Title page
This should list the title of the article. The title should include the study design, for example:
A versus B in the treatment of C: a randomized controlled trial
X is a risk factor for Y: a case control study
The full names, institutional addresses, and e-mail addresses for all authors must be included on the title page. The corresponding author should also be indicated.
Abstract
The abstract of the manuscript should not exceed 350 words and must be structured into separate sections: Background, the context and purpose of the study; Results, the main findings; Conclusions, brief summary and potential implications. Please minimize the use of abbreviations and do not cite references in the abstract. Reviewers, the names of the reviewers in the following format: This article was reviewed by XX, YY and ZZ (NB please state if a reviewer was nominated by a board member thus: XX (nominated by AA)). Trial Registration, if your research article reports the results of a controlled health care intervention, please list your trial registry, along with the unique identifying number, e.g. Trial registration: Current Controlled Trials ISRCTN73824458. Please note that there should be no space between the letters and numbers of your trial registration number.
Background
The background section should be written from the standpoint of researchers without specialist knowledge in that area and must clearly state - and, if helpful, illustrate - the background to the research and its aims. Reports of clinical research should, where appropriate, include a summary of a search of the literature to indicate why this study was necessary and what it aimed to contribute to the field. The section should end with a very brief statement of what is being reported in the article.
Results and Discussion
The Results and Discussion may be combined into a single section or presented separately. Results of statistical analysis should include, where appropriate, relative and absolute risks or risk reductions, and confidence intervals. The results and discussion sections may also be broken into subsections with short, informative headings.
Conclusions
This should state clearly the main conclusions of the research and give a clear explanation of their importance and relevance. Summary illustrations may be included.
Methods
This should include the design of the study, the setting, the type of participants or materials involved, a clear description of all interventions and comparisons, and the type of analysis used, including a power calculation if appropriate.
List of abbreviations
If abbreviations are used in the text either they should be defined in the text where first used, or a list of abbreviations can be provided, which should precede the competing interests and authors' contributions.
Competing interests
A competing interest exists when your interpretation of data or presentation of information may be influenced by your personal or financial relationship with other people or organizations. Authors should disclose any financial competing interests but also any non-financial competing interests that may cause them embarrassment were they to become public after the publication of the manuscript.
Authors are required to complete a declaration of competing interests. All competing interests that are declared will be listed at the end of published articles. Where an author gives no competing interests, the listing will read 'The author(s) declare that they have no competing interests'.
When completing your declaration, please consider the following questions:
Financial competing interests
- In the past five years have you received reimbursements, fees, funding, or salary from an organization that may in any way gain or lose financially from the publication of this manuscript, either now or in the future? Is such an organization financing this manuscript (including the article-processing charge)? If so, please specify.
- Do you hold any stocks or shares in an organization that may in any way gain or lose financially from the publication of this manuscript, either now or in the future? If so, please specify.
- Do you hold or are you currently applying for any patents relating to the content of the manuscript? Have you received reimbursements, fees, funding, or salary from an organization that holds or has applied for patents relating to the content of the manuscript? If so, please specify.
- Do you have any other financial competing interests? If so, please specify.
Non-financial competing interests
Are there any non-financial competing interests (political, personal, religious, ideological, academic, intellectual, commercial or any other) to declare in relation to this manuscript? If so, please specify.
If you are unsure as to whether you, or one your co-authors, has a competing interest please discuss it with the editorial office.
Authors' contributions
In order to give appropriate credit to each author of a paper, the individual contributions of authors to the manuscript should be specified in this section.
An "author" is generally considered to be someone who has made substantive intellectual contributions to a published study. To qualify as an author one should 1) have made substantial contributions to conception and design, or acquisition of data, or analysis and interpretation of data; 2) have been involved in drafting the manuscript or revising it critically for important intellectual content; and 3) have given final approval of the version to be published. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. Acquisition of funding, collection of data, or general supervision of the research group, alone, does not justify authorship.
We suggest the following kind of format (please use initials to refer to each author's contribution): AB carried out the molecular genetic studies, participated in the sequence alignment and drafted the manuscript. JY carried out the immunoassays. MT participated in the sequence alignment. ES participated in the design of the study and performed the statistical analysis. FG conceived of the study, and participated in its design and coordination and helped to draft the manuscript. All authors read and approved the final manuscript.
All contributors who do not meet the criteria for authorship should be listed in an acknowledgements section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chair who provided only general support.
Reviewers' comments
Please insert each reviewer's name followed by their comments here. If the reviewer has not returned their comments, please state: 'This reviewer provided no comments for publication.'.
