HSDB is a toxicology database that focuses on the toxicology of potentially hazardous chemicals. It provides information on human exposure, industrial hygiene, emergency handling procedures, environmental fate, regulatory requirements, nanomaterials, and related areas. The information in HSDB has been assessed by a Scientific Review Panel.
CTRI is a free, online public record system for registration of clinical trials being conducted in India since 2007. Initiated as a voluntary measure, since 2009 trial registration in the CTRI has been made mandatory by the Drugs Controller General of India (DCGI). While this register is meant primarily for trials conducted in India, the CTRI will also accept registration of trials conducted in other countries in the region, which do not have a Primary Registry of its own. Registered trials on CTRI are freely searchable from the WHO's search portal and the ICTRP, as well as from the CTRI site.
