Editorial policy and general information

The Journal of Advanced Research (JAR) publishes original articles in the fields of the basic sciences, applied sciences and technology, biomedical sciences, and related disciplines. JAR seeks to publish high-quality papers that: 1) describe significant and novel findings; and 2) advance knowledge in a diversity of scientific fields in the form of original articles, short communications, reviews, case reports, or letters to the editor.

Review process
Manuscripts are evaluated on the basis that they present new insight into the investigated topic and are likely to contribute to research progress or a change in clinical practice. It is understood that all authors listed on a manuscript have agreed to its submission. The signature of the corresponding author on the letter of submission signifies that these conditions have been fulfilled. Received manuscripts will initially be examined by the JAR editorial office and those deemed to have insufficient grounds for publication may be rejected without external evaluation. Manuscripts not prepared in the advised style described below will be sent back to authors for correction. The authors will be notified with the reference number once the manuscript has been assigned to an Editor. The assigned manuscripts will be sent to 2-4 independent experts for scientific evaluation. The evaluation process commonly takes an average of 1-3 months.

Authors wishing to include figures, tables, or text that have already been published elsewhere are required to obtain permission from the copyright owner(s) for both the print and online format and to include evidence that such permission has been granted when submitting their papers. Any received material lacking such evidence will be assumed to originate from the authors.

Every effort is made by the publisher and editorial board to ensure that no inaccurate or misleading data or statements appear in the Journal of Advanced Research. However, they wish to make it clear that the data and opinions appearing in the articles herein are the responsibility of the authors concerned. Accordingly, the publisher and the editorial board accept no liability whatsoever for the consequences of any inaccurate or misleading data or statements, intentional or not.

Articles types

JAR seeks to publish experimental and theoretical research results of outstanding significance in the form of original articles, short communications, reviews, case reports, or letters to the editor.

  1. Original articles: Articles which represent in-depth research in various scientific disciplines.
  2. Short communications: Should be complete manuscripts of significant importance. However, their length and/or depth do not justify a full-length paper. The total number of figures and tables should not exceed 4. The number of words should be = 3,000
  3. Review articles: Should normally comprise less than 10,000 words; contain unstructured abstract and includes up-to-date references. Meta-analyses are considered as reviews. Special attention will be paid to the teaching value of review papers.
  4. Mini reviews: These are reviews of important and recent topics that are presented in a concise and well-focused manner. The number of words is limited to 5,000 words.
  5. Case reports: A detailed report of the symptoms, signs, diagnosis, treatment, and follow-up of an individual patient (i.e., clinically important information on common and rare conditions).
  6. Letter to the editor for comments on recently published articles.
  7. Special reports: Papers may be accepted on the basis that they provide a systematic, critical and up-to-date overview of literature pertaining to research or clinical topics.

Ethics in publishing

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

Ethical approval

Studies on patients or volunteers require Ethics Committee and/or Independent Review Board (IRB) approval, and, where relevant, the patients' written informed consent, which should be documented in the Methods section of the paper. If such a study was not approved by the appropriate Ethics Committee or IRB, a statement as to why it was exempted should be included. The Editors reserve the right to refuse publications where the required ethical approval/patient consent is lacking.

Human and animal rights

The JAR editors endorse the principles embodied in the revised Declaration of Helsinki (2008) (59th WMA General Assembly, Seoul, Republic of Korea, October 2008) and expect that all investigations involving humans would have been performed in accordance with these principles. For animal experimentation, it is expected that investigators have abided by the Interdisciplinary Principles and Guidelines for the Use of Animals in Research, Testing, and Education issued by the New York Academy of Sciences Adhoc Committee on Animal Research. All human and animal studies must have been approved by the investigator's Institutional review board.

Conflict of Interest (mandatory)

A conflict of interest may exist when an author or the author's institution has financial or other affiliations with people or organizations that may inappropriately influence the author's work. A conflict can be actual or potential and full disclosure to the journal is the safest course. All submissions to the journal must include disclosure of any relationships that could be viewed as potential conflicts of interest. The journal may use such information as a basis for editorial decisions and may publish such disclosures if they are believed to be important to readers in judging the manuscript. This declaration (with the heading "Conflict of interests") should be uploaded among the files submitted on the EES. Additional information regarding conflicts of interest can be found at

Submission declaration and verification

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 in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder. To verify originality, your article may be checked by the originality detection service CrossCheck.

Changes to authorship

Request to changes in authorship is not allowed once the paper is accepted. In case any such changes needs to be made then the author would have to withdraw his paper and resubmit it with the new author details in the Editorial System.


Upon acceptance of an article, authors will be asked to complete a 'Copyright Transfer Agreement'. Acceptance of the agreement will ensure the widest possible dissemination of information. Subscribers may reproduce tables of content or prepare lists of articles including abstracts for internal circulation within their institutions. Permission from Cairo University is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations.

General information

Authors should submit their manuscripts to the editorial office as word files via the Elsevier Editorial System (EES) at The original manuscript should be formatted with double line spacing using Arial or Times New Roman fonts (12 pt). The text must be in a single-column format with justified margins. Use bold face, italics, subscripts, and superscripts where appropriate. To avoid unnecessary errors, the authors are strongly advised to use the "spell-check" and "grammar-check" functions of their word processing software. Use continuous line numbering throughout the text and all manuscript pages must be numbered at the bottom right corner of each page.

Revised manuscripts
The authors must submit the revised version of their submissions within one month of receiving the editorial decision. Revision does not mean that the manuscript will be accepted for publication, as the amended submissions could be sent out for reevaluation. In response to reviewers’ comments, the authors must ensure that each comment is followed by their revision and/or response. In instances where an author disagrees with a comment or suggestion of a reviewer, please justify the reason. Any associated changes in the manuscript must be highlighted on the revised form of the manuscript to facilitate the process of reevaluation.

Resubmission of a rejected manuscript
When resubmitting a manuscript previously rejected by JAR, the authors are required to upload the decision letter from the Editor requesting submission of the rejected manuscript, the original reviewer comments of the rejected manuscript, the responses to the reviewer comments, and the original manuscript number. The resubmitted manuscript must indicate, in color, where the revisions were made in the paper in response to the reviewer comments

Single blind review
This journal uses single-blind review, which means that the reviewer name(s) will not be revealed to the author(s) of a manuscript under review. For more information, please refer to

Peer review

This journal operates a single 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.

Article structure
