AIDSLINE (AIDS Information Online), produced by the U.S. National Library of Medicine, is a collection of bibliographic citations focusing on research, clinical aspects, and health policy issues related to AIDS (Acquired Immune Deficiency Syndrome). This database includes articles from over 3,000 journals published worldwide, as well as government reports, letters, technical reports, meeting abstracts and papers, monographs, special publications, theses, books, and audiovisual materials. Information in the AIDSLINE database is derived from the the following sources: MEDLINE, Health Planning and Administration, meeting abstracts from the International Conferences on AIDS, the Symposia on Non-human Primate Models of AIDS, and AIDS-related abstracts from the Annual Meetings of the American Society of Microbiology.
The following alphabetical list provides the two letter label, the relevant alias, and at least one example for all searchable AIDSLINE fields:

"dopamine agents*".xm.

MeSH Subject Headings are hierarchical, with up to twelve levels of
narrower terms from the top of a hierarchy. In order to retrieve a
term and all of its narrower terms, a subject heading must be
"exploded", that is, the subject heading and all narrower terms are
"OR'd" together. OVID pre-explodes highly-posted broader terms with
their narrower terms during loading. These pre-exploded MeSH Headings
appear in the XM field.
XS Exploded Subheading [Phrase Indexed]
ae.xs.
di.xs.
Sometimes multiple MeSH Subheadings can be logically grouped together.
Such related groups of subheadings are "pre-exploded" under one broad
subheading. This means that all the grouped subheadings can be
retrieved together by searching on the "pre-exploded" version of the
broad subheading.
The 2-letter codes for the pre-exploded subheadings appear in the
Exploded Subheadings (XS) field.
YR Year of Publication [Phrase Indexed]
