Nanoemulsions for increased penetrability and sustained release of leishmanicidal compounds.

In the last decade, the World Health Organization has driven the development of drugs for topical use in patients with cutaneous leishmaniasis (CL), the most prevalent clinical form of leishmaniasis, a neglected tropical disease. The chemicals C I, TC1, and TC2 were reported as promising antileishmanial drugs. We aimed to develop a topical nanoformulation that enhances the advantageous effect of C I, TC1, and TC2, guaranteeing higher stability and bioavailability of the pharmacologically active components through the topical route.

Strongyloides stercoralis proteome: A reverse approach to the identification of potential immunogenic candidates.

Strongyloides stercoralis is a parasite widely distributed in the tropical and subtropical areas in the world. Its treatment and diagnosis have a limitation as many other parasitic diseases. Nowadays, there is a great interest in designing an efficient epitope for vaccines or diagnostic.

Snake venomics of Bothrops punctatus, a semiarboreal pitviper species from Antioquia, Colombia.

Bothrops punctatus is an endangered, semi-arboreal pitviper species distributed in Panamá, Colombia, and Ecuador, whose venom is poorly characterized. In the present work, the protein composition of this venom was profiled using the 'snake venomics' analytical strategy. Decomplexation of the crude venom by RP-HPLC and SDS-PAGE, followed by tandem mass spectrometry of tryptic digests, showed that it consists of proteins assigned to at least nine snake toxin families.
