Das Ziel dieses Beitrags besteht darin, am Beispiel der türkischen Germanistikstudenten an der Ege Universität die Merkmale und Entwicklung der pragmatisch-diskursiven Fähigkeit als eine Teilkompetenz der fremdsprachlichen Gesprächskompetenz zu untersuchen. Die Arbeit gliedert sich in zwei Abschnitte: Der erste Teil befasst sich mit der ausführlichen Beschreibung der Gesprächskompetenz als fremdsprachliche Kompetenz im Deutschen als Fremdsprache, der Bewertung der fremdsprachlichen Gesprächskompetenz als sprachproduktive Leistung und der Vorstellung von Subkategorien der pragmatisch-diskursiven Fähigkeit anhand der Beispiele aus dem Arbeitskorpus. Im zweiten Teil wird das Untersuchungsdesign und die Analyseergebnisse ausführlich dargestellt.
Are stereotypes possible pillars supporting the learning of a foreign language or are they possible sources of intercultural misunderstandings? In most coursebooks, intercultural materials are embedded in teaching units. The understanding of others is closely related to the understanding of someone's own culture as well as the target culture. Only when someone is aware of the own culture, then the target culture can be understood. In foreign language learning, it plays an important role, so that the knowledge of language structures alone is not enough to use the language successfully. At the same time, it requires cultural knowledge of the target language culture. This study focuses on the effects of culture-based fossilized prejudices on foreign language learning and to show the quantity of these stereotypes in given coursebooks. A coursebook analysis reveals to what extent stereotypes can be found in the respective GFL and TFL coursebooks. A compile of given stereotypes create an overall picture of foreign cultures. To what extent this overall picture reflects the reality has been handled at the end of this study
Her ne kadar Almanya politikası çeşitli fikirlerde de olsa; Almanya, tarihinde her zaman göç alan bir devlet olmuştur ve göçmenlere Almanca öğretimi konusunda oldukça köklü bir geçmişe, engin tecrübelere sahiptir. 60'lı yılların başlangıcında göçmenlere dil öğretimini gerekli görmeyen bu ülke 'dilsizliğin' getirdiği sosyal, siyasal ve ekonomik sorunlar sonrasında başarılı bir entegrasyon süreci için göçmenlere Alman dilinin öğretilmesinin gerekliliğini anlamış ve bu konuda çeşitli modeller denemiştir. Bu araştırmanın amacı; Almancanın ikinci dil olarak öğretimi alanındaki kuram ve modellerin, Türkçenin ikinci dil olarak öğretimine uyarlanabilirliğini göstermek ve Almanya'nın bu alandaki tecrübelerinden ikinci dil olarak Türkçe öğretimi alanında yararlanmaktır. Bu nedenle öncelikle 'yabancı dil' ve 'ikinci dil' kavramlarını birbirinden ayıran faktörler üzerinde durulacak ve böylece 'ikinci dil olarak Türkçe' kuramı incelenecektir. Sonrasında yine ikinci dil olarak Almanca öğretimi alanından çeşitli göçmen öğrenci tipleri ve bunlara Almanca öğretimi modelleri ortaya konacak, 'ikinci dil olarak Türkçe' kuramında karşılaşılacak öğrenci kavramının çeşitliliği değerlendirilecektir. Bu noktada okul çağında olan, okullara yatay geçiş yapması gereken ancak henüz Latin alfabesini bilmeyen, kurum olarak 'okul' kavramıyla hiç tanışmamış ve güncel Türkçenin dışında eğitim Türkçesi öğrenmesi gereken gençler üzerinde durulacaktır; çünkü toplumun birliği, bütünlüğü ve geleceği açısından özellikle bu gençlerin kazanılması büyük önem taşımaktadır. Aynı şekilde yetişkinlere Almanca öğretme modelleri tanıtılacak ve bu deneyimlerden 'ikinci dil olarak Türkçe' kuramı ve entegrasyon sürecinde nasıl yararlanılabileceği tartışılacaktır.
Bu araştırmada, 2016 yılında U. Ü. bilimsel araştırma projelerini destekleme birimi (BAP) desteğiyle başlatılan bir proje kapsamında yapılan yabancı dil öğretiminde dijital oyunlar ve oyunlaştırılmış uygulamalar geliştirme çalışmaları ele alınmıştır. Proje sürecinde yapılan alanyazın taraması ve öğretmenlerle yapılan anket çalışması sonucunda yabancı dil öğrenimi ve öğretimi süreçlerinde 3B dijital oyunların yeterince kullanılmadığı ve öğretmenlerin dijital oyun kullanma ve geliştirme konusunda yeterli kuramsal ve uygulamalı bilgiye sahip olmadıkları belirlenmiştir. Bu sonuç dikkate alınarak yapılan bu çalışmanın üçüncü bölümünde öğretmenlere ve materyal geliştiricilere yol göstermek amacıyla dijital oyun geliştirme süreci aşama aşama somut örneklerle ortaya konmuş, bu süreçte kullanılabilecek, materyal geliştirme araçları ayrıntılı olarak tanıtılmıştır. Söz konusu proje süreçlerinde elde edilen ve bu çalışmada ortaya konan bilgilerin yabancı dil öğretiminde dijital oyunların yaygınlaşmasına ve yabancı dil öğretmenlerinin kendi dersleri için dijital oyun materyallerini geliştirmelerine katkı sağlanması hedeflenmektedir.
Die Analyse und Bewertung der Sprachlernspiele in dem Lehrwerk 'MOMENT MAL 1' und 'MOMENT MAL 2'
(2018)
Das soziale und interaktive Lernen steht im Vordergrund des gesamten Lernprozesses. Auch der Erwerb einer Fremdsprache, egal in welchem Alter, verlangt soziale und interaktive Lernprozesse. Sprachlernspiele übernehmen in diesem Lernprozess eine wichtige Rolle. Diese Sprachlernspiele werden in dem kommunikativen, sowie interkulturellen Ansatz und in alternativen Methoden als Unterrichtsmaterial in den Lehrwerken benutzt. Obwohl Sprachlernspiele schon Mitte der 70er Jahre des zwanzigsten Jahrhunderts in kommunikativ orientierten Methoden ihren Höchstpunkt erreicht haben, ist das Interesse an ihrem Einsatz im Fremdsprachenunterricht bis heutzutage geblieben. Ziel dieser Studie ist, die Sprachlernspiele in den, im deutschen Sprachunterricht verwendeten Lehrwerk "Moment Mal 1" und "Moment Mal 2" zu analysieren, sie nach ihren Eigenschaften und Sprachfertigkeiten zu klassifizieren und die Bedeutung des Spielfaktors im Fremdsprachenlernen hervorzuheben. Diesbezüglich ist eine generelle Definition des Spiels behandelt und seine Eigenschaften, die zur Klassifikation der Sprachlernspiele einen Beitrag geleistet haben, hervorgehoben worden. Außerdem ist der Stellenwert der Sprachlernspiele im Fremdsprachenunterricht erforscht worden. In dieser Studie wurde die Lehrwerkanalyse als Methode verwendet. Die Sprachlernspiele in dem, im Deutschunterricht benutzten Lehrwerk "Moment Mal 1" und "Moment Mal 2" wurden nach dieser Methode analysiert. Von der allgemeinen Spieldefinition und den Zielen des Fremdsprachenunterrichts ausgehend wurden die Sprachlernspiele in diesem Lehrwerk sowohl nach ihren Eigenschaften, als auch bezüglich der Weiterförderung der Sprachfertigkeiten klassifiziert. Außerdem wurden die Sprachlernspiele aus diesem Lehrwerk in den Anadolu-Gymnasien, wo Deutsch als erste Fremdsprache gelehrt wird, ausgeübt.
Eine Studie zur fehleranalytischen Kompetenz der Studierenden in der Deutschlehrendenausbildung
(2018)
Die Fehleranalyse gilt seit langem als eine wertvolle Hilfe beim Fremdsprachenunterricht, weil sowohl Lernende als auch Lehrende dadurch wichtige Informationen über den Spracherwerbsprozess bekommen können. Auch die vorliegende Arbeit beabsichtigt mit Hilfe der Fehleranalyse zu Erkenntnissen über die fehleranalytische Kompetenz der künftigen Deutschlehrer zu gelangen. Ausgangspunkt dieser Studie war die Frage, ob es eine direkte Verbindung zwischen dem Sprachniveau und der fehleranalytischen Kompetenz der Studierenden gebe. An der Untersuchung haben 37 Studierenden der Gazi Universität teilgenommen, von denen sieben Rückkehrende aus Deutschland waren und über gute Sprachkenntnisse verfügten. Alle Probanden befanden sich im sechsten Semester und hatten sich im Rahmen der angewandten Linguistik ein semesterlang mit der Fehleranalyse befasst. Den Probanden wurden zwei Texte vorgelegt, deren Fehler sie identifizieren und anhand eines Rasters klassifizieren mussten. Es hat sich herausgestellt, dass bei der Fehleridentifizierung die Fremdsprachenkenntnisse ein entscheidender Faktor waren. Bei der Fehlerklassifizierung dagegen, schienen die Fremdsprachenkenntnisse eher eine untergeordnete Rolle zu spielen.
Im Bereich des Deutschen als Fremdsprache bietet etwa das Goethe-Institut Prüfungen auf allen Niveaus (A1-C2) an und entwickelt entsprechende Vorbereitungsmaterialien. Dazu gehören neben Modellprüfungen auch Wortlisten A1, A2 und B1 (vgl. z. B. Goethe-Institut 2016). Zur Arbeit mit den Wortlisten im DaF-Unterricht liegen nach Auskunft des Informationszentrums für Fremdsprachenforschung der Philipps-Universität Marburg vom 01.12.2017 weder wissenschaftliche Untersuchungen noch Praxisberichte vor. Mit der vorliegenden Arbeit soll versucht werden, zum Beheben dieses Desiderats beizutragen. Der Untersuchungsfokus liegt dabei auf den Erfahrungen der DaF-Studierenden mit dem Einsatz der Wortliste im Unterricht sowie ihren persönlichen Speicherstrategien beim Vokabellernen.
Die Anzahl der Werke zum Thema Antikriegsliteratur, vor allem im Zusammenhang mit dem Ersten Weltkrieg, ist im literarischen Bereich reichlich vorhanden. Die deutsche Literatur bietet durch ihre umfangreiche Anzahl Möglichkeiten diese Werke zu untersuchen. Die Darstellung des Krieges in dem Roman "Im Westen nichts Neues" ist deshalb bemerkenswert, weil es viele Beispiele zum Thema Kriegstrauma enthält. Wie wird Kriegstrauma im Roman "Im Westen nichts Neues" in der Gegenwartsliteratur geschildert bzw. thematisiert? Um diese Frage zu beantworten, soll das Motiv, "Kriegstrauma" und dessen Darstellungen, die im Roman vorkommen, gelöst werden. Der Ausdruck auf der ersten Seite der Einführung des Romans "Die Schrecken des Ersten Weltkrieges sind die Schrecken aller Kriege", deutet auf das Hauptthema im Roman. Dieser Roman wird auch heute 100 Jahre nach dem Ersten Weltkrieg als ein Zeitzeugen-Dokument angesehen. Der Roman schildert die Erfahrungen eines einfachen Frontsoldaten im Ersten Weltkrieg, den Erich Maria Remarque im Jahre 1927 als er an der Westfront Dienst war geschrieben hat. Im Roman "Im Westen nichts Neues" wird die Geschichte des deutschen Soldaten Paul Bäumer und seiner Kameraden im Ersten Weltkrieg erzählt. Traumata / Kriegstraumata / Kriegserlebnisse der Soldaten an der Front sind ein zentrales Thema des Romans.
'Leutnant Gustl' als eine repräsentative Figur für die
Identitätsdefizite in der Gesellschaft
(2018)
In vorliegender Arbeit haben wir den Versuch unternommen, die Novelle mit dem Titel "Leutnant Gustl" von Arthur Schnitzler im Lichte der wissenschaftlichen Literatur mit dem deskriptiven Verfahren zu analysieren. Es geht darin um einen Konflikt zwischen der inneren Welt des kleinbürgerlichen Protagonisten der k.u.k. Monarchie der Jahrhundertwende, und der Gesellschaft, in der er lebt. Hier wird vorwiegend die Identitätskrise der Figur Leutnant Gustl, die mit seiner Umgebung zu tun hat, und die sich mit der Überwindung derselben auseinandergesetzt. Bei der Analyse wird nicht zuletzt auf die Fragen eingegangen, worin die Identitätsprobleme liegen, wie der Protagonist aus diesen Problemen herauszukommen versucht.
Rolf Schneider gehörte zu jenen DDR-Schriftstellern, deren Romane um 1970 überwiegend in der Bundesrepublik herauskamen. Auch war er Teil der Gruppe von Autoren, die von 1978 bis 1981 langfristige Visa erhielten und zwischen Ost- und Westdeutschland hin- und herpendelten. Es ist anzunehmen, dass der Umstand, gleichsam zwischen den Stühlen zu sitzen, Schneiders Autorschaft in hohem Maß bedingte. Damit ist zugleich die Frage aufgeworfen, in welcher Weise dies der Fall war. Im Beitrag soll dem anhand der 1965 erschienenen Erzählung Metamorphosen nachgegangen werden. Sie bietet sich hier deshalb als Textgrundlage an, da sie eine intertextuelle Relation zu Die Verwandlung von Franz Kafka aufweist, dessen Werk von den Kulturfunktionären der DDR bis in die 70er Jahre hinein abgelehnt und aus dem offiziellen "Erbe"-Kanon ausgeschlossen wurde. Vor diesem Hintergrund ist davon auszugehen, dass die in Metamorphosen enthaltenen Anspielungen auf den Kafka-Text Schneider zur Inszenierung seiner regimekritischen Autorschaft dienten. Wie dies im Einzelnen aussah, ist Gegenstand der Untersuchung, die sich den intertextuellen Bezügen von verschiedenen Seiten annähern wird, um so die Aspekte zu beleuchten, die für die literarische Selbstdarstellung Schneiders maßgeblich sind.
