Laboratory Animals, or equivalent). For studies involving human subjects, authors should obtain express permission from subjects and respect
their privacy. Confirmation that approval has been sought and obtained should be included in the manuscript where applicable. Experiments

PREPARATION OF MANUSCRIPT (Click to submit a manuscript online)

All manuscripts should be written in standard grammatical English using computer software (Franklin Gothic Book normal font, size 12, with
single spacing between lines) and should be saved as single DOC (Word) file. Main Research Articles and Brief Communications will follow a
similar format as outlined below while Review Articles will follow a variation on this (see below).

Main Research Articles are defined as being a substantial novel research study discussing the investigation of a clear hypothesis or research
question with appropriate methodologies (the use of more than one approach is encouraged) and adequately powered studies and sample
sizes. Noting the relevant sections (see below) there is no word limit on manuscripts of this type except for the Abstract which should be a single
unreferenced paragraph and no more than 350 words. There are no limits on the number of display items (tables and/or figures) although
authors should try to be concise and only include the most pertinent information. There are no supplementary tables or figures and every effort
should be made to include these in the main manuscript or alternatively reference should be made in the appropriate locations of the
manuscripts that such information will be available on request from the
corresponding authors. There is no limit on the number of references.

Brief Communications are a format that accommodates the reporting of high quality completed smaller scale studies. This format is not for the
reporting of preliminary or incomplete findings and the review process is equally rigorous as that for Main Articles. The sections of a Brief
Communication follow those of Main Articles (see below) and there should not be additional sub-headings within these sections.

Review articles have a flexible format, are not of restricted length or reference number. Submissions of reviews must follow that of Main
Research Articles (see below) with the exception that appropriate headings be included for the main text of the manuscript.

Layout requirements for submissions of Main Research Articles, Review Articles, Brief Communications and Case Report:

1.        Cover letter
2.        Title page
3.        Abstract and keywords
4.        Main text
5.        Acknowledgements, if any
6         Declaration of conflicts of interest, if any
7.        References
8.        Tables, if any
9.        Figure legends, if any
10.      Figures, if any

All sections must be submitted in a single MS Word file including tables (no image tables) with all high resolution figures embedded at the end
of the Word file of the manuscript.

Cover Letter

The cover letter should include name, degree, address, telephone, fax and email of the corresponding author. A statement that all authors have
contributed to, read and approved the final manuscript for submission should be included if there are multiple authors. Any editorial or financial
conflict of interest (e.g., consultancy, stock ownership, equity interests, patent or licensing agreements) should be clearly disclosed in the cover
letter. The disclosure statement must be submitted upon the acceptance. The cover letter should also be used to provide up the relevant details
of 4 potential reviewers and 2 non-reviewers for your manuscript giving appropriate explanations for the latter. Finally, if this submission is
following the solicitation or invitation of an Editorial Board member please state by whom.

Title Page

1.        A concise title;
2.        First name, middle initial, and last name of each author;
3.        Name of the department and institutional affiliation of each author.
4.        The official academic email address of each author.(*)
5.        A short running title.
6.        Corresponding author name and contact information including e-mail and phone number.
7.        Acknowledgement including funding information (agency ann grant number).

(*) AJDD will only use the email address of the designated corresponding author in the final published manuscript but will use all email
addresses supplied to copy in all authors as additional email respondents to the correspondences we routinely send to acknowledge receipt of
manuscripts, and final decisions made on submitted manuscripts. AJDD would also like, unless otherwise directed in the manuscript covering
letter, to use these contact details to announce the contents lists of future issues of AJDD and its sister journals! At no stage will AJDD sell such
email lists to parties external to the
e-Century Publishing Corporation.
