E!Canasta: A card game to teach ATP synthesis and metabolic regulation in biochemistry classes.

Understanding ATP formation is essential for learning metabolism and is central to grasping metabolic processes as a whole. However, due to the high level of abstraction, the number of intermediate substrates, the connections, and integrated regulation, its comprehension often poses a challenge. This and the fact that traditional teaching methods struggle when dealing with highly abstract concepts, game-based strategies present a more concrete and dynamic alternative, which led to the creation of E!Canasta (card game).

Mitochondrial behavior during nuclear and mitochondrial DNA repair in Trypanosoma cruzi epimastigotes.

Different genotoxic agents can lead to DNA single- and double-strand breaks, base modification and oxidation. As most living organisms, Trypanosoma cruzi is subjected to oxidative stress during its life cycle; thus, DNA repair is essential for parasite survival and establishment of infection. The mitochondrion plays important roles beyond the production of ATP.

Synthesis and evaluation of the antileishmanial activity of silver compounds containing imidazolidine-2-thione.

A new series of silver compounds could be of interest on designing new drugs for the treatment of leishmaniasis. The compounds [Ag(phen)(imzt)]NO(1), [Ag(phen)(imzt)]CFSO(2), [Ag(phen)](BF)·HO (3), [Ag(imzt)](NO)(4), and imzt have been synthesized and evaluated in vitro for antileishmanial activity against Leishmania.
