Headings and subheadings (According to APA)  

No heading is needed for the first part of a paper as it is already assumed as the introduction.

Headings and subheadings are not accompanied by letters or numbers.

Use as many levels as required in your paper to present the most organized structure.

The same level of heading or subheading should be of equal importance regardless of the number of subsections under it.

Use at least two subheadings for each section and subsection, or use none.

Start with level 1 through 5.

Paragraph begins below levels 1 and 2, whereas for levels 3-5, the paragraph begins in line with the headings.

Capitalize each word for levels 1 and 2.

Only the first word is capitalized for levels 3-5.


Tables should be included in the main document, presented after the reference list, and they should be numbered consecutively in the order they are referred within the main text. A descriptive title must be placed above the tables. Abbreviations used in the tables should be defined below the tables by footnotes (even if they are defined within the main text). Tables should be created using the “insert table” command of the word processing software and they should be arranged clearly to provide easy reading. Data presented in the tables should not be a repetition of the data presented within the main text but should be supporting the main text.

Figures and Figure Legends 

Figures, graphics, and photographs should be submitted as separate files (in TIFF or JPEG format) through the submission system. The files should not be embedded in a Word document or the main document. When there are figure subunits, the subunits should not be merged to form a single image. Each subunit should be submitted separately through the submission system. Images should be labeled (a, b, c, etc.) to indicate figure subunits. Thick and thin arrows, arrowheads, stars, asterisks, and similar marks can be used on the images to support figure legends. Any information within the images that may indicate an individual or institution should be blinded. The minimum resolution of each submitted figure should be 600 DPI. To prevent delays in the evaluation process, all submitted figures should be clear in resolution and large in size (minimum dimensions: 100× 100 mm). Figure legends should be listed at the end of the main document.

All acronyms and abbreviations used in the manuscript should be defined at first use, both in the abstract and in the main text. The abbreviation should be provided in parentheses following the first time use of the definition.

When a drug, product, hardware, or software program is mentioned within the main text, product information, including the name of the product, the producer of the product, and city and the country of the company (including the state if in USA) should be provided in parentheses in the following format: “Discovery PET/CT scanner (General Electric, Milwaukee, WI, USA)”


All figures should be referred to within the main text, and they should be numbered consecutively in the order they are referred to within the main text.


While citing publications, preference should be given to the latest, most up- to-date publications. Only if an ahead-of-print publication is cited, the DOI number should be provided. Authors are responsible for the accuracy of references. Journal titles should be abbreviated in accordance with the journal abbreviations in Index Medicus/ MEDLINE/PubMed. All authors of the cited articles should be listed at the references section.  In the main text of the manuscript, references should be numbered based on the appearance order in the main text and should be cited using numbers in parentheses. The reference styles for different types of publications are presented in the following examples.
