The document discusses the Nuremberg Code, which was established after the Nuremberg Trials in response to unethical medical experiments conducted by Nazi doctors during World War II without participants' consent. The Code established ethical research principles including voluntary informed consent, beneficence, and that experiments should avoid unnecessary harm or injury. It also states that researchers must be qualified and participants can withdraw at any time if they feel unable to continue. The 10-point Nuremberg Code was the first international code of research ethics.
