% des Critical Loads wird demgegenüber gebietsbezogen angewendet und kann daher auch durch das Zusammenwirken mehrerer einzelner Vorhaben überschritten werden. Die Anwendung soll unabhängig von der Höhe der Überschreitung der Critical Loads in der Gesamtbelastung möglich sein. Die Bagatellschwelle ist an der spezifischen Stickstoffempfindlichkeit der FFH Lebensräume, die durch die Critical Loads vorsorgeorientiert beschrieben wird, ausgerichtet. Eine Auswertung der Ergebnisse der Wirkungsforschung, insbesondere zu Randeffekten entlang von Straßen, hat ergeben, dass der Wert von 3% des maßgeblichen Critical Loads sicher unterhalb von feststellbaren negativen Wirkungen auf den Erhaltungszustand von FFH-Lebensräumen liegt.

The n_TOF facility operates at CERN with the aim of addressing the request of high accuracy nuclear data for advanced nuclear energy systems as well as for nuclear astrophysics. Thanks to the features of the neutron beam, important results have been obtained on neutron induced fission and capture cross sections of U, Pu and minor actinides. Recently the construction of another beam line has started; the new line will be complementary to the first one, allowing to further extend the experimental program foreseen for next measurement campaigns.
The study of neutron-induced reactions is of high relevance in a wide variety of fields, ranging from stellar nucleosynthesis and fundamental nuclear physics to applications of nuclear technology. In nuclear energy, high accuracy neutron data are needed for the development of Generation IV fast reactors and accelerator driven systems, these last aimed specifically at nuclear waste incineration, as well as for research on innovative fuel cycles. In this context, a high luminosity Neutron Time Of Flight facility, n_TOF, is operating at CERN since more than a decade, with the aim of providing new, high accuracy and high resolution neutron cross-sections. Thanks to the features of the neutron beam, a rich experimental program relevant to nuclear technology has been carried out so far. The program will be further expanded in the near future, thanks in particular to a new high-flux experimental area, now under construction.
Autor, motiviran ponajprije poznatom pretpostavkom o tome da je Marko Marulić možda studirao pravne znanosti, prvo daje pregled dosadašnjih ograničenih pokušaja da se govori o pravnoj terminologiji u Marulićevu opusu na hrvatskom jeziku. Poslije se, s obzirom na to da se u prikazanoj literaturi katkada implicira (ali i eksplicira) da se Marulić koristi tim terminima zato što je bio pravnik, pretragom spomenutog opusa u potrazi za potencijalnim pravnim terminima pokušava utvrditi može li se takvo razmišljanje bolje potkrijepiti ili pak opovrgnuti. Na kraju se raspravlja o metodološkim problemima, ograničenjima, ali i mogućnostima poboljšanja takvih filoloških istraživanja.
Die Mitte der 1990er Jahre erfolgte Erfassung von Sedum villosum in Hessen wurde wiederholt. Die Vorkommen in der Rhön sind durch verringerte Weideintensität rückläufig. Ein Vorkommen ist hier offenbar erloschen. Das Vorkommen im Unteren Vogelsberg besteht weiterhin, obwohl die Standortbedingungen an einer Waldstraße ungünstig erscheinen. Das Vorkommen im Vorderen Vogelsberg ist erloschen. Ein zwischenzeitlich entdecktes Vorkommen in der Westhessischen Senke bei Alsfeld auf einem Basaltweg ist stabil; allerdings ist die Zukunftsprognose für dieses Vorkommen auf Grund von Brache negativ. Über die ersten Erfahrungen bei der Wiederansiedlung aus einer Erhaltungskultur wird berichtet.
Background: Risk stratification, detection of minimal residual disease (MRD), and implementation of novel therapeutic agents have improved outcome in acute lymphoblastic leukemia (ALL), but survival of adult patients with T-cell acute lymphoblastic leukemia (T-ALL) remains unsatisfactory. Thus, novel molecular insights and therapeutic approaches are urgently needed.
Methods: We studied the impact of B-cell CLL/lymphoma 11b (BCL11b), a key regulator in normal T-cell development, in T-ALL patients enrolled into the German Multicenter Acute Lymphoblastic Leukemia Study Group trials (GMALL; n = 169). The mutational status (exon 4) of BCL11b was analyzed by Sanger sequencing and mRNA expression levels were determined by quantitative real-time PCR. In addition gene expression profiles generated on the Human Genome U133 Plus 2.0 Array (affymetrix) were used to investigate BCL11b low and high expressing T-ALL patients.
Results: We demonstrate that BCL11b is aberrantly expressed in T-ALL and gene expression profiles reveal an association of low BCL11b expression with up-regulation of immature markers. T-ALL patients characterized by low BCL11b expression exhibit an adverse prognosis [5-year overall survival (OS): low 35% (n = 40) vs. high 53% (n = 129), P = 0.02]. Within the standard risk group of thymic T-ALL (n = 102), low BCL11b expression identified patients with an unexpected poor outcome compared to those with high expression (5-year OS: 20%, n = 18 versus 62%, n = 84, P < 0.01). In addition, sequencing of exon 4 revealed a high mutation rate (14%) of BCL11b.
Conclusions: In summary, our data of a large adult T-ALL patient cohort show that low BCL11b expression was associated with poor prognosis; particularly in the standard risk group of thymic T-ALL. These findings can be utilized for improved risk prediction in a significant proportion of adult T-ALL patients, which carry a high risk of standard therapy failure despite a favorable immunophenotype.
5-Lipoxygenase (5LO) is a key enzyme in biosynthesis of leukotrienes (LTs), lipid mediators of inflammation. To study the roles of the 5LO accessory proteins coactosin-like protein (CLP) and 5LO-activating protein (FLAP), we knocked down these proteins in human monocytic cells. Our results show that expression of CLP was required for full cellular 5LO activity when cells were activated with Ca2+ ionophore, as well as with a physiological stimulus (lipopolysaccharide followed by N-formylmethionyl-leucyl-phenylalanine). During LT biosynthesis in stimulated cells, 5LO typically translocates to the nuclear membrane. This redistribution, from cytosolic to perinuclear, was clearly compromised in both CLP- and FLAP-deficient cells. Our results suggest that the CLP–5LO interaction may be a target for reduced LT production.
U ovome će se radu dati uvod u optimalnosnu teoriju (engl. Optimality Theory, Prince i Smolensky 1991/1993, 2004), jednu od najznačajnijih suvremenih teorija jezika. Iako uživa najveći ugled među fonolozima, prikazat će je se kao opću jezičnu teoriju s naglaskom na njezinu primjenu u fonologiji. Prikazat će se kontekst njezina nastanka s obzirom na tada vodeću generativnu fonološku teoriju i naravnu fonologiju te će se predstaviti njezino polazište i ciljevi. Objasnit će se temeljni pojmovi optimalnosne teorije (ograničenja, obilježenost, vjernost, optimalnost) i pretpostavljeni model gramatike (input, output, generator, evaluator) te će se uvesti u princip jezične analize u njezinu teorijskom okviru, a analiza će se oprimjeriti na dvjema fonološkim pojavama – jednačenju šumnika po zvučnosti u suglasničkome skupu i obezvučivanju na kraju riječi.
