    Development, characterization and antimalarial efficacy of dihydroartemisinin loaded solid lipid nanoparticles. 

    Omwoyo, Wesley; Melariri, Paula; Gathirwa, Jeremiah; Oloo, Florence; Mahanga, Geoffrey; Kalombo, Lonji; Ogutu, Bernhards; Swai, Hulda (Elsevier, 2016-04-01)
    Effective use of dihydroartemisinin (DHA) is limited by poor water-solubility, poor pharmacokinetic profile and unsatisfactory clinical outcome especially in monotherapy. To reduce such limitations, we reformulated DHA ...

    The water uptake of poly(tetrahydrofurfuryl methacrylate) 

    Riggs, P. D.; Braden, M.; Tilbrook, D. A.; Swai, Hulda; Clarke, R. L.; Patel, M. P. (Elsevier, 1999-03)
    Poly(tetrahydrofurfuryl methacrylate) possesses some unique characteristics with respect to its biocompatibility and behaviour in water. The water uptake is high (>70%) and very slow (over 3 yr), but the material remains ...