Acknowledgements
Please acknowledge anyone who contributed towards the study by making substantial contributions to conception, design, acquisition of data, or analysis and interpretation of data, or who was involved in drafting the manuscript or revising it critically for important intellectual content, but who does not meet the criteria for authorship. Please also include their source(s) of funding. Please also acknowledge anyone who contributed materials essential for the study.
The role of a medical writer must be included in the acknowledgements section, including their source(s) of funding.
Authors should obtain permission to acknowledge from all those mentioned in the Acknowledgements.
Please list the source(s) of funding for the study, for each author, and for the manuscript preparation in the acknowledgements section. Authors must describe the role of the funding body, if any, in study design; in the collection, analysis, and interpretation of data; in the writing of the manuscript; and in the decision to submit the manuscript for publication.
References
All references must be numbered consecutively, in square brackets, in the order in which they are cited in the text, followed by any in tables or legends. Reference citations should not appear in titles or headings. Each reference must have an individual reference number. Please avoid excessive referencing. If automatic numbering systems are used, the reference numbers must be finalized and the bibliography must be fully formatted before submission.
Only articles and abstracts that have been published or are in press, or are available through public e-print/preprint servers, may be cited; unpublished abstracts, unpublished data and personal communications should not be included in the reference list, but may be included in the text. Notes/footnotes are not allowed. Obtaining permission to quote personal communications and unpublished data from the cited author(s) is the responsibility of the author. Journal abbreviations follow Index Medicus/MEDLINE. Citations in the reference list should contain all named authors, regardless of how many there are.
We encourage authors to use a recent version of EndNote (version 5 and above) or Reference Manager (version 10) when formatting their reference list, as this allows references to be automatically extracted. Authors submitting articles in EndNote 5 or higher or Reference Manager 10 format will save ?0 on the ?50 (€1105, US$1480) article processing charge. In order to obtain this discount, you should upload the manuscript file containing your EndNote or Reference Manager-formatted bibliography as a .doc file. Please ensure you do not convert to another format (e.g. RTF or PDF). On upload, the discount will be automatically granted and you will receive a confirmation on-screen and by email. You will also be able to preview an HTML version of the extracted references during submission, and we urge authors to check this. EndNote or Reference Manager users should also make sure that any changes made to the reference list are done within their reference management program, rather than by manually editing the formatted bibliography. This is because manually introduced changes will not be picked up in the automatically extracted list.
Further details about EndNote and Reference Manager are available on the BioMed Central site, including information about how to upgrade.
Style files that conform to the BioMed Central style are available for EndNote and Reference Manager. Users of other reference management programs should be able to select other journal styles that output a numeric list styled similarly to the guide below.
Examples of the Biology Direct reference style are shown below. Please take care to follow the reference style precisely; references not in the correct style may be retyped, necessitating tedious proofreading.
Links
Web links and URLs should be included in the reference list. They should be provided in full, including both the title of the site and the URL, in the following format: The Mouse Tumor Biology Database [http://tumor.informatics.jax.org/cancer_links.html]

Microsoft Word template
Although we can accept manuscripts prepared as Microsoft Word, Word Perfect, RTF or PDF files, we have designed a Microsoft Word template that can be used to generate a standard style and format for your article. It can be used if you have not yet started to write your paper, or if it is already written and needs to be put into Biology Direct style.
Download the template (Mac and Windows compatible Word 1998/2000) from our site, and save it to your hard drive. Double click the template to open it.
How to use the Biology Direct template
The template consists of a standard set of headings that make up a Biology Direct Research manuscript, along with dummy fragments of body text. Follow these steps to create your manuscript in the standard format:
- Replace the dummy text for Title, Author details, Institutional affiliations, and the other sections of the manuscript with your own text (either by entering the text directly or by cutting and pasting from your own manuscript document).
- If there are sections which you do not need, delete them (but check the rest of the Instructions for Authors to see which sections are compulsory).
- If you need an additional copy of a heading (e.g. for additional figure legends) just copy and paste.
- For the references, you may either manually enter the references using the reference style given, or use bibliographic software to insert them automatically. We provide style files for End Note and Reference Manager.
For extra convenience, you can use the template as one of your standard Word templates. To do this, put a copy of the template file in Word's 'Templates' folder, normally C:\Program Files\Microsoft Office\Templates on a PC. The next time you create a new document in Word using the File menu, the template will appear as one of the available choices for a new document.
Note - From version 6, EndNote includes a full set of structured article templates for BioMed Central journals. Users of EndNote are encouraged to upgrade if necessary and make use of these templates. More information is available here.