We examined substrate-induced conformational changes in MjNhaP1, an archaeal electroneutral Na+/H+-antiporter resembling the human antiporter NHE1, by electron crystallography of 2D crystals in a range of physiological pH and Na+ conditions. In the absence of sodium, changes in pH had no major effect. By contrast, changes in Na+ concentration caused a marked conformational change that was largely pH-independent. Crystallographically determined, apparent dissociation constants indicated ∼10-fold stronger Na+ binding at pH 8 than at pH 4, consistent with substrate competition for a common ion-binding site. Projection difference maps indicated helix movements by about 2 Å in the 6-helix bundle region of MjNhaP1 that is thought to contain the ion translocation site. We propose that these movements convert the antiporter from the proton-bound, outward-open state to the Na+-bound, inward-open state. Oscillation between the two states would result in rapid Na+/H+ antiport.
The forest, savanna, and grassland biomes, and the transitions between them, are expected to undergo major changes in the future, due to global climate change. Dynamic Global Vegetation Models (DGVMs) are very useful to understand vegetation dynamics under present climate, and to predict its changes under future conditions. However, several DGVMs display high uncertainty in predicting vegetation in tropical areas. Here we perform a comparative analysis of three different DGVMs (JSBACH, LPJ-GUESS-SPITFIRE and aDGVM) with regard to their representation of the ecological mechanisms and feedbacks that determine the forest, savanna and grassland biomes, in an attempt to bridge the knowledge gap between ecology and global modelling. Model outcomes, obtained including different mechanisms, are compared to observed tree cover along a mean annual precipitation gradient in Africa. Through these comparisons, and by drawing on the large number of recent studies that have delivered new insights into the ecology of tropical ecosystems in general, and of savannas in particular, we identify two main mechanisms that need an improved representation in the DGVMs. The first mechanism includes water limitation to tree growth, and tree-grass competition for water, which are key factors in determining savanna presence in arid and semi-arid areas. The second is a grass-fire feedback, which maintains both forest and savanna occurrences in mesic areas. Grasses constitute the majority of the fuel load, and at the same time benefit from the openness of the landscape after fires, since they recover faster than trees. Additionally, these two mechanisms are better represented when the models also include tree life stages (adults and seedlings), and distinguish between fire-prone and shade-tolerant savanna trees, and fire-resistant and shade-intolerant forest trees. Including these basic elements could improve the predictive ability of the DGVMs, not only under current climate conditions but also and especially under future scenarios.
Walter Benjamins Name taucht in Kracauers fragmentarisch gebliebenem Spätwerk 'History - The Last Things before the Last' (1969) nur wenige Male auf, jedoch finden sich unter den Materialien und Vorarbeiten zu diesem Werk, die in seinem Nachlass im Deutschen Literaturarchiv in Marbach aufbewahrt werden, einige Lektürenotizen zu Benjamins Thesen "Über den Begriff der Geschichte". Ein Briefumschlag mit Karteikarten versammelt eine Reihe von Kommentaren, die es erlauben, Kracauers Blick auf diesen Text zu rekonstruieren. Dies erscheint umso interessanter, als es sich hier um die Rezeption eines sehr gut informierten zeitweiligen Weggefährten und Schicksalsgenossen handelt, der sich als Überlebender in den 1960er Jahren, etwas mehr als zwei Jahrzehnte nach der Entstehung von "Über den Begriff der Geschichte", manchen ihrer einst gemeinsamen Fragestellungen erneut zuwendet.
Karin Baumgartner diskutiert Strategien zur Bewältigung der adligen Legitimationskrise nach den preußischen Landreformen und gegenüber einem bislang unbekannten Rechtfertigungsdruck, der aus einer finanziell oftmals prekären Lage resultierte und seitens eines Bürgertums ausgeübt wird, das als produktive und staatstragende Klasse auf den historischen Schauplatz drängt. Als Gegner des Smithschen Liberalismus und vor allem der französischen Freiheitsdoktrin verteidigt der romantische Staatstheoretiker Adam Müller dabei das positive Recht als organisch gewachsene Institution, deren abrupte Veränderung zugunsten einer entfesselten frühkapitalistischen Produktivität die tradierte natürliche Balance zwischen gewerblichem und landwirtschaftlichem Sektor störe und umstürzlerische Auswirkungen nach sich ziehen könne. Müller sei der Erste, so Karin Baumgartner, der Klasse und Geschlecht aneinanderkopple und damit "Caroline Fouqué Argumente liefert, um die Legitimationskrise des Adels in ihren Romanen als männlich-weibliche Beziehungskrise zu verarbeiten." Gegen den bürgerlichen Vorwurf der Unproduktivität führe Adam Müller darüber hinaus einen "Geist" und eine "Tradition" als allein durch den Adel einzubringende ideelle Ressourcen ins Spiel, die letztlich Stabilität des Gemeinwesens garantieren könnten.
This article reviews the most recent results concerning second harmonic generation (SHG) experiments of non-phase matchable and phase matchable powder samples at high pressures and explains the pressure dependence of the intensity of the SHG signal by correlating it to the ratio between the average coherence length and the average particle size. The examples discussed here include pressure-induced structural changes in quartz, ZnO, ice VII and KIO3. It is shown that the second harmonic generation technique is a unique tool for the detection of pressure-induced structural phase transitions. It is laboratory based and allows fast measurements. It is complementary to X-ray diffraction and provides additional information about the presence of an inversion center for unknown or controversially discussed structures at high pressure.
The African species Cheiracanthium furculatum Karsch, 1879 was recognised as being introduced to Germany and is re-described and illustrated in the present study. C. tenuipes Roewer, 1961 is recognised as a junior synonym of C. africanum Lessert, 1921 (new synonymy); both subspecies of C. strasseni Strand, 1915, namely C. strasseni strasseni Strand, 1915 and C. strasseni aharonii Strand, 1915, are recognised as junior synonyms of C. mildei L. Koch, 1864 (new synonymies). Photographic images of the copulatory organs of the types of C. cretense Roewer, 1928, recently synonymised with C. mildei, are provided and discussed in the course of intraspecific variation in C. mildei. The female holotype of C. rehobothense Strand, 1915 is re-described and illustrated. Relations of C. rehobothense to other Cheiracanthium species are discussed.
