Bioactivity of Fungal Endophytes as a Function of Endophyte Taxonomy and the Taxonomy and Distribution of Their Host Plants
(2013-09-16)Fungal endophytes – fungi that grow within plant tissues without causing immediate signs of disease – are abundant and diverse producers of bioactive secondary metabolites. Endophytes associated with leaves of tropical ... -
Randomized, Double-Blinded, Phase 2 Trial of WR 279,396 (Paromomycin and Gentamicin) for Cutaneous Leishmaniasis in Panama
(2013-07-15)In this randomized, double-blinded Phase 2 trial, 30 patients with Leishmania panamensis cutaneous leishmaniasis were randomly allocated (1:1) to receive once daily topical treatment with WR 279,396 (15% paromomycin + 0.5% ... -
Separation of Plasmodium falciparum Late Stage-infected Erythrocytes by Magnetic Means
(2013-02-20)Unlike other Plasmodium species, P. falciparum can be cultured in the lab, which facilitates its study 1 . While the parasitemia achieved can reach the ≈40% limit, the investigator usually keeps the percentage at around ... -
Antitrypanosomal Alkaloids from the Marine Bacterium Bacillus pumilus
(2012-09-18)Fractionation of the ethyl acetate extract of the marine bacterium Bacillus pumilus isolated from the black coral Antipathes sp. led to the isolation of five compounds: cyclo-(L-Leu-L-Pro) (1), 3-hydroxyacetylindole (2), ... -
