He is not confused about the cause of being and of coming to be, as it might seem in several passages. The paper’s focus is on Metaphysics Zeta 17. In contr...

NEP, ACE and Homologues: The Pathophysiology of Membrane Metalloproteases

The zinc metalloprotease, neprilysin (NEP), plays a role in the metabolism of cardiovascular, inflammatory and neuropeptides, including mitogenic peptides such as bombesin. In the cardiovascular system, NEP has a primary role in the inactivation of natriuretic peptides but also contributes to local metabolism of angiotensin, endothelins and bradykinin. Hence NEP is seen as a potential therapeut...
