Mike Hasenberg1, Anja K&#246;hler1, Susanne Bonifatius1, Andreas Jeron2, Matthias Gunzer1 1Institute for Molecular and Clinical Immunology, Otto-von-Guericke University Magdeburg, 2Department of Immunoregulation, Helmholtz Center for Infection Research
We show, how to use 2-photon microscopy for the observation of the dynamics of neutrophil granulocytes in infected lungs while they phagocytose pathogens or produce neutrophil extracellular traps (NETs)

Rital B. Bhavsar1,*, Kenta Nakamura1,*, Panagiotis A. Tsonis1, 2 1Department of Biology, University of Dayton, 2Center for Tissue Regeneration and Engineering, University of Dayton * These authors contributed equally
In newt, the lens regenerates always from the dorsal iris by transdifferentiation of the iris pigmented epithelial cells (IPEs). Here we describe a procedure to culture dorsal and ventral newt IPE cells and their implantation to the newt eye. The implanted cells are then studied by tissue sectioning and immunohistochemistry.

Aaron T. Haselton1, Yih-Woei C. Fridell2 1Department of Biology, State University of New York, 2Allied Health Sciences, University of Connecticut
Conserved insulin signaling pathways found in the fruit fly Drosophila melanogaster make this organism a potential tool for modeling metabolic disorders including type II diabetes. To this end, it is critical to establish physiological assays to effectively measure systemic insulin action in peripheral glucose disposal in the adult fly.

Jing Chen, Scott Grieshaber, Clayton E. Mathews Departments of Pathology, Immunology and Laboratory Medicine, College of Medicine, University of Florida
Cell-mediated lymphocytotoxicity (CML) assays can be used to test autoreactive responses and study mechanisms of cell death in vitro. However, using live-cell confocal microscopic imaging techniques with fluorescent dyes, the type and kinetics of cell death as well as the pathways utilized can be studied in greater detail.

David W. Haley, Adekemi J. Akano, Joanna Dudek Department of Psychology, University Toronto Scarborough
Dense array electroencephalography is being used increasingly to study social cognitive functions in infants and adults. Here we present an established methodology that represents a significant improvement on conventional methodologies for studying EEG in infants and adults.

We present a novel approach to quantify nanoparticle localization in the vasculature of human xenografted tumors using dynamic, real-time intravital imaging in an avian embryo model.

Philip M. Armstrong, Theodore G. Andreadis, Shannon L. Finan, John J. Shepard, Michael C. Thomas The Connecticut Agricultural Experiment Station, Center for Vector Biology and Zoonotic Diseases, Department of Environmental Sciences
We describe a method to process and screen field-collected mosquitoes for a diversity of viruses by Vero cell culture assay. By employing this technique, we have detected 9 different viruses from 4 taxonomic families in mosquitoes collected in Connecticut.

Michael Junkin1, Siu Ling Leung1, Yongliang Yang1, Yi Lu1, Justin Volmering1, Pak Kin Wong1, 2 1Aerospace and Mechanical Engineering, University of Arizona , 2Biomedical Engineering IDP and BIO5 Institute, University of Arizona 
A versatile plasma lithography technique has been developed to generate stable surface patterns for guiding cellular attachment. This technique can be applied to create cell networks including those that mimic natural tissues and has been used for studying several, distinct cell types.
