MeSH Coming Attractions

MeSH Coming Attractions

[corrected 1999/08/10]

[published erratum appears in the NLM Technical Bulletin. 1999 Jul-Aug;(309):e1]

There were 303 [corrected 1999/01/11] descriptors added to the 1999 MeSH including 38 Publication Types. Five descriptors were deleted. A list of new Publication Types appears at the end of this article with their scope notes.

Changes to the following four categories are highlighted as of particular interest and are described in more detail later in this article:

1. Fungi
   Many new headings were added to the B5 tree and others modified to reflect developments in the taxonomy of the fungi.
   
   
2. Genetics
   New headings were added to the G5 tree and to the E5 tree (Techniques).
   
   
3. Delivery of Healthcare
   New headings were added to reflect recent Federal legislation and other developments.
   
   
4. Chemicals and Drugs
   A listing of all 71 new D category headings appears elsewhere in this issue. A new Subcategory D27 was created to group all MeSH Headings used as Pharmacologic Actions. A sample of this new Subcategory is shown later in this article under Chemical Actions and Uses (D27).

As always, comments and suggestions regarding possible new headings and changes to existing headings are welcome. Comments and suggestions may be made from the MeSH Home Page at: http://www.nlm.nih.gov/mesh/meshsugg.html.

Fungi (B5)

The Fungi tree was enhanced with 23 new MeSH headings to reflect developments in taxonomy. There are also many MeSH Heading (MH) changes and Tree changes as fungi names and taxonomies have undergone alterations.

Many fungi have a sexual (teleomorphic) and asexual (anamorphic or mitosporic) form. These are also called perfect and imperfect states. Each form (state) has its own taxonomic name.

Reciprocal cross references (see related notes) have been made between each related teleomorph and anamorph (mitosporic) fungus. For example, under the MeSH heading Colletrotrichum in the printed Annotated MeSH there will be the notation: see related Phyllacorales. And under Phyllacoralles there will be the notation: see related Colletrotrichum.

New 1999 Category D MeSH Vocabulary

The following terms, listed by Subcategory, are additions to MeSH for 1999. As appropriate, Pharmacologic Action(s) (PA:) are shown to the right of the term along with brief notes. An asterisk indicates the term was a Supplementary Chemical in 1998 MeSH.
