- ItemWerbung für den Apothekenbetrieb in örtlichen Festschriften(Stuttgart : Deutscher Apotheker Verlag, 2004-09) Diebold, Steffen M.Der vorliegende Beitrag widmet sich einem Aspekt der Sozial- und Kulturgeschichte, der bislang weder von der volkskundlichen noch von der sozialwissenschaftlichen Forschung aufgegriffen worden ist. Am Beispiel von Vereinsfestschriften des 20. Jahrhunderts wird demonstriert, wie sich Apotheken außerhalb von Fachkreisen der Öffentlichkeit präsentierten und dadurch für ihr Unternehmen warben. Über den alltagshistorischen Aspekt hinaus vermitteln die Annoncen der Festschriften en passant damit auch einen Einblick in wirtschaftliche, gesellschaftliche oder soziale Verhältnisse im Deutschland der Nachkriegszeit.
- ItemProdukthaftung in der Apotheke(Stuttgart : Deutscher Apotheker Verlag, 2005) Diebold, Steffen M.Stellt ein Apotheker Arzneimittel, Medizinprodukte oder andere apothekenübliche Waren (z.B. Kosmetika oder Mixturen nach Angaben von Heilpraktikern, Homöopathen oder Anthroposophen) in seiner Offizin selbst her, so haftet er (grundsätzlich) einem dadurch ggf. geschädigten Kunden (auch) nach den Vorschriften des Produkthaftungsgesetzes. Diese Haftung besteht unabhängig vom eigenen Verschulden. Sie greift auch bei der Einfuhr von Arzneimitteln aus Staaten, die nicht zum Europäischen Wirtschaftsraum gehören, sowie bei Import und Abgabe von aus Drittländern eingeführten und im Geltungsbereich des Arzneimittelgesetzes (AMG) nicht zugelassenen Fertigarzneimitteln nach § 73 (3) AMG.

- ItemSuccessful downstream application of the Paxgene Blood RNA system from small blood samples in paediatric patients for quantitative PCR analysis(London : BioMed Central, 2007) Carrol, Enitan D.; Salway, Fiona; Pepper, Stuart D.; Saunders, Emma; Mankhambo, Limangeni A.; Ollier, William E.; Hart, C. Anthony; Day, PhillipBackground: The challenge of gene expression studies is to reliably quantify levels of transcripts, but this is hindered by a number of factors including sample availability, handling and storage. The PAXgene™ Blood RNA System includes a stabilizing additive in a plastic evacuated tube, but requires 2.5 mL blood, which makes routine implementation impractical for paediatric use. The aim of this study was to modify the PAXgene™ Blood RNA System kit protocol for application to small, sick chidren, without compromising RNA integrity, and subsequently to perform quantitative analysis of ICAM and interleukin-6 gene expression. Aliquots of 0.86 mL PAXgene™ reagent were put into microtubes and 0.3 mL whole blood added to maintain the same recommended proportions as in the PAXgene™ evacuated tube system. RNA quality was assessed using the Agilent BioAnalyser 2100 and an in-house TaqMan™ assay which measures GAPDH transcript integrity by determining 3' to 5' ratios. qPCR analysis was performed on an additional panel of 7 housekeeping genes. Three reference genes (HPRT1, YWHAZ and GAPDH) were identified using the GeNORM algorithm, which were subsequently used to normalising target gene expression levels. ICAM-1 and IL-6 gene expression were measured in 87 Malawian children with invasive pneumococcal disease. Results: Total RNA yield was between 1,114 and 2,950 ng and the BioAnalyser 2100 demonstrated discernible 18s and 28s bands. The cycle threshold values obtained for the seven housekeeping genes were between 15 and 30 and showed good consistency. Median relative ICAM and IL-6 gene expression were significantly reduced in non-survivors compared to survivors (ICAM: 3.56 vs 4.41, p = 0.04, and IL-6: 2.16 vs 6.73, p = 0.02). Conclusion: We have successfully modified the PAXgene™ blood collection system for use in small children and demonstrated preservation of RNA integrity and successful quantitative real-time PCR analysis.

- ItemOxaliplatin-DNA adduct formation in white blood cells of cancer patients(London : Nature Publishing Group, 2008) Pieck, A.C.; Drescher, A.; Wiesmann, K.G.; Messerschmidt, J.; Weber, G.; Strumberg, D.; Hilger, R.A.; Scheulen, M.E.; Jaehde, U.In this study, we investigated the kinetics of oxaliplatin-DNA adduct formation in white blood cells of cancer patients in relation to efficacy as well as oxaliplatin-associated neurotoxicity. Thirty-seven patients with various solid tumours received 130 mg m−2 oxaliplatin as a 2-h infusion. Oxaliplatin-DNA adduct levels were measured in the first cycle using adsorptive stripping voltammetry. Platinum concentrations were measured in ultrafiltrate and plasma using a validated flameless atomic absorption spectrometry method. DNA adduct levels showed a characteristic time course, but were not correlated to platinum pharmacokinetics and varied considerably among individuals. In patients showing tumour response, adduct levels after 24 and 48 h were significantly higher than in nonresponders. Oxaliplatin-induced neurotoxicity was more pronounced but was not significantly different in patients with high adduct levels. The potential of oxaliplatin-DNA adduct measurements as pharmacodynamic end point should be further investigated in future trials.
- ItemAlterations in Event Related Potentials (ERP) associated with tinnitus distress and attention(Dordrecht [u.a.] : Springer Science + Business Media B.V, 2008) Delb, W.; Strauss, D.J.; Low, Y.F.; Seidler, H.; Rheinschmitt, A.; Wobrock, T.; D'Amelio, R.Tinnitus related distress corresponds to different degrees of attention paid to the tinnitus. Shifting attention to a signal other than the tinnitus is therefore particularly difficult for patients with high tinnitus related distress. As attention effects on Event Related Potentials (ERP) have been shown this should be reflected in ERP measurements (N100, phase locking). In order to prove this hypothesis single sweep ERP recordings were obtained in 41 tinnitus patients as well as 10 control subjects during a period of time when attention was shifted to a tone (attended) and during a second phase (unattended) when they did not focus attention to the tone. Whereas tinnitus patients with low distress showed a significant reduction in both N100 amplitude and phase locking when comparing the attended and unattended measurement condition a group of patients with high tinnitus related distress did not show such ERP alterations. Using single sweep ERP measurements the results of our study show, that attention in high tinnitus related distress patients is captured by their tinnitus significantly more than in low distress patients. Furthermore our results provide the basis for future neurofeedback based tinnitus therapies aiming at maximizing the ability to shift attention away from the tinnitus. © 2008 The Author(s).

