Based on the current knowledge, we draw a model for nuclear envelope organization in Dictyostelium in this Extra View and we review the experimental data that justified this classification. Furthermore we provide unpublished data underscoring the requirement of posttranslational CaaX-box processing for proper protein localization at the nuclear envelope. Sequence comparison of NE81 sequences from four Dictyostelia with bona fide lamins illustrates the evolutional relationship between these proteins. Under certain conditions these usually unicellular social amoebae congregate to form a multicellular body.

After leaving the blood circulation they migrate efficiently towards sites of inflammation. They are guided by chemoattractants released from cells within the inflammatory foci. On a cellular level, directional migration is a consequence of cellular front-rear asymmetry which is induced by the concentration gradient of the chemoattractants. The generation and maintenance of this asymmetry, however, is not yet fully understood. Here we analyzed the paths of chemotacting neutrophils with different stochastic models to gain further insight into the underlying mechanisms. Wildtype chemotacting neutrophils show an anomalous superdiffusive behavior. CXCR2 blockade and TRPC6-knockout cause the tempering of temporal correlations and a reduction of chemotaxis. Importantly, such tempering is found both in vitro and in vivo. These findings indicate that the maintenance of anomalous dynamics is crucial for chemotactic behavior and the search efficiency of neutrophils. The motility of neutrophils and their ability to sense and to react to chemoattractants in their environment are of central importance for the innate immunity. Neutrophils are guided towards sites of inflammation following the activation of G-protein coupled chemoattractant receptors such as CXCR2 whose signaling strongly depends on the activity of Ca2+ permeable TRPC6 channels. It is the aim of this study to analyze data sets obtained in vitro (murine neutrophils) and in vivo (zebrafish neutrophils) with a stochastic mathematical model to gain deeper insight into the underlying mechanisms. The model is based on the analysis of trajectories of individual neutrophils. Bayesian data analysis, including the covariances of positions for fractional Brownian motion as well as for exponentially and power-law tempered model variants, allows the estimation of parameters and model selection. Our model-based analysis reveals that wildtype neutrophils show pure superdiffusive fractional Brownian motion. This so-called anomalous dynamics is characterized by temporal long-range correlations for the movement into the direction of the chemotactic CXCL1 gradient. Pure superdiffusion is absent vertically to this gradient. This points to an asymmetric 'memory' of the migratory machinery, which is found both in vitro and in vivo. CXCR2 blockade and TRPC6-knockout cause tempering of temporal correlations in the chemotactic gradient. This can be interpreted as a progressive loss of memory, which leads to a marked reduction of chemotaxis and search efficiency of neutrophils. In summary, our findings indicate that spatially differential regulation of anomalous dynamics appears to play a central role in guiding efficient chemotactic behavior.