Glioblastoma multiforme (GBM) is a deadly primary brain malignancy. Glioblastoma stem cells (GSC), which have the ability to self-renew and differentiate into tumor lineages, are believed to cause tumor recurrence due to their resistance to current therapies. A subset of GSCs is marked by cell surface expression of CD133, a glycosylated pentaspan transmembrane protein. The study of CD133-expressing GSCs has been limited by the relative paucity of genetic tools that specifically target them. Here, we present CD133-LV, a lentiviral vector presenting a single chain antibody against CD133 on its envelope, as a vehicle for the selective transduction of CD133-expressing GSCs. We show that CD133-LV selectively transduces CD133+ human GSCs in dose-dependent manner and that transduced cells maintain their stem-like properties. The transduction efficiency of CD133-LV is reduced by an antibody that recognizes the same epitope on CD133 as the viral envelope and by shRNA-mediated knockdown of CD133. Conversely, the rate of transduction by CD133-LV is augmented by overexpression of CD133 in primary human GBM cultures. CD133-LV selectively transduces CD133-expressing cells in intracranial human GBM xenografts in NOD.SCID mice, but spares normal mouse brain tissue, neurons derived from human embryonic stem cells and primary human astrocytes. Our findings indicate that CD133-LV represents a novel tool for the selective genetic manipulation of CD133-expressing GSCs, and can be used to answer important questions about how these cells contribute to tumor biology and therapy resistance.
The growing role of IT in real estate asset management – the appraisal process as a master sample
(2014)
"Wie so oft, war es auch in Ihrem Falle leichter, Unrecht zu tun, als dieses Unrecht wieder gutzumachen." Mit dieser bitteren Bemerkung fasste im Oktober 1957 der Dekan der Wirtschafts- und Sozialwissenschaftlichen Fakultät, der Ökonom Prof. Dr. Hans Möller, in einem Entschuldigungsschreiben an Walter Braeuer ein Rehabilitierungsverfahren zusammen, das bereits mehr als zehn Jahre zuvor im Januar 1946 gestartet war.
MTO1-deficient mouse model mirrors the human phenotype showing complex I defect and cardiomyopathy
(2014)
Recently, mutations in the mitochondrial translation optimization factor 1 gene (MTO1) were identified as causative in children with hypertrophic cardiomyopathy, lactic acidosis and respiratory chain defect. Here, we describe an MTO1-deficient mouse model generated by gene trap mutagenesis that mirrors the human phenotype remarkably well. As in patients, the most prominent signs and symptoms were cardiovascular and included bradycardia and cardiomyopathy. In addition, the mutant mice showed a marked worsening of arrhythmias during induction and reversal of anaesthesia. The detailed morphological and biochemical workup of murine hearts indicated that the myocardial damage was due to complex I deficiency and mitochondrial dysfunction. In contrast, neurological examination was largely normal in Mto1-deficient mice. A translational consequence of this mouse model may be to caution against anaesthesia-related cardiac arrhythmias which may be fatal in patients.
Der Beitrag untersucht Polyglossie als eine Form der ästhetischen Polyphonie. Damit rücken die Aspekte der Vielstimmigkeit und Multiperspektivität in den Blick, poetologische Verfahren, die wesentlich die literarische Moderne des 20. Jahrhunderts prägen. Die zivilisatorische Moderne ist gekennzeichnet durch Dialogizität und Vielstimmigkeit, Dezentralisierung und Heterogenität, Simultanität und Interferenz. Über eine Ästhetik des Polyphonen re-lektieren literarische Texte so Merkmale einer modernen Lebens- und Erfahrungswelt, was anhand von Alfred Döblins modernem Großstadtepos "Berlin Alexanderplatz" veranschaulicht wird.
Background: Evaluation of automated attenuation-based tube potential selection and its impact on image quality and radiation dose in CT (computed tomography) examinations for cancer staging.
Methods: A total of 110 (59 men, 51 women) patients underwent chest-abdomen-pelvis CT examinations; 55 using a fixed tube potential of 120 kV/current of 210 Reference mAs (using CareDose4D), and 55 using automated attenuation-based tube potential selection (CAREkV) also using a current of 210 Reference mAs. This evaluation was performed as a single-centre, observer-blinded retrospective analysis. Image quality was assessed by two readers in consensus. Attenuation, image noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) were measured or calculated for objective image evaluation. For the evaluation of radiation exposure, dose-length-product (DLP) values were compared and Size-specific dose estimates (SSDE) values were calculated.
Results: Diagnostic image quality was obtained from all patients. The median DLP (703.5 mGy · cm, range 390–2203 mGy · cm) was 7.9% lower when using the algorithm compared with the standard 120 kV protocol (median 756 mGy · cm, range 345–2267 mGy · cm). A reduction in potential to 100 kV occurred in 32 cases; therefore, these patients received significantly lower radiation exposure compared with the 120 kV protocol.
Conclusion: Automated attenuation-based tube potential selection produces good diagnostic image quality in chest-abdomen-pelvis CT and reduces the patient’s overall radiation dose by 7.9% compared to the standard 120 kV protocol.
O kognitivnim temeljima položaja modifikatora, determinatora i kvantifikatora u imenskoj sintagmi
(2014)
U središtu je pozornosti ovoga rada redoslijed pridjevnih (premodifikacijskih), determinacijskih te kvantifikacijskih sastavnica višestrukosloženih imenskih sintagmi u hrvatskom jeziku. Metodologijom kognitivne gramatike (Langacker 1987, 1991, Taylor 2002, Radden i Dirven 2007) na nekoliko se tipičnih primjera najprije objašnjavaju značenjski aspekti koji uvjetuju neutralan redoslijed njihovih sastavnica, a zatim se preispituje manja ili veća neovjerenost pojedinih konstrukcija pri promjeni redoslijeda sastavnica. Ključnim semantičko-pragmatičkim čimbenikom koji uvjetuje veću ili manju ovjerenost takvih konstrukcija, a uvjetovanu promjenom redoslijeda sastavnica, smatra se referencija odnosno ‘usidrenje’ (engl. grounding) koja se odnosi na uspostavljanje „mentalnoga kontakta” sudionika govornoga čina s referentom imenske sintagme. S obzirom na to posebna se pozornost posvećuje značenjskim razlikama između elemenata referencije – determinatora, relativnih i neodređenih apsolutnih kvantifikatora – te pridjevnih premodifikatora i određenih apsolutnih kvantifikatora (brojeva) koji to nisu.
La influencia de Marcel Proust en el pensamiento de Benjamin fue tal que llevó al filósofo berlinés a plantearse el peligro de una pérdida de la independencia intelectual de su propio pensamiento. Benjamin no solamente tradujo parte de "À la recherche du temps perdu", sino que recuperó imágenes y conceptos del novelista que incorporó a su pensamiento filosófico. Es de una importancia destacada el rol de ciertos conceptos proustianos en "Das Passagen-Werk" en donde Benjamin recupera su noción de despertar en términos políticos. Este trabajo se propone mostrar entonces las continuidades y rupturas de la lectura benjaminiana del novelista francés, poniendo especial interés en su significación política.