- ItemGain of a 500-fold sensitivity on an intravital MR Contrast Agent based on an endohedral Gadolinium-Cluster-Fullerene-Conjugate: A new chance in cancer diagnostics(Sydney : Ivyspring, 2010) Braun, Klaus; Dunsch, Lothar; Pipkorn, Ruediger; Bock, Michael; Baeuerle, Tobias; Yang, Shangfeng; Waldeck, Waldemar; Wiessler, ManfredAmong the applications of fullerene technology in health sciences the expanding field of magnetic resonance imaging (MRI) of molecular processes is most challenging. Here we present the synthesis and application of a GdxSc3-xN@C80-BioShuttle-conjugate referred to as Gd-cluster@-BioShuttle, which features high proton relaxation and, in comparison to the commonly used contrast agents, high signal enhancement at very low Gd concentrations. This modularly designed contrast agent represents a new tool for improved monitoring and evaluation of interventions at the gene transcription level. Also, a widespread monitoring to track individual cells is possible, as well as sensing of microenvironments. Furthermore, BioShuttle can also deliver constructs for transfection or active pharmaceutical ingredients, and scaffolding for incorporation with the host's body. Using the Gd-cluster@-BioShuttle as MRI contrast agent allows an improved evaluation of radio- or chemotherapy treated tissues.
- ItemRole of thioredoxin reductase 1 and thioredoxin interacting protein in prognosis of breast cancer(London : BioMed Central, 2010) Cadenas, Cristina; Franckenstein, Dennis; Schmidt, Marcus; Gehrmann, Mathias; Hermes, Matthias; Geppert, Bettina; Schormann, Wiebke; Maccoux, Lindsey J.; Schug, Markus; Schumann, Anika; Wilhelm, Christian; Freis, Evgenia; Ickstadt, Katja; Rahnenführer, Jörg; Baumbach, Jörg I.; Sickmann, Albert; Hengstler, Jan G.Introduction: The purpose of this work was to study the prognostic influence in breast cancer of thioredoxin reductase 1 (TXNRD1) and thioredoxin interacting protein (TXNIP), key players in oxidative stress control that are currently evaluated as possible therapeutic targets. Methods: Analysis of the association of TXNRD1 and TXNIP RNA expression with the metastasis-free interval (MFI) was performed in 788 patients with node-negative breast cancer, consisting of three individual cohorts (Mainz, Rotterdam and Transbig). Correlation with metagenes and conventional clinical parameters (age, pT stage, grading, hormone and ERBB2 status) was explored. MCF-7 cells with a doxycycline-inducible expression of an oncogenic ERBB2 were used to investigate the influence of ERBB2 on TXNRD1 and TXNIP transcription. Results: TXNRD1 was associated with worse MFI in the combined cohort (hazard ratio = 1.955; P < 0.001) as well as in all three individual cohorts. In contrast, TXNIP was associated with better prognosis (hazard ratio = 0.642; P < 0.001) and similar results were obtained in all three subcohorts. Interestingly, patients with ERBB2-status-positive tumors expressed higher levels of TXNRD1. Induction of ERBB2 in MCF-7 cells caused not only an immediate increase in TXNRD1 but also a strong decrease in TXNIP. A subsequent upregulation of TXNIP as cells undergo senescence was accompanied by a strong increase in levels of reactive oxygen species. Conclusions: TXNRD1 and TXNIP are associated with prognosis in breast cancer, and ERBB2 seems to be one of the factors shifting balances of both factors of the redox control system in a prognostic unfavorable manner.

- ItemIdentification of Eps15 as antigen recognized by the monoclonal antibodies aa2 and ab52 of the wuerzburg hybridoma library against Drosophila brain(San Francisco, CA : Public Library of Science, 2011) Halder, Partho; Chen, Yi-chun; Brauckhoff, Janine; Hofbauer, Alois; Dabauvalle, Marie-Christine; Lewandrowski, Urs; Winkler, Christiane; Sickmann, Albert; Buchner, ErichThe Wuerzburg Hybridoma Library against the Drosophila brain represents a collection of around 200 monoclonal antibodies that bind to specific structures in the Drosophila brain. Here we describe the immunohistochemical staining patterns, the Western blot signals of one- and two-dimensional electrophoretic separation, and the mass spectrometric characterization of the target protein candidates recognized by the monoclonal antibodies aa2 and ab52 from the library. Analysis of a mutant of a candidate gene identified the Drosophila homolog of the Epidermal growth factor receptor Pathway Substrate clone 15 (Eps15) as the antigen for these two antibodies.
