These guidelines are based on ICMJE recommendations.

Permission and copyright: Where relevant, it is the responsibility of the authors to obtain permission from copyright holders, and to ensure that the use of images, data and illustrations in the manuscripts do not violate copyright laws. If a copyright violation in any of the published article is brought to our attention, we will notify the author for correspondence. It is the responsibility of the author(s) to settle issues with the copyright holder.

General: Manuscripts should be written in English using size 12 Roman font. The overall margin should be 2.54 cm (1 inch) with double space between lines. The manuscript should be submitted as a single file Microsoft Word document, with tables and figures inserted after the references. Also high resolution TIFF images should be uploaded separately. The page numbers should be included at the bottom right of the document. The overall guidelines are same for all article types; however, there are some minor variations for review articles, case reports and letter to editor. These are given at the end of this page. The following are the guidelines for original articles. Arrange the articles in the described order. 

Title page: Title of the article, author(s), affiliation of the author(s), email of all authors and contact details of the author for correspondence.   

Abstract: No more than 250 words, unstructured single-paragraph without any references. The abstract should be written in such a way that it conveys the entire message of the article.

Short title: Below the abstract include a short title (maximum 50 characters including space)

Keywords: Below the short title, include five keywords in alphabetical order, each separated by semi-colon. 

Introduction: Describe why you are doing what you are doing in the light of the available literature. 

Materials and Methods: Describe each method under separate headings. If relevant, include a statement about ethics approval and ethics approval number. Policy concerning ethics approval is included here. Describe the methods clearly. Mention the number of samples, equipment and chemicals used, and the number of repeats. Include the statistical methods used. Include the catalogue number of antibodies. 

Results: Describe the results obtained and the level of significance. Do not repeat tabulated results in the text. Reference to tables and figures should be made parenthetically in the text, for example (Figure 1 or Table 1). 

Discussion: Describe your findings but ensure that this is not a repeat of the ‘Results’ section. What is novel about your results? How do your results compare or contrast with the existing literature? What is your message to the scientific community? 

Conclusion: Write a concluding paragraph summarising your findings and suggestions for future directions.

Acknowledgements: Acknowledge your colleagues and sources of finance that made this research possible. 

Conflict of interest:  Declare any conflicts of interest that are pertinent to the current manuscript. More information on conflict on interest is given here. If you do not have any conflict of interest then write "The authors declare no potential conflicts of interest with respect to research, authorship and/or publication of this article"

References: The authors are not required to include doi in the reference list. The publisher will take care of it during the production stage.  Use Vancouver style. References should be cited in numerical order (in parentheses) in the text and listed in the same numerical order at the end of the manuscript. If you use any software to generate references, manually verify that they are accurate and adhere to the requirements. Examples are given below (adapted from Monash University). The best way to ensure accuracy is to download from PubMed.

Tables:  All tables should be created with the 'insert table' function of Microsoft Word. Tables should fit within the page margin (2.54 cm or 1 inch). The tables should be cited in numerical order in the text (Table 1, Table 2 etc). Each table should have a table number and a descriptive title above the table. Explanations for abbreviations and levels of significance should be given at the bottom of the table as letters in superscript (for example a, b, c etc), not as symbols (for example @, # etc.). Insert table(s) immediately after the references.

Figures and figure legends: All illustrations are referred to as "Figures" and must be numbered consecutively, for example (Figure 1, Figure 2 etc). Photomicrographs should be high resolution TIFF images (minimum 300 dpi). After creating the images as high-resolution TIFF images, use the 'insert picture' function of the Microsoft Word to insert figures at the end of the article immediately after the tables. Provide figure legends including figure number, a short title and description immediately below each image. Also upload the figures separately during submission process. Photomicrographs should have internal scale markers. Symbols, arrows, or letters used in photomicrographs should contrast with the background. Explain the internal scale and identify the method of staining in photomicrographs.

Units: Measurements of length, height, weight, and volume should be reported in metric units (meter, kilogram, or liter) or their decimal multiples. Temperatures should be in degrees Celsius. Blood pressure should be in millimeters of mercury.

Abbreviations and Symbols: Use only standard abbreviations. Avoid abbreviations in the title of the manuscript. The spelled-out abbreviation followed by the abbreviation in parenthesis should be used on first mention unless the abbreviation is a standard unit of measurement.

Review articles: The style, title page, abstracts, tables, references and quality of images are similar to the above guidelines. The article should be organized in the following order: Title page, Abstract, Introduction, Contents under various subheadings, Conclusion, Acknowledgements (if relevant), Conflict of interest, References, Tables, Figures, and Figure legends below respective figures. A review article can be between 3000 and 5000 words, excluding the abstract and references. Do not number the headings. 

Case reports: The style, title page, abstracts, tables, references and quality of images are similar to the above guidelines. Write the case report under four major headings – introduction, case report, discussion and conclusion.

Letter to editor: Comments about any of the articles that had been published in JRENHEP can be submitted as letter to editor. The word limit is 500 including references. These will undergo independent peer review and sent to the author for correspondence of the article in question. After exchange between the authors through the editorial support staff, the letter along with the response of the authors will be published.