}, language = {en} } @article{BaralRoenschRichteretal.2022, author = {Baral, Hans Otto and R{\"o}nsch, Peter and Richter, Udo and Urban, Alexander and Kruse, Julia and Bemmann, Martin and Kummer, Volker and Javier Valencia, Francisco and Huth, Wolfgang}, title = {Schroeteria decaisneana, S. poeltii, and Ciboria ploettneriana (Sclerotiniaceae, Helotiales, Ascomycota), three parasites on Veronica seeds}, series = {Mycological progress : international journal of the German Mycological Society}, volume = {21}, journal = {Mycological progress : international journal of the German Mycological Society}, number = {1}, publisher = {Springer}, address = {Berlin ; Heidelberg}, issn = {1617-416X}, doi = {10.1007/s11557-021-01742-4}, pages = {359 -- 407}, year = {2022}, abstract = {Ciboria ploettneriana, Schroeteria decaisneana, and S. poeltii produce morphologically very similar apothecia emerging from fallen stromatized seeds of Veronica spp., the former two on V. hederifolia agg. in temperate central Europe and S. poeltii on V. cymbalaria in mediterranean southern Europe. They are described and illustrated in detail based on fresh collections or moist chamber cultures of infected seeds. A key is provided to differentiate the three species from their teleomorphs. For the first time, connections between two teleomorphs and two Schroeteria anamorphs are reported. Members of the anamorph-typified genus Schroeteria are known as host-specific plant parasites that infect seeds of different Veronica spp. In earlier times, they were classified in the Ustilaginales (Basidiomycota), but since more than 30 years, they are referred to as false smut fungi producing smut-like chlamydospores, based on light microscopic and ultrastructural studies which referred them to the Sclerotiniaceae (Helotiales). During the present study, rDNA sequences were obtained for the first time from chlamydospores of Schroeteria bornmuelleri (on V. rubrifolia), S. decaisneana (on V. hederifolia), S. delastrina (generic type, on V. arvensis), and S. poeltii (on V. cymbalaria) and from apothecia of C. ploettneriana, S. decaisneana, and S. poeltii. As a result, the anamorph-teleomorph connection could be established for S. decaisneana and S. poeltii by a 100\% ITS similarity, whereas C. ploettneriana could not be connected to a smut-like anamorph. Ciboria ploettneriana in the here-redefined sense clustered in our combined phylogenetic analyses of ITS and LSU in relationship of Sclerotinia s.l., Botrytis, and Myriosclerotinia rather than Ciboria, but its placement was not supported. Its affiliation in Ciboria was retained until a better solution is found. Also Schroeteria poeltii clustered unresolved in this relationship but with a much higher molecular distance. The remaining three Schroeteria spp. formed a strongly supported monophyletic group, here referred to as "Schroeteria core clade", which clustered with medium to high support as a sister clade of Monilinia jezoensis, a member of the Monilinia alpina group of section Disjunctoriae. We observed ITS distances of 5-6.3\% among members of the Schroeteria core clade, but 13.8-14.7\% between this clade and S. poeltii, which appears to be correlated with the deviating chlamydospore morphology of S. poeltii. Despite its apparent paraphyly, Schroeteria is accepted here in a wide sense as a genus distinct from Monilinia, particularly because of its very special anamorphs. A comparable heterogeneity in rDNA analyses was observed in Monilinia and other genera of Sclerotiniaceae. Such apparent heterogeneity should be met with skepticism, however, because the inclusion of protein-coding genes in phylogenetic analyses resulted in a monophyletic genus Monilinia. More sclerotiniaceous taxa should be analysed for protein-coding genes in the future, including Schroeteria. Four syntype specimens of Ciboria ploettneriana in B were reexamined in the present study, revealing a mixture of the two species growing on V. hederifolia agg.

