Instructions for Authors

General information

  • The European Research Journal (EuRJ) is an international double-blind peer-reviewed scientific journal that publishes manuscripts describing both clinical and basic science research in medicine.
  • Manuscripts must describe original data that has not been published previously nor submitted for publication elsewhere.
  • Manuscripts that adhere to the EuRJ submission guidelines and are deemed appropriate for the scope of the journal are sent to two reviewers who are specialists in the field.
  • The members of the Editorial Board who discuss the suitability of then consider the reviewers’ comments each submission.
  • The final decision for all submitted manuscripts rests with the Editor-in-Chief.

Institutional review board/ethics committee approval (IRB)

If a study involves either human subjects, human-derived materials, and/or medical records, authors must include in the Methods section either a statement that an Institutional Review Board (IRB)/Ethics Committee approval has been obtained or a statement that the IRB/Ethics Committee had ruled that approval was not required for the study. When reporting experiments conducted with humans indicate that the procedures were in accordance with ethical standards set forth by the committee that oversees human experimentation. Approval of research protocols by the relevant ethics committee, in accordance with international agreements (Helsinki Declaration of 1975, revised 2002 available at, “Guide for the Care and use of Laboratory Animals”, is required for all experimental, clinical, and drug studies. Patient names, initials, and hospital identification numbers should not be used. Manuscripts reporting the results of experimental investigations conducted with humans must state that the study protocol received institutional review board approval and that the participants provided informed consent.

Copyright transfer

Prusa Medical Publishing retains the copyright to all material published in the EuRJ. Prusa Medical Publishing is not responsible for any legal claims arising from the publication of a manuscript. A Copyright Transfer Agreement form may be downloaded from the Copyright Form link and must be submitted together with the manuscript at the time of initial submission. All authors must sign the form, indicating that they agree to the publication of their manuscript in the EuRJ should their manuscript be accepted. A scanned file (PDF, TIFF, or JPEG) of the signed Copyright Transfer Agreement may be submitted at the time of online submission of the manuscript. The Editorial Office must receive the Copyright Transfer Agreement before any action can be taken regarding the manuscript.

Conflict of interest policy

Authors are required to disclose all conflicts of interest that may have influenced their research or the preparation and writing of their manuscript. Conflicts of interest may include both financial and non-financial relationships. Because it is often difficult to determine whether a conflict of interest exists, Editorial Board requests that all potential conflicts be declared at the time of initial submission of the manuscript on the title page. Other pertinent relationships that may be relevant should be disclosed to the Editor-in-Chief in the cover letter at the time of submission.

Manuscript submission

All manuscripts must conform to the language and writing style of the EuRJ. This includes submitting the manuscript with correct medical English and submitting any figures and tables in the specified formats. Authors should submit their manuscript and accompanying material to the EuRJ via the online Editorial Manager system by logging on and uploading all manuscript files following the instructions given.


All authors should have been directly involved in the work described in the manuscript. Additional contributors to a manuscript, such as professors or others who gave helpful advice or companies that donated material, may be thanked in the Acknowledgments section following the main text. There should be no more than six authors in the case reports. The EuRJ does not permit two or more authors to be “equal contributors” to a manuscript.


All figures, tables, and text passages previously published require permission from the copyright owner(s) for the EuRJ. The authors must bear all expenses related to obtaining such permission. By signing the copyright form, you state that the EuRJ owns the copyright to the material in your article. Permission must be obtained for any material to which the authors do not own the full copyright. No material, such as clinical images or charts, photos, graphs, or images of devices that may have been obtained from their producers, can be published without such permission. To secure the right to publish material that you do not own, contact the holder of the copyright (journal in which it was published, book publishers, or company that developed the instrument) by e-mail describing in detail the material you wish to use and stating that you wish to include that material in your manuscript (including the title The copyright owner will usually reply stating that permission has been granted. A copy of the reply must be forwarded to the EuRJ offices with the number of your manuscript and a description of the materials in question. Most copyright permissions will specify conditions relating to the way in which reference to the permission should be stated. These conditions must be adhered to in full. Otherwise, the permission may be invalid. Note that in some instances, copyright owners may require payment. In these cases, the authors must bear all such costs. As papers cannot be changed once accepted, authors are advised to apply for copyright permission early to prevent the possibility of the paper having to be withdrawn from publication. Note that receiving permission may take up to eight weeks and that the paper cannot be processed for publication before such permission has been granted.

