Ex vivo susceptibility to dihydroartemisinin in Plasmodium falciparum patient isolates from Eastern Rwanda, 2025

The emergence of artemisinin partial resistance (AR) in Plasmodium falciparum, characterized by mutations in the Plasmodium falciparum Kelch 13 (PfK13) gene and delayed parasite clearance, represents a significant threat to malaria control in Africa. While the Ring-Stage Survival Assay (RSA) is the phenotypic gold stan...

Evidence of artemisinin partial resistance in Zambia: a molecular epidemiology and clinical study.

BACKGROUND Artemisinin derivatives are central to first-line treatment of both uncomplicated and severe Plasmodium falciparum malaria. Emerging artemisinin partial resistance in east Africa threatens to spread across the continent. METHODS In two cross-sectional studies conducted across the ten provinces of Zambia in...

Comparative Genomics of COBRA-like Genes in Theobroma and Herrania Reveals Structural Conservation and Lineage-Specific Variation

COBRA-like (COBL) genes encode plant-specific proteins associated with cell-wall organization, cellulose deposition, and developmental processes. Despite their functional relevance in model plants and crops, this gene family remains poorly characterized in Amazonian Malvaceae species. Here, we performed a comparative g...
