Ethics in publishing

Please see our information pages on Ethics in publishing and Ethical guidelines for journal publication.

Human and animal rights

If the work involves the use of human subjects, the author should ensure that the work described has been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans; Uniform Requirements for manuscripts submitted to Biomedical journals. Authors should include a statement in the manuscript that informed consent was obtained for experimentation with human subjects. The privacy rights of human subjects must always be observed.

All animal experiments should comply with the ARRIVE guidelines and should be carried out in accordance with the U.K. Animals (Scientific Procedures) Act, 1986 and associated guidelines, EU Directive 2010/63/EU for animal experiments, or the National Institutes of Health guide for the care and use of Laboratory animals (NIH Publications No. 8023, revised 1978) and the authors should clearly indicate in the manuscript that such guidelines have been followed.

Declaration of interest

All authors are requested to disclose any actual or potential conflict of interest including any financial, personal or other relationships with other people or organizations within three years of beginning the submitted work that could inappropriately influence, or be perceived to influence, their work. More information.

Disclosure of conflicts of interest

A conflict of interest occurs when an individuals objectivity is potentially compromised by a desire for financial gain, prominence, professional advancement or a successful outcome. ASJSUR Editors strive to ensure that what is published in the Journal is as balanced, objective and evidence-based as possible. Since it can be difficult to distinguish between an actual conflict of interest and a perceived conflict of interest, the Journal requires authors to disclose all and any potential conflicts of interest.
Conflicts of interest may be financial or non-financial. Financial conflicts include financial relationships such as honoraria; educational grants; participation in speakers bureaus; membership, employment, consultancies, stock ownership, or other equity interest; expert testimony or patent-licensing arrangements. Non-financial conflicts include personal or professional relationships, affiliations, academic competition, intellectual passion, knowledge or beliefs that might affect objectivity.
Please ensure that the name of each author listed in your manuscript appears in either Section I or Section II on page 2 of the ASJSUR Authorship & Conflicts of Interest Statement form (an authors name cannot appear in both Section I and Section II of the form).

Submission declaration

Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint, see 'Multiple, redundant or concurrent publication' section of our ethics policy for more information), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.

Reporting Clinical Trials

All randomized controlled trials submitted for publication should include a completed Consolidated Standards of Reporting Trials (CONSORT) flow chart (available at This Journal has adopted theproposal from the International Committee of Medical Journal Editors (ICMJE) that require, as a condition of consideration for publication of clinical trials, registration in a public trials registry. Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) do not require registration.Further information can be found at


All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted.

Changes to Authorship

This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts. Before the accepted manuscript is published online, requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include:

(i) the reason the name should be added or removed, or the author names rearranged; and

(ii) an updated Authorship & Conflicts of Interest Statement with signatures from all authors that they agree with the addition, removal or rearrangement.

In the case of addition or removal of author names, this must include confirmation from the author(s) being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedures as described above.

Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) online publication of the accepted manuscript is suspended until authorship has been agreed. After the accepted manuscript is published online, any requests to add, remove, or rearrange author names in an article will follow the same policies as detailed above and result in a corrigendum.

Reporting clinical trials
Randomized controlled trials should be presented according to the CONSORT guidelines. At manuscript submission, authors must provide the CONSORT checklist accompanied by a flow diagram that illustrates the progress of patients through the trial, including recruitment, enrollment, randomization, withdrawal and completion, and a detailed description of the randomization procedure. The CONSORT checklist and template flow diagram are available online.


Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (see more information on this). An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.

The Editorial and Peer Review Process

As a general rule, the receipt of a manuscript will beacknowledged within 2 weeks of submission, and authorswill be provided with a manuscript reference number for future correspondence. If such an acknowledgment is not received in a reasonable period of time,the author should contact the Editorial Office.

Submissions are reviewed by the Editorial Office toensure that it contains all parts. The Editorial Office willnot accept a submission if the author has not suppliedall parts of the manuscript and supporting documents asoutlined in these instructions.

Manuscripts are then forwarded to the Editor-in-Chief, who makes an initial assessment of it. If the manuscriptdoes not appear to be of sufficient merit or isnot appropriate for the Journal, then the manuscriptwill be rejected without review. Rejected manuscriptswill not be returned to authors unless requested.

Manuscripts that appear meritorious and appropriatefor the Journal are reviewed by at least two EditorialBoard members or expert consultants assigned by theEditor-in-Chief. The results of the peer reviews are thendiscussed in a committee meeting with the AssociateEditors. Authors are usually notified within 10 weeks ofwhether the submitted article is accepted for publication,rejected, or subject to revision before acceptance.However, do note that delays are sometimes unavoidable.

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 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. More information on types of peer review.

*The name of each author should be written with thefamily name last, e.g., Jing-Lin Chang. Authorship is restrictedonly to direct participants who have contributedsignificantly to the work.

Abstracts and Keywords

Abstracts should be no more than 250 words in length.Abstracts for Original Articles should be structured, with the section headings: Background/Objective, Methods,Results, Conclusion. Abstracts for Case Reports are unstructured,but should include the significance and purpose of the case presentation, the diagnostic methods of the case, the key data, and brief comments and suggestions with regard to the case. Abstracts for Review Articles are also unstructured. For all article categories(except Letters to the Editor), 3-5 relevant keywords should be provided in alphabetical order.

Main Text

The text for Original Articles should be organized intosections as follows: Introduction, Methods, Results,Discussion. Sections for Case Reports are: Introduction,Case Report, Discussion. The text for Review Articlesshould be divided into logical sections with appropriateheadings. Each section should begin on a new page.