Und auch Hitzewellen, wie sie in den vergangenen Jahren vermehrt aufgetreten sind, bergen gesundheitliche Risiken, welche sich auch in verschiedenen Sch{\"a}tzungen zu Hitzetodesf{\"a}llen wiederfinden. Um diesen Risiken zu begegnen und Sch{\"a}den infolge von Wetterextremen zu reduzieren, entwickeln viele Kommunen bereits Strategien und Konzepte im Kontext der Klimaanpassung und/oder setzen Anpassungsmaßnahmen um. Neben der Entwicklung und Umsetzung eigener Ideen orientieren sich St{\"a}dte dabei u. a. an Leitf{\"a}den und Beispielen aus der Literatur, Erfahrungen aus anderen St{\"a}dten oder an Ergebnissen aus Forschungsprojekten. Dieser Lern- und Transferprozess, der eine {\"U}bertragung von Maßnahmen oder Instrumenten der Klimaanpassung von einem Ort auf einen anderen beinhaltet, ist bislang noch unzureichend erforscht und verstanden. Der vorliegende Bericht untersucht deshalb ebendiesen Lern- und Transferprozess zwischen sowie innerhalb von St{\"a}dten sowie das Transferpotenzial konkreter Wissenstransfer-Medien, Instrumente und Maßnahmen. Damit wird das Ziel verfolgt, ein besseres Verst{\"a}ndnis dieser Prozesse zu entwickeln und einen Beitrag zur Verbesserung des Transfers von kommunalen Klimaanpassungsaktivit{\"a}ten zu leisten. Der vorliegende Inhalt baut dabei auf einer vorangegangenen Analyse des Forschungsstands zum Transfer von Policies durch Haupt et al. (2021) auf und versucht, den bereits generierten Wissensstand auf der Ebene von Policies nun um die Ebene konkreter Instrumente und Maßnahmen zu erg{\"a}nzen sowie durch empirische Befunde zu ausgew{\"a}hlten Maßnahmen zu untermauern. Die Wissens- und Datengrundlage dieses Berichts umfasst einen Mix aus verschiedenen (Online)-Befragungen und Interviews mit Vertreter:innen relevanter Akteursgruppen, vor allem Vertreter:innen von Stadtverwaltungen, sowie den Erfahrungswerten der drei ExTrass-Fallstudienst{\"a}dte Potsdam, Remscheid und W{\"u}rzburg. Nach einer Einleitung besch{\"a}ftigt sich Kapitel 2 mit {\"u}bergeordneten Faktoren der {\"U}bertragbarkeit bzw. des Transfers. Kapitel 2.1 bietet hierbei eine Zusammenfassung zum aktuellen Wissensstand hinsichtlich des Transfers von Policies im Bereich der st{\"a}dtischen Klimapolitik gem{\"a}ß Haupt et al. (2021). Hier werden zentrale Kriterien f{\"u}r einen erfolgreichen Transfer herausgearbeitet, um einen Ankn{\"u}pfungspunkt f{\"u}r die folgenden Inhalte und empirischen Befunde auf der Ebene konkreter Instrumente und Maßnahmen zu bieten. Kapitel 2.2 schließt hieran an und pr{\"a}sentiert Erkenntnisse aus einer weitreichenden Kommunalbefragung. Hierbei wurde untersucht ob und welche Klimaanpassungsmaßnahmen in den St{\"a}dten bereits umgesetzt werden, welche f{\"o}rdernden und hemmenden Aspekte es dabei gibt und welche Erfahrungen beim Transfer von Wissen und Ideen bereits vorliegen. Kapitel 3 untersucht die Rolle verschiedener Medien des Wissenstransfers und widmet sich dabei beispielhaft Leitf{\"a}den zur Klimaanpassung und Maßnahmensteckbriefen. Kapitel 3.1 beantwortet dabei Fragen nach der Relevanz und Zug{\"a}nglichkeit von Leitf{\"a}den, deren St{\"a}rken und Schw{\"a}chen, sowie konkreten Anforderungen vonseiten befragter Personen. Außerdem werden acht ausgew{\"a}hlte Leitf{\"a}den vorgestellt und komprimiert auf ihre Transferpotenziale hin eingesch{\"a}tzt. Kapitel 3.2 betrachtet Maßnahmensteckbriefe als Medien des Wissenstransfers und arbeitet zentrale Aspekte f{\"u}r einen praxisrelevanten inhaltlichen Aufbau heraus, um basierend darauf einen Muster-Maßnahmensteckbrief f{\"u}r Klimaanpassungsmaßnahmen zu entwickeln und vorzuschlagen. Kapitel 4 besch{\"a}ftigt sich mit sehr konkreten kommunalen