We note that there is heterogeneity in behaviour between individuals and within individuals. By ‘heterogeneity between individuals’ we mean that people are different, in terms of both their preference functionals and their parameters for these functionals. By ‘heterogen...

Extracts from Hypericum perforatum (St. John’s wort; Clusiaceae) are widely used for the treatment of mild to moderate depression. Four classes of constituents – hyperforins, hypericins, flavonoids, and xanthones – appear to contribute to the antidepressant activity. Interestingly, all four classes of secondary metabolites involve polyketide derivatives. Key reactions of their biosyntheses are ...
