Morphiceptin

Morphiceptin is a tetrapeptide (Tyr-Pro-Phe-Pro-NH₂) that is a selective μ-opioid receptor agonist. It is derived from β-casomorphin and has over 1,000 times selectivity for μ- over δ-opioid receptors. When injected intracerebroventricularly (into the ventricular system of the brain), morphiceptin had an analgesic ED₅₀ of 1.7 nmol per animal. The analgesic effects of morphiceptin were reversed by naloxone, meaning that the analgesic effect is mediated by the μ-opioid receptor.

Palestine Liberation Organization

The Palestine Liberation Organization (PLO) (Arabic: منظمة التحرير الفلسطينية‎;  Munaẓẓamat at-Taḥrīr al-Filasṭīniyyah ) is an organization founded in 1964 with the purpose of the "liberation of Palestine" through armed struggle. It is recognized as the "sole legitimate representative of the Palestinian people" by over 100 states with which it holds diplomatic relations, and has enjoyed observer status at the United Nations since 1974. The PLO was considered by the United States and Israel to be a terrorist organization until the Madrid Conference in 1991. In 1993, the PLO recognized Israel's right to exist in peace, accepted UN Security Council resolutions 242 and 338, and rejected "violence and terrorism"; in response, Israel officially recognized the PLO as the representative of the Palestinian people.

Founding

At its first summit meeting in Cairo in 1964, the Arab League initiated the creation of an organization representing the Palestinian people. The Palestinian National Council convened in Jerusalem on 28 May 1964. Concluding this meeting the PLO was founded on 2 June 1964. Its stated goal was the "liberation of Palestine" through armed struggle.
