Archives of Medical Research Guidelines for Authors Including New Information for Mandatory Manuscript and Peer Review Submission with the Elsevier Electronic System (EES)

Archives of Medical Research, published and distributed by Elsevier Inc., is the official medical research publication of the Instituto Mexicano del Seguro Social, IMSS (Mexican Institute of Social Security), Coordinación de Investigación en Salud (Health Sciences Research Coordination). This peer-reviewed Journal is published eight times per year and includes articles covering all areas of medical research relevant to human disease. Articles reporting original research that demonstrate pertinence to human medical investigation are encouraged and can be published as Original Articles, Preliminary Reports, Meta- Analysis, Opinions, Letters to the Editor, and Review Articles, written by experts in their field.

FULL LENGTH ARTICLE: This is a research study that describes original results of broad appeal with sufficient information to be critically evaluated. Sections must be presented in the following order: Title page, Abstract, Text, Acknowledgments, References, Tables, Figure Legends and Figures. The manuscript in full should not exceed 5000 words (including figure legends).

PRELIMINARY REPORTS: These are brief, definite reports of novel findings that are relevant to medical practice. They use the same structure as original articles (with the exception of an unstructured Abstract) and emphasis should be given to the concise presentation of results with sufficient explanation of experimental or methodological data. Limit to 2500 words including all aspects of the manuscript, and use no more than 2 tables or figures and 20 references. These brief manuscripts are reviewed for their novelty, immediacy, significance, and completeness and may report preliminary results.

REVIEW ARTICLES: Review articles will generally be by invitation of the Editorial Board. They should be concise but include controversies in the field as well as abundant bibliography; specific viewpoints may be included as long as they are well founded. Their main purpose is to provide up-to-date information about a topic by an expert in the field. Non-invited authors may submit review articles accompanied by a list of their own published works in the field that confirms their expertise in the area. The Editorial Board will then decide whether to accept or decline the manuscript. Review articles must contain no more than 7000 words.

OPINION: This is an expression of the author's opinion about a medical subject, 850 words including text, references, and acknowledgments, but not including the title page.

LETTERS TO THE EDITOR: Letters would preferably address articles published in Archives of Medical Research and should be structured with 500 words including text, references, and acknowledgments, but not including the title page.

Manuscripts written proficiently in scientific English are accepted from authors in any country and should be submitted only via , to Luis Benítez-Bribiesca, Editor-in-Chief. The Editorial Office of Archives of Medical Research is located at Centro Médico Nacional Siglo XXI, Unidad de Congresos, Bloque B, 4° piso, Av. Cuauhtémoc #330 Col. Doctores, 06725 México, D.F., México (Fax: +52 555 761 1503), E-mail address: Once all Elsevier Electronic System (EES) manuscript submission requirements are fulfilled, the work will be accepted for submittal and an immediate acknowledgment of receipt letter will automatically be sent to the corresponding author, along with an EES accession number to be used for all further correspondence. After peer review and acceptance, manuscript production status from the Elsevier Production Tracking System may be obtained at: In addition, all manuscript reviewers who kindly afford their much appreciated time and expertise to our peer review process will be asked to enter the EES system at for all communications regarding the manuscript.

Submission of a manuscript implies that it reports unpublished work and, if accepted for publication, will not be published elsewhere without Journal consent. A letter signed by every author expressly stating the specific contribution of each author must be sent with the electronic signature of all coauthors. This letter should express that the final manuscript has been seen and approved by all authors and that they have taken due care to ensure the integrity of the work. As stated in the Uniform Requirements (see later), credit for authorship requires substantial contributions to a) conception and design, or analysis and interpretation of data, b) drafting of the article or critical revision for important intellectual content; and c) final approval of the version to be published. All these conditions must be met and should be listed in each co-author letter.

Include separately the complete names and e-mail addresses of two internationally recognized experts in the scientific area of your manuscript to be used as peer reviewers at the discretion of the Editorial Board of the Journal.


Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (for more information on this and copyright, see An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.

Green open access

Authors can share their research in a variety of different ways and Elsevier has a number of green open access options available. We recommend authors see our green open access page for further information ( Authors can also self-archive their manuscripts immediately and enable public access from their institution's repository after an embargo period. This is the version that has been accepted for publication and which typically includes author-incorporated changes suggested during submission, peer review and in editor-author communications. Embargo period: For subscription articles, an appropriate amount of time is needed for journals to deliver value to subscribing customers before an article becomes freely available to the public. This is the embargo period and begins from the publication date of the issue your article appears in.

This journal has an embargo period of 12 months.

Research on Human Subjects. All research involving human subjects must contain a statement reflecting informed consent and approval from the scientific and ethics committees at the end of the Methods section. Conflict of interest should be specified.

Scope of the Journal. Medical research relevant to human disease.

Natural Products. Studies mentioning the use of natural products must first describe active compounds if known, and significant actions. All active agents should be sufficiently identified with chemical names as well as registry numbers and common names where appropriate. Studies that do not include these may be rejected without further review. The use of purified agents is encouraged.

