    Changes in the frequencies of Plasmodium falciparum dhps and dhfr drug-resistant mutations in children from Western Kenya from 2005 to 2018: the rise of Pfdhps S436H 

    Pacheco, M. Andreína; Schneider, Kristan A.; Cheng, Qiuying; Munde, Elly O.; Ndege, Caroline; Onyango, Clinton; Raballah, Evans; Anyona, Samuel B.; Ouma, Collins; Perkins, Douglas J.; Escalante, Ananias A. (Malaria Journal, 2020-10-22)
    Background Sulfadoxine-pyrimethamine (SP) is the only anti-malarial drug formulation approved for intermittent preventive treatment in pregnancy (IPTp). However, mutations in the Plasmodium falciparum dhfr (Pfdhfr) and ...

    Direct detection of bacteremia by exploiting host-pathogen interactions of lipoteichoic acid and lipopolysaccharide 

    Kubicek-Sutherland, Jessica Z.; Vu, Dung M.; Aneesa, Noormohamed; Mendez, Heather M.; Stromberg, Loreen R.; Pedersen, Christine A.; Hengartner, Astrid C.; Klosterman, Katja E.; Haley, A. Bridgewater; Otieno, Vincent; Cheng, Qiuying; Anyona, Samuel B.; Ouma, Collins; Raballah, Evans; Perkins, Douglas J.; McMahon, Benjamin H.; Mukundan, Harshini (Scientific Reports, 2019-04-17)
    Bacteremia is a leading cause of death in sub-Saharan Africa where childhood mortality rates are the highest in the world. The early diagnosis of bacteremia and initiation of treatment saves lives, especially in high-disease ...

    Cyclooxygenase-2 haplotypes influence the longitudinal risk of malaria and severe malarial anemia in Kenyan children from a holoendemic transmission region. 

    Anyona, Samuel B; Hengartner, Nicolas W; Raballah, Evans; Ong'echa, John Michael; Lauve, Nick; Cheng, Qiuying; Fenimore, Paul W; Ouma, Collins; Lambert, Christophe G; McMahon, Benjamin H; Perkins, Douglas J (Journal of Human Genetics, 2019-10-29)
    Cyclooxygenase-2 [(COX-2) or prostaglandin endoperoxide H2 synthase-2 (PTGS-2)] induces the production of prostaglandins as part of the host-immune response to infections. Although a number of studies have demonstrated the ...

    Integrated OMICS platforms identify LAIR1 genetic variants as novel predictors of cross-sectional and longitudinal susceptibility to severe malaria and all-cause mortality in Kenyan children 

    Achieng, Angela O.; Hengartner, Nicolas W.; Raballah, Evans; Cheng, Qiuying; Anyona, Samuel B.; Lauve, Nick; Guyah, Bernard; Foo-Hurwitz, Ivy; Ong'echa, John M.; McMahon, Benjamin H.; Ouma, Collins; Lambert, Christophe G.; Perkinsa, Douglas J. (EBioMedicine, 2019-07-02)
    Background Severe malarial anaemia (SMA) is a leading cause of childhood mortality in holoendemic Plasmodium falciparum regions. Methods To gain an improved understanding of SMA pathogenesis, whole genome and transcriptome ...

    Ingestion of hemozoin by peripheral blood mononuclear cells alters temporal gene expression of ubiquitination processes 

    Anyona, Samuel B.; Cheng, Qiuying; Raballah, Evans; Hurwitz, Ivy; Lambert, Christophe G.; McMahon, Benjamin H.; Ouma, Collins; Perkins, Douglas J. (Biochemistry and Biophysics Reports, 2022-01-11)
    Plasmodium falciparum (Pf) malaria is among the leading causes of childhood morbidity and mortality worldwide. During a natural infection, ingestion of the malarial parasite product, hemozoin (PfHz), by circulating phagocytic ...
