Recent data have found that Plasmodium ovale can be separated in two distinct species: classic and variant P. ovale based on multilocus typing of different genes. This study presents a P. ovale isolate from a patient infected in Ghana together with an analysis of the small subunit RNA, cytochrome b, cytochrome c oxidase I, cysteine protease and lactate(More)
We present an attractive new system for the specific and sensitive detection of the malaria-causing Plasmodium parasites. The system relies on isothermal conversion of single DNA cleavage-ligation events catalyzed specifically by the Plasmodium enzyme topoisomerase I to micrometer-sized products detectable at the single-molecule level. Combined with a(More)
Human topoisomerase I has been suggested to be implicated in the maintenance of genomic stability via its ability to regulate genome topology during transcription and replication. In the present study, we demonstrate by whole-genome array comparative genomic hybridization (aCGH) and fluorescence in situ hybridisation (FISH) analysis that topoisomerase I(More)
The assembly, structure, and stability of DNA nanocages with the shape of truncated octahedra have been studied. The cages are composed of 12 double-stranded B-DNA helices interrupted by single-stranded linkers of thymidines of varying length that constitute the truncated corners of the structure. The structures assemble with a high efficiency in a one-step(More)
A DNA nanocage has been recently characterized by small-angle X-ray scattering (SAXS) and cryo-transmission electron microscopy as a DNA octahedron having a central cavity larger than the apertures in the surrounding DNA lattice. Starting from the SAXS data, a DNA nanocage has been modeled and simulated by classical molecular dynamics to evaluate in silico(More)
Control of diseases inflicted by protozoan parasites such as Leishmania, Trypanosoma, and Plasmodium, which pose a serious threat to human health worldwide, depends on a rather small number of antiparasite drugs, of which many are toxic and/or inefficient. Moreover, the increasing occurrence of drug-resistant parasites emphasizes the need for new and(More)
