a mr 90 000 surface polypeptide of trypanosoma cruzi as a candidate for a chagas' disease diagnostic antigen. | trypanosoma cruzi (peru strain) trypomastigotes and epimastigotes were biosynthetically labeled with [35s]methionine, and the proteins were analyzed by two dimensional polyacrylamide gel electrophoresis (2d-page). 2d-page analysis of the trypomastigotes showed a complex array of polypeptides with distinct clusters at mr 88 000-92 000, isoelectric point (pi) 5.6-6.0, and mr 72 000-76 000, pi 5.6-5.8. 2d-page analysis of the epimastigotes did not show the cluster of polypeptides at mr 90 000. when ... | 1985 | 3932849 |
exploring the biological activities of echeveria leucotricha. | echeveria leucotricha j. a. purpus (crassulaceae) was evaluated for its potential antibacterial, antifungal, antiparasitic, cytotoxic and anti-inflammatory bioactivities. aerial parts were extracted with hexane, methanol and chloroform, and fractionated accordingly. biological activity was assessed in vitro against five gram-positive and four gram-negative bacteria, four human pathogenic fungi and the protozoan leishmania donovani. extracts and fractions showing bioactivities were further invest ... | 2013 | 22845689 |
antimicrobial, anti-inflammatory, antiparasitic, and cytotoxic activities of galium mexicanum. | ethnopharmacological relevance: to study the potential benefit of the traditional mexican medicinal plant galium mexicanum kunth (rubiaceae). hexane, chloroform, and methanol extracts as well as various fractions from these extracts were tested to determine antibacterial, antifungal, antiparasitic or anti-inflammatory activities in vitro. materials and methods: aerial parts of the plant were extracted with various solvents and fractionated accordingly. their antibacterial and antifungal activiti ... | 2011 | 21586319 |
