Guide for Authors

SUBMISSION OF MANUSCRIPTS
Articles must be submitted electronically using the Elsevier Editorial System (EES). EES is a web-based system with full online submission, review and status update capabilities. EES allows you to upload files directly from your computer. You may access EES at http://www.ees.elsevier.com/lfs/ If you are using EES for the first time, you must register before you submit a paper. To do so, please click on "Submit Paper", then "Not Yet Registered", to begin the registration process.

EES SUBMISSION HELP
Contact Elsevier at authorsupport@elsevier.com

Following submission, the article is assigned to either the European or U.S. Office. Neither office accepts hard copy submissions. Specific queries can be directed to lifesci@elsevier.com.

IMPORTANT INFORMATION
1. Submission of a paper will be held to imply that the manuscript contains original unpublished work and is not being submitted for publication elsewhere.
2. Manuscripts submitted under multiple authorship are reviewed on the assumption that all listed authors concur with the submission and that a copy of the final manuscript has been approved by all authors and tacitly or explicitly by the responsible authorities in the laboratories where the work was carried out.
3. It is understood that with submission of this article the authors have complied with the institutional policies governing the humane and ethical treatment of the experimental subjects, and that they are willing to share the original data and materials if so requested.
4. Conflict of Interest/Full Disclosure: In addition to complete contact/address of employer/institutional affiliation for all authors, all other relationships that may be perceived to potentially conflict the objectivity of any author must be fully disclosed in a footnote to the manuscript.

Suggested Referees: To expedite the review process, authors must submit names of 4 - 6 individuals who are qualified to review their work. Include the email address of each potential referee, as much contact information as possible, and why you feel this person is competent to review your work. You should not have collaborated with the suggested reviewers at any time in the past five years. In our effort to enhance global perspective and communication of science, these individuals should be associated with institutions from as many different regions as possible (Europe, North America, Asia, etc.). Exception: Symposium submissions which have been previously reviewed and approved by their Organizing Committee.

FORMATTING INSTRUCTIONS
1. Prepare the text in Microsoft Word in order to prevent conversion errors.
2. Use double line spacing with no paragraph indents.
3. All manuscript pages should be numbered.
4. Use the word-processor's word-wrap feature. Use hard returns only at the end of paragraphs.
5. Do not italicize common Latin terms (i.e., in vivo, in vitro, et al., ad libitum).

ORGANIZATION OF THE MANUSCRIPT
Beginning with the first page, present your manuscript in the order below:
1. Title: First letter capitalized, subsequent letters in lower case. Maximum length 150 characters including spaces. Avoid abbreviations.
2. Name, institutional affiliation and complete address of each author.
3. Author to whom proofs and correspondence should be sent, including name, mailing address, telephone and fax numbers, and e-mail address.
4. Structured abstract of no more than 250 words. The following headings must be used:
Aims:
Main methods:
Key findings:
Significance:
5. Three or more key words for indexing purposes. In addition to key words from the title, please suggest other terms that help define the study. We encourage authors to test the relevance of their key words by using them for a database search and comparing the results with the topic of their own paper.

Headings: Papers must include the major headings Abstract, Introduction, Materials and Methods, Results, Discussion, Conclusion, Acknowledgments, and References. Include subheadings as appropriate. Review articles must contain Abstract and Introduction, with subsequent headings and subheadings as appropriate.

Word limits: In full papers, individual sections should be no longer than Abstract 250 words, Introduction 500 words, Discussion 1500 words, Conclusion 150 words. Materials and Methods and Results sections should be concise but there is no formal word limit. Review articles should be no longer than 8000 words.

Figures, Figure Legends and Tables: Placement of figures and tables will be determined by the printer at the time of publication; do not indicate where they appear in the text. Upload figures and tables where indicated on the Attach Files page of EES. Lettering in figures should be in one of the fonts Arial, Courier, Helvetica, Symbol or Times. Avoid using patterns in histograms/bar graphs. Solid white/gray/black bars are preferred. Do not import figures into the manuscript file. Figures composed of many similar panels should be submitted both in compiled form for review and as separate high-resolution images for production. Tables must be submitted in word processing format, not as images. Figure and table legends are considered part of the manuscript and should appear following References. For information on the preparation of electronic artwork, please see "Artwork instructions" under External link http://www.elsevier.com/artworkinstructions.

Reproduction of Color Photographs: The publisher will publish your color artwork on the Web (e.g. Science Direct and other sites) at no additional cost - regardless of whether the artwork appears in color or black & white in print. For cost of color reproduction in print, you will receive information from Elsevier after your article has been accepted.

Funding Acknowledgment This information must appear under the Acknowledgments heading.

References: References may contain only published works and papers in press. Manuscripts submitted but not yet accepted, unpublished observations and personal communications may be acknowledged (in parentheses) in the text (including year).

When the manuscript has been reviewed, revised if necessary and accepted:

COPYRIGHT AGREEMENT AND OFFPRINT ORDER FORM
A Transfer of Copyright Agreement and an Offprint Order Form will be sent to the corresponding author by Elsevier when the article begins the final production process.

AUTHOR PROOFS
Author proofs will be sent in .pdf format to the corresponding author. Return corrections to the publisher in one communication. Once your corrections have been submitted, it is not possible to incorporate later changes. Our goal is to publish articles in Life Sciences as quickly as possible, thus we request return of corrections to proofs within 24 hours of receipt.

US National Institutes of Health (NIH) voluntary posting ("Public Access") policy.
Elsevier facilitates author response to the NIH voluntary posting request (referred to as the NIH "Public Access Policy"; see External link http://www.nih.gov/about/publicaccess/index.htm) by posting the peer-reviewed author's manuscript directly to PubMed Central on request from the author, 12 months after formal publication. Upon notification from Elsevier of acceptance, we will ask you to confirm via e-mail (by e-mailing us at NIHauthorrequest@elsevier.com) that your work has received NIH funding and that you intend to respond to the NIH policy request, along with your NIH award number to facilitate processing. Upon such confirmation, Elsevier will submit to PubMed Central on your behalf a version of your manuscript that will include your changes made in response to peer-review comments, for posting 12 months after formal publication. This will ensure that you will have responded fully to the NIH request policy. There will be no need for you to post your manuscript directly with PubMed Central, and any such posting is prohibited.
