Information for Authors


Instructions before submitting an article


Study Conduct and Policies 

The process of reviewing and assessing manuscripts, including for ethical guidelines and plagiarism/duplicate publication and study misconduct, should conform to the ethical guidelines specified in the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals, which were established by the International Committee of Medical Journal Editors (ICMJE).


Ethics in publishing 

The work described in your article must have been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans EU Directive 2010/63/EU for animal experiments Uniform Requirements for manuscripts submitted to Biomedical journals . This must be stated at an appropriate point in the article.


Declaration of interest 

According to The International Committee of Medical Journal Editors, authors must report any financial and personal relationships with other people or organizations that could unduly affect their work. Examples of possible competing interests include employment, consulting services, share ownership, fees, paid expertise, patent applications/registrations, and grants or other financings. If there is no conflict of interest, on the title page please state: “The authors declare no conflict of interest.” If there is no conflict of interest, on the title page please state: “The authors declare no conflict of interest.”


Statement of informed consent and institutional review board approval

Human studies must conform to current ethical standards and should be approved by the appropriate Institutional Review Board (IRB). A statement concerning IRB approval, reference number, and consent procedures must appear in the Methods section. Any systematic data-gathering effort from patients or other participants (students, nurses etc.) must be approved by an IRB or adhere to appropriate local/national regulations. A copy of the approved RBI should be submitted to the journal at the same time as the article.



According to the guidelines of the ICMJE, authorship credit must be based on 1) substantial contributions to the concept and design, or acquisition of data, or analysis and interpretation of data; 2) drafting the work or revising it critically for important intellectual content; 3) final approval of the version to be published; and 4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. 

All authors should meet the above four conditions. For original articles, the specific contributions of each author must be described, and this information will be published in the Author Contributions section. After the initial submission of a manuscript, any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. 


Changes to authorship

The authors must carefully consider the list and order of authors before submitting their article. Any changes to the list of authors after the initial submission should be approved by all authors, including all authors who have been removed from the list. The corresponding author should act as a point of contact between the editor and the other authors and should keep co-authors informed and involve them in major decisions about the publication.



All submitted articles must be original and may not be reviewed at the same time by other scientific journals for publication. Publication in another scientific journal of any part of the accepted paper isn’t allowed without the approval of the Editorial Board. Submitted articles are reviewing using appropriate software for possible plagiarism or duplication.


English Language

To facilitate proper peer-reviewing of your manuscript, it is essential that it is submitted in grammatically correct English (American or British usage is accepted, but not a mixture of these). If you are not a native English speaker, we recommend that you have your manuscript professionally edited before submission or read by a native English-speaking colleague. Professional editing will enable reviewers and future readers to more easily read and assess the content of submitted manuscripts. If the English version of your article has been edited by a professional service, please submit the certificate of language editing at the same time as your manuscript as an additional file. If your article is not written in a quality literary English, the NES editors will not consider your article for further review and possible publication in the NES. In that case, your article will be rejected immediately at the initial assessment stage.


Considerations specific to types of research designs

The journal editors recommend that authors adhere to recognized reporting guidelines relevant to the research design used in their manuscripts. These are not quality assessment frameworks and your study need not meet all the criteria implied in the reporting guideline to be worthy of publication in the journal.


Reporting guidelines endorsed by the journal are listed below:
