Discovery and characterization of potent, efficacious, orally available antimalarial plasmepsin X inhibitors and preclinical safety assessment of... (Publications)
Plasmepsin X (PMX) is an essential aspartyl protease controlling malaria parasite egress and invasion of erythrocytes, development of functional liver merozoites (prophylactic activity), and blocking [...] days. This work demonstrates the potential to deliver PMX inhibitors with in vivo efficacy to treat malaria.
Structure-activity relationships and antiplasmodial potencies of novel 3,4-disubstituted 1,2,5-oxadiazoles (Publications)
The 4-substituted 3-amino-1,2,5-oxadiazole 1 from the Malaria Box Project of the Medicines for Malaria Venture foundation shows very promising selectivity and in vitro activity against Plasmodium falciparum
Etiology of anemia among infants, school-aged children, and young non-pregnant women in different settings of south-central Côte d'Ivoire (Publications)
samples were subjected to standardized quality-controlled methods. We found high prevalence of anemia, malaria, inflammation, and deficiencies of iron, riboflavin, and vitamin A but low prevalence and intensities [...] factor for anemia in non-pregnant women. Our findings call for interventions to protect infants from malaria, improved intake of dietary iron, and given the importance of anemia of inflammation in school-aged
Micro-epidemiological structuring of <em>Plasmodium falciparum</em> parasite populations in regions with varying transmission intensities in Africa (Publications)
Background: The first models of malaria transmission assumed a completely mixed and homogeneous population of parasites. Recent models include spatial heterogeneity and variably mixed populations. However [...] pairs is predicted by relatedness in space and time. Conclusions: Our findings suggest that targeted malaria control will benefit the surrounding community, but unfortunately also that emerging drug resistance
On a mission to block transmission (Publications)
falciparum parasites could provide a platform to evaluate new drugs and vaccines aimed at blocking malaria transmission.

A simple and efficient tool for trapping gravid <em>Anopheles</em> at breeding sites (Publications)
BACKGROUND: No effective tool currently exists for trapping ovipositing malaria vectors. This creates a gap in our ability to investigate the behavior and ecology of gravid Anopheles. FINDINGS: Here we [...] ecology of gravid female Anophelines. It strongly implies that at least two of the major vectors of malaria in Africa land on the water surface during the oviposition process, and demonstrates that Anophelines
2,8-disubstituted-1,5-naphthyridines as dual inhibitors of <em>Plasmodium falciparum</em> phosphatidylinositol-4-kinase and hemozoin formation with... (Publications)
isolates and lab-raised drug-resistant strains of Pf. It was efficacious in the humanized NSG mouse malaria infection model at a single oral dose of 32 mg/kg. This compound was nonteratogenic in the zebrafish [...] human dose, indicating that this series has the potential to deliver a preclinical candidate for malaria.
Ancient Chinese methods are remarkably effective for the preparation of artemisinin-rich extracts of Qing Hao with potent antimalarial activity (Publications)
artemisinin is an important antimalarial drug and the herb itself is being grown and used locally for malaria treatment although this practice is controversial. Here we show that the ancient Chinese methods [...] in P. berghei infected mice. The implications of these results are discussed in the context of malaria treatment using A. annua infusions
Combining synthetic human odours and low-cost electrocuting grids to attract and kill outdoor-biting mosquitoes: field and semi-field evaluation of an... (Publications)
BACKGROUND: On-going malaria transmission is increasingly mediated by outdoor-biting vectors, especially where indoor insecticidal interventions such as long-lasting insecticide treated nets (LLINs) are [...] dusk and dawn. MLBs fitted with one, two or three electrocuting grids were compared outdoors in a malaria endemic village in Tanzania, where vectors had lost susceptibility to pyrethroids. MLBs with three
