    A library of 206 extracts from selected South African plants was screened in vitro against a panel of protozoan parasites, Plasmodium falciparum, Trypanosoma brucei rhodesiense, and Leishmania donovani. A CH(sub)2Cl(sub)2/MeOH ...
  • Hata, Y; Ebrahimi, SN; De Mieri, M; Zimmermann, S; Mokoka, T; Naidoo, Dashnie; Fouché, Gerda; Maharaj; Kaiser, M; Brun, R; Potterat, O; Hamburger, M (Elsevier, 2014-03)
    Human African trypanosomiasis is a neglected tropical disease in sub Saharan Africa that is fatal if left untreated. In a search for new natural products with antitrypanosomal activity, we recently identified abruquinones ...
  • Naidoo, Darryl; Forbes, A; Aït-Ameur, K; Brunel, M (SPIE, 2011-01)
    An experimental approach in generating Petal-like transverse modes, which are similar to what is seen in porro-prism resonators, has been successfully demonstrated. We hypothesize that the petal-like structures are generated ...
  • Naidoo, Darryl; Mafusire, C; Forbes, A (South African Institute of Physics, 2009-07)
    An optical aberration is a distortion of an image as compared to the object due to defects in an optical system
  • Mhlanga, T; Trichili, A; Dudley, Angela L; Naidoo, Darryl; Zghal, M; Forbes, A (SPIE, 2014-10-02)
    High-capacity data transmission has been implemented using single channel optical systems. This technique is limited and soon it will be unable to ful ll the growing needs for higher bit rate data transmission. Hence multi-mode ...
  • Nthambeleni, R; Moodley, N; Maharaj, VJ; Klimkait, T; Matter, A; Sewnarain, P; Naidoo, D (CSIR, 2010-09-01)
    HIV/AIDS is now the leading cause of death in Sub-Saharan Africa and has moved up to fourth place among all causes of death worldwide. According to estimates from the UNAIDS 2009 report (UNAIDS 2009) on the global AIDS ...
  • Litvin, IA; Ngcobo, S; Naidoo, Darryl; Ait-Ameur, K; Forbes, A (Optical Society of America, 2014-02)
    Laguerre–Gaussian beams with a nonzero azimuthal index are known to carry orbital angular momentum (OAM), and are routinely created external to laser cavities. The few reports of obtaining such beams from laser cavities ...
  • Omolo, JJ; Maharaj, V; Naidoo, D; Malebo, HM; Mtullu, S; Lyaruu, HVM; Koning, CB (American Journal of Research Communication, 2014)
    Phytochemical investigation of the stem and bark of Steganotaenia araliacea led to the isolation of two flavonoids. The structures of these compounds were identified as apigenin 4'-glucoside 1 and sophoraflavone B 2 using ...
  • Hendriks, A; Naidoo, Darryl; Roux, FS; Löpez-Mariscal, C; Forbes, A (SPIE, 2012-08)
    Phase-only spatial light modulators are now ubiquitous tools in modern optics laboratories, and are often used to generate so-called structured light. In this work we outline the use of a phase-only spatial light modulator ...
  • Ait-Ameur, K; Naidoo, Darryl; Ngcobo, S; Fromager, M; Litvin, I; Hasnaoui, A; Harfouche, A; Forbes, A (SPIE, 2015-02)
    A great number of laser applications need in place of the usual Gaussian beam a flat-top intensity profile in the focal plane of a focusing lens. In general the transformation of the laser beam from the Gaussian to the ...
  • Naidoo, Darryl; Forbes, A; Aït-Ameur, K; Fromager, M (SPIE, 2011-01)
    A method of decomposing a dual-directional laser beam into a forward propagating field and a backward propagating field for an apertured plano-concave cavity is presented. An intra-cavity aperture is a simple method of ...
  • Naidoo, Darryl; Aït-Ameur, K; Brunel, M; Forbes, A (Springer Verlag, 2012)
    In this paper we demonstrate experimentally the intra-cavity generation of a coherent superposition of Laguerre–Gaussian modes of zero radial order but opposite azimuthal order. The superposition is created with a simple ...
  • Naidoo, Darryl; Litvin, I; Laskin, A; Forbes, A (SPIE Proceedings, 2014-02)
    We explore an intra-cavity beam shaping approach to generate a Gaussian distribution by the metamorphosis of a Gaussian beam into a flat-top distribution on opposing mirrors. The concept is tested external to the cavity ...
  • Naidoo, Darryl; Aït-Ameur, K; Forbes, A (SPIE, 2011-08)
    In this paper the authors explore vortex beams and in particular the generation of single LG0l modes and superpositions thereof. Vortex beams carry orbital angular momentum (OAM) and this intrinsic property makes them ...