Manuscript preparation

Manuscripts should be created using Microsoft Word and be double-spaced with 2.5 cm margins on all sides. Pages should be numbered consecutively, with consecutive line numbering from the first through the last page, using the automatic numbering function of the software. The recommended font is Times New Roman, and the font size is 12 points. The entire manuscript for a full-length article, including references and tables, should be no more than 6000 words. Do not use field functions. For indenting, use tab stops, not the space bar. For tables, use the table function, not spreadsheets. For equations, use either the equation editor or MathType.


A structured abstract of no more than 250 words is required. The Abstract for all manuscripts except case reports should be divided into Objectives, Methods, Results, and Conclusions.


Keywords are required for indexing and abstracting services. Up to six words should be listed.

Main text

The main text of an original article should be divided into Introduction, Methods, Results, Discussion, and Conclusion sections. Abbreviations must be defined following their first use in the Abstract as well as in the main text and the figures and tables. Only commonly accepted abbreviations should be used. Drug and chemical names should be stated using generic or standard chemical nomenclature. Units of measurement should conform to the International System (SI); however, clinical data may be presented in conventional units where deemed more appropriate.

Headings and subheadings

Use no more than three levels of headings.


Footnotes may be used to give additional information. Still, they should not consist of a reference citation, which is not included in the reference list at the end of the manuscript, and must not contain figures or tables. Footnotes should be numbered consecutively and separately for the title page, the main text, and each table. Footnotes should be indicated by superscript lowercase letters or numbers or by asterisks for significance values and other statistical data. Footnotes should be positioned at the bottom of the page or table in which they appear.


The Acknowledgments section should follow the main text. If data from other published sources are used, the authors must obtain permission as explained above and state full acknowledgment as indicated by the copyright owners. Acknowledgments should also be made of research grants, technicians and colleagues who assisted in the study, individuals or companies who provided materials, and mentors who provided advice and encouragement.


References should be consecutively numbered in order of appearance in the main text and be cited using Arabic numerals in square brackets before the punctuation. Do not cite personal communications, manuscripts in preparation, or other unpublished data as references. They should only include works cited in the text that have been either published or accepted for publication. Journal abbreviations should conform to those used in PUBMED. The style and punctuation of the references should follow the formats outlined in the examples below:

Less than six authors:

1. Duman N, Korkmaz NS, Erol Z. Tissue eosinophilia: a histopathological marker associated with stromal invasion but not histopathological grade in cutaneous squamous neoplasia. Eur Res J 2015;1:88-93.

More than six authors:

2. Budak E, Taymur I, Askin R, Gungor BB, Demirci H, Akgul AI, et al. Relationship between internet addiction, psychopathology and self-esteem among university students. Eur Res J 2015;1:128-35.

Create tables using Microsoft Word so that any corrections or revisions made can be tracked. Tables should be numbered using Arabic numerals and should follow the References section. Each table should have an appropriate title briefly explaining the contents of the table. Tables should always be cited in the text in consecutive numerical order. Identify any previously published material by giving the original source in the form of a reference at the end of the table caption. Footnotes to tables should be indicated by superscript lower-case letters (or asterisks for significance values and other statistical data) and included beneath the table body.


Each figure should be added to the main text following references or tables on separate pages. Number all figures consecutively. For figures with multiple parts, each part should be denoted by lowercase letters (a, b, c, etc.). If you use an appendix in your manuscript containing one or more figures, continue the consecutive numbering of figures from the main text. Do not number the appendix figures “a1, a2, a3, etc.”.

