Ran-GTPase regulates multiple cellular processes such as nucleocytoplasmic transport, mitotic spindle assembly, nuclear envelope assembly, cell-cycle progression and the mitotic checkpoint. The leishmanial Ran protein, in contrast with its mammalian counterpart which is predominately nucleoplasmic, is localized at the nuclear rim. The aim of the present study was to characterize the LdRan (Leis...

OBJECTIVE To evaluate the leishmanicidal activity of saponin, dasyscyphin C of Eclipta prostrata and sapogenin, gymnemagenol from Gymnema sylvestre leaves under in vitro conditions. MATERIALS AND METHODS Dasyscyphin C/Gymnemagenol were dissolved in phosphate buffered saline (PBS) and diluted with liquid medium to obtain concentrations ranging from 1000 to 15 mug /ml. The leishmanicidal activi...

Purpose: To develop a highly accurate molecular assay for evaluating the efficacy of metronidazole and some antifungal agents with meglumine antimoniate against L. infantum visceral leishmaniasis in different mouse tissues. Methods: The assay was performed with the Light-Cycler system using SYBR Green I and primers amplifying ca. 120-bp fragment from minicircles of the kinetoplast DNA (kDNA).Th...

Malaria complicating kala-azar That malaria may complicate kala-azar was recognized by the early workers on kala-azar in this country. Napier (1927) remarked that plasmodial and leishmanial infection must copyist in t.^e same r^fip-nt verv froouent.lv. but the occasions on which both parasites would be found in the same film of either peripheral blood or spleen puncture material were few. Malar...
