Scope and policy
The purpose of the Brazilian Journal of Medical and Biological Research is to publish the results of original experimental research that contribute significantly to knowledge in medical and biological sciences. Major criteria for acceptance are scientific quality, originality, and conciseness. Preference will be given to manuscripts that develop new concepts or experimental approaches and are not merely repositories of data. Papers that report negative results require special justification for publication. Methodological papers shall be considered for publication provided they describe new principles or a significant improvement of an existing method.
The following papers will not be accepted for publication
Preparation of Research Manuscripts
The Brazilian Journal of Medical and Biological Research publishes original research articles of outstanding scientific significance. Manuscripts must be submitted in English. We will consider manuscripts of any length; we encourage the submission of both substantial full-length bodies of work and shorter manuscripts that report novel findings that might be based on a limited number of experiments. The key criteria are that the research clearly demonstrates its novelty, its importance to a particular field as well as its interest to those outside that discipline, and conclusions that are justified by the data.
Only those persons who contributed directly to the intellectual content of the paper should be listed as authors. Authors should meet all of the following criteria, thereby allowing persons named as authors to take public responsibility for the content of the paper.
It is important that you include a cover letter with your manuscript. Take the time to consider why this manuscript is suitable for publication in the Brazilian Journal of Medical and Biological Research. Why will your paper inspire the other members of your field, and how will it drive research forward? Please explain this in your cover letter.
The cover letter should also contain the following information:
Guidance on grammar, punctuation, and scientific writing can be found in the following sources:
The Brazilian Journal of Medical and Biological Research follows the reference format of the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, which can be found on the website of the National Library of Medicine (http://www.icmje.org/).
The writing style should be concise and accessible. Editors will make suggestions for how to achieve this, as well as suggestions for cuts or additions that could be made to the article to strengthen the argument. Our aim is to make the editorial process rigorous and consistent, but not intrusive or overbearing. Authors are encouraged to use their own voice and to decide how best to present their ideas, results, and conclusions.
Although we encourage submissions from around the globe, we require that manuscripts be submitted in American English. As a step towards overcoming language barriers, we encourage authors to seek the assistance of professional services available on the homepage of the journal/Service and Information.
Text footnotes, if unavoidable, should be numbered consecutively in superscript in the manuscript and written on a separate page following the abstract.
Abbreviations should be kept to a minimum. Define all abbreviations upon first use in the abstract and the text. Non-standard abbreviations should not be used unless they appear at least three times in the text.
NomenclaturevThe use of standardized nomenclature in all fields of science and medicine is an essential step toward the integration and linking of scientific information reported in published literature. We will enforce the use of correct and established nomenclature wherever possible: We strongly encourage the use of SI units.
Species names (e.g., Homo sapiens), genes, mutations, genotypes, and alleles should be italicized. Use the recommended name by consulting the appropriate genetic nomenclature database, e.g., HUGO for human genes. It is sometimes advisable to indicate the synonyms for the gene the first time it appears in the text.
The Recommended International Non-Proprietary Name (rINN) of drugs should be provided.
Authors should state in the cover letter that the manuscript is intended to be a Full-length Paper, Short Communication, Review Article, Overview, Concepts and Comments, or Case Report.
Each manuscript should clearly state its objective or hypothesis; the experimental design and methods used (including the study setting and time period, patients or participants with inclusion and exclusion criteria, or data sources and how these were selected for the study); the essential features of any interventions; the main outcome measures; the main results of the study; and a discussion placing the results in the context of published literature.
The manuscript should contain:
A short communication is a report on a single subject, which should be concise but definitive. The scope of this section is intended to be wide and to encompass methodology and experimental data on subjects of interest to the readers of the Journal.
The manuscript should contain:
A review article should provide a synthetic and critical analysis of a relevant area and should not be merely a chronological description of the literature. A review article by investigators who have made substantial contributions to a specific area in medical and biological sciences will be published by invitation of the Editors. However, an outline of a review article may be submitted to the Editors without prior consultation. If it is judged appropriate for the Journal, the author(s) will be invited to prepare the article for peer review. A minireview is focused on a restricted part of a subject normally covered in a review article.
The manuscript should contain:
An overview does not contain unpublished data. It presents the point of view of the author(s) in a less rigorous form than in a regular review or minireview and is of interest to the general reader.
The manuscript should contain:
Concepts and Comments
The Concepts and Comments section provides a platform for readers to present ideas, theories and views.
The manuscript should contain:
A case report should have at least one of the following characteristics to be published in the Journal:
The manuscript should contain:
Organization of the Manuscript
Most articles published in the Brazilian Journal of Medical and Biological Research will be organized into the following sections:
Continuous page numbers are required for all pages including figures. There are no specific length restrictions for the overall manuscript or individual sections. However, we urge authors to present and discuss their findings concisely. We recognize that some articles will not be best presented in our research article format. If you have a manuscript that would benefit from a different format, please contact the editors to discuss this further.
