1On the combined effect of soil fertility and topography on tree growth in subtropical forest ecosystems—a study from SE China显示文摘Aims The aim of our research was to understand small-scale effects of topography and soil fertility on tree growth in a forest biodiversity and ecosystem functioning(BEF)experiment in subtropical SE China.Methods Geomorphometric terrain analyses were carried out at a spatial resolution of 5×5 m.Soil samples of different depth increments and data on tree height were collected from a total of 566 plots(667 m2 each).The soils were analyzed for carbon(soil organic carbon[SOC]),nitrogen,acidity,cation exchange capacity(CEC),exchangeable cations and base saturation as soil fertility attributes.All plots were classified into geomorphological units.Analyses of variance and linear regressions were applied to all terrain,soil fertility and tree growth attributes.Important Findings In general,young and shallow soils and relatively small differences in stable soil properties suggest that soil erosion has truncated the soils to a large extent over the whole area of the experiment.This explains the concurrently increasing CEC and SOC stocks downslope,in hollows and in valleys.However,colluvial,carbon-rich sediments are missing widely due to the convexity of the footslopes caused by uplift and removal of eroded sediments by adjacent waterways.The results showed that soil fertility is mainly influenced by topography.Monte-Carlo flow accumulation(MCCA),curvature,slope and aspect significantly affected soil fertility.Furthermore,soil fertility was affected by the different geomorphological positions on the experimental sites with ridge and spur positions showing lower exchangeable base cation contents,especially potassium(K),due to leaching.This geomorphological effect of soil fertility is most pronounced in the topsoil and decreases when considering the subsoil down to 50 cm depth.Few soil fertility attributes affect tree height after 1-2 years of growth,among which C stocks proved to be most important while pH_(KCl)and CEC only played minor roles.Nevertheless,soil acidity and a high proportion of Al on the exchange complex affected tree height even after only 1-2 years growth.Hence,our study showed that forest nutrition is coupled to a recycling of litter nutrients,and does not only depend on subsequent supply of nutrients from the mineral soil.Besides soil fertility,topography affected tree height.We found that especially MCCA as indicator of water availability affected tree growth at small-scale,as well as aspect.Overall,our synthesis on the interrelation between fertility,topography and tree growth in a subtropical forest ecosystem in SE China showed that topographic heterogeneity lead to ecological gradients across geomorphological positions.In this respect,small-scale soil-plant interactions in a young forest can serve as a driver for the future development of vegetation and biodiversity control on soil fertility.In addition,it shows that terrain attributes should be accounted for in ecological research.Thomas Scholten Philipp Goebes Peter Kühn Steffen Seitz Thorsten Assmann Jürgen Bauhus Helge Bruelheide Francois Buscot Alexandra Erfmeier Markus Fischer Werner Härdtle Jin-Sheng He Keping Ma Pascal A.Niklaus Michael Scherer-Lorenzen Bernhard Schmid Xuezheng Shi Zhengshan Song Goddert von Oheimb Christian Wirth Tesfaye Wubet Karsten Schmidt 2017Journal of Plant Ecology2017,10,1:22
2Are there new approaches for diagnosis, therapy guidance and outcome prediction of sepsis?显示文摘Beside many efforts to improve outcome, sepsis is still one of the most frequent causes of death in critically ill patients. It is the most common condition with high mortality in intensive care units. The complexity of the septic syndrome comprises immunological aspects- i.e.,sepsis induced immunosuppression- but is not restricted to this fact in modern concepts. So far, exact mechanisms and variables determining outcome and mortality stay unclear. Since there is no typical risk profile, early diagnosis and risk stratification remain difficult, which hinders rapid and effective treatment initiation. Due to the heterogeneous nature of sepsis, potential therapy options should be adapted to the individual. Biomarkers like C-reactive protein and procalcitonin are routinely used as complementary tools in clinical decision-making. Beyond the acute phase proteins, a wide bunch of promising substances and non-laboratory tools with potential diagnostic and prognostic value is under intensive investigation. So far, clinical decision just based on biomarker assessment is not yet feasible. However, biomarkers should be considered as a complementary approach.Dubravka Kojic Benedikt H Siegler Florian Uhle Christoph Lichtenstern Peter P Nawroth Markus A Weigand Stefan Hofer Thorsten Brenner 2015World Journal of Experimental Medicine2015,5,2:14

12Overview of clinical forensic services in various countries of the European Union显示文摘Examination of a person who has been a victim of a physical or sexual assault may be very important for upcoming legal proceedings.In the context of a clinical forensic examination,physical findings are recorded and biological trace material is gathered and secured.Ideally,all forensic findings are documented in a detailed report combined with photographic docu-mentation,which employs a forensic scale to depict the size of the injuries.However,the integrity of such forensic findings depends particularly on two factors.First,the examination needs to be conducted professionally to ensure that the findings are properly admissible as court evidence.Second,the examination should take place as soon as possible because the opportunity to successfully secure biological samples declines rapidly with time.Access to low-threshold clinical forensic examinations is not evenly provided in all member states of the European Union(EU);in some states,they are not available at all.As part of the JUST_(e)U!(Juridical standards for clinical forensic examinations of victims of violence in Europe)pro-ject,the Ludwig Boltzmann Institute for Clinical Forensic Imaging in Graz,Austria created(in cooperation with its international partner consortium)a questionnaire:the purpose was to collect information about support for victims of physical and/or sexual assault in obtaining a low-threshold clinical forensic examination in various countries of the EU.Our paper pro-vides a summary of the responses and an overview of the current situation concerning pro-vided clinical forensic services.Sophie Kerbacher Michael Pfeifer Reingard Riener-Hofer Andrea Berzlanovich Maeve Eogan Anita Gali(c)Mihic Gregor Haring Petr Hejna Johannes Höller Sorin Hostiuc Michael Klintschar Peter Kovác Astrid Krauskopf Simone Leski Michal Malacka Thorsten Schwark Hanna Sprenger Andrea Verzeletti Duarte Nuno Vieira Sylvia Wolf Kathrin Yen 2020Forensic Sciences Research2020,5,1:1
