Based on new scientific developments and experience of the regulation of chemical compounds, a working group of the Gesellschaft fuer Umweltmutationsforschung (GUM), a German-speaking section of the European Environmental Mutagen Society, proposes a simple and straightforward approach to genotoxicity testing. This strategy is divided into basic testing (stage I) and follow-up testing (stage II). Stage I consists of a bacterial gene mutation test plus an in vitro micronucleus test, therewith covering all mutagenicity endpoints. Stage II testing is in general required only if relevant positive results occur in stage I testing and will usually be in vivo. However, an isolated positive bacterial gene mutation test in stage I can be followed up with a gene mutation assay in mammalian cells. If this assay turns out negative and there are no compound-specific reasons for concern, in vivo follow-up testing may not be required. In those cases where in vivo testing is indicated, a single study combining the analysis of micronuclei in bone marrow with the comet assay in appropriately selected tissues is suggested. Negative results for both end points in relevant tissues will generally provide sufficient evidence to conclude that the test compound is nongenotoxic in vivo. Compounds which were recognized as in vivo somatic cell mutagens/genotoxicants in this hazard identification step will need further testing. In the absence of additional data, such compounds will have to be assumed to be potential genotoxic carcinogens and potential germ cell mutagens.

This paper traces the formation of the German “Gesellschaft für psychologische Forschung” (“Society for Psychological Research”), whose constitutive branches in Munich and Berlin were originally founded as inlets for alternatives to Wundtian experimental psychology from France and England, that is, experimental researches into hypnotism and alleged supernormal phenomena. By utilizing the career trajectories of Max Dessoir and Albert von Schrenck-Notzing as founding members of the “Gesellschaft,” this paper aims to open up novel perspectives regarding extra-scientific factors involved in historically determining the epistemological and methodological boundaries of nascent psychology in Germany.

The Anatomische Gesellschaft and National Socialism - A preliminary analysis based on the society proceedings.

PubMed

Winkelmann, Andreas

2012-06-01

The Anatomische Gesellschaft (AG) is an international society for the anatomical sciences and at the same time the main organising body for German anatomists. This study analyses how the AG went through the years of National Socialism. As the society does not possess archival material from that time, the analysis is mainly based on the society proceedings (Verhandlungen der Anatomischen Gesellschaft) published annually after each meeting from 1934 to 1939 and again in 1950. During the period of National Socialism, the AG kept its international status against demands to make it a purely German society. It did not introduce anti-Jewish regulations or the Führer principle into its bylaws. The membership directories reveal that it was at least possible for members whose career was disrupted by Nazi policies to remain on the membership lists throughout the Nazi period. However, in contrast to later assumptions that no persecuted member of the AG was ever struck from its register, 17 of 57 persecuted members left the society between 1933 and 1939. The membership of six of these members was cancelled, officially for unpaid fees. However, other members with much longer arrears were not cancelled. To date, no additional historical information is available to assess the circumstances of these cancellations. In general, it remains remarkable that, in contrast to many other societies, the AG did not follow the path of preemptive obedience towards the new rulers. More archival sources need to be uncovered to elucidate the external influences and internal negotiations behind the published documents. Copyright © 2012. Published by Elsevier GmbH.
Gesellschaft, Lebensgemeinschaft, Ökosystem - Über die Kongruenz von politischen und ökologischen Theorien der Entwicklung

Voigt, Annette

Im Jahr 1859 veröffentlichte Charles Darwin "On the Origin of Species“. Seine Evolutionstheorie ist das wohl spektakulärste Beispiel einer naturwissenschaftlichen Theorie großer gesellschaftlicher Relevanz. Ihre verschiedenen Facetten wurden in der Öffentlichkeit kontrovers diskutiert, unter anderem auch ihre Anwendung zur Erklärung von Zuständen und Prozessen menschlicher Gesellschaften. Zum Teil wurde die Seiensweise der Natur - scheinbar unabhängig von gesellschaftlichen Interessen - für die Erklärung und Legitimation gesellschaftlicher Zustände oder die Legitimation von politischen Ideologien herangezogen (Sozialdarwinismus). Denn Gesellschaft funktioniere ja so, wie Darwin die Natur erklärt habe: es herrsche z. B. Konkurrenzkampf, Auslese und Arbeitsteilung, Erfolg hätten diejenigen, die sich an die Bedingungen am Besten anpassten.

Die Deutsche Statistische Gesellschaft in der Weimarer Republik und während der Nazidiktatur

Wilke, Jürgen

Nach anfänglichen Schwierigkeiten durch den 1. Weltkrieg erlangte die Deutsche Statistische Gesellschaft (DStatG) unter dem renommierten Statistiker und Vorsitzenden der DStatG, Friedrich Zahn, durch eine Vielzahl von Aktivitäten hohes Ansehen. Es gab Bestrebungen, Statistiker aus allen Arbeitsfeldern der Statistik in die DStatG zu integrieren, wobei die "Mathematische Statistik" nur zögerlich akzeptiert wurde (Konjunkturforschung, Zeitreihenanalyse). Nach der Machtübernahme 1933 durch Adolf Hitler geriet die DStatG in das Fahrwasser nationalsozialistischer Ideologie und Politik (Führerprinzip, Gleichschaltung des Vereinswesens). Damit war eine personelle Umstrukturierung in der DStatG verbunden. Politisch Missliebige und rassisch Verfolgte mussten die DStatG verlassen (Bernstein, Freudenberg, Gumbel u.a.). Unter den Statistikern gab es alle Abstufungen im Verhalten zum Regime von Ablehnung und zwangsweiser Anpassung über bereitwilliges Mitläufertum bis zu bewusster Täterschaft. Besonders die Bevölkerungsstatistik wurde durch die NS- Rassenpolitik auf lange Sicht diskreditiert. Im Rahmen von Wirtschaftsplanung und Aufrüstung wurden neue zukunftsträchtige statistische Modelle (Grünig, Bramstedt, Leisse) entwickelt.
Cosmopolitan sociology and the classical canon: Ferdinand Tönnies and the emergence of global Gesellschaft.

Inglis, David

2009-12-01

How relevant are figures from the classical sociological canon for present day efforts to found cosmopolitan forms of sociological thought? According to the critique of Ulrich Beck, the classical sociologists remain far too wedded to nation-state-centred ways of thinking to play an important role in the development of cosmopolitan sociology. This paper argues that such a critique fails to account for the ways in which certain classical sociologists were attuned to the emerging cosmopolitical conditions of their own time, were not wholly wedded to nation-state-based conceptualizations, and thus can function as both groundings of, and inspirations for, cosmopolitan sociological endeavours. The apparently unpromising case of Tönnies is focused on, the paper showing how he outlined an account of how and why a planet-spanning condition of Gesellschaft developed a position which diverges from and counterpoints Marx's analysis of similar phenomena in important ways. The stereotype of Tönnies as an arch-conservative is also dissolved, allowing him to be considered as one of the most important antecedents of contemporary cosmopolitan sociological practice and a canonical figure still relevant for present-day purposes.
Analysis of steam generator tube rupture transients with single failure

DOE Office of Scientific and Technical Information (OSTI.GOV)

Trambauer, K.

The Gesellschaft fuer Reaktorsicherheit is engaged in the collection and evaluation of light water reactor operating experience as well as analyses for the risk study of the pressurized water reactor (PWR). Within these activities, thermohydraulic calculations have been performed to show the influence of different boundary conditions and disturbances on the steam generator tube rupture (SGTR) transients. The analyses of these calculations have focused on the measures and systems needed to cope with an SGTR. The reference plant for this analysis is a 1300-MW(e) PWR of Kraftwerk Union design with four loops, each containing a U-tube steam generator (SG) andmore » a reactor cooling pump (RCP). The thermal-hydraulic code DRUFAN-02 was used for the transient calculations.« less
Mechanism of 'GSI oscillations' in electron capture by highly charged hydrogen-like atomic ions

We suggest a qualitative explanation of oscillations in electron capture decays of hydrogen-like {sup 140}Pr and {sup 142}Pm ions observed recently in an ion experimental storage ring (ESR) of Gesellschaft fuer Schwerionenforschung (GSI) mbH, Darmstadt, Germany. This explanation is based on the electron multiphoton Rabi oscillations between two Zeeman states of the hyperfine ground level with the total angular momentum F = 1/2. The Zeeman splitting is produced by a constant magnetic field in the ESR. Transitions between these states are produced by the second, sufficiently strong alternating magnetic field that approximates realistic fields in the GSI ESR. The Zeemanmore » splitting amounts to only about 10{sup -5} eV. This allows explaining the observed quantum beats with the period 7 s.« less
The Anatomische Gesellschaft and National Socialism: an analysis based on newly available archival material.

PubMed

Winkelmann, Andreas

2015-09-01

The newly available scientific estate of Heinrich von Eggeling (1869-1954), long-time secretary of the Anatomische Gesellschaft (AG), allows a more profound analysis of how this scientific association went through the period of the "Third Reich". At the first meeting under the new rulers in 1934, von Eggeling and Siegfried Mollier prevented their board colleague Martin Heidenhain from giving an introductory talk because they (not unjustly) feared anti-Jewish protests, but also because many anatomy professors, like other German scholars, were fervent nationalists who welcomed Hitler and largely accepted the expulsion of Jewish and other colleagues as 'inevitable' for national renewal. Many persecuted members nevertheless remained on the membership lists and the AG never officially introduced anti-Jewish bylaws. Eggeling and his like-minded colleagues successfully defended the international status of the AG, though not so much against the Nazi authorities but against a younger generation of anatomists who were willing to benefit from the new political situation and strived for their own German anatomical association. The available archival material suggests that the motivation of the established leading members of the AG to take this specific path was not rooted in opposition to the new rulers but rather in defence of their traditional status of reputed professors running a time-honoured, world leading society. This made international reputation an important guideline for many decisions. While they did ward off attempts by the younger generation to politicise the AG, their post-war calls for an apolitical science remain ambivalent, as their own stance had not always been apolitical.

Anatomische Gesellschaft from 1933 to 1950: a professional society under political strain - the Benninghoff papers.

PubMed

Hildebrandt, Sabine

2013-10-01

The Anatomische Gesellschaft (anatomical society, AG) was founded in Germany in 1886 as an international society and remains the main organizing body of German anatomists to this day. A previous study of the history of the AG during National Socialism (NS) was based on the published proceedings of the AG and drew the preliminary conclusion that the "AG did not follow the path of preemptive obedience toward the new rulers" in contrast to some other professional societies. However, it was noted that archival sources were needed to support this conclusion and to illustrate the decision process within the society. Such sources are now available in the estate papers of Alfred Benninghoff, a leading anatomist at the time. His correspondence supports the previous finding that the AG was able to maintain its international character, thereby enabling it to avoid the active exclusion of "non-Aryan" members. The papers also confirm that the AG did not defend its vulnerable members as valiantly as the official narrative suggests, a fact illustrated in a controversy surrounding Martin Heidenhain. The interactions and conflicts between the leaders of the AG can now be reconstructed, i.e. between the secretary of the AG Heinrich von Eggeling, Benninghoff and Hermann Stieve. The Benninghoff documents also refer to a meeting of a subsection of the AG in November 1942, at which a disturbing radicalization of some anatomists developed. Finally, the papers reflect the political realities for German professionals trying to re-establish their science in a country divided into four occupation zones. Copyright © 2013 Elsevier GmbH.

Posttest calculations of bundle quench test CORA-13 with ATHLET-CD

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bestele, J.; Trambauer, K.; Schubert, J.D.

Gesellschaft fuer Anlagen- und Reaktorsicherheit is developing, in cooperation with the Institut fuer Kernenergetik und Energiesysteme, Stuttgart, the system code Analysis of Thermalhydraulics of Leaks and Transients with Core Degradation (ATHLET-CD). The code consists of detailed models of the thermal hydraulics of the reactor coolant system. This thermo-fluid dynamics module is coupled with modules describing the early phase of the core degradation, like cladding deformation, oxidation and melt relocation, and the release and transport of fission products. The assessment of the code is being done by the analysis of separate effect tests, integral tests, and plant events. The code willmore » be applied to the verification of severe accident management procedures. The out-of-pile test CORA-13 was conducted by Forschungszentrum Karlsruhe in their CORA test facility. The test consisted of two phases, a heatup phase and a quench phase. At the beginning of the quench phase, a sharp peak in the hydrogen generation rate was observed. Both phases of the test have been calculated with the system code ATHLET-CD. Special efforts have been made to simulate the heat losses and the flow distribution in the test facility and the thermal hydraulics during the quench phase. In addition to previous calculations, the material relocation and the quench phase have been modeled. The temperature increase during the heatup phase, the starting time of the temperature escalation, and the maximum temperatures have been calculated correctly. At the beginning of the quench phase, an increased hydrogen generation rate has been calculated as measured in the experiment.« less

Cryogenic System for the New International Accelerator Facility for Research with Ions and Antiprotons at GSI

The Gesellschaft fuer Schwerionenforschung (GSI), Darmstadt, is planning an extension of the existing heavy ion accelerator. The new facilities will contain two synchrotrons, four storage rings and approximately 1.4 km of beam transport, requiring different types of magnets and cooling regimes. As the magnets for the synchrotrons have to be fast-ramped magnets, the cryogenic system heat loads will be dominated by the AC-losses of the magnets. Our approach is to adopt and modify existing magnet designs to achieve a short development time for the facility. The cryogenic system has to provide 7.5 kW at 4.4 K in the two-phase cooling regime, 3 kW at 0.4 MPa and 4.2 K in forced-flow cooling for the synchrotrons. The storage ring magnets will be placed in bath cryostats and require a refrigeration capacity of 5 kW at 4.5 K. As the project will be commissioned in several steps, an economic plan for the cryogenic infrastructure is needed, which will be sufficient for every phase of the build-up and allow experiments in some parts of the facilities as well as the testing of the components for the later parts of the facility.

Analyses of a 1:6-scale reinforced concrete containment model that will be tested to failure at Sandia National Laboratories in the spring of 1987 were conducted by the following organizations in the United States and Europe: Sandia National Laboratories (USA), Argonne National Laboratory (USA), Electric Power Research Institute (USA), Commissariat a L'Energie Atomique (France), HM Nuclear Installations Inspectorate (UK), Comitato Nazionale per la ricerca e per lo sviluppo dell'Energia Nucleare e delle Energie Alternative (Italy), UK Atomic Energy Authority, Safety and Reliability Directorate (UK), Gesellschaft fuer Reaktorsicherheit (FRG), Brookhaven National Laboratory (USA), and Central Electricity Generating Board (UK). Each organization wasmore » supplied with a standard information package, which included construction drawings and actual material properties for most of the materials used in the model. Each organization worked independently using their own analytical methods. This report includes descriptions of the various analytical approaches and pretest predictions submitted by each organization. Significant milestones that occur with increasing pressure, such as damage to the concrete (cracking and crushing) and yielding of the steel components, and the failure pressure (capacity) and failure mechanism are described. Analytical predictions for pressure histories of strain in the liner and rebar and displacements are compared at locations where experimental results will be available after the test. Thus, these predictions can be compared to one another and to experimental results after the test.« less

The thermal-hydraulic computer code ATHLET (Analysis of THermal-hydraulics of LEaks and Transients) is being developed by the Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) for the analysis of anticipated and abnormal plant transients, small and intermediate leaks as well as large breaks in light water reactors. The aim of the code development is to cover the whole spectrum of design basis and beyond design basis accidents (without core degradation) for PWRs and BWRs with only one code. The main code features are: advanced thermal-hydraulics; modular code architecture; separation between physical models and numerical methods; pre- and post-processing tools; portability. The codemore » has features that are of special interest for applications to small leaks and transients with accident management, e.g. initialization by a steady-state calculation, full-range drift-flux model, dynamic mixture level tracking. The General Control Simulation Module of ATHLET is a flexible tool for the simulation of the balance-of-plant and control systems including the various operator actions in the course of accident sequences with AM measures. The code development is accompained by a systematic and comprehensive validation program. A large number of integral experiments and separate effect tests, including the major International Standard Problems, have been calculated by GRS and by independent organizations. The ATHLET validation matrix is a well balanced set of integral and separate effects tests derived from the CSNI proposal emphasizing, however, the German combined ECC injection system which was investigated in the UPTF, PKL and LOBI test facilities.« less

Urinary tract infections (UTI) belong to the most frequent bacterial infections in outpatients. Increasing antibiotic resistance rates and a new appreciation of the epidemiological side effects of antibiotics ("collateral damage") have warranted an update of the guidelines on uncomplicated UTI as an S3 clinical guideline. The guideline was developed by the Deutsche Gesellschaft für Urologie (DGU) in collaboration with the Deutsche Gesellschaft für Allgemein- und Familienmedizin (DEGAM), Deutsche Gesellschaft für Gynäkologie und Geburtshilfe (DGGG), Deutsche Gesellschaft für Hygiene und Mikrobiologie (DGHM), Deutsche Gesellschaft für Infektiologie (DGI), Deutsche Gesellschaft für Nephrologie (DGfN), Paul-Ehrlich-Gesellschaft für Chemotherapie (PEG) and a patient representative. The systematic review of the literature on the topics of the guideline was performed for the time period of 1 January 1998 to 30 April 2008 in the databases of the Cochrane Library and MEDLINE. International guidelines of the years 1999-2007 were included. Uncomplicated UTI comprise uncomplicated cystitis and uncomplicated pyelonephritis. The leading uropathogen is Escherichia coli. The choice of the antibiotic substance follows the five primary aspects: (1) individual patient risk and antibiotic pretreatment; (2) bacterial spectrum and antibiotic susceptibility; (3) effectivity of the antimicrobial substance demonstrated in clinical studies; (4) epidemiological effects ("collateral damage"); and (5) adverse effects. If antibiotics such as trimethoprim/sulfamethoxazole or fluoroquinolones have previously been given, the risk for pathogens to become resistant against these substances is increased. Because of increasing resistance rates of E. coli against trimethoprim/sulfamethoxazole also in uncomplicated UTI, trimethoprim alone or in combination with sulfamethoxazole is no longer regarded as the first-line agent in the empiric treatment of uncomplicated cystitis, unless the regional

The Deutsche Gesellschaft für Urologie (German Urological Association), established in 1907, was a German-Austrian medical society in which Jewish physicians held important positions. When the Nazis seized power in 1933, the Austrian Hans Rubritius was president of the society. The non-German presidency and the exclusion of Jewish colleagues from the professional society and medical practice led to a halt of the society's activities. At the same time in the mid 1930s, German urologists founded the Gesellschaft Reichsdeutscher Urologen (Association of Reichs-German Urologists) whose members aligned themselves with Nazi health policies and in turn received professional and personal benefits.

Dick, Wolfgang R.; Hamel, Jürgen

This issue comprises talks presented 2000 September 18 at the colloquium ``International relations in astronomy'' it is supplemented by additional articles about this topic. The foundation of the international ``Vereinigte Astronomische Gesellschaft'', which took place in 1800 in Bremen, prompted us to investigate the development of astronomy in German-speaking regions, and its international relations during the 19th century. We investigate the activities of famous astronomers like W. Olbers, J.E. Bode, F.X. von Zach, J.H. Schroeter, H.C. Schumacher and K. Schwarzschild, as well as those of their less famous professional colleagues like J.G. Schrader and L. de Ball. The geographical spectrum extends from Bremen and Lilienthal over Kiel, Gotha and Dresden to Copenhagen, Vienna and Chile. Among the topics are: telescope construction, including telescopes made by Herschel, the rediscovery of the minor planet Ceres 1801/02, the Berlin ``Astronomisches Jahrbuch'', the foundation of the ``Astronomische Nachrichten'', the evolution from the ``Vereinigte Astronomische Gesellschaft'' to the present-day ``Astronomische Gesellschaft'', the research at the Kuffner Observatory in Vienna, the professionalization in astronomy, and the attempts of many countries to establish a southern observatory in Chile. A listing of astronomical monuments in Lilienthal and Bremen concludes the book. All papers are written in German with English abstracts.

Treatment of Juvenile Idiopathic Arthritis (JIA) has improved quality of life in children and adolescents with JIA. Standardisation of care offers the chance to improve the quality of care of those patients. New studies have been published after completion of our last treatment guideline (2007). An updated consensus process is mandatory. A systematic literature analysis in PUBMED (key words: juvenile idiopathic (rheumatoid) arthritis, therapy; limits: humans, published in the last 3 years, all child 0-18 years, clinical trial) revealed 17 relevant studies.

Duttge, G

2016-04-01

Modern intensive care medicine is faced with large challenges which are not solely caused by medical-technical progress, but above all by the demographic and value-related changes of society and its citizens. Thereby, three central problem areas are of particular interest: the fragile effectiveness of a patient's right to self-determination at the end of life, the uncertainties regarding the demarcation of futility, and the question of the influence of economic considerations (rationing) in view of the different levels for the allocation of duties and execution of duties. This article contains the revised version of the lecture from June 18, 2015 on the occasion of the 47th annual joint conference of DGIIN (Deutschen Gesellschaft für Internistische Intensivmedizin und Notfallmedizin) and ÖGIAIN (Österreichischen Gesellschaft für Internistische und Allgemeine Intensivmedizin und Notfallmedizin) on the general subject: "quality and humanity".

Nukleinsäure-Amplifikations-Techniken (NAT), wie die PCR, sind hochsensitiv sowie selektiv und stellen in der mikrobiologischen Diagnostik wertvolle Ergänzungen zur kulturellen Anzucht und Serologie dar. Sie bergen aber gerade bei formalinfixiertem und in Paraffin eingebettetem Gewebe ein Risiko für sowohl falsch negative als auch falsch positive Resultate, welches nicht immer richtig eingeschätzt wird. Daher haben Vertreter der Deutschen Gesellschaft für Hygiene und Mikrobiologie (DGHM) und der Deutschen Dermatologischen Gesellschaft (DDG) einen Konsensus in Form einer Übersichtsarbeit erarbeitet, wann eine NAT am Paraffinschnitt angezeigt und sinnvoll ist und welche Punkte dabei in der Präanalytik und Befundinterpretation beachtet werden müssen. Da bei Verdacht auf eine Infektion grundsätzlich Nativgewebe genutzt werden soll, ist die PCR am Paraffinschnitt ein Sonderfall, wenn beispielsweise bei erst nachträglichaufgekommenem Verdacht auf eine Infektion kein Nativmaterial zur Verfügung steht und nicht mehr gewonnen werden kann. Mögliche Indikationen sind der histologisch erhobene Verdacht auf eine Leishmaniose, eine Infektion durch Bartonellen oder Rickettsien, oder ein Ecthyma contagiosum. Nicht sinnvoll ist oder kritisch gesehen wird eine NAT am Paraffinschnitt zum Beispiel bei Infektionen mit Mykobakterien oder RNA-Viren. Die Konstellation für eine NAT aus Paraffingewebe sollte jeweils benannt werden, die erforderliche Prä-Analytik, die jeweiligen Grenzen des Verfahrens und die diagnostischen Alternativen bekannt sein. Der PCR-Befund sollte entsprechend kommentiert werden, um Fehleinschätzungen zu vermeiden. © 2018 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

2009-04-01

Purpose: To compare the biological effectiveness of 290 MeV/amu carbon-ion beams in Chiba, Japan and in Darmstadt, Germany, given that different methods for beam delivery are used for each. Methods and Materials: Murine small intestine and human salivary gland tumor (HSG) cells exponentially growing in vitro were irradiated with 6-cm width of spread-out Bragg peaks (SOBPs) adjusted to achieve nearly identical beam depth-dose profiles at the Heavy-Ion Medical Accelerator in Chiba, and the SchwerIonen Synchrotron in Darmstadt. Cell kill efficiencies of carbon ions were measured by colony formation for HSG cells and jejunum crypts survival in mice. Cobalt-60 {gamma} raysmore » were used as the reference radiation. Isoeffective doses at given survivals were used for relative biological effectiveness (RBE) calculations and interinstitutional comparisons. Results: Isoeffective D{sub 10} doses (mean {+-} standard deviation) of HSG cells ranged from 2.37 {+-} 0.14 Gy to 3.47 {+-} 0.19 Gy for Chiba and from 2.31 {+-} 0.11 Gy to 3.66 {+-} 0.17 Gy for Darmstadt. Isoeffective D{sub 10} doses of gut crypts after single doses ranged from 8.25 {+-} 0.17 Gy to 10.32 {+-} 0.14 Gy for Chiba and from 8.27 {+-} 0.10 Gy to 10.27 {+-} 0.27 Gy for Darmstadt, whereas isoeffective D{sub 30} doses after three fractionated doses were 9.89 {+-} 0.17 Gy through 13.70 {+-} 0.54 Gy and 10.14 {+-} 0.20 Gy through 13.30 {+-} 0.41 Gy for Chiba and Darmstadt, respectively. Overall difference of RBE between the two facilities was 0-5% or 3-7% for gut crypt survival or HSG cell kill, respectively. Conclusion: The carbon-ion beams at the National Institute of Radiological Sciences in Chiba, Japan and the Gesellschaft fuer Schwerionenforschung in Darmstadt, Germany are biologically identical after single and daily fractionated irradiation.« less

Treatment of Juvenile Idiopathic Arthritis (JIA) has improved quality of life in children and adolescents suffering from JIA. However, it varies considerably from caregiver to caregiver. Therefore a standardisation of care on the basis of consensus treatment recommendations offers the chance to further improve the quality of care for children and adolescents with JIA. We aimed to establish an interdisciplinary, evidence-based treatment guideline for JIA based on the existing guideline from 2005. We did a systematic literature analysis in PUBMED with the key words "juvenile idiopathic (rheumatoid) arthritis" and "therapy". As limits in PUBMED we used: humans, published in the last 3 years, all child 0-18 years, clinical trial. Studies relating to diagnosis of JIA, Uveitis, vaccination, transition and rofexocibe were excluded. Authors of the 2005 guideline and representatives nominated by different societies were invited to attend the consensus conferences which were hosted by a professional moderator. Following societies were invited: Berufsverband der Kinder- und Jugendärzte (BVKJ), Deutsche Gesellschaft für Kinder- und Jugendmedizin (DGKJ), Deutsche Gesellschaft für Rheumatologie (DGRh), Deutsche Ophthalmologische Gesellschaft (DOG), Deutsche Rheuma-Liga Bundesverband, Verein zur Förderung und Unterstützung rheumatologisch erkrankter Kinder und deren Eltern, Vereinigung für Kinderorthopädie, Zentraler Verband der Physiotherapeuten und Krankengymnasten (ZVK).

After the Second World War the development of medical mycology in Germany had taken a very different course in the east and west parts depending on the political division. In this respect our contribution deals with the situation in the former German Democratic Republic. Efficient mycological centres were founded step by step almost in all medical universities on the basis of the mycological laboratories in dermatological hospitals competent for diagnostic work, but also for teaching and scientific research. In this context biologists were the main stay of mycology, they finally were integrated to the same degree in the universities like physicians. The effectiveness of the Gesellschaft für Medizinische Mykologie der DDR (GMM), its board of directors and its working groups as well as the topics of human and animal mycology during this period are described. Especially the merger of the GMM with the Deutschsprachige Mykologische Gesellschaft after the reunification of Germany without problems and the kind co-operation of Prof. Dr. Johannes Müller during this procedure are emphasized.

Linking social change and developmental change: shifting pathways of human development.

PubMed

Greenfield, Patricia M

2009-03-01

P. M. Greenfield's new theory of social change and human development aims to show how changing sociodemographic ecologies alter cultural values and learning environments and thereby shift developmental pathways. Worldwide sociodemographic trends include movement from rural residence, informal education at home, subsistence economy, and low-technology environments to urban residence, formal schooling, commerce, and high-technology environments. The former ecology is summarized by the German term Gemeinschaft ("community") and the latter by the German term Gesellschaft ("society"; Tönnies, 1887/1957). A review of empirical research demonstrates that, through adaptive processes, movement of any ecological variable in a Gesellschaft direction shifts cultural values in an individualistic direction and developmental pathways toward more independent social behavior and more abstract cognition--to give a few examples of the myriad behaviors that respond to these sociodemographic changes. In contrast, the (much less frequent) movement of any ecological variable in a Gemeinschaft direction is predicted to move cultural values and developmental pathways in the opposite direction. In conclusion, sociocultural environments are not static either in the developed or the developing world and therefore must be treated dynamically in developmental research.

Prof. Kohn (1867-1959) was the head of the Institute of Histology at the Medical Faculty of German University in Prague for 26 years. In 2007 we commemorated his 140th birthday, and 2009 we will remember the 50th anniversary of his death. He entered the history of medicine by discovery of nature and origin of parathyroid glands and by pioneer research into chromaffin cells and sympathetic paraganglia. Kohn's papers on the pituitary, interstitial cells of testes, and ovaries are also related to endocrinology. All his studies are based on descriptive and comparative histological and embryological observations. Kohn was twice the dean of German Medical Faculty, and a member or honorary member of many important scientific societies. He was repeatedly nominated for Nobel Prize for physiology and medicine. For his Jewish origin he was expelled from Deutsche Gesellschaft der Wissenschaften und Künste für die Tschechoslowakische Republik in 1939 and transported to Terezin ghetto in 1943. After the war he lived in Prague. On the occasion of his 90th birthday he was elected honorary president of Anatomische Gesellschaft and awarded by the Czechoslovak Order of Labour. Alfred Kohn died in 1959. He was one of the outstanding personalities that Prague gave to the world of science.

The German Diagnosis-Related Groups (DRG) System was further developed into its 2007 version. For orthopedic and trauma surgery, significant changes were made in terms of the coding of diagnoses and medical procedures, as well as in the DRG structure itself. The German Societies for Trauma Surgery and for Orthopedics and Orthopedic Surgery (Deutsch Gesellschaft für Unfallchirurgie, DGU; and Deutsche Gesellschaft für Orthopädie und Orthopädische Chirurgie, DGOOC) once again cooperated constructively with the German DRG Institute InEK. Among other innovations, new International Classification of Diseases (ICD) codes for second-degree burns were implemented. Procedure codes for joint operations, endoprosthetic-surgery and spine surgery were restructured. Furthermore, a specific code for septic surgery was introduced in 2007. In addition, the DRG structure was improved. Case allocation of patients with more than one significant operation was established. Further DRG subdivisions were established according to the patients age and the Patient Clinical Complexity Level (PCCL). DRG developments for 2007 have improved appropriate case allocation, but once again increased the system's complexity. Clinicians need an ever growing amount of specific coding know-how. Still, further adjustments to the German DRG system are required to allow for a correct allocation of cases and funds.

Within the scope of 'Nuclear Security of Radioactive Sources', the German government implemented the modernization of Ukrainian State Production Company's transport and storage facility for radioactive sources (TSF) in Kiev. The overall management of optimizing the physical protection of the storage facility (including the construction of a hot cell for handling the radioactive sources) is currently carried out by the German Federal Foreign Office (AA). AA jointly have assigned Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) mbH, Germany's leading expert institution in the area of nuclear safety and waste management, to implement the project and to ensure transparency by financial andmore » technical monitoring. Sealed radioactive sources are widely used in industry, medicine and research. Their life cycle starts with the production and finally ends with the interim/long-term storage of the disused sources. In Ukraine, IZOTOP is responsible for all radioactive sources throughout their life cycle. IZOTOP's transport and storage facility (TSF) is the only Ukrainian storage facility for factory-fresh radioactive sources up to an activity of about 1 million Ci (3.7 1016 Bq). The TSF is specially designed for the storage and handling of radioactive sources. Storage began in 1968, and is licensed by the Ukrainian state authorities. Beside the outdated state of TSF's physical protection and the vulnerability of the facility linked with it, the lack of a hot cell for handling and repacking radioactive sources on the site itself represents an additional potential hazard. The project, financed by the German Federal Foreign Office, aims to significantly improve the security of radioactive sources during their storage and handling at the TSF site. Main tasks of the project are a) the modernization of the physical protection of the TSF itself in order to prevent any unauthorized access to radioactive sources as well as b) the construction of a hot cell to reduce the

2005-02-01

Superconducting melt-textured bulk (RE)BCO large grain materials are one of the most promising materials for power applications of high temperature superconductivity at the liquid nitrogen temperature range. Industrial applications are expected in high-speed low-loss magnetic bearings for flywheel energy storage devices, high-dynamic high-torque electric reluctance motors, and MAGLEV transportation systems. The material has high magnetic field trapping capability and therefore a new class of high-field superconducting permanent magnets will soon appear. However, there is still the need to improve the magnetic and mechanical material properties, as well as to increase the single domain size. This special issue contains papers concerning these topics presented at the International Workshop on the Processing and Applications of Superconducting (RE)BCO Large Grain Materials. The workshop was held on the 30 June-2 July 2003 in Jena, Germany, and was organized by the Institut fuer Physikalische Hochtechnologie, Jena. It was the fourth in the series of PASREG workshops after Cambridge, UK (1997), Morioka, Japan (1999), and Seattle, USA (2001). Sixty two contributions were presented at the workshop, 38 oral presentations and 24 poster presentations. This special issue contains 42 papers. The editors are grateful for the support of many colleagues who reviewed the manuscripts to guarantee their high technical quality. The editors also wish to thank Doris Litzkendorf and Tobias Habisreuther from Institut fuer Physikalische Hochtechnologie, Jena, for their assistance with the organization and handling of the manuscripts. Many thanks to the workshop co-chairman Gernot Krabbes from Leibniz-Institut fuer Festkoerper und Werkstoffforschung, Dresden, for hosting the workshop participants in Dresden.

For the calculation of the parasite resistance of an airplane, a knowledge of the resistance of the individual structural and accessory parts is necessary. The most reliable basis for this is given by tests with actual airplane parts at airspeeds which occur in practice. The data given here relate to the landing gear of a Siemanms-Schuckert DI airplane; the landing gear of a 'Luftfahrzeug-Gesellschaft' airplane (type Roland Dlla); landing gear of a 'Flugzeugbau Friedrichshafen' G airplane; a machine gun, and the exhaust manifold of a 269 HP engine.

[German neurology and neurologists during the Third Reich: Preconditions and general framework before and after 1933].

PubMed

Martin, M; Karenberg, A; Fangerau, H

2016-08-01

This article focuses on the institutional development of neurology in Germany up to the rise to power of the National Socialists and the radical sociopolitical changes after 1933. A wide range of scattered secondary literature was assessed and evaluated. Additionally, some original sources are literally quoted and interpreted according to the context. Since the end of the nineteenth century a complicated process of separation from internal medicine and psychiatry led to the formation of a self-conscious discipline of neurology. The first generation of German neurologists succeeded in founding the German Journal for Neurology ("Deutsche Zeitschrift für Nervenheilkunde") in 1890 and their own neurological association, the Society of German Neurologists ("Gesellschaft Deutscher Nervenärzte", GDN) in 1907. On an international scale, however, the institutional implementation of neurology with only a small number of chairs and few neurology departments remained more than modest. The ambitions for autonomy ended 2 years after the change of power in 1933. Regulatory interventions by the government and psychiatric interests led to the fusion of the GDN with the psychiatric specialist society, the new association being called the Society of German Neurologists and Psychiatrists ("Gesellschaft Deutscher Neurologen und Psychiater", GDNP) in 1935. In this group psychiatrists dominated the discourse. The expulsion, imprisonment and murder of physicians declared as non-Aryan or Jewish along with the forced consolidation ("Gleichschaltung") at the universities prompted profound changes in medical and academic life. It remains an ongoing challenge of neurological historical research to measure the impact of this upheaval on the few neurology departments in hospitals and private practices.

Levels in 223Th populated by the α decay of 227U were investigated using α -γ decay spectroscopy. The 227U isotope was produced in the fusion-evaporation reaction 22Ne +208Pb at the velocity filter separator for heavy-ion reaction products at Gesellschaft für Schwerionenforschung in Darmstadt (Germany). Several new excited levels and γ transitions were identified in 223Th . An improved α -decay scheme of 227U was suggested. The experimental α -decay energy spectrum of 227U was compared with the Monte Carlo simulation performed using the toolkit geant4.

Bromodomain and extra-terminal domain (BET) inhibition has emerged recently as a potential therapeutic target for the treatment of many human disorders such as atherosclerosis, inflammatory disorders, chronic obstructive pulmonary disease (COPD), some viral infections, and cancer. Since the discovery of the two potent inhibitors, I-BET762 and JQ1, different research groups have used different techniques to develop novel potent and selective inhibitors. In this review, we will be concerned with the trials that used fragment-based drug discovery (FBDD) approaches to discover or optimize BET inhibitors, also showing fragments that can be further optimized in future projects to reach novel potent BET inhibitors. © 2017 Deutsche Pharmazeutische Gesellschaft.

Meanwhile, not only scientific progress in imaging techniques but also in other fields such as neuropsychology has necessitated a revision, which is presented here. In the mean time, the handling of guidelines has been systematised in Germany so that a registration with the Cooperation of German Medical Learned Societies is applied for and publication in the German Guideline Registry is expected. © Georg Thieme Verlag KG Stuttgart · New York.
Der Einfluss der Digitalisierung auf die Organisation eines Unternehmens

Walter, Wolfram M.

Die Digitalisierung schreitet mit großen Schritten voran. Dies wirkt sich nicht nur auf die Gesellschaft im Grundsatz, sondern auch auf das Verhalten der Kunden aus. Neue Kommunikationswege beschleunigen die Interaktion zwischen Unternehmen und Verbraucher. Im Vergleich mit großen Internetfirmen werden etablierte Dienstleistungsunternehmen - vom Energieversorger bis zu Versicherungen - stark unter Druck gesetzt, sich noch intensiver mit dem Kundenservice auseinanderzusetzen. Dies wird nur möglich sein, wenn sich die Organisationen entsprechend positionieren und sich frühzeitig auf die Veränderungen einstellen. Hieraus ergeben sich mehr Chancen als Risiken, zumal es nicht nur neue Prozesse, sondern auch neue Berufsbilder geben wird.

Perhaps, pilgrimage sites are one of the oldest examples of controlled place branding, but they are still an interesting teaching tool for this subject because they are characterized by lower complexity and functionality compared to cities and regions. They are also smaller in size and they usually occupy very specific positions of popular piety. This makes the transferability of the branding concept easier than in other urban or rurality areas. Against this background, this essay examines the question how popular piety can still contribute to place branding of pilgrimages sites.
Measurement of Quantum Phase-Slips in Josephson Junction Chains

Quantum phase-slip dynamics in Josephson junction chains could provide the basis for the realization of a new type of topologically protected qubit or for the implementation of a new current standard. I will present measurements of the effect of quantum phase-slips on the ground state of a Josephson junction chain. We can tune in situ the strength of the phase-slips. These phase-slips are the result of fluctuations induced by the finite charging energy of each junction in the chain. Our measurements demonstrate that a Josephson junction chain under phase bias constraint behaves in a collective way. I will also show evidence of coherent phase-slip interference, the so called Aharonov-Casher effect. This phenomenon is the dual of the well known Aharonov-Bohm interference.

Hemodynamic monitoring and adequate volume-therapy, as well as the treatment with positive inotropic drugs and vasopressors are the basic principles of the postoperative intensive care treatment of patient after cardiothoracic surgery. The goal of these S3 guidelines is to evaluate the recommendations in regard to evidence based medicine and to define therapy goals for monitoring and therapy. In context with the clinical situation the evaluation of the different hemodynamic parameters allows the development of a therapeutic concept and the definition of goal criteria to evaluate the effect of treatment. Up to now there are only guidelines for subareas of postoperative treatment of cardiothoracic surgical patients, like the use of a pulmonary artery catheter or the transesophageal echocardiography. The German Society for Thoracic and Cardiovascular Surgery (Deutsche Gesellschaft für Thorax-, Herz- und Gefässchirurgie, DGTHG) and the German Society for Anaesthesiology and Intensive Care Medicine (Deutsche Gesellschaft für Anästhesiologie und lntensivmedizin, DGAI) made an approach to ensure and improve the quality of the postoperative intensive care medicine after cardiothoracic surgery by the development of S3 consensus-based treatment guidelines. Goal of this guideline is to assess the available monitoring methods with regard to indication, procedures, predication, limits, contraindications and risks for use. The differentiated therapy of volume-replacement, positive inotropic support and vasoactive drugs, the therapy with vasodilatators, inodilatators and calcium sensitizers and the use of intra-aortic balloon pumps will also be addressed. The guideline has been developed following the recommendations for the development of guidelines by the Association of the Scientific Medical Societies in Germany (AWMF).

PubMed

Martin, M; Fangerau, H; Karenberg, A

2016-08-01

The article discusses the consequences for neurology as a discipline which resulted from neurologists' participation in the crimes committed under National Socialism (NS). Chronologically, the current literature distinguishes mainly four overlapping stages: (1) a first phase was characterized by legal persecution and "denazification", which was also the time of the Nuremberg doctors' trial in which no neurologists were on trial. A detailed documentation of the trial for the German medical profession was published by Alexander Mitscherlich. (2) In the subsequent practice of wide amnestying and reintegration of former Nazi followers during the 1950s, neurologists were no exception as its elite continued in their positions. The year 1953 was the year of the Lisbon scandal, when chiefly Dutch representatives protested against the participation of Julius Hallervorden in the International Congress of Neurology. The newly founded societies, the German Society for Neurology (Deutsche Gesellschaft für Neurologie, DGN) and the German Society for Psychiatry and Neurology (Deutsche Gesellschaft für Psychiatrie und Neurologie, DGPN), unanimously supported their member. (3) The next period was characterized by a nascent criticism of the prevailing attitude of covering up the crimes committed by physicians during the Nazi period. The discovery of incriminating brain sections at various Max Planck Institutes brought neurology to the focus of the debate. (4) Since the 1980s and 1990s historians (of medicine) have been systematically examining medicine's Nazi past in a professional way, which resulted in a noticeable increase of knowledge. Additionally, a new generation of scholars provoked a change of mind insofar as they recognized medicine's responsibility for the crimes committed between 1933 and 1945. We expect that future historical research will further elucidate the history of neurology during the NS regime and have consequences for our current understanding of research

The origins of the North German expeditions to observe the total solar eclipse of August 18, 1868, are outlined. The incentive was made by politician and science writer Aaron Bernstein, the financing was provided by the North German Federation, and the project was handled by members of the Astronomische Gesellschaft. The astronomical expeditions to Mulwar in India and Aden in South Arabia are summarized, the following archaeological expedition to upper Egypt is also considered. The activities of the participating scientists, also with respect to the preparation of popular accounts, are described. Finally, the impact of these expeditions on the planning of the large-scale project to observe the Venus transits of 1874 and 1882 is investigated.

The discovery and synthesis of new tyrosine-based inhibitors of DNA gyrase B (GyrB), which target its ATPase subunit, is reported. Twenty-four compounds were synthesized and evaluated for activity against DNA gyrase and DNA topoisomerase IV. The antibacterial properties of selected GyrB inhibitors were demonstrated by their activity against Staphylococcus aureus and Enterococcus faecalis in the low micromolar range. The most promising compounds, 8a and 13e, inhibited Escherichia coli and S. aureus GyrB with IC 50 values of 40 and 30 µM. The same compound also inhibited the growth of S. aureus and E. faecalis with minimal inhibitory concentrations (MIC 90 ) of 14 and 28 µg/mL, respectively. © 2017 Deutsche Pharmazeutische Gesellschaft.

Topical photodynamic therapy (PDT) is a highly effective and safe treatment method for actinic keratoses with an excellent cosmetic outcome and is commonly used for the therapy of large areas of photodamaged skin with multiple clinically manifest and subclinical lesions. However, the major drawback of photodynamic therapy is the pain experienced during the treatment that can be intense and sometimes even intolerable for patients, requiring interruption or termination of the process. Several strategies for controlling pain during photodynamic therapy have been studied but few effective methods are currently available. Therefore, this review puts the spotlight on predictors on pain intensity and aspects of pain management during photodynamic therapy. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

The history of the German Association for Psychiatry and--after its merger with the Society of German Neurologists in 1935--the Society of German Neurologists and Psychiatrists (Gesellschaft deutscher Neurologen und Psychiater, GDNP) during the period of National Socialism has been subjected to only rudimentary research. The conventionally accepted idea that two independent professional associations were "coordinated" from above and turned into the extended arm of Nazi genetic health policy (Erbgesundheitspolitik) against their will must be reconsidered. This paper asks how the relationship between the GDNP and the Nazi state can be described adequately. Psychiatry and neurology as practice and science, and the biopolicy development dictatorship of National Socialism functioned, so the basic thesis, as "resources for each other" (Mitchell Ash).

Experiments with accelerated heavy ions may contribute to the understanding of biological radiation action. After outlining the theoretical background experiments are described which were carried out at the UNILAC-machine (Gesellschaft für Schwerionenforschung, Darmstadt, Germany) where ions up to uranium can be accelerated to maximal specific energies of 10 MeV/u. Yeast cells served as biological test systems with the synthesis of ribosomal RNA (r-RNA), colony-forming ability and mutation induction as experimental endpoints. A relationship between action and energy deposition by individual particles can be demonstrated for the inhibition of r-RNA synthesis, in other cases the ion energy plays also an important role indicating that the interaction of δ-electrons from different particles contributes significantly to the biological effect.

In 1994 and 1998 reports on staffing levels in medical radiation physics for radiation therapy were published by the "Deutsche Gesellschaft für Medizinische Physik" (DGMP, German Society for Medical Physics). Because of the technical and methodological progress, changes in recommended qualifications of staff and new governmental regulations, it was necessary to establish new staffing levels. The data were derived from a new survey in clinics. Some of the previously established results from the old reports were adapted to the new conditions by conversion.The staffing requirements were normalized to main components as in the earlier reports resulting in a simple method for calculation of staffing levels. The results were compared with the requirements in the "Richtlinie Strahlenschutz in der Medizin" (guidelines on radiation protection in medicine) and showed satisfactory agreement.

Pathogenetische Hauptfaktoren (und ihre klinischen Korrelate) sind gesteigerte Talgproduktion (Seborrhoe), follikuläre Hyperkeratose (Komedonen) und perifollikuläre Entzündungsvorgänge (Papulopusteln). Die Krankheit wird von endogenen (Androgene, IGF-1, neuroendokrine Faktoren) und exogenen (Propionibacterium acnes, Diät, mechanische Irritation, Inhaltsstoffe medizinischer oder kosmetischer Externa) Einflüssen moduliert. Akne geht mit zum Teil hoher Morbidität einher und kann bereits bei leichter Ausprägung eine erhebliche Verschlechterung der Lebensqualität bewirken. Zu Therapie stehen wirksame topische und systemische Behandlungsverfahren zur Verfügung.

In the first, historical part the most important programs of "Medical Enlightenment", are pointed out, beginning with Leibniz, followed by the public health movement of the 18th century, up to the time of Immanuel Kant. Based on this historical background several concepts of a "Medical Culture" are analysed in detail, for instance the "Theorie einer Medizinal-Ordnung" by Johann Benjamin Ehrhard (1800), the "Medicinische Reform" by Rudolf Virchow (1848) and the programs of the "Gesellschaft Deutscher Naturforscher und Arzte" (about 1850-1890), the latter bearing both scientific and political character. Following the historical part, the question is raised whether "Enlightenment" is limited by medicine and whether medicine is able to provide a program for individual health education resulting in a more cultivated style of private life, and lastly how this might be realized.

Acne vulgaris is a common skin condition which can have a negative impact on a patient's quality of life. A survey was distributed among students at tertiary institutions. Data was collected on participants' own rating of acne grade and how acne affected their social life. A clinician on-site graded the participants' acne. Of the 429 students who participated in the survey, 59.8 % felt embarrassed or self-conscious because of their acne. There was a low but statistically significant correlation (Spearman's Correlation Coefficient = 0.471, p < 0.001) between participants' and clinicians' grading of acne. Acne vulgaris causes a considerable amount of psychosocial stress. There are unfounded beliefs surrounding acne and unawareness of treatment options available. © 2015 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.
Time domain analysis of coherent terahertz synchrotron radiation

The time structure of coherent terahertz synchrotron radiation at the electron storage ring of the Berliner Elektronensynchrotron und Speicherring Gesellschaft has been analyzed with a fast superconducting hot-electron bolometer. The emission from a single bunch of electrons was found to last ˜1500ps at frequencies around 0.4THz, which is much longer than the length of an electron bunch in the time domain (˜5ps). It is suggested that this is caused by multiple reflections at the walls of the beam line. The quadratic increase of the power with the number of electrons in the bunch as predicted for coherent synchrotron radiation and the transition from stable to bursting radiation were determined from a single storage ring fill pattern of bunches with different populations.

We describe a non-invasive technique to obtain blood samples from incubating birds without trapping and handling. A larval instar of the blood-sucking bug Dipetalogaster maximus (Heteroptera) was put in a hollowed artificial egg which was placed in a common tern Sterna hirundo) nest. A gauze-covered hole in the egg allowed the bug to draw blood from the brood patch of breeding adults. We successfully collected 68 blood samples of sufficient amount (median=187 ??l). The daily success rate was highest during the early breeding season and averaged 34% for all trials. We could not detect any visible response by the incubating bird to the sting of the bug. This technique allows for non-invasive blood collection from bird species of various sizes without disturbance. ?? Dt. Ornithologen-Gesellschaft e.V. 2005.

Stars in their late stage of evolution, such as horizontal branch stars, are still largely unexplored for planets. We detected a planetary companion around HIP 13044, a very metal-poor star on the red horizontal branch, on the basis of radial velocity observations with a high-resolution spectrograph at the 2.2-meter Max-Planck Gesellschaft-European Southern Observatory telescope. The star’s periodic radial velocity variation of P = 16.2 days caused by the planet can be distinguished from the periods of the stellar activity indicators. The minimum mass of the planet is 1.25 times the mass of Jupiter and its orbital semimajor axis is 0.116 astronomical units. Because HIP 13044 belongs to a group of stars that have been accreted from a disrupted satellite galaxy of the Milky Way, the planet most likely has an extragalactic origin.

