The Peruvian Clinical Trials Registry - REPEC is a non-profit online information system developed in 2007 by INS. It is a publicly accessible prospective registry aimed at providing information about clinical trials underway in Peru. REPEC also includes Registries for Trial Sites, Institutional Research Ethics Committees, Sponsors and Contract Research Organizations. REPEC contains records of clinical trials since 1995. Since December 14, 2012, the Peruvian National Institute of Health, by means of the General Office for Research and Technological Transfer (OGITT), has started a process to improve REPEC and to join the WHO International Clinical Trials Registry Platform (ICTRP) and to be acknowledged as a Primary Registry. More information about primary registries is available in ICRTP at http://apps.who.int/trialsearch/. (from website)

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

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.

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

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)

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.

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.

A repository of software packages written in Ruby.

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.
