水流指示器火警处理:PubMed RSS 订阅

RSS Feeds Available from PubMed
Note: This feature was implemented in PubMed on June 2, 2005.]
Pubmed的检索结果可以通过RSS订阅到Google阅读器。
在Pubmed检索结果界面，点击Seed To下拉框，选择RSS Feed选项。Figure 1).

This will take you to the RSS Options Page where you may name the feed and limit the number of items to be displayed by each feed (seeFigure 2). If the number of citations retrieved is greater than your "limit" number, you will have the option to link to PubMed to see the entire retrieval.

After clicking the Create Feed button, the system will generate an XML icon (seeFigure 3).

Click the XML icon to display a screen of XML. You don't need the code, just the the URL from the address line (seeFigure 4). Copy and paste this into the "subscribe" form located in your RSS reader. Web Browsers and RSS readers may use different options to copy the feed.

Once you have successfully subscribed to a PubMed RSS feed you will receive daily messages in your RSS reader (seeFigure 5).

RSS Update Strategy
PubMed RSS feeds will use the same "What's New" strategy used by My NCBI for updating saved searches.
Searches with untagged terms use the following query:
Query AND T1 : T2 [MHDA] NOT Query [TIAB] AND 0001 : T1 [EDAT]
Where:
Query = saved search.
T1 = the date and time the search was last updated.
T2 = today's date and time.
0001 = the date that will include all citations.
[MHDA] = the search tag for the MeSH date. This field reflects the date MeSH terms were added to the citation. (Note: until MeSH terms are added, the MHDA value is the same as the EDAT.)
[EDAT] = the search tag for the Entrez date field the date the citation was added to PubMed.
[TIAB] = the search tag for words in the Title and Abstract fields.
Searches for RSS feeds that include Search field tags or some Limits use an abbreviated "What's New" search to ensure that all citations are retrieved. This approach may result in some duplication of citations.
Searches that include these search tags or their aliases AU, PS, IP, TA, LA, PG, TI, TIAB, or VI use the following: Query AND T1 : T2 [EDAT].
Searches that include the Search Field tags (may be in addition to other tags) AD, FILTER, SB, RN, MAJR, MESH, PT, SI, SH, NM, or TW, use the strategy: Query AND T1 : T2 [MHDA]
RSS or Automatic E-mailed Updates?
Daily updates can be obtained using either the new RSS feed feature or the existing service offered by My NCBI. Updates provided by My NCBI are recommended for less frequent updates.
Technical Support for RSS Readers
NLM is unable to provide support for RSS readers or to test this service with a specific reader. Users interested in using this technology or who need technical support should enlist the help of their computer support staff.
