(4)    Introduction

(5)    Methods

(6)    Results

(7)    Discussion

(8)    Acknowledgements

(9)    References


(11)Text tables

(12)Figure legends


Please refer to the ICMJE recommendations on manuscript preparation and submission. The format may be altered for review articles, if necessary.


The title page bears:

(a) Title

(b) Name(s) of Author(s)

(c) Institution(s) where work was done

(d) "Reprint request to" information consisted of name of author to whom the reprint version should be sent with complete address, telephone number, and e-mail address.



An abstract (maximum 250 words) is typed single space. The abstract is structured under the headings:

(1) Background

(2) Objective

(3) Methods

(4) Results

(5) Conclusion



No more than six keywords are required, separated by a semicolon.


Units and Abbreviations 

Measurement unit should be stated using standard SI units.



Substantive contributions of individuals should be noted in an Acknowledgements section and entered before the Conflict of Interest (COI) statement.



Details of all funding sources for the work in question should be given in a separate section entitled 'Funding'. This should appear before the 'Acknowledgements' section.

The following rules should be followed:

a) The sentence should begin: ‘This work was supported by …’

b) The full official funding agency name should be given, i.e. ‘the National Cancer Institute at the National Institutes of Health’ or simply 'National Institutes of Health' not ‘NCI' (one of the 27 sub-institutions) or 'NCI at NIH’ (full RIN-approved list of UK funding agencies)

c) Grant numbers should be complete and accurate and provided in brackets as follows: ‘[grant number ABX CDXXXXXX]’

d) Multiple grant numbers should be separated by a comma as follows: ‘[grant numbers ABX CDXXXXXX, EFX GHXXXXXX]’

e) Agencies should be separated by a semi-colon (plus ‘and’ before the last funding agency)

f) Where individuals must be specified for certain sources of funding, the following text should be added after the relevant agency or grant number 'to [author initials]’.


An example is given here: ‘This work was supported by the Indonesia Academy of Science [grant numbers]’



Figures should be limited to the number necessary for clarity and must not duplicate data given in tables or in the text. Standard submissions should have no more than 8 total figures and tables. Any number exceeding this should be designated as supplementary online-only material. They must be suitable for high-quality reproduction and should be submitted in the desired final printed size so that reduction can be avoided. Figures should be no larger than 125 (height) x 180 (width) mm (5 x 7 inches) and should be submitted under the respective header (“Figure”) and in files separates from that of the main manuscript.


Electronic submission of figures: Figures should be saved in TIFF format at a resolution of at least 300 pixels per inch at the final printed size for color figures and photographs, and 1200 pixels per inch for black and white line drawings. While some formats can be converted into TIFFs by the publisher, conversion may alter the tones, resolution and contrast of the image. Digital colour art should be submitted in CMYK rather than RGB format, since the printing process requires colors to be separated into CMYK, and this conversion can alter the color intensity and brightness. Please keep in mind that colors can appear differently on different screens and printers.


Line drawings should be clear: faint shading or stippling will be lost upon reproduction and should be avoided and heavy shading or stippling may appear black. Lines and symbols should be drawn boldly enough to stand reduction to the desired size. For graphs where reduction to one-half in linear dimensions is intended, a suitable thickness for the axis would be 0.3 mm and for the other lines 0.4 or 1.0 mm depending on the complexity of the graph. The preferred symbols are closed circle, open circle, closed square, open square, closed triangle, and open triangle and should be no smaller than 2 mm (height/diameter).


Photographs: Photographs should be of sufficiently high quality, i.e. JPG or TIFF formats with a minimum file size of 1 MB, and 300 dpi.  Please ensure that the photographs are of high quality with respect to detail, contrast, and low noise, to enable them to withstand loss of contrast and detail inherent in the printing process.


Colour figures: There are no charges for colour figures. Colour plates should be combined to make a single composite figure whenever possible.


Legends: A separate typewritten, double-spaced list of legends of all figures must be supplied and included in the text file. Each legend should contain sufficient explanation to be meaningful without cross-referencing. A scale of the original should be included in the legend unless already indicated in the picture. A description of the symbols used in the figures should be written out in full. Please do not include the character symbol in the legend. All labels used in figures should be in lower case in both the figure and the legend.



Tables should be typed with single spacing, but minimizing redundant space, and each table should be placed in separate pages. Wherever possible, tables should be submitted in portrait - as opposed to landscape - layout. Each table should be numbered in sequence using Arabic numerals. Tables should also have a title above and an explanatory footnote below.



The references used in this journal follow the “Uniform requirements for manuscripts submitted to biomedical journals” (updated February 2006) published by International Committee of Medical Journal Editors with some modifications. References cited should be numbered consecutively in superscript by Arabic numerals in the order they first appear in the text. Identify also references in the tables and legends by Arabic numerals in superscript.

Please make sure that every numbered reference in the text appears in the reference list, and vice versa. Reference cited only in tables or in legends should be numbered in accordance established by their first identification in the text. List authors, years, volume, and inclusive pages (the beginning and the last pages) of all journal references, and specific page numbers for all book references as shown below. Avoid referencing abstract, but if they are used, indicate them as such by the abbreviation [abstr] after the title. Do not use periods or semicolons after authors initials or after abbreviations. Personal communications, unpublished observations, and manuscripts submitted but not yet accepted for publication do not constitute references. Limit the use of electronic sources that have not been published in journals. Please rigidly follow the following examples of the most frequently used references. 

Personal communications, manuscripts in preparation and other unpublished data are not cited in the reference list but are mentioned in the text in parentheses.

Titles of journals should be abbreviated in accordance with Medline. Complete information should be given for each reference, including title of article, abbreviated journal title and inclusive pagination. All authors should be listed.

Authors are encouraged to use referencing software for the manuscript.
