RESUMO
Monthly (April 2009 to May 2010) bottom-trawl sampling for Brachyplatystoma species along the rapids stretch of the Madeira River in Brazil revealed that Brachyplatystoma rousseauxii larvae and juveniles were present in low abundances in all areas and during all hydrological periods. The presence of larvae and juveniles throughout the hydrological cycle suggests asynchronous spawning in the headwaters of the Madeira River.

Intestinal transplantation is no longer an experimental procedure and is the treatment of choice for patients with irreversible intestinal failure that cannot be maintained on total parenteral nutrition (TPN). The intestine was a forbidden organ to be transplanted in humans until the 1980s due to its rich lymphoid content that precipitates either host-versus-graft or graft-versus-host alloreactivity.
