Preparing Original Articles
Full research papers that present original high-quality research should be prepared accordingly:
Title: A brief and informative title directed at the general reader. Lengthy systematic names and complicated/numerous chemical formula should, therefore, be avoided if possible.
Authors’ information: Full names (First, Middle and Last) for all authors of an article should be included and specified with the superscript number(s) for the affiliation(s) (e.g., Saeed Mohammadi1). Name of the corresponding author(s) should be specified with an asterisk before the name (e.g., Saeed Mohammadi*1).
Affiliation: Affiliation of all authors should be specified with a number before address (e.g., 1. Faculty of …..). Email addresses of all authors should be mentioned in title page as well as in the Online Submission System. ORCID IDs of the first and corresponding authors should be included in the relevant affiliations. Here is the link for ORCID registration: https://orcid.org/
Running title: A very short running title (no more than 50 characters) should be contained on the title page.
Correspondence: Corresponding author is the primary contact responsible for handling correspondence at all pre- or post-publication stages. Full address, telephone and fax numbers (with country and area code) and email of the corresponding author(s) should be stated.
Other information: The number of figures and tables used in submitted manuscript, word count and number of references should be also stated clearly.
The main document of the manuscript should include "title" not the "title page" at the top. The author is responsible for anonymity of the article. Therefore, author names should not be provided in the main document.
Abstract: A concise and factual abstract is required for all manuscripts (maximum 300 words). The abstract should describe the main objective(s) of the study, explain how the study was done, including any model organisms used, without methodological detail, summarizes the main results and their significance. This section should include Background and objectives, Methods, Results and Conclusion. References and non-standard or uncommon abbreviations should be avoided in this section.
Keywords: Immediately after the abstract, 3-6 relevant keywords should be included and separated by semicolons. Keywords should be selected according to MeSh.
"Abstract" and following "keywords" should be placed at the top of the "main document" after the "title".
The introduction should provide background and objectives of the study that allows readers outside the field to understand the purpose and significance of the study. It should define the problem addressed and why it is important in form of a brief literature review. State relevant controversies or disagreements in the subject of the study and conclude with a brief statement of the overall aim of the work. The last paragraph should address the main objectives of the work.
Materials and Methods
This section should provide enough details that allow other skilled investigators to fully reproduce the study. Specific information and/or protocols for new methods should be included in detail. If materials, methods, and protocols are well established, authors may cite articles where those protocols are described in detail, but the submission should include sufficient information to be understood independent of these references. The company’s name, city, and country of the manufacturer of the major equipment and catalog number when appropriate should be given. Unexpected hazards faced during the experimental work should be noted. Generic drug names should generally be used. When proprietary brands are used in research, include the brand names in parentheses. Studies on humans or animal models and/or tissue or field sampling must include required Ethics statements from the relevant local or national authority. The origin of the cell lines used should be stated. Submission of sequence data to databases: Novel nucleotide or protein sequence data must be deposited in the GeneBank, EMBL or DDBJ databases and an accession number obtained before the paper could be accepted for publication. For each accession number cited in an article, authors should type the accession number in capital. This section should also contain the type of statistical analysis used, including a power calculation if appropriate. They should also include a statement that informed consent was obtained for any experimentation with human subjects.
Please note that clinical trials should be registered in either a national (e.g. IRCT) or international (e.g. clinicaltrials.gov) repository.
The JCBR follows ICMJE, please consider their Guideline for more information.
This section should be written in past tense and include the findings of the study as well as results of statistical analysis, either in the text, tables and figures. Results should be brief, clear and descriptive. Attention should be paid to the matter of significant figures and tables.
The same data should not be presented in more than one figure or in both a figure and a table. Avoid duplicating the results provided in the text and tables. Discussion, speculation and data interpretation should be included in the discussion section and not in the results section.
Notice: In "Short Communications", the results and discussion sections can be combined in a single section.