Erfahrungen rund um den Transfer von sieben ausgew{\"a}hlten Instrumenten und Maßnahmen und bietet zahlreiche empirische Befunde aus den Kommunen, basierend auf der Kommunalbefragung, verschiedenen Interviews und den Erfahrungen aus der Projektarbeit. Die folgenden sieben Instrumente und Maßnahmen wurden ausgew{\"a}hlt, um eine große Breite st{\"a}dtischer Klimaanpassungsaktivit{\"a}ten zu betrachten: 1) Klimafunktionskarten (Stadtklimakarten), 2) Starkregengefahrenkarten, 3) Checklisten zur Klimaanpassung in der Bauleitplanung, 4) Verbot von Schotterg{\"a}rten in Bebauungspl{\"a}nen, 5) Fassadenbegr{\"u}nungen, 6) klimaangepasste Gestaltung von Gr{\"u}n- und Freifl{\"a}chen sowie 7) Handlungsempfehlungen f{\"u}r Betreuungseinrichtungen zum Umgang mit Hitze und Starkregen. F{\"u}r jede dieser Klimaanpassungsaktivit{\"a}ten wird auf Ebene der Kommunen Ziel, Verbreitung und Erscheinungsformen, Umsetzung anhand konkreter Beispiele, f{\"o}rdernde und hemmende Faktoren sowievorliegende Erfahrungen zu und Hinweisen auf Transfer dargestellt. Kapitel 5 schließt den vorliegenden Bericht ab, indem zentrale Transfer-Barrieren aus den gewonnenen Erkenntnissen aufgegriffen und entsprechende Empfehlungen an verschiedene Ebenen der Politik ausgesprochen werden. Diese Empfehlungen zur Verbesserung des Transfers von klimaanpassungsrelevanten Instrumenten, Strategien und Maßnahmen umfassen 1) die Verbesserung des Austauschs zwischen verschiedenen St{\"a}dten, 2) die Verbesserung der Zug{\"a}nglichkeit von Wissen und Erfahrungen, 3) die Schaffung von Vernetzungsstrukturen innerhalb von St{\"a}dten sowie 4) bestehende Wissensl{\"u}cken zu schließen.

Im Projekt standen folgende vier Leitfragen im Fokus: • Wie verbreitet sind Klimaanpassungsaktivit{\"a}ten in Großst{\"a}dten und gr{\"o}ßeren kreisfreien Mittelst{\"a}dten in Deutschland? • Welche hemmenden und beg{\"u}nstigenden Faktoren beeinflussen die Klimaanpassung? • Welche Maßnahmen der Klimaanpassung werden tats{\"a}chlich umgesetzt, und wie kann die Umsetzung verbessert werden? Was behindert? • Inwiefern lassen sich Beispiele guter Praxis auf andere St{\"a}dte {\"u}bertragen, adaptieren oder weiterentwickeln? Die Hauptergebnisse zu diesen Fragestellungen sind im vorliegenden Bericht zusammengefasst.}, language = {de} } @article{MantzoukiLurlingFastneretal.2018, author = {Mantzouki, Evanthia and Lurling, Miquel and Fastner, Jutta and Domis, Lisette Nicole de Senerpont and Wilk-Wozniak, Elzbieta and Koreiviene, Judita and Seelen, Laura and Teurlincx, Sven and Verstijnen, Yvon and Krzton, Wojciech and Walusiak, Edward and Karosiene, Jurate and Kasperoviciene, Jurate and Savadova, Ksenija and Vitonyte, Irma and Cillero-Castro, Carmen and Budzynska, Agnieszka and Goldyn, Ryszard and Kozak, Anna and Rosinska, Joanna and Szelag-Wasielewska, Elzbieta and Domek, Piotr and Jakubowska-Krepska, Natalia and Kwasizur, Kinga and Messyasz, Beata and Pelechata, Aleksandra and Pelechaty, Mariusz and Kokocinski, Mikolaj and Garcia-Murcia, Ana and Real, Monserrat and Romans, Elvira and Noguero-Ribes, Jordi and Parreno Duque, David and Fernandez-Moran, Elisabeth and Karakaya, Nusret and Haggqvist, Kerstin and Demir, Nilsun and Beklioglu, Meryem and Filiz, Nur and Levi, Eti E. and Iskin, Ugur and Bezirci, Gizem and Tavsanoglu, Ulku Nihan and Ozhan, Koray and Gkelis, Spyros and Panou, Manthos and Fakioglu, Ozden and Avagianos, Christos and Kaloudis, Triantafyllos and Celik, Kemal and Yilmaz, Mete and Marce, Rafael and Catalan, Nuria and Bravo, Andrea G. and Buck, Moritz and Colom-Montero, William and Mustonen, Kristiina and Pierson, Don and Yang, Yang and Raposeiro, Pedro M. and