Basic information
The Brazilian Journal of Medical and Biological Research had the PRINT ISSN ISSN-0100-879X from 1981 to 1997. After 1997, the ISSN of the Brazilian Journal of Medical and Biological Research was modified to ISSN-1414-431X because it became an Electronic Journal. The Journal is published only in electronic version and is an open-access, anonymous peer-reviewed journal published by the Associação Brasileira de Divulgação Científica (ABDC), which is a Federation of Brazilian Scientific Societies (SBBf, SBFTE, SBFis, SBI, SBIC, SBNeC, SBBq, SBBC). The ABDC is a nonprofit organization of scientists committed to making the world's scientific and medical literature a public resource. The Brazilian Journal of Medical and Biological Research is edited at the Campus of Ribeirão Preto, School of Medicine of Ribeirão Preto, University of São Paulo, Ribeirão Preto, SP, Brazil. The publication of the Journal is partially financed by CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico), MCT (Ministério da Ciência e Tecnologia), CAPES (Coordenação de Pessoal de Nivel Superior), ME (Ministério de Educação), and FAPESP (Fundação de Amparo à Pesquisa do Estado de São Paulo). The articles of the Journal are published online, continuously. All research articles published by the Brazilian Journal of Medical and Biological Research since 1997 are available at www.scielo.br/bjmbr and www.bjournal.org. The Brazilian Journal of Medical and Biological Research articles are tracked by PubMed, PubMed Central, ISI Knowledge, and Scopus. The Journal is indexed by all major indexing services, including Web of Knowledge and PubMed. The Journal applies the Creative Commons Attribution License (CC BY) to all works published. Under the CC BY, authors retain ownership of the copyright for their article, but authors allow anyone to download, reuse, reprint, modify, distribute, and/or copy articles in the Brazilian Journal of Medical and Biological Research, as long as the original authors and source are cited. No permission is required from the authors or the publishers. |
Scope and policy
The purpose of the Journal is to publish the results of original experimental research that contribute significantly to knowledge in the 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. Submission of a manuscript to the 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. |

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. Authorship requirements 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.
Author Identification – ORCID BJMBR and Scielo endorse ORCID and requires that all authors provide an ORCID iD when submitting a manuscript. We encourage coauthors to register and use their ORCID as well. We publish all the author’s ORCID iD if the manuscript is accepted. We participate in the auto-update feature implemented by Crossref such that when a paper is published, the authors’ ORCIDs are deposited and subsequently used to update each author’s ORCID record (https://orcid.org). Document signed by ALL authors On submission, you must attach a document* signed by ALL authors of the manuscript informing that he/she:
i) participated in the research that led to the manuscript; THE MANUSCRIPT CANNOT BE SUBMITTED WITHOUT THIS DOCUMENT AS A PDF FILE. *Please upload the document, where indicated, concerning participation in the research, approval of the manuscript submitted, and verification of names, institutions, ORCIDs, and emails signed by EACH author of the manuscript, not by only one author signing for all authors. Signatures must be hand-written by each author. If necessary, individual documents from each author can be uploaded. We do NOT accept computer-generated signatures. There is no special form to be filled out. The document(s) can be a scanned file, photograph, PDF, Word document, or image. The manuscript CANNOT be submitted without this document as a pdf file. Resubmissions Revised manuscripts must be accompanied by a file that includes a detailed point-by-point listing as to how each of the reviewers’ comments has been addressed and describes any other changes made to the manuscript. Authors are invited to upload a revised version of the manuscript in which all new text modifications made should be in black letter highlighted in yellow. This highlighted yellow text to indicate changes will facilitate evaluation of the revisions by the editors and reviewers. Plagiarism BJMBR uses COPE guidelines (powered by iThenticate) to screen submitted content for originality. If plagiarism is detected during the peer review process, the manuscript may be rejected. If plagiarism is detected after publication, we may issue a retraction of the paper, as appropriate. We expect that editors and reviewers will be vigilant in their evaluation of BJMBR submissions and will notify the journal about any plagiarism identified. Publication Charges Publication charges (also referred to as “Article Processing Charges” or APCs) help BJMBR recover the costs of publication—including peer review management, journal production, and online hosting and archiving. BJMBR publishes all content Open Access and makes the content freely available online for researchers and readers to read, distribute, and reuse. The authors are responsible for “publication charges” of all accepted papers. Publication charges will be billed to the Corresponding Author when the paper is accepted. The charge is R$4.000,00/paper for Brazilian authors and US$1,800.00/paper for authors outside Brazil and is independent of the length of the paper. The Journal does not provide reprints to corresponding authors. There is no charge for figures in color. Please contact Reinaldo de Souza (reinaldo.souza@bjournal.com.br) if you have any questions. Cover Letter 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:
Text format
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. 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. Footnotes Text footnotes, if unavoidable, should be numbered consecutively in superscript in the manuscript and written on a separate page following the abstract. Abbreviations 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.
Nomenclature The 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. |
Manuscript categories
Research Articles Full length Paper should clearly state its objective or hypothesis; the experimental design and methods used; 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. 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 Concepts and Comments should provides a platform for readers to present ideas, theories and views. Case Report should have at least one of the following characteristics to be published in the Journal:
Systematic Reviews and Meta-analyses Guidance for reporting of systematic reviews and meta-analyses in the Brazilian Journal of Medical and Biological Research. Search strategy and selection criteria
Authors should check reporting requirements pointed by the Equator Network according to the type of their article. Specifically, clinical trials and systematic reviews should be accompanied by the study´s registration platform and number (eg, with PROSPERO). Review Article Should provide a synthetic and critical analysis of a relevant area and should not be merely a chronological description of the literature. The most important characteristics of Review articles are that they should be critical, synthetic and written by persons who have made significant contributions to the specific research area. The review can be broad or focused, as in a mini-review. We want to protect the Journal from “reports” of the type that are found in the introduction to every dissertation or thesis. Review article are submitted to the normal peer review process.
Overview Should 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.

