Available terms can be used if there is no appropriate term for the "Index Medicus" medical subject headings for the newly entered terms

Introduction: The general conditions of the study settings, the structure and significance of the problem, the specific objective of the study or research tested in the study or observation should be clearly indicated. The primary and secondary objectives of the work should be clearly stated and the predefined subgroup analyzes should be transferred. Only references related to the topic should be used and the data or results of the presented work should not be included in these references.

Material and Method: The informed consent of the patient and the approval of the ethics committee should be acknowledged. A statement must be added that the informed consent was obtained from each participant in clinical trials. It should be noted in experimental studies that all animals were subjected to a humane treatment in accordance with the Guide for the Care and Use of Laboratory Animals (
Definition of optimal working conditions, exclusion criteria and referenced population; the participants in the observational or experimental study must be clearly indicated. Since the relevance of the variables such as age and gender for the purpose of the research is not always obvious, the authors should explain the purpose of using these variables in a research article. The main principles that determine how and why the study is performed using such a method should be clear. References should be shown for established methods, brief descriptions should be given for new methods

The methods, tools (manufacturer’s name and address are written in parentheses) and the operations performed should be described in detail to the extent of interpretation of the results. The initials of the drug names should be in lower case, the pharmacological names of the drugs should be used and at their first mention in the text they should be written in brackets in the following order"Generic name, trade name, and Manufacturing firm ". Example: "midazolam (Dormicum, Roche)". The terms should be written in their explicit forms at their first mention in the text, and then their abbreviations ( if any) should be enclosed in parentheses. Frequently used abbreviations should be used as accustomed (iv, im, po and sc). Units must be used in compliance with the International system of units (SIU (Le Système international d'unités),Examples: mg / kg, mL / kg, mL / kg / min, mL / kg

Statistical methods should be provided in sufficient detail so that the readers can reach the original data and evaluate the reported results. Findings should be measured as much as possible and the appropriate margin of error and uncertainty (such as confidence intervals) should be indicated. It is important to avoid relying only on the p-values ??of statistical hypothesis measures that are insufficient to convey important information about the dimensions of the effects. P values ??must be given explicitly. Statistical terms, abbreviations and symbols should be defined. In the last paragraph of this section, statistical analyses used, and the values given by the (±) sign after the arithmetic mean or proportion should be indicated.

Results: The findings, tables and visual material obtained in the study should be written in the order of a certain logic so that the most important ones will take precedence in the text. Graphics, tables, illustrations, and figures should be numbered according to the order of their mention in the text, and should be indicated in parentheses in the text. Data contained in the tables and visual materials should not be repeated in the text. Only important observations should be emphasized or summarized. Tables and figures are placed collectively after the last reference at the end of the text. Only the top title of the table, and graphic or the subheading of figures, illustrations, photos are written in their appropriate places in the text

The numerical results summarized in the Results section should be given not only as derivatives (eg percentages), but with exact numerical values, and the statistical methods used to analyze them should be specified. When scientifically appropriate, data should be analyzed in terms of variables such as age and gender. Tables and pictures should be limited to those necessary to explain and support the discussion expressed in the article. As an alternative to the tables, you should use some kind of graphics on which many entries can be made, and data should not be repeated on graphics and tables. Using non-technical terms such as "random", "explicit", "links" and "example" in the statistics section should be avoided

Discussion: The results of the study are evaluated by comparing them with the international, and domestic literature. New and important aspects of the study and its outcomes should be emphasized. Data and other information presented in the Introduction and Results sections should not be repeated. In experimental studies, we should briefly summarize the main findings and then analyze explanations with possible mechanisms and compare them with other similar studies. It would be appropriate to comment on the implications of these findings for future researches and clinical practices. The objectives of the work should be correlated with the results. However, unmeasured situations and outcomes that are not adequately reinforced by the data should be avoided. The resulting decision arrived must be stated in the last paragraph of the discussion. If the article does not include appropriate economic data and analysis, no particular comment should be made on economic interests and costs. Claims on an incomplete study should be avoided, new hypotheses must be specified when they are confirmed, and their novelty should be clearly emphasized.

Acknowledgment (if any): If you also want to thank the people who can not fulfill the criteria for authorship involved in fundraising, technical assistance, data collection, supervisor of the research group, writing, or department chiefs who just provided general support, and those providing finance and material support, a brief paragraph can be written under the heading of “Acknowledgement.". Written consent must be obtained from the individuals to be mentioned in the acknowledgment section since they may make a sense of data and conclusions they contributed

Conflict of Interest: The authors are requested to declare any existing commercial association that might potentially have a conflict of interest regarding their articles. (eg employment, direct payments, holding shares, holding, consultancy, patent licensing arrangements, or granting honorarium). All financial resources supporting the study should also be declared as footnotes