Der vorliegende Beitrag beschäftigt sich mit einer Frage, die aufmerksame Leser von Wolfgang Hilbigs Texten vor Fragen stellt, der Frage nach den Störungen in der Libido seiner Protagonisten, die zugleich Alter-Ego-Figuren im Werk sind. Dass sich diese Störungen über viele verschiedenen Texte und in einer konstant wiederkehrenden Dauer zeigen, wird durch Beispiele nachgewiesen. Es wird eine Erklärung dieses Phänomens am Schluss des Beitrags zur Diskussion gestellt. Dabei geht der Diskurs von den Protagonisten Hilbigs bis in den Diskurs um die Problematik des Autors über.
All linguistics should be media linguistics, but it is not. This thesis is presented by using linguistic landscapes as an example. LL research does not belong to the traditional core of either mainstream linguistics or media linguistics. This is why not everything within power has been done yet to make full use of their thematic, conceptual and methodological possibilities. Visible signs in public space, however, are an everyday phenomenon. You have to pull out all the stops to research them extensively. The distinction between linguistics and media linguistics turns out to be counterproductive. But this does not only apply to the case of linguistic landscapes. It also stands for any comprehensive investigation of language and language use. (Exceptions may be very narrow questions for specific purposes.) The above thoughts are supported by a database of the project „Metropolenzeichen“ with more than 25.000 systematically collected, geocoded and tagged photographs.
Mitochondrial derived reactive oxygen species (mtROS) are known for their signaling qualities in both physiology and pathology. To elucidate mitochondrial complex I-dependent ROS-signaling after lipopolysaccharide (LPS)-stimulation THP-1 macrophages with a knockdown of the transmembrane protein TMEM126B were generated. TMEM knockdown cells (sh126B) showed a reduced assembly of complex I and attenuated mtROS production. In these cells we identified protein oxidization by mtROS upon LPS-treatment using the BIAM switch assay coupled to liquid chromatography and mass spectrometry. One of the identified targets of mtROS was succinate dehydrogenase (SDH) flavoprotein subunit A (SDHA). Oxidation of SDHA decreased its enzymatic activity and pharmacological inhibition of SDH in turn stabilized hypoxia inducible factor (HIF)-1α and caused the subsequent, sustained expression of interleukin-1β (IL-1β). Oxidation of SDHA in sh126B cells was attenuated, while pharmacological inhibition of SDH by atpenin A5 restored IL-1β expression in sh126B cells upon LPS-treatment. Conclusively, oxidation of SDH by mtROS links an altered metabolism, i.e. succinate accumulation to HIF-1-driven, inflammatory changes in macrophages.
Recent research indicates that attentional stimulus selection could be a rhythmic process. In monkey, neurons in V4 and IT exhibit rhythmic spiking activity in the theta range in response to a stimulus. When two stimuli are presented together, the rhythmic neuronal responses to each occur in anti-phase, a result indicative of competitive interactions. In addition, it was recently demonstrated that these alternating oscillations in monkey V4 modulate the speed of saccadic responses to a target flashed on one of the two competing stimuli. Here, we replicate a similar behavioral task in humans (7 participants, each performed 4000 trials) and report a pattern of results consistent with the monkey findings: saccadic response times fluctuate in the theta range (6 Hz), with opposite phase for targets flashed on distinct competing stimuli.
An information-theoretic approach to numerically determine the Markov order of discrete stochastic processes defined over a finite state space is introduced. To measure statistical dependencies between different time points of symbolic time series, two information-theoretic measures are proposed. The first measure is time-lagged mutual information between the random variables Xn and Xn+k, representing the values of the process at time points n and n + k, respectively. The measure will be termed autoinformation, in analogy to the autocorrelation function for metric time series, but using Shannon entropy rather than linear correlation. This measure is complemented by the conditional mutual information between Xn and Xn+k, removing the influence of the intermediate values Xn+k−1, …, Xn+1. The second measure is termed partial autoinformation, in analogy to the partial autocorrelation function (PACF) in metric time series analysis. Mathematical relations with known quantities such as the entropy rate and active information storage are established. Both measures are applied to a number of examples, ranging from theoretical Markov and non-Markov processes with known stochastic properties, to models from statistical physics, and finally, to a discrete transform of an EEG data set. The combination of autoinformation and partial autoinformation yields important insights into the temporal structure of the data in all test cases. For first- and higher-order Markov processes, partial autoinformation correctly identifies the order parameter, but also suggests extended, non-Markovian effects in the examples that lack the Markov property. For three hidden Markov models (HMMs), the underlying Markov order is found. The combination of both quantities may be used as an early step in the analysis of experimental, non-metric time series and can be employed to discover higher-order Markov dependencies, non-Markovianity and periodicities in symbolic time series.
Macrophages are highly versatile cells, which acquire, depending on their microenvironment, pro- (M1-like), or antiinflammatory (M2-like) phenotypes. Here, we studied the role of the G-protein coupled receptor G2A (GPR132), in chemotactic migration and polarization of macrophages, using the zymosan-model of acute inflammation. G2A-deficient mice showed a reduced zymosan-induced thermal hyperalgesia, which was reversed after macrophage depletion. Fittingly, the number of M1-like macrophages was reduced in the inflamed tissue in G2A-deficient mice. However, G2A activation was not sufficient to promote M1-polarization in bone marrow-derived macrophages. While the number of monocyte-derived macrophages in the inflamed paw was not altered, G2A-deficient mice had less macrophages in the direct vicinity of the origin of inflammation, an area marked by the presence of zymosan, neutrophil accumulation and proinflammatory cytokines. Fittingly neutrophil efferocytosis was decreased in G2A-deficient mice and several lipids, which are released by neutrophils and promote G2A-mediated chemotaxis, were increased in the inflamed tissue. Taken together, G2A is necessary to position macrophages in the proinflammatory microenvironment surrounding the center of inflammation. In absence of G2A the macrophages are localized in an antiinflammatory microenvironment and macrophage polarization is shifted toward M2-like macrophages.
Mandelic acid is an important aromatic fine chemical and is currently mainly produced via chemical synthesis. Recently, mandelic acid production was achieved by microbial fermentations using engineered Escherichia coli and Saccharomyces cerevisiae expressing heterologous hydroxymandelate synthases (hmaS). The best-performing strains carried a deletion of the gene encoding the first enzyme of the tyrosine biosynthetic pathway and therefore were auxotrophic for tyrosine. This was necessary to avoid formation of the competing intermediate hydroxyphenylpyruvate, the preferred substrate for HmaS, which would have resulted in the predominant production of hydroxymandelic acid. However, feeding tyrosine to the medium would increase fermentation costs. In order to engineer a tyrosine prototrophic mandelic acid-producing S. cerevisiae strain, we tested three strategies: (1) rational engineering of the HmaS active site for reduced binding of hydroxyphenylpyruvate, (2) compartmentalization of the mandelic acid biosynthesis pathway by relocating HmaS together with the two upstream enzymes chorismate mutase Aro7 and prephenate dehydratase Pha2 into mitochondria or peroxisomes, and (3) utilizing a feedback-resistant version of the bifunctional E. coli enzyme PheA (PheAfbr) in an aro7 deletion strain. PheA has both chorismate mutase and prephenate dehydratase activity. Whereas the enzyme engineering approaches were only successful in respect to reducing the preference of HmaS for hydroxyphenylpyruvate but not in increasing mandelic acid titers, we could show that strategies (2) and (3) significantly reduced hydroxymandelic acid production in favor of increased mandelic acid production, without causing tyrosine auxotrophy. Using the bifunctional enzyme PheAfbr turned out to be the most promising strategy, and mandelic acid production could be increased 12-fold, yielding titers up to 120 mg/L. Moreover, our results indicate that utilizing PheAfbr also shows promise for other industrial applications with S. cerevisiae that depend on a strong flux into the phenylalanine biosynthetic pathway.
Background: Protective effects of vitamin D have been reported in autoimmune and malignant thyroid diseases, though little is known about the underlying mechanism. Sirtuin 1 histon deacethylase (SIRT1) links the vitamin D pathway with regulation of transcription factor FOXO3a, a key player in cell cycle regulation and apoptosis. Aim of the present study was to investigate common single nucleotide polymorphisms (SNP's) in FOXO3a gene in respect to thyroid diseases, as well as to evaluate the hypothesis of Sirtuin1-FOXO3a interaction being a mediator of anti-proliferative vitamin D effects.
Methods: The SNP's FOXO3a rs4946936/rs4945816/rs9400239 were genotyped in 257 patients with differentiated thyroid carcinoma (DTC), 139 patients with Hashimoto thyroiditis (HT) and 463 healthy controls (HC). Moreover, T-helper cells of HC and papillary thyroid cancer cell line BCPAP were incubated with 1,25(OH)2D3 and/or SIRT1 inhibitor Ex-527 in order to elucidate SIRT1- dependent vitamin D effects on cell proliferation and FOXO3a gene expression in vitro.
Results: Patients with DTC tended to carry more often allele C in FOXO3a rs4946936 in comparison to HC (pcorrected = pc = 0.08). FOXO3a rs9400239T and rs4945816C was more frequent in HT in comparison to HC (pc = 0.02 and pc = 0.01, respectively). In both DTC and HT, we could not find a correlation of FOXO3a SNP's with vitamin D status. However, on in vitro level, 1,25(OH)2D3 showed an anti-proliferative effect in both T-helper cells and BCPAP, that was blocked by SIRT1 inhibition (T-helper cells: p = 0.0059, BCPAP: p = 0.04) and accompanied by elevated FOXO3a gene expression in T-helper cells (p = 0.05).
Conclusions: FOXO3a rs9400239T and rs4945816C may constitute risk factors for HT, independent of the vitamin D status.This indicates the implication of FOXO3a in pathogenesis of autoimmune thyroid diseases. The dependency of anti-proliferative vitamin D effects on SIRT1 activity further suggests a key role of vitamin D-SIRT1-FOXO3a axis for protective vitamin D effects.
Bipolar disorder (BD) is a major psychiatric illness affecting around 1% of the global population. BD is characterized by recurrent manic and depressive episodes, and has an estimated heritability of around 70%. Research has identified the first BD susceptibility genes. However, the underlying pathways and regulatory networks remain largely unknown. Research suggests that the cumulative impact of common alleles with small effects explains only around 25–38% of the phenotypic variance for BD. A plausible hypothesis therefore is that rare, high penetrance variants may contribute to BD risk. The present study investigated the role of rare, nonsynonymous, and potentially functional variants via whole exome sequencing in 15 BD cases from two large, multiply affected families from Cuba. The high prevalence of BD in these pedigrees renders them promising in terms of the identification of genetic risk variants with large effect sizes. In addition, SNP array data were used to calculate polygenic risk scores for affected and unaffected family members. After correction for multiple testing, no significant increase in polygenic risk scores for common, BD-associated genetic variants was found in BD cases compared to healthy relatives. Exome sequencing identified a total of 17 rare and potentially damaging variants in 17 genes. The identified variants were shared by all investigated BD cases in the respective pedigree. The most promising variant was located in the gene SERPING1 (p.L349F), which has been reported previously as a genome-wide significant risk gene for schizophrenia. The present data suggest novel candidate genes for BD susceptibility, and may facilitate the discovery of disease-relevant pathways and regulatory networks.
Scholars have debated the taxonomic identity of isolated primate teeth from the Asian Pleistocene for over a century, which is complicated by morphological and metric convergence between orangutan (Pongo) and hominin (Homo) molariform teeth. Like Homo erectus, Pongo once showed considerable dental variation and a wide distribution throughout mainland and insular Asia. In order to clarify the utility of isolated dental remains to document the presence of hominins during Asian prehistory, we examined enamel thickness, enamel-dentine junction shape, and crown development in 33 molars from G. H. R. von Koenigswald's Chinese Apothecary collection (11 Sinanthropus officinalis [= Homo erectus], 21 “Hemanthropus peii,” and 1 “Hemanthropus peii” or Pongo) and 7 molars from Sangiran dome (either Homo erectus or Pongo). All fossil teeth were imaged with non-destructive conventional and/or synchrotron micro-computed tomography. These were compared to H. erectus teeth from Zhoukoudian, Sangiran and Trinil, and a large comparative sample of fossil Pongo, recent Pongo, and recent human teeth. We find that Homo and Pongo molars overlap substantially in relative enamel thickness; molar enamel-dentine junction shape is more distinctive, with Pongo showing relatively shorter dentine horns and wider crowns than Homo. Long-period line periodicity values are significantly greater in Pongo than in H. erectus, leading to longer crown formation times in the former. Most of the sample originally assigned to S. officinalis and H. erectus shows greater affinity to Pongo than to the hominin comparative sample. Moreover, enamel thickness, enamel-dentine junction shape, and a long-period line periodicity value in the “Hemanthropus peii” sample are indistinguishable from fossil Pongo. These results underscore the need for additional recovery and study of associated dentitions prior to erecting new taxa from isolated teeth.

Die Nelke Dianthus carthusianorum wurde nach dem Kartäuserorden benannt. Nach den derzeit geltenden deutschen Rechtschreibregeln ist nur die Schreibweise „Kartäusernelke“ ohne h korrekt. Der tatsächliche Gebrauch (Literatur, Internet) ist jedoch nicht einheitlich. Für die Form ohne h sprechen die etymologische Herkunft und die Übereinstimmung mit anderen europäischen Sprachen, für die Form mit h eine mehr als 500jährige Tradition im deutschen Sprachraum.
