Hemozoin-catalyzed precipitation polymerization as an assay for malaria diagnosis (Publications)
Methods to diagnose malaria are of paramount interest to eradicate the disease. Current methods have severe limitations, as they are either costly or not sensitive enough to detect low levels of parasitemia [...] increase is proportional to the concentration of hemozoin, with a detection limit of 0.85 ng mL(-1). Malaria parasites in human blood can be detected down to 10 infected red blood cells muL(-1). The assay could
Molecular monitoring of the diversity of human pathogenic malaria species in blood donations on Bioko Island, Equatorial Guinea (Publications)
ansmitted malaria are nucleic acid-based molecular approaches such as quantitative polymerase chain reaction. The study was undertaken to determine the prevalence of sub-microscopic malaria parasite infection [...] 9/59) and Plasmodium ovale (3.4%, 2/59). CONCLUSIONS: This study confirms that in malaria endemic settings, sub-patent malaria infections among blood donors are prevalent. In blood collected from healthy donors [...] Since the availability of molecular diagnostic methods in malaria...
Structure–activity relationship studies and <em>Plasmodium</em> life cycle profiling identifies pan-active N-aryl-3-trifluoromethyl... (Publications)
Structure-activity relationship studies involving N-aryl-3-trifluoromethyl pyrido[1,2-a] benzimidazoles (PBI) identified several compounds possessing potent in vitro activities against the asexual blo
Single-dose tafenoquine to prevent relapse of <em>Plasmodium vivax</em> malaria (Publications)
BACKGROUND: Treatment of Plasmodium vivax malaria requires the clearing of asexual parasites, but relapse can be prevented only if dormant hypnozoites are cleared from the liver (a treatment termed "radical
Early antischistosomal leads identified from<em> in vitro</em> and<em> in vivo</em> screening of the Medicines for Malaria Venture pathogen box (Publications)
Facing an almost dry drug development pipeline, screening the Pathogen Box from the Medicines for Malaria Venture (MMV), provides a unique opportunity to possibly expand the pool of potent molecules against
Adherence to intermittent preventive treatment for malaria in Papua New Guinean infants: a pharmacological study alongside the randomized controlled... (Publications)
(IPTi) trial that took place in Papua New Guinea showed an overall reduction of 29% of the risk of malaria when delivering single-dose sulfadoxine-pyrimethamine (SP) associated to 3 days of amodiaquine (AQ) [...] to discuss the efficacy of the intervention and on feasibility of self-administered preventive malaria treatment. METHODS AND FINDINGS: During the three-arm randomized double-blinded IPTi trial, each [...] studied when discussing the efficacy of the interventions in trials...
High cure rates and tolerability of artesunate-amodiaquine and dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria in... (Publications)
BACKGROUND: The Tanzanian National Malaria Control Programme (NMCP) and its partners have been implementing regular therapeutic efficacy studies (TES) to monitor the performance of different drugs used [...] mefantrine, which is the first-line anti-malarial for the treatment of uncomplicated falciparum malaria. Data on the performance of other artemisinin-based combinations is urgently needed to support timely [...] parasitological responses of ASAQ and DP for directly observed treatment of...