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. Title Page Title – The title should be as short and informative as possible, should not contain non-standard acronyms or abbreviations, and should not exceed two printed lines.
Example: Please also provide a brief “running title” of up to 60 characters and spaces.
Example: Authors and Affiliations Initials and last name(s) of author(s) (matched with superscript numbers identifying institutions). Institution(s) (Department, Faculty, University, City, State, Country) of each author (in Portuguese if authors are from Brazil).
1Divisão de Animais Peçonhentos, Instituto Vital Brazil, Niterói, RJ, Brasil One of the authors should be designated as the corresponding author. It is the corresponding author’s responsibility to ensure that the author list is accurate and complete. If the article has been submitted on behalf of a consortium, all consortium members and affiliations should be listed after the Acknowledgments. Corresponding author: Name, complete mailing address, including zip code, telephone number, Fax number and E-mail of author to whom correspondence should be sent. Key Words A list of key words or indexing terms (no more than 6) should be included. A capital letter should be used for the first letter of each key word, separated by a semicolon. The Journal recommends the use of medical subject headings of Index Medicus for key words to avoid the use of several synonyms as entry terms in the index for different papers on the same subject. Remember, key words are used by the Scielo Database (see http://www.scielo.br/bjmbr;articles search/subject) to index published articles. Running title This short title, to be used as a page heading, should not exceed 60 letters and spaces. Abstract Since abstracts are published separately by Information Services, they should contain sufficient hard data, to be appreciated by the reader. The Brazilian Journal publishes unstructured abstracts in a single paragraph. The abstract should not exceed 250 words. 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. Please do not include any reference citations in the abstract. If the use of a reference is unavoidable, the full citation should be given within the abstract. Introduction The Introduction should put the focus of the manuscript into a broader context. As you compose the introduction, think of readers who are not experts in this field. This should state the purpose of the investigation and justification for undertaking the research and relationship to other work in the field. An extensive listing or review of the literature should not be used. If there are relevant controversies or disagreements in the field, they should be mentioned so that a non-expert reader can delve into these issues further. The Introduction should conclude with a brief statement of the overall aim of the experiments and a comment about what was achieved. Material and Methods Sufficient information should be provided in the text or by referring to papers in generally available journals to permit the work to be repeated. This section should provide enough detail for reproduction of the findings. Protocols for new methods should be included, but well-established protocols may simply be referenced. We encourage authors to submit, as separate files, detailed protocols for newer or less well-established methods. These will be linked to the article and will be fully accessable. Papers in the area of Clinical Investigation should include a statement indicating that the protocol has been approved by the Hospital Ethics Committee (Hospital with which at least one of the authors is associated) and that written informed consent was obtained from all participants. This information must also be cited in the Material and Methods section of the manuscript. Results The results should be presented clearly and concisely. Tables and figures should be used only when necessary for effective comprehension of the data. The Results section should provide results of all of the experiments that are required to support the conclusions of the paper. There is no specific word limit for this section, but a description of experiments that are peripheral to the main message of the article and that detract from the focus of the article should not be included. The section may be divided into subsections, each with a concise subheading. Large datasets, including raw data, should be submitted as supplementary files; these are published online linked to the article. The Results section should be written in past tense. In some situations, it may be desirable to combine Results and Discussion into a single section. Discussion The purpose of the Discussion is to identify new and relevant results and relate them to existing knowledge. Information given elsewhere in the text, especially in Results, may be cited but all of the results should not be repeated in detail in the Discussion. The Discussion should spell out the major conclusions and interpretations of the work including some explanation of the significance of these conclusions. How do the conclusions affect the existing assumptions and models in the field? How can future research build on these observations? What are the key experiments that must be done? The Discussion should be concise and tightly argued. If warranted, the Results and Discussion may be combined into one section. Acknowledgments When appropriate, briefly acknowledge technical assistance, advice and contributions from colleagues. People who contributed to the work, but do not fit the criteria for authors should be listed in the Acknowledgments, along with their contributions. Donations of animals, cells, or reagents should also be acknowledged You must also ensure that anyone named in the Acknowledgments agrees to being so named. Financial support for the research and fellowships should be acknowledged in this section (agency and grant number). Figures Figures must be submitted in high-resolution version (900 dpi). Please ensure that the files conform to our Guidelines for Figure Preparation when preparing your figures for production. If the manuscript has blots, the authors must submit the original uncropped blots as supplementary material. These uncropped blots must contain the film annotations and the ladder indicating the protein molecular weight. Remember to identify the blots, the bands, and the figure to which they correspond. Preparing figure files for submission The Brazilian Journal of Medical and Biological Research encourages authors to use figures where this will increase the clarity of an article. The use of color figures in articles is free of charge. The following guidelines must be observed when preparing figures. Failure to do so is likely to delay acceptance and publication of the article.
Supported file types The following file formats can be accepted.
Micrographs should be treated like photographs with the following additional guidelines
More information see Guidelines for figures. Tables
References 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 more than three 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, 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.

Cell biology
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. Papers accepted on scientific merit for publication sent to authors for scientific english correction and 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. |