Es gibt in der botanischen Taxonomie (bisher) nur einen Autor wissenschaftlicher Pflanzennamen namens Medikus oder Medicus ohne gleichnamige Nomenklatoren neben ihm. Die in BRUMMITT & POWELL (1992) angeführten Standardautoren „L.W.MEDICUS“ und „W.MEDICUS“ sind als nomenklatorisch irrelevant zu ignorieren. Die Autorbezeichnung „MEDIK.“ gilt ausnahmslos für alle infrage kommenden Taxa. Autorbezeichnungen wie „MED.“, „MEDIC.“ oder „MEDICUS“ sind entsprechend zu standardisieren.
In Karten wird die Verbreitung von 49 Alchemilla-Arten im Französischen und Schweizer Jura dargestellt. A. psilopodia wird als Art neu beschrieben. Mehrere Erstnachweise werden erbracht: Neu sind A. oscensis für Mitteleuropa, A. hybrida für die Schweiz, A. jaquetiana für Frankreich, A. firma, A. propinqua, A. speciosa, A. squarrosula für den Jura. Die aus Südwesteuropa einstrahlenden Arten (A. hybrida, A. oscensis, A. vetteri) werden ausführlich beschrieben und in Abbildungen, Bestimmungs- und Merkmalstabellen mit ähnlichen Arten verglichen (A. colorata, A. exigua, A. filicaulis, A. glaucescens, A. monticola, A. plicata, A. propinqua, A. psilopodia, A. strigosula, A. subglobosa).
Es wird eine Übersicht über die in Deutschland vorkommenden Bolboschoenus- Arten gegeben, die Bestimmungsschlüssel und Verbreitungsübersichten mit Listen geprüfter Belege enthält. Herbarrevisionen und Exkursionen sind Grundlagen der Arbeit. In Deutschland sind vier Bolboschoenus- Arten indigen: B. maritimus s. str. ist eine halophile Art der Küsten und Binnensalzstellen; B. laticarpus ist weit verbreitet in Süßwasserhabitaten, besonders in Flussauen; B. planiculmis ist eine seltene Art von Sekundärhabitaten, insbesondere Nassstellen in Feldern, von der aktuelle Funde nur aus Bayern und Sachsen-Anhalt bekannt sind; B. yagara ist ebenfalls eine seltene Art, deren Vorkommen in Fischteichen der sächsischen Lausitz, in Thüringen, Bayern und Baden- Württemberg liegen. Häufigkeiten, mögliche Ausbreitungstendenzen und Schutzbedürftigkeit werden diskutiert.
Angegeben wird jeweils das Sammeldatum des für die Chromosomenzählung verwendeten Materials (Lebendpflanze, Samen) zuzüglich eines eventuell gesammelten Beleges sowie – getrennt durch einen Schrägstrich – Sammeldatum und Aufbewahrungsort eines Beleges der gezählten Pflanze. Wird nur ein Datum angegeben, ist allein die Wildaufsammlung dokumentiert. Die Abkürzungen der Herbarien richten sich nach HOLMGREN & al. (1990, sowie Online-Nachträge). Taxonomie und Nomenklatur richten sich nach der aktuellen deutschen Standardliste (BUTTLER & HAND 2008). Wie bereits in vorhergehenden Folge werden wiederum einige Zählungen aus dem grenznahen Ausland mit aufgenommen.
Die Intention der hiermit fortgesetzten Reihe sowie die Kriterien zur Aufnahme der besprochenen Literatur und der nomenklatorischen Neuigkeiten sind in der Einführung zur ersten Folge in Kochia 1 erläutert. Der Abschnitt „Taxonomie“, der der „Molekularen Phylogenetik“ normalerweise vorangestellt ist, entfällt dieses Mal mangels mitteilenswerter Publikationen. Dies spiegelt in gewisser Weise die Entwicklung an nationalen und internationalen Hochschulen wider.
Im Rheinland fallen zwei frühblühende Capsella-Sippen auf. Die zuerst blühende Sippe, Capsella I genannt, würde man als Teil einer weit gefassten C. bursa-pastoris ansehen. Etwas später blüht C. rubella, eine bisher vermutlich weitgehend übersehene Art des Rheinlandes. Taxonomie und Merkmalsbewertung bei Capsella werden diskutiert.

Bericht über die Tagung "Beziehungskrisen: Deutsch-türkische
Verhältnisse in Literatur und Film"
(2017)
Zwischen dem 14. und 16. November 2017 wurde an der Ege Universität-Izmir eine Internationale Tagung veranstaltet, welche im Rahmen zweier Germanistischer Institutspartnerschaften (GIP) vom Deutschen Akademischen Austauschdienst (DAAD) gefördert wurde. Die Kooperation zwischen der Universität Paderborn und der Ege Universität sowie die Partnerschaft zwischen der Universität Hamburg und der Istanbul Universität trugen dazu bei, dass diese Tagung mit dem Schwerpunkt "Beziehungskrisen: Deutsch-türkische Verhältnisse in Literatur und Film" zustande kam.
Unter der Leitung der Ege Universität und der Beteiligung der Universität Paderborn, Istanbul und Hamburg fand vom 14. bis zum 16. November 2017 die erste internationale/kooperative Vierer-Tagung im Rahmen der Germanistischen Institutspartnerschaft an der Ege Universität in Izmir statt. Wissenschaftler und Interessierte reisten aus verschiedenen Städten wie Istanbul, Ankara, Eskişehir, Berlin, Paderborn, Hildesheim und Hamburg für die vom Deutschen Akademischen Austauschdienst (DAAD) geförderte GIP Tagung an und leisteten mit gebiets- und themenbezogenen Vorträgen einen besonderen Beitrag dazu, eine international sehr vielschichtige Plattform entstehen zu lassen, die mehr als nur den literaturwissenschaftlichen Austausch ermöglichte
Das Exzerpt stellt ein Mittel dar, Fachwissen auf dem Wege der Textreproduktion in individuelles Wissen eines Lernenden umzuwandeln. Dies macht das Exzerpieren zu einer der Kernkompetenzen angehender DeutschlehrerInnen und wirkt sich sowohl auf den Erfolg im Studium als auch im späteren Berufsleben aus. Ziel dieses Aufsatzes ist es, mit textlinguistischen Analysemethoden und -verfahren festzustellen, inwieweit die Studierenden im Lehramtsstudiengang Deutsch als Fremdsprache in der Türkei die Fähigkeit des Exzerpierens als Teilfähigkeit des akademischen Schreibens am Ende ihres Studiums beherrschen. An der Untersuchung nahmen insgesamt 23 Studierende aus dem 4. Studienjahr der Abteilung für Deutsche Sprache und ihre Didaktik der Marmara-Universität in Istanbul teil. Insgesamt wurden 20 von den Studierenden verfasste Exzerpte ausgewertet. Die Auswertung der Studentenexzerpte erfolgte nach drei Hauptbewertungskriterien: Gliederung und Bezug zum Primärtext, inhaltliche Gestaltung des Exzerpts und Strategien beim Schreiben von Exzerpten. Aus den Ergebnissen geht hervor, dass die Exzerpierkenntnisse der meisten an der Untersuchung beteiligten Studierenden am Ende ihres Studiums nicht ausreichend entwickelt sind und sie deshalb vermutlich Schwierigkeiten mit dem Exzerpieren von Texten im weiteren Studium, z.B. Masterstudium haben werden, insbesondere bei der Anfertigung von Seminararbeiten, für die eine Reihe von Aufsätzen zu exzerpieren sind.
Köşker 2015 yılında yayımlanan "Yabancı Dil Öğretiminde Kültür Aktarımı: Fransız Dili Örneği" başlıklı makalesinde geçmişten günümüze süregelen hedeflerin aksine dil öğrenmenin temel amacının artık öğrenilen dili konuşan kişilerle yazılı veya sözlü iletişim kurabilmek olduğunu belirtmiş, ancak Zeuner (1997) gibi o da konuşma ve anlama üzerine kurulu yazılı ve sözlü iletişim yetisini kullanabilmek için sadece dilbilgisi kurallarını bilmenin yetmediğini, bunun yanı sıra etkileşime girilen kişilerin yaşadıkları topluma ilişkin kültürel değerler hakkında da bilgi sahibi olmak ve dili konuşanların sözel olmayan mesajlarını da anlamak gerektiğini vurgulamıştır. Köşker ve Zeuner'in bu görüşlerinden hareketle bu çalışmada Milli Eğitim Bakanlığı Talim ve Terbiye Kurulu Başkanlığının 2016-2017 öğretim yılından itibaren 5 (beş) yıl süreyle ders kitabı olarak kabul ettiği ve okullarda 2016-2017 eğitim-öğretim yılında yaygın olarak kullanılan Türkiye'de hazırlanmış ve basılmış olan Schritt für Schritt Deutsch Ortaöğretim A1.1 Düzeyi Almanca Ders Kitabı (Çelen Öztürk, 2016) içerdiği kültürel öğeler bakımından Tomková'nın (1992) ve Arıkan ve Saraç'ın (2010) geliştirmiş oldukları ölçütler doğrultusunda mercek altına alınmış ve veriler betimsel analiz yöntemi ile çözümlenerek, yorumlanmıştır. Veriler, Schritt für Schritt Deutsch Ortaöğretim A1.1 Düzeyi Almanca Ders Kitabında hedef dilin konuşulduğu ülkenin günlük yaşamına ve kültürüne ilişkin Türkçede 'Ülke Bilgisi' olarak karşılık bulan Landeskunde kavramı bağlamında coğrafi, tarihsel, sayısal, istatistiksel vs. gibi bilgilere yer verildiğini, bunun ötesinde öğrencilerin hedef dil kültürel öğeleri görmelerini ve duymalarını ve bu yolla zihinlerinde hayal edebilmelerini sağlayan ve kendi kültürü ile hedef dilin kültürünü karşılaştırabileceği ve empati kurabileceği düzenlemelere gidildiğini, ancak gerek 'Kültürlerarasılık' kavramı bağlamında yapılması öngörülen etkinliklerin gerekse ‘Ülke Bilgisi’ olarak karşılık bulan Landeskunde kavramı bağlamında sunulan coğrafi, tarihsel, sayısal, istatistiksel vs. gibi bilgilerin sayıca oldukça sınırlı olduğunu ortaya koymuştur. Araştırma kitapta yabancı olanı doğru anlayabilmek için mutlaka bilinmesi gereken hedef dilin konuşulduğu ülkeye has kültürel değerlere çok az değinildiğini ve erek dili konuşanların sözel olmayan mesajlarını da anlayabilme becerisini de geliştirecek türde düzenlemelere gidilmesi gerektiğini ortaya koymuştur.
In the present research a pronunciation training, which was implemented within the scope of the seminar "Reading skills II", is being discussed. Turkish students in their first year, studying German Language Teaching at Uludağ University participated in this research. After a theoretical grounding, the conception of the pronunciation training and how it was implemented in the seminar will be introduced. The aim of this study is to examine, how the detected phonetic problems of the students can be eliminated through a targeted pronunciation training and how it can be perceived by the students. Orientated on the Qualitative Evaluation by Kuckartz et al. (2007) the analysis has been carried out. Therefore a questionnaire and a group-interview have been applied. Considering the evaluated results, possible perspectives for the specific field of research and teaching practice have been presented.
Werbung stellt in einer von Globalisierung und Transkulturalität geprägten Welt ein Phänomen dar, das nicht nur omnipräsent ist und uns mit Glücksversprechen und Idealbildern in Plastik(-schein-)welten verführt, sondern zunehmend als populäre Form der Kunst gepriesen wird, deren Wirkung durch ausgefeilte Formen der Rhetorik sowie eine suggestive bzw. manipulative Bildersprache gekennzeichnet ist. Fach- und insbesondere Fremdsprachen bilden einen wesentlichen Bestandteil im sprachlichen und stilistischen Repertoire der Werbesprache. Der Beitrag gliedert sich denn auch in zwei Abschnitte: Im ersten Teil der Untersuchung wird das sprachliche und stilistische Repertoire (Fachsprachen, Jugendsprache, Dialekt, Fremdsprachen (Anglizismen) der Werbesprache dargestellt. Der zweite Teil der Untersuchung beinhaltet eine exemplarische Analyse von türkischen und deutschen bzw. deutschsprachigen Werbeanzeigen im Hinblick auf die Verwendung von Anglizismen.
Der vorliegende Beitrag beschäftigt sich mit einem Gedicht Heiner Müllers, das dieser in unmittelbarer Reaktion auf den Zusammenbruch des osteuropäischen Sozialismus verfasste. Da dieses Gedicht in mehreren Etappen geschrieben und publiziert wurde, gibt es Einblicke in die von Umbruch und Verwerfungen gekennzeichnete Entstehungssituation, die der Beitrag erläutern will.
Es kann gleichermaßen als eine vorläufige Lebensbilanz des Autors gelesen werden, wo sich selbstkritische Äußerungen zu den Irrtümern mit denen einer geschichtlichen Epoche kreuzen. Da die eingenommene Haltung zu diesem komplexen Veränderungsprozess und die Bewertung dieser Wende durch den Autor auch wiederum einer Selbstkritik unterworfen wurde, versucht der Beitrag, einen Einblick in die geschichtsphilosophische und ästhetische Werkstatt des Autors Heiner Müller zu geben
Alfred Döblin ist einer der erfolgreichen Schriftsteller, der die Eigenschaften der Literatur und Medizinwelt in seinen Werken vereint. Problematische Beziehungen des Menschen mit sich selbst und mit seiner Umgebung, seine Zerrissenheit in der Groβstadt, seelische Krankheiten prägen seine literarischen Werke und seine literarische Kreativität steht unter dem Einfluss seiner medizinischen Kenntnisse und insbesondere unter den seelischen Motiven. Aus diesem Grunde besteht immer die Möglichkeit, in seinen Werken diesen medizinischen Einflüssen häufig zu begegnen.
