Searching Medical Literature Using

Basic Search

Pubplus provides three search options can be selected below the input box. The 'All Journals' option performs search of every journal indexed by PubMed and generates results that are identical to those from the PubMed website.

The default option is "Top Journals". This option allows filtering of results by the Pubplus algorithm and retains citation of papers that are published by top tier journals. The output results are in reverse chronological order. Similarily, selecting "Top Review Journals" option will only search for papers that are published in top tier review journals. Title Page

For example, to search recent high impact papers on T cells, submit 't cells' in the input box will return results similar to those shown below. Currently, Pubplus retrieves the most recent papers up to a maximum of 150 citations. Clicking on the title of the paper in each result will direct user to the corresponding PubMed page containing the abstract of that paper.

Find only Review Articles

To find only review articles, include the word 'review' together with the search term(s). This will return all matched citations that were also annotated as review papers by PubMed. An example output is shown below. In each of the result, note that the italicized word 'Review', labeled in red, is added to the left of the journal doi number. It is worth noting that not all review papers are annotated as such by PubMed; hence, they will not be included in the search result below. These unannotated review papers are classified as regular papers by PubMed; therefore, they cannot be selectively retrieved by specialized search keywords.

A different set of review articles can be found using 'Top Review Journal' options. These are papers published in top tier review journals. In this search mode, it is recommanded that the word 'review' is not included in the search term as this will removed misclassified citations from the search results.

Annotated Search

Pubplus allows annotation in search term with gene name/symbols. By default this feature is turned off. For example, to find papers related to role of the gene SRC in T cells, entering "t cells src" will produce an output as below.

To turn on annotation search, add @ in front the of gene name or symobls (eg. src becomes @src). This will return the results together with a brief of the description of the annotated Human gene(s). See below for a sample output. Up to three different genes can be annotated in the search term.