Authors and Affiliations
The abstract should briefly and clearly present the objective, experimental approach, new results as quantitative data if possible, and conclusions. It should mention the techniques used without going into methodological detail and mention the most important results.
Abbreviations should be kept to a minimum and should be defined in both the Abstract and text.

Material and Methods
Preparing figure files for submission
Please note that it is the responsibility of the author(s) to obtain permission from the copyright holder to reproduce figures (or tables) that have previously been published elsewhere. In order for all figures to be open-access, authors must have permission from the rights holder if they wish to include images that have been published elsewhere in non-open-access journals. Permission should be indicated in the figure legend, and the original source included in the reference list.
Supported file type
Micrographs should be treated like photographs with the following additional guidelines
Only published or accepted manuscripts should be included in the reference list. Meeting abstracts, conference talks, or papers that have been submitted but not yet accepted should not be cited. Limited citation of unpublished work should be included in the body of the text only. All personal communications should be supported by a letter from the relevant authors. Authors are responsible for the accuracy and completeness of their references and for correct text citation. When possible, references which are easily available in English should be cited.
The BJMBR uses the numbered citation (citation-sequence) method. References are listed and numbered in the order that they appear in the text. In the text, citations should be indicated by the reference number in parentheses. Multiple citations within a single set of parentheses should be separated by commas without a space (1,5,7) . Where there are 3 or more sequential citations, they should be given as a range (4-9).
Because all references will be linked electronically (doi), if possible, to the papers they cite, proper formatting of the references is crucial. For all references, list the first 6 authors followed by et al., Title of article, Journal (abbreviation), Year, Volume, Complete Pages, The Brazilian Journal of Medical and Biological Research follows the reference format of the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, which can be found on the website of the National Library of Medicine (http://www.nlm.nih.gov/bsd/uniform_requirements.html). Use the Medline journal abbreviations and follow the reference style shown on the Website noted above, with several exceptions. See below for details. If the author uses the program "Reference Manager", copy the file containing the style of the Brazilian Journal of Medical and Biological Research and place it in the folder of "Styles". When submiting the manuscript, send the file produced in Reference Manager (".rmd" and ".rmx" ) as an attachment.

How to submit a manuscript to the BJMBR
Manuscript criteria and information
The Brazilian Journal of Medical and Biological Research is a peer-reviewed electronic journal published monthly by the Associação Brasileira de Divulgação Científica (ABDC).
Submission of a manuscript to the Brazilian Journal implies that the data have not been published previously and will not be submitted for publication elsewhere while the manuscript is under review.
The following represent "prior publication": any printed material in excess of 500 words describing results or methods of a submitted/in press manuscript; published tables or illustrations that duplicate the content of a manuscript; electronic manuscripts or posters available via the Internet. When part of the material in a manuscript has been presented as a preliminary communication or in an unrefereed symposium, this should be cited as a footnote on the title page and a copy should accompany the submitted manuscript.
The Brazilian Journal of Medical and Biological Research (BJMBR) applies the Creative Commons Attribution License (CCAL) to all works published (read the human-readable summary or the full license legal code). Under the CCAL, authors retain ownership of the copyright for their article and can allow anyone to download, reuse, reprint, modify, distribute, and/or copy articles published in the BJMBR, as long as the original authors and source are cited. No permission is required from the publishers.
The main characteristic of research papers in the area of Cell Biology is the emphasis on the integration at the cellular level of biochemical, molecular, genetic, physiological, and pathological information. This section considers manuscripts dealing with either prokaryotic or eukaryotic biological systems at any developmental stage. Papers on all aspects of cellular structure and function are considered to be within the scope of Cell Biology by the BJMBR. The Editors encourage submission of manuscripts defining cell biology as an area of convergence of several other research fields, especially manuscripts providing insights into the cellular basis of immunology, neurobiology, microbial pathology, developmental biology, and disease. Manuscripts containing purely descriptive observations will not be published. Manuscripts reporting new techniques will be published only when adequately validated and judged by the Editors to represent a significant advance.
Biological activity of natural products
The Journal will consider papers for publication which describe the activity of substances of biological origin only if they satisfy all of the following criteria:
Editorial review and processing
The receipt of manuscripts is acknowledged immediately. Once a paper has been evaluated by peer review, the authors will be notified of the editorial decision.
Galley proofs will be sent to authors for the correction of errors. Authors are responsible for all statements made in their article, including changes made by the copy editor and authorized by the corresponding author.
The dates of receipt and acceptance will be published for each article. Authors are expected to return manuscripts to the Journal within 15 calendar days after they are sent to them for modifications or for style and copy editing, and to return galley proofs within 72 hours. The total number of "late" days will be added to the submission date at the time of publication.
