General information The European Research Journal (EuRJ) is an international, independent, double-bind peer-reviewed, open access and online publishing journal, which aims to publish papers on all the related areas of basic and clinical 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 EuRJ Executive Editorial Board who discuss the suitability then consider the reviewers’ comments on each submission. The final decision for all submitted manuscripts rests with the Editor-in-Chief. Editorial Board of the European Research Journal complies with the criteria of the International Council of Medical Journal Editors (ICMJE), the World Association of Medical Editors (WAME), and the Committee on Publication Ethics (COPE). The journal is published bimonthly (January, March, May, July, September, and November).

Publishing Principles

1. Original articles, case reports, invited reviews, and letters to the editors in any field of medical sciences published in English only.
2. Articles that were previously unpublished elsewhere and not in the review process in another journal for publication will be accepted.
3. Articles that are approved by the Editorial Board are entitled to be published after at least two relevant Scientific Advisory Board Members' positive opinions. These boards have all privileges to make corrections and abbreviations that are not changing the content of the manuscript.
4. The scientific and legal responsibilities of the article are those of the author.
5. Authors must conform exactly to the research and publication ethics.
6. The copyright of the article is owned by The European Research Journal.

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 http://www.wma.net/e/policy/b3.htm, “Guide for the Care and use of Laboratory Animals” www.nap.edu/catalog/5140.html/), 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 at http://eurj.org/copyright-form/ website 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 submission of the manuscript with correct medical English as well as submission of any figures and tables in the formats specified. Authors should submit their manuscript and accompanying material to the EuRJ via the online Editorial Manager system by logging on https://dergipark.org.tr/journal/325/submission/start and uploading all manuscript files following the instructions are given.

Authorship

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.

Permission

All figures, tables, and text passages that have been previously published require permission from the copyright owner(s) for the EuRJ. All expenses related to obtaining such permission must be borne by the authors. By signing the copyright form, you state that he 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, and graphs as well as 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 recommended font size is 12 point. 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.

Abstracts

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

Keywords

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 in 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

Footnotes may be used to give additional information but 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.

Acknowledgments

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

Table

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 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.

Figures

Each of figure should be added into the main text following references or tables in 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 also in bold type. Do not use any punctuation following the figure number, and do not 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 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

The purpose of proofreading is 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 approval of the editor. 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 as well as of any electronic supplementary material, are the sole responsibility of the authors. No responsibility will be assumed by the EuRJ 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 judges it to be 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 sole responsibility of the authors.