With the purpose of expanding the structural variety of chemical compounds available as pharmacological tools for the treatment of Alzheimer's disease, we synthesized and evaluated a novel series of indole-benzoxazinones (Family I) and benzoxazine-arylpiperazine derivatives (Family II) for potential human acetylcholinesterase (hAChE) inhibitory properties. The most active compounds 7a and 7d demonstrated effective inhibitory profiles with K i values of 20.3 ± 0.9 μM and 20.2 ± 0.9 μM, respectively. Kinetic inhibition assays showed non-competitive inhibition of AChE by the tested compounds. According to our docking studies, the most active compounds from both series (Families I and II) showed a binding mode similar to donepezil and interact with the same residues. © 2018 Deutsche Pharmazeutische Gesellschaft.
Implosion of multilayered cylindrical targets driven by intense heavy ion beams.

2002-11-01

An analytical model for the implosion of a multilayered cylindrical target driven by an intense heavy ion beam has been developed. The target is composed of a cylinder of frozen hydrogen or deuterium, which is enclosed in a thick shell of solid lead. This target has been designed for future high-energy-density matter experiments to be carried out at the Gesellschaft für Schwerionenforschung, Darmstadt. The model describes the implosion dynamics including the motion of the incident shock and the first reflected shock and allows for calculation of the physical conditions of the hydrogen at stagnation. The model predicts that the conditions of the compressed hydrogen are not sensitive to significant variations in target and beam parameters. These predictions are confirmed by one-dimensional numerical simulations and thus allow for a robust target design.

Proteins play a vital role within the human body by regulating various functions and even serving as structural constituent of many body parts. In this context, protein-based therapeutics have attracted a lot of attention in the last few decades as potential treatment of different diseases. Due to the steadily increasing interest in protein-based therapeutics, different dosage forms were investigated for delivering such complex macromolecules to the human body. Here, electrospun fibers hold a great potential for embedding proteins without structural damage and for controlled release of the protein for therapeutic applications. This review provides a comprehensive overview of the current state of protein-based carrier systems using electrospun fibers, with special emphasis on discussing their potential and key challenges in developing such therapeutic strategies, along with a prospective view of anticipated future directions. © 2017 Deutsche Pharmazeutische Gesellschaft.

2016-07-01

The current issue of AN is Volume 28 of the Reviews in Modern Astronomy and presents the Karl Schwarzschild Award Lecture, the Ludwig Bierman n Award Lecture and the Doctoral Thesis Award Lecture given at the 88th Annual International Scientific Meeting of the Astronomische Gesellschaft held in Kiel, Germany, September 14-18, 2015. It was the fifth time that Kiel hosted a meeting of the AG, the first one was in 1887. In 2015 the fall meeting was a part of the celebrations of the 350th anniversary of the Christiana Albertina University Kiel in 1665. For astronomers around the globe, the astrophysical group is well known for the Kieler Schule and its fundamental contributions to the physics of stellar atmospheres. Based on the work by Albrecht Unsöld during his tenure of 41 years as active researcher and lecturer (and many more after becoming emeritus), the quantitative analysis of stellar atmospheres and the reliable determination of chemical abundances is nowadays a cornerstone of modern astrophysics. Even more, it is of ground-laying importance for the whole field, from the characterization of exoplanets and their host stars to the properties of galaxies at cosmic dawn. The meeting was guided by the theme "From the First Quasars to Life-Bearing Planets -- From Accretion Physics to Astrobiology". The meeting was attended by almost 300 participants from around the world. The Karl Schwarzschild Medal 2015 of the Astronomische Gesellschaft was awarded to Professor Immo Appenzeller, Heidelberg. His lecture with the title "Astronomical technology -- the past and the future" opened the meeting. The talk presented by the Ludwig Biermann Award winner 2015, Dr. Ivan Minchev, Potsdam, dealt with the topic "Constraining the Milky Way assembly history with Galactic Archaeology". The Doctoral Thesis Award 2015 was awarded to Dr. Cornelia Müller (Würzburg). In her lecture she discussed the subject "Multiwavelength and parsec-scale properties of extragalactic Jets". The AG
Between Autonomy and Accommodation:The German Physical Society during the Third Reich

2005-09-01

I first sketch the history of the German Physical Society (Deutsche Physikalische Gesellschaft,DPG) from its founding by six young Berlin scientists as the Physical Society of Berlin (Physikalische Gesellschaft zu Berlin) in 1845, through its renaming as the DPG in 1899 and its rise to prominence by the beginning of the 1930s. I then turn to the history of the DPG during the Third Reich, which can be divided into two periods, from the transfer of power in Germany to the Nazis in 1933 to 1940, and from 1941 to 1945. During the first period, Johannes Stark (1874 1957), one of the leaders of the “German Physics” (Deutsche Physik) movement, attempted to gain election as the Chairman of the DPG in September 1933 but was repulsed. A period of relative autonomy of the DPG from Nazi ideology and policies ensued, which gradually was transformed into one of accommodation, until at the end of the 1938, Peter Debye (1884 1966), then Chairman of the DPG, bowed to governmental demands and Nazi activists in the DPG, introduced Nazi principles, and strongly advised the Jewish members of the DPG to withdraw from it. Debye left Germany in early 1940, and after a transitional period in which Jonathan Zenneck (1871 1959) served as Acting Chairman, Carl Ramsauer (1879 1955) was elected Chairman of the DPG in December 1940, thus opening the second period, the Ramsauer era, which lasted from 1941 until the end of the war in 1945. Ramsauer oversaw the self-coordination (Selbstgleichschaltung) of the DPG to the Nazi regime, and as an industrial physicist he led the DPG to establish ever more alliances with powerful figures in the military-industrial complex of Nazi Germany, which worked to the advantage both of Ramsauer and the DPG and to that of the Nazi regime during the course of the war. Finally, as the military defeat of Germany loomed, Ramsauer took steps aimed at insuring the survival of German physics in the postwar period. After the war, he masked the wartime activities of

The aim of this study was to examine postural control in patients with chronic non-specific low back pain (CNRS). Furthermore the influence of visual information (eyes open versus eyes closed) was analyzed. A total of 8 patients with CNRS and 12 healthy control subjects were examined. Surface electromyography (SEMG) recordings were made from 5 trunk and 5 lower limb muscles as well as one hip muscle during application of distal lateral perturbation. Healthy controls (mean ± standard deviation: 96.42±64.77 µV) showed a significantly higher maximum amplitude of the gluteus medius muscle in comparison to patients with CNRS (56.29±39.63 µV). Furthermore activation of several lower limb muscles was found to be dependent on visual information. Patients showed an altered reflex response of the gluteus medius muscle which could be associated with reduced hip stability. © Deutsche Gesellschaft zum Studium des Schmerzes

While neonatal skin physiology has been thoroughly examined using non-invasive techniques in recent years, only few systematic studies and review articles addressing the histopathology of neonatal skin have been published thus far. In most cases, histopathological findings of dermatoses in neonatal skin do not significantly differ from those seen in adult skin. Nevertheless, a comprehensive knowledge of embryonic and fetal skin development as well as the microanatomical structure of neonatal skin can contribute to a better understanding of various dermatoses of infancy. In the first part of this review article, we present the histopathological features of such skin diseases, which, though generally rare, almost exclusively appear during the first weeks of life due to distinctive structural and functional features of neonatal skin. The second part is dedicated to classic dermatoses of infancy and their histopathological features. © 2015 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.
Does body size influence nest attendance? A comparison of Ross's geese (Chen rossii) and the larger, sympatric lesser snow geese (C. caerulescens caerulescens)

The body-size hypothesis predicts that nest attendance is positively related to body size among waterfowl and that recess duration is inversely related to body size. Several physiological and behavioral characteristics of Ross's geese (Chen rossii) suggest that females of this species should maintain high nest attendance despite their relatively small body size. Accordingly, we used 8-mm films to compare the incubation behavior of Ross's geese to that of the larger, closely-related lesser snow geese (C. caerulescens caerulescens; hereafter, snow geese) nesting sympatrically at Karrak lake, Nunavut, Canada in 1993. We found that nest attendance averaged 99% for both species. Our results offer no support for the body-size hypothesis. We suggest that temperature requirements of embryos in relation to short incubation duration and a low foraging efficiency of females select for high nest attendance in both snow geese and Ross's geese. ??

The diagnostic workup of cutaneous fungal infections is traditionally based on microscopic KOH preparations as well as culturing of the causative organism from sample material. Another possible option is the detection of fungal elements by dermatohistology. If performed correctly, these methods are generally suitable for the diagnosis of mycoses. However, the advent of personalized medicine and the tasks arising therefrom require new procedures marked by simplicity, specificity, and swiftness. The additional use of DNA-based molecular techniques further enhances sensitivity and diagnostic specificity, and reduces the diagnostic interval to 24-48 hours, compared to weeks required for conventional mycological methods. Given the steady evolution in the field of personalized medicine, simple analytical PCR-based systems are conceivable, which allow for instant diagnosis of dermatophytes in the dermatology office (point-of-care tests). © 2016 Deutsche Dermatologische Gesellschaft (DDG).

The Kaiser Wilhelm Institute for Anthropology, Human Genetics and Eugenics in Berlin-Dahlem was the centre of scientific racism in Nazi Germany. Its bad history culminated in a research project to analyse the molecular basis of racial differences in the susceptibility to various infectious diseases such as tuberculosis. Josef Mengele, a former postdoc of the director of the institute, Otmar von Verschuer, collected blood samples and other material in Auschwitz from families and twins of Jews and Gypsies. The blood samples were analysed by Günther Hillmann in the Berlin laboratory of Nobel Prize winner Adolf Butenandt. Butenandt had just moved to Tübingen. The project was paid for by the Deutsche Forschungsgemeinschaft. Butenandt, Hillmann and von Verschuer made scientific careers in the Federal Republic. To the present day this past has not been acknowledged by the Max-Planck-Gesellschaft as part of its history.

Gausemeier, Bernd

2010-01-01

During the Third Reich, the biological institutes of the Kaiser Wilhelm Society (KWG, Kaiser-Wilhelm-Gesellschaft) underwent a substantial reorganization and modernization. This paper discusses the development of projects in the fields of biochemical genetics, virus research, radiation genetics, and plant genetics that were initiated in those years. These cases exemplify, on the one hand, the political conditions for biological research in the Nazi state. They highlight how leading scientists advanced their projects by building close ties with politicians and science-funding organizations and companies. On the other hand, the study examines how the contents of research were shaped by, and how they contributed to, the aims and needs of the political economy of the Nazi system. This paper therefore aims not only to highlight basic aspects of scientific development under Nazism, but also to provide general insights into the structure of the Third Reich and the dynamics of its war economy.

An analytical procedure for the simultaneous determination in human serum of 43 common drugs of abuse and their metabolites belonging to the different chemical and toxicological classes of amphetamines, benzodiazepines, dibenzazepines, cocaine, lysergic acid diethylamide, opioids, phencyclidine, tricyclic antidepressants, and zolpidem, using 33 deuterated standards, is presented. The sample treatment was developed to be a very simple protein precipitation and filtration. All analyses were performed with a high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry in positive ionization mode. All analytes were calibrated up to 550 μg/L. The limit of detection ranged from 0.6 ng/mL (EDDP) to 13.7 ng/mL (flunitrazepam). The method has been validated according to the guidelines of the Gesellschaft für Toxikologische und Forensische Chemie, using three multiple reaction mode (MRM) transitions and retention time for positive compound identification, instead of two MRMs, in anticipation of the new guidelines for January 2011.
The Theory of Industrial Society and Cultural Schemata: Does the "Cultural Myth of Stigma" Underlie the WHO Schizophrenia Paradox?

PubMed

2015-11-01

The WHO's International Studies of Schizophrenia conclude that schizophrenia may have a more benign course in "developing" societies than in the West. The authors focus on this finding's most common corollary: cultural schemata are shaped by the transition from agrarian to industrial society. Developing societies are viewed as traditional, gemeinschaft cultures lacking the stigmatizing beliefs about persons with mental illness held in modern, gesellschaft cultures of developed societies. The Stigma in Global Context-Mental Health Study formalized the cultural myth of public stigma (CMPS) with propositions linking level of development to intolerant, exclusionary, and individualistic attitudes. In 17 countries, the authors find no support for the corollary; where support is found, the findings are opposite expectations, with developed societies reporting lower stigma levels. Reconceptualizing of the cultural landscape on more specific dimensions also produces null or contrary findings. This correction to nostalgic myths of cultural context in developing societies thwarts misguided treatment, policy, and stigma-reduction efforts.

Successful allergen-specific immunotherapy (SIT) induces complex immunologic chan-ges resulting in reduced allergic inflammatory reactions. SIT has long-term effects in mild forms of inhalant allergies and is effective even when standard pharmacotherapy fails. Moreover, the risk to develop additional allergic sensitizations and the development of asthma is significantly reduced in children with allergic rhinitis. SIT is the treatment of choice in patients with systemic reactions to hymenoptera venoms. Although the exact effector mechanisms of SIT still have to be clarified, the most probable effect is a modulation of regulatory T cells associated with a switch of allergen-specific B-cells towards IgG4 production. The critical point to insure efficacy and safety is the selection of patients and allergens, task best performed by a specialist trained in allergology. Further details are available in the position papers of the German allergy societies - DGAI(Deutsche Gesellschaft fiir Allergologie und Klinische Immunologie) and ADA (Arzte-verband Deutscher Allergologen) - which can be found at www.dgaki.de.

ONCOBASE provides better surveillance concerning all therapeutic procedures including cytostatic drugs and supportive therapies. 3. ONCOBASE allows the generation of medical letters which include all drugs and supportive therapies delivered. 4. Since ONCOBASE is a database program, all informations concerning the patients are registered. These include cumulative drug doses, information on side effects, blood cell kinetics after previous therapies, kinetics of tumor markers and results of further examinations. 5. ONCOBASE permits rapid data exchange with other hospital networks using the communication data record governed by the "Arbeitskreis für EDV der deutschen Gesellschaft für Hämatoonkologie".

The author was set the task of relating from his memories the beginning of modern virus research in Germany. This research has, since 1936, essentially taken place in the Kaiser-Wilhelm/Max-Planck-Society and in 1954 led to the founding of the Max-Planck-Institute for Virus Research in Tübingen, an institute which to the present day owes its scientific reputation in considerable part to the activity of Werner Schäfer. Since the author personally experienced and participated in the Institute's development from 1936-1954, his remarks are predominantly influenced by personal recollections, which have been sharpended by a renewed study of old records in the 'Library and Archive of the History of the Max-Planck-Gesellschaft', Berlin-Dahlem.
Germany-US Nuclear Theory Exchange Program for QCD Studies of Hadrons & Nuclei 'GAUSTEQ'

Dudek, Jozef; Melnitchouk, Wally

GAUSTEQ was a Germany-U.S. exchange program in nuclear theory whose purpose was to focus research efforts on QCD studies of hadrons and nuclei, centered around the current and future research programs of Jefferson Lab and the Gesellschaft fur Schwerionenforschung (GSI) in Germany. GAUSTEQ provided travel support for theoretical physicists at US institutions conducting collaborative research with physicists in Germany. GSI (with its Darmstadt and Helmholtz Institute Mainz braches) served as the German “hub” for visits of U.S. physicists, while Jefferson Lab served as the corresponding “hub” for visits of German physicists visiting U.S. institutions through the reciprocal GUSTEHP (German-US Theorymore » Exchange in Hadron Physics) program. GAUSTEQ was funded by the Office of Nuclear Physics of the U.S. Department of Energy, under Contract No.DE-SC0006758 and officially managed through Old Dominion University in Norfolk, Virginia. The program ran between 2011 and 2015.« less

The history of medical and veterinary mycology in general has been reviewed in the excellent monography by G.C. Ainsworth (1905-1998) published in 1986. Here, we will focus on German-speaking mycology and their outstanding personalities. We will start with the early years when medical mycology was in its infancy. Microscopy was a most valuable tool for the identification of fungi followed by cultivation and staining methods. Human pathologies became linked to fungi. After World War I, medical mycology flourished as an integral part of dermatology at universities and in private institutes. The development was interrupted by World War II, which divided Germany. In both parts of Germany, medical mycology had to be re-established. After re-unification the two different medical societies joined together. The development of DMyK (Deutschsprachigen Mykologischen Gesellschaft - Mykologie) is illustrated. Important personalities and some of their achievements are mentioned. Mycology has attracted other fields of medicine including internal medicine, pediatrics, microbiology, and veterinary medicine.
Estimation of Dry Fracture Weakness, Porosity, and Fluid Modulus Using Observable Seismic Reflection Data in a Gas-Bearing Reservoir

Fracture detection and fluid identification are important tasks for a fractured reservoir characterization. Our goal is to demonstrate a direct approach to utilize azimuthal seismic data to estimate fluid bulk modulus, porosity, and dry fracture weaknesses, which decreases the uncertainty of fluid identification. Combining Gassmann's (Vier. der Natur. Gesellschaft Zürich 96:1-23, 1951) equations and linear-slip model, we first establish new simplified expressions of stiffness parameters for a gas-bearing saturated fractured rock with low porosity and small fracture density, and then we derive a novel PP-wave reflection coefficient in terms of dry background rock properties (P-wave and S-wave moduli, and density), fracture (dry fracture weaknesses), porosity, and fluid (fluid bulk modulus). A Bayesian Markov chain Monte Carlo nonlinear inversion method is proposed to estimate fluid bulk modulus, porosity, and fracture weaknesses directly from azimuthal seismic data. The inversion method yields reasonable estimates in the case of synthetic data containing a moderate noise and stable results on real data.
On the phylogenetic position of the scrub-birds (Passeriformes: Menurae: Atrichornithidae) of Australia

Evolutionary relationships of the scrub-birds Atrichornis were investigated using complete sequences of the recombination-activating gene RAG-1 and the proto-oncogene c-mos for two individuals of the noisy scrub-bird Atrichornis clamosus. Phylogenetic analysis revealed that Atrichornis was sister to the genus Menura (the lyrebirds) and that these two genera (the Menurae) were sister to the rest of the oscine passerines. A sister relationship between Atrichornis and Menura supports the traditional view, based on morphology and DNA hybridization, that these taxa are closely related. Similarly, a sister relationship with the remaining oscine passerines agrees with the morphological distinctiveness of Atrichornis and Menura, although this result contradicts conclusions based on DNA hybridization studies. Although Atrichornis is very well known morphologically, previous conclusions regarding its relationships were hampered by a lack of comparative knowledge of other passerines, making concurrence of the sequence data of particular significance. ??

The 14th volume of the Acta Historica Astronomiae is the Proceedings of a Colloquium International Relationships in Astronomy (in German) organised by the History of Astronomy Section of the Astronomische Gesellschaft held on September 18 in Lilienthal, Germany. The book contains 13 articles on astronomical topics covering the 19th and 20th centuries. The first paper is by Guenther Oestmann and deals with contemporary assessments of Johann Hieronymus Schroeter's (1745-1816) astronomical works and with later judgements of the scientific importance and significance of his observations as seen by astronomers and historians. This report is complemented by a second article on Schroeter's 25-ft reflector in Lilienthal near Bremen. To this end, author Felix Luehning has constructed a scale model of the telescope, and shows how the building of a model brings a deeper understanding of function and handling of this instrument. This brings us to a third paper on telescope building in Lilienthal: Hans-Joachim Leue describes the cooperation of Johann Hieronymus Schroeter and Johann Gottlieb Schrader in developing a white reflecting metal alloy for use as telescope mirror. The fourth article, by Klaus Schillinger, describes on the basis of archival documents the aquisition history of the Herschel telescopes, including telescope quality check, repair and building. Memorial sites referring to Wilhelm Olbers, Johann Hieronymus Schroeter, Friedrich Wilhelm Bessel and Carl Friedrich Gauss are described by Arno Langkavel in two walks outlined in the very last paper of this book. Peter Brosche, in the fifth paper, discusses the rediscovery of Ceres in December1801, a discovery that was the result of the combined efforts of a theoretician (Gauss) and an observer (Zach). Juergen Hamel's paper is based on previously unused archival sources and discusses the outstanding role played by H. C. Schumacher (1780-1850, editor of the Astronomische Nachrichten) in the communication between
Space Radar Image of Kilauea Volcano, Hawaii

This three-dimensional image of the volcano Kilauea was generated based on interferometric fringes derived from two X-band Synthetic Aperture Radar data takes on April 13, 1994 and October 4, 1994. The altitude lines are based on quantitative interpolation of the topographic fringes. The level difference between neighboring altitude lines is 20 meters (66 feet). The ground area covers 12 kilometers by 4 kilometers (7.5 miles by 2.5 miles). The altitude difference in the image is about 500 meters (1,640 feet). The volcano is located around 19.58 degrees north latitude and 155.55 degrees west longitude. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory. X-SAR was developed by the Dornier and Alenia Spazio companies for the German space agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian space agency, Agenzia Spaziale Italiana (ASI), with the Deutsche Forschungsanstalt fuer Luft und Raumfahrt e.V.(DLR), the major partner in science, operations and data processing of X-SAR. The Instituto Ricerca Elettromagnetismo Componenti Elettronici (IRECE) at the University of Naples was a partner in the interferometry analysis.

To get a general idea of the actual staffing level situation in medical radiation physics in 1999 a survey was carried out by the task-group "Personalbedarf" of Deutsche Gesellschaft für Medizinische Physik (DGMP) among all DGMP-members who are active in this field. Main components for equipment and activities are defined in Report 8 and 10 of DGMP for staffing requirements in medical radiation physics. 322 forms were sent out, 173 of them have been evaluated. From the answers regarding equipment and activities numbers for staff are calculated by the methods given in Report 8 and 10 for this spot check target and compared with effective staffing levels. The data of the spot check are then extrapolated on total Germany. The result is a calculated deficit of 865 medical physicists for the whole physics staff, 166 of them in radiation therapy. From the age distribution of DGMP-members and the calculated deficit resulted a training capacity of about 100 medical physicists at all per year (19 in radiation therapy) if the deficit shall be cut back in 10 years.
New developments in occupational dermatology.

Occupational skin diseases according to BK No. 5101 - "severe or recurrent skin diseases which have forced the person to discontinue all occupational activities that caused or could cause the development, worsening, or recurrence of the disease" - is the most commonly reported notifiable occupational diseases in Germany. Following the optimization of measures of primary, secondary, and tertiary prevention, today most individuals affected are able to continue their profession. With the revision of the German ordinance on occupational diseases (BKV) in January 2015, skin cancer caused by UV irradiation was added to the list of occupational diseases. The new occupational disease (BK) 5103 is defined as "squamous cell carcinoma or multiple actinic keratoses of the skin caused by natural UV irradiation". In this context, "multiple" signifies the occurrence of either more than five individual actinic keratosis lesions over the course of 12 months or the presence of field cancerization of > 4 cm(2) . In the following review, important aspects of this new occupational disease will be highlighted and discussed. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.
Quantensprung Digitalisierung - Energiewirtschaft im 21. Jahrhundert

Thyen, Elmar

Die Energiewende wird ohne eine umfassende Digitalisierung der Energiewirtschaft Stückwerk bleiben. Die historisch gewachsene, aus hunderten fossilen Großkraftwerken getriebene Energieversorgung hat sich durch den Zubau von mehr als einer Millionen dezentraler Erzeugungseinheiten innerhalb der vergangenen 15 Jahren radikal verändert. Zum Ausgleich von Last und Erzeugung, aber auch zum Aufbau neuer Geschäftsfelder ist die digitale Technik unverzichtbar. Ihre Möglichkeiten scheinen nahezu unbegrenzt, ihre Rolle wird in einer zukünftig nahezu vollständig elektrifizierten Gesellschaft zunehmend wichtiger werden. Neue Anbieter drängen auf den Markt und setzen die traditionelle Energiewirtschaft unter Druck. Energieversorger, die sich dem Wandel nicht stellen, drohen den Anschluss zu verpassen. Noch werden Verbundunternehmen und Stadtwerke von weitreichenden regulatorischen Vorgaben geschützt. Beispiele aus anderen Branchen zeigen aber, dass die Digitalisierung im Stande ist, regulatorische Mechanismen außer Kraft zu setzen. Zugleich verhindert die enge Regulierung und ein falsch verstandener Datenschutzbegriff in Deutschland die Entwicklung neuer Geschäftsmodelle, die energie- und volkswirtschaftlich sinnvoll wären.
Kohn-Sham Band Structure Benchmark Including Spin-Orbit Coupling for 2D and 3D Solids

Huhn, William; Blum, Volker

2015-03-01

Accurate electronic band structures serve as a primary indicator of the suitability of a material for a given application, e.g., as electronic or catalytic materials. Computed band structures, however, are subject to a host of approximations, some of which are more obvious (e.g., the treatment of the exchange-correlation of self-energy) and others less obvious (e.g., the treatment of core, semicore, or valence electrons, handling of relativistic effects, or the accuracy of the underlying basis set used). We here provide a set of accurate Kohn-Sham band structure benchmarks, using the numeric atom-centered all-electron electronic structure code FHI-aims combined with the ``traditional'' PBE functional and the hybrid HSE functional, to calculate core, valence, and low-lying conduction bands of a set of 2D and 3D materials. Benchmarks are provided with and without effects of spin-orbit coupling, using quasi-degenerate perturbation theory to predict spin-orbit splittings.

Obwohl bislang für die Rosazea keine kurative Therapie besteht, können verschiedene Optionen zur Behandlung der Symptome und zur Vorbeugung von Exazerbationen empfohlen werden. Neben Selbsthilfemaßnahme wie der Vermeidung von Triggerfaktoren und einer geeigneten Hautpflege sollte das Rosazea-Management bei Patienten mit erythematöser und leichter bis schwerer papulopustulöser Rosazea die Anwendung topischer Präparate als First-Line-Therapie umfassen. Da Überlappungen der charakteristischen Rosazea-Symptome im klinischen Alltag die Regel sind, sollte die medikamentöse Therapie auf die individuellen Symptome zugeschnitten werden; auch eine Kombinationstherapie kann erforderlich sein. Zu den für die Behandlung der Hauptsymptome der Rosazea zugelassenen Wirkstoffen gehören Brimonidin gegen das Erythem sowie Ivermectin, Metronidazol oder Azelainsäure gegen entzündliche Läsionen. Ihre Wirksamkeit wurde in zahlreichen validen, gut kontrollierten Studien belegt. Darüber hinaus existieren verschiedene nicht zugelassene topische Behandlungsmöglichkeiten, deren Wirksamkeit und Sicherheit noch in größeren, kontrollierten Studien zu untersuchen ist. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

High-definition optical coherence tomography - an aid to clinical practice and research in dermatology.

At present, beyond clinical assessment, the diagnosis of skin diseases is primarily made histologically. However, skin biopsies have many disadvantages, including pain, scarring, risk of infection, and sampling error. With recent advances in skin imaging technology, the clinical use of imaging methods for the practical management of skin diseases has become an option. The in vivo high-definition optical coherence tomography (HD-OCT) has recently been developed and commercialized (Skintell; Agfa, Belgium). Compared with conventional OCT, it has a higher resolution; compared with reflectance confocal microscopy, it has a shorter time for image acquisition as well as a greater penetration depth and a larger field of view. HD-OCT is promising but much work is still required to develop it from a research tool to a valuable adjunct for the noninvasive diagnosis of skin lesions. Substantial work has been done to identify HD-OCT features in various diseases but interpretation can be time-consuming and tedious. Projects aimed at automating these processes and improving image quality are currently under way. © 2015 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

This X-band image of the volcano Kilauea was taken on October 4, 1994, by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar. The area shown is about 9 kilometers by 13 kilometers (5.5 miles by 8 miles) and is centered at about 19.58 degrees north latitude and 155.55 degrees west longitude. This image and a similar image taken during the first flight of the radar instrument on April 13, 1994 were combined to produce the topographic information by means of an interferometric process. This is a process by which radar data acquired on different passes of the space shuttle is overlaid to obtain elevation information. Three additional images are provided showing an overlay of radar data with interferometric fringes; a three-dimensional image based on altitude lines; and, finally, a topographic view of the region.

To obtain an overview of the actual staffing levels in Medical Radiation Physics, a survey was carried out in 1999 by the task-group "Staffing requirements" of the Deutsche Gesellschaft für Medizinische Physik (DGMP; German Society of Medical Physics) among all DGMP members active in this field. The main components for equipment and activities are defined as in Report 8 and 10 of the DGMP for staffing requirements in Medical Radiation Physics. The survey focused on these main components. Of 322 forms sent out, 173 answers could be evaluated. From the answers regarding equipment and activities, theoretical staff requirements were calculated on the basis of this spot-check target and compared with the effective staffing levels documented in the survey. The spot-check data were then extrapolated to the whole Germany. The calculation revealed a deficit of 72% for the whole physics staff and of 58% for the number of physicists. Considering the age distribution of the DGMP members and the calculated staffing deficit, a training need was calculated of approximately 100 medical physicists per year in Germany, provided that the goal is set of cutting back the deficit in 10 years.

Tick-borne encephalitis virus (TBEV), a member of the genus Flavivirus, is the leading cause of arboviral neuroinfections in Europe. Only a few classes of the nucleoside and non-nucleoside inhibitors were investigated against TBEV reproduction. Paving the way to previously unexplored areas of anti-TBEV chemical space, we assessed the inhibition of TBEV reproduction in the plaque reduction assay by various compounds derived from cyanothioacetamide and cyanoselenoacetamide. Compounds from seven classes, including 4-(alkylthio)-2-aryl-3-azaspiro[5.5]undec-4-ene-1,1,5-tricarbonitriles, 3-arylamino-2-(selenazol-2-yl)acrylonitriles, ethyl 6-(alkylseleno)-5-cyano-2-oxo-1,2-dihydropyridine-3-carboxylates, 6-(alkylseleno)-2-oxo-1,4,5,6-tetrahydropyridine-3-carbonitriles, 2-(alkylseleno)-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carbonitriles, 8-selenoxo-3,5,7,11-tetraazatricyclo[7.3.1.0 2,7 ]tridec-2-ene-1,9-dicarbonitriles, and selenolo[2,3-b]quinolines, inhibited TBEV reproduction with EC 50 values in the micromolar range while showing moderate cytotoxicity and no inhibition of enterovirus reproduction. Thus, new scaffolds with promising anti-TBEV activity were found. © 2018 Deutsche Pharmazeutische Gesellschaft.

The Gesellschaft für Schwerionenforschung (GSI) is planning a significant expansion of its accelerator facilities. Compared to the present GSI facility, a factor of 100 in primary beam intensities and up to a factor of 10,000 in secondary radioactive beam intensities are key technical goals of the proposal. The second branch of the so-called Facility for Antiproton and Ion Research (FAIR) is the production of antiprotons and their storage in rings and traps. The facility will provide beam energies a factor of approximately 15 higher than presently available at the GSI for all ions, from protons to uranium. The shielding design of the synchrotron SIS 100/300 is shown exemplarily by using Monte Carlo calculations with the FLUKA code. The experimental area serving the investigation of compressed baryonic matter is analysed in the same way. In addition, a dose comparison is made for an experimental area operated with medium energy heavy-ion beams. Here, Monte Carlo calculations are performed by using either heavy-ion primary particles or proton beams with intensities scaled by the mass number of the corresponding heavy-ion beam.

Several ionization potentials (IPs) of security relevant substances were determined with single photon ionization time of flight mass spectrometry (SPI-TOFMS) using monochromatized synchrotron radiation from the "Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung" (BESSY). In detail, the IPs of nine explosives and related compounds, seven narcotics and narcotics precursors, and one chemical warfare agent (CWA) precursor were determined, whereas six IPs already known from the literature were verified correctly. From seven other substances, including one CWA precursor, the IP could not be determined as the molecule ion peak could not be detected. For these substances the appearance energy (AE) of a main fragment was determined. The analyzed security-relevant substances showed IPs significantly below the IPs of common matrix compounds such as nitrogen and oxygen. Therefore, it is possible to find photon energies in between, whereby the molecules of interest can be detected with SPI in very low concentrations due to the shielding of the matrix. All determined IPs except the one of the explosive EGDN were below 10.5 eV. Hence, laser-generated 118 nm photons can be applied for detecting almost all security-relevant substances by, e.g., SPI-TOFMS.
Organizational responses to a changing aid environment: the German Agency for Technical Cooperation (GTZ).

As a major European donor, German government development assistance faces a series of challenges. Recent political changes have raised expectations for demonstrable health outcomes as a result of German development assistance; there has been a deepened commitment to collaboration with other bilateral and multilateral donors; and partner countries are increasingly open to new approaches to development. German development assistance also reflects a new ethos of partnership and the shift to programmatic and sector based development approaches. At the same time, its particular organizational structure and administrative framework highlight the extent of structural and systems reforms required of donors by changing development relationships, and the tensions created in responding to these. This paper examines organizational changes within the German Agency for Technical Cooperation (Deutsche Gesellschaft für Technische, Zusammenarbeit) (GTZ), aimed at increasing its Regional, Sectoral, Managerial and Process competence as they affect health and related sectors. These include the decentralization of GTZ, the trend to integration of projects, the increasing focus on policy and health systems reform, increased inter-sectoral collaboration, changes in recruitment and training, new perspectives in planning and evaluation and the introduction of a quality management programme.

This paper is intended to celebrate the 120th anniversary of the discovery of X-rays. X-rays (Roentgen-rays) were discovered on the 8th ofNovember, 1895 by the German physicist Wilhelm Conrad Roentgen. Fifty days after the discovery of X-ray, on December 28, 1895. Wilhelm Conrad Roentgen published a paper about the discovery of X-rays - "On a new kind of rays" (Wilhelm Conrad Roentgen: Ober eine neue Art von Strahlen. In: Sitzungsberichte der Wurzburger Physik.-Medic.- Gesellschaft. 1895.). Therefore, the date of 28th ofDecember, 1895 was taken as the date of X-rays discovery. This paper describes the work of Wilhelm Conrad Roentgen, Nikola Tesla, Mihajlo Pupin and Maria Sklodowska-Curie about the nature of X-rays . The fantastic four - Wilhelm Conrad Roentgen, NikolaTesla, Mihajlo ldvorski Pupin and Maria Sklodowska-Curie set the foundation of radiology with their discovery and study of X-rays. Five years after the discovery of X-rays, in 1900, Dr Avram Vinaver had the first X-ray machine installed in abac, in Serbia at the time when many developed countries did not have an X-ray machine and thus set the foundation of radiology in Serbia.
Delayed immediate-type hypersensitivity to red meat and innards: current insights into a novel disease entity.

The development of component-resolved diagnostics instead of whole extracts has brought about major advances in recent years. Particularly remarkable has been the identification of new disease entities based on the detection of IgE antibodies against specific individual components. In this context, delayed immediate-type hypersensitivity to red meat and innards plays a key role. This disorder is more common in German-speaking countries and likely still underdiagnosed. Affected individuals exhibit delayed type I reactions following the consumption of red meat or innards (responses to the latter are more rapid). All patients have IgE antibodies against the oligosaccharide galactose-α-1,3-galactose - alpha-gal. Those affected also have to avoid alpha-gal-containing drugs such as cetuximab or gelatin-containing colloidal solutions. Also referred to as alpha-gal syndrome, this condition is unique in that it is characterized by type I hypersensitivity to a sugar instead of a protein. Given that many patients have a history of recurrent episodes of acute urticaria or angioedema, dermatologists should be familiar with the alpha-gal syndrome. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

The Architectural and Instrumental Heritage of the Strasbourg University Observatory

Davoigneau, Jean

When, in 1872, Alsace was handed over to Germany, Empperor Wilhelm I decided to make Strasbourg the showcase of his empire, and in particular to build a prestigious university and an observatory. The construction of the observatory was entrusted to the astronomer August Winnecke (1835-1897), former director of the Pulkovo observatory, and to the Baumeister Hermann Eggert. Begun in 1876, the work was completed in 1880. The astronomical instruments, ordered from German makers, were installed during the winter of 1880-1881, and the observatory was inaugurated on September 22, 1881 at the general assembly of the Astronomische Gesellschaft, the international association of astronomers, whose secretary was Winnecke. Marking the south-eastern extremity of the ‘imperial axis’, the architecture of the university observatory harmonizes perfectly with the new German city built on the former French parade grounds. The astronomical heritage operation conducted at the beginning of the present decade provides a richly docurnented and illustrated inventory of both the architecture and instruments of this institution. This work has also highlighted the unique quality of the collection of instruments, befitting the long and complex history of this institution.

A total of 218 breast cancer centers, with 274 operating sites, have been certified since 2003 in accordance with the criteria set out by the German Cancer Society (Deutsche Krebsgesellschaft) and the German Society for Breast Diseases (Deutsche Gesellschaft für Senologie). Most of these centers are located in Germany, but centers in Austria, Switzerland, and Italy have also been certified. This paper presents the results for quality indicators (QIs) from 2009 to 2012, based on data from 195,342 primary breast cancer patients, in order to illustrate the development and progress of these centers. Descriptive results on interdisciplinary collaboration (6 QIs), guideline adherence (15 QIs), and specialist expertise (7 QIs) are reported over time. Fulfillment of the certification requirements was high and remained relatively stable over time, with the extent of variation between sites declining. Sites that do not reach the target values are asked to comment on the discrepancies, and their comments, as well as the QI results, are used by centers and auditors during an on-site auditing process and to constantly revise the QIs set out by the guideline and the certification commission.

The Theory of Industrial Society and Cultural Schemata: Does the “Cultural Myth of Stigma” Underlie the WHO Schizophrenia Paradox?

The “Better Prognosis Hypothesis” stems from World Health Organization studies known as the International Studies of Schizophrenia (ISoS). Despite greater availability and sophistication of treatment options in the West, schizophrenia appears to have a more benign course and better outcomes in “developing” societies. We focus on this finding's most common corollary: a simplified version of sociological notions of cultural reality shaped by the transition from agrarian to industrial society. Developing societies are viewed as traditional, gemeinschaft cultures that neither develop nor endorse stigmatizing attitudes and beliefs about persons with mental illness that exist in modern, gesellschaft cultures of developed societies. Using the Stigma in Global Context-Mental Health Study (SGC-MHS), we formalize the “Cultural Myth of Stigma,” propositions linking level of development to intolerant, exclusionary, and individualistic attitudes. In 17 countries, we find no support for the corollary. Where significant associations are documented, the findings are opposite expectations: the public in more developed societies reports lower stigma levels. Extensions to reconceptualizations of the cultural landscape also reveal null or contrary findings. This correction to nostalgic myths of cultural context in developing societies thwarts misguided treatment, policy, and stigma-reduction efforts. PMID:26640277
The diversity-biomass-productivity relationships in grassland management and restoration

Guo, Q.

2007-01-01

Diversity, biomass, and productivity, the three key community/ecosystem variables, are interrelated and pose reciprocal influences on each other. The relationships among the three variables have been a central focus in ecology and formed two schools of fundamentally different nature with two related applications: (1) management - how biomass manipulation (e.g., grazing, burning) affects diversity and productivity, and (2) restoration - how diversity manipulation (e.g., seeding, planting) affects biomass and productivity. In the past, the two apparently related aspects have been studied intensively but separately in basic research and the reciprocal effects of the three variables and applied aspects have not been jointly addressed. In most cases, optimal management often involves regulating biomass so that high diversity and productivity or other preferred habitat characteristics can be achieved and maintained, while restoration usually involves planting/seeding a certain number and/or combination of native species so that the native structure and function of the habitat can be restored and degraded ecosystems can recover faster. This article attempts to unify these two schools and discusses the significance and implications of the diversity-biomass-productivity relationships in practice, with particular emphasis on grassland ecosystems. ?? 2006 Gesellschaft fu??r O??kologie.
Therapeutic management of cutaneous and genital warts.

PubMed

Ockenfels, Hans Michael

2016-09-01

During their lifetime, at least 10 % of the population will be infected by human papillomaviruses (HPV), clinically characterized by the formation of cutaneous or genital warts. Although warts are ubiquitous, there are no defined treatments. Especially in the first six months, warts frequently resolve without therapeutic intervention. This complicates the interpretation of study data, given that many studies do not differentiate between newly infected patients and those with infections that have persisted for a long time. Similarly, most studies do not take location, size, and thickness of lesions into account, either. The objective of the present review article is to analyze the study data currently available, taking into consideration both subtypes and locations - factors exceedingly crucial in clinical practice. In particular, the distinction between new-onset and chronic recalcitrant warts is reflected in a therapeutic algorithm. In the case of genital warts, the algorithm is more clearly determined by the extent of the area affected rather than the longevity of lesions. In immunocompetent individuals, any therapeutic intervention must be aimed at achieving complete resolution. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

The Bundesamt fuer Kartographie und Geodaesie (BKG) will provide a major contribution to the improvement and maintenance of the global reference frames: ICRF (International Celestial Reference Frame), ITRF (International Terrestrial Reference Frame) with the operation of TIGO (Transportable Integrated Geodetic Observatory). TIGO is designed as a transportable geodetic observatory which consists of all relevant geodetic space techniques for a fundamental station (including VLBI, SLR, GPS). The transportability of the observatory enables to fill up gaps in the International Space Geodetic Network and to optimize the contribution to the global reference frames. TIGO should operate for a period of 2 to 3 years (at minimum) at one location. BKG is looking for a cooperation with countries willing to contribute to the ITRF and to support the operation of TIGO.

The measurements were performed using the CASAC (Center for Astrochemical Studies Absorption Cell) spectrometer at the Max-Planck-Institut fuer extraterrestrische Physik. Full details of the experimental apparatus can be found in Bizzocchi et al. (2017A&A...602A..34B). The instrument employs the frequency modulation technique in the mm and submm range and is equipped with a glow discharge cell for production of unstable species. Measurements were carried out at room temperature to avoid condensation of the precursors. Dithioformic acid was produced by a 40mA DC discharge (~0.8kV) from a 1:1 mixture of CS2 and H2, diluted in Ar buffer gas. The total pressure in the cell was 20-30mTorr (27-40ubar). (4 data files).

This paper presents first results of the project 'Technologien fuer die intelligente Kontrolle von Raumfahrzeugen' (TIKON). The TIKON objective was the demonstration of feasibility and profit of the application of artificial intelligence in the space business. For that purpose a prototype system has been developed and implemented for the operation support of the Roentgen Satellite (ROSAT), a scientific spacecraft designed to perform the first all-sky survey with a high-resolution X-ray telescope and to investigate the emission of specific celestial sources. The prototype integrates a scheduler and a diagnosis tool both based on artificial intelligence techniques. The user interface is menu driven and provides synoptic displays for the visualization of the system status. The prototype has been used and tested in parallel to an already existing operational system.

The 13th General Conference of the Condensed Matter Division of the European Physical Society was held in conjunction with the Frühjahrstagung des Arbeitskreises Festkörperphysik der Deutschen Physikalischen Gesellschaft from March 29 till April 2, 1993, in Regensburg. The programme comprised 3,134 contributions : 8 Plenary Talks, 171 Invited Talks, 1,480 Contributed Talks, 1,441 Poster Presentations, 1 Public Evening Talk and 33 Exhibitors Reports. The abstracts have been published as Europhysics Conference Abstracts, Volume 17A/Verhandlungen der Deutschen Physikalischen Gesellschaft 5/1993. The table (see PDF file) shows the distribution of the Plenary and Invited Speakers as well as of the participants according to countries within and outside of Europe. The conference was the largest meeting of physicists held in Germany to date. It was a manifestation of the enormous scientific activity in both basic and applied research in the fields of Condensed Matter Physics in Europe. Most of the research work, which was presented at the conference, was done by young physicists. They represent a large human capital in Europe. Most of the senior physicists and many of our young colleagues maintain scientific cooperations, and also personal friendships, which are and which have been almost independent of national barriers over the past three decades. The latter is to a large extent due to the European Physical Society which always cultivated these contacts, especially between the eastern and western parts of Europe. We would like to express our sincere thanks to the members of the Programme Committee. By their intensive work, which was free from national interests, a scientific programme was prepared, which covered the entire field of Condensed Matter Physics. About 70% of the Plenary and Invited Speakers came from 20 different foreign countries and about 30% from Germany. The meeting therefore has been a truly European Conference.

We are pleased to present the proceedings from the Astronomy at High Angular Resolution 2011: The central kiloparsec in galactic nuclei conference. The conference took place in the Physikzentrum of the Deutsche Physikalische Gesellschaft (DPG), Bad Honnef, Germany, from 28 August to 2 September 2011. It was the second conference of this kind, following the Astronomy at High Angular Resolution conference held in Bad Honnef, three years earlier in 2008. The main objective of the conference was to frame the discussion of the broad range of physical processes that occur in the central 100pc of galactic nuclei. In most cases, this domain is difficult to probe through observations. This is mainly because of the lack of angular resolution, the brightness of the central engine and possible obscurations through dust and gas, which play together in the central regions of host galaxies of galactic nuclei within a broad range of activity. The presence of large amounts of molecular and atomic (both neutral and ionized) gas, dust and central engines with outflows and jets implies that the conditions for star formation in these regions are very special, and probably different from those in the disks of host galaxies. Numerous presentations covering a broad range of topics, both theoretical and experimental, those related to research on Active Galactic Nuclei and on a wide range of observed wavelengths were submitted to the Scientific Organizing Committee. Presentations have been grouped into six sessions: The nuclei of active galaxies The Galactic Center The immediate environment of Super Massive Black Holes The physics of nuclear jets and the interaction of the interstellar medium The central 100pc of the nuclear environment Star formation in that region The editors thank all participants of the AHAR 2011 conference for their enthusiasm and their numerous and vivid contributions to this conference.

Jung's evolving views of Nazi Germany: from 1936 to the end of World War II.

Schoenl, William

This article first shows Jung's evolving views of Nazi Germany from 1936 to the beginning of World War II. In a lecture at the Tavistock Clinic, London, in October 1936, he made his strongest and most negative statements to that date about Nazi Germany. While in Berlin in September 1937 for lectures to the Jung Gesellschaft, his observations of Hitler at a military parade led him to conclude that should the catastrophe of war come it would be far more and bloodier than he had previously supposed. After the Sudetenland Crisis in Fall 1938, Jung in interviews made stronger comments on Hitler and Nazi Germany. The article shows how strongly anti-Nazi Jung's views were in relation to events during World War II such as Nazi Germany's invasion of Poland, the fall of France, the bombings of Britain, the U.S. entry into the War, and Allied troops advancing into Germany. Schoenl and Peck, 'An Answer to the Question: Was Jung, for a Time, a "Nazi Sympathizer" or Not?' (2012) demonstrated how his views of Nazi Germany changed from 1933 to March 1936. The present article shows how his views evolved from 1936 to the War's end in 1945. © 2014, The Society of Analytical Psychology.

Various light sources may be used for photodynamic therapy of actinic keratosis since photosensitizing agents are activated by different wavelengths. However, the relative impact of red and blue light irradiation on the efficacy and tolerability of therapy is controversial. The aim of this study is to compare the efficacy and tolerability of therapy with red versus blue light sources, as well as the patients' evaluation of cosmetic results, clinical response, painfulness and preferred light source for future photodynamic treatments. This is a prospective, single-center, randomized, controlled, open-label study with 28 patients undergoing elective photodynamic therapy. Red and blue light sources both showed very good results with a complete response rate of 84 % and 85 % respectively. Pain during photodynamic therapy was 6.1 vs. 5.4 (and 2.1 vs. 1.5 eight hours after therapy) on the visual analogue scale. Although these differences were statistically significant, the clinical relevance is low, since the number of therapy interruptions were equally distributed in both groups, and patients' subjective evaluation of the treatment showed no personal preference towards the light sources. Both light sources showed very good clinical results and satisfactory tolerability in this study. © 2018 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

The World Congress of Herpetology (WCH, http://www.worldcongressofherpetology.org/) is a relatively young organization as far as august herpetological societies go. It was formed in 1982, the year of the 25th meeting of the Society for the Study of Amphibians and Reptiles (founded in 1958), which itself is a relative youngster when compared to organizations such as the American Society for Ichthyology and Herpetology (founded in 1913) or Die Deutsche Gesellschaft für Herpetologie und Terrarienkunde e. V. (originally founded in 1918 under a different name). Despite its youth, the WCH has accomplished much during its relatively short existence. Arguably the greatest accomplishment of the WCH was to provide the venue at the first meeting of the Congress, held in 1989 at Canterbury, UK, where numerous amphibian biologists shared tales of enigmatic declines and disappearances of amphibian study species. Undoubtedly these exchanges sparked the formation of the Declining Amphibian Populations Task Force, providing impetus for the establishment of IUCN's Global Amphibian Assessment. This assessment, along with other research, in turn confirmed that amphibians are declining at a global scale and are more threatened than any other vertebrate class comprehensively assessed to date (Houlahan et al., 2000; Stuart et al., 2004).

High current discharge channels can neutralize both current and space charge of very intense ion beams. Therefore, they are considered an interesting solution for final focus and beam transport in a heavy ion beam fusion reactor. At the Gesellschaft für Schwerionenforschung accelerator facility, 50 cm long, free-standing discharge channels were created in a 60 cm diameter metallic chamber. Discharges with currents of 45 kA in 2 to 25 mbar ammonia (NH3) gas are initiated by a CO2 laser pulse along the channel axis before the capacitor bank is triggered. Resonant absorption of the laser, tuned to the v2 vibration of the ammonia molecule, causes strong gas heating. Subsequent expansion and rarefaction of the gas prepare the conditions for a stable discharge to fulfill the requirements for ion beam transport. The influence of an electric prepulse on the high current discharge was investigated. This article describes the laser-gas interaction and the discharge initiation mechanism. We found that channels are magnetohydrodynamic stable up to currents of 45 kA, measured by fast shutter and streak imaging techniques. The rarefaction of the laser heated gas is studied by means of a one-dimensional Lagrangian fluid code (CYCLOPS) and is identified as the dominant initiation mechanism of the discharge.
Lymphomatoid papulosis - making sense of the alphabet soup: a proposal to simplify terminology.

