OBJECTIVES To determine the outcomes for patients with nondiagnostic fluorescence in situ hybridization (FISH) (ie, < 4 gains of chromosomes 3, 7, or 17 in < or = 3 cells). FISH detects urothelial carcinoma and is especially beneficial in patients with negative or atypical urine cytology findings. A positive result is defined as a gain of > or = 2(More)
Tools capable of imaging and perturbing mechanical signaling pathways with fine spatiotemporal resolution have been elusive, despite their importance in diverse cellular processes. The challenge in developing a mechanogenetic toolkit (i.e., selective and quantitative activation of genetically encoded mechanoreceptors) stems from the fact that many(More)
