The results reflect the frequency of OMLs diagnosed in a specialized service in south of Chile and many countries around the world and will allow the establishment of preventive politics and adequacy of the clinical services.
Use and exploitation of channel waters by the black-browed albatross
This study presents the first record on the foraging distribution of the only known inner-channel colony of albatrosses in the world, using high-resolution GPS loggers and indicates a significant smaller foraging range during chick-guard compared with conspecifics from Diego Ramirez and Falklands/Malvinas Islands.
Toxic and therapeutic effects of Nifurtimox and Benznidazol on Trypanosoma cruzi ex vivo infection of human placental chorionic villi explants.
The presence of T. cruzi antigens and DNA in infected explants suggests that these drugs do not impair parasite invasion into the HPCVE and support the need for the development of more effective and better-tolerated drugs.
Mapping ecosystem services for marine spatial planning: Recreation opportunities in Sub-Antarctic Chile
The ecosystem services approach has increasingly emerged as a core requirement of ecosystem-based management of the marine space. In this context, explicit quantification and mapping of ecosystem…
Identifying high-value areas to strengthen marine conservation in the channels and fjords of the southern Chile ecoregion
Abstract Although Chile has been establishing marine protected areas since the 1960s, studies to identify representative areas for marine biodiversity conservation at the ecoregional scale are…

The Antarctic fur seal, Arctocephalus gazella, in the eastern South Pacific Ocean, first reported on Hoste Island, Cape Horn in 1973, and then on the Juan Fernandez Archipelago in 1982 and 1983, was…

The present review analyzes the current evidence about the trophoblast epithelial turnover as a local placental innate immune response as part of the innate immune system for congenital Chagas disease.
Trypanosoma cruzi induces trophoblast differentiation: a potential local antiparasitic mechanism of the human placenta?
It is proposed that T. cruzi induces differentiation in the trophoblast as part of a local antiparasitic mechanism of the placenta, which may contribute to increase the troPHoblast turnover.
Trypanosoma cruzi infectivity assessment in "in vitro" culture systems by automated cell counting.
Commercial software (MATLAB(®)) is used to quantify T. cruzi amastigotes and infected mammalian cells and it is concluded that this quantification method constitutes an excellent tool for evaluating the parasite load in cells and therefore constitutes an easy and reliable ways to study parasite infectivity.
