Article Types

Research Articles

Research Articles present important new research findings that represent a major advance in the field. Research Articles include an abstract, introduction, methods, results, and discussion sections, together with figures, tables, legends, and relevant citations. Research Articles are peer-reviewed.

Rapid Reports

Rapid Reports are short papers presenting important new findings that could potentially have a major impact on the field. The manuscript does not need to tell a complete story but must be compelling, innovative, and novel. The manuscript should not exceed 4,000 words, including references and figure legends, and 4 figures and/or tables. Rapid Reports will be peer reviewed within 10 days. If requested, authors will be asked to submit a revision 14 days after the first decision. A final decision on first revisions will be made within 5 days of resubmission. Authors will be encouraged to fully comply with reviewer comments and submit only one revision. All Rapid Reports accepted for publication will be highlighted in the online journal as "featured papers" and have the option for a podcast at the author's and editors' discretion.

Note: Only video files are permitted as supplemental data for Rapid Reports. Other types of supplemental files (e.g., figures, tables, appendixes, data sets) are not permitted.

Review Articles

Review Articles provide synthesis of state-of-the-art knowledge in a defined area highlighting new questions and future research directions. They include reviews of biological processes, systems, models, and technologies. The primary purpose of a Review Article is to educate readers by providing a comprehensive summary of completed works presented in a concise, unified format. The manuscript should be approximately 8,000 words, excluding references, with 4-6 figures and/or tables, and up to 100 references. The inclusion of previously published figures is permitted provided that permission is obtained from the copyright holder and the source is acknowledged. Inclusion of unpublished data is also permissible. Authors are encouraged to use figures to summarize biological processes. Typically, Review Articles are invited although presubmission enquiries to the editors are encouraged. All Review Articles are peer-reviewed.

Note: Prior to publication all Review Articles will be examined for originality using CrossCheck screening software to compare the submitted text to all available literature, including previous publications from the same author(s).

Mini-Reviews

Mini-Reviews are concise, punchy, and up-to-the-minute summaries of important new and emerging fields. The purpose of Mini-Reviews is to introduce readers to advances and trends in physiology that are outside their own area of expertise. Mini-Reviews should provide a synthesis of new areas of biology in a manner that is accessible to nonspecialists in the field. They should focus on advances in the past 1-3 years, although some historical context is permissible. The manuscript should be approximately 3,000 words, excluding references, with 1-3 figures and/or tables, and up to 50 references. The inclusion of previously published figures is permitted provided that permission is obtained from the copyright holder and the source is acknowledged. Inclusion of unpublished data is also permissible. Authors are encouraged to use figures to summarize biological processes. Typically, Mini-Reviews are invited although presubmission enquiries to the editors are encouraged. All Mini-Reviews are peer-reviewed. Periodically, collections of Mini-Reviews that are in related areas or associated with meetings or symposia will be assembled by the editors in Themes.

Note: Prior to publication all Mini-Reviews will be examined for originality using CrossCheck screening software to compare the submitted text to all available literature, including previous publications from the same author(s).

Perspectives

Perspectives serve as a forum in which to disseminate new and original lines of thinking in physiology. Perspectives go beyond the scope of invited reviews and should present original ideas that can be derived from our current knowledge base. Perspectives may challenge current dogma and will be considered for publication based on the scientific merit of the argument presented. Perspectives are short articles (maximum 1,500 words excluding references with 2 figures and/or tables). Perspectives are peer-reviewed.

Young Investigator Perspectives

Young Investigator Perspectives are editorials written by students, postdoctoral trainees, or investigators transitioning to an independent laboratory. These brief articles (maximum 1,000 words excluding references) may address different aspects of research training, teaching, career development strategies in academia and industry, networking strategies, work-life balance, exciting new technologies, or scientific topics relevant to our field. Typically, Young Investigator Perspectives are invited although presubmission enquiries to the editors are encouraged.

Innovative Methodology

Advances in physiology often require the development of new methods of data collection and analysis. Manuscripts submitted under this category should describe new methods for the recording, collection, and/or analysis of data relevant to understanding physiological processes. Manuscripts will be reviewed on the basis of the following criteria:

  • The novelty of the new method. Manuscripts that describe incremental improvements of established methods will not be published.
  • Description of the method in sufficient detail for replication by other investigators.
  • Description of the advantages and disadvantages of the new method, including its advance over established approaches.
  • Demonstration that the new methodology is effective. Although an extensive study is not required, the manuscript should include a demonstration by experiment of "proof of principle."
  • Manuscripts should be of the length required to meet these criteria. Extensive technical details or mathematical derivations may be included as a supplement.

Editorials

Editorials provide commentary by the Editor-in-Chief, Associate Editors, and other scientists and experts on issues related to the Journal's mission as well as of general interest to our readers. Unsolicited editorials will be considered for publication by the editors.

Editorial Focus

Editorial Focus articles are commentaries on papers of unusual interest published in the Journal and selected by the Editor-in-Chief or Associate Editors to be highlighted by a brief Editorial Focus commentary. They should describe the most important conclusions of the paper and place the paper into context with the current state-of-the-art knowledge. They may highlight controversial issues, discuss strengths and weaknesses of the paper, and raise unanswered questions.

Letters to the Editor

In all cases, determining whether a proposed Letter to the Editor is acceptable for publication is a matter committed to the discretion of the editors. The Journal welcomes Letters to the Editor. Letters, including an informative title, should be short, approximately one journal column (500 words). Letters are reviewed by the editors and are subject to editing and possible abridgment. Letters to the Editor must be written by experts in the field under discussion, such expertise having been demonstrated by original research published by the author(s) in peer-reviewed journals indexed in the major services, such as PubMed. Letters to the Editor should not include original, unpublished data. If a proposed Letter is found acceptable, a copy will be sent to the author of the original article if applicable; that author will have an opportunity to provide a rebuttal with new material that will be considered for publication with the Letter. Letters to the Editor may also simply address matters of general interest to the readership.

Themes

Themes are collections of related Review Articles, Mini-Reviews, or Perspectives covering scientific areas of new discoveries, rapid progress, and exciting new opportunities in the field of gastrointestinal, liver and pancreatic research. For a list of current and past Themes articles, click here.
