The Memórias' content is freely accessible to readers and no publication fees are charged to authors. The Memórias do Instituto Oswaldo Cruz has decided to simplify the requirements regarding the format of submitted manuscripts. From now on, all manuscripts may be submitted in any text format as long as the common subdivision of scientific articles are followed, e.g. introduction, materials and methods, results, discussion and references. For Reviews and Perspectives articles, authors may use the sections that best suit the structure and content of the proposed manuscript. All manuscripts should contain, besides the title and abstract, full details of authors and institutions, acknowledgements of any technical or financial assistance as well as state any conflicts of interest. This flexible text format will be used for the initial analysis and peer review. If the manuscript is accepted, authors will be requested to edit the text in accordance with the publication style of the Memorias."
Upon acceptance, the manuscript should be arranged in the following format:
The manuscript should be prepared using standard word processing software and should be printed (font size 12) double-spaced throughout the text, figure captions, and references, with margins of at least 3 cm. The figures should come in the extension tiff, with a minimum resolution of 300 dpi. Tables and legends to figures must be submitted all together in a single file. Figures must be uploaded separately as supplementary file.
Title: with up to 250 characters
Author's names: without titles or graduations
Institutional affiliations: full address of the all authors
Abstracts: Provide an abstract up to 200 words. Abstracts of research articles should be structured into 5 sections as follows: BACKGROUND, OBJECTIVES, METHODS, FINDINGS and MAIN CONCLUSIONS, each section addressing respectively the problem, the aim of the study, the main methodological approach, the most important findings and the conclusions of the study.
Key words: 3-6 items must be provided. Terms from the Medical Subject Headings (Mesh) list of Index Medicus should be used.
Sponsorships: indicate the sources of financial support.
Introduction: should set the purpose of the study, give a brief summary (not a review) of previous relevant work, and state what new advance has been made in the investigation. It should not include data or conclusions from the work being reported.
Materials and Methods: should give full and clear information to permit the study to be repeated by others. Standard techniques need only be referenced. However if a modification has been done in a standard protocol, it must be clearly described.
Ethics: when reporting experiments on human subjects, indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional or regional) and with the Helsinki Declaration of 1975, as revised in 1983. When reporting experiments on animals, indicate whether the institution's or a national research council's guide for, or any national law on the care and use of laboratory animals was followed. In case the research work is making use of natural resources (plant, microorganisms, biodiversity samples) authors must provide a statement that the research work is compliant with the national regulations on this subject.
Results: should be a concise account of the new information discovered, with the least personal judgement. Do not repeat in the text data already described in tables and illustrations.
Discussion: should emphasize the relevance of the new information and relate the new findings to existing knowledge. Only unavoidable citations should be included.
Acknowledgements: should list and give full credit to all of those (apart from authors) who has helped the achievement of the research work (including the funding organizations).
Conflict of Interests: authors must disclose any conflict of interest related to their research work.
Author's contribution: state each author's contribution to the research work.
Figures: presented in tiff format with a minimum of 300 dpi. Photographs must be sharply focused, well contrasted, and if mounted onto a plate, the figures should be numbered consecutively with Arabic numbers. Magnification must be indicated by a line or bar in the figure, and referenced, if necessary in the caption (e.g., bar = 1 mm). Plates and line figures should either fit one column (8 cm) or the full width (16.5 cm) of the page and should be shorter than the page length to allow inclusion of the legend. Letters and numbers on figures should be of a legible size upon reduction or printing. A colour photograph or a related illustration is used in social media of the Journal (Twitter, Instagram and Facebook) for brief information about the content of accepted articles. Authors are invited to submit illustrations with legends from their manuscript for dissemination in social media.
Tables: should supplement, not duplicate, the text and should be numbered with Roman numerals. A short descriptive title should appear above each table, with any explanations or footnotes (identified with a, b, c, etc.) below.
Supplemental material: refers to files which authors supply for publication alongside their article. They should generally be additional pieces to the article that could not be included in the issue, such as appendices, spreadsheets, tables, figures that is impossible to produce within the article. These files will be sent to reviewers for peer review, along with the article’s main files.
We recommend that Supplementary files be in the following format:
- Excel or any spreadsheet should be uploaded in PDF format or provide link to access files
- Supplementary figures with five or more pieces please provide a PDF file with as many figures as possible.
We recommend providing small size files for quick download.
Review/Perspective: articles in “review/perspective” format are accepted only by means of invitations made by the editor or associated editors.
Alternative format: manuscripts may be submitted following the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" produced by the International Committee of Medical Journal Editors also known as the Vancouver Style. In this case, authors should follow the guidelines in the fifth edition (Annals of Internal Medicine 1997; 126: 36-47, or at the website http://www.acponline.org/journals/resource/unifreqr/htm) and will be responsible for modifying the manuscript where it differs from the instructions given here, if the manuscript is accepted for publication.
