Graphical Abstract:

Graphical abstract is optional in JHPR. Authors are encouraged to provide a graphical abstract. A graphical abstract is a figure that clearly and succinctly conveys the main message of your research (paper). The graphical abstract will be displayed in online search result lists, and the online article, but will not appear in the article PDF file. Graphical abstracts should be submitted as a separate file during online submission.


Image size: Please provide an image with ratio (200 high x 500 wide) pixel, rectangle, minimum 300 dpi resolution, and maximum size 300 x 750 pixel.

File type: Preferred file types are TIFF or PNG.

Font: Please use Times or Arial font with a large enough font size (Maximum 30 words).

Introduction: The introduction should provide the necessary background information for the average reader; it should be both complete and concise. Previous and recent publications that form a basis for the work presented should be cited.

Materials and Methods: In the Materials and Methods section, the experimental procedures should be cited and described in sufficient detail. This section should be made as concise as possible by reference to procedures that have already been published. Treatments, experimental design, and statistical method must be explained in detail.

Results and Discussion: Results should be presented with clarity and precision. The discussion should interpret the meaning of findings in view of the results obtained and compare them with other previous studies. The discussion section should not contain a repeat of the results. It is also possible to present results and discussion in separate sections.

Conclusion: State the conclusions in a few sentences at the end of the paper in a separate section.

Acknowledgment(s): The Acknowledgements section should be brief. Any grant that requires acknowledgment(s) should be mentioned. The names of funding organizations should be written in full.

Conflict of Interest: If there is no conflict of interest to declare, do still include this section and insert "The authors have no conflict of interest to report".

Literature Cited: Authors are encouraged to cite only published or in press, significant and up-to-date references in their papers. Please do not cite abstracts.

Text: If references are made in the text listed in Literature Cited, refer to them by the author's family name(s) and the year published according to the APA referencing system, briefly identified in Appendix 1. Groups of references should be listed first chronologically, then alphabetically. Citation of a reference as 'in press' implies that the item has been accepted for publication.

List: All literature cited should be listed in an alphabetical order, by the author’s family names. More than one reference from the same author(s) in the same year must be identified by the letters 'a', 'b', 'c', etc., placed after the year of publication. If copying references, please be careful as they may already contain errors or did not in a perfect format even when using Google Scholar. A DOI should be provided for all references where available. Note that authors are fully responsible for the accuracy of the references.

Please use Crossref free of charge and find DOI of articles quickly and then add them in the reference list of your manuscript. (New)

Equations: The mathematics equations must be left-aligned on the page, with numbers (e.g., (1)) on the right (see published papers in the JHPR). Use the equation editor or MathType for equations.

Tables and Figures: Please submit tables and figures (graphs) as editable text and not as images. Manuscripts should contain all figures of high quality suitable for publication. Please avoid using vertical lines in tables. All figures and tables should be embedded while correctly positioned. Please use "Table" in both text and captions. However, use (Fig.) at the end of the sentence and captions and use Figure in text. JHPR will not publish landscape pages, so provide all tables and figures suitable for portrait orientation with a maximum width 16 cm. Totally include up to 8 tables and figures in the manuscript. Footnotes to tables should appear beneath the tables and should be designated by a lower-case superscript letter, †, or z, y, x, etc. (Appendix 2).

Total no. of Tables + figures: 8

Numbers, Dates, and Units: A common style uses words for numbers from 1 to 9 and numerals for numbers of 10 and above, for example, 'more than two' and 'over 500', (except at the start of a sentence). It is almost always best to write dates using a word (in full or abbreviated) for the month: 12 November 2016 or 12 Nov 2016. The abbreviated forms are commonly used in tables. Place the unit after the numeral, with space in between; 2 ml, 10 kg, 6 min, 22 °C. The JHPR follow the SI for units of measurement (SI units is available in JHPR website). SI recommends using the negative exponential with units: 2 mg kg-1, rather than 2 mg/kg. Levels of statistical significance which can be mentioned without further explanation are: *, P ≤0.05 and **, P ≤0.01. For converting different units to SI you can also visit website.