Goncalves, Vitor and Antoniou, Maria G. and Tsiarta, Nikoletta and McCarthy, Valerie and Perello, Victor C. and Feldmann, Tonu and Laas, Alo and Panksep, Kristel and Tuvikene, Lea and Gagala, Ilona and Mankiewicz-Boczek, Joana and Yagci, Meral Apaydin and Cinar, Sakir and Capkin, Kadir and Yagci, Abdulkadir and Cesur, Mehmet and Bilgin, Fuat and Bulut, Cafer and Uysal, Rahmi and Obertegger, Ulrike and Boscaini, Adriano and Flaim, Giovanna and Salmaso, Nico and Cerasino, Leonardo and Richardson, Jessica and Visser, Petra M. and Verspagen, Jolanda M.

Lakes, as providers of numerous ecosystem services, face multiple stressors that threaten their functioning. Harmful cyanobacterial blooms are a persistent problem resulting from nutrient pollution and climate-change induced stressors, like poor transparency, increased water temperature and enhanced stratification. Consistency in data collection and analysis methods is necessary to achieve fully comparable datasets and for statistical validity, avoiding issues linked to disparate data sources. The European Multi Lake Survey (EMLS) in summer 2015 was an initiative among scientists from 27 countries to collect and analyse lake physical, chemical and biological variables in a fully standardized manner. This database includes in-situ lake variables along with nutrient, pigment and cyanotoxin data of 369 lakes in Europe, which were centrally analysed in dedicated laboratories. Publishing the EMLS methods and dataset might inspire similar initiatives to study across large geographic areas that will contribute to better understanding lake responses in a changing environment.}, language = {en} } @misc{MantzoukiLuerlingFastneretal.2018, author = {Mantzouki, Evanthia and L{\"u}rling, Miquel and Fastner, Jutta and Domis, Lisette Nicole de Senerpont and Wilk-Wo{\'{z}}niak, Elżbieta and Koreiviene, Judita and Seelen, Laura and Teurlincx, Sven and Verstijnen, Yvon and Krztoń, Wojciech and Walusiak, Edward and Karosienė, Jūratė and Kasperovičienė, Jūratė and Savadova, Ksenija and Vitonytė, Irma and Cillero-Castro, Carmen and Budzyńska, Agnieszka and Goldyn, Ryszard and Kozak, Anna and Rosińska, Joanna and Szeląg-Wasielewska, Elżbieta and Domek, Piotr and Jakubowska-Krepska, Natalia and Kwasizur, Kinga and Messyasz, Beata and Pełechata, Aleksandra and Pełechaty, Mariusz and Kokocinski, Mikolaj and Garc{\´i}a-Murcia, Ana and Real, Monserrat and Romans, Elvira and Noguero-Ribes, Jordi and Duque, David Parre{\~n}o and Fern{\´a}ndez-Mor{\´a}n, El{\´i}sabeth and Karakaya, Nusret and H{\"a}ggqvist, Kerstin and Beklioğlu, Meryem and Filiz, Nur and Levi, Eti E. and Iskin, Uğur and Bezirci, Gizem and Tav{\c{s}}anoğlu, {\"U}lk{\"u} Nihan and {\"O}zhan, Koray and Gkelis, Spyros and Panou, Manthos and Fakioglu, {\"O}zden and Avagianos, Christos and Kaloudis, Triantafyllos and {\c{C}}elik, Kemal and Yilmaz, Mete and Marc{\´e}, Rafael and Catal{\´a}n, Nuria and Bravo, Andrea G. and Buck, Moritz and Colom-Montero, William and Mustonen, Kristiina and Pierson, Don and Yang, Yang and Raposeiro, Pedro M. and Gon{\c{c}}alves, V{\´i}tor and Antoniou, Maria G. and Tsiarta, Nikoletta and McCarthy, Valerie and Perello, Victor C. and Feldmann, T{\~o}nu and Laas, Alo and Panksep, Kristel and Tuvikene, Lea and Gagala, Ilona and Mankiewicz-Boczek, Joana and Yağc{\i}, Meral Apayd{\i}n and {\c{C}}{\i}nar, Şakir and {\c{C}}apk{\i}n, Kadir and Yağc{\i}, Abdulkadir and Cesur, Mehmet and Bilgin, Fuat and Bulut, Cafer and Uysal, Rahmi and Obertegger, Ulrike and Boscaini, Adriano and Flaim, Giovanna and Salmaso, Nico and Cerasino, Leonardo and Richardson, Jessica and Visser, Petra M. and Verspagen, Jolanda M.