Tables and Charts: Charts can be saved in a single chart file, tables can be placed in one spreadsheet file on each page. Titles, descriptions and footnotes should be placed on each sheet of paper.
The tables reflect the information in a concise and effective way. They also provide information of the desired quality and precision. The fact that the data are given in the tables rather than in the text usually makes it possible to shorten the text. The tables should not be a repetition of the information in the article

The tables should be demonstrated in brackets in the text. It should carry a short self-heading. According to their appearance in the text, each one should be given a short title, starting from the top left, and numbered sequentially by Roman numerals. There should be no lines on the background, they should be drawn on a white background.. Horizontal and vertical lines should not be used in the table . Each column is given a short or a concise title. Explanatory information should be placed in footnotes, not in headings. Abbreviations should be explained in footnotes. The explanations of the abbreviations should be in the form of subtitles under the table and in alphabetical order. The following symbols should be used in the footnotes, in the following order: *, †, ‡, §, ||, ¶, **, ††, ‡‡. Measures of statistical variables such as standard deviation and standard mean error should be defined. Make sure that each table and graph are mentioned in the text.

There should be no frame around the graphics, no lines on its background, and the background should be white.
When using previously published or electronically published tables and graphics, written permission should be obtained from both the author and the publisher and they should be acknowledged. Permission should be faxed or mailed to the journal editor.

Pictures, Photos and Figures: Figures should be professionally drawn and photographed. Photographs and scans taken with a digital camera should be recorded at a resolution of at least 300 dpi, 1280x960 pixels, in jpg or tiff format. There should be no writing on the picture unless it is compulsory.

Each pictures and figure should be placed on separate pages in a file containing only pictures, figures, and photos . Naming and numbering should be done as subtitles on each page. They should be placed in the text, numbered in Arabic numerals according to the order of their appearance in the text, and shown in brackets in the text When symbols, arrows, or letters that point to specific sections of the figures, and photos are used, these should be explained in the subtitle. If so, the expansions of the abbreviations should be placed under the subtitle in alphabetical order.

Microscope magnification ratio and staining technique used should be explained.
When previously printed or electronically published figures, images, and photos are used, written permission must be obtained from both the author and the printing house and this must be sent by fax or mail to the editor of the journal.

When using the images of people whose face is not hidden and recognizable, written permission must be obtained from them.

References: One should be selective in the use of references, and should include references directly related to the study. Turkish sources should be also used and authors should be sensitive to this issue. Although referencing review articles direct readers to the proper essence of the medical literature, they do not always accurately reflect the original study. Therefore, readers should be provided with as much original research articles as possible. Avoid using summaries as a source.

Authors should compare references with original articles to minimize erroneous references that sometimes occur in published articles. Authors are responsible for the accuracy of refereces and their spelling.
If the authors can not specify whether they referenced a retracted publication or not, they are obliged to check that the references they cited do not belong to the retracted articles. For articles in the journals indexed on MEDLINE, ICMJE considers PubMed ( as a reliable source of information on retracted articles. Authors may recognize the retracted articles in MEDLINE with the following search term in PubMed; retracted publication [pt] ( pt in square brackets stands for publication type).
Apart from collective and up-to-date review articles, encompassing reference lists unnecesarily occupy valuable space of the text. As a general rule, the number of references should be maximum 40 in research articles 15 in case reports, 80 in review articles, 80 in review articles and 5 in editorials.
Exchanges of information during personal contacts, unfinished articles, and other unpublished data should not be referenced.
References should be written double-spaced on a separate sheet of paper. References in the text, tables and figure legends are indicated by Arabic numbers. Only the references used in the table or picture subtitles must be numbered according to the order of their first appearance of the table, and figure in the text.
Journal titles should be abbreviated according to Index Medicus. Year, volume, the first and last pages are indicated for referenced journals, while for referenced books only year, first and the last pages are stated.
The following rules should be followed when references are given in the text:

  1. If the surname of the first author of the article to be cited is to be given, the abbreviation "et al." should be added followed by the reference number in superscript "[]", before completion of the sentence.
  2. If no name is to be given in a sentence, then the reference number must be given at the end of the sentence, after the period in a superscript bracket "[]".
  3. If different references will be stated for different expressions within a sentence, each reference must be given within a bracket "[]" before the punctuation mark at the end of the statement.
  4. If there are more than two consecutive sources exist, then the first and last ones should be indicated with a "-" sign between them, i.e: 1-3]; [14-18]; [8-14]
  5. Full surnames of the authors and the initials of their names should be written in references. If the number of authors in the reference is equal to or less than 6, then all authors should be indicated. . If the number of authors is more than 6, then the first 6 authors should be written before the abbreviation "et al." (for international publications) or "ve ark." (for national publications).
  6. The DOI number must be added at the end of the each reference

The format of writing the references should conform to the "Vancouver reference style". Except for the examples below, the web address should be checked in spelling. (
