Selective lysis of erythrocytes infected with the trophozoite stage of Plasmodium falciparum by polyene macrolide antibiotics

Wiehart U.I.M.; Rautenbach, Marina; Hoppe H.C. (2006)

The continuous increase in strains of the human malaria parasite Plasmodium falciparum resistant to most front-line antimalarial compounds is reason for grave clinical concern. The search for new drugs led us to investigate ...

Membranes of class IIa bacteriocin-resistant Listeria monocytogenes cells contain increased levels of desaturated and short-acyl-chain phosphatidylglycerols

Vadyvaloo, Viveka; Hastings J.W.; Van der Merwe M.J.; Rautenbach, Marina (2002)

A major concern in the use of class IIa bacteriocins as food preservatives is the well-documented resistance development in target Listeria strains. We studied the relationship between leucocin A, a class IIa bacteriocin, ...

Lack of interaction between α2-adrenoceptors and dopamine D2-receptors in mediating their inhibitory effects on [3H]dopamine release from rat nucleus accumbens slices

Russell V.A.; Lamm M.C.L.; Taljaard J.J.F. (1993)

The α2-adrenoceptor agonist, UK14304, dose-dependently inhibited the electrically stimulated release of dopamine (DA) from rat nucleus accumbens slices. This effect was antagonized by idazoxan, confirming that it was an ...

Effects of α2- and β-adrenoceptor agonists on growth hormone secretion following lesion of the noradrenergic system of the rat

Jaffer A.; Daniels W.M.U.; Russell V.A.; Taljaard J.J.F. (1992)

The aim of the present investigation was to lesion the noradrenergic system and to measure the effect on growth hormone (GH) secretion following peripheral administration of α2- and β-adrenoceptor agonists. Direct injection ...

Characterization of the South African HIV type 1 subtype C complete 5′ long terminal repeat, nef, and regulatory genes

Scriba T.J.; De Villiers T.; Treurnicht F.K.; Zur Megede J.; Barnett S.W.; Engelbrecht S.; Van Rensburg E.J. (2002)

Human immunodeficiency virus type 1 (HIV-1) subtype C has become the major etiological agent in the global and especially African epidemic. To gain better understanding of the genetic diversity and rapid transmission of ...
