Epidemiological Reviews. Volume 2. 1980

A volume such as the one considered here is different from many of the "Reviews" books available today: (1) it is sponsored by two major scientific societies, The Society for Epidemiologic Research and the International Epidemiological Association; and (2) it is published under the editorial management of a major journal, the American Journal ofEpidemiology. We expect such a volume to be well e...

High-volume and low-volume users of health services: United States, 1980.

41-Azido-41-de­oxy­rapamycin

The title compound, C(51)H(78)N(4)O(12), is a derivative of rapamycin, a triene macrolide anti-biotic mol-ecule isolated from Streptomyces hygroscopicus. The macrocyclic ring structure has 15 chiral centres, with one of the substituent hy-droxy groups giving an intra-molecular hydrogen bond to a ketone O-atom acceptor. The mol-ecules also form inter-molecular hy-droxy-ketone O-H⋯O hydrogen-bond...
