Analysis of <em>Plasmodium falciparum</em> var genes expressed in children from Papua New Guinea (Publications)
BACKGROUND: The variable antigen P. falciparum erythrocyte membrane protein-1 (PfEMP1) is a major virulence factor in malaria. A large number of var genes encode PfEMP1, and we hypothesized that a res
Effect of mutation and genetic background on drug resistance in <em>Mycobacterium tuberculosis</em> (Publications)

Didemnidines A and B, indole spermidine alkaloids from the New Zealand ascidian <em>Didemnum</em> sp (Publications)
Two new indole spermidine alkaloids, didemnidines A (1) and B (2), have been isolated from the New Zealand ascidian Didemnum sp. The structures of the metabolites, determined by analysis of 2D NMR spe
