Investigating the Detrimental Effects of Low Pressure Plasma Sterilization on the Survival of Bacillus subtilis Spores Using Live Cell Microscopy Felix M. Fuchs1, Marina Raguse1,2,3, Marcel Fiebrandt2, Kazimierz Madela4, Peter Awakowicz2, Michael Laue4, Katharina Stapelmann3, Ralf Moeller1 1Department of Radiation Biology, Institute of Aerospace Medicine, Space Microbiology Research Group, German Aerospace Center (DLR e.V.), 2Institute of Electrical Engineering and Plasma Technology, Faculty of Electrical Engineering and Information Technology, Ruhr-University Bochum, 3Institute of Electrical Engineering and Plasma Technology, Faculty of Electrical Engineering and Information Technology, Biomedical Applications of Plasma Technology, Ruhr-University Bochum, 4Advanced Light and Electron Microscopy (ZBS 4), Robert Koch Institute This protocol illustrates the important consecutive steps required to assess the relevance of monitoring vitality parameter and DNA repair processes in reviving Bacillus subtilis spores after treatment with low pressure plasma by tracking fluorescence-labelled DNA repair proteins via time-resolved confocal microscopy and scanning electron microscopy.
Simple Methods for the Preparation of Non-noble Metal Bulk-electrodes for Electrocatalytic Applications Kai junge Puring1,2, Stefan Piontek1, Mathias Smialkowski1, Jens Burfeind2, Stefan Kaluza2, Christian Doetsch2, Ulf-Peter Apfel1 1Faculty of Chemistry and Biochemistry, Inorganic Chemistry I, Ruhr-University Bochum, 2Fraunhofer Institute for Environmental, Safety, and Energy Technology, UMSICHT A facile preparation method of electrodes using the bulk material Fe4.5Ni4.5S8 is presented. This method provides an alternative technique to conventional electrode fabrication and describes prerequisites for unconventional electrode materials including a straightforward electrocatalytic testing method.
Lectin-based Isolation and Culture of Mouse Embryonic Motoneurons Rebecca Conrad1, Sibylle Jablonka2, Teresa Sczepan1, Michael Sendtner2, Stefan Wiese1, Alice Klausmeyer1 1Institute for Cellmorphology and molecular Neurobiology, Group for Cellbiology, Ruhr-University Bochum, 2Institute for Clinical Neurobiology, University of Wuerzburg An alternative way of isolating mouse embryonic motoneurons from the spinal cord is described. The method takes into account the fact that lectin can bind to the low affinity nerve growth factor receptor p75NTR. This lectin-based preplating allows a purification similar to that with a specific antibody against the p75NTR.
