The SAGE Social Science Thesaurus is a multidisciplinary vocabulary of the most important concepts in the social sciences. SAGE uses this vocabulary as its principal keyword vocabulary for automated tagging of content on SAGE Knowledge and SAGE Research Methods. You are welcome to browse, download, use and transform the vocabulary for any non-commercial purpose. The majority of concepts in the thesaurus have been mined from headwords in SAGE encyclopedias and other reference works. Relationships between concepts have been inferred from implicit structures in those works, for example subject indexes and readers' guides. As such, the thesaurus is a structured representation of what the editors of those reference works consider to be the most important concepts in the social sciences. Additional scraping work has extracted and structured concept-specific metadata, such as dates (for events and people) and definitions. In addition to broader-narrower relationships, concepts are grouped by type: concepts, people, organizations, events, methods, theories or laws.

RxNorm provides normalized names for clinical drugs and links its names to many of the drug vocabularies commonly used in pharmacy management and drug interaction software, including those of First Databank, Micromedex, and Gold Standard Drug Database. By providing links between these vocabularies, RxNorm can mediate messages between systems not using the same software and vocabulary.

RTECS is a compendium of data extracted from the open scientific literature. The data are recorded in the format developed by the RTECS staff and arranged in alphabetical order by prime chemical name. Six types of toxicity data are included in the file: (1) primary irritation; (2) mutagenic effects; (3) reproductive effects; (4) tumorigenic effects; (5) acute toxicity; and (6) other multiple dose toxicity. Specific numeric toxicity values such as LD50, LC50, TDLo, and TCLo are noted as well as species studied and route of administration used. For each citation, the bibliographic source is listed thereby enabling the user to access the actual studies cited. No attempt has been made to evaluate the studies cited in RTECS. The user has the responsibility of making such assessments.

Supplies biomedical investigators with rat models, embryonic stem cells, related reagents, and protocols they require for their research. In addition to repository, cryostorage and distribution functions, RRRC can facilitate acquisition of rat strains from other international repositories as well as provide consultation and technical training to investigators using rat models.

The Cuban Public Registry of Clinical Trials (RPCEC) is a website with a database of clinical trials, with national coverage. It was established in 2007 under the leadership of the National Coordinating Center of Clinical Trials (CENCEC) and with INFOMED collaboration. (from homepage)

A comprehensive listing of post-transcriptionally modified nucleosides from RNA -

Rnaloops stores the information about n-way junctions (where n≥3) found in experimentally determined rna 3d structures deposited in the protein data bank.

Identifiers represent computationally predicted and experimentally verified translatable circular RNAs (circRNAs) across six model species (human, mouse, rat, worm, fly, and zebrafish), including ribosome-associated circRNAs and their encoded peptides with systematic annotation of sequence, structure, and function.

Ribocentre is designed to contain comprehensive information of all natural ribozymes.
