Adeno-associated viruses (AAV) are ubiquitous in the human population (> 90% of adults
are seropositive) but have never been implicated as the cause of any disease. They were …

Segregation of components in a mixture by their differential partitioning in immiscible two-
phase systems is one of the classical separatory methods. This methodology was given …

The histamine-2 receptor antagonist cimetidine (10− 5 M) and the prostaglandin synthesis
inhibitor indomethacin (10− 8 M) augmented natural killer cell activity in the majority of …
