The Learning Resources Database is a catalog of interactive tutorials, videos, online classes, finding aids, and other instructional resources on National Library of Medicine (NLM) products and services. Resources may be available for immediate use via a browser or downloadable for use in course management systems.
Pillbox contains metadata for oral solid dosage form medications, derived from FDA drug labeling, including physical characteristics, active and inactive ingredients, National Drug Codes, information about firms marketing those products, selected information from RxNorm, and links to images provided by the National Library of Medicine.
HSDB was a toxicology database that focused on the toxicology of potentially hazardous chemicals. It provided information on human exposure, industrial hygiene, emergency handling procedures, environmental fate, regulatory requirements, nanomaterials, and related areas. The information in HSDB has been assessed by a Scientific Review Panel.
This version of HSDB data includes a subset of HSDB for downloading, but is no longer updated. HSDB data has been incorporated into PubChem.
Publication Types (Publication Characteristics) are Descriptors that indicate what an indexed item is, (i.e., its genre, rather than what it is about - for example, Historical Article). They may include Publication Components, such as Charts; Publication Formats, such as Editorial; and Study Characteristics, such as Clinical Trial.
They function as metadata, rather than being about the content. These records are searchable in PubMed as Publication Type [PT], and the terms in MEDLINE records are labeled as "PT" or rather than "MH" or . They are listed in category V of the MeSH Tree Structures.
This dataset includes all newly added MeSH Main Headings for 2023. Headings play a central role in MeSH vocabulary as a unit of Indexing and retrieval. With the exception of Class 3 Descriptors, all descriptors are organized into a numbered tree structure or hierarchy that allows users to browse in a orderly fashion from broader to narrower topics. Scope Notes provide a concise summary describing the meaning and scope of the MeSH Descriptor.
The MeSH 2023 Update - Add Report for SCRs lists new Supplementary Concept Records (SCRs) that have been added to MeSH for the upcoming new release. It also includes terms that replace deleted terms, as well as new entry combinations (new precoordinated descriptor heading that replaces an existing descriptor/subheading combination).
