DeCS 2002 - Overview
Summary of changes to DeCS/MeSH 2002:
- 847 descriptors added representing concepts with no directly
corresponding descriptors in 2001 DeCS/MeSH
- 185 descriptors replaced with more up-to-date terminology
- 47 descritors eliminated
- 2041 cross references (synonyms) added
The following changes and additions are of particular importance
for DeCS/MeSH 2002:
Viruses
All viruses were reviewed and updated to conform with the 7th Report
of the International Committee on Taxonomy of Viruses (ICTV). The
most significant was the official approval of the concept of viral
species and the codification of the official form of virus species
names using the format of first letter of first word capitalized,
first letter of other words all lower case. Many new virus names
have been added to DeCS/MeSH and older terminology has been changed.
Ammong the significant changes the names of all genera in the family
Retroviridae have been revised. Most species and strains of HTLV
viruses (now under Deltaretrovirus) have been reorganized and specific
coxsackieviruses are now referred to as specific enteroviruses.
Complementary and Alternative Medicine
The terminology related to complementary and alternative medicine
has been re-structured into sub-groups in order to facilitate searching
those divisions. The field can most broadly be divided into physical,
sensory, mind-body and spiritual plus some which occur in more than
one category. Physical includes acupuncture, muscoloskeletal manipulations
done by professionals; sensory includes play-, dance-, sound-, color-
and other such therapies; mind-body includes biofeedback, breathing,
hypnosis, laughter, relaxation; spiritual includes faith, magic,
occultism, witchcraft; and unclassified includes homeopathy, phytotherapy,
natural childbirth.
Plants and Phytotherapy
Terminology related to plant family and genera headings have been
greatly expanded with more use of the scientific Latin binomial
names and less use of common names as preferred terminology. In
addition, indexing of studies involving plants for therapy will
now be coordinated with Phytotherapy and the most specific plant
(family, genus or species) in B6 that is available. Because of the
importance of what part of the plant is being used, coordinate indexing
will use specific Plant Components (B06.413).
Bioethics
Through joint effort with the Kennedy Institute of Ethics, there
was enlargement and enhancement of terminology in the area of bioethics.
This cooperative project was in preparation for the addition into
PubMed of the journal citations which formerly constituted the BIOETHICSLINE
database. Some 50 new descriptors were created and numerous other
changes were made in DeCS/MeSH.
Transport and Carrier Proteins
There are now 50 new categories of transport proteins under Membrane
Transport Proteins. In addition 34 headings that were formerly under
Carrier Proteins, Membrane Proteins or Permeases are now arrayed
under Membrane Transport Proteins. Many of the 2,018 Supplementary
Concept Records (SCRs) that were formerly heading mapped to Carrier
Proteins are now mapped to specific categories listed under membrane
transport proteins. Several non-mammalian organism-specific proteins
classes have been added to accomodate the increasing need for indexing
of proteins from model organisms. Many of the organism-specific
proteins listed in the SCR are now more clearly distinguished with
organism names and HM to these protein classes. The HMG proteins
have been organized according to new nomenclature guidelines, which
were published in: Trends Biochem Sci 2001 Mar; 26(3):152-3.
The new rules were established with the coordinated efforts of staff
from MeSH, NCBI and scientists working in the field of HMG protein
research.
