โœฆ Synopsis


Analyses of plant use in Amazonia by three species of nonhuman primates reveal a common trend: more primitive plant species are used as food. An identical situation prevails for three indigenous human societies which additionally selected more recently evolved plant species as medicine. One hypothesis to explain the observations is related to the presence of toxic constituents in the more advanced species, in contrast to astringent polyphenols in the more primitive ones. Thus a certain degree of astringency might indicate absence of harmful chemicals, and even stimulate ingestion.

[(18)F]Fallypride is a highly selective, high-affinity dopamine D-2 receptor ligand. The high affinity, K(D) = 30 pM, makes it a suitable candidate for visualizing both striatal and extrastriatal binding in the brain. In this work, dynamic PET studies of two macaque monkeys were acquired along with