Acacia pendula, Weeping Myall, (family Fabaceae) is the most legislatively protected plant species in the New South Wales Hunter Valley. Under the NSW Threatened Species Conservation Act 1995 it is listed as an Endangered Population (in the Hunter Valley) and as a component of two Endangered Ecological Communities (one in the Hunter, one elsewhere in NSW); it is also listed as a Critically Endangered Ecological Community (in the Hunter Valley) on the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 and listed as threatened in three other eastern Australian States.
To ascertain the likely original distribution of stands of Acacia pendula in the Hunter Valley, this paper examines the writings of early Australian explorers, herbarium and database records, and the species habitat attributes across NSW. None of the journals examined, including those of botanist/explorer Allan Cunningham (who originally collected Acacia pendula from the Lachlan River in 1817), Thomas Mitchell or Ludwig Leichhardt, make note of the species for the Hunter Valley. Several explorers do, however, record Acacia pendula regularly (>100 times) across other parts of NSW, Queensland, and South Australia.
Historical herbarium and database records show a paucity of records from the Hunter prior to the year 2000, after which a 37-fold increase in observations since 1951 is apparent. For the first 128 years of botanical exploration (1823 to 1951), there are no validated collections or records of Acacia pendula from the Hunter Valley. The single exception is a specimen collected by Cunningham from 1825 (lodged at Kew, UK), purported to be from ‘Hunters River’, but which is morphologically different to other collections of Acacia pendula from that time. There is some uncertainty over the origins of this specimen.
Analysis of habitats supporting Acacia pendula in NSW outside of the Hunter show them to differ significantly in geological age, soil type, rainfall and elevation from those in the Hunter.
Collectively, these findings provide a strong circumstantial case that Acacia pendula was absent from the Hunter at the time of European settlement; this has important implications for the conservation and management of Hunter stands. Rather than being a threatened species in the Hunter Valley, it is postulated that Acacia pendula has been intentionally and/or accidentally introduced to the region, and may now be imposing a new and emerging threat to the endangered grassy woodlands and forests there. There is now an urgent need for genetic studies to clarify the origins of the current Hunter Valley stands, and to define the taxonomic limits of Acacia pendula and its close relatives.
The ( J, T ) = (1, 1) parity doublet in 20Ne at 11.26 MeV is a good candidate to study parity violation in nuclei. However, its energy splitting is known with insufficient accuracy for quantitative estimates of parity violating effects. To improve on this unsatisfactory situation, nuclear resonance fluorescence experiments using linearly and circularly polarized γ -ray beams were used to determine the energy difference of the parity doublet E = E(1−) − E(1+) = −3.2(±0.7)stat( +0.6 −1.2)sys keV and the ratio of their integrated cross sections I (+) s,0 /I (−) s,0 = 29(±3)stat( +14 −7 )sys. Shell-model calculations predict a parityviolating matrix element having a value in the range 0.46–0.83 eV for the parity doublet. The small energy difference of the parity doublet makes 20Ne an excellent candidate to study parity violation in nuclear excitations.

Die vorliegende Arbeit liefert ein Kurzportrait von Botrychium simplex und beschreibt zunächst die biologischen Besonderheiten und die Verbreitung in Deutschland. In einem dritten Teil wird eine demographische Studie vorgestellt und über Langzeitbeobachtungen an der aktuell einzigen deutschen Population (in der Senne, Nordrhein-Westfalen) berichtet. Wie bei allen Mondrauten keimen bei B. simplex die Sporen im Boden, und die Gametophyten entwickeln sich nur weiter, wenn sie von einem arbuskulären Mykorrhizapilz infiziert wurden; auch die Sporophyten sind mykotroph. Typisch sind ein- oder auch mehrjährige Ruheperioden, in denen bei einzelnen Pflanzen keine oberirdischen Organe gebildet werden. Als kleinwüchsige und konkurrenzschwache Art ist B. simplex auf lückige und kurzrasige Pflanzengesellschaften angewiesen. Die morphologische Variabilität der Blätter ist ungewöhnlich groß, und vor allem die Form des sterilen Abschnitts ist vielgestaltig. Von den mehreren in Nordamerika unterschiedenen Varietäten kommt neben der häufigeren var. simplex auch var. tenebrosum in Mitteleuropa vor. Botrychium simplex ist eine Art der gemäßigten bis kühl-gemäßigten Zone mit einem Areal, das Europa, Nordamerika sowie Indien und Japan einschließt. In Deutschland sind Vorkommen aus 3 Jahrhunderten und auf 12 Messtischblättern belegt. Die Funde konzentrieren sich auf das 19. Jahrhundert; aus dem 20. Jahrhundert stammen lediglich 5 Angaben.
Escherichia coli α-hemolysin (HlyA) is a pore-forming protein of 110 kDa belonging to the family of RTX toxins. A hydrophobic region between the amino acid residues 238 and 410 in the N-terminal half of HlyA has previously been suggested to form hydrophobic and/or amphipathic α-helices and has been shown to be important for hemolytic activity and pore formation in biological and artificial membranes. The structure of the HlyA transmembrane channel is, however, largely unknown. For further investigation of the channel structure, we deleted in HlyA different stretches of amino acids that could form amphipathic β-strands according to secondary structure predictions (residues 71–110, 158–167, 180–203, and 264–286). These deletions resulted in HlyA mutants with strongly reduced hemolytic activity. Lipid bilayer measurements demonstrated that HlyAΔ71–110 and HlyAΔ264–286 formed channels with much smaller single-channel conductance than wildtype HlyA, whereas their channel-forming activity was virtually as high as that of the wildtype toxin. HlyAΔ158–167 and HlyAΔ180–203 were unable to form defined channels in lipid bilayers. Calculations based on the single-channel data indicated that the channels generated by HlyAΔ71–110 and HlyAΔ264–286 had a smaller size (diameter about 1.4 to 1.8 nm) than wildtype HlyA channels (diameter about 2.0 to 2.6 nm), suggesting that in these mutants part of the channel-forming domain was removed. Osmotic protection experiments with erythrocytes confirmed that HlyA, HlyAΔ71–110, and HlyAΔ264–286 form defined transmembrane pores and suggested channel diameters that largely agreed with those estimated from the single-channel data. Taken together, these results suggest that the channel-forming domain of HlyA might contain β-strands, possibly in addition to α-helical structures.