Döblin stellt in der Erzählung "Die Ermordung einer Butterblume" die Erlebnisse des Herrn Michael Fischer bei einem Waldspaziergang dar. Die Komplexität der Figur wird durch den Erzähler und seine Erzählweise konkretisiert. Denn die Konstruktion des Textes ist ebenso wichtig wie der Inhalt. Deswegen führt die Konstruktion des Textes dazu, den gesamten Text durch den Erzähler und die wechselnden Erzählperspektiven aufzuklären. Außer der wichtigen Funktion des Erzählers wird die Erzählung auch mit der außerordentlichen Figur in Betracht gezogen. Die Figur ist in einer Auseinandersetzung mit sich selbst und hat seelische Probleme. Seine seelischen Probleme werden durch den Erzähler und seine Erzählweise untersucht und aufgeklärt. Die Einflüsse dieser seelischen Probleme werden durch die Verfolgung des Erzählers gefunden und die Spuren/Motive werden durch die Einstellung des Erzählers gegenüber der erzählten Welt gelöst.
Der vorliegende Beitrag beschäftigt sich mit der Frage des Geschlechts der Macht im Kolonialismus anhand der thematischen Konstellation von "Weiblichkeit, Männlichkeit und Asymmetrie" in Alfred Döblins Amazonastrilogie. Anders als frühere Beiträge über die Trilogie, die sich mit den Themen "Kolonialismus", "Interkulturalität", "koloniale Gewalt Struktur" und mit anderen sich auf ästhetische und publizistische Schriften des Autors ergebenden thematischen Schwerpunkten befassen, wird die Dialektik von Macht und Gender im Selbstermächtigungsprozess der Amazonen zunächst als destruktiv für innerindianische Geschlechtsverhältnisse und dann kontraproduktiv für die von eigenen Ehemännern angenommene antikoloniale Strategie betrachtet. Eigene Ehemänner geraten ins Kreuzfeuer der Kritik und Gewalt, wobei antikoloniale Front sozusagen dadurch unterminiert wird. Nachgewiesen wird im Beitrag, wie Amazonen, ihren politischen Zynismus betreibend, eher zu Alliierten der Kolonisatoren werden und unbewusst zur Verankerung des Kolonialismus beitragen. Des Weiteren wird untersucht, wie die selbstreflexionsfähigen und vernunftbegabten Amazonen aus früheren politischen Fehlentscheidungen lernen, ihre gegen eigene Ehemänner gerichteten politischen Gesten und Überzeugungen nun von Grund auf umzudenken, um in eigener Kulturordnung Eintracht zu stiften, wodurch eine zukunftsorientierte gemeinsame antikoloniale Front ermöglicht werden könnte.
We analyse statistical and information-theoretical properties of EEG microstate sequences, as seen through the lens of five different clustering algorithms. Microstate sequences are computed for n = 20 resting state EEG recordings during wakeful rest. The input for all clustering algorithms is the set of EEG topographic maps obtained at local maxima of the spatial variance. This data set is processed by two classical microstate clustering algorithms (1) atomize and agglomerate hierarchical clustering (AAHC) and (2) a modified K-means algorithm, as well as by (3) K-medoids, (4) principal component analysis (PCA) and (5) fast independent component analysis (Fast-ICA). Using this technique, EEG topographies can be substituted with microstate labels by competitive fitting based on spatial correlation, resulting in a symbolic, non-metric time series, the microstate sequence. Microstate topographies and symbolic time series are further analyzed statistically, including static and dynamic properties. Static properties, which do not contain information about temporal dependencies of the microstate sequence include the maximum similarity of microstate maps within and between the tested clustering algorithms, the global explained variance and the Shannon entropy of the microstate sequences. Dynamic properties are sensitive to temporal correlations between the symbols and include the mixing time of the microstate transition matrix, the entropy rate of the microstate sequences and the location of the first local maximum of the autoinformation function. We also test the Markov property of microstate sequences, the time stationarity of the transition matrix and detect periodicities by means of time-lagged mutual information. Finally, possible long-range correlations of microstate sequences are assessed via Hurst exponent estimation. We find that while static properties partially reflect properties of the clustering algorithms, information-theoretical quantities are largely invariant with respect to the clustering method used. As each clustering algorithm has its own profile of computational speed, ease of implementation, determinism vs. stochasticity and theoretical underpinnings, our results convey a positive message concerning the free choice of method and the comparability of results obtained from different algorithms. The invariance of these quantities implies that the tested properties are algorithm-independent, inherent features of resting state EEG derived microstate sequences.
AMP-activated protein kinase (AMPK) is frequently reported to phosphorylate Ser1177 of the endothelial nitric-oxide synthase (eNOS), and therefore, is linked with a relaxing effect. However, previous studies failed to consistently demonstrate a major role for AMPK on eNOS-dependent relaxation. As AMPK also phosphorylates eNOS on the inhibitory Thr495 site, this study aimed to determine the role of AMPKα1 and α2 subunits in the regulation of NO-mediated vascular relaxation. Vascular reactivity to phenylephrine and acetylcholine was assessed in aortic and carotid artery segments from mice with global (AMPKα−/−) or endothelial-specific deletion (AMPKαΔEC) of the AMPKα subunits. In control and AMPKα1-depleted human umbilical vein endothelial cells, eNOS phosphorylation on Ser1177 and Thr495 was assessed after AMPK activation with thiopental or ionomycin. Global deletion of the AMPKα1 or α2 subunit in mice did not affect vascular reactivity. The endothelial-specific deletion of the AMPKα1 subunit attenuated phenylephrine-mediated contraction in an eNOS- and endothelium-dependent manner. In in vitro studies, activation of AMPK did not alter the phosphorylation of eNOS on Ser1177, but increased its phosphorylation on Thr495. Depletion of AMPKα1 in cultured human endothelial cells decreased Thr495 phosphorylation without affecting Ser1177 phosphorylation. The results of this study indicate that AMPKα1 targets the inhibitory phosphorylation Thr495 site in the calmodulin-binding domain of eNOS to attenuate basal NO production and phenylephrine-induced vasoconstriction.
Platelets participate in the development of liver fibrosis in animal models, but little is known about the benefit of antiplatelet agents in preventing liver fibrosis in humans. We therefore explored the relationship between the use of antiplatelet agents and liver fibrosis in a prospective cohort study of patients at high risk of liver fibrosis and cardiovascular events. Consecutive patients undergoing elective coronary angiography at the University Hospital Frankfurt were prospectively included in the present study. Associations between use of antiplatelet agents (acetyl salicylic acid, P2Y12 receptor antagonists) and liver fibrosis were assessed in regression models, and the relationship between platelet‐derived growth factor beta (PDGF‐β) serum concentration, platelets, liver fibrosis, and use of antiplatelet agents was characterized. Out of 505 included patients, 337 (67%) received antiplatelet agents and 134 (27%) had liver fibrosis defined as a FibroScan transient elastography (TE) value ≥7.9 kPa. Use of antiplatelet agents was inversely associated with the presence of liver fibrosis in univariate and multivariate analyses (multivariate odds ratio [OR], 0.67; 95% confidence interval [CI], 0.51‐0.89; P = 0.006). Use of antiplatelet agents was also inversely associated with FibroTest values (beta, –0.38; SD beta, 0.15; P = 0.02). Furthermore, there was a significant correlation between platelet counts and PDGF‐β serum concentration (rho, 0.33; P < 0.0001), but PDGF‐β serum levels were not affected by antiplatelet agents. Conclusion: There is a protective association between the use of antiplatelet agents and occurrence of liver fibrosis. A randomized controlled trial is needed to explore causality and the potential of antiplatelet agents as antifibrotic therapy in patients at risk for liver fibrosis progression.
Adult neurogenesis is regulated by stem cell niche-derived extrinsic factors and cell-intrinsic regulators, yet the mechanisms by which niche signals impinge on the activity of intrinsic neurogenic transcription factors remain poorly defined. Here, we report that MEIS2, an essential regulator of adult SVZ neurogenesis, is subject to posttranslational regulation in the SVZ olfactory bulb neurogenic system. Nuclear accumulation of MEIS2 in adult SVZ-derived progenitor cells follows downregulation of EGFR signaling and is modulated by methylation of MEIS2 on a conserved arginine, which lies in close proximity to nested binding sites for the nuclear export receptor CRM1 and the MEIS dimerization partner PBX1. Methylation impairs interaction with CRM1 without affecting PBX1 dimerization and thereby allows MEIS2 nuclear accumulation, a prerequisite for neuronal differentiation. Our results describe a form of posttranscriptional modulation of adult SVZ neurogenesis whereby an extrinsic signal fine-tunes neurogenesis through posttranslational modification of a transcriptional regulator of cell fate.
Vismodegib, an inhibitor of the Hedgehog signaling pathway, is an approved drug for monotherapy in locally advanced or metastatic basal cell carcinoma (BCC). Data on combined modality treatment by vismodegib and radiation therapy, however, are rare. In the present study, we examined the radiation sensitizing effects of vismodegib by analyzing viability, cell cycle distribution, cell death, DNA damage repair and clonogenic survival in three-dimensional cultures of a BCC and a head and neck squamous cell carcinoma (HNSCC) cell line. We found that vismodegib decreases expression of the Hedgehog target genes glioma-associated oncogene homologue (GLI1) and the inhibitor of apoptosis protein (IAP) Survivin in a cell line- and irradiation-dependent manner, most pronounced in squamous cell carcinoma (SCC) cells. Furthermore, vismodegib significantly reduced proliferation in both cell lines, while additional irradiation only slightly further impacted on viability. Analyses of cell cycle distribution and cell death induction indicated a G1 arrest in BCC and a G2 arrest in HNSCC cells and an increased fraction of cells in SubG1 phase following combined treatment. Moreover, a significant rise in the number of phosphorylated histone-2AX/p53-binding protein 1 (γH2AX/53BP1) foci in vismodegib- and radiation-treated cells was associated with a significant radiosensitization of both cell lines. In summary, these findings indicate that inhibition of the Hedgehog signaling pathway may increase cellular radiation response in BCC and HNSCC cells.
Using photo elicitation to introduce a network perspective on attachment during middle childhood
(2018)
In this article, we develop a child-centered network approach to attachment during middle childhood. Following monotropic ideas, current attachment research focuses on parental attachment figures despite the expansion of the children’s social environment during middle childhood, failing to generate a comprehensive and structured overview of all individuals who ensure the children’s feeling of safety. Relying on quantitative methods, these studies are also dominated by an adult perspective, limiting the children’s contributions. While there have been theoretical drafts of attachment networks during childhood, this article constitutes the first practical implementation. Using photo elicitation interviews and participant observations, we developed an innovative assessment strategy that allows children to exhaustively identify and characterize all their attachment figures on sociostructural and functional dimensions, thus positioning the children at the center of their comprehensive attachment networks that collectively contribute to their feeling of security. We combine qualitative and quantitative data to assess the children’s own understanding of their feeling of security and to locate the individual attachment figure on context-specific social dimensions, thus making the research setting, a clan in Cameroon, an inherent part of the methodological development. The data are translated into multidimensional network diagrams to visualize the children’s perception of their attachment environment and the emerging patterns of their selection. We present an exemplary network, supplementing it with observational data to discuss the ecological validity of our approach.
Comparative proteomics reveals a diagnostic signature for pulmonary head‐and‐neck cancer metastasis
(2018)
Patients with head‐and‐neck cancer can develop both lung metastasis and primary lung cancer during the course of their disease. Despite the clinical importance of discrimination, reliable diagnostic biomarkers are still lacking. Here, we have characterised a cohort of squamous cell lung (SQCLC) and head‐and‐neck (HNSCC) carcinomas by quantitative proteomics. In a training cohort, we quantified 4,957 proteins in 44 SQCLC and 30 HNSCC tumours. A total of 518 proteins were found to be differentially expressed between SQCLC and HNSCC, and some of these were identified as genetic dependencies in either of the two tumour types. Using supervised machine learning, we inferred a proteomic signature for the classification of squamous cell carcinomas as either SQCLC or HNSCC, with diagnostic accuracies of 90.5% and 86.8% in cross‐ and independent validations, respectively. Furthermore, application of this signature to a cohort of pulmonary squamous cell carcinomas of unknown origin leads to a significant prognostic separation. This study not only provides a diagnostic proteomic signature for classification of secondary lung tumours in HNSCC patients, but also represents a proteomic resource for HNSCC and SQCLC.
The multi-valence nature of vanadium means that its geochemical behaviour will be ƒO2-dependent, so that its concentration or V/Sc (or V/Ga), can serve as proxies for oxidation state in mantle peridotites. Compared to Fe3+/Fe2+-based equilibria, such trace elements may be less sensitive to metasomatic processes. To investigate these systematics, we have measured V, Sc, Ga and Fe3+ contents in clinopyroxene from well-characterised spinel peridotite xenoliths from the Massif Central, France. These samples were metasomatised by a variety of agents with different oxidation states.V contents can be modified by metasomatic interactions, and other geochemically similar elements including Sc and Ga can also be added, removed or remain constant. A link between V/Sc and Fe3+-Fe2+ equilibria is apparent. Partial removal of V is caused by different metasomatic agents; the common factor is that all agents were significantly more oxidised than the initial ambient mantle peridotite. This extraction can be understood by a decreasing partition coefficient for V for ΔlogƒO2 > ~FMQ-2. Considering that mineral/melt partitioning of V decreases similarly for all peridotite minerals, the bulk-rock V/Sc will also change during relatively oxidising metasomatic interactions and mirror the results obtained for clinopyroxene.
