Complete and detailed Guidelines for Authors

The authors are reponsible for "publication charges" of all accepted papers. Publication charges will be billed to the Corresponding Author when paper is accepted.

For papers submitted after January 5, 2009, the charge is R$1.250,00/paper for Brazilian authors and US$550,00/paper for authors outside Brazil and is independent of the length of the paper.

The Journal does not provide reprints to corresponding authors. They will receive a CD containing the issue in which the paper is published. There is no charge for figures in color.

Please contact Reinaldo de Souza (bjournal@fmrp.usp.br) if you have any questions.

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.

Complete the form for submission at http://www.bjournal.com.br/ and send the manuscript as an attachment to the cover letter to bjournal@fmrp.usp.br or bjournal@terra.com.br.

The cover letter should contain the following information:

• Title of article.
• Name(s) of all author(s).
• A statement signed by the corresponding author that written permission has been obtained from all persons named in the acknowledgements should be sent by fax to +55-16-3633-3825 or 3630-2778.
• If a version of the manuscript has been previously submitted for publication to another journal, include comments from the peer reviewers and indicate how the authors have responded to these comments.
• 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.
• Animal experimentation should be carried out according to institutional guidelines for experimental use of animals.
• The authors should obtain written permission to reproduce figures and tables from other sources.

Most of the provisions of the United States Copyright Act of 1976 became effective on Jan. 1, 1978. All published manuscripts become the permanent property of the Brazilian Journal of Medical and Biological Research and may not be republished without written permission from the Brazilian Journal.

Full-length Paper.

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 section placing the results in the context of published literature. A full-length paper should contain:

• an abstract of no more than 250 words
• no more than 6 key words
• a running title to be used as a page heading, which should not exceed 60 letters and spaces
• the text should be divided into separate sections (Introduction, Material and Methods, Results, Discussion), without a separate section for conclusions
• no more than 40 references (no exceptions will be made)
• authors should state in the cover letter that the manuscript is intended to be a full-length paper

Short Communication. 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. A short communication should contain:

• an abstract of no more than 250 words
• no more than 6 key words
• a running title to be used as a page heading, which should not exceed 60 letters and spaces
• text not exceeding 12 double-spaced typed pages of 23 lines each
• a maximum of 2 figures or tables (or one of each)
• no more than 20 references (no exceptions will be made)
• the text should be divided into separate sections (Introduction, Material and Methods, Results, Discussion), without a separate section for conclusions
• authors should state in the cover letter that the manuscript is intended to be a short communication

Review Article. 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. A minireview and review article should contain:

• an abstract of 250 words or less
• no more than 6 key words
• a running title to be used as a page heading, which should not exceed 60 letters and spaces
• no more than 60 references (no exceptions will be made)
• the text may be divided into sections with appropriate titles and subtitles
• authors should state in the cover letter that the manuscript is intended to be a review article

Concepts and Comments.The Concepts and Comments section provides a platform for readers to present ideas, theories and views. Contributions should be presented with an abstract, 6 key words, a running title, no more than 20 references and up to 2 tables or figures.

Case Report. A case report should have at least one of the following characteristics to be published in the Journal:

• special interest to the clinical research community
• a rare case that is particularly useful to demonstrate a mechanism or a difficulty in diagnosis
• new diagnostic method
• new or modified treatment
• a text that demonstrates relevant findings and is well documented and without ambiguity.

Overviews. 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 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.

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:

• Papers should describe the separation of the crude material into fractions (not necessarily into homogeneous materials) with the fractions containing biological activity identified clearly in the separation scheme. Phytochemical studies should be accompanied by biological tests. A survey of pharmacological activity of plant extracts or teas will not be considered for publication.
• In addition to the demonstration of activity in one or more biological system, experiments must be performed attempting to provide information concerning the mechanism(s) of action of the substance(s) being tested.
• Sufficient experimental information must be provided to permit repetition of the preparation of fractions and the bioassay used.
• Sources should be identified completely, and, if plant material, a specimen should be classified by an expert and deposited in a local botanical garden, university or research institute. The name and institution of the person who classified the plant and the number of the voucher under which it was deposited should be provided in the Material and Methods section.
• The Journal does not publish toxicological studies.

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.

• Conceived, planned and carried out the experiments that led to the paper or interpreted the data it presents, or both.
• Wrote the paper, or reviewed successive versions.
• Approved the final version.
• Holding positions of administrative leadership, contributing patients, and collecting and assembling data, however important to the research, are not by themselves criteria for authorship. Other persons who have made substantial, direct contributions to the work but cannot be considered authors should be cited in the acknowledgment section, with their permission, and a description of their specific contributions to the research should be given.

Manuscripts should be submitted in English. Authors are requested to use American spelling, except, of course, for references whose titles should appear exactly as published. Guidance on grammar, punctuation, and scientific writing can be found in the following sources: Scientific Style and Format: The CSE Manual for Authors, Editors, and Publishers. 7th edn. Rockefeller University Press, Reston, 2006; Medical Style and Format. Huth EJ (Editor). ISI Press, Philadelphia, 1987, Marketed by Williams & Wilkins, Baltimore, MD. 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).

Text Format The text of a manuscript can only be accepted as a Microsoft Word file created with MS Word 6.5 or a later version as a "doc" or "rtf" document.

