This collection of papers presents case studies and reflections on research bioethics from the standpoint of two Latin American academics involved in the teaching and dissemination of good practices and essential information on bioethics and various related topics. While limited in scope to a few key issues, the text may be read as an inspiration to comparative analyses of research practices involving human subjects and as an example of the reception of fundamental ideas on science and technology adopted in the Latin American region after their development in other areas of the globe.