Zu den exzellenten Frankfurter Neurowissenschaftlern des 20. Jahrhunderts zählt Kurt Goldstein. Er durchlief die harte Schule von Ludwig Edinger. Bekannt wurde er jedoch durch einen eigenständigen Ansatz, der mit dem Schlagwort ganzheitliche Neurologie charakterisiert werden kann. Er wandte sich gegen die Auffassung, »Funktionen« im Gehirn exakt lokalisieren zu können, ohne den lokalisatorischen Ansatz vollständig zu verwerfen. Besondere Aufmerksamkeit schenkte er den Kompensationsreaktionen des Gehirns und des »ganzen« Menschen. » […] he never forgot that he addressed an individual, not a brain«, brachte es sein Schüler Walther Riese auf den Punkt.
Jetzt, nach Beendigung vieler Jahre der Lehre und Forschung an der Goethe-Universität, kann ich diese Zeit mit einem Abstand überdenken. Der Freiraum für solch nicht zweckgerichtetes Verhalten ist während der praktischen Tätigkeit an der Universität äußerst gering und muss hart erkämpft werden, wie jedes Stück Freiheit. Rückblickend sehe ich, dass der Wunsch, über das Detailwissen hinaus ganzheitliche Zusammenhänge zu betrachten und über die eigene Fachgrenze hinauszugehen, meinen Weg geprägt hat.
Wer nicht nur die Tag-, sondern auch die Nachtseite des menschlichen Seelenlebens beschreiben möchte, so könnte die Konsequenz aus dem Vergleich der beiden Texte Hoffmanns lauten, muss sich die, der Zigeunerin zugeschriebene, "schmutzige" Kraft der Natur zu eigen machen. Umgekehrt resultiert daraus, dass sich in dieser schmutzigen Kraft, über welche die Zigeunerin verfügt, Potenzial von allerhöchstem literarischen Adel verbirgt. Zigeunerromantik eben.
[...] Halten wir [...] als Arbeitshypothese fest, dass Jean Paul in seinem zweiten bürgerlichen Roman nach dem "Siebenkäs" einerseits den Gedanken der psychischen Doppelgängerschaft fortschreibt, ihm aber andererseits über die Zwillingsmetapher eine neue, hereditäre und generative Dimension verleiht.
Auch wenn das auf den ersten Blick kontraintuitiv erscheint, steht diese Veränderung, wie sich herausstellen wird, für eine größere und größer werdende Unähnlichkeit zwischen den beiden Helden. Der gleitende Wechsel der Metaphern markiert also einen sich schon im "Siebenkäs" abzeichnenden, in den "Flegeljahren" jedoch verstärkt fortgesetzten Entfremdungsprozess der für
die bürgerlichen Romane konstitutiven Doppel-Protagonisten.
[...] [Hoffmann] ist es im Sandmann [...] darum zu tun, beide Lesarten, die des Übernatürlichen/Wunderbaren auf der einen Seite und des Natürlichen, in diesem Falle: des dezidiert Psychologischen, auf der anderen, in der Schwebe zu halten. [...] er verfolgt [...] eine Strategie der unsinnlichen Ähnlichkeit, dergestalt dass das Wunderbare mittels einer metaphysisch angereicherten Psychologie als allegorisch lesbar wird.
Das Thema des Monologs ist das Schreiben und Sprechen als
"närrische Sache". Ich beginne meine Lektüre, indem ich den Begriff wörtlich nehme: Ein Narr ist, in der Psychologie der Zeit, jemand, der an Melancholie leidet, dessen Verstand bzw. Vernunft jedoch nicht vollständig, sondern nur teilweise angegriffen ist. [...] Die Diagnose der Narrheit gilt auch [...] für denjenigen, der sich in Novalis' Augen der Sprache zuwendet. Auch er wird zum Narren oder Partialwahnsinnigen, der sowohl vernünftig als auch ganz und gar unvernünftig sprechen kann. Die Krankheit liegt aber, und das stellt eine Differenz gegenüber der Psychologie der Zeit dar, nicht im Sprechenden, zumindest nicht in ihm allein, sondern in der Sprache. Sie selbst ist es, welche die "närrische Sache" ausmacht.
The title solvated salt, C29H41N2+·Br-·2CH2Cl2 was obtained from the reaction of the Arduengo-type carbene 1,3-bis(2,6-diisopropylphenyl)-1,3-dihydro-4,5-dimethyl-2H-imidazol-2-ylidene with Si2Br6 in dichloromethane. The complete cation is generated by a crystallographic mirror plane and the dihedral angle between the five-membered ring and the benzene ring is 89.8 (6)°; the dihedral angle between the benzene rings is 40.7 (2)°. The anion also lies on the mirror plane and both dichloromethane molecules are disordered across the mirror plane over two equally occupied orientations. In the crystal, the cations are linked to the anions via C-H...Br hydrogen bonds.
Background: Birch pollen-allergic subjects produce polyclonal cross-reactive IgE antibodies that mediate pollen-associated food allergies. The major allergen Bet v 1 and its homologs in plant foods bind IgE in their native protein conformation. Information on location, number and clinical relevance of IgE epitopes is limited. We addressed the use of an allergen-related protein model to identify amino acids critical for IgE binding of PR-10 allergens.
Method: Norcoclaurine synthase (NCS) from meadow rue is structurally homologous to Bet v 1 but does not bind Bet v 1-reactive IgE. NCS was used as the template for epitope grafting. NCS variants were tested with sera from 70 birch pollen allergic subjects and with monoclonal antibody BV16 reported to compete with IgE binding to Bet v 1.
Results: We generated an NCS variant (Δ29NCSN57/I58E/D60N/V63P/D68K) harboring an IgE epitope of Bet v 1. Bet v 1-type protein folding of the NCS variant was evaluated by 1H-15N-HSQC NMR spectroscopy. BV16 bound the NCS variant and 71% (50/70 sera) of our study population showed significant IgE binding. We observed IgE and BV16 cross-reactivity to the epitope presented by the NCS variant in a subgroup of Bet v 1-related allergens. Moreover BV16 blocked IgE binding to the NCS variant. Antibody cross-reactivity depended on a defined orientation of amino acids within the Bet v 1-type conformation.
Conclusion: Our system allows the evaluation of patient-specific epitope profiles and will facilitate both the identification of clinically relevant epitopes as biomarkers and the monitoring of therapeutic outcomes to improve diagnosis, prognosis, and therapy of allergies caused by PR-10 proteins.