Latent myofascial trigger points (MTrP) have been linked to several impairments of muscle function. The present study was conducted in order to examine whether a single bout of self-myofascial release using a foam roller is effective in reducing MTrP sensitivity. Fifty healthy, pain-free subjects (26.8±6 years, 21 men) with latent MTrP in the lateral gastrocnemius muscle were included in the randomized, controlled trial. One week after a familiarization session, they were randomly allocated to three groups: (1) static compression of the most sensitive MTrP using a foam roll, (2) slow dynamic foam rolling of the lateral calf and (3) placebo laser acupuncture of the most sensitive MTrP. Treatment duration in each group was 90 seconds. The pressure pain threshold (PPT) of the most sensitive MTrP was assessed using a handheld algometer prior to and after the intervention. A repeated measures analysis of variance (3x2) did not reveal significant between‑group interactions (p>.05) but showed a significant time effect (F=7.715, p<.05). While placebo and dynamic selfmyofascial release did not change MTrP sensitivity (p>.05), static compression of MTrP increased the PPT (2.6±0.8 to 3.0±1.1, d=.35; p<.05). Static self-myofascial release using a foam roller might represent an alternative to reduce pressure pain of latent MTrP. Additional research should aim to extend these findings to patients and athletes with myofascial pain syndromes.
Fungi indirectly affect plant root architecture by modulating soil volatile organic compounds
(2018)
The plant-growth modulating effect of microbial volatile organic compounds (VOCs) has been demonstrated repeatedly. This has most often been performed by exposing plants to VOC released by microbes grown on nutrient rich media. Here, we used soil instead to grow fungi of the Fusarium genus and investigate how VOCs emitted by this system influenced the development of Arabidopsis plants. The volatile profiles of Fusarium strains grown in soil and malt extract were also compared. Our results demonstrate that distinct volatile signatures can be attributed to different Fusarium genetic clades but also highlight a major influence of the growth medium on volatile emission. Furthermore, all soil-grown Fusarium isolates increased primary root length in Arabidopsis by decreasing VOC concentrations in soil. This result represents a major paradigm shift in plant-microbe interactions since growth modulating effects have been attributed so far to the emission and not the consumption of volatile signals.
Tapping the full potential? Jumping performance of volleyball athletes in game-like situations
(2018)
Background: One key issue in elite interactive team sports is the simultaneous execution of motor actions (e.g., dribbling a ball) and perceptual-cognitive tasks (e.g., visually scanning the environment for action choices). In volleyball, one typical situation is to prepare and execute maximal block jumps after multiple-options decision-making and concurrent visual tracking of the ongoing game dynamics to find an optimal blocking location. Based on resource-related dual- and multi-tasking theories simultaneous execution of visual-cognitive and motor tasks may interfere with each other. Therefore, the aim of this study was to investigate whether volleyball-specific perceptual-cognitive demands (i.e., divided attention, decision making) affect blocking performance (i.e., jumping performance and length of the first step after the ready-block-position) compared to relatively isolated jumping performance.
Methods: Twenty-two elite volleyball players (1st – 3rd German league) performed block jumps in front of a net construction in a single-task condition (ST) and in two perceptual (-cognitive) dual-task conditions including a dual-task low (DT_L; presenting a picture of an opponent attack on a screen) and a dual-task high condition (DT_H; presenting videos of an offensive volleyball set play with a two-alternative choice).
Results: The results of repeated-measures ANOVAs showed a significant effect of conditions on jumping performance [F(2,42) = 33.64, p < 0.001, ηp2 = 0.62] and on the length of the first step after the ready-block-position [F(2,42) = 7.90, p = 0.001, ηp2 = 0.27). Post hoc comparisons showed that jumping performance in DT_H (p < 0.001) and DT_L (p < 0.001) was significantly lower than in ST. Also, length of the first step after the ready-block-position in DT_H (p = 0.005) and DT_L (p = 0.028) was significantly shorter than in ST.
Conclusion: Our findings suggest that blocking performance (i.e., jumping height, length of the first step) decreases in elite volleyball players when a perceptual (-cognitive) load is added. Based on the theory of Wickens (2002), this suggests a resource overlap between visual-processing demands for motor performance and for tracking the dynamics of the game. Interference with the consequence of dual-task related performance costs can therefore also be found in elite athletes in their specific motor expert domain.
Die Germanistikabteilung der Philologischen Fakultät in Kronstadt/Braşov veranstaltete in Zusammenarbeit mit der Gesellschaft der Germanisten Rumäniens [GGR] (Zweigstelle Kronstadt) und mit dem Generalkonsulat der Bundesrepublik Deutschland in Hermannstadt zwischen dem 30. März und 01. April 2017 ihre XX. Internationale Tagung zum Thema Luthers Reformation und deren Wirkung auf Sprache, Literatur und Kultur.
Die Kulturabteilung der Deutschen Botschaft Ankara, das DAAD-Informationszentrum Ankara und die Hacettepe Universität boten im Wintersemester 2016 für interessierte Masterstudierende und Doktoranden ein Workshop-Seminar zu transkulturellen Konzepten von Zeit und Raum in den Werken Ilija Trojanows an. Konzepte von Fremdheit, Migration, Transkulturalität sowie Raum und Zeit standen besonders im Fokus der Veranstaltung. In seinen Werken wirft Trojanow den Blick auf die Ausbildung interkultureller Identitäten und die damit einhergehenden Dimensionen von Fremdheit, Ablehnung und Identitäts- bzw. Zugehörigkeitsdiffusionen. Die Entfremdung von der eigenen Kultur und den damit verbundenen Perspektivwechsel thematisiert Trojanow unter anderem in seinem Werk Der Weltensammler.
In diesem Seminar stand jedoch nicht nur der Roman Der Weltensammler im Vordergrund, sondern unterschiedlichste Literatur Trojanows. Angeleitet wurden die Nachwuchswissenschaftler über zwei Präsenzseminare zum Thema Kulturanalyse und Anwendung von Methoden in der Literaturwissenschaft. Der Mehrwert des Workshop-Seminars bestand darin, dass die Studierenden Fragen aus den Werken anhand von Hypothesen direkt an den Autor stellen konnten. Um diese auch anderen Wissenschaftlern nicht vorzuenthalten, entschied man den Workshop aufzunehmen und im Anschluss zu transkribieren. Dieses Transkript bietet eine Stellungnahme über die Literatur und Philosophie Ilija Trojanows an und trägt gleichzeitig zum Textverständnis seiner Werke bei.
Folgende Werke Trojanows wurden für den Workshop ausgewählt:
Meine Olympiade: Ein Amateur, vier Jahre, 80 Disziplinen
Der Weltensammler
Der überflüssige Mensch
Macht und Widerstand
Zu den heiligen Quellen des Islam: Als Pilger nach Mekka und Medina
Die Versuchungen der Fremde: Unterwegs in Arabien, Indien und Afrika
Döner in Walhalla oder welche Spuren hinterlässt der Gast, der keiner mehr ist.
Die Studierenden, die sich eingehend mit der Literatur in Vorlauf-Präsenzseminaren beschäftigt hatten, entwarfen (kontroverse) Hypthesen, die sie Herrn Trojanow im Workshop vortrugen. Folgende Transkription wiederspiegelt einen Abriss über die Literatur Trojanows und zeigt gleichzeitig Antworten, die zum Teil auch aus einem sehr philosophischen Terminus entspringen.
Üniversiteler bilginin üretildiği yerlerdir. Bu bilgiler paylaşıldıkça anlam kazanırlar. Küresel dünyada üniversitelerden beklenen, bu bilgi paylaşımının yoğun olmasıdır. Yabancı dil bilmek bu aşamada oldukça önemlidir. Akademisyenlerin bu bilgi ağına katılım etkinliği, yabancı dili sözlü ve yazılı etkin kullanabilmesine bağlıdır. Bu çalışmanın amacı, öğretim üyelerinin yabancı dil seviyelerinin demografik değişkenlere göre ölçülmesi ve yabancı dil kullanım amaçlarının betimlenmesidir. Çalışmaya 2015 yılında Trakya Üniversitesi'nde çalışan 269 öğretim üyesi katkı sağlamıştır. Öğretim üyelerinin yabancı dil seviyeleri 'Diller için Avrupa Ortak Öneriler Çerçevesi - Ortak Öneri Düzeyleri Genel Basamaklar Kümesi - A1, A2, B1, B2, C1 ve C2' aracılığı ile ölçülmüştür. Yabancı dil kullanım amaçları ise güvenilirlik oranı % 95 olan bir ölçme aracı ile ölçülmüştür. Betimsel bir yaklaşımla yürütülen çalışmada veriler yüzdelik olarak hesaplanmıştır. Verilerin analizi çalışmaya katılan öğretim üyelerinin yaklaşık üçte birinin B1 (%30,1) ve B2 (%30,1) seviyelerinde olduğunu göstermiştir. Ayrıca yabancı dili kullanma amaçları (akademik, eğitim-öğretim ve kişisel) arasında alımlamaya ve üretime yönelik becerilerde farklılıklar tespit edilmiştir.
Das Ziel dieser Arbeit war es herauszufinden, welche Angstgefühle die DaF-Lernenden, die die deutsche Sprache innerhalb und außerhalb des deutschsprachigen Raums lernen, in Gesprächssituationen erleben. In diesem Zusammenhang wurden zwei verschiedene Probandengruppen ausgewählt und Online-Befragungen erstellt, um genauer zu untersuchen, ob es zwischen diesen Gruppen signifikante Unterschiede gibt. Die Ergebnisse, die aus der Datenauswertung erfolgen, sind für beide Lernergruppen verschieden. Nach den untersuchten Sprechtendenzen verhält sich die Gruppe aus der Türkei als eine meist affektiv eingestellte Gruppe, die beim Sprechen zurückhaltend handelt. Dagegen zeigt die Gruppe aus Deutschland tendenziell weniger Zurückhaltung gegenüber dem Sprechen in Bezug auf die emotionalen bzw. kognitionalen Einstellungen. In Bezug auf unterrichtsbezogene Sprechangst ist zu bemerken, dass die meisten Lernenden von beiden Gruppen häufig die gleiche Meinung vertreten.
Die Sprechfertigkeit ist ein Phänomen, das in fremdsprachlichen Lehr- und Lernprozessen sowohl al Mittel (Vermittlungssprache des Lehrenden) als auch als Zielfertigkeit (die es zu erreichen gilt) an Bedeutung gewinnt. Die Sprechfertigkeit, die zu den sprachlichen Fertigkeiten gehört, ist eine schwer zu entwickelnde Fähigkeit, deren Förderung im Unterricht psychologische und kognitive Mühe erfordert. In dieser Arbeit wird betont, dass es möglich ist, die Sprechfertigkeit im universitären Kontext im Rahmen der Deutschlehrerausbildung "so natürlich wie möglich, so künstlich wie nötig!" zu entwickeln; dies berücksichtigend wurde mit Beispielen erwähnt, dass das Rollenspiel und die Dramatisierungstechniken auf die Förderung der Sprechfertigkeit positiv einwirken. Diese Techniken tragen besonders dazu bei, dass der angehende Deutschlehrer einerseits seine eigene Sprechfertigkeit erweitert und andererseits methodisch-didaktische Vorbildimpulse bekommt, die er in seiner beruflichen Laufbahn als Lehrtechnik effektiv anwenden kann.
Im Jahre 1864 haben die Türken angefangen, die deutsche Sprache in den Schulen zu erteilen, nach der Ausrufung der Republik Türkei in 1923 wurde Deutsch als Fremdsprache außerhalb von Ankara, Istanbul und Izmir auch in den Provinzstädten Kastamonu und Sivas als Fachunterricht eingeführt. In der Universität Istanbul wurde im Jahre 1933 durch Mitglieder des Lehrkörpers Einwanderer aus Deutschland die Abteilung für Deutsche Sprache und Literatur an der Philosophischen Fakultät eröffnet. Die vielfältigen Beziehungen zwischen Deutschland und der Türkei sind von großer Bedeutung und haben Einfluss auf die Entwicklung des Deutschen als Fremdsprache in den Lehrplänen. Seit dem Studienjahr 2001-2002 nimmt das Deutsche als zweites Pflichtfach in den Gymnasien seinen Platz ein. Der Fernunterricht geht seit 1728 kontinuierlich weiter und die Bürger in den Entwicklungsländern profitieren von den Vorteilen des Fernunterrichts. in der Geschichte geht der Fernunterricht in der Türkei zurück bis 1927. In diesem Artikel werden die Möglichkeiten für das Lernen des Deutschen als Fremdsprache durch Fernunterricht erklärt.
Bu çalışmada, tarih boyunca yapılmış çeviriler arasından, tarihin seyrine yön verenler içinde bulunan Septuaginta adlı Tevrat çevirisi ve Reşid taşının çevirisi irdelenmektedir. Çalışmanın amacı, çevirinin her zaman sadece işlev odaklı bir uygulamadan ibaret olmadığını; bilakis sosyoloji, siyaset, ekonomi, din gibi alanlarla etkileşim içerisinde bulunan ve insanlık tarihini belirleyebilecek ölçüde önemli bir etkinlik olabileceğini belirginleştirmektir. Çalışmada, ilgili çevirilerin tarihi olgular üzerindeki etkileri ortaya konmaktadır. Çalışma kapsamında irdelenen her bir çeviri etkinliği, ortaya çıkış nedenleri ve - özellikle de tarih akışının seyrini değiştirecek - etkileri bakımından ele alınıp yorumlanmaktadır.
