Antiprotozoal, antimycobacterial and cytotoxic potential of twenty-three British and Irish red algae (Publications)
rhodesiense, with Corallina officinalis and Ceramium virgatum being the most potent (IC(50) values 4.8 and 5.4 mug/ml), whilst none of the algal extracts inhibited the growth of T. cruzi. Except for Porphyra [...] extracts from all seaweeds also showed leishmanicidal activity with IC(50) values ranging from 16.5 to 85.6 mug/ml. Only the crude extract of Calliblepharis jubata showed some weak activity against M
Evaluation of <em>Plasmodium vivax</em> genotyping markers for molecular monitoring in clinical trials (Publications)
capillary electrophoresis to determine the extent of size polymorphism for 9 potential genetic markers (5 genes of merozoite surface proteins [msp] and 4 microsatellites) in 93-108 P. vivax-positive blood samples [...] respectively, followed by 2 fragments of msp1 and 2 other microsatellites. msp3alpha, msp4, and msp5 revealed limited polymorphism. CONCLUSIONS: Even for the most diverse markers, the highest allelic
Size-resolved emissions of organic tracers from light- and heavy-duty vehicles measured in a California roadway tunnel (Publications)

Most efforts to date have focused on emissions and apportionment PM10 or PM2.5 However, examining how these compounds are segregated by particle size in both emissions and ambient [...] markers apportioned to diesel and gasoline vehicles. The results are compared to previously conducted PM2.5 emissions testing using dynamometer facilities and othertunnel environments
Leishmanicidal cycloartane-type triterpene glycosides from <em>Astragalus oleifolius</em> (Publications)
Three known cycloartane glycosides cyclocanthoside E (3), astragaloside II (4) and astragaloside IV (5) were also isolated and characterized. All five compounds were evaluated for in vitro trypanocidal, [...] activities as well as their cytotoxic potential on primary mammalian (L6) cells. Except for the compound 5, all compounds showed notable growth inhibitory activity against Leishmania donovani with IC50 values

In winter months, the levels of PM2.5 pollution in Ulaanbaatar city (UB) can reach 1,985 micrograms per cubic meter — nearly 80 times the [...] found to have 40% lower lung function than children living in a rural area. In Ulaanbaatar (UB), a 3.5-fold increase in foetal deaths in the winter months has been documented. Preliminary analysis shows [...] impact level, the Project aims to contribute to: 1) reduced prevalence of...

Finally, 286 farmers were interviewed to assess perceptions [...] outdoor-biting mosquitoes. METHODS: In the first test, eave ribbons (0.1 m x 24 m each) treated with 1.5% transfluthrin solution were compared to untreated ribbons in 24 randomly selected huts in three migratory
