Arab Journal of Gastroenterology (AJG) publishes different studies related to the digestive system. It aims to be the foremost
scientific peer reviewed journal encompassing diverse studies related to the digestive system and its disorders, and serving the Pan-Arab
and wider community working on gastrointestinal disorders.
These guidelines generally follow the "Uniform Requirements for Manuscripts
Submitted to Biomedical Journals". The complete document appears at  http://www.icmje.org.
Submission
The
Journal accepts online submissions only. Manuscripts can be submitted at http://ees.elsevier.com/AJG/. Once the manuscript
has been uploaded, our system automatically generates an electronic pdf proof, which is then used for reviewing. All correspondence,
including notification of the Editor's decision and requests for revisions, will be managed via this system. Authors may also track the
progress of their paper using this system to final decision.
If you have any problems submitting your paper through this system,
please contact the Editorial Office at office@arabjg.eg.net.

Manuscripts
Please
type all pages with double spacing and wide margins on one side of the paper. Words to be printed in italics are to be underlined. Title
page, abstract, tables, legends to figures and reference list should each be provided on separate pages of the manuscript.
Use a
true type font such as Times New Roman or Arial. The text should be in single-column format. Number the pages. Keep the layout of the
text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the
options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. Do not embed 'graphically
designed' equations or tables, but prepare these using the facility in Word or as a separate file in Excel. When preparing tables, if
you are using a table grid, use only one grid for each individual table and not a grid for each row. Do not prepare tables in PowerPoint.
The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also http://www.elsevier.com/authors).
Do not import the figures into the text file but, instead, indicate their approximate locations directly in the electronic text and on
the manuscript. See also the section on illustrations.
To avoid unnecessary errors you are strongly advised to use the spellchecker.
The title page should include: the title, the name(s) and affiliation(s) of the author(s), an address for correspondence, and telephone/fax
numbers for editorial queries. All articles should include an Abstract (a single paragraph) of no more than 120 words and 3-6 key words
for abstracting and indexing purposes.
Ensure that the letter 'l' and digit '1' (also letter 'O' and digit '0') have been used properly,
and structure your article (tabs, indents, etc.) consistently. Characters not available on your computer (Greek letters, mathematical
symbols, etc.) should not be left open but indicated by a unique code (e.g., gralpha, @, #, etc., for the Greek letter). Such codes should
be used consistently throughout the entire text. Please make a list of such codes and provide a key. Do not allow your computer to introduce
word splits and do not use a 'justified' layout. Please adhere strictly to the general instructions on style/arrangement and, in particular,
the reference style of the journal. It is very important that you save your file in the standard format for the program you are using.
If your computer features the option to save files 'in flat ASCII', please do not use it.
Please write your text in good English
(British English is used) . Italics are not to be used for expressions of Latin origin, for example, in vivo, et al., per se. Use decimal
points (not commas); use a space for thousands (10 000 and above).
Provide the following data in your submission (in the order given).
This is required for all types of paper submitted.
Title. Concise and informative. Titles are often used in information-retrieval
systems. Avoid abbreviations and formulae where possible.
Author names and affiliations. Where the family name may be ambiguous
(e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below
the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate
address. Provide the full postal address of each affiliation, including the country name.
Corresponding author. Clearly
indicate who is willing to handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that telephone
and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.
Present/permanent
address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address'
(or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work
must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
Abstract. A
concise and factual abstract is required (maximum length 250 words). The abstract should state briefly the purpose of the research, the
principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone.
Do not cite references in the abstract. Non-standard or uncommon abbreviations should be avoided in the abstract, but if essential they
must be defined at their first mention in the abstract itself. The abstract should be divided into: Background and study aims, patients/material
and methods, results and conclusion.
Keywords. Immediately after the abstract, provide a maximum of 6 keywords, using British
spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations:
only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.
Abbreviations.
Define abbreviations that are not standard in this field at their first occurrence in the article: in the abstract but also in the main
text after it. Ensure consistency of abbreviations throughout the article.
Subdivision of the article. Divide your article
into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2), 1.2, etc. (the abstract is not included
in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text.' Any subsection may be
given a brief heading. Each heading should appear on its own separate line.
Introduction. State the objectives of the work
and provide an adequate background, avoiding a detailed literature survey or a summary of the results.
