    “…By comparison, proteins exhibiting increased expression during development of the parasitic yeast phase comprised those involved in heat-shock responses, general metabolism, and cell-wall biosynthesis, as well as a small GTPase that regulates nuclear membrane transport and mitotic processes in fungi. …”

    “…BACKGROUND: Many microbes possess restriction-modification systems that protect them from parasitic DNA molecules. Unfortunately, the presence of a restriction-modification system in a given microbe also hampers genetic analysis. …”

    “…BACKGROUND: Due to the global occurrence of multi-drug-resistant malarial parasites (Plasmodium falciparum), the anti-malarial drug most effective against malaria is artemisinin, a natural product (sesquiterpene lactone endoperoxide) extracted from sweet wormwood (Artemisia annua). …”

    “…RESULTS: The pfmdr1 copy number was analysed for 115 isolates in the AM group, and for 109 isolates in the AL group. Parasites with increased pfmdr1 copy number had significantly reduced in vitro susceptibility to mefloquine, lumefantrine and artesunate. …”

    “…We report that in spite of their sequence differences, histone H2A 5' and 3' UTRs conferred a cell cycle dependent pattern of expression on the CAT reporter since de novo synthesis of CAT increased when parasites enter the S phase. Using one established L. infantum cell line we showed that CAT expression is controlled by the same regulatory events that control the endogenous histone gene expression. …”
