Sensitivity of the FISH assay is superior to that of cytology and at least equivalent to the BTA Stat test in detecting recurrent transitional cell carcinoma. Its specificity approaches that of cytology. Further testing of its clinical use is warranted.

In adult caged house flies, maintained on a complete diet of powdered whole milk, cane sugar and water, the median longevity, maximal longevity, and percentage that exhibit complete wing retention at death are increased as the number of individuals per cage is correspondingly decreased from 240 to 10 flies per cage. These effects are more marked for the shorter-lived males than for the females. Female longevities at all population densities are more significantly reduced by a restricted diet of sugar and water only. Under conditions of individual confinement, the life expectancy of the female house fly is no greater than that of the male. These results are in agreement with earlier suggestions that increased physical activity including interaction among individuals in a restricted population decreases longevity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