Patients/Materials and
methods. Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference:
only relevant modifications should be described.
Include in figure legends and table texts technical details of methods used, while
describing the methods themselves in the main text.
Results/Discussion. This should explore the significance of the results
of the work, not repeat them. A combined Results and Discussion section is often appropriate in a Short Communication but not in an Original
Article. Avoid extensive citations and discussion of published literature.
Acknowledgement. Collate acknowledgements in
a separate section at the end of the article and do not, therefore, include them on the title page, as a footnote to the title or otherwise.
When the work included in a paper has been supported by a grant from any source, this must be indicated. A connection of any author with
companies producing any substances or apparatus used in the work should be declared. Authors will be asked to respond to a form e-mailed
to them when their paper is accepted (see the 'conflict of interest' section below). All contributors who do not meet the criteria for
authorship as defined above should be listed in an acknowledgements section. Examples of those who might be acknowledged include a person
who provided purely technical help, writing assistance, or a department chair who provided only general support. Authors should disclose
whether they had any writing assistance and identify the entity that paid for this assistance.
References. References should
be numbered consecutively (with parentheses) as they appear in the text. Type the reference list with double spacing on a separate sheet.
References should accord with the system used in Uniform requirements for manuscripts submitted to biomedical journals (N Engl
J Med 1991;324:424-428).
Examples:
1 Taylor DN, Sanchez JL, Candler W et al. Treatment of traveller's diarrhea: ciprofloxacin
plus loperamide compared with ciprofloxacin alone. Ann Intern Med 1991;114:731-734.
2 Mackowiak PA, ed. Fever. Basic Mechanisms and
Management. New York: Raven Press, 1991.
3 Rubin M, Pizzo PA, Monotherapy in neutropenic cancer patients. In: Peterson PK, Verhoef
J, eds. Antimicrobial Agents Annual 3. Amsterdam: Elsevier, 1988.
Please note that all authors should be listed when six or less;
when seven or more, list only the first six and add 'et al.'. Do not include references to personal communications, unpublished data
or manuscripts either 'in preparation' or 'submitted for publication'. If essential, such material may be incorporated into the appropriate
place in the text. Recheck references in the text against reference list after your manuscript has been revised.
Illustrations.
Photographs should be presented as high quality jpg (jpeg) or tiff files with high contrast. Magnification should be indicated by a line
representing the actual scale of reproduction (0.1 mm, 1mm or 10 mm); the use of magnification factors is to be avoided where possible.
Illustrations will not be redrawn by the Publisher: line figures should be suitable for direct reproduction. They should be prepared
with black on white background, or be black-and-white images; they should be completely and consistently lettered, the size of the
lettering being appropriate to that of the illustration, taking into account the necessary reduction in size.
Illustrations
should be designed to fit either a single column (84 mm wide) or the full text width (175mm). However, if specifically requested by the
author(s), plates may be reproduced larger than the typeset area; all originals for these should have the same proportions to achieve
uniformity in their presentation. N.B. When plates are required to fill the entire page, the originals should have the dimensions
215 x 285 mm and contain no essential information or labelling near the edges. Further information about artwork can be found on
the World Wide Web: access under http://www.elsevier.com/locate/authorartwork
Colour figures. Colour figures
will be included subject to the authors' agreement to defray the cost.
Mathematical formulae. Present simple formulae in
the line of normal text where possible. In principle, variables are to be presented in italics. Use the solidus (/) instead of a horizontal
line, e.g., Xp/Ym.
Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed
separate from the text (if referred to explicitly in the text).
Tables. Number tables consecutively in accordance with their
appearance in the text. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Avoid vertical
rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the
article.
Nomenclature and units. Follow internationally accepted rules and conventions: use the international system of
units (SI). If other quantities are mentioned, give their equivalent in SI.
DNA sequences and GenBank Accession Numbers.
Many Elsevier journals cite 'gene accession numbers' in their running text and footnotes. Gene accession numbers refer to genes or DNA
sequences about which further information can be found in the databases at the National Center for Biotechnical Information (NCBI) at
the National Library of Medicine. Elsevier authors wishing to enable other scientists to use the accession numbers cited in their papers
via links to these sources, should type this information in the following manner:
For each and every accession number cited in an
article, authors should type the accession number in
bold, underlined text
. Letters in the accession number should always
be capitalised. (See example below.) This combination of letters and format will enable Elsevier's typesetters to recognise the relevant
texts as accession numbers and add the required link to GenBank's sequences.
