Author Guidelines

Cover letter and submission responsibility

The submitting author takes responsibility for the article during submission and peer review.

The cover letter is mandatory and should include:
1. Explanation on the importance of the manuscript (why your manuscript should be published?)
2. Declaration of any competing interests
3. The names, institutions and e-mail addresses of three potential peer reviewers for the manuscript. These should be experts with the proven track record and a number of publications in the field, who will be able to provide an objective assessment of the manuscript. Any suggested peer reviewers should not have published with any of the authors of the manuscript within the past three years, should not be current collaborators, and should not be members of the same research institution. Suggested reviewers will be considered alongside potential reviewers recommended by the Editorial Board.

Manuscript content requirements

JHSci supports the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network international initiative that seeks to improve the reliability and value of published health research literature by promoting transparent and accurate reporting and wider use of robust reporting guidelines.

Before submitting, check the content of your manuscript against the appropriate guideline at http://www.equator-network.org/

We highly recommend the authors to use the appropriate guideline from EQUATOR NETWORK when writing their manuscripts.  Also, we recommend the authors to review previously published articles in the Archives to familiarize with the structuring requirements of the JHSci.

Formatting requirements


The text of the research article must be formatted in standard scientific format (Abstract, Introduction, Methods, Results, Discussion, (Conclusion). Review articles may have a different structure.

Introduction is a concise part of the manuscript. It must contain a description of the problem that this paper deals with, by showing the problem from the broader context and current situation, moving to a specific problem which this paper tries to resolve. At the end of the introduction, it is necessary to clearly point out the purpose, goals and/or hypothesis this study.

Methods. This section should be brief. The templates that JHSci has provided on the website have more information about the content of this chapter.

Results. Give priority to a graphical representation of the results of studies, whenever applicable. Use subheadings in order to achieve greater clarity of work. More information can be found in the templates.

Discussion. This section should give meaning to the results obtained, indicate the new discoveries which have been identified, indicate the results of other studies that have dealt with a similar problem. Compare your results with other studies and highlight the differences and novelties in own results. In this chapter, the results should be comprehensively interpreted, analyzed and new knowledge synthesized from the analysis. A short conclusion should close the discussion section or conclusion may be given in a separate section.

Conclusion should be brief and contain the most important facts which have been identified in the paper. Conclusions must arise from the results obtained during the investigation and should include the possible application of these results. Both affirmative and negating conclusions should be stated.

Competing interests have to be stated in this section or authors declare no conflict of interest.

(Acknowledgements) if any, should be stated in this section.


Tables have to be placed at the end of the main manuscript text file. Tables should NOT be formatted other than simple borders and no colors. Table number and the title is written above the table. A table gets number in the order of appearance in the text, with a clear and sufficiently informative title, i.e. "Table 3. Text table name...." A reference to the table in the text is written in parentheses, i.e. (Table 3). All the abbreviations in the table must be explained in full below the table. It is desirable to give explanations and comments below the table, which are essential for the presented results to be understood. Display the statistical measures of variations such as standard deviation and standard error of the mean, when applicable.


Figures and figure legends are to be placed after the Tables at the end of the main manuscript file. In addition, high-resolution figures are submitted separately during the submission process. Figure legends (explanations) should be informative and detailed. Figures get the numbers by the order of appearance in the text. Figure number and legends are written below the figure, for example, "Figure 3. Title text...". When referring to a figure in the manuscript text, the number of the figure has to be written in parentheses, e.g., (Figure 3). It is essential that the figure has a clear and informative title and legend which explains the presented results with sufficient details. Figure resolution must be at least 300 dpi, JPG or TIFF. Font size within figures must be legible when the figure is resized to its final size (i.e. the width of one column (8cm), or two columns (16 cm)). We recommend using a larger font size than the manuscript text.


References should be numbered in order of appearance in the paper. In the text, references should be put in brackets, i.e. (12). When the reference has up to 6 authors, list all authors. If 7 or more authors, list only first 6 and add et al. References should include name and source of information (Vancouver style). Names of journals should be abbreviated as in PubMed. http://www.ncbi.nlm.nih.gov/journals