Kempf, Werner; Mitteldorf, Christina; Karai, Laszlo J; Robson, Alistair

2017-04-01

Clinically, lymphomatoid papulosis (LYP) is characterized by recurrent papulonodular lesions. Unlike this stereotypical clinical presentation, the histological spectrum of LYP is very wide, comprising distinct growth patterns, variably sized neoplastic cells, and different immunophenotypes. The revised 2016 WHO classification includes the histological LYP types A to E as well as another type characterized by a specific chromosomal alteration. In addition, new LYP types are going to be proposed, based not only on histological but also on clinical and genetic features. The ensuing expansion of the alphabetical list of histological types will add to the complexity of the terminology of LYP, thereby potentially increasing the risk of complicating rather than facilitating the diagnostic approach to the disease. Moreover, there may be overlap between individual disease types. This development raises the question as to how to simplify the terminology of LYP while still respecting its histological complexity. Herein, we advocate a practical approach to the terminology of LYP based on descriptive terms rather than the designation of LYP types by alphabetical characters. Our proposal aims to contribute to a pragmatic and user-friendly approach, thus not only facilitating the diagnostic process but also the communication between clinicians and pathologists. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

EndoCert is an initiative of the Deutschen Gesellschaft für Orthopädie und Orthopädische Chirurgie (DGOOC, German Society for Orthopedics and Orthopedic Surgery) which has been available since October 2012 and is the first system worldwide for certification of specialized arthroplasty centers. Before implementation of this certification concept two sequential pilot phases were carried out with representative treatment institutions. The results from these pilot clinics are presented with respect to quality improvement effects. Early effects on the quality of treatment have been achieved by rectification of nonconformities determined in the audit with respect to structural and process quality. A total of 172 nonconformities found in the 23 participating pilot clinics could be rectified. Long-term effects on the quality of results will in future be analyzed in cooperation with the German endoprosthesis register (EPRD) and by accompanying evaluations. A close feedback of the collated experiences and results to the certification committee, which is responsible for the procedure together with the DGOOC, allows continuous further development of the system EndoCert represents a substantial step towards a nationwide safety and improvement of the quality in arthroplasty treatment within the preoperative, perioperative and postoperative framework and can in future represent a decisive tool together with the EPRD in quality management.

In the context of DRG-based hospital funding, the analysis of services provided in dermatologic inpatient care is highly relevant. We analyzed and compared clinical service structures and varieties in dermatologic hospitals through a benchmarking technique. For this multicenter cross-sectional study, routine data from 46 German dermatologic clinics and departments were collected, processed, and analyzed. In total, 95 257 data sets from 2011 were available. The data were grouped according to the G-DRG-system 2013 version. The average length of stay for all cases was 6.3 days (DRG "inliers": 5.7 days), and average patient age was 52 years. In total, 55 % of all cases were grouped to medical, 45 % to surgical DRGs. 71 % of all hospitals provide services within or close to this average value (± 10 %). No association was found between the number of hospital beds and the variety of clinical services provided in our sample. We found huge varieties in several parameters assessing the coding quality. The results reflect the heterogeneous reality in German inpatient dermatology. The varieties in dermatologic service range still depend on patient-related factors as well as infrastructural conditions and the resources available at each site. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

Oxidative stress is related to the pathogenesis and progress of several human diseases. NADPH oxidase (NOX), and mainly the NOX2 isoform, produces superoxide anions (O 2 • - ). To date, it is known that NOX2 can be inhibited by preventing the assembly of its subunits, p47phox and p22phox. In this work, we analyzed the binding to NOX2 of the apocynin dimer, diapocynin (C1), a known NOX2 inhibitor, and of 18 designed compounds (C2-C19) which have chemical relationships to C1, by in silico methods employing a p47phox structure from the Protein Data Bank (PDB code: 1WLP). C1 and six of the designed compounds were recognized in the region where p22phox binds to p47phox and makes π-π interactions principally with W193, W263, and Y279, which form an aromatic-rich region. C8 was chosen as the best compound according to the in silico studies and was synthesized and evaluated in vitro. C8 was able to prevent the production of reactive oxygen species (ROS) similar to C1. In conclusion, targeting the aromatic region of p47phox through π-interactions is important for inhibiting NOX activity. © 2017 Deutsche Pharmazeutische Gesellschaft.

Three series of tests were carried out on the model with a velocity head (or dynamic pressure) of 5 kg/sq m (1.02 lb/sq ft), during which one of the movable surfaces was deflected at various angles, while both the others were retained in their central positions. Of special interest among the results of the tests is the different run of the elevating moments. The curves for the A.E.G. model, rising to the right, denote stability with the elevator locked, while the slight inclination to the left with the D.F.W model denotes a slight instability. For the maximum C(sub L) values, the stability of A.E.G. model continues to increase and the instability of the D.F.W. model is converted into stability. The rolling moments shown when the angular deflection of the ailerons is 0 degrees are due, in both series of tests, to the unequal distribution of the air velocity over the cross section of the wind tunnel, rather than to a lack of symmetry in the model.

The ASTEC V1 system code is being jointly developed by the French Institut de Radioprotection et Sûreté Nucléaire (IRSN) and the German Gesellschaft für Anlagen und ReaktorSicherheit (GRS) to address severe accident sequences in a nuclear power plant. Thermal-hydraulics in primary and secondary system is addressed by the CESAR module. The aim of this paper is to present the validation of the CESAR module, from the ASTEC V1.2 version, on the basis of well instrumented and qualified integral experiments carried out in the BETHSY facility (CEA, France), which simulates a French 900 MWe PWR reactor. Three tests have been thoroughly investigated with CESAR: the loss of coolant 9.1b test (OECD ISP N° 27), the loss of feedwater 5.2e test, and the multiple steam generator tube rupture 4.3b test. In the present paper, the results of the code for the three analyzed tests are presented in comparison with the experimental data. The thermal-hydraulic behavior of the BETHSY facility during the transient phase is well reproduced by CESAR: the occurrence of major events and the time evolution of main thermal-hydraulic parameters of both primary and secondary circuits are well predicted.

The 4th European Congress of Virology, hosted by the Italian Society for Virology, attracted approximately 1300 scientists from 46 countries worldwide. It also represented the first conference of the European Society for Virology, which was established in Campidoglio, Rome, Italy in 2009. The main goal of the meeting was to share research activities and results achieved in European virology units/institutes and to strengthen collaboration with colleagues from both western and developing countries. The worldwide representation of participants is a testament to the strength and attraction of European virology. The 5-day conference brought together the best of current virology; topics covered all three living domains (bacteria, archaea and eucarya), with special sessions on plant and veterinary virology as well as human virology, including two oral presentations on mimiviruses. The conference included five plenary sessions, 31 workshops, one hepatitis C virus roundtable, ten special workshops and three poster sessions, as well as 45 keynote lectures, 191 oral presentations and 845 abstracts. Furthermore, the Gesellschaft fur Virologie Loeffler-Frosch medal award was given to Peter Vogt for his long-standing career and achievements; the Gardner Lecture of the European Society for Clinical Virology was presented by Yoshihiro Kawaoka, and the Pioneer in Virology Lecture of the Italian Society for Virology was presented by Ulrich Koszinowski.
Biosimilars in psoriasis: what can we expect?

PubMed

Radtke, Marc Alexander; Augustin, Matthias

2014-04-01

Biosimilars are biotechnologically processed drugs whose amino acid sequence is identical to the original biopharmaceutical. They are of considerable clinical, economical, and health care interest. As patents for biologicals used to treat psoriasis expire, biosimilars will become more and more important within the field of dermatology. The patents for the two top-selling drugs (adalimumab and etanercept) will terminate in the next few years. Applications for biosimilars will presumably be submitted to the EMA and the FDA for all patent-free biologicals. Both regulatory bodies have issued guidelines on the assessment of bioequivalence, as well as the benefits and risks of biosimilars. While the preclinical requirements of the FDA and EMA are largely comparable, the formal requirements for clinical bioequivalence, including clinical efficacy and safety, differ markedly. Therefore, from a medical and health care perspective before biosimilars enter the market, specific evidence-based regulatory conditions need to be created and fulfilled. Only then biosimilars can be a less expensive option for a large number of patients, providing them with substances of the same value. Adequate, unequivocal proof of their bioequivalence, quality, and related patient safety should have priority over any ostensible economic benefits. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

An important basis for adequate psycho-oncological and psychosocial care of cancer patients is the regular assessment of their psychosocial distress and thus their need for care. For this purpose, there are numerous questionnaires available. The objective of the present study was to assess whether distressed patients require professional support and which screening instrument outpatients with skin cancer prefer. In a cross-sectional survey, we asked outpatients with skin cancer to fill out three questionnaires assessing psychosocial stress, and to indicate which one they considered most adequate. Patients were offered the following three instruments: Hornheide Questionnaire (27 items), Hornheide Screening Instrument (7 items), and the Distress Thermometer. In addition, we inquired about the patients' desire for support. (1) Comparing subjective distress and patients' declared desire for support revealed a marked divergence. While one-third of the 137 patients were identified as being in need of care, only 11.5% of the sample requested such support. (2) 63.7% of patients chose the long version of the Hornheide Questionnaire. In addition to their psychosocial burden, patients' desire for support should be assessed. Moreover, apart from screening tools, other ways to provide access to psychosocial care should be considered. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Pemphigus is a group of autoimmune diseases characterized by intraepidermal acantholytic blisters. Isomorphic responses, or Koebner phenomenon (KP), defined as the appearance of typical lesions of a disease following trauma are rarely reported in pemphigus. Our aim was to present patients who developed new pemphigus lesions as a result of skin trauma. The medical files of pemphigus patients from the Autoimmune Bullous Diseases Research Center, who had a history of trauma before the onset or flare of their disease, between 1999 and 2013 were reviewed. Thirty-six pemphigus vulgaris (PV) patients had a history of trauma. Thirteen patients developed new-onset PV and the other 23 had previously been diagnosed with PV. Pemphigus lesions developed most often following major surgeries including abdominal, orthopedic, and chest surgeries as well as dental procedures, blunt physical trauma, and skin surgeries. Moreover, post-cataract laser surgery, burns, radiation therapy, and physiotherapy were also shown to induce pemphigus. Mean time between trauma and lesions was 4.7 weeks for recurrent PV and 15.0 weeks for new-onset PV. Unnecessary surgery and blunt trauma should be avoided in pemphigus patients. Furthermore, posttraumatic pemphigus should be suspected in poorly healing surgical wounds and confirmatory biopsies are mandatory. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

The sulfone dapsone has an established role in systemic therapy. Its pharmacological and toxicological properties are well known. Topically, dapsone is used in a gel formulation for the treatment of acne vulgaris. In addition, there have been individual case reports on the efficacy of topical dapsone preparations in the treatment of various neutrophilic dermatoses. To date, no finished medicinal product for topical use has been available in Germany. Against this background, we set out to develop extemporaneous preparations containing dapsone (5 %) that meet the quality requirements of the European Pharmacopoeia as well as the manufacturing requirements of the German Ordinance on the Operation of Pharmacies (ApBetrO). These formulations included the incorporation of dapsone in a hydrophobic cream base ("hydrophobe Basiscreme DAC") as well as in methylprednisolone aceponate 0.1 % ointment (alternatively, in the latter's cream base without active ingredient). Tests aimed at investigating the physical, chemical, and microbiological stability of these formulations showed them to meet the aforementioned quality requirements. The extemporaneous formulations presented herein broaden the therapeutic options for topical treatment, in particular for patients with chronic inflammatory dermatoses associated with a neutrophilic pathogenesis. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

In order to offer a more cost effective, safer and efficient Intermediate Level Waste (ILW) management service, EnergySolutions EU Ltd. and Gesellschaft fur Nuklear-Service mbH (GNS) have been engaged in the development of integrated radioactive waste retrieval, packaging and conditioning solutions in the UK. Recognising the challenges surrounding regulatory endorsement and on-site implementation in particular, this has resulted in an alternative approach to meeting customer, safety regulator and disposability requirements. By working closely with waste producers and the organisation(s) responsible for endorsing radioactive waste management operations in the UK, our proposed solutions are now being implemented. By combining GNS' off-the-shelf,more » proven Ductile Cast Iron Containers (DCICs) and water removal technologies, with EnergySolutions EU Ltd.'s experience and expertise in waste retrieval, safety case development and disposability submissions, a fully integrated service offering has been developed. This has involved significant effort to overcome technical challenges such as onsite equipment deployment, active commissioning, conditioning success criteria and disposability acceptance. Our experience in developing such integrated solutions has highlighted the importance of working in collaboration with all parties to achieve a successful and viable outcome. Ultimately, the goal is to ensure reliable, safe and effective delivery of waste management solutions. (authors)« less
Does choice of estimators influence conclusions from true metabolizable energy feeding trials?

Sherfy, M.H.; Kirkpatrick, R.L.; Webb, K.E.

2005-01-01

True metabolizable energy (TME) is a measure of avian dietary quality that accounts for metabolic fecal and endogenous urinary energy losses (EL) of non-dietary origin. The TME is calculated using a bird fed the test diet and an estimate of EL derived from another bird (Paired Bird Correction), the same bird (Self Correction), or several other birds (Group Mean Correction). We evaluated precision of these estimators by using each to calculate TME of three seed diets in blue-winged teal (Anas discors). The TME varied by <2% among estimators for all three diets, and Self Correction produced the least variable TMEs for each. The TME did not differ between estimators in nine paired comparisons within diets, but variation between estimators within individual birds was sufficient to be of practical consequence. Although differences in precision among methods were slight, Self Correction required the lowest sample size to achieve a given precision. Feeding trial methods that minimize variation among individuals have several desirable properties, including higher precision of TME estimates and more rigorous experimental control. Consequently, we believe that Self Correction is most likely to accurately represent nutritional value of food items and should be considered the standard method for TME feeding trials. ?? Dt.

International agreement concerning validation guidelines is important to obtain quality forensic bioanalytical research and routine applications as it all starts with the reporting of reliable analytical data. Standards for fundamental validation parameters are provided in guidelines as those from the US Food and Drug Administration (FDA), the European Medicines Agency (EMA), the German speaking Gesellschaft fur Toxikologie und Forensische Chemie (GTFCH) and the Scientific Working Group of Forensic Toxicology (SWGTOX). These validation parameters include selectivity, matrix effects, method limits, calibration, accuracy and stability, as well as other parameters such as carryover, dilution integrity and incurred sample reanalysis. It is, however, not easy for laboratories to implement these guidelines into practice as these international guidelines remain nonbinding protocols, that depend on the applied analytical technique, and that need to be updated according the analyst's method requirements and the application type. In this manuscript, a review of the current guidelines and literature concerning bioanalytical validation parameters in a forensic context is given and discussed. In addition, suggestions for the experimental set-up, the pros and cons of statistical approaches and adequate acceptance criteria for the validation of bioanalytical applications are given.

The Stratospheric Observatory for Infrared Astronomy (SOFIA) is a joint project between NASA and Deutsches Zentrum fuer Luft- und Raumfahrt (DLR), the German Space Agency. SOFIA is based in a Boeing 747 SP and flown in the stratosphere to observe infrared wavelengths unobservable from the ground. In 2007 Dryden Flight Research Center (DFRC) inherited and began work on improving the plane and its telescope. The improvements continue today with upgrading the plane and improving the telescope. The Observatory Verification and Validation (V&V) process is to ensure that the observatory is where the program says it is. The Telescope Status Display (TSD) will provide any information from the on board network to monitors that will display the requested information. In order to assess risks to the program, one must work through the various threats associate with that risk. Once all the risks are closed the program can work towards improving the observatory.

One important step toward public education about fusion energy is to first elevate the public's appreciation of science in general. Toward this end, the Wonders of Physics program was started at the University of Wisconsin-Madison in 1984 as a public lecture and demonstration series in an attempt to stem a growing tide of science illiteracy and to bolster the public's perception of the scientific enterprise. Since that time, it has grown into a public outreach endeavor which consists of a traveling demonstration show, educational pamphlets, videos, software, a website (http://sprott.physics.wisc.edu/wop.htm), and the annual public lecture demonstration series including tours highlighting the Madison Symmetric Torus and departmental facilities. The presentation has been made about 400 times to a total audience in excess of 50,000. Sample educational materials and Lecture Kits will be available at the poster session.

Solar adaptive optics (AO) simulations are a valuable tool to guide the design and optimization process of current and future solar AO and multi-conjugate AO (MCAO) systems. Solar AO and MCAO systems rely on extended object cross-correlating Shack-Hartmann wavefront sensors to measure the wavefront. Accurate solar AO simulations require computationally intensive operations, which have until recently presented a prohibitive computational cost. We present an update on the status of a solar AO and MCAO simulation tool being developed at the National Solar Observatory. The simulation tool is a multi-threaded application written in the C++ language that takes advantage of current large multi-core CPU computer systems and fast ethernet connections to provide accurate full simulation of solar AO and MCAO systems. It interfaces with KAOS, a state of the art solar AO control software developed by the Kiepenheuer-Institut fuer Sonnenphysik, that provides reliable AO control. We report on the latest results produced by the solar AO simulation tool.

Dermatologists are increasingly confronted with patients affected by body dysmorphic disorder (BDD). BDD is characterized by excessive preoccupation with one or more perceived defect(s) or flaw(s) in physical appearance which are not observable or appear slight to others. So far, there have been only few studies examining the prevalence of BDD in dermatological outpatients. In addition, the need for psychotherapeutic support in dermatological outpatients with body dysmorphic concerns has not yet been systematically examined. The objective of the present study was therefore to investigate the frequency of body dysmorphic concerns as well as social adaptation and the need for psychotherapeutic support in the aforementioned patient group. A total of 252 dermatological outpatients seen at a German university hospital were consecutively enrolled, and examined using the Dysmorphic Concerns Questionnaire, the Social Adaptation Self-Evaluation Scale, and the German version of the University of Rhode Island Change Assessment Scale. 7.9 % of all outpatients (unselected sample) showed positive test results, suggesting clinically relevant body dysmorphic concerns. Patients with clinically relevant body dysmorphic concerns exhibited poor social adaptation. Contrary to expectations, these patients revealed a high motivation for change, indicating the necessity for psychotherapeutic support. Our findings confirm previous prevalence rates of BDD in dermatological outpatients, and highlight the need for providing psychotherapeutic support to dermatological patients. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Scarring is the consequence of surgery, trauma or different skin diseases. Apart from fresh, immature scars,that transform into mature scars over the course of would healing and that do not require further treatment,linear hypertrophic scars, widespread hypertrophic scars, keloids and atrophic scars exist. Symptoms like pruritusand pain, stigmatization as well as functional and aesthetic impairments that are very disturbing for the affected patients can bethe basis for the desire for treatment. Today, a multitude of options for the treatment and prevention of scars exists. Topical agents based on silicone or onion extract, intralesional injections of cristalline glucocorticoids (oftentimes in combinationwith cryotherapy) or 5-Fluorouracil as well as ablative and nonablative laser treatment are used. Current guidelines summarize the multitude of available treatment options and the currently available datafor the treating physicians, allowing them to make clear therapy recommendations for every single scar type. Relieving patients of their discomfort and doing their aesthetic demands justice is thus possible. Apart from scar prevention becoming more and more important, the increased use of modernlaser treatment options constitutes a key point in clinical scar treatment. At the same time the attention is turned to evaluating current therapeutic options with the help of contemporary study designs so as to graduallyimprove the level of evidence in scar treatment. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Die vorliegende überarbeitete Leitlinie zum Lipödem wurde unter der Federführung der Deutschen Gesellschaft für Phlebologie (DGP) erstellt und finanziert. Die Inhalte beruhen auf einer systematischen Literaturrecherche und dem Konsens von acht medizinischen Fachgesellschaften und Berufsverbänden. Die Leitlinie beinhaltet Empfehlungen zu Diagnostik und Therapie des Lipödems. Die Diagnose ist dabei auf der Basis von Anamnese und klinischem Befund zu stellen. Charakteristisch ist eine umschriebene, symmetrisch lokalisierte Vermehrung des Unterhautfettgewebes an den Extremitäten mit deutlicher Disproportion zum Stamm. Zusätzlich finden sich Ödeme, Hämatomneigung und eine gesteigerte Schmerzhaftigkeit der betroffenen Körperabschnitte. Weitere apparative Untersuchungen sind bisher besonderen Fragestellungen vorbehalten. Die Erkrankung ist chronisch progredient mit individuell unterschiedlichem und nicht vorhersehbarem Verlauf. Die Therapie besteht aus vier Säulen, die individuell kombiniert und an das aktuelle Beschwerdebild angepasst werden sollten: komplexe physikalische Entstauungstherapie (manuelle Lymphdrainage, Kompressionstherapie, Bewegungstherapie, Hautpflege), Liposuktion und plastisch-chirurgische Interventionen, Ernährung und körperliche Aktivität sowie ggf. additive Psychotherapie. Operative Maßnahmen sind insbesondere dann angezeigt, wenn trotz konsequent durchgeführter konservativer Therapie noch Beschwerden bestehen bzw. eine Progredienz des Befundes und/oder der Beschwerden auftritt. Eine begleitend zum Lipödem bestehende morbide Adipositas sollte vor einer Liposuktion therapeutisch angegangen werden. © 2017 The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.
A Review of Update Clinical Results of Carbon Ion Radiotherapy

PubMed Central

Tsujii, Hirohiko; Kamada, Tadashi

2012-01-01

Among various types of ion species, carbon ions are considered to have the most balanced, optimal properties in terms of possessing physically and biologically effective dose localization in the body. This is due to the fact that when compared with photon beams, carbon ion beams offer improved dose distribution, leading to the concentration of the sufficient dose within a target volume while minimizing the dose in the surrounding normal tissues. In addition, carbon ions, being heavier than protons, provide a higher biological effectiveness, which increases with depth, reaching the maximum at the end of the beam's range. This is practically an ideal property from the standpoint of cancer radiotherapy. Clinical studies have been carried out in the world to confirm the efficacy of carbon ions against a variety of tumors as well as to develop effective techniques for delivering an efficient dose to the tumor. Through clinical experiences of carbon ion radiotherapy at the National Institute of Radiological Sciences and Gesellschaft für Schwerionenforschung, a significant reduction in the overall treatment time with acceptable toxicities has been obtained in almost all types of tumors. This means that carbon ion radiotherapy has meanwhile achieved for itself a solid place in general practice. This review describes clinical results of carbon ion radiotherapy together with physical, biological and technological aspects of carbon ions. PMID:22798685

Obwohl subklinische Enthesiopathie ein gut etabliertes diagnostisches Merkmal der Psoriasisarthritis (PsA) ist, wird sie häufig übersehen, da viele Patienten asymptomatisch sind. Gäbe es klinische Hinweise auf das Vorliegen einer Enthesiopathie, würde dies den Klinikern die Möglichkeit eröffnen, eine PsA frühzeitig zu diagnostizieren. Es wurde eine monozentrische prospektive Studie mit insgesamt 90 Psoriasis-Patienten durchgeführt, um mittels Ultraschall das Vorliegen von Enthesenanomalien zu untersuchen und eine Korrelation mit dem Befall der Nägel festzustellen. Enthesenanomalien wurden bei 23 Patienten (25,5 %) gefunden, von denen 19 (82,6 %) Nagelbefall aufwiesen. Bei 4 Patienten waren die Nägel nicht betroffen. Enthesiopathie lag bei 31,1 % (19/61) der Patienten mit Onychopathie vor, von den Patienten ohne Nagelbefall litten nur 13,8 % (4/29) an Enthesiopathie (p = 0,07). Zwischen dem Target-NAPSI-Score und dem Vorliegen einer Enthesiopathie bestand eine signifikante Korrelation. Eine signifikante Korrelation bestand darüber hinaus auch zwischen dem Vorliegen einer Enthesiopathie und der Anzahl der betroffenen Nägel (p = 0,035). Klinische Belege für eine Onychopathie können der Schlüssel für die frühe Diagnose einer Enthesiopathie bei Psoriasis-Patienten sein. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Die Behandlung von Psoriasis-Patienten mit einer Kombination aus Fumarsäureestern (FSE, Fumaderm ® ) und Phototherapie (UV) ist verbreitet, wurde aber im Rahmen von Studien wenig untersucht. Bisher liegen lediglich Daten aus einer kleinen Pilotstudie vor. Intention dieser Studie war, eine FSE/UV-Kombinationsbehandlung an einem größeren Patientenkollektiv mit mittelschwerer bis schwerer Psoriasis zu untersuchen. In dieser prospektiven, multizentrischen, nichtinterventionellen Studie wurden Daten von Patienten mit FSE/UV-Kombinationstherapie hinsichtlich der Wirksamkeit (PGA' PASI, DLQI, EQ-5D), Sicherheit und Dosierung über einen Zeitraum von zwölf Monaten erfasst und mit Daten einer retrospektiven Studie mit FSE-Monotherapie verglichen. Es wurden Daten von 363 Patienten ausgewertet. Unter der Kombinationstherapie verbesserten sich alle Wirksamkeitsparameter deutlich. Im Vergleich zur Monotherapie mit FSE konnte durch die Kombination mit UV ein schnellerer Wirkeintritt erzielt werden, wobei nach zwölf Monaten kein Unterschied in der Wirksamkeit bestand. Die Dauer und Art der Phototherapie zeigte keinen Einfluss auf die Wirksamkeitsparameter. Allgemein wurde die Kombinationstherapie gut vertragen. Unerwünschte Ereignisse wurden bei 7 % der Patienten berichtet. Die FSE/UV Kombinationstherapie zeigt eine gute Wirksamkeit und Verträglichkeit und kann zu einem schnelleren Wirkeintritt führen. Eine Kombinationstherapie erscheint vor allem in den ersten drei Monaten der FSE Behandlung sinnvoll. © 2017 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Primary immunodeficiencies are potentially life-threatening diseases. Over the last years, the clinical phenotype and the molecular basis of an increasing number of immunological defects have been characterized. However, in daily practice primary immunodeficiencies are still often diagnosed too late. Considering that an early diagnosis may reduce morbidity and mortality of affected patients, an interdisciplinary guideline for the diagnosis of primary immunodeficiencies was developed on behalf of the Arbeitsgemeinschaft Pädiatrische Immunologie (API) and the Deutsche Gesellschaft für Immunologie (DGfI). The guideline is based on expert opinion and on knowledge from other guidelines and recommendations from Germany and other countries, supplemented by data from studies that support the postulated key messages (level of evidence III). With the contribution of 20 representatives, belonging to 14 different medical societies and associations, a consensus-based guideline with a representative group of developers and a structured consensus process was created (S2k). Under the moderation of a representative of the Association of the Scientific Medical Societies in Germany (AWMF) the nominal group process took place in April 2011. The postulated key messages were discussed and voted on following a structured consensus procedure. In particular, modified warning signs for primary immunodeficiencies were formulated and immunological emergency situations were defined. © Georg Thieme Verlag KG Stuttgart · New York.

The National Cancer Aid Monitoring of Tanning Bed Use (NCAM) project is a major German study that aims to observe the most significant risk factors for skin cancer: natural sunlight and artificial UV radiation. NCAM is a nationwide cross-sectional survey that will initially involve four rounds of data collection (so-called waves) between 2015 and 2018. Every year, a representative nationwide sample consisting of 3,000 individuals aged between 14 and 45 years will be surveyed. The cross-sectional survey will be complemented by a panel of n = 450 current tanning bed users. The initial wave in 2015 shows an overall prevalence of tanning bed use of 29.5 %. Eleven percent of all participants had used a tanning bed within the past twelve months. Determinants of current tanning bed use included younger age, female gender, and full-time/part-time employment. The main motivations for tanning bed use reported were relaxation and increased attractiveness. NCAM is the first study worldwide to monitor skin cancer risk factors at one-year intervals using a large, nationally representative sample. Initial results indicate that, despite WHO warnings, millions of Germans use tanning beds, and that many of these users are adolescents despite legal restrictions aimed at preventing minors from using tanning beds. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Xeroderma pigmentosum (XP) is an autosomal recessive disease, caused by a gene defect in the nucleotide-excision-repair (NER) pathway or in translesional DNA synthesis. At the age of eight, patients already develop their first skin cancers due to this DNA repair defect. In contrast, in the Caucasian population the first tumor formation in UV exposed skin regions occurs at a mean age of 60. The clinical picture among patients suffering from XP is highly diverse and includes signs of accelerated skin aging, and UV-induced skin cancers, as well as ophthalmologic and neurological symptoms. Patients should therefore receive interdisciplinary care. This includes dermatologists, ophthalmologists, ENT specialists, neurologists, and human geneticists. Patients with XP are clinically diagnosed, but this may be supported by molecular-genetic and functional analyses. These analyses allow pinpointing the exact disease-causing gene defect (complementation group assignment, detection of the type and location of the mutation within the gene). The resulting information is already relevant to predict the course of disease and symptoms and probably will be utilized for individualized therapeutic approaches in the future. Recently, enhanced repair of UV photolesions in xeroderma pigmentosum group C cells induced by translational readthrough of premature termination codons by certain antibiotics could be demonstrated. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

Several Advanced Energy Systems (AES) accelerator projects that span applications in Discovery Science and Security are described. The design and performance of the IR and THz free electron laser (FEL) at the Fritz-Haber-Institut der Max-Planck-Gesellschaft in Berlin that is now an operating user facility for physical chemistry research in molecular and cluster spectroscopy as well as surface science, is highlighted. The device was designed to meet challenging specifications, including a final energy adjustable in the range of 15-50 MeV, low longitudinal emittance (<50 keV-psec) and transverse emittance (<20 π mm-mrad), at more than 200 pC bunch charge with a micropulse repetition rate of 1 GHz and a macropulse length of up to 15 μs. Secondly, we will describe an ongoing effort to develop an ultrafast electron diffraction (UED) source that is scheduled for completion in 2015 with prototype testing taking place at the Brookhaven National Laboratory (BNL) Accelerator Test Facility (ATF). This tabletop X-band system will find application in time-resolved chemical imaging and as a resource for drug-cell interaction analysis. A third active area at AES is accelerators for security applications where we will cover some top-level aspects of THz and X-ray systems that are under development and in testing for stand-off and portal detection.
The mystery of the thymus gland.

The thymus is the last organ in the human body to have its mechanisms fully understood, having had its function fully delineated more than 50 years ago (Miller , Tissue Antigens 63:509-517). Prior to this, the thymus gland has had an interesting history with theories having included a role in fetal growth and development before becoming more sinisterly, a cause of sudden infant death in the late 19th century known as status lymphaticus (Paltauf , Wien Klin Wochenschr 2:877-881). Until Miller (, Lancet 278:748-749) eventually proved its primarily immunological role, the history of this mysterious gland has closely mirrored the history of medicine itself, troubling the minds of pathologists such as Virchow (, Ueber die Chlorose und die damit zusammenhängenden Anomalien im Gefässapparate, insbesondere über "Endocarditis puerperalis," vorgetragen in der Sitzung der Berliner Geburtshülflichen Gesellschaft vom 12) and Grawitz (, Deut Med Wochenschr 22:429-431), surgeons such as Astley Cooper (, The Anatomy of the Thymus Gland) and Keynes (1953, Ann R Coll Surg 12:88), and eminent medical epidemiologists such as Greenwood and Woods [, J Hyg (Lond) 26:305-326].

The Choosing wisely initiative of the German Society of Internal Medicine ("Deutschen Gesellschaft für Innere Medizin," DGIM) and its 12 core focus area specialist societies were brought into being in 2014. The German initiative differs from the American campaign in that it not only considers overuse of diagnostic and therapeutic healthcare services, but also addresses procedures which are frequently not performed although they would bring benefits for patients. Furthermore, the recommendations were approved by an interdisciplinary consensus commission under consideration of all key internal medicine aspects. Since 2014, the initiative has received widespread attention. The 115 recommendations approved by the consensus commission have meanwhile been published in 20 articles. An array of measures were subsequently adopted to further promote the Choosing wisely recommendations ("Klug-entscheiden-Empfehlungen," KEE). These include the systematic incorporation of KEE symposia into DGIM annual congresses and the congresses of the core focus area specialist societies, as well as consideration of the KEE during establishment of future guidelines. Particular attention was paid to the importance of initiating and promoting a research project aimed at familiarizing medical students with the principles and content of the Choosing wisely initiative. The decision for or against specific diagnostic and therapeutic procedures represents an essential medical competence, which should therefore be trained prior to qualification.

Drugs used in breast cancer treatments target the suppression of estrogen biosynthesis. During this suppression, the main goal is to inhibit the aromatase enzyme that is responsible for the cyclization and structuring of estrogens either with steroid or non-steroidal-type inhibitors. Non-steroidal derivatives generally have a planar aromatic structure attached to the triazole ring system in their structures, which inhibits hydroxylation reactions during aromatization by coordinating the heme group. Bioisosteric replacement of the triazole ring system and development of aromatic/cyclic structures of the side chain can increase the selectivity for aromatase enzyme inhibition. In this study, pyridine-substituted thiazolylphenol derivatives, which are non-steroidal triazole bioisosteres, were synthesized using the Hantzsch method, and physical analysis and structural determination studies were performed. The IC 50 values of the compounds were determined by a fluorescence-based aromatase inhibition assay. Then, their antiproliferative activities on the MCF7 and HEK 293 cell lines were evaluated with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Furthermore, the crystal structure of human placental aromatase was subjected to a series of docking experiments to identify the possible interactions between the most active structure and the active site. Lastly, an in silico technique was performed to analyze and predict the drug-likeness, molecular and ADME properties of the synthesized molecules. © 2018 Deutsche Pharmazeutische Gesellschaft.

Die Behandlungsstrategie beim metastasierten Melanom hat sich mit der Identifizierung therapeutisch angreifbarer molekularer Zielstrukturen innerhalb zellulärer Signalwege radikal geändert. Durch die Zulassung von Substanzen, die gezielt an den zentralen Schaltmolekülen, den Phosphokinasen, angreifen, können diese Signalwege selektiv abgeschaltet werden. Dies ist insbesondere bei denjenigen Tumoren von Interesse, deren Signalwege durch aktivierende Mutationen der für die Schaltmoleküle kodierenden Gene konstitutiv aktiviert sind. Aktuell ist diese therapeutische Strategie insbesondere für Patienten bedeutsam, deren Melanome eine Mutation im BRAF-Gen aufweisen. Diese Patienten können durch eine Kombinationstherapie aus Inhibitoren der Phosphokinasen BRAF und MEK langfristig mit sehr guter Krankheitskontrolle behandelt werden. Unter dieser Kombinationstherapie wird aktuell ein progressionsfreies Überleben von über zehn Monaten und ein Gesamtüberleben von mehr als zwei Jahren bei guter Lebensqualität erzielt. Da unter längerfristiger Therapie mit Kinaseinhibitoren jedoch bei einem Großteil der Patienten eine Resistenzbildung auftritt, sind aktuelle klinische Therapiestudien auf die Suche nach geeigneten Kombinationspartnern unter Blockierung anderer Signalwege oder unter Aktivierung der T-Zell-vermittelten Immunantwort ausgerichtet. Der vorliegende Übersichtsartikel stellt sowohl die aktuell verfügbaren als auch die in der klinischen Testung befindlichen zukünftigen Optionen der zielgerichteten Therapie des Melanoms dar. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Der Zusammenhang zwischen Lungenkrebs und Ekzemen bleibt umstritten. Frühere Studien haben zu widersprüchlichen Ergebnissen geführt. Diese retrospektive populationsbasierte Kohortenstudie zielt darauf ab, das Risiko von Lungenkrebs im Zusammenhang mit Ekzemen abzuklären. In der Forschungsdatenbank der taiwanesischen nationalen Krankenversicherung identifizierten wir 43719 Patienten, bei denen in den Jahren 2000 bis 2010 ein Ekzem neu diagnostiziert wurde. Die Vergleichskohorte bildeten 87438 zufällig ausgewählte, altersangepasste Patienten ohne Ekzem. Die Fälle aus diesen beiden Kohorten wurden bis 2011 verfolgt. Zur Kalkulation des Lungenkrebsrisikos bei Ekzempatienten wurde die Cox-Regression verwendet. Die Datenbank enthielt keine Informationen über Raucherstatus, Alkoholkonsum, sozioökonomischen Status oder Familienanamnese. Nach der Bereinigung um Alter und Komorbidität hatte die Population mit Ekzemen ein um 2,80 erhöhtes Risiko für die Entwicklung von Lungenkrebs gegenüber der Vergleichskohorte (bereinigte Hazard-Ratio 2,80, 95 % Konfidenzinterval 2,59-3,03). Ekzempatienten mit Begleiterkrankungen, darunter Asthma, chronisch obstruktive Lungenerkrankungen, alkoholbedingten Leberschäden oder Diabetes, hatten ein höheres Lungenkrebsrisiko als Patienten ohne Ekzeme oder Komorbidität. Ekzeme gehen mit einem höheren Risiko für die Entwicklung von Lungenkrebs einher. Weitere Studien mit umfassenderen Informationen über weitere potentielle Einflussfaktoren sind sinnvoll. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Die Dermatochirurgie nimmt hinsichtlich vieler Punkte eine Sonderstellung unter den operativen Fächern ein. Hierzu gehört in erster Linie die Tatsache, dass bis auf wenige Ausnahmen fast alle Eingriffe traditionell in Lokal- bzw. Regionalanästhesie und oft auch in räumlich-infrastruktureller Trennung von den großen Zentral-Operationssälen stattfinden können. Die peri- und postoperative Überwachung obliegt dabei dem dermatochirurgischen Operationsteam. Das sui generis kleinere OP-Team hat somit eine ganze Reihe perioperativer Notwendigkeiten zu beachten, um die sich in den "großen" chirurgischen Fächern eine Vielzahl verschiedener beteiligter Fachgruppen gemeinsam kümmern. Hierzu gehören neben Hygieneaspekten, Kenntnissen in der Überwachung der Patienten sowie dem Aspekt der surgical site infections auch Fragen zur postoperativen Schmerztherapie sowie detailliertes pharmakologisches Wissen über die zur Anwendung kommenden Lokalanästhetika und das Handling der damit assoziierten toxischen und allergischen Reaktionen. Eine interdisziplinäre Zusammenarbeit und Verantwortung für den Patienten ist notwendig und erfordert die Erarbeitung und Umsetzung qualitätsorientierter und evidenzbasierter Handlungsanweisungen, die im dermatochirurgischen OP-Setting meist weit über das eigentliche Fach hinausgehen. Ziel dieses Weiterbildungsartikels soll die komprimierte Darstellung der genannten fachübergreifenden Standpunkte bezüglich der wichtigsten perioperativen Aspekte sein. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

The increase in minimum inhibitory concentrations (MICs) of cephalosporins for Neisseria gonorrhoeae has given rise to concerns regarding potentially untreatable gonococcal infections. The goal was to ascertain the prevalence of gonorrhea in a Viennese patient group and determine resistance patterns. Another objective was to evaluate resistance profiles and MIC values of gonococcal isolates in an Austria-wide surveillance project. From 1999 to 2014, 350,000 individuals were tested for gonococci at the Viennese Outpatient Clinic. In addition, from 2010 to 2014, the MICs of recommended antibiotics was determined in 3,584 gonococcal isolates, initially by agar dilution and breakpoint determination, and, from 2012 onwards, by Etest®. During the observation period, the prevalence of gonorrhea increased eightfold, with a significantly greater number of quinolone, penicillin, and tetracycline- resistant strains. In gonococcal strains isolated from across Austria, there was an increase in cefixime and ceftriaxone MICs toward breakpoints. Twenty-one isolates showed cefixime resistance, and while there was an increase in azithromycin resistance from 0.9 % (2013) to 3.2 % (2014), no resistance to ceftriaxone was observed. Currently, there is no imminent risk of untreatable gonorrhea in Austria. However, continuing the use of gonococcal cultures as a diagnostic tool for establishing resistance profiles is essential in order to monitor trends in the development of Neisseria (N.) gonorrhoeae resistance. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

To analyze symptomatic treatment in patients with multiple sclerosis (MS). Multiple sclerosis is a chronic inflammatory disease of the central nervous system, with accumulating disability symptoms like spasticity, voiding disorders, depression, and pain might occur. The nationwide German MS registry was initiated 2001 under guidance of the German MS society (Deutsche MS Gesellschaft). This study was performed as an interim analysis to lay foundation for future work on this topic. A subcohort of 5113 patients was assessed for this interim analysis. The mean age of the patients was 45.3 years; mean EDSS was 4.2. More than two-third of the enrolled patients were females (70.9%). Most frequent symptoms were fatigue (60%), followed by spasticity (52.5%) and voiding disorders (51.7%). The likelihood of treatment was highest for epileptic disorders (68.8%), spasticity (68.5%), pain (60.7%), and depression (58.9%). Multivariate regression analysis showed that retirement was the strongest factor predictive for antispastic treatment (β=.061, P=.005). Almost all patients in this analysis suffer from symptoms due to advanced MS. Treatment for the various symptoms differed tremendously. The likelihood of treatment correlated with the availability of effective therapeutic agents. Clinicians should put more awareness on MS symptoms. Symptomatic treatment may improve quality of life. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Assessment of the efficacy of azelaic acid 20 % cream (Skinoren ® ) on acne severity and disease-related QoL. Noninterventional study in adult female patients with mild to moderate acne. Efficacy variables included DLQI and acne severity on the face, chest, and back using the Investigator's Global Assessment (IGA) scale (grade 1 = nearly clear skin; 2 = mild acne; 3 = moderate acne). Visits were scheduled at baseline, at 4-8 weeks, and at twelve weeks. Of the 251 women enrolled, 59 % had grade 1 acne at baseline; 31 %, grade 2; and 10 %, grade 3; the most commonly affected area of the body was the face (IGA grades 2 or 3: 79 %). After twelve weeks, there was significant improvement of acne on the face (IGA grades 0 or 1: 82 %), chest, and back. Median DLQI decreased from nine at baseline to five after twelve weeks. Ninety percent of physicians and patients rated the tolerability of the treatment as very good or good. Treatment with azelaic acid 20 % cream significantly improves acne severity and disease-related QoL in adult women. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

The association between lung cancer and eczema remains controversial. Previous studies have yielded conflicting results. This retrospective population-based cohort study is aimed at clarifying the risk of lung cancer associated with eczema. By using the Taiwan National Health Insurance Research Database, we identified 43,719 patients who had been newly diagnosed with eczema in the years 2000 to 2010. The comparison cohort included 87,438 randomly selected, age-matched patients without eczema. The cases of these two cohorts were followed until 2011. The Cox proportional hazard regression model was used to calculate the risk of lung cancer in eczema patients. The database did not contain any information regarding smoking, alcohol consumption, socioeconomic status, or family history. After adjusting for age and comorbidity, the population with eczema had a 2.80-fold greater risk of developing lung cancer compared with the population in the comparison cohort (adjusted hazard ratio 2.80, 95 % confidence interval 2.59-3.03). Eczema patients with comorbid diseases including asthma, chronic obstructive -pulmonary disease, alcoholic liver damage, or diabetes were at a higher risk of lung cancer compared with the non-eczema patients without comorbidity. Eczema is associated with a greater risk for the development of lung cancer. Further studies with more comprehensive information on potential confounders are warranted. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.
Hand dermatitis--differential diagnoses, diagnostics, and treatment options.

PubMed

Mahler, Vera

2016-01-01

The pathogenesis of hand dermatitis is multifactorial, and includes factors such as genetic predisposition and exposure. A high incidence rate is associated with female gender, contact allergy, atopic dermatitis, and wet work. The most important risk factors for the persistence of hand dermatitis include its extent, contact allergic or atopic etiology, childhood dermatitis, and early onset (before the age of 20). The cost of illness of hand dermatitis corresponds to this seen in moderate to severe psoriasis. The diagnostic workup of hand dermatitis and its differential diagnoses requires a detailed assessment of occupational and recreational exposure. In case of possible work-related triggers, early notification of the accident insurer should be sought (via the dermatologist's report). Exposure to a contact allergen is a contributing factor in one-half of all cases of hand dermatitis. It is therefore imperative that all patients with hand dermatitis persisting for more than three months undergo patch testing. Successful and sustainable treatment of hand dermatitis starts with the proper identification and elimination of individual triggers, including the substitution of identified contact allergens and irritants, as well as optimizing preventive measures. Graded therapy taking the clinical severity into account is essential. Validated instruments may be used to monitor therapeutic efficacy. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

ALTEA-MICE will supplement the ALTEA project on astronauts and provide information on the functional visual impairment possibly induced by heavy ions during prolonged operations in microgravity. Goals of ALTEA-MICE are: (1) to investigate the effects of heavy ions on the visual system of normal and mutant mice with retinal defects; (2) to define reliable experimental conditions for space research; and (3) to develop animal models to study the physiological consequences of space travels on humans. Remotely controlled mouse setup, applied electrophysiological recording methods, remote particle monitoring, and experimental procedures were developed and tested. The project has proved feasible under laboratory-controlled conditions comparable in important aspects to those of astronauts' exposure to particle in space. Experiments are performed at the Brookhaven National Laboratories [BNL] (Upton, NY, USA) and the Gesellschaft fur Schwerionenforschung mbH [GSI]/Biophysik (Darmstadt, FRG) to identify possible electrophysiological changes and/or activation of protective mechanisms in response to pulsed radiation. Offline data analyses are in progress and observations are still anecdotal. Electrophysiological changes after pulsed radiation are within the limits of spontaneous variability under anesthesia, with only indirect evidence of possible retinal/cortical responses. Immunostaining showed changes (e.g. increased expression of FGF2 protein in the outer nuclear layer) suggesting a retinal stress reaction to high-energy particles of potential relevance in space. c2004 COSPAR.

Macrophages - sensors and effectors coordinating skin damage and repair.

Restoration of skin integrity and homeostasis following injury is a vital process. Wound healing disorders, including chronic skin ulcers and pathological scarring, are of major clinical impact. The current therapeutic approaches are often not sufficient. The development of novel efficient therapies requires a thorough understanding of the underlying molecular mechanisms. A cardinal feature of non-healing skin ulcers and excessive scarring is a prolonged inflammatory response at the wound site, which aborts the healing response. Modulation of the local immune response may be an effective therapeutic strategy to correct impaired healing conditions. Yet, the specific mechanisms of inflammation, particularly the role of the diverse leukocyte lineages attracted to the site of tissue damage, have not been resolved. Recent findings in diverse experimental model systems and clinical studies have refined the understanding of monocyte/macrophage biology and the role of cells of the monocytic lineage in tissue regeneration. Thus, monocytes/macrophages are emerging as novel and interesting therapeutic targets to interfere in wound healing pathologies. In this article we will review the role of monocytes/macrophages in skin repair in the light of the recent literature and findings from our own group. This article will provide a rationale for monocyte/macrophage-based therapies to facilitate the healing response. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

Als Lipomatosen bezeichnet man gutartige, meist ohne eindeutige Auslöser auftretende Vermehrungen des Fettgewebes, oft mit typischem Verteilungsmuster. Im Gegensatz zu umschriebenen Lipomen entwickeln sie sich meist diffus-symmetrisch und sind nicht von einer fibrösen Pseudokapsel umgeben. Am häufigsten ist die benigne symmetrische Lipomatose (BSL; Launois-Bensaude-Syndrom), von der aufgrund des Verteilungsmusters des hyperplastischen Fettgewebes vier Typen unterschieden werden. Ätiologie und Pathogenese der Erkrankung sind noch weitgehend unbekannt, wobei manche Formen eine hereditäre Basis zu haben oder mit vermehrtem Alkoholkonsum assoziiert zu sein scheinen. In einigen Fällen wurden mitochondriale Fehlfunktionen nachgewiesen. Lipomatosen können isoliert, aber auch mit Begleitsymptomen oder -erkrankungen (Komorbidität) vergesellschaftet auftreten. Wirksame medikamentöse Therapien sind nicht bekannt; chirurgische Verfahren können hingegen zur Besserung der Symptome führen. Die von der BSL abzugrenzende Lipomatosis dolorosa tritt bevorzugt bei Frauen mittleren Alters auf und ist durch Vermehrung des Fettgewebes sowie starke Schmerzen in den betroffenen Bereichen gekennzeichnet. Verschiedene Differenzialdiagnosen und Begleiterkrankungen sind abzuklären, insbesondere Depressionen. Evidenzbasierte Therapieempfehlungen existieren nicht. Repetitive Lidocain-Infusionen können temporäre Besserungen bewirken; nach chirurgischen Interventionen treten häufig Rezidive auf, allerdings werden auch langfristige Erfolge erzielt. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

Psoriasis vulgaris is a common and chronic inflammatory skin disease which has the potential to significantly reduce the quality of life in severely affected patients. The incidence of psoriasis in Western industrialized countries ranges from 1.5 to 2%. Despite the large variety of treatment options available, patient surveys have revealed insufficient satisfaction with the efficacy of available treatments and a high rate of medication non-compliance. To optimize the treatment of psoriasis in Germany, the Deutsche Dermatologische Gesellschaft and the Berufsverband Deutscher Dermatologen (BVDD) have initiated a project to develop evidence-based guidelines for the management of psoriasis. The guidelines focus on induction therapy in cases of mild, moderate, and severe plaque-type psoriasis in adults. The short version of the guidelines reported here consist of a series of therapeutic recommendations that are based on a systematic literature search and subsequent discussion with experts in the field; they have been approved by a team of dermatology experts. In addition to the therapeutic recommendations provided in this short version, the full version of the guidelines includes information on contraindications, adverse events, drug interactions, practicality, and costs as well as detailed information on how best to apply the treatments described (for full version, please see Nast et al., JDDG, Suppl 2:S1–S126, 2006; or http://www.psoriasis-leitlinie.de).

