An Introduction to Parasitic Wasps of Drosophila and the Antiparasite Immune Response Chiyedza Small*1,2, Indira Paddibhatla*1,2, Roma Rajwani1, Shubha Govind1,2 1Biology Department, The City College of New York, CUNY, 2The Graduate Center, The City University of New York Parasitoid (parasitic) wasps constitute a major class of natural enemies of many insects including Drosophila melanogaster. We will introduce the techniques to propagate these parasites in Drosophila spp. and demonstrate how to analyze their effects on immune tissues of Drosophila larvae.
Isolation and Biophysical Study of Fruit Cuticles Subhasish Chatterjee1, Sayantani Sarkar1, Julia Oktawiec1, Zhantong Mao1, Olivia Niitsoo2, Ruth E. Stark1 1Department of Chemistry, City College of New York, City University of New York Graduate Center and Institute for Macromolecular Assemblies, 2Department of Chemical Engineering, City College of New York Aerial plant organs are protected by the cuticle, a supramolecular biopolyester-wax assembly. We present protocols to monitor selective removal of epi- and intracuticular waxes from tomato fruit cuticles on molecular and micro scales by solid-state NMR and atomic force microscopy, respectively, and to assess the cross-linking capacity of engineered cuticular biopolyesters.
Electrode Positioning and Montage in Transcranial Direct Current Stimulation Alexandre F. DaSilva1, Magdalena Sarah Volz2,3, Marom Bikson4, Felipe Fregni2 1Headache & Orofacial Pain Effort (H.O.P.E.), Biologic & Material Sciences, School of Dentistry, University of Michigan, 2Laboratory of Neuromodulation, Department of Physical Medicine & Rehabilitation, Spaulding Rehabilitation Hospital and Massachusetts General Hospital, Harvard Medical School, 3Charité, University Medicine Berlin, 4Department of Biomedical Engineering, The City College of New York Transcranial direct current stimulation (tDCS) is an established technique to modulate cortical excitability1,2. It has been used as an investigative tool in neuroscience due to its effects on cortical plasticity, easy operation, and safe profile. One area that tDCS has been showing encouraging results is pain alleviation 3-5.
