Manuscript Preparation Guidelines

Please entirely read the instructions discussed below before submitting your manuscript to the journal.

Manuscripts submitted to the journal must meet the aims and scope of the journal and should not be published before or not under consideration elsewhere (in the case of previous oral or poster presentation of the paper at scientific meetings, author should inform the journal). All submitted manuscripts must conform to the research and publication ethics in accordance with the requirements of the ICMJE (International Committee of Medical Journal Editors) and international standards set by COPE (Committee on Publication Ethics). Authors must follow the ethical guidelines presented in Publication Ethics. Authors take full responsibility (ethic, scientific, legal, etc.) for the opinions, findings and discussions presented in the manuscripts as well as resolution of all disputes arising from using copyrighted materials in their manuscripts without proper permission.

All authors must be added to the submission system during manuscript submission. Any request to change authorship (such as adding/deleting authors or modifying order of authors) during revisions must be well justified, and they are subject to editorial approval. No change in authorship is allowed after the manuscript is accepted for publication.

The general rules about the manuscript submissions are given below.

Writing instructions

Submitted manuscripts should be prepared using Microsoft Word program. All manuscripts, figures and pictures must be submitted and all correspondences (manuscript submission, tracking, reviewer reports, revision files, and other forms about publication) are communicated online at:

The journal adopts a double-blind peer reviewing process. In accordance with the double-blind peer-review rules, authors must ensure that (apart from the title page) main manuscript file should contain no clues about the identity of authors and institution where the study was performed. This means that the manuscript should not include authors' names, institutional affiliations or contact information. Also, authors' own works need to be blinded in the references. 

Manuscript files should be arranged as: 1. Title page, 2. abstract, 3. Blinded main manuscript text, 4. Declaration of conflict of interest, 5. References, 6. Table(s), 7. Figure(s) and illustration(s), 8. Figure legend(s).

In addition to the above-mentioned manuscript files, authors are encouraged to provide author contributions and funding information for the manuscript.

For original articles, review articles and case reports, abstract is limited to 250 words, number of keywords is limited to 6, and authors are encouraged to include at most 5 tables and 8 figures. Main text is limited to 10000 words for original articles and 2500 words for case reports (excluding abstract, declaration of conflict of interest, author contributions, funding information, references, tables, figures and legends). Number of references is limited to 60 for original articles and 25 for case reports.

At most one letter to editor may be published in an issue. Letter to editors must start with “To the Editor”, abstract is limited to 75 words, number of keywords is limited to 3, main text is limited to 750 words, number of references is limited to 8. Authors are encouraged to include no tables or figures in letter to editors. 

Preparation of manuscript

Title Page

Title of the article should not exceed 100 characters in original articles and 80 characters in case reports. The first and last names for all contributors designated as author should be written clearly. Subsequently, address of the institution where the study was performed should be written clearly. If the study was previously presented in any scientific meeting, name and date (as day-month-year) of the organization should be written. The name and mailing address of the corresponding author, accompanied by telephone and fax numbers, and e-mail should be written at the bottom of title page.


Abstracts should be presented in a separate sheet. Key words should be listed at the bottom of the abstract page in original articles and should not be more than 5 words. In selecting key words, authors should refer to the Medical Subject Headings (MeSH) list of the Index Medicus. Abbreviations should not be used in the abstract.


It is advised that the text includes the following sections:

Introduction: The matter and purpose of the study is clearly defined.

Materials and Methods: This should include the date and design of the study, the setting, type of participants or materials involved, a clear description of all interventions and comparisons, and the statistical analysis.

Results: Collected data and results of statistical analysis should be outlined in this section.

Discussion: The discussion section should include interpretation of study findings and results should be considered in the context of results in other trials reported in the literature. All written content should be prepared in conformity with grammar and punctuation rules. Avoid abbreviations whenever possible; in case of necessary, it should be given in parentheses when they are first used. References, figures, tables and illustrations should be consecutively numbered in the order in which they have been cited in the text. All measurement units in the text should be used in accordance with international standards for units of measurement.


References should be given double-spaced on a separate page. References should follow the Vancouver-NIH method of reference citation. In this system, references are numbered in consecutive order in which they are first mentioned in the text. All references cited should be listed numerically at the end of the paper (in square brackets). Reference number should be placed at the end of sentence before the period. If there are multiple references number use “,” between them and “-” should be inserted between digits when three or more consecutive references are used (e.g., [1,2], [1-3]).

Prepare citations according to the style used in Index Medicus and the International list of periodical title word abbreviations (ISO 833). All reference citations in the text should appear in the reference list. When there are less than seven authors, each must be listed in the citation. When seven or more authors, list the first three followed by “et al.” after the name of the third author. Using EndNote's bibliographic management tools, you can search bibliographic database, build and organize your reference collection, and then instantly output your bibliography in Vancouver-NIH style and download this style file. Representative examples are as follows:

All abbreviations used in the figures and illustrations should be alphabetically arranged and defined under the footnote. Technique and ratio of magnification for photomicrographs should be indicated. The editorial board has the right to make any revisions on the manuscript unless such changes interfere with the scientific data presented.

Revision after referee report

Final checking