In order to study the spatial structure of exotic nuclei, it was proposed at the Petersburg Nuclear Physics Institute (PNPI) to measure the differential cross section for small-angle proton elastic scattering in inverse kinematics. Several experiments in beams of 0.7-GeV/nucleon exotic nuclei were performed at the heavy-ion accelerator facility of GSI (Gesellschaft für Schwerionenforschung, Darmstadt, Germany) by using the IKAR ionization spectrometer developed at PNPI. The IKAR ionization chamber filled with hydrogen at a pressure of 10 bar served simultaneously as a target and as a recoil-proton detector, which measured the recoil-proton energy. The beam-particle scattering angle was also measured.more » The results obtained for the cross sections in question were analyzed on the basis of the Glauber-Sitenko theory using phenomenological nuclear-density distributions with two free parameters. Nuclear-matter distributions and root-mean-square radii were found for the nuclei under investigation. The size of the halo in the {sup 6}He, {sup 8}He, {sup 11}Li, and {sup 14}Be nuclei was determined among other things. Information about neutron distributions in nuclei was deduced by combining the data obtained here with the known values of the radii of proton distributions. A sizable neutron skin was revealed in the {sup 8}Li, {sup 9}Li, and {sup 12}Be nuclei.« less

The reconstruction of the evolutionary history of this professional association lays its focus on the developments which contributed to the society’s formal foundation during the time of the patient killings in Germany after 1939. Methodologically the study follows strategies of historical network analysis including the main actors of the foundation process. The foundation of this society can be seen as the result of the interaction of a) the Reichs-Health-Agency, its president Hans Reiter, and Fritz Rott as National Socialist health politicians, b) the scientific development geared to this policy of a young discipline that shared its knowledge base as well as its medical ‘object’ with established specialties like psychiatry and pediatrics, c) a postulated need for character studies, prognosis and selection, and d) personal as well as professional-political interests of the main protagonists Schroeder and Villinger. Once more it is obvious that medicine and politics were not only interwoven, but in certain areas in accordance with each other. Borders could rather be established between social regulatory “instances”. The foundation of the DGKH (Deutsche Gesellschaft für Kinderpsychiatrie und Heilpädagogik; German Society for Child Psychiatry and Therapeutic Education) is an example of a ‘radical regulatory reasoning’ according to Raphael, that by means of “institutional arrangements at medium level” (Raphael, 2001) was supposed to implement the ‘new National-Socialist order’.

The antifolate agent methotrexate is routinely used for systemic therapy of cancer and chronic inflammatory diseases. Successful topical use has been described for individual therapeutic attempts, in case series, and small studies, especially for mycosis fungoides (premycotic stage) and lymphomatoid papulosis. With respect to its clinical use in selected treatment scenarios, there have been no approved preparations or regulated instructions for pharmaceutical compounding. Two high performance liquid chromatography methods were established for the determination of the active substance within a galenic formulation as well as within extracts of biological material. Suitable vehicles for epicutaneous application were developed and preclinically tested for stability, release, and pharmacokinetics of the active substance as well as their safety. The tests show that methotrexate may be readily incorporated into "Basiscreme DAC". It remains stable up to a concentration of 0.5%. This preparation releases enough active substance to achieve relevant local bioavailability in the respective target compartments of the skin. There is no evidence of safety risks due to relevant systemic bioavailability after topical application on a limited area of the skin. In summary, this approved prescription for extemporaneous preparation complies with the requirements of the German Ordinance on the Operation of Pharmacies (Article 7 ApBetrO), and the available data proves its stability and pharmaceutical quality. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

Previous classifications of vasculitides suffer from several defects. First, classifications may follow different principles including clinicopathologic findings, etiology, pathogenesis, prognosis, or therapeutic options. Second, authors fail to distinguish between vasculitis and coagulopathy. Third, vasculitides are systemic diseases. Organ-specific variations make morphologic findings difficult to compare. Fourth, subtle changes are recognized in the skin, but may be asymptomatic in other organs. Our aim was to use the skin and subcutis as a model and the clinicopathologic correlation as the basic process for classification. We use an algorithmic approach with pattern analysis, which allows for consistent reporting of microscopic findings. We first differentiate between small and medium vessel vasculitis. In the second step, we differentiate the subtypes of small (capillaries versus postcapillary venules) and medium-sized (arterioles/arteries versus veins) vessels. In the final step, we differentiate, according to the predominant cell type, into leukocytoclastic and/or granulomatous vasculitis. Starting from leukocytoclastic vasculitis as a central reaction pattern of cutaneous small/medium vessel vasculitides, its relations or variations may be arranged around it like spokes of a wheel around the hub. This may help establish some basic order in this rather complex realm of cutaneous vasculitides, leading to a better understanding in a complicated field. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

Introduction: The German DRG system is annually adapted to the changing services provided. For the further development, the self-governing body and its DRG Institute (InEK) depend on participation of the users. Methods: For one of the DRG evaluation projects initiated by DGGG, cost and performance data for the year 2011 from 16 hospitals were available. After plausibility checks and corrections, analyses for service and cost homogeneity were performed. In cases of inadequate DRG-representation attributes were sought that would make an appropriate reimbursement possible. Conspicuities and potential solutions were checked for clinical plausibility. Results: 44 concrete modification proposals for further development of the G-DRG system were formulated and submitted in due time to the InEK. In addition, 3 modification proposals were addressed to the German Institute for Medical Documentation and Information (Deutsches Institut für Medizinische Dokumentation und Information, DIMDI) for further development of the diagnosis classification ICD-10-GM. For all modification proposals care was taken to minimise misdirected incentives and to reduce the potential for disputes with the cost bearers and their auditors services in settlements. Discussion: The publication of the G-DRG system 2014 shows which modification proposals have been realised. Essentially, an appropriate redistribution of the resources among the gynaecological and obstetrics departments is to be expected. The financial pressure that is caused by the generally inadequate financing of hospitals will not be reduced by a further development of the G-DRG system.

BioRef is a versatile novel time-of-flight reflectometer featuring a sample environment for in situ infrared spectroscopy at the reactor neutron source BER II of the Helmholtz Zentrum Berlin fuer Materialien und Energie (HZB). After two years of design and construction phase the instrument has recently undergone commissioning and is now available for specular and off-specular neutron reflectivity measurements. BioRef is especially dedicated to the investigation of soft matter systems and studies at the solid-liquid interface. Due to flexible resolution modes and variable addressable wavelength bands that allow for focusing onto a selected scattering vector range, BioRef enables a broad rangemore » of surface and interface investigations and even kinetic studies with subsecond time resolution. The instrumental settings can be tailored to the specific requirements of a wide range of applications. The performance is demonstrated by several reference measurements, and the unique option of in situ on-board infrared spectroscopy is illustrated by the example of a phase transition study in a lipid multilayer film.« less
Comparison of different liquid hydrogen tank integration concepts for the ELAC-1 research configuration

One of the main problems associated with the structural design of a hypersonic aircraft is the conception of the cryogenic tank. Therefore two essential questions, in consideration of structural weight, volumetric efficiency and the aspects as well of inspection, maintenance and repair, as of exchangeability in case of leakage (leak before burst) and safety in operation, have to be answered. These questions concern the choice of the tank integration concept and the tank cross section. To get an idea how much the take-off weight depends on the tank integration concept, at the Institut fuer Leichtbau of the RWTH Aachen a program for weight estimation of hypersonic aircraft has been developed. Herewith the goal was to define well suited substitute models which allow the performance of parametric studies within a wide range of parameters in a tolerable amount of time. In the following the mass model and calculation methods used will be shortly introduced and finally the results achieved will be presented and discussed. On this occasion also comments on structural efficiency of different tank cross sections will be given.

In Germany, infections due to the zoophilic dermatophyte Trichophyton (T.) species of Arthroderma benhamiae are being more frequently diagnosed. The source of infection of this emerging pathogen overlaps with that of the zoophilic species T. interdigitale. The most common source are guinea pigs. T. species of Arthroderma benhamiae causes inflammatory dermatophytosis in children and adolescents. In addition to tinea capitis, it may cause both tinea corporis, tinea manus and frequently tinea faciei. In Germany, T. species of Arthroderma benhamiae is a frequent zoophilic dermatophyte, which in regions is probably more frequent than Microsporum canis. The mycological identification of the isolates with their yellow stained colonies is based on their macroscopic and microscopic features. However, some exhibit colony features consistent with those of T. interdigitale. These strains only can be identified unambiguously by means of molecular techniques. Using detection methods such as PCR-ELISA or real-time PCR, the dermatophyte can be identified directly from clinical material. Sequencing of the internal transcribed spacer region (ITS) of the ribosomal DNA has been approved as culture confirmation test for T. species of Arthroderma benhamiae. In addition, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) is useful. Widespread dermatophytosis due to T. species of Arthroderma benhamiae, in particular of tinea capitis, requires oral antifungal agents. Terbinafine is most effective, alternatives are fluconazole and itraconazole. © 2014 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

The influence of electromagnetic fields on the health of humans and animals is still an intensively discussed and scientifically investigated issue (Prakt Tierarzt 11:15-20, 2003; Umwelt Medizin Gesellschaft 17:326-332, 2004; J Toxicol Environment Health, Part B 12:572-597, 2009). We are surrounded by numerous electromagnetic fields of variable strength, coming from electronic equipment and its power cords, from high-voltage power lines and from antennas for radio, television and mobile communication. Particularly the latter cause's controversy, as everyone likes to have good mobile reception at anytime and anywhere, whereas nobody wants to have such a basestation antenna in their proximity. In this experiment, the NIR has resulted in changes in the enzyme activities. Certain enzymes were disabled, others enabled by NIR. Furthermore, individual behavior patterns were observed. While certain cows reacted to NIR, others did not react at all, or even inversely. The present results coincide with the information from the literature, according to which NIR leads to changes in redox proteins, and that there are individuals who are sensitive to radiation and others that are not. However, the latter could not be distinctly attributed - there are cows that react clearly with one enzyme while they do not react with another enzyme at all, or even the inverse. The study approach of testing ten cows each ten times during three phases has proven to be appropriate. Future studies should however set the post-exposure phase later on.

Given that there is no standard systemic treatment for children and adolescents with plaque psoriasis, this non-interventional, multicenter, retrospective study collected data on the efficacy and safety of long-term treatment with fumaric acid esters (FAEs) in this particular patient group. In patients younger than 18 years of age at the start of FAE treatment, data on efficacy and safety was retrospectively collected for at least 36 months. Data from 127 patients (aged 6-17 years) was collected for treatment durations of up to 60 months. Physician's Global Assessment, Psoriasis Area and Severity Index, and Body Surface Area showed marked improvement in the first six months. After 36 months, these parameters had, on average, improved by up to two-thirds of baseline values. Thirty-seven patients experienced at least one adverse event (AE), which was FAE-related in 36 individuals. Three AEs (proteinuria (one case), flushing (two cases)) persisted during the observation period while on treatment. Fifteen AEs led to the discontinuation of therapy; nearly all of these cases were related to gastrointestinal disorders. The KIDS FUTURE study - for the first time - included a larger population of children and adolescents with psoriasis who were treated with FAEs. The data obtained suggests that long-term FAE therapy in this patient group may be effective and safe. The results are currently being verified in an ongoing clinical study. © 2015 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

The median age of patients with Ewing sarcoma (EwS) at diagnosis is around 14-15 years. Older age is associated with a worse outcome. The correlation of age at diagnosis on sites of disease has not been fully described. The goal of this study was to evaluate the differences in sites of primary tumor and metastatic tumor involvement according to age groups. EwS data from the Gesellschaft für Pädiatrische Onkologie und Hämatology (GPOH) database of the Cooperative Ewing Sarcoma Study (CESS) 81/86 and the European Intergroup Cooperative Ewing's Sarcoma Study EICESS 92 and the EUROpean Ewing tumor Working Initiative of National Groups-99-Protocol (EURO-E.W.I.N.G.-99) study were analyzed. Patient and tumor characteristics were evaluated statistically using chi square tests. The study population included 2,635 patients with bone EwS. Sites of primary and metastatic tumors differed according to the age groups of young children (0-9 years), early adolescence (10-14 years), late adolescence (15-19 years), young adults (20-24 years), and adults (more than 24 years). Young children demonstrated the most striking differences in site of disease with a lower proportion of pelvic primary and axial tumors. They presented less often with metastatic disease at diagnosis. Site of primary and metastatic tumor involvement in EwS differs according to patient age. The biological and developmental etiology for these differences requires further investigations. © 2018 Wiley Periodicals, Inc.

Die Pustulosis palmoplantaris ist eine chronisch entzündliche Hauterkrankung, die mit bedeutenden Einschränkungen der Lebensqualität und der Belastbarkeit einhergeht. Aufgrund von Zulassungsbeschränkungen und einem häufig therapierefraktären Verlauf sind die Behandlungsmöglichkeiten limitiert. Nach zuvor frustranen Therapien erhielten 9 Patienten mit Pustulosis palmoplantaris nach Ausschluss einer latenten Tuberkulose Ustekinumab (45 mg Ustekinumab bei < 100 kg Körpergewicht [KG], 90 mg Ustekinumab > 100 kg KG) in Woche 0, 4, 12 und 24. Reguläre Visiten erfolgten nach 4 und 12 Wochen, im weiteren Verlauf alle 12 Wochen. Das Durchschnittsalter bei Therapiebeginn betrug 48 Jahre. Drei Patienten waren männlich. Bei n = 4 Patienten (44,4 %) wurde eine Verbesserung um 75 % des Palmoplantar-Psoriasis-Area-Severity-Index (PPPASI) erreicht. Insgesamt verbesserte sich der PPPASI nach 24 Wochen durchschnittlich um 71,6 %. Eine komplette Abheilung zeigte sich bei n = 2 Patienten nach 24 Wochen. Bis auf lokale Injektionsreaktionen und leichte Infekte wurden keine unerwünschten Wirkungen beobachtet. Die Fallserie ist ein weiterer Beleg für die Wirksamkeit und Verträglichkeit von Ustekinumab in der Therapie der Pustulosis palmoplantaris. Zur Beurteilung der Langzeitwirkung und -sicherheit sowie der Wirksamkeit einer intermittierenden Therapie sind kontrollierte Studiendaten sowie Beobachtungen im Rahmen von Patientenregistern notwendig. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Schwere Verlaufsformen der Alopecia areata (AA) im Kindesalter sind aufgrund limitierter Optionen therapeutisch herausfordernd. Systemische, hochdosierte Glukokortikoide weisen die schnellste Ansprechrate auf, nach dem Absetzen kommt es allerdings zu Rezidiven. Eine längerfristige Hochdosis-Anwendung ist aufgrund der zu erwartenden Nebenwirkungen nicht empfehlenswert. Eine dauerhafte Steroiderhaltungstherapie unterhalb der Cushing-Schwellen-Dosis nach Bolustherapie könnte die Krankheitsaktivität ohne Nebenwirkungen längerfristig unterdrücken. Im Rahmen einer offenen Anwendungsbeobachtung wurden 13 Kinder mit schweren Formen der AA in diese Studie eingeschlossen. Bei sieben Kindern lag eine AA totalis/universalis vor, bei sechs eine multifokale AA mit Befall von mehr als 50 % der Kopfhaut. Das Therapieregime sah eine initiale Prednisolon-Dosierung von 2 mg/kg Körpergeweicht (KG) vor und wurde innerhalb von neun Wochen auf eine Erhaltungsdosierung unter der individuellen Cushing-Schwelle reduziert. Der Nachbeobachtungszeitraum betrug ein bis drei Jahre. Wir beobachteten in 62 % aller Fälle ein komplettes Nachwachsen der Haare. Die mittlere Dauer bis zum Ansprechen lag bei 6,6 Wochen und konnte mit der Erhaltungstherapie über den gesamten Beobachtungszeitraum aufrechterhalten werden. An Nebenwirkungen wurden ausschließlich eine Gewichtszunahme (1-3 kg) bei allen Behandelten sowie eine milde Steroidakne in 23 % der Fälle beobachtet. Die kombinierte Hoch-/Niedrig-Dosis-Therapie mit systemischen Glukokortikoiden mittels Prednisolon zeigte eine hohe, dauerhafte Ansprechrate ohne signifikante Nebenwirkungen. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Obwohl Tätowierungen in den letzten Jahren außerordentlich beliebt geworden sind, wurde in der Literatur bisher nur über wenige Fälle schwerer Reaktionen berichtet, die zu einer malignen Transformation führten. Dies steht im Kontrast zu der praktisch unüberschaubaren Zahl an Tätowierungen weltweit. Die Zusammensetzung der für Tätowierungen verwendeten Farbstoffe variiert stark, und selbst gleiche Farbtöne können unterschiedliche Komponenten enthalten. Das Ziel unserer Studie war es zu untersuchen, auf welche Weise Tätowierungen möglicherweise Hautkrebs auslösen können. Wir berichten über den seltenen Fall einer 24-jährigen Frau, bei der sich sieben Monate nachdem sie eine Tätowierung auf dem Fußrücken erhalten hatte in unmittelbarer Nähe des verwendeten roten Farbstoffs ein Plattenepithelkarzinom entwickelte. Die Komplikationen begannen mit einer unspezifischen Schwellung. Die Läsion wurde histologisch untersucht. Die Zusammensetzung des inkorporierten Farbstoffs wurde mittels Rasterelektronenmikroskopie in Kombination mit energiedispersiver Elementanalyse analysiert. Zur weiteren Charakterisierung wurden Thermogravimetrie und Pulverdiffraktometrie eingesetzt. Der Tätowierungsfarbstoff enthielt hauptsächlich Bariumsulfat; Spuren von Al, S, Ti, P, Mg und Cl ließen sich ebenfalls nachweisen. Bei der Analyse zeigten sich Pigmentgranula unterschiedlicher Größe. In seltenen Fällen kann Tätowierungstinte karzinogene Effekte haben, die multifaktoriell zu sein scheinen. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Versorgungsregister dienen der Erfassung des Einsatzes und der Wirksamkeit von Therapien unter realen Versorgungsbedingungen und sind als Basis einer evidenzbasierten Gesundheitsversorgung unverzichtbar. Das deutsche Neurodermitis-Register TREATgermany wurde als weltweit erstes Register für Patienten mit schwerer Neurodermitis 2011 initiiert. Erwachsene mit schwerer Neurodermitis (aktuelle/frühere antientzündliche Systemtherapie und/oder objektiver SCORAD ≥ 40) werden über einen Zeitraum von 24 Monaten prospektiv beobachtet. Anhand validierter Erhebungsinstrumente werden die klinische Erkrankungsschwere (EASI, SCORAD), Lebensqualität (DLQI), Symptome, globale Erkrankungsschwere sowie die Patientenzufriedenheit erfasst und die durchgeführten Therapien dokumentiert. Die vorliegende Analyse beschreibt die Charakteristika, Therapiewahl und Wirksamkeit der eingesetzten antiinflammatorischen Systemtherapien der bis Oktober 2014 eingeschlossenen Patienten. An fünf Zentren wurden insgesamt 78 Patienten (Durchschnittsalter 39 Jahre, 61 % männlich) eingeschlossen. Bei den Patienten besteht eine hohe Inanspruchnahme ambulanter und stationärer Leistungen. Ciclosporin war das am häufigsten eingesetzte Systemtherapeutikum und zeigte die höchste klinische Effektivität (EASI-50-Ansprechrate 51 %; EASI-75-Ansprechrate 34 % nach zwölfwöchiger Therapie). Azathioprin, Methotrexat (MTX), Prednisolon oral, Mycophenolat, Alitretinoin und Leflunomid wurden ebenfalls bei einzelnen Patienten eingesetzt. Die vorliegende Registerauswertung gibt wichtige Hinweise zur derzeitigen Versorgung von Erwachsenen mit schwerer Neurodermitis in Deutschland, dokumentiert die hohe Erkrankungslast, den Nutzen vorhandener Therapien und den Bedarf an weiteren, effektiven und in der Langzeitanwendung sicheren Therapieoptionen. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Rich in tannins, the rhizome of Potentilla officinalis (PO) has traditionally been used in the topical treatment of inflammatory disorders of the skin and mucous membranes. The objective of the present study was to examine the antiinflammatory effects of PO in the UV erythema test as well as in patients with atopic skin. Using the UV erythema test, the antiinflammatory effects of a PO extract (2 %) - compared to 1 % hydrocortisone acetate - were assessed in a randomized, prospective, placebo-controlled double-blind study of 40 healthy volunteers. In the context of a prospective non-controlled trial, the efficacy and tolerability of 2 % PO cream (applied to defined test areas twice daily for two weeks) was evaluated in twelve adults and twelve children with atopic skin using a partial SCORAD. In addition, the effects on the degree of erythema in the test areas was measured photometrically. In the UV erythema test, PO cream significantly reduced the erythema index compared to the vehicle. The antiinflammatory effects of PO cream were comparable to those of 1 % hydrocortisone acetate cream. The clinical study with atopic patients revealed a significant reduction in the partial SCORAD as well as erythema in the test areas. No adverse events were recorded. PO cream displays antiinflammatory effects in vivo. It is effective in and well tolerated by patients with atopic skin. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

In den letzten sechs Jahren wurden verschiedene innovative systemische Therapien zur Behandlung des metastasierten malignen Melanoms (MM) entwickelt. Die konventionelle Chemotherapie wurde durch neuartige Primärtherapien abgelöst, darunter systemische Immuntherapien (Anti-CTLA4- und Anti-PD1-Antikörper; Zulassung von Anti-PDL1-Antikörpern erwartet) und Therapien, die gegen bestimmte Mutationen gerichtet sind (BRAF, NRAS und c-KIT). Daher stehen die behandelnden Ärzte neuen Herausforderungen gegenüber, beispielsweise der Stratifizierung von Patienten für geeignete Behandlungen und der Überwachung von Langzeit-Respondern auf Progression. Folglich werden zuverlässige Methoden zur Überwachung von Krankheitsprogression oder Behandlungsresistenz benötigt. Lokalisierte und fortgeschrittene Krebserkrankungen können zur Bildung zirkulierender Tumorzellen und Tumor-DNA (ctDNA) führen, die sich in Proben von peripherem Blut nachweisen und quantifizieren lassen (Liquid Biopsy). Im Fall von Melanompatienten können die Ergebnisse von Liquid Biopsy als neuartige prädiktive Biomarker bei therapeutischen Entscheidungen hilfreich sein, insbesondere im Zusammenhang mit mutationsbasierten zielgerichteten Therapien. Die Herausforderungen bei der Anwendung der Liquid Biopsy beinhalten strikte Kriterien für den Phänotyp der zirkulierenden MM-Zellen oder ihrer Fragmente und die Instabilität von ctDNA im Blut. In diesem Übersichtsartikel diskutieren wir die Beschränkungen der Liquid Biopsy hinsichtlich ihrer Anwendung in der Routinediagnostik. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

The species Aspergillus fumigatus was first extensively described by G. Fresenius. J. B. Georg W. Fresenius was born in Frankfurt/Main, Germany, in 1808 and also died there in 1866. He studied medicine and finished his doctorate thesis (MD) in 1829. Afterwards he started his career as a physician and surgeon in Frankfurt/Main in the same year. In 1831 Fresenius became a university lecturer for botany at the "Senckenbergisches medicinisches Institut"; this institute specialized in botany. In this year Fresenius also became the director of the botanical gardens of Frankfurt/Main. Apart from his collaboration in the institute for agriculture he actively participated in the microscopical association of Frankfurt as well as the "Senckenbergische medicinische Gesellschaft". Almost over the whole period, Fresenius also worked as a physician taking care of miserable people. The outstanding publications of Fresenius are "Die Flora von Frankfurt" (Flora of Frankfurt) and "Beiträge zur Mykologie" (Contributions to Mycology). The monograph "Beiträge zur Mykologie" was published by Fresenius as a dedication for the centennial celebrations of the Senckenberg foundation ("Senckenbergische Stiftung"). It contains 132 pages and 13 excellent lithographic figures (Camera lucida). The third part of this monograph also contains the description of the species A. fumigatus. Fresenius was an engaged physician as well as an outstanding researcher and expert in natural sciences who described numerous new fungal species some of which are still accepted nowadays in accordance with the "International Code of Botanical Nomenclature".

Die Charakterisierung der klinischen Merkmale und des biologischen Potenzials von Spitznävi hat in den letzten Jahrzehnten breites Interesse gefunden. Das Ziel dieser Arbeit ist die Beschreibung der klinischen und dermatoskopischen Merkmale von Spitznävi sowie des klinischen Ergebnisses nach chirurgischer Exzision von Spitznävi in drei pädiatrischen Altersgruppen. Restrospektive Studie zur Analyse von klinischen Merkmalen, videodermatoskopischen Bildern, histopathologischen Diagnosen und Behandlungsergebnissen. Der Grad der Pigmentierung wurde sowohl klinisch als auch histopathologisch beurteilt. Bei 71 Patienten wurden 72 spitzoide Neoplasien entfernt. Videodermatologische Bilder lagen für 41 Patienten vor. Das Muster der Pigmentierung korrelierte signifikant mit dem Alter der Patienten: Hyperpigmentierte Läsionen waren bei Vorschulkindern selten, bei Patienten von 7 bis 12 Jahren und ab 13 Jahren dagegen häufiger. Eine histopathologische Diagnose von atypischen Spitznävi wurde selten durchgeführt. Keiner der Patienten, bei denen ursprünglich ein atypischer Spitznävus diagnostiziert worden war, entwickelte ein Lokalrezidiv oder Metastasen während der anschließenden Nachbeobachtung. Pigmentierte Spitznävi traten im Alter ab 13 Jahren häufiger auf. Die Studie bestätigt andere Berichte über die Altersverteilung von Pigmentierungsmustern und hebt die geringe Anzahl atypischer Spitznävi bei pädiatrischen Patienten hervor sowie das Ausbleiben von Rezidiven bei der langfristigen Nachbeobachtung. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Recent studies reveal that glycogen synthase kinase-3β (GSK-3β) acts as a pro-inflammatory enzyme, and by inhibiting this kinase, inflammation can be controlled. In this regard, a series of 17 piperazine-linked oxazolo[4,5-b]pyridine-based derivatives was synthesized and evaluated for in vitro GSK-3β inhibitory and in vivo anti-inflammatory activity. The compounds 7d, 7e, 7g, and 7c displayed the best GSK-3β inhibitory activity among all the synthesized compounds, with corresponding IC 50 values of 0.34, 0.39, 0.47, and 0.53 µM. Among the compounds 7d, 7e, 7g, and 7c examined for in vivo anti-inflammatory activity in the rat paw edema model, compound 7d exhibited maximum inhibition, reducing the paw volume by 62.79 and 65.91% at 3 and 5 h post-carrageenan administration, respectively, in comparison to indomethacin (76.74% at 3 h and 79.54% at 5 h after carrageenan administration). Furthermore, these compounds (7d, 7e, 7g, and 7c) were also found to substantially inhibit pro-inflammatory mediators, i.e., TNF-α, IL-1β, and IL-6, ex vivo in comparison to indomethacin and did not pose any gastric ulceration risk, indicating the potential of this oxazolopyridine scaffold for the development of GSK-3β inhibitors and their application as anti-inflammatory agents. © 2017 Deutsche Pharmazeutische Gesellschaft.

Cladribine (2-CdA) is used as an anti-cancer drug but is currently studied as a potential treatment for use in relapsing-remitting multiple sclerosis (MS). In this study, we computer designed, synthesized, and characterized two novel derivatives of 2-CdA, K1-5d and K2-4c, and investigated their underlying mechanism of beneficial effect using the CCRF-CEM and RAJI cell lines. For this purpose, we first determined their effect on MS and DNA damage and repair-related gene expression profiles using custom arrays along with 2-CdA treatment at non-toxic doses. Then, we determined whether cells underwent apoptosis after treatment with 2-CdA, K1-5d, and K2-4c in CCRF-CEM and RAJI cells, using the DNA fragmentation assay. It was found that both derivatives modulated the expression of the pathway-related genes that are important in inflammatory signaling, apoptosis, ATM/ATR, double-strand break repair, and the cell cycle. Furthermore, 2-CdA, K1-5d, and K2-4c significantly activated apoptosis in both cell lines. In summary, our data demonstrate that although both derivatives act as anti-inflammatory and apoptotic agents, inducing the accumulation of DNA strand breaks and activating the ultimate tumor suppressor p53 in T and B lymphocytes, the K1-5d derivative has shown more promising activities for further studies. © 2017 Deutsche Pharmazeutische Gesellschaft.
Back to the roots - dermatology in ancient Egyptian medicine.

PubMed

Hartmann, Anke

2016-04-01

Although ancient Greek and Roman medicine is generally considered the origin of European medicine, there is evidence in ancient Egyptian texts suggesting a precursor role of ancient Egyptian medicine in this regard. What did Greek and Roman physicians learn from their Egyptian counterparts? Of the medical papyri discovered to date, the largest and most significant - the Ebers papyrus and the Smith papyrus - originate from the beginning of the New Kingdom, however, they were - at least in part - already written during the Old Kingdom. Considering the times, the spectrum of diseases treated as well as the range of conservative and surgical treatment methods was truly astounding. Taking a medical history, performing a thorough manual examination, and assessing clinical findings constituted key components in establishing a diagnosis. Apart from hygienic aspects, skin and hair disorders, the treatment of acute and chronic wounds and injuries as well as cosmetic procedures took on an important role. Even back then, physicians sought to assess inflammatory processes with respect to their cardinal features, implement graded wound therapy, and treat diseases with allopathic drugs. The 'channel theory' prevalent at that time, in which the unimpeded flow of bodily fluids was considered a fundamental prerequisite for health, may likely be regarded as precursor of ancient Greek humoral pathology. The latter became the basis for the subsequently established theory of the four humors, and was thus essential for the entire field of medieval medicine. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

In Austria a national survey was conducted by Med AUSTRON/Osterreichische Gesellschaft for Radio--Onkologie, Radiobiologie und Medizinische Radiophysik (OGRO) in order to estimate the indications, patient numbers and radiotherapy treatment planning procedures and performances at all Austrian radiotherapy institutes. Results were correlated with incidence rates (Austrian cancer registry) to determine patterns of radiotherapy practice in Austria. At 12 radiotherapy departments of Austria data of all patients receiving irradiation within a 3 months (2002/2003) period were assessed. On the basis of a questionnaire number of treated patients, indications, and parameters of disease (stage, histology) and treatment modalities were evaluated. Results were analysed with regard to different tumour groups, according to academic and non academic hospitals, and correlated with epidemiological data on cancer incidence. In total, 3783 patients were registered within this period. According to the different tumour entities percentages of patients receiving radiotherapy within initial treatment varied from 3% to 90 % (e.g. brain tumours: 77%, breast cancer: 90%, prostate cancer: 35%). The most frequent indications to radiotherapy per radiotherapy department were breast cancer (range 22%-35%; mean 26%), urological tumours (range 6%-27%; mean 12%) and bone metastases (mean 10%, range 3%-17%). In Austria breast cancer, urological tumours and bone metastases are representing the most common indications to radiotherapy. Among the different departments variations in indications to radiotherapy were observed. Our study is the first evaluation of radiotherapeutic management in Austria.

Tinea capitis is the most common type of dermatomycosis in children. Its pathogen profile shows geographic variations as well as temporal shifts. Data from 150 patients with mycologically confirmed tinea capitis treated at the Department of Dermatology, University Hospital Würzburg, between 1990 and 2014 were analyzed with respect to gender, age, and pathogen spectrum. Two time periods, each 12.5 years long, were compared. Although tinea capitis was most frequently diagnosed in children between the ages of 0 and 5, the percentage of adults (16 %) was higher than previously reported. The zoophilic dermatophyte Microsporum canis was most frequently identified as the causative agent of tinea capitis. However, there was a rise in infections caused by the anthropophilic fungi Trichophyton tonsurans and Trichophyton rubrum, and also a trend towards a lower percentage of zoophilic versus anthropophilic pathogens. Over the course of time, we observed an increase in the diversity of the pathogen spectrum. Dermatophytes such as Trichophyton soudanense, the Trichophyton anamorph of Arthroderma benhamiae, Trichophyton schoenleinii, and Microsporum audouinii were isolated either for the first time or for the first time after a long hiatus. Although Microsporum canis infections still predominate, there has been an increase in anthropophilic pathogens. Given the unexpectedly high percentage of adults, tinea capitis should be included in the differential diagnostic considerations in all age groups. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Wund-D.A.CH. is the umbrella organization of the various wound care societies in German-speaking countries. The present consensus paper on practical aspects pertinent to compression therapy in patients with venous leg ulcers was developed by experts from Germany, Austria, and Switzerland. In Europe, venous leg ulcers rank among the most common causes of chronic wounds. Apart from conservative and interventional wound and vein treatment, compression therapy represents the basis of all other therapeutic strategies. To that end, there are currently a wide variety of materials and systems available. While especially short-stretch bandages or multicomponent systems should be used in the initial decongestion phase, ulcer stocking systems are recommended for the subsequent maintenance phase. Another - to date, far less common - alternative are adaptive Velcro bandage systems. Medical compression stockings have proven particularly beneficial in the prevention of ulcer recurrence. The large number of treatment options currently available enables therapists to develop therapeutic concepts geared towards their patients' individual needs and abilities, thus resulting in good acceptance and adherence. Compression therapy plays a crucial role in the treatment of patients with venous leg ulcers. In recent years, a number of different treatment options have become available, their use and application differing among German-speaking countries. The present expert consensus is therefore meant to outline concrete recommendations for routine implementation of compression therapy in patients with venous leg ulcers. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Das Pyoderma gangraenosum (PG) ist eine seltene, inflammatorische destruktiv-ulzerierende neutrophile Erkrankung mit weitgehend unklarer Pathophysiologie. In dieser Studie wurden die potenziell relevanten Kofaktoren und Begleiterkrankungen von Patienten mit PG aus drei dermatologischen Wundzentren in Deutschland differenziert ausgewertet. Von den insgesamt 121 analysierten Patienten waren Frauen (66,9 %) häufiger betroffen als Männer. Das Alter der Patienten war 18-96 Jahre (Mittelwert [MW]: 59,8); die Wunden hatten eine Größe von 1-600 cm² (MW: 65,6 cm²) und waren überwiegend sehr schmerzhaft (VAS 1-10, MW: 7). Die Unterschenkel waren am häufigsten (71,9 %) betroffen. Bei 12 (9,9 %) Patienten bestanden chronisch entzündliche Darmerkrankungen (5,8 % Colitis ulcerosa; 4,1 % Morbus Crohn), bei 14,1 % der Patienten wurde eine Begleiterkrankung aus dem rheumatischen Formenkreis beschrieben. Neoplasien bestanden bei 20,6 % der Patienten, von denen 6,6 % als hämatologische und 14,1 % als solide Neoplasien klassifiziert wurden. Aus dem Kreis des metabolischen Syndroms wurde bei 69,4 % Patienten eine Adipositas, bei 57,9 % eine arterielle Hypertonie und bei 33,9 % ein Diabetes mellitus diagnostiziert. Diese Datenanalyse bestätigt Assoziationen des PG mit dem metabolischen Syndrom und mit Neoplasien, die zukünftig frühzeitig bei einer zielgerichteten Diagnostik der Patienten beachtet und behandelt werden sollten. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Wilhelm Ebert, born 1871 in Leipzig, did study astronomy for a short time in Geneva and afterwards in Munich where he finished his PhD. He spent most of his scientific life in France, working on problems of latitude determination and celestial mechanics, mostly at the Bureau des Longitudes in Paris. He was member of the Astronomische Gesellschaft. Probably he used some of the regular meetings of the AG to introduce his work to German astronomers - for a rather short time he worked at the observatories of Kiel, Straßburg and Greifswald. In Greifswald he qualified for giving university lectures and he started to collect astronomical instruments to establish an observatory. M. Loewy, at that time director of Paris observatory, asked him to come back to France, first he had a position at Nice Observatory and shortly afterwards in Paris again. In 1909 he decided to live in Vienna, once more he applied for the qualification of giving university lectures; this time the procedure was easy going. He announced quite a lot of courses but nobody knows if they really took place. From February 1915 until his death in November 1916 he stayed in a psychiatric hospital in Vienna suffering from a disease which was uncurable at that time. His wife tried to get some information about his death in 1937. Already at that time he was unknown to the members of Vienna Observatory.

Die Tinea capitis ist die häufigste Dermatomykose des Kindesalters. Das Erregerprofil zeigt unterschiedliche geographische Verteilungsmuster und variiert im Laufe der Zeit. Zwischen 1990-2014 an der Würzburger Universitätsklinik für Dermatologie erhobene Daten von 150 Patienten mit mykologisch gesicherter Tinea capitis wurden hinsichtlich Alter, Geschlecht und Erregerspektrum analysiert und über zwei Zeiträume von jeweils 12,5 Jahren miteinander verglichen. Obwohl eine Tinea capitis am häufigsten bei Kindern der Altersgruppe zwischen 0 und 5 Jahren diagnostiziert wurde, lag der Anteil betroffener Erwachsener mit 16 % höher als bislang berichtet. Der zoophile Dermatophyt Microsporum canis konnte am häufigsten als Erreger der Tinea capitis identifiziert werden, jedoch war ein Anstieg von Infektionen mit den anthropophilen Pilzen Trichophyton tonsurans und Trichophyton rubrum zu verzeichnen. Tendenziell sank der Anteil zoophiler im Verhältnis zu den anthropophilen Erregern. Im zeitlichen Verlauf zeigte sich eine zunehmende Heterogenität des Erregerspektrums: Dermatophyten wie Trichophyton soudanense und Trichophyton violaceum, Trichophyton anamorph von Arthroderma benhamiae sowie Trichophyton schoenleinii und Microsporum audouinii konnten erstmalig bzw. nach langer Zeit wieder erneut isoliert werden. Wenngleich Microsporum-canis-Infektionen noch dominieren, sind zunehmend anthropophile Erreger nachzuweisen. Angesichts des unerwartet hohen Anteils von Erwachsenen sollte eine Tinea capitis in allen Altersgruppen differenzialdiagnostisch in Betracht gezogen werden. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Components of oxidative hair dyes, such as p-toluylenediamine, are very potent contact sensitizers to which many consumers as well as hairdressers and their clients are commonly exposed. Based on the qualitative composition of both retail and professional haircare products as determined by package labeling (according to INCI), we conducted a survey on the exposure to active components of oxidative hair dyes in Germany. The joint occurrence of components is also discussed. Nearly all of the 20 most commonly used substances are potent or very potent contact sensitizers. Contained in 88 % of all products, p-toluylenediamine is the most common component. There are only minor differences between retail and professional products. A frequent combination of substances includes p-toluylenediamine (sulfate), resorcinol as well as m-aminophenol. However, their actual concentrations (which were not investigated in this study) may vastly differ depending on the shade of the individual hair dye. Descriptive univariate analysis reveals that the currently used patch test series "Hairdressing Chemicals", as recommended by the German Contact Allergy Research Group (DKG), does not adequately cover the spectrum of allergens consumers and professionals are exposed to. Other studies have also suggested that a number of other allergens should be tested as well. Taking into account the dynamic kinetics of oxidative hair dyes with respect to allergy development, the effects of combined simultaneous exposure to multiple allergens on the risk of sensitization requires further research. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

The guidelines aim to provide advice on the management of hand eczema (HE), using an evidence- and consensus-based approach. The guidelines consider a systematic Cochrane review on interventions for HE, which is based on a systematic search of the published literature (including hand-searching). In addition to the evidence- and consensus-based recommendation on the treatment of HE, the guidelines cover mainly consensus-based diagnostic aspects and preventive measures (primary and secondary prevention). Treatment recommendations include non-pharmacological interventions, topical, physical and systemic treatments. Topical corticosteroids are recommended as first line treatment in the management of HE, however continuous long-term treatment beyond six weeks only when necessary and under careful medical supervision. Alitretinoin is recommended as a second line treatment (relative to topical corticosteroids) for patients with severe chronic HE. Randomized control trials (RCT) are missing for other used systemic treatments and comparison of systemic drugs in "head-to-head" RCTs are needed. The guidelines development group is a working group of the European Society of Contact Dermatitis (ESCD) and has carefully tried to reconcile opposite views, define current optimal practice and provide specific recommendations, and meetings have been chaired by a professional moderator of the AWMF (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften; Association of the Scientific Medical Societies in Germany). No financial support was given by any medical company. The guidelines are expected to be valid until December 2017 at the latest. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

With respect to health care planning, it is commonly assumed that patients consult the nearest physician. In reality, however, patients frequently accept great-er efforts/expenses than necessary to see a physician. The objective of the present study was to determine under which circumstances patients were willing to accept additional efforts/expenses, and which role sociodemographic and clinical characteristics play in this regard. Data collection was carried out in the context of a multicenter cross-sectional study among office-based and hospital-affiliated (University Medical Center Hamburg-Eppendorf) dermatologists. Patients (n = 309) with psoriasis and chronic wounds were surveyed about their mobility patterns and disease severity. Data analysis was performed using descriptive and multivariate methods. The willingness to accept additional efforts/expenses is primarily determined by a physician's expertise and service portfolio. Comparing both diagnoses showed that psoriasis patients usually traveled longer distances than wound patients. Among psoriasis patients, one significant predictor for accepting additional efforts/expenses was the level of education. With regard to wound patients, key factors included wound size (severity). The present study revealed complex mobility patterns among patients, which are affected by numerous personal as well as clinical factors. Depending on the diagnosis and individual preferences, additional efforts/expenses can - among other things - be explained by disease severity. Further studies are required to obtain more conclusive data. © 2017 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Das Rhizom von Potentilla officinalis (PO) ist reich an Gerbstoffen und wird traditionell zur äußerlichen Behandlung von Entzündungen der Haut und der Schleimhäute verwendet. Ziel der vorliegenden Arbeit war die Bestätigung der antiinflammatorischen Eigenschaften von PO mittels eines UV-Erythem-Tests und einer klinischen Anwendungsstudie bei atopischer Haut. Die antiinflammatorische Wirkung eines PO-Extrakts (standardisiert auf 2 % Trockensubstanz) wurde in einer prospektiven, randomisierten, placebokontrollierten Doppelblindstudie mit 40 gesunden Erwachsenen im UV-Erythem-Test im Vergleich zu 1 % Hydrocortisonacetat untersucht. Im Rahmen einer prospektiven nicht kontrollierten Studie wurde die Wirkung und Verträglichkeit der 2 % PO-Creme an zwölf Erwachsenen und zwölf Kindern mit atopischer Haut nach Anwendung über zwei Wochen in einem definierten Testareal anhand eines Teil-SCORAD untersucht. Zusätzlich wurde die Beeinflussung der Hautrötung im Testareal photometrisch gemessen. Im UV-Erythem-Test zeigte die PO-Creme eine signifikante Reduktion des Erythemindex im Vergleich zum Vehikel. Die antiinflammatorische Wirkung des Verums entsprach der der 1 % Hydrocortisonacetat-Creme. Die klinische Studie bei Atopikern zeigte eine signifikante Abnahme des Teil-SCORAD und des Erythems im Testareal. Es wurden keine Unverträglichkeitsreaktionen beobachtet. PO als 2%ige Zubereitung besitzt entzündungshemmende Eigenschaften und ist wirksam und gut verträglich auf atopischer Haut. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

While most previous surveys on the clinico-epidemiological features of autoimmune bullous diseases (AIBDs) have predominantly focused on a single disease entity or just one disease group, there have been only few studies examining the incidence of various AIBDs. In the present study, we set out to determine the spectrum of AIBDs, to estimate the incidence of the most common AIBDs, and to examine their temporal trends in Central Serbia over a period of 20 years. We retrospectively recruited 1,161 new AIBD cases diagnosed in Central Serbia during the period from January 1991 to December 2010. The diagnosis was based on strict clinical, histological, and immunohistological evaluation. The incidence rates were: 4.35 per million population/year (pmp/year) for pemphigus, 4.47 pmp/year for pemphigoid, 1.42 pmp/year for dermatitis herpetiformis (DH), 0.25 pmp/year for linear IgA disease, and 0.08 pmp/year for epidermolysis bullosa acquisita. In the period observed, age-adjusted incidence rates significantly increased for pemphigus and particularly for pemphigoid, whereas they decreased, albeit not significantly, for DH. For the first time, our study evaluates the incidence rates of the entire spectrum of AIBDs in Serbia, and examines their temporal trends over a 20-year period. To the best of our knowledge, our finding of similar incidence rates for pemphigus and pemphigoid has previously not been reported. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Complementary and alternative medicine (CAM) is of high relevance in oncology. Only a minority of professionals feel competent in CAM. Our aim was to provide a strategy for establishing evidence-based counseling on CAM in oncology in the German health system. We performed a systematic search of the literature on patient counseling concerning CAM. Of 811 articles identified in this search 51 met our inclusion criteria. Data from these articles were analyzed and adapted to the needs of German patients by a group of experts of the DEGRO ("Deutschen Gesellschaft für Radioonkologie") and the German Cancer Society. In the next step a strategy about how to integrate evidence-based counseling on CAM at cancer centers and oncological institutions was developed. First, evidence-based recommendations on CAM counseling were derived. The core of our strategy combines two levels of information provision: level 1 will be oncologists, radiotherapists and other specialists and level 2 oncological CAM experts. The latter group will serve as trainers and backup for complicated or advanced questions and for individual counseling of patients with complex needs. Professionals in level 1 will be offered special training. Evidence-based counseling on CAM is not only possible but also mandatory in order to meet patient information needs. Our proposal would allow for integrated counseling available at all oncological institutions and guarantee a high quality. Furthermore, provision of information on two different levels allows the effective use of resources (manpower and financing).

