T1  - Geisteswissenschaft und Geografische Informationssysteme (GIS): Erstellung von Kartierungen mit kommerzieller und Open Source Software im Vergleich
T1  - Digital Humanities and Geographic Information Systems (GIS): Making maps with commercial and open source software
N2  - Der Einsatz von Geographischen Informationssystemen (GIS) bietet auch für die Geisteswissenschaften zahlreiche Ansätze zur Generierung von neuem Wissen. Die GIS-Software ist jedoch unterschiedlich geeignet für geisteswissenschaftliche Fragestellungen. Getestet wurden daher zwei kommerzielle und vier Open Source GIS-Programme: MapInfo, ArcGIS, Quantum GIS, gvSIG, DIVA-GIS und SAGA. MapInfo zeichnet sich besonders für GIS-Anfänger durch seine große Benutzerfreundlichkeit aus. Jedoch sind die Anschaffungskosten recht hoch. ArcGIS weist den größten Nutzungsumfang auf, wobei jedoch keine oder kaum eine „intuitive“ Nutzung möglich ist. Zudem sind die laufenden Kosten durch aufwändige Abo-Lizenzverträge besonders hoch. Quantum GIS ist eine freie Software, die benutzerfreundlich ist und auch Anfängern einen leichten Einstieg ermöglicht. Hunderte Erweiterungen machen Quantum GIS sehr leistungsstark und universal einsetzbar. gvSIG ist nicht ganz leicht zu bedienen, da zudem die Dokumentation nur fragmentarisch vorliegt. Der große Funktionsumfang macht es jedoch zu einem vollwertigen GIS, wenn auch manch ergänzende Funktion fehlt. DIVA-GIS ermöglicht einen schnellen Einstieg durch seine gute Dokumentation. Man gelangt jedoch recht bald an die Grenzen des Nutzungsumfangs durch die eingeschränkte Funktionalität. SAGA hingegen erfüllte alle hier gestellten Anforderungen, sodass es, trotz der geringeren Anzahl von Erweiterungen, zusammen mit Quantum GIS als Open Source eine echte Alternative zu kommerziellen GIS-Programmen darstellt.
N2  - The use of Geographic Information Systems (GIS) is also in the Humanities an interesting method to analyze questions of space and time. For creating new results, we need to search reputed GIS software for our regular use. Within this article we tested two commercial and four open source GIS programs: MapInfo, ArcGIS, Quantum GIS, gvSIG, DIVA-GIS and SAGA. ArcGIS has the greatest functionality. But it is very expensive and not easy to use. MapInfo is particularly distinguished for GIS-beginners due to its large usability. However, the cost is quite high. Quantum GIS is a free software that is user friendly, and even for beginners easy to get started. gvSIG is not very easy to use and some ancillary functions are missing. DIVA-GIS provides a quick start by its good documentation. But the functionality is limited pretty soon. Many functions make SAGA to a full-fledged GIS, despite the lower number of enhancements. Hundreds extensions make Quantum GIS very powerful and versatile. Altogether for the Humanities the open source Quantum GIS represents a viable alternative to expensive commercial GIS software.

T1  - Effect of ABCG2, OCT1, and ABCB1 (MDR1) Gene Expression on Treatment-Free Remission in a EURO-SKI Subtrial
JF  - Clinical Lymphoma, Myeloma & Leukemia
N2  - Within the EURO-SKI trial, 132 chronic phase CML patients discontinued imatinib treatment. RNA was isolated from peripheral blood in order to analyze the expression of MDR1, ABCG2 and OCT1. ABCG2 was predictive for treatment-free remission in Cox regression analysis. High transcript levels of the ABCG2 efflux transporter (>4.5 parts per thousand) were associated with a twofold higher risk of relapse. Introduction: Tyrosine kinase inhibitors (TKIs) can safely be discontinued in chronic myeloid leukemia (CML) patients with sustained deep molecular response. ABCG2 (breast cancer resistance protein), OCT1 (organic cation transporter 1), and ABCB1 (multidrug resistance protein 1) gene products are known to play a crucial role in acquired pharmacogenetic TKI resistance. Their influence on treatment-free remission (TFR) has not yet been investigated. Materials and Methods: RNA was isolated on the last day of TKI intake from peripheral blood leukocytes of 132 chronic phase CML patients who discontinued TKI treatment within the European Stop Tyrosine Kinase Inhibitor Study trial. Plasmid standards were designed including subgenic inserts of OCT1, ABCG2, and ABCB1 together with GUSB as reference gene. For expression analyses, quantitative real-time polymerase chain reaction was used. Multiple Cox regression analysis was performed. In addition, gene expression cutoffs for patient risk stratification were investigated. Results: The TFR rate of 132 patients, 12 months after TKI discontinuation, was 54% (95% confidence interval [CI], 46%-62%). ABCG2 expression (parts per thousand) was retained as the only significant variable (P=.02; hazard ratio, 1.04; 95% CI, 1.01-1.07) in multiple Cox regression analysis. Only for the ABCG2 efflux transporter, a significant cutoff was found (P=.04). Patients with an ABCG2/GUSB transcript level >4.5 parts per thousand (n=93) showed a 12-month TFR rate of 47% (95% CI, 37%-57%), whereas patients with low ABCG2 expression (<= 4.5 parts per thousand; n=39) had a 12-month TFR rate of 72% (95% CI, 55%-82%). Conclusion: In this study, we investigated the effect of pharmacogenetics in the context of a CML treatment discontinuation trial. The transcript levels of the efflux transporter ABCG2 predicted TFR after TKI discontinuation. (C) 2018 The Authors. Published by Elsevier Inc.