Example: GenBank accession nos.
AI631510
,
AI631511
,
AI632198
, and
BF223228
, a B-cell tumour from a chronic lymphatic leukaemia (GenBank
accession no.
BE675048
), and a T-cell lymphoma (GenBank accession no.
AA361117
).
Authors are encouraged
to check accession numbers used very carefully. An error in a letter or number can result in a dead link. In the final version
of the
printed article
, the accession number text will not appear bold or underlined. In the final version of the
electronic
copy
, the accession number text will be linked to the appropriate source in the NCBI databases enabling readers to go directly
to that source from the article.
Editorial Review
All manuscripts are subject to peer review. If changes are requested,
revisions received later than 3 months after this request will be treated as new submissions.
Proofs
One set of page proofs
in PDF format will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent
by post). Elsevier now sends PDF proofs which can be annotated; for this you will need to download Adobe Reader version 7 available free
from http://www.adobe.com/products/acrobat/readstep2.html. Instructions on how to annotate PDF files will accompany the
proofs. The exact system requirements are given at the Adobe
site. If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query
Form) and return to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible,
then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax,
or scan the pages and e-mail, or by post.
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. We will do everything possible to get your article published quickly and accurately. Therefore, it is
important to ensure that all of your 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. Note that Elsevier may proceed
with the publication of your article if no response is received.
Page charges
The Journal does not charge a submission
fee.
Offprints
The corresponding author, at no cost, will be provided with a PDF file of the article via e-mail. The PDF
file is a watermarked version of the published article and includes a cover sheet with the journal cover image and a disclaimer outlining
the terms and conditions of use. Paper offprints can be ordered by the authors. An order form with prices will be sent to the corresponding
author.
Policy and Ethics
Declarations
Upon submission you will be required to complete and upload this form
(pdf version or word version) to declare funding, conflict of interest and to indicate whether ethical approval was sought. This information
must also be inserted into your manuscript under the acknowledgements section with the headings below. If you have no declaration to
make please insert the following statements into your manuscript:
Funding: None
Competing interests: None declared
Ethical
approval: Not required
Ethics
Work on human beings that is submitted to AJG should comply with the principles laid down
in the Declaration of Helsinki; Recommendations guiding physicians in biomedical research involving human subjects. Adopted by the 18th
World Medical Assembly, Helsinki, Finland, June 1964, amended by the 29th World Medical Assembly, Tokyo, Japan, October 1975, the 35th
World Medical Assembly, Venice, Italy, October 1983, and the 41st World Medical Assembly, Hong Kong, September 1989. The manuscript should
contain a statement that the work has been approved by the appropriate ethical committees related to the institution(s) in which it was
performed and that subjects gave informed consent to the work (see declarations section above). Studies involving experiments with animals
must state that their care was in accordance with institution guidelines.
Studies on patients or volunteers require ethics committee
approval and informed consent which should be documented in your paper. Patients have a right to privacy. Therefore identifying information,
including patients, images, names, initials, or hospital numbers, should not be included in videos, recordings, written descriptions,
photographs, and pedigrees unless the information is essential for scientific purposes and you have obtained written informed consent
for publication in print and electronic form from the patient (or parent, guardian or next of kin where applicable). If such consent
is made subject to any conditions, Elsevier must be made aware of all such conditions. Written consents must be provided to Elsevier
on request. Even where consent has been given, identifying details should be omitted if they are not essential. If identifying characteristics
are altered to protect anonymity, such as in genetic pedigrees, authors should provide assurance that alterations do not distort scientific
meaning and editors should so note. If such consent has not been obtained, personal details of patients included in any part of the paper
and in any supplementary materials (including all illustrations and videos) must be removed before submission.
Competing interests
See the declarations section above. All authors must disclose any financial and personal relationships with other people or organisations
that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies,
stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding.
Role of the
funding source
See the declarations section. All sources of funding should be declared. Authors should declare the role of study
sponsors, if any, in the study design, in the collection, analysis and interpretation of data; in the writing of the manuscript; and
in the decision to submit the manuscript for publication. If the study sponsors had no such involvement, the authors should so state. |
