Guide for Authors


Journal of Advanced Research (JAR) provides publication of various original articles in the fields of basic sciences, applied sciences and technology, biomedical sciences, and related disciplines. 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.

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 would have observed 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.

Every peer-reviewed research article appearing in this journal will be published open access. This means that the article is universally and freely accessible via the internet in perpetuity, in an easily readable format immediately after publication. The author does not have any publication charges for open access. Cairo University will pay to make the article open access.

A CC user license manages the reuse of the article (see All articles will be published under the following license: CC BY-NC-ND license Creative Commons Attribution-NonCommercial-NoDerivs (CC BY-NC-ND)

For non-commercial purposes, lets others distribute and copy the article, and to include in a collective work (such as an anthology), as long as they credit the author(s) and provided they do not alter or modify the article.

Review process
Manuscripts are evaluated on the basis that they present new insights to the investigated topic and are likely to contribute to a research progress or 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 be first examined by the JAR editorial office and manuscripts with insufficient priority for publication will be rejected without external evaluation. Manuscripts not prepared in the advised style 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 registered manuscripts will be sent to independent experts for scientific evaluation. We encourage authors to suggest the names of four potential reviewers; however, the editors reserve the right of final selection. The evaluation process usually takes on average 1-3 months. Submitted papers will be accepted for publication after a positive opinion of the reviewers and editors. Authors should return the revised manuscript within 30 days from receiving an editorial decision.

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 this 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.

Conflict of interests
A conflict of interest may exist when an author or the author's institution has a financial or other relationship with other 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 all relationships that could be viewed as presenting a potential conflict 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. A decision may be made by the journal not to publish on the basis of the declared conflict. This declaration (with the heading "Conflict of interests") should be fulfilled on the cover page at the time of submission.

Materials taken from other sources must be accompanied by a written statement from both author and publisher giving permission to the journal for reproduction.

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 contents or prepare lists of articles including abstracts for internal circulation within their institutions. Permission of Cairo University is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations.

Every effort is made by the publisher and editorial board to see that no inaccurate or misleading data, opinion or statement appears 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 such inaccurate or misleading data, opinion, or statement, whether intentional or not.


  • Original articles: Articles which represent in-depth research in various scientific disciplines.
  • 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.
  • 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. A special attention will be paid to a teaching value of a review paper.
  • Mini reviews: These are reviews of important and recent topics that are presented in a concise and well-focused structure. The number of words is limited to 5,000 words.
  • 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 ≤ 2,500.
  • Letter to the editor for comments on recently published articles.
  • 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.

3. Preparation of manuscripts and reports

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 the letter type Arial and/or Times New Roman (12 pt). The text should be in single-column format with justified margins. Do use bold face, italics, subscripts, and superscripts. To avoid unnecessary errors, the authors are strongly advised to use the "spell-check" and "grammar-check" functions of their word processing. All manuscript pages must be numbered at the bottom right corner of each page.

General requirements
All submitted papers are subject to double blind peer-review and authors are urged to be brief; long papers with many tables and figures may require shortening if they are to be accepted for publication. While there is no length restriction for papers, authors are encouraged to limit the text to a maximum length of 4,000 words and references preferably not to be more than 35.
The manuscript should be compiled in the following order:

  • Abstract, Key words
  • Introduction
  • Material and methods (Experimental or Methodology or Patients and methods)
  • Results
  • Discussion (Results and discussion can be combined in one section)
  • Conclusion
  • Acknowledgment(s)
  • References
  • Tables
  • Figures
Manuscripts must be written in clear, concise, English language. Any author who is not fluent in idiomatic English is urged to gain assistance with manuscript preparation. Reviewers are not expected to correct grammatical errors and any deficiency in this area may detract from the scientific content of the paper.

The following items should be uploaded via Elsevier Electronic Submission (EES),