The development of completely new drugs for such a novel disease is a challenging, time intensive process. Despite researchers around the world working on this task, no effective treatments have been developed yet. This emphasizes the importance of drug repurposing, where treatments are found among existing drugs that are meant for different diseases. A common approach to this is based on knowledge graphs, that condense relationships between entities like drugs, diseases and genes. Graph neural networks (GNNs) can then be used for the task at hand by predicting links in such knowledge graphs. Expanding on state-of-the-art GNN research, Doshi et al. recently developed the Dr-COVID model. We further extend their work using additional output interpretation strategies. The best aggregation strategy derives a top-100 ranking of 8,070 candidate drugs, 32 of which are currently being tested in COVID-19-related clinical trials. Moreover, we present an alternative application for the model, the generation of additional candidates based on a given pre-selection of drug candidates using collaborative filtering. In addition, we improved the implementation of the Dr-COVID model by significantly shortening the inference and pre-processing time by exploiting data-parallelism. As drug repurposing is a task that requires high computation and memory resources, we further accelerate the post-processing phase using a new emerging hardware-we propose a new approach to leverage the use of high-capacity Non-Volatile Memory for aggregate drug ranking.}, language = {en} } @article{OttoKernHauptetal.2021, author = {Otto, Antje and Kern, Kristine and Haupt, Wolfgang and Eckersley, Peter and Thieken, Annegret}, title = {Ranking local climate policy}, series = {Climatic change : an interdisciplinary, international journal devoted to the description, causes and implications of climatic change}, volume = {167}, journal = {Climatic change : an interdisciplinary, international journal devoted to the description, causes and implications of climatic change}, number = {1-2}, publisher = {Springer}, address = {Dordrecht}, issn = {0165-0009}, doi = {10.1007/s10584-021-03142-9}, pages = {23}, year = {2021}, abstract = {Climate mitigation and climate adaptation are crucial tasks for urban areas and can involve synergies as well as trade-offs. However, few studies have examined how mitigation and adaptation efforts relate to each other in a large number of differently sized cities, and therefore we know little about whether forerunners in mitigation are also leading in adaptation or if cities tend to focus on just one policy field. This article develops an internationally applicable approach to rank cities on climate policy that incorporates multiple indicators related to (1) local commitments on mitigation and adaptation, (2) urban mitigation and adaptation plans and (3) climate adaptation and mitigation ambitions. We apply this method to rank 104 differently sized German cities and identify six clusters: climate policy leaders, climate adaptation leaders, climate mitigation leaders, climate policy followers, climate policy latecomers and climate policy laggards. The article seeks explanations for particular cities' positions and shows that coping with climate change in a balanced way on a high level depends on structural factors, in particular city size, the pathways of local climate policies since the 1990s and funding programmes for both climate mitigation and adaptation.}, language = {en} }