Voraussetzung für argumentative Rede ist zum einen ihre Kohärenz; zum andern das Gelingen ihrer Referenz. Die Texte, die der poeta doctus Musil unter dem Titel 'Drei Frauen' versammelt hat, gehören nicht der argumentativen Rede an. Sie sind erzählender Natur. Dennoch problematisieren sie, wie wir vertreten möchten, die Voraussetzungen argumentativer Rede. Während 'Die Portugiesin' mit der Deixis (wie andernorts schon vorgeführt) den Weltbezug zu ihrem Thema macht, handeln 'Grigia' und 'Tonka' von der Verknüpfung elementarer Sätze zu Texten. In beiden Erzählungen werden die Konjunktionen zum Problem; das aber aus signifikant verschiedenen Gründen. Aus ähnlich verschiedenen Gründen werden in den fiktionalen Welten, die uns in 'Grigia' und 'Tonka' begegnen, Zusammenhänge zum Problem. Ein Textvergleich tut not; er führt auf die Bezüge, die wir soeben angedeutet haben.

Hereditary angioedema (HAE) is a disease which is associated with random and often unpredictable attacks of painful swelling typically affecting the extremities, bowel mucosa, genitals, face and upper airway. Attacks are associated with significant functional impairment, decreased Health Related Quality of Life, and mortality in the case of laryngeal attacks. Caring for patients with HAE can be challenging due to the complexity of this disease. The care of patients with HAE in Canada is neither optimal nor uniform across the country. It lags behind other countries where there are more organized models for HAE management, and where additional therapeutic options are licensed and available for use. The objective of this guideline is to provide graded recommendations for the management of patients in Canada with HAE. This includes the treatment of attacks, short-term prophylaxis, long-term prophylaxis, and recommendations for self-administration, individualized therapy, quality of life, and comprehensive care. It is anticipated that by providing this guideline to caregivers, policy makers, patients and their advocates, that there will be an improved understanding of the current recommendations regarding management of HAE and the factors that need to be considered when choosing therapies and treatment plans for individual patients. The primary target users of this guideline are healthcare providers who are managing patients with HAE. Other healthcare providers who may use this guideline are emergency physicians, gastroenterologists, dentists and otolaryngologists, who will encounter patients with HAE and need to be aware of this condition. Hospital administrators, insurers and policy makers may also find this guideline helpful.
Research in the field of Digital Humanities, also known as Humanities Computing, has seen a steady increase over the past years. Situated at the intersection of computing science and the humanities, present efforts focus on making resources such as texts, images, musical pieces and other semiotic artifacts digitally available, searchable and analysable. To this end, computational tools enabling textual search, visual analytics, data mining, statistics and natural language processing are harnessed to support the humanities researcher. The processing of large data sets with appropriate software opens up novel and fruitful approaches to questions in the traditional humanities. This report summarizes the Dagstuhl seminar 14301 on “Computational Humanities - bridging the gap between Computer Science and Digital Humanities”.

BACKGROUND: Recent findings support the idea that interleukin (IL)-22 serum levels are related to disease severity in end-stage liver disease. Existing scoring systems--Model for End-Stage Liver Disease (MELD), Survival Outcomes Following Liver Transplantation (SOFT) and Pre-allocation-SOFT (P-SOFT)--are well-established in appraising survival rates with or without liver transplantation. We tested the hypothesis that IL-22 serum levels at transplantation date correlate with survival and potentially have value as a predictive factor for survival.
MATERIAL AND METHODS: MELD, SOFT, and P-SOFT scores were calculated to estimate post-transplantation survival. Serum levels of IL-22, IL-6, IL-10, C-reactive protein (CRP), and procalcitonin (PCT) were collected prior to transplantation in 41 patients. Outcomes were assessed at 3 months, 1 year, and 3 years after transplantation.
RESULTS: IL-22 significantly correlated with MELD, P-SOFT, and SOFT scores (Rs 0.35, 0.63, 0.56 respectively, p<0.05) and with the discrimination in post-transplantation survival. IL-6 showed a heterogeneous pattern (Rs 0.40, 0.63, 0.57, respectively, p<0.05); CRP and PCT did not correlate. We therefore added IL-22 serum values to existing scoring systems in a generalized linear model (GLM), resulting in a significantly improved outcome prediction in 58% of the cases for both the P-SOFT (p<0.01) and SOFT scores (p<0.001).
CONCLUSIONS: Further studies are needed to address the concept that IL-22 serum values at the time of transplantation provide valuable information about survival rates following orthotopic liver transplantation.
Die folgenden Überlegungen behandeln Phänomene der Temporalität und Zeitchoreographie in Walter Benjamins Prosamix 'Berliner Kindheit um neunzehnhundert'. Es gilt darüber nachzudenken, inwieweit es sich hierbei um ein ästhetisch induziertes Zeitarrangement handelt, von dem sich sagen ließe, dass in Augenblicken dieser faszinierenden Erinnerungsbilder die Zeit poetologisch konzeptionell geordnet, doch nicht instrumentell hierarchisiert wird. Sollen also Zeitphänomene im ästhetischen Modus betrachtet werden, so wird es unverzichtbar sein, sich der ästhetisch realisierten Zeitvarianten so zu versichern, dass eine minimale Zeitphilosophie formulierbar ist, die mehr besagt als eine rein systematisierende Zeitkasuistik. Von einer mikrologischen Zeitrettung könnte dann gesprochen werden, wenn unter dem Modus der Erinnerung dieser autobiographischen Sequenzen nicht allein Aspekte der Verräumlichung und Topographie verstanden werden, sondern stattdessen auch jene Zeitreserven in den Blick genommen werden, die besonders im Modus der Selbstwahrnehmung beim Erinnern hervorgebracht werden. Ich möchte die These vertreten, dass Benjamin als Zeitsammler, Zeitbewahrer und als uchronischer Zeitphysiognomiker auf der Grundlage einer tendenziellen Stillstellung von Zeit in diesen prosaischen Bildsequenzen gegenläufig geradezu multiple und dynamisierte Zeitphänomene und Zeiterfahrungen hervorbringt. Da diese an einen bestimmten rekursiven Wahrnehmungsmodus gebunden sind, werden zunächst Phänomene dieses Modus behandelt, um anschließend damit einhergehende Typen ästhetischer Eigenzeiten zu benennen und diese im Zusammenhang mit einer strukturierenden Logik der uchronischen Zeitlichkeit in der 'Berliner Kindheit' zu denken.
Tema je našega rada položaj zamjeničkoga pridjeva sam uz naglašeni oblik povratne zamjenice (sebe) unutar konstrukcija s pravim povratnim glagolima. U tim konstrukcijama zamjenički pridjev sam može biti u akuzativu ili u nominativu (hvalim sam sebe / hvalim samog sebe). Poznato je svojstvo zamjeničkoga pridjeva sam da u pojačajnome značenju najčešće slijedi iza lične zamjenice, ali prethodi imenicama (On sam to radi. / Sama Marija to radi.). Cilj je ovoga istraživanja utvrditi koji mu je neobilježeni položaj uz povratnu zamjenicu te ponaša li se drukčije s obzirom na red riječ kad je u nominativnome ili u akuzativnome obliku.
