We recently identified those hyper-saline environments as additional sources for a multitude of volatile halogenated organohalogens (VOX). These compounds can affect the ozone layer of the stratosphere and play a key role in the production of aerosols. A remote sensing based analysis was performed in the Southern Aral Sea basin, providing information of major soil types as well as their extent and spatial and temporal evolution. VOX production has been determined in dry and moist soil samples after 24 h. Several C1- and C2 organohalogens have been found in hyper-saline topsoil profiles, including CH3Cl, CH3Br, CHBr3 and CHCl3. The range of organohalogens also includes trans-1,2-dichloroethene (DCE), which is reported here to be produced naturally for the first time. Using MODIS time series and supervised image classification a daily production rate for DCE has been calculated for the 15 000 km\(^2\) ranging research area in the southern Aralkum. The applied laboratory setup simulates a short-term change in climatic conditions, starting from dried-out saline soil that is instantly humidified during rain events or flooding. It describes the general VOX production potential, but allows only for a rough estimation of resulting emission loads. VOX emissions are expected to increase in the future since the area of salt affected soils is expanding due to the regressing Aral Sea. Opportunities, limits and requirements of satellite based rapid change detection and salt classification are discussed.}, language = {en} } @article{StoelzelMohrKrameretal.2016, author = {St{\"o}lzel, F. and Mohr, B. and Kramer, M. and Oelschl{\"a}gel, U. and Bochtler, T. and Berdel, W.

The European Leukemia Net classification and the UK Medical Research Council recommendation provide prognostic categories that differ in the definition of unbalanced aberrations as well as the number of single aberrations. The aim of this study on 3526 AML patients was to redefine and validate a cutoff for karyotype complexity in AML with regard to adverse prognosis. Our study demonstrated that (1) patients with a pure hyperdiploid karyotype have an adverse risk irrespective of the number of chromosomal gains, (2) patients with translocation t(9;11)(p21∼22;q23) have an intermediate risk independent of the number of additional aberrations, (3) patients with 4 abnormalities have an adverse risk per se and (4) patients with three aberrations in the absence of abnormalities of strong influence (hyperdiploid karyotype, t(9;11)(p21∼22;q23), CBF-AML, unique adverse-risk aberrations) have borderline intermediate/adverse risk with a reduced overall survival compared with patients with a normal karyotype.}, language = {en} } @article{FehskeBerningerAlmetal.2021, author = {Fehske, Kai and Berninger, Markus T. and Alm, Lena and Hoffmann, Reinhard and Zellner, Johannes and K{\"o}sters, Clemens and Barzen, Stefan and Raschke, Michael J. and Izadpanah, Kaywan and Herbst, Elmar and Domnick, Christoph and Sch{\"u}ttrumpf, Jan Philipp and Krause, Matthias}, title = {Aktueller Versorgungsstandard von Patellafrakturen in Deutschland}, series = {Der Unfallchirurg}, volume = {124}, journal = {Der Unfallchirurg}, organization = {Komitee Frakturen der Deutschen Kniegesellschaft (DKG)}, issn = {0177-5537}, doi = {10.1007/s00113-020-00939-8}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-235047}, pages = {832-838}, year = {2021}, abstract = {Hintergrund Die Versorgung von Patellafrakturen ist technisch anspruchsvoll. Auch wenn die radiologischen Ergebnisse zumeist zufriedenstellend sind, deckt sich dies h{\"a}ufig nicht mit der subjektiven Einsch{\"a}tzung der Patienten. Die klassische Versorgung mittels Drahtzuggurtung weist einige Komplikationen auf. Die winkelstabile Plattenosteosynthese hat sich in den letzten Jahren biomechanisch als vorteilhaft erwiesen. Fragestellung Von wem werden Patellafrakturen in Deutschland versorgt? Wie sieht der aktuelle Versorgungsstandard aus? Haben sich „moderne" Osteosyntheseformen durchgesetzt? Was sind die h{\"a}ufigsten Komplikationen? Material und Methoden Die Mitglieder der Deutschen Gesellschaft f{\"u}r Orthop{\"a}die und Unfallchirurgie sowie der Deutschen Kniegesellschaft wurden aufgefordert, an einer Onlinebefragung teilzunehmen. Ergebnisse Insgesamt wurden 511 komplett ausgef{\"u}llte Fragebogen ausgewertet. Die Befragten sind zum gr{\"o}ßten Teil auf Unfallchirurgie spezialisiert (51,5 \%) und verf{\"u}gen {\"u}ber langj{\"a}hrige Berufserfahrung in Traumazentren. Die H{\"a}lfte der Operateure versorgt ≤5 Patellafrakturen j{\"a}hrlich. In knapp 40 \% der F{\"a}lle wird die pr{\"a}operative Bildgebung um eine Computertomographie erg{\"a}nzt. Die klassische Zuggurtung ist noch die bevorzugte Osteosyntheseform bei allen Frakturtypen (Querfraktur 52 \%, Mehrfragmentfrakturen 40 \%). Bei Mehrfragmentfrakturen entscheiden sich 30 \% der Operateure f{\"u}r eine winkelstabile Plattenosteosynthese. Bei Beteiligung des kaudalen Pols dient als zus{\"a}tzliche Sicherung die McLaughlin-Schlinge (60 \%). Diskussion Der Versorgungsstandard von Patellafrakturen in Deutschland entspricht weitgehend der aktualisierten S2e-Leitlinie. Nach wie vor wird die klassische Zuggurtungsosteosynthese als Verfahren der Wahl genutzt. Weitere klinische (Langzeit‑)Studien werden ben{\"o}tigt, um die Vorteile der winkelstabilen Plattenosteosynthese zu verifizieren.}, language = {de} }
