Ethical considerations in biomedical research: a personal view.

Premise: Ethical considerations are made when an experiment is planned and take a regulatory system of moral principles into account.
Discussion: Ethical considerations should first and foremost be made in order to protect the individual subject/animal from being exposed to any unethical and perhaps even illegal intervention and to ensure that the experimental conditions used are appropriate.
Summary: The main role of research ethics committees is to assess the scientific and ethical aspects of submitted protocols and follow up the trial until its closure.
