This article analyses differences in the attitudes related to climate change of young scholars in environmental science in Qingdao (China) and Hamburg (Germany). The main aim of the article is to evaluate the role of cultural differences for their explanation. We expect no significant differences in the attitudes related to the findings of climate research, since scientific principles are the joint basis of the scientific discourse wordwide. However, we expect that there are differences in the attitudes of the young scholars about the role of science, of the state and of the civil society for dealing with the challenge of climate change. We suggest that these can be explained with substantial cultural differences between both societies, with regard to the role of the state and the civil society for the solution of environmental problems. In order to evaluate these hypotheses, we have conducted a comparative survey among environmental science students in Qingdao (China) and Hamburg (Germany) about their attitudes towards climate change. The findings support our main hypotheses. The young scholars in Qingdao and Hamburg differ substantially in their views of the role of science in society and policymaking. Plausibly, these differences may mainly be explained with differences in the cultural ideas about the role of the state and of the civil society for the solution of environmental problems. Gradual differences in the share of young scholars who think that climate change has anthropogenic causes, may be explained with differences in the curriculum but also by cultural habits. This article makes a new contribution to the scientific debate by exploring the role of cultural differences for differences in the attitudes of young scholars in environmental science in connection with climate change and climate policy in different cultural contexts.

Synthesis of iron（ll） complexes with asymmetric N2O2 coordinating Schiff base-like ligands and their spin crossover properties

引用

Frontiers of Chemical Science and Engineering 2018年第3期12卷 400-408页

作者： Wolfgang Bauer Tanja Ossiander birgit Weber Department of Chemistry University of Bayreuth 95440 Bayreuth Germany

The synthesis of new Schiff base-like ligands with asymmetric substituents pattern and their iron complexes with pyridine as axial ligand is described. Two of the ligands and one of the iron（II） complexes were characterized by single crystal X-ray structure analysis. One of the the iron（II） complexes shows spin crossover behavior while the others remain in the high spin state. The influence of the reduced symmetry of the ligand on the properties of the complexes is discussed.

Intracellular transport of hepatitis B virus

World Journal of Gastroenterology 2007年第1期13卷 39-47页

作者： Michael Kann André Schmitz birgit Rabe CNRS-REGER(UMR 5097) Université Bor-deaux 2146 rue Léo SaignatF-33076 Bordeaux CedexFrance Institute of Medical Virology Fran-kfurter Str.107D-35392 GiessenGermany

For genome mulUplication hepadnaviruses use the transcriptional machinery of the cell that is found within the nucleus. Thus the viral genome has to be transported through the cytoplasm and nuclear pore. The intracytosolic translocation is facilitated by the viral capsid that surrounds the genome and that interacts with cellular microtubules. The subsequent passage through the nuclear pore complexes （NPC） is mediated by the nuclear transport receptors importin α andβ. Importin α binds to the C-terminus of the capsid protein that comprises a nuclear localization signal （NLS）. The exposure of the NLS is regulated and depends upon genome maturation and/or phosphorylation of the capsid protein. As for other karyophilic cargos using this pathway importin α interacts with importin β that facilitates docking of the import complex to the NPC and the passage through the pore. Being a unique strategy, the import of the viral capsid is incomplete in that it becomes arrested inside the nuclear basket, which is a cage-like structure on the karyoplasmic face of the NPC. Presumably only this compartment provides the factors that are required for capsid disassembly and genome release that is restricted to those capsids comprising a mature viral DNA genome.

Product Variability of the ‘Cineole Cassette＇ Monoterpene Synthases of Related Nicotiana Species

Molecular Plant 2011年第6期4卷 965-984页

作者： Anke Fahnrich Katrin Krause birgit Piechulla University of Rostock Institute for Biological Sciences Albert-Einstein-Str. 3 18059 Rostock Germany

Nicotiana species of the section Alatae characteristically emit the floral scent compounds of the ＇cineole cassette＇ comprising 1,8-cineole, limonene, myrcene, α-pinene, β-pinene, sabinene, and α-terpineol. We successfully isolated genes of Nicotiana alata and Nicotiana langsdorfii that encoded enzymes, which produced the characteristic monoter- penes of this ＇cineole cassette＇ with α-terpineol being most abundant in the volatile spectra. The amino acid sequences of both terpineol synthases were 99% identical. The enzymes cluster in a monophyletic branch together with the closely related cineole synthase of Nicotiana suaveolens and monoterpene synthase 1 of Solanum lycopersicum. The cyclization reactions （α-terpineol to 1,8-cineole） of the terpineol synthases of N. alata and N. langsdorfii were less efficient compared to the ＇cineole cassette＇ monoterpene synthases of Arabidopsis thaliana, N. suaveolens, Salvia fruticosa, Salvia officinalis, and Citrus unshiu. The terpineol synthases of IV. alata and N. langsdorfii were localized in pistils and in the adaxial and abaxial epidermis of the petals. The enzyme activities reached their maxima at the second day after anthesis when flowers were fully opened and the enzyme activity in N. alata was highest at the transition from day to night （diurnal rhythm）.

Osteoclast-like giant cell tumors of the pancreas and liver

引用

World Journal of Gastroenterology 2006年第48期12卷 7878-7883页

作者： Juergen Bauditz birgit Rudolph Wolfram Wermke Fourth Department of Medicine Charité University Hospital Berlin Ger-many Institute of Pathology Charité University Hospital Berlin Germany

Osteoclast-like giant cell tumors （OGCT） are rare abdominal tumors, which mainly occur in the pancreas. The neoplasms are composed of two distinct cell populations and frequently show an inhomogenous appearance with cystic structures. However, due to the rarity of these tumors, only very limited clinical data are available. Imaging features and sonographic appearance have hardly been characterized. Here we report on two cases of osteoclast-like giant cell tumors, one located within the pancreas, the other within the liver, in which OGCTs are extremely rare. Both patients were investigated by contrast sonography, which demonstrated a complex, partly cystic and strongly vascularized tumor within the head of the pancreas in the first patient and a large, hypervascularized neoplasm with calcifications within the liver in the second patient. The liver OGCT responded well to a combination of carboplatin, etoposide and paclitaxel. With a combination of surgical resection, radiofrequency ablation and chemotherapy, the patient＇s survival is currently more than 15 too, making him the longest survivor with an OGCT of the liver to date.

Do concentrations in eggs and liver tissue tell the same story of temporal trends of mercury in high Arctic seabirds?

引用

Journal of Environmental Sciences 2018年第6期30卷 65-72页

作者： Mark L.Mallory birgit M.Braune Biology Department Acadia University Environment and Climate Change Canada National Wildlife Research Centre Carleton University

Mercury（Hg） remains a key contaminant of concern in Arctic biota, and monitoring of Hg concentrations in seabird tissues will be an effective approach to track the effects of implementing the Minamata Convention. We examined trends in total Hg（THg） in liver and egg tissues of two Arctic seabirds, thick-billed murres（Uria lomvia） and northern fulmars（Fulmarus glacialis）, between 1976 and 2013 to assess whether both tissues showed similar patterns of Hg change. Hepatic THg was consistently higher than egg THg, and both species had similar egg THg concentrations, but fulmars had higher hepatic THg than *** THg concentrations showed more relative variation through time than *** suggest that egg THg better reflects exposure of birds to THg in local, Arctic prey,whereas liver THg may incorporate longer term, year-round THg exposure. Additional analysis of THg distribution in Arctic seabirds post-laying would help inform interpretation of long-term trends.
