Profiling the expression levels of genes or proteins in tissues comprising two or more cell types is commonplace in biological sciences. Such analyses present particular challenges, however, for example a potential shift in cellular composition, or 'cellularity', between specimens. That is, does an observed change in expression level represent what occurs within individual cells, or does it rep...

We appreciate Dr. Drewinko’s clarification of the term “aspirate” as used in our report. Although the technique of the aspirate smear preparations was described in Materials and Methods, the more precise term “aspirate smear preparation” would be more appropriate. The experience by others as described by Dr. Drewinko has in general demonstrated the superiority of cellularity determination using...

For topological spaces X and Y, let Qp(X,Y) be the space of all quasicontinuous functions from to Y with topology pointwise convergence. In this paper, we study cardinal invariants such as cellularity, character, weight, density, pseudocharacter spread Qp(X,Y). We also discuss properties restriction induced maps related