Pemphigus vulgaris (PV) is typically treated with systemic corticosteroids and immunosuppressive agents. Avascular necrosis (AVN) of the femoral head is a well-recognized major complication of corticosteroid therapy. The characteristics of this serious complication in PV remain unknown. Uncontrolled, retrospective study of all PV-related AVN cases diagnosed at an Iranian autoimmune bullous disease clinic between 1985 and 2013. Of the 2,321 medical records of PV patients reviewed, 45 (1.93 %) cases showed femoral AVN, with 30 (66.7 %) individuals being male. The mean age at diagnosis of AVN was 47.4 ± 14.2 years. The mean interval between the diagnosis of PV and the onset of AVN was 25.3 ± 18.3 months. With the exception of eight cases (17.8 %), the majority of patients developed AVN within three years after the diagnosis of PV. The mean cumulative dose of prednisolone in patients with AVN was 13,115.8 ± 7041.1 mg. There was a strong correlation between the total prednisolone dose and the time of onset of AVN (p = 0.001). In patients with a history of alendronate intake, that interval was significantly shorter (p = 0.01). Occurring in about 2 % of patients, AVN is a serious complication of corticosteroid treatment in patients with PV, predominantly in the first three years of treatment. In individuals receiving higher doses of prednisolone, AVN tends to occur earlier. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Skin lesions with blue color are frequently excised to rule out malignancy. The objective of the present study was to investigate the significance of blue color. We retrospectively scanned dermatoscopic images for blue color and classified them according to pattern analysis. Of 1,123 pigmented skin lesions, 144 (12.8 %) showed blue color, 92 of which (63.9 %) were malignant. Among lesions with blue color, the most common benign diagnoses were nevi (n = 35, 24.3 %) and seborrheic keratoses (n = 8, 5.6 %). Of 103 (71.5 %) lesions with a structureless blue pattern, eight (7.8 %) were entirely blue and 95 (92.2 %) were partly blue, of which 81 (78.6 %) showed peripheral or patchy and 14 (13.6 %) central blue color. Most lesions with peripheral or patchy blue color were melanomas (n = 47, 58 %), whereas most lesions with central blue color were nevi (n = 9, 64.3 %). Of 28 lesions with blue clods, 17 (60.7 %) were basal cell carcinomas. With respect to malignancy, the positive predictive value of blue color was 63.9 % (95 % CI: 56.0-71.8 %). Among malignant lesions with blue color, structureless peripheral or patchy blue color is a clue for melanoma, while blue clods point to basal cell carcinoma. Pitfalls include seborrheic keratoses, which may show blue color, as well as some nevi, especially combined nevi. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Wund-D.A.CH. ist der Dachverband deutschsprachiger Fachgesellschaften, die sich mit den Thematiken der Wundbehandlung beschäftigen. Experten verschiedener Fachgesellschaften aus Deutschland, Österreich und der Schweiz haben nun einen aktuellen Konsens der Kompressionstherapie für Patienten mit Ulcus cruris venosum erstellt. In Europa ist das Ulcus cruris venosum eine der häufigsten Ursachen für chronische Wunden. Neben der konservativen und interventionellen Wund- und Venentherapie, ist die Kompressionstherapie die Basis der Behandlungsstrategien. Die Kompressionstherapie kann heute mit sehr unterschiedlichen Materialien und Systemen durchgeführt werden. Während in der Entstauungsphase insbesondere Verbände mit Kurzzugbinden oder Mehrkomponentensysteme zur Anwendung kommen, sind es anschließend überwiegend Ulkus-Strumpfsysteme. Eine weitere, bislang wenig verbreitete Alternative sind adaptive Kompressionsbandagen. Insbesondere für die Rezidivprophylaxe werden medizinische Kompressionsstrümpfe empfohlen. Durch die Vielzahl der heute zur Verfügung stehenden Behandlungsoptionen, kann für nahezu alle Patienten ein Konzept entwickelt werden, dass sich an den individuellen Bedürfnissen und Fähigkeiten orientiert und daher auch akzeptiert und durchgeführt wird. Die Kompressionstherapie ist für die Behandlung von Patienten mit Ulcus cruris venosum essentiell. In den letzten Jahren sind viele verschiedene Therapieoptionen verfügbar, die in den deutschsprachigen Ländern unterschiedlich angewendet oder durchgeführt werden. Daher soll dieser Expertenkonsens dazu beitragen, konkrete Empfehlungen für die praktische Durchführung der Kompressionstherapie von Patienten mit Ulcus cruris venosum darzustellen. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Zur Wirksamkeit von Aknetherapien und deren Auswirkungen auf die Lebensqualität erwachsener Patienten liegen kaum Daten vor. ZIEL: Erhebung der Wirkung von Azelainsäure 20 % Creme (Skinoren ® ) auf Akne-Schweregrad und krankheitsbedingte Lebensqualität. Nichtinterventionelle Studie bei erwachsenen Patientinnen mit leichter bis mittelschwerer Akne. Wirksamkeitsparameter waren DLQI sowie Akne-Schweregrad im Gesicht, am Dekolleté sowie am Rücken im Gesamturteil des Prüfarztes (IGA-Skala: Grad 1 = annähernd reine Haut; 2 = leichte Akne; 3 = mittelschwere Akne). Visiten waren zu Studienbeginn sowie nach 4-8 und zwölf Wochen geplant. Von den 251 eingeschlossenen Patientinnen lag zu Studienbeginn bei 59 %, 31 % bzw. 10 % ein IGA-Grad von 1, 2 bzw. 3 vor; die am häufigsten betroffene Hautpartie war das Gesicht (IGA-Grad 2 oder 3: 79 %). Nach zwölf Behandlungswochen war eine signifikante Besserung der Acne vulgaris im Gesicht (IGA-Grad 0 oder 1: 82 %) sowie auf Dekolleté und Rücken feststellbar. Der mediane DLQI-Wert sank von neun zu Studienbeginn auf fünf nach zwölf Behandlungswochen. Neunzig Prozent der behandelnden Ärzte und Patientinnen beurteilten die Verträglichkeit der Behandlung als sehr gut oder gut. Die Anwendung von 20%iger Azelainsäure-Creme führt bei erwachsenen Frauen zu einer signifikanten Besserung der Acne vulgaris und der krankheitsbedingten Lebensqualität. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Die Psoriasis-Arthritis (PsA) gehört zu den chronisch entzündlichen Gelenkerkrankungen. Trotz zahlreicher versorgungswissenschaftlicher Studien in Deutschland liegen zur pharmazeutischen Versorgungssituation von PsA-Patienten bisher kaum aktuelle Ergebnisse vor. Mit Hilfe einer systematischen Literaturrecherche sowie anhand von Routinedaten der Allgemeinen Ortskrankenkasse (AOK) Rheinland/Hamburg wird ein aktueller Überblick über die pharmazeutische Versorgung von PsA-Patienten in Deutschland gegeben. Selektiert wurden Versicherte aus dem ambulanten und stationären Bereich, die im 1. und 2. Quartal des Jahres 2014 die gesicherte Abrechnungsdiagnose Psoriasis-Arthritis L40.5+ aufwiesen. Anschließend wurden auf Basis dieser "vorab definierten" Kohorte die Arzneimitteldaten für 5 Jahre (01.01.2010-31.12.2014) abgerufen. Es konnten insgesamt n = 3205 Versicherte (45 % männlich, 55 % weiblich) der AOK Rheinland/Hamburg mit einer gesicherten PsA-Diagnose selektiert werden. Das Durchschnittsalter betrug 58,9 Jahre. 53,7 % der PsA-Patienten wurden mit systemischen PsA-relevanten Arzneimitteln versorgt. Nichtsteroidale Antirheumatika (NSAR) wurden am häufigsten verordnet, gefolgt von systemischen Glucocorticoiden. Von den selektierten PsA-Patienten, die eine Systemtherapie erhielten, wurden 72,1 % mittels einer Disease-modifying-antirheumatic-Drug (DMARD)-Monotherapie behandelt, gefolgt von der Kombinationstherapie aus DMARDs und Biologika (20,9 %). Die pharmakologische Therapie der PsA muss eine Gewährleistung zwischen adäquater Versorgung der PsA mit Verhinderung der Krankheitsprogression und ökonomischer Verantwortung darstellen. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

In Deutschland wenden 40-90 % aller Krebspatienten Methoden der komplementären and alternativen Medizin (KAM) an. Bis dato gibt es kein Datenmaterial zum Einsatz der KAM bei Melanompatienten. Das Ziel unserer Studie war es, Daten über den Gebrauch, die Informationsquellen und Ziele von Patienten mit metastasierendem Melanom zu erfassen. Einhundertsechsundfünfzig Patienten aus 25 Studienzentren nahmen an der DecOG-MM-PAL Multibasket Studie teil. Die beteiligten Personen wurden auch gebeten, an einer Nebenstudie teilzunehmen, die ihren Gebrauch von KAM erfassen sollte. Dazu wurde während der Behandlung ein standardisierter Fragebogen zu genau festgelegten Zeitpunkten ausgeteilt. Insgesamt gingen 55 Fragebögen von 32 (21 %) Melanompatienten ein. Von diesen gaben 17 (53 %) ein Interesse an KAM an, und sieben (22 %) machten von KAM Gebrauch. Die Hauptinformationsquellen (31 %) waren Familienmitglieder und Freunde, gefolgt von Ärzten (19 %). Die Hauptgründe für die Anwendung von KAM waren die Stärkung des Immunsystems (41 %) und des Körpers (34 %). Nahrungsergänzungsmittel (Vitamine und Spurenelemente) wurden am häufigsten angewendet (28 %). Eine relativ hohe Anzahl an Patienten mit metastasierendem Melanom machte trotz Teilnahme an einer klinischen Studie von KAM Gebrauch. Wechselwirkungen könnten durch biologisch basierte KAM auftreten, und hier besonders bei immunmodulierenden KAM- Strategien. Um Risiken zu vermeiden, sollte die Kommunikation zwischen den Ärzten und den Patienten verbessert werden. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Kongenitale melanozytäre Nävi (KMN) bedeuten für Patienten und Familien eine psychologische Belastung und bergen zudem medizinische Risiken. Das 2005 gegründete deutschsprachige KMN-Register wurde nun einer Zwischenauswertung bezüglich des Krankheitsverlaufes, der medizinischen Versorgung und der Lebensqualität unterzogen. 100 Patienten, die sich in den Jahren 2005 bis 2012 mit einem Erstmeldebogen registriert hatten, wurde im Rahmen einer prospektiven Kohortenstudie Anfang 2013 ein Folgemeldebogen zugesandt. Außerdem wurden mithilfe standardisierter Fragebögen Daten zu Lebensqualität (dermatology life quality index, DLQI) und Stigmatisierungserfahrungen (perceived stigmatization questionnaire, PSQ; social comfort questionnaire, SCQ) erhoben. 83 % der Patienten oder deren Eltern antworteten (Altersdurchschnitt 11,2 Jahre, Median 6 Jahre; mittleres Follow-up 4,4 Jahre). Im Gesamtkollektiv wurden vier Melanome diagnostiziert, davon zwei zerebrale Melanome im Kindesalter, ein kutanes Melanom im Erwachsenenalter und eines, das sich als proliferierender Knoten erwies. Bei vier Kindern wurde eine neurokutane Melanozytose festgestellt, drei davon mit neurologischer Symptomatik. Chirurgisch behandelt wurden 88 % (73/83). Achtundsiebzig Prozent der Befragten berichteten eine geringe oder keine Beeinträchtigung der Lebensqualität. Die wahrgenommene Stigmatisierung beziehungsweise Beeinträchtigung des sozialen Wohlbefindens war generell ebenfalls gering. Die Ergebnisse geben einen Überblick über die Situation von Patienten mit KMN in Deutschland, Österreich und der Schweiz. Ein Melanom entwickelte sich in 3 %, eine ZNS-Beteiligung bestand in 4 % der Fälle. © 2017 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Der Nachweis metastatischer Infiltrate im Sentinel-Lymphkoten (SLN) gilt als wesentlicher prognostischer Faktor des Melanoms. Alternativ zur Farbstoffmethode mit Patentblau zum Goldstandard der SLN-Biopsie (SLNB) mittels Radiokolloid wird die fluoreszenzoptische Darstellung mit Hilfe von Indocyaningrün (ICG) und Nahinfrarot (NIR)-Kamerasystem kommuniziert. Im Vergleich zur konventionellen Methode wurde die Wertigkeit des ICG-/NIR-Verfahrens in Abhängigkeit vom Body-Mass-Index (BMI) des Patienten und der Konzentration von ICG bezüglich der Visualisierung des Lymphabstroms und des SLNs untersucht. An zehn Patienten wurde die SLNB mittels Technetium-99m, Patentblau und ICG durchgeführt. Die Fluoreszenz-Darstellung von Lymphbahnen und SLN erfolgte in Echtzeit mittels der NIR-Kameratechnik "FOVIS". Je nach erzielter Bildqualität wurde ICG in einer Dosis von 0,25 mg bis 2,5 mg intrakutan appliziert. Neun der zehn SLN wurden fluoreszenzoptisch identifiziert (90 %), alle zehn radioaktiv (100 %), nur acht (80 %) mittels ICG-Grünfärbung bzw. Patenblau-Markierung. Transdermal wurde ein SLN dargestellt (10 %). In Korrelation zum BMI waren höhere ICG-Mengen, bis zu 2,5 mg intrakutan absolut, in der Darstellung der Lymphbahnen von Vorteil. Die SLN-Fluoreszenzmarkierung mit dem ICG/NIR-Kamera-System "FOVIS" stellt eine sichere Alternative zur Farbstoffmethode mit Patentblau ergänzend zur Radiokolloidmethode mit Technetium-99m dar. Weitere Studien zur optimalen Dosierung von ICG und transdermalen Bildgebung in Relation zum BMI sind notwendig. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Despite the increasing interest in medical education in the German-speaking countries, there is currently no information available on the challenges which medical educators face. To address this problem, we carried out a web-based survey among the members of the Association for Medical Education (Gesellschaft für medizinische Ausbildung, GMA). A comprehensive survey was carried out on the need for further qualifications, expertise and the general conditions of medical educators in Germany. As part of this study, the educators were asked to list the three main challenges which they faced and which required urgent improvement. The results were analysed by means of qualitative content analysis. The questionnaire was completed by 147 of the 373 members on the GMA mailing list (response rate: 39%). The educators named a total of 346 challenges and emphasised the following areas: limited academic recognition for engagement in teaching (53.5% of educators), insufficient institutional (31.5%) and financial support (28.4%), a curriculum in need of reform (22.8%), insufficient time for teaching assignments (18,9%), inadequate teacher competence in teaching methods (18.1%), restricted faculty development programmes (18.1%), limited networking within the institution (11.0%), lack of teaching staff (10.2%), varying preconditions of students (8.7%), insufficient recognition and promotion of medical educational research (5.5%), extensive assessment requirements (4.7%), and the lack of role models within medical education (3.2%). The medical educators found the biggest challenges which they faced to be limited academic recognition and insufficient institutional and financial support. Consequently, improvements should be implemented to address these issues.

Informationen zur Häufigkeit von Arzneimittelwechselwirkungen und unerwünschten Arzneimittelwirkungen zu präsentieren und Hilfestellung zu leisten, wie diese wichtigen Probleme in der pharmakologischen Behandlung stationärer dermatologischer Patienten minimiert werden können. Die Medikation von 1 099 stationären dermatologischen Patienten wurde retrospektiv mittels einer Internet-basierten Software für Medikamenteninteraktionen (Diagnosia ® Check) auf Arzneimittelwechselwirkungen und unerwünschte Arzneimittelwirkungen analysiert. Wir beschreiben eine Gesamthäufigkeit relevanter Arzneimittelwechselwirkungen von 51,7 % mit durchschnittlich 3,2 Interaktionen pro betroffenem stationären Patienten. Arzneimittelkombinationen, die gemieden werden sollten, wurden bei 5,7 % der Studienpopulation festgestellt. Der wichtigste Risikofaktor war die Gesamtzahl der verabreichten Medikamente. Die Arzneimittelgruppen, die bei der Mehrzahl der Wechselwirkungen beteiligt waren, waren Analgetika, Herz-Kreislauf-Medikamente und gerinnungshemmende Medikamente sowie Antidepressiva. Das Risiko unerwünschte Arzneimittelwirkungen auszubilden wurde bei 53,1 % der stationären Patienten als "hoch" eingestuft. Die fünf wichtigsten unerwünschten Nebenwirkungen in dieser Patientengruppe waren Blutungen, Obstipation, anticholinerge Effekte, Sedierung und orthostatische Effekte. Potenzielle Arzneimittelwechselwirkungen sowie unerwünschte Arzneimittelwirkungen sind bei stationären dermatologischen Patienten alarmierend häufig. Bei jedem zweiten Patienten besteht die Gefahr, derartige Wechselwirkungen oder unerwünschte Nebenwirkungen zu erleiden und jeder zwanzigste Patient erhält eine Arzneimittelkombination, die nicht verabreicht werden sollte. Erhöhte Wachsamkeit ist erforderlich, um die gefährdeten Patienten zu erkennen. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

The growing incidence of nearly all types of skin cancer can be attributed to increased exposure to natural or artificial ultraviolet (UV) radiation. However, there is a scarcity of statistical data on risk behavior or sunscreen use, which would be important for any prevention efforts. Using the search engine Google ® , we analyzed search patterns for the terms Solarium (tanning bed), Sonnencreme (sunscreen), and Sonnenschutz (sun protection) in Germany, Austria, and Switzerland between 2004 and 2016, and compared it to search patterns worldwide. For this purpose, "normalized search volumes" (NSVs) were calculated for the various search queries. The corresponding polynomial functions were then compared with each other over the course of time. Since 2001, there has been a marked worldwide decrease in the search queries for tanning bed, whereas those for sunscreen have steadily increased. In German-speaking countries, on the other hand, there have - for years - consistently been more search queries for tanning bed than for sunscreen. There is an annual periodicity of the queries, with the highest NSVs for tanning bed between March and May and those for sunscreen in the summer months around June. In Germany, the city-states of Hamburg and Berlin have particularly high NSVs for tanning bed. Compared to the rest of the world, German-speaking countries show a strikingly unfavorable search pattern. There is still great need for education and prevention with respect to sunscreen use and avoidance of artificial UV exposure. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Gallwitz, B; Kusterer, K; Hildemann, S; Fresenius, K

2014-12-01

Modern antidiabetic therapies should achieve low HbA1c values and avoid hypoglycaemic complications. The registry SIRTA included 1522 patients with type II diabetes mellitus (T2DM) from 306 German medical practices. Patients had an HbA1c > 6.5% under the maximum tolerated metformin dose. If required, they received combination therapy with other antidiabetics according to the guideline of the German Diabetes Society [Deutsche Diabetes Gesellschaft (DDG)] or usual medical practice. Patients were followed up for 6 months. The target criteria included the achievement of HbA1c target values and the emergence of severe hypoglycaemic episodes. Most patients (64.0%) were planned to achieve an HbA1c target < 6.5%, the standard target recommended by the 2009 DDG guideline valid throughout the registry. Primarily to reduce the individual risk for hypoglycaemia, 32.4% of patients had a less strict HbA1c-target of 6.5-7.0%. These targets were achieved by 31.3% and 44.3% of patients, respectively. Combination therapies increased from 45% to 56% over the 6 months registry. Four patients had severe hypoglycaemias (0.26%). The registry confirms results from other epidemiologic studies on the therapy of T2DM in everyday practice. The treatment strategies applied effectively reduced blood glucose and avoided severe hypoglycaemias. An early therapy of insufficiently controlled patients with T2DM is important, as lower baseline values facilitated achieving HbA1c targets. © 2014 The Authors.

In der letzten Zeit wurden in der Literatur vermehrt erhöhte Hauttoxizitäten während einer Kombinationstherapie mit BRAF Inhibitoren und Radiotherapie beschrieben. Wir berichten über sieben Melanompatienten in einem nicht resezierbaren Stadium III oder IV, die eine kombinierte Behandlung aus Bestrahlung und BRAF-Inhibitor erhielten. Bei allen Patienten konnte durch die Kombinationstherapie ein gutes lokales Ansprechen erreicht werden. Nur bei zwei Patienten wurde eine schwere Radiodermatitis (CTCAE Grad 3 bzw. 4) beobachtet. Bei diesen Patienten, die beide Vemurafenib erhielten, trat die Radiodermatitis nach ein bzw. zwei Wochen auf und resultierte in einer Unterbrechung der BRAF-Inhibitor Behandlung.. Die kumulative Dosis bis zum Zeitpunkt der Strahlendermatitis betrug 10 Gy bzw. 35 Gy. Bei allen anderen Vemurafenibpatienten konnten nur milde Reaktionen im Sinne einer Radiodermatitis CTCAE Grad 2, beim Dabrafenibpatienten CTCAE Grade 1 diagnostiziert werden. Bei einem Patienten wurde eine Recalldermatitis nach 14 Tagen einer beendeten Strahlentherapie mit einer kumulativen Dosis von 30 Gy diagnostiziert. Schwere Toxizitätsreaktionen der Haut unter einer BRAF-Inhibitionen treten nicht häufig auf und sind meistens gut therapierbar. Deshalb sollte die Kombinationstherapie bei aggressiv wachsenden Melanomen eine Therapieoption bleiben. Obwohl ein erhöhtes Risiko der Hauttoxizität unter einer Kombinationstherapie von Radiatio und BRAF-Inhibitoren besteht, wird diese von den meisten Patienten gut toleriert. Sequenzielle Therapie anstelle von gleichzeitiger Behandlung scheint die Toxizitätreaktionen nicht zu verhindern. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Die Entwicklungen im Bereich dermatologischer Laser, hochenergetischer Blitzlampen, LED und neuer Energie- und Strahlquellen der letzten Jahre haben gezeigt, dass mit neuen Wellenlängen, Konzepten und Kombinationen zusätzliche, zum Teil über den ästhetischen Bereich hinaus gehende therapeutische Optionen für den Dermatologen erschlossen werden konnten. Wurden bisher zum Beispiel mit fraktionalen Lasern Falten behandelt, sind eben diese Systeme heute in Kombination mit Medikamenten wichtige Werkzeuge bei der Behandlung von Narben, bei Feldkanzerisierung und epithelialen Tumoren. Die Anforderungen an den die Indikation stellenden und vorzugsweise therapierenden Arzt steigen mit der immer komplexer werdenden Technik und den zunehmenden Komorbiditäten und Komedikationen einer älter werdenden Patientenklientel. Parallel etabliert wurden, zunächst für einige wenige Indikationen, Geräte für die Heimanwendung, die sich durch geringe Leistung und spezielle Sicherheitsvorkehrungen zur Vermeidung von Unfällen, Risiken und Nebenwirkungen auszeichnen. Trotz der reduzierten Effizienz solcher Selbstbehandlungsmaßnahmen steigt die Wahrscheinlichkeit einer Fehlanwendung, da die Grundvoraussetzung für eine korrekte Therapie, nämlich die exakte Diagnose und Indikationsstellung, nicht vorausgesetzt werden kann. Bei einer Haarentfernung können so Pigmenttumoren, bei einer Faltentherapie neoplastische Hautveränderungen adressiert und zu erwartende, unvorhergesehene und neue Nebenwirkungen und Komplikationen induziert werden. In diesem Szenario ist es wichtig, alle potenziellen Anwender dieser neuen Technologien vor deren Einsatz so zu qualifizieren, dass den Therapierten maximale Therapiesicherheit bei höchster Effizienz unter dem Leitbild diagnosis certa - ullae therapiae fundamentum garantiert wird. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

The large hadron collider (LHC) will allow for collision between two 7TeV/c proton beams, each comprising 2808 bunches with 1.1×1011 protons per bunch, traveling in opposite direction. The bunch length is 0.5ns and two neighboring bunches are separated by 25ns so that the duration of the entire beam is about 89μs. The beam power profile in the transverse direction is a Gaussian with a standard deviation of 0.2mm. The energy stored in each beam is about 350MJ that is sufficient to melt 500kg of copper. In case of a failure in the machine protection systems, the entire beam could impact directly onto an accelerator equipment. A first estimate of the scale of damage resulting from such a failure has been assessed for a solid copper target hit by the beam by carrying out three-dimensional energy deposition calculations and two-dimensional numerical simulations of the hydrodynamic and thermodynamic response of the target. This work has shown that the penetration depth of the LHC protons will be between 10 and 40m in solid copper. These calculations show that material conditions obtained in the target are similar to those planned for beam impact at dedicated accelerators designed to study the physics of high-energy-density states of matter, for example, the Facility for Antiprotons and Ion Research at the Gesellschaft für Schwerionenforschung, Darmstadt [W. F. Henning, Nucl. Instrum Methods Phys. Res. B 214, 211 (2004)].

This manuscript reports the consensus recommendations on screening and diagnosis of Lynch syndrome (LS) in patients with endometrial or ovarian cancer as well as on possible preventive measures in effectively LS-diagnosed women. The recommendations are issued by the Austrian Arbeitsgemeinschaft für Gynäkologische Onkologie (AGO) of the Österreichischen Gesellschaft für Gynäkologie und Geburtshilfe (OEGGG) after consultation of the most recent and relevant literature and following deliberation by the Genetic Task-Force convoked May, 2015 by the AGO Council. The Austrian AGO recommends immunohistochemical tissue screening for type-I and type-II endometrial cancers in all patients below the age of 70 years, and for all endometrioid and clear-cell ovarian cancers independently of the patient's age. If needed immunohistochemistry should be complemented by tissue MLH1 promotor hypermethylation testing and/or microsatellite instability (MSI) analysis. The diagnosis LS requires confirmation through identification of a germline mutation by a molecular genetic examination in the mismatch repair genes using the patient's blood. This should be performed without preceding tissue screening when in LS-associated cancer patients the family history fulfills the Amsterdam II or the revised Bethesda criteria. In LS-diagnosed women, the age for prophylactic surgery should be set flexibly based on an informed consent. Regarding the monitoring of these women, chemo-preventive measures as well as screening procedures either to avoid or to early detect LS-related tumors are discussed with a special light on their specific limitations.
Ecological hierarchies and self-organisation - Pattern analysis, modelling and process integration across scales

2010-01-01

A continuing discussion in applied and theoretical ecology focuses on the relationship of different organisational levels and on how ecological systems interact across scales. We address principal approaches to cope with complex across-level issues in ecology by applying elements of hierarchy theory and the theory of complex adaptive systems. A top-down approach, often characterised by the use of statistical techniques, can be applied to analyse large-scale dynamics and identify constraints exerted on lower levels. Current developments are illustrated with examples from the analysis of within-community spatial patterns and large-scale vegetation patterns. A bottom-up approach allows one to elucidate how interactions of individuals shape dynamics at higher levels in a self-organisation process; e.g., population development and community composition. This may be facilitated by various modelling tools, which provide the distinction between focal levels and resulting properties. For instance, resilience in grassland communities has been analysed with a cellular automaton approach, and the driving forces in rodent population oscillations have been identified with an agent-based model. Both modelling tools illustrate the principles of analysing higher level processes by representing the interactions of basic components.The focus of most ecological investigations on either top-down or bottom-up approaches may not be appropriate, if strong cross-scale relationships predominate. Here, we propose an 'across-scale-approach', closely interweaving the inherent potentials of both approaches. This combination of analytical and synthesising approaches will enable ecologists to establish a more coherent access to cross-level interactions in ecological systems. ?? 2010 Gesellschaft f??r ??kologie.

To deduce structural trends in neurosurgery in Germany by comparison of data derived from polls conducted by the Deutsche Gesellschaft für Neurochirurgie (DGNC) in 1997, 2003 and 2008. The questionnaires of the different polls probed a comparable set of issues. The data from the responding sample were extrapolated to the nationwide average or sum and compared between the different time periods. The number of identified neurosurgical departments increased from 146 to 201 during the years 1997-2008 largely as a result of the new foundation of numerous private groups. Nationwide total neurosurgical bed capacity and intensive care unit bed capacity increased modestly over the time period. The extrapolated total number of neurosurgical operations increased from 196,341 to 319,295. Although cranial and spinal neurosurgery remain the dominant subspecialties, the number of functional neurosurgical procedures and operations for pain increased more than proportionally. Outpatient procedures were established during the time period and corresponded in 2008 to a substantial proportion of the surgical volume. The total number of residents and board-certified neurosurgeons increased during the period 1997-2008 from 1513 to 1961. The proportion of residents decreased during 1997-2003 and then increased again. The number of neurosurgical operations increased in Germany proportionally to the economic growth of other service branches over the time period. Private organizations developed more than neurosurgical departments at university and other general hospitals. Work density measured as operations per physician increased during the period 1997-2008.

Das Projekt "Nationales Krebshilfe-Monitoring zur Solariennutzung" (National Cancer Aid Monitoring of Tanning Bed Use, NCAM) ist eine deutsche Großstudie mit dem Ziel, die wichtigsten Risikofaktoren für Hautkrebs zu beobachten: natürliches Sonnenlicht und künstliche UV-Strahlung. NCAM ist eine bundesweite Querschnittstudie mit zunächst vier Runden der Datenerfassung (sogenannten Wellen) zwischen 2015 und 2018. Jedes Jahr wird eine bundesweit repräsentative Stichprobe aus 3.000 Personen im Alter von 14 bis 45 Jahren befragt. Die Querschnittsbefragung wird durch eine Kohorte von n = 450 aktuellen Solariennutzern ergänzt. Die erste Welle im Jahr 2015 ergab eine Gesamtprävalenz der Solariennutzung von 29,5 %. Elf Prozent aller Teilnehmer hatten in den vergangenen zwölf Monaten ein Solarium genutzt. Zu den Determinanten der aktuellen Solariennutzung gehörten jüngeres Alter, weibliches Geschlecht und Vollzeit-/Teilzeitbeschäftigung. Die hauptsächlichen Beweggründe, die für die Nutzung eines Solariums genannt wurden, waren Entspannung und Attraktivitätssteigerung. NCAM ist weltweit die erste Studie zur Überwachung der Risikofaktoren für Hautkrebs in jährlichen Intervallen anhand einer großen, landesweit repräsentativen Stichprobe. Erste Ergebnisse deuten darauf hin, dass Millionen Deutsche trotz Warnungen der WHO Solarien nutzen, und dass viele dieser Nutzer Jugendliche sind - trotz gesetzlicher Beschränkungen, die das Ziel haben, die Nutzung von Solarien durch Minderjährige zu verhindern. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

We provide new observations of the LMC X-1 O star and its extended nebula structure using spectroscopic data from VLT/UVES as well as Hα imaging from the Wide Field Imager on the Max Planck Gesellschaft/European Southern Observatory 2.2 m telescope and ATCA imaging of the 2.1 GHz radio continuum. This nebula is one of the few known to be energized by an X-ray binary. We use a new spectrum extraction technique that is superior to other methods used to obtain both radial velocities and fluxes. This provides an updated spatial velocity of ≃ 21.0 +/- 4.8 km s-1 for the O star. The slit encompasses both the photo-ionized and shock-ionized regions of the nebula. The imaging shows a clear arc-like structure reminiscent of a wind bow shock in between the ionization cone and shock-ionized nebula. The observed structure can be fit well by the parabolic shape of a wind bow shock. If an interpretation of a wind bow shock system is valid, we investigate the N159-O1 star cluster as a potential parent of the system, suggesting a progenitor mass of ˜60 M ⊙ for the black hole. We further note that the radio emission could be non-thermal emission from the wind bow shock, or synchrotron emission associated with the jet-inflated nebula. For both wind- and jet-powered origins, this would represent one of the first radio detections of such a structure.

Religiös-spirituelles Wohlbefinden ist verbunden mit höherer Vitalität und verminderter Depressionsneigung. In unserer Studie untersuchten wir die Strategien zur Krankheitsbewältigung und die Rolle von Religiosität-Spiritualität (R-S) zur Verbesserung des subjektiven Wohlbefindens. 149 Patienten (107 Frauen), 44 mit systemischer Sklerodermie (SKL), 48 mit Lupus erythematodes (LE) und 57 mit malignem Melanom (MM), Stadium I-II, wurden mittels eines selbstentwickelten Fragebogens zum subjektiven Wohlbefinden, zu den mit der Erkrankung einhergehenden Umständen sowie mit dem Multidimensionalen Inventar (MI-RSB) zu R-S befragt. LE-Patienten sind zum Zeitpunkt der Diagnosestellung stärker belastet als SKL- und MM-Patienten. SKL- und LE-Patienten können erst nach Jahren die Erkrankung akzeptieren. Der Gesamtscore des religiös-spirituellen Befindens liegt bei LE-Patienten signifikant unter dem Wert der Normalbevölkerung. Fotosensitivität und Gelenksschmerzen sind bei LE-Patienten negativ assoziiert mit der Fähigkeit Vergeben zu können. SKL-Patienten mit Gesichtsveränderungen und Lungenbeteiligung zeigen höhere allgemeine Religiosität. MM-Patienten haben höhere Werte für transzendente Hoffnung. Vorträge über die Krankheit und psychologische Betreuung sind die wichtigsten Bedürfnisse von Patienten mit SKL, LE und MM an ihre Betreuer. Religiös-spirituelle Angebote zur Krankheitsverarbeitung scheinen derzeit eine untergeordnete Rolle zu spielen, könnten aber eine wichtige Ressource sein, der man in Zukunft mehr Aufmerksamkeit schenken sollte. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Background: In 2012 a pilot project «recruiting qualified employees for the elderly care sector» commissioned by the German Federal Ministry of Economics and Energy (BMWi) with Vietnam was initiated. 150 Vietnamese candidates with degrees in nursing were recruited and participated in a German language course in Hanoi for six months (level A2). 100 project participants then arrived in Germany in September 2013 and started a (shortened) 2-year training in elderly care at locations in four federal states. The aim was for the Vietnamese to work in German nursing homes for at least three years after completion of the training. The project was implemented by the GIZ Gesellschaft für Internationale Zusammenarbeit and evaluated by the IEGUS Institute for European Healthcare Research and Social Economy from January 2013 to March 2016. Aim: The aim was to explore the possibilities for training of young people from emerging markets to become geriatric nurses in Germany. The results have been used as a foundation for recommendations for companies within the social care sector. Method: The formative and summative evaluation was based on personal interviews, telephone and written questionnaires, consultations and observations. The contribution presents results of the interviews and questionnaires. All relevant stakeholders had been included: The Vietnamese, the nursing and language schools, the nursing providers and mentors. Results: This article summarizes the results of the project evaluation. It gives a first insight into the experiences made from a professional, cultural as well as linguistic point of view.
[German neurology and neurologists during the Third Reich: exemplified by research on epilepsy].

There are only a small number of studies dealing with the impact of eugenic theories and practices on the research of particular neurological diseases during the Third Reich. Thus, this contribution to the special issue on neurology in Germany between 1933 and 1945 focuses exemplarily on epilepsy research. By drawing on primary sources and secondary literature the article tries to reconstruct the scientific discourse of the time and consider the implications for patients. National socialistic ideology was based on eugenic thinking and the implementation of eugenic policies was a major political objective. An immediate effect of this policy was the passing of the Law for the Prevention of Genetically Diseased Offspring (Gesetz zur Verhütung erbkranken Nachwuchses) in 1933. According to this law "hereditary epilepsy" along with various other neurological and psychiatric disorders was regarded as a mandatory indication for forced sterilization. Subsequently, funding of epileptological research was generously increased and extended, e. g. at the German Research Institute (Deutsche Forschungsanstalt) in Munich and the Rheinische Provinzial-Institut in Bonn. The main focus was placed on idiopathic forms of the disease, which were a priori considered as hereditary. At the annual meetings of the Society of German Neurologists and Psychiatrists (Gesellschaft deutscher Neurologen und Psychiater), lectures and debates on epilepsy repeatedly constituted a key topic. Some participants opted for a broad interpretation of "endogeneity" and thus favored an extension of the practice of sterilization but others advocated a more differentiated and restricted attitude. Several neurology researchers showed a penchant for self-mobilization in line with the doctrine of the new government.
Argan woodlands in South Morocco as an area of conflict between degradation and sustainable land use

Kirchhoff, Mario; Kagermeier, Andreas; Ries, Johannes B.

2016-04-01

The Argan woodlands are endemic for South Morocco and prone to degradation through expanding and intensifying agriculture and overgrazing. Unvegetated areas extend further due to degradation of soil and vegetation. Here infiltration is less than on vegetated areas, while runoff and soil erosion increase. The sale of the highly valuable oil, gained from the seeds of the argan tree, can be seen as an economic alternative for the region and a chance of survival for the argan woodlands. With the introduction of women's cooperatives for the production and sale of the oil, the Gesellschaft für Technische Zusammenarbeit (GTZ, Association for Technical Cooperation) hoped to halt argan degradation from 1995 to 2002. The effects of this approach shall be studied in a proposed DFG-project. The erosion gradient between soils under canopy cover and intertree areas in varying stages of degradation will be at the center of the analysis. Insight into onsite and offsite degradation shall be gained through the measurement of runoff and erosion rates, which lead to rill and gully erosion downslope. Measurements of soil chemical and physical properties might also help indicate when an argan woodland can be classified as natural. Furthermore to be studied are the effects of the new found value of the Argan woodlands among the local population with focus on regional tourism and a possible reduction of grazing pressure. Sustainable soil management in combination with the needs of the local population is essential for a sustainable land use in the region.

Primär kutane B-Zell-Lymphome (PCBCL) beschreiben reifzellige lymphoproliferative Erkrankungen der B-Zell-Reihe, die primär die Haut betreffen. Die Biologie und der klinische Verlauf der einzelnen PCBCL-Subtypen variieren untereinander stark und unterscheiden sich grundsätzlich von primär nodalen und systemischen B-Zell-Lymphomen. Primär kutane Marginalzonenlymphome (PCMZL) und primäre kutane follikuläre Keimzentrumslymphome (PCFCL) werden auf Grund ihres unkomplizierten Verlaufs und ihrer exzellenten Prognose zu den indolenten PCBCL gezählt. Demgegenüber stellen die diffus großzelligen B-Zell-Lymphome, hauptsächlich vom Beintyp (DLBCL, LT) die aggressiveren PCBCL-Varianten mit schlechterer Prognose dar. Für die Ausbreitungsdiagnostik und die Therapieentscheidung sind eine genaue histologische und immunhistochemische Klassifizierung sowie der Ausschluss einer systemischen Beteiligung in Abgrenzung zu nodalen oder systemischen Lymphomen notwendig. Die Diagnostik sollte dabei durch molekularbiologische Untersuchungen unterstützt werden. Therapeutisch stehen für die indolenten PCBCL primär operative und radioonkologische Maßnahmen im Vordergrund sowie eine Systemtherapie mit dem CD20-Antikörper Rituximab bei disseminiertem Befall. Die aggressiveren Varianten sollten in erster Linie mit Kombinationen aus Rituximab und Polychemotherapieschemata wie z. B. dem CHOP-Schema oder Modifikationen davon behandelt werden. Auf Grund der in allen seinen Einzelheiten noch nicht vollständig verstandenen Pathogenese und Biologie sowie des begrenzten Therapiespektrums der PCBCL besteht hier, speziell beim DLBCL, LT, noch erheblicher Forschungsbedarf. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Purpose: This is an official guideline, published and coordinated by the Arbeitsgemeinschaft Gynäkologische Onkologie (AGO, Study Group for Gynecologic Oncology) of the Deutsche Krebsgesellschaft (DKG, German Cancer Society) and the Deutsche Gesellschaft für Gynäkologie und Geburtshilfe (DGGG, German Society for Gynecology and Obstetrics). The number of cases with vulvar cancer is on the rise, but because of the former rarity of this condition and the resulting lack of literature with a high level of evidence, in many areas knowledge of the optimal clinical management still lags behind what would be required. This updated guideline aims to disseminate the most recent recommendations, which are much clearer and more individualized, and is intended to create a basis for the assessment and improvement of quality care in hospitals. Methods: This S2k guideline was drafted by members of the AGO Committee on Vulvar and Vaginal Tumors; it was developed and formally completed in accordance with the structured consensus process of the Association of Scientific Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF). Recommendations: 1. The incidence of disease must be taken into consideration. 2. The diagnostic pathway, which is determined by the initial findings, must be followed. 3. The clinical and therapeutic management of vulvar cancer must be done on an individual basis and depends on the stage of disease. 4. The indications for sentinel lymph node biopsy must be evaluated very carefully. 5. Follow-up and treatment for recurrence must be adapted to the individual case. PMID:27765958

UV-induced skin cancer is not yet included in the German ordinance on occupational diseases and can only be notified and recognized acknowledged as "virtually-certain" occupational disease. The objective of the study was to analyze notified and acknowledged cases of occupational skin cancer due to UV-irradiation in Germany between 2005 and 2011. All notified cases of occupational skin cancer due to UV-irradiation have been analyzed which have been registered by the German Statutory accident insurance as of May 2012 were analyzed. The data analyze was descriptive stratified annually for presenting time trends.Data analysis was descriptive, stratified by year to defect time trends. Notified cases have increased annually with a total of 548 registered cases of occupational skin cancer induced by UV-irradiation between 2005 and 2011, and 74 recognized acknowledged cases. In 56 cases the procedure was not yet finished. Squamous cell carcinoma (SCC) and in-situ squamous cell carcinoma (actinic keratosis, Bowen's disease) were most frequent and have been the most frequentlyobserved in 333 notified cases. and between 15.6 % and 24.9 % have been recognizedof cases with SCC and actinic keratosis were recognized, respectively. 184 patients with basal cell carcinoma were notified but only 6.5 % recognized acknowledged and only 3 cases with exclusive basal cell carcinoma. Out of 50 notified patients with Mmelanoma only one was recognizedacknowledged. The results are in good agreement with the proposal of the German Minister of labor to establish UV-induced skin cancer as a new occupational disease. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

Anatomy in the Third Reich: Careers disrupted by National Socialist Policies.

Hildebrandt, Sabine

2012-06-01

The history of anatomy in the Third Reich is still insufficiently explored, especially concerning its victims. These include not only the victims of the NS regime whose bodies were used in anatomical dissection, but also the Scholars of Anatomy whose careers were disrupted by NS policies. The spectrum of career disruption spanned from short-term suspension from work to death in concentration camps. In this study, the biographies of 462 Scholars of Anatomy were examined. 414 were members of the Anatomische Gesellschaft (Anatomical Society). Eighty-six persons (80 men, 6 women) were identified whose anatomical careers were disrupted by National Socialist policies. Sixty-two of them were members of the Anatomical Society. Their subsequent fate was dependent on the stage of the scholars' careers, their field of expertise, reason for dismissal (i.e. so-called Jewish descent or political dissent), nationality, country of residence or exile. Forty-three scholars emigrated, of whom 6 returned to positions in Germany and Austria after the war. Twenty-one remained in their home countries, of whom 17 were later reinstated in their positions. Twelve scholars were imprisoned, and 5 died in concentration camps. Five fates remain unresolved. As diverse as this group of scholars was, all of them had in common that a criminal regime forced them, being innocent of any crime, out of their position and work. Further work including the exploration of potential archival sources is necessary before a detailed and complete recounting of each individual life is possible. Copyright © 2011 Elsevier GmbH.

Microbial degradation of petroleum was investigated in intact sediment cores of Caspian Sea during a simulated petroleum seepage using a sediment-oil-flow-through (SOFT) system. Over the course of the SOFT experiment (190 days), distinct redox zones established and evolved in the sediment core. Methanogenesis and sulfate reduction were identified to be important processes in the anaerobic degradation of hydrocarbons. C1 to C6 n-alkanes were completely exhausted in the sulfate-reducing zone and some higher alkanes decreased during the upward migration of petroleum. A diversity of sulfate-reducing bacteria was identified by 16s rRNA phylogenetic studies, some of which are associated with marine seeps and petroleum degradation. The δ13C signal of produced methane decreased from -33.7‰ to -49.5‰ indicating crude oil degradation by methanogenesis, which was supported by enrichment culturing of methanogens with petroleum hydrocarbons and presence of methanogenic archaea. The SOFT system is, to the best of our knowledge, the first system that simulates an oil-seep like condition and enables live monitoring of biogeochemical changes within a sediment core during petroleum seepage. During our presentation we will compare the Caspian Sea data with other sediments we studied using the SOFT system from sites such as Santa Barbara (Pacific Ocean), the North Alex Mud Volcano (Mediterranean Sea) and the Eckernfoerde Bay (Baltic Sea). This research was funded by the Deutsche Forschungsgemeinschaft (SPP 1319) and DEA Deutsche Erdoel AG. Further support came from the Helmholtz and Max Planck Gesellschaft.

Mast cell degranulation plays a momentous role in myriad diseases like asthma, eczema, allergic rhinitis, and conjunctivitis as well as anaphylactic shock; hence, there is an unmet need for developing new mast cells stabilizers. The reported mast cell stabilizers have a heterocyclic moiety and an acidic group. Furthermore, the role of tryptophan in suppression of mast cell activation is established. Hence, we prepared constrained analogs of tryptophan, which are derivatives of 2,3,4,9-tetrahydrospiro-β-carboline-3-carboxylic acid, and evaluated them for ex vivo inhibition of compound 48/80-induced mast degranulation activity. By comparing IC 50 (μM) values with that of the standard drug sodium cromoglycate (IC 50 = 0.489 ± 0.003 μM), compounds with bulky groups like heptyl (compound 9; IC 50 = 0.389 ± 0.015 μM) and octyl (compound 10; IC 50 = 0.354 ± 0.023 μM) were found to be of similar potency as sodium cromoglycate. Furthermore, the polar group-containing compounds like the chloropropyl (compound 16; IC 50 = 0.382 ± 0.083 μM) and benzoyl derivative (compound 14; IC 50 = 00.469 ± 0.032 μM) were also found to be of similar potency as sodium cromoglycate. This is a seminal study of spiro-β-carboline mast cell stabilization having a wider scope in mast cell research; yet, the mechanism of action remains elusive. © 2018 Deutsche Pharmazeutische Gesellschaft.

Seismic sounding of convection in the Sun

Thermal convection is the dominant mechanism of energy transport in the outer envelope of the Sun (one-third by radius). It drives global fluid circulations and magnetic fields observed on the solar surface. Convection excites a broadband spectrum of acoustic waves that propagate within the interior and set up modal resonances. These acoustic waves, also called seismic waves, are observed at the surface of the Sun by space- and ground-based telescopes. Seismic sounding, the study of these seismic waves to infer the internal properties of the Sun, constitutes helioseismology. Here we review our knowledge of solar convection, especially that obtained through seismic inference. Several characteristics of solar convection, such as differential rotation, anisotropic Reynolds stresses, the influence of rotation on convection and supergranulation, are considered. On larger scales, several inferences suggest that convective velocities are substantially smaller than those predicted by theory and simulations. This discrepancy challenges the models of internal differential rotation that rely on convective stresses as a driving mechanism and provide an important benchmark for numerical simulations.

17 adenovirus strains were found to be antigenically related to prototype Ad 15 by neutralization. No relationship to Ad 15, but to Ad 9 could be detected by hemagglutination-inhibition; we therefore named them Ad 15/H9 intermediate strains. After analysis of the genome by five different restriction enzymes, the fragment patterns obtained deviated widely from the prototype Ad 15, but only slightly from Ad 9. Differences could also be observed among the variants. After digestion by five restriction enzymes, altogether six genome types could be established among the 17 intermediate strains. To map the variations on the genome of the 15/H9 strains, two methods were employed: the double digestion of the DNA and DNA fragments together with the determination of the terminal fragments made it possible to construct a physical map. The second method depends on a particularity of adenoviruses: the DNA is covalently linked with a 55 kD protein at the 5' terminus. After digestion of the DNA, which does contain this protein, the terminal DNA fragments do not migrate into the agarose gel; after an additional digestion with pronase B, they do migrate into the gel. Thus the terminal fragments were determined by comparing the fragment patterns with and without previous pronase B treatment.

Nucleic acid amplification techniques (NATs), such as PCR, are highly sensitive and specific methods that have become valuable supplements to culture and serology in the diagnosis of infectious disorders. However, especially when using formalin-fixed and paraffin-embedded tissue, these techniques are associated with both false-negative and false-positive results, a pitfall that is frequently misjudged. Representatives of the German Society of Hygiene and Microbiology (DGHM) and the German Society of Dermatology (DDG) therefore set out to develop a consensus - in the form of a review article - on the appropriate indications for NATs using paraffin-embedded tissue, its contraindications, and the key points to be considered in the pre- and post-analytical phase. Given that fresh, naive tissue is preferably to be used in the workup of a suspected infection, PCR analysis on paraffin sections represents an exception. The latter may be considered if an infection is suspected at a later point in time and fresh tissue has not been preserved or can no longer be obtained. Potential indications include confirmation of histologically suspected infections with Leishmania spp., Bartonella spp., Rickettsia spp., or in case of ecthyma contagiosum. Infections with, for example, mycobacteria or RNA viruses, on the other hand, are not considered useful indications for NATs using paraffin sections. In order to avoid misinterpretation of test results, it is essential that laboratory reports on NATs using paraffin-embedded tissue contain information on the indication/diagnostic circumstances, the required and chosen pre-analytical steps, the limitations of the method, and on diagnostic alternatives. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

Pemphigus vulgaris (PV) wird in der Regel mit systemischen Corticosteroiden und Immunsuppressiva behandelt. Avaskuläre Nekrose (AVN) des Hüftkopfes ist eine gut bekannte schwerere Komplikation einer Corticosteroid-Therapie. Die Charakteristika dieser schweren Komplikation bei PV sind nach wie vor unbekannt. Nicht kontrollierte, retrospektive Untersuchung aller PV-bedingten AVN-Fälle, die in einer iranischen Klinik für bullöse Autoimmunerkrankungen zwischen 1985 und 2013 diagnostiziert wurden. Anhand der Krankenakten von 2321 untersuchten PV-Patienten wurden 45 Fälle (1,93 %) von femoraler AVN identifiziert. Dreißig davon waren Männer. Das mittlere Alter bei der Diagnose der AVN betrug 47,4 ± 14,2 Jahre. Der mittlere Zeitraum zwischen der Diagnose des PV und dem Einsetzen der AVN lag bei 25,3 ± 18,3 Monaten. Mit Ausnahme von acht Fällen (17,8 %) setzte die AVN bei der Mehrheit der Patienten innerhalb von drei Jahren nach Diagnose des PV ein. Die mittlere kumulative Dosis von Prednisolon bei Patienten mit AVN betrug 13.115,8 ± 7041,1 mg. Zwischen der Prednisolon-Gesamtdosis und dem Zeitraum bis zum Einsetzen der AVN bestand eine starke Korrelation (p = 0,001). Bei Patienten mit Alendronateinnahme in der Vorgeschichte war dieser Zeitraum signifikant kürzer (p = 0,01). Die AVN ist eine schwere Komplikation einer Corticosteroid-Behandlung bei Patienten mit PV. Sie wird bei 2 % der Patienten beobachtet und tritt vor allem in den ersten drei Behandlungsjahren auf. Bei Patienten, die höhere Dosen von Prednisolon erhalten, setzt die AVN tendenziell früher ein. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Eine Säule der kausalen Therapie bei Patienten mit Ulcus cruris venosum ist die Kompressionstherapie. Sie unterstützt die Abheilung, reduziert Schmerzen und Rezidive und steigert die Lebensqualität. Bislang existieren kaum wissenschaftliche Daten zu dem Versorgungsstand und fachspezifischem Wissen von Patienten mit Ulcus cruris venosum. Standardisierte Fragebögen wurden bundesweit in 55 Pflegediensten, 32 Arztpraxen, vier Wundzentren und -sprechstunden sowie einem Pflegetherapiestützpunkt von Patienten mit Ulcus cruris venosum bei Erstvorstellung anonym ausgefüllt. Insgesamt nahmen 177 Patienten (Durchschnittsalter 69,4 Jahre; 75,1 % Frauen) teil. Ein florides Ulcus cruris venosum bestand im Mittel 17 Monate. 31,1 % hatten keine Kompressionstherapie, 40,1 % Binden und 28,8 % Strümpfe. Bei der Bestrumpfung hatten 13,7 % Kompressionsklasse III, 64,7 % Kompressionsklasse II und 19,6 % Kompressionsklasse I. 70,6 % legten die Strümpfe nach dem Aufstehen an, 21,1 % trugen sie Tag und Nacht. 39,2 % bereiteten die Strümpfe Beschwerden. Lediglich 11,7 % hatten eine An- und Ausziehhilfe. Die Binden wurden im Mittel 40,7 Wochen getragen und bei 69 % nicht unterpolstert. Bei 2,8 % wurde der Knöchel- und Waden-Umfang zur Erfolgskontrolle gemessen. Venensport machten 45,9 %. Ein Drittel hatte keine Kompressionsversorgung, obwohl diese eine Basismaßnahme der Therapie des Ulcus cruris venosum ist. Zudem ist deren korrekte Auswahl und Anwendung angesichts der langen Bestandsdauer der Ulzerationen zu hinterfragen. Weiterführende Fachkenntnisse bei Anwendern und Verordnern sowie Patientenschulungen sind erforderlich. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Alitretinoin ist die einzige zugelassene Behandlung für schweres chronisches Handekzem (CHE), das refraktär gegenüber potenten topischen Corticosteroiden ist. Bei dieser Studie (FUGETTA) wurde die Wirksamkeit von leitliniengerecht angewendetem oralem Alitretinoin sowie dessen Einfluss auf die Lebensqualität (LQ) bei Patienten mit schwerem refraktärem CHE beurteilt. Multizentrische, offene, nichtinterventionelle Beobachtungsstudie, durchgeführt in Deutschland. Die Patienten wurden nach Ermessen ihres behandelnden Arztes mit Alitretinoin 10 mg oder 30 mg einmal täglich über maximal 24 Wochen behandelt. Die Wirksamkeit wurde anhand des Physician Global Assessment (PGA) und des Dermatology Life Quality Index (DLQI) bewertet. Zudem wurden unerwünschte Ereignisse (UE) erfasst. Die Studienpopulation bestand aus 658 Patienten (30 mg: n = 581; 10 mg: n = 77). Bei Beobachtungsbeginn litten die meisten Patienten (83 %) gemäß PGA an einem schweren CHE. Bei Beobachtungsende war das Handekzem bei 48 % der Patienten gemäß PGA vollständig oder fast vollständig abgeheilt (30 mg: 49 %; 10 mg: 43 %). Die mittlere Verbesserung des DLQI-Scores in Woche 24 betrug 58 % (30 mg: mittlere [SD] Veränderung gegenüber dem Ausgangswert -10,4 [8,04]) und 70 % (10 mg: mittlere [SD] Veränderung gegenüber dem Ausgangswert -10,8 [7,29]). Die Gesamtinzidenz von NW war niedrig und in den beiden Gruppen ähnlich.