• Submit the manuscript by e-mail, in letter size format (8.5 x 11"), with wide margins of at least 1 inch (2.54 cm), 23 lines per page, which contains approximately 2,156 characters, including spaces.
• Use a serif font, preferably Times New Roman, 12 point type, including title page, abstract, text, acknowledgments, references, figure legends, and tables. Each page should contain the page number in the upper right-hand corner starting with the title page as page 1.
• Report all measurements in Système International, SI (http://physics.nist.gov/cuu/Units) and standard units where applicable (see below).
• Do not use abbreviations in the title or abstract and limit their use in the text.
• The length of the manuscript and the number of tables and figures must be kept to a minimum.
• Ensure that all references are cited in the text.
• Generic names must be used for all drugs. Instruments may be referred to by proprietary name; the name and country or electronic address of the manufacturer should be given in parentheses in the text.

Footnotes. Text footnotes, if unavoidable, should be numbered consecutively in superscript in the manuscript and written on a separate page following the abstract.

Headings in text

• Position all headings flush with the left margin.
• Keep headings short (three or four words).
• Use only three types of headings in the text. Clearly indicate the type of level of headings by using the following typographic conventions.
  • First-level: Only the 1^st letter of the 1^st word is capitalized, font size 11, bold type.
  • Second-level: Only the 1^st letter of the 1^st word is capitalized, font size 9, bold type.
  • Third-level: Only the 1^st letter of the 1^st word is capitalized, italic type.

Abbreviations and symbols

• Explain all abbreviations in the text, figure and table legends when they first appear. Keep the number of abbreviations to a minimum.
• Do not explain abbreviations for units of measurement [3 mL, not 3 milliliters (mL)] or standard scientific symbols [Na, not sodium (Na)].
• Abbreviate long names of chemical substances and terms for therapeutic combinations. Abbreviate names of tests and procedures that are better known by their abbreviations than by the full name (VDRL test, SMA-12).
• Use abbreviations in figures and tables to save space, but they must be defined in the legend.

Units. The Système International (SI) (http://physics.nist.gov/cuu/Units) in metric units is used for units and abbreviations of units. Examples:

• s for second
• min for minute
• h for hour
• L for liter
• m for meter
• kDa for mass in kilodaltons
• 5 mM rather than 5 x 10-3 M or 0.005 M

Title page.  

The title page should contain the following information:

• 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.
• 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).
• Acknowledgment of research grants and fellowships (agency and grant number).
• Name, complete mailing address, including zip code, telephone number, fax number and e-mail of author to whom correspondence should be sent.

Running Title. This short title, to be used as a page heading, should not exceed 60 letters and spaces.

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 the article.

Abstract

• Since abstracts are published separately by Information Services, they should contain sufficient hard data to be evaluated by the reader.
• The abstract should briefly and clearly present the problem, experimental approach, new results as quantitative data if possible, and conclusions.
• The abstract should not exceed 250 words and should be written as a single paragraph double-spaced on a separate page following the title page.
• Abbreviations should be kept to a minimum and must be defined at first citation.
• If the use of a reference is unavoidable, the full citation should be given within the abstract.
• Note that the Brazilian Journal publishes unstructured abstracts.
• Please see <http://www.bjournal.com.br/Instructions/html/writing_a_good_abstract.htm> for suggestions on writing a good abstract.

Introduction. This should state the purpose of the investigation, relationship to other work in the field, and justification for undertaking the research. An extensive listing or review of the literature is not recommended.

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 and to determine the suitability of the methods used for the objectives of the research.

Results. The results should be presented clearly and concisely. Tables and figures should be used only when necessary for effective comprehension of the data. In some situations, it may be desirable to combine Results and Discussion in a single section.

Discussion. The purpose of the Discussion is to interpret the results and relate them to existing knowledge. Information given elsewhere in the text, especially in Results, may be cited but not repeated in detail in the Discussion.

Acknowledgments. When appropriate, briefly acknowledge technical assistance, advice and contributions from colleagues to the research. Financial support for the research and fellowships should be acknowledged on the title page.

• We cannot accept some application programs, such as Microsoft Office (Access), Corel Perfect Office (WordPerfect, Quattro Pro, Presentations), Lotus SmartSuite (Freelance Graphics, 1-2-3, Approach, WordPro), Harvard Graphics and SigmaPlot because they are not intended for the high resolution imaging. Graphs created in one of these programs and saved as "jpg" or similar also cannot be accepted.
• Photomicrographs should include stain and magnification data at the end of the legend for each part of the figure. A magnification bar should be added to each photomicrograph. If no scale marker appears in the figure, the original magnification should be reported in the legend.
• Figure legends should be typed double-spaced consecutively on a separate page.
• Figure legends must have a descriptive title and all explanatory information so that the figure is understandable without referring to the text.
• All abbreviations and symbols must be defined in the legend, even if they are explained in the text.
• Adapting/reproducing figures and relevant permissions. Acknowledgment of original sources of copied material should be given.
• Color figures should be in RGB, at least 300 dpi. There is no charge for color figures.
• Check figures carefully before submission to ensure that proper versions are being sent and that there are no labeling errors.
• All figures with the exception of line drawings will be published exactly as the author sent them to the Journal and the reproduction quality will be the total responsibility of the author.

Authors are responsible for the accuracy and completeness of their references and for correct text citation. When possible, references in English should be cited. The reference list must be numbered consecutively in the order in which the references are first cited in the text, using arabic numerals, and must be typed double-spaced on separate sheets. In the text, citation of two or more references, within parentheses, should be separated by a comma without a space (1,5,7); three or more consecutive references should be separated by a hyphen (4-9).