Figure legends

Legends for all figures should be included at the end of the manuscript, beginning with the word “Figure” in bold type, followed by the figure number in bold type. Do not use any punctuation following the figure number or place any punctuation at the end of the legend. The legend should define all elements included in the figure, such as boxes, circles, and arrows. Identify previously published material by giving the original source in the form of a reference citation at the end of the figure legends.

Multicenter clinical trials

The EuRJ welcomes the submission of manuscripts reporting the results of multicenter clinical trials. These manuscripts may be submitted with authorship in one of the following styles:

  • The name of a study group only (collective authorship)
  • The names of no more than five individuals and the name of a study group

In each case, one individual must serve as the corresponding author, and the names of all individuals specifically involved in the preparation of the manuscript should be listed under the heading Writing Committee following the Acknowledgments section. This should be followed by a list of investigators from each institution under the heading Study Group Investigators. Each author and each Writing Committee member must sign the Copyright Transfer Agreement.


Proofreading aims to check for typesetting or conversion errors and the completeness and accuracy of the text, tables, and figures. Substantial changes in content, e.g., new results, corrected values, or changes in title and authorship, are not allowed without the editor's approval. After online publication, further changes can be made only in the form of an Erratum, which will be hyperlinked to the article.

Content responsibility

Content and scientific accuracy of all manuscripts and any electronic supplementary material is the authors' sole responsibility. The EuRJ will assume no responsibility for any legal claim arising from injury and/or damage to persons or property as a matter of product liability, negligence, or other circumstances, nor from any use or operation of any methods, products, instructions, or ideas contained in the published material. No test or procedure should be carried out unless the reader considers it safe. Independent verification of all diagnoses and drug dosages should be performed. Discussions, views, and recommendations regarding medical procedures, choice of drugs, and drug dosages are the authors' sole responsibility.


Although all advertising material in the EuRJ is expected to conform to ethical (medical) standards, their inclusion in this publication does not constitute a guarantee or endorsement by the EuRJ regarding the quality or value of any product or the claim made for it by its manufacturer.

Please make your payment after reading the text below.
• After the article submission process is completed, it will be checked by the journal secretariat whether it is at the minimum level in terms of required forms and writing rules.
• If the article is unsuitable, it will be returned to you for corrections and uploading of missing documents.
• If the article is suitable, you will be notified that the article is suitable by message via Dergipark, and you will be asked to pay the article submission fee and upload the receipt document to the system. After the bank receipt is uploaded to the system, the evaluation process of your article will be started.

The explanation for the article submission fee by the UAK (T.R. Inter-University Board Presidency) is as follows;
“According to the decision taken at the General Assembly of the Council of Higher Education dated 07.03.2019, to be valid for the articles published after 07.03.2019; Journals that charge a fee or additional fee from the author for publication after the acceptance of the article (looting / dubious journals) cannot be used in applications for associate professorship (declaration) since this relationship includes a conflict of interest.”

The submission fee is not subject to the acceptance-rejection condition, is requested to cover the costs incurred during the process, and is not taken for profit. Paying a fee does not mean the article will be accepted and does not increase the chances of acceptance. The article submission fee received before the evaluation within the framework of the UAK statement indicates that our journal is not in the category of predatory journals, and there are no limiting barriers to the use of published articles for UAK applications. Doi numbers are determined immediately for accepted articles after acceptance, and all accepted articles are published early online and open access on our website.

Article submission fee: 100 USD or equivalent TL (Turkish Lira) for original articles, 75 USD or equivalent TL (Turkish Lira) for review and case reports.

Fast-track process: The expected time from submission to the first decision for Fast-track process submissions is 21 days. A Fast-track process does not increase the chance of acceptance of the article. The fee will not be refunded if the article is rejected due to the reviewers' evaluations.