Ardıl çeviride not alma eğitimi konusuna ilişkin Türkçe kaynakların oldukça sınırlı olmasıyla birlikte, not alma, özellikle ardıl çeviri eğitiminde üzerinde durulması gereken önemli bir konudur. Çevirmen adayları büyük oranda, duyduğu her şeyi not alma ile anladığını not alma arasındaki ayrımı algılayacak duyarlılığa henüz sahip olmamaktadırlar. Sözlü çeviride not almanın ilkelerine ilişkin, yabancı kaynaklarda birbirinden farklı çok sayıda görüş olmasına rağmen, çıkarsama yoluyla bazı temel ilkeler belirlemek, özellikle sözlü çeviri eğitimi açısından fayda sağlayacaktır. Çalışmanın amacı, sözlü çeviride not almanın önemini irdelemenin ve söz konusu temel ilkeleri somutlaştırmanın yanı sıra, sözlü çeviri eğitiminde not alma duyarlılığını geliştirici bir açılım sunmakta belirginleşmektedir. Bu çalışma kapsamında önerilen alıştırma, öğrencilerde not alma duyarlılığının ve bilincinin gelişmesine katkı sağlayacak nitelikte olup, duyduğunu anlama, ifade gücü, belleği güçlendirme, bilgi donanımı ve genel kültür konularına da didaktik anlamda önemli ölçüde katkılar sağlayacak nitelikte bir alıştırmadır.
The aim of this article is to compare migration as an intercultural confrontation and translation as a phenomenon creating a "Third Space" for cultural negotiation. In this frame it analyses what role interculturality plays in both areas and how these areas mutually reshape the other.
The study deals with how the deconstructive approaches that have triggered a new understanding in the field influence translation. In this context, the concept of interculturality brought both by translation and migration, should not be considered as a medium for harmonization and assimilation, but as a means of respect to the foreign that challenges the asymmetries and dominance between the powers. In this sense, the study will demonstrate how intercultural migration and translation enabling constructive and productive interaction can function as a dynamic potential for cultures.
Since translation and migration are two major restorative factors for intercultural communication, they create the mobility of people so of cultures which results in a reframing of the obsolete traditional perception of culture that relies on an isolated and homogenous culture model. This communication enables not only a new understanding of the other and a convergence of the cultures involved, but it also promotes a realisation of the self and its borders
Although students make a great effort to learn a foreign language, it is an undeniable fact that they have some difficulties of understanding during communication. One of the prominent reasons of this situation is their having lack of vocabulary rather than grammar knowledge. This situation also effects the motivation of students in the process of learning negatively. Especially, words that have morphological similarities, but semantically different ones cause a problem in the process of learning, which can not be overcome without getting help professionally. The morphological similarities of the words lead students fail to understand different meanings of these kinds of words. For this reason, the purpose of this study is to investigate the words which cause difficulties because of the morphological similarities for the students to learn. As the study handles the subject in this concrete perspective, it contributes to the teachers having problems in teaching aforementioned difficult words.
Atherosclerosis and its sequelae, such as myocardial infarction and stroke, are the leading cause of death worldwide. Vascular endothelial cells (EC) play a critical role in vascular homeostasis and disease. Atherosclerosis as well as its independent risk factors including diabetes, obesity, and aging, are hallmarked by endothelial activation and dysfunction. Metabolic pathways have emerged as key regulators of many EC functions, including angiogenesis, inflammation, and barrier function, processes which are deregulated during atherogenesis. In this review, we highlight the role of glucose, fatty acid, and amino acid metabolism in EC functions during physiological and pathological states, specifically atherosclerosis, diabetes, obesity and aging.
The present study evaluated the tissue response toward a resorbable collagen membrane derived from bovine achilles tendon (test group) in comparison to physiological wound healing (control group). After subcutaneous implantation in Wistar rats over 30 days, histochemical and immunohistochemical methods elucidated the cellular inflammatory response, vascularization pattern, membrane protein and cell absorbance capacity. After 30 days, the test-group induced two different inflammatory patterns. On the membrane surface, multinucleated giant cells (MNGCs) were formed after the accumulation of CD-68-positive cells (macrophages), whereas only mononuclear cells (MNCs) were found within the membrane central region. Peri-implant vascularization was significantly enhanced after the formation of MNGCs. No vessels were found within the central region of the membrane. Physiological wound healing revealed no MNGCs at any time point. These dynamic changes in the cellular reaction and vascularization within the test-group are related typical indications of a foreign body reaction. Due to the membrane-specific porosity, mononuclear cells migrated into the central region, and the membrane maintained its integrity over 30 days by showing no breakdown or disintegration. The ex vivo investigation analyzed the interaction between the membrane and a blood concentrate system, liquid platelet-rich fibrin (liquid PRF), derived from human peripheral blood and consisting of platelets, leukocytes and fibrin. PRF penetrated the membrane after just 15 min. The data question the role of biomaterial-induced MNGCs as a pathological reaction and whether this is acceptable to trigger vascularization or should be considered as an adverse reaction. Therefore, further pre-clinical and clinical studies are needed to identify the types of MNGCs that are induced by clinically approved biomaterials.
Many cellular processes are regulated via pH, and maintaining the pH of different organelles is crucial for cell survival. A pH-sensitive GFP variant, the so-called pHluorin, has proven to be a valuable tool to study the pH of the cytosol, mitochondria and other organelles in vivo. We found that the fluorescence intensity of Endoplasmic Reticulum (ER)-targeted pHluorin in the yeast Saccharomyces cerevisiae was very low and barely showed pH sensitivity, probably due to misfolding in the oxidative environment of the ER. We therefore developed a superfolder variant of pHluorin which enabled us to monitor pH changes in the ER and the cytosol of S. cerevisiae in vivo. The superfolder pHluorin variant is likely to be functional in cells of different organisms as well as in additional compartments that originate from the secretory pathway like the Golgi apparatus and pre-vacuolar compartments, and therefore has a broad range of possible future applications.
Background: Treatment complexity rises in line with the number of drugs, single doses, and administration methods, thereby threatening patient adherence. Patients with multimorbidity often need flexible, individualised treatment regimens, but alterations during the course of treatment may further increase complexity. The objective of our study was to explore medication changes in older patients with multimorbidity and polypharmacy in general practice.
Methods: We retrospectively analysed data from the cluster-randomised PRIMUM trial (PRIoritisation of MUltimedication in Multimorbidity) conducted in 72 general practices. We developed an algorithm for active pharmaceutical ingredients (API), strength, dosage, and administration method to assess changes in physician-reported medication data during two intervals (baseline to six-months: ∆1; six- to nine-months: ∆2), analysed them descriptively at prescription and patient levels, and checked for intervention effects.
Results: Of 502 patients (median age 72 years, 52% female), 464 completed the study. Changes occurred in 98.6% of patients (changes were 19% more likely in the intervention group): API changes during ∆1 and ∆2 occurred in 414 (82.5%) and 338 (67.3%) of patients, dosage alterations in 372 (74.1%) and 296 (59.2%), and changes in API strength in 158 (31.5%) and 138 (27.5%) respectively. Administration method changed in 79 (16%) of patients in both ∆1 and ∆2. Simvastatin, metformin and aspirin were most frequently subject to alterations.
Conclusion: Medication regimens in older patients with multimorbidity and polypharmacy changed frequently. These are mostly due to discontinuations and dosage alterations, followed by additions and restarts. These findings cast doubt on the effectiveness of cross-sectional assessments of medication and support longitudinal assessments where possible.

Objective: Classifications of posture deviations are only possible compared with standard values. However, standard values have been published for healthy male adults but not for female adults.
Design: Observational study.
Setting: Institute of Occupational Medicine, Social Medicine and Environmental Medicine, Goethe-University Frankfurt/Main.
Participants: 106 healthy female volunteers (21–30 years old; 25.1±2.7 years) were included. Their body weight ranged from 46 to 106 kg (60.3±7.9 kg), the heights from 1.53 to 1.82 m (1.69±0.06 m) and the body mass index from 16.9 kg/m² to 37.6 kg/m² (21.1±2.6 kg/m²).
Outcome measures: A three-dimensional back scan was performed to measure the upper back posture in habitual standing. The tolerance ranges and CI were calculated. Group differences were tested by the Wilcoxon Mann-Whitney U test.
Results: In normal posture, the spinal column was marginally twisted to the left, and the vertebrae were marginally rotated to the right. The kyphosis angle is larger than the lumbar angle. Consequently, a more kyphotic posture is observed in the sagittal plane. The habitual posture is slightly scoliotic with a rotational component (scapular depression right, right scapula marginally more dorsally, high state of pelvic right, iliac right further rotated anteriorly).
Conclusions: Healthy young women have an almost ideally balanced posture with minimal ventral body inclination and a marginal scoliotic deviation. Compared with young males, women show only marginal differences in the upper body posture. These values allow a comparison to other studies, both for control and patient data, and may serve as guideline in both clinical practice and scientific studies.
Self-organized robots may develop attracting states within the sensorimotor loop, that is within the phase space of neural activity, body and environmental variables. Fixpoints, limit cycles and chaotic attractors correspond in this setting to a non-moving robot, to directed, and to irregular locomotion respectively. Short higher-order control commands may hence be used to kick the system from one self-organized attractor robustly into the basin of attraction of a different attractor, a concept termed here as kick control. The individual sensorimotor states serve in this context as highly compliant motor primitives. We study different implementations of kick control for the case of simulated and real-world wheeled robots, for which the dynamics of the distinct wheels is generated independently by local feedback loops. The feedback loops are mediated by rate-encoding neurons disposing exclusively of propriosensoric inputs in terms of projections of the actual rotational angle of the wheel. The changes of the neural activity are then transmitted into a rotational motion by a simulated transmission rod akin to the transmission rods used for steam locomotives. We find that the self-organized attractor landscape may be morphed both by higher-level control signals, in the spirit of kick control, and by interacting with the environment. Bumping against a wall destroys the limit cycle corresponding to forward motion, with the consequence that the dynamical variables are then attracted in phase space by the limit cycle corresponding to backward moving. The robot, which does not dispose of any distance or contact sensors, hence reverses direction autonomously.
Objective: To evaluate the efficacy and tolerability of brivaracetam (BRV) in a severely drug refractory cohort of patients with epileptic encephalopathies (EE).
Method: A multicenter, retrospective cohort study recruiting all patients treated with EE who began treatment with BRV in an enrolling epilepsy center between 2016 and 2017.
Results: Forty-four patients (27 male [61%], mean age 29 years, range 6 to 62) were treated with BRV. The retention rate was 65% at 3 months, 52% at 6 months and 41% at 12 months. A mean retention time of 5 months resulted in a cumulative exposure to BRV of 310 months. Three patients were seizure free during the baseline. At 3 months, 20 (45%, 20/44 as per intention-to-treat analysis considering all patients that started BRV including three who were seizure free during baseline) were either seizure free (n = 4; 9%, three of them already seizure-free at baseline) or reported at least 25% (n = 4; 9%) or 50% (n = 12; 27%) reduction in seizures. An increase in seizure frequency was reported in two (5%) patients, while there was no change in the seizure frequency of the other patients. A 50% long-term responder rate was apparent in 19 patients (43%), with two (5%) free from seizures for more than six months and in nine patients (20%, with one [2 %] free from seizures) for more than 12 months. Treatment-emergent adverse events were predominantly of psychobehavioural nature and were observed in 16%.
Significance: In this retrospective analysis the rate of patients with a 50% seizure reduction under BRV proofed to be similar to those seen in regulatory trials for focal epilepsies. BRV appears to be safe and relatively well tolerated in EE and might be considered in patients with psychobehavioral adverse events while on levetiracetam.
Cultural psychology assumes that the ecocultural conditions of a particular setting shape children’s pathways, resulting in multiple adaptive solutions to universal developmental tasks. While the adaptivity of attachment and children’s psychosocial development during the early years has been thoroughly investigated, attachment research during middle childhood continues to reflect Western ideals of family. Adhering to ideas of monotropy, most studies only focus on parental attachment figures. However, this restricted empirical perspective does not only result in a Eurocentric bias, it also neglects theoretical reflections on the growing complexity of attachment during middle childhood, thus only considering a limited selection of all individuals contributing to the children’s feeling of security, even in Western settings. To investigate the variability and adaptivity of attachment during middle childhood, this study assessed children’s attachment figures in two extreme settings of development, introducing an exhaustive network perspective on attachment during this developmental stage. Children of the Cameroonian Nseh (N = 11) and German children from Bad Nauheim (N = 11) identified and differentiated all individuals contributing to their attachment need in an exploratory and transdisciplinary approach. The socio-structural composition of children’s attachment networks follows the context-specific systems of care and concepts of interconnectedness and the ecological features of each setting, resulting in marked differences between both contexts. The functional composition, however, reflects children’s preoccupation with similar developmental challenges across settings. Same-aged peers contribute to the children’s feeling of safety in both settings, thereby deviating from previous reflections on their subordinate relevance during middle childhood. Overall, these results support the adaptiveness of children’s attachment patterns while also demonstrating universal trends across contexts. They highlight the collective nature of attachment during middle childhood that exceeds the impact of individual dyads. Thus, broad and context-sensitive research strategies become a necessary addition to attachment research in order to generate an exhaustive understanding for children’s development across cultural contexts.
Our ability to select relevant information from the environment is limited by the resolution of attention – i.e., the minimum size of the region that can be selected. Neural mechanisms that underlie this limit and its development are not yet understood. Functional magnetic resonance imaging (fMRI) was performed during an object tracking task in 7- and 11-year-old children, and in young adults. Object tracking activated canonical fronto-parietal attention systems and motion-sensitive area MT in children as young as 7 years. Object tracking performance improved with age, together with stronger recruitment of parietal attention areas and a shift from low-level to higher-level visual areas. Increasing the required resolution of spatial attention – which was implemented by varying the distance between target and distractors in the object tracking task – led to activation increases in fronto-insular cortex, medial frontal cortex including anterior cingulate cortex (ACC) and supplementary motor area, superior colliculi, and thalamus. This core circuitry for attentional precision was recruited by all age groups, but ACC showed an age-related activation reduction. Our results suggest that age-related improvements in selective visual attention and in the resolution of attention are characterized by an increased use of more functionally specialized brain regions during the course of development.
