Loss of peritoneal integrity provides a new paradigm to understand and treat chronic pelvic pain in women with mild forms of endometriosis and can be easily detected using intraoperative instillation of dye at the time of laparoscopy.

In this protocol we show how to condition harnessed honey bees to tactile stimuli and introduce a 2D motion capture technique for analyzing the kinematics of fine-scale antennal sampling pattern.

We describe a technique to extracellularly record and stimulate from nerves, muscles, and individual identified neurons in vitro while eliciting and observing different types of feeding behaviors in the feeding apparatus of Aplysia.
Generation and Recovery of β-cell Spheroids From Step-growth PEG-peptide Hydrogels
Asad Raza, Chien-Chi Lin
Department of Biomedical Engineering, Purdue School of Engineering and Technology, Indiana University - Purdue University at Indianapolis
The following protocol provides techniques for encapsulating pancreatic β-cells in step-growth PEG-peptide hydrogels formed by thiol-ene photo-click reactions. This material platform not only offers a cytocompatible microenvironment for cell encapsulation, but also permits user-controlled rapid recovery of cell structures formed within the hydrogels.
Chromosome Replicating Timing Combined with Fluorescent In situ Hybridization
Leslie Smith, Mathew Thayer
Department of Biochemistry and Molecular Biology, Knight Cancer Institute, Oregon Health & Science University
A quantitative method for the analysis of chromosome replication timing is described. The method utilizes BrdU incorporation in combination with fluorescent in situ hybridization (FISH) to assess replication timing of mammalian chromosomes. This technique allows for the direct comparison of rearranged and un-rearranged chromosomes within the same cell.
The Insect Galleria mellonella as a Powerful Infection Model to Investigate Bacterial Pathogenesis
Nalini Ramarao, Christina Nielsen-Leroux, Didier Lereclus
INRA, Micalis UMR1319, France
Oral and intra haemocolic infection of larvae of the greater wax moth Galleria mellonella is described. This insect can be used to study virulence factors of entomopathogenic as well as mammalian opportunistic bacteria. Rearing of the insects, methods of infection and examples of in vivo analysis are described.
