Discussions about whether new biomedical technologies threaten or violate human dignity are now common. Indeed, appeals to human dignity have played a central role in national and international debates about whether to allow particular kinds of biomedical investigations. The focus of this paper is on chimera research. I argue here that both those who claim that particular types of human-nonhuman chimera research threaten human dignity and those who argue that such threat does not exist fail to make their case. I first introduce some of the arguments that have been offered supporting the claim that the creation of certain sorts of chimeras threatens or violates human dignity. I next present opponents' assessments of such arguments. Finally I critically analyze both the critics' and the supporters' claims about whether chimera research threatens human dignity.

Cesarean sections are one of the most commonly performed surgical operations worldwide. Though evidence suggests that non-medically indicated cesarean sections raise the health risks for mothers and their babies and result in increased costs of health care compared with vaginal deliveries, reports are common that the frequency of performance of this surgical procedure is far above WHO recommendations. Of special concern has been the current increase of cesarean delivery rates in some Latin American countries. Here we focus on Monterrey, Mexico, a city that has one of the highest rates of cesarean deliveries in the world. We explore aspects that relate to the practice of cesarean section that might shed light on determining why Monterrey has become the capital of cesarean sections.