U redu riječi prijedlozi imaju relativno stalno mjesto po kojemu su i nazvani – predlažu se ispred riječi na koju se odnose. U gramatikama se još spominje i postpozicija, kad prijedlozi dolaze iza riječi na koju se odnose (svemu unatoč...). U ovom radu prijedlozi se ne promatraju na morfološkoj razini, dakle na razini jedne riječi, nego se promatraju kao funkcionalna skupina koja uključuje i višerječne prijedložne izraze. Analizom su obuhvaćene i sveze riječi, odnosno koligacije temeljene na gramatičkoj uvjetovanosti sastavnica, a koje tvore jednu značenjsku cjelinu. Ta dva metodološka pomaka u percepciji prijedloga i u percepciji riječi pokazuju da se prijedlog može naći i u drugim pozicijama te se u radu analizira gdje se sve u rečenici mogu naći prijedlozi.
La primera parte del "Guzmán de Alfarache" nace justo cuando muere el siglo XVI, en 1599. En realidad, estaba terminada al cabo del año 1597, aunque no será hasta el último de la centuria cuando se ponga a la venta. Como dice uno de los editores modernos, José María Micó, tardó más en imprimirse que en hacerse famosa, porque bien pronto se multiplican las ediciones legales e ilegales del texto. En 1600, Alemán prepara una versión corregida de esa primera parte, cuando las aventuras del Pícaro, como se le llamará por antonomasia, podían leerse ya en Media Europa y en el Nuevo Mundo, según puso de manifiesto Maxime Chevalier, siguiendo la estela de los libros del Conquistador: un tal Juan de Ugarte, que llega en una nave española a Vera Cruz, es registrado por los comisarios de la Inquisición, y reconoce que llevó durante el viaje, "para divertirse", la "Arcadia" de Lope de Vega y el "Guzmán de Alfarache".
Silometopus ambiguus (O. Pickard-Cambridge, 1905) is a species occurring in coastal habitats from northeastern to western Europe. S. curtus (Simon, 1881), occurring in southern France and north-eastern Spain, was for a long time mixed up with S. ambiguus, even though corrections have been published very early and several times. This contribution summarizes publications on this topic, discusses doubtful records of both species and proposes corrections for the World Spider Catalog; and thus tries to avoid repetitions of the mistake in the future.
ALMOST 20% OF THE GERMAN POPULATION CURRENTLY HOLDS A CONSUMER LOAN. DESPITE ITS OBVIOUS IMPORTANCE FOR A PRIVATE HOUSEHOLD’S BALANCE SHEET, WE KNOW SURPRISINGLY LITTLE ABOUT IT. ONE PURPOSE OF THIS STUDY IS TO GIVE AN OVERVIEW OF THE GERMAN CONSUMER/INSTALLMENT LOAN MARKET. WE COMPARED FIVE WIDELY ACCEPTED DATA SOURCES AND FOUND DIFFERENCES IN THE LOAN PARTICIPATION RATE, EVEN ON AN AGGREGATED NATIONWIDE LEVEL. IN A SECOND STEP, WE TRY TO FIND REASONS FOR EXTRAORDINARY HIGH GROWTH RATES AMONG SENIORS’ DEBT PARTICIPATION RATES.
Sanctions placed upon airlines and other operators transporting persons without the required paperwork are called ‘carrier sanctions’. They constitute a key example of how border control mechanisms are currently being outsourced, privatized, delegated, and moved from the border itself to new physical locations. These practices can lead to a phenomenon referred to in this paper as ‘hidden coercion’. This paper argues that, while hidden coercion is commonplace in the reality of migration policy in most states, it is so far neglected in theoretical discussions of state coercion. Moreover, the discussion of carrier sanctions demonstrates that this neglect is problematic, since hidden coercion is not justifiable even within a framework that legitimizes state border coercion.
We review recent results on J/ψ production measured by the ALICE collaboration at the LHC. For pp collisions at √s = 7 TeV yields and spectra of inclusive and prompt J/ψ, as well as results on their polarization and the charged particle multiplicity dependence of yields are presented. Measurements of the nuclear modification factor RAA of inclusive J/ψ at mid-(|y| < 0.9) and forward-rapidities (2.5 < y < 4), covering the range to pt = 0, for centrality selected Pb-Pb collisions are discussed. Also, first results on the J/ψυ2 at forward-rapidities are shown.
Der Aufsatz untersucht das syntaktische Verhalten nicht-satzförmiger Adverbialia im Deutschen und im brasilianischen Portugiesisch in vergleichender Perspektive. Behandelt werden Adverbialia aus sechs Klassen, deren semantische Funktionen von der Sachverhaltsbeschreibung bis zur Beschreibung von Handlungsabsichten des Sprechers reichen. Insgesamt zeigen sich große Ähnlichkeiten zwischen den Vergleichssprachen. Im Deutschen scheint eine etwas stärkere Tendenz zu bestehen, Adverbialia syntaktisch zu integrieren, während es im Portugiesischen mehr Möglichkeiten gibt, sie desintegriert zu verwenden.
Background: The current taxonomy of the African giraffe (Giraffa camelopardalis) is primarily based on pelage pattern and geographic distribution, and nine subspecies are currently recognized. Although genetic studies have been conducted, their resolution is low, mainly due to limited sampling. Detailed knowledge about the genetic variation and phylogeography of the South African giraffe (G. c. giraffa) and the Angolan giraffe (G. c. angolensis) is lacking. We investigate genetic variation among giraffe matrilines by increased sampling, with a focus on giraffe key areas in southern Africa.
Results: The 1,562 nucleotides long mitochondrial DNA dataset (cytochrome b and partial control region) comprises 138 parsimony informative sites among 161 giraffe individuals from eight populations. We additionally included two okapis as an outgroup. The analyses of the maternally inherited sequences reveal a deep divergence between northern and southern giraffe populations in Africa, and a general pattern of distinct matrilineal clades corresponding to their geographic distribution. Divergence time estimates among giraffe populations place the deepest splits at several hundred thousand years ago.
Conclusions: Our increased sampling in southern Africa suggests that the distribution ranges of the Angolan and South African giraffe need to be redefined. Knowledge about the phylogeography and genetic variation of these two maternal lineages is crucial for the development of appropriate management strategies.
Objective: The objective of this study was to describe and analyze the effects of depression on health care utilization and costs in a sample of multimorbid elderly patients.
Method: This cross-sectional analysis used data of a prospective cohort study, consisting of 1,050 randomly selected multimorbid primary care patients aged 65 to 85 years. Depression was defined as a score of six points or more on the Geriatric Depression Scale (GDS-15). Subjects passed a geriatric assessment, including a questionnaire for health care utilization. The impact of depression on health care costs was analyzed using multiple linear regression models. A societal perspective was adopted.
