    Site Search Powered by Google

    A customized Google search form is available on top of the home page, on the right. The same search tool is available at the bottom of every page on this site and is featured below. This tool is available to help you in case you have an idea for further research. The search database is based on an index created for by Google. The crawler lag in keeping the index current is usually a few days. Surprising, since the Googlebot is usually at the site indexing it every day but it appears that the index is updated at Google's server farm only periodically. Most people are familiar with the format of Google's search results. Google has agreed to eliminate sponsored ads from the search results because of our non-profit status. Try the search — and use it often.

    Site Search Powered by Atomz

    If you are looking for something that was published recently, it is possible that the Googlebot has not visited and indexed the most recent materials on our website. However, an alternative custom search form powered by Atomz gives us the options of re-indexing whenever we choose — and we do try to keep this index current with frequent spidering instructions. Unfortunately, with this engine, we have to live with (sometimes inappropriate) sponsored ads: just ignore them and look at the site search results in the colored central region. This search form can also be found on the home page and several other locations.

    We also have an advanced search form that gives you much greater search flexibility and power – at the cost of greater complexity.

    Clinical Trial Databases

    US NCI and NIH Clinical Trials Databases

    National Cancer Institute: Comprehensive searchable registry presented by the US National Cancer Institute.

    National Institutes of Health: You may also search a wider database for all clinical trials (cancer related or otherwise) by using the following NIH link:

    WHO Clinical Trials Database

    ICTRP: Newly launched international search engine to centralize entries from a number of qualified registries around the world. While this is not a registry in itself, it does make the information from its several participating registries. The acronym stands for International Clinical Trials Registry Platform. We hope this registration platform will provide comprehensive coverage.

    "The mission of the WHO Registry Platform is to ensure that a complete view of research is accessible to all those involved in health care decision making. This will improve research transparency and will ultimately strengthen the validity and value of the scientific evidence base. "

    "The registration of all interventional trials is a scientific, ethical and moral responsibility."

    MEDLINEplus® Health Information

    logo link Consumer health information from the National Library of Medicine (NLM) and the National Institutes of Health (NIH).

    Constantly-updated medical news headline links and archived stories. Sources include the New York Times Syndicate, Reuters, and the AP News Service. The news link directory is maintained by the National Library of Medicine's MedlinePlus health information service.

    NCBI Databases

    The National Center for Biotechnology Information (NCBI) maintains a number of critical biotechnology databases, including PubMed (see below) that can be accessed by the public. Most of these databases are of interest to the specialist only, but PubMed is key to searching for citations on clinical research. Twenty one NCBI databases can be accessed through the following link:


    PubMed, a service of the National Library of Medicine, provides access to over 12 million MEDLINE citations back to the mid-1960's and additional life science journals. PubMed includes links to many sites providing full text articles and other related resources. This is undoubtedly a key resource for any kind of systematic investigation of the research literature on medical topics.

    If you are serious about using PubMed to conduct your own searches, it might be helpful for you to go through the PubMed Tutorial found at:

    You can launch your PubMed search from here. The drop-down menu gives you access to 16 other NCBI databases besides PubMed.
