Antimalarial pantothenamide metabolites target acetyl-coenzyme A biosynthesis in <em>Plasmodium falciparum</em> (Publications)
enzymes in the sensitivity of the malaria parasites to pantothenamides. These pantothenamide compounds with a new mode of action may have potential as drugs against malaria parasites. [...] Malaria eradication is critically dependent on new therapeutics that target resistant Plasmodium parasites and block transmission of the disease. Here, we report that pantothenamide bioisosteres were active

Importance of factors determining the effective lifetime of a mass, long-lasting, insecticidal net distribution: a sensitivity analysis (Publications)
ensemble of 14 stochastic individual-based model variants for malaria in humans was used, combined with a deterministic model for malaria in mosquitoes. RESULTS: The effective lifetime was most sensitive [...] BACKGROUND: Long-lasting insecticidal nets (LLINs) reduce malaria transmission by protecting individuals from infectious bites, and by reducing mosquito survival. In recent years, millions of LLINs have [...] chemically and are destroyed, making repeated interventions necessary to prevent...

Treatment of afebrile malaria reduced inflammation [...] biomarkers, hepcidin, iron absorption, and utilization pre- and posttreatment in children with afebrile malaria, hookworm, and Schistosoma haematobium infection.

Resistance to Artemisinin Combination Therapies (ACTs): do not forget the partner drug! (Publications)
Artemisinin-based combination therapies (ACTs) have become the mainstay for malaria treatment in almost all malaria endemic settings. Artemisinin derivatives are highly potent and fast acting antimalarials; [...] regimen. When introduced, ACTs were highly efficacious and contributed to the steep decrease of malaria over the last decades. However, parasites with decreased susceptibility to artemisinins have emerged [...] ce and potential solutions to extend the useful therapeutic lifespan of the...
Following in Soper's footsteps: northeast Brazil 63 years after eradication of <em>Anopheles gambiae</em> (Publications)
years ago was a new and horrifying experience. This African mosquito is an exceptionally effective malaria vector because it is well adapted to feeding upon people and to exploiting aquatic habitats associated [...] with our daily activities. Anopheles gambiae sensu lato probably accounts for most of the world's malaria deaths and socioeconomic burden. Fortunately, the Brazilian experience had a happy ending. The prospect [...] aegypti elimination, the Rockefeller Foundation and Brazilian...
