Introduction -This section states the purpose of the research and includes a brief summary of the literature describing the current state of the field.
Materials and Methods - This section states exactly what was done and should enable a reader to replicate the work. The location of a manufacturer (manufacture name, city, state, country) listed in the text should be included. Statistical methods used should be outlined. Ethical guidelines for human or animal study should be described and approval of institutional human research review committee or animal welfare committee should be cited. Describe in detail hazardous procedures or chemicals involved, including precautions observed.
Results - This section should describe the objective findings without any comment on their significance or relative importance. Cite all tables and figures in sequential order in the text.
Discussion - Discussion considers the results in relation to any hypotheses advanced in the introduction. This may include an evaluation of the methodology and of the relationship of new information to the existing corpus of knowledge in that field. Data given in the results section should not be reiterated here. Only this section allows you freedom to interpret your data and to give your opinion of the value of your findings relative to previous work
Conclusion - This section states what conclusions can be drawn specifically from the research reported.
References - References cited must refer to published material. Number references consecutively in order of their appearance in the manuscript using superscript and Arabic numerals. References to "personal communication" or unpublished these are not acceptable. The style and punctuation of references should strictly conform to American Medical Association Manual of Style: A Guide for Authors and Editors, 9th ed (Baltimore, Md: Williams & Wilkins; 1998).
The source of financial grants and other funding should be acknowledged, including a frank declaration of the authors' industrial links and affiliations. The contribution of colleagues or institutions should also be acknowledged. Thanks to anonymous reviewers are not allowed.
Each table must be simple and typed on a separate page with its heading above it. Explanatory matter is placed in footnotes below the tabular matter and not included in the heading. All non-standard abbreviations are explained in the footnotes.
Footnotes should be indicated by superscripts a, b and c etc. The word "number" should be abbreviated as "n" to express the number of samples or subjects. For example, it should be written as (n=24). Statistical measures such as SD or SE (M) should be identified. Vertical rules and horizontal rules between entries should be omitted. Each table is referred in the text consecutively and numbered according to order of citation. The tables and its legend/footnotes should be understandable without reference to the text. The order of footnotes is as follows; after it is indicated by superscript a, b and c etc, then the abbreviation is explained.
Figure legends should be typed double-spaced on a separate sheet following Figure 1 or Figure 2. Symbols, arrows and letters indicating parts of illustrations should be explained in the legend. Each figure should be referred in the text consecutively as Fig. 1 or Fig. 2 in parenthesis and should be numbered according to order of citation. If figure is indicated in the sentence without the parenthesis, then it should be described as Figure 1.
Each figure must be of sufficient resolution for high quality publication usually in TIFF or EPS format. All images need to be at 300 DPI when the figure is of the size to be used in publication.
If you enter a large image at 300 DPI and reduce it to a much smaller size for publication, this will increase the DPI and the image will be very heavy and slow to open electronically. If you enter a small image (such as a 35 mm picture) and plan to enlarge it for publication, it needs to be entered at more than 300 DPI since enlargement will only reduce the resolution.
If a figure consisted of at least 2 sections, each figure should be listed as A, B or C in the upper left corner of each figure. The statistical difference (P-value) should be expressed as three digits below zero. If direct indication is difficult to express in the figure, then *, **, *** may be used. Theses asterisks should be explained in the figure legend. Figure format is individualized as follows: photographic images should be submitted in TIFF, JPG (JPEG), PNG, and GIF format with the original high resolution. It should have a minimum width of 100 mm and a minimum resolution of 300 dpi. Neither compression nor change of the color mode should be made. Line arts (graphs and illustrations) should be submitted in native PPT (preferred) including editable figure elements, vector files, or TIFF files (at least 300 dpi with a minimum width of 100 mm).
Supplementary material is peer reviewed material directly relevant to the conclusion of an article that is not included in the printed version owing to space or format constraints. It is posted on the journal's website and linked to the article when the article is published, and may consist of data files, figures, videos or extensive tables. The printed article must be complete and self-explanatory without the supplementary information.
Supplementary material enhances a reader's understanding of the paper but may not be essential to the reader's understanding.
