All authors should have participated sufficiently in the work to take public responsibility for the content. Written approval signed by all authors should be presented with the manuscript.


The manuscript should be submitted online through our email, later on through our website, and the text should be double spaced and have wide margins. The manuscript should be arranged in the following order: 1) Title Page, 2) Keywords, 3) Abstract, 4) Corresponding author, 5) Introduction, 6) Materials and methods, 7) Results, 8) Discussion, 9) Acknowledgments, 10) References, 11) Tables, 12) Figure Legends, and 13) Figures. Please indicate the page your manuscripts to facilitate reviewing.

Title page

The title page should contain, on separate lines, the title of the manuscript, a running title of no more than 40 letters, the name(s) and affiliation(s) of the author(s), and the mailing address, telephone and fax numbers, and E-mail address of the corresponding author. The title must be informative, specific, and concise. Serialization of articles into parts is not permitted; such articles may be submitted independently with self-sufficient titles.

Keywords and Abstract

Provide 3-10 key words or phrases for indexing purposes, using terms from the latest US National Library of Medicine's Medical Subject Headings (MeSH) browser list at ( If appropriate MeSH terms are not available, other suitable terms may be used. Full-length submissions should include an abstract of up to 250 words in structured form, consisting of an Objective, Methods, Results, and Conclusions.


The text should include the following sections. The Introduction summarizes the rationale, provides a concise research background (not an exhaustive review) and states in one sentence the objective of the study. Do not include any results or the conclusions of the study. The Materials and Methods provide technical information about the study. Do not describe methodological details that have been published previously. Specifications (including the manufacturer, city, and the country) should be given for the main drugs, chemicals, and instruments. Indicate the statistical methods used and identify statistical significance using superscripts (a and b) following the data (aP<0.05, bP<0.01). The Results are the findings, using SI units. In a sample, the number of effective digits is determined by the variation within the sample, that is, one-third of the standard deviation. Digits may be separated into groups of three by a small space. The Discussion deals with the interpretation of the results and their comparison with those of other studies. Do not repeat the results, do not review the literature, do not repeat textbook knowledge and do not cite references that do not have a close relationship with the present results. End with a brief conclusion linking back to the aim of the study.


The use of abbreviations, except for units of measure, is discouraged. At the first appearance in the abstract and the text, abbreviations should be preceded by words for which they stand.


Tables must be concise and cited consecutively using Arabic numerals in the text (Table 1, Table 2, etc.). Each table should be typed on a separate sheet. The title of the table should clearly indicate the nature of the contents and sufficient details should be included in the footnote to facilitate interpretation without reference to the text. Use horizontal rules only.


Figures (photographs, drawings, diagrams and charts) should be clear, easily legible and cited consecutively using Arabic numerals in the text (Figure 1, Figure 2, etc.). Please supply figures 1.5 to 2 times the size at which they will be finally reproduced. For line work, submit black-ink drawings of professional quality. Micrographs or other glossy photographs must be of the highest quality. If a figure comprises more than one glossy photograph, these should be marked A, B, C, etc. Figure legends should be marked clearly with the correspond letter. Legends should contain sufficient details to permit figure interpretation without reference to the text. Scale markers should be indicated in the photographs. Color plates are also welcome. The choice of cover art illustration will be made by the Editor.


The Journal advocates the citation of new papers; old references are better replaced with updated ones. The authors are responsible for the correctness of references. References are numbered consecutively in the order in which they appear in the text. Citation should be labelled in superscript parenthesis and should appear in front of the period or comma at the end of the sentence/clause. All references should be cited.

Unpublished data, personal communications, abstracts at meetings and manuscripts submitted for publication are not acceptable as references. Information from such sources may be cited in the text with the sources given in parentheses. References should be listed in numerical order in the Reference section. Journal titles should be abbreviated according to the list of Journals Indexed in Index Medicus or MEDLINE ( Please note that no periods are used after the authors-initials or journal abbreviations. A period is used at the end of each reference. The type and punctuation of references is consistent with the Uniform Requirements for Manuscripts Submitted to Biomedical Journals of the International Committee of Medical Journal Editors ( Some examples are as follows:
