GDV1 induces sexual commitment of malaria parasites by antagonizing HP1-dependent gene silencing (Publications)
Malaria is caused by Plasmodium parasites that proliferate in the bloodstream. During each replication cycle, some parasites differentiate into gametocytes, the only forms able to infect the mosquito vector [...] vector and transmit malaria. Sexual commitment is triggered by activation of AP2-G, the master transcriptional regulator of gametocytogenesis. Heterochromatin protein 1 (HP1)-dependent silencing of ap2-g
The impact of the scale-up of malaria rapid diagnostic tests on the routine clinical diagnosis procedures for febrile illness: a series of repeated... (Publications)
BACKGROUND: This paper examines the impact of the scale-up of malaria rapid diagnostic tests (RDT) on routine clinical diagnosis procedures for febrile illness in primary healthcare settings in Papua New [...] pre- and post-RDT scale-up and between febrile patients who tested either negative or positive for malaria infection by RDT (post scale-up only). RESULTS: A total of 1809 observations from 120 health facilities [...] scale-up has led to a reduction in body temperature measurement....
Challenges of DHS and MIS to capture the entire pattern of malaria parasite risk and intervention effects in countries with different ecological... (Publications)
multiple indicator cluster survey. Malaria parasitological data were collected, but the survey period did not overlap with the high malaria transmission season. A malaria indicator survey (MIS) was also conducted [...] conducted during the same year, within the malaria peak transmission season. This study compares estimates of the geographical distribution of malaria parasite risk and of the effects of interventions [...] used to identify the most important climatic predictors and indicators of ...
Investigating sulfoxide-to-sulfone conversion as a prodrug strategy for a phosphatidylinositol 4-kinas inhibitor in a humanized mouse model of malaria (Publications)
its corresponding sulfone metabolite, were evaluated in the NOD-scid IL2Rgamma(null) (NSG) murine malaria disease model of Plasmodium falciparum infection. We hypothesized that the sulfoxide would serve [...] dosed, thereby demonstrating that the sulfoxide served as an effective prodrug for the treatment of malaria.
Efficacy of artemether-lumefantrine and dihydroartemisinin-piperaquine for the treatment of uncomplicated malaria in Papua New Guinea (Publications)
dihydroartemisinin-piperaquine (DHA-PPQ) as the first- and second-line treatments for uncomplicated malaria, respectively. This study was conducted to assess the efficacy of both drugs following adoption of [...] CONCLUSIONS: AL and DHA-PPQ were efficacious as first- and second-line treatments for uncomplicated malaria in PNG. Continued in vivo efficacy monitoring is warranted considering the threat of resistance to
Community-based prevalence of typhoid fever, typhus, brucellosis and malaria among symptomatic individuals in Afar Region, Ethiopia (Publications)
650 suspected individuals for malaria, 16 (2.5%) were found positive for P. falciparum infection. CONCLUSION: In this study, typhoid fever, typhus, brucellosis and malaria were observed among symptomatic [...] scarcity of proper diagnostic tools, febrile illness related symptoms are often misdiagnosed as malaria. Information on causative agents of febrile illness related symptoms among pastoral communities in [...] based cross-sectional survey, we assessed the prevalence of typhoid fever,...
Baseline exposure, antibody subclass, and hepatitis B response differentially affect malaria protective immunity following RTS,S/AS01E vaccination in... (Publications)
IgG4, subclass responses. Age, site, previous malaria episodes, and baseline characteristics including antibodies to CSP and other antigens reflecting malaria exposure and maternal IgGs, nutritional status [...] anti-HBsAg antibodies induced by RTS,S/AS01E vaccination were associated with malaria protection. In contrast, higher malaria exposure at baseline and non-cytophilic IgG responses to CSP were associated [...] BACKGROUND: The RTS,S/AS01E vaccine provides partial protection against malaria...
The promise, problems and pitfalls of mass drug administration for malaria elimination: a qualitative study with scientists and policymakers (Publications)
mass drug administration (MDA). This article explores attitudes towards and perceptions of MDA for malaria elimination among policymakers and leading malariologists. Methods: Thirty-two semistructured interviews [...] with policymakers (n=17) and principal investigators (n=15) selected based on their involvement in malaria prevention, control and elimination in the GMS. Interviews were audio recorded and transcribed for [...] Results: Researchers and policymakers described reluctance and...