Where a term/definition will be continually referred to,it must be written in full when it first appears in thetext, followed by the subsequent abbreviation in parentheses.Thereafter, the abbreviation may be used. Anabbreviation should not be first defined in any sectionheading; if an abbreviation has previously been defined in the text, then the abbreviation may be used in a subsequentsection heading. Restrict the number of abbreviationsto those that are absolutely necessary.

Numbers that begin a sentence or those that are less than 10 should be spelled out using letters. Centuries and decades should be spelled out, e.g., the Eighties or nineteenth century. Laboratory parameters, time, temperature, length, area, mass, and volume should be expressed using digits.

Système International (SI) units must be used, with theexception of blood pressure values which are to be reportedin mmHg. Please use the metric system for theexpression of length, area, mass, and volume.Temperatures are to be given in degrees Celsius.

Names of drugs, devices and other products:
Use the Recommended International Non-proprietary Name (rINN) for medicinal substances, unless the specific trade name of a drug is directly relevant to the discussion. Generic drug names should appear in lowercase letters in the text. If a specific proprietary drug needs to be identified, the brand name may appear only once in the manuscript in parentheses following the generic name the first time the drug is mentioned in the text.

For devices and other products, the specific brand or trade name, the manufacturer and their location (city, state, country) should be provided the first time the device or product is mentioned in the text, for example,"AKIBM SPSS Statistics 21.0 was used (IBM Corp., Armonk, NY, USA)". Thereafter, the generic term (if appropriate) should be used.

Statistical requirements:
Statistical analysis is essential for all research papersexcept case reports. Use correct nomenclature forstatistical methods (e.g., two sample t test, not unpairedt test). Descriptive statistics should follow thescales used in data description. Inferential statisticsare important for interpreting results and should be described in detail.
All p values should be expressed to 2 digits to theright of the decimal point, unless p < 0.01, in whichcase the p value should be expressed to 3 digits to theright of the decimal point. The smallest p value thatshould be expressed is p < 0.001, since additional zerosdo not convey useful information; the largest p value that should be expressed is p<0.01.

Personal communications and unpublished data:
These sources cannot be included in the references listbut may be described in the text. The author(s) mustgive the full name and highest academic degree of theperson, the date of the communication, and indicatewhether it was in oral or written (letter, fax, e-mail)form.

Items requiring explanatory footnotes should follow the same style as that for tables as described in Tables section.

Unless you have written permission from the patient (or, where applicable, the next of kin), the personal details (such as their name and date of birth) of the patient must be removed. If their face is shown, use a black bar to cover their eyes so that they cannot be identified (for further information, see

All lettering should be done professionally and should be in proportionto the drawing, graph or photograph. Photomicrographsmust include an internal scale marker, and the legendshould state the type of specimen, original magnificationand stain.

Figures must be submitted as separate picture filesat the correct resolution (see Section 9.7.2. below). Thefiles should be named according to the figure number,e.g., "Manuscript1_Fig1", "Manuscript1_Fig2".

Regardless of the application used, when your electronicartwork is finalized, please "save as" or convert the imagesto one of the following formats (note the resolutionrequirements for line drawings, halftones, and line/halftone combinations given below):
• EPS: Vector drawings. Embed the font or save thetext as "graphics".

• Do not cite uncompleted work or work that has notyet been accepted for publication (i.e., "unpublished observation", "personal communication") asreferences (also see Section 'Personal communications and unpublished data').
• Do not cite abstracts unless they are the only available reference to an important concept.

In the references list
• References should be limited to those cited in thetext and listed in numerical order, NOT alphabeticalorder.
• References should include, in order, authors' surnamesand initials, article title, abbreviated journalname, year, volume and inclusive page numbers.The last names and initials of all the authors up to6 should be included, but when authors number 7or more, list the first 3 authors only followed by"et al". Abbreviations for journal names should conform to those used in MEDLINE.

Elsevier accepts video material and animation sequences to support and enhance your scientific research. Authors who have video or animation files that they wish to submit with their article are strongly encouraged to include links to these within the body of the article. This can be done in the same way as a figure or table by referring to the video or animation content and noting in the body text where it should be placed. All submitted files should be properly labeled so that they directly relate to the video file's content. In order to ensure that your video or animation material is directly usable, please provide the files in one of our recommended file formats with a preferred maximum size of 150 MB. Video and animation files supplied will be published online in the electronic version of your article in Elsevier Web products, including ScienceDirect. Please supply 'stills' with your files: you can choose any frame from the video or animation or make a separate image. These will be used instead of standard icons and will personalize the link to your video data. For more detailed instructions please visit our video instruction pages. Note: since video and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and the print version for the portions of the article that refer to this content.

Publication Charges and Reprints

Authors of accepted articles will be charged a publication fee of US$800. In the event that a manuscript is accepted, the corresponding author will be instructed by the Editorial Office on how to transmit their payment to the Journal. The accepted article will be processed to the next stage only upon receipt of payment. Professional reprints may be ordered at

Online proof correction

Corresponding authors will receive an e-mail with a link to our online proofing system, allowing annotation and correction of proofs online. The environment is similar to MS Word: in addition to editing text, you can also comment on figures/tables and answer questions from the Copy Editor. Web-based proofing provides a faster and less error-prone process by allowing you to directly type your corrections, eliminating the potential introduction of errors.
If preferred, you can still choose to annotate and upload your edits on the PDF version. All instructions for proofing will be given in the e-mail we send to authors, including alternative methods to the online version and PDF.
We will do everything possible to get your article published quickly and accurately. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. It is important to ensure that all corrections are sent back to us in one communication. Please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.

Announcements of forthcoming regional conferencesand meetings are published free of charge. Please specifythe title of the meeting, the dates and venue, organizers and correspondence or secretariat address. Notices should be e-mailed to the Editorial Office at