Form. Manuscripts should be submitted only electronically via the EES system with text and tables preferably in Word format. Number pages consecutively, beginning with the title page.

Article structure

Manuscript Preparation. Assemble the manuscript in this order: Title page, Abstract, Text, Acknowledgments, References, Tables, Figure Legends and Figures. Prepare the manuscript in Word using 12 point Times New Roman font, with 1 inch margins all around, flush left margin without paragraph indents, unjustified right margin. This format includes the title page, where all information should be presented as previously mentioned. Do not boldface any information unless it is explained and necessary. Do not center any information.

Organization. Organize manuscripts as follows:

Title Page. The title page should contain a brief, concise title of not more than 150 characters. Titles should accurately reflect the content of the article. Provide a running title of no more than 50 characters. The Editors of Archives of Medical Research reserve the right to modify titles when deemed appropriate. Following the title and running title, all author names should be listed, without any degrees or titles. Affiliations (without street addresses) should be listed below author names, using a superscript letter to identify the authors with their corresponding affiliation. The author to whom correspondence should be sent should be listed below the affiliations and should include complete name, street address, city, state, country, postal code, FAX number (if applicable), and e-mail address (obligatory for submission).

Abstract. Include a Structured Abstract (Sections entitled Background, Aim of the study, Methods, Results, and Conclusions, no more than 250 words) followed by four to six key words or short phrases for cross-indexing. Refer to the Medical Subject Headings-Annotated Alphabetic List (National Institutes of Health, National Library of Medicine, Library Operations, Medical Subject Headings, Bethesda, MD 20894, USA, ) for internationally accepted subject headings. Do not cite References in the Abstract.

Sections should be in the following order: Introduction, Materials and Methods, Results, Discussion, and Conclusion. Acknowledgments (if mentioned), and References follow the text. Tables, with included titles, and Figure Legends follow. Figures should be sent separately. See Section on Illustrations. When using abbreviations, clearly explain at first mention and use abbreviation consistently thereafter. Do not overuse abbreviations.

Tables and Figures. Be sure that all Tables and Figures are mentioned in the text. The publisher will prepare the final layout of all Tables and Figures appropriately, as close to the mention in the text as possible. It is not necessary to indicate where Tables and Figures should be placed. No more than 6 tables and/or figures will be regularly accepted (exceptions may be discussed). Tables or Figures used from another published source (either exactly or closely adapted) require written permission from the publisher. It is the author's responsibility to obtain this permission upon acceptance of the manuscript by Archives of Medical Research. Elsevier will not publish any material that has been previously published without this permission. Manipulation of images for the purposes of deception or fraud is considered an ethical abuse and precludes the suspension of authors to publish again in this journal.

Tables. Each Table should be typed, double-spaced, on a separate page using Word format. Tables should be self-contained and self-explanatory. Provide a title for each table and use Arabic numbers. Do not use vertical lines to separate information within the table. Avoid the use of both tables and graphs to illustrate the same results and detailed description of information in either within the text that can be easily observed in the Tables and Figures. Use superscript letters for table legends.

Illustrations. Instructions for submitting Figures may be found on the EES page ( under Author Information Artwork Guidelines. Original illustrations should be professionally designed, in two dimensions, separately from the text (Tables are included with the Text), and submitted with the manuscript in recent versions of software programs. (Elsevier recommends that only JPEG, EPS, or PDF formats be used for electronic artwork.) Figure size must be at least 8.5 cm (maximum 17.6 cm) in width. Resolution of the jpg images must be at least 300 dpi. Color illustrations are encouraged; however, the cost of color printing is at the author's expense and arranged directly with the publisher ( The electronic version will contain color illustrations.

References. Accuracy of references is the responsibility of the authors. Copy authors' names, article titles and other publisher information. Confirm that all references mentioned in the text are presented in the Reference section at the end of the paper (and vice versa). References mentioned within text should be presented in Arabic numbers in parentheses and appear before the ending punctuation if at the end of the sentence. Do not superscript reference numbers. References are numbered sequentially in the text. The Reference list at the end of the paper should be numbered in the order as mentioned in the text and must match the in-text citation. Limit the number of authors listed to three, after that, use et al. References may contain only published works and papers in press. Works in progress, manuscripts submitted but not yet accepted, unpublished data, and personal communications may only be acknowledged (in parentheses) within the text (including year).

Reference management software
Most Elsevier journals have a standard template available in key reference management packages. This covers packages using the Citation Style Language, such as Mendeley ( and also others like EndNote ( and Reference Manager ( Using plug-ins to word processing packages which are available from the above sites, authors only need to select the appropriate journal template when preparing their article and the list of references and citations to these will be formatted according to the journal style as described in this Guide. The process of including templates in these packages is constantly ongoing. If the journal you are looking for does not have a template available yet, please see the list of sample references and citations provided in this Guide to help you format these according to the journal style.

If you manage your research with Mendeley Desktop, you can easily install the reference style for this journal by clicking the link below:
When preparing your manuscript, you will then be able to select this style using the Mendeley plug-ins for Microsoft Word or LibreOffice. For more information about the Citation Style Language, visit
