The exact pathogenesis is not fully elucidated. The biochemical mechanisms of action of these substances have not yet been thoroughly elucidated. The pathophysiology is very complex and has been only partially elucidated. Many other xanthine analogues constituting the adenosine receptor antagonist class have also been elucidated. The genes regulating the complex developmental sequence have only been partly elucidated. The mechanisms of potential toxicity were also elucidated. Watson was now certain that DNA had a definite molecular structure that could be elucidated. Recently, a mechanism for autophagy has been elucidated. The pathway and enzymes have been elucidated and reported in detail. The intracellular details are still being elucidated. Nonetheless, much has been elucidated about the pharmacokinetics of spironolactone over the decades. The role of inflammatory processes in Gaucher disease is poorly elucidated. Similar mechanism of action has been elucidated in endometriosis and other endometrial diseases. Multiple subtypes have been elucidated, each of which require distinct treatment. Vasopressin was elucidated and synthesized for the first time by Vincent du Vigneaud.