Der übermäßige oder unkritische weltweite Einsatz von Antibiotika in der Medizin hat die Ausbreitung von Antibiotikaresistenzen beschleunigt. In einigen Bereichen sind viele Antibiotika bei bakteriellen Infektionen, die zuvor noch gut auf antibakterielle Wirkstoffe reagierten, mittlerweile wirkungslos geworden. Dermatologen/Venerologen setzten orale und topische Antibiotika bei der Behandlung von Acne vulgaris routinemäßig ein, obwohl Akne weder eine infektiöse Erkrankung ist noch alleine durch das Propionibacterium getriggert wird. Vielmehr ist sie eine komplexe, chronische entzündliche Hauterkrankung, die durch verschiedene pathogenetische Faktoren wie follikuläre Hyperkeratose, erhöhter Sebumproduktion, bakterielle Proliferation und Entzündung zustande kommt. Folglich sollte eine erfolgreiche Therapie auf die Bekämpfung verschiedener pathogenetischer Faktoren und nicht nur auf die von Propionibacterium acnes abzielen. Daher wurden topische Retinoide und Benzoylperoxid als Mittel der ersten Wahl definiert. Monotherapien mit lokalen Antibiotika sollten insgesamt vermieden werden. Systemische Antibiotika der Tetrazyklin-Gruppe haben bei bestimmen Krankheitsstadien ihren Sinn, ihre Wirkung könnte aber eher auf der antientzündlichen als auf der antibiotischen Reaktion beruhen. Gesundheitsbehörden ermahnen alle Gesundheitsdienstleister, den Einsatz von Antibiotika einzuschränken. Das Nutzen-Risiko-Verhältnis muss bei der Entscheidung für oder gegen eine antibiotische Therapie bei einem einzelnen Patienten immer auch in Bezug auf das öffentliche Interesse am Erhalt der Wirksamkeit von Antibiotika abgewogen werden. Im Folgenden werden das aktuelle Krankheitskonzept zu Acne vulgaris und die sich daraus ableitenden Konsequenzen für den Einsatz von Antibiotika vorgestellt. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Bei der (18) F-Fluordeoxyglucose-Positronenemissionstomographie/Computertomographie (FDG-PET/CT) ergeben sich häufig Zufallsbefunde. In der vorliegenden Studie konzentrierten wir uns auf mittels FDG-PET/CT erhaltene Zufallsbefunde bei Patienten mit kutanem Melanom und überprüften deren Relevanz hinsichtlich weiterer diagnostischer Maßnahmen und Interventionen. Die Krankenakten von 181 konsekutiven Melanom-Patienten wurden retrospektiv ausgewertet, um das Management von Zufallsbefunden zu dokumentieren. Der Schwerpunkt lag dabei auf den histologischen Befunden. Bei 33 von 181 (18 %) Patienten lagen 39 relevante Zufallsbefunde vor, und zwar im Kolorektalbereich (n = 15 Patienten), in der Schilddrüse (n = 8), der Prostata (n = 2), dem Bewegungsapparat (n = 2), in Lymphknoten (n = 2), der Parotis (n = 1), den Mandeln (n = 1), den Nieren (n = 1) und der Gallenblase (n = 1). Bei 25 Patienten schlossen sich weitere diagnostische Verfahren an, wobei in 21 Fällen ein klinisches Korrelat nachgewiesen wurde. Bei 16 von 21 Patienten ergab sich eine Neoplasie, darunter fünf maligne Läsionen (vier Kolonkarzinome und ein Prostatakarzinom). Die Malignome wurden frühzeitig diagnostiziert und in der Mehrzahl der Fälle erfolgreich entfernt. Der Einsatz der FDG-PET/CT als Routine-Diagnostik wird in den Leitlinien empfohlen und ist indiziert bei malignem Melanom ab Stadium IIC. In dieser Studie wurden auf effektive Weise ansonsten nicht erkannte Krebserkrankungen, insbesondere Kolonkarzinome, detektiert. In den meisten Fällen war eine frühe Intervention möglich. Zufallsbefunde durch FDG-PET/CT sollten, unter Berücksichtigung des Zustands und der Wünsche des Patienten, mit den geeigneten diagnostischen Maßnahmen abgeklärt werden. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Fetal electrocardiography is one of the methods for monitoring the well-being of the fetus. Signal loss limits the proper interpretation of electrocardiogram traces. The aim of this study was to assess the average signal loss in non-invasive abdominal fetal electrocardiogram (fECG) monitoring using the KOMPOREL fetal monitoring system (ITAM, Zabrze, Poland) in women between 28 and 42 week of pregnancy. The results were compared to FIGO (International Federation of Gynaecology and Obstetric) and DGGG (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe e.V.) recommendations concerning fetal heart monitoring. The correlation between fetal ECG signal quality, week of pregnancy and patient BMI was evaluated. 773 pregnant women, hospitalized and diagnosed in the Department of Gynecology and Obstetrics, Wroclaw Medical University, underwent 30 min of abdominal fECG recordings using the KOMPOREL fetal monitoring system. The average signal loss in abdominal fECG monitoring in the study group was 32%. FIGO recommendations describe an acceptable fetal signal loss of 20%. In our study, 46% (357/773) of the recordings were up to FIGO standards, with fetal heart rate success rates above 80%. According to DGGG guidelines, with acceptable fetal signal loss of 15%, only 39% (303/773) of the recordings could be assessed as accurate. No correlation between fECG signal quality, week of pregnancy and patient BMI was proved. The average signal loss in abdominal fECG monitoring in our study group was 32%. Low fECG signal quality may constitute a potentially limiting factor of the described fetal heart monitoring system. No relationship between fECG signal quality, week of pregnancy and patient BMI was proved.

Recent developments (new wavelengths, treatment concepts, and combinations) in the field of lasers, intense pulsed light (IPL), LED, as well as new energy and light sources have opened up new therapeutic options that extend beyond mere aesthetic indications. Thus, while fractional lasers used to be employed to merely treat wrinkles, the same devices - in the context of laser-assisted drug delivery - have now become important tools in the treatment of scars, field cancerization, and epithelial tumors. The requirements posed to physicians, both with respect to establishing the indication and conducting treatment, have been growing along with the increase in technological complexity as well as the rising number of comorbidities and comedications in a patient population that continues to age. At the same time, home-use devices have been introduced for a variety of indications. These devices are characterized by low power and special safety features aimed at preventing accidents, risks, and side effects. Despite the reduced efficacy of such self-treatment devices, there is an increased risk of misuse, given that the basic prerequisite for adequate treatment cannot be ensured, to wit, the exact diagnosis and therapeutic indication. Consequently, during hair removal or anti-wrinkle treatment, pigmented lesions and cutaneous neoplasms may be altered, thus giving rise to expected, unexpected and new side effects and complications. In the aforementioned setting, it is important that all potential users of these new technologies be properly trained in a manner that ensures those treated a maximum of safety and efficacy in accordance with the guiding principle "diagnosis certa - ullae therapiae fundamentum". © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Pflaum, Rainer; Egeler, Tobias

Die Übertragungsnetze stellen eine zuverlässige Versorgung von Haushalt, Gewerbe und Industrie mit elektrischer Energie sicher und sind damit Grundlage einer modernen Wirtschaft und Gesellschaft. Die mittlerweile unumkehrbaren Entwicklungen der nationalen und europäischen Energiewende stellen den Übertragungsnetzbetreiber in seinen Kernaufgaben, dem Bau und Betrieb von Netzen, dem Markt- und Netzzugang und der Integration der erneuerbaren Energien vor neue und große Herausforderungen. Verbrauchsnahe dezentrale Erzeugung wie verbrauchsferne zentrale Erzeugung muss im Sinne der Gewährleistung der Systemstabilität gemanagt und in Einklang mit dem Verbrauch gebracht werden. Erneuerbare Energien müssen zudem in einem solchen System ihren Beitrag zur System- und Marktintegration leisten. All das erfordert mehr Daten, um in einem Gesamtsystem dynamische Reaktionsmöglichkeiten gewährleisten zu können. Erst die "Digitalisierung" schafft dabei die notwendigen Voraussetzungen die Komplexität zu stemmen. Die Digitalisierung stellt daher ein Kernelement dieses Wandels des Übertragungsnetzbetreibers dar, die einerseits mit zum Entstehen der neuen Herausforderungen beiträgt, andererseits aber auch hilft Werkzeuge bereitzustellen, diesen Herausforderungen zu begegnen. Im folgenden Beitrag wird aufgezeigt, wie die Digitalisierung die Aufgaben und Instrumente des Übertragungsnetzbetreibers verändern. Ausgehend von den heutigen Aufgaben eines Übertragungsnetzbetreibers und dem gültigen Rechtsrahmen werden unter dem Begriff "Notwendiges Set für morgen" smarte Elemente und Werkzeuge beschrieben, die bereits heute im Einsatz sind oder in den nächsten Jahren notwendig werden. Im Anschluss erfolgt anhand einiger Beispiele aus unterschiedlichen Bereichen eine Konkretisierung der Einsatzzwecke der Digitalisierung beim Übertragungsnetzbetreiber. Ein kurzer Ausblick mit Fokus auf den weiteren Veränderungsprozess rundet den Beitrag ab.

Uncomplicated bacterial community-acquired urinary tract infection is among the more common infections in outpatient practice. The resistance level of pathogens has risen markedly. This S3 guideline contains recommendations based on current evidence for the rational use of anti - microbial agents and for the prevention of inappropriate use of certain classes of antibiotics and thus of the resulting drug resistance. The prevention of recurrent urinary tract infection is considered in this guideline for the first time. The guideline was updated under the aegis of the German Urological Society (Deutsche Gesellschaft für Urologie). A systematic literature search (period: 2008-2015) concerning the diagnosis, treatment, and prevention of uncomplicated urinary tract infections was carried out in the Cochrane Library, MEDLINE, and Embase databases. Randomized, controlled trials and systemic reviews were included. Relevant guidelines were identified in a guideline synopsis. Symptom-oriented diagnostic evaluation is highly valued. For the treatment of cystitis, fosfomycin-trometamol, nitrofurantoin, nitroxolin, pivmecillinam and trimethoprim are all equally recommended. Fluorquinolones and cephalosporins are not recommended. Uncomplicated pyelonephritis with a mild to moderate clinical course ought to be treated with oral cefpodoxime, ceftibuten, ciprofloxacin, or levofloxacin. For acute, uncomplicated cystitis, with mild to moderate symptoms, symptomatic treatment alone may be considered instead of antibiotics after discussion of the options with the patient. Mainly non-antibiotic measures are recommended for prophylaxis against recurrent urinary tract infection. Physicians who treat uncomplicated urinary tract infections should familiarize themselves with the newly revised guideline's recommendations on the selection and dosage of antibiotic treatment so that they can responsibly evaluate and plan antibiotic treatment for their affected patients.

Kutane Plattenepithelkarzinome (SCC) sind bekannt für ihre Fähigkeit, über Lymphgefäße zu metastasieren. In neueren Studien wird das Ausmaß der Lymphangiogenese als möglicher prognostischer Faktor bei einigen Hauttumoren genannt. Ziel dieser Studie war die Quantifizierung der Lymphangiogenese bei SCC entweder durch computergestützte Bildanalyse oder mithilfe der Zählmethode nach Chalkley. Gefäßparameter wurden im Hinblick auf ihre Vorhersagekraft für die Bildung von Tumormetastasen beurteilt und verglichen. In dieser Fallkontrollstudie wurden die klinischen und histologischen Daten von jeweils 15 SCC-Patienten mit bzw. ohne Metastasen retrospektiv analysiert. In den SCC-Proben wurde der für das Lymphendothel spezifische Marker D2-40 und der pan-vaskuläre Marker CD31 immunhistochemisch angefärbt und durch computergestützte morphometrische Bildanalyse in Hotspots sowie mithilfe der digitalisierten Zählmethode nach Chalkley analysiert. Die Dichte von Lymphgefäßen, die relative Lymphgefäßfläche und die mit der Chalkley-Methode ermittelte Zahl an Lymphgefäßen (Chalkley-Count) waren bei metastasierten SCC signifikant erhöht. Die Tumordicke war bei metastasierten SCC signifikant höher und besaß die höchste Vorhersagekraft für eine Metastasierung. Die Tumordicke war ein signifikanter Prädiktor für Lymphangiogeneseparameter. Die Lymphangiogenese ist bei metastasierten SCC erhöht, doch ihr Ausmaß wird von der Tumordicke beeinflusst. Die Tumordicke bildet weiterhin den zuverlässigsten prädiktiven Faktor für die Metastasierung. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Permanent magnet quadrupoles (PMQs) are an alternative to common electromagnetic quadrupoles especially for fixed rigidity beam transport scenarios at particle accelerators. Using those magnets for experimental setups can result in certain scenarios, in which a PMQ itself may be exposed to a large amount of primary and secondary particles with a broad energy spectrum, interacting with the magnetic material and affecting its magnetic properties. One specific scenario is proton microscopy, where a proton beam traverses an object and a collimator in which a part of the beam is scattered and deflected into PMQs used as part of a diagnostic system. During the commissioning of the PRIOR (Proton Microscope for Facility for Antiproton and Ion Research) high energy proton microscope facility prototype at Gesellschaft für Schwerionenforschung in 2014, a significant reduction of the image quality was observed which was partially attributed to the demagnetization of the used PMQ lenses and the corresponding decrease of the field quality. In order to study this phenomenon, Monte Carlo simulations were carried out and spare units manufactured from the same magnetic material—single wedges and a fully assembled PMQ module—were deliberately irradiated by a 3.6 GeV intense proton beam. The performed investigations have shown that in proton radiography applications the above described scattering may result in a high irradiation dose in the PMQ magnets. This did not only decrease the overall magnetic strength of the PMQs but also caused a significant degradation of the field quality of an assembled PMQ module by increasing the parasitic multipole field harmonics which effectively makes PMQs impractical for proton radiography applications or similar scenarios.

Since 15 years, the Alzheimer 's Telephone of the German Alzheimer Society (Deutsche Alzheimer Gesellschaft e.V.; DAlzG), a nationwide psychosocial counseling service, has been offering support for people with dementia (PwD) and their families. The aim of this study was to evaluate: a) why informal PwD caregivers seek telephone counseling, b) whether these telephone calls are one-time counseling or long-term support, and c) whether the telephone inquiries differ from the email-based inquiries with regard to the addressed issues. The data are based on the inquiries of 3,744 informal caregivers, which consulted the DAlzG in 2015. Sociodemographic data on the informal caregivers and the PwD, the characteristics of the telephone call, and the topics addressed in the email inquiries were collected. 70.3% of the callers were female. Most of them (59.9%) were the children (in-law) of and half of them (49.7%) lived with PwD. More than two-thirds of the callers (70%) were seeking help in dealing with the person with dementia (e. g. challenging behavior) and 36.5% of the relatives needed recommendations for further local help and assistance. In the third place, the calls were related to financial and legal topics (23.5%). 92.2% of the calls were one-time consultations. The addressed issues in the email inquiries did not significantly differ from the topics discussed over the telephone. On many topics there is a need for further "on site" consultation. Doctors and other health professionals should therefore be actively involved in counseling relatives of PwD. © Georg Thieme Verlag KG Stuttgart · New York.
German gynecologic societies investigating their Nazi past.

Research into the activities of German medical specialist associations during the Nazi period is still in its initial stages even today. In the field of gynecology and obstetrics as well, most representatives of the discipline continued to take an attitude based on "concealment and forgetting", even after the turn of the millennium. In order to break with this approach, the Bavarian Society for Obstetrics and Gynecology (Bayerische Gesellschaft für Geburtshilfe und Frauenheilkunde, BGGF) commissioned an interdisciplinary research group to focus on clarifying its Nazi past for the purposes of a history of the institution on the occasion of its centenary. The research was based on the Society's archive. When the files were found to show conspicuous gaps for the Nazi period, the investigation was extended into the role of BGGF representatives and members who were active at the time. In some cases, it was possible to draw on existing studies and to supplement the available information from additional archival sources. It was found that the BGGF started at a very early stage to marginalize and ignore its "non-Aryan" members. No official decision to exclude such members was apparently taken, however. Many representatives and honorary members of the society were involved in promoting and carrying out eugenic sterilizations, simultaneously conducting abortions on some victims, and they at least shared responsibility for forced abortions among Ostarbeiterinnen ("Eastern workers", forced laborers from Eastern Europe). Accompanying unethical research that was mainly intended to garner academic prestige for the physicians involved was never discussed at the Society's conferences. Representatives of the Society who were substantially incriminated were able to continue their careers almost without interruption after 1945.

Vernarbende Alopezien.

Primär vernarbende Alopezien (PVA) werden nach der Klassifikation der North American Hair Research Society nach ihrem prominenten entzündlichen Infiltrat in vier Gruppen eingeteilt: PVA mit lymphozytärem, neutrophilem, gemischtzelligem oder unspezifischem Entzündungsmuster. Der Haarausfall kann subklinisch beginnen und langsam fortschreiten, so dass der genaue Erkrankungsbeginn oft schwer nachzuvollziehen ist. Die Diagnose wird häufig verzögert gestellt. Während die meisten vernarbenden Alopezien bei vollständiger Ausprägung anhand des klinischen Bildes klar zugeordnet werden können, ist die Diagnosestellung in der Frühphase oder im Endstadium häufig schwierig. Bei Erstvorstellung sollte eine ausführliche Anamnese und dermatologische Ganzkörperuntersuchung, inklusive Trichoskopie durchgeführt werden. In klinisch unklaren Fällen sollte eine Biopsie erfolgen. Aufgrund der Seltenheit der PVA gibt es bisher nur eine niedrige Evidenz über die Wirksamkeiten der Vielzahl der verschiedenen angewandten Therapien. Ziele der Therapie einer PVA sind, den Haarausfall zu stoppen oder zumindest zu verzögern, die klinischen Entzündungszeichen zu reduzieren, weitere Vernarbung zu verhindern sowie die subjektiven Symptome zu lindern. Ein Nachwachsen in bereits vernarbten Arealen sollte nicht erwartet werden. Eine antientzündliche Therapie mit topischen Kortikosteroiden der Klasse III-IV und/oder mit intrakutanen intraläsionalen Triamcinolonacetonid-Injektionen kommt bei den meisten PVA in Betracht. Die Wahl der systemischen Therapie hängt von der Art des prädominierenden entzündlichen Infiltrates ab und umfasst antimikrobielle/antibiotische oder immunmodulatorische/immunsuppressive Ansätze. Psychologische Unterstützung und Camouflage-Techniken sollten den Patienten angeboten werden. © 2018 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

An international frequency comparison was carried out at the Bundesamt fuer Eich- und Vermessungswessen (BEV), Vienna, within the framework of the EUROMET Project #498 from August 29 to September 5, 1999. The frequency differences obtained when the RO.1 laser from the National Institute for Laser, Plasma and Radiation Physics (NILPRP), Romania, was compared with five lasers from Austria (BEV1), Czech Republic (PLD1), France (BIPM3), Poland (GUM1) and Hungary (OMH1) are reported. Frequency differences were computed by using the matrix determinations for the group d, e, f, g. Considering the frequency differences measured for a group of three lasers compared to each other, we call the closing frequency the difference between measured and expected frequency difference (resulting from the previous two measurements). For the RO1 laser, when the BIPM3 laser was the reference laser, the closing frequencies range from +8.1 kHz to - 3.8 kHz. The relative Allan standard deviation was used to express the frequency stability and resulted 3.8 parts in 1012 for 100 s sampling time and 14000 s duration of the measurements. The averaged offset frequency relative to the BIPM4 stationary laser was 5.6 kHz and the standard deviation was 9.9 kHz.
Numerical study of droplet impact and rebound on superhydrophobic surface

Droplet impact and rebound on superhydrophobic surface is an important process in many applications; among them are developing self-cleaning or anti-icing materials and limiting liquid film formation of Diesel Exhaust Fluid (DEF) in exhaust gas pipe. In the latter field, rebound of DEF droplet from wall is desired as an effective mean for avoiding or reducing unwanted solid deposition. Our goal is to numerically study influence of surface wettability on DEF droplet impact and rebound behavior. A phase-field method is chosen, which was implemented in OpenFOAM by us and validated for wetting-related interfacial flow problems. In the present contribution we first numerically reproduce relevant experimental studies in literature, to validate the code for droplet impact and rebound problem. There we study droplet-surface contact time, maximum/instantaneous spreading factor and droplet shape evolution. Our numerical results show good agreement with experimental data. Next we investigate for DEF droplets the effects of diameter, impact velocity and surface wettability on rebound behavior and jumping height. Based on Weber number and equilibrium contact angle, two regimes are identified. We show that surface wettability is a deciding factor for achieving rebound event.

Polymorphismen im ABCB1-Gen, das für das P-Glykoprotein kodiert, können die intrazelluläre Konzentration von Xenobiotika beeinflussen und so zur Entwicklung von Autoimmunerkrankungen, einschließlich des bullösen Pemphigoids (BP), beitragen. In der vorliegenden Studie sollte untersucht werden, ob in einer polnischen Kohorte die C3435T- und G2677T/A-Polymorphismen im ABCB1-Gen mit dem Risiko für ein BP assoziiert sind. Die Studie umfasste 71 Patienten mit BP und 156 gesunde Probanden. Der C3435T-Polymorphismus wurde mittels PCR-RFLP bestimmt und der G2677T/A-Polymorphismus mittels Allel-spezifischer PCR. Es gab zwar keine Korrelation zwischen dem C3435-Polymorphismus und dem BP-Risiko, aber wir konnten eine derartige Assoziation hinsichtlich des G2677T/A-Polymorphismus nachweisen. Das relative Risiko eines BP war bei Personen mit dem 2677TA-Genotyp um mehr als den Faktor fünf erhöht (OR = 5,52; p = 0,0063) und bei Trägern des 2677TT-Genotyps mehr als verdoppelt (OR = 2,40; p = 0,0076). Mit 2,40 (p = 0,000018) war die OR bei Trägern des 2677T-Allels ebenfalls erhöht. Die höhere Prävalenz des 2677GG-Genotyps und des 2677G-Allels bei der Kontrollgruppe sowie eine OR < 1,0 (0,22 beziehungsweise 0,33) legen eine Schutzfunktion des 2677G-Allels hinsichtlich der Ausbildung eines BP nahe. Die Ergebnisse der vorliegenden Studie zeigen, dass der G2677T/A-Polymorphismus im ABCB1-Gen das Risiko für die Entstehung eines BP beeinflussen könnte. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

Laut einer Befragung im Jahre 2012 war der Umgang mit Antithrombotika bei dermatochirurgischen Eingriffen in Deutschland sehr heterogen. 2014 wurde erstmals eine evidenzbasierte Leitlinie zu diesem Thema veröffentlicht. Es wurde eine anonyme Befragung derselben Stichprobe zum Umgang mit Antithrombotika sowie zu Kenntnissen der Leitlinie durchgeführt. Die Ergebnisse wurden als relative Häufigkeiten berichtet und denen aus 2012 gegenübergestellt. 208 Antwortbögen wurden ausgewertet (Rücklaufquote: 36,6 %). Die große Mehrheit der Dermatologen erklärte, kleinere Eingriffe unter Fortführung der Therapie mit Phenprocoumon, niedrig dosierter Acetylsalicylsäure (≤ 100 mg) und Clopidogrel sowie mit direkten oralen Antikoagulanzien durchzuführen. Bei größeren Eingriffen war der Umgang hingegen weiterhin heterogen, insbesondere unter niedergelassenen Dermatologen. Der Anteil der Dermatologen, die Phenprocoumon, Acetylsalicylsäure und Clopidogrel leitlinienkonform verwendeten, hat sich insgesamt vergrößert. Führten 2012 beispielsweise 53,8 % der Klinikärzte bzw. 36,3 % der niedergelassenen Dermatologen eine große Exzision unter Fortführung der Therapie mit niedrig dosierter Acetylsalicylsäure durch, taten dies 2017 90,2 % bzw. 57,8 % (Phenprocoumon: 33,8 % bzw. 11,9 % auf 63,9 % bzw. 29,9 %; Clopidogrel: 36,9 % bzw. 23,2 % auf 63,9 % bzw. 30,6 %). Unter den Klinikärzten war ein hoher Anteil mit der Leitlinie vertraut und fand diese hilfreich. Eine Zunahme des leitlinienkonformen Verhaltens war bei allen Eingriffen zu verzeichnen. Bei größeren Eingriffen zeigte sich trotz deutlicher Verbesserung die Notwendigkeit verstärkter Anstrengungen zur Leitlinienumsetzung bzw. zur Identifizierung von Implementierungsbarrieren. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

Die intraläsionale Gabe von Anti-CD20-Antikörpern (Rituximab) wurde als effektive Therapieoption für Patienten mit niedrig malignen primär kutanen B-Zell-Lymphomen beschrieben. Bis heute wurden allerdings keine Parameter identifiziert, welche reproduzierbar ein gutes klinisches Ansprechen dieser Therapie vorhersagen. Ziel dieser Studie ist, sowohl das klinische Ansprechen und die unerwünschten Nebenwirkungen als auch die Patientenwahrnehmung hinsichtlich intraläsionaler Injektionen von anti-CD20-Antikörpern zur Behandlung indolenter primär kutaner B-Zell-Lymphome im Vergleich mit anderen Therapien zu evaluieren. Elf Patienten mit einem primär kutanen B-Zell-Lymphom, namentlich primär kutanes Keimzentrumslymphom (n = 9) und primär kutanes Marginalzonenlymphom (n = 2), welche mittels intraläsionalem Anti-CD20-Antikörper behandelt wurden, wurden retrospektiv evaluiert hinsichtlich der Ansprechrate und unerwünschter Nebenwirkungen sowie in Bezug auf deren Selbsteinschätzung dieser und anderer Therapien des primär kutanen B-Zell-Lymphoms. Patienten, deren primär kutanes B-Zell-Lymphom mittels intraläsionaler Gabe von Anti-CD20-Antikörper behandelt wurde, zeigten ein komplettes oder partielles Ansprechen in 45 % beziehungsweise 27 % aller Patienten. Speziell Patienten mit grippeähnlichen Symptomen nach erfolgter Injektion zeigten ein gutes Ansprechen. Die Mehrheit der Patienten empfand die Therapie mit Rituximab als die beste Therapie im Vergleich zu anderen Therapien wie beispielsweise chirurgische Exzision oder Radiotherapie. Intraläsionales Rituximab ist eine effektive Therapie mit hoher Patientenzufriedenheit. Starke therapiebedingte Nebenwirkungen wie Fieber, Schüttelfrost und Kopfschmerzen nach Gabe von Rituximab könnten als Indikator für gute Wirksamkeit dienen. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

One of the main objectives of the experimental plasma physics activities at the Gesellschaft für Schwerionenforschung (GSI) are the interaction processes of heavy ions with dense ionized matter. Gas-discharge plasma targets were used for energy loss and charge state measurements in a regime of electron density and temperature up to 10 19 cm -3 and 20 eV, respectively. An improved model of the charge exchange processes in fully ionized hydrogen plasma, taking into account multiple excited electronic configurations which subsequently ionize, has removed the discrepancies of previous theoretical descriptions. The energy loss of the ion beam in partially ionized plasmas such as argon was found to agree very well with our simple theoretical model based on the modified Bethe-Bloch theory. A new setup with a 100 J/5 GW Nd-glass laser now provides access to density ranges up to 10 21 cm -3 and temperatures of up to 100 eV. First results of interaction experiments with laser-produced plasma are presented. To fully exploit the experimental possibilities of the new laser-plasma setup both improved charge state detection systems and better plasma diagnostics are indispensable. Present developments and future possibilities in these fields are presented. This paper summarizes the following contributions: Interaction of heavy-ion beams with laser plasma by C. Stöckl et al. Energy Loss of Heavy Ions in a laser-produced plasma by M. Roth et al. Charge state measurements of heavy ions passing a laser produced plasma with high time resolution by W. Süß et al. Plasma diagnostics for laser-produced plasma by O. Iwase et al. Future possibilities of plasma diagnostics at GSI by M. Geißel et al.

In 2009, the AJCC issued a revised melanoma staging system. In addition to tumor thickness and ulceration, the mitotic rate was introduced as the third major prognostic parameter for the classification of primary cutaneous melanoma. Given that, according to the 2009 AJCC classification, the detection of one or more dermal tumor mitoses leads to an upstaging - from stage Ia to Ib - of melanomas with a tumor thickness of ≤ 1.0 mm, we set out to investigate the reproducibility of this new parameter. In order to assess interobserver reliability, 17 dermatopathologists und pathologists - all well versed in the diagnosis of cutaneous melanoma - analyzed the mitotic rate in 15 thin primary cutaneous melanomas (mean tumor thickness 0.91 mm) using identical slides. Mitotic rates were determined on H&E and phosphohistone H3 (Ser10)-stained samples. Without knowledge of their previous assessment, five of the aforementioned examiners reevaluated the samples after more than one year in order to ascertain intraobserver reliability. Interobserver reliability of the mitotic rate in thin primary melanomas is disappointing and independent of whether H&E or immunohistochemically stained samples are used (kappa value: 0.088 [H&E], 0.154 [IH], respectively). Kappa values improved to 0.345 (H&E) and 0.403 (IH) when using a cutoff of 0/1 vs. 2+ mitoses. Similarly unsatisfactory, kappa values for intraobserver reliability ranged from 0.18 and 0.348, depending on the individual examiner. Given the unsatisfactory reproducibility and large variations in assessing the mitotic rate, it remains a matter of debate whether this diagnostic parameter should play a role in therapeutic decisions. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

A chronic wound is defined as an area where the skin is not intact that fails to heal within eight weeks. Such wounds usually develop on the lower limbs as a complication of diabetes, venous insufficiency, or inadequate arterial perfusion. Most of the roughly 45,000 limb amputations performed in Germany each year are necessitated by non-healing chronic wounds. In the development of this S3 guideline, a systematic search was performed that yielded 4998 references including 38 randomized, controlled trials and 26 systematic reviews, which were used as the basis for the recommendations and statements made in the guideline. Twelve member societies of the umbrella Association of Scientific Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF), as well as the German Association of Nursing Science (Deutsche Gesellschaft für Pflegewissenschaft, and patient representatives participated in the consensus rounds in which the guideline's recommendations and statements were agreed upon. This guideline contains seven evidence-based recommendations and 30 good clinical practice (GCP) recommendations. Evidence-based recommendations are given in favor of hydrogel, hyperbaric oxygenation, and integrated care, and against the use of medicinal honey and growth factors. Terms are defined precisely in order to ease communication and to specify what is meant by "wound debridement" (a procedure performed by a physician) as opposed to cleansing a wound. Under the premise of preventing pain, exudation, and maceration, local therapeutic agents can be chosen on the basis of the scientific evidence, the patient's preference, the physician's experience, and the wound situation. Costs should also be considered. Scant evidence is available to answer many of the relevant questions about chronic wounds. There are valid data in support of hyperbaric oxygen and integrated care. More research is needed.

While sport compression stockings (SCS) have become increasingly popular, there is no regulatory norm as exists for medical compression stockings (MCS). The objective of this pilot study was to compare five SCS with respect to their pressure profiles ex vivo and in vivo, and in relation to German standards for MCS (RAL norm). In vivo (10 competitive athletes; standardized procedure using the Kikuhime pressure monitor) and ex vivo (tested at the Hohenstein Institute) pressure profiles were tested for the following products: CEP Running Progressive Socks, Falke Running Energizing, Sigvaris Performance, X-Socks Speed Metal Energizer, and 2XU Compression Race Socks. Ex vivo ankle pressures of CEP (25.6 mmHg) and 2XU (23.2 mmHg) corresponded to class 2 MCS; that of Sigvaris (20.8 mmHg), to class 1 MCS. The remaining SCS achieved lower pressure values. The pressure gradients showed marked differences, and did not meet MCS standards. Average in vivo pressures were higher for 2XU, CEP, and Sigvaris than for Falke and X-Socks. However, in vivo values for all SCS were below those of class 1 MCS. None of the SCS showed the decreasing pressure gradient (from distal to proximal) required for MCS. In vivo and ex vivo pressure profiles of all SCS examined showed marked heterogeneity, and did not meet MCS standards. Consequently, the clinical and practical effects of SCS cannot be compared, either. It would therefore be desirable to establish a classification that allows for the categorization and comparison of various SCS as well as their selection based on individual preferences and needs (high vs. low pressure, progressive vs. degressive profile). © 2016 Deutsche Dermatologische Gesellschaft (DDG).

To analyze safety issues of regional anaesthesia and analgesia in Germany only a few single center studies are available. Therefore, the German Society for Anaesthesiology and Intensive Care Medicine (Deutschen Gesellschaft für Anästhesiologie und Intensivmedizin, DGAI) and the Professional Association of German Anaesthetists (Berufsverband Deutscher Anästhesisten, BDA) initiated a network for safety in regional anaesthesia. From this the first results on infectious complications will be reported. In a Delphi process the documentation of the setup and maintenance of regional anaesthesia and analgesia was agreed with the participants in a working group from the DGAI. After approval by the officially authorized representative for patient data privacy protection a registry was programmed to collect anonymous data. Up to October 2008 data from 6 centers could be analyzed. After testing for plausibility 8,781 regional anaesthesia procedures (22,112 catheter days) could be analyzed. The 5,057 neuraxial and 3,724 peripheral catheter-based procedures were in place for a median of 2.48 days (range 1.0-3.0 days) and 4 severe, 15 moderate and 128 mild infections were recorded. Diabetics were not found to show a statistically significant increase in risk (2.6% compared to 1.9% for non-diabetics: n.s.). Neuraxial procedures seem to have a higher rate of infections than peripheral procedures (2.7% vs. 1.3%, p<0.0001). Multiple punctures of the skin also seem to be associated with a higher infection rate than single skin punctures (4.1% vs. 1.6%, p<0.0001). Infectious complications of catheter-based regional anaesthesia are common. Strict hygienic standards must therefore be complied with. More data are necessary to calculate risk factors. The registry provided can also be used as a benchmark to reduce these rates further.

Lautstarker Applaus erhob sich im Salon III/IV des Marriott-Hotels von Crystal City im amerikanischen Bundesstaat Virginia. In dem überfüllten Konferenzraum starrten alle wie gebannt auf die Leinwand, wo nicht mehr zu sehen war als ein nüchternes Diagramm aus zahlreichen Punkten und einer geschwungenen Kurve. Nureine eigenartige Personengruppe konnte sich davon zu Emotionen hinreißen lassen - Physiker auf der Jahrestagung der Astronomischen Gesellschaft, die ihren Begeisterungssturm noch minutenlang fortsetzten. Was war geschehen? Die im Diagramm aufgetragenen Daten bestätigten mit einer nie da gewesenen Genauigkeit ein fundamentales Naturgesetz zur Wärmeabstrahlung von heißen Körpern. 1900 von Max Planck entdeckt, leuchtete es nun in geradezu mathematischer Reinheit auf. Noch sensationeller war der Ursprung der Daten - Mikrowellensignale verschiedener Frequenzen, die nicht aus einem irdischen Labor stammten, sondern von einem heißen Urzustand des Universums! Ein Feuerball aus Wasserstoff und Helium, noch ohne jegliche Strukturen, die irgendwann Leben ermöglichen sollten, ließ damals seinem Licht freien Lauf. Mehr als zehn Milliarden Jahre war es bis zu den Detektoren des vom Menschen gebauten Satelliten COBE unterwegs, der wenige Tage zuvor die Daten übertragen hatte. Wenn ich das alles wie einen Film in meiner Vorstellung ablaufen lasse, bekomme ich immer eine Gänsehaut, als würde ich die inzwischen extrem abgekühlte Strahlung tatsächlich spüren. Ihre Gleichverteilung im Raum macht uns auch deutlich, dass wir uns nicht einbilden dürfen, an einem besonderen Ort im Universum zu leben - intelligente Aliens könnten sich seitdem überall entwickelt haben! Sollten sie - was nicht wahrscheinlich ist - uns wirklich von Zeit zu Zeit über die Schulter schauen, dann hätten sie an jenem Nachmittag des 13.

The highly pathogenic avian influenza (HPAI) H5N1 outbreak at Qinghai Lake, China, in 2005 caused the death of over 6,000 migratory birds, half of which were Bar-headed Geese Anser indicus. Understanding the movements of this species may inform monitoring of outbreak risks for HPAI viruses; thus, we investigated the movement patterns of 29 Bar-headed Geese at Qinghai Lake, China during 2007 and 2008 by using high resolution GPS satellite telemetry. We described the movements and distribution of marked Bar-headed Geese during the pre-nesting, nesting, and moulting periods. Of 21 Bar-headed Geese with complete transmission records, 3 moved to other areas during the nesting period: 2 to Jianghe wetland (50 km northwest of Qinghai Lake) and 1 to Cuolongka Lake (220 km northwest of Qinghai Lake) during the nesting period. We identified nesting attempts of 7 of the marked geese at Qinghai Lake. Four completed successful nesting attempts according to our rules of judgment for the breeding status, and 2 geese lost broods soon after hatching (hereafter referred to as unsuccessful breeders). Of 18 geese present at Qinghai Lake during the nesting period, 9 (6 non-breeders, 2 successful breeders and 1 unsuccessful breeder) remained at Qinghai Lake during the moulting period; and 9 (5 non-breeders, 4 unsuccessful breeders) left Qinghai Lake for moulting. Kuhai Lake, Donggeicuona Lake, Alake Lake, Zhaling-Eling Lake area and Huangheyuan wetland area were used as moulting sites. Geese that moulted at Qinghai Lake, Cuolongka Lake, Kuhai Lake, Donggeicuona Lake and Alake Lake also moved to Zhaling-Eling Lake area or Huangheyuan wetland area and stayed there for several days prior to autumn migration. Mean home range and core area estimates did not differ significantly by sex, year and between breeders and non-breeders. ?? 2010 Dt. Ornithologen-Gesellschaft e.V.

Alzheimer's disease (AD), a neurodegenerative disorder, is a serious medical issue worldwide with drastic social consequences. Inhibition of cholinesterase is one of the rational and effective approaches to retard the symptoms of AD and, hence, consistent efforts are being made to develop efficient anti-cholinesterase agents. In pursuit of this, a series of 19 acetamide derivatives of chromen-2-ones were synthesized and evaluated for their acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory potential. All the synthesized compounds exhibited significant anti-AChE and anti-BChE activity, with IC 50 values in the range of 0.24-10.19 μM and 0.64-30.08 μM, respectively, using donepezil hydrochloride as the standard. Out of 19 compounds screened, 3 compounds, viz. 22, 40, and 43, caused 50% inhibition of AChE at 0.24, 0.25, and 0.25 μM, respectively. A kinetic study revealed them to be mixed-type inhibitors, binding with both the CAS and PAS sites of AChE. The above-selected compounds were found to be effective inhibitors of AChE-induced and self-mediated Aβ 1-42 aggregation. ADMET predictions demonstrated that these compounds may possess suitable blood-brain barrier (BBB) permeability. Hemolytic assay results revealed that these compounds did not lyse human RBCs up to a thousand times of their IC 50 value. MTT assays performed for the shortlisted compounds showed them to be negligibly toxic after 24 h of treatment with the SH-SY5Y neuroblastoma cells. These results provide insights for further optimization of the scaffolds for designing the next generation of compounds as lead cholinesterase inhibitors. © 2017 Deutsche Pharmazeutische Gesellschaft.

Die meisten früheren Arbeiten zu den klinisch-epidemiologischen Merkmalen von bullösen Autoimmunerkrankungen (AIBD) konzentrierten sich vor allem auf eine einzige Krankheitsentität oder nur eine Krankheitsgruppe; nur in wenigen Studien wurde die Inzidenz verschiedener AIBD untersucht. Bei der vorliegenden Studie war es unser Ziel, das gesamte Spektrum der AIBD zu betrachten, die Inzidenz der häufigsten AIBD zu ermitteln und die zeitlichen Trends ihres Auftretens in Zentralserbien über einen Zeitraum von 20 Jahren zu untersuchen. Wir rekrutierten retrospektiv 1161 AIBD-Fälle, die in Zentralserbien von Januar 1991 bis Dezember 2010 neu diagnostiziert wurden. Die Diagnose stützte sich auf eine strikte klinische, histologische und immunhistologische Beurteilung. Folgende Inzidenzraten wurden für die einzelnen Erkrankungen ermittelt: 4,35 pro eine Million Einwohner/Jahr (pME/Jahr) für Pemphigus, 4,47 pME/Jahr für Pemphigoid, 1,42 pME/Jahr für Dermatitis herpetiformis (DH), 0,25 pME/Jahr IgA-Dermatose und 0,08 pME/Jahr für Epidermolysis bullosa acquisita. Im betrachteten Zeitraum stieg die altersbereinigte Inzidenzrate für Pemphigus und insbesondere für Pemphigoid signifikant an, während sie für DH, allerdings nicht signifikant, abnahm. Unsere Studie befasst sich zum ersten Mal mit den Inzidenzraten des gesamten Spektrums der AIBD in Serbien und untersucht die zeitlichen Trends ihres Auftretens über einen Zeitraum von 20 Jahren. Nach unserem besten Wissen wurde ein ähnlicher Befund wie der unsere, dass nämlich die Inzidenzraten von Pemphigus und Pemphigoid vergleichbar sind, bisher noch nicht publiziert. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Simon Marius vs. Galileo: Who First Saw Moons of Jupiter?

Pasachoff, Jay M.; Van Helden, Albert

In his almanac for 1612 and book Mundus Iovalis of 1614, Simon Marius in Germany reported his discovery of moons around Jupiter, which he started writing down in late 1609 in the Julian calendar, which translated to 8 January 1610 in the Gregorian calendar in use by Galileo in Italy. Is Marius to be believed? Galileo certainly did not. But a Dutch jury of experts about three hundred years later reported that they validated the claim that Marius independently discovered the moons of Jupiter one day after Galileo first both saw and wrote down his discovery! There is no doubt that the names Io, Europa, Ganymede, and Callisto came from Marius (to whom they were suggested by Kepler). See JMP's Journal for the History of Astronomy article, 46(2), 218-234 (2015).Marius wrote that he had been observing the moons around Jupiter since November 1609 (Julian), using a neighboring nobleman's telescope, which would mean that he actually saw the Jupiter satellites first (though publish or perish). Whether this feat was technically possible comes down to discussions of the capabilities of telescopes in the early 17th century.The quadricentennial of Marius's book was celebrated in Nuremberg with a symposium that is now in press in German with an English translation expected. One of us (AVH) has recently prepared a complete English translation of Marius's book, superseding the partial translation made 100 years ago. There is no evidence that, whether he saw what we now call the Galilean satellites first or not, Marius appreciated their cosmological significance the way that Galileo soon did. And Marius was certainly the first to publish tables of the moons of Jupiter.We thank the Chapin Library of Williams College and the Huntington Library for assistance with first editions of Marius's 1614 book, and we thank Pierre Leich of the Simon Marius Gesellschaft for his consultations.

Non-steroidal anti-inflammatory drugs (NSAIDs), which are widely used for the treatment of rheumatic arthritis, pain, and many different types of inflammatory disorders, cause serious gastrointestinal (GI) side effects. The free carboxylic acid group existing on their chemical structure is correlated with GI toxicity related with all routine NSAIDs. Replacing this functional group with the 1,3,4-oxadiazole bioisostere is a generally used strategy to obtain an anti-inflammatory agent devoid of GI side effects. In the present work, a novel group of 5-(3,4-dichlorophenyl)-1,3,4-oxadiazole-2(3H)-one Mannich bases were synthesized and characterized on the basis of IR, 1 H NMR, and elemental analysis results. The target compounds were first tested for cytotoxicity to determine a non-toxic concentration for anti-inflammatory screening. Anti-inflammatory effects of the compounds were evaluated by in vitro lipopolysaccharide (LPS)-induced NO production and in vivo carrageenan footpad edema with ulcerogenic profile. In LPS-induced RAW 264.7 macrophages, most of the compounds showed inhibitory activity on nitrite production while compounds 5a, 5h, and 5j exhibited the best profiles by suppressing the NO production. To evaluate the in vivo anti-inflammatory potency of the compounds, the inflammatory response was quantified by increment in paw size in the carrageenan footpad edema assay. The anti-inflammatory data scoring showed that compounds 5a-d, 5g, and 5j, at the dose of 100 mg/kg, exhibited anti-inflammatory activity, which for compound 5g was comparable to that of the reference drug indomethacin with 53.9% and 55.5% inhibition in 60 and 120 min, respectively. © 2017 Deutsche Pharmazeutische Gesellschaft.

The Drau Glacier was the largest Pleistocene glacier in the southeastern part of the Alps and significantly shaped the landscape in this region. The study area is located at the termination of the Drau Glacier in the southern part of Austria (Carinthia). The investigation aims to decipher glacial dynamics during the Late Pleistocene glacial advance, stabilisation and final recession of this glacier based on geological/geomorphological mapping, interpretation of airborne laser scan (ALS) topographic data and lithostratigraphic investigations of glacial and periglacial sediments. Special emphasis is laid on the reconstruction of the maximum extent of the glaciation (LGM). Based on previous mapping by Bobek (1959) and Ucik (1996-1998) more details have been gained for the paleogeographic reconstruction based on glacial and non-glacial erosion and accumulation features. These include traces of pre-Upper Pleistocene glaciation, drumlins, terminal moraines and kettle holes. Paleogeographic reconstruction was done with correlation of different outcrops based on lithostratigraphy and ALS topography. Sequences of gravel related to glacial advance covered by till, followed by periglacial sediments allowed detailed reconstruction of the glacial sequence in this area and the complex succession of various extents of the Drau Glacier.

One of the reasons for young doctors to leave the clinical work to go abroad or into non-clinical fields is insufficient quality of training under bad circumstances. Aim of the study was to evaluate the surgical training in Germany from the viewpoint of the residents. A questionnaire was prepared by residents and consultants and approved by the German surgical societies (Deutsche Gesellschaft fur Chirurgie und Berufsverband der Deutschen Chirurgen). It was sent to surgical residents between June 2003 and June 2004, published in "Der Chirurg BDC" and distributed among residents taking part in courses conducted by the BDC. It could be answered anonymously by email, mail or online. The questionnaire was sent back by 584 surgical residents (about 30 % of all). 58 % of the residents declared that they finished the training in the intended time (6 years). Rotation-systems as part of a structured residency program existed for 43 %. Standard surgical procedures were discussed or explained before the procedure in only 46 %. 61 % of the residents were not satisfied with the teaching assistance by their clinical teachers in the OR. Only 33 % had regular talks with the Chief about their progress in surgical training. 18 % of residents felt, that the hospital is interested in their progress in training. Indication-conferences took place in 52 % and mortality-conferences in only 20 % of programs. Regular seminars on recent issues took place in 62 %, and 61 % of residents did not get financial support to attend congresses. 36 % of residents had to use their holidays to attend congresses. Surgical training structures are not well established in about 50 % of the training hospitals from where we got answers to our survey. The training potential of daily surgical work is not used appropriately. It is therefore imperative to develop guidelines for surgical training, the use of log-books and rotation-programs.

Extemporaneous formulations broaden the spectrum of therapeutic options for topical treatment in particular and thus improve patient care. The latest amendment to the Regulation on the Operation of Pharmacies issued in 2012 brought about changes in prescribing and manufacturing practices. The aim of the present study was to assess the relevance of extemporaneous formulations in everyday clinical practice. We used data from the German Institute for Drug Use Evaluation (DAPI) to analyze the prescribing practice for compounded preparations in Germany between the fourth quarter of 2011 and the third quarter of 2014. In doing so, we determined the total cost associated with extemporaneous formulations covered by statutory health insurance funds in the outpatient setting. Approximately three out of ten prescriptions (30.54 %) by German dermatologists during the observation period were extemporaneous formulations. While dermatologists make up only 2.7 % of physicians working in the statutory health care system in Germany, they prescribe more than half of all compounded preparations (53.6 %). Each dermatologist prescribed an average of 270.4 formulations per quarter; that number was 13.5 (1.3 %) for all other medical specialties. On average, 1,983,687 extemporaneous formulations overall (1.3 % of all prescriptions) were prescribed per quarter, corresponding to a total cost of € 40,944,982 (0.55 %). Apart from finished medicinal products, extemporaneous formulations play a key role in outpatient care. Based on the principles of evidence-based and patient-oriented medicine, the quality of compounded preparations and the prescribing practice of physicians (standardized vs. individual formulations) should be further investigated to optimize the quality of these preparations. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

Though scientifically undisputed, cutaneous syncarcinogenesis is not reflected in German occupational disease (OD) regulations, which tend to be guided by the tenet of monocausality. Recognition of nonmelanoma skin cancer (NMSC) and its precursor lesions as OD requires individual assessment as to whether the requirements pursuant to either OD 5103 (occupational exposure to natural UV radiation) or OD 5102 (occupational exposure to polycyclic aromatic hydrocarbons) are fulfilled. Retrospective analysis of 28 patients (median age 72.5 years) with NMSC and respective precursor lesions who had been occupationally exposed to natural UV radiation and polycyclic aromatic hydrocarbons. All cases had undergone expert medical assessment between September 2012 and September 2015. According to our assessments, all 28 cases met the occupational requirements pursuant to OD 5103 and 5102. In 26 cases (93 %), we recommended recognition of skin cancer as occupational disease pursuant to both OD 5103 and OD 5102. The competent occupational insurance association (BG) followed our recommendation in four cases. In eight cases, recognition was solely based on OD 5103; in ten cases, only on OD 5102. Four cases were denied recognition. Following adequate cumulative occupational exposure to natural UV light as well as occupational exposure to polycyclic aromatic hydrocarbons, NMSC or its precursor lesions arising in UV-exposed areas should be reported to the competent occupational insurance association as "OD 5103 and 5102 in terms of syncarcinogenesis". Apart from the fact that the ensuing recognition proceedings will be able to more adequately reflect real-life workplace conditions, filing a report pursuant to both ODs also allows for recognition of basal cell carcinoma as occupational disease. According to current regulations, this would not be possible, if the assessment were solely based on OD 5103. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons

The static and dynamic behavior of measuring systems determine the value indicated by the measuring systems in relation to the true operating conditions. This paper demonstrates the necessity to involve the behavior of measuring systems in accident analysis with the thermohydraulic code ATHLET (developed by GRS Germany) by the example of hydrostatic water level measurement for horizontal steam generators on NPP (VVER). The modelling of a comparison vessel for the level measuring system with high sensitivity and a limited range of measurement (narrow-range level measuring system) by using ATHLET components and the checking of the function of the module weremore » realized. A good correspondence (maximal deviation 3%) between the measured and calculated narrow-range water level by the module was obtained for a realized post calculation of a measured operational transient in a NPP (VVER). The research carried out was sponsored by the Federal Ministry for Research and Technology within the projects {open_quotes}Basic research of process and system behaviour of NPP, control technique for accident management{close_quotes} (Project number 150 0855/7) and the project RS 978.

