The only known macromolecules within prions are prion proteins (PrP). The cDNA encoding the hamster prion protein (PrP 27-30) has been cloned and sequenced (Oesch et al., 1985). Using that hamster PrP cDNA, we screened a(More)
The hypothesis that leaf resin ofHymenaea courbaril (Leguminosae) functions as a defence against herbivory was tested in a series of experiments with the generalist herbivore, beet armyworm (Spodoptera exigua Hübn). Pure leaf resin obtained by steam distillation was incorporated into an artificial diet at 0.0%, 0.16%, 0.50%, and 1.60% (dry weight) in one(More)
