An immigration-death model to estimate the duration of malaria infection when detectability of the parasite is imperfect (Publications)
that allows for the accrual of infections with age. The models are fitted to a panel data set of malaria genotype of parasites belonging to the msp2 FC27 and 3D7 allelic families from a study of the dynamics
Age and seasonal variation in the transition rates and detectability of <em>Plasmodium falciparum</em> malaria (Publications)
of Plasmodium falciparum infections is unclear, although this is an important term in models of malaria transmission. It is problematical to determine the duration of infections because of the difficulty
Human antibodies to recombinant protein constructs of <em>Plasmodium falciparum</em> Apical Membrane Antigen 1 (AMA1) and their associations with... (Publications)
ectodomain (both FVO and 3D7 allele constructs) prior to a malaria transmission season were significantly associated with protection from malaria in the following 6 months, even after adjusting for age and
Malaria-infected mice are cured by oral administration of new artemisinin derivatives (Publications)
a new series of 23 trioxane dimers has been prepared. Eleven of these new trioxane dimers cure malaria-infected mice via oral dosing at 3 x 30 mg/kg. The clinically used trioxane drug sodium artesunate [...] on day 6-7 postinfection. At only 3 x 10 mg/kg oral dosing, seven dimers prolong the lifetime of malaria-infected mice to days 14-17, more than double the chemotherapeutic effect of sodium artesunate. Ten
Does radical cure of asymptomatic <em>Plasmodium falciparum</em> place adults in endemic areas at increased risk of recurrent symptomatic malaria? (Publications)
District (northern Ghana) was radically cured of malaria parasites to study subsequent incidence of malaria infection. During the following 20 weeks of the malaria transmission season, 49% experienced clinical [...] hypothesis that radical cure of P. falciparum enhances the risk and severity of subsequent clinical malaria attacks.
Contribution of influenza immunity and virosomal-formulated synthetic peptide to cellular immune responses in a phase I subunit malaria vaccine trial (Publications)
We have demonstrated recently in a phase Ia clinical trial that synthetic malaria peptides delivered by immuno-potentiating reconstituted influenza virosomes (IRIV) induced long-lived peptide-specific [...] have investigated the cellular immune responses specific for IRIV and the surface bound synthetic malaria peptides tested. After vaccination, in 50% (8/16) of the volunteers at least one positive lympho [...] pre-existing influenza specific T cell responses did not interfere negatively with...
Malaria vaccine candidate: design of a multivalent subunit alpha-helical coiled coil poly-epitope (Publications)
identification of new malaria antigens based on protein structural motifs was previously described. We identified and evaluated the malaria vaccine potential of fragments of several malaria antigens containing [...] (PBMC) of adults living in malaria-endemic areas. Affinity purified antigen-specific human antibodies and sera from P181-immunized mice recognised native proteins on malaria-infected erythrocytes in both [...] antigen-specific human antibodies were at high titers and associated with...
Should deep-sequenced amplicons become the new gold-standard for analysing malaria drug clinical trials? (Publications)
used to distinguish genotyping 'noise' from real low density signals, the local epidemiology of malaria transmission, and the potential impact of genetic signals from gametocytes. Results. AmpSeq greatly