The Seventeenth International Microgravity Measurements Group (MGMG) meeting was held 24-26 March 1998 at the Ohio Aerospace Institute (OAI) in Brook Park, Ohio. This meeting focused on the transition of microgravity science research from the Shuttle, Mir, and free flyers to the International Space Station. The MGMG series of meetings are conducted by the Principal Investigator Microgravity Services project of the Microgravity Science Division at the NASA Lewis Research Center. The MGMG meetings provide a forum for the exchange of information and ideas about the microgravity environment and microgravity acceleration research in the Microgravity Research Program. The meeting had participation from investigators in all areas of microgravity research. The attendees included representatives from: NASA centers; National Space Development Agency of Japan; European Space Agency; Daimler Benz Aerospace AG; Deutsches Zentrum fuer Luft- und Raumfahrt; Centre National d'Etudes Spatiales; Canadian Space Agency, national research institutions; Universities in U.S., Italy, Germany, and Russia; and commercial companies in the U.S. and Russia. Several agencies presented summaries of the measurement, analysis, and characterization of the microgravity environment of the Shuttle, Mir, and sounding rockets over the past fifteen years. This extensive effort has laid a foundation for pursuing a similar course during future microgravity science experiment operations on the ISS. Future activities of microgravity environment characterization were discussed by several agencies who plan to operate on the ISS.

The high flux solar furnace that is operated by the Deutsche Forschungsanstalt fuer Luft- und Raumfahrt (DLR) at Cologne was inaugurated in June 1994 and we are now able to look back onto one year of successful operation. The solar furnace project was founded by the government of the State Northrhine Westfalia within the Study Group AG Solar. The optical design is a two-stage off-axis configuration which uses a flat 52 m{sup 2} heliostat and a concentrator composed of 147 spherical mirror facets. The heliostat redirects the solar light onto the concentrator which focuses the beam out of the opticalmore » axis of the system into the laboratory building. At high insolation levels (>800W/m{sup 2}) it is possible to collect a total power of 20 kW with peak flux densities of 4 MW/m{sup 2}. Sixteen different experiment campaigns were carried out during this first year of operation. The main research fields for these experiments were material science, component development and solar chemistry. The furnace also has its own research program leading to develop sophisticated measurement techniques like remote infrared temperature sensing and flux mapping. Another future goal to be realized within the next five years is the improvement of the performance of the furnace itself. 6 refs., 9 figs., 1 tab.« less

Filaments play a central role in the molecular clouds' evolution, but their internal dynamical properties remain poorly characterized. To further explore the physical state of these structures, we have investigated the kinematic properties of the Musca cloud. We have sampled the main axis of this filamentary cloud in 13CO and C18O (2-1) lines using APEX observations. The different line profiles in Musca shows that this cloud presents a continuous and quiescent velocity field along its ~6.5 pc of length. With an internal gas kinematics dominated by thermal motions (I.e. σNT/cs ≲ 1) and large-scale velocity gradients, these results reveal Musca as the longest velocity-coherent, sonic-like object identified so far in the interstellar medium. The transonic properties of Musca present a clear departure from the predicted supersonic velocity dispersions expected in the Larson's velocity dispersion-size relationship, and constitute the first observational evidence of a filament fully decoupled from the turbulent regime over multi-parsec scales. This publication is based on data acquired with the Atacama Pathfinder Experiment (APEX).

An interferometer is composed of several radio telescopes (dishes) separated by a defined distance and used in synchrony. This kind of array produces a superior angular resolution, better than the resolution achieved by a single dish of the same combined area. In this work we propose the First Educational Youth Mexican Array North South, FEYMANS. It consists of an educational interferometer with initially four dishes. This array harvests Mexico's geography by locating each dish at the periphery of the country; creating new scientific links of provincial populations with the capital. The FEYMANS project focus in high school students and their projects on physics, chemistry and astronomy as a final project. Also, it can be used for bachelor theses. The initial and central dish-node is planed to be in Mexico City. After its construction, the efforts will focus to build subsequent nodes, on the Northwest region, Northeast, or Southeast. Region Northwest will give service to Baja California, Sonora and Chihuahua states. Region Northeast will cover Coahuila, Nuevo Leon and Tamaulipas. Finally, region Southeast will give access to Yucatan, Quintana Roo, Campeche, Tabasco and Chiapas. This project has been conceived by young professional astronomers and Mexican experts that will operate each node. Also, we have the technical support of the "Max Planck Institute fuer Radioastronomy in Bonn Germany" and the educational model of the "PARTNeR" project in Spain. This interferometer will be financed by Mexico's Federal Congress and by Mexico City's Legislative Assembly (ALDF).
Measurements of Gas-phase H2so4, Oh, So2 and Aerosol Size Distribution On Mount Zugspitze At The Schneefernerhaus: Estimation of Sources and Sinks of Sulfuric Acid

Gas-phase sulfuric acid and OH have been measured by the novel MPI-K ULTRA- CIMS (ultra-trace gas detection by CIMS technique) at the Schneefernerhaus( 2750 m asl; below the summit of Mount Zugspitze, Germany) in October 2001. These mea- surements were accompanied by measurements of SO2 with another MPI-K CIMS instrument and aerosol size distribution measurements by DMPS (differential mobil- ity particle sizer) operated by the Institut fuer Wasserchemie (Technische Universitaet Muenchen). In that way a data set was obtained which allows investigating major sources and sinks of sulfuric acid under relative clean conditions. H2SO4 and espe- cially OH concentrations are relatively well correlated to solar flux. Noon maximum concentrations of OH and H2SO4 of 6.5·106 and 2·106 cm-3, respectively, were ob- served. The average SO2 concentrations were below 20 ppt. The aerosol size distribu- tion was obtained in 39 size ranges from 10 to 1056 nm. Typical aerosol concentrations are in the range of 400 to 1800 cm-3 during the discussed period of time. An estima- tion of the production rate of H2SO4 was inferred building on the reaction of SO2 and OH, while the loss rate was calculated by considering the condensation of H2SO4 on aerosol particles (Fuchs and Sutugin approach). Results of the measurements and calculations will be discussed.

The Stratospheric Observatory For Infrared Astronomy (SOFIA) is an international cooperative development and operations program between the United States National Aeronautics and Space Administration (NASA) and the German Space Agency, DLR (Deutsches Zentrum fuer Luft-und Raumfahrt). SOFIA is a 2.5 meter, optical/infrared/sub-millimeter telescope mounted in a Boeing model 747SP-21 aircraft and will be used for many basic astronomical observations performed at stratospheric altitudes. It will accommodate installation of different focal plane instruments with in-flight accessibility provided by investigators selected from the international science community. The Facility operational lifetime is planned to be greater than 20 years. This presentation will present the results of developmental testing of SOFIA, including analysis, envelope expansion and the first operational mission. It will describe a brief history of open cavities in flight, how NASA designed and tested SOFIAs cavity, as well as flight test results. It will focus on how the test team achieved key milestones by systematically and efficiently reducing the number of test points to only those absolutely necessary to achieve mission requirements, thereby meeting all requirements and saving the potential loss of program funding. Finally, it will showcase examples of the observatory in action and the first operational mission of the observatory, illustrating the usefulness of the system to the international scientific community. Lessons learned on how to whittle a mountain of test points into a manageable sum will be presented at the conclusion.

Background Data on the incidence of in-flight medical emergencies on-board civil aircraft are uncommon and rarely published. Such data could provide information regarding required medical equipment on-board aircraft and requisite training for cabin crew. The aim of the present study was to gather data on the incidences, nature, and medical equipment for in-flight medical emergencies by way of a survey of physician members of a German aerospace medical society. Materials and methods Using unipark.de (QuestBack GmbH, Cologne, Germany), an online survey was developed and used to gather specific information. Members of the German Society for Aviation and Space Medicine (Deutsche Gesellschaft für Luft- und Raumfahrtmedizin e.V.; DGLRM) were invited to participate in the survey during a 4-week period (21 March 2015 to 20 April 2015). Chi-square test was used for statistical analysis (p<0.05 was considered significant). Results Altogether, 121 members of the society responded to the survey (n=335 sent out). Of the 121 respondents, n=54 (44.6%) of the participants (89.9% male and 10.1% female; mean age, 54.1 years; n=121) were involved in at least one in-flight medical emergency. Demographic parameters in this survey were in concordance with the society members’ demographics. The mean duration of flights was 5.7 hours and the respondents performed 7.1 airline flights per year (median). Cardiovascular (40.0%) and neurological disorders (17.8%) were the most frequent diagnoses. The medical equipment (78.7%) provided was sufficient. An emergency diversion was undertaken in 10.6% of the cases. Although using a different method of data acquisition, this survey confirms previous data on the nature of emergencies and gives plausible numbers. Conclusion Our data strongly argue for the establishment of a standardized database for recording the incidence and nature of in-flight medical emergencies. Such a database could inform on required medical equipment and cabin crew training

Background and research question: The hospital sector is currently characterized by a high economic pressure. As well the DRG system as the investment financing by the federal states imply financial limitations. Hospitals react to this situation by trying to reduce costs and to increase case volume. It is questionable whether and to what extent patient care and the working conditions of the physicians are affected by these circumstances. Especially, gastroenterological patients were considered to be insufficiently covered by the DRG system in the past. Therefore, this study focuses on the gastroenterology. Method: Based on prior studies and several semi-structured interviews with gastroenterologists working in hospitals a discipline-specific questionnaire was developed. Three versions of the questionnaire were differentiated to correspond to the respective experiences of the target population (chief physician, senior physician, assistant physician). All in all, 1751 members of the "Deutsche Gesellschaft für Gastroenterologie, Verdauungs- und Stoffwechselkrankheiten" (DGVS) were addressed. The questionnaire was answered by 642 participants resulting in a response rate of 36.7 %. The answers were interpreted by using descriptive and multivariate analyses. Results: A significant economic pressure is perceived by the participating gastroenterologists. This pressure manifests itself primary in perceived deficits in nursing care and human attention towards the patients. Moreover, the work satisfaction is negatively affected. Identified difficulties in the personnel recruitment can only be partially attributed to economic reasons. However, rationing of services is relatively seldom. Also, a financially-oriented overprovision is not perceived as a primary concern. In general, assistant physicians were a bit more skeptical about the situation in the gastroenterology, e. g. patient care, than the chief physicians. Conclusions: In total, the situation in the

Astronomers wanting to chart the whole sky or even part of it 24/7 must collaborate across nations, continents, and hemispheres. The Greeks were perhaps the first to try, but the pioneering modern international scientific project, von Zach’s “Himmelspolitzei,” started in 1800 at Schröter’s Lilienthal Observatory, only to have the city burned and the observatory looted by retreating French soldiers in 1813. The first post-Vereinigte Astronomische Gesellschaft asteroid wasn’t found until 1845. A few international efforts were completed in the 19th century (the AGKI and BD); the Paris-centered Carte du Ciel (1887-1964) might have been done faster with American participation (cf. the League of Nations and the international treaty that declared, without the US, the moon to be the “common Heritage of Mankind”). Kapteyn’s Selected Areas (1906) and Hale’s Solar Union (1907) were just getting started. And then there was a war, ending with a treaty (Versailles) that abolished all previously-existing cultural and scientific organizations and called for new ones, to include only the victorious countries. This included the IAU. Neutrals were to come later and the losers maybe never. In fact, partly for financial reasons, Germany did not join until 1948. Nationalistic issues have slowly disappeared from IAU agendas since the “two adhering organizations” solution was adopted for China in 1982. Member countries now come and go, mostly for economic reasons. So where are we in this International Year of Light? Discouraged by ever-brightening night skies, with bright cities signifying vibrant economies and contrails extending across borders and oceans. But also with SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) due to start up in 2015; things run late, so perhaps in the upcoming centenary of the death of Solar Union member Karl Schvarzschild.

Aims: We aim to validate the Einstein equivalence principle (local position invariance) by limiting the fractional changes in the electron-to-proton mass ratio, μ = me/mp, measured in Galactic plane objects. Methods: High-resolution spectral observations of dark clouds in the inversion line of NH3(1, 1) and pure rotational lines of other molecules (the so-called ammonia method) were performed at the Medicina 32-m and the Effelsberg 100-m radio telescopes to measure the radial velocity offsets, ΔRV = Vrot - Vinv, between the rotational and inversion transitions, which have different sensitivities to the value of μ. Results: In our previous observations (2008-2010), a mean offset of ⟨ΔRV⟩ = 0.027 ± 0.010 km s-1 (3σ confidence level (C.L.)) was measured. To test for possible hidden errors, we carried out additional observations of a sample of molecular cores in 2010-2013. As a result, a systematic error with an amplitude ~0.02 km s-1 in the radial velocities was revealed. The averaged offset between the radial velocities of the rotational transitions of HC3N(2-1), HC5N(9-8), HC7N(16-15), HC7N(21-20), and HC7N(23-22), and the inversion transition of NH3(1, 1) is ⟨ΔRV⟩ = 0.003 ± 0.018 km s-1 (3σ C.L.). This value, when interpreted in terms of Δμ/μ = (μobs - μlab)/μlab, constraints the μ-variation at the level of Δμ/μ < 2 × 10-8 (3σ C.L.), which is the most stringent limit on the fractional changes in μ based on astronomical observations. Based on observations obtained with the Effelsberg 100-m telescope operated by the Max-Planck Institut für Radioastronomie on behalf of the Max-Planck-Gesellschaft (Germany), and with the Medicina 32-m telescope operated by INAF (Italy).

In 2007, the German national guidelines on "Treatment of acute perioperative and post-traumatic pain" were published. The aim of this study was to describe current structure and process data for acute pain management in German hospitals and to compare how the guidelines and other initiatives such as benchmarking or certification changed the healthcare landscape in the last decade. All directors of German departments of anesthesiology according to the DGAI ("Deutschen Gesellschaft für Anästhesiologie und Intensivmedizin", German Society for Anesthesiology and Intensive Care) were mailed a standardized questionnaire on structures and processes of acute pain management in their hospitals. A total of 403 completed questionnaires (46 %) could be evaluated. Of hospitals, 81 % had an acute pain service (ASD), whereby only 45 % met defined quality criteria. Written standards for acute pain management were available in 97 % of the hospitals on surgical wards and 51 % on nonsurgical wards. In 96 %, perioperative pain was regularly recorded (generally pain at rest and/or movement, pain-related functional impairment in 16 % only). Beside these routine measurements, only 38 % of hospitals monitored pain for effectiveness after acute medications. Often interdisciplinary working groups and/or pain managers are established for hospital-wide control. As specific therapy, the patient-controlled analgesia and epidural analgesia are largely prevalent (> 90 % of all hospitals). In the last decade, intravenous and oral opioid administration of opioids (including slow release preparations) has become established in acute pain management. The survey was representative by evaluating 20 % of all German hospitals. The organizational requirements for appropriate pain management recommended by the German guidelines for acute pain recommended have been established in the hospital sector in recent years. However, the organizational enforcement for acute pain management in

The image on the right is a false-color composite version combining violet, green and infrared images to enhance color differences in the predominantly water-ice crust of Europa. Dark brown areas represent rocky material derived from the interior, implanted by impact, or from a combination of interior and exterior sources. Bright plains in the polar areas (top and bottom) are shown in tones of blue to distinguish possibly coarse-grained ice (dark blue) from fine-grained ice (light blue). Long, dark lines are fractures in the crust, some of which are more than 3,000 kilometers (1,850 miles) long. The bright feature containing a central dark spot in the lower third of the image is a young impact crater some 50 kilometers (31 miles) in diameter. This crater has been provisionally named "Pwyll" for the Celtic god of the underworld. Europa is about 3,160 kilometers (1,950 miles) in diameter, or about the size of Earth's moon. This image was taken on September 7, 1996, at a range of 677,000 kilometers (417,900 miles) by the solid state imaging television camera onboard the Galileo spacecraft during its second orbit around Jupiter. The image was processed by Deutsche Forschungsanstalt fuer Luftund Raumfahrt e.V., Berlin, Germany. http://photojournal.jpl.nasa.gov/catalog/PIA00502
Investigations and results concerning railway-induced ground-borne vibrations in Germany

Besides noise reduction, ground-borne vibrations induced by railways are another important environmental issue associated with the construction of new or the reconstruction of existing railway lines that had to be tackled during the last decade. Annoyance can occur, particularly for lines in urban areas at small distances to neighbouring houses or lines in shallow depth tunnels under buildings. The ground-borne vibrations can be perceived by the inhabitants via the floor vibrations, as well as via the air-borne noise radiated inside the building by the vibrating building structures (secondary noise). At present, legal specifications for judging railway-induced ground-borne vibrations do not exist in Germany. In order to review common practices, an experimental psycho-physical laboratory study was performed. To estimate the annoyance of railway-induced vibrations, the mean vibration energy of a train pass-by seems much more significant and related to the annoyance than the commonly used RMS value according to the German standard DIN 4150-2. The minimum difference in vibration that can be felt by people was found at a signal difference of 25%. This paper will review results of a project performed in cooperation with the engineering office Obermeyer in Munich and the Technical University of Munich [A. Said, D. Fleischer, H. Kilcher, H. Fastl, H.-P. Grütz, Zur Bewertung von Erschütterungsimmissionen aus dem Schienenverkehr, Zeitschrift fuer Lärmbekämpfung, Vol. 48(6), Springer VDI Verlag, Düsseldorf, 2001.] and will link them to further demands on research and on development of suitable guiding principles and legislative regulations.
Highly miniaturized FEEP propulsion system (NanoFEEP) for attitude and orbit control of CubeSats

NASA Astrophysics Data System (ADS)

Bock, Daniel; Tajmar, Martin

2018-03-01

A highly miniaturized Field Emission Electric Propulsion (FEEP) system is currently under development at TU Dresden, called NanoFEEP [1]. The highly miniaturized thruster heads are very compact and have a volume of less than 3 cm3 and a weight of less than 6 g each. One thruster is able to generate continuous thrust of up to 8 μN with short term peaks of up to 22 μN. The very compact design and low power consumption (heating power demand between 50 and 150 mW) are achieved by using Gallium as metal propellant with its low melting point of approximately 30 °C. This makes it possible to implement an electric propulsion system consisting of four thruster heads, two neutralizers and the necessary electronics on a 1U CubeSat with its strong limitation in space, weight and available power. Even formation flying of 1U CubeSats using an electric propulsion system is possible with this system, which is shown by the example of a currently planned cooperation project between Wuerzburg University, Zentrum fuer Telematik and TU Dresden. It is planned to use the NanoFEEP electric propulsion system on the UWE (University Wuerzburg Experimental) 1U CubeSat platform [2] to demonstrate orbit and two axis attitude control with our electric propulsion system NanoFEEP. We present the latest performance characteristics of the NanoFEEP thrusters and the highly miniaturized electronics. Additionally, the concept and the current status of a novel cold neutralizer chip using Carbon Nano Tubes (CNTs) is presented.

The Visible Tunable Filter (VTF) is a narrowband tunable filter system for imaging spectroscopy and spectropolarimetry based. The instrument will be one of the first-light instruments of the Daniel K. Inouye Solar Telescope that is currently under construction on Maui (Hawaii). The VTF is being developed by the Kiepenheuer Institut fuer Sonnenphysik in Freiburg as a German contribution to the DKIST. We perform end-to-end simulations of spectropolarimetric observations with the VTF to verify the science requirements of the instrument. The instrument is simulated with two Etalons, and with a single Etalon. The clear aperture of the Etalons is 250 mm, corresponding to a field of view with a diameter of 60 arcsec in the sky (42,000 km on the Sun). To model the large-scale figure errors we employ low-order Zernike polynomials (power and spherical aberration) with amplitudes of 2.5 nm RMS. We use an ideal polarization modulator with equal modulation coefficients of 3-1/2 for the polarization modulation We synthesize Stokes profiles of two iron lines (630.15 nm and 630.25 nm) and for the 854.2 nm line of calcium, for a range of magnetic field values and for several inclination angles. We estimated the photon noise on the basis of the DKIST and VTF transmission values, the atmospheric transmission and the spectral flux from the Sun. For the Fe 630.25 nm line, we obtain a sensitivity of 20 G for the longitudinal component and for 150 G for the transverse component, in agreement with the science requirements for the VTF.

Biomes computed from simulated climatologies

The biome model of Prentice et al. is used to predict global patterns of potential natural plant formations, or biomes, from climatologies simulated by ECHAM, a model used for climate simulations at the Max-Planck-Institut fuer Meteorologie. This study undertaken in order to show the advantage of this biome model in diagnosing the performance of a climate model and assessing effects of past and future climate changes predicted by a climate model. Good overall agreement is found between global patterns of biomes computed from observed and simulated data of present climate. But there are also major discrepancies indicated by a differencemore » in biomes in Australia, in the Kalahari Desert, and in the Middle West of North America. These discrepancies can be traced back to in simulated rainfall as well as summer or winter temperatures. Global patterns of biomes computed from an ice age simulation reveal that North America, Europe, and Siberia should have been covered largely by tundra and taiga, whereas only small differences are for the tropical rain forests. A potential northeast shift of biomes is expected from a simulation with enhanced CO{sub 2} concentration according to the IPCC Scenario A. Little change is seen in the tropical rain forest and the Sahara. Since the biome model used is not capable of predicting chances in vegetation patterns due to a rapid climate change, the latter simulation to be taken as a prediction of chances in conditions favourable for the existence of certain biomes, not as a reduction of a future distribution of biomes. 15 refs., 8 figs., 2 tabs.« less

Professor H Winter. It was with great sadness that we learnt of the death of colleague and friend Professor Hannspeter Winter in Vienna on the 8 November 2006. In memory of him and the contribution he made both to our conference and to the field of the physics of highly charged ions we dedicate these proceedings. Hannspeter was one of our distinguished invited speakers at HCI2006 and gave a talk on the status of the ITER programme. His invited paper on the subject is included in these proceedings. Hannspeter will be particularly remembered for his pioneering work on ion-surface interactions that, together with his colleagues at the Vienna University of Technology (TUW), has stimulated a worldwide experimental and theoretical interest in this field. He was appointed Director of the Institut fuer Allgemeine Physik at TUW in 1987 and using both his scientific and management skills has made it one of the leading university physics laboratories in the world. His research publications, of which there are 270, have inspired many others to work in the field of atomic and plasma physics. He was also a great European playing a major role in the EURATOM fusion programme, the European Physical Society and the International Union of Pure and Applied Physics and was an evaluator and advisory board member for many national and international institutions. Hannspeter was also an interesting and friendly social companion with interests in current affairs, music and fine wines and will be greatly missed both on a scientific and social level. Our condolences go to his wife Renate, son Dorian and his relatives. R W McCullough Co-chair HCI2006
Performance Simulations for a Spaceborne Methane Lidar Mission

Future spaceborne lidar measurements of key anthropogenic greenhouse gases are expected to close current observational gaps particularly over remote, polar, and aerosol-contaminated regions, where actual in situ and passive remote sensing observation techniques have difficulties. For methane, a "Methane Remote Lidar Mission" was proposed by Deutsches Zentrum fuer Luft- und Raumfahrt and Centre National d'Etudes Spatiales in the frame of a German-French climate monitoring initiative. Simulations assess the performance of this mission with the help of Moderate Resolution Imaging Spectroradiometer and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations of the earth's surface albedo and atmospheric optical depth. These are key environmental parameters for integrated path differential absorption lidar which uses the surface backscatter to measure the total atmospheric methane column. Results showthat a lidar with an average optical power of 0.45W at 1.6 µm wavelength and a telescope diameter of 0.55 m, installed on a low Earth orbit platform(506 km), will measure methane columns at precisions of 1.2%, 1.7%, and 2.1% over land, water, and snow or ice surfaces, respectively, for monthly aggregated measurement samples within areas of 50 × 50 km2. Globally, the mean precision for the simulated year 2007 is 1.6%, with a standard deviation of 0.7%. At high latitudes, a lower reflectance due to snow and ice is compensated by denser measurements, owing to the orbital pattern. Over key methane source regions such as densely populated areas, boreal and tropical wetlands, or permafrost, our simulations show that the measurement precision will be between 1 and 2%.
DIY EOS: Experimentally Validated Equations of State for Planetary Fluids to GPa Pressures, Tools for Understanding Planetary Processes and Habitability

Sound speeds are fundamental to seismology, and provide a path allowing the accurate determination of thermodynamic potentials. Prior equations of state (EOS) for pure ammonia (Harr and Gallagher 1978, Tillner-Roth et al. 1993) are based primarily on measured densities and heat capacities. Sound speeds, not included in the fitting, are poorly predicted.We couple recent high pressure sound speed data with prior densities and heat capacities to generate a new equation of state. Our representation fits both the earlier lower pressure work as well as measured sound speeds to 4 GPa and 700 K and the Hugoniot to 70 GPa and 6000 K.In contrast to the damped polynomial representation previously used, our equation of state is based on local basis functions in the form of tensor b-splines. Regularization allows the thermodynamic surface to be continued into regimes poorly sampled by experiments. We discuss application of this framework for aqueous equations of state validated by experimental measurements. Preliminary equations of state have been prepared applying the local basis function methodology to aqueous NH3, Mg2SO4, NaCl, and Na2SO4. We describe its use for developing new equations of state, and provide some applications of the new thermodynamic data to the interior structures of gas giant planets and ocean worlds.References:L.

10 years after the first introduction of a digital airborne mapping camera in the ISPRS conference 2000 in Amsterdam, several digital cameras are now available. They are well established in the market and have replaced the analogue camera. A general improvement in image quality accompanied the digital camera development. The signal-to-noise ratio and the dynamic range are significantly better than with the analogue cameras. In addition, digital cameras can be spectrally and radiometrically calibrated. The use of these cameras required a rethinking in many places though. New data products were introduced. In the recent years, some activities took place that should lead to a better understanding of the cameras and the data produced by these cameras. Several projects, like the projects of the German Society for Photogrammetry, Remote Sensing and Geoinformation (DGPF) or EuroSDR (European Spatial Data Research), were conducted to test and compare the performance of the different cameras. In this paper the current DIN (Deutsches Institut fuer Normung - German Institute for Standardization) standards will be presented. These include the standard for digital cameras, the standard for ortho rectification, the standard for classification, and the standard for pan-sharpening. In addition, standards for the derivation of elevation models, the use of Radar / SAR, and image quality are in preparation. The OGC has indicated its interest in participating that development. The OGC has already published specifications in the field of photogrammetry and remote sensing. One goal of joint future work could be to merge these formerly independent developments and the joint development of a suite of implementation specifications for photogrammetry and remote sensing.

From 2011 to 2014, the BESIII experiment collected about 5 fb-1 data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states. By analyzing the di-muon process e+e- → γISR/FSRμ+μ-, the center-of-mass energies of the data samples are measured with a precision of 0.8 MeV. The center-of-mass energy is found to be stable for most of the time during data taking.

Non-communicable disease is a leading threat to global health. Physical inactivity is a large contributor to this problem; in fact, the WHO ranks it as the fourth leading risk factor for overall morbidity and mortality worldwide. In Canada, at least 4 of 5 adults do not meet the Canadian Physical Activity Guidelines of 150 min of moderate-to-vigorous physical activity per week. Physicians play an important role in the dissemination of physical activity (PA) recommendations to a broad segment of the population, as over 80% of Canadians visit their doctors every year and prefer to get health information directly from them. Unfortunately, most physicians do not regularly assess or prescribe PA as part of routine care, and even when discussed, few provide specific recommendations. PA prescription has the potential to be an important therapeutic agent for all ages in primary, secondary and tertiary prevention of chronic disease. Sport and exercise medicine (SEM) physicians are particularly well suited for this role and should collaborate with their primary care colleagues for optimal patient care. The purpose of this Canadian Academy and Sport and Exercise Medicine position statement is to provide an evidence-based, best practices summary to better equip SEM and primary care physicians to prescribe PA and exercise, specifically for the prevention and management of non-communicable disease. This will be achieved by addressing common questions and perceived barriers in the field.Author note This position statement has been endorsed by the following nine sport medicine societies: Australasian College of Sports and Exercise Physicians (ACSEP), American Medical Society for Sports Medicine (AMSSM), British Association of Sports and Exercise Medicine (BASEM), European College of Sport & Exercise Physicians (ECOSEP), Norsk forening for idrettsmedisin og fysisk aktivite (NIMF), South African Sports Medicine Association (SASMA), Schweizerische Gesellschaft für Sportmedizin

Gynaecological cancer centres have been established nationwide in Germany since 2008 according to the certification system of the German Cancer Society (Deutsche Krebsgesellschaft e. V. [DKG]) and the German Society for Gynaecology and Obstetrics (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe e. V. [DGGG]). However, patient access to the certified gynaecological cancer centres is currently only possible through direct referrals. A longitudinal structure with the corresponding long-term documentation of both the high-grade precursors as well as the cancers does not exist as yet. According to the aims of the National Cancer Plan, a corresponding structure for the cancer entity “cervix carcinoma” should be established. The foundations for such a structure are appropriate diagnostic units that are responsible, after nationwide screening, for clarification according to guideline-conform principles. On the basis of the vote of the certification commission for gynaecological cancer centres under the chairmanship of the DKG, the Working Group for Gynaecological Oncology (Arbeitsgemeinschaft Gynäkologische Onkologie e. V. [AGO]), the Committee on Cervical Pathology and Colposcopy (Arbeitsgemeinschaft Zervixpathologie & Kolposkopie [AG-CPC]) and the DGGG the certification system for gynaecological dysplasia has been established. As a general principle, a distinction is made between the certification of a consulting practice for gynaecological dysplasia and a gynaecological dysplasia facility in order to integrate both outpatient and inpatient health-care facilities into the certification system. In analogy to the further catalogue of requirements from the DKG, quantitative and qualitative minimum numbers are demanded. Furthermore, the requirements of the certification process include a summary of patient information, the applied guidelines, continuing and further training, interdisciplinary cooperation in tumour boards, contents or, respectively

The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA), the mass spectrometer suite on board the European Space Agency's Rosetta mission, was dedicated to the measurement of the volatiles in the coma of comet 67P/Churyumov-Gerasimenko (67P) [1]. Among many other species, ROSINA DFMS, the Double Focusing Mass Spectrometer, detected and quantified the three noble gases argon, krypton, and xenon including their major isotopes [2,3]. Noble gases provide important clues to the physical and chemical conditions during and possibly even before and after the comet's formation in the early solar system. Furthermore, measurements of the isotope ratios provide constraints on the amount of cometary material brought to Earth and its early atmosphere. In this presentation, we will report on the measured coma densities and derived nucleus bulk abundances of these three noble gases and investigate correlations with other volatiles. Furthermore, we will discuss the measured isotope ratios and the implications of these results.

The purpose of this survey was to determine how commonly, and in what clinical situations, German-based orthodontists use skeletal anchorage devices in daily clinical practice. In early 2013, a set of questionnaires on the subject of skeletal anchorage devices was mailed to 2459 members of the German Orthodontic Society (Deutsche Gesellschaft für Kieferorthopädie, DGKFO). The questions dealt separately with mini screws (MSCs) and osseointegrated palatal implants (OPIs). The addresses were asked whether or not, as well as how frequently and in what clinical situations, they used these MSCs and/or OPIs, what their experience was, and to elaborate on their reasons for using or not using these devices. The rate of returned questionnaires was 48 %. To correctly interpret our data, it should be kept in mind that an unknown number of respondents did not distinguish between OPIs and palatally inserted MSCs. Overall, 62 % indicated that they did use MSCs and/or OPIs, although most of them (> 50 %) infrequently (≤ 2 new patients/3 months). Only ≤ 2 % were frequent users (> 2 new patients/week). While most users (> 70 %) indicated that their experience was mostly good, only ≤ 50 % considered the devices easy and trouble-free to use in daily clinical practice. The median percentage of insertion procedures conducted by the respondents themselves was 2 % for MSCs and 0 % for OPIs. Many of the non-users indicated that their treatment concept did not include suitable clinical indications (≥ 50 %), expressed skepticism about the success rates (56 % of MSC and 21 % of OPI non-users), or thought that the insertion procedures involved were too complex or time-consuming (33 % of MSC and 56 % of OPI non-users). A total of 62 % of German-based orthodontists participating in this survey indicated using skeletal anchorage devices, although most of them infrequently. Major reasons for non-use were lack of clinical indications, skepticism

A large list of common proper motion stars selected from the third Astronomischen Gesellschaft Katalog (AGK3) was monitored with the CORAVEL (for COrrelation RAdial VELocities) spectrovelocimeter, in order to prepare a sample of physical binaries with very wide separations. In paper I,66 stars received special attention, since their radial velocities (RV) seemed to be variable. These stars were monitored over several years in order to derive the elements of their spectroscopic orbits. In addition, 10 of them received accurate RV measurements from the SOPHIE spectrograph of the T193 telescope at the Observatory of Haute-Provence. For deriving the orbital elements of double-lined spectroscopic binaries (SB2s), a new method was applied, which assumed that the RV of blended measurements are linear combinations of the RV of the components. 13 SB2 orbits were thus calculated. The orbital elements were eventually obtained for 52 spectroscopic binaries (SBs), two of them making a triple system. 40 SBs received their first orbit and the orbital elements were improved for 10 others. In addition, 11 SBs were discovered with very long periods for which the orbital parameters were not found. It appeared that HD 153252 has a close companion, which is a candidate brown dwarf with a minimum mass of 50 Jupiter masses. In paper II, 80 wide binaries (WBs) were detected, and 39 optical pairs were identified. Adding CPM stars with separations close enough to be almost certain they are physical, a "bias-controlled" sample of 116 wide binaries was obtained, and used to derive the distribution of separations from 100 to 30,000 au. The distribution obtained doesn't match the log-constant distribution, but is in agreement with the log-normal distribution. The spectroscopic binaries detected among the WB components were used to derive statistical informations about the multiple systems. The close binaries in WBs seem to be similar to those detected in other field stars. As for the WBs, they
Wilhelm Winkler (1842-1910) - a Thuringian private astronomer and maecenas

NASA Astrophysics Data System (ADS)

Weise, Wilfried; Dorschner, Johann; Schielicke, Reinhardt E.

Wilhelm Winkler was born in 1842 in Eisenberg, Thuringia, as the son of a lawyer. After attending the trading high school in Gera, Winkler worked as a merchant in Eisenberg, following in the footsteps of his grandfather. In 1875 he gave up this trade and devoted his time entirely to astronomy. Advised by Carl Bruhns, director of the Leipzig University Observatory, he established an observatory on his estate in Gohlis near Leipzig. From 1878 Winkler regularly observed sunspots; other fields of his observational interests were comets, occultations of stars by the Moon, and Jupiter's satellites. In 1887 he went to Jena, where he contacted Ernst Abbe, who was the head of the Jena observatory, too. For some years, Winkler's instruments were used in the new observatory erected by Abbe, which replaced the old Ducal Observatory of the Goethe era. Winkler donated the precision pendulum clock and some other instruments to this observatory. He also offered his observational assistance whenever it was wanted. In 1893 Winkler built up his own observatory in Jena and published annual reports on his work in the Vierteljahrsschrift of the Astronomische Gesellschaft. His observational results mainly appeared in the journal Astronomische Nachrichten. In 1902 he was awarded an honorary doctor's degree by the Philosophical Faculty of Jena University. However, at that time his physical constitution began gradually to fade. He lost his left eye due to a sarcoma, and finally he died at the age of 68. In his will, he left 100 000 Mark in form of securities to Jena University (Winkler Foundation). The University Observatory got his 4.5 m dome, the transport of which from his residence to the final site was also paid for by him, several instruments, and a lot of books. In 1936 Winkler's dome was closed by the University. The observatory was transferred from the University to the Zeiss works in exchange for the observatory in the Jena Forst. Zeiss sponsored the reconstruction of the old dome

Due to the implementation of the diagnosis-related groups (DRG) system, the competitive pressure on German hospitals increased. In this context it has been shown that acute pain management offers economic benefits for hospitals. The aim of this study was to analyze the impact of the competitive situation, the ownership and the economic resources required on structures and processes for acute pain management. A standardized questionnaire on structures and processes of acute pain management was mailed to the 885 directors of German departments of anesthesiology listed as members of the German Society of Anesthesiology and Intensive Care Medicine (DGAI, Deutsche Gesellschaft für Anästhesiologie und Intensivmedizin). For most hospitals a strong regional competition existed; however, this parameter affected neither the implementation of structures nor the recommended treatment processes for pain therapy. In contrast, a clear preference for hospitals in private ownership to use the benchmarking tool QUIPS (quality improvement in postoperative pain therapy) was found. These hospitals also presented information on coping with the management of pain in the corporate clinic mission statement more often and published information about the quality of acute pain management in the quality reports more frequently. No differences were found between hospitals with different forms of ownership in the implementation of acute pain services, quality circles, expert standard pain management and the implementation of recommended processes. Hospitals with a higher case mix index (CMI) had a certified acute pain management more often. The corporate mission statement of these hospitals also contained information on how to cope with pain, presentation of the quality of pain management in the quality report, implementation of quality circles and the implementation of the expert standard pain management more frequently. There were no differences in the frequency of using the benchmarking

Thermal-Hydraulic-Mechanical (THM) Coupled Simulation of a Generic Site for Disposal of High Level Nuclear Waste in Claystone in Germany: Exemplary Proof of the Integrity of the Geological Barrier

NASA Astrophysics Data System (ADS)

Massmann, J.; Ziefle, G.; Jobmann, M.

Claystone is investigated as a potential host rock for the disposal of high level nuclear waste (HLW). In Germany, DBE TECHNOLOGY GmbH, the BGR and the "Gesellschaft für Anlagen- und Reaktorsicherheit (GRS)" are developing an integrated methodology for safety assessment within the R&D project "ANSICHT". One part herein is the demonstration of integrity of the geological barrier to ensure safe containment of radionuclides over 1 million years. The mechanical excavation of an underground repository, the exposition of claystone to atmospheric air, the insertion of backfill, buffer, sealing and supporting material as well as the deposition of heat producing waste constitute a significant disturbance of the underground system. A complex interacting scheme of thermal, hydraulic and mechanical (THM) processes can be expected. In this work, the finite element software OpenGeoSys, mainly developed at the "Helmholtz Centre for Environmental Research GmbH (UFZ)", is used to simulate and evaluate several THM coupled effects in the repository surroundings up to the surface over a time span of 1 million years. The numerical setup is based on two generic geological models inspired by the representative geology of potentially suitable regions in North- and South Germany. The results give an insight into the evolution of temperature, pore pressure, stresses as well as deformation and enables statements concerning the extent of the significantly influenced area. One important effect among others is the temperature driven change in the densities of the solid and liquid phase and its influence on the stress field. In a further step, integrity criteria have been quantified, based on specifications of the German federal ministry of the environment. The exemplary numerical evaluation of these criteria demonstrates, how numerical simulations can be used to prove the integrity of the geological barrier and detect potential vulnerabilities.

On hospital admission numerous variables are documented from multiple trauma patients. The value of these variables to predict outcome are discussed controversially. The aim was the ability to initially determine the probability of death of multiple trauma patients. Thus, a multivariate probability model was developed based on data obtained from the trauma registry of the Deutsche Gesellschaft für Unfallchirurgie (DGU). On hospital admission the DGU trauma registry collects more than 30 variables prospectively. In the first step of analysis those variables were selected, that were assumed to be clinical predictors for outcome from literature. In a second step a univariate analysis of these variables was performed. For all primary variables with univariate significance in outcome prediction a multivariate logistic regression was performed in the third step and a multivariate prognostic model was developed. 2069 patients from 20 hospitals were prospectively included in the trauma registry from 01.01.1993-31.12.1997 (age 39 +/- 19 years; 70.0% males; ISS 22 +/- 13; 18.6% lethality). From more than 30 initially documented variables, the age, the GCS, the ISS, the base excess (BE) and the prothrombin time were the most important prognostic factors to predict the probability of death (P(death)). The following prognostic model was developed: P(death) = 1/1 + e(-[k + beta 1(age) + beta 2(GCS) + beta 3(ISS) + beta 4(BE) + beta 5(prothrombin time)]) where: k = -0.1551, beta 1 = 0.0438 with p < 0.0001, beta 2 = -0.2067 with p < 0.0001, beta 3 = 0.0252 with p = 0.0071, beta 4 = -0.0840 with p < 0.0001 and beta 5 = -0.0359 with p < 0.0001. Each of the five variables contributed significantly to the multifactorial model. These data show that the age, GCS, ISS, base excess and prothrombin time are potentially important predictors to initially identify multiple trauma patients with a high risk of lethality. With the base excess and prothrombin time value, as only variables of

The Berlin EBIT has been established by the Max-Planck-Institut fuer Plasmaphysik to generate atomic physics data in support of research in the field of controlled nuclear fusion, by measuring the radiation from highly charged ions in the x-ray, extreme ultraviolet and visible spectral ranges and providing valuable diagnostics for high temperature plasmas. In future fusion devices, for example ITER, currently being constructed at Cadarache, France, the plasma facing components will be armored with high-Z materials, most likely tungsten, due to the favorable properties of this element. At the same time the tremendous radiation cooling of these high-Z materials represents amore » threat to fusion and obliges one to monitor carefully the radiation. With EBIT a selected ensemble of ions in specific charge states can be produced, stored and excited for spectroscopic investigations. Employing this technique, we have for example resolved the wide structure observed around 5 nm at the ASDEX Upgrade tokamak as originating from E1-transitions into the open 4d shell of tungsten ions in charge states 25+ to 37+ producing a band-like emission pattern. Further, these ions emit well-separated M1 lines in the EUV range around 65 nm suitable for plasma diagnostics. Kr-like to Cr-like tungsten ions (38+ to 50+) show strong soft-x-ray lines in the range 0.5 to 2 and 5 to 15 nm. Lines of even higher charged tungsten ions, up to Ne-like W{sup 64+}, abundant in the core plasma of present and future fusion test devices, have been investigated with high resolution Bragg-crystal spectroscopy at 0.13 nm. Recently, x-ray spectroscopic measurements of the dielectronic recombination LMn resonances of W{sup 60+} to W{sup 67+} ions have been preformed and compare well with atomic structure calculations.« less
Alternative-Fuel Effects on Contrails & Cruise Emissions (ACCESS-2) Flight Experiment

2015-01-01

Although the emission performance of gas-turbine engines burning renewable aviation fuels have been thoroughly documented in recent ground-based studies, there is still great uncertainty regarding how the fuels effect aircraft exhaust composition and contrail formation at cruise altitudes. To fill this information gap, the NASA Aeronautics Research Mission Directorate sponsored the ACCESS flight series to make detailed measurements of trace gases, aerosols and ice particles in the near-field behind the NASA DC-8 aircraft as it burned either standard petroleum-based fuel of varying sulfur content or a 50:50 blend of standard fuel and a hydro-treated esters and fatty acid (HEFA) jet fuel produced from camelina plant oil. ACCESS 1, conducted in spring 2013 near Palmdale CA, focused on refining flight plans and sampling techniques and used the instrumented NASA Langley HU-25 aircraft to document DC-8 emissions and contrails on five separate flights of approx.2 hour duration. ACCESS 2, conducted from Palmdale in May 2014, engaged partners from the Deutsches Zentrum fuer Luft- und Raumfahrt (DLR) and National Research Council-Canada to provide additional scientific expertise and sampling aircraft (Falcon 20 and CT-133, respectively) with more extensive trace gas, particle, or air motion measurement capability. Eight, muliti-aircraft research flights of 2 to 4 hour duration were conducted to document the emissions and contrail properties of the DC-8 as it 1) burned low sulfur Jet A, high sulfur Jet A or low sulfur Jet A/HEFA blend, 2) flew at altitudes between 6 and 11 km, and 3) operated its engines at three different fuel flow rates. This presentation further describes the ACCESS flight experiments, examines fuel type and thrust setting impacts on engine emissions, and compares cruise-altitude observations with similar data acquired in ground tests.
New core-reflector boundary conditions for transient nodal reactor calculations

New core-reflector boundary conditions designed for the exclusion of the reflector region in transient nodal reactor calculations are formulated. Spatially flat frequency approximations for the temporal neutron behavior and two types of transverse leakage approximations in the reflector region are introduced to solve the transverse-integrated time-dependent one-dimensional diffusion equation and then to obtain relationships between net current and flux at the core-reflector interfaces. To examine the effectiveness of new core-reflector boundary conditions in transient nodal reactor computations, nodal expansion method (NEM) computations with and without explicit representation of the reflector are performed for Laboratorium fuer Reaktorregelung und Anlagen (LRA) boilingmore » water reactor (BWR) and Nuclear Energy Agency Committee on Reactor Physics (NEACRP) pressurized water reactor (PWR) rod ejection kinetics benchmark problems. Good agreement between two NEM computations is demonstrated in all the important transient parameters of two benchmark problems. A significant amount of CPU time saving is also demonstrated with the boundary condition model with transverse leakage (BCMTL) approximations in the reflector region. In the three-dimensional LRA BWR, the BCMTL and the explicit reflector model computations differ by {approximately}4% in transient peak power density while the BCMTL results in >40% of CPU time saving by excluding both the axial and the radial reflector regions from explicit computational nodes. In the NEACRP PWR problem, which includes six different transient cases, the largest difference is 24.4% in the transient maximum power in the one-node-per-assembly B1 transient results. This difference in the transient maximum power of the B1 case is shown to reduce to 11.7% in the four-node-per-assembly computations. As for the computing time, BCMTL is shown to reduce the CPU time >20% in all six transient cases of the NEACRP PWR.« less

To investigate the nature of the {{\\psi }}(3770) resonance and to measure the cross section for {{{e}}}+{{{e}}}-\\to {{D}}\\bar{{{D}}}, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha scattering events, we measure the integrated luminosity of the data sample at each center-of-mass energy point. The total integrated luminosity of the data sample is 76.16+/- 0.04+/- 0.61 {pb}}-1, where the first uncertainty is statistical and the second systematic.

Natural and False Color Views of Europa

NASA Technical Reports Server (NTRS)

1996-01-01

This image shows two views of the trailing hemisphere of Jupiter's ice-covered satellite, Europa. The left image shows the approximate natural color appearance of Europa. The image on the right is a false-color composite version combining violet, green and infrared images to enhance color differences in the predominantly water-ice crust of Europa. Dark brown areas represent rocky material derived from the interior, implanted by impact, or from a combination of interior and exterior sources. Bright plains in the polar areas (top and bottom) are shown in tones of blue to distinguish possibly coarse-grained ice (dark blue) from fine-grained ice (light blue). Long, dark lines are fractures in the crust, some of which are more than 3,000 kilometers (1,850 miles) long. The bright feature containing a central dark spot in the lower third of the image is a young impact crater some 50 kilometers (31 miles) in diameter. This crater has been provisionally named 'Pwyll' for the Celtic god of the underworld.
Europa is about 3,160 kilometers (1,950 miles) in diameter, or about the size of Earth's moon. This image was taken on September 7, 1996, at a range of 677,000 kilometers (417,900 miles) by the solid state imaging television camera onboard the Galileo spacecraft during its second orbit around Jupiter. The image was processed by Deutsche Forschungsanstalt fuer Luftund Raumfahrt e.V., Berlin, Germany.

Model calculations for the airborne Fast Ice Nuclei CHamber FINCH-HALO

Ice nuclei (IN) initiate the formation of primary ice in tropospheric clouds. In mixed phase clouds the primary ice crystals can grow very fast by the Bergeron-Findeisen process (Findeisen, 1938) at the expense of evaporating water droplets, and form precipitation. Thus, IN are essential for the development of precipitation in mixed phase clouds in the middle latitude. However, the role of IN in the development of clouds is still poorly understood and needs to be studied (Levin and Cotton, 2007). A Fast Ice Nuclei CHamber (FINCH-HALO) for airborne operation on the High And LOng Range research aircraft (HALO) is under development at the Institute for Atmosphere and Environment University Frankfurt. IN particles are activated within the chamber at certain ice super-saturation and temperature by mixing three gas flows, a warm moist, a cold dry, and an aerosol flow. After activation the particles will grow within a processing chamber. In an optical depolarisation detector droplets and ice crystals are detected separately. The setup of the new FINCH-HALO instrument is based on the ground based IN counter FINCH (Bundke, 2008). In FINCH-HALO a new cooling unit is used. Thus, measurements down to -40°C are possible. Furthermore minor changes of the inlet section where the mixing occurs were done. The contribution will present 3D model calculations with FLUENT of the flow conditions in the new inlet section for different pressure levels during a flight typical for HALO. Growth rates of ice crystals in the chamber at different temperature and super-saturation will be shown. References: Bundke U., B. Nillius, R. Jaenicke, T. Wetter, H. Klein, H. Bingemer, (2008).

