Yost3 1Department of Physics, State University of New York-Oswego, 2Department of Chemistry, University of Nebraska-Lincoln, 3Department of Physics, University of Nebraska-Lincoln, 4Department of Chemistry, Doane University, 5Physikalisches Institut, Universität Bayreuth A protocol for synthesizing inorganic-lead-halide hybrid perovskite quantum dot inks for inkjet printing and the protocol for preparing and printing the quantum dot inks in an inkjet printer with post characterization techniques are presented.
Assessment of Dictyostelium discoideum Response to Acute Mechanical Stimulation Yulia Artemenko1, Peter N. Devreotes2 1Department of Biological Sciences, SUNY Oswego, 2Department of Cell Biology, Johns Hopkins University School of Medicine Here we describe methods for assessing cellular response to acute mechanical stimulation. In the microscopy-based assay, we examine localization of fluorescently-labeled biosensors following brief stimulation with shear flow. We also test activation of various proteins of interest in response to acute mechanical stimulation biochemically.
Rearing the Fruit Fly Drosophila melanogaster Under Axenic and Gnotobiotic Conditions Melinda L. Koyle1, Madeline Veloz1, Alec M. Judd1, Adam C.-N. Wong2,4, Peter D. Newell2,5, Angela E. Douglas2,3, John M. Chaston1,2 1Department of Plant and Wildlife Sciences, Brigham Young University, 2Department of Entomology, Cornell University, 3Department of Molecular Biology and Genetics, Cornell University, 4Division of Infectious Diseases, Boston Children's Hospital, Harvard Medical School, 5Biological Sciences, SUNY Oswego A method for rearing Drosophila melanogaster under axenic and gnotobiotic conditions is presented. Fly embryos are dechorionated in sodium hypochlorite, transferred aseptically to sterile diet, and reared in closed containers. Inoculating diet and embryos with bacteria leads to gnotobiotic associations, and bacterial presence is confirmed by plating whole-body Drosophila homogenates.
