Abietane diterpenoids from <em>Salvia sahendica</em> - antiprotozoal activity and determination of their absolute configurations (Publications)
In a screening of Iranian plants for antiprotozoal activity, an n-hexane extract of the roots of Salvia sahendica potently inhibited the growth of Plasmodium falciparum K1 strain. Subsequent HPLC-base
Development and validation of a clinical decision rule for the diagnosis of influenza (Publications)

Effectiveness of dog rabies vaccination programmes: comparison of owner-charged and free vaccination campaigns (Publications)
We investigated the percentage of dogs that could be vaccinated against rabies by conducting a pilot campaign in N'Djamena, Chad. Owners were charged US$4.13 per dog vaccinated, and 24% of all dogs in
The structure and antimalarial activity of dispiro-1,2,4,5-tetraoxanes derived from (+)-dihydrocarvone (Publications)
An unsaturated dispiro 1,2,4,5-tetraoxane formed by peroxidation of (+)-dihydrocarvone was converted into four structurally diverse derivatives. X-ray crystallographic analysis shows that the structur
Comparative antimalarial activities of six pairs of 1,2,4,5-tetraoxanes (peroxide dimers) and 1,2,4,5,7,8-hexaoxonanes (peroxide trimers) (Publications)
Six tetraoxanes had 50% inhibitory concentrations in the range of 10 to 100 ng/ml against Plasmodium falciparum, whereas the corresponding hexaoxonanes had minimal antimalarial activity. The lack of i
<em>Plasmodium</em> sensitivity to artemisinins: magic bullets hit elusive targets (Publications)
Artemisinins are efficacious antimalarial drugs widely employed as first-line treatment in endemic countries under the form of combined therapies. Different molecular modes of action have been postula
