How does it work
CytoD 1.0 is a database of cytogenetic abnormalities. The database is populated with searches of PubMed
abstracts. In all the database (1.0, up to the end of 2004) contains searches of 17,510 abstracts. These abstracts are determined to be related
to cytogenetics because they contain standard cytogenetic abnormality terms.
The database allows users to search for publications using standard cytogenetics nomenclature. Please note this
is a beta-testing version. Searches may not be accurate and complete. If you have any questions, please feel free
to contact us. Your feedback will be greatly appreciated.
