Cell Block Preparation from Cytology Specimen with Predominance of Individually Scattered Cells

¹Department of Pathology, University of Wisconsin - Milwaukee

Shidham's method for preparation of cell blocks with AV-marker from cytology specimens containing individually scattered cells and small cell groups.

Preparation and Using Phantom Lesions to Practice Fine Needle Aspiration Biopsies

Vinod B. Shidham¹, George M. Varsegi¹, Krista D'Amore¹, Anjani Shidham²

¹Department of Pathology, University of Wisconsin - Milwaukee, ²BioInnovation LLC

Practicing of fine needle aspiration biopsies (FNAB) by trainees is relatively challenging, due to the lack of an easily available, appropriate lesion. Preparation of an AV phantom lesion for practicing the FNAB procedure and mastering proficiency is relatively easy.

Fat pad aspiration is a preferred, minimally invasive, and low cost approach as compared to other methods to detect amyloid for diagnosis of systemic amyloidosis. This video article demonstrates a procedural outline for performing fat pad aspiration with appropriate processing of the specimen for the optimal diagnostic outcome.

In vivo Quantification of G Protein Coupled Receptor Interactions using Spectrally Resolved Two-photon Microscopy

Michael Stoneman¹, Deo Singh¹, Valerica Raicu^1,2

¹Department of Physics, University of Wisconsin - Milwaukee, ²Department of Biological Sciences, University of Wisconsin - Milwaukee

By employing a spectrally resolved two-photon microscopy imaging system, pixel-level maps of Förster Resonance Energy Transfer (FRET) efficiencies are obtained for cells expressing membrane receptors hypothesized to form homo-oligomeric complexes. From the FRET efficiency maps, we are able to estimate stoichiometric information about the oligomer complex under study.