Because of a lack of evidence, the appropriate timing of surgical stabilization of thoracic and lumbar spine injuries in severely injured patients is still controversial. Data of a large international trauma register were analyzed to investigate the medical care situation of unstable spinal column fractures in patients with multiple injuries, so as to examine the outcome related to timing of surgical stabilization. Data sets of the Trauma Registry of German Trauma Society (Deutsche Gesellschaft für Unfallchirurgie [DGU]) (1993-2010) were analyzed. The Trauma Registry of DGU is a prospective, multicenter register that provides information on severely injured patients. All patients with an Injury Severity Score (ISS) of 16 or greater caused by blunt trauma, subsequent treatment of 7 days or more, 16 years or older, and thoracic or lumbar spine injuries (spine Abbreviated Injury Scale [AIS] score ≥ 2) were included in our analysis. Patients with relevant spine injuries classified as having a spine AIS score of 3 or greater were further analyzed in terms of whether they got early (<72 hours) or late (>72 hours) surgical treatment due to unstable spinal column fractures. Of 24,974 patients, 8,994 (36.0%) had documented spinal injuries (spine AIS score ≥ 2). A total of 1,309 patients who sustained relevant thoracic spine injuries (spine AIS score ≥ 3) and 994 patients who experienced lumbar spine trauma and classified as having spine AIS score of 3 or greater were more precisely analyzed. Of these, 68.2% and 71.0%, respectively, received an early thoracic or lumbar spine fixation. With an increase in spinal injury severity, an increase in early stabilization in the thoracic and lumbar spine was seen. In the group of patients with early surgical stabilization, significantly shorter hospital stays, shorter intensive care unit stays, fewer days on mechanical ventilation, and lower rates of sepsis were seen. In the case that additional body regions were affected, for

White River, and the river leaving the mountain at the bottom right of the image (south) is the Nisqually River, which flows out of the Nisqually glacier on the mountain. The river leaving to the left of the mountain is the Carbon River, leading west and north toward heavily populated regions near Tacoma. The dark patch at the top right of the image is Bumping Lake. Other dark areas seen to the right of ridges throughout the image are radar shadow zones. Radar images can be used to study the volcanic structure and the surrounding regions with linear rock boundaries and faults. In addition, the recovery of forested lands from natural disasters and the success of reforestation programs can also be monitored. Ultimately this data may be used to study the advance and retreat of glaciers and other forces of global change. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: the L-band (24 cm), the C-band (6 cm) and the X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory. X-SAR was developed by the Dornier and Alenia Spazio companies for the German space agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian space agency, Agenzia Spaziale Italiana (ASI), with the Deutsche Forschungsanstalt fuer Luft und Raumfahrt e.v.(DLR), the major partner in science, operations and data processing of X-SAR.

measured (by obtaining spectra of the arcs and measuring their redshift). The masses of galaxy clusters are important for the determination, for instance of the mean density and distribution of matter in the universe. This is because these clusters are the most massive, clearly defined objects known and as such trace these parameters in the universe on very large scales. Another possibility to derive the cluster mass is offered by X-ray observations, because the distribution of the hot, X-ray emitting gas traces the gravitational field of the cluster. Recently, in some clusters there has been a discrepancy between the mass determined in this way and that found from gravitational lensing effects. The team of astronomers now hopes that follow-up X-ray observations of RXJ1347.5-1145 will help to solve this puzzle. Moreover, the combination of extremely high X-ray brightness and the possibility to perform a rather accurate mass determination by the gravitational lensing effect makes this particular cluster a truly unique object. In view of the exceptional X-ray brightness, a very high mass is expected. The exact determination will be possible, as soon as spectra have been obtained of the two arcs. Contrary to what is the case in other clusters, this will not be so difficult, due to their unusual brightness and their ideal geometrical configuration.

To study the nature of the state Y (2175), a dedicated data set of e+e- collision data was collected at the center-of-mass energy of 2.125 GeV with the BESIII detector at the BEPCII collider. By analyzing large-angle Bhabha scattering events, the integrated luminosity of this data set is determined to be 108.49±0.02±0.85 pb-1, where the first uncertainty is statistical and the second one is systematic. In addition, the center-of-mass energy of the data set is determined with radiative dimuon events to be 2126.55±0.03±0.85 MeV, where the first uncertainty is statistical and the second one is systematic.

Three dimensional perspective view of Mammoth Mountain, California

NASA Image and Video Library

1994-04-17

STS059-S-084 (17 April 1994) --- This is a three-dimensional perspective of Mammoth Mountain, California. This view was constructed by overlaying a SIR-C radar image on a U.S. Geological Survey digital elevation map. Vertical exaggeration is 2x. The image is centered at 37.6 degrees north, 119.0 degrees west. It was acquired from the Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) onboard the Space Shuttle Endeavour on its 67th orbit, April 13, 1994. In this color representation, red is C-Band HV-polarization, green is C-Band VV-polarization and blue is the ratio of C-Band VV to C-Band HV. Blue areas are smooth and yellow areas are rock outcrops with varying amounts of snow and vegetation. Crowley Lake is in the foreground and Highway 395 crosses in the middle of the image. Mammoth Mountain is shown in the upper right. SIR-C/X-SAR is part of NASA's Mission to Planet Earth (MTPE). SIR-C/X-SAR radars illuminate Earth with microwaves allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-Band (24 cm), C-Band (6 cm), and X-Band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory (JPL). X-SAR was developed by the Dornire and Alenia Spazio Companies for the German Space Agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian Space Agency, Agenzia Spaziale Italiana (ASI).

Different concepts to damp structural vibrations of the vertical tail of fighter aircraft are reported. The various requirements for a vertical tail bias an integrated approach for the design. Several active vibrations suppression concepts had been investigated during the preparatory phase of a research program shared by Daimler-Benz Aerospace Military Aircraft (Dasa), Daimler-Benz Forschung (DBF) and Deutsche Forschungsandstalt fuer Luftund Raumfahrt (DLR). Now in the main phase of the programme, four concepts were finally chosen: two concepts with aerodynamic control surfaces and two concepts with piezoelectric components. One piezo concept approach will be described rigorously, the other concepts are briefly addressed. In the Dasa concept, thin surface piezo actuators are set out carefully to flatten the dynamic portion of the combined static and dynamic maximum bending moment loading case directly in the shell structure. The second piezo concept by DLR involves pre-loaded lead zirconate titanate (PZT)-block actuators at host structure fixtures. To this end a research apparatus was designed and built as a full scale simplified fin box with carbon fiber reinformed plastic skins and an aluminium stringer-rib substructure restrained by relevant aircraft fixtures. It constitutes a benchmark 3D-structural impedance. The engineering design incorporates 7kg of PZT surface actuators. The structural system then should be excited to more than 15mm tip displacement amplitude. This prepares the final step to total A/C integration. Typical analysis methods using cyclic thermal analogies adapted to induced load levels are compared. Commercial approaches leading onto basic state space model interpretation wrt. actuator sizing and positioning, structural integrity constraints, FE-validation and testing are described. Both piezoelectric strategies are aimed at straight open-loop performance related to concept weight penalty and input electric power. The required actuators, power

2012-02-01

The following talk has been given in a special session dedicated to Professor Heinz-Dietrich Doebner at QTS in Prague in August 2011 on the occasion of his 80th birthday. It documents my journey from being a PhD student in Mathematical Physics at the Arnold Sommerfeld Institute in Clausthal under his supervision, to becoming a Professor of Mathematical Biology at the University of York in the UK. I am currently heading an interdisciplinary research group of eight PDRAs and PhDs, focussed on investigating the structures of viruses from a symmetry perspective and unravelling the implications of virus structure on how viruses form and infect their hosts. A central element in my research is my fascination with the development and application of symmetry techniques, which stems from my time in Clausthal when working with Professor Doebner and colleagues. I would like to thank Professor Doebner for these important formative years in Clausthal. Der folgende Vortrag war mein Beitrag zu einer Festsitzung fuer Herrn Professor Heinz-Dietrich Doebner auf der Tagung QTS im August 2011 anläßlich seines achzigsten Geburtstags. Dieser Beitrag dokumentiert, wie sich meine Forschungen aus der Zeit als Doktorandin von Herrn Professor Doebner in Mathematischer Physik am Arnold Sommerfeld Institut in Clausthal weiterentwickelt haben, und zu meiner Professur in Mathematischer Biologie an der Universität York geführt haben. Ich leite dort zur Zeit eine interdisziplinäre Forschungsgruppe von acht Postdocs und Doktoranden, die sich mit der Entwicklung und Anwendung von Symmetrie-Techniken in der Virologie beschäftigt, und insbesondere untersucht, wie sich die Symmetrie-Eigenschaften von Viren auf deren Entstehung und Funktionsweise auswirken. Eine wichtige Vorraussetzung für dieses Forschungsprogramm ist meine Faszination für die Modellierung von Symmetrie-Eigenschaften, die ich während meiner Zusammenarbeit mit Herrn Professor Doebner und Kollegen in Clausthal entwickelt habe

A measurement of the number of J/ψ events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/ψ. The number of J/ψ events taken in 2009 is recalculated to be (223.7 ± 1.4) × 106, which is in good agreement with the previous measurement, but with significantly improved precision due to improvements in the BESIII software. The number of J/ψ events taken in 2012 is determined to be (1086.9 ± 6.0) × 106. In total, the number of J/ψ events collected with the BESIII detector is measured to be (1310.6 ± 7.0) × 106, where the uncertainty is dominated by systematic effects and the statistical uncertainty is negligible.

Dynamical downscaling of wind fields for wind power applications H.-T. Mengelkamp*,**, S. Huneke**, J, Geyer** *GKSS Research Center Geesthacht GmbH **anemos Gesellschaft für Umweltmeteorologie mbH Investments in wind power require information on the long-term mean wind potential and its temporal variations on daily to annual and decadal time scales. This information is rarely available at specific wind farm sites. Short-term on-site measurements usually are only performed over a 12 months period. These data have to be set into the long-term perspective through correlation to long-term consistent wind data sets. Preliminary wind information is often asked for to select favourable wind sites over regional and country wide scales. Lack of high-quality wind measurements at weather stations was the motivation to start high resolution wind field simulations The simulations are basically a refinement of global scale reanalysis data by means of high resolution simulations with an atmospheric mesoscale model using high-resolution terrain and land-use data. The 3-dimensional representation of the atmospheric state available every six hours at 2.5 degree resolution over the globe, known as NCAR/NCEP reanalysis data, forms the boundary conditions for continuous simulations with the non-hydrostatic atmospheric mesoscale model MM5. MM5 is nested in itself down to a horizontal resolution of 5 x 5 km². The simulation is performed for different European countries and covers the period 2000 to present and is continuously updated. Model variables are stored every 10 minutes for various heights. We have analysed the wind field primarily. The wind data set is consistent in space and time and provides information on the regional distribution of the long-term mean wind potential, the temporal variability of the wind potential, the vertical variation of the wind potential, and the temperature, and pressure distribution (air density). In the context of wind power these data are used �

The need for a defendable and systematic uncertainty and sensitivity approach that conforms to the Code Scaling, Applicability, and Uncertainty (CSAU) process, and that could be used for a wide variety of software codes, was defined in 2008. The GRS (Gesellschaft für Anlagen und Reaktorsicherheit) company of Germany has developed one type of CSAU approach that is particularly well suited for legacy coupled core analysis codes, and a trial version of their commercial software product SUSA (Software for Uncertainty and Sensitivity Analyses) was acquired on May 12, 2010. This report summarized the results of the initial investigations performed with SUSA,more » utilizing a typical High Temperature Reactor benchmark (the IAEA CRP-5 PBMR 400MW Exercise 2) and the PEBBED-THERMIX suite of codes. The following steps were performed as part of the uncertainty and sensitivity analysis: 1. Eight PEBBED-THERMIX model input parameters were selected for inclusion in the uncertainty study: the total reactor power, inlet gas temperature, decay heat, and the specific heat capability and thermal conductivity of the fuel, pebble bed and reflector graphite. 2. The input parameters variations and probability density functions were specified, and a total of 800 PEBBED-THERMIX model calculations were performed, divided into 4 sets of 100 and 2 sets of 200 Steady State and Depressurized Loss of Forced Cooling (DLOFC) transient calculations each. 3. The steady state and DLOFC maximum fuel temperature, as well as the daily pebble fuel load rate data, were supplied to SUSA as model output parameters of interest. The 6 data sets were statistically analyzed to determine the 5% and 95% percentile values for each of the 3 output parameters with a 95% confidence level, and typical statistical indictors were also generated (e.g. Kendall, Pearson and Spearman coefficients). 4. A SUSA sensitivity study was performed to obtain correlation data between the input and output parameters, and to

reveals that high values of B are not restricted by the Hubble type and even dwarf (starbursting) galaxies can produce strong magnetic fields. However, weaker fields appear exclusively in later Hubble types and B as low as about 5 μG is not seen among typical spirals. Conclusions: The processes of generation of magnetic field in the dwarf and Magellanic-type galaxies are similar to those in the massive spirals and starbursts and are mainly coupled to local star-formation activity involving the small-scale dynamo mechanism.

Multiple injured patients, polytrauma or severely injured patients are terms used as synonyms in international literature describing injured patients with a high risk of mortality and cost consuming therapeutic demands. In order to advance the definition of these terms, we analysed a large trauma registry. In detail, we compared critically ill trauma patients first specified on a pure anatomical base according to the ISS or NISS, second in the original "polytrauma definition" with two body regions affected and finally all of them combined with a physiological component. Records that were collected in the TraumaRegister DGU(®) of the German Trauma Society (Deutsche Gesellschaft für Unfallchirurgie, DGU) between 1993 and 2011 (92,479 patients) were considered for this study. All patients with primary admission from scene with a minimum hospital stay of 48 h and an Injury Severity Score (ISS)≥ 16 were included. Pre-hospital and early admission data were used to determine physiological risk factors and calculate individual risk of death using the Revised Injury Severity Classification (RISC). 45,350 patients met inclusion criteria. The overall hospital mortality rate was 20.4%. The predicted mortality according to the RISC-Score was 21.6%. 36,897 patients (81.4%) had injuries in several body regions. The prevalence of the five physiological risk factors varied between 17% (high age) and 34% (unconsciousness). There were 17,617 patients (38.8%) without any risk factor present on admission, while 30.6% (n=13,890) of the patients had one and 30.5% (n=13,843) had two or more factors present. Patients with ISS ≥ 16 but no physiological risk factor present had a very low mortality rate of 3.1% (542 of 17,617). With an increasing number of physiological factors there was an almost linear increase in mortality up to an 86% rate in patients with all five factors present.

The Vertical Circle (81/1200 mm) was used as an auxiliary instrument for the meridian circle and for measuring polar motion. It is a rare instrument and only very few are still in existence at European observatories. Originally the Heliometer (217/3000 mm) was an instrument for measuring very small distances at the celestial sphere. Of this type of instrument, the Vienna heliometer was the largest in the world. It was installed at the observatory in 1896 and was mainly used for measuring the trigonometric parallaxes of the stars. Of 108 known parallaxes in 1910, 16 stars were measured at Kuffner Observatory at that time.

Kugel, Karin; Steyer, Stefan; Brennecke, Peter

In addendum 4 to the license of the German KONRAD repository, which considers mainly radiological aspects, a water law permit was issued in order to prevent the pollution of the near-surface groundwater. The water law permit stipulates limitations for 10 radionuclides and 2 groups of radionuclides as well as mass limitations for 94 substances and materials relevant for water protection issues. Two collateral clauses, i.e. additional requirements imposed by the licensing authority, include demands on the monitoring, registering and balancing of non-radioactive harmful substances and materials /1/. In order to fulfill the requirements of the water law permit the Germanmore » Federal Office for Radiation Protection (BfS) being the operator of the KONRAD repository has developed a concept, which ensures the compliance with all requirements of the water law permit and which provides standardized easy manageable guidance for the waste producers to describe their wastes. On 15 March 2011 the competent water authority, the 'Niedersaechsischer Landesbetrieb fuer Wasserwirtschaft, Kuesten- und Naturschutz' (NLWKN) issued the approval for this concept. Being the most essential part of this concept the procedural method and the developed description of nonradioactive waste package constituents by use of standardized lists of materials and containers is addressed and presented in this paper. The waste producer has to describe his waste package in a standardized way on the base of the lists of materials and containers. For each material in the list a comprehensive description is given comprising the composition, scope of application, quality control measures, thresholds and other data. Each entry in the list has to be approved by NLWKN. The scope of the lists is defined by the waste producers' needs. Using some particular materials as examples, the approval procedure for including materials in the list is described. The procedure of describing the material composition has to

A 2 MV Van de Graaff accelerator as a tool for planetary and impact physics research

Mocker, Anna; Bugiel, Sebastian; Srama, Ralf

Investigating the dynamical and physical properties of cosmic dust can reveal a great deal of information about both the dust and its many sources. Over recent years, several spacecraft (e.g., Cassini, Stardust, Galileo, and Ulysses) have successfully characterised interstellar, interplanetary, and circumplanetary dust using a variety of techniques, including in situ analyses and sample return. Charge, mass, and velocity measurements of the dust are performed either directly (induced charge signals) or indirectly (mass and velocity from impact ionisation signals or crater morphology) and constrain the dynamical parameters of the dust grains. Dust compositional information may be obtained via either time-of-flightmore » mass spectrometry of the impact plasma or direct sample return. The accurate and reliable interpretation of collected spacecraft data requires a comprehensive programme of terrestrial instrument calibration. This process involves accelerating suitable solar system analogue dust particles to hypervelocity speeds in the laboratory, an activity performed at the Max Planck Institut fuer Kernphysik in Heidelberg, Germany. Here, a 2 MV Van de Graaff accelerator electrostatically accelerates charged micron and submicron-sized dust particles to speeds up to 80 km s{sup -1}. Recent advances in dust production and processing have allowed solar system analogue dust particles (silicates and other minerals) to be coated with a thin conductive shell, enabling them to be charged and accelerated. Refinements and upgrades to the beam line instrumentation and electronics now allow for the reliable selection of particles at velocities of 1-80 km s{sup -1} and with diameters of between 0.05 {mu}m and 5 {mu}m. This ability to select particles for subsequent impact studies based on their charges, masses, or velocities is provided by a particle selection unit (PSU). The PSU contains a field programmable gate array, capable of monitoring in real time the particles' speeds

It is well demonstrated that small aerosol particles or particulate matter (PM10 and PM2.5) affect air quality and can have severe effects on human's health. Hence, it is of great interest for public institutions to have an efficient PM monitoring network. In the last decades this data has been provided from ground-based instruments. Moreover, due to the fast development of space-borne remote sensing instruments, we can now be able to take advantage of air pollution measurements from space, which bears the potential to fill up the gap of spatial coverage from ground-based networks. This also improves the capability to assess air pollutants transport properties together with a better implementation in forecasting data assimilation procedures. In this study we examine the possibility of using data from the Spinning Enhanced Visible and Infrared Imager (SEVIRI), on-board of the geostationary Meteosat Second Generation (MSG) platform, to provide PM concentrations values over Switzerland. SEVIRI's high temporal resolution (15 minutes) could be very useful in investigating the daily behaviour of air pollutants and therefore be a good complement to measurements from polar orbiting sensors (e.g. MODIS). Switzerland is of particular interest because of its mountainous orography that hampers pollutants dispersion. Further, major transalpine connection routes, often characterised by high traffic load, act as a significant air pollution source. The south of Switzerland is also occasionally influenced by pollutants transported from the highly industrialised Po Valley in northern Italy. We investigate the existence of a linear relation between the SEVIRI retrieved AOD (Aerosol Optical Depth) and the PM concentration obtained from the ground-based air quality network NABEL (Nationales Beobachtungsnetz fuer Luftfremdstoffe). The temporal trend of this two quantities shows a significant relationship over various locations. The correlation coefficient is in some cases higher than 0

natural fluoride content of drinking water either had no influence on dental health at all, or this influence is so diminutive that it is exceeded by far by sociodemographic factors. Obviously there is much more fluoride available from other sources nowadays compared to 30 years ago. The results may also have implications for the administration of fluoride tablets and support the recommendations of the DGZMK (Deutsche Gesellschaft für Zahn-, Mund- und Kieferheilkunde) from the year 2000, restricting the administration of fluoride tablets to special situations following an individual anamnesis of fluoride uptake. © Georg Thieme Verlag KG Stuttgart · New York.

In April 2016, the German Society of Hygiene, Environmental Medicine and Preventative Medicine (Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin (GHUP)) together with other scientific medical societies, German and Austrian medical societies, physician unions and experts has provided an AWMF (Association of the Scientific Medical Societies) guideline 'Medical diagnostics for indoor mold exposure'. This guideline shall help physicians to advise and treat patients exposed indoors to mold. Indoor mold growth is a potential health risk, even without a quantitative and/or causal association between the occurrence of individual mold species and health effects. Apart from the allergic bronchopulmonary aspergillosis (ABPA) and the mycoses caused by mold, there is only sufficient evidence for the following associations between moisture/mold damages and different health effects: Allergic respiratory diseases, asthma (manifestation, progression, exacerbation), allergic rhinitis, exogenous allergic alveolitis and respiratory tract infections/bronchitis. In comparison to other environmental allergens, the sensitizing potential of molds is estimated to be low. Recent studies show a prevalence of sensitization of 3-10% in the total population of Europe. The evidence for associations to mucous membrane irritation and atopic eczema (manifestation, progression, exacerbation) is classified as limited or suspected. Inadequate or insufficient evidence for an association is given for COPD, acute idiopathic pulmonary hemorrhage in children, rheumatism/arthritis, sarcoidosis, and cancer. The risk of infections from indoor molds is low for healthy individuals. Only molds that are capable to form toxins can cause intoxications. The environmental and growth conditions and especially the substrate determine whether toxin formation occurs, but indoor air concentrations are always very low. In the case of indoor moisture/mold damages, everyone can be affected by odor effects and

Traditionally, in the German-speaking countries, trauma patients are treated by general surgeons specialized in trauma surgery known as the Unfallchirurg. Over the last decade, a trend towards a lower influence of surgeons and a higher influence of subspecialties in the emergency department has been noted. With additional transformations in the health care system towards highly specialized medicine and the arising of new (sub-) specialties, diversification in the management of the trauma patient appears to occur. The new curricula for surgical disciplines providing trauma care will widen this issue even further, moreover, triggered by the Anglo-American medical model. The primary aim of this study was to evaluate the current situation in German-speaking countries concerning the management of trauma patients. The interfaces between emergency physicians, orthopaedic and general surgeons have been investigated concerning the management of the trauma patients. Additionally, different future scenarios have been evaluated. An online questionnaire was submitted to members of the German Society of Trauma and Orthopaedic Surgery [Deutsche Gesellschaft für Orthopädie und Unfallchirurgie (DGOU)], including both general and orthopaedic surgeons, emergency physicians and also some members from Austria, the Netherlands and Switzerland. Questions dealt with demographic data, the current situation in the clinic of the responders in terms of management of mono- and polytrauma patients as well as fracture care. In addition, various future scenarios were evaluated. 293 members of the DGOU answered the questionnaire. The majority of the responders (45%) were orthopaedic surgeons and 34% were general trauma surgeons. Sixty-two per cent of hospitals run their emergency departments with emergency physicians. Treatment of both mono- and polytrauma patients in the emergency department is equally distributed between general and orthopaedic surgeons. Fracture care, however, is

Practice guidelines are systematically developed statements and recommendations that assist the physicians and patients in making decisions about appropriate health care measures for specific clinical circumstances taking into account specific national health care structures. The 1st revision of the S-2k guideline of the German Sepsis Society in collaboration with 17 German medical scientific societies and one self-help group provides state-of-the-art information (results of controlled clinical trials and expert knowledge) on the effective and appropriate medical care (prevention, diagnosis, therapy and follow-up care) of critically ill patients with severe sepsis or septic shock. The guideline had been developed according to the “German Instrument for Methodological Guideline Appraisal” of the Association of the Scientific Medical Societies (AWMF). In view of the inevitable advancements in scientific knowledge and technical expertise, revisions, updates and amendments must be periodically initiated. The guideline recommendations may not be applied under all circumstances. It rests with the clinician to decide whether a certain recommendation should be adopted or not, taking into consideration the unique set of clinical facts presented in connection with each individual patient as well as the available resources.

During National Socialism, the politically motivated interest in psychiatric genetic research lead to the founding of research departments specialized in pathological-anatomical brain research, the two Kaiser Wilhelm-Institutes (KWI) in Berlin and Munich. The latter was indirectly provided with brain material by Bavarian State Hospitals, to three of which "Kinderfachabteilungen" (Special Pediatric Units) were affiliated. As children became victims of the systematically conducted child "euthanasia" in these Special Pediatric Units, this paper will address the question whether and to which extent the organs from victims of child "euthanasia" were used for (neuro-) pathological research at the KWI in Munich. By means of case studies and medical histories (with focus on the situation in Kaufbeuren-Irsee), I will argue that pediatric departments on a regular base delivered slide preparations, that the child "euthanasia" conduced in these departments systematically contributed to neuropathological research and that slide preparations from victims of child "euthanasia" were used in scientific publications after 1945.

Replacement of the in vivo neutralisation test for efficacy demonstration of tetanus vaccines ad us. vet.

The bacterium Clostridium (C.) tetani is an ubiquitous pathogen. This anaerobic, gram-positive bacterium can form spores and can be found in the whole environment. It enters the body via injuries of the skin and wounds where it releases the neurotoxin "tetanospasmin" (= tetanus toxin). The animals most susceptible to tetanus infection are horses and sheep. Only active immunisation by tetanus vaccine provides effective protection against tetanus intoxication. The marketing authorisation requirements stipulate that efficacy of tetanus vaccines ad us. vet. must be demonstrated in all target animal species via determination of neutralising tetanus serum antitoxin concentrations. The standard method used for this purpose is still the toxin neutralisation test (TNT), as it quantifies the tetanus toxin-neutralising effect of tetanus serum antibodies in vivo. In this test, tetanus toxin is added to dilutions of serum from vaccinated horse and sheep. The serum dilutions are then administered to mice or guinea pigs, which are observed for toxic symptoms. Against the background of animal protection, the goal of one project of the Paul-Ehrlich-Institut (Bundesministerium fuer Bildung und Forschung (Federal Ministry for Education and Research), 0312636) was to establish an alternative to the toxin neutralisation test, enabling the testing of efficacy of tetanus vaccines with serological in vitro methods. For this purpose, a so-called double antigen ELISA (DAE) was established which enables the testing of sera of different species in one assay. In addition, the sera were tested in an indirect ELISA for horses and sheep separately. Altogether, ten groups of horses and eight groups of sheep were immunised with ten animals per group each. The tetanus vaccines comprised almost all products authorised for the German market at the start of the project. 564 horse sera and 257 sheep sera were tested using the two ELISA methods. Some sera were also tested in vivo. The kinetics of

The theory of atomic Boson-Fermion mixtures in the dilute limit beyond mean-field is considered in this thesis. Extending the formalism of quantum field theory we derived expressions for the quasi-particle excitation spectra, the ground state energy, and related quantities for a homogenous system to first order in the dilute gas parameter. In the framework of density functional theory we could carry over the previous results to inhomogeneous systems. We then determined to density distributions for various parameter values and identified three different phase regions: (i) a stable mixed regime, (ii) a phase separated regime, and (iii) a collapsed regime. We found a significant contribution of exchange-correlation effects in the latter case. Next, we determined the shift of the Bose-Einstein condensation temperature caused by Boson-Fermion interactions in a harmonic trap due to redistribution of the density profiles. We then considered Boson-Fermion mixtures in optical lattices. We calculated the criterion for stability against phase separation, identified the Mott-insulating and superfluid regimes both, analytically within a mean-field calculation, and numerically by virtue of a Gutzwiller Ansatz. We also found new frustrated ground states in the limit of very strong lattices. ----Anmerkung: Der Autor ist Träger des durch die Physikalische Gesellschaft zu Berlin vergebenen Carl-Ramsauer-Preises 2004 für die jeweils beste Dissertation der vier Universitäten Freie Universität Berlin, Humboldt-Universität zu Berlin, Technische Universität Berlin und Universität Potsdam.

Introduction Etching of enamel and dentin surfaces increases the surface area of the substrate for better bonding of the tooth colored restorative materials. Acid etching is the most commonly used method. Recently, hard tissue lasers have been used for this purpose. Aim The aim of the present study was to evaluate and compare the etching pattern of Er,Cr:YSGG and conventional etching on extracted human enamel and dentin specimens. Materials and Methods Total 40 extracted non-diseased teeth were selected, 20 anterior and 20 posterior teeth each for enamel and dentin specimens respectively. The sectioned samples were polished by 400 grit Silicon Carbide (SiC) paper to a thickness of 1.0 ± 0.5 mm. The enamel and dentin specimens were grouped as: GrE1 & GrD1 as control specimens, GrE2 & GrD2 were acid etched and GrE3 & GrD3 were lased. Acid etching was done using Conditioner 36 (37 % phosphoric acid) according to manufacturer instructions. Laser etching was done using Er,Cr:YSGG (Erbium, Chromium : Ytrium Scandium Gallium Garnet) at power settings of 3W, air 70% and water 20%. After surface treatment with assigned agents the specimens were analyzed under ESEM (Environmental Scanning Electron Microscope) at X1000 and X5000 magnification. Results Chi Square and Student “t” statistical analysis was used to compare smear layer removal and etching patterns between GrE2-GrE3. GrD2 and GrD3 were compared for smear layer removal and diameter of dentinal tubule opening using the same statistical analysis. Chi-square test for removal of smear layer in any of the treated surfaces i.e., GrE2-E3 and GrD2-D3 did not differ significantly (p>0.05). While GrE2 showed predominantly type I etching pattern (Chi-square=2.78, 0.05
0.10) and GrE3 showed type III etching (Chi-square=4.50, p<0.05). The tubule diameters were measured using GSA (Gesellschaft fur Softwareentwicklung und Analytik, Germany) image analyzer and the ‘t’ value of student ‘t’ test was 18.10 which was a

The author of this essay, Hermann Alexander Brück, Emeritus Professor of Astronomy at the University of Edinburgh and former Astronomer Royal for Scotland, died on 4 March 2000 in his 95th year. He was the last of his generation of astronomers in both Germany and Britain, and among the oldest members, if not the oldest, of the Royal Astronomical Society and of the Astronomische Gesellschaft. Hermann Brück was born in Berlin in 1905 and, as he recounts below, received his education at the Universities of Kiel, Bonn and Munich in 1924-1928. To the end of his life he looked back on his student days in Munich as the most profitable and exciting he ever experienced. From Munich he began his astronomical career at the Potsdam Astrophysical Observatory. These, too, were happy days, destined, however, to be blighted within a few years by the rise of Nazism. In 1936 Brück left Germany, and obtained a temporary Research Assistantship at the Vatican Observatory. From there he went a year later to Cambridge, rising to the rank of John Couch Adams Astronomer and Assistant Director of the Observatory. In 1947, in response to an invitation from Eamon de Valera, then Taoiseach (Prime Minister) of Ireland, he moved to Dublin where he undertook the task of re-founding the defunct Dunsink Observatory under the auspices of the Dublin Institute for Advanced Studies. He moved from Dublin to the Royal Observatory Edinburgh in 1957, taking up the combined post of Astronomer Royal for Scotland and Regius Professor of Astronomy in the University of Edinburgh. He retired in 1975 at the age of 70. Always interested in history, he occupied himself in his retirement with various historical projects. These included writing the histories of the Royal Observatory Edinburgh (The Story of Astronomy in Edinburgh, Edinburgh 1983) and of the earlier Dun Echt Observatory in Aberdeenshire (Lord Crawford's Observatory at Dun Echt 1872-1892, Vistas in Astronomy 35, 1992) as well as a record of his own

in Western Gondwana margin. Powdered microsamples have been analysed for their elemental and isotopic composition (δ13C values range from + 0.41 to + 3.05). Sulphur minerals and silicates where analyzed with XRD and wavelength-dispersive electron microprobe. Major elements were measured with ICP-OES and minor and trace elements were analyzed with ICP-MS. These are the first palaeontological, sedimetological, geochemical and isotopical data provided to reconstruct the depositional environment of these Archaeocyath-rich facies at the Western Gondwana margin.

saturated (grey value 255). With reduced illumination intensity "carbonate image pixels" get unsaturated and can be well distinguished from quartz grains. During the evaluation process we identify all falsely classified areas using neighbourhood matrices and reclassify them. Finally, we use filter techniques to derive downcore component frequencies from the classified thin section images for variable thick virtual samples. The filter conducts neighbourhood analyses. After filtering, each pixel of the filtered images carries the information about the frequency of any given component in a defined neighbourhood around (virtual sampling). References Rein, B.

means. Spaceborne Imaging Radar-C and X-Synthetic Aperture Radar (SIR-C/X-SAR) are part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm), and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes that are caused by nature and those changes that are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory. X-SAR was developed by the Dornier and Alenia Spazio companies for the German space agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian space agency, Agenzia Spaziale Italiana (ASI), with the Deutsche Forschungsanstalt fuer Luft und Raumfahrt e.v.(DLR), the major partner in science, operations and data processing of X-SAR.

variability with a 11 fold concentration range (50-550 mg CE L-1) while variability of anthocyanins was lower with a 3 fold concentration range (90-250 mg M3OG L-1). The results showed that differences in leaf chlorophyll (SFR_G) would represent the most important factor influencing wine phenolic composition. Measurements of soil resistivity based on ARP technique (Geocarta, Paris, France), leaf composition with a mounted Multiplex providing information on porosity (NFI), biomass (BIOMASS) and chlorophyll (BISFR) together with NDVI assessed by geo-X8000 (geo-konzept-Gesellschaft für Umweltplanungssysteme mbH, Adelschlag, Germany) were performed. Grapes and berry composition was also assessed with Mx3 providing information on anthocyanins (ANTH, FERARI) and sugar (SFR_R) variability. In a second step, vines similar in size (trunk diameter and cane number) and similar yield (number of bunches per vines) were divided in 3 groups differing in leaf SFR_G. A larger scale winemaking (150kg) showed that with increasing SFR_G, Pinot noir wine typicity decreased together with anthocyanin concentration while tannin concentration increased. A better understanding of vineyard variability for targeted management or harvest would allow better understanding to produce and select fruit to a favored wine style.

results are compared to corresponding theoretic and experimental results. The model is applied to study the influence of pore sizes and pore structure as well as of electrolyte properties like ion mobilities and concentrations. We find two characteristic phase minima in the frequency range 1mHz - 100MHz. The dependence of the 'high frequency' minimum (f > 10kHz) on the electrolyte concentration and the dependence of the corresponding relaxation times on variations of the pore geometry are in good agreement with the classical Maxwell-Wagner theory. In contrast to this effective medium approach the simulations confirm the necessity of pore throats to obtain non-vanishing phase values. For large size differences of the smaller and larger pores a second 'low frequency' minimum (f < 10kHz) exists. Its relaxation time mainly depends on the length of the large pores of the system. Furthermore we find a decreasing phase amplitude with increasing electrolyte concentration not predicted by Marshall and Madden and similar models but confirmed by experimental results. This study was conducted within the Transregional Collaborative Research Centre 32 (SFB TR 32; subproject A2), funded by the German Research Foundation (DFG).

The radar system has been mounted on a DJI 550 UAV, a flexible hexacopter allowing both complex flight operations and static flight, and has been equipped with small size log-periodic antennas, having a 6 dB gain over the frequency range from 2 GHz to 11 GHz. An ad-hoc signal processing chain has been adopted to process the collected raw data and obtain an image of the investigated scenario providing an accurate target detection and localization. This chain involves a SVD-based noise filter procedure and an advanced data processing approach, which assumes a linear model of the underlying scattering phenomenon. REFERENCES [1] K. Whitehead, C.

We additionally measured the B-concentration in the sample to prove our predictions of the B-concentration needed to reach sufficient conductibility for the sample not getting electrostatically charged during instrument operation. The results of narrower scattering cones and higher ionisation efficiency show that diamond-like carbon still is the preferred material for charge state conversion surfaces and that new surface technologies offer improved diamond conversion surfaces with different properties and hence the possibility for improvement of the performance of neutral atom imaging instruments.

Disaster control and disaster relief in Germany are public tasks. But the government has shifted the responsibility of the administration of these tasks to the 16 states, the so called "Lander", because the EFG is a federal republic. The same is valid for the civil defense and the civil protection in the case of military or international risks. The 16 states are also responsible for the legislation of rescue service, fire fighting service and disaster control (natural and technical disasters). Counties and district-free cities are responsible for the organisation of these services. The German system is based on the principle of subsidiary between official and private institutions. A lot of official and private relief organisations are responsible for the execution of disaster relief tasks. In Germany the following organisations exist: Official (GO): Technisches Hilfswerk (THW/Federal Technical Support Service), Feuerwehren (Fire Brigades/professionals and volunteers) Academie of Emergency Planning and Civil Defense Private (NGO): Arbeiter-Samariter-Bund Deutschland (ASB/Workers' Samaritan Association Germany), Deutsche Gesellschaft zur Rettung Schiffbruchiger (DGzRS, German Lifesaving Association), Deutsches Rotes Kreuz (DRK/German Red Cross), Johanniter-Unfall-Hilfe (JUH/St. John's Ambulance), Malteser Hilfsdienst (MEID/Maltese-Relief-Organisation). ASB, DRK, JUH and MHD are specialised in the field of rescue, medical and welfare services and medical disaster relief. 80% of the German rescue service and 95% of the German disaster medical relief are realised by these NGO's. NGO's and GO's employ more than 1.2 million volunteers and appr. 100,000 professionals. Rescue service is carried out by professionals, disaster relief by volunteers. The German constitution allows to call the federal army in case of disaster, to support the disaster relief organisations (for example: flood Oder River 1997, train-crash "ICE" 1998).

The Joint European and National Astronomy Meeting 2008 (JENAM 2008) was held from September 8-12, 2008 in Vienna, Austria, as the joint meeting of the Austrian Society of Astronomy and Astrophysics (ÖGAA), the Astronomische Gesellschaft (AG), and the European Astronomical Society (EAS). It hosted nine symposia under the overall topic ''New Challenges To European Astronomy''. This special volume of Communications in Asteroseismology holds the proceedings of the JENAM 2008 Symposium No 4: ''Asteroseismology and Stellar Evolution''. The Asteroseismology and Stellar Evolution Symposium has been generously sponsored by the ÖGAA, by the HELAS Forum (an activity of the European Helio- and Asteroseismology Network, initiative funded by the European Commission since April 1st, 2006, as a Co-ordination Action under its Sixth Framework Programme, FP6), and by the Kulturabteilung der Stadt Wien (Magistratsabteilung 7). The Symposium program was put together by the Scientific Organizing Committee consisting of Conny Aerts (University of Leuven, Belgium), Annie Baglin (Observatoire de Paris, France), Wolfgang Glatzel (University of Göttingen, Germany), Gerald Handler (University of Vienna, Austria, Co-convener), Uli Heber (University of Erlangen-Nürnberg, Germany), Katrien Kolenberg (University of Vienna, Austria), Suzanna Randall (European Southern Observatory) and Sonja Schuh (University of Göttingen, Germany, Convener). Out of a total of 60 oral and poster contributions, 15 contributed talks were selected for presentation during the three half-day session program, with ample time for questions and discussion. There also was an opportunity to introduce the poster contributions during 2-min oral presentations. The scientific topics covered diverse object classes divided into Stochastically excited pulsators (main sequence, red giants, AGB supergiants), Heat-driven pulsators along the main sequence, and Compact pulsators, as well as additional topics that we have summarized

vicinity of the nucleus. Evidence of moderate, AGN-driven radio activity is also found in both sources. Based on the estimated stellar and black hole masses, the two sources lie on the local M_BH{-}M_bulge relation. To remain on this relation as they evolve, their star formation rate has to decrease or stop. Our results support evolutionary models that invoke radio feedback such as the star formation quenching mechanism, and suggest that such a mechanism might play a major role also in powerful AGNs. This paper makes use of observations collected at the European Southern Observatory, Chile, ESO program No. 079.A-0522(A), and at the IRAM 30 m-Telescope.

identification of main flux driving parameters. Based on this procedure we developed a specific methane efflux model, mainly driven by the observed groundwater fluctuation and soil temperature. Depending on the observed timescale initial starting points of the model showed up to be remarkably different. We also will present suggestions for an advanced CO2 modelling as the present approaches are both based on single parameters. Generally our experiences from our field studies show that mono-parameterized models often fail in reproducing measured flux values.

order to validate these estimations, the resulting sediment transfer rates are compared to transfer rates calculated from repeated terrestrial LiDAR surveys on selected study cases. This contribution presents results from the application of this methodology in a test study area in the south-western Swiss Alps. The methodology reveals itself suitable to identify rock glaciers connected to the torrential network. For each of the detected rock glaciers, an estimation of the sediment yield is proposed. The transfer rates range from tens of cubic meters per year for some slow moving and/or partially connected landforms, to several thousands of cubic meters per year. References: Delaloye R. (2004).

New fission track ages, complementing the published ones, will be used to obtain a detailed 3D pattern of cooling, especially in the central TW. This pattern, combined with a thermal model, will allow us to discuss the relative importance of the afore mentioned two end-members exhumation mechanisms and to relate them to the temporal evolution of the exhumation processes.

, will be built at a high-altitude, extremely dry mountain site in Chile's Atacama desert. The array is scheduled to be completed sometime in this decade. Millimeter-wave astronomy studies the universe in the spectral region where most of its energy lies, between the long-wavelength radio waves and the shorter-wavelength infrared waves. In this realm, ALMA will study the structure of the early universe and the evolution of galaxies; gather crucial data on the formation of stars, protoplanetary disks, and planets; and provide new insights on the familiar objects of our own solar system. "Most of the photons in the Universe lie in the millimeter wavelength regime; among existing or planned instruments only ALMA can image the sources of these photons with the crispness required to understand the events of galaxy, star and planet formation which launched them into space," said NRAO's Dr. Alwyn Wootten, U.S. ALMA Project Scientist. ALMA is an international partnership between the United States (National Science Foundation) and Europe. European participants include the European Southern Observatory, the Centre National de la Recherche Scientifique (France), the Max-Planck Gesellschaft (Germany), the Netherlands Foundation for Research in Astronomy, the United Kingdom Particle Physics and Astronomy Research Council, the Oficina de Ciencia Y Tecnologia/Instituto Geografico Nacional (Spain), and the Swedish Natural Science Research Council.

Use of meteorological information in the risk analysis of a mixed wind farm and solar power plant portfolio H.-T. Mengelkamp*,** , D. Bendel** *GKSS Research Center Geesthacht GmbH **anemos Gesellschaft für Umweltmeteorologie mbH The renewable energy industry has rapidly developed during the last two decades and so have the needs for high quality comprehensive meteorological services. It is, however, only recently that international financial institutions bundle wind farms and solar power plants and offer shares in these aggregate portfolios. The monetary value of a mixed wind farm and solar power plant portfolio is determined by legal and technical aspects, the expected annual energy production of each wind farm and solar power plant and the associated uncertainty of the energy yield estimation or the investment risk. Building an aggregate portfolio will reduce the overall uncertainty through diversification in contrast to the single wind farm/solar power plant energy yield uncertainty. This is similar to equity funds based on a variety of companies or products. Meteorological aspects contribute to the diversification in various ways. There is the uncertainty in the estimation of the expected long-term mean energy production of the wind and solar power plants. Different components of uncertainty have to be considered depending on whether the power plant is already in operation or in the planning phase. The uncertainty related to a wind farm in the planning phase comprises the methodology of the wind potential estimation and the uncertainty of the site specific wind turbine power curve as well as the uncertainty of the wind farm effect calculation. The uncertainty related to a solar power plant in the pre-operational phase comprises the uncertainty of the radiation data base and that of the performance curve. The long-term mean annual energy yield of operational wind farms and solar power plants is estimated on the basis of the actual energy production and it

This article is an abridged version of the AWMF mould guideline "Medical clinical diagnostics of indoor mould exposure" presented in April 2016 by the German Society of Hygiene, Environmental Medicine and Preventive Medicine ( Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin, GHUP ), in collaboration with the above-mentioned scientific medical societies, German and Austrian societies, medical associations and experts. Indoor mould growth is a potential health risk, even if a quantitative and/or causal relationship between the occurrence of individual mould species and health problems has yet to be established. Apart from allergic bronchopulmonary aspergillosis (ABPA) and mould-caused mycoses, only sufficient evidence for an association between moisture/mould damage and the following health effects has been established: allergic respiratory disease, asthma (manifestation, progression and exacerbation), allergic rhinitis, hypersensitivity pneumonitis (extrinsic allergic alveolitis), and increased likelihood of respiratory infections/bronchitis. In this context the sensitizing potential of moulds is obviously low compared to other environmental allergens. Recent studies show a comparatively low sensitizing prevalence of 3-10% in the general population across Europe. Limited or suspected evidence for an association exist with respect to mucous membrane irritation and atopic eczema (manifestation, progression and exacerbation). Inadequate or insufficient evidence for an association exist for chronic obstructive pulmonary disease, acute idiopathic pulmonary hemorrhage in children, rheumatism/arthritis, sarcoidosis and cancer. The risk of infection posed by moulds regularly occurring indoors is low for healthy persons; most species are in risk group 1 and a few in risk group 2 ( Aspergillus fumigatus, A. flavus ) of the German Biological Agents Act ( Biostoffverordnung ). Only moulds that are potentially able to form toxins can be triggers of toxic

The EML4-ALK pathway plays an important role in a significant subset of non-small cell lung cancer patients. Treatment options such as ALK tyrosine kinase inhibitors lead to improved progression free survival and overall survival. These therapeutic options are chosen on the basis of the identification of the underlying genetic signature of the EML-ALK translocation. Efficient and easily accessible testing tools are required to identify eligible patients in a timely fashion. While FISH techniques are commonly used to detect this translocation, the broad implementation of this type of ALK testing into routine diagnostics is not optimal due to technical, structural and financial reasons. Immunohistochemical techniques to screen for EML4-ALK translocations may therefore play an important role in the near future. This consensus paper provides recommendations for the test algorithm and quality of the respective test approaches, which are discussed in the light of the current literature.

fronts that are observed edge-on. The polarization degrees correspond to Mach numbers of >2.2. Polarized emission is also detected in the radio relics in ZwCl 0008+52 and, for the first time, in Abell 1612. The smaller sizes and lower degrees of polarizations of the latter relics indicate a weaker shock and/or an inclination between the relic and the sky plane. Abell 1612 shows a complex X-ray surface brightness distribution, indicating a recent major merger and supporting the classification of the radio emission as a radio relic. In our cluster sample, no wavelength-dependent Faraday depolarization is detected between 4.85 GHz and 8.35 GHz, except for one component of the Toothbrush relic. Faraday depolarization between 1.38 GHz and 8.35 GHz varies with distance from the center of the host cluster 1RXS 06+42, which can be explained by a decrease in electron density and/or in strength of a turbulent (or tangled) magnetic field. Faraday rotation measures show large-scale gradients along the relics, which cannot be explained by variations in the Milky Way foreground. Conclusions: Single-dish telescopes are ideal tools to confirm relic candidates and search for new relic candidates. Measurement of the wavelength-dependent depolarization along the Toothbrush relic shows that the electron density of the intra-cluster medium (ICM) and strength of the tangled magnetic field decrease with distance from the center of the foreground cluster. Large-scale regular fields appear to be present in intergalactic space around galaxy clusters.

, databases, information portals with processed evidence as well as specific journals and finally teaching are appropriate vehicles. One problem is the multitude of information so that knowledge gaps may affect the clinical routine despite actually existing evidence. Generally, it still takes several years until new knowledge is implemented in daily routine. Tasks: The German Society of Oto-Rhino-Laryngology, Head and Neck Surgery (Deutsche Gesellschaft für Hals-, Nasen- und Ohren-Heilkunde, Kopf- und Hals-Chirurgie e.V., DGHNOKHC) and the Professional Association of Otolaryngologists (Deutscher Berufsverband der HNO-Ärzte e.V., BVHNO) have fundamental interest in supporting their members in generating, processing, and providing evidence as well as accompanying knowledge transfer. It encompasses the fields of diagnostics, therapy, and prognosis in the same way as prevention and applies to medicinal products as well as to medical devices or surgical procedures. The base for this is the regular assessment of evidence gaps, also in the area of established procedures, that has to be followed by a prioritization of research questions and the subsequent initiation of clinical research. In addition, large trials verifying therapies and diagnostics, for example in the context of daily conditions after approval, can only be conducted combining all resources in the ENT community. Method, results, and outlook: Together, the executive committees of the DGHNOKHC and the BVHNO founded the German Study Center of Oto-Rhino-Laryngology, Head and Neck Surgery (Deutsches Studienzentrum für Hals-, Nasen- und Ohren-Heilkunde, Kopf- und Hals-Chirurgie, DSZ-HNO). First projects have been initiated, among those a clinical trial on the therapy of sudden hearing loss supported by the BMBF and a survey on evidence gaps in oto-rhino-laryngology. It seems to be both reasonable and feasible to make available methodological expertise via such an infrastructure of a study center for physicians in

his research and we spent an entire week talking physics and having fun from breakfast in the morning until late at night. A symbolic award was instituted for the best presentation at the workshop, dedicated to the memory of Klaus Kinder-Geiger, a sharp and brilliant young theorist who perished in the crash of Swissair Flight 111 on 2 September 1998 off the coast of Nova Scotia. It went to Denesh Molnar from Ohio State University for his outstanding talk on parton coalescence. The organizers wish to extend their gratitude to all participants for the high quality presentations making Hot Quarks 2004 a notable event. We are also very grateful for the superb hospitality of the staff of the Snakedance Inn, in particular Mitch Daniels who worked sheer miracles. Given the success of the first Hot Quarks workshop we decided to organize a second one, possibly even turning Hot Quarks into a series. The next meeting will be held in the late spring of 2006, probably in Italy. We hope it will be as memorable as the first one! Last but not least, we wish to thank all the generous sponsors of the conference: Brookhaven National Laboratory, European Organization for Nuclear Research (CERN), Gesellschaft fA~ 1/4 r Schwerionenforschung (GSI), Institute of Physics Publishing, Los Alamos National Laboratory, National Science Foundation, and Vanderbilt University. We are grateful for their support and are particularly happy that this support came from institutions both in the US and in Europe and from all the main experimental facilities that pursue a prominent heavy-ion program. Their support was essential for the success of a workshop targeting young scientists.
