Submission checklist

  • Make sure that all authors are informed and confirm their status of authorship.
  • Make sure that a cover letter is submitted as a separate file. The statement that the manuscript is not being considered for publications by another journal should be added in this file.
  • The main manuscript should be anonymized, and should not contain information that may reveal the name of authors or institutions.
  • Tables and figures should be included within the main manuscript file and placed at the first time it is referred at the body of the manuscript.
  • Manuscript title page submitted in a separate file: This contains paper title, name of the authors with their clear affiliations. Name of the corresponding author including the affiliation name, place address, email should be added within this file.
  • Please include additional documents as attachments: Ethical approval letter, conflict of interest forms.

Peer review

This journal operates a double-blind review process. All contributions will be initially assessed by the editor for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. The Editor's decision is final.

Double-blind review

This journal uses a double-blind review, which means the identities of the authors are concealed from the reviewers, and vice versa.


Manuscript preparation

Abstract and Keywords: The abstract should consist of not more than 250 words. A structured abstract is more acceptable. For original articles, results and conclusions should be included. Below the abstract, provide no more than 5 keywords. Information on the level of evidence of the publications should be added just after the keywords.

Introduction: The authors should provide only relevant information. An extensive review of a subject should be avoided. Do not include results or conclusions of the study. State the purpose of the study clearly.

Material and method: The authors should describe the design of the study, specify the selection of subjects or study groups. Describe the methods, apparatus and procedures in sufficient detail. The author should describe the statistical methods used with adequate details to enable the reader to verify the reported outcome.

The authors should indicate whether such ethical approval has been procured. When reporting experiments on human subjects, indicate whether the procedures followed were under the ethical standards of the responsible committee on human experimentation with the Declaration of Helsinki. For Animal experiments, the author should indicate whether the institution or a national research ethical for the animal has been followed.

Results: The author presents the important findings of the research in this section. The results can be supplemented with tables or illustrations.  Do not repeat all the data contained in the tables or illustrations. The table or illustration should be embedded in the body of the text which they are the first time referred.

Discussion: Avoid repeating the findings of the research which has been mentioned in the results section. Emphasize only important findings with their implications and limitations. Relate the observations to other relevant studies. Avoid statements that are not completely supported by the results of the study. Whenever recommendations for treatment are made, the patient's groups and applicable conditions must be carefully defined. Limitation of the study should be described in the last paragraph of this section.

Conclusion: The conclusions should be correlated with the aim (s) of the study. All conclusions must be supported by the results of the study. Avoid overconfidently claiming priority to work that has not been completed.


The “Roman numerals” should be used for numbering tables (e.g. Table I, Table II). Attach each table inside the body text near the first time it is referred. The content of a table should be clearly explained so that it is comprehensive without reference to the text. The use of tables should be kept to a minimum, simple, and easy to understand.

Illustrations / Figures

The “Arabic numerals” should be used for numbering illustrations followed by capital alphabetic, and present them as “Figures” (e.g. Figure 1A, Figure 1B). Attach each figure inside the body text of the blinded manuscript near the first time it is referred.

Higher resolution images (300 DPI or higher) should also be submitted as separate files (JPEG or TIFF) and named according to figure numbers. Do not use patients’ names, initials, or hospital numbers, especially in illustrative material. Please make sure that the identity of the patients is not disclosed.


  • References must be placed at the end of the manuscript. Please use recent references as much as possible (less than 10 years).
  • The responsibility for the accuracy of references lies with the respective authors.
  • Present references in Vancouver style.
  • Number the references in the order in which they first appear in the text and identify the reference numbers in the text in Superscript in “Arabic numerals”.
  • List the first 6 authors followed by “et al”. 
  • Journal titles should be abbreviated according to Index Medicus.

Please pay attention to the style of references as follows:
