In situ visualization of microbial communities within their natural habitats provides a powerful approach to explore complex interactions between microorganisms and their macroscopic hosts. Specifically, the application of fluorescence in situ hybridization (FISH) to simultaneously identify and visualize diverse microbial taxa associated with coral hosts, including symbiotic algae (Symbiodinium...

PURPOSE Although cytologic examination of CSF is the primary method for the evaluation of response to therapy for leptomeningeal metastases (LMMs), the procedure's sensitivity decreases throughout the course of protracted therapy. We studied whether this response could be monitored more accurately through the detection of numerical chromosomal aberrations by interphase cytogenetics, using fluor...

Most current approaches for quantification of RNA species in their natural spatial contexts in single cells are limited by a small number of parallel analyses. Here we report a strategy to dramatically increase the multiplexing capacity for RNA analysis in single cells in situ. In this method, transcripts are detected by fluorescence in situ hybridization (FISH). After imaging and data storage,...

Preimplantation genetic diagnosis (PGD) is a novel approach for the prevention of genetic disorders in couples at risk of having offspring with genetic disease. Although the original idea dates back to early 1960s when sexing of rabbit blastocysts was attempted, the first clinical application of PGD was reported about three decades later, describing the use of PCR for sexing embryos from couple...

Chromogenic in situ hybridization (CISH) has shown the potential to replace fluorescence in situ hybridization (FISH) to determine HER2 gene status. To validate the reliability of CISH, we used 226 consecutive breast carcinomas from 2 institutions and tested CISH and FISH on the same tumor set simultaneously at different test sites. Besides manufacturers' scoring criteria, the new American Soci...