Results: Prevalence of depression was 10.7%. Mean total costs per six-month period were €8,144 (95% CI: €6,199-€10,090) in patients with depression as compared to €3,137 (95% CI: €2,735-€3,538; p<0.001) in patients without depression. The positive association between depression and total costs persisted after controlling for socio-economic variables, functional status and level of multimorbidity. In particular, multiple regression analyses showed a significant positive association between depression and pharmaceutical costs.
Conclusion: Among multimorbid elderly patients, depression was associated with significantly higher health care utilization and costs. The effect of depression on costs was even greater than reported by previous studies conducted in less morbid patients.
Families are central to the social and emotional development of youth, and most families engage in musical activities together, such as listening to music or talking about their favorite songs. However, empirical evidence of the positive effects of musical family rituals on social cohesion and emotional well-being is scarce. Furthermore, the role of culture in the shaping of musical family rituals and their psychological benefits has been neglected entirely. This paper investigates musical rituals in families and in peer groups (as an important secondary socialization context) in two traditional/collectivistic and two secular/individualistic cultures, and across two developmental stages (adolescence vs. young adulthood). Based on cross-sectional data from 760 young people in Kenya, the Philippines, New Zealand, and Germany, our study revealed that across cultures music listening in families and in peer groups contributes to family and peer cohesion, respectively. Furthermore, the direct contribution of music in peer groups on well-being appears across cultural contexts, whereas musical family rituals affect emotional well-being in more traditional/collectivistic contexts. Developmental analyses show that musical family rituals are consistently and strongly related to family cohesion across developmental stages, whereas musical rituals in peer groups appear more dependent on the developmental stage (in interaction with culture). Contributing to developmental as well as cross-cultural psychology, this research elucidated musical rituals and their positive effects on the emotional and social development of young people across cultures. The implications for future research and family interventions are discussed.
Der vorliegende Beitrag fokussiert die produktive Rezeption und die kreativ-ästhethische Remodulation literarischen und kulturellen Materials in Lewalds "Italienischem Bilderbuch". Dem Vorhaben liegt die Annahme zugrunde, dass die Reiseschilderung zwar wesentlich durch ein tradierten Vorbildern verhaftetes epigonales Erzählen geprägt ist, dieses jedoch wiederholt an einzelnen Stellen im Bewusstsein literarischer Autonomie zu konterkarieren sucht. Im Rückgriff auf Manfred Pfisters "Systematik zur Intertextualität im Reisebericht" (1993) lässt sich Lewalds Reiseprosa zum einen als Ausdruck einer huldigenden Intertextualität beschreiben, der folgendes erzählerische Programm zugrunde liegt: Lewald bereist die Stationen der etablierten Bildungsreise und ordnet ihren Text gemäß dieser chronologischen Strukturprinzipien. Durch die Aktualisierung tradierter Topoi der Italiendichtung sowie durch das Anzitieren von gattungsprägenden Texten und Diskurselementen exponiert der Text seinen Status als epigonales Werk. Zum anderen lassen ausgewählte Einzelstellen Ansätze einer dialogischen Intertextualität erkennen. Die rezipierten Textzeugen werden hier am selbst Wahrgenommenen gemessen, hinterfragt und gegebenenfalls auch korrigiert. [...] Anhand von fünf paradigmatischen Textstellen sollen formale Gestaltung und Funktion dieses intertextuellen Rekursspiels ästhetisch bestimmt und kontextuell plausibilisiert werden. Referenzen auf einzelne Autoren (Goethe, von Platen, Byron) sollen dabei ebenso untersucht werden wie Stoff- und Gattungsbezüge (Mythos, Märchen und Legende).
Resveratrol shows beneficial effects in inflammation-based diseases like cancer, cardiovascular and chronic inflammatory diseases. Therefore, the molecular mechanisms of the anti-inflammatory resveratrol effects deserve more attention. In human epithelial DLD-1 and monocytic Mono Mac 6 cells resveratrol decreased the expression of iNOS, IL-8 and TNF-α by reducing mRNA stability without inhibition of the promoter activity. Shown by pharmacological and siRNA-mediated inhibition, the observed effects are SIRT1-independent. Target-fishing and drug responsive target stability experiments showed selective binding of resveratrol to the RNA-binding protein KSRP, a central post-transcriptional regulator of pro-inflammatory gene expression. Knockdown of KSRP expression prevented resveratrol-induced mRNA destabilization in human and murine cells. Resveratrol did not change KSRP expression, but immunoprecipitation experiments indicated that resveratrol reduces the p38 MAPK-related inhibitory KSRP threonine phosphorylation, without blocking p38 MAPK activation or activity. Mutation of the p38 MAPK target site in KSRP blocked the resveratrol effect on pro-inflammatory gene expression. In addition, resveratrol incubation enhanced KSRP-exosome interaction, which is important for mRNA degradation. Finally, resveratrol incubation enhanced its intra-cellular binding to the IL-8, iNOS and TNF-α mRNA. Therefore, modulation of KSRP mRNA binding activity and, thereby, enhancement of mRNA degradation seems to be the common denominator of many anti-inflammatory effects of resveratrol.
Epiphytische Moose in Nordrhein-Westfalen : häufige Arten und Einwanderung atlantischer Arten
(2014)
In Mitteleuropa sind die klassischen Epiphyten unter den Moosen und Flechten zu finden. In diesem Pflanzenportrait werden einige häufigere und einfach zu erkennende epiphytische Moose vorgestellt. Man kann sie in vielen Teilen Mitteleuropas finden, teilweise auch im Siedlungsbereich und hier besonders auf Friedhöfen und in Parks. Atlantische Arten, die sich seit einigen Jahren in Nordrhein-Westfalen ausbreiten, können einen Anreiz geben, sich näher mit epiphytischen Moosen zu beschäftigen. Von diesen werden das Hübsche Goldhaarmoos (Orthotrichum pulchellum, Moos des Jahres 2008) und das Einseitswendige Verstecktfruchtmoos (Cryphaea heteromalla) ausführlicher besprochen.
In Nordrhein-Westfalen wachsen mehrere kleinblütige Arten der Gattung Geranium (Storchschnabel). Die meisten sind zumindest im blühenden Zustand schon von Anfängern zu erkennen. Dieses Porträt richtet sich aber auch an Fortgeschrittene: Der wenig bekannte Glattfrüchtige Storchschnabel (G. aequale), der dem Weichen Storchschnabel (G. molle) sehr ähnelt und in den meisten Bestimmungsbüchern und Floren fehlt, wird ausführlich besprochen. In dieser Arbeit werden die kleinblütigen Geranium-Arten zur Blütezeit mit zahlreichen Fotos vorgestellt, wobei sowohl Blüten-, Frucht- und vegetative Merkmale berücksichtigt werden.