The social construction of technological stasis : the stagnating data structure in OpenStreetMap
(2018)
The article aims for examining the ‘technological stasis’ of the data structure in OpenStreetMap – the successful global collaborative geodata project devoted to ‘create and distribute free geographic data for the world’. Digital structures are strongly influenced by continuing stagnation. This technological stasis – the lack of change in technology – influences data in various ways, as demonstrated by the intensive discussion of the issue by computer scientists and software engineers. However, existing research describing stagnating software is often technic centred and fuzzy, while critical research is barely considering issues of technological stasis in the digital context at all. Therefore, this paper aims for enriching this body of knowledge in order to shed light on aging data structures. I reframe technological stasis with a social-constructivist perspective – using the approach of Social Construction of Technology – especially with the concept of technological frames. Based on the case example of OpenStreetMap, my findings suggest that the data structure – and its stasis – is the outcome of competing understandings and perspectives, shaped by power asymmetries. Although the data structure did not significantly change for more than 10 years, I demonstrate that this is not because of a lack of motivation, nor technological difficulties of carrying out such changes. The technological stasis is rather rooted in the dominant position of few project members who are able to change the software design; it is their perception of the project that defines how data should be stored and what features are dispensable.
Adjektivbildungen mit unterschiedlichen Suffixen sind im Deutschen häufig, aber der differenzierte Gebrauch entspricht gewollten Bedeutungsunterschieden. Diese Bildungen scheinen keiner durchgehenden Systematik entsprechen zu wollen, sondern gehorchen in ihrer möglichen Verwendung der Konvention, der herrschenden Übereinkunft über den Alltagssprachgebrauch. Diesen muss man jeweils am Einzelbeispiel erlernen. Das Eindringen in das Verständnis solcher Möglichkeiten verfeinert das Sprachgefühl in erheblichem Maß. Solches kann man auch in den Unterricht einbringen.
Modern Kuramların Postmodern Yansımaları: Okur Odaklı Edebiyat Kuramlarında Okurun Konumlandırılışı
(2017)
20. yüzyılın ikinci yarısından itibaren edebiyat alanında önemli bir paradigma değişikliğinin gerçekleştiği söylenebilir. Bu değişiklik genel olarak edebiyat kuram ve eleştirilerinin o güne kadar ihmal ettiği ancak en başından itibaren edebiyatın en önemli parçası olan okurun yeni bir yönüyle keşfedilmesi ve yeniden tanımlanmasıyla gerçekleşir. Yazar ve onun yazdığı metin karşısında o güne kadar edilgen bir rol biçilen okur, dönemin koşullarının da elverişli olması nedeniyle aşama aşama etken bir role büründürülür. 1970'li yıllardan itibaren ise okurun bu özelliğini ele alan bir dizi yeni bakış açısı ve yaklaşım ortaya çıkar. Özellikle Almanya, Amerika ve Fransa'da ortaya çıkan bu yaklaşımların her birisi beslendikleri felsefi geleneğin etkisi altında farklı bir okur modeli geliştirirler. Bu çalışmada bu farklı okur modellerinden üç tanesi incelenerek okur kavramı ile neyi veya kimi kastettikleri üzerinde durulmuştur. Bu üç farklı yaklaşımın ele alınmasındaki amaç ise, günümüzde edebiyat metnini anlamlandırmada etken bir rol üstlenen okuru tanımlamak üzere kullanılan "postmodern okur" modeline katkılarının olupc olmadığını sorgulamaktır.
Die vorliegende Untersuchung beabsichtigt die Schönheitsauffassung in der deutschen und türkischen Erzählwelt in ihrer Bedeutung, Funktionalität und kulturellen Einbettung herauszuarbeiten. Ausgehend von den Märchen der Brüder Grimm (Erstausgabe von 1812 und 1815) und den türkischen Märchen von Ignácz Kúnos (Erstfassung,1887) werden die Begriffe "schön", "Schönheit" und "Ästhetik" analysiert und zur Diskussion gestellt. Mittels einer Korpusanalyse werden so die Märchentexte einer hermeneutisch-analytischen, mythologischen und kulturtheoretisch-kritischen Betrachtung unterzogen. Ziel dabei sind die Maßstäbe der Schönheit zu hinterfragen. Was wird in der Märchenwelt als "schön" empfunden? Worin liegt die Grenze vom Schönen zum Hässlichen? Hier ist auch zu fragen, inwieweit das kulturelle Umfeld die Auffassung zum Schönen beeinträchtigt
Ingeborg Rapoports Autobiografie geht über eine Autofiktion hinaus und greift auf ihre interkulturellen Erfahrungen auf. Ihr autobiografisches Schreiben konzentriert sich insofern auf ihre unterschiedlichen Erfahrungen in den verschiedenen Heimaten (Kamerun, USA und Deutschland). Der vorliegende Beitrag untersucht Dimensionen ihres interkulturellen Lebenslaufs. Ausgegangen wird davon, dass die postmoderne Autobiographie zum Medium der Interkulturalität geworden ist.
Rapoport versteht sich besonders als Zeugin ihres Jahrhunderts und stellt die Kolonisierung in ihrer Heimat Kamerun, den deutschen Nazismus sowie den Holocaust, die unkritische Zusammenarbeit zwischen Nord und Süd als die einen fruchtbaren interkulturellen Austausch hindernden Faktoren dar.
Exemplarisch wird an Rapoports Äußerungen nachgewiesen, inwiefern Interkulturalität und Engagement Hand in Hand gehen. In ihrem interkulturellen Engagement tritt Rapoport auf als Antikolonialistin, Nazismus- und Holocaustkritikerin und besonders aber auch als eine den Frieden suchende Autorin, deren Denkweise in die Nähe des Levinasschen Humanismus gerückt werden dürfte.
Scharlatane waren für die Gelehrtendiskurse der Frühen Neuzeit von kaum zu überschätzender Bedeutung, da sich anhand ihres Negativbeispiels Verhaltensideale formulieren ließen, die für die Wissenschaft maßgeblich waren. Das Interesse an dieser Figur reichte auch in die Literatur hinein, wo sie in vielfältiger Weise aufgegriffen wurde und um 1800 verstärkt in Erscheinung trat. Christoph Martin Wieland war einer der Autoren, die sich besonders intensiv mit ihr befassten. In seinem Roman Geschichte der Abderiten (1773-1779) inszeniert er den geistigen Gegensatz, der zwischen dem Protagonisten Demokrit, einem beispielhaften Gelehrten, und seinen Mitbürgern, den törichten Abderiten, besteht. Die These des vorliegenden Beitrags lautet, dass Wieland damit auf eine poetische Reflexion von Wissen abzielt, wobei er mit Hilfe des Scharlatanmotivs die wissenschaftlichen Ausschlussmechanismen seiner Zeit ironisiert. Mithin sind es die Bedingungen der Produktion von Wissen, die im Text aufs Korn genommen werden. Dabei spielt Wieland die komischen Konflikte durch, die auftreten können, wenn das der Aufklärung nahestehende Wissenschaftsethos eines Demokrit auf den Eigendünkel einer unaufgeklärten Gesellschaft trifft.

Das wissenschaftliche Interesse auf dem Feld der Germanistik ist in den letzten Jahren in Rumänien, besonders nach der politischen Umgestaltung des Landes sehr stark gestiegen. Der Fachbereich Germanistik der West-Universität Temeswar veranstaltete in Zusammenarbeit mit der Österreich-Bibliothek Temeswar, der Gesellschaft der Germanisten Rumäniens (Zweigstelle Temeswar) und dem Deutschem Kulturzentrum Temeswar zwischen dem 20.-22. Oktober 2016 ihre internationale Tagung zum Thema Germanistik zwischen Regionalität und Internationalität: 60 Jahre Temeswarer Germanistik.
Türkiye ile Almanya arasında siyasi, ekonomik, bilimsel, ticari, kültürel ve daha birçok alanda yoğun bir işbirliği söz konusudur. Ayrıca Almanya’da yaklaşık üç milyon Türkiye vatandaşı yaşamakta ve Türkiye'ye uzun yıllardır en fazla yabancı turist Almanya'dan gelmektedir. Bütün bu nedenlerden dolayı Almanca konuşabilmek Türkiye'de farklı sektörlerden birçok iş kolunda çalışanlarda aranan bir nitelik haline gelmiştir. Turizm bu sektörlerin başında gelmektedir. Turizm çalışanlarının ihtiyaçları doğrultusunda kurslarda, ilgili fakülte ve yüksekokullarda mesleki Almanca dersleri verilmektedir. Mesleki Almanca öğretimi için bilinen dil öğretim yöntemleri kullanılmakla birlikte, ilgili meslek kolunun gerektirdiği dilsel beceriler göz ününde bulundurularak farklı yöntem ve tekniklerden de yararlanılmaktadır. Bu çalışmada turizm mesleki dili tanımlanıp, örneklerle açıklanmış ve yabancı dil öğretim yöntemlerinin özellikleri açıklanarak, turizm için mesleki Almanca bilgi ve becerilerini kazandırmadaki yeterliliği üzerine bir tartışma yürütülmüştür. Çalışmada herhangi bir örneklem grubu üzerinde deney veya gözlem yapılmaksızın, konuyla ilgili yapılan çalışmalar, öğretmen ve öğrenci görüşleri dikkate alınmıştır.
Parkinson’s disease (PD) is characterized by distinct motor and non-motor symptoms. Sleep disorders are the most frequent and challenging non-motor symptoms in PD patients, and there is growing evidence that they are a consequence of disruptions within the circadian system. PD is characterized by a progressive degeneration of the dorsal vagal nucleus and midbrain dopaminergic neurons together with an imbalance of many other neurotransmitters. Mutations in α-synuclein (SNCA), a protein modulating SNARE complex-dependent neurotransmission, trigger dominantly inherited PD variants and sporadic cases of PD. The A53T SNCA missense mutation is associated with an autosomal dominant early-onset familial PD. To test whether this missense mutation affects the circadian system, we analyzed the spontaneous locomotor behavior of non-transgenic wildtype mice and transgenic mice overexpressing mutant human A53T α-synuclein (A53T). The mice were subjected to entrained- and free-running conditions as well as to experimental jet lag. Furthermore, the vesicular glutamate transporter 2 (VGLUT2) in the suprachiasmatic nucleus (SCN) was analyzed by immunohistochemistry. Free-running circadian rhythm and, thus, circadian rhythm generation, were not affected in A53T mice. A53T mice entrained to the light–dark cycle, however, with an advanced phase angle of 2.65 ± 0.5 h before lights off. Moreover, re-entrainment after experimental jet lag was impaired in A53T mice. Finally, VGLUT2 immunoreaction was reduced in the SCN of A53T mice. These data suggest an impaired light entrainment of the circadian system in A53T mice.
Bu çalışmada öğrencilerin öğrenmiş oldukları dilbilgisel yapıyı nasıl işlevsel hale getireceği, pasif halde bulunan dilbilgisel yapının nasıl aktif hale getirileceği teorik ve deneysel bağlamda incelenmiştir. Tek tip pasif alıştırmaların yerine aktif alıştırma tiplerinden seçenek sunularak öğrencilerin bu bilgiyi, dört beceriye aktarımı mümkün kılınmaya çalışılmıştır. Çalışmada dört beceri birbirinden soyutlanmış biçimde değil bütünleştirici şekilde ele alınmıştır.
Bu çalışmada deneysel yöntemin 'kontrol gruplu öntest ve sontest deney' deseni kullanılmıştır. Hem nitel hem de nicel boyutları içeren karma bir çalışmadır. Çalışmada eylemsel ve üretimsel yöntemlerin kullanıldığı deney grubundaki öntest ve sontest puanları arasındaki başarı farkının; geleneksel yöntemin uygulandığı kontrol grubundaki başarı farkından anlamlı derecede fazla olduğu görülmüştür (F(1,48)=366,149; p<0,001). Buradan hareketle deney grubundaki öğrencilerin daha fazla ilerleme gösterdiği ve başarılı oldukları sonucuna varılmıştır.
Dilbilgisi dersinin iletişimsel yetinin geliştirilmesi için bir araç olduğu görüşü deneysel ve uygulamalı olarak araştırılmıştır. Yaratıcı, eyleme ve öğrencilerin üretimine dayalı bir dilbilgisi dersi geliştirilerek geleneksel dilbilgisi dersine alternatif ders modelleri geliştirilmiştir.
Jedes literarische Werk wird durch seinen Titel identifiziert. Buchtitel sollen das Interesse des Lesers wecken und ihn zum Lesen des Werkes anregen. Sie sind wohl meist kurz, geben dennoch einen ersten Hinweis auf den Inhalt und wirken rezeptionssteuernd. Bekannt ist, dass literarische Werke in andere Sprachen nicht selten unter einem anderen Titel oder unter verschiedenen Titeln erscheinen. Ein Beispiel dafür ist Thomas Manns Erzählung Die Betrogene (1953). Sie ist zuerst von Kâmuran Şipal fast 'wortgetreu' unter dem Titel Aldatılmış Kadın [Die Betrogene] (1999) und sodann davon abweichend von Esen Tezel unter dem neuen Titel Aldanan Kadın [wörtlich: Die Sichtäuschende] (2012) ins Türkische übersetzt worden. Im Allgemeinen wird die nichtwortgetreue Übersetzung von Buchtiteln beanstandet und als ein Problem gesehen, was nach translationswissenschaftlich funktionalistischer Auffassung einer differenzierten Betrachtung bedarf. Vorliegende Fallstudie behandelt diverse translationswissenschaftliche Aspekte und Faktoren der unterschiedlichen Betitelungen von Kâmuran Şipal und Esen Tezel und leistet damit einen Beitrag zur Problematik des Übersetzens von literarischen Titeln.
