“In the 1930s and 1940s, Curt Richter and others demonstrated that rats deficient in particular nutrients would select foods that were rich in these nutrients. Rozin was attracted to this problem in the early 1960s because the phenomenon was simple, easy to obtain, and biologically significant. Furthermore, it seemed unlikely that all specific hungers could be explained either as innate mechani...

UNLABELLED We have devised a novel analysis approach, percentile analysis for differential gene expression (PADGE), for identifying genes differentially expressed between two groups of heterogeneous samples. PADGE was designed to compare expression profiles of sample subgroups at a series of percentile cutoffs and to examine the trend of relative expression between sample groups as expression l...