Abnormitäten oder Analogien bei Übersetzungen deutscher und türkischer Nebensatzkonstruktionen
(2016)
Jede Sprache hat ihre eigene grammatikalische Struktur und dementsprechend unterscheidet sich auch der Aufbau der Sätze. Was in der Grammatik als ein Teilsatz bezeichnet wird, ist ein Nebensatz, welcher in jeder Sprache seine eigene Struktur besitzt. Diese strukturellen Merkmale, Unterschiede und Ähnlichkeiten im Deutschen und im Türkischen werden in dieser Arbeit dargestellt und miteinander verglichen. In dieser Arbeit werden die deutschen Nebensatzarten samt den dazugehörigen Beispielen dargestellt. Nach denselben Gesichtspunkten werden auch die jeweiligen türkischen Übersetzungen wiedergegeben. Diese Aufteilung soll als Mittel zum Zweck der übersichtlicheren Darlegung der Nebensätze und zur Erklärung der Übersetzungsmöglichkeiten dienen. Es ist klar, dass eine konkrete Übersetzung mehr oder weniger angleichend bzw. mehr oder weniger verfremdend erscheint, welche auf Varietät der Zielsprache zurückzuführen ist. Die Gegenüberstellung zwischen von Grund aus unterschiedlichen Sprachen scheint in erster Linie in Bezug auf den Wortschatz (z. B. kulturspezifische Begriffe) und Redeweisen getroffen worden zu sein. Sie ist jedoch auch für den grammatikalischen Bereich relevant. Nach diesem Exkurs werden einige deutsche Märchen mit ihren türkischen Übersetzungen verglichen und analysiert
Çeviri eyleminin yüzyıllarla ifade edilen ve Milattan önceki devirlere kadar uzanan tarihine karşın çeviri etkinliğinin öğretilebilir bir olgu olarak ele alınması, bilindiği üzere yeni bir konudur. Bu öğretme işinin eğitme biçimiyle ele alınıp üniversiter eğitim modelleri ile ele alınması ise, görece çok daha yeni bir görüngüdür. Türkiye'de de son birkaç on yıldır çeviri eğitimi veren akademik birimlerin varlığı ile konu tamamı ile akademik mecraya taşınmış ve tartışılmaya başlanmıştır. Bu tartışmalar ise, akademik çeviri eğitimi yoluyla oluşturulması ve/veya geliştirilmesi amaçlanan 'çeviri edinci' kavramı üzerinden yürütülmektedir. Çeviri edinci, akademik çeviri eğitimi açısından merkezi bir konu olarak değerlendirilebilir. Çünkü 'çeviri edinci'nin nasıl tanımlandığı, verilen eğitimin içeriğini ve usulünü belirleyebilecek denli temel bir sorgulamadır.

Chronic kidney disease and diabetes mellitus are associated with extensive media calcification, which leads to increased cardiovascular morbidity and mortality. Here, we investigated the role of autophagy in the pathogenesis of uremic vascular media calcification. DBA/2 mice were fed with high-phosphate diet (HPD) in order to cause vascular calcification. DBA/2 mice on standard chow diet were used as control. In parallel, autophagy and its response to rapamycin, 3-methyladenine (3-MA), and bafilomycin were studied in an in vitro model using mouse vascular smooth muscle cells (MOVAS). DBA/2 mice on HPD developed severe vascular media calcification, which is mirrored in vitro by culturing MOVAS under calcifying conditions. Both, in vitro and in vivo, autophagy significantly increased in MOVAS under calcifying conditions and in aortas of HPD mice, respectively. Histologically, autophagy was located to the aortic Tunica media, but also vascular endothelial cells, and was found to continuously increase during HPD treatment. 3-MA as well as bafilomycin blocked autophagy in MOVAS and increased calcification. Vice versa, rapamycin treatment further increased autophagy and resulted in a significant decrease of vascular calcification in vitro and in vivo. Rapamycin reduced Runx2 transcription levels in aortas and MOVAS to control levels, whereas it increased α-smooth muscle actin and Sm22α transcription in MOVAS to control levels. Furthermore, rapamycin-treated HPD mice survived significantly longer compared to HPD controls. These findings indicate that autophagy is an endogenous response of vascular smooth muscle cells (VSMC) to protect from calcification in uremia. Induction of autophagy by rapamycin protects cells and mice from uremic media calcification possibly by inhibiting osteogenic transdifferentiation of VSMC.
Rapid immune reconstitution (IR) following stem cell transplantation (SCT) is essential for a favorable outcome. The optimization of graft composition should not only enable a sufficient IR but also improve graft vs. leukemia/tumor effects, overcome infectious complications and, finally, improve patient survival. Especially in haploidentical SCT, the optimization of graft composition is controversial. Therefore, we analyzed the influence of graft manipulation on IR in 40 patients with acute leukemia in remission. We examined the cell recovery post haploidentical SCT in patients receiving a CD34+-selected or CD3/CD19-depleted graft, considering the applied conditioning regimen. We used joint model analysis for overall survival (OS) and analyzed the dynamics of age-adjusted leukocytes; lymphocytes; monocytes; CD3+, CD3+CD4+, and CD3+CD8+ T cells; natural killer (NK) cells; and B cells over the course of time after SCT. Lymphocytes, NK cells, and B cells expanded more rapidly after SCT with CD34+-selected grafts (P = 0.036, P = 0.002, and P < 0.001, respectively). Contrarily, CD3+CD4+ helper T cells recovered delayer in the CD34 selected group (P = 0.026). Furthermore, reduced intensity conditioning facilitated faster immune recovery of lymphocytes and T cells and their subsets (P < 0.001). However, the immune recovery for NK cells and B cells was comparable for patients who received reduced-intensity or full preparative regimens. Dynamics of all cell types had a significant influence on OS, which did not differ between patients receiving CD34+-selected and those receiving CD3/CD19-depleted grafts. In conclusion, cell reconstitution dynamics showed complex diversity with regard to the graft manufacturing procedure and conditioning regimen.
Background: Scientifically evaluated cognitive intervention programs are essential to meet the demands of our increasingly aging society. Currently, one of the “hottest” topics in the field is the improvement of working memory function and its potential impact on overall cognition. The present study evaluated the efficacy of WOME (WOrking MEmory), a theory-based working memory training program, in a double-blind, placebo-controlled, and randomized controlled trial (www.drks.de, DRKS00013162).
Methods: N = 60 healthy older adults were allocated to (1) the WOME intervention, (2) an active low-level intervention, or (3) a passive control group. Overall, the intervention groups practiced twelve sessions of 45 min within 4 weeks of their respective training. Transfer effects were measured via an extensive battery of neuropsychological tests and questionnaires both pre-/post-training and at a 3-month follow-up.
Results: WOME led to a significant improvement in working memory function, demonstrated on a non-trained near transfer task and on two different composite scores with moderate to large effect sizes. In addition, we found some indication of relevant impact on everyday life. The effects were short-term rather than stable, being substantially diminished at follow-up with only little evidence suggesting long-term maintenance. No transfer effects on other cognitive functions were observed.
Conclusion: WOME is an appropriate and efficient intervention specifically targeting the working memory system in healthy older adults.

Im Rahmen dieser Studie wurden jeweils ein türkischer und deutscher Gebrauchs-und Informationstext und einige Sätze von literarischen Texten mit Hilfe der Online-Übersetzungsprogramme "google translate", "Babylon", "Almanca Sözlük" und "İngilizceturkce.gen" übersetzt und überprüft, ob, wenn man die Texte in der Zielsprache mit den Ausgangstexten vergleicht, syntaktische und semantische Fehler aufträten und welche der Online-Übersetzungsprogramme beim Übersetzen zuverlässig sind.
Die Daten haben dargelegt, das bei der Sprachkombination Deutsch-Türkisch/Türkisch-Deutsch Gebrauchstexte und Informationstexte, auch wenn sie einige syntaktische und semantische Fehler beinhalten, im Ganzen und Großen in die Zielsprache richtig transferiert werden, wobei literarische Texte einen höheren Anteil an Fehlern beinhalten. Laut der Untersuchungsergebnisse sollten die übersetzten Texte zur Sicherheit immer von jemand Fachkundigem gelesen werden, da beim Übersetzen von ganzen Sätzen bzw. Textpassagen aus der türkischen Sprache ins Deutsche und umgekehrt aus der deutschen Sprache ins Türkische der Sinn nicht immer erfasst wird.
Zur Kontrolle könnten außerdem noch übersetzte Passagen mit verschiedenen Programmen stückweise mehrmals oder in eine Drittsprache z. B. ins Englische übersetzt werden. Bei feststehenden Aussagen bzw. Ausdrücken hingegen ist ein hohes Maß an Aufmerksamkeit erforderlich.
Nucleation and growth of aerosol particles from atmospheric vapors constitutes a major source of global cloud condensation nuclei (CCN). The fraction of newly formed particles that reaches CCN sizes is highly sensitive to particle growth rates, especially for particle sizes <10 nm, where coagulation losses to larger aerosol particles are greatest. Recent results show that some oxidation products from biogenic volatile organic compounds are major contributors to particle formation and initial growth. However, whether oxidized organics contribute to particle growth over the broad span of tropospheric temperatures remains an open question, and quantitative mass balance for organic growth has yet to be demonstrated at any temperature. Here, in experiments performed under atmospheric conditions in the Cosmics Leaving Outdoor Droplets (CLOUD) chamber at the European Organization for Nuclear Research (CERN), we show that rapid growth of organic particles occurs over the range from −25 ∘C to 25 ∘C. The lower extent of autoxidation at reduced temperatures is compensated by the decreased volatility of all oxidized molecules. This is confirmed by particle-phase composition measurements, showing enhanced uptake of relatively less oxygenated products at cold temperatures. We can reproduce the measured growth rates using an aerosol growth model based entirely on the experimentally measured gas-phase spectra of oxidized organic molecules obtained from two complementary mass spectrometers. We show that the growth rates are sensitive to particle curvature, explaining widespread atmospheric observations that particle growth rates increase in the single-digit-nanometer size range. Our results demonstrate that organic vapors can contribute to particle growth over a wide range of tropospheric temperatures from molecular cluster sizes onward.
An aerosol foam formulation of a once-daily, fixed-dose combination of a synthetic vitamin D3 analog/synthetic corticosteroid (calcipotriol [Cal] 50 µg/g and betamethasone dipropionate [BD] 0.5 mg/g) has recently been introduced for the topical treatment of plaque psoriasis in adults. Data from several sources – randomized controlled trials, case reports (as highlighted in this review), and real-world evidence (RWE) – underscore the considerable and rapid clinical response, effectiveness, and favorable safety and tolerability of Cal/BD aerosol foam in mild-to-moderate psoriatic patients previously treated with class 3 or 4 topical corticosteroids, in patients unsatisfied with ongoing phototherapy in combination with topical therapy and in patients with moderate-to-severe psoriasis. In addition, our case series, considered together with other RWE, highlights that Cal/BD aerosol foam is more effective and with greater levels of patient preference and acceptability than comparator preparations. Thus, Cal/BD aerosol foam offers several treatment advantages, including relief of itch, and is an appropriate first-line topical therapy for consideration in patients with psoriasis of any severity.
Damaged mitochondria are selectively eliminated by mitophagy. Parkin and PINK1, gene products mutated in familial Parkinson’s disease, play essential roles in mitophagy through ubiquitination of mitochondria. Cargo ubiquitination by E3 ubiquitin ligase Parkin is important to trigger selective autophagy. Although autophagy receptors recruit LC3-labeled autophagic membranes onto damaged mitochondria, how other essential autophagy units such as ATG9A-integrated vesicles are recruited remains unclear. Here, using mammalian cultured cells, we demonstrate that RABGEF1, the upstream factor of the endosomal Rab GTPase cascade, is recruited to damaged mitochondria via ubiquitin binding downstream of Parkin. RABGEF1 directs the downstream Rab proteins, RAB5 and RAB7A, to damaged mitochondria, whose associations are further regulated by mitochondrial Rab-GAPs. Furthermore, depletion of RAB7A inhibited ATG9A vesicle assembly and subsequent encapsulation of the mitochondria by autophagic membranes. These results strongly suggest that endosomal Rab cycles on damaged mitochondria are a crucial regulator of mitophagy through assembling ATG9A vesicles.
Background: There is no international consensus up to which age women with a diagnosis of triple-negative breast cancer (TNBC) and no family history of breast or ovarian cancer should be offered genetic testing for germline BRCA1 and BRCA2 (gBRCA) mutations. Here, we explored the association of age at TNBC diagnosis with the prevalence of pathogenic gBRCA mutations in this patient group.
Methods: The study comprised 802 women (median age 40 years, range 19–76) with oestrogen receptor, progesterone receptor, and human epidermal growth factor receptor type 2 negative breast cancers, who had no relatives with breast or ovarian cancer. All women were tested for pathogenic gBRCA mutations. Logistic regression analysis was used to explore the association between age at TNBC diagnosis and the presence of a pathogenic gBRCA mutation.
Results: A total of 127 women with TNBC (15.8%) were gBRCA mutation carriers (BRCA1: n = 118, 14.7%; BRCA2: n = 9, 1.1%). The mutation prevalence was 32.9% in the age group 20–29 years compared to 6.9% in the age group 60–69 years. Logistic regression analysis revealed a significant increase of mutation frequency with decreasing age at diagnosis (odds ratio 1.87 per 10 year decrease, 95%CI 1.50–2.32, p < 0.001). gBRCA mutation risk was predicted to be > 10% for women diagnosed below approximately 50 years.
Conclusions: Based on the general understanding that a heterozygous mutation probability of 10% or greater justifies gBRCA mutation screening, women with TNBC diagnosed before the age of 50 years and no familial history of breast and ovarian cancer should be tested for gBRCA mutations. In Germany, this would concern approximately 880 women with newly diagnosed TNBC per year, of whom approximately 150 are expected to be identified as carriers of a pathogenic gBRCA mutation.
